This pattern is incompatible with Rust's borrow rules (the closure would need `&mut` to the solver state while the step method already holds `&mut self`). + +Rust replaces all three with `begin_step` / `end_step`: +- `begin_step(complex, solved_rules)` — starts a step, creates internal `CurrentStep` bookkeeping. +- `end_step(rule_indices_to_remove)` — finalizes the step, pushes to history, returns `(Step, num_new_conclusions)`. + +Between these calls, the delegate calls `step_conclude_rune` and `step_add_rule` directly on the solver state. + +## Immediate Commit vs Tentative Buffering (and markRulesSolved) + +Scala had a two-phase commit flow: + +1. `simpleStep`/`complexStep` ran the closure, buffering conclusions inside the `StepState`. The step returned a `Step` object containing those buffered conclusions. +2. `Solver.advance` then called `markRulesSolved(ruleIndices, step.conclusions)` as a **separate call** to actually commit the conclusions into the solver state. `markRulesSolved` returned the count of how many conclusions were genuinely new (vs duplicates of already-known ones). In the complex solve path, `Ok(0)` meant no progress was made. + +Rust collapses this into a single phase: `step_conclude_rune` commits conclusions immediately (visible via `get_conclusion` right away) and increments `CurrentStep.num_new_conclusions` when a conclusion is genuinely new. `end_step` returns that count. There is no separate `markRulesSolved` call from `advance`. + +This is safe because on error, the solver is abandoned entirely (`FailedSolve` returned), so rollback is never needed. + +## ISolveRule Replaced by SolverDelegate + +Scala had `ISolveRule` as the trait for solving logic, plus separate `ruleToPuzzles` and `ruleToRunes` closures passed to the `Solver` constructor. + +Rust combines these into a single `SolverDelegate` trait: +- `rule_to_puzzles(&self, rule) -> Vec>` +- `rule_to_runes(&self, rule) -> Vec` +- `solve(&self, state, env, rule_index, rule, solver_state) -> Result<(), ISolverError>` +- `complex_solve(&self, state, env, solver_state) -> Result<(), ISolverError>` +- `sanity_check_conclusion(&self, env, state, rune, conclusion)` + +Key difference: Scala's `solve` received both `solverState` and `stepState` as separate arguments. Rust's `solve` receives only `solver_state: &mut S` (where `S: ISolverState`) since step operations are now methods on `ISolverState` itself. + +## step_add_rule Takes Puzzles Explicitly + +Scala's `IStepState.addRule(rule)` computed puzzles internally using the `ruleToPuzzles` closure captured by the inner class. + +Rust's `step_add_rule(rule, puzzles)` takes puzzles as an explicit argument. The delegate computes them via `self.rule_to_puzzles(&rule)` before calling `step_add_rule`. This avoids storing closures in the solver state. + +## Solver Struct Owns Delegate and State as Separate Fields + +Scala's `Solver` held `solverState`, `solveRule`, `ruleToPuzzles`, and `ruleToRunes` as separate constructor parameters. + +Rust's `Solver` holds `delegate: D` and `solver_state: SolverStateImpl<...>` as struct fields. Because they are disjoint fields, Rust allows borrowing both simultaneously in `advance()` — the delegate is borrowed immutably while the solver state is borrowed mutably. + +## Compile-Time Solver State Selection + +Scala chose between `SimpleSolverState` and `OptimizedSolverState` at runtime via a `useOptimizedSolver: Boolean` flag. + +Rust uses a compile-time type alias: +```rust +type SolverStateImpl = SimpleSolverState; +``` +Currently hardcoded to `SimpleSolverState`. `OptimizedSolverState` has panic stubs for the new methods. + +## CurrentStep vs Step + +`Step` is the permanent record of a completed step (stored in history, returned via `get_steps()`). `CurrentStep` is a transient wrapper that exists only between `begin_step` and `end_step`, containing the `Step` being built plus a `num_new_conclusions` counter. After `end_step`, the `Step` is pushed to history and `CurrentStep` is discarded. + +## FailedSolve.steps Differs on Conflicts + +Because of the immediate-commit design, `FailedSolve.steps` has different contents when a conflict occurs: + +- **Scala**: `simpleStep`/`complexStep` always pushes the completed step to `steps` when the closure returns `Ok`. Conflict detection happens later in `markRulesSolved`. By the time `FailedSolve` is constructed, `getSteps()` includes the step that produced the conflicting conclusion. +- **Rust**: `step_conclude_rune` detects conflicts immediately. If it fails, the error propagates out of `delegate.solve`, and `end_step` is never called — so the step that produced the conflicting conclusion is not included in `FailedSolve.steps`. + +The conflicting conclusion is still captured in `FailedSolve.error` (the `SolverConflict` variant), so the information isn't lost — it's just not in the step history. + +## ruleToPuzzles: Constructor Closure -> Delegate Method + +Scala passed `ruleToPuzzles` as a separate `Rule => Vector[Vector[Rune]]` closure to the `Solver` constructor, independent of `ISolveRule`. Different `Solver` instances could receive different puzzler closures (e.g. the `predicting` test creates two solvers with different puzzlers via `solveWithPuzzler`). + +Rust folds `rule_to_puzzles` into `SolverDelegate` as a trait method. To vary the puzzler per `Solver` instance, store configuration in the delegate struct (e.g. a closure field or enum variant) rather than passing a separate closure. The capability is preserved but the pattern changes. + +## IRule Sealed Trait -> TestRule Enum + +Scala's `sealed trait IRule` with case classes (`Lookup`, `Literal`, `Equals`, etc.) maps to Rust's `TestRule` enum wrapping the individual structs. The `IRule` trait still exists temporarily for the `all_runes`/`all_puzzles` interface on individual structs, but `TestRule` is what flows through the solver. diff --git

+# Postparser Interning: Dual-Enum Pattern For Lookups (IDEPFL) + +Scala's `Interner` used GC-backed `HashMap[T, T]` to canonicalize case classes. Rust replaces this with arena-backed interning on `ScoutArena<'s>` using two parallel enums per type hierarchy: a **reference enum** (permanent, holds `&'s` pointers to arena data) and a **value enum** (transient, used as HashMap lookup keys). The transient Val exists only to check "does this already exist?" — then it's either discarded (hit) or promoted into permanent arena storage (miss). + +--- + +## The Five Dual-Enum Pairs + +| Permanent Enum (canonical) | Transient Enum (lookup key) | ScoutArena Method | +|---|---|---| +| `IRuneS<'s>` | `IRuneValS<'s, 'tmp>` | `intern_rune()` | +| `IImpreciseNameS<'s>` | `IImpreciseNameValS<'s>` | `intern_imprecise_name()` | +| `INameS<'s>` | `INameValS<'s>` | `intern_name()` | +| `IFunctionDeclarationNameS<'s>` | `IFunctionDeclarationNameValS<'s>` | via `INameS` | +| `IVarNameS<'s>` | `IVarNameValS<'s>` | via `INameS` | + +Note: `IRuneValS` has a second lifetime `'tmp` because some of its variants contain transient slice data (see @DSAUIMZ). The other Val enums don't have slices yet, so they use only `'s`. + +--- + +## How They Differ + +The **permanent enum** holds `&'s` references to arena-allocated payloads: + +```rust +pub enum IRuneS<'s> { + CodeRune(&'s CodeRuneS<'s>), + ImplicitRune(&'s ImplicitRuneS<'s>), + ImplicitRegionRune(&'s ImplicitRegionRuneS<'s>), + // ... +} +``` + +The **transient enum** holds payload structs by value for HashMap lookup. The `'tmp` lifetime borrows from stack temporaries, not the arena (see @DSAUIMZ): + +```rust +pub enum IRuneValS<'s, 'tmp> { + CodeRune(CodeRuneS<'s>), // simple: same struct, no slice + ImplicitRune(ImplicitRuneValS<'tmp>), // transient: borrows slice via 'tmp + ImplicitRegionRune(ImplicitRegionRuneValS<'s>), // shallow: holds canonical refs + // ... +} +``` + +--- + +## Why Both Exist + +You can't skip the transient Val enum because: + +1. The permanent enum contains `&'s` pointers — you can't construct one without first allocating into the arena. +2. You need a hashable key to check whether a value was already interned. +3. If you allocated into the arena first and then checked, you'd waste arena space on duplicates. The transient Val avoids this — it lives on the stack and costs nothing to discard on a hit. + +--- + +## Interning Flow + +1. **Build a transient Val** — construct an `IRuneValS<'s, 'tmp>`. For variants with slices, borrow from a stack-local builder (see @DSAUIMZ). For scalar variants, just fill in the fields. +2. **Look it up** — the scout arena checks `hashbrown::HashMap, IRuneS<'s>>` using a `RuneValQuery` wrapper for heterogeneous lookup. If found, return the existing permanent `IRuneS`. The transient Val is discarded — zero arena cost. +3. **Promote if new** — on a miss, promote the transient Val to permanent: arena-allocate any slices via `promote_in()`, allocate the payload struct, wrap the `&'s` ref in the corresponding `IRuneS` variant, store the mapping, return it. + +```rust +// Caller builds a transient Val that borrows from the builder's stack Vec: +let rune = self.scout_arena.intern_rune( + IRuneValS::ImplicitRune(ImplicitRuneValS::new(lidb.child().borrow_val())) +); +// On HIT: the transient Val is discarded, nothing allocated +// On MISS: the path slice and ImplicitRuneS are arena-allocated +// Either way, rune is IRuneS::ImplicitRune(&'s ImplicitRuneS) +``` + +--- + +## Internable Units + +A Val struct defines an **internable unit** — the boundary around everything that gets interned together atomically. The Val is what you hash and look up. Its inner data falls into two categories: + +- **Already-permanent references** to other interned types (`IRuneS<'s>`, `StrI<'s>`, `INameS<'s>`) — pointers to data from a previously-promoted internable unit. Free to copy. +- **Owned transient data** — slices or primitives unique to this unit. Borrowed from the stack via `'tmp`, promoted to the arena only on a miss. + +`Val` in the name marks an internable unit boundary. Types without `Val` (like `LocationInDenizen`, a bare slice) are **parts** of their owning unit — they get arena-allocated when the unit is promoted, not before (see @DSAUIMZ). + +--- + +## Three Kinds of Val Variants + +### Simple: same struct in both enums + +When a payload struct contains only simple/Copy fields (like `StrI<'s>`), the transient Val enum holds the same struct type by value. No separate Val struct is needed: + +- `IRuneS::CodeRune(&'s CodeRuneS<'s>)` — permanent +- `IRuneValS::CodeRune(CodeRuneS<'s>)` — transient (same struct, trivially cheap) + +### Shallow: separate Val struct for nested interned types + +When a payload struct contains references to *other* interned types, a separate Val struct exists. The Val struct holds the child as an already-canonical owned `IRuneS<'s>` (it's "shallow" — children must be interned first): + +```rust +// Permanent payload (lives in arena): +pub struct ImplicitRegionRuneS<'s> { + pub original_rune: IRuneS<'s>, +} + +// Transient lookup key (for HashMap): +pub struct ImplicitRegionRuneValS<'s> { + pub original_rune: IRuneS<'s>, +} +``` + +The fields look identical in this case, but they're separate types so the type system enforces going through the scout arena. You can't accidentally use a Val where a canonical ref is expected. + +Note: `IRuneS<'s>` is already just a tagged pointer (discriminant + `&'s` to arena payload), so holding it owned vs `&'s IRuneS<'s>` is storing the tagged pointer directly vs a pointer-to-a-pointer. Owned is simpler and equally cheap. Identity is checked via `IRuneS::ptr_eq`/`canonical_ptr` which look at the inner payload pointer. + +Other shallow Val structs follow the same pattern: +- `ImplicitCoercionOwnershipRuneValS` — holds `IRuneS<'s>` for its child rune +- `AnonymousSubstructImplDeclarationNameValS` — holds `&'s TopLevelInterfaceDeclarationNameS<'s>` +- `ImplImpreciseNameValS` — holds two `IImpreciseNameS<'s>` children +- `ForwarderFunctionDeclarationNameValS` — holds `IFunctionDeclarationNameS<'s>` + +**Rule**: intern children first, then build the parent Val with canonical child runes. + +### Transient with `'tmp`: Val struct that defers slice allocation + +Per @DSAUIMZ, when a payload struct contains a slice (like `LocationInDenizen { path: &'s [i32] }`), the transient Val holds a **borrowed** version of that slice via a `'tmp` lifetime, not an arena-allocated one. The slice is only arena-allocated inside the intern method on a miss. + +```rust +// Permanent payload (lives in arena): +pub struct ImplicitRuneS<'s> { + pub lid: LocationInDenizen<'s>, // path: &'s [i32] — arena-allocated +} + +// Transient lookup key (borrows from stack): +pub struct ImplicitRuneValS<'tmp> { + lid: LocationInDenizenVal<'tmp>, // path: &'tmp [i32] — borrows builder's Vec +} +``` + +The transient Val's fields are **private** — constructible only via `borrow_val()` which ties `'tmp` to a stack-local `LocationInDenizenBuilder`. This privacy ensures callers cannot accidentally pre-allocate the slice in the arena. + +The `'tmp` lifetime is what makes the Val truly transient: it borrows from a local that dies when the function returns, so the Val physically cannot outlive its intended check-and-discard purpose. + +Seven rune variants use this pattern: `ImplicitRuneValS`, `PureBlockRegionRuneValS`, `CallRegionRuneValS`, `CallPureMergeRegionRuneValS`, `LetImplicitRuneValS`, `MagicParamRuneValS`, `LocalDefaultRegionRuneValS`. + +--- + +## Identity via `ptr_eq` + +The canonical enums provide `ptr_eq()` and `canonical_ptr()` methods. Since the scout arena guarantees structurally equal values get the same arena allocation, pointer equality is identity equality: + +```rust +impl<'s> IRuneS<'s> { + pub fn canonical_ptr(&self) -> *const () { /* extracts inner &'s pointer */ } + pub fn ptr_eq(&self, other: &IRuneS<'s>) -> bool { + std::ptr::eq(self.canonical_ptr(), other.canonical_ptr()) + } +} +``` + +This mirrors Scala's `eq` (reference equality) after interning. + +--- + +## Conversion: Ref → Val + +`IFunctionDeclarationNameS` provides `to_val()` for converting a canonical reference back to a value key. This is used when you have an existing canonical name and need to build a parent Val that wraps it. + +--- + +## What Scala Had + +In Scala, all of these were just `case class`es extending `sealed trait`s with `IInterning`. The `Interner` used `HashMap[T, T]` where the JVM's GC managed memory and `eq` gave reference identity. There was no transient/permanent distinction — the GC handled discarding duplicates silently. Rust splits each sealed trait into two enums to make the transient/permanent boundary explicit: transient Vals for lookup, permanent refs for storage. diff --git a/.claude/rules/postparser/postparser-migration-guidelines.mdc b/.claude/rules/postparser/postparser-migration-guidelines.mdc new file mode 100644 index 000000000..e64292bb0 --- /dev/null +++ b/.claude/rules/postparser/postparser-migration-guidelines.mdc @@ -0,0 +1,26 @@ +--- +description: Guidelines to follow and things to allow in the Scala->Rust migration for the post-parser in src/postparsing +paths: src/postparsing/*.rs +--- + +# PostParser Migration Guidelines + +Look at the below allowable differences. + +# Rust vs Scala Allowable Differences + + * Rust functions can have these extra parameters: + * `Interner` + * `Keywords` + * `PostParser` + * It's okay if the Rust version doesn't have these parameters: + * `ExpressionScout` (the function receives the full `PostParser` instead, which contains it) + * `FunctionScout` (the function receives the full `PostParser` instead, which contains it) + * Rust can intern things more than Scala if it decides to.

It can take a few minutes on a fresh clone. + +--- + +## Step 4: Verify submodule branches + +Most submodules sit on `main`, but **`Guardian/opencode` is on a non-`main` branch** — `verdagon-lsp-context-defs`. The recursive update should put it there automatically (the branch is recorded in `Guardian/.gitmodules`), but verify: + +```bash +git submodule foreach --recursive 'echo "$name: $(git rev-parse --abbrev-ref HEAD)"' +``` + +Expected output: + +``` +Guardian: main +ContextifiedDiff: main +Luz: main +ContextifiedShield: main +Luz: main +Luz: main +Rabble: main +Luz: main +ShieldFile: main +Luz: main +opencode: verdagon-lsp-context-defs +Luz: main +``` + +Note the multiple `Luz:` lines — that's because Guardian, ContextifiedDiff, ContextifiedShield, Rabble, ShieldFile, and the top-level repo each include `Luz` as a submodule independently. They may sit on different SHAs of the Luz `main` branch; that's by design. + +If any submodule shows a different branch (e.g. `(HEAD detached at )`), force it to its tracked branch: + +```bash +git -C checkout +``` + +--- + +## Step 5: Verify the `.cargo/config.toml` is in place + +The repo ships a `.cargo/config.toml` that sets `RUST_MIN_STACK=16777216` (16 MB stack for `#[test]` threads — the default 2 MB is too small for debug-mode runs on real Vale programs). After the pull this file should exist: + +```bash +cat /Volumes/V/Vale/.cargo/config.toml +``` + +If it's empty or missing, something went wrong with the pull — re-run Step 2. + +--- + +## Step 6: Build and test + +```bash +cd /Volumes/V/Vale +cargo build --manifest-path FrontendRust/Cargo.toml --lib > tmp/catchup-build.txt 2>&1 +tail -20 tmp/catchup-build.txt +``` + +Expected: clean build, two pre-existing warnings in `expression_compiler.rs` (`unreachable expression` + `unreachable pattern`). No errors. + +Then run the test suite: + +```bash +cargo nextest run --manifest-path FrontendRust/Cargo.toml --lib > tmp/catchup-tests.txt 2>&1 +grep "Summary" tmp/catchup-tests.txt +``` + +Expected: `Summary [..s] 760 tests run: 760 passed, 0 skipped`. + +If a test fails, save the full output (`tmp/catchup-tests.txt`) and check the failure against the current state of `TL.md` ("Where We Are" section) — the suite is supposed to be fully green on `rustmigrate-z`. + +--- + +## Step 7: Sanity-check the workflow files + +These are the files the migration workflow lives in. Read them before touching code: + +- **`TL.md`** — TL handoff / migration state. Read top-to-bottom. Re-read after every compaction. +- **`for-tl.md`** — JR escalation queue. Check at the start of every turn. +- **`for-jr.md`** — TL's responses to JR. JR picks up from here between turns. +- **`CLAUDE.md`** — project-level Claude Code rules (no `cd && cargo`, no temp programs, etc.). +- **`docs/architecture/typing-pass-design-v3.md`** — typing-pass migration design doc. + +The `/Volumes/V/Sylvan` checkout uses these files canonically; `/Volumes/V/Vale` should treat the same files as canonical too — don't fork them. + +--- + +## Step 8: Optional — rename the working directory + +The repo expects no specific working-directory name (`/Volumes/V/Vale`, `/Volumes/V/Sylvan`, and other names all work). If you want to match the convention I've been using on my side: + +```bash +mv /Volumes/V/Vale /Volumes/V/Sylvan +``` + +…but **this is purely cosmetic**. The Cargo manifests use relative paths; no script depends on the parent directory's name. Skip this if it's disruptive. + +--- + +## Troubleshooting + +**"fatal: remote error: upload-pack: not our ref"** during `submodule update`: +A submodule pointer in the parent references a SHA that hasn't been pushed to that submodule's origin. Run `git submodule sync --recursive` then retry, or `cd` into the specific submodule and `git fetch origin` manually. + +**`git checkout rustmigrate-z` says "would overwrite local changes"**: +Step 0 caught something. Stash or commit before retrying. + +**`cargo nextest` fails on `typing_pass_on_roguelike` with a stack-overflow**: +The `.cargo/config.toml` from Step 5 isn't being picked up. Cargo only reads `.cargo/config.toml` from the directory it's invoked from (and parents). If you're running from a deeper subdirectory like `FrontendRust/`, that's fine — Cargo walks up. But if Cargo is being invoked through a tool that overrides `CARGO_HOME` or similar, the config may be ignored. Confirm with `cargo run --manifest-path FrontendRust/Cargo.toml --bin -- --print-env | grep STACK` or set `RUST_MIN_STACK=16777216` manually in the shell. + +**Guardian shields fire on every edit**: +Guardian is the active code-review system for this migration. If a shield is wrong, the fix is to amend the shield (`Luz/shields/.md`) or to escalate the case (`Guardian//cases/need-…/`), not to disable Guardian globally. Read `Luz/skills/guardian-*.md` for the workflow. + +**The submodules are *huge***: +Yes. Guardian alone carries 5 nested submodules. A fresh checkout is ~600 MB. If you don't need Guardian (e.g. read-only browsing), you can skip `--recurse-submodules` and the parent repo alone is small. But for code review or running tests with Guardian active, you need them all. + +--- + +## Quick-reference: one-line catchup + +If your `/Volumes/V/Vale` checkout has nothing local to save, the entire catchup collapses to: + +```bash +cd /Volumes/V/Vale && \ + git fetch origin --prune && \ + git checkout rustmigrate-z && \ + git pull --ff-only origin rustmigrate-z && \ + git submodule update --init --recursive --progress && \ + cargo nextest run --manifest-path FrontendRust/Cargo.toml --lib +``` + +If that prints `Summary [..s] 760 tests run: 760 passed, 0 skipped`, you're in sync. diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 000000000..0ebf9d582 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,225 @@ +# Frontend Rust - Scala to Rust Migration Project + +This is a Rust compiler frontend being migrated from Scala.

Respect the lifetime invariants - see the rules for guidance when rustc complains + +## Agent Rules + +**Never use spawned agents (the Agent tool) to make code modifications.** All edits must be made directly by the main conversation using Read/Edit/Write tools. Spawned agents may only be used for **read-only tasks**: searching, exploring, analyzing, reading files, running read-only commands. The only exception is agents defined in `.claude/agents/` which are explicitly human-written and approved for modifications. + +**When spawning any agent**, the prompt must include clear instructions that the agent **must not modify any files in this project** — only the main conversation and the human are allowed to do that. Agents are free to create and read/write temporary files in `/tmp` for their own use. + +## Notes + +- **Interning:** Rust interns more aggressively than Scala. This is intentional and allowed. +- **Panics:** `panic!()` placeholders are acceptable during mid-migration. Scala's `vimpl` maps to Rust `panic!`. +- **Naming:** Rust uses `snake_case` (e.g., `self_uses`) vs Scala's `camelCase` (e.g., `selfUses`). +- **Profiling:** Rust doesn't need Scala's `Profiler.frame(() => { ... })` wrappers. + + +## Bulk Sed Safety Protocol + +Before running any `sed` command that modifies files in bulk, **always sanity-check first**: + +1. **Identify false positives in the target.** The pattern you're replacing may appear in contexts you don't intend to change: + - **Char literals**: `'a'` looks like lifetime `'a` followed by `'`. Use `s/'a\([^']\)/'p\1/g` to skip char literals. + - **Scala block comments**: This codebase has extensive `/* ... */` Scala code. Search inside block comments for your pattern: `python3 -c "import re; ..."` to extract comment blocks and grep within them. + - **String literals**: Your pattern might appear inside `"..."` strings. + - **Different semantic contexts**: e.g., `'a` in the solver directory is a local callback lifetime, NOT the interner — don't rename it. + +2. **Dry-run on representative files.** Pipe through sed without `-i` and diff or grep the output: + ```bash + sed "s/pattern/replace/g" file.rs | grep "unexpected_thing" + ``` + +3. **Check for collateral damage after the run.** For lifetime renames like `'a` → `'p`: + - Look for duplicated params: `grep -rn "'p, 'p"` (from collapsing `'a, 'p`) + - Look for corrupted char literals: `grep -rn "'p'"` where the original had `'a'` + - Look for changes inside block comments that shouldn't have been touched + +4. **Scope your sed precisely.** Run per-directory or per-file, not blanket across the whole repo. Different directories may need different replacements (e.g., `'a` → `'p` in parsing vs `'a` → `'s` in postparsing). + + +## Build & Run Convention + +Always pipe `cargo run`, `cargo test`, `cargo build`, `cargo check`, and all `sbt` output into a fixed file in `./tmp/` (use the same file for the entire session/project, e.g. `./tmp/refactor-project.txt`). Come up with a name instead of refactor-project.txt, and then use the same file for the rest of the session. + +**Never chain a heavy command with `| tail`, `| head`, `| grep`.** Run the build/test with `>` as one command (redirecting fully to the file) and the inspection as a separate follow-up command. Chaining defeats the purpose: you lose the ability to re-analyze a different part of the output without re-running the expensive build. + +DO have them in separate commands: + +```bash +cargo run --bin benchmark -- --model openai/gpt-oss-20b > ./tmp/fixing-bug-1047-quest.txt 2>&1 +tail -20 ./tmp/fixing-bug-1047-quest.txt +# Later, to see a different part: +head -40

'testOnly dev.vale.AfterRegionsIntegrationTests' > ./tmp/fixing-borrowing-test.txt 2>&1 +grep "SUCCESS" ./tmp/fixing-borrowing-test.txt +``` + +DON'T chain them together like this: + +```bash +# This is bad: +cargo build --lib > ./tmp/build4.txt && grep -B2 "i_env_entry" ./tmp/build4.txt | grep "src/" | head -20 +``` + +Instead, they must be separate entire commands. + +DON'T use a different file

enough to check "does this already exist in the arena?" and are then either discarded (hit) or promoted into permanent arena storage (miss). When a transient Val contains a slice, that slice must also be transient: borrowed from the stack, not pre-allocated in the arena. If the slice were arena-allocated before the intern check, a hit would leave dead arena space that can never be freed. + +The `'tmp` lifetime encodes transience.

The Val is what you hash and check the map for.

Types *without* `Val` — like `LocationInDenizen`, a bare `&[i32]` slice, a `HashMap` — are **parts** of their owning internable unit.

The canonical example is the typing pass's expression hierarchy: `ReferenceExpressionTE`, `AddressExpressionTE`, `ExpressionTE`, and the ~50 per-variant struct types (`UnletTE`, `BlockTE`, `ConstantIntTE`, etc.) — Scala has 52 `vcurious` overrides on these in `ast/expressions.scala`. Rust mirrors this by **not deriving or impl-ing** `PartialEq`/`Hash` at all. Misuse fails at compile time, which is strictly stronger than Scala's runtime panic. + +These types are still `/// Arena-allocated` per @TFITCX — they're stored in the arena for memory/lifetime reasons (large, deeply nested expression trees holding `&'t` child pointers). They just don't carry identity semantics: two distinct allocations of the same expression are neither `==` (no impl) nor distinguishable by identity (nothing compares them). The opt-out applies to the type itself and propagates: a wrapper holding `&'t ReferenceExpressionTE` (e.g. `ExpressionTE`) also can't `derive(PartialEq)` because the derive would try to call the inner's missing eq. + +**When to opt out:** check the Scala counterpart. If every case class in the hierarchy has `vcurious()` equals/hashCode overrides, mirror it as no-impl in Rust.

A polyvalue enum is two words: discriminant + payload word. Same layout, same Copy-by-value passing convention, same equality regime ("two copies that point at the same thing should compare equal regardless of where on the stack they sit"). + +The only difference is *how dispatch works*: `&dyn Trait` is open-set (vtable lookup); a polyvalue enum is closed-set (`match` on the discriminant). We pick closed-set when we know all variants at compile time and want match-based codegen. The runtime shape and equality semantics are isomorphic to `&dyn Trait`. + +## Per-variant ref-or-value + +Each variant chooses whether its payload is a reference or an inline value based on whether the payload carries identity: + +- **Has identity (Arena-allocated or interned)** → the variant payload is a non-owning ref (e.g. `Citizen(&'t CitizenEnvironmentT)`) or a canonical-handle wrapper (e.g. `IdT`). Inlining the raw struct would defeat the identity seal — two copies of the inlined bytes would each be "a different thing." +- **No identity (small Copy primitive)** → inline by value (e.g. `MutabilityTemplataT(MutabilityT)`). The pointer would be dead weight; the value *is* the information. + +Same enum, same layout, same calling convention — different per-variant choices. `IEnvEntryT` is the textbook example: four variants hold `&'s` refs to identity-bearing AST (Function, Struct, Interface, Impl), one variant holds an `ITemplataT` (itself a polyvalue). No exception, no special case — the same per-variant rule. + +A consequence worth naming: a polyvalue can (directly or indirectly) contain references to things that have identity. That's expected — `IdT` already does, and any polyvalue wrapping `IdT` does too. Identity propagates through the layers. + +## The eq/hash trap + +Hand-rolling `std::ptr::eq(self, other)` on the outer `&self` of a polyvalue **silently breaks under by-value use**. + +While the wrapper is always held behind `&'t Outer`, the outer address *is* the stable arena address — ptr-eq on the outer happens to coincide with ptr-eq on the inner. The moment the wrapper gets flipped to by-value, `self` becomes a stack address. Two by-value copies of `IEnvironmentT::Citizen(same_arena_ref)` sit at different stack addresses, compare unequal, hash to different buckets, and silently corrupt any `HashMap` or `HashSet` keyed on them. It compiles, it doesn't panic — it just gives wrong answers. + +**Rule:** polyvalue enums must `#[derive(PartialEq, Eq, Hash)]`. Never hand-roll on the outer `&self`. + +**Why the derive is correct.** The derived `eq` matches on the variant and calls `PartialEq::eq` on each payload. For ref payloads, that desugars to `::eq(&*x, &*y)`; the inner type's `eq` (per @IEOIBZ) does the right identity comparison. For inline-value payloads, structural eq is the right thing. The chain bottoms out correctly in both cases. + +**If you must hand-roll** (e.g. some variants have payloads that can't derive): `match` on the variant pair and `ptr::eq` the **inner** refs, never the outer `&self`.

The mutation-vs-not question is settled first by `docs/architecture/arenas.md` — arenas are immutable, so anything that mutates uses Box / non-arena container / by-value patterns and never reaches this framework. + +## Arena vs Inline: Seven Principles + +Default: store inline as a Copy value-type. Promote to arena-allocated (accessed via `&'t T`) if any of the following holds. + +1. **Size.** ≤128 bits → inline. Larger → arena. Copying a large value at every callsite is wasteful; arena allocation lets every reference be a thin pointer. + +2. **Dynamic length.** Slices and collections of unknown compile-time length must be arena-allocated (`&'t [T]`). Inline storage would require a heap `Vec`, which violates AASSNCMCX in arena-allocated parents. + +3. **Interned.** If the value should deduplicate (two structurally equal instances must share a pointer for fast `ptr::eq`), the payload must be arena-allocated. The wrapper enum that names it can still be stored inline — `IRuneS<'s>` is a tagged pointer (Copy, inline) whose `&'s CodeRuneS<'s>` payload lives in the arena. + +4. **Identity.** If two distinct allocations are distinct *things* (not just equal values), the type must be arena-allocated. Per @IEOIBZ, identity types use `std::ptr::eq` for equality, which requires stable arena addresses. The expression hierarchy (`ReferenceExpressionTE`, `AddressExpressionTE`, etc.) is the canonical case — each instance is a distinct AST node even if structurally equal. + +5. **Sharing.** If multiple parents hold the same value, arena-allocate so the shared refs are cheap copies of `&'t T`. Single-owner trees can stay inline. Interning is a special case of sharing — the interner *is* the sharing mechanism. + +6. **Recursion.** Recursive types must arena-allocate at the recursion edge, otherwise the type has infinite size. `IEnvironmentT` holding `parent: &'t IEnvironmentT` is the canonical case. + +7. **Back-pointers (`&'t self` methods, design v3 §3.4a).** If methods on the type need to emit `&'t Self` (wrap-self, embed-self in a child's `parent` field), the receiver must live in the arena. You can't hand out a `&'t` borrow into a stack value or `Vec` interior. + +If none of the seven apply, the value stays inline as a Copy value-type. `CoordT`, `OwnershipT`, `RegionT`, `RangeS`, `CodeLocationS` are examples — small, no subcollections, single-owner, no identity, no recursion, no back-pointers. + +**Definitional components are arena-allocated.** Types like `ParameterT` and `NormalStructMemberT` don't have independent identity, but they *define* part of an identity-bearing output (`FunctionHeaderT`, `StructDefinitionT`). They are the parameter, they are the member — not a reference to one. They're arena-allocated along with their parent (typically as an inline element of an arena slice the parent owns). The test: if something *is* part of a definition, it's arena-allocated; if it *refers to* a definition, it's a value (and may be interned per the rules below). + +## When Arena-Allocated Becomes Interned + +Once a value is arena-allocated, the next question is whether to intern it (deduplicate via `intern_*` so structurally equal values share a pointer) or just allocate it (each `arena.alloc` produces a distinct allocation). Intern when any of these holds: + +1. **Subcollections.** If the value contains a variable-length collection (like a list of template args or parameter types), interning lets the collection live as an arena slice (`&'t [T]`) inside the interned payload, avoiding heap allocation entirely. + +2. **Size.** If the value is large enough that copying it repeatedly through the wrapper would be expensive, interning stores it once and the wrapper becomes a thin `&'t` pointer. + +3. **Enum budget.** If the value is stored as a variant in a Copy enum (`KindT`, `ITemplataT`), the enum's size is its largest variant. Interning the payload behind `&'t` keeps every variant pointer-sized, keeping the enum small and Copy. This is why `StructTT` and `CoordTemplataT` are interned even though they're individually small — they live inside `KindT` and `ITemplataT` respectively. + +If none apply, the arena-allocated type stays uninterned (each `arena.alloc` is a fresh distinct allocation). Identity types — definitions, environments, expression nodes — are arena-allocated and *never* interned, because their whole point is that each allocation is a distinct thing. Interning would erase identity. + +## Scala Parity Overrides The Heuristics + +Rust's Interned set is anchored to Scala's `IInterning` trait — types that extend `IInterning` in Scala (sealed traits `INameT` and `ICitizenTT`, plus `StaticSizedArrayTT`, `RuntimeSizedArrayTT`, `OverloadSetT`) are Interned in Rust. Types that don't (the Templata variants, `SignatureT`, `PrototypeT`, `KindPlaceholderT`) stay as Value-types or arena-allocated-non-interned per @TFITCX even when they superficially fit one of the heuristics above.

A colleague started this and merged the first 11 sub-compilers onto `Compiler`. Your job is to keep going, one sub-compiler at a time, until the list is done. Then hand off to whoever does macros and the Step 8 cleanup. + +**Read `handoff-god-struct-refactor.md` first.** That's the master plan. This doc is the "continuation" — status, patterns I converged on, gotchas I hit, and exactly what to do next. The master plan describes the "what" and "why"; this doc tells you what's *done* and the practical "how" you'll need to execute cleanly. + +## 90-second catch-up + +- **Project:** Rust port of a Scala compiler frontend. The typing pass (`FrontendRust/src/typing/`) is being collapsed from ~20 separate `FooCompiler` structs into one `Compiler<'s, 'ctx, 't>` god struct. +- **Method bodies are almost all `panic!()` stubs.** This refactor is structural: move method signatures from `impl FooCompiler` blocks into `impl Compiler` blocks. You're almost never reading real logic. +- **The audit trail matters.** Every Rust definition sits next to its `/* scala */` comment block. The pairing is enforced by a pre-commit hook. Don't break it. +- **The god struct has four fields**, nothing else: + ```rust + pub struct Compiler<'s, 'ctx, 't> + where 's: 't, + { + pub scout_arena: &'ctx ScoutArena<'s>, + pub typing_interner: &'ctx TypingInterner<'t>, + pub keywords: &'ctx Keywords<'s>, + pub opts: &'ctx TypingPassOptions<'s>, + } + ``` + `global_env` and `name_translator` are **not** on it — see the master handoff for why. + +## Status as of last commit + +On branch `rustmigrate-z`. `cargo check --lib` is **clean** (0 errors, 0 warnings — `src/lib.rs` sets `#![allow(unused_variables, unused_imports)]`). Phase 2 (god-struct refactor) is complete: all 8 upper-tier sub-compilers merged, all 15 macros merged, and Step 8 cleanup done (vestigial `ArrayCompiler`, `InferCompiler`, `TemplataCompiler`, `ImplCompiler`, `StructCompiler`, `DestructorCompiler`, `ExpressionCompiler`, `NameTranslator`, `ConvertHelper`, `OverloadResolver`, `CompilerSolver` PhantomData structs deleted). Only `Compiler` itself remains as a real type; the other `*Compiler` names are now just `// mig: struct` markers with Scala comments beneath. The `IInfererDelegate` trait is still kept vestigial because fn signatures in `compiler_solver.rs` reference it as `&dyn IInfererDelegate<'s, 't>`; that goes away when those fn signatures get rewritten in a later phase. Next phase is body migration — filling in the typing-pass skeleton per `quest.md` §12 (Slabs 1–6). + +**Known cleanup debt:** the `// mig: struct` / `// mig: enum` / `// mig: fn` / `// mig: impl` / `// mig: trait` markers are slice-pipeline artifacts and can be deleted entirely. Slicing is done; the `/* scala */` blocks remain as the audit trail (and are what the pre-commit hook enforces) — the `// mig:` lines add nothing. The Slab 2 handoff (`handoff-slab-2.md`) schedules this cleanup as a Step 0 prereq: sweep `src/typing/` and delete every `// mig:` line.

Then Step 8 cleanup (see master handoff). + +## The macros pattern — how to do one macro + +Macros are different from sub-compilers in one way: they're dispatched dynamically (stored in the global env, looked up by generator id). But the shape is the same — all state has already been hoisted onto `Compiler`, so the macro struct has nothing real left in it. We collapse them onto `Compiler` the same way we did sub-compilers, plus wire a per-trait unit-variant enum as the dispatch tag. + +### The four dispatch enums + +Scala has four macro traits. Each becomes a unit-variant enum in Rust (`src/typing/compiler.rs` or a new `src/typing/macros/macros.rs` — same place the current `IFunctionGenerator` stub lives): + +```rust +pub enum FunctionBodyMacro { + LockWeak, + AsSubtype, + StructDrop, + InterfaceDrop, + StructConstructor, + AbstractBody, + SameInstance, + RsaLen, RsaMutableNew, RsaImmutableNew, RsaDropInto, + RsaMutableCapacity, RsaMutablePop, RsaMutablePush, + SsaLen, SsaDropInto, + // (only macros that extend IFunctionBodyMacro in Scala — roughly the list above) +} +pub enum OnStructDefinedMacro { StructConstructor, StructDrop, SameInstance, /* ... */ } +pub enum OnInterfaceDefinedMacro { /* ... */ } +pub enum OnImplDefinedMacro { /* ... */ } +``` + +A given macro (e.g. `StructDropMacro`) appears in multiple enums iff Scala had it extending multiple traits. These are Copy unit enums — cheap, no lifetimes. + +### Per-macro per-method transformation + +For each macro file `src/typing/macros/.../foo_macro.rs`: + +**Before (the slice-pipeline output we inherited):** + +```rust +// mig: struct FooMacro +pub struct FooMacro<'s, 'ctx, 't> { + pub keywords: Keywords<'s>, + pub expression_compiler: ExpressionCompiler<'s, 'ctx, 't>, // or other sub-compilers + pub destructor_compiler: DestructorCompiler<'s, 'ctx, 't>, +} +// mig: impl FooMacro +impl<'s, 'ctx, 't> FooMacro<'s, 'ctx, 't> {} +/* +class FooMacro(keywords: Keywords, expressionCompiler: ExpressionCompiler, ...) extends IFunctionBodyMacro { +*/ +// mig: fn generate_function_body +fn generate_function_body<'s, 't>( + env: &FunctionEnvironmentT<'s, 't>, + coutputs: &CompilerOutputs<'s, 't>, + /* ... */ +) -> (FunctionHeaderT<'s, 't>, ReferenceExpressionTE<'s, 't>) { + panic!("Unimplemented: generate_function_body"); +} +/* scala body */ +``` + +**After:** + +```rust +// mig: struct FooMacro +// (Scala class fields absorbed by Compiler; all logic lives on impl Compiler.) +/* +class FooMacro(keywords: Keywords, expressionCompiler: ExpressionCompiler, ...) extends IFunctionBodyMacro { +*/ +// mig: fn generate_function_body +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn generate_function_body_foo( + &self, + coutputs: &mut CompilerOutputs<'s, 't>, + env: &FunctionEnvironmentT<'s, 't>, + /* ... same params as before, minus the sub-compiler fields ... */ + ) -> (FunctionHeaderT<'s, 't>, ReferenceExpressionTE<'s, 't>) { + panic!("Unimplemented: generate_function_body_foo"); + } +/* scala body */ +} +``` + +**What changed:** + +1. **Struct deleted entirely.** The `pub struct FooMacro<'s, 'ctx, 't> { ... }` goes away — nothing Rust-level holds it (the sub-compiler fields it held are all already merged). The `// mig: struct FooMacro` marker stays so the audit trail is preserved; add a `//` note explaining the fields absorbed into `Compiler`. +2. **Empty `impl FooMacro<'s, 'ctx, 't> {}` deleted.** +3. **Every Scala instance method (`generateFunctionBody`, `onStructDefined`, etc.) wraps into its own per-fn `impl Compiler` block**, exactly like sub-compiler methods. The method name gets a suffix derived from the macro name to avoid collisions (every `FunctionBodyMacro` has a `generateFunctionBody` in Scala). +4. **Name suffix convention:** strip the `Macro` suffix from the macro name and lower-snake. `LockWeakMacro.generateFunctionBody` → `generate_function_body_lock_weak`. `RSADropIntoMacro.generateFunctionBody` → `generate_function_body_rsa_drop_into`. `StructConstructorMacro.onStructDefined` → `on_struct_defined_struct_constructor`. Keep it verbose — readability beats brevity for audit-trail grep. +5. **Companion object helpers stay as free fns** (same rule as sub-compilers — see Gotcha 4). + +### Dispatcher methods on `Compiler` + +One dispatcher per Scala trait, wired in `src/typing/compiler.rs` or alongside the enums. These exist solely to turn a `FunctionBodyMacro` tag into the correct `generate_function_body_*` call: + +```rust +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't { + pub fn dispatch_function_body_macro( + &self, + which: FunctionBodyMacro, + coutputs: &mut CompilerOutputs<'s, 't>, + env: &FunctionEnvironmentT<'s, 't>, + /* shared params */ + ) -> (FunctionHeaderT<'s, 't>, ReferenceExpressionTE<'s, 't>) { + match which { + FunctionBodyMacro::LockWeak => self.generate_function_body_lock_weak(coutputs, env, /* ... */), + FunctionBodyMacro::AsSubtype => self.generate_function_body_as_subtype(coutputs, env, /* ... */), + // ... + } + } +} +``` + +Since no one calls the dispatcher yet (env lookup is still panic-stubbed), you can leave the match with `todo!()` arms for macros not yet migrated. Fill in arms as you merge each macro. + +### Order of macro merges + +Start with the simplest (unit-struct / one-method) macros first: + +1. `lock_weak_macro.rs` — two fields, one method. Good first example. +2. `as_subtype_macro.rs` — four fields, one method. +3. `same_instance_macro.rs`, `functor_helper.rs` — small helpers. +4. RSA/SSA macros (10 files) — mostly copy-paste of the same shape. +5. `struct_drop_macro.rs`, `interface_drop_macro.rs` — extends both `IFunctionBodyMacro` and `IOnStructDefinedMacro` / `IOnInterfaceDefinedMacro`; two methods to merge. +6. `struct_constructor_macro.rs` — multiple methods + helper fns. +7. `abstract_body_macro.rs`, `anonymous_interface_macro.rs` — the complex ones, leave for last. + +Commit one macro per commit. Error count should stay at 0 throughout (we're clean right now). + +### Unblocking Step 8 + +Two macros currently hold `ExpressionCompiler` as a field — `as_subtype_macro.rs` and `lock_weak_macro.rs`. Once both are merged (struct deleted → field gone), `ExpressionCompiler` is no longer held anywhere and can be deleted in Step 8. Same chain for other vestigial `*Compiler` structs (ArrayCompiler held by RSA macros, ImplCompiler held by AsSubtypeMacro, etc.). + +## The pattern — how to do one sub-compiler + +For each file `src/typing/.../foo_compiler.rs`: + +### Step A: Understand the shape + +1. Read the file. +2. Identify: + - The main `pub struct FooCompiler<'s, 'ctx, 't>` (usually PhantomData or a few fields). + - The empty `impl FooCompiler<'s, 'ctx, 't> {}` right below it. + - Any `pub trait IFooCompilerDelegate { ... }` — a delegate trait. + - Methods in the file. They come in two shapes: + - **Instance methods**: fns inside a `class FooCompiler { ... }` Scala block. In Rust they may already be wrapped in per-method `impl FooCompiler<'s, 'ctx, 't> { fn xxx(...) {} }` blocks, OR they may be free fns at module level (the slice pipeline is inconsistent). + - **Companion statics**: fns inside an `object FooCompiler { ... }` or `object FooCompilerHelper { ... }` Scala block. In Rust these are always free fns and **stay as free fns** — don't wrap them on `Compiler`. + - Any supporting types (`case class Foo`, `sealed trait Bar`, enums). **Leave these alone.** They're not the compiler struct; they're associated data. + +### Step B: Check call sites + +Before editing, grep for the sub-compiler's name across the whole codebase: + +``` +grep -rn "FooCompiler\|foo_compiler" FrontendRust/src/ +``` + +What you want to know: +- **Rust-level field references** like `pub foo_compiler: FooCompiler<'s, 'ctx, 't>` inside another sub-compiler's struct definition. Those are real Rust and mean the type can't be deleted yet. +- **Rust call sites** like `self.foo_compiler.do_thing(...)`. These are rare at this stage because bodies are panic — but if you find any, you'll need to rewrite them as `self.do_thing(...)` after the merge. +- **Scala-comment references** like `val fooCompiler = new FooCompiler(...)` inside a `/* */` block. These are not Rust and you ignore them. + +### Step C: Pick deletion strategy + +Based on what you find: + +- **If no other Rust code references `FooCompiler<'s, 'ctx, 't>` as a type** (the common case for pure leaf types): **delete the struct entirely.** The markers and Scala block stay. +- **If other sub-compilers still hold `pub foo_compiler: FooCompiler<'s, 'ctx, 't>` fields**: **keep the struct as a `PhantomData` placeholder with a `// vestigial` comment.** It gets deleted in Step 8 cleanup once all holders are gone. +- **If a delegate trait `IFooCompilerDelegate` exists and no Rust code references it outside the file**: delete it, leaving the marker and Scala block. +- **If the delegate trait is referenced by fn parameter types in the file** (like `IInfererDelegate` in `compiler_solver.rs`): **keep it vestigial** — don't delete the trait body until the fn params referencing it are rewritten (which is separate work, not part of this refactor). + +### Step D: Make the edits + +A typical sub-compiler merge touches three regions of the file: + +**1. Add the import.** Near the existing `use` statements add: + +```rust +use crate::typing::compiler::Compiler; +``` + +**2. Reshape the struct/impl region.** Before: + +```rust +// TODO: placeholder PhantomData — replace with real fields during body migration +// mig: struct FooCompiler +pub struct FooCompiler<'s, 'ctx, 't>(pub std::marker::PhantomData<(&'s (), &'ctx (), &'t ())>); +// mig: impl FooCompiler +impl<'s, 'ctx, 't> FooCompiler<'s, 'ctx, 't> {} +/* +class FooCompiler(...) { +*/ +``` + +After, if deleting entirely: + +```rust +// mig: struct FooCompiler +// mig: impl FooCompiler +/* +class FooCompiler(...) { +*/ +``` + +After, if keeping vestigial: + +```rust +// mig: struct FooCompiler +// vestigial: kept until Step 8 cleanup because sub-compilers still hold `foo_compiler: FooCompiler<'s, 'ctx, 't>` fields +pub struct FooCompiler<'s, 'ctx, 't>(pub std::marker::PhantomData<(&'s (), &'ctx (), &'t ())>); +// mig: impl FooCompiler +/* +class FooCompiler(...) { +*/ +``` + +Note we always delete the empty `impl FooCompiler {}` line — it has nothing in it. + +**3. Wrap each instance method.** This is the bulk of the work. + +Before: + +```rust +// mig: fn do_thing +fn do_thing<'s, 't>(&self, x: Foo<'s, 't>) -> Bar<'s, 't> { + panic!("Unimplemented: do_thing"); +} +/* + def doThing(x: Foo): Bar = { + ... scala body ... + } + +*/ +``` + +After: + +```rust +// mig: fn do_thing +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn do_thing(&self, x: Foo<'s, 't>) -> Bar<'s, 't> { + panic!("Unimplemented: do_thing"); + } +/* + def doThing(x: Foo): Bar = { + ... scala body ... + } + +*/ +} +``` + +The signature changes: +- Remove fn-level `<'s, 't>` generics (they come from the impl block now). +- Add `pub` (Scala defaults to public, and callers across files will need access). +- Ensure `&self` is there as the first parameter. If the original was a free fn without `&self`, add it. + +The structural changes: +- Wrap in `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't, { ... }`. +- Indent the fn by 4 spaces (inside the impl). +- **The Scala `/* ... */` block stays *inside* the impl braces, directly after the fn's closing `}`**, with nothing between them (no closing impl brace). +- The outer `}` that closes the impl comes *after* the Scala block. + +**4. Close the last fn's impl.** After the last method's Scala block, add a final closing `}`: + +```rust + } +} +*/ +} <-- this is new +``` + +The triple-closing-braces region always looks weird. The sequence is: `}` (Scala class close) + `*/` (Scala comment close) + `}` (your impl close). + +### Step E: Fix impl-boundary gaps (you will miss these) + +After wrapping each method, the file looks like this: + +```rust +// mig: fn method_a +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn method_a(&self, ...) { panic!(...); } +/* + scala for method_a +*/ + +// mig: fn method_b <-- PROBLEM: method_a's impl is still open! +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn method_b(&self, ...) { panic!(...); } +... +``` + +You need a `}` between the `*/` of method_a and the `// mig: fn method_b`. I got bitten by this a lot. The fix: + +```rust +/* + scala for method_a +*/ +} <-- add this + +// mig: fn method_b +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + ... +``` + +When doing edits via the Edit tool, I found the easiest approach is: include the boundary in the `old_string` of the *next* method's edit, like this: + +``` +// For method_b, use this as old_string: +scala end of method_a +*/ +// mig: fn method_b +fn method_b(...) ... + +// And new_string: +scala end of method_a +*/ +} + +// mig: fn method_b +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn method_b(...) ... +``` + +So each method's edit closes the *previous* impl and opens the current one. Only the very last method needs a trailing `}` added separately. + +### Step F: Verify + +```bash +cargo check --lib --manifest-path FrontendRust/Cargo.toml 2>&1 | tee /tmp/god-struct-refactor.txt +grep -c "^error" /tmp/god-struct-refactor.txt +``` + +Compare against the previous commit's count. **It should be non-increasing.** If it went up: +- Check for missing `}` at impl boundaries (Step E). +- Check for unused-import warnings in the file you edited — those aren't errors, ignore them. +- Check if you accidentally broke someone else's file (very unusual — the refactor is file-local). + +Spot check that call sites are gone: + +```bash +grep -rn "self\.foo_compiler\." FrontendRust/src/typing/ +``` + +Should be **zero matches** after the merge (because no one was calling `self.foo_compiler.xxx` in Rust anyway — those calls were all in Scala comments). + +### Step G: Commit + +One commit per sub-compiler, with an exception for `StructCompiler` and `FunctionCompiler` — merge those with their layer files in one commit each. Sample commit message: + +``` +God-struct refactor: merge ExpressionCompiler onto Compiler. + +Wrap N methods from src/typing/expression/expression_compiler.rs in +per-fn impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> blocks. The struct +. + +Error count: X -> Y. + +Co-Authored-By: Claude Opus 4.7 (1M context) +``` + +## Gotchas + +### 1. The pre-commit hook blocks `/* */` edits + +There's a hook at `.claude/hooks/check-scala-comments` that compares every `/* */` block in Rust files against the original Scala source. It blocks the commit if they drift. This means: + +- **Don't put English prose in a `/* */` block.** If you want a "no scala counterpart — this is Rust scaffolding" note, use a `//` line comment above the impl instead. The master handoff has an example. +- **Don't reformat Scala content.** If a `/* */` has weird indentation or trailing whitespace, leave it. The hook does exact-match comparison (with a few filtering exceptions, see `docs/usage/check-scala-comments-hook.md`). +- **If you split a `/* */` block in two**, both halves must still parse as the original content concatenated. In practice, don't split them. + +The hook fires on Edit/Write before the change lands. If you get a rejection, read the diff in the error message and fix it. + +### 2. "self outside impl" baseline errors are OK + +`cargo check` has ~30 pre-existing errors of the form: + +``` +error: `self` parameter is only allowed in associated functions + --> src/typing/.../some_file.rs:LINE:5 + | +LINE | &self, +``` + +These are the slice pipeline leaving `&self` on free fns that weren't inside any `impl` block. Each sub-compiler merge that includes one of these fns will *fix* one such error (by wrapping the fn in `impl Compiler`). So your error count may *drop* by 1–5 per merge, not just hold steady. + +Do not worry about these errors as "caused by your change" — they existed before. + +### 3. Indent mismatch doesn't matter + +The pipeline-generated fns are at 2-space or 0-space indent. Wrapping them in `impl Compiler { ... }` means they should technically be at 4-space indent (inside the impl). I kept 4-space indent for the fn signature and 8-space for body when rewrapping. Rust doesn't care about whitespace; don't stress about getting every fn perfectly indented. Keep the convention consistent *within a single merge* if possible, but don't redo previous merges to match. + +### 4. Companion object methods stay as free fns + +Scala distinguishes: + +```scala +class FooCompiler(...) { + def instanceMethod(...) = { ... } // becomes a Compiler method +} + +object FooCompiler { + def staticMethod(...) = { ... } // stays a free fn +} +``` + +Both translate to module-level free fns in the slice-pipeline output, but they have different semantic destinations. To tell them apart, look at the Scala comment — everything between `class FooCompiler(...) {` and the `}` that closes it is an instance method; everything between `object FooCompiler {` and its closing `}` is a static. + +### 5. Delegate trait with param-type references = vestigial + +When I deleted `IInfererDelegate` in `compiler_solver.rs`, the build broke because ~10 fn signatures took `delegate: IInfererDelegate<'s, 't>` as a parameter. I reverted the deletion and marked it vestigial. Pattern: + +- **If the delegate trait is only referenced inside the file** (typically just in a struct field that's going away): delete it. +- **If fn parameter types reference the trait**: mark it vestigial, delete in Step 8 cleanup. + +### 6. Method name collisions (watch for later) + +Several sub-compilers have methods named `compile`, `resolve`, etc. When merging multiple sub-compilers, two of them might have `fn compile(...)` with the same signature — that's a compile error. + +**You haven't hit this yet** in the early sub-compilers because stubs have different arg lists (mostly `()`). When you get to the big ones (StructCompiler, FunctionCompiler), rename for clarity: + +- `StructCompiler.compile` → `compile_struct` +- `FunctionCompiler.compile` → `compile_function` +- `StructCompiler.resolve` → `resolve_struct` +- etc. + +Match the convention in the master handoff (Step 7). + +### 7. "One fn per impl block" convention + +Do not batch multiple fns into a single `impl Compiler { ... }` block. Every single fn gets its own impl wrapper so the Scala comment can sit adjacent to it per the audit-trail convention. This makes files look redundant (10 copies of `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't, { ... }`), and that's intentional. + +### 8. Don't touch other files + +A sub-compiler merge should only touch the sub-compiler's file (and maybe the handoff doc). If a merge needs changes in 3+ files, stop and ask — you're probably doing something beyond the refactor scope. + +## Useful commands + +```bash +# Baseline error count +cargo check --lib --manifest-path FrontendRust/Cargo.toml 2>&1 | tee /tmp/god-struct-refactor.txt +grep -c "^error" /tmp/god-struct-refactor.txt + +# Find errors in a specific file +grep "path/to/your_file.rs" /tmp/god-struct-refactor.txt | grep -v warning + +# Check there are no new Compiler method call sites (should be zero) +grep -rn "self\.foo_compiler\."

Don't invent. The master handoff is pretty detailed; most questions are answered there. +- **Scala semantics** (what does this Scala method actually do?): Check `Frontend/TypingPass/src/dev/vale/typing/FooCompiler.scala`. You usually don't need to understand it; bodies are panic!(). +- **Hook rejections** (what's blocking my commit?): Read the error. `docs/usage/check-scala-comments-hook.md` has background. +- **Lifetime errors** when adding `&self`: If `where 's: 't,` on the impl isn't enough, check the master handoff's "If you get stuck" section. + +## Done criterion for each merge + +- `cargo check` error count non-increasing (with the understanding that stubs fixing pre-existing `self outside impl` errors will *decrease* count). +- No `cannot find type FooCompiler` errors (because the type is either kept-vestigial or all call sites are gone). +- No `self.foo_compiler.` call sites in Rust code. +- Struct deleted (or kept vestigial with `// vestigial` comment). +- Delegate trait deleted (or kept vestigial, documented). +- Every method is in its own one-fn `impl Compiler` block with Scala comment inside braces. +- Commit pushed with a message describing what struct/trait treatment you applied. + +## Final advice + +This refactor is boring and mechanical. That's a feature — it lets you do it quickly and correctly. The hardest part is the impl-boundary gaps (Gotcha 1) and not getting confused by the slice-pipeline's inconsistent style (some methods already in `impl FooCompiler` blocks, some free, some 2-indent, some 0-indent). Take one sub-compiler at a time, commit after each, and the whole thing moves forward at a predictable pace. + +Good luck.

One lifetime example inside (line ~219, `env: &'s IEnvironmentT<'s, 't>` on `IFunctionGenerator::generate`) used the then-current assumption that envs lived in `'s`. That was corrected in Slab 4 planning — envs are now `'t`-allocated; the example signature would use `&'t` today. See `TL-HANDOFF.md` overrides, `quest.md` §3.1, and `docs/reasoning/environments-per-denizen-long-term.md`. + +## Who this is for + +You're a junior engineer picking up a medium-scope structural refactor in a Scala→Rust compiler-migration project. This doc gives you the full picture: the goal, the current state, the target state, the theory behind the design, and the step-by-step approach. Read the whole thing before touching code, then keep it open while you work. + +## 90-second project context + +- **Sylvan** is the overall repo. `Frontend/` is a Scala compiler (the original, authoritative source). `FrontendRust/` is a Rust reimplementation being migrated piece-by-piece from Scala. +- The migration uses a **"slice pipeline"** that inserts `// mig:` marker comments above Scala definitions and generates Rust placeholder stubs. The Scala source stays in the file as a commented-out `/* ... */` block above each corresponding Rust stub, so a reviewer can always see the original. **Never touch the `/* ... */` Scala blocks or `// mig:` markers.** A pre-commit hook enforces this. +- We are focused on the **typing pass** (`FrontendRust/src/typing/`). The typing pass does type inference and type checking. +- There is a design doc at `/Volumes/V/Sylvan/quest.md` describing the three-arena lifetime model and god-struct architecture for this pass. **Read the "Status" section at the top, §1 (Arena and Lifetime Model), §2 (The God Struct), and §2.3 (Macros) before starting.** This doc assumes you've read those. +- Most Rust stub bodies are `panic!()` right now. The typing pass's real logic hasn't been ported yet. This refactor is **purely about restructuring the type/fn layout**, not about implementing any logic. + +## Your task in one sentence + +**Collapse the ~20 separate sub-compiler structs (`StructCompiler`, `ArrayCompiler`, `TemplataCompiler`, `FunctionCompiler`, etc., plus `NameTranslator` and helpers like `ConvertHelper`/`LocalHelper`) into a single `Compiler<'s, 'ctx, 't>` god struct, moving all their methods onto it and deleting the delegate traits and layer-split wrappers.** + +## Why this is being done + +Scala's typing pass is organized as a bunch of separate classes — `StructCompiler`, `FunctionCompiler`, `ArrayCompiler`, etc. — each holding references to the others as fields (`StructCompiler(opts, interner, keywords, templataCompiler, inferCompiler, ...)`). They wire up at runtime via mutable constructor closures. That pattern worked in Scala because of GC + flexible mutation, and because Scala's `class X(f: Foo => Bar)` lets you thread arbitrary closures. + +In Rust that pattern is extremely painful: + +- **Circular references** — `StructCompiler` holds a `TemplataCompiler`, `TemplataCompiler` holds a `StructCompiler`. Can't represent cleanly in Rust without `Rc>` or `Weak`, which we're avoiding per the arena-allocation design. +- **Mutation vs. shared borrow** — the slice-pipeline-generated field lists (`pub delegate: Box>`) are type-system overhead that never actually gets used in stub bodies. +- **Delegate-trait plumbing** — there are ~10 `IXxxCompilerDelegate` traits solely to let sub-compilers call into each other. They add nothing structural. +- **Layer splits are vestigial** — `FunctionCompilerMiddleLayer`, `FunctionCompilerSolvingLayer`, `FunctionCompilerClosureOrLightLayer`, `StructCompilerCore`, `StructCompilerGenericArgsLayer` exist because Scala's `FunctionCompiler.scala` was getting too big for one file. In Rust we can organize by `impl Compiler { ... }` blocks across multiple files without the struct split. + +The target architecture, per `quest.md` §2.1–2.4: + +```rust +pub struct Compiler<'s, 'ctx, 't> { + pub scout_arena: &'ctx ScoutArena<'s>, + pub typing_interner: &'ctx TypingInterner<'t>, + pub keywords: &'ctx Keywords<'s>, + pub opts: &'ctx TypingPassOptions<'s>, +} +``` + +Four fields, all shared-borrow context. Deliberately **not** on the god struct: + +- **`global_env`** — Scala builds `globalEnv` as a local inside `Compiler.compile()`, not as a constructor arg. Rust does the same: pass it through as a method parameter on `compile_program` and anything downstream that needs it. +- **`name_translator`** — Scala's `NameTranslator` is a stateless helper (its methods just translate postparser names through the interner). In Rust every `Compiler` method already has `self.scout_arena` and `self.typing_interner`, so the helper adds nothing. Its translate methods move directly onto `impl Compiler` and the struct is deleted. + +Every typing-pass method is an `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> { fn foo(&self, coutputs: &mut CompilerOutputs<'s, 't>, ...) -> ... }`. Mutual recursion works because `&self` is shared-borrow and `&mut coutputs` is re-borrowed at each call level (quest.md §2.2). + +**Why this is worth doing now** — most method bodies are still `panic!()`, so the refactor is almost purely signature manipulation. If we wait until Slab 1+ fills in real logic, every method body ends up routing through the wrong struct and will need to be rewritten twice. Now is the cheapest time. + +## Background: arenas and interning (essential reading) + +Before you touch anything, understand the arena model. The current Rust codebase has a **placeholder `Interner<'s>` type** that is pure vestigial baggage — you will delete it at the end of this refactor (Step 8), once no sub-compiler still references it. Here's why it exists and what replaces it. + +### Scala has `Interner`; Rust has three arenas + +In Scala, every pass shared one `Interner` GC'd HashMap that dedup'd case-class instances. Typical constructor: + +```scala +class FunctionCompiler(opts: TypingPassOptions, interner: Interner, keywords: Keywords, ...) +``` + +In Rust, the `Interner` GC pattern is replaced by **three scoped arenas** — see `quest.md` §1.1: + +| Arena | Lifetime | What it holds | +|---|---|---| +| `ParseArena<'p>` | `'p` | Parser AST, `StrI<'p>`, parse-time coords | +| `ScoutArena<'s>` | `'s` | Post-parser / higher-typing output (`FunctionA<'s>`, `StructA<'s>`, interned names `IRuneS<'s>` / `INameS<'s>` / `IImpreciseNameS<'s>`), **and typing-pass environments** | +| `TypingInterner<'t>` | `'t` | Interned typing-pass types (`INameT`, `IdT`, `KindT`, `ITemplataT`, `PrototypeT`, `SignatureT`, `OverloadSetT`) and typing output AST (`FunctionDefinitionT`, expressions, `HinputsT`) | + +Each arena has its own set of **intern methods** that accept transient "Val" keys, check for existence, and either return the existing canonical reference or promote the Val into arena storage (see `.claude/rules/postparser/IDEPFL-postparser-interning.md` for the full interning discipline). + +Representative methods (may not all exist yet — some are future work): +- `ScoutArena::intern_str(&self, s: &str) -> StrI<'s>` +- `ScoutArena::intern_rune(&self, val: IRuneValS<'s, 'tmp>) -> IRuneS<'s>` +- `ScoutArena::intern_name(&self, val: INameValS<'s>) -> INameS<'s>` +- `ScoutArena::intern_imprecise_name(...)` +- `TypingInterner::intern_kind(&self, val: KindValT<'s, 't>) -> &'t KindT<'s, 't>` +- `TypingInterner::intern_name(&self, val: INameValT<'s, 't>) -> &'t INameT<'s, 't>` +- `TypingInterner::intern_templata(&self, val: ITemplataValT<'s, 't>) -> &'t ITemplataT<'s, 't>` + +These mostly don't exist in the Rust code yet — they'll be built as part of Slab 0 per `quest.md` §12. For this refactor, you just need to know they're coming and plumb `&'ctx ScoutArena<'s>` + `&'ctx TypingInterner<'t>` into method signatures where they're needed. + +### What the typing pass needs access to + +- When a typing-pass method produces a scout-interned value (e.g. it builds a new `IFunctionDeclarationNameS<'s>` from a user-defined function name), it reaches into `self.scout_arena`. +- When it produces a typing-pass-interned value (a new `IdT<'s, 't>`, `KindT<'s, 't>`, `ITemplataT<'s, 't>`), it reaches into `self.typing_interner`. +- Most methods need both, which is why the god struct holds both as fields. + +### Arena-parameter convention (critical invariant) + +Per `quest.md` §1.2 invariant 5: **arena references use a short borrow lifetime (`'ctx`), not the arena's own lifetime**: + +```rust +// CORRECT +pub struct Compiler<'s, 'ctx, 't> { + pub scout_arena: &'ctx ScoutArena<'s>, // short borrow, long-lived arena + pub typing_interner: &'ctx TypingInterner<'t>, // same + ... +} + +// WRONG (don't do this) +pub scout_arena: &'s ScoutArena<'s>, +``` + +The decoupling works because `ScoutArena::alloc(&self, val: T) -> &'s mut T` returns `'s`-lifetimed data from a short `&self` borrow. Callers don't need to hold the arena for all of `'s` just to allocate into it. This same pattern is already followed in `ParseArena` and `ScoutArena` usage in the parser, postparser, and higher-typing passes — you don't need to invent it, just mirror it. + +### Standalone functions + +Not every function is a `Compiler` method. The god struct covers the main pipeline, but some code is genuinely stateless: + +- Scala `object Foo { def bar(...) }` companions — translate to Rust `pub fn bar(...)` at module level. +- Visitor/collector helpers that walk AST and don't need state. +- Generic utilities like `get_compound_type_mutability`. + +For those, **pass `&'ctx ScoutArena<'s>` and `&'ctx TypingInterner<'t>` in as parameters individually**: + +```rust +pub fn translate_generic_function_name<'s, 'ctx, 't>( + scout_arena: &'ctx ScoutArena<'s>, + typing_interner: &'ctx TypingInterner<'t>, + function_name: IFunctionDeclarationNameS<'s>, +) -> &'t IFunctionTemplateNameT<'s, 't> { panic!() } +``` + +**Don't bundle them into a context struct.** We discussed this and decided to keep the two refs as individual params. It makes signatures longer but keeps the type of each param explicit and readable. + +### The `Interner` placeholder + +Right now, `FrontendRust/src/interner.rs` contains this one line: + +```rust +pub struct Interner<'s>(pub std::marker::PhantomData<&'s ()>); +``` + +It was added to satisfy ~70 stale imports across typing-pass files. It has no methods, no fields, and no behavior. **You will delete it in the Step 8 cleanup commit, after every sub-compiler that references it is gone.** Don't delete it earlier — sub-compilers hold `pub interner: &'ctx Interner<'s>` fields, and removing the type before the sub-compilers would break the build for the entire duration of the refactor. When each sub-compiler is merged onto `Compiler`, its method bodies reach through `self.scout_arena` or `self.typing_interner` (both real fields on the god struct) instead of the `interner` field, which disappears with the sub-compiler struct. + +### Keywords and TypingPassOptions + +`Keywords<'s>` is a real type in `FrontendRust/src/keywords.rs` — a cache of pre-interned `StrI<'s>` values for keywords like `self`, `int`, `drop`, etc. Scout-lifetimed, because it's interned into the scout arena and survives through instantiation. It stays as a god-struct field per `quest.md` §9. + +`TypingPassOptions<'s>` is configuration (global options, debug output callback, tree-shaking flag). Also a god-struct field. + +## Current state — inventory + +### Sub-compiler structs to merge (~20) + +These all currently exist as `pub struct FooCompiler<'s, 'ctx, 't> { ... }` (some as PhantomData stubs) with fields like `opts, interner, keywords, *_compiler`. All their methods get moved onto `Compiler<'s, 'ctx, 't>`. The structs themselves get deleted. + +**Leaves (no references to other compilers as fields — easiest first):** +- `VirtualCompiler` — `src/typing/function/virtual_compiler.rs`. Small. +- `LocalHelper` — `src/typing/expression/local_helper.rs`. Small. +- `NameTranslator` — `src/typing/names/name_translator.rs`. Currently `pub struct NameTranslator<'s>(PhantomData)`. ~6 translate methods; delete the struct entirely, move methods onto `impl Compiler`. +- `ConvertHelper` — `src/typing/convert_helper.rs`. Small. Exercises delegate-trait deletion (`IConvertHelperDelegate`). + +**Middle tier (reference only leaf compilers):** +- `DestructorCompiler` — `src/typing/function/destructor_compiler.rs`. +- `SequenceCompiler` — `src/typing/sequence_compiler.rs`. +- `OverloadResolver` — `src/typing/overload_resolver.rs`. +- `InferCompiler` — `src/typing/infer_compiler.rs` (plus the `compiler_solver.rs` module inside it which contains the `advance_infer`/`continue`/`solve`/`sanity_check_conclusion` free fns). + +**Upper tier (reference multiple mid-tier compilers):** +- `PatternCompiler` — `src/typing/expression/pattern_compiler.rs`. +- `CallCompiler` — `src/typing/expression/call_compiler.rs`. +- `BlockCompiler` — `src/typing/expression/block_compiler.rs`. +- `ExpressionCompiler` — `src/typing/expression/expression_compiler.rs`. +- `TemplataCompiler` — `src/typing/templata_compiler.rs`. +- `EdgeCompiler` — `src/typing/edge_compiler.rs`. +- `ImplCompiler` — `src/typing/citizen/impl_compiler.rs`. +- `StructCompiler` — `src/typing/citizen/struct_compiler.rs`. Big. +- `ArrayCompiler` — `src/typing/array_compiler.rs`. Big. +- `BodyCompiler` — `src/typing/function/function_body_compiler.rs`. +- `FunctionCompiler` — `src/typing/function/function_compiler.rs`. Biggest. + +**Vestigial "layer" splits to eliminate entirely:** +- `FunctionCompilerMiddleLayer` — `src/typing/function/function_compiler_middle_layer.rs` +- `FunctionCompilerSolvingLayer` — `src/typing/function/function_compiler_solving_layer.rs` +- `FunctionCompilerClosureOrLightLayer` — `src/typing/function/function_compiler_closure_or_light_layer.rs` +- `FunctionCompilerCore` — `src/typing/function/function_compiler_core.rs` +- `StructCompilerCore` — `src/typing/citizen/struct_compiler_core.rs` +- `StructCompilerGenericArgsLayer` — `src/typing/citizen/struct_compiler_generic_args_layer.rs` + +These are artifacts of Scala's splitting one big file into multiple "layer" files. In Rust they offer nothing — merge all their methods into `impl Compiler` too. The files stay (for the migration audit trail), but the struct definitions are deleted and their methods get the `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't>` wrapper. + +### Delegate traits to delete (~10) + +These all exist solely to let sub-compilers call into each other without holding direct references. Per `quest.md` §2.4 they go away entirely: + +- `IExpressionCompilerDelegate` — `src/typing/expression/expression_compiler.rs:69` +- `IFunctionCompilerDelegate` — `src/typing/function/function_compiler.rs:55` +- `IInfererDelegate` — `src/typing/infer/compiler_solver.rs:102` +- `IStructCompilerDelegate` — `src/typing/citizen/struct_compiler.rs:107` +- `IConvertHelperDelegate` — `src/typing/convert_helper.rs:48` +- `IBlockCompilerDelegate` — `src/typing/expression/block_compiler.rs:44` +- `IBodyCompilerDelegate` — `src/typing/function/function_body_compiler.rs:46` +- `IFunctionGenerator` (trait, not to be confused with the `enum IFunctionGenerator` in quest.md §2.3) — `src/typing/compiler.rs:67` +- Anywhere else you find `pub trait I*Delegate<'s, 't> {}` or `pub trait I*Generator<'s, 't> {}` that looks like a dispatch placeholder. + +Wherever these traits are declared, check for: +1. `Box>` or `&'ctx dyn IFooDelegate<'s, 't>` fields on sub-compiler structs — delete them (the sub-compiler struct is going away anyway, but if you're migrating incrementally, these fields need to go in the first step of merging that sub-compiler). +2. Call sites like `self.delegate.do_thing(...)` — these become `self.do_thing(...)` after the method is merged onto `Compiler`. + +### Macros (~20) — keep the structs, shed the fields + +Per `quest.md` §2.3, macros are a different case: + +```rust +pub enum IFunctionGenerator<'s, 't> { + AsSubtype(AsSubtypeMacro<'s, 't>), + LockWeak(LockWeakMacro<'s, 't>), + StructDrop(StructDropMacro<'s, 't>), + // ... ~20 variants +} + +impl<'s, 't> IFunctionGenerator<'s, 't> { + pub fn generate( + &self, + compiler: &Compiler<'s, '_, 't>, + coutputs: &mut CompilerOutputs<'s, 't>, + env: &'s IEnvironmentT<'s, 't>, + // ... + ) -> &'t FunctionHeaderT<'s, 't> { ... } +} +``` + +So the macro **structs** (`AsSubtypeMacro`, `LockWeakMacro`, `StructDropMacro`, `StructConstructorMacro`, `AbstractBodyMacro`, `AnonymousInterfaceMacro`, `SameInstanceMacro`, `FunctorHelper`, the `RSA*`/`SSA*` macros, `InterfaceDropMacro`) **stay** — they're stored in the global env as variants of the `IFunctionGenerator` enum. But they **shed their fields**: the current `opts, interner, keywords, destructor_compiler, expression_compiler, array_compiler, ...` fields all disappear. `generate()` takes `&Compiler<'s, '_, 't>` + `&mut CompilerOutputs` as parameters and reaches through the god struct for everything it used to access via its own fields. + +**Expected end state of a macro struct:** + +```rust +pub struct StructDropMacro<'s, 't> { + pub _phantom: PhantomData<(&'s (), &'t ())>, // or no fields at all if nothing is needed +} +``` + +Macros are ~20 files in `src/typing/macros/` and its subdirs (`citizen/`, `rsa/`, `ssa/`). Each needs the same treatment: strip fields, update `generate()` signature. + +## What "done" looks like + +After this refactor: + +1. `FrontendRust/src/interner.rs` no longer has `pub struct Interner<'s>(...)`. (The `StrI<'s>` type stays — that's legit, a real arena-backed string wrapper.) +2. No file in `src/typing/` defines a `pub struct FooCompiler<...>` with compiler fields on it. Exception: the god struct `Compiler<'s, 'ctx, 't>` exists in one place (probably `src/typing/compiler.rs`). +3. Every method that was on a sub-compiler is now in an `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> { fn ... }` block, preserved directly above its original `// mig:` marker and `/* ... */` Scala comment. **No code moves relative to its Scala comment.** The `impl Compiler` wrapper replaces the former `impl FooCompiler` wrapper in place. +4. No `IXxxCompilerDelegate` trait exists in `src/typing/`. +5. Macro structs (`AsSubtypeMacro`, etc.) have no fields (or just `_phantom: PhantomData`). Their `generate()` takes `&Compiler<'s, '_, 't>` + `&mut CompilerOutputs<'s, 't>`. +6. `cargo check --lib --manifest-path FrontendRust/Cargo.toml` produces **no E0425 "cannot find type `FooCompiler`"** errors (those types are gone — callers now reach through `self` on `Compiler`). +7. Total error count doesn't go up (much). Error delta should be dominated by: + - **Cascading new-types-missing errors** if you rename a sub-compiler without updating all call sites. These should go to 0 if you're thorough. + - **`ScoutArena`/`TypingInterner` "not yet built" errors** if you try to use intern methods that don't exist yet. Stub those with `panic!()`-bodied placeholder methods on the arena types if needed. + +## Key design rules (must-preserve invariants) + +These come from `quest.md` §11 and the project's `CLAUDE.md`. Violating them will block the refactor or break other work. + +1. **`'s` outlives `'t`.** Every type that transitively holds `&'s` data needs `where 's: 't`. Already declared on existing types; keep it when you redeclare. +2. **No `&mut self` on `Compiler` or any of its methods.** Mutable state is `CompilerOutputs`. If you find a method that needs `&mut self`, something's wrong — figure out what state is supposed to be on `CompilerOutputs` instead. +3. **Arena parameters use short borrow lifetime (`'ctx`), not the arena's own.** `&'ctx ScoutArena<'s>`, never `&'s ScoutArena<'s>`. +4. **Every Rust definition stays directly above its `/* scala */` comment.** No reordering. No movement. The `// mig:` markers pair Rust stubs to Scala definitions; re-arranging them breaks the audit trail. +5. **No `Vec`/`HashMap`/`String`/`Box`/`Rc` inside arena-allocated types** (AASSNCMCX). Not directly relevant to this refactor — you're not adding new arena-allocated types — but don't accidentally violate it when writing placeholders. +6. **Inherent `impl` blocks contain exactly one fn, and the `/* scala */` block lives inside the impl braces, immediately after the fn's closing brace.** This is our established convention — the Scala comment must directly follow its corresponding Rust fn with nothing between them, not even a closing impl brace: + ```rust + // mig: fn resolve_struct + impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> { + pub fn resolve_struct(&self, coutputs: &mut CompilerOutputs<'s, 't>, ...) { panic!() } + /* + def resolveStruct(...) = { ... } + */ + } + ``` + Don't lump multiple methods into one big `impl Compiler { ... }`, and don't move the Scala comment outside the impl braces. +7. **Never edit `/* ... */` Scala comment blocks.** Pre-commit hook will block you. +8. **No inline `/* ... */` block comments in Rust.** Use `//` line comments only. Same hook. +9. **Always pipe `cargo check`/`build`/`test` output into a fixed file in `/tmp`** and never chain `| grep`/`| tail` onto the command. See CLAUDE.md. Example: + ``` + cargo check --lib --manifest-path FrontendRust/Cargo.toml 2>&1 | tee /tmp/god-struct-refactor.txt + ``` + Then separately: + ``` + grep -c "^error" /tmp/god-struct-refactor.txt + ``` + +## Approach — leaf-first, one sub-compiler at a time + +**Do not do this all at once.** You will deadlock on cross-file type errors. Follow the order below. After each sub-compiler, commit, verify the build state, continue. + +### Step 0: Preparation (one-time, single prep commit) + +The goal of this step is to get `Compiler` and `TypingInterner` into a shape where every sub-compiler merge can be done without breaking the build. **Leave `Interner<'s>` in place for now** — it's the vestigial placeholder currently held as `pub interner: &'ctx Interner<'s>` on every sub-compiler. If you delete it on day 1, every sub-compiler stops compiling until its merge commit lands, which can be weeks. Delete it in the final cleanup commit instead, once all sub-compilers that referenced it are gone. + +1. **Create `TypingInterner<'t>`** (e.g. in `src/typing/typing_interner.rs`). Real struct, not just PhantomData. Stub the six intern methods with `panic!()` bodies so Compiler methods can reference them during merges: + ```rust + pub struct TypingInterner<'t> { /* real fields as needed, or PhantomData */ } + + impl<'t> TypingInterner<'t> { + pub fn intern_name<'s>(&self, val: INameValT<'s, 't>) -> &'t INameT<'s, 't> { panic!("intern_name not yet implemented") } + pub fn intern_kind<'s>(&self, val: KindValT<'s, 't>) -> &'t KindT<'s, 't> { panic!("intern_kind not yet implemented") } + pub fn intern_id<'s, T: Copy>(&self, val: IdValT<'s, 't, T>) -> &'t IdT<'s, 't, T> { panic!("intern_id not yet implemented") } + pub fn intern_templata<'s>(&self, val: ITemplataValT<'s, 't>) -> &'t ITemplataT<'s, 't> { panic!("intern_templata not yet implemented") } + pub fn intern_prototype<'s>(&self, val: PrototypeValT<'s, 't>) -> &'t PrototypeT<'s, 't> { panic!("intern_prototype not yet implemented") } + pub fn intern_signature<'s>(&self, val: SignatureValT<'s, 't>) -> &'t SignatureT<'s, 't> { panic!("intern_signature not yet implemented") } + } + ``` + The `*ValT` enums don't exist yet (they're Slab 2–3 work). If that makes the stubs unbuildable, either define the `*ValT` enums as empty placeholder enums (`pub enum INameValT<'s, 't> {}`) or weaken the stubs to take `()` — either is fine. + +2. **Fill in the god struct** in `src/typing/compiler.rs`. Replace the current PhantomData stub with four fields per quest.md §2.1: + ```rust + pub struct Compiler<'s, 'ctx, 't> { + pub scout_arena: &'ctx ScoutArena<'s>, + pub typing_interner: &'ctx TypingInterner<'t>, + pub keywords: &'ctx Keywords<'s>, + pub opts: &'ctx TypingPassOptions<'s>, + } + ``` + `ScoutArena<'s>` already exists at `src/scout_arena.rs`. `Keywords<'s>` at `src/keywords.rs`. `TypingPassOptions<'s>` at `src/typing/compilation.rs`. All four are real — no placeholders needed. + +3. **Do NOT delete `Interner<'s>` yet.** Sub-compilers still reference it. Deletion happens in Step 8 cleanup (alongside `NameTranslator<'s>`, which is kept for the same reason during Step 3). + +4. Get a baseline: + ``` + cargo check --lib --manifest-path FrontendRust/Cargo.toml 2>&1 | tee /tmp/god-struct-refactor.txt + grep -c "^error" /tmp/god-struct-refactor.txt + ``` + Write the number down. Build should be **green or close to green** after this commit (we're only adding things). Each subsequent sub-compiler merge commit should keep the error count non-increasing. + +### Step 1: Merge leaf sub-compiler `VirtualCompiler` + +Pick `VirtualCompiler` first. Why: it's small, a pure leaf (holds no references to other compilers), and has no delegate trait. It's the cleanest demonstration of the pattern — the struct disappears entirely and its methods move onto `impl Compiler`. Use it as your template for the other leaves. + +Workflow: + +**a. Read the file.** `src/typing/function/virtual_compiler.rs`. Note: the struct definition, each method, and its `// mig:`/`/* scala */` pairs. + +**b. Delete the struct.** Remove the `pub struct VirtualCompiler<'s, 'ctx, 't> { ... }` block. Preserve the `// mig: struct VirtualCompiler` marker and the `/* ... */` Scala block above it. + +**c. Rewrap each method.** For each `fn xxx(...)` in the file: + - Take it out of the `impl VirtualCompiler<'s, 'ctx, 't>` block and put it into a per-fn `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> { ... }` block in place. + - The first parameter was already `&self` — semantics change (now a method on `Compiler`, not `VirtualCompiler`), but syntax is identical. + - Body stays `panic!()` — we're not implementing logic here. + - Keep the `// mig:` marker directly above the `impl Compiler { ... }` line. + - **Keep the `/* scala */` block immediately below the fn's closing `}`, inside the impl braces.** Nothing between the fn and the Scala comment, not even a closing impl brace. The impl's own closing `}` goes after the Scala comment. See the example in Key Design Rules §6. + +**d. Delete the `impl VirtualCompiler` wrapper.** Once all methods are rewrapped, the outer `impl VirtualCompiler<'s, 'ctx, 't> { ... }` block is empty — remove it. + +**e. Update call sites.** Find every call: + ``` + grep -rn "virtual_compiler\." FrontendRust/src/typing/ + grep -rn "VirtualCompiler\." FrontendRust/src/typing/ + ``` + Change `self.virtual_compiler.foo(...)` to `self.foo(...)` everywhere. Same for any `self.delegate` field on callers that used to hold a `VirtualCompiler` reference (drop the field, the call becomes direct). + +**f. Verify.** Run cargo check. Error count should go down. `cannot find type VirtualCompiler` errors should be 0. + +**g. Commit.** Commit message template: + ``` + Merge VirtualCompiler methods onto Compiler god struct. + + Move from impl VirtualCompiler onto + impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't>. Each method keeps its // mig: + marker and /* scala */ block intact; wrapper impl block is per-fn per + project convention. Delete the struct and the surrounding impl block. + + Update ~N call sites that used self.virtual_compiler.foo() to self.foo(). + + Error count: -> . + ``` + +### Step 2: Merge leaf `LocalHelper` + +Same workflow, `src/typing/expression/local_helper.rs`. Small. Deletes the struct, moves methods onto `Compiler`, updates call sites. + +### Step 3: Merge leaf `NameTranslator` + +Same workflow, `src/typing/names/name_translator.rs`. ~9 `translate_*` methods. The methods move onto `impl Compiler`; the struct adds nothing in Rust once its methods are on `Compiler`. + +**But keep `pub struct NameTranslator<'s>(PhantomData<&'s ()>)` in place for now** — same reasoning as `Interner<'s>` in Step 0. ~9 sub-compilers and macros hold `pub name_translator: NameTranslator<'s>` fields; deleting the type here would break their build until each is merged. The struct is a vestigial placeholder until Step 8 cleanup, which deletes both `Interner<'s>` and `NameTranslator<'s>` once every sub-compiler that referenced them is gone. + +Update call sites: `self.name_translator.translate_struct_name(foo)` → `self.translate_struct_name(foo)`. (Anywhere that actually calls a translate method in Rust today — most call sites are inside Scala `/* */` blocks and don't need touching.) + +### Step 4: Merge leaf `ConvertHelper` + +Same workflow. Note: `ConvertHelper` has a `delegate: Box>` field currently. Drop the field, delete the `IConvertHelperDelegate` trait, and rewrite any `self.delegate.foo(...)` call sites as direct `self.foo(...)`. + +### Step 5: Work upward through the tiers + +Order (mid-tier): +- `DestructorCompiler` +- `SequenceCompiler` +- `OverloadResolver` +- `InferCompiler` (and its `compiler_solver.rs` free fns `advance_infer`, `continue`, `solve`, `sanity_check_conclusion`, `complex_solve`, `solve_receives`, `narrow`, `solve_rule`, `solve_call_rule`, `literal_to_templata`) + +Order (upper-tier): +- `PatternCompiler` +- `CallCompiler` +- `BlockCompiler` +- `ExpressionCompiler` +- `TemplataCompiler` +- `EdgeCompiler` +- `ImplCompiler` +- `StructCompiler` +- `ArrayCompiler` +- `BodyCompiler` +- `FunctionCompiler` (do this last — it's the largest, and other sub-compilers reference it) + +Eliminate the `*Layer` splits as you go, **in one big commit per owning sub-compiler**: +- When you reach `FunctionCompiler`, all of `FunctionCompilerMiddleLayer`, `FunctionCompilerSolvingLayer`, `FunctionCompilerClosureOrLightLayer`, `FunctionCompilerCore` get merged in the **same** commit. Their methods all go onto `impl Compiler`. +- When you reach `StructCompiler`, merge `StructCompilerCore` and `StructCompilerGenericArgsLayer` in one commit with `StructCompiler`. + +Rationale for one-big-move on layer splits: the layers aren't independently meaningful in Rust; splitting them across commits just creates intermediate states where half the methods of a conceptual unit live on `Compiler` and half don't. Merge the whole unit at once. + +### Step 6: Handle macros + +Per `quest.md` §2.3. For each macro struct in `src/typing/macros/**`: + +1. Strip its fields (`opts`, `interner`, `keywords`, and any `*_compiler: FooCompiler` refs). Replace with `_phantom: PhantomData<(&'s (), &'t ())>` or empty struct. +2. Rewrite `generate_function_body` (and any other methods) to take `&Compiler<'s, '_, 't>` as a param, and access things through it (`compiler.scout_arena`, `compiler.typing_interner`, `compiler.opts`, `compiler.keywords`, etc.). +3. Update the `IFunctionGenerator` enum (if it exists yet — probably not, may need to define it per quest.md §2.3) in `src/typing/compiler.rs` to have a variant per macro. + +You can do this after the sub-compiler merge is complete, or interleaved — whichever is less confusing. I'd lean "after", because during the sub-compiler merge you probably don't have stable arena methods yet. + +### Step 7: Method name collisions + +While merging, you'll hit collisions. Scala had methods on separate classes with the same name. Rules: + +- Prefix with the original sub-compiler name, snake_cased: `StructCompiler.compile` → `compile_struct`, `InterfaceCompiler.compile` → `compile_interface`, `StructCompiler.resolve` → `resolve_struct`. +- When the original method name is already unambiguous (e.g. `evaluate_templated_function_from_call_for_prototype`), leave it alone. +- When two sub-compilers both have a same-named method and the meaning is "compile the thing this sub-compiler is about", prefix with what the thing is: `compile_struct`, `compile_function`, `compile_interface`, `compile_impl`, `compile_static_sized_array`, etc. + +Keep the `// mig:` marker matching whatever name you picked. + +### Step 8: Final cleanup + +After all sub-compilers and macros are merged: + +1. **Delete `pub struct Interner<'s>(...)` from `src/interner.rs`.** By this point, every sub-compiler that referenced it is gone, so there should be no more `&'ctx Interner<'s>` fields anywhere. Leave `pub struct StrI<'s>` — that's real. Leave `InternedSlice<'a, T>` — also real. +2. **Delete `pub struct NameTranslator<'s>(...)` from `src/typing/names/name_translator.rs`.** Same reasoning as `Interner<'s>` — the struct was kept as a vestigial placeholder during Step 3 to avoid breaking sub-compilers that held `pub name_translator: NameTranslator<'s>` fields. Once every sub-compiler is merged, no such fields remain, and the struct can be removed. Leave the `// mig: struct NameTranslator` marker and the Scala `class NameTranslator(...)` block. +3. Remove the dead `use crate::interner::Interner;` imports across the typing pass. +4. Remove the dead `use crate::typing::*compiler::*` imports that referenced the deleted sub-compilers. +5. Audit the `src/typing/mod.rs` — are there `pub mod foo_compiler;` entries for files that now only exist as `impl Compiler` wrappers? Those `mod` entries still need to exist (the files are still there), but may no longer be needed as `pub mod` if they don't export anything externally. +6. Delete the delegate traits (`IExpressionCompilerDelegate`, etc.) — by this point they should have zero uses. +7. Search for any `Box` or `&dyn I*Delegate` that are leftover and fix. +8. One final `cargo check`. Note the error count. Commit as a cleanup pass. + +## Gotchas & watch-outs + +### Slice-pipeline quirks you'll hit + +- **Same-named `pub mod` and `pub struct`.** In this session we found `pub mod StructCompiler` (a translation of Scala's `object StructCompiler` companion) colliding with `pub struct StructCompiler`. Renamed to `pub mod struct_compiler_module`. Look for this pattern on other sub-compilers — Scala's `object Foo` companions may have been transliterated as `pub mod Foo` where `pub struct Foo` also exists. Rename the module, don't rename the struct. +- **Free fns with `&self` but not inside any impl block.** The slice pipeline sometimes writes `fn foo(&self, ...) { panic!() }` at module level. Invalid Rust. Wrap in an `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> { ... }` block when you migrate — that's what this refactor fixes structurally anyway. +- **`T: KindT` / `T: IFunctionNameT` trait bounds on enums.** You'll find generic params like `>` where `KindT` is an enum, not a trait. Drop the bound (change to ``). This was cleared out in a prior session, but new ones may appear during the merge if you touch generic method signatures. +- **Bare `RegionT<'s, 't>` vs `RegionT`.** `RegionT` is currently a zero-field struct with no lifetime params, even though it's Scala-parity would suggest otherwise. Don't add `<'s, 't>` to it unless you also make it generic. If a stub has `RegionT<'s, 't>` in a signature, that's wrong — change to bare `RegionT`. + +### Movement invariant + +**No Rust code moves relative to its `/* scala */` comment.** Ever. Even when merging compilers, each method stays in the file it was in, directly above its Scala comment. You're only: +- Rewriting the surrounding `impl FooCompiler { ... }` block into `impl Compiler { ... }`. +- Renaming the method (if needed). +- Changing the first parameter from `&self` (on FooCompiler) to `&self` (on Compiler) — same syntax, different semantics. + +If you find yourself moving a method from file A to file B, stop. That's not part of this refactor. Rust allows arbitrarily many `impl Compiler { ... }` blocks in arbitrarily many files. Leave things where they are. + +### Interner reference cleanup + +When you strip `pub interner: &'ctx Interner<'s>` from a sub-compiler, decide based on what the methods do: + +- Methods that intern scout-lifetime values → replace with `scout_arena: &'ctx ScoutArena<'s>` (via `self.scout_arena` once on the god struct). +- Methods that intern typing-pass values → replace with `typing_interner: &'ctx TypingInterner<'t>`. +- Methods that don't intern anything → drop the field entirely. + +**If you're not sure**, look at the Scala comment below the method. If it calls `interner.intern(SomeTypingName(...))`, it's a typing-pass interner. If it calls `interner.intern(SomeScoutName(...))` or builds a name from `StrI`/`RuneS`/etc., it's scout. If it just passes `interner` through to a helper, trace the helper and see what the helper interns. + +When in doubt, include both on the god struct (which is the plan anyway) and route through `self.scout_arena` / `self.typing_interner` in the method body. + +### Placeholder arena methods + +You may need to stub arena methods that don't exist yet. Example: if a method body panics but its signature references `self.scout_arena.intern_name(...)`, rustc will complain the method doesn't exist. Fix: add a stub on `ScoutArena`: + +```rust +impl<'s> ScoutArena<'s> { + pub fn intern_name<'tmp>(&self, val: INameValS<'s, 'tmp>) -> INameS<'s> { + panic!("intern_name not yet implemented") + } +} +``` + +This is fine — it's consistent with how the rest of the typing pass is stubbed. Slab 0 will replace the panic with real logic. + +### Don't run tasks in the background + +Per project CLAUDE.md: "Please don't run tasks in the background." Run `cargo check` in the foreground. Don't use `run_in_background: true`. If you have a long-running build, just wait for it. + +### Don't use sed + +Per project CLAUDE.md "Bulk Sed Safety Protocol." Manual edits via the Edit tool only. Don't batch-rewrite with sed. + +## How to verify at each step + +After each sub-compiler merge: + +1. `cargo check --lib --manifest-path FrontendRust/Cargo.toml 2>&1 | tee /tmp/god-struct-refactor.txt` +2. `grep -c "^error" /tmp/god-struct-refactor.txt` — should be non-increasing vs. previous commit (+/- small fluctuations as hidden errors get revealed). +3. `grep -c "cannot find type \`FooCompiler\`" /tmp/god-struct-refactor.txt` — should be 0 for the sub-compiler you just merged. +4. `grep "self.name_translator\." FrontendRust/src/typing/` — should be 0 hits after merging NameTranslator. Same pattern for each sub-compiler. +5. `git diff --stat` — should touch a bounded set of files per merge. If one merge touches > 20 files you're probably doing too much at once. + +## If you get stuck + +- **Rustc is angry about lifetime elision.** Usually means you added `&self` but the method body reaches into `self.scout_arena.something(...)` and rustc can't figure out the returned reference's lifetime. Try explicitly annotating: `fn foo(&self) -> &'t SomeT<'s, 't>` or `fn foo<'a>(&'a self) -> SomeT<'s, 't>` depending on what needs to outlive what. +- **"Method X is defined multiple times on Compiler."** Collision between two sub-compilers that had same-named methods. Rename one with a sub-compiler prefix (see Step 6 above). +- **"Cannot borrow `self` as mutable because it's also borrowed as immutable."** You're probably inside a method that takes `&self` on `Compiler` and trying to mutate something through `self`. Don't. Route the mutation through `&mut coutputs` or rethink the method — quest.md §2.2 relies on Compiler being immutable. +- **Some method has logic that actually calls into a sub-compiler's `&mut self` method.** Probably shouldn't happen (stubs are all `panic!()`), but if it does, look at the Scala. Scala's sub-compilers didn't mutate themselves either — they all mutated `coutputs` (the Scala equivalent of `CompilerOutputs`). Your method should also be `&self` + `&mut coutputs`. +- **You find a case the design doesn't cover.** Write down the case, skip it, and raise it as a question. Don't invent a solution — ask the senior first. + +## Files & references + +- `/Volumes/V/Sylvan/quest.md` — design doc. §1 arenas, §2 god struct, §3 envs, §11 invariants, §12 slab plan. +- `/Volumes/V/Sylvan/FrontendRust/docs/migration/handoff-typing-imports.md` — earlier handoff covering `use` statements; same style, same project conventions. +- `/Volumes/V/Sylvan/FrontendRust/src/typing/` — your working directory. +- `/Volumes/V/Sylvan/Frontend/TypingPass/src/dev/vale/typing/` — the Scala source, for reference.

No `global_env`, no `name_translator` — see intro. +2. **`TypingInterner<'t>` is created in the Step 0 prep commit** as a real struct with six panic-bodied intern methods (`intern_name`, `intern_kind`, `intern_id`, `intern_templata`, `intern_prototype`, `intern_signature`). Not PhantomData — we want signatures that reference it to have something real to call. +3. **`Interner<'s>` stays in place until Step 8** so sub-compilers remain buildable during merges. +4. **Merge order:** leaves first (`VirtualCompiler` → `LocalHelper` → `NameTranslator` → `ConvertHelper`), then mid-tier, then upper-tier. `FunctionCompiler`+layers and `StructCompiler`+layers are one commit each. + +## Questions for the senior before starting + +1. **The macros' `IFunctionGenerator` enum** — does it exist yet? If not, should you define it during this refactor or defer to Slab 5? +2. **Method naming collisions** — when in doubt, prefix. But which prefix style is preferred? I suggested `compile_struct`, `resolve_struct`, but some codebases use `struct_compile`, `struct_resolve`. Mirror whatever convention you find elsewhere in `typing/`. + +## Final advice + +This is a medium refactor. Pacing: +- **Each sub-compiler takes ~1–3 hours** depending on size (leaves like `VirtualCompiler`/`LocalHelper`/`NameTranslator` fast; `FunctionCompiler` slow). +- **~20 sub-compilers + ~20 macros = ~4–6 focused sessions** to complete. +- **Commit per sub-compiler**, except for `FunctionCompiler`+layers and `StructCompiler`+layers which are one commit each. Don't accumulate unfinished merges across sessions. +- **Build after every commit.** Keep the error count visible and trending down. +- **Don't improvise.** The design in quest.md is detailed; follow it literally. If something is unclear, ask. + +Good luck.

Budget ~3 hours focused. After Slab 10, Slabs 11-13 each target one sub-compiler layer (expression, solver, function/macros) on the same pattern. + +**Read these first in this order**, then come back: + +1. `FrontendRust/docs/migration/handoff-slab-9.md` — the prior signature-rewrite slab on the same file (`templata_compiler.rs`). The translation-rules table, receiver classification, Gotcha set (drop-`interner`/`keywords`, trait-param handling, `&'t IInDenizenEnvironmentT`, `&mut CompilerOutputs` conservative default, closure params) apply verbatim. Slab 10 reuses 100% of the Slab-9 pattern with no new design decisions. +2. `FrontendRust/docs/migration/handoff-slab-8.md` — the foundational signature-rewrite slab. The signature translation table is the canonical reference. +3. `TL-HANDOFF.md` at repo root — file-layout standards ("one fn per impl block, multi-line body") + the current slab roadmap. +4. `FrontendRust/src/typing/templata_compiler.rs` lines 101–1437 — the **49 already-lifted `impl Compiler` blocks** (14 class-methods from prior work + 35 object-methods from Slab 9). These are your style template. +5. This doc. + +You shouldn't need to read the Scala source externally — every Scala `def` sig is already embedded inline in the `/* def ... */` blocks beneath each Rust stub. Those blocks are authoritative. + +--- + +## The big picture: why Slab 10 exists + +After Slab 9, `templata_compiler.rs` is mostly migrated — but the 14 bare `pub fn foo(&self) { panic!(...) }` stubs at the tail (the `class TemplataCompiler` instance methods) remain. Their param lists are lost entirely; each is just `(&self)` with no other params, no return type. + +Similarly, `compiler.rs` has 8 class methods with `()`-placeholder params and 5 object orphan static fns with `()`-placeholders (`print`, `consecutive`, `is_primitive`, `get_mutabilities`, `get_mutability`). These are the `object Compiler { ... }` utilities. + +Finally, `local_helper.rs` and `struct_compiler.rs` each have a tail `object Foo { ... }` block with 2 and 2 free-fn stubs respectively. Some of these already have typed params (e.g. `determine_if_local_is_addressible`'s params are already `&ITemplataT<'s, 't>` and `&LocalS<'s>`); they just haven't been lifted onto `impl Compiler` yet. Slab 10 lifts them uniformly. + +The work is all the same shape as Slab 9: + +1. Read the Scala `/* def ... */` block beneath each stub. +2. Translate each parameter/return per the Slab 8/9 rules table. +3. Drop `interner` / `keywords` params wherever Scala passes them (Rust accesses via `self.typing_interner` / `self.keywords`). +4. Wrap in a one-fn `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't { pub fn ... (&self, ...) -> ... { panic!("..."); } }` block. +5. Leave the Scala `/* */` block unchanged. + +No new design decisions. No new lifetime tricks. No trait definitions needed beyond what Slab 9 already encountered. If you hit something surprising, reread the Slab 9 Gotcha list first — the answer is almost always there. + +By the end of Slab 10: + +- `cargo check --lib` passes with 0 errors, 0 warnings. +- All 30 stubs described below have real `(&self, ...)` signatures inside one-fn `impl` blocks. Bodies stay `panic!("Unimplemented: Slab 14 — body migration");`. (Note: Slab 8/9 used the message `"Unimplemented: Slab 10 — body migration"` — that text is stale per TL-HANDOFF; new panic messages use `Slab 14`. Don't re-touch the ~89 stale messages already in the codebase; only new ones.) +- Scala `/* */` blocks unchanged byte-for-byte. +- Only the 4 files listed below touched. No imports added except what the new signatures require. + +**What Slab 10 is NOT:** + +- No body migration. Bodies stay `panic!()`. Slab 14+. +- No `IBoundArgumentsSource` refactor. Keep `&'t dyn IBoundArgumentsSource<'s, 't>` where Scala's `IBoundArgumentsSource` appears (Slab 9 Gotcha 3). +- No `IPlaceholderSubstituter` trait definition. None of the 30 Slab-10 stubs need that return type (the three `get_placeholder_substituter*` methods that do were already lifted in Slab 9). If a Slab-10 stub's Scala body *calls* `TemplataCompiler.getPlaceholderSubstituter`, that's a body concern — Slab 14+ territory. +- No filling `UseBoundsFromContainer` unit struct fields. +- No `ICompileErrorT` variant filling. +- No touching of the 35 Slab-9-lifted blocks at `templata_compiler.rs` lines 101–1037 or the 14 prior-work-lifted blocks at lines 1034–1437. +- No touching of Slab 8's 54 `CompilerOutputs` impl blocks. +- No `expression_compiler.rs` / `infer_compiler.rs` / `overload_resolver.rs` / etc. — Slabs 11–13. +- No touching the `IFunctionGenerator::generate` trait method at `compiler.rs:57` — it's a trait method, not a `Compiler` method.

The builder-freeze pattern splits mutation from reading: + +- **Mutation** happens in a stack-local `NodeEnvironmentBuilder<'s, 't>` / `FunctionEnvironmentBuilder<'s, 't>` (both defined in `src/typing/env/function_environment_t.rs` at lines 1181 and 1220 respectively). +- `build_in(interner)` freezes the builder into a `&'t NodeEnvironmentT<'s, 't>` / `&'t FunctionEnvironmentT<'s, 't>`. + +**Signature translation:** + +- `nenv: NodeEnvironmentBox` → `nenv: &mut NodeEnvironmentBuilder<'s, 't>` (default — most Scala uses mutate) +- `nenv: NodeEnvironmentT` or `startingNenv: NodeEnvironmentT` (the read-only snapshot) → `nenv: &'t NodeEnvironmentT<'s, 't>` +- `parentFate: FunctionEnvironmentBoxT` → `parent_fate: &mut FunctionEnvironmentBuilder<'s, 't>` + +**Conservative default**: if unsure whether the Scala body mutates, use `&mut NodeEnvironmentBuilder`. This matches Slab 9 Gotcha 8 ("when in doubt, `&mut`"). + +**Return type note**: methods that return a fresh `NodeEnvironmentBox` (e.g. `makeChildNodeEnvironment`) — if you see any in the Slab-11 stub returns, translate as `NodeEnvironmentBuilder<'s, 't>` by value (owned, stack-local, caller freezes with `.build_in(...)`). None of the 39 targets appear to return a box type in their `/* */` signatures, but double-check each. + +### Gotcha 2: `evaluateBlockStatements` appears twice — don't unify + +`evaluate_block_statements` exists at: +- `expression_compiler.rs:1970` (Scala's `ExpressionCompiler.evaluateBlockStatements`) +- `block_compiler.rs:103` (Scala's `BlockCompiler.evaluateBlockStatements` — **already renamed in Rust to `evaluate_block_statements_block`** to avoid collision) + +Both get lifted separately. Don't try to unify them. Preserve the `_block` suffix on the block_compiler one — it's a prior-work god-struct-collision rename (same spirit as Slab 10's `struct_compiler_get_mutability`). + +### Gotcha 3: `ExpressionT` (the Scala trait return type) → `ExpressionTE<'s, 't>` by value + +Scala's `evaluateLookupForLoad` returns `Option[ExpressionT]`. `ExpressionT` is the Scala trait; Rust's equivalent is the 2-variant `ExpressionTE<'s, 't>` wrapper enum from Slab 5 (§7.1 naming carve-out). It's Copy? No — Slab 5 Gotcha 2 says expression derives drop `Eq/Hash` because of `f64`, but they remain `PartialEq, Debug`. The wrapper enums are 2-variant holding `&'t` refs, so they're effectively Copy-sized but **check** whether `ExpressionTE` derives Copy before passing by value. If not, pass by value anyway (the compiler will tell you if it needs Clone) — `ExpressionTE` is small enough that Copy should be fine to add, but **don't add Copy in Slab 11**. If it doesn't compile, pass `&'t ExpressionTE<'s, 't>` by reference. + +Practical Slab-11 recommendation: **try `Option>` first; fall back to `Option<&'t ExpressionTE<'s, 't>>` if the compiler rejects**. + +### Gotcha 4: `BlockTE` return from `evaluateBlock` — probably `&'t BlockTE<'s, 't>` + +`BlockTE` is an expression AST node (Slab 5). Returns by arena ref: `&'t BlockTE<'s, 't>`. Grep if unsure: + +``` +Grep pattern: "pub struct BlockTE" +``` + +Should land in `src/typing/ast/expressions.rs`. It's Copy-excluded per Slab 5 derive deviation. Return by `&'t`. + +### Gotcha 5: closure params use `impl FnOnce`, not `Fn` / `FnMut` + +Several Slab-11 Scala signatures carry closure params: + +- `afterPatternsSuccessContinuation: (CompilerOutputs, NodeEnvironmentBox, Vector[ILocalVariableT]) => ReferenceExpressionTE` (in `translatePatternList`, `iterateTranslateListAndMaybeContinue`, and several destructure-and-continue methods). +- Various `continuation: ... => ReferenceExpressionTE` closures in the pattern-compiler iterate/destructure family. + +**Translation**: `impl FnOnce() -> `. + +**Why `FnOnce`, not `Fn` / `FnMut`**: Rust closures that capture `&mut CompilerOutputs` or `&mut NodeEnvironmentBuilder` through their enclosing scope can't be `Fn` (immutable call) or readily `FnMut` (mutable call with captured `&mut` in the environment). `FnOnce` sidesteps the re-borrow issue — the closure is consumed after one call, which matches how continuations actually work in the Scala bodies (called exactly once after successful pattern translation). + +Slab 9 Gotcha 6 used `impl Fn(IRuneS<'s>) -> bool` because the closure captured nothing mutable. Slab 11 closures capture nontrivial mutable state, so `FnOnce` is the right default. + +**Exception**: if the body clearly calls the closure multiple times (rare — check the Scala body), use `impl FnMut(...)`. Check inside the `/* */` block. + +**Don't use `Box` or `&dyn FnOnce`** — `impl FnOnce` is cheaper and idiomatic. + +### Gotcha 6: tuple returns stay tuples, not named structs + +Several Slab-11 methods return tuples like `(BlockTE, Set[IVarNameT], Set[IVarNameT], Set[CoordT])` or `(ReferenceExpressionTE, Set[CoordT])`. **Keep as Rust tuples**: + +```rust +) -> (&'t BlockTE<'s, 't>, HashSet>, HashSet>, HashSet>) +``` + +**Don't** promote to a named struct — that's a Rust-idiomatic refactor, not Scala parity. Scala code uses positional destructure (`val (block2, unstackified, restackified, returns) = evaluateBlock(...)`); Rust does the same with tuple destructure. + +If a tuple return gets awkwardly wide (>4 fields), flag it in the handback but don't refactor. + +### Gotcha 7: `ILocalVariableT<'s, 't>` — by value, not by ref + +Per Slab 4, `ILocalVariableT<'s, 't>` is an inline wrapper enum whose variants hold `&'t` refs to concrete variable structs. The wrapper itself is small (tag + pointer) and should be Copy. + +**Verify**: grep `pub enum ILocalVariableT` at `src/typing/env/function_environment_t.rs` and check for `#[derive(Copy, Clone, ...)]`. + +Translation: +- `ILocalVariableT` (param or return) → `ILocalVariableT<'s, 't>` by value +- `Vector[ILocalVariableT]` (slice) → `&[ILocalVariableT<'s, 't>]` + +If the wrapper isn't Copy for some reason, fall back to `&'t ILocalVariableT<'s, 't>`. + +### Gotcha 8: `LocationInFunctionEnvironmentT` — by value with the AASSNCMCX deviation + +Per TL-HANDOFF "Known residual items": `LocationInFunctionEnvironmentT.path: Vec` violates AASSNCMCX (heap `Vec` inside an `'t`-arena-allocated conceptual type) and is flagged for future cleanup. Don't fix in Slab 11 — pass `LocationInFunctionEnvironmentT<'s>` by value. The Vec makes it non-Copy; you may need `.clone()` at body-migration time but for signatures this doesn't matter. + +If passing by value causes a lifetime issue, fall back to `&LocationInFunctionEnvironmentT<'s>` (no `'t` — the inner Vec is heap, not arena). + +### Gotcha 9: `IRulexSR` and `AtomSP` are scout-side `'s`, not typing `'t` + +Scout-pass types (`IRulexSR`, `IRuneS`, `IImpreciseNameS`, `AtomSP`, `BlockSE`, `IExpressionSE`, `LocalS`, `GenericParameterS`, `CitizenAttributeS`, etc.) all carry `<'s>`, not `<'s, 't>`. When passed by reference, they borrow from the scout arena `'s`: + +- `&'s AtomSP<'s>` (single pattern) +- `&[&'s AtomSP<'s>]` (slice of patterns) +- `&'s IRulexSR<'s>` (single rule) +- `&[&'s IRulexSR<'s>]` (slice of rules) +- `&'s BlockSE<'s>` (block scout node) +- `&'s IExpressionSE<'s>` (expression scout node) + +Don't accidentally write `AtomSP<'s, 't>` — that's a compile error. Always single-lifetime `'s`. + +### Gotcha 10: `check_types` method on `call_compiler.rs` — don't confuse with a Rust trait impl + +Rust has the convention that `impl Foo for Bar` provides `bar.check_types(...)` via trait dispatch. Slab-11's `check_types` is a plain method on `Compiler` — a Scala instance method that happens to share its name with a hypothetical trait. No special handling needed; translate like any other method. + +### Gotcha 11: `evaluate_custom_call` returns `FunctionCallTE`, not `ReferenceExpressionTE` + +Most expression-compiler methods return `ReferenceExpressionTE`. `evaluate_custom_call` returns the narrower `FunctionCallTE` (a specific payload struct per Slab 5). Return `&'t FunctionCallTE<'s, 't>`. Don't accidentally widen to `&'t ReferenceExpressionTE`. + +### Gotcha 12: bodies stay `panic!()` — resist the temptation (restatement of prior Slab Gotchas) + +Several Slab-11 methods have trivial Scala bodies: + +- `evaluate_and_coerce_to_reference_expressions` — 7 lines (a `.map` + unzip). +- `resultify_expressions` — likely short. +- `load_result_ownership` — likely a small match. + +**Don't port them.** Slab 14+ migrates bodies together. + +### Gotcha 13: panic message uses **Slab 14 — body migration** + +Match Slab 10's convention: `panic!("Unimplemented: Slab 14 — body migration");`. Don't re-touch the ~120 stale Slab-10-labeled panic messages elsewhere. + +### Gotcha 14: one-fn impl blocks per TL-HANDOFF convention + +Each method gets its own `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't { pub fn foo(...) { panic!(...) } }` block adjacent to its Scala `/* def ... */` anchor. The existing file structure already has 39 one-fn `impl` wrappers — you're filling in the `(&self)` with real params, not creating new impls. + +### Gotcha 15: Scala `/* */` blocks frozen — pre-commit hook enforces + +Same as every prior slab. `.claude/hooks/check-scala-comments` rejects byte-level edits to `/* */` blocks. + +### Gotcha 16: no downstream breakage expected + +All 39 stubs are `panic!()`. No caller exercises them at runtime. Lifting changes signatures but preserves panic bodies.

This doc. + +You shouldn't need to read the Scala source externally — every Scala `def` sig is already embedded inline in the `/* def ... */` blocks beneath each Rust stub. + +--- + +## The big picture: why Slab 12 exists + +The solver + resolver layer is the type-inference core of the typing pass. Scala organizes it into three sub-compilers (`InferCompiler`, `OverloadResolver`, `ImplCompiler`) plus a `Reachability` utility object. In the god-struct refactor, all four's methods were lifted onto `Compiler<'s, 'ctx, 't>` as bare `pub fn foo(&self) { panic!(...) }` stubs. Your job is to fill in the parameter lists from the Scala `/* def ... */` anchors. + +Two novelties distinguish Slab 12 from prior slabs: + +1. **`IInfererDelegate` vestige cleanup.** Scala's `IInfererDelegate` trait carried ~12 methods used by `compiler_solver.rs` to call back into the compiler (it was a dependency-injection escape hatch to avoid a circular dependency between `InferCompiler` and the "delegate" things it needed). In Rust post-god-struct, those callbacks become plain `self.foo(...)` method calls. The trait is vestigial — an empty `pub trait IInfererDelegate<'s, 't> {}` marker — and its consumer signatures still thread `&dyn IInfererDelegate<'s, 't>` params. **Slab 12 deletes both**: the trait AND the param (just drop `delegate: &dyn IInfererDelegate<'s, 't>` from every fn that takes it in `compiler_solver.rs`, and delete the `pub trait IInfererDelegate<'s, 't> {}` declaration at line 156). +2. **`InferEnv` is a partial placeholder.** Scala's `case class InferEnv(originalCallingEnv, parentRanges, callLocation, selfEnv, region)` is referenced all over Slab-12 Scala sigs. Rust has `pub struct InferEnv<'s>(pub std::marker::PhantomData<&'s ()>)` at `infer_compiler.rs:86` — a single-lifetime phantom placeholder. **Use it as-is** in signatures. Slab 14+ fills in the real fields when bodies land. If you need the type to carry `'t` later, flag it — but for signature work, the phantom single-lifetime form is fine. + +By the end of Slab 12: + +- `cargo check --lib` passes with 0 errors, 0 warnings. +- All 35 bare `(&self)` stubs across the 3 primary files have real signatures. +- `reachability.rs`'s 8 free fns are lifted onto `impl Compiler` per the Slab 9/10 object-to-Compiler convention (or the missing lifetime params are added; see Gotcha 8). +- `IInfererDelegate` trait deleted; `&dyn IInfererDelegate<'s, 't>` params removed from every `compiler_solver.rs` fn signature. +- Bodies remain `panic!("Unimplemented: Slab 14 — body migration");`. +- Scala `/* */` blocks unchanged byte-for-byte. +- Only the 5 target files modified. + +**What Slab 12 is NOT:** + +- No body migration.

If it doesn't exist at all, either (a) the return type is dead code (commented-Scala only) and you don't need it, or (b) use `()` with a TODO. Prefer (a) by reading the Scala body — if the return is `Result[X, Y]` and `Y` isn't defined in Rust, `Y` probably lives in `src/solver/` or is missing and needs grepping. + +### Gotcha 5: reachability.rs free fns — lift to `impl Compiler` (same convention as Slab 9/10 object methods) + +The 7 `visit_*` + 1 `find_reachables` free fns in `reachability.rs` are Scala's `object Reachability` methods.

Leave it as a method on `Reachables`; just ensure the body is `panic!("Unimplemented: Slab 14 — body migration");` (update from the current `"Unimplemented: size"`). + +### Gotcha 6: `HashMap>>` in reachability — by-ref slots + +Reachability's `edges` parameter is a nested map of concrete kind-TT types. Translation: + +```rust +edges: &HashMap, HashMap, Vec<&'t PrototypeT<'s, 't>>>> +``` + +`InterfaceTT` / `StructTT` are Copy (pass by value keys). Inner `Vec<&'t PrototypeT>` holds arena refs. The outer `&` makes the whole thing a read-only borrow. + +Import `std::collections::HashMap` if not already imported (check the file's `use` block). + +### Gotcha 7: `r#continue` — raw identifier, keep the prefix + +Rust reserves `continue`. The stub at `infer_compiler.rs:337` uses `pub fn r#continue(&self)` to bypass the reservation. **Keep the `r#` prefix** in the lifted signature: + +```rust +pub fn r#continue( + &self, + envs: InferEnv<'s>, + state: &mut CompilerOutputs<'s, 't>, + solver: &mut SimpleSolverState, IRuneS<'s>, ITemplataT<'s, 't>>, +) -> Result<(), FailedSolve<'s, 't, IRulexSR<'s>, IRuneS<'s>, ITemplataT<'s, 't>, ITypingPassSolverError<'s, 't>>> { + panic!("Unimplemented: Slab 14 — body migration"); +} +``` + +Don't rename to `continue_` or `do_continue` — that would be a novel Rust divergence. + +### Gotcha 8: `compiler_solver.rs` has its own Scala block structure — leave consumer sigs in place when dropping `delegate` + +`compiler_solver.rs` fn signatures already have real params.

Scala organizes them as `FunctionCompiler`, `FunctionBodyCompiler` (internal impl of FunctionCompiler's lower half), `DestructorCompiler`, `StructCompilerCore`, and the `AnonymousInterfaceMacro`.

The only Slab-13-specific wrinkles: + +1. **`drop` is a valid Rust method name.** Keep `pub fn drop(&self, ...)` in `destructor_compiler.rs`. Not a keyword, no `r#` prefix needed. +2. **Pre-existing Rust-only disambiguation suffixes.** Several Slab-13 methods have suffix disambiguators from prior god-struct work: `_core` (for `struct_compiler_core.rs` vs. `struct_compiler.rs`), `_ext` (for overload resolution when Scala overloaded a name), `_anonymous_interface` (for the macro's helpers). Preserve all these suffixes — they're earlier slab-work and renaming them would diverge from the current Rust-side names. +3. **`IFunctionGenerator` trait is out of scope.** The trait at `compiler.rs:53` has a `generate` method with `()` placeholders. Slab 13 does NOT fill it — it's a Slab 14+ concern (likely becomes a dispatch-tag enum similar to `FunctionBodyMacro`, following the same post-refactor pattern). + +By the end of Slab 13: + +- `cargo check --lib` passes with 0 errors, 0 warnings. +- All 23 target stubs across the 5 files have real signatures. +- Bodies remain `panic!("Unimplemented: Slab 14 — body migration");`. +- Scala `/* */` blocks unchanged byte-for-byte. +- Only the 5 target files modified. +- **The signature-rewrite phase is complete.** The typing pass is shaped; Slab 14+ fills bodies. + +**What Slab 13 is NOT:** + +- No body migration.

Slab 14+ fills the real fields (`prototype: PrototypeTemplataT[...]`, `inferences: Map[...]`, `instantiationBoundArgs: InstantiationBoundArgumentsT[...]` for `EvaluateFunctionSuccess`; `reason: IDefiningError` for `EvaluateFunctionFailure`) and collapses the phantoms. + +**Don't fill the fields in Slab 13.** + +### Gotcha 5: `NodeEnvironmentBox` / `FunctionEnvironmentBoxT` — same Slab-11 translation + +- `NodeEnvironmentBox` → `&mut NodeEnvironmentBuilder<'s, 't>` +- `NodeEnvironmentT` (read-only snapshot) → `&'t NodeEnvironmentT<'s, 't>` +- `FunctionEnvironmentBoxT` → `&mut FunctionEnvironmentBuilder<'s, 't>` +- `FunctionEnvironmentT` (frozen) → `&'t FunctionEnvironmentT<'s, 't>` + +See Slab 11 Gotcha 1 for the full discussion. Both builders exist at `src/typing/env/function_environment_t.rs:1181` (FunctionEnvironmentBuilder) and `:1220` (NodeEnvironmentBuilder). + +### Gotcha 6: `FunctionBannerT` / `FunctionHeaderT` — grep if unsure about arena-allocated vs by-value + +Most AST types from Slab 5 are arena-allocated (`&'t X<'s, 't>`). Grep for the exact types used in Slab 13 signatures: + +- `FunctionHeaderT` — should be `&'t FunctionHeaderT<'s, 't>` +- `FunctionBannerT` — grep `pub struct FunctionBannerT` in `src/typing/ast/`; likely arena-allocated +- `ParameterT` — grep; likely `&'t ParameterT<'s, 't>` + +If a type is Copy (small value), pass by value. If it's a heavy struct (holds arena-referenced children), pass by `&'t`. Default: `&'t` for anything labeled `T` at AST scope. + +### Gotcha 7: closure params in `function_compiler.rs` / `function_body_compiler.rs` + +A few Scala signatures in these files carry continuation closures (similar to the pattern-compiler closures from Slab 11). Same convention: + +```rust +continuation: impl FnOnce( + &mut CompilerOutputs<'s, 't>, + &mut FunctionEnvironmentBuilder<'s, 't>, + // ... other params ... +) -> &'t ReferenceExpressionTE<'s, 't>, +``` + +Use `impl FnOnce` unless the Scala body clearly re-invokes (rare).

Match the precedent: `IEnvEntryT<'s, 't>` by value (it's a wrapper enum; verify Copy). Don't convert to `&'t IEnvEntryT<'s, 't>` unless the compiler complains. + +### Gotcha 9: `IFindFunctionFailureReason` (used in `destructor_compiler.rs`'s `drop` body and possibly as a return) — grep first + +`IFindFunctionFailureReason` is a Scala sealed trait for overload-resolution failure causes. Check if Rust has a corresponding type: + +``` +Grep pattern: "pub (enum|struct) IFindFunctionFailureReason" +``` + +If it exists, use by value or by `&'t` as the pattern dictates. If it doesn't (likely — it may not have been ported yet), and a Slab-13 signature needs it, use `()` with a TODO comment. Fallback pattern from Slab 9 Gotcha 4. + +### Gotcha 10: bodies stay `panic!()` — resist the temptation + +Several Slab-13 methods have short Scala bodies: +- `drop` — 20 lines but mostly a match. +- `get_drop_function` — 8 lines. +- `make_struct_member` — likely a small dispatch. + +**Don't port them.** Slab 14. + +### Gotcha 11: panic message uses "Slab 14 — body migration" + +Match Slabs 10/11/12.

The shape is different from Slabs 8-13: +- Not a signature lift — no `(&self)` stubs to convert. +- Per-type, not per-file.

When `solve_for_defining` returns `Result`, those types existed only as empty placeholders (`pub struct CompleteDefineSolve;` and `pub enum IDefiningError {}`). That was fine for signatures because the bodies were `panic!()` and never constructed instances. + +Body migration changes that. The first body that says `return Err(DefiningSolveFailedOrIncomplete(failed))` requires `IDefiningError` to actually have a `DefiningSolveFailedOrIncomplete(FailedSolve<...>)` variant. The first body that pattern-matches `IBoundArgumentsSource` requires it to be an enum, not an empty marker trait. + +Rather than scatter type-flesh-out across hundreds of body-migration commits — each "I needed `ICompileErrorT::CouldntNarrowDownCandidates` so I added it" commit interleaved with body work — Slab 14 does it all upfront. After Slab 14, every type in the typing pass is shape-complete. Body migration becomes purely about porting the body bodies. + +By the end of Slab 14: + +- All ~15 placeholder types/structs have real Scala-parity fields/variants. +- `IBoundArgumentsSource` is a 2-variant Copy enum (replacing the marker trait). +- `IFunctionGenerator` is a Copy dispatch-tag enum (mirroring `FunctionBodyMacro` precedent). +- `IPlaceholderSubstituter` is defined (as a struct/enum — see Gotcha 9). +- `HinputsT::new()` exists; ~10 `HinputsT` lookup methods have real one-liner bodies. +- The 3 sub-compiler methods (`get_placeholder_substituter`, `get_placeholder_substituter_ext`, `create_rune_type_solver_env`) that returned `()` with TODO get their real return types flipped in. +- The 136 stale `Slab 14 — body migration` panic messages are bulk-updated to `Slab 15 — body migration`. +- `cargo check --lib` clean (0 errors, 0 warnings). +- Scala `/* */` blocks unchanged byte-for-byte. + +**What Slab 14 is NOT:** + +- No body migration of sub-compiler methods (other than the `HinputsT` lookup one-liners).

Two options: + +A. **Delete** `DefaultPrintyThing` entirely (its `print` method was already lifted to `Compiler::print` in Slab 10; the struct was a placeholder). +B. **Keep as unit struct** `pub struct DefaultPrintyThing;` — harmless placeholder, matches Scala's `object` name as a type marker. + +**Recommend**: Option A (delete).

Two fixes: + +A. **Drop `'t` from `IContainer`**: `pub enum IContainer<'s>` with the 4 variants. Remove `_Phantom`. Downstream: any `IContainer<'s, 't>` reference becomes `IContainer<'s>`. Simplest. + +B. **Keep `<'s, 't>` and the `_Phantom`**: body migration may add a `'t`-using variant later (e.g. if a container variant needs to reference a `'t` arena type).

Tuple variants OK for single-field wrappers (e.g. `CitizenDefinitionT::Struct(StructDefinitionT<'s, 't>)`). + +--- + +## Gotchas + +### Gotcha 1: `ExternT` multi-inheritance — one struct, two enum references + +Scala's `ExternT(packageCoord: PackageCoordinate)` extends both `IFunctionAttributeT` and `ICitizenAttributeT`. Rust can't do multiple-inheritance, but you can reference the same struct from two different enums. Convert the existing `_Phantom` `ExternT<'s, 't>` to a real single-field struct (`<'s>` only, since `PackageCoordinate<'s>` is scout): + +```rust +pub struct ExternT<'s> { + pub package_coord: PackageCoordinate<'s>, +} +``` + +Then reference in both: +```rust +pub enum IFunctionAttributeT<'s, 't> { Extern(ExternT<'s>), Pure, Additive, UserFunction } +pub enum ICitizenAttributeT<'s, 't> { Extern(ExternT<'s>), Sealed } +``` + +Hash/Eq concerns: `ExternT` gets derived Copy+Clone+PartialEq+Eq+Hash. Two `ExternT` values from different enum variants are `==` if their package coords are `==`. That's fine for pattern matching. + +### Gotcha 2: lifetime minimization on attribute/unit-heavy enums + +`IFunctionAttributeT` has `Extern(<'s>)` + 3 unit variants. `ICitizenAttributeT` has `Extern(<'s>)` + 1 unit variant. Neither touches `'t`. + +**Decide**: drop `'t` from these enums? + +- Option A: `pub enum IFunctionAttributeT<'s>` (simpler). +- Option B: `pub enum IFunctionAttributeT<'s, 't>` (keep for consumer-type consistency). + +**Recommend**: Option A unless a consumer type forces `'t`. Let cargo drive: start with `<'s>`, add `<'s, 't>` back only if the compiler demands it. + +Same analysis for `IRegionNameT` — if all variants are `<'s>`-only, use `<'s>`. + +### Gotcha 3: `CitizenDefinitionT` enum replacement — check `CompilerOutputs` fields + +Slab 6's `CompilerOutputs` struct has fields like `struct_name_to_definition: HashMap>, &'t StructDefinitionT<'s, 't>>` and `interface_name_to_definition: HashMap<..., &'t InterfaceDefinitionT<'s, 't>>` — stored by concrete type. That's fine; `CitizenDefinitionT` is used in **return** positions for "give me the citizen definition" queries. + +After A1, if a signature returns `CitizenDefinitionT<'s, 't>` (by value) vs returns `&'t CitizenDefinitionT<'s, 't>` (by ref), check the existing sig. Most return-by-value patterns since `CitizenDefinitionT` wraps concrete arena refs (likely `&'t StructDefinitionT`-level is already in the concrete struct). + +Wait — `StructDefinitionT<'s, 't>` is the direct struct, not a ref. So `CitizenDefinitionT::Struct(StructDefinitionT<'s, 't>)` contains a big struct by value. That's expensive to move. **Alternative**: wrap with `&'t`: + +```rust +pub enum CitizenDefinitionT<'s, 't> { + Struct(&'t StructDefinitionT<'s, 't>), + Interface(&'t InterfaceDefinitionT<'s, 't>), +} +``` + +This matches `ICitizenTT`'s precedent from Slab 3 (wraps `&'t StructTT` / `&'t InterfaceTT`). **Recommend**: use `&'t` wrapping. `CitizenDefinitionT` becomes Copy. + +**Audit downstream**: `CompilerOutputs` / `HinputsT` methods that construct/accept `CitizenDefinitionT` may need their signatures adjusted. Let cargo drive. + +### Gotcha 4: `IStructMemberT` / `IMemberTypeT` — ref or value? + +Same question as Gotcha 3. The concrete structs (`NormalStructMemberT`, `VariadicStructMemberT`, `AddressMemberTypeT`, `ReferenceMemberTypeT`) are stored in `StructDefinitionT.members: &'t [IStructMemberT<'s, 't>]` (verify in `citizens.rs`). + +If stored as `&'t [IStructMemberT<'s, 't>]`, the enum itself must be **sized** (can't be `&'t [&'t IStructMemberT<'s, 't>]` — too many indirections). So the enum variants likely hold the concrete structs **by value**: + +```rust +pub enum IStructMemberT<'s, 't> { + Normal(NormalStructMemberT<'s, 't>), + Variadic(VariadicStructMemberT<'s, 't>), +} +``` + +Verify `NormalStructMemberT`'s size (check fields at `citizens.rs:151`) — if it's <= 5 words, by-value is cheap. If it's huge, switch to `&'t NormalStructMemberT<'s, 't>` and audit the slice layout. + +**Default**: by-value. Measure and fix if performance matters later. + +Same for `IMemberTypeT` (smaller — just a `CoordT`). + +### Gotcha 5: `ICalleeCandidate` — same ref-or-value question + +Concrete structs hold single fields (`ft: FunctionTemplataT`, `header: FunctionHeaderT`, `prototypeT: PrototypeT`). `FunctionTemplataT` is Copy (Slab 3); `FunctionHeaderT` likely large (not Copy); `PrototypeT` is `&'t`-wrapped arena. + +**Recommend**: +```rust +pub enum ICalleeCandidate<'s, 't> { + Function(FunctionCalleeCandidate<'s, 't>), // holds FunctionTemplataT (Copy) + Header(&'t HeaderCalleeCandidate<'s, 't>), // &'t because FunctionHeaderT is big + PrototypeTemplata(PrototypeTemplataCalleeCandidate<'s, 't>), // holds &'t PrototypeT +} +``` + +Let cargo / shields guide: if `#[derive(Clone, Debug)]` fails on the enum because `HeaderCalleeCandidate` isn't Clone, switch Header to `&'t` (which is always Copy). + +### Gotcha 6: `ITypingPassSolverError` — grep for the FULL variant list before coding + +The audit says 16 variants; the file has more. **Before touching the enum**, do: + +``` +Grep pattern: "extends ITypingPassSolverError" path: FrontendRust/src/typing/infer/compiler_solver.rs +``` + +Count matches. Add all of them, in file-top-to-bottom order. Don't skip any (even the ones with multi-line Scala blocks). + +### Gotcha 7: lifetime propagation audits after each flip + +Just like Slab 14a: flipping `IFunctionAttributeT<'s, 't>` to `IFunctionAttributeT<'s>` triggers a cascade. Every downstream `IFunctionAttributeT<'s, 't>` reference (in sub-compiler signatures, `FunctionHeaderT` field types, etc.) must be updated. + +Run `cargo check --lib` after each enum flip; let the compiler identify the propagation set. Don't preemptively edit call sites. + +### Gotcha 8: `_Phantom` deletion — remove after the first real variant lands + +Same as Slab 14a Gotcha 6. For each enum being fleshed out, add real variants first, then delete `_Phantom` once the variants use `'s` and `'t` (or only `'s` if lifetime was minimized per Gotcha 2). + +### Gotcha 9: `TookWeakRefOfNonWeakableError` is a Scala Throwable + +Scala throws it as an exception. Rust doesn't do exceptions. Slab 14b just defines it as a unit struct. Slab 15+ decides whether to: +- Fold into `ICompileErrorT` as a variant (`ICompileErrorT::TookWeakRefOfNonWeakable { range: ... }`). +- Leave as a standalone error type used inside `Result<..., TookWeakRefOfNonWeakableError>`. + +**Don't decide now.** Defer to Slab 15. + +### Gotcha 10: `DefaultPrintyThing` deletion vs retention + +If you delete (Option A per E2), verify via grep: +``` +Grep pattern: "DefaultPrintyThing" path: FrontendRust/src +``` + +Should match only Scala `/* */` blocks and the `pub struct DefaultPrintyThing` definition itself. If any non-comment Rust code references it, don't delete — keep as unit struct (Option B). + +### Gotcha 11: `IRegionNameT` grep may find no variants + +Run: +``` +Grep pattern: "extends IRegionNameT" path: FrontendRust/src/typing/names/names.rs +``` + +If 0 matches, keep `_Phantom`. Flag in handback. This is the one exception to the "delete `_Phantom` after variants land" rule — an enum with no variants yet is a legitimate forward-declared type. + +If you find matches, add them following the IDEPFL pattern: each variant wraps `&'t Concrete<'s, 't>`. + +### Gotcha 12: HinputsT lookup bodies — skip per §F + +Do not write new stubs for `HinputsT::lookup_function` etc. Those are new-code, not placeholder-filling. Slab 15+. + +### Gotcha 13: Scala `/* */` blocks are still frozen + +Pre-commit hook enforces. Same as every prior slab. + +### Gotcha 14: bodies stay `panic!()` + +No body migration in Slab 14b.

You're doing Slab 2 — the ~95 name types in `src/typing/names/names.rs`. It's the biggest slab in raw line count, but mechanically repetitive once you've got the first few right.

The postparser has its own `INameS` hierarchy; the typing pass translates those into `INameT` (the "T" suffix is just a Scala convention meaning "typing-pass version", no relation to "type"). Scala's `INameT` is a sealed trait; ~60 concrete `case class`es extend it, and ~14 sub-traits (`IFunctionNameT`, `IStructNameT`, `IVarNameT`, …) slice the hierarchy into groups. + +In Rust, we're turning all of this into: + +- **60 concrete name structs** (`FunctionNameT<'s, 't>`, `StructNameT<'s, 't>`, etc.) — each with real Scala-parity fields.

Each variant holds `&'t SomeConcreteNameT<'s, 't>` (an arena reference). +- **14 sub-enums** (`IFunctionNameT<'s, 't>`, `IStructNameT<'s, 't>`, etc.) — same pattern, but only the concrete names that belong to that group. A given concrete name can appear in multiple sub-enums when Scala had it extending multiple sub-traits (see §6.2 "DAG rule"). This is the most error-prone part of the slab. +- **One generic `IdT<'s, 't, T: Copy>` struct** — `{ package_coord, init_steps, local_name: T }`, with conversion impls (`widen`, `try_narrow`) that move between `IdT<'s, 't, &'t IFunctionNameT<'s, 't>>` and `IdT<'s, 't, &'t INameT<'s, 't>>`. +- **Parallel `Val` enums/structs** (`INameValT`, `IFunctionNameValT`, etc.) that serve as HashMap lookup keys for IDEPFL interning. See that rules file for the rationale; the tl;dr is: reference enums hold `&'s` / `&'t` pointers (can't be constructed without allocating first), so we need a transient lookup key that holds payload by value. The Val is what goes into the `TypingInterner`'s `HashMap` so you can ask "have I interned this before?" without allocating. + +By the end of Slab 2, `names.rs` compiles cleanly (0 errors), nothing past names.rs has been touched, and `cargo check --lib` is still green. Body migration of name types only — no methods, no solver logic, no compiler logic. You're stamping out data-class bodies, adding one enum variant per leaf struct in each sub-enum it belongs to, and wiring up the conversions. + +## What's already in place (don't duplicate; don't delete) + +Open `src/typing/names/names.rs`. You'll see ~95 entries, each in one of two shapes: + +**Shape A — concrete name struct (stub), pre-Step-0:** +```rust +pub struct FunctionNameT<'s, 't>(pub std::marker::PhantomData<(&'s (), &'t ())>); +/* +case class FunctionNameT( + template: FunctionTemplateNameT, + templateArgs: Vector[ITemplataT[ITemplataType]], + parameters: Vector[CoordT] +) extends IFunctionNameT { ... } +*/ +``` + +Your job for each concrete struct is: read the Scala `case class` in the `/* */`, translate the fields into Rust per the arena/lifetime rules, replace the `PhantomData` tuple struct with a named-field struct, delete the `// TODO: placeholder PhantomData — replace with real fields during body migration` line if it exists above the struct. Keep the Scala `/* */` untouched — the pre-commit hook checks it verbatim. + +**Shape B — sub-enum (stub), pre-Step-0:** +```rust +pub enum IFunctionNameT<'s, 't> { _Phantom(std::marker::PhantomData<(&'s (), &'t ())>) } +/* +sealed trait IFunctionNameT extends INameT with IInstantiationNameT { + def template: IFunctionTemplateNameT + def templateArgs: Vector[ITemplataT[ITemplataType]] + ... +} +*/ +``` + +For each sub-enum, read the Scala sealed trait to figure out membership (every concrete `case class` extending this trait is a variant). Replace `_Phantom(...)` with one variant per extending concrete class: `Function(&'t FunctionNameT<'s, 't>)`, `ForwarderFunction(&'t ForwarderFunctionNameT<'s, 't>)`, etc. The variant name is the concrete struct's name minus the trailing `T` (so `FunctionNameT` → variant `Function`). The payload is always `&'t <'s, 't>` — an arena reference, never `Box`, never owned. + +**Don't touch anything outside names.rs** unless this guide explicitly tells you to. If a name struct needs a field of some type that doesn't exist yet (like `templateArgs: Vector[ITemplataT[ITemplataType]]`), use the existing stub. `ITemplataT<'s, 't>` is already defined as a `_Phantom` enum; you can reference it by name. Same with `CoordT<'s, 't>` (already real from Slab 1). + +## Rules for each field translation + +For every Scala case class field, map per these rules: + +| Scala type | Rust type | +|---|---| +| `StrI` | `StrI<'s>` — scout-lifetime-interned string | +| `PackageCoordinate` | `&'s PackageCoordinate<'s>` | +| `IRuneS` (any variant) | `IRuneS<'s>` — already-interned postparser rune | +| `IImpreciseNameS` | `&'s IImpreciseNameS<'s>` | +| `RangeS` / `CodeLocationS` | `RangeS<'s>` / `CodeLocationS<'s>` (both Copy) | +| `CoordT` | `CoordT<'s, 't>` (Copy, inline per §6.4) | +| `ITemplataT[...]` | `ITemplataT<'s, 't>` (small enum, passed by value; `_Phantom` for now — it'll grow in Slab 3) | +| `INameT` sub-trait like `IFunctionNameT` | `&'t IFunctionNameT<'s, 't>` | +| Concrete `FunctionNameT` / `StructTemplateNameT` / … | `&'t FunctionNameT<'s, 't>` (through the arena) | +| `Vector[T]` of interned/arena-stored items | `&'t [T]` (arena slice) — e.g. `&'t [ITemplataT<'s, 't>]`, `&'t [CoordT<'s, 't>]`, `&'t [&'t INameT<'s, 't>]` | +| `Int` | `i32` | +| `Long` | `i64` | +| `Boolean` | `bool` | +| `IdT[SomeNameT]` | `IdT<'s, 't, &'t SomeNameT<'s, 't>>` (the generic parameter is the *leaf* type) | + +Every concrete name struct gets `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` — they're small (pointers and Copy primitives only), Copy by design per ATDCX. The structs are output data; no `Vec`, `HashMap`, or `String` fields ever (AASSNCMCX). Every collection field is an arena slice `&'t [...]` or `&'s [...]`. + +Every sub-enum `INameT`, `IFunctionNameT`, etc. gets `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` too — they're tagged pointers. + +Add `where 's: 't` as an impl-block-level bound on anything that transitively holds `&'s` data (§1.2). The struct/enum definitions themselves don't need the bound — the bound comes in when you write `impl<'s, 't> FunctionNameT<'s, 't> where 's: 't { ... }`. + +## The DAG rule (§6.2) — the trap + +Some Scala concrete names extend **multiple** sub-traits. Example from `names.rs`: + +```scala +case class ExternFunctionNameT(...) extends IFunctionNameT with IFunctionTemplateNameT { ... } +``` + +`ExternFunctionNameT` is *both* an `IFunctionNameT` and an `IFunctionTemplateNameT`. In Rust, this means `ExternFunctionNameT` appears as a variant **in both** sub-enums: + +```rust +pub enum IFunctionNameT<'s, 't> { + Function(&'t FunctionNameT<'s, 't>), + ExternFunction(&'t ExternFunctionNameT<'s, 't>), // shared with IFunctionTemplateNameT + Forwarder(&'t ForwarderFunctionNameT<'s, 't>), + // ... +} + +pub enum IFunctionTemplateNameT<'s, 't> { + FunctionTemplate(&'t FunctionTemplateNameT<'s, 't>), + ExternFunction(&'t ExternFunctionNameT<'s, 't>), // shared with IFunctionNameT + // ... +} +``` + +Both variants point at the *same* `&'t ExternFunctionNameT` pointer — the scout arena allocates one `ExternFunctionNameT`, and two enum tags (one in `IFunctionNameT`, one in `IFunctionTemplateNameT`) can wrap it. The enums are just differently-tagged views over the same arena payload. + +**How to find the DAG memberships.** For each concrete struct, look at its Scala `case class ... extends A with B with C` line and split on `with`. Those are the traits it extends. Each of those (if it maps to one of our 14 Rust sub-enums) gets a variant. + +Map from Scala sub-trait name to Rust sub-enum name: + +| Scala sub-trait | Rust sub-enum | +|---|---| +| `INameT` | `INameT` (top-level) | +| `ITemplateNameT` | `ITemplateNameT` | +| `IFunctionTemplateNameT` | `IFunctionTemplateNameT` | +| `IFunctionNameT` | `IFunctionNameT` | +| `IInstantiationNameT` | `IInstantiationNameT` | +| `ISubKindTemplateNameT` | `ISubKindTemplateNameT` | +| `ISuperKindTemplateNameT` | `ISuperKindTemplateNameT` | +| `ISubKindNameT` | `ISubKindNameT` | +| `ISuperKindNameT` | `ISuperKindNameT` | +| `ICitizenTemplateNameT` | `ICitizenTemplateNameT` | +| `ICitizenNameT` | `ICitizenNameT` | +| `IStructTemplateNameT` | `IStructTemplateNameT` | +| `IStructNameT` | `IStructNameT` (inside `CitizenNameT` grouping — confirm against existing Rust `pub enum CitizenNameT` shape) | +| `IInterfaceTemplateNameT` | `IInterfaceTemplateNameT` | +| `IInterfaceNameT` | `IInterfaceNameT` | +| `IImplTemplateNameT` | `IImplTemplateNameT` | +| `IImplNameT` | `IImplNameT` | +| `IRegionNameT` | `IRegionNameT` | +| `IVarNameT` | `IVarNameT` | +| `IPlaceholderNameT` | `IPlaceholderNameT` | + +If Scala uses a sub-trait that you can't find in the list above (happens rarely — e.g. `IInterning`, `Equatable`), it's a Scala marker trait with no Rust counterpart. Ignore it; it does not map to a Rust enum variant. + +**If a concrete struct extends a sub-trait transitively** (`X extends IFunctionNameT` where `IFunctionNameT extends INameT`): you still put `X` as a variant in `IFunctionNameT` **and** in `INameT`. Both. The top-level `INameT` enum is the "everything" union; every concrete struct is a variant there regardless of which sub-traits it extends. + +## The `IdT<'s, 't, T: Copy>` generic + +Read `quest.md` §6.3 carefully before you start on `IdT`. The salient points: + +```rust +pub struct IdT<'s, 't, T: Copy> +where 's: 't, +{ + pub package_coord: &'s PackageCoordinate<'s>, + pub init_steps: &'t [&'t INameT<'s, 't>], + pub local_name: T, +} +``` + +- `T: Copy` is the only bound on the struct itself. Keep it minimal. +- `init_steps` is an arena slice of `&'t INameT<'s, 't>` pointers (so every step is an already-widened `&'t INameT` — the widest form). +- `local_name: T` holds the leaf-kind-specific type (e.g. `&'t IFunctionNameT<'s, 't>` or `&'t StructTemplateNameT<'s, 't>`). +- Conversion methods live in separate `impl` blocks with conversion-specific bounds: + - `widen` — `T: Into<&'t INameT<'s, 't>>`, narrow → wide + - `widen_to` — generic upcast, `T: Into` + - `try_narrow` — `&'t INameT<'s, 't>: TryInto`, wide → narrow (fallible) +- `Copy + Clone` derives on `IdT<'s, 't, T>` itself (it's a pointer triple + a small `T`). + +You also need `From`/`TryFrom` impls between sub-enums (wide→narrow and narrow→wide). For each concrete name `XxxNameT` that appears in sub-enum `IYyyNameT`, generate: + +```rust +impl<'s, 't> From<&'t XxxNameT<'s, 't>> for IYyyNameT<'s, 't> { + fn from(x: &'t XxxNameT<'s, 't>) -> Self { IYyyNameT::Xxx(x) } +} +``` + +For narrowing, use `TryFrom` returning `Option<...>` (or `Result<_, ()>`). You don't strictly need `TryFrom` for every narrowing — only the ones that `IdT::try_narrow` needs. Start with the obvious ones (`INameT` → each sub-enum) and add more as needed. + +## IDEPFL — the dual-enum Val pattern + +Read `.claude/rules/postparser/IDEPFL-postparser-interning.md` before writing any `Val`. The pattern is used in the postparser and we're replicating it in the typing pass for these four families: + +1. `INameT<'s, 't>` ↔ `INameValT<'s, 't>` +2. `IdT<'s, 't, T>` ↔ `IdValT<'s, 't, T>` +3. Each of the 14 sub-enums gets a `*ValT` companion (e.g. `IFunctionNameT` ↔ `IFunctionNameValT`). +4. Each concrete name struct either needs its own `XxxNameValT` struct or can reuse itself as its own Val (the "Simple" case from IDEPFL — when the struct contains only Copy fields and no `&'t` children). + +**How to decide if a concrete name needs a separate Val struct:** + +- **Simple** (no separate Val): The struct's fields are all Copy primitives or scout-lifetimed refs (`StrI<'s>`, `IRuneS<'s>`, `RangeS<'s>`, `&'s PackageCoordinate<'s>`). There are no `&'t` fields. Example: `CodeVarNameT<'s, 't> { name: StrI<'s> }` — the Val is just the same struct by value. The sub-enum's Val variant looks like `CodeVarName(CodeVarNameT<'s, 't>)`. +- **Shallow** (separate Val with same shape): The struct holds `&'t` refs to already-interned types. The Val struct holds the same fields but by value (still `&'t` refs, since those are owned pointer-sized tags — canonical). Example: `FunctionNameT<'s, 't> { template: &'t FunctionTemplateNameT<'s, 't>, ... }` — Val: `FunctionNameValT<'s, 't> { template: &'t FunctionTemplateNameT<'s, 't>, ... }`. Same fields. +- **Transient with `'tmp`** (separate Val with borrowed slices): The struct holds `&'t [...]` slices. The Val holds `&'tmp [...]` borrowed slices (slices allocated lazily on a miss inside the intern method). This follows the `@DSAUIMZ` / `ImmediateInterningDiscipline-IIDX` shield — keep the slice on the stack until we confirm a miss, then promote. Example: `IdT<'s, 't, T>` has `init_steps: &'t [&'t INameT<'s, 't>]` — Val: `IdValT<'s, 't, 'tmp, T>` with `init_steps: &'tmp [&'t INameT<'s, 't>]`. + +The postparser names file (`FrontendRust/src/postparsing/names.rs`) has a complete worked example of all three kinds. You will consult that file constantly during Slab 2. That's the reference. + +**Do not implement the `TypingInterner` intern methods themselves in Slab 2.** The intern methods live in `src/typing/typing_interner.rs` and are currently `panic!()` stubs. Leave them alone — body-filling those is part of Slab 3 or its own mini-slab. All you're doing in Slab 2 is *defining* the Val types so the interner signatures type-check. Construction of the actual `HashMap` storage inside `TypingInterner` is a separate workstream. + +## Step-by-step plan + +Work bottom-up — concrete structs first, then sub-enums once their variants exist, then the top-level `INameT`, then `IdT` and conversions. + +### Step 0: Strip all `// mig:` markers (prerequisite cleanup) + +The `// mig: struct ...` / `// mig: enum ...` / `// mig: fn ...` / `// mig: impl ...` / `// mig: trait ...` markers are an artifact of the slice pipeline — they existed so slicing scripts could match each Rust definition to its Scala counterpart. Slicing is done, the pipeline has been fully consumed across `src/typing/`, and the markers no longer serve a purpose. The `/* scala */` blocks remain as the audit trail; those are what the pre-commit hook enforces, not the `// mig:` lines. + +Do a pre-pass before starting Slab 2 work: sweep across all of `src/typing/` (including subdirs like `macros/`, `citizen/`, `function/`, `expression/`, `infer/`, `names/`, `templata/`, `ast/`, `env/`, `types/`) and delete every `// mig:` comment line. + +Examples of lines to delete (there are ~500+ of them): + +``` +// mig: struct FunctionNameT +// mig: enum IFunctionNameT +// mig: fn generate_function_body_lock_weak +// mig: impl Compiler +// mig: trait IFunctionGenerator +``` + +**Rules for the cleanup:** + +- **Delete only lines whose content starts with `// mig:`** (optionally preceded by whitespace). Don't delete anything else — in particular, don't touch `// TODO: placeholder PhantomData` lines (those flag stubs that later slabs will resolve) or `// vestigial:` notes (those flag intentional workarounds) or `// (no scala counterpart ...)` notes. +- **Preserve surrounding whitespace.** When deleting a `// mig:` line, remove the entire line including its newline — don't leave a blank line where it was unless the file had a blank line there before the marker was inserted. +- **Don't change the `/* scala */` blocks.** The pre-commit hook is strict about them; see Gotcha 1 below. +- **Do NOT run this as a bulk `sed`** against the whole tree in one go. The project's `CLAUDE.md` has a whole "Bulk Sed Safety Protocol" section; follow it. Safer approach: + - Run per-file (or per-subdir) with the `Edit` tool. + - After each batch of ~5 files, run `cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-2.txt 2>&1` and confirm `grep -c "^error" /tmp/sylvan-slab-2.txt` is still 0. If it jumped, you accidentally deleted something that wasn't a `// mig:` line (or deleted one that actually was a load-bearing annotation — shouldn't happen, but verify). + - If you *do* want to use `sed` on a single file as a time saver, dry-run it first: `sed "/^\s*\/\/ mig:/d" FILE | diff FILE -`, eyeball the diff, then apply with `sed -i ''` (macOS) only if it looks right. +- **Expected scope:** ~500+ markers across ~90 files. Ballpark a few hours of mechanical work. Commit the whole sweep as one commit ("Strip `// mig:` markers from src/typing/ — slice pipeline artifacts, no longer needed"). `cargo check --lib` must stay at 0 errors throughout (it should — deleting line comments can't break code). + +After this cleanup is committed, move to Step 1. From here on out — including in Slab 2 itself — do not add `// mig:` markers to any new code. + +### Step 1: Confirm your starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-2.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-2.txt +``` + +That should say `0`. If it doesn't, stop and tell the senior. + +Note: the project sets `#![allow(unused_variables, unused_imports)]` in `src/lib.rs`, so warnings are suppressed. Don't rely on the warning count — it'll always be 0. Rely on error count. + +### Step 2: Concrete name structs (do ~60 of them, one at a time) + +Order doesn't matter much — you can do alphabetical, or bottom-up from leafless ones. I recommend: start with a very simple one like `CodeVarNameT` to feel out the process, then bang through the rest. + +For each concrete struct: + +1. Read its Scala `case class` in the `/* */` block below it. +2. Figure out each field's Rust type per the translation table above. +3. Replace the `pub struct XxxNameT<'s, 't>(pub std::marker::PhantomData<(&'s (), &'t ())>);` line with a real `pub struct XxxNameT<'s, 't> { pub field1: T1, pub field2: T2, ... }`. +4. Delete any `// TODO: placeholder PhantomData — replace with real fields during body migration` line immediately above the struct (that comment is only for Phase-1-era stubs). +5. Add `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` above the struct. +6. Leave the `/* scala */` block untouched. (The `// mig:` markers will have been deleted in Step 0.) + +Do **not** write `impl XxxNameT { ... }` blocks. The Scala class bodies have lots of derived methods (`def packageId`, `def steps`, etc.) — those are Slab 8/9+ work. Just the struct bodies. + +**Every few structs, run `cargo check --lib` to catch mistakes early.** Early errors are cheap to fix; late errors require scrolling through a dozen failing call sites. + +### Step 3: Sub-enums (14 of them) + +For each `pub enum IXxxNameT<'s, 't> { _Phantom(...) }`: + +1. Scan `/* */` text above and below for `extends IXxxNameT` occurrences to find the concrete names that belong. +2. Replace `_Phantom(...)` with one variant per belonging concrete name: `Xxx(&'t XxxNameT<'s, 't>)`. +3. Add `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]`. +4. Keep a scratch list as you go of which concrete names you've placed into which sub-enums. Cross-reference the DAG rule. A concrete name that extends `A with B with C` should appear in `A`, `B`, and `C`. + +The top-level `INameT<'s, 't>` is a special case: **every** concrete name is a variant of `INameT`. That's the union-of-everything enum. + +### Step 4: `IdT<'s, 't, T: Copy>` + +1. Replace `pub struct IdT<'s, 't>(pub std::marker::PhantomData<(&'s (), &'t ())>);` with the three-field struct per §6.3. +2. Add `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]`. +3. Add `where 's: 't,` clause. +4. Add `impl<'s, 't, T: Copy + ...> IdT<'s, 't, T> { widen / widen_to / try_narrow }` in separate impl blocks per their conversion bounds. + +### Step 5: `From` / `TryFrom` bridges + +For each concrete name `XxxNameT` belonging to sub-enum `IYyyNameT`: + +```rust +impl<'s, 't> From<&'t XxxNameT<'s, 't>> for IYyyNameT<'s, 't> { + fn from(x: &'t XxxNameT<'s, 't>) -> Self { IYyyNameT::Xxx(x) } +} +``` + +For each sub-enum `IYyyNameT` narrowing from `INameT`: + +```rust +impl<'s, 't> TryFrom<&'t INameT<'s, 't>> for &'t IYyyNameT<'s, 't> { + type Error = (); + fn try_from(n: &'t INameT<'s, 't>) -> Result { ... } +} +``` + +(You might need a `match` inside `try_from` that pattern-matches on `INameT`'s variants and returns `Ok(...)` for the subset. This can get tedious; only write the bridges that `IdT::try_narrow` or higher-layer code actually needs. Start minimal; add as downstream build errors surface.) + +### Step 6: `*ValT` companions + +Per IDEPFL. Goes adjacent to each name type: + +- For each simple-kind concrete `XxxNameT`: no separate Val needed, the sub-enum's Val variant holds `XxxNameT<'s, 't>` by value. +- For each shallow-kind concrete `XxxNameT`: add `pub struct XxxNameValT<'s, 't> { ...same fields... }`. The sub-enum's Val variant holds `XxxNameValT<'s, 't>`. +- For `IdT`, add `pub struct IdValT<'s, 't, 'tmp, T: Copy> { package_coord: &'s PackageCoordinate<'s>, init_steps: &'tmp [&'t INameT<'s, 't>], local_name: T }`. +- Top-level `INameValT<'s, 't>` with one variant per concrete name, payload per the rules above. + +Mark these as "(no scala counterpart — Rust-only interning scaffolding)" with a `//` line comment above each Val type. Do **not** put them inside `/* */` blocks — the pre-commit hook will yell. + +### Step 7: Verify and commit + +```bash +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-2.txt 2>&1 +tail -30 /tmp/sylvan-slab-2.txt +grep -c "^error" /tmp/sylvan-slab-2.txt +``` + +Must be 0 errors. If not, triage one at a time from the top of the file. + +Commit when clean: + +```bash +git add FrontendRust/src/typing/names/names.rs +git commit -m "$(cat <<'EOF' +Typing Slab 2: flesh out name hierarchy — IdT generic + ~60 concrete +names + 14 sub-enums + IDEPFL Val companions. + + + +Error count stays at 0. + +Co-Authored-By: Claude +EOF +)" +``` + +## Gotchas (the senior hit these on Slab 1) + +1. **Pre-commit hook on `/* */` blocks.** `.claude/hooks/check-scala-comments` runs before every commit and does exact-match comparison between every `/* */` block and the Scala source. If you accidentally put English prose inside a `/* */` or reformat Scala, the commit is rejected. Corollary: when you add the separate `Val` struct, use `//` line comments to explain it — never `/* */`. + +2. **`IdT` generic is contagious.** As soon as `IdT` has a real body, everything that holds `IdT<'s, 't>` without specifying `T` breaks. Check usages before Step 4: `grep -rn "IdT<'s, 't>" FrontendRust/src/typing/`. You'll find callers in `types/types.rs`, `names/names.rs`, `ast/citizens.rs`, and expression types. Most of them want `IdT<'s, 't, &'t IXxxNameT<'s, 't>>` for the specific leaf kind Scala was using. Before writing the `IdT` body, expand the existing `IdT<'s, 't>` callers into `IdT<'s, 't, &'t NameT<'s, 't>>`. Do this as small, separate edits — it makes blame archaeology easier. + +3. **`_Phantom` stays on `KindT`.** Slab 1 added six primitive variants to `KindT` but kept `_Phantom` so the `<'s, 't>` lifetimes are anchored until Slab 3 adds non-primitive variants. Don't touch `KindT`. It's not your slab. + +4. **Arena parameters on fn signatures.** If you write any helper fn that takes an arena (you probably don't need to in Slab 2), use `&ScoutArena<'s>` or `&'ctx ScoutArena<'s>` — never `&'s ScoutArena<'s>`. See §1.2 invariant 5. + +5. **Don't derive `Clone` without `Copy` on arena-allocated types.** ATDCX shield. Since every concrete name is `Copy` by design (all fields Copy), derive both. + +6. **DAG membership is asymmetric.** `ExternFunctionNameT extends IFunctionNameT with IFunctionTemplateNameT` means both sub-enums get a variant, but the *structs* themselves don't know about each other. Each sub-enum independently lists the concrete names that belong. + +7. **Existing Rust cross-references.** Some types outside `names.rs` currently reference specific name types (e.g. `StructTT<'s, 't> { name: IdT<'s, 't> }` in `types/types.rs`). When `IdT` becomes generic in Step 4, these references turn into compile errors. Update each caller to the specific leaf-type version — `StructTT::name` should become `IdT<'s, 't, &'t IStructNameT<'s, 't>>` per Scala (Scala has `IdT[IStructNameT]`). + +8. **Commit cadence.** One commit per sub-slab: + - Concrete structs (maybe split into 2 commits if it's many) + - Sub-enums + - IdT + conversions + - Val companions + bridges + + It's fine to collapse some steps if you're confident and the diff stays readable. If you end up with one giant commit, that's OK too — but make sure the build is clean at commit time. + +## What "done" looks like + +- `cargo check --lib` passes with 0 errors. +- Every concrete name struct has real fields and Copy derives. +- Every sub-enum has real variants (no more `_Phantom`) and Copy derives. +- Every concrete name appears as a variant in every sub-enum it transitively extends in Scala (the DAG rule). +- `IdT<'s, 't, T: Copy>` is a real struct with the three fields from §6.3, plus `widen`/`widen_to`/`try_narrow` impl blocks. +- `INameValT` + 14 sub-enum Vals + per-concrete Val structs (where the IDEPFL Shallow/Transient patterns apply) exist and compile. +- `From`/`TryFrom` bridges between sub-enums exist where needed. +- The `TypingInterner` intern methods remain `panic!()` stubs — not your problem. +- `src/typing/typing_interner.rs` unchanged (unless a signature needs a tiny adjustment to reference the now-real types; check with the senior first if so). +- No files outside `names.rs` substantively changed, except: + - Small call-site updates in `types/types.rs`, `ast/citizens.rs`, `ast/expressions.rs`, etc. to specialize `IdT<'s, 't>` with explicit `T` arguments.

If a dependency type isn't Copy yet, add Copy derives to *that* type (if it's a name type you own) or wrap the field in `&'t` (if it's a larger type not yours). +- **A Scala field has a type you don't recognize**: search its `pub struct` or `pub enum` in `src/typing/` to see what Rust name maps to it. +- **The DAG membership for a concrete name is ambiguous**: grep the Scala block for `extends X with Y with Z`, split, look each up.

Most of the "Rules for each field translation" table there applies verbatim to Slab 3. +5. This doc. + +**Important design note up front:** Slab 2 made a significant design refactor that `quest.md` §6.5 doesn't fully reflect yet — name sub-enum families (`IFunctionNameT`, `IStructNameT`, `INameT`, etc.) were moved from arena-interned wrappers to inline-owned 16-byte `Copy` values. When you hit the analogous question for `KindT`'s ICitizenTT/ISubKindTT/ISuperKindTT sub-enums, stop and ask the senior whether to apply the same pattern. See "Gotcha 1" below. + +You shouldn't need to read the Scala source externally — every Scala `case class` / sealed trait is already embedded inline in the `/* ... */` blocks in both files. If you can't figure out what a Scala type does from its block, ask; don't guess. + +## The big picture: why Slab 3 exists + +Three orthogonal type hierarchies live together in this slab: + +1. **Kind** (`KindT<'s, 't>`) — Scala's `KindT` sealed trait. This is "what kind of thing is this type?" — a struct, an interface, an int, a placeholder, etc. Already has its ~6 primitive variants (Slab 1 did Never/Void/Int/Bool/Str/Float). Slab 3 adds the ~6 non-primitive variants (Struct/Interface/StaticSizedArray/RuntimeSizedArray/KindPlaceholder/OverloadSet). + +2. **Coord** (`CoordT<'s, 't>`) — ownership + region + kind. The type of *a reference to* a thing. `share int`, `own MyStruct`, `borrow &MyClass`. Small Copy struct; Slab 1 already got its three fields. In Slab 3 you mostly leave `CoordT` alone but verify the derives match the new pattern. + +3. **Templata** (`ITemplataT<'s, 't>`) — generic-parameter arguments. When you call `foo`, the typing pass resolves `int` and `MyStruct` into `ITemplataT::Kind(...)` and/or `ITemplataT::Coord(...)` values that get stuffed into an `IdT`'s `template_args`. Scala's `ITemplataT[+T <: ITemplataType]` has a phantom outer-type parameter that's **erased** in the Rust port (per §6.6) — the Rust enum is plain `ITemplataT<'s, 't>` with no outer parameter. The enum has 19 variants from small value-kinds (integer, boolean) to heavy ones holding `&'s FunctionA` references. + +By the end of Slab 3: + +- `cargo check --lib` passes with 0 errors. +- `types/types.rs` has `KindT` with all variants filled, plus `ICitizenTT`/`ISubKindTT`/`ISuperKindTT` sub-enums with real variants (DAG rule applies, but it's a tiny DAG). +- `templata/templata.rs` has `ITemplataT` with all 19 variants and real field-bearing payload structs for each. +- `PrototypeT<'s, 't, T: Copy = ()>` and `SignatureT<'s, 't>` already have fields from Slab 2; verify and leave alone. +- IDEPFL `*ValT` companion types for the newly-interned families: `KindValT`, `ITemplataValT`, `PrototypeValT`, `SignatureValT`.

This deviates from quest.md §6.5 which shows `Struct(StructTT<'s, 't>)` inline; the resolution is documented in `docs/reasoning/idt-typed-view-alternatives.md` alongside the IdT decision (same philosophy: concrete payloads interned for pointer-identity, wrappers inline for free casts). + +## The quest.md §6.6 reference `ITemplataT` shape + +Per §6.6, `ITemplataT` has 19 variants. The Scala `ITemplataT[+T <: ITemplataType]` outer phantom parameter is **erased** in Rust: + +```rust +pub enum ITemplataT<'s, 't> { + // Leaf-like (all Copy-by-value) + Coord(&'t CoordTemplataT<'s, 't>), + Kind(&'t KindTemplataT<'s, 't>), + Placeholder(&'t PlaceholderTemplataT<'s, 't>), + Mutability(MutabilityTemplataT), + Variability(VariabilityTemplataT), + Ownership(OwnershipTemplataT), + Integer(i64), + Boolean(bool), + String(&'s StrI<'s>), // scout-lifetimed StrI is fine + Prototype(&'t PrototypeTemplataT<'s, 't>), + Isa(&'t IsaTemplataT<'s, 't>), + CoordList(&'t CoordListTemplataT<'s, 't>), + RuntimeSizedArrayTemplate(RuntimeSizedArrayTemplateTemplataT), + StaticSizedArrayTemplate(StaticSizedArrayTemplateTemplataT), + + // Heavy — carry direct &'s refs, like Scala (not interned themselves) + Function(&'t FunctionTemplataT<'s, 't>), + StructDefinition(&'t StructDefinitionTemplataT<'s, 't>), + InterfaceDefinition(&'t InterfaceDefinitionTemplataT<'s, 't>), + ImplDefinition(&'t ImplDefinitionTemplataT<'s, 't>), + ExternFunction(&'t ExternFunctionTemplataT<'s, 't>), +} +``` + +Note the **mixed-mode equality** per §6.6: Copy-value variants compare by value; `&'t`-ref variants compare by pointer identity (relying on interner uniqueness). `ITemplataValT` mirrors the split. This matches the pattern you see in the names work (inline values vs interned refs), so it should feel familiar. + +Heavy templata payloads (`FunctionTemplataT` etc.) hold scout-lifetime refs directly. These are **not** interned (they're `allocated but not interned` per §1.5). For example: + +```rust +pub struct FunctionTemplataT<'s, 't> { + pub outer_env: &'s IEnvironmentT<'s, 't>, + pub function: &'s FunctionA<'s>, +} +``` + +`IEnvironmentT` is a Slab 4 type — there's a placeholder enum/trait in `env/environment.rs`. Use it as-is; don't redefine. + +## IDEPFL `*ValT` companions + +Per the Gotcha 1 resolution, the scope here is narrower than quest.md §6.1 suggested. Wrapper enums (`KindT`, its three sub-enums, and `ITemplataT`) are all inline-owned and do NOT need Val types. The concrete *payloads* are what get interned. + +**Vals to add** (for interned concrete Kind payloads + interned templata payloads + `PrototypeT` + `SignatureT`): + +1. **Per-concrete Kind payload Vals** (all simple/shallow — reuse the struct as its own Val, like Slab 2 did for ~45 concrete names): + - `StructTT<'s, 't> { id: IdT<'s, 't> }` — Val = the struct itself (`IdT` is already canonical). + - `InterfaceTT<'s, 't>`, `StaticSizedArrayTT<'s, 't>`, `RuntimeSizedArrayTT<'s, 't>`, `KindPlaceholderT<'s, 't>` — same pattern. + - `OverloadSetT<'s, 't> { env: &'s IEnvironmentT<'s, 't>, name: &'s IImpreciseNameS<'s> }` — scout-lifetime fields only; simple reuse. + + No separate `*ValT` types needed. Document this as a comment in `types/types.rs` matching the Slab 2 "~45 simple/shallow concretes reuse struct as Val" comment block. + +2. **Per-interned-templata-payload Vals** (in `templata/templata.rs`): like the concrete Kind payloads, these are shallow and can mostly reuse their struct as their own Val — except `CoordListTemplataT` has an arena slice (`&'t [CoordT<'s, 't>]`), so it gets a transient `CoordListTemplataValT<'s, 't, 'tmp>` with the `'tmp`-borrowed slice. The other five (`CoordTemplataT`, `KindTemplataT`, `PlaceholderTemplataT`, `PrototypeTemplataT`, `IsaTemplataT`) hold only `&'t` refs to already-canonical data — reuse the struct as its own Val and note it in the comment block (same convention as Slab 2 Step 6's ~45 simple/shallow concretes). + + `ITemplataT<'s, 't>` itself is inline-owned (not interned) — same philosophy as `KindT`. No `ITemplataValT` type. Remove the stub from `typing_interner.rs`. + +3. **`PrototypeValT<'s, 't, 'tmp>`** — moves into `ast/ast.rs` next to `PrototypeT`. Since `PrototypeT<'s, 't>` has `id: IdT<'s, 't>` and `return_type: CoordT<'s, 't>`, and `IdT` contains a `&'t [INameT]` slice, `PrototypeValT` needs the `'tmp` lifetime for the inner `IdValT<'s, 't, 'tmp>`. No generic T — Slab 2's monomorphic refactor dropped it. + +4. **`SignatureValT<'s, 't, 'tmp>`** — moves into `ast/ast.rs` next to `SignatureT`. `SignatureT { id: IdT<'s, 't> }`, so `SignatureValT<'s, 't, 'tmp> { id: IdValT<'s, 't, 'tmp> }`. Same `'tmp`-for-init_steps pattern as `PrototypeValT`. + +For each `*ValT`, add `#[derive(Copy, Clone, Debug)]` plus custom `PartialEq`/`Eq`/`Hash` *if* the struct has slices or fields where structural hashing isn't enough. If the Val is pure Copy + structural-eq'able (no slices, no `&'s` refs needing pointer-eq), just derive all six traits. + +Finally, update `typing_interner.rs`: +- **Remove** `intern_kind` (KindT no longer interned) and `intern_templata` (ITemplataT inline). +- **Keep** `intern_id`, `intern_prototype`, `intern_signature` stubs with their current signatures (intern_prototype/signature gain the `'tmp` param to match their Val types). +- **Do NOT add** per-payload intern methods (`intern_struct_tt`, `intern_coord_templata`, etc.). Following Slab 2 Step 6's precedent — Val types get defined in this slab; the per-family intern method API is designed when the interner body is actually implemented (Slab 4+).

Your implementation changes depending on the answer. Don't guess. + +### Step 3 — Fill `KindT` non-primitive variants + sub-enums (types/types.rs) + +1.

Add `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` to all four enums if not already present. +4. Add `From<&'t StructTT<'s, 't>> for KindT<'s, 't>` / `From<&'t InterfaceTT<'s, 't>> for KindT<'s, 't>` / etc. (concrete → wrapper), plus the narrow → wide cascade (`From> for KindT<'s, 't>` etc.), plus `TryFrom> for ICitizenTT<'s, 't>` etc. Mirror the Slab 2 names bridges. +5. Leave `/* scala */` blocks untouched. +6. Remove any `// TODO: placeholder PhantomData` comments immediately above each filled definition. +7. Run `cargo check --lib` per the session-file convention. + +Expected fallout: dozens of downstream uses of `KindT<'s, 't>` pattern-match on variants; they may now have new variants unhandled.

Rust's `derive` delegates to the field's `Hash` impl, so this should Just Work. If it doesn't, add custom Hash/Eq mirroring the IdT pattern. + +### Step 6 — IDEPFL `*ValT` companions + +Per "IDEPFL `*ValT` companions" section above. Move each `*ValT` stub out of `typing_interner.rs` into its home file, expand it to a real Val type with real variants / fields: + +1. **`KindValT`** — into `types/types.rs` right after `KindT`. +2. **`ITemplataValT`** — into `templata/templata.rs` right after `ITemplataT`. +3. **`PrototypeValT`** — into `ast/ast.rs` right after `PrototypeT`.

They already contain `IdT<'s, 't>` or heavy scout refs; interning gives them pointer-identity. + +**Inline-owned 16-byte Copy enums (never arena-allocated):** +- `KindT<'s, 't>`, `ICitizenTT<'s, 't>`, `ISubKindTT<'s, 't>`, `ISuperKindTT<'s, 't>`. +- Primitive KindT payloads (`NeverT`, `VoidT`, `IntT`, `BoolT`, `StrT`, `FloatT`) stay inline as variants of `KindT` itself — no arena round-trip for `KindT::Int(IntT { bits: 32 })`. + +**Why this shape (and why it deviates from §6.5):** + +1. Matches the Slab 2 names refactor exactly. Concrete names are interned (`&'t FunctionNameT`); wrapper enums (`INameT`, `IFunctionNameT`, etc.) are inline 16-byte values. Applying the same philosophy here keeps the typing pass' storage model uniform. +2. `&'t KindT<'s, 't>` everywhere (the literal §6.5 approach) wasn't what the code already had — `CoordT.kind` is already inline `KindT<'s, 't>`. Making KindT 16 bytes (tag + 8-byte ref) keeps CoordT small (~24 bytes including ownership + region). +3. Casts between `KindT`, `ICitizenTT`, `ISubKindTT`, `ISuperKindTT` become stack-only rewraps — `From`/`TryFrom` impls can be real (no interner round-trip). +4. Concrete payloads (`StructTT`, etc.) keep pointer-identity via interning, which is what `HashMap<&'t StructTT, V>` callers rely on. + +**No Val type for KindT or its sub-enums.** Since they're inline-owned (not arena-interned), they don't need IDEPFL Val companions. The six interned concrete Kind payloads (`StructTT`, `InterfaceTT`, `StaticSizedArrayTT`, `RuntimeSizedArrayTT`, `KindPlaceholderT`, `OverloadSetT`) are all simple/shallow and reuse themselves as their own Val per the Slab 2 Step 6 convention — no separate `*ValT` types needed. Document this in a comment block in `types/types.rs`. + +**Write the From/TryFrom bridges like Slab 2.** Concrete → wrapper enum: `impl From<&'t StructTT<'s, 't>> for KindT<'s, 't>` etc. Narrow → wide: `impl From> for KindT<'s, 't>`. Wide → narrow: `impl TryFrom> for ICitizenTT<'s, 't>` (owned, match-and-rewrap). Exactly like `From<&'t FunctionNameT> for INameT` and `TryFrom for IFunctionNameT` in names.rs. + +This decision is captured in `docs/reasoning/idt-typed-view-alternatives.md` — the sub-enum inline philosophy is common to both names and kinds. + +### Gotcha 2: `PrototypeT` derive(Hash) after Slab 2 + +Slab 2 made `IdT<'s, 't>` use custom `Hash`/`PartialEq`/`Eq` instead of derive. `PrototypeT<'s, 't>` has `id: IdT<'s, 't>` and `return_type: CoordT<'s, 't>`. Its `#[derive(Hash, PartialEq, Eq)]` should still work because Rust's `derive` generates an impl that calls the field's `Hash` — which is the custom `IdT` impl. But if it somehow fails to compile, add a manual Hash/Eq to `PrototypeT` that delegates to `self.id.hash(state); self.return_type.hash(state);`. + +### Gotcha 3: `IContainer` / `CitizenDefinitionTemplataT` — narrow enums, small DAGs + +These two enums are mini-unions that aren't used everywhere — they appear in specific spots like `CitizenDefinitionTemplataT` wraps `StructDefinitionTemplataT` or `InterfaceDefinitionTemplataT`. Read the Scala blocks carefully; the variant set is small (2-4 each). These are also inline-owned (not interned). + +### Gotcha 4: Heavy templatas hold `&'s FunctionA` / `&'s StructA` / etc. + +These reference higher-typing (scout-pass) output directly. `FunctionA`, `StructA`, `InterfaceA`, `ImplA` live in `src/higher_typing/ast.rs`. Use `&'s` — the same scout-arena lifetime that interned strings and runes use. Don't re-intern. + +Also, heavy templatas themselves are **allocated but not interned** per §1.5 — they live in the typing arena but the interner doesn't dedup them. In practice, the `ITemplataT` enum holds `&'t FunctionTemplataT` (arena ref), but that arena ref came from a simple `arena.alloc(FunctionTemplataT { ... })` call, not from an `intern()` call. + +You don't need to do anything special about this during Slab 3 — just define the types correctly and trust the interner to be a no-op for these families. The distinction matters in Slab 3+ when someone actually writes the arena-alloc calls. + +### Gotcha 5: Scala `ITemplataT[+T <: ITemplataType]` outer parameter is erased + +Scala's `ITemplataT` has an outer phantom type parameter tracking what kind of templata it is (`CoordTemplataType`, `KindTemplataType`, `MutabilityTemplataType`, etc.). In Rust this is **erased** — the variant tag + the `tyype` field on `PlaceholderTemplataT` carry the same information at runtime. Don't try to preserve the phantom parameter; the Rust enum is just `ITemplataT<'s, 't>`. + +Note: `PrototypeTemplataT[T <: IFunctionNameT]` in Scala is also a phantom — the Slab 2 post-refactor erased this too. `PrototypeT<'s, 't>` is monomorphic; `PrototypeTemplataT<'s, 't>` holds `prototype: &'t PrototypeT<'s, 't>` with no inner T. quest.md §6.6 mentions this T as "keep it" — that was the old design; the reasoning doc supersedes. + +### Gotcha 6: Don't write `impl XxxT { fn ... }` method bodies + +Like Slab 2, this is data-definition work only. Scala `case class` bodies with `vpass()`, `override def equals`, `def toString`, etc. are Slab 8+ work. If a Scala block has methods, leave them in the `/* */` and don't port them in Slab 3. The stubs that already exist (`impl<'s, 't> KindT<'s, 't> { fn expect_struct(&self) -> StructTT<'s, 't> { panic!(...) } }`) stay `panic!()` until later slabs. + +### Gotcha 7: Pre-commit hook on `/* */` blocks + +`.claude/hooks/check-scala-comments` does exact-match comparison between every `/* */` block and the Scala source. If you reformat or edit text inside a `/* */`, the commit is rejected. Same rule as Slab 2. + +## What "done" looks like + +- `cargo check --lib` passes with 0 errors. +- `KindT<'s, 't>` has 12 variants (6 primitives from Slab 1 + 6 non-primitives from Slab 3). No `_Phantom`. +- `ICitizenTT`, `ISubKindTT`, `ISuperKindTT` have real variants per the DAG and Gotcha 1 resolution. +- `ITemplataT<'s, 't>` has 19 variants. All payload structs (`CoordTemplataT`, `FunctionTemplataT`, etc. — ~16 of them) have Scala-parity fields. +- `IContainer<'s, 't>` and `CitizenDefinitionTemplataT<'s, 't>` have real variants. +- `KindValT`, `ITemplataValT`, `PrototypeValT`, `SignatureValT` exist in their home files with real shapes, not `PhantomData` stubs. `typing_interner.rs` imports them from their new locations. +- The four `intern_*` method bodies in `typing_interner.rs` stay `panic!()` — signatures updated to use the relocated Val types. +- Scala `/* */` blocks unchanged. +- Tag `slab-3-complete`. + +## When you're stuck + +- **"Lifetime error on `'t` unused"**: some stub structs need `PhantomData<&'t ()>` to anchor the lifetime. See Slab 2 Tier A/B for examples. +- **"cannot derive Hash because field X doesn't implement Hash"**: the field type's Hash derive is missing. Check the type; if it's a name or kind you own, add the derive; if it's something like `&'t FunctionA<'s>` where `FunctionA` doesn't have Hash, custom-impl Hash by doing pointer-hash (`std::ptr::hash(ptr, state)`) since `FunctionA` refs are scout-arena-interned and thus have pointer identity. +- **"Scala extends `with IInterning` or `with Equatable` or `with IInstantiationBoundEquivalent`"**: these are marker traits in Scala, not real sub-traits. They don't map to any Rust enum variant. Ignore them. +- **"I don't know whether `KindValT::Struct` should hold `StructTT` by value or `&'t StructTT`"**: quest.md §6.5's Rust block answers this — the canonical enum holds it by value; the Val mirrors. But see Gotcha 1 first. +- **"Something in env/*.rs is missing and I need it"**: Slab 4 hasn't happened yet. Use whatever existing placeholder (`IEnvironmentT` stub, `IInDenizenEnvironmentT` stub) is already there. Don't try to build Slab 4 types in Slab 3. +- **Anywhere you're tempted to modify `names/names.rs`**: don't. Slab 2 is frozen. If you think a name type needs changing, the design shifted and you should ask the senior. + +## Where to file questions + +- **Design** (Gotcha 1 especially): ask the senior first. The inline-vs-interned question for KindT sub-enums has real downstream implications. +- **Scala semantics**: the `/* */` block is the spec. If that's ambiguous, the senior has access to the external Scala repo. +- **Hook rejections**: read the diff the hook prints. Usually it's you accidentally editing inside a `/* */` block. + +## Final advice + +Like Slab 2, this is data-definition grunt work. It's smaller (~1000 lines scope vs 2600) and simpler (tiny DAG for kind sub-enums), but the IDEPFL Val work is fiddly — especially `PrototypeValT` and `SignatureValT` which need `'tmp` lifetimes because they transitively contain IdT's init_steps slice. Follow the Slab 2 Step 6 template: `IdValT<'s, 't, 'tmp>` is your reference. + +Get the Gotcha 1 answer before writing code.

See Gotcha 1 below for why. +2. `TL-HANDOFF.md` at the repo root — overrides section captures the `'t`-not-`'s` correction and Slab-3 state you need to respect. +3. `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md` — records the arena design you're building **and** the deferred post-migration design. Explains why Slab 4 is arena-based, what that costs, what future work is scheduled. The "Chosen (during migration)" section is the spec for this slab. +4. `.claude/rules/postparser/IDEPFL-postparser-interning.md` — the dual-enum value/reference pattern. The interner bodies you're writing use it (see Gotcha 2 for the live reference impl in `scout_arena.rs`). +5. `FrontendRust/docs/migration/handoff-slab-3.md` — sets conventions you'll reuse (inline-wrapper philosophy, `From`/`TryFrom` bridges, `/* scala */` block rules). +6. `FrontendRust/docs/reasoning/idt-typed-view-alternatives.md` — already-established: `IdT`, `PrototypeT`, `SignatureT` are monomorphic. Several Scala env types (`PackageEnvironmentT[+T]`, `CitizenEnvironmentT[+T,+Y]`, `GeneralEnvironmentT[+T]`, `BuildingFunctionEnvironmentWithClosuredsT.id: IdT[IFunctionTemplateNameT]`) are phantom-generic in Scala; erase those generics in Rust. Every Scala `IdT[…]` becomes the monomorphic `IdT<'s, 't>` on the Rust side; call sites pattern-match `id.local_name` to narrow. +7. This doc. + +**Two senior-already-decided items to know up front** (don't re-litigate): + +- **Envs live in `'t` arena, not `'s`.** See Gotcha 1. Quest.md §3.1 is wrong about this. +- **No `Rc`, no side table, no interior mutability.** Builder+freeze pattern per quest.md §3.3 applies. The deferred side-tables-of-`Rc` design lives in the reasoning doc above and is post-Slab-8 work. Slab 4 is intentionally arena-based. + +You shouldn't need to read the Scala source externally — every Scala `case class` / sealed trait is already embedded inline in the `/* ... */` blocks in the env/ files. If the block is ambiguous, ask; don't guess. + +## The big picture: why Slab 4 exists + +Environments are the runtime store for name-and-type resolution during typing. When you write `let x = foo(5)` inside a function body, the compiler walks up the env chain looking for what `foo` resolves to — is it a function template? a local variable? an imported templata? The env chain has structure: a function body's `NodeEnvironmentT` inherits from a `FunctionEnvironmentT`, which inherits from a `CitizenEnvironmentT` or `PackageEnvironmentT`, etc. + +In Scala, envs are plain case classes and a `NodeEnvironmentBox` mutable wrapper. In Rust we're using arena-allocated envs (`&'t FooEnvironmentT<'s, 't>`) with a builder-freeze pattern for mutation. This matches the storage philosophy of Slabs 1-3 (names, kinds, templatas) — everything lives in the typing arena, everything is referenced by `&'t`. + +Slab 4 is bigger than Slab 2/3 because: + +1. **Nine env variants**, each a real struct with 4–10 fields. Scala env code has more logic mixed with data than the name/kind/templata types did. +2. **`TemplatasStoreT`** is the first "map-like" arena structure — slice-of-pairs pattern per AASSNCMCX. You're working through the arena-slice idiom in earnest for the first time. +3. **Builder types** — each env kind that mutates during construction gets a matching `*Builder` stack struct with heap `Vec`s. You're introducing a second type family per env variant. +4. **`TypingInterner` gains real bodies.** Slabs 2-3 left `intern_id` / `intern_prototype` / `intern_signature` as `panic!()`. Slab 4 implements them (plus ~60 concrete-name intern methods and ~12 concrete payload intern methods for StructTT/InterfaceTT/KindTemplataT/etc.). Envs can't be constructed without real interning, so this is the first slab that lights up the interner. +5. **`GlobalEnvironmentT`** is a new type introduced here (not just an expand-stub-into-fields job). Every env holds `&'t GlobalEnvironmentT<'s, 't>` as a back-ref. +6. **Two parallel enums** — `IEnvironmentT` (9 variants) and `IInDenizenEnvironmentT` (6-variant subset). Both wrap the same `&'t FooEnvironmentT` payloads. You need `From`/`TryFrom` bridges between them. +7. **Variable types** (`IVariableT`, `ILocalVariableT`, `AddressibleLocalVariableT`, `ReferenceLocalVariableT`, `AddressibleClosureVariableT`, `ReferenceClosureVariableT`) need real definitions.

A struct with lifetime `'s` can only hold `&'x T` where `'x: 's`. Since `'s: 't` (scout outlives typing), `'t: 's` is **false**, so a `'s`-allocated env cannot hold a `&'t` ref. The borrow checker will reject this. + +**Fix:** envs go in the typing arena `'t`. Every `&'s FooEnvironmentT<'s, 't>` in quest.md Part 3 becomes `&'t FooEnvironmentT<'s, 't>`. Builder `build_in` methods take `&TypingBump<'t>` (or whatever the typing-arena handle is, following Slab 0's substrate), not `&ScoutArena<'s>`. + +Full write-up: `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md` § "Arena choice".

See `scout_arena.rs::intern_name` (L245) for the shape. +2. `intern_id(val: IdValT<'s,'t,'tmp>) -> &'t IdT<'s,'t>` — `'tmp`-borrowed `init_steps` slice (@DSAUIMZ); promote on miss. +3. `intern_prototype(val: PrototypeValT<'s,'t,'tmp>) -> &'t PrototypeT<'s,'t>`. +4. `intern_signature(val: SignatureValT<'s,'t,'tmp>) -> &'t SignatureT<'s,'t>`. +5. `intern_kind_payload(val: InternedKindPayloadValT<'s,'t>) -> InternedKindPayloadT<'s,'t>` — dispatches across 6 Kind payload concretes. +6. `intern_templata_payload(val: InternedTemplataPayloadValT<'s,'t,'tmp>) -> InternedTemplataPayloadT<'s,'t>` — dispatches across 6 interned templata payload concretes. + +**~75 per-concrete convenience wrappers** — mechanical, each ~5 lines: wrap input into the family Val, dispatch through `intern_`, unwrap to the specific concrete. Same shape as scout's `intern_struct_declaration_name` (L231-236). Examples: + +```rust +pub fn intern_function_name<'tmp>(&self, val: FunctionNameValT<'s,'t,'tmp>) -> &'t FunctionNameT<'s,'t> { + match self.intern_name(INameValT::FunctionName(val)) { + INameT::Function(r) => r, + _ => unreachable!(), + } +} +pub fn intern_struct_tt(&self, val: StructTT<'s,'t>) -> &'t StructTT<'s,'t> { + match self.intern_kind_payload(InternedKindPayloadValT::StructTT(val)) { + InternedKindPayloadT::StructTT(r) => r, + _ => unreachable!(), + } +} +// ... one per concrete: ~60 name + 6 Kind payload + 6 templata payload + 3 top-level (Id/Prototype/Signature) = ~75 wrappers. +``` + +These wrappers are what downstream sub-compiler code calls. Consider a `macro_rules!` helper (`impl_intern_wrapper!(method_name, family, variant, ValT, CanonicalT)`) to reduce boilerplate — the `intern_function_name` shape is identical across ~60 name wrappers. Slab 2 may have similar macros for `From`/`TryFrom` bridges worth reusing as a pattern. + +**`TypingInterner` needs a second lifetime parameter.** The current stub is `TypingInterner<'t>(PhantomData)` — *that's insufficient once you add real bodies.* Interned values carry both lifetimes in their types (e.g. `FunctionNameT<'s, 't>` has `human_name: StrI<'s>`; `IdT<'s, 't>` has `init_steps: &'t [INameT<'s, 't>]`). The interner's `Inner<'s, 't>` holds HashMaps keyed on those types, so the outer type becomes `TypingInterner<'s, 't>`. This ripples through: + +- `Compiler<'s, 'ctx, 't>.typing_interner: &'ctx TypingInterner<'s, 't>` (currently `&'ctx TypingInterner<'t>`). +- Every sub-compiler method that takes `&TypingInterner<'t>` or holds one. +- Every external `TypingInterner::new` call site. + +Budget it: probably a mechanical sed across ~10-30 sites. + +**One HashMap per sealed-trait family, not per concrete.** Scout's `ScoutArena` (see `src/scout_arena.rs` L62-L65) has three HashMaps — `name_val_to_ref`, `rune_val_to_ref`, `imprecise_name_val_to_ref` — each keyed on a tagged-union `*ValS` enum that holds one variant per concrete in that sealed-trait family. Per-concrete intern methods (`intern_struct_declaration_name`, etc.) wrap into the union, dispatch through the single map, and unwrap on return. Typing uses the same pattern.

At builder freeze time: for each imprecise name, allocate a slice of its entries via `bump.alloc_slice_copy(&entries_for_name)`, collect `(&'s IImpreciseNameS, &'t [IEnvEntryT])` tuples into an outer `Vec`, freeze outer as `&'t [(…)]`.

For the live ones: swap the param type to `&mut NodeEnvironmentBuilder<'s, 't>` / `&mut FunctionEnvironmentBuilder<'s, 't>` where the method actually uses the box's mutation API; otherwise make the whole body `panic!("Unimplemented: Slab 8 signature rewrite")` and let Slab 8 figure out the exact shape. + +**Hot tip:** `rg -n "NodeEnvironmentBox|FunctionEnvironmentBoxT|IDenizenEnvironmentBoxT" src/typing/ --type rust` before you start, to see the full call-site list. + +### Gotcha 5: `GlobalEnvironmentT` definition + +Scala `GlobalEnvironment` has macro fields that in Rust live on `Compiler` instead (per the god-struct refactor — see `FrontendRust/docs/migration/handoff-god-struct-progress.md`).

No `Rc`, no cycles (see the reasoning doc's "cycles" section). + +### Gotcha 6: `IEnvEntryT` is an inline 5-variant enum + +Per senior's answer (#3): + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub enum IEnvEntryT<'s, 't> { + Function(&'s FunctionA<'s>), + Struct(&'s StructA<'s>), + Interface(&'s InterfaceA<'s>), + Impl(&'s ImplA<'s>), + Templata(ITemplataT<'s, 't>), +} +``` + +No separate `FunctionEnvEntry` / `StructEnvEntry` / etc. structs — delete those five stubs in `i_env_entry.rs`. The scout refs (`&'s FunctionA` etc.) are the entire variant payload; `ITemplataT` is already the inline Slab-3 wrapper. + +Size: 1 byte tag + 16-byte `ITemplataT` variant (the wide case) → ~24 bytes. The `&'s _` variants are 1 tag + 8-byte ref = ~16 bytes, but the enum sizes to its biggest variant. + +Not interned. Not `&'t`-boxed. Lives inline in `TemplatasStoreT.name_to_entry: &'t [(INameT, IEnvEntryT)]`. + +The Scala `/* */` blocks for `FunctionEnvEntry`, `ImplEnvEntry`, `StructEnvEntry`, `InterfaceEnvEntry`, `TemplataEnvEntry` stay in the file next to the new enum, not next to individual Rust stubs (since the stubs are deleted). The pre-commit hook only cares that `/* */` blocks aren't edited, not that they have a Rust sibling — see Gotcha 7. + +### Gotcha 7: Pre-commit hook on `/* */` blocks + +`.claude/hooks/check-scala-comments` does **exact-match** comparison on every `/* ... */` Scala block. Any edit inside rejects the commit. Rules for this slab: + +- **Don't edit inside a `/* */` block** — the text between `/*` and `*/` is frozen. +- **You can delete a Rust stub above a `/* */` block** as long as the `/* */` stays byte-for-byte unchanged. The hook only checks the block content. (This is how you'll handle `NodeEnvironmentBox` deletion, `FunctionEnvEntry` deletion, etc.) +- **You can reorder `/* */` blocks** within a file if needed, as long as each block's content stays identical. Rarely needed, but possible. +- **You can add a new Rust definition between two existing `/* */` blocks** (e.g. a builder struct that has no direct Scala counterpart — put it before the `/* */` block of its frozen-form companion, with a `// (no scala counterpart — builder for NodeEnvironmentT)` note). + +Same rule as Slabs 2/3. You won't be running `git commit` yourself (the human does that after review), but the hook still defines what edits are legal — if you accidentally change whitespace inside a `/* */` block, it'll show up at the human's commit-time and bounce back to you. Treat the hook as an always-on invariant, not a commit-time check. + +### Gotcha 8: Don't write `impl EnvironmentT { fn … }` method bodies + +Data definitions only. Scala `case class` bodies with `override def equals`, `def addEntry(interner, name, entry): FooEnvironmentT = …`, `def rootCompilingDenizenEnv`, `def lookupWithNameInner` etc. are Slab 8+ work. Leave them in the `/* */` and don't port them in Slab 4. + +Stubs that already exist in sub-compiler files (like `impl Compiler { fn lookup_nearest_with_name(...) { panic!() } }`) stay `panic!()` until the signature-rewrite slab. + +**Exception:** you may need `impl` blocks for a few mechanical things: +1. **Builder `build_in` methods** — real implementations, because the builders don't exist in Scala and Slab 4 has to provide them. +2. **`From`/`TryFrom` bridges** — real implementations, per Slab 2/3 convention. +3. **Trivial projection methods** (like `pub fn id(&self) -> IdT<'s, 't> { self.id }`) — OK if directly needed to make another Slab 4 definition type-check. Otherwise wait for Slab 8. + +If in doubt, prefer `panic!()` bodies and let Slab 8 fill them. + +### Gotcha 9: `FunctionEnvironmentT.parent_env` is inclusive of Package + +Scala `FunctionEnvironmentT.parentEnv: IEnvironmentT` (wide). `FunctionEnvironmentT.rootCompilingDenizenEnv` matches on `parentEnv` and `vwat()`s on `PackageEnvironmentT` — so `parentEnv` can be `PackageEnvironmentT` at runtime even though the logic assumes it won't be. Keep `parent_env: IEnvironmentT<'s, 't>` as the Scala type says; the runtime guarantees aren't your concern during data translation. + +### Gotcha 10: Slab 3 patched env stubs with derives + +Slab 3 patched `IEnvironmentT` / `IInDenizenEnvironmentT` stubs with `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` so `OverloadSetT` could derive `Hash`/`Eq` (it contains an env ref). When you replace those stubs with real enums, **keep the derives identical** — `Copy, Clone, PartialEq, Eq, Hash, Debug`. If you drop any, `OverloadSetT` stops compiling and Slab 3 breaks retroactively. + +Spot check: after replacing, `cargo check --lib` should not complain about `OverloadSetT` — if it does, you lost a derive. + +### Gotcha 11: Slab-3 heavy templatas reference envs as `&'s`; flip them to `&'t` + +When Slab 3 shipped, the env stubs still implied `'s` arena allocation (quest.md §3.1's original spec). The code in `src/typing/templata/templata.rs` and `src/typing/types/types.rs` thus landed with `&'s IEnvironmentT<'s, 't>` / `&'s IInDenizenEnvironmentT<'s, 't>` refs in five places. Slab 4's `'t` arena correction (Gotcha 1) makes these stale. + +Five sites to flip `&'s` → `&'t`: +- `FunctionTemplataT.outer_env: &'s IEnvironmentT<'s, 't>` → `&'t` +- `StructDefinitionTemplataT.declaring_env: &'s IEnvironmentT<'s, 't>` → `&'t` +- `InterfaceDefinitionTemplataT.declaring_env: &'s IEnvironmentT<'s, 't>` → `&'t` +- `ImplDefinitionTemplataT.env: &'s IEnvironmentT<'s, 't>` → `&'t` +- `OverloadSetT.env: &'s IInDenizenEnvironmentT<'s, 't>` → `&'t` + +Do this in **Step 5.5** — after the 9 env variants exist (Step 5) and before the interner bodies (Step 6). The step plan has a dedicated slot for it. Verify with `cargo check --lib`. + +Other field-type references to env types in sub-compiler method signatures (e.g. `&IInDenizenEnvironmentT<'s, 't>` in `edge_compiler.rs`) are elided-lifetime borrows — those stay as-is since they don't pin to an arena. + +### Gotcha 12: `LocationInFunctionEnvironmentT.path: Vec` is pre-existing debt + +`LocationInFunctionEnvironmentT<'s>` in `ast/ast.rs` has `path: Vec`. That's an AASSNCMCX-nonconforming `Vec` inside a type that lives conceptually in the `'t` arena. Two problems: (a) it violates the shield; (b) if someone later arena-allocates a struct containing this, bumpalo won't run the `Vec`'s destructor → leak. **Not Slab 4's problem.** You'll use `LocationInFunctionEnvironmentT` as-is (`NodeEnvironmentT` has `life: LocationInFunctionEnvironmentT<'s>`). If it triggers shield complaints during review, point at this gotcha and move on. Fix is probably "change to `&'t [i32]`" in a future cleanup slab. + +### Gotcha 13: env `Hash`/`PartialEq` must be id-based, not derived + +Scala env case classes override `equals` to compare *only the id* (and override `hashCode` to cache `id.hashCode`). Example (Scala `FunctionEnvironmentT`): + +```scala +val hash = runtime.ScalaRunTime._hashCode(id); +override def hashCode(): Int = hash; +override def equals(obj: Any): Boolean = { + if (!obj.isInstanceOf[IInDenizenEnvironmentT]) return false + id.equals(obj.asInstanceOf[IInDenizenEnvironmentT].id) +} +``` + +`#[derive(PartialEq, Eq, Hash)]` on the Rust struct would walk every field — including `TemplatasStoreT`'s two slices — which (a) is slow, and (b) diverges from Scala's id-based identity. Two envs with the same id but temporarily different templatas should compare equal; the derived version wouldn't. + +**Do this for every env that has a Scala `override def equals`:** `PackageEnvironmentT`, `CitizenEnvironmentT`, `ExportEnvironmentT`, `ExternEnvironmentT`, `FunctionEnvironmentT`, `BuildingFunctionEnvironmentWithClosuredsT`, `BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT`. Manual impl: + +```rust +impl<'s, 't> PartialEq for FunctionEnvironmentT<'s, 't> { + fn eq(&self, other: &Self) -> bool { self.id == other.id } +} +impl<'s, 't> Eq for FunctionEnvironmentT<'s, 't> {} +impl<'s, 't> std::hash::Hash for FunctionEnvironmentT<'s, 't> { + fn hash(&self, state: &mut H) { self.id.hash(state); } +} +``` + +**`NodeEnvironmentT` is different** — Scala hashes `id.hashCode ^ life.hashCode` and compares `(id, life)`. So: +```rust +impl<'s, 't> PartialEq for NodeEnvironmentT<'s, 't> { + fn eq(&self, other: &Self) -> bool { + self.parent_function_env.id == other.parent_function_env.id + && self.life == other.life + } +} +// Hash analogously. +``` + +**`GeneralEnvironmentT`** has `override def equals = vcurious()` / `override def hashCode = vcurious()` — in Rust that's `panic!("vcurious")` in a manual impl. Match Scala; don't derive. + +Keep `Debug` derived. Keep the struct-level `#[derive]` block but remove `PartialEq, Eq, Hash` from it, then add the manual impls separately. + +### Gotcha 14: `where 's: 't` on every env struct + +The current `PhantomData` stubs implicitly anchor `'s` and `'t` via `PhantomData<(&'s (), &'t ())>`. When you replace them with real fields that hold `&'t` data, you need the explicit lifetime bound. Otherwise the compiler errors with "`'s` may not live long enough" on any field of the form `&'t SomethingWith_s<'s>`: + +```rust +pub struct FunctionEnvironmentT<'s, 't> +where 's: 't, +{ + pub global_env: &'t GlobalEnvironmentT<'s, 't>, + // ... etc +} +``` + +Put `where 's: 't` on every env struct, every builder, `GlobalEnvironmentT`, `TemplatasStoreT`, `TemplatasStoreBuilder`, `IEnvEntryT`, `IVariableT`, `ILocalVariableT`, and the 4 concrete variable structs. Slab 2/3 did the same for their arena-allocated types. + +`IEnvironmentT` / `IInDenizenEnvironmentT` (the wrapper enums) already work because their variants hold `&'t` refs without needing an explicit bound — Rust infers it from the usage. But adding `where 's: 't` to them too doesn't hurt and keeps the file uniform. + +### Gotcha 15: `i_env_entry.rs` stays; only the type gets a `T` suffix + +Scala's type is `IEnvEntry` (no `T`); its source file is `IEnvEntry.scala`; the Rust stub file is `src/typing/env/i_env_entry.rs` (matching the Scala filename). Slab 4 adds the `T` suffix to the Rust *type* — `IEnvEntry` → `IEnvEntryT` — for consistency with the rest of the typing pass (every other typing-pass type in Rust carries `T`). **Don't rename the file.** Rust filenames track the Scala-source filename, not the Rust-type name; that's why `function_environment_t.rs` does have `_t` (Scala source is `FunctionEnvironmentT.scala`) but `i_env_entry.rs` doesn't. + +### Gotcha 16: `IVariableT` / `ILocalVariableT` DAG and variants + +Scala has a small DAG: + +```scala +sealed trait IVariableT { + def name: IVarNameT + def variability: VariabilityT + def coord: CoordT +} +sealed trait ILocalVariableT extends IVariableT { + // inherits the same fields +} + +case class AddressibleLocalVariableT(name, variability, coord) extends ILocalVariableT +case class ReferenceLocalVariableT(name, variability, coord) extends ILocalVariableT +case class AddressibleClosureVariableT(name, closuredVarsStructType: StructTT, variability, coord) extends IVariableT // NOT ILocal +case class ReferenceClosureVariableT(name, closuredVarsStructType: StructTT, variability, coord) extends IVariableT // NOT ILocal +``` + +Apply the Slab 2 DAG rule: each concrete variant appears in each sub-enum it transitively belongs to. + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub enum IVariableT<'s, 't> { + AddressibleLocal(AddressibleLocalVariableT<'s, 't>), + ReferenceLocal(ReferenceLocalVariableT<'s, 't>), + AddressibleClosure(AddressibleClosureVariableT<'s, 't>), + ReferenceClosure(ReferenceClosureVariableT<'s, 't>), +} + +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub enum ILocalVariableT<'s, 't> { + Addressible(AddressibleLocalVariableT<'s, 't>), + Reference(ReferenceLocalVariableT<'s, 't>), +} +``` + +Variants hold the concrete structs **by value**, not `&'t`. These structs are small (~40 bytes with `coord: CoordT` inline) and not arena-interned — they're analogous to Scala `ILocalVariableT` being a plain case class, not a pointer-indirection. If sizing becomes a problem later, revisit; for Slab 4, inline. + +Concrete shapes to match Scala: + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub struct AddressibleLocalVariableT<'s, 't> { + pub name: IVarNameT<'s, 't>, + pub variability: VariabilityT, + pub coord: CoordT<'s, 't>, +} + +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub struct ReferenceLocalVariableT<'s, 't> { + pub name: IVarNameT<'s, 't>, + pub variability: VariabilityT, + pub coord: CoordT<'s, 't>, +} + +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub struct AddressibleClosureVariableT<'s, 't> { + pub name: IVarNameT<'s, 't>, + pub closured_vars_struct_type: &'t StructTT<'s, 't>, // Slab 3 interned payload + pub variability: VariabilityT, + pub coord: CoordT<'s, 't>, +} + +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub struct ReferenceClosureVariableT<'s, 't> { + pub name: IVarNameT<'s, 't>, + pub closured_vars_struct_type: &'t StructTT<'s, 't>, + pub variability: VariabilityT, + pub coord: CoordT<'s, 't>, +} +``` + +Note `closured_vars_struct_type: &'t StructTT<'s, 't>` — Scala's `closuredVarsStructType: StructTT` maps to a `&'t` ref because `StructTT` is an interned Slab-3 Kind payload (arena-allocated, accessed by pointer identity), not a by-value Copy type. + +Write `From`/`TryFrom` bridges both directions: concrete → `ILocalVariableT`, concrete → `IVariableT`, `ILocalVariableT` → `IVariableT`, `TryFrom` for each concrete. Slab 2 style. + +## Builder types + +One `*Builder` per env variant. Naming: `NodeEnvironmentBuilder<'s, 't>`, `FunctionEnvironmentBuilder<'s, 't>`, `CitizenEnvironmentBuilder<'s, 't>`, etc. Lives next to the env struct in the same file. + +**All 9 envs need builders** because all 9 contain a `TemplatasStoreT`, and `TemplatasStoreT` is itself built via `TemplatasStoreBuilder` (heap `Vec` + heap `HashMap`, frozen into `'t` slices on `build_in`). Envs that also carry other incrementally-built collections (`NodeEnvironmentT.declared_locals`, `FunctionEnvironmentT.closured_locals`, etc.) use the builder for those too. + +`TemplatasStoreBuilder<'s, 't>` is the base builder; env-specific builders compose it. + +Shape per quest.md §3.3: + +```rust +pub struct NodeEnvironmentBuilder<'s, 't> { + pub parent_function_env: &'t FunctionEnvironmentT<'s, 't>, + pub parent_node_env: Option<&'t NodeEnvironmentT<'s, 't>>, + pub node: &'s IExpressionSE<'s>, + pub life: LocationInFunctionEnvironmentT<'s>, + pub templatas_builder: TemplatasStoreBuilder<'s, 't>, + pub declared_locals: Vec>, + pub unstackified_locals: Vec>, + pub restackified_locals: Vec>, + pub default_region: RegionT, +} + +impl<'s, 't> NodeEnvironmentBuilder<'s, 't> { + pub fn build_in(self, interner: &TypingInterner<'t>) -> &'t NodeEnvironmentT<'s, 't> { + let templatas = self.templatas_builder.build_in(interner); + let declared_locals = interner.bump().alloc_slice_copy(&self.declared_locals); + let unstackified_locals = interner.bump().alloc_slice_copy(&self.unstackified_locals); + let restackified_locals = interner.bump().alloc_slice_copy(&self.restackified_locals); + interner.bump().alloc(NodeEnvironmentT { + parent_function_env: self.parent_function_env, + parent_node_env: self.parent_node_env, + node: self.node, + life: self.life, + templatas, + declared_locals, + unstackified_locals, + restackified_locals, + default_region: self.default_region, + }) + } +} +``` + +Note: `interner.bump()` — add a getter on `TypingInterner` returning `&'t Bump` (or the arena handle you use). Call sites freezing non-interned data need it. Alternatively, pass `&'t Bump` as a separate `build_in` param; pick what minimizes noise. + +`TemplatasStoreBuilder<'s, 't>` is its own builder type with `name_to_entry: Vec<(INameT, IEnvEntryT)>` and `imprecise_to_entries: HashMap<&'s IImpreciseNameS<'s>, Vec>` (heap HashMap during construction, frozen to nested slices on `build_in`). + +**Child-scope API (per senior's answer #6):** `NodeEnvironmentT::make_child` on the frozen env returns a fresh `NodeEnvironmentBuilder` (not `&mut NodeEnvironmentT` — that's infeasible on `&'t`-allocated envs, as the reasoning doc notes). Scala's `makeChild` returns a new case class; Rust returns a builder. + +## Step-by-step plan + +### Step 1: Confirm starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-4.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-4.txt +``` + +Must print `0`. If it doesn't, stop and ask the senior. The project sets `#![allow(unused_variables, unused_imports)]`, so don't rely on warning counts. + +### Step 2: Stub real-interner Inner skeleton + flip to `TypingInterner<'s, 't>` + +Before writing any env data, stand up the `TypingInterner` internal skeleton (empty HashMaps, bump, `RefCell`) and add the second lifetime parameter. + +Concrete changes: + +1. **Rewrite `typing_interner.rs`** to have: + ```rust + pub struct TypingInterner<'s, 't> { + bump: &'t Bump, + inner: RefCell>, + } + struct Inner<'s, 't> { + // Will be filled in Step 6 — for now, just one or two HashMap fields as placeholders + // so the struct actually carries 's. Use _phantom if you can't think of one. + _phantom: std::marker::PhantomData<(&'s (), &'t ())>, + } + impl<'s, 't> TypingInterner<'s, 't> { + pub fn new(bump: &'t Bump) -> Self { /* ... */ } + pub fn alloc(&self, val: T) -> &'t mut T { self.bump.alloc(val) } + pub fn alloc_slice_copy(&self, src: &[T]) -> &'t [T] { + self.bump.alloc_slice_copy(src) + } + // intern_id / intern_prototype / intern_signature stay as panic!() stubs; + // signatures updated to use <'s, 't> instead of <'t>. + } + ``` +2. **Flip `Compiler<'s, 'ctx, 't>.typing_interner`** from `&'ctx TypingInterner<'t>` to `&'ctx TypingInterner<'s, 't>`. Update `Compiler::new`'s parameter type accordingly. Find the driver/top-level callers: `rg -n "TypingInterner<'t>|TypingInterner::new" src/` — flip every hit to `TypingInterner<'s, 't>`. The driver pattern will look like: + ```rust + let typing_bump = Bump::new(); + let typing_interner = TypingInterner::new(&typing_bump); + let compiler = Compiler::new(&scout_arena, &typing_interner, &keywords, &opts); + ``` +3. **Every sub-compiler method that references `&TypingInterner<'t>`** gets flipped to `&TypingInterner<'s, 't>`. There are ~10-30 sites; most are in `src/typing/typing_interner.rs` references across the sub-compiler files. Pure mechanical sed; `cargo check --lib` catches missed ones. +4. `cargo check --lib` — should pass. You've only changed signatures; the method bodies still panic. + +Don't wire intern method bodies yet (Step 6). Don't touch env data yet (Steps 3-5). + +### Step 3: Variable types first (smallest unit of work) + +Fill `IVariableT`, `ILocalVariableT`, and the four concrete variable structs in `env/function_environment_t.rs` per Gotcha 16. Write `From`/`TryFrom` bridges. This unblocks expression AST downstream uses. + +`cargo check --lib`. Fix downstream compile errors at reference sites — most will be "match arms over `ILocalVariableT` now have two real variants." Wherever a match is incomplete and the body is a sub-compiler method, add a `_ => panic!("Unimplemented: Slab 8")` arm for Slab 8 to fill. + +### Step 4: `IEnvEntryT`, `TemplatasStoreT`, `GlobalEnvironmentT` + +Fill these three in dependency order: +1. `IEnvEntryT` (Gotcha 6) — inline 5-variant enum in `env/i_env_entry.rs`. Delete the five individual struct stubs. Keep their Scala `/* */` blocks. +2. `TemplatasStoreT` + `TemplatasStoreBuilder` (Gotcha 3) — in `env/environment.rs`. Note the builder's heap `HashMap<&'s IImpreciseNameS, Vec>` for imprecise entries, frozen to nested slices at `build_in`. +3. `GlobalEnvironmentT` (Gotcha 5) — in `env/environment.rs`. No builder needed at this slab level; it's constructed once at the start of the typing pass (actual construction is Slab 7 territory when `run_typing_pass` is written). + +`cargo check --lib`. + +### Step 5: Fill the 9 env variants + their builders + +Order for smallest blast radius: +1. `PackageEnvironmentT` (no parent, simplest). +2. `CitizenEnvironmentT`, `ExportEnvironmentT`, `ExternEnvironmentT` (parent is `&'t PackageEnvironmentT` for Export/Extern, `IEnvironmentT` for Citizen — all simple). +3. `GeneralEnvironmentT`. +4. `BuildingFunctionEnvironmentWithClosuredsT`, `BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT`. +5. `FunctionEnvironmentT` + `FunctionEnvironmentBuilder`. +6. `NodeEnvironmentT` + `NodeEnvironmentBuilder`. + +After each, `cargo check --lib`. Fix downstream errors conservatively with `panic!("Unimplemented: Slab 8")` where body logic would be needed. + +Write `From`/`TryFrom` bridges for `IEnvironmentT` ↔ `IInDenizenEnvironmentT` and concrete → wrapper after all 9 env structs exist. + +**Delete** `NodeEnvironmentBox`, `FunctionEnvironmentBoxT`, and the `IDenizenEnvironmentBoxT` trait stub per Gotcha 4. Fix reference sites. + +### Step 5.5: Flip Slab-3 heavy-templata env refs from `&'s` to `&'t` + +Per Gotcha 11: change the 5 heavy-templata/OverloadSet env-ref field types. Carve-out from the "don't touch" list. + +1. `FunctionTemplataT.outer_env: &'s IEnvironmentT<'s, 't>` → `&'t` +2. `StructDefinitionTemplataT.declaring_env: &'s IEnvironmentT<'s, 't>` → `&'t` +3. `InterfaceDefinitionTemplataT.declaring_env: &'s IEnvironmentT<'s, 't>` → `&'t` +4. `ImplDefinitionTemplataT.env: &'s IEnvironmentT<'s, 't>` → `&'t` +5. `OverloadSetT.env: &'s IInDenizenEnvironmentT<'s, 't>` → `&'t` + +Each flip will cascade through construction sites. Use `panic!("Unimplemented: Slab 8")` to short-circuit any sub-compiler body that breaks; goal is `cargo check --lib` clean. + +Also confirm the Slab-3 custom `PartialEq`/`Eq`/`Hash` impls on heavy templatas (`ptr::eq` on the env ref) still type-check with the lifetime flipped — they should, because `ptr::eq` doesn't care which arena the ref points into. Sanity-check with `cargo check --lib`. + +### Step 6: Fill `TypingInterner` bodies + +Largest chunk of Slab 4 — probably ~800-1500 lines. Order matters (family-level before per-concrete wrappers, because the wrappers dispatch through the family-level methods): + +1. **Create the 3 new union Val enums** per Gotcha 2: `INameValT<'s,'t,'tmp>` in `names/names.rs`, `InternedKindPayloadValT<'s,'t>` + `InternedKindPayloadT<'s,'t>` in `types/types.rs`, `InternedTemplataPayloadValT<'s,'t,'tmp>` + `InternedTemplataPayloadT<'s,'t>` in `templata/templata.rs`. Derives: `Copy, Clone, Hash, PartialEq, Eq, Debug`. For the `'tmp`-bearing ones, write manual `Hash`/`PartialEq` impls if derive misbehaves across `'tmp` variants (should work given the per-variant Vals already derive cleanly; derive first, manual only if it fails). + +2. **Add the 6 HashMap fields to `Inner<'s, 't>`**, replacing the Step 2 placeholder `_phantom`. Use `hashbrown::HashMap` for the `'tmp`-bearing families, `std::HashMap` for `InternedKindPayloadValT` (no slices). + +3. **Write the 6 `intern_` methods** — the real work. Each does `inner.borrow().map.get(&val)` → if present, return cloned canonical; if absent, `alloc__canonical` (match on Val variant, arena-alloc the concrete, wrap in the canonical-enum variant), then `inner.borrow_mut().map.insert(val, canonical)`. Mirror `scout_arena.rs::intern_rune` (L329) and `intern_name` (L245). + +4. **Write `intern_id` / `intern_prototype` / `intern_signature`** — these are top-level singletons (not family-dispatched), same shape as the family methods but simpler since there's only one Val type per map. + +5. **Write the ~75 per-concrete wrapper methods** — all mechanical wrap/dispatch/unwrap. Consider a `macro_rules!` helper here; Slab 2 may have similar macros for `From`/`TryFrom` patterns worth reusing. + +`cargo check --lib` after each sub-step. Errors at this point are typically query-wrapper type mismatches — re-read the scout_arena.rs `RuneValQuery` pattern until the query/canonical shapes line up. + +`cargo check --lib` after each family. Compile errors at this point are typically "query wrapper type mismatch" — re-read the scout_arena.rs pattern until the query/canonical shapes line up. + +### Step 7: Wire builder `build_in` methods + +With the interner lit up, finish each builder's `build_in` impl so they actually allocate into the arena. Before Step 6 they could `panic!()`; now they should work. + +`cargo check --lib`. Compile errors downstream here are typically "this sub-compiler call site used to construct a `PhantomData` env stub; now needs a real builder." Replace with `panic!("Unimplemented: Slab 8 — construct real builder")` and move on. + +### Step 8: Verify and hand off + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-4.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-4.txt # must be 0 +grep -rn "_Phantom\|PhantomData<(&'s (), &'t ())>" FrontendRust/src/typing/env/ +# ^ should show few or zero hits — only the handful of genuinely lifetime-anchoring +# PhantomData fields (e.g. on `LocationInFunctionEnvironmentT`), not placeholder stubs. +grep -rn "PhantomData" FrontendRust/src/typing/typing_interner.rs +# ^ should show zero hits — TypingInterner is now a real struct with Bump + HashMap. +``` + +**Never commit.

If you need a local savepoint mid-slab (end of day, experimenting with an approach you might throw away), use `git stash` or a WIP branch — don't commit on `rustmigrate-z`. + +The step-order above is a **work-organization guide** — treat each step as a natural self-review savepoint where you run `cargo check --lib`, skim your own diff, and decide whether it's tight enough to move on to the next step. + +Work-order checkpoints: +- Step 2 — interner `<'s, 't>` flip + substrate lands (empty HashMaps, `alloc`/`alloc_slice_copy` wrappers, `Compiler::new` update). +- Step 3 — variable types + their `From`/`TryFrom` bridges. +- Step 4 — `IEnvEntryT` + `TemplatasStoreT` + `GlobalEnvironmentT`. +- Step 5 — 9 env variants + id-based `Hash`/`PartialEq` impls + builders + `IEnvironmentT` ↔ `IInDenizenEnvironmentT` bridges + `NodeEnvironmentBox` / `FunctionEnvironmentBoxT` / `IDenizenEnvironmentBoxT` deletion. +- Step 5.5 — 5 `&'s` → `&'t` env-ref flips in `templata.rs` / `types.rs`. +- Step 6 — interner bodies (the big one; split mentally by family if it helps stay organized). +- Step 7 — builder `build_in` implementations wired to interner. +- Step 8 — final `cargo check --lib` green, diff self-review, hand back to the human for review. + +## What "done" looks like + +- `cargo check --lib` passes with 0 errors. +- Every `*EnvironmentT` type in `env/environment.rs` and `env/function_environment_t.rs` has real Scala-parity fields (no `PhantomData`-only stubs). +- `IEnvironmentT<'s, 't>` has 9 `&'t _`-holding variants; `IInDenizenEnvironmentT<'s, 't>` has 6. +- `From`/`TryFrom` bridges: concrete ↔ `IEnvironmentT`, concrete ↔ `IInDenizenEnvironmentT`, `IInDenizenEnvironmentT` ↔ `IEnvironmentT`. +- `IEnvEntryT<'s, 't>` is a 5-variant inline enum. Old 5 struct stubs deleted; their Scala `/* */` blocks stay. +- `NodeEnvironmentBox`, `FunctionEnvironmentBoxT`, and `IDenizenEnvironmentBoxT` Rust stubs deleted. +- `IVariableT<'s, 't>` (4 variants), `ILocalVariableT<'s, 't>` (2 variants), and 4 concrete variable structs have real fields. +- `GlobalEnvironmentT<'s, 't>` exists as a real struct with `name_to_top_level_environment` and `builtins` fields. +- `TemplatasStoreT<'s, 't>` has slice-of-pairs layout per Gotcha 3. `TemplatasStoreBuilder<'s, 't>` exists with a `build_in` method. +- `NodeEnvironmentBuilder`, `FunctionEnvironmentBuilder`, etc. exist for each env kind that mutates during construction. Each has a `build_in` returning `&'t FooEnvironmentT`. +- `TypingInterner<'t>` has real bodies (`Bump` + per-family HashMaps + `RefCell`). All three Slab 2/3 intern methods (`intern_id`, `intern_prototype`, `intern_signature`) plus ~60 concrete-name + 6 Kind-payload + 6 templata-payload methods actually work. +- All Scala `/* */` blocks unchanged byte-for-byte. +- Tagged `slab-4-complete`. + +## When you're stuck + +- **"Cannot construct `IEnvironmentT` — it has private fields"**: the fields are `&'t _`, not private. Double-check you're using the right constructor (`IEnvironmentT::Function(&'t FunctionEnvironmentT)`, not `IEnvironmentT { function: … }`). +- **"`'t` does not outlive `'s`"**: you wrote `&'s FooEnvironmentT`. Change to `&'t FooEnvironmentT`. See Gotcha 1. +- **"HashMap lookup fails — query wrapper mismatch"**: the IDEPFL pattern has a `Query` wrapper type that wraps `&'tmp ValT<'s, 't, 'tmp>` and implements `Hash`/`Eq` compatibly with the stored `ValT<'s, 't, 't>`. Read `src/postparsing/names.rs`'s `RuneValQuery` for the live example. You need one per interned family that uses `'tmp`. +- **"Sub-compiler file X won't compile because NodeEnvironmentBox / FunctionEnvironmentBoxT doesn't exist"**: replace param types at those call sites. `&NodeEnvironmentBox<'s, 't>` → `&mut NodeEnvironmentBuilder<'s, 't>`; `&FunctionEnvironmentBoxT<'s, 't>` → `&mut FunctionEnvironmentBuilder<'s, 't>`. Body panics until Slab 8. If unsure, ask the senior; don't guess the right type. +- **"`OverloadSetT` stops compiling after I change `IInDenizenEnvironmentT`"**: two possible causes. (a) You lost the `Hash`/`Eq`/`PartialEq`/`Debug` derive on the wrapper enum itself — see Gotcha 10. (b) You haven't done the Step 5.5 `&'s` → `&'t` flip on `OverloadSetT.env`, so the field type still references the old scout-lifetime env — see Gotcha 11. The Slab-3 custom `ptr::eq`-based `PartialEq` impl on `OverloadSetT` stays the same; lifetime doesn't affect `ptr::eq`. +- **"I need `TypingBump` or `&'t Bump` and don't know where to get it"**: add a getter method on `TypingInterner`, or pass it as a separate constructor/build_in param. Scout_arena.rs does the former. +- **"Gotcha about a Scala method I need to port"** (`rootCompilingDenizenEnv`, `addEntry`, `makeChild`, etc.): don't. That's body work. Scala block stays in `/* */`; Rust body is `panic!()` until Slab 8. +- **"I want to modify `names.rs` / `types.rs` / `templata.rs` / `ast.rs`"**: don't. Slabs 2 and 3 are frozen. If you think a data definition there needs to change, the shape of Slab 4 probably shifted — ask the senior. + +## Where to file questions + +- **Design** (field layout, enum shape, arena lifetime): the reasoning doc + this handoff + `quest.md` Part 3 should cover it. If they don't, ask the senior. +- **Scala semantics**: the `/* */` block is the spec. If ambiguous, the senior has the Scala repo. +- **Interner implementation**: scout_arena.rs is the live reference. If you hit a wall on `'tmp` lifetime mechanics, read IDEPFL shield + scout_arena's `intern_rune` + the `@DSAUIMZ` reasoning doc on slice interning. +- **Hook rejections**: read the hook's diff output. Usually it's accidental whitespace change inside `/* */`. + +## Final advice + +This is the biggest slab so far. The data-definition parts (envs, variables, IEnvEntryT, GlobalEnvironmentT, TemplatasStoreT) follow the Slab 2/3 patterns you've already seen — mechanical once you know the rules. The fresh work is the interner implementation and the builder-freeze pattern. + +**Get the interner substrate (Step 2) working before you touch env structs.** If interner signatures change mid-slab, env `build_in` methods have to change too. One-way-door ordering: interner first, then data. + +**When a sub-compiler reference site breaks, default to `panic!("Unimplemented: Slab 8 signature rewrite")`.** Resist the urge to write correct bodies — that's not Slab 4's job. The goal here is shape, not behavior. + +**The reasoning doc (`environments-per-denizen-long-term.md`) captures why this slab is arena-based even though `Rc` would fit Scala better.** If you find yourself thinking "shouldn't this just be an `Rc`?" — yes, eventually, after Slab 8. Not now.

This is a ~2100-line file that already has every Scala `case class` / sealed trait embedded as a `/* */` block with a Rust stub struct/enum above it. Your job is to turn those stubs into real, Scala-parity data definitions — nothing more. No method bodies, no interner wiring (expressions are **not** interned), no visitor, no compiler logic. + +Compared to Slab 4, this slab is smaller and more mechanical — **no interner work, no builders, no From/TryFrom bridges across sibling enums, no heavy back-references to envs**. The tricky parts are all upfront: (a) the existing stubs are structurally unsound (see "Up-front: the stubs are infinitely-sized"), (b) three enums and ~44 payload structs have to be filled consistently, (c) AASSNCMCX applies — every `Vec` in a stub must become `&'t [T]`, and (d) every sub-expression field holds `&'t ReferenceExpressionTE<'s, 't>` / `&'t AddressExpressionTE<'s, 't>`, not by-value. Budget: plan for 0.5–1 workday if you stay focused. + +**Read these first in this order**, then come back: + +1. `quest.md` — at least **§§1.5, 6.4, 7 (all of Part 7), 12.1-Slab-5 paragraph**. Part 7 is the design spec; accurate, no known overrides. +2. `TL-HANDOFF.md` at repo root — the current top-level handoff. The "File layout + style standards for typing/" section is load-bearing for this slab; every new `impl` block in `expressions.rs` must follow it. +3. `.claude/rules/postparser/IDEPFL-postparser-interning.md` — the IDEPFL interning pattern. Skim only. **Expression AST is NOT interned** (§7.2), so you won't be adding `*ValT` companions or intern methods, but you should know what IDEPFL is so you understand why it doesn't apply here. +4. `FrontendRust/docs/migration/handoff-slab-4.md` — just §§"What 'done' looks like" and the first four Gotchas. Slab 4 settled the conventions around `#[derive]` on arena-allocated structs (ATDCX), `where 's: 't`, and the "wrapper enum is inline-Copy, payloads are `&'t`-refs" philosophy. Slab 5 reuses them verbatim — you're not re-deciding anything. +5. `FrontendRust/docs/shields/ArenaTypesDontClone-ATDCX.md` — the rule that expression AST payload structs don't derive `Clone`/`Copy`. One-page read. +6. `Luz/shields/ArenaAllocatedStructsShouldNotContainMallocdCollections-AASSNCMCX.md` (shield AASSNCMCX) — the rule that `Vec` / `HashMap` fields don't belong inside arena-allocated structs. The existing stubs all violate this; you'll fix them. +7. This doc. + +You shouldn't need to read the Scala source externally — every Scala `case class` / sealed trait is already embedded inline in the `/* ... */` blocks in `expressions.rs`. If a block is ambiguous, ask; don't guess. + +--- + +## The big picture: why Slab 5 exists + +After the typing pass resolves names, generic parameters, environments, and kinds, it produces a typed expression tree for each function body. That tree is what Slab 5 defines the shape of. In Scala: + +- `ExpressionT` is a `sealed trait` — the root of the tree. +- `ReferenceExpressionTE extends ExpressionT` — expressions whose result is a value/reference. ~38 concrete subclasses (`FunctionCallTE`, `IfTE`, `WhileTE`, `LetNormalTE`, etc.). +- `AddressExpressionTE extends ExpressionT` — expressions whose result is an address (an l-value). 5 concrete subclasses (`LocalLookupTE`, `ReferenceMemberLookupTE`, etc.). +- `IExpressionResultT` is a sealed trait for the *computed type* of an expression — `ReferenceResultT(coord)` or `AddressResultT(coord)`. Returned from `def result: IExpressionResultT` on every node. Not a tree node itself — just a 2-variant discriminated union over `CoordT`. + +In Rust, per `quest.md` Part 7: + +- **Three enums** (§7.1): `ReferenceExpressionTE<'s, 't>` (~38 variants), `AddressExpressionTE<'s, 't>` (5 variants), and a narrow wrapper `ExpressionTE<'s, 't>` (2 variants: `Reference(&'t ReferenceExpressionTE)` / `Address(&'t AddressExpressionTE)`). The first two are **inline-Copy wrappers** whose variants hold the payload struct inline by value; the third is a 2-variant `&'t`-ref wrapper used only in places where a slot can hold either. +- **~44 payload structs** — one per Scala `case class`. `#[derive(PartialEq, Eq, Hash, Debug)]`, **not** `Copy`/`Clone` (ATDCX — they're arena-allocated conceptually: the whole `ReferenceExpressionTE` enum lives in `'t`, so transitively the payload data lives there too). +- **Arena-allocated, not interned** (§7.2). Expression trees are unique per function body; no dedup. +- **Sub-expressions are `&'t` refs; collections are arena slices** (§7.2). A parent node's single child-expression field is `&'t ReferenceExpressionTE<'s, 't>` (or `&'t AddressExpressionTE<'s, 't>`); a parent's list-of-children field is `&'t [ReferenceExpressionTE<'s, 't>]` — a dense arena slice of inline-enum values, same pattern as `ConsecutorSE.exprs` in postparsing. +- **Can hold scout data** (§7.3). `RangeS<'s>`, `StrI<'s>`, etc. are fine as-is. +- **`IExpressionResultT` / `ReferenceResultT` / `AddressResultT`** — small inline `Copy` enum + two tiny wrapper structs. `ReferenceResultT { coord: CoordT }`, `AddressResultT { coord: CoordT }`, `IExpressionResultT::Reference(ReferenceResultT) | Address(AddressResultT)`. Not arena-allocated — too small (24 bytes), passed by value like `CoordT`. + +By the end of Slab 5: + +- `cargo check --lib` passes with 0 errors. +- `expressions.rs`: three real enums with all their variants, ~44 real payload structs with Scala-parity fields, `IExpressionResultT`/`ReferenceResultT`/`AddressResultT` are real 2-variant inline enum + 2 structs. +- Every `Vec` field in a payload struct has been flipped to `&'t [T]` per AASSNCMCX. +- Every by-value sub-expression field (`expr: ReferenceExpressionTE<'s, 't>`, `inner_expr: ReferenceExpressionTE<'s, 't>`, etc.) has been flipped to `&'t ReferenceExpressionTE<'s, 't>` / `&'t AddressExpressionTE<'s, 't>` per §7.2. **This is the most important structural change in this slab — see Gotcha 1.** +- All `fn equals` / `fn hash_code` / `fn result` / `fn new` stubs keep `panic!()` bodies. **Do not port the `vassert`/`vcurious`/`vfail` logic inside the Scala `/* */` blocks** — that's Slab 8+ body work. +- Scala `/* */` blocks unchanged byte-for-byte (the pre-commit hook enforces this). +- The file-layout conventions from TL-HANDOFF are preserved: `use` imports at top, class-then-impl ordering, one fn per impl block, multi-line impl bodies, `fn new(...)` panic-stub for any case class whose Scala body has `vassert`. + +**What Slab 5 is NOT:** + +- No interner wiring. Expression nodes aren't interned. +- No `*ValT` companions. Expression nodes aren't interned. +- No builders. Expression trees are constructed bottom-up by the expression compiler (Slab 8+), not via builder-freeze. +- No `From`/`TryFrom` bridges from payload to enum. Patterns are `ReferenceExpressionTE::FunctionCall(FunctionCallTE { … })` construction and `match` destructuring — no ceremony. (Contrast with Slab 2's names: there we wrote `From<&'t FunctionNameT> for INameT` because `INameT` wrapped `&'t FunctionNameT`. Here the wrapper enum holds the payload **by value**, so there's no indirection to bridge across — variants are constructed and matched directly.) +- No `NodeRefT` visitor, no `visit_*` functions, no `collect_*` macros. Quest.md §7.4 names them as "same as parsing/postparsing" (the existing examples live in `src/parsing/tests/traverse.rs` and `src/postparsing/test/traverse.rs`, ~1000+ lines each), but those were written in support of test suites. **The typing pass has no test suite yet** — Slab 9+ is test-driven and will write the visitor then. Slab 5 skips it entirely. (If you find yourself reaching for the visitor to make something compile, you've gone off-spec; ask the senior.) +- No method body migration. `def result`, `def equals`, `def lastReferenceExpr`, the extractor objects at the bottom of the file (`referenceExprResultStructName`, `referenceExprResultKind`), etc. all stay `panic!()`. + +--- + +## Up-front: the stubs are infinitely-sized + +**Read this section twice before writing any code.** It's the single biggest mental adjustment this slab requires. + +Open `src/typing/ast/expressions.rs`. You'll see ~44 payload struct stubs that look like this: + +```rust +pub struct LetAndLendTE<'s, 't> { + pub variable: ILocalVariableT<'s, 't>, + pub expr: ReferenceExpressionTE<'s, 't>, // ← by value + pub target_ownership: OwnershipT, +} + +pub struct DeferTE<'s, 't> { + pub inner_expr: ReferenceExpressionTE<'s, 't>, // ← by value + pub deferred_expr: ReferenceExpressionTE<'s, 't>, // ← by value +} + +pub struct ConsecutorTE<'s, 't> { + pub exprs: Vec>, // ← Vec + by value +} +``` + +These compile **today** only because the enum itself is `_Phantom`: + +```rust +pub enum ReferenceExpressionTE<'s, 't> { + _Phantom(std::marker::PhantomData<(&'s (), &'t ())>), +} +``` + +The enum has size 0 right now, so an inline `ReferenceExpressionTE` field is zero-cost. **The moment you fill the enum with its ~38 real variants — each carrying a payload struct that transitively may contain `ReferenceExpressionTE` again — the compiler rejects it with "recursive type has infinite size"**. The stubs were authored before the enum was filled, as placeholder shapes; they're wrong, and you're fixing them. + +**Two rules for the flip:** + +1. **Single sub-expression fields** (`expr`, `inner_expr`, `condition`, `array_expr`, `generator`, `source_expr`, etc.) → flip to `&'t ReferenceExpressionTE<'s, 't>` (or `&'t AddressExpressionTE<'s, 't>` depending on which wrapper Scala uses). +2. **`Vec` fields** (e.g. `ConsecutorTE.exprs`, `TupleTE.elements`, `FunctionCallTE.args`) → flip to `&'t [ReferenceExpressionTE<'s, 't>]`. This is a dense arena slice of inline-enum values; same pattern as `ConsecutorSE.exprs: &'s [IExpressionSE<'s>]` in postparsing. The elements stay inline (16 bytes each) — you're not also flipping them to `&'t ReferenceExpressionTE`. Rationale: postparsing already settled this; collections of small-inline-wrapper values are kept dense-packed, single-child slots are kept indirect. + +Same story for `AddressExpressionTE` sub-expressions (only `MutateTE.destination_expr` has one — it's `AddressExpressionTE`), and same story for the `Vec` fields (those become `&'t [ReferenceLocalVariableT<'s, 't>]` too — no `Vec` in arena-pinned structs per AASSNCMCX). + +After the flip, `LetAndLendTE` etc. become finite-sized: + +```rust +pub struct LetAndLendTE<'s, 't> { + pub variable: ILocalVariableT<'s, 't>, + pub expr: &'t ReferenceExpressionTE<'s, 't>, // 8 bytes + pub target_ownership: OwnershipT, // 1 byte +} + +pub struct DeferTE<'s, 't> { + pub inner_expr: &'t ReferenceExpressionTE<'s, 't>, // 8 bytes + pub deferred_expr: &'t ReferenceExpressionTE<'s, 't>, // 8 bytes +} + +pub struct ConsecutorTE<'s, 't> { + pub exprs: &'t [ReferenceExpressionTE<'s, 't>], // 16 bytes (ptr + len) +} +``` + +--- + +## Rules for each field translation + +Same rules as Slabs 2/3/4.

Flip sub-expr fields, flip `Vec<>` to `&'t []`, add `where 's: 't` if not present, replace `#[derive]` stanza with `#[derive(PartialEq, Eq, Hash, Debug)]` (or add it if missing — the current stubs have no `#[derive]` at all). + +### B. `impl` blocks with panic-stubbed methods (leave alone) + +```rust +impl<'s, 't> LetAndLendTE<'s, 't> { + fn result(&self) -> ReferenceResultT<'s, 't> { panic!("Unimplemented: result"); } +/* + override def result: ReferenceResultT = { … } +*/ +} +``` + +**Don't touch the `fn … { panic!(…) }` bodies.** Those are Slab 8+ method-migration work.

Body stays `panic!()`. This flip propagates to ~13 `fn new` stubs (`LetAndLendTE`, `DeferTE`, `ConsecutorTE`, `IsSameInstanceTE`, `RuntimeSizedArrayLookupTE`, `FunctionCallTE`, `ReinterpretTE`, `SoftLoadTE`, `DestroyStaticSizedArrayIntoFunctionTE`, `DestroyStaticSizedArrayIntoLocalsTE`, `DestroyImmRuntimeSizedArrayTE`, `FunctionDefinitionT`, `FunctionHeaderT` — the last two are in `ast/ast.rs`; you'll touch them only if their param types name a sub-expr type). + +**Don't add new `fn new` stubs unless the Scala case class has a `vassert` block you're newly exposing.** The existing set is complete. + +### D.

Slab 8 wires them into their actual impl blocks or deletes them. Don't touch. + +--- + +## Gotchas + +### Gotcha 1 (the big one): flip sub-expression fields from by-value to `&'t` + +Already covered in the "Up-front" section. Restating here as the single most important gotcha: + +- Single sub-expression → `&'t ReferenceExpressionTE<'s, 't>` / `&'t AddressExpressionTE<'s, 't>`. +- Collection of sub-expressions → `&'t [ReferenceExpressionTE<'s, 't>]` / `&'t [ExpressionTE<'s, 't>]`. +- Every `Vec` on a payload struct → `&'t [T]`. Covers both `Vec` and `Vec` (AASSNCMCX — no `Vec` in arena-pinned types). + +**Check after flip:** `grep -n "Vec<" src/typing/ast/expressions.rs` — should return zero hits in `pub struct FooTE` field positions. (It's fine if `Vec` shows up in a Scala `/* */` block, which is frozen, or in a `fn new` parameter list for a stub you haven't touched yet.) + +### Gotcha 2 (resolved): wrapper enum `Copy` — payloads aren't `Copy`, but the enum is, via `#[derive]` with inline-value variants + +`ReferenceExpressionTE::LetAndLend(LetAndLendTE)` holds the payload by value. But `LetAndLendTE` doesn't derive `Copy`/`Clone` (ATDCX). So can `ReferenceExpressionTE` derive `Copy, Clone`? + +**Answer: no.** If a variant's payload isn't `Copy`, the enum can't be `Copy` either — Rust requires all variants to be `Copy` for the enum to derive `Copy`. Same for `Clone`. + +So: + +```rust +#[derive(PartialEq, Eq, Hash, Debug)] // NOT Copy, NOT Clone +pub enum ReferenceExpressionTE<'s, 't> { /* … */ } + +#[derive(PartialEq, Eq, Hash, Debug)] // NOT Copy, NOT Clone +pub enum AddressExpressionTE<'s, 't> { /* … */ } +``` + +This is a real departure from Slab 2/3's "wrapper enums are Copy" philosophy — but it's forced by ATDCX applied to the payloads, and it's the right call. The expression tree is arena-allocated; callers hold `&'t ReferenceExpressionTE` (8 bytes) and don't need to Copy the enum value. + +**Consequence for `ExpressionTE`:** since it only holds `&'t ReferenceExpressionTE` and `&'t AddressExpressionTE` (8-byte refs), it CAN derive `Copy, Clone`: + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] // Copy OK — only holds refs +pub enum ExpressionTE<'s, 't> { + Reference(&'t ReferenceExpressionTE<'s, 't>), + Address(&'t AddressExpressionTE<'s, 't>), +} +``` + +Same for `IExpressionResultT` / `ReferenceResultT` / `AddressResultT` — those are tiny value types (just a `CoordT`), all `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]`. + +**If you're ever tempted to add `Copy, Clone` to `ReferenceExpressionTE` to fix a compile error:** don't. The error is almost certainly a downstream sub-compiler call site that was written against the old `_Phantom` enum (which was trivially `Copy`). Patch the call site with `panic!("Unimplemented: Slab 8 — reconstruct reference to ReferenceExpressionTE")` or `todo!()` instead; don't weaken the ATDCX invariant. + +### Gotcha 3: rename `ExpressionT` → `ExpressionTE` + +The current stub at line 116 is `pub enum ExpressionT<'s, 't>`. Per `quest.md` §7.1, the Rust name is `ExpressionTE`. Rename the Rust identifier; the Scala block (`/* trait ExpressionT … */`) stays frozen verbatim, because it's the Scala-side name. + +This rename propagates to exactly one call site in `expressions.rs` itself (`ConstructTE.args: Vec>` → `&'t [ExpressionTE<'s, 't>]`) plus the free-fn stubs `fn expression_result` / `fn expression_kind` that reference `ExpressionT` in their panic bodies (flip those too, they're part of the same slice-pipeline artifact). + +Downstream: `grep -rn "ExpressionT[^ETa-z]" src/typing/` for the dregs. `ExpressionT` is easy to mis-grep against `ExpressionTE` / `IExpressionResultT` / `ReferenceExpressionTE` — prefer the word-boundary form. If a sub-compiler file uses `ExpressionT` as a function param, flip to `ExpressionTE`. If compilation still breaks there, patch the body with `panic!("Unimplemented: Slab 8")`. + +### Gotcha 4: `ConstantIntTE.value: ITemplataT<'s, 't>` — phantom parameter erased per Slab 3 + +Scala: `value: ITemplataT[IntegerTemplataType]`. The outer `[IntegerTemplataType]` phantom was erased in Slab 3 (§6.6); `ITemplataT<'s, 't>` is monomorphic. Just use `ITemplataT<'s, 't>`. + +The existing stub has `value: ITemplataT<'s, 't>` plus a stray `_phantom: PhantomData<(&'s (), &'t ())>`. Drop the `_phantom` — `ITemplataT<'s, 't>` already anchors both lifetimes. + +### Gotcha 5: `ConstantStrTE.value: String` — use `StrI<'s>` instead + +Scala: `value: String`. The existing stub has `value: String` (owned, heap-allocated). + +Rust option landscape: +- **(a) `String`** — heap allocation inside an arena-pinned struct. AASSNCMCX violation. The destructor won't run on arena drop → leak. +- **(b) `StrI<'s>`** — already-interned scout string. Zero allocation at construction, pointer-identity lookup. +- **(c) `&'t str`** — arena-allocated slice, not interned. + +**Use (b): `value: StrI<'s>`.** Rationale: `ConstantStrTE` represents a source-literal string from the Vale program (e.g. `let x = "hello"`). Those string literals are tokenized and interned by the parser into the scout arena long before typing runs. The value coming into typing is always a `StrI<'s>` already. Re-interning to the typing arena or allocating owned `String` is wasteful and breaks AASSNCMCX. + +If you hit a call site (in a macro or sub-compiler) that constructs a `ConstantStrTE` from a Rust `&str` literal it made up itself, patch it with `panic!("Unimplemented: Slab 8 — intern string literal via scout arena")` until Slab 8 fixes it. + +### Gotcha 6: don't port `vassert` / `vcurious` / `vfail` bodies + +Every payload struct's Scala `/* */` block contains method bodies: + +``` +/* +case class LetAndLendTE(...) extends ReferenceExpressionTE { + vassert(variable.coord == expr.result.coord) + + (expr.result.coord.ownership, targetOwnership) match { + case (ShareT, ShareT) => + case (OwnT | BorrowT | WeakT, BorrowT) => + } + + expr match { + case BreakTE(_) | ReturnTE(_) => vwat() // See BRCOBS + case _ => + } + + override def result: ReferenceResultT = { … } +*/ +``` + +**All of this is Slab 8+ method work.** Slab 5 only fills the struct's fields. Every existing `fn new(...) { panic!(…) }` stub, every `fn result(...) { panic!(…) }` stub, every `fn equals(...) { panic!(…) }` stub stays with a `panic!()` body. + +You should be able to complete Slab 5 **without typing a `vassert` translation or a `match` pattern on any expression variant**. If you catch yourself doing either, you've drifted into Slab 8 work — back out. + +### Gotcha 7: `where 's: 't` — add to every payload struct, not just the wrapper enums + +Same as Slab 4 Gotcha 14. Any struct with `&'t FooBarT<'s, 't>` fields needs `where 's: 't` in the `impl` header and the struct header, otherwise the compiler errors with "`'s` may not live long enough". + +```rust +pub struct FunctionCallTE<'s, 't> +where 's: 't, +{ + pub callable: &'t PrototypeT<'s, 't>, + pub args: &'t [ReferenceExpressionTE<'s, 't>], + pub return_type: CoordT<'s, 't>, +} + +impl<'s, 't> FunctionCallTE<'s, 't> +where 's: 't, +{ + fn result(&self) -> ReferenceResultT<'s, 't> { panic!("Unimplemented: result"); } + /* … */ +} +``` + +The wrapper enums (`ReferenceExpressionTE`, `AddressExpressionTE`, `ExpressionTE`) compile without the bound because Rust infers it from their `&'t`-ref-holding variants (`ExpressionTE`) or from transitively-constrained payload types (the TE enums). Adding the bound uniformly doesn't hurt; your call. + +### Gotcha 8: pre-commit hook on `/* */` blocks (unchanged) + +`.claude/hooks/check-scala-comments` does exact-match on every Scala block. Rules from Slab 4 Gotcha 7: + +- Don't edit inside `/* */` blocks — frozen content. +- You may delete a Rust stub above a `/* */` block (hook only checks block content). You will NOT need to do this in Slab 5 — no type families collapse into enum variants the way `IEnvEntryT` did in Slab 4. +- You may reorder `/* */` blocks within a file if content stays identical. You will NOT need to do this either. + +The typical way to get bitten: you editor-auto-indents whitespace inside a `/* */` block and don't notice. The hook prints the diff when it rejects; read it, revert the block's content, re-stage. + +### Gotcha 9: file layout conventions from TL-HANDOFF — re-apply if you move things + +Summarized here for convenience (full spec in TL-HANDOFF.md §"File layout + style standards for typing/"): + +- `use` imports at file top. +- Scala `package …; import …` block sits below the `use` block, not above. +- Scala `case class` comment sits **above** its Rust `pub struct FooTE`. +- Per-method Scala `def foo` comment sits **inside** an `impl` block, **below** the Rust `fn foo`. +- **One fn per `impl` block** — each fn gets its own `impl<'s, 't> FooTE<'s, 't> { fn foo() { panic!(…); } /* scala */ }` wrapper. +- **Multi-line impl bodies** — don't collapse to one line even for trivial bodies. +- **No empty placeholder impls** — `impl<'s, 't> FooTE<'s, 't> {}` with zero methods gets deleted. +- **One `/* */` per Rust definition** — don't pack multiple definitions into one block. +- **`fn new(...)` scaffolding** — panic-bodied constructor stub for any case class with `vassert`. The existing file already has these for all the cases that need them; don't add or remove. + +The file already follows these conventions at the start of Slab 5. As you flip field types in struct stubs, the impl-block shape stays unchanged. If you find yourself *moving* an impl block or *changing* its shape, stop — you've drifted. The only edits are: (a) struct field types, (b) enum variant lists (`_Phantom` → real variants), (c) derive stanzas, (d) parameter types on `fn new` stubs to match the field flip. + +### Gotcha 10: downstream sub-compiler files will break — use `panic!("Unimplemented: Slab 8")` + +32 files under `src/typing/` reference `ReferenceExpressionTE` / `AddressExpressionTE` / `ExpressionT`. Most pass-through take `ReferenceExpressionTE<'s, 't>` by value as a param — fine, the wrapper enum is still small (its size is the max variant payload, ~80-ish bytes with the big payloads like `AsSubtypeTE`, but still passable by value). **Those call sites don't break.** + +What does break: +- Any site that constructs a struct like `LetAndLendTE { variable, expr, target_ownership }` using a by-value `ReferenceExpressionTE` for `expr`. After the flip to `&'t ReferenceExpressionTE`, that construction needs `&interner.alloc(expr)` or similar. **Patch the body with `panic!("Unimplemented: Slab 8 — allocate sub-expression into arena")`** — Slab 8 rewrites these when interner/compiler wiring happens. +- Any site that matches `ReferenceExpressionTE::_Phantom(_)` as a catch-all. After the flip, `_Phantom` is gone; the catch-all either needs to go (match is now exhaustive) or stays as `_ => …` — depends on the site. +- Any site that uses `ExpressionT` (the old name) — flip to `ExpressionTE`. + +Expected blast radius: ~10-30 sites across sub-compiler files. All should resolve to either trivial rename fixes or `panic!("Unimplemented: Slab 8")` patches. If a single site needs more than 10 lines of real logic to get compiling, you've drifted — back out and ask the senior. + +**Hot tip:** + +```bash +rg -n "ReferenceExpressionTE\b|AddressExpressionTE\b" src/typing/ --type rust | rg -v "/\*|\* " +``` + +gives you the active-code hits (filtering out `/* */` and `*` doc comments).

Every other collection of expressions (`ConsecutorTE.exprs`, `TupleTE.elements`, `StaticArrayFromValuesTE.elements`, `FunctionCallTE.args`, `InterfaceFunctionCallTE.args`, `ExternFunctionCallTE.args`) uses the narrow `&'t [ReferenceExpressionTE<'s, 't>]`. + +Rationale: closure structs can have **addressible members mixed with reference-valued ones**, so `ConstructTE.args` needs the wide wrapper. No other expression mixes reference and address at the list level. + +Rule of thumb when translating: what does the Scala field say? `Vector[ExpressionT]` → `&'t [ExpressionTE<'s, 't>]`; `Vector[ReferenceExpressionTE]` → `&'t [ReferenceExpressionTE<'s, 't>]`. Don't substitute one for the other. + +### Gotcha 12: the extractor-object free-fns at the bottom of the file stay panic-stubbed + +Lines 2068–2090 ish have: + +```rust +fn reference_expr_result_struct_name_unapply<'s, 't>(expr: &ReferenceExpressionTE<'s, 't>) -> Option> { panic!("Unimplemented: unapply"); } +/* +object referenceExprResultStructName { + def unapply(expr: ReferenceExpressionTE): Option[StrI] = { … } +} +*/ +``` + +These are Scala `object X { def unapply }` extractors — used in pattern matching like `case referenceExprResultStructName(name) =>`. They're a Slab 8+ concern. Leave as `panic!()`. Flip the param type from `&ReferenceExpressionTE` to `&ReferenceExpressionTE` (no change) — it's already a borrow; no flip needed. + +### Gotcha 13: no `From`/`TryFrom` bridges, no `*ValT` companions + +A clarification, since Slabs 2–4 all wrote From/TryFrom bridges: + +- **No From/TryFrom bridges.** Slab 2's bridges existed because name wrapper enums hold `&'t FooNameT` and constructors wanted an ergonomic `FooNameT → INameT` path. Here the wrapper enums hold payload **by value** (`ReferenceExpressionTE::If(IfTE { … })`), so you construct via plain variant syntax, no bridge needed. Same for destructuring via `match`. If a downstream caller reaches for a `From` impl, it was expecting the name-hierarchy convention — redirect them to the plain variant syntax. +- **No `*ValT` companions.** Expressions aren't interned (§7.2), so there's no IDEPFL hashmap to key on; no Val. + +If a previous slab's work has a pattern you half-remember, double-check whether it applies here before copy-pasting. Slab 5 is structurally the simplest of the 5 so far — when in doubt, do less, not more. + +--- + +## Step-by-step plan + +### Step 1: Confirm starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-5.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-5.txt +``` + +Must print `0`. If it doesn't, stop and ask the senior. Project sets `#![allow(unused_variables, unused_imports)]`, so don't rely on warning counts. + +### Step 2: Fill `IExpressionResultT` / `ReferenceResultT` / `AddressResultT` + +Small, self-contained, downstream-safe. Do this first. + +1. Replace `IExpressionResultT::_Phantom(...)` with `Reference(ReferenceResultT<'s, 't>) | Address(AddressResultT<'s, 't>)`. +2. `ReferenceResultT` and `AddressResultT` already have `{ pub coord: CoordT<'s, 't> }` — just add `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` to each if not present. +3. Add `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` to `IExpressionResultT`. +4. `cargo check --lib` → /tmp/sylvan-slab-5.txt, expect 0 errors. + +### Step 3: Fill the ~44 payload structs + +Go file-top-to-bottom. For each stub: + +1. Read the Scala `case class` in the `/* */` block. +2. Translate fields via the table at the top of this doc. Remember: + - Sub-expression fields → `&'t ReferenceExpressionTE<'s, 't>` or `&'t AddressExpressionTE<'s, 't>`. + - Collection fields → `&'t [...]`. + - `StructTT` / `InterfaceTT` / `PrototypeT` / array `TT` types → `&'t` refs (interned). + - `CoordT` / `IdT` / `IVarNameT` / `ILocalVariableT` / `ISuperKindTT` / `ITemplataT` / `OwnershipT` / `VariabilityT` / `RegionT` → inline by value. + - `String` → `StrI<'s>` (Gotcha 5). +3. Drop `_phantom` fields that are no longer needed (e.g. `ConstantIntTE` once `value: ITemplataT<'s, 't>` anchors both lifetimes). Keep `_phantom` for truly fieldless structs (`VoidLiteralTE { region: RegionT, _phantom }`, `BreakTE { region, _phantom }`, `ConstantBoolTE { value: bool, region, _phantom }`, `ConstantFloatTE { value: f64, region, _phantom }`). +4. Add `#[derive(PartialEq, Eq, Hash, Debug)]` to the struct — NOT `Copy`/`Clone`. +5. Add `where 's: 't` to struct header if any field is `&'t _`. +6. If the stub has a `fn new(...)` stub with a sub-expr param, flip the param type to match the field flip. Body stays `panic!()`. + +After every ~10 structs, `cargo check --lib` to catch cascading errors early. You may see errors in the existing `fn result` / `fn equals` / `fn new` panic stubs complaining about the field-type mismatch — fix only the parameter types (to match the new field types), not the bodies. + +### Step 4: Fill the three wrapper enums + +1. Replace `ReferenceExpressionTE::_Phantom` with the ~42 real variants (one per Scala subclass of `ReferenceExpressionTE`). Derive `PartialEq, Eq, Hash, Debug` — NOT `Copy`, NOT `Clone` (Gotcha 2). +2. Replace `AddressExpressionTE::_Phantom` with 5 real variants. Same derive. +3. Rename `ExpressionT` → `ExpressionTE` (Gotcha 3) and fill with 2 variants: `Reference(&'t ReferenceExpressionTE<'s, 't>)` / `Address(&'t AddressExpressionTE<'s, 't>)`. Derive `Copy, Clone, PartialEq, Eq, Hash, Debug`. +4. `cargo check --lib` → /tmp/sylvan-slab-5.txt. + +You'll hit downstream errors here — mostly in sub-compiler files that used the old `_Phantom`-erased signature or by-value `ReferenceExpressionTE` fields. Fix per Gotcha 10: rename `ExpressionT` → `ExpressionTE` where it appears, patch struct-construction sites with `panic!("Unimplemented: Slab 8 — arena-allocate sub-expression")` if they need a ref-conversion. + +### Step 5: Sweep downstream errors + +Now the bulk of compile errors. Handle them in this order: + +1. `ExpressionT` → `ExpressionTE` renames across sub-compiler files. Mechanical. +2. By-value construction sites (e.g. `LetAndLendTE { expr: some_ref_expr, … }` when `expr` is now `&'t`). Patch body with `panic!("Unimplemented: Slab 8")`. +3. Pattern-match sites that destructured `_Phantom`. Those either get real pattern arms (if the body is obvious and mechanical — rare) or `_ => panic!("Unimplemented: Slab 8 — match over ReferenceExpressionTE variants")`. + +Heuristic: **if a body is more than 5 lines of fix, panic it out instead**. Slab 5 is data-definition; bodies are Slab 8+. + +### Step 6: Verify and hand off + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-5.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-5.txt # must be 0 +grep -n "_Phantom\b" FrontendRust/src/typing/ast/expressions.rs +# ^ should show 0 hits +grep -n "^\s*pub .*: ReferenceExpressionTE<" FrontendRust/src/typing/ast/expressions.rs +# ^ should show 0 hits (every field is &'t ReferenceExpressionTE<… or &'t [ReferenceExpressionTE<…) +grep -n "^\s*pub .*: Vec<" FrontendRust/src/typing/ast/expressions.rs +# ^ should show 0 hits +grep -n "^\s*pub enum ExpressionT\b" FrontendRust/src/typing/ast/expressions.rs +# ^ should show 0 hits (renamed to ExpressionTE) +``` + +**Never commit.

Same drill for `AddressExpressionTE`. +- **"the trait bound `FooTE<'_, '_>: Copy` is not satisfied"**: you tried to derive `Copy` on `ReferenceExpressionTE` or `AddressExpressionTE`. See Gotcha 2. Remove `Copy` and `Clone` from the derive on those two enums. `ExpressionTE` keeps Copy because it only holds refs. +- **"`ReferenceExpressionTE` cannot be constructed outside of the crate"**: you forgot `pub` on a variant or on the enum itself. Slab 5 preserves all `pub` qualifiers from the stubs. +- **"mismatched types: expected `&'t ReferenceExpressionTE`, found `ReferenceExpressionTE`"** at a sub-compiler call site: that's Gotcha 10 — patch the site with `panic!("Unimplemented: Slab 8 — allocate into arena")` or the fixup `interner.alloc(expr)` if the context is trivially arena-aware.

That method isn't Slab 5 work — it's Slab 8's `impl ReferenceExpressionTE { fn result(&self) -> ReferenceResultT { match self { … } } }`. Patch the call site with `panic!("Unimplemented: Slab 8 — dispatch .result() across expression variants")`. +- **Pre-commit hook rejection on a `/* */` block**: you accidentally edited whitespace inside a frozen Scala block. Read the hook's diff output and revert the block's content byte-for-byte. The hook only checks block content, not surrounding code. +- **"I want to port a `vassert` body because it would make my code feel complete"**: don't. Slab 8+ work. Scala body stays in `/* */`, Rust `fn new { panic!(…) }`. If you can't resist, put your would-be port in a side note and hand it back with the slab for the senior to accept or reject — don't bake it into the diff. +- **"I want to add a new type or helper not in the stubs"**: don't. If a downstream file is missing something, patch its call site to panic. Adding to `expressions.rs` outside the existing stub set is Slab 8+ work (or Slab 9+ for visitors). +- **"I want to touch `names.rs` / `types.rs` / `templata.rs` / `env/*.rs` / `ast/ast.rs`"**: don't. Slabs 2/3/4 are frozen. If you think one of those files needs a change to support Slab 5, the shape of Slab 5 probably shifted — ask the senior. The one narrow exception is `ast/ast.rs` `fn new` parameter types (`FunctionDefinitionT::new`, `FunctionHeaderT::new`) if they reference the flipped sub-expr types; flip those params to match, keep bodies `panic!()`. + +## Where to file questions + +- **Design**: `quest.md` Part 7 is the spec; this doc is the detailed how.

If the Scala `/* */` block is ambiguous, the senior has the Scala repo. +- **Field-type disagreements** (inline vs `&'t`): check the rules table at the top, then Gotcha 1. When in doubt between "inline Copy wrapper" and "`&'t` interned ref", the rule is: **interned Slab 3 payloads (StructTT, InterfaceTT, PrototypeT, array TT types) are always `&'t`; everything else is inline**. +- **Scala semantics** (`vassert`, `BRCOBS`, `RMLRMO`, `DDSOT`, etc.): these are acronym-codes for design rationale. They're documented elsewhere in the Scala repo but irrelevant for Slab 5 — you're not porting the assertions. Ignore. +- **Hook rejections**: read the hook's diff output. Usually accidental whitespace inside `/* */`. + +## Final advice + +Slab 5 is the mechanical payoff slab. Slabs 2–4 each had a design question that took senior input (Slab 2: DAG of sub-enums, Slab 3: KindT inline-vs-interned, Slab 4: envs-in-`'t` + one-map-per-family). Slab 5 has **no outstanding design question** — Part 7 is accurate, the philosophy is settled by Slab 4 (arena-allocated payload structs, `#[derive(PartialEq, Eq, Hash, Debug)]` no Copy/Clone, `&'t`-refs for interned/sub-expr slots, `&'t [...]` for collections). + +What's left is: read the Scala, translate the fields, flip the three sub-expr patterns (`expr: ReferenceExpressionTE` → `&'t ReferenceExpressionTE`, `Vec<...>` → `&'t [...]`, `String` → `StrI<'s>`), fill the three wrapper enums, sweep downstream `panic!("Unimplemented: Slab 8")` patches.

Slab 4 fixed the conventions this slab inherits (`where 's: 't` on every `'t`-holding struct, wrapper enums vs concrete derives, the `'t`-vs-`'s` env lifetime, idiomatic `Copy`-out-then-mutate). +4. `Luz/shields/ArenaAllocatedStructsShouldNotContainMallocdCollections-AASSNCMCX.md` — the shield. **`CompilerOutputs` is NOT arena-allocated** (stack-owned accumulator), so the shield doesn't apply to it; `HashMap`/`HashSet`/`Vec`/`VecDeque` are fine here. This is a genuine exception to the shield, and it's worth reading the shield first so you understand *why* the exception holds (the stack-owned accumulator's drop runs destructors; the arena's doesn't). +5. This doc. + +You shouldn't need to read the Scala source externally — every Scala `case class` / sealed trait / `val`-field is already embedded inline in the `/* ... */` blocks in `compiler_outputs.rs`. If a block is ambiguous, ask; don't guess. + +--- + +## The big picture: why Slab 6 exists + +Every typing-pass sub-compiler (function compiler, struct compiler, overload resolver, ...) needs to write into a shared accumulator: "I've declared a type called `MyStruct`", "here's the signature of a function I just resolved", "this impl connects this struct to that interface", "defer evaluating this body until later". Scala does this with a mutable case class (`CompilerOutputs()`) full of `mutable.HashMap` / `mutable.ArrayBuffer` / `mutable.LinkedHashMap` fields. Rust does the same shape with `std::collections::HashMap` + `Vec` + `VecDeque`, keyed via a pointer-identity newtype. + +The key engineering concern: **how do you hash a `&'t InternedT` for HashMap lookup?** Options: + +- Derive `Hash` on the inner type → walks every field; slow and diverges from Scala's reference-equality. +- `std::ptr::hash(&self.0, state)` → fast, pointer-identity, matches Scala's `eq` after interning. + +`quest.md` §4.2 picks option 2 via a `PtrKey<'t, T>(&'t T)` newtype. The wrapper's `Hash`/`Eq` use pointer identity; callers wrap an interned `&'t SomethingT` in `PtrKey(ref)` when inserting/looking up. This gives O(1) hash and `ptr::eq` lookup — exactly the Scala parity you'd expect from a post-interning HashMap. + +The second concern: **deferred actions**. Scala has `mutable.LinkedHashMap[Key, DeferredEvaluatingFoo]` where `DeferredEvaluatingFoo.call: (CompilerOutputs) => Unit` — a closure that captures `coutputs`. In Rust, `Box` would work but hides captures and costs a heap alloc per deferral. §4.4 replaces it with a tagged enum carrying the action parameters; the drain loop matches on the variant and calls the corresponding `Compiler::do_X` method with `&mut coutputs`. No `Box`, no `dyn`, no hidden captures, no self-borrow. + +By the end of Slab 6: + +- `cargo check --lib` passes with 0 errors. +- `src/typing/compiler_outputs.rs`: + - `PtrKey<'t, T>` newtype with pointer-identity `Hash`/`PartialEq`/`Eq` + `Copy`/`Clone`. + - `CompilerOutputs<'s, 't>` struct with ~20 real fields per §4.1 (with the `'t`-env override from Slab 4 applied). + - `DeferredActionT<'s, 't>` enum with 2 variants (per §4.4); the existing `DeferredEvaluatingFunctionBody` and `DeferredEvaluatingFunction` struct stubs are deleted (they roll into enum variants; Scala `/* */` blocks stay as audit trail, no Rust sibling). + - `CompilerOutputs::new()` constructor that initializes every field to empty. +- ~50 existing free-fn method stubs on `CompilerOutputs` stay `panic!()`. Don't port bodies. +- Scala `/* */` blocks unchanged byte-for-byte. +- File layout per TL-HANDOFF conventions preserved. + +**What Slab 6 is NOT:** + +- No method body migration (`declare_function_return_type`, `add_function`, `get_instantiation_bounds`, etc. stay panic-stubbed). +- No `Compiler::new` / `run_typing_pass` wiring — that's Slab 7. +- No `HinputsT` changes — Slab 7. +- No sub-compiler file fixes — Slab 8.

Rationale: (a) keeps `compiler_outputs.rs` focused on the accumulator; (b) Slab 7/8 consumers (Compiler methods, HinputsT construction) will need `PtrKey` too, and a separate module is cleaner than a deep import path; (c) mirrors how `TypingInterner` lives in its own file. + +If `mod.rs` doesn't currently declare submodules in a pub way, just add `mod ptr_key;` and use the full path `crate::typing::ptr_key::PtrKey`. Don't rearrange the rest of `mod.rs`. + +**Why `T: ?Sized`?** Forward-compat — allows `PtrKey<'t, dyn SomeTrait>` or slices in the future.

Keep the bound as written — it's harmless and matches the spec. + +**Why manual `Copy`/`Clone` instead of `#[derive]`?** `#[derive(Copy, Clone)]` would require `T: Copy + Clone`. The wrapped reference `&'t T` is `Copy` regardless of `T`, but the derive macro doesn't know that. Writing the impls by hand lets `PtrKey<'t, T>` be `Copy` for any `T: ?Sized` — including non-`Copy` types like `FunctionDefinitionT` (which can't be `Copy` per ATDCX, but their `&'t` refs are). + +--- + +## The `CompilerOutputs<'s, 't>` structure + +Per quest.md §4.1 with the Slab-4 env-lifetime override applied (Gotcha 1).

The Scala side has this as `case class CompilerOutputs()` with mutable collections initialized inline; your `new()` is the Rust equivalent. No Scala `/* */` equivalent needed for `new()` — Scala's default constructor isn't a separate definition to anchor. Just the `impl` block with the fn inside. + +--- + +## The `DeferredActionT<'s, 't>` enum + +Per quest.md §4.4, with the Slab-4 `'t`-env override applied: + +```rust +pub enum DeferredActionT<'s, 't> +where 's: 't, +{ + EvaluateFunctionBody { + prototype: &'t PrototypeT<'s, 't>, + function_env: &'t FunctionEnvironmentT<'s, 't>, // '&t, not '&s — see Gotcha 1 + origin: &'s FunctionA<'s>, + }, + EvaluateFunction { + name: &'t IdT<'s, 't>, + calling_env: &'t IInDenizenEnvironmentT<'s, 't>, // '&t; IInDenizenEnvironmentT for env scope + origin: &'s FunctionA<'s>, + template_args: &'t [ITemplataT<'s, 't>], + }, +} +``` + +**Why two variants and not more?** The Scala side has two existing `case class`es — `DeferredEvaluatingFunctionBody` and `DeferredEvaluatingFunction` — that already cover the cases. If body-migration later discovers a third kind of deferred action, quest.md §4.4's "Add variants as needed" clause applies. For Slab 6, match the Scala source: two variants. + +**Why no `Box`?** Scala's `call: (CompilerOutputs) => Unit` closure captures whatever context it needs. Rust closures capture environment too, but (a) they force a heap alloc per deferral, (b) they hide the capture list from audit review, and (c) `Box` has lifetime trouble with `&mut self` in the drain loop. The structured-enum approach makes captures explicit fields, costs nothing to pop (`VecDeque::pop_front` moves the value out), and the drain loop just matches and calls the right `Compiler` method. See quest.md §4.4's invariant: "`DeferredActionT` variants hold only owned or `Copy` context; they never reference `CompilerOutputs` itself." + +**Derive.** No `#[derive]` — see "Derives" above. Manually implementing `Debug` would require all variant payloads to be `Debug`; `FunctionA` isn't, so skip it. If any downstream caller wants to debug-print a `DeferredActionT`, they can match on the variant and print fields individually. + +**Naming.** Scala's `DeferredEvaluatingFunctionBody` / `DeferredEvaluatingFunction` become `DeferredActionT::EvaluateFunctionBody` / `DeferredActionT::EvaluateFunction` — quest.md §4.4's naming. The Rust side is more "action" than "evaluating", but the spec says `DeferredActionT`, so use it. The Scala `/* */` blocks for both deleted structs stay in the file (pre-commit hook requires it); just place them next to their corresponding enum variants as audit-trail anchors (see Gotcha 5 for block placement after stub deletion). + +--- + +## Gotchas + +### Gotcha 1 (critical): envs are `&'t IInDenizenEnvironmentT`, not `&'s IEnvironmentT` + +`quest.md` §4.1 shows env map values as `&'s IEnvironmentT<'s, 't>`. Both parts of that are wrong for the current codebase: + +- **`&'s` → `&'t`.** Slab 4 moved envs into the typing arena (`'t`), not the scout arena (`'s`). A `'s`-allocated env can't hold the `&'t` refs that `TemplatasStoreT` transitively requires. This is documented in the TL-HANDOFF "overrides" section and in `docs/reasoning/environments-per-denizen-long-term.md`. Apply uniformly: every env-map value in `CompilerOutputs` becomes `&'t`, not `&'s`. +- **`IEnvironmentT` → `IInDenizenEnvironmentT`.** Check the Scala blocks in `compiler_outputs.rs` (lines 75, 78, 86, 93): they say `mutable.HashMap[IdT[IFunctionTemplateNameT], IInDenizenEnvironmentT]` — specifically the narrower 6-variant in-denizen enum (Slab 4), not the wider 9-variant `IEnvironmentT`. §4.1 is off by that narrowing. Use `IInDenizenEnvironmentT` for all four env maps (`function_name_to_outer_env`, `function_name_to_inner_env`, `type_name_to_outer_env`, `type_name_to_inner_env`) and for the `calling_env` field on `DeferredActionT::EvaluateFunction`. + +**`FunctionEnvironmentT` in `DeferredActionT::EvaluateFunctionBody`** is different — it's specifically a `FunctionEnvironmentT`, one of the concrete env types (not the wrapper enum). Use `&'t FunctionEnvironmentT<'s, 't>`. That matches Scala exactly. + +### Gotcha 2: `CompilerOutputs` is stack-owned, so `HashMap`/`Vec`/`VecDeque` are fine (AASSNCMCX does NOT apply) + +AASSNCMCX (`ArenaAllocatedStructsShouldNotContainMallocdCollections`) bans `HashMap`/`Vec` inside arena-allocated structs because the arena's drop doesn't run destructors → leak. `CompilerOutputs` is NOT arena-allocated — it's stack-owned, constructed in `run_typing_pass` via `let mut coutputs = CompilerOutputs::new()`, dropped at pass end by normal Rust RAII. The HashMaps, HashSets, Vec, and VecDeque inside it all get their destructors run. No leak. + +So: freely use `std::collections::HashMap`, `std::collections::HashSet`, `std::collections::VecDeque`, and `Vec`. Not `hashbrown::HashMap` — the interner uses hashbrown for heterogeneous `'tmp`→`'t` lookup, but `CompilerOutputs` keys are homogeneous `PtrKey<'t, T>` on both insert and lookup, so `std::HashMap` is fine. + +### Gotcha 3: `Vec<&'t ImplT>` in HashMap values is an AASSNCMCX non-issue too — same rationale as Gotcha 2 + +Two fields need `HashMap>`: +- `sub_citizen_template_to_impls` — reverse index: "given this citizen template, list all impls that target it as sub-citizen" +- `super_interface_template_to_impls` — reverse index: "given this interface template, list all impls that target it as super-interface" + +The `Vec` is mutable (new impls get pushed as they're discovered), so `&'t [...]` is wrong — you can't push to an arena slice. Keep `Vec<&'t ImplT<'s, 't>>` for both. Same rationale as Gotcha 2: `CompilerOutputs` is stack-owned, so its internal `Vec`s get dropped properly. + +Quest.md §4.3 calls out that these two fields are **exceptions to the copy-out invariant** (most HashMap values are `Copy` and can be copied-out-before-mutate; these can't because `Vec` isn't `Copy`). Access them via `mem::take(&mut map.entry(key).or_default())` / `drain()` / reinsert patterns when Slab 8 migrates bodies. Nothing for you to do at data-definition time — just make sure the field type is `Vec<&'t ImplT<'s, 't>>`, not `&'t [ImplT]` or similar. + +### Gotcha 4: Deferred queues — `VecDeque`, not `LinkedHashMap` + +Scala uses `mutable.LinkedHashMap[PrototypeT, DeferredEvaluatingFunctionBody]` — insertion-ordered map keyed on the prototype. The typical access pattern is `headOption` (FIFO peek) + removal by key. Rust's `VecDeque` gives FIFO-peek via `front()` and FIFO-pop via `pop_front()`; it's the natural replacement. + +**Key difference:** Scala's `LinkedHashMap` supports keyed removal (`-= prototype`). `VecDeque` doesn't — removal is FIFO-only via `pop_front`. That matches the Scala drain pattern (`peekNext…Compile` + `markDeferredFunction…Compiled` always operate on the head), so it's fine. If Slab 7/8 discovers a case where mid-queue removal is required, switch to `indexmap::IndexMap` — but `VecDeque` is what §4.4 prescribes. Don't pre-optimize. + +Two companion sets track what's been completed — `finished_deferred_function_body_compiles: HashSet>` and `finished_deferred_function_compiles: HashSet>`. Scala uses `LinkedHashSet` for these (insertion-ordered); Rust's `HashSet` drops ordering but keeps O(1) membership, which is what `vassert(finishedSet contains prototype)` assertions actually need. Ordering loss is fine. + +### Gotcha 5: Delete the `DeferredEvaluatingFunctionBody` / `DeferredEvaluatingFunction` struct stubs; their Scala blocks stay + +The existing stubs at lines 37 and 46 are: +```rust +pub struct DeferredEvaluatingFunctionBody<'s, 't> { + prototype_t: PrototypeT<'s, 't>, + call: fn(), +} +/* +case class DeferredEvaluatingFunctionBody(...) +*/ +``` + +The `call: fn()` field is a Rust-side placeholder that doesn't match Scala's `call: (CompilerOutputs) => Unit`; it's a mid-slice-pipeline artifact. Both structs get rolled into `DeferredActionT` variants, so the Rust `pub struct …` definitions are **deleted**. The Scala `/* */` blocks stay in the file byte-for-byte (pre-commit hook rule). Place the two enum variants (`EvaluateFunctionBody`, `EvaluateFunction`) so they're anchored near their Scala blocks — variant-by-variant like Slab 4's `IEnvEntryT`. + +Suggested placement: +1. Write `pub enum DeferredActionT<'s, 't> { … two variants … }` above the `/* case class DeferredEvaluatingFunctionBody */` block, so the enum declaration comes first and both Scala blocks sit below as audit trail. +2. Delete the `pub struct DeferredEvaluatingFunctionBody` and `pub struct DeferredEvaluatingFunction` stub lines. Leave the `/* */` blocks in place, unchanged. + +Alternative: split the enum into two `impl` placeholders with per-variant anchoring (overkill — it's two variants, one enum is cleaner). + +### Gotcha 6: `HashSet>` wraps the key, not the inner ref + +When inserting a name into `type_declared_names: HashSet>>`, the caller does `set.insert(PtrKey(id_ref))`, not `set.insert(id_ref)`. Same for lookup: `set.contains(&PtrKey(id_ref))`. Slab 8+ bodies will do this; you just need to get the type right. + +`PtrKey` is `Copy`, so passing it around is cheap. Don't take `&PtrKey` where `PtrKey` by value works — `Copy` makes it free. + +### Gotcha 7: `std::HashMap` default hasher is fine; don't bring in `hashbrown` or a custom `BuildHasher` + +The `TypingInterner` uses `hashbrown::HashMap` because it needs heterogeneous lookup via `hashbrown::Equivalent` (to match a `'tmp`-borrowed query Val against a `'t`-owned stored Val). `CompilerOutputs` has no heterogeneous-lookup concern — both the insert and the lookup use `PtrKey<'t, T>` with the same `'t`. `std::collections::HashMap` with the default `RandomState` hasher is correct and cheap enough (pointer hashes are basically free). + +If a Slab 7/8 downstream profiles the compiler and finds hashing is a bottleneck, consider `ahash` or `fxhash` as a drop-in `BuildHasher`. Not a Slab 6 concern. + +### Gotcha 8: `CompilerOutputs` is NOT `Default` / `Clone` / `Copy` + +Don't derive any traits on `CompilerOutputs` itself. It's a mutable accumulator with nontrivial constructor semantics. The sub-compilers take `&mut CompilerOutputs<'s, 't>` and mutate it directly. Cloning would duplicate all the HashMap state — wrong semantically. + +If someone later wants `CompilerOutputs::default()`, they can write `fn default() -> Self { Self::new() }` as a `Default` impl — but don't add it speculatively. Slab 7's top-level wiring will use `CompilerOutputs::new()` explicitly. + +### Gotcha 9: Pre-commit hook on `/* */` blocks (unchanged) + +Same rule as every prior slab. `.claude/hooks/check-scala-comments` does exact-match comparison on every `/* ... */` Scala block. Rules for this slab: + +- Don't edit inside `/* */` blocks — frozen content. +- You can delete the two `pub struct DeferredEvaluating*` Rust stubs above their Scala blocks as long as the `/* */` content stays byte-for-byte (see Gotcha 5). +- You can replace the `pub struct CompilerOutputs(...)` PhantomData stub with a real struct, as long as the `/* case class CompilerOutputs() { … }` block that follows stays identical. +- You cannot reformat the whitespace inside any Scala block, even by accident. Editor auto-indenting inside a frozen block will bounce at commit time. If the hook rejects your commit, read its diff — it'll show exactly which block diverged. + +### Gotcha 10: No method body migration (read this before you're tempted) + +The file has ~50 free-fn method stubs like `fn declare_function_return_type(...)`, `fn add_function(...)`, `fn get_instantiation_bounds(...)`, `fn mark_deferred_function_body_compiled(...)`. Every one of them has a `panic!("Unimplemented: …")` body and a `/* def foo … */` Scala block below it, often containing complex logic (`vassert` chains, pattern matches on deeply nested `IdT` structures, etc.). + +**Leave every one of these alone.** They are Slab 8 work. + +A few of them will look tempting because the body is trivial (`peekNextDeferredFunctionBodyCompile` is just `deferredFunctionBodyCompiles.headOption.map(_._2)`). **Still don't port.** Consistency wins — if you port one, the next slab-6 reader might assume they all stay as-is and you've just introduced a trap. If a stub's panic body keeps downstream from compiling, patch the downstream call site with `panic!("Unimplemented: Slab 8 — CompilerOutputs::foo")` instead. Method bodies are Slab 8. + +### Gotcha 11: Idempotent writes (§4.5) aren't your concern here + +Quest.md §4.5 mentions that during overload resolution, `attempt_candidate_banner` writes to `coutputs` even for candidates that may be rejected, and safety rests on the writes being idempotent. That's a *runtime* invariant on how sub-compilers use `CompilerOutputs` — not a field-shape or derive concern. Slab 6 doesn't enforce it at the type level. Skip. + +### Gotcha 12: `InstantiationBoundArgumentsT` is incomplete — reference it but don't fix it + +Look at `src/typing/hinputs_t.rs:60`. `InstantiationBoundArgumentsT<'s, 't>` exists but has `Vec<(IRuneS<'s>, ())>` placeholders where Scala has `HashMap[IRuneS, PrototypeT[...]]`. The `()` is a stand-in for a type that depends on Slab 7/8 plumbing not yet done. + +For Slab 6's purposes, use `&'t InstantiationBoundArgumentsT<'s, 't>` as the value type in `instantiation_name_to_bounds`. You're just storing refs to the (partially-stubbed) type; you're not reaching into its fields. If you're ever tempted to fix the stub, don't — it's Slab 7/8. + +--- + +## Step-by-step plan + +### Step 1: Confirm starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-6.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-6.txt +``` + +Must print `0`. If not, stop and ask the senior. Project sets `#![allow(unused_variables, unused_imports)]`, so warnings are expected noise — only errors matter. + +### Step 2: Add `PtrKey<'t, T>` in its own module + +1. Create `src/typing/ptr_key.rs` with the `PtrKey` definition + impls from "The `PtrKey<'t, T>` shape" section above. ~35 lines. +2.

Expect 0 errors. + +### Step 3: Define `DeferredActionT<'s, 't>` and delete the two existing stub structs + +1. In `src/typing/compiler_outputs.rs`, replace the `pub struct DeferredEvaluatingFunctionBody … / pub struct DeferredEvaluatingFunction …` stubs with a single `pub enum DeferredActionT<'s, 't> where 's: 't { EvaluateFunctionBody { … }, EvaluateFunction { … } }`. Place the enum above the first deleted stub's Scala block. +2. Keep both `/* case class … */` blocks in place, byte-for-byte. +3. `cargo check --lib`. Any sub-compiler file that references `DeferredEvaluatingFunctionBody` / `DeferredEvaluatingFunction` by name will break; patch those references with `panic!("Unimplemented: Slab 8 — DeferredActionT")` or similar. (Expected blast radius: 0-3 sites.) + +### Step 4: Replace `CompilerOutputs` stub with the real struct + +1. Replace `pub struct CompilerOutputs<'s, 't>(pub std::marker::PhantomData<…>);` with the full field list from "The `CompilerOutputs<'s, 't>` structure" section above. ~23 fields. +2. Add `use` imports at the top for `std::collections::{HashMap, HashSet, VecDeque}` if not already present, and `use crate::typing::ptr_key::PtrKey;` (or the appropriate path). +3. Respect the `where 's: 't` bound on the struct header. +4. Don't add any `#[derive]` — `CompilerOutputs` derives nothing. +5. `cargo check --lib`. Downstream breakage is expected here; most fixes are either `panic!("Unimplemented: Slab 8")` patches or mechanical type-param fixes (e.g. a sub-compiler method sig that says `coutputs: &mut CompilerOutputs<'_, '_>` may need `<'s, 't>` elision fixed). + +### Step 5: Add `CompilerOutputs::new()` constructor + +1. Add a single-fn `impl<'s, 't> CompilerOutputs<'s, 't> where 's: 't { fn new() -> Self { … } }` block initializing every field to empty (see "Constructor" subsection). Follow TL-HANDOFF file-layout conventions (one fn per impl, multi-line body). +2. `cargo check --lib`. Clean. + +### Step 6: Sweep downstream errors + +Expected errors here: +- Sub-compiler files that construct `CompilerOutputs` directly or call methods that now have new field-type requirements.

No derives on `DeferredActionT` or `CompilerOutputs`. +- **"mismatched types: expected `&'t IInDenizenEnvironmentT`, found `&'s IEnvironmentT`"** at a sub-compiler call site: the Slab-4 `'t`-env override means the env ref you're passing is the wrong lifetime or the wrong wrapper. Patch the call site with `panic!("Unimplemented: Slab 8")` unless it's a trivial rename. Don't try to thread the lifetime fix through a sub-compiler body — that's Slab 8. +- **"`PtrKey` requires `T: Sized`"**: you added `T: Sized` somewhere. Remove it. `PtrKey<'t, T: ?Sized>` is the spec. +- **Pre-commit hook rejection on a `/* */` block**: you accidentally edited whitespace inside a frozen Scala block. Read the hook's diff output and revert the block's content byte-for-byte. +- **"I want to port `declare_function_return_type` because the body is 3 lines"**: don't. Gotcha 10. Every method body stays `panic!()` until Slab 8. If you port one, port none. +- **"I want to switch from `std::HashMap` to `hashbrown::HashMap` for speed"**: don't. Gotcha 7. `std::HashMap` is correct and sufficient for Slab 6. Perf optimization is Slab 9+. +- **"I want to fix the `InstantiationBoundArgumentsT` stub in `hinputs_t.rs`"**: don't. Gotcha 12. That's Slab 7/8. +- **"I want to touch `names.rs` / `types.rs` / `templata.rs` / `env/*.rs` / `ast/*.rs`"**: don't. Earlier slabs are frozen. If you think one of those files needs a change for Slab 6 to work, the shape of Slab 6 probably shifted — ask the senior first. +- **"A sub-compiler file still uses `&mut CompilerOutputs<'_, '_>` and I want to flip it to `<'s, 't>`"**: leave it. The elided-lifetime form is fine at function signatures — Rust infers `<'s, 't>` from the caller. Only flip if the compiler complains, and even then prefer `panic!("Unimplemented: Slab 8")` on the body over real signature rework. + +## Where to file questions + +- **Design (field layout, enum shape, arena lifetime)**: `quest.md` Part 4 is the spec; this doc covers the detailed how. If they disagree, **this doc wins** (because it folds in Slab 4's env override that quest.md §4.1 doesn't reflect). If both agree on a point and you still disagree, ask the senior. +- **Scala semantics**: the `/* */` block is the spec. Cross-reference with the other Scala blocks at lines 57–136 for the full mutable-collection shape. +- **PtrKey subtleties** (Hash impl, `?Sized`, manual Copy): quest.md §4.2 is verbatim. Cross-reference with `src/typing/typing_interner.rs` for the analogous pointer-identity pattern used in the interner (different use case, similar philosophy). +- **Hook rejections**: read the hook's diff output. Usually accidental whitespace inside `/* */`. + +## Final advice + +This is a narrow slab. `PtrKey` is ~35 lines of module code; `DeferredActionT` is a 2-variant enum; `CompilerOutputs` is a 23-field struct + an empty-constructor. The hardest part is **not porting method bodies** — the temptation is real because several of the ~50 existing method stubs have trivial Scala implementations sitting right there in the `/* */` block. Resist. Method bodies are Slab 8. + +Two carve-outs to remember: +1. **Env overrides from Slab 4.** Quest.md §4.1's `&'s IEnvironmentT` becomes `&'t IInDenizenEnvironmentT` in every env-map value. Gotcha 1 is critical. +2. **AASSNCMCX doesn't apply.** `CompilerOutputs` is stack-owned; `HashMap` / `Vec` / `VecDeque` / `HashSet` are all fine. Gotcha 2. + +After Slab 6, the only remaining data-definition slab is Slab 7 (HinputsT + Compiler shell + `run_typing_pass`). Slab 8 is the signature-rewrite pass.

A senior engineer has been moving through the typing pass one "slab" at a time per `quest.md` §12.

HinputsT and Compiler are largely already in place — you're verifying their shape and adding the entry-point glue, not rebuilding them. + +This is the **smallest slab** so far — budget 1–2 hours focused. The bulk of the typing pass's "real work" is Slab 8 (every existing panic-stub method gets a real signature) and Slab 9+ (test-driven body migration). Slab 7 just lays the entry-point landing pad so Slab 8 has somewhere to wire bodies into. + +**Read these first in this order**, then come back: + +1. `quest.md` — **Part 10** (§§10.1–10.2, "Driving The Pass") is the spec for `run_typing_pass`. Also §§2.1–2.4 (the god struct), 11 (Invariants Summary — short, useful refresher), 12.1 Slab-7 paragraph. +2. `TL-HANDOFF.md` at repo root — the file-layout standards section, the post-Slab-5/6 state. Notably: **`Compiler<'s, 'ctx, 't>` already exists with its 4 fields and a `new()` constructor** — you don't rebuild it, you just verify it compiles after Slab 6 changes and add two new methods to it. +3. `FrontendRust/docs/migration/handoff-slab-6.md` §§"What 'done' looks like" + Gotchas 1/2/4. You'll be calling `CompilerOutputs::new()` and using `DeferredActionT` from your panic-stub method bodies. +4. `Luz/shields/ArenaAllocatedStructsShouldNotContainMallocdCollections-AASSNCMCX.md` — same as Slab 6: `HinputsT` is conceptually `'t`-arena-allocated, but the current Vec/HashMap fields are an acknowledged deviation per the Scala-parity rule. **You don't fix this in Slab 7** — it's body-migration territory. +5. This doc. + +You shouldn't need to read the Scala source externally — every Scala definition is already embedded inline in the `/* ... */` blocks in `compiler.rs`, `compilation.rs`, and `hinputs_t.rs`. If a block is ambiguous, ask; don't guess. + +--- + +## The big picture: why Slab 7 exists + +The typing pass needs an entry point. In Scala, that's `Compiler.evaluate(codeMap, packageToProgramA): Result[HinputsT, ICompileErrorT]` — a method on `Compiler` that: + +1. Builds the `globalEnv` from `packageToProgramA`. +2. Builds a `CompilerOutputs()` accumulator. +3. Walks the program's denizens, calling sub-compiler methods that mutate `coutputs`. +4. Drains the deferred-evaluation queue. +5. Materializes a `HinputsT` from the populated `coutputs`. +6. Returns `Ok(hinputs)`. + +Per `quest.md` §10.1, the Rust analog is a **free function** (not a `Compiler` method) called `run_typing_pass`. Why a free function? Because in Rust the `Compiler` struct is built from references (`&'ctx ScoutArena<'s>`, `&'ctx TypingInterner<'s, 't>`, etc.) that the caller already owns. Wrapping the construction-and-drive in a free function makes the lifetime relationships obvious: the caller holds the arenas across the call; `run_typing_pass` builds a `Compiler` and `CompilerOutputs` internally and returns the `HinputsT` (which itself holds `'s` and `'t` refs into the caller's arenas). + +The Scala `Compiler.evaluate` itself becomes (in Rust) a `Compiler::compile_program(&self, &mut coutputs, program_a)` method — but that's body work. Slab 7 only stubs it so `run_typing_pass` has something to call. Same for `drain_all_deferred`. + +By the end of Slab 7: + +- `cargo check --lib` passes with 0 errors. +- `src/typing/compilation.rs` (or a new `src/typing/run_typing_pass.rs`, your call — see Gotcha 5) gets `pub fn run_typing_pass<'s, 'ctx, 't>(…) -> Result, ICompileErrorT<'s, 't>> where 's: 't { panic!(…) }`. Body is a panic-stub; signature matches quest.md §10.1 modulo the `ICompileErrorT` naming (current Rust spells it `ICompileErrorT`, not `CompileErrorT`). +- `src/typing/compiler.rs` gains two new methods on `Compiler`: `pub fn compile_program(&self, coutputs: &mut CompilerOutputs<'s, 't>, program_a: &'s ProgramA<'s>) -> Result<(), ICompileErrorT<'s, 't>>` and `pub fn drain_all_deferred(&self, coutputs: &mut CompilerOutputs<'s, 't>)`. Each in its own one-fn impl block, body `panic!()`. These are landing pads for Slab 8. +- `src/typing/hinputs_t.rs`: the two `()` placeholder slots in `InstantiationReachableBoundArgumentsT.citizen_rune_to_reachable_prototype` and `InstantiationBoundArgumentsT.rune_to_bound_prototype` flip to `&'t PrototypeT<'s, 't>` (the comment block says "broken upstream" but Slab 3 fixed it — `PrototypeT` is monomorphic now). The `make()` helper's matching parameter type also flips. +- `HinputsT<'s, 't>` itself is **already done** (real fields exist with the AASSNCMCX-deviation comment); you confirm the shape and optionally add `#[derive(Debug)]` + a panic-stub `HinputsT::new()` constructor for Slab 8 to wire from `coutputs`. +- `ICompileErrorT<'s, 't>` stays `_Phantom` — known residual; bodies don't construct error variants yet (everything panics), so the placeholder is fine. See Gotcha 6. +- All Scala `/* */` blocks unchanged byte-for-byte. + +**What Slab 7 is NOT:** + +- No body migration. `run_typing_pass`, `compile_program`, `drain_all_deferred` all `panic!()`. +- No `HinputsT::new(coutputs)` real implementation — Slab 8 wires the materialization from `CompilerOutputs` fields. +- No `ICompileErrorT` variant filling — known residual; Slab 9+ as bodies need them. +- No `InstantiationBoundArgumentsT` HashMap → arena-slice conversion. Vec/HashMap stay. +- No `Compiler.evaluate` method porting — that's Slab 8 (when porting, it folds into `compile_program` per the new Rust naming). +- No `TypingPassCompilation::expect_compiler_outputs` rewiring — the existing panic-stub stays panic-stubbed; Slab 8 wires it to call `run_typing_pass` once `run_typing_pass`'s body is real. +- No HinputsT method bodies (`lookup_struct`, `lookup_interface`, `lookup_edge`, etc. — all stay panic-stubbed). +- No god-struct macro-method migration (`generate_function_body_lock_weak`, `dispatch_function_body_macro`, etc. — all Slab 8). + +--- + +## What's already in place (don't duplicate; don't delete) + +### `src/typing/compiler.rs` (1799 lines) + +`Compiler<'s, 'ctx, 't>` is real and matches quest.md §2.1: + +```rust +pub struct Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub scout_arena: &'ctx ScoutArena<'s>, + pub typing_interner: &'ctx TypingInterner<'s, 't>, // Slab-4 two-lifetime flip applied + pub keywords: &'ctx Keywords<'s>, + pub opts: &'ctx TypingPassOptions<'s>, +} + +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn new(/* same 4 args */) -> Self { Compiler { … } } +} +``` + +The rest of the file (~1700 lines) is panic-stubbed free-function methods that Slab 8 will lift into `impl Compiler` blocks. **Don't touch any of those.** Specifically: `Compiler::evaluate(code_map: (), package_to_program_a: ()) -> () { panic!(…) }` at line 800 is the Scala analog of what becomes `compile_program` in Rust naming — leave it as a panic-stubbed free fn.

Drop the parametric phantoms; reference by `&'t`. The two stub-comment lines acknowledging the broken-upstream-blocker should be removed since the upstream is now fixed. + +For everything else in Slab 7, the rules are the same as prior slabs. Quick reference for the entry-point signature: + +| Scala | Rust | +|---|---| +| `(codeMap: FileCoordinateMap[String], packageToProgramA: PackageCoordinateMap[ProgramA])` (Scala `Compiler.evaluate` sig) | `program_a: &'s ProgramA<'s>` (a single ProgramA per package; quest.md §10.1 simplification) | +| `Result[HinputsT, ICompileErrorT]` | `Result, ICompileErrorT<'s, 't>>` | +| `(opts: TypingPassOptions, interner: Interner, keywords: Keywords)` (Scala `Compiler` constructor args) | `(scout_arena: &'ctx ScoutArena<'s>, typing_interner: &'ctx TypingInterner<'s, 't>, keywords: &'ctx Keywords<'s>, opts: &'ctx TypingPassOptions<'s>)` | + +### Derives + +- `HinputsT<'s, 't>`: optionally add `#[derive(Debug)]`.

If a field doesn't derive `Debug`, skip the `Debug` derive on `HinputsT` for now and flag as a Slab 8 cleanup. **Don't try to derive `Copy` / `Clone` / `PartialEq` / `Eq` / `Hash`** — Scala overrides `equals`/`hashCode` to `vfail`/`vcurious` on HinputsT (it's too big to compare). +- `InstantiationBoundArgumentsT<'s, 't>` / `InstantiationReachableBoundArgumentsT<'s, 't>`: keep whatever derives (or lack thereof) they currently have — don't add `Debug` here either, since `IRuneS` deriving might break. +- `Compiler<'s, 'ctx, 't>`: no derives — it owns references and method pointers conceptually; comparison/hashing/printing are meaningless. + +### `where 's: 't` bound + +Already on `Compiler` and `HinputsT`.

The §10.1 sketch builds `HinputsT { function_definitions: typing_interner.alloc_slice_iter(…), … }` with field names that **don't match** the current Scala-parity-named `HinputsT` (`functions`, `structs`, etc.). Wiring the materialization means resolving field-name mapping AND deciding whether to keep `Vec<…>` (Scala parity, current code) or flip to `&'t [...]` (quest.md §10.1 sketch + AASSNCMCX). That decision is a body-migration concern; Slab 7 punts. +2. `Compiler::compile_program` and `Compiler::drain_all_deferred` are themselves panic-stubs — calling them from `run_typing_pass`'s body wouldn't make `run_typing_pass` actually work, just shift the panic site one level. Cleaner to make the whole entry point panic with one informative message. + +The point of writing `run_typing_pass` in Slab 7 is establishing the **signature** as the lifetime-relationships anchor — every type the body would touch (`ScoutArena<'s>`, `TypingInterner<'s, 't>`, `Keywords<'s>`, `TypingPassOptions<'s>`, `ProgramA<'s>`, `HinputsT<'s, 't>`, `ICompileErrorT<'s, 't>`) appears in the signature. If any lifetime bound is wrong, you'll find out in Slab 7 instead of mid-Slab-8. + +--- + +## The `compile_program` / `drain_all_deferred` stubs + +Both go in `src/typing/compiler.rs`, each in their own one-fn `impl` block, near the top of the file (after `Compiler::new`). Per the TL-HANDOFF file-layout convention. + +```rust +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn compile_program( + &self, + coutputs: &mut CompilerOutputs<'s, 't>, + program_a: &'s ProgramA<'s>, + ) -> Result<(), ICompileErrorT<'s, 't>> { + panic!("Unimplemented: Compiler::compile_program — Slab 8"); + } +} + +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> +where 's: 't, +{ + pub fn drain_all_deferred( + &self, + coutputs: &mut CompilerOutputs<'s, 't>, + ) { + panic!("Unimplemented: Compiler::drain_all_deferred — Slab 8"); + } +} +``` + +**No Scala `/* */` block companion** — these are Rust-side methods derived from the Scala-side `Compiler.evaluate` body. The original `Compiler.evaluate` Scala block stays at line ~800 with its existing `pub fn evaluate(code_map: (), package_to_program_a: ()) -> () { panic!(…) }` Rust stub. You're adding **new methods next to it**, not replacing it. + +`evaluate` will be deleted (or rewritten as a thin wrapper around `compile_program`) in Slab 8 once bodies migrate.

Per quest.md §1.5 +> // HinputsT is 't-arena-allocated, which per AASSNCMCX means these should later become +> // arena slices, not std Vec/HashMap. Keeping Vec/HashMap for now to match Scala shape; +> // revisit during body migration. + +**Slab 7 leaves this deviation in place.** Don't try to flip `Vec` → `&'t [X]` — doing so requires materialization logic at HinputsT-construction time (which is Slab 8 work). Body migration revisits. + +If you want to add `#[derive(Debug)]` to `HinputsT` and find it doesn't derive cleanly because of one of the field types, skip the derive and add a one-line `// TODO: derive Debug — blocked on Slab N: FooT doesn't derive Debug` comment. Don't unblock by adding Debug to a Slab-2/3/4/5 type — those slabs are frozen. + +### Gotcha 4: `Compiler.evaluate` panic-stub stays — don't delete it + +The existing `pub fn evaluate(&self, code_map: (), package_to_program_a: ()) -> ()` at compiler.rs line 800 is the Scala analog of what'll become `compile_program` in Rust naming. Slab 8 will either rename `evaluate` → `compile_program` (folding the bodies) or delete `evaluate` entirely. **Slab 7 leaves it untouched.** Add `compile_program` and `drain_all_deferred` as **new sibling methods** in their own impl blocks. Two slightly-overlapping panic stubs is fine; the panic message ("Unimplemented: Compiler::compile_program — Slab 8") tells the reader which is which. + +### Gotcha 5: File placement for `run_typing_pass` — `compilation.rs` vs new `run_typing_pass.rs` + +Two reasonable choices: + +**Option A: put `run_typing_pass` in `src/typing/compilation.rs`** (alongside `TypingPassOptions` and `TypingPassCompilation`). Pros: it's the existing pass-coordination module; `TypingPassCompilation::expect_compiler_outputs` will eventually call `run_typing_pass`. Cons: `compilation.rs` is small (181 lines) and currently does the higher-typing wrapping; mixing the typing-pass entry with the compilation orchestration makes the file's role less clean. + +**Option B: new `src/typing/run_typing_pass.rs` file.** Pros: clean separation — one file = one concern. Cons: a new ~30-line file just for one panic-stub fn feels like overkill. + +**Recommendation: Option A.** Put it in `compilation.rs`, near the top (above `TypingPassCompilation` impl block). Add a `pub use compilation::run_typing_pass;` to `src/typing/mod.rs` for easy import. + +Why: a one-fn standalone file is awkward, and `TypingPassCompilation` already lives in `compilation.rs`, so the entry point being its sibling is the natural reading order — caller calls `TypingPassCompilation::expect_compiler_outputs(…)` (today panics), which in Slab 8 will internally call `run_typing_pass(…)`. Putting both in the same file makes that call shape easy to scan. + +### Gotcha 6: Don't wire `TypingPassCompilation::expect_compiler_outputs` to call `run_typing_pass` yet + +The existing panic-stub at compilation.rs ~line 156 — `pub fn expect_compiler_outputs(&mut self) -> ()` — will eventually call `run_typing_pass`. **Don't wire it in Slab 7.** Why: + +- Both methods panic. Wiring just shifts the panic site. +- `TypingPassCompilation::expect_compiler_outputs` needs to provide the `scout_arena` / `typing_interner` / `keywords` / `opts` / `program_a` that `run_typing_pass` takes. The wiring requires real thread-through of those references from `TypingPassCompilation`'s current state, which is Slab 8 plumbing. + +Slab 7: leave `expect_compiler_outputs` as `panic!("…")`. Slab 8 wires it. + +### Gotcha 7: `_phantom` field on `InstantiationReachableBoundArgumentsT` should be deleted, not preserved + +After flipping `()` → `&'t PrototypeT<'s, 't>` in `InstantiationReachableBoundArgumentsT.citizen_rune_to_reachable_prototype`, the `_phantom: PhantomData<(&'s (), &'t ())>` field becomes redundant — both `'s` (via `IRuneS<'s>`) and `'t` (via `&'t PrototypeT<'s, 't>`) are now anchored by real fields. **Delete the `_phantom` field.** Same for the matching TODO comment. + +`InstantiationBoundArgumentsT` doesn't have a `_phantom` (its three Vec-fields anchor both lifetimes already), so nothing to delete there. + +### Gotcha 8: Pre-commit hook on `/* */` blocks (unchanged) + +Same as every prior slab. `.claude/hooks/check-scala-comments` does exact-match comparison on every `/* ... */` block. Rules for Slab 7: + +- Don't edit inside any `/* */` block. +- You can delete/edit Rust comments **outside** `/* */` blocks (specifically: the `// TODO: stub — replace Vec…` lines around `InstantiationReachableBoundArgumentsT` and `InstantiationBoundArgumentsT`, since those are stale post-Slab-3 and you're cleaning them up). +- You can add new Rust definitions (the `compile_program` impl block, the `drain_all_deferred` impl block, the `run_typing_pass` fn) — new code outside Scala blocks is unrestricted. + +### Gotcha 9: `pub fn make(…)` at hinputs_t.rs line 37 is NOT inside an `impl` block + +It's a top-level `pub fn` (per the slice-pipeline output). Scala's `object InstantiationBoundArgumentsT { def make(…) }` is a companion-object factory; the Rust analog would be `impl InstantiationBoundArgumentsT { pub fn make(…) }`. **Don't lift it into an impl block in Slab 7.** Slab 8 does the lift as part of method-signature rewrite. You're only updating the parameter type to flip `()` → `&'t PrototypeT`. + +### Gotcha 10: No method body migration on HinputsT + +The bottom of `hinputs_t.rs` has ~10 panic-stubbed lookup methods (`lookup_struct`, `lookup_struct_by_template`, `lookup_interface`, `lookup_edge`, etc.) with Scala bodies in `/* */` blocks. **All stay panic-stubbed.** Slab 8. + +Same for the `subCitizenToInterfaceToEdge` post-hoc-computed map: Scala builds it in the case-class body from `interfaceToSubCitizenToEdge` via a 5-line nested-loop. The Rust-side equivalent would be a `HinputsT::new(…)` constructor that does the inversion. **Don't write that constructor in Slab 7.** Materialization is Slab 8. The current code keeps `sub_citizen_to_interface_to_edge` as a separate field that callers populate, which works for the data-def shape we need now. + +If you do add a `HinputsT::new(…)` constructor in Slab 7, make it panic-stubbed and take only the obvious args (no inversion logic): +```rust +impl<'s, 't> HinputsT<'s, 't> { + pub fn new(/* … all 11 fields by value … */) -> Self { + panic!("Unimplemented: HinputsT::new — Slab 8 wires from CompilerOutputs"); + } +} +``` + +This is optional — Slab 8 can construct HinputsT via a struct literal directly, no factory needed. Skip the `new()` if you'd rather keep Slab 7 minimal. + +--- + +## Step-by-step plan + +### Step 1: Confirm starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-7.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-7.txt +``` + +Must print `0`.

But it deliberately left the ~54 method stubs as **private free-fns** at file scope with panic bodies and partial signatures. Example from the current file state: + +```rust +fn lookup_function<'s, 't>(signature: SignatureT<'s, 't>) -> Option> { + panic!("Unimplemented: lookup_function"); +} +/* + def lookupFunction(signature: SignatureT): Option[FunctionDefinitionT] = { + signatureToFunction.get(signature) + } +*/ +``` + +Several things are wrong with that stub for real use: +- It's a free fn, not a method on `CompilerOutputs`. Callers can't reach it via `coutputs.lookup_function(...)`. +- `SignatureT<'s, 't>` is passed by value instead of `&'t SignatureT<'s, 't>` (Slab 3 interned). +- Return type is `Option>` (owned) instead of `Option<&'t FunctionDefinitionT<'s, 't>>` (arena ref). +- No `&self` receiver. + +Slab 8 fixes all three across every method. Each stub becomes: + +```rust +impl<'s, 't> CompilerOutputs<'s, 't> +where 's: 't, +{ + pub fn lookup_function( + &self, + signature: &'t SignatureT<'s, 't>, + ) -> Option<&'t FunctionDefinitionT<'s, 't>> { + panic!("Unimplemented: Slab 10 — body migration"); + } +} +/* + def lookupFunction(signature: SignatureT): Option[FunctionDefinitionT] = { + signatureToFunction.get(signature) + } +*/ +``` + +Same panic, but a real method with real parameter and return types. Slab 10+ can now migrate bodies (`self.signature_to_function.get(&PtrKey(signature)).copied()`) one at a time without ever having to re-shape the method. + +**Why not migrate bodies while you're there?** Because consistency wins. Two rules-of-thumb in this project: +- If one method gets bodies and the next doesn't, the next reader assumes they all do (or none do) and gets confused. Slab 8 gets *zero*; Slab 10 gets *all*. +- Signature-rewrite is mechanical (follow the translation table). Body migration needs judgment (which field is this accessing? does the body still make sense post-`PtrKey`? etc.). Mixing the two blows up the review burden. + +See Slab 6 Gotcha 10 for the full argument. Resist the temptation on obvious one-liners. + +**By the end of Slab 8:** + +- `cargo check --lib` passes with 0 errors. +- `src/typing/compiler_outputs.rs`: + - All 54 free-fn stubs at file scope are **deleted**.

Scala `/* */` block unchanged. + +--- + +## Gotchas + +### Gotcha 1 (critical): envs are `&'t IInDenizenEnvironmentT`, not `&'s IEnvironmentT` + +Same rule as Slab 6 Gotcha 1. Every env parameter in every method (there are ~10 of them — `declare_function_inner_env`, `declare_function_outer_env`, `declare_type_outer_env`, `declare_type_inner_env`, `get_outer_env_for_type`, `get_inner_env_for_type`, `get_inner_env_for_function`, `get_outer_env_for_function`) becomes `&'t IInDenizenEnvironmentT<'s, 't>`. Never `&'s IEnvironmentT`. **Not even once.** If quest.md §§ on envs show `&'s IEnvironmentT`, quest.md is out-of-date post-Slab-4. + +The one exception is `get_env_for_function_signature`, which returns the specific `FunctionEnvironmentT` (a concrete env type, not the wrapper enum). That stays `&'t FunctionEnvironmentT<'s, 't>`. + +### Gotcha 2: `IdT<'s, 't>` is by value, not `&'t IdT` + +Slab 2 made `IdT` monomorphic and `Copy` with pointer-identity `Hash`/`Eq`. Pass it by value everywhere. This differs from `PrototypeT` / `SignatureT` / arena-allocated structs which are passed by `&'t`. + +Easy memory trick: the `PtrKey<'t, IdT<'s, 't>>` fields in `CompilerOutputs` wrap `IdT` by value (via `&'t IdT` inside the `PtrKey`, but the public boundary is by value). When you're building method signatures, just take `IdT` by value. + +### Gotcha 3: arena refs (`&'t`) on definition types + +Scala returns `StructDefinitionT` or `FunctionDefinitionT` from lookups; that's the JVM hiding the fact that these live on the heap and are passed by reference. Rust is explicit — definition types are arena-allocated (Slab 3/5) and passed by `&'t X<'s, 't>`. Every lookup returns `Option<&'t X<'s, 't>>` or `&'t X<'s, 't>` (for `vassertSome`-style lookups). Every "add" takes `&'t X<'s, 't>` as the parameter. + +The internal HashMap fields in `CompilerOutputs` already store `&'t X<'s, 't>` values (Slab 6). Method signatures match. + +### Gotcha 4: `DeferredActionT` peek returns a ref + +`peek_next_deferred_function_body_compile(&self) -> Option<&DeferredActionT<'s, 't>>`. Not `Option>`. The action stays in the `VecDeque`; peek borrows. `pop_front()` would move-out, but that's the "mark compiled" method's job (Slab 10 body migration). + +### Gotcha 5: `add_instantiation_bounds` needs `TypingInterner`, not `Interner` + +The Scala `addInstantiationBounds(interner: Interner, ...)` method's `Interner` is the typing-side canonicalizer in the Rust split. Use `&'t TypingInterner<'s, 't>` as the parameter type. + +Why not `&'ctx Interner<'s>` (scout)? Because the body reaches into `TemplataCompiler.getRootSuperTemplate(interner, callingTemplateId)` where `callingTemplateId` is typing-side (`IdT[ITemplateNameT]`). The interner used for typing-side canonicalization is `TypingInterner`. + +If Slab 10 body migration discovers it actually needs the scout interner, patch then. For now, `&'t TypingInterner<'s, 't>` compiles and matches the slab-4/6 convention. + +### Gotcha 6: `HashMap` return in `get_instantiation_name_to_function_bound_to_rune` + +Scala `getInstantiationNameToFunctionBoundToRune(): Map[IdT[IInstantiationNameT], InstantiationBoundArgumentsT[IFunctionNameT, IImplNameT]] = instantiationNameToInstantiationBounds.toMap` returns an immutable copy of the internal map. + +Rust return type: `HashMap>, &'t InstantiationBoundArgumentsT<'s, 't>>` — **matches the internal field type from Slab 6**, not Scala's `Map[IdT, InstantiationBoundArgumentsT]` directly. + +Why: the internal map is `HashMap, &'t InstantiationBoundArgumentsT>`. Slab 10 body migration will do `self.instantiation_name_to_bounds.clone()` — cloning the `HashMap` is cheap (`PtrKey` is `Copy`, `&'t _` is `Copy`, so `HashMap` cloning is O(n) memcpy of the bucket array with no per-entry clones). The alternative — stripping `PtrKey` and returning `HashMap, &'t InstantiationBoundArgumentsT<'s, 't>>` — would force a re-key-build on every call, and we'd lose the pointer-identity semantics that `PtrKey` provides. + +Keep `PtrKey` in the return. Slab 10 will decide whether callers actually need it or whether an iterator is better — don't pre-optimize. + +### Gotcha 7: `pub fn`, not `fn` + +All Slab 6 free-fn stubs are private (`fn`). Scala `def` is public by default. Slab 8's lifted methods get `pub fn`. Don't leave them private — callers in other files need to reach them once Slab 10 bodies migrate. + +### Gotcha 8: bodies stay `panic!()` — no exceptions + +Gotcha 10 from Slab 6, but with the slab number bumped. You will be tempted. Several of the 54 methods have Scala bodies that are one-liners (`signatureToFunction.get(signature)`, `returnTypesBySignature += (sig -> ret)`, `kindExports += KindExportT(...)`). **Don't port them.** Reasons: + +- Consistency: if you port three trivial ones, the reviewer has to trust that the other 51 are also correctly left alone. If you port zero, the reviewer's job is O(1). +- Semantics have subtle `PtrKey`-wrapping decisions (see `lookup_function`: is it `.get(&PtrKey(signature))` or `.get(signature)` or `.values().find(...)`?). Getting those wrong means Slab 10 body migration has to audit your work alongside its own. +- Slab 10 is the body-migration slab; it'll handle all 54 together in one reviewable pass. + +Bump the panic message from `"Unimplemented: "` to `"Unimplemented: Slab 10 — body migration"` so the next reader knows exactly what's deferring. + +### Gotcha 9: one-fn impl blocks per TL-HANDOFF convention + +Each lifted method gets its own `impl<'s, 't> CompilerOutputs<'s, 't> where 's: 't { pub fn foo(...) -> ... { ... } }` block. Do NOT consolidate all 54 methods into a single giant impl block. Why: each method has an adjacent Scala `/* def ... */` anchor block below it; one-fn-per-impl preserves the method-to-anchor adjacency. + +This matches the style Slab 7 established for `compile_program` and `drain_all_deferred` on `Compiler`, and Slab 6's `CompilerOutputs::new`. + +### Gotcha 10: Scala `/* */` blocks are frozen — pre-commit hook enforces + +Same rule as every prior slab. `.claude/hooks/check-scala-comments` does exact-match comparison on every `/* ... */` block in the file. If your editor auto-indents whitespace inside a Scala block while you're editing the Rust stub directly above it, the pre-commit hook will bounce. Revert the whitespace and retry. + +You're deleting Rust stubs and writing new impl blocks above Scala anchors. The Scala content should never change. + +### Gotcha 11: no downstream breakage expected + +The Slab 6 free-fn stubs are private (`fn`, not `pub fn`), take value-typed params, and have panic bodies. Nothing in the codebase currently calls them — they aren't reachable symbols. Lifting them into `impl CompilerOutputs` doesn't break any existing call sites (there are none). + +This means **every compile error you see after a lift is a signature mistranslation**, not a downstream-call-site issue. If `cargo check --lib` flags an error, re-read the Scala block and fix the translation. Don't add `panic!("Unimplemented: Slab 10")` patches in other files — nothing should need them. + +### Gotcha 12: `#[allow(unused_variables, unused_imports)]` is project-level + +The crate sets `#![allow(unused_variables, unused_imports)]`, so you'll get no warnings for params that aren't read in the panic body. This is intentional during mid-migration. Don't prefix unused params with `_` — Slab 10 will need them by name. + +--- + +## Step-by-step plan + +### Step 1: Confirm starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-8.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-8.txt +``` + +Must print `0`. If not, stop and ask the senior. + +### Step 2: Lift in file order + +Walk the 54 stubs top-to-bottom in `src/typing/compiler_outputs.rs`. The first stub (`count_denizens`) is around line 229; the last (`get_function_externs`) is around line 842. For each stub: + +1. Read the Scala `/* def ... */` block directly beneath it. +2. Classify the receiver (`&self` or `&mut self`) using the defaults list above. Verify against the Scala body — look for `+=`, `-=`, `.put(...)`, `.remove(...)` on field names. +3. Translate each parameter and return type using the translation-rules table. Pay particular attention to env params (Gotcha 1), arena-ref returns (Gotcha 3), and `IdT` by-value (Gotcha 2). +4. Replace the single-line free-fn stub with a one-fn `impl` block: + ```rust + impl<'s, 't> CompilerOutputs<'s, 't> + where 's: 't, + { + pub fn ( + &self-or-&mut-self, + // ... params on their own lines ... + ) -> { + panic!("Unimplemented: Slab 10 — body migration"); + } + } + ``` +5. Leave the Scala `/* */` block directly below untouched. + +### Step 3: Incremental verification + +After every ~10 stubs, run: + +```bash +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-8.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-8.txt +``` + +Fix any errors before moving on.

Inside signatures, definition types appear as HashMap *values*, not keys. Keys are `PtrKey<'t, IdT>` / `PtrKey<'t, SignatureT>` / etc. Re-check whether the error is complaining about a parameter or a return type; keys in returns should be wrapped. +- **"`'s` may not live long enough"**: missing `where 's: 't` on the `impl` header. Every `impl` block over `CompilerOutputs` needs it. +- **"cannot find type `PtrKey`"**: Slab 6 already added `use crate::typing::ptr_key::PtrKey;` at the top of the file — verify it's still there. If missing, add it. +- **"mismatched types: expected `&'t IInDenizenEnvironmentT`, found `IInDenizenEnvironmentT`"**: you translated an env param as a value type.

One fn per impl block, adjacency to Scala anchor preserved. +- **"`KindT` / `InterfaceTT` / `StructTT` — value or `&'t`?"**: check Slab 3 — most are `Copy`-friendly tagged pointers. Default by value.

See Gotcha 5. +- **"Scala body has a `vassert` I'm not sure how to classify — is it mutation?"**: `vassert` is just an assertion; doesn't mutate. Look past it to the rest of the body. If the body otherwise has no `+=`/`.put(...)`, it's `&self`. +- **"pre-commit hook rejection on a `/* */` block"**: you accidentally edited whitespace inside a Scala block.

Ask the senior if you disagree. + +## Where to file questions + +- **Design**: `FrontendRust/docs/migration/handoff-slab-6.md` is the spec for the struct shape this slab lifts methods onto. If there's disagreement between this doc and Slab 6, **Slab 6 wins** on struct shape; **this doc wins** on method signatures (because Slab 6 explicitly deferred method signatures to Slab 8). +- **Scala semantics**: each Scala `/* def ... */` block beneath a stub is the spec. The body tells you receiver kind (`+=` → `&mut self`). The signature tells you parameter and return types. +- **Hook rejections**: read the hook's diff output. Usually accidental whitespace inside `/* */`. + +## Final advice + +This is narrow, mechanical work. The hardest part is resisting body migration on obvious one-liners. Resist. Slab 10 owns bodies. + +Two facts to anchor you: +1. **Every method body in this slab is `panic!("Unimplemented: Slab 10 — body migration");`**. No exceptions. +2. **Every env param is `&'t IInDenizenEnvironmentT<'s, 't>`**. Slab-4 override, non-negotiable. + +If you get those two right and follow the translation table, the 54 stubs become 54 one-fn impl blocks in a few hours. If you find yourself writing non-panic code in a method body, stop and re-read Gotcha 8. + +After Slab 8, the next data-def-adjacent slab is Slab 9 (`templata_compiler.rs`, 35 stubs, with the open question of whether to host as unit struct or lift into `impl Compiler`).

Why? + +1. The god-struct refactor pushed every sub-compiler's methods onto `Compiler` so `Compiler` holds `scout_arena`, `typing_interner`, `keywords`, `opts` and methods access them via `&self.typing_interner` etc. instead of passing them as parameters. +2. The already-lifted 14 impl blocks at the tail of the same file establish the pattern for this file specifically. +3. Several "static" Scala methods (like `getFunctionTemplate(id: IdT[IFunctionNameT])`) *appear* stateless but in Rust require the typing interner to re-canonicalize the rebuilt `IdT`. Passing `&self` gives them access to `self.typing_interner` without adding a parameter. +4.

The `create_rune_type_solver_env` method takes `parentEnv: IInDenizenEnvironmentT` — translate to `parent_env: &'t IInDenizenEnvironmentT<'s, 't>`. **Never** `&'s IEnvironmentT`. + +### Gotcha 2: drop `interner: Interner` and `keywords: Keywords` parameters + +Scala methods on the `object TemplataCompiler` take these as explicit parameters because Scala objects don't have a `this` to store infrastructure state. In Rust, `Compiler<'s, 'ctx, 't>` holds `typing_interner: &'ctx TypingInterner<'s, 't>` and `keywords: &'ctx Keywords<'s>` as fields. Methods access via `self.typing_interner` / `self.keywords`. + +**Remove both from the Rust parameter list when lifting.** Slab 10 body migration will use `self.typing_interner.intern_...(...)` in the body. + +Exception: `getRootSuperTemplate(interner: Interner, id: IdT[INameT])` also takes interner. Drop it; body uses `self.typing_interner`. + +### Gotcha 3: `IBoundArgumentsSource` is a marker trait, not a pattern-matchable enum + +The current Rust type is `pub trait IBoundArgumentsSource<'s, 't> {}` with two empty-impl unit structs. This is **dysfunctional** for the Scala body's pattern match: + +```scala +boundArgumentsSource match { + case InheritBoundsFromTypeItself => ... + case UseBoundsFromContainer(params, args) => ... +} +``` + +The trait has no `.variant()` method and the unit structs have no fields. A `&dyn IBoundArgumentsSource` can't be pattern-matched in Rust. + +**Slab 9 treatment:** pass as `bound_arguments_source: &'t dyn IBoundArgumentsSource<'s, 't>` in every signature. This compiles. Slab 10 body migration decides the fix — likely converting to an enum. + +Do NOT flip the trait to an enum in Slab 9. That's a breaking structural change that touches multiple files. Defer. + +### Gotcha 4: `IPlaceholderSubstituter` — probably doesn't exist yet as a Rust type + +Scala has `trait IPlaceholderSubstituter { def substituteForCoord(...): CoordT; ... }` — see the commented block at lines 842-860 showing the Scala trait definition. It's the return type of `getPlaceholderSubstituter` and `getPlaceholderSubstituterExt`. + +**Check first**: does `pub trait IPlaceholderSubstituter<'s, 't>` exist anywhere in the project? Grep for it. If yes, return `&'t dyn IPlaceholderSubstituter<'s, 't>`. + +If no, **define a minimal empty trait** in templata_compiler.rs just below the `IBoundArgumentsSource` definition: + +```rust +pub trait IPlaceholderSubstituter<'s, 't> {} +``` + +And place the Scala `/* trait IPlaceholderSubstituter { ... } */` block above it (moving the Scala anchor from its current commented-out position at lines 842-860 — actually don't move; leave the Scala blocks in place, just put the empty trait nearby). + +Hmm, that's a file-restructure. **Simpler alternative**: return `-> ()` as the Rust signature for `get_placeholder_substituter` and `get_placeholder_substituter_ext` in Slab 9, with a `// TODO: Slab 10 — return &'t dyn IPlaceholderSubstituter<'s, 't> after defining the trait` comment. This matches prior slabs' treatment of missing types (e.g. `ICompileErrorT`'s `_Phantom` placeholder). + +**Recommend**: use `-> ()` with a TODO comment. Keeps Slab 9 narrow. Slab 10 defines the trait and re-flips. + +### Gotcha 5: `IRuneTypeSolverEnv` — check if it exists + +Same question as Gotcha 4. Scala `createRuneTypeSolverEnv` returns `IRuneTypeSolverEnv`. Grep for `IRuneTypeSolverEnv` in the Rust codebase. + +If it exists (likely defined in `src/postparsing/` or similar), return `&'t dyn IRuneTypeSolverEnv<'s>` or similar. + +If not, return `-> ()` with a TODO comment. Don't define the trait in Slab 9. + +### Gotcha 6: `isSolved: IRuneS => Boolean` closure param + +`get_first_unsolved_identifying_rune` takes a closure parameter. Translate as: + +```rust +pub fn get_first_unsolved_identifying_rune( + &self, + generic_parameters: &'s [GenericParameterS<'s>], + is_solved: impl Fn(IRuneS<'s>) -> bool, +) -> Option<(&'s GenericParameterS<'s>, i32)> { + panic!("Unimplemented: Slab 10 — body migration"); +} +``` + +`impl Fn(...) -> ...` is the idiomatic Rust form for a non-mutating closure parameter. Don't use `Box` or `&dyn Fn` — `impl Fn` is cheaper and matches what a Slab 10 body would want. + +### Gotcha 7: methods that call other `TemplataCompiler` methods in their body + +Several substitute_* methods recursively call each other (e.g. `substituteTemplatasInCoord` calls `substituteTemplatasInKind`). In the Scala body these are plain static calls; in Rust they'll be `self.substitute_templatas_in_kind(...)`. + +**Slab 9 doesn't care** about body translations — body stays `panic!()`. But be aware: the recursion pattern in the Scala body is what justifies `&self` on methods that don't directly use Compiler state. Even a pure-id-transform method like `get_super_template` might call `get_name_template` internally (see its Scala body) — that call becomes `self.get_name_template(...)` in Slab 10. + +### Gotcha 8: `coutputs: &mut CompilerOutputs` not `&CompilerOutputs` — conservative choice + +Most substitute_* methods call `coutputs.addInstantiationBounds(...)` inside the body, which is a `&mut self` method on CompilerOutputs (Slab 8 made it `&mut self`). So the parameter must be `&mut CompilerOutputs`. + +Some methods (like `getReachableBounds`) only *read* from coutputs. **Conservative choice**: still pass `&mut CompilerOutputs<'s, 't>`. Two reasons: + +1. Slab 10 body migration may discover the read-only method also needs to mutate transitively (calling a substitute_* that mutates). +2. Rust's borrow checker is happier with consistent mut-ness across a function family — reduces Slab 10 refactoring. + +If you're confident a method is strictly read-only, use `&CompilerOutputs<'s, 't>`. Default to `&mut`. + +### Gotcha 9: `IRuneS`, `GenericParameterS`, `IRulexSR` are scout-side (`'s`), not typing-side (`'t`) + +These types live in `src/postparsing/`. They carry `<'s>` not `<'s, 't>`. Don't accidentally write `GenericParameterS<'s, 't>` — just `GenericParameterS<'s>`. + +When passed by reference, they borrow from the scout arena: `&'s GenericParameterS<'s>` (borrow and type both scout-side). + +### Gotcha 10: bodies stay `panic!()` — resist the temptation + +Same as Slab 8 Gotcha 8. Several methods here have trivial Scala bodies: + +- `getNameTemplate(name: INameT): INameT = name match { case x : IInstantiationNameT => x.template; case _ => name }` — 3 lines, tempting. +- `getFunctionTemplate(id: IdT[...])` — 4 lines of destructure+rebuild. + +**Don't port them.** Slab 10 migrates all 35 bodies together in a reviewable pass. Consistency wins. + +### Gotcha 11: one-fn impl blocks per TL-HANDOFF convention + +Same as Slab 8 Gotcha 9. Each method gets its own `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't { pub fn foo(...) { panic!(...) } }` block, adjacent to its Scala `/* def ... */` anchor. + +Do NOT consolidate 35 methods into a single impl block. The existing 14 impl blocks at lines 1034-1524 each wrap one method — follow that pattern. + +### Gotcha 12: Scala `/* */` blocks are frozen + +Same as every prior slab. Pre-commit hook `.claude/hooks/check-scala-comments` enforces byte-for-byte. + +### Gotcha 13: no downstream breakage expected + +The 35 free-fn stubs are private (`fn`, not `pub fn`), take no arguments, have panic bodies. Nothing calls them. Lifting doesn't create new call sites; Slab 10 wires callers. + +If you see a compile error after a lift, it's a signature mistranslation, not a downstream-call-site issue. + +--- + +## Step-by-step plan + +### Step 1: Confirm starting point + +```bash +cd /Volumes/V/Sylvan +cargo check --lib --manifest-path FrontendRust/Cargo.toml > /tmp/sylvan-slab-9.txt 2>&1 +grep -c "^error" /tmp/sylvan-slab-9.txt +``` + +Must print `0`. + +### Step 2: Quick traits check + +```bash +grep -rn "pub trait IPlaceholderSubstituter" FrontendRust/src +grep -rn "pub trait IRuneTypeSolverEnv" FrontendRust/src +``` + +If either exists, note the path and use the real trait in signatures. If neither exists, use `-> ()` with `// TODO: Slab 10 — return &'t dyn IFoo<'s, 't>` comments for the affected methods (Gotchas 4-5). + +### Step 3: Lift in file order, family-by-family + +The 35 stubs fall into 3 families (see "What's already in place" above). Lift top-to-bottom — the natural file order interleaves them slightly but it's fine. + +For each stub: + +1. Read the Scala `/* def ... */` block beneath. +2. Drop `interner` and `keywords` parameters (Gotcha 2). +3. Translate remaining params per the rules table. `IdT` by value, `&'t` on definition types, `&mut` on `coutputs`, `&'t dyn` on trait params. +4. Translate return type. +5.

The Scala source stays in the file as a commented-out `/* ... */` block above each corresponding Rust stub, so a reviewer can always see the original. +- We are focused on **the typing pass** (`FrontendRust/src/typing/`). The typing pass does type inference and type checking. +- There is a design doc at `/Volumes/V/Sylvan/quest.md` describing the three-arena lifetime model for this pass. **Read the "Status" section at the top.** Every typing type now carries lifetime parameters like `<'s, 't>` or `<'s, 'ctx, 't>`. (You don't need to understand the lifetime model in depth to do this task — but do skim §1.1–1.5 for vocabulary.) + +## Your task in one sentence + +**Add `use` statements to the top of each `.rs` file under `src/typing/` so that its references to other typing types actually resolve.** + +## Why this is needed + +The slice pipeline copied the Scala `import` lines into the `/* ... */` block at the top of each file (they live inside a Scala comment, not as Rust code). Rust doesn't see those — it needs real `use` statements. So right now, files reference types like `IdT`, `KindT`, `CoordT`, `RangeS` without having imported them, and the compiler yells: + +``` +error[E0425]: cannot find type `IdT` in this scope +error[E0425]: cannot find type `KindT` in this scope +error[E0425]: cannot find type `CoordT` in this scope +``` + +Before the handoff, the codebase had ~540 compile errors. Of those, roughly 350 are "cannot find type X in this scope" — all fixable by adding `use` lines. That's your job. + +## Current state (what's already done — don't redo) + +1. **Lifetime parameters** on every `pub struct`/`enum`/`trait` in `src/typing/**` have already been corrected (most take `<'s, 't>`; compilers take `<'s, 'ctx, 't>`). Don't touch type signatures. +2. **Module declarations** in `src/typing/mod.rs` and the sub-`mod.rs` files are complete. You don't need to add `pub mod foo;` anywhere. +3. `src/typing/types/types.rs` and `src/typing/names/names.rs` were done manually and already have most of what they need — they're the "leaves" of the dependency graph. **Skip them** in your first pass. +4. `hinputs_t.rs` is partially stubbed and uses fully-qualified paths (`crate::typing::names::names::IdT`) rather than `use` statements — leave it alone. + +## What "done" looks like + +After your work: + +1. Running `cargo check --lib` from `FrontendRust/` produces **zero** `E0425 "cannot find type"` errors for standard typing types (IdT, KindT, CoordT, INameT, ITemplataT, etc.). +2. Other error classes (duplicate `fn equals`/`hash_code`, mismatched types, missing trait impls) are **unchanged** — you haven't fixed those and you haven't made them worse. +3.

Threaded as the first parameter on every method whose Scala body intern-allocates (look for `interner.intern(` / `arena.alloc(` / `new FooT(...)` patterns in the body).

Options: +- `enum-with-arena-refs` — `pub enum Foo<'s,'t> { Variant1(&'t Variant1Payload<'s,'t>), … }`. Each variant holds an arena-allocated payload.

When yes, every struct that becomes a payload of an interned enum variant carries `pub _must_intern: MustIntern` as a private-module-only field. The agent emits the seal on every struct that the **interned-type classifier** flags — see below. + +--- + +## Cross-pass conventions (apply everywhere) + +### Abstract-def dispatcher +When a `sealed trait` declares abstract `def`s, the agent emits one dispatcher fn per abstract def on the enum's impl block: + +```rust +/* Guardian: disable-all */ +pub fn method(&self, /* args */) -> /* return */ { + match self { + // Per-variant panic arms; filled in as test paths hit them. + _ => panic!("Unimplemented: FooX::method dispatch"), + } +} +``` + +The `/* Guardian: disable-all */` annotation is mandatory — dispatchers have no 1:1 Scala counterpart (Scala's virtual call is the counterpart, realized differently in Rust). Without it, NNDX fires and TL has to add it manually. + +### `equals` / `hashCode` / `unapply` policy +- `override def equals` → realized via `impl PartialEq for FooX`, not a `pub fn eq`. The agent emits a marker stub: + ```rust + // mig: fn eq (realized-by-impl PartialEq) + // (Realized by `impl PartialEq for FooX` below.) + ``` +- `override def hashCode` → realized via `impl Hash for FooX`. Same marker shape. +- `def unapply` → realized via `TryFrom` / pattern-match. Marker: `// mig: fn unapply (realized-by-TryFrom)`. + +### `case object` / companion `object` +- `case object Foo` (Scala unit variant of a sealed trait) → unit variant on the Rust enum: `Foo(())`. Not a separate struct. +- `object Foo` (companion object with static defs) → associated `fn`s on the corresponding `impl Foo` (or `impl FooX` after suffix application). Free fns at module scope are wrong. +- `object Foo` (pure namespace, no companion class) → module-level `pub fn`s in a submodule named `foo`. Rare. + +### Val/Ref dual-enum pairs (IDEPFL) +Interned-enum families that need a transient `*ValX` companion enum + per-variant `*ValX` payloads.

The Rust version uses **arena allocation** (`bumpalo::Bump`) for output AST nodes — structs like `StructS`, `FunctionS`, `StructA`, `FunctionA` are allocated into bump arenas, and their fields hold references (`&'s [T]`) into those arenas rather than owning heap-allocated `Vec`s. + +We're partway through converting `Vec` fields to arena-allocated slices (`&'s [T]`), and this works well — build a Vec, then call `arena.alloc_slice_fill_iter(vec.into_iter())` to get a `&'s [T]`. + +The remaining problem is **HashMap fields**. Many arena-allocated structs contain `HashMap, ITemplataType>` fields (mapping type-variable runes to their inferred types). These HashMaps have their backing storage on the heap via malloc, which defeats the purpose of arena allocation. + +## Requirements + +We need a map data structure that satisfies **both** of these properties: + +1. **Arena-allocated backing storage**: The map's internal memory (buckets, entries, etc.) must be allocated from a `bumpalo::Bump` arena, not from the global heap allocator. This is so all memory for a compilation pass can be freed in one shot by dropping the arena. + +2. **Deterministic iteration order**: Iterating the map (via `.iter()`, `.keys()`, `.values()`, `.into_iter()`) must produce entries in a deterministic order — either insertion order or sorted order. The iteration order must be the same across runs given the same inputs, regardless of platform, pointer values, or hash seed. + +## Why Both Matter + +- **Arena allocation matters** because the compiler processes many compilation units, and arena-based bulk deallocation is faster and simpler than tracking individual allocations. Structs allocated in the arena shouldn't point to heap-allocated collections that outlive them or fragment memory. + +- **Deterministic iteration matters** because the Scala original iterates over maps in several places (filtering rune-to-type maps, splitting header vs member runes, flattening package contents). While most of these operations produce Maps or Sets where iteration order doesn't affect correctness, we want to guarantee determinism across the entire compiler to avoid hard-to-debug nondeterministic compilation failures. We *hate* nondeterminism. + +## What Exists Today + +| Crate | Arena support | Deterministic iteration | Notes | +|-------|-------------|------------------------|-------| +| `std::collections::HashMap` | No | No | Rust's stdlib HashMap (hashbrown internally) | +| `hashbrown::HashMap` | Yes (allocator-api2 + bumpalo) | No | SwissTable, supports custom allocators on stable Rust | +| `indexmap::IndexMap` | No | Yes (insertion order) | No custom allocator parameter | +| `std::collections::BTreeMap` | No | Yes (sorted order) | No custom allocator parameter | +| Sorted `&'s [(K,V)]` slice | Yes (trivially) | Yes (sorted) | O(log n) lookup via binary search; immutable after construction | + +None of the existing options satisfy both requirements simultaneously. + +## Usage Pattern + +The maps in question are built during a compiler pass and then stored in arena-allocated AST structs. The typical lifecycle is: + +``` +1. Create an empty map +2. Insert entries incrementally (10-50 entries typically) +3. Sometimes merge two maps (e.g., header + member runes) +4. Store the map in an arena-allocated struct +5. Read from the map via .get() and .contains_key() during later phases +6. Occasionally iterate the map (e.g., .filter(), .iter()) +7. Never mutate the map after storing it in the struct +``` + +The key type (`IRuneS<'a>`) implements `Hash + Eq + Ord + Clone` and is a small enum (tagged pointer, ~16 bytes). The value type (`ITemplataType`) also implements `Hash + Eq + Clone`. + +## Possible Approaches to Investigate + +### A. Arena-backed IndexMap +Build an IndexMap-like structure (hash table + insertion-order entry vector) where both the hash buckets and the entry storage are allocated from a `bumpalo::Bump`. Could be implemented as a wrapper around hashbrown's `RawTable` (which supports custom allocators) with an arena-allocated entry vector for ordering. + +### B. Sorted arena slices +Build the map as a `Vec<(K, V)>` during construction, then sort by key and allocate into the arena as `&'s [(K, V)]`. Lookup via binary search (`O(log n)`). Deterministic (sorted order). Very simple. Downside: O(log n) lookup instead of O(1), and immutable after construction (but our maps are never mutated after storing). + +### C. Two-phase approach +During construction (mutable phase), use a regular `IndexMap` on the heap. When storing into the arena-allocated struct, convert to a sorted `&'s [(K, V)]` slice. This gives O(1) insertion during construction and O(log n) lookup during reads, with full arena allocation for the stored form. + +### D. Patch indexmap to support allocators +IndexMap internally uses hashbrown. If indexmap exposed the allocator parameter from hashbrown, it would work with bumpalo directly. This would require upstream changes or a fork. + +### E. Accept the tradeoff +Use `indexmap::IndexMap` (deterministic, heap-allocated) and accept that these particular fields use heap allocation. The maps are small (10-50 entries) and the heap cost is minimal compared to the large arena-allocated AST nodes they live in. + +## Constraints + +- Must work on **stable Rust** (no nightly-only features) +- Maps are small (10-50 entries typically, never more than ~200) +- Keys are cheap to compare and hash +- Maps are **write-once, read-many** — never mutated after construction +- The solution will be used in ~20 struct definitions across the compiler frontend diff --git a/FrontendRust/docs/reasoning/check-scala-comments-hook.md b/FrontendRust/docs/reasoning/check-scala-comments-hook.md new file mode 100644 index 000000000..df7b79a94 --- /dev/null +++ b/FrontendRust/docs/reasoning/check-scala-comments-hook.md @@ -0,0 +1,21 @@ +# Check Scala Comments Hook — Reasoning + +## PreToolUse (not PostToolUse) + +Checks file state before each edit.

The target struct/interface was typed by a *different* top-level denizen. These lookups are real cross-denizen reads and force a tier of long-lived data. +- **Function-call memoization is narrower than it looks.** `getOrEvaluateFunctionForHeader` appears to cross denizens but actually serves as a header cache. Only lambdas (intra-containing-function) hit the templated-banner path. For non-lambda calls, declared-return functions have headers computable from templates + scout `'s` data alone. *Only inferred-return functions would need cross-denizen body typing* — and only lambdas can have inferred returns, and lambdas can't be called cross-denizen (lambda `IdT`s bake in the containing function; `LambdaCallFunctionNameT` explicitly returns `None` from imprecise-name lookup). Category 2 collapses entirely. +- **Env escape classification (per-variant, audited):** + - Escape to outputs tier (skeleton): `PackageEnvironmentT`, `CitizenEnvironmentT`, `BuildingFunctionEnvironmentWithClosuredsT`. Hold declaration-level data that other denizens must read during their typing (for method resolution, generic-bound reuse, override resolution in `EdgeCompiler`). + - Stay in scratchpad (working): `NodeEnvironmentT`, `GeneralEnvironmentT`, `ExportEnvironmentT`, `ExternEnvironmentT`, `FunctionEnvironmentT`, `BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT`. Only read during their own top-level denizen's compilation. +- **Heavy-templata escape classification:** + - Escape: `FunctionTemplataT` (stored in `FunctionHeaderT.maybeOriginFunctionTemplata` → HinputsT) and `ExternFunctionTemplataT` (held by persistent envs). + - Stay: `StructDefinitionTemplataT`, `InterfaceDefinitionTemplataT`, `ImplDefinitionTemplataT`. + - `FunctionTemplataT` escape is refactorable: no consumer actually reads `outer_env` — all readers access `function.range` / `.params` / `.name` which live in `'s`. Replace the field with `maybeOriginFunctionA: Option<&'s FunctionA>` and `FunctionTemplataT` moves to scratchpad cleanly. +- **Pointer-equality assumptions.** `IdT::Hash` / `Eq` use `std::ptr::eq` on `init_steps` and `package_coord`. Two denizens constructing structurally-equal `IdT`s would fail cross-denizen HashMap lookups unless both go through a shared interner. This forces a choice on interning strategy (see below). + +### `bumpalo` does not run destructors + +`bumpalo::Bump::alloc(&self, val: T) -> &mut T` frees memory on arena drop but does not invoke `T::drop`.

Sub-decision during the refactor; not a blocker either way. + +### Typing order / worklist semantics + +Scala's typing pass runs in three phases (confirmed by audit of `Compiler.scala`): + +1. **Indexing phase.** All top-level structs and interfaces are declared; outer envs created. Allocates into `'out`. +2. **Compiling phase.** Struct/interface bodies fully compiled (members resolved, inner envs created). Method headers deferred onto `CompilerOutputs.deferredFunctionCompiles`. Struct definitions land in `'out`. +3. **Deferred worklist phase.** `CompilerOutputs` holds two queues — `deferredFunctionCompiles` (function headers) and `deferredFunctionBodyCompiles` (bodies). A nested loop drains them. Each worklist item represents compiling one top-level denizen's function (or one generic instantiation's body). + +**Each worklist item gets its own `'scratch` arena.** When the item returns, its scratchpad drops. Deferred work the item enqueued (new bodies, new instantiations) is processed as separate worklist items with their own fresh scratchpads. + +Nested compilation *within* one worklist item (struct instantiation triggered by body typing, lambda compilation within the same top-level function) shares that item's single scratchpad. Lambdas don't need their own scratchpad — they're allocated into the containing top-level function's. + +### Interning strategy + +Cross-denizen lookups via HashMap keys (`lookupStruct(id)` etc.) need `IdT` to hash/equal consistently across denizens. Two options: + +**Option A (recommended):** Single globally-scoped `TypingInterner` for the whole pass. `IdT`, concrete names, interned types all go through one interner with pointer-identity-implies-structural-equality as its invariant. Ptr-eq `Hash`/`Eq` works everywhere. Allows two-tier arena for envs/templatas while keeping the type/name identity model simple. This matches Slab 4's interner implementation, so no long-term shift is required. + +**Option B:** Per-denizen interner. Requires switching `IdT`, heavy-templata, and container-wrapper `Hash`/`Eq` from `std::ptr::eq` to structural. Enables fully-independent per-denizen arenas for interned types, but costs a refactor of ~10 `Hash`/`Eq` impls and adds a structural-hash cost to every HashMap operation. Not worth the effort unless parallel per-denizen typing becomes a goal (see "What this doesn't give"). + +Long-term target uses **Option A**. Per-denizen scratchpads bound the high-churn data (envs, `NodeEnvironmentT` mutation) without needing per-denizen interning of stable types. + +--- + +## Required refactors to reach the target + +1. **`FunctionHeaderT.maybeOriginFunctionTemplata` → `maybeOriginFunctionA: Option<&'s FunctionA<'s>>`.** Audit confirmed no consumer touches `outer_env`; all readers (`EdgeCompiler`, `CompilerErrorHumanizer`, `FunctionBannerT.equals`) access only `FunctionA` fields. Narrow refactor (~5 call sites). Unblocks `FunctionTemplataT` for scratchpad. + +2. **Delete `envByFunctionSignature`** in `CompilerOutputs`. Dead code per audit — the only accessor is commented out. + +3. **Implement `TypingInterner` bodies globally.** `intern_id` / `intern_struct_tt` / etc. — the shape is already right in `typing_interner.rs`, the bodies are `panic!()` placeholders that need bump-alloc + hashbrown wiring. Part of Slab 4 anyway. + +4. **Keep `BuildingFunctionEnvironmentWithClosuredsT` in `'out`.** `EdgeCompiler.lookForOverride` uses this env as a live symbol table — it's passed as parent to `GeneralEnvironmentT.childOf` and various resolvers do implicit lookups through it. Refactoring to a small side-struct is harder than it first looks. Accept that this one BuildingEnv lives in outputs alongside the skeleton envs. + +--- + +## Migration path: one post-Slab-8 slab + +Scope: + +1. Stand up the `'scratch` arena type + side table infrastructure parallel to existing `'t` arena. `Compiler` gets a new `current_denizen_scratchpad: Option<&'scratch Bump>` field + `env_table: Vec<&'scratch IEnvironmentT>`. +2. Split the storage target: the existing `TypingInterner<'t>` becomes `TypingInterner<'out>` for everything that escapes, unchanged in shape. Scratchpad-class types get scratchpad-arena alloc methods. +3. Flip scratchpad-class types to allocate in `'scratch`. Every env field that was `&'t` becomes `&'scratch` or `EnvIdx`; each choice documented. +4. Apply refactor #1 (`maybeOriginFunctionA`) to sever `FunctionTemplataT` from its current `'t` home. +5. Apply refactor #2 (delete dead code). +6. Wire the worklist-item loop to push/pop a scratchpad per item: create arena, compile, drop arena, move to next item. +7. Optional follow-up: move scratchpad envs off the arena into a drop-honoring container (`typed-arena` or `Vec>`) if `HashMap` in `TemplatasStoreT` is desired. + +Each step is independently verifiable. Tests should stay green throughout if the commits are sequenced right. + +--- + +## What this gains + +- **Per-denizen memory bound.** Peak memory during function body typing bounded by the function's working set + skeleton envs, not the whole codebase. +- **Clearer Scala parity.** Each worklist item is self-contained; Scala's implicit per-compile state maps onto a literal per-compile arena. +- **Clean `bumpalo`-compatible cleanup.** Scratchpad drops cleanly; outputs arena drops at pass end. No `Rc` gymnastics. +- **`HashMap`-in-`TemplatasStoreT`** if we go the extra mile of pulling scratchpad envs off the arena into a drop-honoring container. Lookup cost drops from O(n) to O(1) for the scratchpad envs that typically see the most lookups. + +## What this doesn't give + +- **Parallel per-denizen typing.** Not impossible but requires switching `Rc` → `Arc`, making the outputs interner `Sync`, and handling `CompilerOutputs`'s cross-denizen HashMap-based queries (`lookupStruct` etc.) with shared mutable state. Deferred past this refactor. +- **Early drop of in-progress envs.** Scratchpad drops at worklist-item boundary; we don't selectively drop unused envs mid-item. Would need reachability tracking we don't have. Acceptable for batch typing. +- **Lifetime-param reduction.** Envs still hold `&'s FunctionA`, `IdT<'s,'out>`, etc. Types carry `<'s, 'out, 'scratch>` in the long-term shape — one more lifetime parameter than today's `<'s, 't>`. Tolerable but a visible cost at every signature. + +## Why not `Rc` + side-table (the earlier intermediate proposal)? + +An intermediate design considered storing all envs in `Vec>` on `Compiler`, with arena structs holding `EnvIdx`. The per-denizen design strictly supersedes it because: + +- Rc+side-table treated all envs as one tier. It didn't handle the cross-denizen skeleton-vs-working split that the audit revealed. Some envs genuinely need to live in the global outputs tier; `Rc` everywhere doesn't capture that. +- Per-denizen scratchpad has cleaner cleanup (drop a bump, done) than `Rc` refcount cascades. +- `Rc` has real per-access cost (refcount, indirect pointer); `EnvIdx` has a simple array lookup; `&'scratch` has zero overhead. Per-denizen design uses `&'scratch` for most env access and reserves `EnvIdx` for the arena-struct→env crossing. +- Per-denizen interning / deduplication of scratchpad data fits naturally; with `Rc`, there's no natural boundary for scratchpad-only vs shared. + +The `EnvIdx` side-table concept survives into the per-denizen design — it's used for the arena-struct-holding-env-reference case. But the broader framing is different. + +--- + +## Further future direction: LSP support + +The per-denizen arena design is step 1 on a longer trajectory toward supporting a language server (long-running process, incremental recompilation on edit, hover/goto-def responsiveness). This section captures the direction; concrete design is deferred past the per-denizen refactor. + +### Why per-denizen arenas are load-bearing for LSP + +Each top-level denizen's `'out` slab and `'scratch` arena form a natural invalidation unit. Source change to denizen A → drop A's slabs → recompile A. Other denizens' outputs stay valid unless A's public surface changed and cascaded. Without per-denizen arenas, the whole typing pass re-runs on every edit, which doesn't scale past small projects. + +### Remaining pieces beyond per-denizen arenas + +1. **`DefId`-indexed cross-denizen references.** Per-denizen `'out` slabs drop independently. Rust's lifetime system can't express "A holds `&'out_B FunctionHeaderT` and `'out_B` may drop without taking `'out_A` with it." Cross-denizen refs become `(DenizenId, u32)` indices resolved via a top-level `CompilerState`. Lookup returns `&'slab T` for temporary borrow, never stored. This is rustc's `DefId` / `TyCtxt` architecture. + +2. **Shatter `GlobalEnvironment` into DefId-keyed registries.** Today's single `GlobalEnvironmentT` struct becomes a set of sparse tables on `CompilerState` — `HashMap`, `HashMap`, etc. Each entry is replaceable independently. Per-package `'out` slabs drop with their entries. The "GlobalEnvironment" concept persists conceptually but isn't a struct anymore. + +3. **Split interner into local + global with single-writer cleanup.** See below — this has enough shape worth detailing. + +4. **Periodic full global-interner rebuild.** The global interner grows monotonically within an LSP session. Rather than per-entry refcounting, periodic rebuild: walk live denizens, construct a fresh global interner holding only reachable entries, atomic-swap. Can run as background work while the current interner serves ongoing compiles. Trigger mechanics (memory threshold, explicit signal, etc.) and swap protocol are deferred to a future designer. + +### Interner design: local + global with cleanup promotion + +**Model:** + +- **Global interner** persists across compiles. Indexed by content; entries are canonical across the whole session. +- **Per-denizen local interner** is transient — lives for one compile, drops when the denizen compile ends. + +**Lookup order during compilation:** + +1. When code calls `intern_(val)`, the local interner checks its own map first. +2. On local miss, fall through to the global interner (lookup only — no write). +3. On global miss, intern into local. The value is local-only until cleanup. + +**Cleanup (promotion) at denizen compile end:** + +A copy-walk over the denizen's output artifacts (FunctionHeaderT, StructDefinitionT, etc. — anything escaping into HinputsT): + +1. Deep-walk outputs, recursively visiting every field. +2. For each encountered interned value: look up in global. On miss, intern into global now. On hit, use the existing global entry. +3. Build fresh output artifacts in a new arena slab, with all interior pointers rooted in global-interned entries. +4. Drop the denizen's local arena + local interner. Everything that wasn't externally-visible dies with it. + +This is the **only** path by which values enter the global interner — cleanup is the single writer. Simplifies reasoning: during compilation, global is read-only; between compilations, cleanup writes. Fits naturally with single-threaded execution today; adapts cleanly to parallel compilation later (serialize cleanups, parallelize compiles). + +**Externally-visible criterion:** transitively reachable from the denizen's output artifacts. Anything the copy-walk touches gets promoted; anything it doesn't gets dropped with the local arena. No explicit tagging needed — reachability defines the set. + +### LSP result-return timing + +Two kinds of results from a denizen compile; they return at different times: + +- **Diagnostics (errors, warnings)** return *before* cleanup. They reference source locations + semantic descriptions, not compiler types — no promotion needed. Time-critical for editor squigglies. +- **Typed results** (AST for hover, type info for goto-def, HinputsT fragments) return *after* cleanup. LSP consumers hold them across edits, so they need to live in global-interned form to survive the denizen's local arena drop. + +### Identity strategy: fully-qualified name + +Each top-level denizen has a stable `DefId` = its fully-qualified name (package path + item name). Stable across compiles, renaming changes identity (acceptable — a rename is semantically a delete + create). Source-location-based IDs were considered and rejected as too fragile (reordering code shouldn't change identity). UUID-assigned-on-first-compile was considered too complex. + +### Denizen unit: top-level only + +One `'out` slab and one `'scratch` arena per **top-level denizen** — top-level function, struct, interface, or impl. Nothing smaller. Specifically: + +- Lambdas share their containing top-level function's arenas (already decided in the migration-phase design). +- **Monomorphizations do not get their own denizen status.** LSP and monomorphization are orthogonal. Typing produces generic `FunctionDefinitionT` at top-level-function granularity; monomorphization happens post-typing in the instantiator and is not part of the LSP incrementality story. Whether and how the instantiator participates in LSP is a separate concern, out of scope here. + +### Deferred decisions + +The following are left to the future designer who actually implements LSP mode: + +- Global-interner purge trigger and background rebuild protocol. +- Atomic swap mechanics between old and new global interners. +- Parallelism. Per-denizen arenas and single-writer cleanup naturally permit parallel compilation with serialized cleanup, but sequential single-threaded is the current and near-term target. Parallelism is a future goal, not a design constraint now. +- Instantiator incrementality (if monomorphization is made incremental, it's a separate layer over LSP-ready typing). + +--- + +## See also + +- `docs/architecture/typing-pass-design-v3.md` Part 1 — current (migration-phase) typing-pass arena architecture. +- `FrontendRust/docs/migration/handoff-slab-4.md` — Slab 4 handoff implementing the migration-phase arena design. +- `FrontendRust/docs/reasoning/arena-deterministic-maps.md` — why arena-backed maps don't exist for us; part of why envs-in-arena forces slice-based `TemplatasStoreT`. +- `FrontendRust/docs/reasoning/idt-typed-view-alternatives.md` — sister doc recording a similar "chosen for migration, alternatives deferred post-migration" decision for `IdT`. +- `Luz/shields/ArenaAllocatedStructsShouldNotContainMallocdCollections-AASSNCMCX.md` — the shield forcing slice-based `TemplatasStoreT` today; lifts when envs move off arena. +- `FrontendRust/docs/shields/ArenaTypesDontClone-ATDCX.md` — the shield that already carves out "working state (envs, solver types) may have `Clone`-without-`Copy`," anticipating the move to heap-storage working state. diff --git a/FrontendRust/docs/reasoning/idt-typed-view-alternatives.md b/FrontendRust/docs/reasoning/idt-typed-view-alternatives.md new file mode 100644 index 000000000..a58b3daeb --- /dev/null +++ b/FrontendRust/docs/reasoning/idt-typed-view-alternatives.md @@ -0,0 +1,74 @@ +# Reasoning: IdT Typed-View Alternatives + +`IdT<'s, 't>` represents a typing-pass name path: `myapp::foo::bar::someFunc`.

Generic `IdT<'s, 't, T: Copy>` with widest-form interning and custom Eq + +The original Slab 2 attempt (committed as `1811a12f..8359c0bf`). `IdT` is generic in its leaf-name type `T`. Interned; the interner uses one HashMap keyed by the widest form (`IdValT<..., INameT>`), and each specialization is served by an unsafe type-cast of the widened arena storage. Custom `PartialEq`/`Eq`/`Hash` on `IdT` because identity is per-field (`ptr::eq` on `package_coord` + `init_steps` slice, structural on `local_name`). + +- **Pros:** Type-level assertion at call sites (can't accidentally pass a function-id where a struct-id is required). `widen`/`try_narrow` available as methods. +- **Cons:** Sharing arena storage across T-specializations requires layout invariance (`IdT<..., IFunctionNameT>` and `IdT<..., INameT>` must have the same byte layout at runtime). Rust doesn't guarantee this without `#[repr(u8)]` discriminant alignment across every name sub-enum. Without that guarantee, `widen`/`try_narrow` have to actually re-intern (HashMap round-trip, no new allocation but not free either). Call sites carry the T parameter noise in every signature. Also, when working with owned `IdT` values (not `&'t`), `widen(self)` constructs a new struct with a changed local_name variant — which means the interner has to dedup that new form back to the existing canonical storage. + +Expected revisit: if post-migration profiling shows the monomorphic design loses to the type-level contract for catching bugs, AND we're willing to pay the layout-invariance + re-intern costs (or switch to Alternative 2). + +### 2. Unsafe transmute between typed `&'t IdT<..., T>` views + +Keep the generic `IdT<'s, 't, T: Copy>` but use `#[repr(u8)]` (or equivalent) to pin the discriminant byte layout across every name sub-enum so that `IdT<..., IFunctionNameT>` and `IdT<..., INameT>` have byte-identical in-memory representations. Then `widen` and `try_narrow` become `unsafe { transmute(&'t IdT<..., T1>, &'t IdT<..., T2>) }` — zero-cost typed views over the same arena storage. + +- **Pros:** Typed widen/narrow is a no-op at runtime. Single arena allocation per logical IdT. +- **Cons:** Requires every name sub-enum to coordinate discriminant values manually (`IFunctionNameT::Function = 0`, `INameT::Function = 0`, etc.) — one mismatch and the compiler silently corrupts data. No ergonomic way to enforce this across 22 sub-enums. Unsafe boundary is easy to violate accidentally when someone adds a variant. Bug surface is large and debugging is awful. + +Expected revisit: only if Alternative 3 proves ergonomically unacceptable AND profiling shows the HashMap re-intern cost of Alternative 1 is unacceptable. + +### 3. `RawIdT<'s, 't>` canonical + pointer-wrapper typed view + +Split the type: `RawIdT<'s, 't>` is the monomorphic canonical form (interned in the arena). A separate `IdT<'s, 't, T: Copy>` is a thin stack-only wrapper holding `&'t RawIdT<'s, 't>` and a `PhantomData` (or a cached narrow `local_name: T` for zero-access-cost). + +```rust +pub struct RawIdT<'s, 't> { /* always widest */ } +pub struct IdT<'s, 't, T: Copy> { raw: &'t RawIdT<'s, 't>, _phantom: PhantomData } +``` + +- **Pros:** One HashMap, one Val type, one intern method. No layout coordination across sub-enums. Typed view is pointer-sized (8 bytes, Copy). `widen`/`try_narrow` are pure stack operations (no HashMap probe, no allocation). Compile-time type-safety preserved. +- **Cons:** Ergonomic tax — `id.local_name` becomes `id.local_name()` (method with a one-arm match that the optimizer may or may not elide). Construction ceremony: `IdT::try_new(raw)?` instead of implicit coercion. Equality semantics: two typed views compare via their inner `raw` ptr; fine as long as `RawIdT` is always interned, but a footgun if someone stack-constructs a `RawIdT`. If we add a cached inline `local_name: T` field to the wrapper to avoid per-access match cost, the wrapper grows to 16–24 bytes (still Copy, still cheap to pass, but not pointer-sized). + +Expected revisit: this is the most likely post-migration winner. The ergonomic tax is small compared to the design clarity win. Cached-inline variant is probably what ships. + +### 4. Type erasure at every call site (status quo, monomorphic) + +What we have today. Always the widest form. No generic T. Callers pattern-match on `local_name` at the point they need narrowing. + +- **Pros:** Simplest possible design. Zero ambiguity about interner semantics. Closest to Scala-at-runtime (phantom T is erased at JVM runtime anyway — the `+T` is purely compile-time). Easy to reason about. +- **Cons:** Loses compile-time type assertions at call sites. A function that takes `id: IdT<'s, 't>` can't express "I require an id whose local_name is a FunctionName" via the type system — it has to pattern-match at runtime and panic/err if wrong. This is where Rust idiomatically does better than Scala, and we're giving that up. + +Accepted during migration. Revisit post-migration. + +## Migration parity note + +Scala's `IdT[+T <: INameT]` with specialized narrow-name types (`IdT[IFunctionNameT]`, `IdT[IStructNameT]`, etc.) imposes no runtime cost in Scala because of JVM type erasure — `+T` is compile-time-only.

The call sites don't change syntax — `stack_frame.clone()` still works, but now it clones the `Rc` (refcount bump) instead of deep-copying the entire struct chain. + +The only call sites that need actual changes are ones that access the inner data through the `Rc`: +- `stack_frame.parent_env.declared_runes` stays the same (auto-deref through `Rc`) +- `stack_frame.parent_env.clone()` becomes cheap (cloning the `Rc`) + +### Step 4: Change `plus()` + +`StackFrame::plus()` currently clones all fields to return a new `StackFrame` with updated locals.

Currently: +```rust +let maybe_parent = parent_stack_frame.clone().map(Box::new); +``` + +With Rc: +```rust +let maybe_parent = parent_stack_frame.map(Rc::new); +// or if parent_stack_frame is already Rc: +let maybe_parent = parent_stack_frame.clone(); // if it's Option> +``` + +The exact change depends on whether `new_block` receives the parent as an owned `StackFrame` or `Rc`. Since `new_block` is typically called from `scout_block` which receives the stack frame and wants to keep using it, the cleanest approach is: +- `scout_block` receives `stack_frame: StackFrame<'s>` (owned) +- Wraps it in `Rc` at the start: `let stack_frame = Rc::new(stack_frame);` +- Passes `Rc::clone(&stack_frame)` to all sub-calls +- `new_block` receives `parent_stack_frame: Option>>` + +Alternatively, keep passing stack frames by value into `scout_block` and only wrap in `Rc` for child stack frames.

temp-disable: SPDMX — The Scala uses `contentsRuntimeSizedArrayTT(mutability, _, _)` which is a Scala extractor equivalent to `rsa.name.local_name → RuntimeSizedArrayNameT { arr, .. } →

The Rust data model stores mutability on `RawArrayNameT` (accessed via `name.local_name → INameT::RuntimeSizedArray → .arr.mutability`), so an extra nested match arm is structurally required for exhaustiveness.

The transient Val +// replaces those with `&'tmp [...]` slices borrowed from a stack-local Vec +// so lookup can hash/compare without allocating.

Conversion between levels uses `From` impls or explicit methods. + +**Scala hierarchy:** +```scala +sealed trait INameS extends IInterning + sealed trait IVarNameS extends INameS + case class CodeVarNameS(...) extends IVarNameS + case class ClosureParamNameS(...) extends IVarNameS + sealed trait IFunctionDeclarationNameS extends INameS + case class FunctionNameS(...) extends IFunctionDeclarationNameS + case class LambdaDeclarationNameS(...) extends IFunctionDeclarationNameS + case class LetNameS(...) extends INameS +``` + +**Rust translation:** +```rust +// Top-level enum wraps sub-enums as variants +pub enum INameS<'a> { + VarName(&'a IVarNameS<'a>), + FunctionDeclaration(&'a IFunctionDeclarationNameS<'a>), + LetName(&'a LetNameS<'a>), + // ... +} + +// Sub-enum is its own independent enum +pub enum IVarNameS<'a> { + CodeVarName(&'a CodeVarNameS<'a>), + ClosureParamName(&'a ClosureParamNameS<'a>), + // ... +} + +// Sub-enum is its own independent enum +pub enum IFunctionDeclarationNameS<'a> { + FunctionName(&'a FunctionNameS<'a>), + LambdaDeclarationName(&'a LambdaDeclarationNameS<'a>), + // ... +} + +// Conversions between levels +impl<'a> From<&TopLevelStructDeclarationNameS<'a>> for TopLevelCitizenDeclarationNameS<'a> { ... } +impl<'a> From<&TopLevelInterfaceDeclarationNameS<'a>> for TopLevelCitizenDeclarationNameS<'a> { ... } +``` + +The parent enum wraps each sub-enum in one of its own variants (e.g. `INameS::VarName(&'a IVarNameS<'a>)`). Code that needs the broader type uses the parent enum; code that knows the specific sub-type works with the narrower enum directly. `From` impls let you go from narrow → wide. + +### 1.4 Case Objects → Unit Structs + +Scala `case object Foo extends Bar` becomes `pub struct Foo;` (a zero-sized type), wrapped in an enum variant where needed. + +**Scala:** +```scala +case object PureS extends IFunctionAttributeS +case object SealedS extends ICitizenAttributeS +``` + +**Rust:** +```rust +pub struct PureS; +pub struct SealedS; + +pub enum IFunctionAttributeS<'a> { + Pure(PureS), + // ... +} +``` + +--- + +## Part 2: Memory Management + +### 2.1 GC References → Arena Allocation With Lifetime Parameters + +Scala objects lived on the JVM's garbage-collected heap. In Rust, we use `bumpalo::Bump` arenas with explicit lifetime parameters. Every type that was a plain value in Scala gains lifetime parameters in Rust. + +The codebase uses **four arena lifetimes** (documented in detail in `.claude/rules/postparser/early-lifetimes.mdc`): + +- **`'a`** — Interner arena (longest-lived): all interned strings, names, types, coordinates +- **`'p`** — Parser AST arena: input nodes from the parser +- **`'s`** — Scout (postparser output) arena: transformed output nodes +- **`'ctx`** — Context/infrastructure borrows: `&'ctx Interner<'a>`, `&'ctx Keywords<'a>` + +Functions that produce AST nodes call `arena.alloc(...)` and return `&'s T` instead of owned `T`. This means return types change from owned values in Scala to arena references in Rust: + +**Scala:** `def translateStruct(...): StructA` +**Rust:** `fn translate_struct(...) -> &'s StructA<'a, 's>` + +### 2.2 Arena-Allocated Structs Must Not Contain Malloc'd Collections (XAASSNCMC) + +Structs stored via `bumpalo::Bump::alloc` (as `&'s T`) must use arena slices (`&'s [T]`) instead of `Vec` for their collection fields. + +**Why:** Bumpalo does not run destructors. A `Vec` inside an arena-allocated struct will leak its heap allocation when the arena is dropped, because `Vec::drop` never runs. + +**Scala:** +```scala +case class StructA( + genericParameters: Vector[GenericParameterS], + members: Vector[IStructMemberS]) +``` + +**Rust:** +```rust +pub struct StructA<'a, 's> { + pub generic_parameters: &'s [&'s GenericParameterS<'a, 's>], + pub members: &'s [IStructMemberS<'a>], +} +``` + +Use `alloc_slice_from_vec()` from `utils/arena_utils.rs` to convert a `Vec` into `&'s [T]` before storing it in an arena-allocated struct. + +### 2.3 Interning: `HashMap[T, T]` → Dual-Enum IDEPFL Pattern (XIID) + +Scala's `Interner` used `HashMap[T, T]` with JVM reference equality (`eq`) to canonicalize case classes. Rust replaces this with arena-backed interning using two parallel enums per type hierarchy: + +- A **reference enum** (canonical, holds `&'a` pointers) — used everywhere in the program +- A **value enum** (owned, used as HashMap lookup keys) — used only for interner lookups + +The interning flow is: +1. Build an owned value (the Val enum variant) with all data inline +2. Look it up in `HashMap` — if found, return the existing canonical ref +3. If new: allocate the payload into the `'a` arena, wrap in the ref enum variant, store the mapping + +```rust +// Reference enum (canonical): +pub enum IRuneS<'a> { + CodeRune(&'a CodeRuneS<'a>), // holds &'a to arena + ImplicitRune(&'a ImplicitRuneS), +} + +// Value enum (for HashMap lookup): +pub enum IRuneValS<'a> { + CodeRune(CodeRuneS<'a>), // holds owned value + ImplicitRune(ImplicitRuneS), +} +``` + +Identity comparison uses `ptr_eq()` / `canonical_ptr()` instead of JVM `eq`. Interned values must be interned immediately after creation — a bare value should only exist very temporarily before being handed to the `Interner`. + +For nested interned types, a "shallow Val" struct exists where children are already-canonical references. Children must be interned first, then the parent Val is built with canonical child references. See the IDEPFL document in `.claude/rules/postparser/` for the full details. + +### 2.4 Strings: `String` → `StrI<'a>` (More Aggressive Interning) + +Scala: `case class StrI(str: String)` — GC-managed, interned via `HashMap`. +Rust: `pub struct StrI<'a>(pub &'a str)` — arena-backed interned string reference. + +Rust interns strings more aggressively than Scala did. Many places where Scala held a plain `String` now hold `StrI<'a>`. + +### 2.5 `Map[K, V]` → `HashMap` + +Scala's immutable `Map` becomes Rust's `HashMap`. Straightforward replacement. + +--- + +## Part 3: Code Organization + +### 3.1 Classes With Fields → Methods on a Shared Struct (or Free Functions With Explicit Params) + +Scala had many small classes (`FunctionScout`, `ExpressionScout`, `PatternScout`, `TemplexScout`, `RuleScout`) each storing `interner`, `keywords`, etc. as constructor fields. In Rust, these were handled two ways: + +**Strategy A — Collapse into one struct:** All the scout classes became methods on `PostParser`, which holds `interner`, `keywords`, and `arena` once. The delegate/callback patterns between them disappeared since they're all `self.method()` now. + +**Scala (separate classes with delegate):** +```scala +class FunctionScout(postParser: PostParser, interner: Interner, ...) { + val expressionScout = new ExpressionScout( + new IExpressionScoutDelegate { + override def scoutLambda(parentStackFrame, lambdaFunction0) = { + FunctionScout.this.scoutLambda(parentStackFrame, lambdaFunction0) + } + }, + templexScout, ruleScout, patternScout, interner, keywords + ) +} +``` + +**Rust (methods on one struct, no delegate needed):** +```rust +impl<'a, 'p, 'ctx, 's> PostParser<'a, 'p, 'ctx, 's> { + fn scout_function(&self, ...) { ... } + fn scout_expression(&self, ...) { + // Can call self.scout_lambda() directly — no delegate needed + self.scout_lambda(stack_frame, &lambda.function)?; + } + fn scout_lambda(&self, ...) { ... } + fn translate_pattern(&self, ...) { ... } +} +``` + +**Strategy B — Free functions with explicit params:** Where methods couldn't easily be on a struct (e.g. helper functions in `higher_typing_pass.rs`), fields like `interner` became explicit function parameters: + +```rust +// Scala: method on a class that has `interner` as a field +// private def coerceKindLookupToCoord(runeAToType, ruleBuilder, range, resultRune, name) = ... + +// Rust: free function, interner passed explicitly +fn coerce_kind_lookup_to_coord<'a>( + interner: &Interner<'a>, // was a class field in Scala + rune_a_to_type: &mut HashMap, ITemplataType>, + rule_builder: &mut Vec>, + range: RangeS<'a>, + result_rune: RuneUsage<'a>, + name: &IImpreciseNameS<'a>, +) { ... } +``` + +### 3.2 Anonymous Classes → Named Structs With Trait Impls + +Scala's `new IFoo { override def bar(...) = ... }` anonymous class pattern can't exist in Rust. These become named structs with explicit trait implementations. + +**Scala (anonymous class):** +```scala +val solveRule = new ISolveRule { + override def complexSolve(...) = { ... } +} +``` + +**Rust (named struct + trait impl):** +```rust +pub struct RuneTypeSolverDelegate { pub predicting: bool } + +impl SolverDelegate<...> for RuneTypeSolverDelegate { + fn complex_solve(&self, ...) -> ... { ... } +} +``` + +This was applied in multiple places: `IdentifiabilitySolverDelegate`, `RuneTypeSolverDelegate`, `HigherTypingRuneTypeSolverEnv` (which replaced six inline Scala anonymous classes with one named struct). + +### 3.3 Constructor-Parameter Closures → Trait Methods on Delegate + +When Scala passed lambda parameters to a class constructor, Rust moves those lambdas into trait methods on a delegate. + +**Scala:** +```scala +class Solver( + ruleToPuzzles: Rule => Vector[Vector[Rune]], + ruleToRunes: Rule => Iterable[Rune], + solveRule: ISolveRule) +``` + +**Rust:** +```rust +trait SolverDelegate { + fn rule_to_puzzles(&self, rule: &Rule) -> Vec>; + fn rule_to_runes(&self, rule: &Rule) -> Vec; + fn complex_solve(&self, ...) -> ...; +} + +struct Solver> { + delegate: D, +} +``` + +### 3.4 By-Name Parameters → `FnOnce` Generic Params + +Scala's by-name parameters (lazy evaluation blocks passed to functions) became Rust generic `F: FnOnce(...)` parameters. + +```rust +fn new_block( + &self, + env: EnvironmentS<'a>, + parent_stack_frame: Option>, + lidb: &mut LocationInDenizenBuilder, + range_s: RangeS<'a>, + context_region: IRuneS<'a>, + initial_locals: VariableDeclarations<'a>, + scout_contents: F, // was a by-name block in Scala +) -> Result<..., ICompileErrorS<'a>> +where + F: FnOnce(StackFrame<'a>, &mut LocationInDenizenBuilder) -> Result<..., ICompileErrorS<'a>>, +``` + +### 3.5 Companion Objects → `impl` Blocks or Free Functions + +Scala companion objects with factory methods, extractors (`unapply`), and utilities became either `impl` blocks with associated functions or standalone `pub(crate) fn` functions. + +--- + +## Part 4: Error Handling + +### 4.1 Exception Throwing → `Result` With `?` (XRRIF) + +Scala's `throw CompileErrorExceptionS(...)` becomes `return Err(...)` with `Result` return types and `?` propagation. Because of this, a vast number of functions in Rust have `Result` return types — this is expected and fine. Many functions that didn't return `Result` in Scala now do, because one of their indirect callees returns a `Result`. + +### 4.2 Unimplemented Code Must `panic!()` (XTUCMP) + +Every TODO or unimplemented branch gets a `panic!()` with a unique identifying message. Functions that are entirely `panic!()` stubs are fine during migration — they mark code that hasn't been translated yet and will fail loudly at runtime if accidentally reached. + +```rust +pub fn scout_loop(&self, ...) -> ... { + panic!("Unimplemented scout_loop"); +} +``` + +### 4.3 Fail Fast, Never Recover (XFFFL, XNRAF) + +Propagate errors immediately using `?`. Panic on unexpected conditions, protocol violations, and malformed input. Never silently fail, log-and-continue, use defaults, skip bad data, or gracefully degrade. + +--- + +## Part 5: Fidelity Principles + +These rules ensure the Rust code stays as close to Scala as possible, making it easier to verify correctness and complete the migration. + +### 5.1 Mirror Scala As Close As Possible (XRSMSCP) + +Keep Rust implementations mirroring Scala exactly: same functions, their positions relative to each other, their names, their logic, and where possible variable names too. `panic!()`s for unimplemented features are acceptable. + +### 5.2 Port Structure Exactly (XPSE) + +Port the Scala structure as-is, with panics for unimplemented parts. Don't restructure, simplify, or "improve" during migration. + +### 5.3 No Novel Code During Migrations (XNNCDM, XNND) + +All Rust code must correspond to Scala code. Novel implementations are forbidden. No new functions, structs, traits, enums, impl blocks, type aliases, or consts/statics that don't exist in the corresponding Scala. Use `panic!()` stubs instead of novel implementations. + +The exceptions to this are infrastructure required by Rust's ownership model (arenas, lifetime parameters, the dual-enum interning system, `From` impls between enum levels, `canonical_ptr`/`ptr_eq` methods). + +### 5.4 No Moved Definitions (XNMD) + +Definitions must stay in their original file locations relative to the Scala comments. Moving them breaks the 1:1 spatial mapping that makes migration verification possible. + +### 5.5 Same Helper Calls (XSHCNE) + +Rust must call the same helper functions as Scala. Don't inline helpers, extract new ones, or substitute different functions. If Scala calls `foo()` then calls `bar()`, Rust should call `foo()` then `bar()`. + +### 5.6 Closer to Scala, Not Further (XCSTNF) + +Every change must move the Rust code closer to Scala's structure, not further away. If you're tempted to restructure something, resist — match Scala first, refactor later (if at all). + +### 5.7 No Valid Simplifications (XNVSE) + +Don't assume something is a "valid simplification for migration purposes." Don't assume we can make up something simpler because we're migrating piece by piece. Port the Scala code exactly. Don't take shortcuts. + +### 5.8 Don't Conveniently Change Requirements (XDCCR) + +If a test fails, never make the test expect the current bad behavior. The Scala tests all passed. The Rust tests should pass with the exact same expectations. Fix the code to match Scala semantics, don't adjust expectations. + +--- + +## Part 6: Naming and Style + +### 6.1 `camelCase` → `snake_case` (XNRD) + +Field names, method names, and local variables convert: `packageCoord` → `package_coord`, `scoutLambda` → `scout_lambda`, `maybeParent` → `maybe_parent`. Definition names must otherwise match Scala exactly (accounting for this case convention change). + +### 6.2 Suffix Variables for Stages (XSWDWMS) + +In functions handling multiple data stages (which is common — most functions transform data from one stage to the next), suffix local variables so it's clear which stage they reference: + +```rust +let header_range_s = PostParser::eval_range(file, header_range); +let range_s = PostParser::eval_range(file, range); +let ret_range_s = PostParser::eval_range(file, ret_range); +``` + +### 6.3 Rust Code Goes Above Its Scala Comment (RCSBASC) + +For every Rust definition, put it directly above the old Scala definition comment. New Rust definitions are interleaved with old Scala comments. Don't change or remove Scala comments, but you may split a comment into two so you can put Rust code between them. + +### 6.4 Migrate All Comments (XMACT) + +All Scala comments must be ported to Rust. Rust may have additional comments that Scala doesn't have, that's fine. + +### 6.5 Use `use` Imports, Not `crate::` Paths in Bodies (XUUSNNCB) + +Add `use` statements at the top for short names; avoid `crate::module::Type` inline in function bodies. + +### 6.6 Eliminate All Warnings (XEAW) + +Work is not done if there are still compiler warnings. + +### 6.7 No Expensive Clones (XNEC) + +Stop and ask the human before implementing `Clone` for a potentially large data structure. Cloning is sometimes needed in Rust when it's not in Scala, but only for value types — nothing that might ever be mutated. + +### 6.8 Keep Inline Comparisons Inline (XKICI) + +If Scala has an inline comparison/check inside a `match`/`case`, keep that check inline in the Rust pattern. Don't move it into a guard. Don't move it outside the match. + +### 6.9 `Profiler.frame` Wrappers → Dropped + +Scala wrapped hot paths in `Profiler.frame(() => { ... })`. Rust drops these entirely — there is no equivalent and they're not needed. + +### 6.10 Explicit Arguments, No Defaults (XEANODV) + +Every argument must be explicitly supplied. No optional or defaulted parameters. + +### 6.11 Never Downcast Traits (XNEDC) + +No `downcast_ref`, `downcast_mut`, or `Any` inspection. If you need a downcast, the trait is missing methods. + +--- + +## Part 7: Testing + +### 7.1 All Tests Must Pass (XATEISP) + +Every Scala test needs a corresponding Rust test. Don't assume any tests are unimportant or unnecessary. + +### 7.2 No Conditionals in Tests (XNHCIT, XNCTOBPAOP) + +Tests should be rigid with hard expectations, no if-statements. If a match is needed, one branch proceeds, all others panic. + +### 7.3 Use `expect_` Functions and `collect_` Macros (XUEFIAI, XUCMTRS) + +Instead of asserting length then indexing, use `expect_1`, `expect_2`, etc. Use `collect_only!`, `collect_where!` for recursive pattern matching across ASTs. + +### 7.4 Tests Prefer `unwrap` Over `expect` (XTPUTEFC) + +Use `.unwrap()` instead of `.expect()` in tests for brevity. + +### 7.5 Never Repeat Implementation Code in Tests (XNRICIT) + +Tests should call public APIs and assert on behavior, not duplicate implementation logic. + +### 7.6 Prefer Single Match Over Nested Matches (XPSMONM) + +Use one match with nested patterns instead of multiple nested matches. + +--- + +## Part 8: Allowed Differences + +These differences between Scala and Rust are expected and should not be flagged: + +- **Arc wrapping:** Shared values may need `Arc` (but `Arc>` is a code smell requiring human-written justification) +- **Clone:** Sometimes needed in Rust when not in Scala, but only on value types +- **Box:** Sometimes needed in Rust for recursive types +- **`Profiler.frame()`** calls are dropped +- **`StringBuilder`** → `String::new()` / `push_str()` +- **`vimpl()`** → `panic!()` +- **`vassert()`** → `assert!()` +- **`vassertSome`** → `.expect()` +- **`Accumulator`** → `Vec` +- **`Either`** → custom Rust enums +- **Unused Scala variables** → underscored in Rust +- **Multi-line vs single-line strings** in tests +- **`match` vs `assert!(matches!(...))}`** — logically equivalent checks are fine +- **Asserting length** — `assert_eq!(args.len(), 3)` vs Scala pattern `Vector(_, _, _)` are both fine + +--- + +## Appendix: Luz Principle Cross-Reference + +The strategies above incorporate the following principles from `/Volumes/V/Luz/`: + +| Code | Principle | Sections | +|------|-----------|----------| +| XSSTRE | Scala Sealed Traits to Rust Enums | 1.1 | +| XESCCD | Enums Shouldn't Contain Complex Data | 1.2 | +| XAASSNCMC | Arena Structs No Malloc'd Collections | 2.2 | +| XIID | Immediate Interning Discipline | 2.3, 2.4 | +| XRSMSCP | Rust Should Mirror Scala | 5.1 | +| XPSE | Port Structure Exactly | 5.2 | +| XNNCDM | No Novel Code During Migrations | 5.3 | +| XNND | No New Definitions | 5.3 | +| XNRD | No Renamed Definitions | 6.1 | +| XNMD | No Moved Definitions | 5.4 | +| XSHCNE | Same Helper Calls No Exceptions | 5.5 | +| XCSTNF | Closer to Scala Not Further | 5.6 | +| XNVSE | No Valid Simplifications | 5.7 | +| XDCCR | Don't Conveniently Change Requirements | 5.8 | +| XNCWSR | No Changes Without Scala Reference | 5.3 | +| XNASC | No Adding Scala Comments | 6.3 | +| XRRIF | Returning Result Is Fine | 4.1 | +| XTUCMP | TODOs Must Panic | 4.2 | +| XFFFL | Fail Fast Fail Loud | 4.3 | +| XNRAF | Never Recover Always Fail | 4.3 | +| XMACT | Migrate All Comments Too | 6.4 | +| XSWDWMS | Suffix When Dealing With Multiple Stages | 6.2 | +| XNEC | No Expensive Clones | 6.7 | +| XKICI | Keep Inline Comparisons Inline | 6.8 | +| XEANODV | Explicit Arguments No Defaults | 6.10 | +| XNEDC | Never Downcast Traits | 6.11 | +| XUUSNNCB | Use `use` for Short Names | 6.5 | +| XEAW | Eliminate All Warnings | 6.6 | +| XATEISP | All Tests Must Pass | 7.1 | +| XNHCIT | No Conditionals in Tests | 7.2 | +| XNCTOBPAOP | One Branch Proceeds Others Panic | 7.2 | +| XUEFIAI | Use expect_ Functions | 7.3 | +| XUCMTRS | Use collect_ Macros | 7.3 | +| XTPUTEFC | Tests Prefer unwrap | 7.4 | +| XNRICIT | Never Repeat Implementation in Tests | 7.5 | +| XPSMONM | Prefer Single Match Over Nested | 7.6 | +| XAIMITIP | Avoid if matches! in Tests | 7.2 | +| XPROPRC | Prefer Result Over Panic for Recoverable | 4.1 | diff --git a/FrontendRust/zen/migration_checks.md b/FrontendRust/zen/migration_checks.md deleted file mode 100644 index 878ecea4c..000000000 --- a/FrontendRust/zen/migration_checks.md +++ /dev/null @@ -1,178 +0,0 @@ - -# Rust should mirror Scala as close as possible (RSMSCP) - -Keep making sure that everything in the rust version mirrors almost exactly whats in the scala version.

The body-translation rule (translate every line literally, no simplifications) is in `migration_principles.md` DCCR + `migration-drive.md`. + +**Second priority: every Rust function must be immediately followed on the next line by a `/* ... */` comment containing its Scala equivalent.** Use the "Slicing In New Definitions" pattern below; pre-existing fns lacking an adjacent block are tech debt, not precedent. + +**TL/reviewer addition:** when handing off, quote the Scala verbatim and tell JR to mirror it; when reviewing, flag any place the Rust shape diverges from the Scala shape, even when the divergence "obviously works." A clever translation nobody can verify against the Scala is worse than a verbose one anyone can. + +**Known principled divergence: covariant generic parameters.** Scala uses covariant generic parameters (e.g. `PrototypeT[+T <: IFunctionNameT]`, `IdT[+T <: INameT]`) to thread compile-time narrowing through containers; Rust does not try to mimic this. Containers carry the wide enum (`IdT<'s, 't>` with `local_name: INameT`), and use sites narrow at runtime via `TryFrom` (`IFunctionNameT::try_from(name).unwrap()`) or the corresponding `expect_*` accessor. The `.unwrap()` / `expect()` is the documented runtime stand-in for Scala's compile-time `T <: …` bound. + +**Guardian isn't perfect — bad edits slip through.** Some Scala-divergences land without firing any shield (e.g. `resolve_struct_layer` inlined Scala's `solveForResolving` helper as three separate calls; SPDMX caught it the second time when JR mirrored the same shape into `resolve_interface_layer`). Stay vigilant on review: every diff gets eyes against Scala, even when Guardian is silent. When you spot the divergence, course-correct JR (and the prior precedent if needed) — don't let the broken pattern propagate. + +**Don't trust JR when they argue to bypass Guardian.** "The same pattern was already approved in X" is often JR pointing at a slipped-through bug as evidence the new bug is fine.

All currently panic at the first method body they exercise. + +**Latest passing test: `tests_panic_return_type` (Slab 15i).** The next ignored test in `compiler_tests.rs` order is the current driving target. Pre-15i passing tests (`simple_program_returning_an_int_explicit`, `hardcoding_negative_numbers`, `taking_an_argument_and_returning_it`, etc.) remain un-ignored as regression guards. + +--- + +## Recurring bug classes + +**Hand-rolled enumerations of "is-a-Trait" sets.** Scala's `case x : ITrait => …` matches every subtype automatically; Rust ports that hand-enumerate the variants drift the moment one is added — always use `TryFrom for NarrowEnum::is_ok()` instead (the scaffolding-generated TryFrom impls cover every variant correctly). + +**Hand-rolled `ptr::eq(self, other)` on a Polyvalue's outer `&self`.** Works while the enum is always held behind `&'t Outer` (the outer address coincides with the arena address); silently breaks the moment it's flipped to by-value — `self` becomes a stack address, two by-value copies of the same logical wrapper compare unequal, and any `HashMap`/`HashSet` keyed on them silently corrupts. Caught once in `environment.rs:60-67` after the `IEnvironmentT` by-value flip. Rule: Polyvalue enums must `#[derive(PartialEq, Eq, Hash)]` — see @PVECFPZ. + +**`'t: 'ctx` / `'s: 'ctx` are already implied by the `Compiler` struct** (via well-formedness on its `&'ctx X<'s, 't>` fields — the struct couldn't exist otherwise), so it's fine to restate them explicitly on a local `impl` `where` clause when rustc fails to propagate the implied bound through HRTB/invariance (e.g. `Box, ...) + 'ctx>` in pattern_compiler.rs's CPS chain). Never declare the reverse `'ctx: 't` — that's the bound rustc *suggests* but it's architecturally backwards (Compiler is stack/`'ctx` data and dies before `'t`). + +**Parallel Builder/Frozen APIs diverging asymmetrically from Scala.** When one Scala API (e.g. `TemplatasStore.addEntries`) is split into a Rust Builder + Frozen pair (`TemplatasStoreBuilder::add_entries` at `environment.rs:851-862` vs `TemplatasStoreT::add_entries` at `environment.rs:942-979`), both must mirror Scala's full logic including special-case branches — review them side-by-side against the single Scala source. + +**Two-channel errors collapsed into one.** When a Scala fn both `throw`s `CompileErrorExceptionT` *and* returns `Result[_, SomeLocalError]`, the Rust mirror is nested `Result, ICompileErrorT>` — outer is the exception channel (every caller `?`-propagates), inner is the business channel (callers inspect and react).

Cosmetic; documents the divergence so reviewers don't flag it. +- **`ITemplataT::tyype()` getter is unimplemented** — Scala has it on the trait; Rust needs a per-variant match returning `ITemplataType<'s>`. Surfaces in `LetExprRuneTypeSolverEnv::lookup`'s `Some(_x) => panic!()` arm.

Each becomes a per-site named struct following the `LetExprRuneTypeSolverEnv` pattern when its containing function gets migrated.

Each surfaces as a JR escalation when its first call site materializes. Batch-sweep plan at `/Users/verdagon/.claude/plans/lets-do-proactive-please-proud-feather.md` — ~1.5 hours, structural-only (bodies stay `panic!`). +- **Revisit `/// Arena-allocated` vs `/// Temporary state` classifications.** Scaffolding may have over-eagerly marked types Arena-allocated when they're really transient solver outputs or function-return wrappers (`LocationInFunctionEnvironmentT`, `CompleteResolveSolve`/`CompleteDefineSolve`, `HinputsT`). Walk every `/// Arena-allocated` type and re-classify ones that don't need arena identity. Architect-level decision per type. +- **Wrapper enums (IEnvironmentT family) reclassified as Polyvalue** per @TFITCX; the closed-set-fat-pointer mental model + by-value eq/hash trap documented at @PVECFPZ. `IEnvironmentT`/`IInDenizenEnvironmentT` are now held by value at field/parameter sites with derived eq/hash. +- **SPDMX recurring class: structural-shape diff that's a Rust→Scala bug-fix.** Seen on `compiler_tests.rs:1102-1114` (the "Automatically drops struct" test, where the Rust pattern was matching `template_args` against the OwnT/StructTT coord but Scala's third `FunctionNameT` field is `parameters`); SPDMX flagged the corrective re-shape. If it fires again, worth amending into SPDMX rather than temp-disabling each time. +- **`RUST_MIN_STACK=16777216` set globally in `/Volumes/V/Sylvan/.cargo/config.toml`** — debug-mode workaround for postparser `scout_expression`'s giant per-arm-locals frame bloat (~21KB/frame; 96 frames of normal recursion exhausts the default 2MB stack on `typing_pass_on_roguelike`). Release builds pass unmodified. **Post-migration TODO: revert the config change** once `scout_expression` is split per-arm into helper fns (or its `(StackFrame, &IExpressionSE, VariableUses, VariableUses)`-tuple locals are Boxed) so default stack suffices in debug too. +- **Eliminate sources of nondeterminism.** Ptr-hashing on `@IEOIBZ` identity types, `IdT`, and `PtrKey` is nondeterministic across runs and leaks into output via `HashMap`/`HashSet` iteration. `ArenaIndexMap` (insertion-ordered) is unaffected — the AASSNCMCX sweep accidentally fixed most cases. Remaining at-risk: `HashMap, V>` in `CompilerOutputs` and `HashMap` in `HinputsT` (both Temporary state). **Short-term:** extend ArenaIndexMap to ptr-hashed-key maps regardless of containing-struct class. **Long-term:** content-based hashing on `@IEOIBZ` types + `IdT` (touches the @IEOIBZ pattern). Bit-reproducible output requires both. Defer until the instantiator gets attention or a test flakes. + +- **NMSFX-bypass workflow exception for SCPX `FILE_MAP` registrations.** Adding entries to `Luz/shields/ScalaCommentParity-SCPX/src/main.rs`'s `FILE_MAP` constant is a registration table edit (not shield-logic), routinely needed during pass-migration. For TL: use `guardian-ordain` if the session needs a pass on file-scope shields (NMSFX temp-disable doesn't work for file-scope shields, only function-scope). For JR: escalate to TL when NMSFX fires on FILE_MAP. Documented further in `FrontendRust/docs/migration/migration-policy.md`. + +- **PSMX: no Python (or other scripting) edits to source.** During the simplifying-pass rollout one set of bulk renames + cfg-gating was done via inline `python3 << EOF ... open(p,'w').write(...) EOF` scripts — that's a PSMX violation even when the end state is correct. Use the Edit tool for bulk operations (decompose into individual edits) or escalate to architect for a different approach. Applies to TL and JR equally. + +- **Bare-placeholder pattern for cross-pass scaffolding.** When TL needs to scaffold a type whose upstream module isn't migrated yet (typical: H-side simplifying code references I-side instantiating types, or simplifying references finalast types that haven't been ported), use the bare-placeholder pattern: canonical Scala name, `_marker: PhantomData<…>` absorbing type/lifetime params, no doc-comment, no `#[derive]`, `// TODO: populate fields when exposes them` note. Full Scala shape stays in the adjacent `/* … */` block per SCPX. Documented in `FrontendRust/docs/migration/migration-policy.md` and `.claude/agents/slice-placehold.md`. Not for JR — JR emits full-shape stubs; TL switches to bare-placeholder mode when forced by upstream incompleteness. + +- **NAGDX vs slice-placehold dispatcher conflict resolved.** Slice-placehold no longer emits `/* Guardian: disable-all */` on enum dispatchers (was conflicting with NAGDX which prohibits adding any `Guardian:` text). When NNDX fires on the new dispatcher fn, JR escalates to TL via `for-tl.md`; TL evaluates and (if approved) adds the directive manually — TL/architect are exempt from NAGDX per the existing TL-exception policy. + +- **Slice-pipeline "done" = SCPX green only. Cargo green is NOT a pipeline goal.** Placeholder stubs from slice-placehold naturally reference types that don't exist yet (upstream-pass output AST, cross-pass input types whose own ast isn't exposed, etc.) — `cargo check` is allowed to be red after the pipeline runs, and chasing it during the pipeline phase produces a lot of premature scaffolding work (cross-pass type stubs, `use` statements, lifetime decoration, exception-extension churn). The next phase — Guardian-enabled real migration — is where stubs get filled in and references resolve as test paths drive the work. Codified in `docs/skills/slice-pipeline.md`: Step 8 (SCPX) is the only verification. Burned ~half a session on this during the simplifying rollout; the bare-placeholder scaffolds + I-side exposure that resulted are kept in place (not rolled back per architect call) but were not actually needed at that point. + +--- + +## Good Partial Implementing + +When replacing a `panic!` stub with real logic, write just the shallow structure of that scope — straight-line variable bindings, function calls, match expressions with all arms — but put `panic!` inside every new branch body, loop body, closure/lambda body, and match arm. Then only fill in the specific arms/branches the driving test actually hits. This applies recursively: when a test hits one of those inner panics, replace *that* panic with its own skeleton-with-panics, fill in only what the test needs, and so on. Each iteration expands one panic into a new layer of structure. **Aggressively panic for anything that might not be executed by current tests.** This minimizes each batch's diff and ensures untested paths crash loudly rather than silently returning wrong results. + +**"Untested branches" means untested *code paths*, not untested *data values*.** A struct field initialized to `HashMap::new()` runs on the test path — if Scala produces an empty map on the same input, the empty Rust map is correct parity. Panic only inside branches that wouldn't be reached if the input is empty: loop bodies iterating empty collections, match arms for variants the input doesn't contain, closures that are never invoked. When in doubt: does this line *run* on the test path? Yes → produce Scala's value (empty is fine). No → panic. + +**SPDMX caveat.** SPDMX sees `.map(|x| panic!())` / `.for_each(|x| panic!())` / nested `for x in ... { panic!() }` and flags it as "novel scaffolding," recommending whole-function `panic!()` instead. Whole-function panic breaks the test path, so the skeleton-with-panics IS the right pattern. **Resolution: TL temp-disables SPDMX on the affected function** (juniors must escalate, not temp-disable themselves). Standard rationale boilerplate: + +> Per TL.md "Good Partial Implementing": this function uses the skeleton-with-panics-in-closures pattern that the migration design endorses. The iteration structure (.map / .for_each / nested for) mirrors Scala's call graph; panics live in the closure bodies. SPDMX's heuristic flags the iteration structure as "novel scaffolding," but the structure IS the Scala parity — without it, the call graph diverges. For the empty-input case (the driving test), the closures never fire and the function is a verified no-op; for non-empty inputs they panic loudly with named placeholders. TL approval: temp-disable SPDMX here, re-enable when the closure bodies get filled in with real logic. + +Expect this on most emitter-shaped typing-pass functions (long `.map.groupBy.mapValues` / `.foreach` chains). Re-enable SPDMX when the closure bodies get filled with real logic. + +--- + +## Architect Approval Required + +**Run structural solutions by the architect first.** Before implementing any structural fix or design change, propose the solution and wait for approval. This also applies to anything you write into `for-jr.md` — get architect approval before handing instructions to JR, even when the answer looks obvious. This includes lifetime-parameter additions, signature changes that propagate across many files, new abstractions, and any choice between alternatives. Don't start editing — even for fixes that look mechanical — until the architect has signed off. The cost of a quick check is small; the cost of unwinding a wrong-direction change across ~20 call sites is large. + +**Never add `// AFTERM:` or `// TODO:` comments** — yours or JR's. These markers are the architect's tool for tracking deferred cleanup; they get added only when the architect explicitly asks. This applies even when the deferral seems obviously correct (a needless snapshot, a misplaced helper, a panic stub that clearly needs real logic). Raise the deferral to the architect; don't park it inline. If JR proposes an AFTERM/TODO, tell them to drop it and escalate. + +--- + +## TL Does Only What JR Can't — Guardian-Blocked Changes Only + +**Default to letting JR do the work.** TL/architect intervention is reserved for changes that Guardian would block JR on, or that require explicit architect approval per other rules in this doc. Concretely, TL handles: + +- **NNDX-blocked definition adds** (new fn / struct / trait / enum / impl with no Scala line-for-line counterpart): per "NNDX Escalation Pattern" above. +- **SPDMX-blocked skeleton-with-panics** patterns: per "Skeleton-With-Panics vs SPDMX" above — TL issues the temp-disable. +- **Scala source edits** to match a Rust simplification: per "Editing Scala To Match A Rust Simplification" above — TL/architect-only. +- **Guardian annotations** for new definitions without Scala counterparts: per "Guardian Annotations For New Definitions Without Scala Counterparts" — TL adds `/* Guardian: disable-all */` or empty `/* */` blocks. +- **Test-traversal / large test infrastructure** with no Scala line-for-line counterpart: per slab 15f's `traverse.rs` precedent. +- **Structural / lifetime / cross-file refactors** that need architect sign-off per "Run Solutions By The Architect First." + +**Everything else is JR's job, including signature shape changes that don't trip Guardian.** Adding an `interner` parameter to a method is JR's call — they don't need to escalate. Adding `&'t self` where needed for back-pointer-emitting methods is JR's call. Renaming a parameter from `env` to `nenv` to match Scala is JR's call. Threading a new field through three call sites is JR's call. The line is "would Guardian fire on this edit?" — if no, JR does it; if yes, TL does it. + +**JR can issue Guardian temp-disables themselves** via `mcp__guardian__guardian_temp_disable`; they only escalate to TL when the temp-disable itself fails or is rejected. + +**Threading an `interner: &TypingInterner<'s, 't>` parameter is always a fine Rust adaptation** — Scala didn't take an interner because it used GC, but Rust often needs one to arena-allocate a result Scala mutated in place. Document with `// Rust adaptation (SPDMX-B): ` above the fn. JR-level work; doesn't trip Guardian. + +**When JR escalates something Guardian wouldn't have blocked (e.g. a lifetime error with a documented arena-alloc shape), hand the fix back as instructions for JR to apply — don't land it yourself.** + +--- + +## Cleaning Up After The Slice Pipeline + +The slice pipeline (`slice-start` → `slice-rustify` → `slice-placehold` → reconcile) is the right tool for bringing a file with raw `/* scala */` comments up to SCPX parity. It's also incomplete in known ways. After running it on a non-trivial typing-pass file, plan on a manual cleanup pass before `cargo check` will be clean. These are the lessons from running it on `env/environment.rs`. + +### `slice-placehold` doesn't infer struct context + +For each `// mig: fn foo` it emits `pub fn foo<'s, 't>(&self, …) { panic!() }` at **module scope**. It does not look at what Scala class the `def` is inside, and it does not wrap the stub in an `impl SomeT<'s, 't>` block. + +Two failure modes follow: + +1. **Cross-variant name collisions.** A Scala trait method overridden by N case classes (e.g. `lookupWithNameInner` overridden by `PackageEnvironmentT`, `CitizenEnvironmentT`, `ExportEnvironmentT`, `ExternEnvironmentT`, `GeneralEnvironmentT`) becomes N module-level `pub fn lookup_with_name_inner` stubs that all collide (`E0428`). +2. **Invalid `&self`.** `&self` outside an `impl`/`trait` is not valid Rust (`E0061`-style) and the per-fn `<'s, 't>` generics on a free fn don't have anywhere to come from in a real method dispatch. + +**Cleanup**: wrap each stub in the right `impl<'s, 't> SomeT<'s, 't> where 's: 't { … }` block, **drop the per-fn `<'s, 't>` generics** (the impl provides them), and indent the existing Scala `/* … */` to live inside the impl alongside the Rust fn (per the SCPX adjacency rule, §"Preserve The `/* scala */` Audit Trail" in the design doc). One impl block per stub matches the rest of the file's pattern; consolidating multiple methods into one impl is allowed but not required. + +### `slice-placehold` emits bogus `eq`/`hash_code` stubs + +Scala's `override def equals/hashCode` is realized in Rust by `impl PartialEq`/`impl Hash`, not by methods named `eq`/`hash_code`. The placehold agent will sometimes emit `pub fn hash_code(&self) -> i32 { panic!() }` stubs that don't correspond to any real Rust dispatch. + +**Cleanup**: replace the bogus `pub fn` body with a one-line marker comment: +```rust +// mig: fn hash_code +// (Realized by `impl Hash for FooT` below.) +/* + override def hashCode(): Int = … +*/ +``` +Keep the `// mig:` marker (preserves the audit trail) and the Scala `/* … */` block (SCPX). Just don't pretend there's a Rust method. + +### NRDX blocks multi-fn diffs — go one fn at a time + +The `NoRenamedDefinitions-NRDX` shield's heuristic flags consecutive context-swaps as renames. An Edit that wraps **two adjacent** `// mig: fn foo` and `// mig: fn bar` stubs in their impl blocks in one shot will trip the shield with "fn foo renamed to bar" — even though no rename is happening. + +**Cleanup**: do one stub per Edit. Slow but predictable. + +### Verify with cargo + SCPX after + +After cleanup, two checks: + +1. `cargo check --manifest-path FrontendRust/Cargo.toml --lib > tmp/.txt 2>&1` — must be 0 errors. Pre-existing warnings are fine; new ones aren't. +2. `cargo run --manifest-path Luz/shields/ScalaCommentParity-SCPX/Cargo.toml --release -- --check-all` — must report `All 230 files OK`. SCPX is the canary that the audit trail is intact through the wrap. + +### Don't dispatch the orchestrator on a hand-edited file + +The slice-orchestrator runs all six steps. If the file already has hand-written Rust impls (like `env/environment.rs` did before this session), reconcile-mark only catches the matching-name old definitions and leaves the rest in place. The colliding fresh placehold stubs then need the manual `impl`-wrap cleanup above. Plan for it; don't expect the orchestrator alone to leave a compile-clean file when the input was mid-state. + +--- + +## Proactively Add Inherited Dispatch Methods + +The slice pipeline only stubs methods defined directly on a Scala trait's body. Scala trait-extends-trait inheritance, abstract factory methods, and dispatch-tag enums all need explicit Rust delegation the pipeline doesn't generate. When you see a Scala child trait extending a parent (or a sealed trait with named implementors per SSTREX), proactively add all inherited dispatch methods on the child enum — don't wait for serial JR escalations. See "Slicing In New Definitions" below for the slice-in mechanics; annotate the new methods with `/* Guardian: disable-all */`. + +--- + +## Slicing In New Definitions + +When JR is blocked by NNDX on a legitimate Scala counterpart, the issue is incomplete scaffolding, not a bad shield — TL adds the missing definition directly (don't temp-disable NNDX). The junior escalating is the system working correctly. + +**Pre-flight.** Grep the target type for existing `pub fn`s — JR sometimes proposes a Rust-idiomatic name (`step`) when the Scala-parity port already exists under the operator translation (`add` for `def +`). Recent miss: JR's `life.step(1)` escalation when `add(interner, n)` already lived at `ast/ast.rs:387`. + +**Escalation hygiene.** JR should cite the Scala source (`Frontend/.../X.scala:NNN`), not the Rust audit-trail line. + +**How to slice in.** Find the Scala `def` inside its `/* ... */` block; split the block — close `*/` just before the target `def`, insert the Rust `impl`, reopen `/*` for the remaining Scala. The Scala `def` line must end up **inside** the Rust `impl` block, as an inline `/* ... */` immediately after the Rust `fn` body — not after the `impl`'s closing brace. + +```rust ++*/ ++impl<'s, 't> IEnvironmentT<'s, 't> where 's: 't { ++ pub fn global_env(&self) -> &'t GlobalEnvironmentT<'s, 't> { ++ match self { ++ IEnvironmentT::Package(e) => e.global_env, ++ // ... ++ } ++ } ++ /* + def globalEnv: GlobalEnvironment ++ */ ++} ++/* +``` + +Note how the existing scala code is unchanged, and we are making an addition *around* it. + +### Sub-case: name-collision disambiguation + +Rust flattens multiple Scala compiler classes (`Compiler`, `ImplCompiler`, `TemplataCompiler`, ...) onto one `Compiler` struct. Same-named Scala methods (e.g. `Compiler`'s anonymous `IInfererDelegate.isDescendant(kind: KindT)` and `ImplCompiler.isDescendant(kind: ISubKindTT)`) collide at compile time. Append a `_` suffix to the *newer / less-established* slice — leave existing call sites intact. Add a comment above the new fn: + +```rust +// Rust adaptation: collides with Compiler::is_descendant lifted from +// ImplCompiler.scala (which Rust flattened onto Compiler); appended `_kind` +// suffix. Scala uses class-level disambiguation that Rust lacks. +``` + +NNDX fires on the rename, so this is TL territory. Don't reach for materializing an `IInfererDelegate` struct unless the architect signs off — the flatten-onto-Compiler convention is precedent since `sanity_check_conclusion`. + +### Sub-case: no Scala counterpart at all + +For Rust definitions with no Scala counterpart (delegation wiring for Scala trait inheritance, `From`/`TryFrom` impls, interning Val/Query structs), annotate so Guardian doesn't re-fire: + +- **Pure wiring (no logic)** — delegation methods, `From`/`TryFrom` match-dispatches, trivial forwarding accessors. Add `/* Guardian: disable-all */` after the fn/impl block. +- **Contains logic** — conditionals, assertions, non-trivial transformations. Add an empty `/* */` after the body (satisfies SCPX, signals "reviewed and has no Scala counterpart"). + +JR never adds these annotations — they escalate to TL. + +--- + +## Preserve The `/* scala */` Audit Trail + +The typing/ skeleton has a `/* ... */` block with the Scala source directly below every Rust definition. The `.claude/hooks/check-scala-comments` pre-commit hook does exact-match comparison and rejects any edit inside those blocks. Rules: + +- Replace the empty Rust stub in-place with the real definition. Keep the Scala `/* ... */` block below unchanged. +- Never move a Rust definition away from its Scala block. +- A Rust definition grown to need helper structs (e.g. an IdValT companion for an IdT) gets its companion block **adjacent to** the main definition, with a `// (no scala counterpart — …)` note. +- **After any change that touches Scala comment blocks** (splitting, moving, adding new impl blocks between them), run the SCPX shield to verify structural integrity: + ``` + cargo run --manifest-path Luz/shields/ScalaCommentParity-SCPX/Cargo.toml --release -- --check-all + ``` + +--- + +## Writing Scala-Parity Tests + +Scala tests built on `Collector.only(scope, { case … })` should port to the existing `collect_only_*node!` traverse macros (`postparsing/test/traverse.rs`, `typing/test/traverse.rs`) — one macro call per Scala `Collector.only` call, the whole `case` pattern inlined verbatim — not to positional `expect_N` + `cast!` + `assert_eq!` chains, which over-constrain on element count and are invisible to a tree walker. Use literal patterns where Scala does: `StrI<'s>` is `pub struct StrI<'s>(pub &'s str)`, so `StrI("x")` matches inline exactly like Scala's `StrI("x")` — no `if name.as_str() == "x"` guard needed. Trailing `VoidSE` from semicolon-terminated blocks is invisible to recursive collectors, so don't add Rust-only stripping in the scout to "fix" a port — rewrite the over-constrained test instead. + +## Test Promotion Workflow + +All 173 tests in `src/typing/test/` have `#[ignore]` except the currently-active test. This means `cargo nextest run` only runs the active test(s), so JR sees regressions immediately — a failure means something they changed broke, not a pre-existing panic. + +**When JR reports a test passing:** +1. Verify the pass yourself: `cargo nextest run --manifest-path ./FrontendRust/Cargo.toml > ./tmp/slab15-tests.txt 2>&1` +2. Remove `#[ignore]` from the next simplest test in `compiler_tests.rs` +3. Hand off to JR again + +**Choosing the next test:** Start with `compiler_tests.rs` (91 tests, simplest programs). Within that file, go roughly top-to-bottom — the tests are ordered from simple to complex. Once `compiler_tests.rs` is done, move to `compiler_solver_tests.rs`, then `compiler_virtual_tests.rs`, etc. + +**Keep passed tests un-ignored.** They serve as regression guards. If a passed test starts failing, that's a real regression JR needs to fix before continuing. + +--- + +## Commit Message Format + +When the architect says "fire commit," structure the message as: + +1. **First line: 1–3-sentence TL;DR** of what this commit does. The whole summary fits on the first line (no hard wrap into the body); think headline, not subject. Tools that show only the first line should give the reader the gist. +2. **Body: what the commit contains** — paragraph(s) describing the changes in enough detail that a reviewer can verify scope without reading the diff. Group by file or by concern, whichever reads better. +3. **Trailing list: notable situations / new arcana / complicated comments.** Bullet list at the end calling out anything unusual: scaffolding fixes that needed architect approval, new arcana documents created, Guardian temp-disables added, comments inserted that explain non-obvious invariants, Scala source edits, etc. Empty list is fine — omit the section if nothing notable happened. + +Use a HEREDOC to preserve formatting (per the standard commit protocol). Don't add a Co-Authored-By trailer unless the architect explicitly asks for one. + +--- + +## JR Escalations Land In `for-tl.md` + +JR writes every escalation (scaffolding gap, NNDX block, SPDMX skeleton, lifetime puzzle, alternatives needing a call) into `for-tl.md` at the repo root. **Check `for-tl.md` at the start of every turn** and whenever the architect hands work back without a specific escalation in chat — it's the source of truth for what JR is blocked on. Chat mentions are courtesy; the file is canonical. After resolving an escalation, strike the section (or remove it) so the file shows only open items. + +When the architect says just "z", that's the signal to check `for-tl.md` for something new that you must address. After resolving each escalation, propose to the architect one preventive tweak (e.g. a sentence to add to `docs/skills/migration-drive.md`) so the same class of escalation doesn't recur. Always Read the actual Rust/Scala files JR cites — line numbers and snippets in `for-tl.md` are JR's framing, and the real code often contradicts or complicates their summary. Also grep TL.md and `docs/architecture/typing-pass-design-v3.md` for keywords from JR's question — the answer (or a directly relevant precedent) is often already written down. When you finish handling an escalation, write the response/instructions for JR into `for-jr.md` at the repo root so JR can pick it up between turns. + +--- + +## How To Continue + +1. **Read the design doc** (`docs/architecture/typing-pass-design-v3.md`) top to bottom — Part 1 covers the arena shape. +2. **Body migration is test-driven.** The active test (most recently `tests_panic_return_type` as of Slab 15i; the next `#[ignore]`'d test in `compiler_tests.rs` order becomes the driving target) drives which panic stubs get implemented. See "Test Promotion Workflow" above. +3. **Only commit when the architect says "fire commit".** Hand back uncommitted working trees at batch boundaries by default. The architect handles tags. When (and only when) the architect says the literal phrase "fire commit," run `git commit` with a message in the format below. +4. **Group related bodies** into coherent batches for review. Each batch gets a handoff doc listing target methods, driving test(s), and Scala translation gotchas. Spawn a junior per batch. Expect and invite push-back — handoffs are proposals, not spec. +5. **When a design diverges from the design doc, record the divergence in `FrontendRust/docs/reasoning/.md`, then update the design doc.** +6. **Scope discipline.** If edits land in `TL.md`, the design doc, or reasoning docs, announce in the hand-back summary, not folded silently into the diff. Revert off-scope edits before review. + +--- + +Questions? The reasoning docs + the per-slab handoffs have additional context. When in doubt, prefer Scala parity over Rust-idiomatic optimization — that's the guiding principle. diff --git a/diversify-quest-handoff.md b/diversify-quest-handoff.md new file mode 100644 index 000000000..3d1482797 --- /dev/null +++ b/diversify-quest-handoff.md @@ -0,0 +1,984 @@ +# Diversify Quest — Investigation Handoff + +**Date written:** 2026-05-15 +**Branch:** `rustmigrate-z` (uncommitted changes; see "Code state" section) + +## TL;DR + +We're trying to find a cheap, fast LLM model (or model-config combo) that's good enough to replace Sonnet as the SPDMX (Scala Parity During Migration) shield judge in Guardian.

The actual cause is `g_defs: fn`. Root cause: `detect_def_kind_from_diff` (`Guardian/ShieldFile/src/lib.rs:1134`) iterates all lines and returns the **last** def-kind seen; for this case a context line ` trait IPlaceholderSubstituter` overrides the actual `+fn substitute_templatas_in_templata` change. Returns `Some("trait")`, fails the `g_defs: fn` filter. **Guardian bug.** Fix: prefer added-line kinds over context-line kinds. + +- **`variability`: genuinely a coin flip.** Three votes split 2:1 in either direction across runs. Scala reference is just `def variability: VariabilityT` (signature only, no body shown in the diff). Rust fills in one match arm with real logic. Whether this is "Exception P partial migration" (ALLOW) or "novel logic not in Scala" (DENY) is genuinely ambiguous. Likely needs 5-7 votes or richer context (full Scala source). **Possibly the historical verdict was ALLOW, not DENY** — see Finding 4. + +- **`solve_rule`: model commits a decomposition fallacy.** The diff has multiple changes: (a) parameter type changes (`&mut`), (b) body replaced with `panic!`, (c) Scala comment block preserved. Each change individually fits one Exception clause: B (lifetimes/borrowing), A (panic placeholder), K (comments). The model checks each independently, gets a cover, and concludes no violation. What it misses: the Scala body had substantial logic; replacing it with `panic!` is "simplified implementation" (forbidden), not "fresh stub" (Exception A's domain). Root cause: model treats exception-application as per-change rather than per-divergence-as-a-whole. Possible fix: add a rule clause "Exception A doesn't cover replacing existing Scala logic with a panic — only fresh stubs." + +### Finding 3: Two distinct exception mechanisms in ShieldFile + +(Background, not new — but clarifies what the harness is testing.) + +1. **In-line exception application** (in the main shield prompt): the shield text including its `## Exceptions A. B. C. ...` section is sent verbatim to the model. Per @OFPLSCZ ("Observations First, Per-Letter Self-Categorization"), the model writes `reason` first then sets `violation` last, allowing it to reason about exceptions mid-thought. + +2. **Post-hoc per-violation exception fork** (`exc0`, `exc1`, …): when the main check returns violations and `allow_exceptions=true`, ShieldFile runs a second LLM call per violation using `Guardian/ShieldFile/exception-check-template.txt` to re-categorize as A-X, Y, or Z. A-X dismisses; Z (or unknown) preserves. This is at `lib.rs:952-997`. + +Our with/without `GUARDIAN_ALLOW_EXCEPTIONS` comparison showed mechanism #2 is essentially silent for ling — the main check is already setting `violation: false` directly, so there's nothing for the fork to re-categorize. + +### Finding 4: Claude backend caught only 6/17 — premise may be broken + +Final run: ran the same 17 cases through `--backend claude` (uses local `claude` CLI with model="sonnet" per `Guardian/Rabble/src/backends/claude.rs:147`). + +**Result: 6/17 caught**, far worse than ling's baseline 12/17.

Useful for confirming the original false-negative mechanism (model returning `{}` because no rule was visible). Not used by current harness. + +## Open questions / suspected bugs + +1. **CRITICAL: ground-truth verdicts for the 17 test cases.** Run the bash one-liner above to dump each case's historical verdict from its `*.SPDMX.SPDMX.verdict.md`. Then re-classify every model's results against true verdict. The "caught" metric needs to become "true_positive_rate" + "false_positive_rate". + +2. **Is `--backend claude` actually invoking the same Sonnet that produced historical verdicts?** Check: + - `Guardian/Rabble/src/backends/claude.rs:143-147`: tier→model mapping. SimpleMedium → "sonnet". Local `claude --model sonnet` may be Sonnet 4.6 / 4.7 / latest. Historical verdicts predate this session's date (2026-05-15) — they may have been a different snapshot. + - Compare prompt structure. Open `Guardian/tmp/runs/claude-full/SPDMX-baseline/claude/variability/log/.../log.check-direct.0.SPDMX-baseline.vote0.log` and the corresponding historical log at `/Volumes/V/Sylvan/FrontendRust/guardian-logs/request-131-1778778785941/hook-131/log.variability--357.0.ScalaParityDuringMigration-SPDMX.log`. Diff them. + +3. **Guardian bug: `detect_def_kind_from_diff` returns last detected kind.** `Guardian/ShieldFile/src/lib.rs:1134`. For a contextified diff with `+fn foo()` early and a context line ` trait Bar {` later, returns `"trait"` and fails `g_defs: fn`. Fix: prefer added-line kinds; report all detected kinds (not just last); or scan only added (`+`) lines. + +4. **Guardian bug: misleading skip-log message.** `Guardian/ContextifiedShield/src/validate.rs:378` logs `(when_mentioned not matched)` for any Ok(None) return, including defs-filter mismatch. Should report the actual reason. + +5. **Decomposition fallacy fix for SPDMX rule.** Add to `## Exceptions` clause A (or as a meta-clause): "Exception A and similar placeholder-related exceptions cover replacing a *fresh* panic stub with logic. They do NOT cover replacing existing Scala logic with a panic. If the Scala comment block contains a non-trivial implementation, replacing it with `panic!()` is a simplified-implementation violation, not a panic-stub fill-in." + +6. **Add a "checks the whole diff" step.** After listing exception applications, ask the model: "Considered as a whole, do the exceptions you cited cover ALL the divergences between Rust and Scala in this diff? Or are there divergences that none of your cited exceptions cover?" Two-pass prompt structure may help (described earlier in session notes but not implemented). + +7. **`run_comparison.py` denial reasons display.** Each denial wraps `violations[]`; current rollup printing reads `denials[].reason` (often empty) instead of `denials[].violations[].reason`. Was fixed mid-session in `progress_print` but verify the CSV row's `denial_count` matches. + +## Reproduction checklist + +For someone picking this up: + +```bash +# 1.

New runs that flag this as DENY are arguably *more* +correct than historical truth. + +## Section 3: Manual review of three contested ALLOW cases + +The three cases where models disagreed most with historical truth were dug into +by hand. Findings: + +### 3a. `evaluate_maybe_virtuality` — historical truth was lenient + +Scala throws `RangedInternalErrorT` and `AbstractMethodOutsideOpenInterface` as +exceptions. The Rust diff changes the signature to +`Result, ICompileErrorT<'s, 't>>` AND replaces the two throw +sites with `panic!`. The "success" arm in the diff was `Some(crate::typing::ast::ast::AbstractT)` +(without `Ok(...)` wrapping). That's a real type-mismatch / unfinished edit. + +The historical Sonnet ALLOWed this, presumably treating the whole change as a +single Result-adaptation gestalt (Exception B). The current file on disk +(`function_compiler_middle_layer.rs:120`) reads `Ok(Some(...))` — fixed in a +later commit. Sonnet baseline and ling baseline both correctly flagged this in +our runs. Sonnet 3v reverted to ALLOW. + +**Implication for analysis**: when computing accuracy, you can score this case +either way. We computed both: strict ground-truth (Sonnet baseline = 9/10) and +"adjusted for the real bug" (Sonnet baseline = 10/10). Reported numbers below +use strict ground-truth unless noted. + +### 3b. `variability` — ling FP confirmed real + +Diff fills in one match arm: `ReferenceMemberLookup(e) => e.variability` (was +`panic!(...)`). Scala reference shows only `def variability: VariabilityT` +(abstract method on the trait). Ling flagged this as a violation arguing "Scala +just declares the method, Rust now contains implementation logic not in the +Scala reference." + +That's wrong. In Scala, case-class constructor params auto-satisfy abstract +`def`s on the parent trait. The `ReferenceMemberLookupTE` case class has +`variability: VariabilityT` as a constructor param, which IS the override. +Rust's `e.variability` is exact parity. Sonnet got this right; ling didn't — +ling lacked the parent case-class definition in its context (referenced_defs +only included `VariabilityT`/`MutabilityT` enums, not the case class). + +This is the case where you'd expect referenced_defs to help. It didn't (see +Section 4) — the prompt's "do not flag violations in these definitions" +preamble seems to push the model toward leniency on the main diff too. + +### 3c. `get_or_evaluate_function_for_header` — ling FP confirmed real + +One-character change: added `?` after `self.assemble_function_params(...)` +because the callee now returns `Result`. Pure error-propagation. Scala uses +exceptions; Rust uses `?`. Classic Exception B. Ling flagged it as "Rust adding +error handling Scala doesn't have." + +Both `variability` and `gofh` are FPs that ling repeats consistently across +runs. They share a structure: **a `?` or Result-conversion at the surface, with +no novel semantic logic underneath.** Ling can't distinguish surface +Result-adaptation from semantic divergence reliably. + +## Section 4: All experimental runs (this session) + +All runs target the same 10 cases.

After +inspecting per-vote outputs, this is **not** a bug or noise — it's voting +working correctly and revealing what the model actually believes. + +Recall the aggregation: majority of votes that deny → result is union of all +denying votes' violations. With independent samples this drives toward the +model's true deny-rate `p`: +- 1v: caught with probability `p` +- 3v: caught with probability `p² · (3 − 2p)` ≈ `p³ + 3p²(1−p)` +- At `p = 0.5`: 1v → 0.5, 3v → 0.5 (no change) +- At `p = 0.7`: 1v → 0.7, 3v → 0.784 +- At `p = 0.3`: 1v → 0.3, 3v → 0.216 + +So 3-vote PUSHES OUT from 0.5 — toward the model's actual conviction. If the +model is wrong with conviction (`p` high but on a truth-ALLOW case), 3v makes +it more wrong. If the model is borderline-right by luck (`p` ≈ 0.4 on a +truth-DENY case), 3v makes it wronger. + +### 6a.

Why the original 17-case set showed voting helping + +Hypothesized but unverified: the 17-case set likely had more cases where the +model's deny-rate sat above 0.5 on a real DENY (`p > 0.5` truth-D), so voting +nudged 0.7 → 0.78, 0.6 → 0.65, accumulating +2 catches. This addendum's +10-case set has more borderline-but-wrong cases — including several real +ALLOWs where the model has high deny conviction — which voting also amplifies +in the wrong direction. Larger sample needed to confirm. A useful next step +would be: rerun the 17 cases with 3-vote, check per-vote deny rates per case. + +## Section 7: Referenced defs experiment + +Hypothesis: ling's FPs on `variability` and `gofh` were caused by missing +context (parent case-class definitions / callee signatures). Including +referenced_defs should fix at least some of them. + +**Result: refs HURT both ling and Sonnet.** See Section 4 table: + +| Model | accuracy w/o refs | accuracy w/ refs | delta | +|---|---|---|---| +| ling-1t 1v | 7/10 (5 TP, 3 FP) | 4/10 (2 TP, 3 FP) | lost 3 TPs | +| sonnet 1v | 9/10 (5 TP, 1 FP) | 8/10 (3 TP, 0 FP) | lost 2 TPs | + +ling-1t with refs still flagged `variability`, `evaluate_maybe_virtuality`, +and `gofh` as DENY — refs did NOT fix the originally-hypothesized misclassifications. +Both models became uniformly *more lenient* on real DENYs and gained ~0 +correctness on FPs. + +**Working theory** (unverified, worth investigating): the prompt template for +`definition-with-refs` prepends the refs block with "do NOT flag violations +in these definitions." This framing may be priming the model to view the whole +diff as "context I shouldn't be aggressive about." The leniency leaked from +the refs section into the main diff judgment. A cleaner experiment would be to +include refs WITHOUT the "do not flag" preamble, or word it differently +("these are background symbols; analyze only the main diff" rather than "do +not flag violations"). + +Prompt template location: search for "Referenced Definitions" or "Do NOT flag" +in `Guardian/ShieldFile/src/lib.rs`. + +## Section 8: Detailed failure-mode analysis for ling family + +Across single-vote and 3-vote runs, ling's failures cluster around a single +structural pattern: **changes whose visible surface is Result/error-handling +adaptation.** + +Type A — real DENYs that LOOK like Result-adaptation but contain novel logic: +- `evaluate_expected_address_expression`: changes parent_ranges argument + passing AND inserts `?` propagation. Ling sees `?`, applies Exception B, + misses the argument change. +- `evaluate_addressible_lookup`: wraps in `Ok(...)` AND adds an unrelated + match arm. Same blind spot. +- `report_when_multiple_types_in_array`: replaces unmigrated test stub with + a complete novel arena/parser-setup test body. Some ling models miss this + as "test migration" (Exception A territory) without checking whether the + body is faithful to the Scala test. + +Type B — real ALLOWs that LOOK like Result-adaptation: +- `get_or_evaluate_function_for_header`: literally one added `?`. Pure + propagation, no novel logic. Ling sees the `?` and classifies as "Rust + adding error-handling Scala doesn't have." +- `variability`: replaces panic stub with field access on a case-class + param. Ling lacks the Scala case-class semantics to know fields auto-impl + abstract defs. + +**Both failure modes spring from the same root cause**: the model can spot +"this involves Result/`?`/error-handling" but cannot reliably determine +whether the adaptation is purely surface (allow under Exception B) or hides +semantic divergence (deny). It applies the exception by lexical pattern, not +by semantic analysis. + +This is the same "decomposition fallacy" mentioned in the first half of this +document under `solve_rule`, but scoped specifically to Result/error-handling +adaptations rather than general per-change decomposition. + +Sonnet does distinguish these cases. On `gofh`, Sonnet correctly noted "the +only change is a `?` propagation for a callee that now returns Result." On +`eeae`, Sonnet noticed the `parent_ranges` argument list was passed +incorrectly. Sonnet is doing the semantic check; ling is not. + +## Section 9: Recommendation and what to verify next + +### Decision (per user) + +Commit to **ling-2.6-flash at 1 vote** as the Sonnet replacement for SPDMX. +Provider config: `Guardian/provider-configs/ling-2.6-flash.json`. + +Rationale: +- Matches ling-2.6-1t accuracy at ~4× the speed (5.6s vs 20.0s per case) +- 7/10 on this 10-case set; **expected true accuracy ~5-6/10 once voting + noise is accounted for** (Section 6) +- Cheapest credible option — every other OpenRouter model either underflagged + catastrophically or had setup problems +- 3v made it worse, refs made it worse: don't enable those without a + follow-up study + +### Knowns for the researcher + +1. **The "voting helps ling" finding in the original handoff is unstable.** + It held on the 17-case set, broke completely on this 10-case set. Either + the 17-case truth was unreliable (the original handoff explicitly flags + this as urgent open question #1) or the 17-case set had a different mix of + model-conviction distributions. Worth re-running 17 cases at 3v and + tabulating per-vote deny-rates per case (vs final-majority) to characterize + the model's distribution shape. +2. **Single-vote accuracy = sample of true belief. Multi-vote accuracy = + converged true belief.** When you want a stable estimate, vote. When you + want lucky tail-event catches, don't. +3. **Ling's blind spot is Result/error-handling adaptations.** Both directions + (false positive AND false negative). Same structure, opposite labels. + Any prompt-engineering work on the SPDMX shield should target this + specifically. Candidate intervention: an explicit "test" in the shield + that asks the model to enumerate every change and label each as + (surface-adaptation / semantic-divergence) before reaching a verdict. +4. **Referenced defs hurt accuracy when included with the current prompt + wording.** Either fix the wording or don't include them. Counter-intuitive + enough to warrant an isolated experiment. +5. **deepseek-v4-flash was never fairly tested** (50% API timeout rate). + If the researcher wants another data point for the "is there ANY cheap + reliable model?" question, this is the one to rerun with `--parallel 1` + and a longer timeout. +6. **Three models are confirmed too lenient regardless of prompt**: + deepseek-v3.2 (6/10, 2 TP), kimi-k2.5 (6/10, 2 TP), devstral-2512 (6/10, + 1 TP), mimo-v2.5-pro (6/10, 1 TP). These would let real bugs through. +7. **gpt-oss-20b at 5 votes was no better than ling at 3 votes** despite + more samples. 4/10 with 4 FPs. Not a candidate. + +### Suggested next experiments for the researcher + +1. **Bigger sample.** This 10-case set is tiny and skewed (5 DENY, 5 ALLOW, + 3 of the 5 ALLOWs are Result-adaptation-shaped — overrepresented vs + real-world frequency). Once 50+ post-restart DENYs accumulate, re-do this + with a stratified sample of ~30 DENYs + ~30 ALLOWs. +2. **Per-vote distribution sweep.** For each model × each case, run 10 + single-shot votes and compute the actual deny-probability. Then you can + tell which cases are "model conviction" vs "model coin flip", which is + what determines whether voting helps or hurts. +3. **Refs prompt rewording.** Run ling-flash 1v with three refs-prompt + variants: current ("do not flag violations in these"), neutral + ("these are background context"), and skeptical ("these are background; + pay extra attention to the main diff"). See if leniency leak goes away. +4. **Targeted SPDMX rule tightening.** Add an explicit Exception clause: + "Exception B (lifetime/error-handling adaptation) applies ONLY when the + change is purely propagation — adding `?`, wrapping success in `Ok(...)`, + converting `throw` to `Err`. It does NOT cover replacing Scala body logic + with `panic!()`, nor changes that combine error-handling with novel + argument or control-flow modifications.

Output types carry `<'s, 't>` — they can hold `&'s` refs into the scout arena. Heavy templatas hold `&'s FunctionA` / `&'s StructA` directly. No re-interning, no side tables for origin data. Envs allocate into the typing arena. + +**The trade.** Cost: scout arena memory (FunctionA/StructA/etc.) retained through instantiation; typing arena memory (envs, typing-pass output) retained through instantiation. Rough estimate: hundreds of MB to a few GB for large programs. Fine for batch compilation; reconsider for long-running LSP-style use (see Risks / Open Questions). Benefit: the port maps to Scala line-for-line in most places. No side-table plumbing. Faster to implement, easier to review for Scala parity. + +### 1.1 Three Arenas + +- **`'p` — Parser arena (`ParseArena<'p>`)**: parser AST, `StrI<'p>`, coords. +- **`'s` — Scout arena (`ScoutArena<'s>`)**: postparser + higher-typing output (`FunctionA<'s>`, `StructA<'s>`, etc.), interned postparser names (`INameS<'s>`, `IRuneS<'s>`, `IImpreciseNameS<'s>`). Unchanged for the typing pass. +- **`'t` — Typing arena (`TypingInterner<'t>`)**: interned typing-pass types (names, kinds, coords, templatas), typing-pass output AST (function defs, expressions, `HinputsT`), **and typing-pass environments** (`IEnvironmentT` and its 9 concrete variants). Created before the typing pass; outlives the typing pass. + +All three arenas use `bumpalo`. Arena-allocated structs follow AASSNCMCX: no `Vec`/`HashMap`/`String` inside arena types. + +### 1.2 Lifetime Invariants + +1. **`'s` outlives `'t`**. Expressed as `where 's: 't` on every output type that transitively holds `&'s` data. Rust does not enforce outlives via drop order — we must declare the bound. Representative structs that carry this bound include `HinputsT<'s, 't>`, `IEnvironmentT<'s, 't>`, `KindT<'s, 't>`, and every interned typing-pass type. +2. **`'t` outlives the typing pass.** Created by the caller before the pass; dropped by the caller after the instantiator is done. +3. **`'s` outlives the instantiator**, because `HinputsT<'s, 't>` contains `&'s` refs. Scout arena drops after the instantiator completes (or later). +4. **Only two arena lifetimes beyond `'p`:** `'s` and `'t`. Envs live in `'t` (with `&'s`-lifetimed content like `FunctionA` refs and `INameS` references flowing through via field types). +5. **Arena borrow convention.** Arena parameters use a short borrow lifetime (elided or named `'ctx`), never the arena's own lifetime. Write `&ScoutArena<'s>` or `&'ctx ScoutArena<'s>`, never `&'s ScoutArena<'s>`. Same for the typing arena. The decoupling works because `arena.alloc(&self, val: T) -> &'t mut T` returns arena-lifetimed data from a short `&self` borrow — callers don't need to hold the arena for all of `'t`/`'s` just to allocate into it. + +### 1.3 Arena Construction Order + +``` +fn top_level_driver() { + let parse_arena = ParseArena::new(); + // ... parser produces parser AST into 'p ... + + let scout_arena = ScoutArena::new(); + // ... postparser/higher-typing produce into 's ... + + let typing_bump = Bump::new(); + let typing_interner = TypingInterner::new(&typing_bump); + let hinputs = run_typing_pass(&scout_arena, &typing_interner, ... ); + + // ... instantiator runs over HinputsT<'s, 't> ... + + // typing_interner / typing_bump drop (after instantiator): 't dies + // scout_arena drops: 's dies + // parse_arena drops: 'p dies +} +``` + +Rust's drop order (reverse of declaration) naturally enforces `'t < 's < 'p` lifetime nesting. + +### 1.4 Where Each Type Lives + +| Type | Lifetimes | Arena | +|---|---|---| +| `HinputsT` | `<'s, 't>` | `'t` for the struct itself, holds `&'s` and `&'t` refs | +| `FunctionDefinitionT`, `StructDefinitionT`, `InterfaceDefinitionT`, `ImplT`, `EdgeT` | `<'s, 't>` | `'t` | +| `KindT`, `IdT`, `INameT`, `ITemplataT` (all variants) | `<'s, 't>` | `'t`, interned | +| `CoordT` | `<'s, 't>` | inline Copy, not interned | +| `ReferenceExpressionTE`, `AddressExpressionTE` | `<'s, 't>` | `'t`, not interned | +| `OverloadSetT` | `<'s, 't>` | `'t`, interned | +| Heavy templatas (`FunctionTemplataT`, `StructDefinitionTemplataT`, etc.) | `<'s, 't>` | `'t`; hold `&'t` env refs and `&'s FunctionA`/`&'s StructA` directly | +| `IEnvironmentT` and sub-types | `<'s, 't>` | `'t` (allocated in typing arena) | +| `GlobalEnvironmentT` | `<'s, 't>` | `'t`; one per typing pass | +| `CompilerOutputs` | `<'s, 't>` | stack-owned; heap-backed HashMaps; dies at pass end | +| `Compiler` (god struct) | `<'s, 'ctx, 't>` | stack; dies at pass end | + +### 1.5 Type Inventory By Arena + +Bucket-level summary.

Mutable state threads through `&mut CompilerOutputs<'s, 't>` on every call. + +**Not on the god struct:** +- `global_env` — Scala builds `globalEnv` as a local inside `compile()`, not as a constructor arg. We do the same: the top-level env is a method parameter on `compile_program` (and anything downstream that needs it), not a field. +- `name_translator` — Scala's `NameTranslator` is a pure helper class with no state; its methods translate postparser names through the interner. In Rust, every `Compiler` method already has `self.scout_arena` and `self.typing_interner`, so the helper adds nothing. Its ~6 translate methods move directly onto `impl Compiler` and the struct is deleted. + +### 2.2 `&self` + `&mut coutputs` Enables Re-entrancy + +Deep mutual recursion (e.g. `evaluate_expression → evaluate_prefix_call → find_function → evaluate_function_body → evaluate_expression`) works because `&self` allows shared borrow, and `&mut coutputs` is re-borrowed at each call level. With `&mut self`, this would require two simultaneous mutable borrows of the god struct. + +### 2.3 Macros + +Macros (AsSubtypeMacro, LockWeakMacro, StructDropMacro, etc.) were stateful classes in Scala (holding `keywords`, `expressionCompiler`, etc.). In the god-struct refactor, all that state is already on `Compiler`. So macro structs disappear entirely and their methods become ordinary methods on `Compiler`. + +Dispatch is via a small Copy unit-variant enum per Scala macro trait — `FunctionBodyMacro`, `OnStructDefinedMacro`, `OnInterfaceDefinedMacro`, `OnImplDefinedMacro`. Each variant tags which `Compiler` method to call. A given macro may appear in multiple enums iff Scala had it extending multiple traits (e.g. `StructDropMacro extends IFunctionBodyMacro with IOnStructDefinedMacro`). + +### 2.4 Delegate Traits Eliminated + +In Scala, sub-compilers were wired via anonymous delegate traits (IExpressionCompilerDelegate, IFunctionCompilerDelegate, IInfererDelegate, etc.). With the god struct, these are unnecessary — every method calls `self.method(...)` directly. + +### 2.5 Method vs Free Function Under The Collapse + +When porting a Scala `def`, decide method-on-`Compiler` vs free function by inspecting two things: what the **Scala body uses**, and whether the Rust port has to be **stored in a closure**. + +- **Scala body uses no `this`** (no field reads, no method calls on `this` — pure on its arguments) → may become a Rust free function. *Must* become one when the function is stored in a `Box` whose `'static` default would otherwise force a lifetime workaround. Mirror the function name and file location; only the receiver drops. SPDMX exception Q codifies this. Example: `getPuzzles` in the typing-pass solver, `get_puzzles_rune_type` and `get_runes_rune_type` in the postparser solvers. +- **Scala body uses `this`** (reads fields, calls methods on the same class) → must stay a method on `Compiler`, even if the Scala class itself disappears (collapsed by §2.1) or had its methods forwarded through a `delegate: ISomethingDelegate` parameter. The delegate parameter disappears in Rust because §2.4 puts everything on `Compiler`. Example: `solveRule` (was `private def` on `object CompilerRuleSolver`, takes `delegate`; in Rust it's `Compiler::solve_rule(&self, ...)`). + +**Common mistake.** Modeling a typing-pass piece after a postparser solver without checking the body. The postparser solvers (`identifiability_solver.rs`, `rune_type_solver.rs`) have free-function `solve_rule_impl` because they have no `Compiler` and no delegate. Typing-pass code touches the delegate methods constantly — those have to be `&self` methods on `Compiler`. Don't generalize the postparser's free-function shape to the typing pass. + +--- + +## Part 3: Environments + +### 3.1 Arena-Allocated In `'t` + +Environments are allocated directly into the typing arena `'t`. They reference scout data (FunctionA, StructA, INameS) freely via `&'s` fields and reference interned typing-pass data (IdT, ITemplataT, KindT payloads) via the inline wrappers + `&'t` refs. + +**Why `'t`, not `'s`**: envs hold TemplatasStoreT which stores `IEnvEntryT::Templata(ITemplataT<'s, 't>)`, which transitively holds `&'t` refs to interned typing-pass payloads. A struct with lifetime `'s` can only hold `&'x` references where `'x: 's`. Since `'s: 't`, `'t: 's` is false — so `'s`-allocated envs cannot hold `&'t` refs. Envs must live in `'t`. The lifetime ordering is still fine: `'t` outlives the typing pass; envs die together with all other typing-pass output when the typing arena drops. + +Two parallel wrapper enums. Both hold `&'t` refs to the same concrete payloads, so casting between them is stack-only rewraps (no interner involvement). `IInDenizenEnvironmentT` is an 8-variant subset of `IEnvironmentT`'s 9 — the envs that represent "a denizen currently being compiled" (everything except Package). + +``` +pub enum IEnvironmentT<'s, 't> { // 9 variants + Package(&'t PackageEnvironmentT<'s, 't>), + Citizen(&'t CitizenEnvironmentT<'s, 't>), + Function(&'t FunctionEnvironmentT<'s, 't>), + Node(&'t NodeEnvironmentT<'s, 't>), + BuildingWithClosureds(&'t BuildingFunctionEnvironmentWithClosuredsT<'s, 't>), + BuildingWithClosuredsAndTemplateArgs(&'t BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT<'s, 't>), + General(&'t GeneralEnvironmentT<'s, 't>), + Export(&'t ExportEnvironmentT<'s, 't>), + Extern(&'t ExternEnvironmentT<'s, 't>), +} + +pub enum IInDenizenEnvironmentT<'s, 't> { // 8-variant subset (no Package). + Citizen, Function, Node, BuildingWithClosureds, BuildingWithClosuredsAndTemplateArgs, + General, Export, Extern +} +``` + +Every env variant carries `global_env: &'t GlobalEnvironmentT<'s, 't>` as a back-ref (Scala parity; Scala's `IEnvironmentT` has `def globalEnv`). `NodeEnvironmentT` omits it because it delegates via `parent_function_env.global_env` (matching Scala's `override def globalEnv = parentFunctionEnv.globalEnv`). + +`IEnvEntryT<'s, 't>` is a 5-variant Polyvalue enum (@TFITCX / @PVECFPZ): `Function(&'s FunctionA<'s>)`, `Struct(&'s StructA<'s>)`, `Interface(&'s InterfaceA<'s>)`, `Impl(&'s ImplA<'s>)`, `Templata(ITemplataT<'s, 't>)`. Not interned. Lives inline in `TemplatasStoreT.name_to_entry`. + +Env `Hash`/`PartialEq`/`Eq` come from two layers. The Polyvalue wrapper enums (`IEnvironmentT`, `IInDenizenEnvironmentT`) `#[derive(PartialEq, Eq, Hash)]`; the derive delegates into each variant's inner `&'t FooEnvironmentT::eq`, which compares `self.id == other.id`. `IdT` is interned and impls ptr-eq, so the chain reduces to identity equality on the inner arena ref. **Hand-rolling `std::ptr::eq(self, other)` on the outer `&self` would silently break under by-value use** — Polyvalues are held by value (16-byte Copy) at most call sites, and `self` is then a stack address, not the arena address; two by-value copies of `IEnvironmentT::Citizen(same_ref)` would compare unequal. Deriving avoids that trap (see @PVECFPZ). The variant env types (`PackageEnvironmentT`, `CitizenEnvironmentT`, `FunctionEnvironmentT`, `ExportEnvironmentT`, `ExternEnvironmentT`, `BuildingFunctionEnvironmentWithClosuredsT`, `BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT`) keep their manual `self.id == other.id` impls — a documented exception to @IEOIBZ that's sound because `id: IdT` is sealed/canonical (so id-eq is itself ptr-eq under the hood). `NodeEnvironmentT` uses `(id, life)`, `GeneralEnvironmentT` and `TemplatasStoreT` panic with `vcurious` per Scala. Deriving on the variant env types directly would walk into `TemplatasStoreT`'s maps and diverge from Scala. + +### 3.2 `TemplatasStoreT` Uses `ArenaIndexMap` + +For 1:1 Scala parity, `TemplatasStoreT` uses `ArenaIndexMap` (the AASSNCMCX-blessed arena-backed hash map) to mirror Scala's `Map[INameT, IEnvEntry]` and `Map[IImpreciseNameS, Vector[IEnvEntry]]`: + +``` +pub struct TemplatasStoreT<'s, 't> { + pub templatas_store_name: &'t IdT<'s, 't>, + pub name_to_entry: ArenaIndexMap<'t, INameT<'s, 't>, IEnvEntryT<'s, 't>>, + pub imprecise_to_entries: ArenaIndexMap<'t, &'s IImpreciseNameS<'s>, &'t [IEnvEntryT<'s, 't>]>, +} +``` + +- **`name_to_entry`** — `ArenaIndexMap` keyed by `INameT`. Each Scala `entriesByNameT.get(name)` translates to `name_to_entry.get(&name)`. +- **`imprecise_to_entries`** — `ArenaIndexMap` keyed by `&'s IImpreciseNameS`. Values are `&'t [IEnvEntryT]` slices (the per-imprecise-name overload buckets), matching Scala's `Map[IImpreciseNameS, Vector[IEnvEntry]]`. + +`ArenaIndexMap` is not `Copy`/`Clone`, so `TemplatasStoreT` is `/// Arena-allocated` (not value-type). Held as `&'t TemplatasStoreT<'s, 't>` in env structs (matches Scala's GC reference semantics — Scala envs hold a ref to the store, they don't own it). Arena-allocate the store before constructing an env; copy the `&'t` ref into child envs (no clone needed); arena-allocate the result of `add_entries` before storing. `TemplatasStoreBuilder::build_in` already returns `&'t TemplatasStoreT` (allocates internally). + +> **Future exploration:** Once body migration is complete and benchmarks exist, profile lookup-heavy paths (overload resolution, name-imprecise lookups during scout-name-to-typing-pass-name resolution). For env kinds where scope sizes are consistently small (block-local, function-local, node) and lookups are frequent, evaluate switching back to unsorted slice-of-pairs with linear scan on a per-env-kind basis. + +### 3.3 Mutable Building Phase + +During construction, an env is mutable. Builders live on the stack with heap `Vec`s (and heap `HashMap`s for the imprecise-name index); freeze into the typing arena when done. No `&mut FooEnvironmentT` over arena-allocated envs — once a `&'t FooEnvironmentT` is created, it's immutable. Child scopes and mutations produce a fresh builder → fresh arena allocation → fresh `&'t` ref (matches Scala's `NodeEnvironmentBox`, which also allocates a new env per mutation). + +`TemplatasStoreBuilder<'s, 't>` is its own stack builder with `Vec<(INameT, IEnvEntryT)>` for the name-to-entry mapping and `HashMap<&'s IImpreciseNameS<'s>, Vec>>` for the imprecise index (heap during construction, frozen to `ArenaIndexMap` on `build_in`). + +Child-scope API: each env has a `make_child(...)` returning a fresh builder (not a `&mut` over arena-allocated data). Of Scala's mutable wrappers, only `NodeEnvironmentBox` survives in Rust — owned-`Vec`-backed mirror of the Scala wrapper, supporting `&mut self` mutation plus a `snapshot` finalizer. The Box pattern is the natural Rust translation of Scala's `var nodeEnvironment` mutation surface (since arena allocation precludes `&mut NodeEnvironmentT`, and arena slices `&'t [...]` aren't growable in place — see the comment above `pub struct NodeEnvironmentBox` in `function_environment_t.rs`). `FunctionEnvironmentBoxT` is **deleted** in Rust (matches SPDMX exception U); functions previously routed through it now operate on `NodeEnvironmentBox` or `FunctionEnvironmentBuilder`. `IDenizenEnvironmentBoxT` (Scala's trait) is also deleted; the call sites that needed it now route through the concrete env types directly. + +Builders / boxes support **multiple freezes**, not just one. `snapshot(&self, interner)` produces a fresh `&'t T` view at the current state without consuming the builder, so subsequent mutations and later snapshots remain possible. This mirrors Scala's `Box.snapshot`, which is used in `evaluateFunctionBody` to capture a stable "starting env" before running mutations and then pass both the snapshot and the still-mutating box into `evaluateBlockStatements`. Each snapshot allocates a fresh frozen view (cloning the builder's `Vec`/`HashMap` state into the arena); not free, but not hot — call sites are rare enough that correctness wins over micro-optimization. The `snapshot` pattern applies to `TemplatasStoreBuilder`, `NodeEnvironmentBox`, and `FunctionEnvironmentBuilder`. + +**`build_in(self, interner)` (consuming finalizer) lives on the genuine one-shot Rust builders: `TemplatasStoreBuilder`, `BuildingFunctionEnvironmentWithClosuredsBuilder`, and `BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsBuilder`.** These types have no Scala wrapper-equivalent and are used at terminal sites where the `Vec::clone` cost of `snapshot` would be wasted. `NodeEnvironmentBox` and `FunctionEnvironmentBuilder` had their `build_in` deleted: Scala's GC just lets a Box die at scope end with the underlying env living on through references, and no Rust call site needed the consuming form. Code that needs an immutable `&'t T` from either uses `snapshot(&self, interner)` and lets the receiver drop normally. + +### 3.4 Transient Reads Use `&IEnvironmentT` + +Scala's `NodeEnvironmentBox.snapshot` is called ~36 times in ExpressionCompiler.scala, mostly for transient reads. In Rust: + +- **`&IEnvironmentT<'_, 's, 't>`** (elided lifetime) — read-only borrow of the inline wrapper enum. Zero cost, for helpers that only inspect. +- **`&'t IEnvironmentT<'s, 't>`** or **`IEnvironmentT<'s, 't>` by value** — arena-pinned, needed when storing into a parent pointer, output, or a heavy templata. + +Promotion to `&'t` happens only at explicit "store this env" points (via `build_in(interner)` on a builder). Transient reads just use `&`. Since `IEnvironmentT` is itself a Copy wrapper (16 bytes), callers can also pass it by value cheaply. + +### 3.4a `&'t self` On Arena/Interned Types + +Methods on arena-allocated or interned types (`FunctionEnvironmentT`, `NodeEnvironmentT`, `PackageEnvironmentT`, `IdT`, etc.) default to `&self`. Promote to `&'t self` **only** when the method's output borrows from `self` itself — not from a field that's already a `&'t T` ref. + +The distinction in concrete cases: + +- **`&self` is enough** when the output's `'t` traces through a field that already holds `&'t T`. Field-copy-out flattens `&'a (&'t T)` to `&'t T` automatically: `fn templatas(&self) -> &'t TemplatasStoreT { self.templatas }` works under any receiver lifetime, because the field is already `&'t`. +- **`&'t self` is required** when the output's `'t` is `self`'s own arena lifetime. Three concrete shapes trigger it: + 1. **Embed self as a back-pointer** — `fn make_child(&'t self) -> ChildBuilder { ChildBuilder { parent: self, ... } }`. The child holds `parent: &'t Self`; the borrow of `self` must live as long as `'t`. + 2. **Wrap self in a wrapper enum** — `fn lookup(&'t self, ...) { helper(IEnvironmentT::Function(self), ...) }`. The wrap takes `&'t Self` to embed in the variant. + 3. **Return a borrow into a by-value field** — `fn id(&'t self) -> &'t IdT` when `id: IdT` (owned, not a ref). For Copy fields like `IdT`, prefer returning by value to sidestep this entirely. **Important nuance:** the sidestep ("return by value") is only available when *both* the field type and the consumer can flex to by-value. When the consumer is a *struct field* whose type is fixed by Scala parity to be `&'t T` (e.g. `FunctionTemplataT.outer_env: &'t IEnvironmentT<'s, 't>` mirrors Scala's `outerEnv: IEnvironmentT` GC ref), the sidestep isn't available — the embedded ref must be `&'t`. In that case, promote `&'t self` so the field-projection borrow inherits the receiver's `'t` lifetime. Example: `FunctionEnvironmentT::templata(&'t self) -> FunctionTemplataT<'s, 't>` returning `FunctionTemplataT { outer_env: &self.parent_env, function: self.function }` requires `&'t self` because `parent_env: IEnvironmentT<'s, 't>` is a by-value field and the `&self.parent_env` borrow must live `'t` to match `outer_env`'s declared type. + +Pure getters of already-`'t`-ref fields don't need `&'t self`. Promotion is a per-method decision based on the output, not a blanket rule on the type. + +This is a structural cost of mirroring Scala's class-with-back-pointers in arena-allocated Rust — Scala's GC keeps parents alive transitively, so back-references just work; Rust requires the lifetime to be explicit, and on arena types that lifetime is `'t`. The convention is documented here so reviewers don't flag it as a smell. + +### 3.5 `FunctionTemplata` Is A Plain Computed Value + +Matches Scala directly: a method on `FunctionEnvironmentT` allocates a fresh `FunctionTemplataT` into `'t` per call. No caching, no `OnceCell`, no ID minting, no side-table insertion — `FunctionTemplataT` is a small struct holding two pointers, trivially cheap to construct on every call. It's arena-allocated into `'t` but not interned. + +### 3.6 Env-ID Uniqueness Not Required + +Environments don't need unique `id` fields per instance. No HashMap keys on env's own id anywhere in the design: +- `CompilerOutputs.function_name_to_outer_env` etc. are keyed by **function/type template ids** (genuinely unique per Scala's `vassert`). +- OverloadSet holds the env by direct reference, not by id. +- Heavy templatas hold refs, not ids. + +Scala's env-id collisions (NodeEnvironment delegating to parent, GeneralEnvironment reusing caller ids, Box wrappers sharing ids) translate as-is. + +### 3.7 `GlobalEnvironmentT` + +One instance per typing pass, allocated in `'t` early. Every env carries `global_env: &'t GlobalEnvironmentT<'s, 't>` as a back-ref. Holds `name_to_top_level_environment` (slice of `(IdT, TemplatasStoreT)` pairs) and `builtins: TemplatasStoreT`. Scala's macro fields (`nameToFunctionBodyMacro`, etc.) are **dropped** — macros are methods on `Compiler` now (Part 2.3). The struct carries only data. + +### 3.8 Why Not Two-Tier Per-Denizen Arenas (Yet) + +The migration-phase design uses one `'t` typing arena. A post-migration redesign splits into a program-wide `'out` outputs arena and per-top-level-denizen `'scratch` arenas. Full write-up: `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md`. Not in scope for this migration. + +--- + +## Part 4: CompilerOutputs + +### 4.1 Structure + +Mutable accumulator threaded through the pass. Carries `<'s, 't>`. 23 fields: + +- **Function registries.** `return_types_by_signature: HashMap, CoordT>`; `signature_to_function: HashMap, &'t FunctionDefinitionT>`. +- **Declaration tracking.** `function_declared_names: HashMap, RangeS>`; `type_declared_names: HashSet>`. +- **Env back-refs (keyed by function/type template id).** `function_name_to_outer_env`, `function_name_to_inner_env`, `type_name_to_outer_env`, `type_name_to_inner_env` — all `HashMap, IInDenizenEnvironmentT<'s, 't>>`. Narrower in-denizen wrapper, matching Scala. +- **Type metadata.** `type_name_to_mutability: HashMap, ITemplataT>`; `interface_name_to_sealed: HashMap, bool>`. +- **Definitions.** `struct_template_name_to_definition`, `interface_template_name_to_definition` — `HashMap, &'t {Struct|Interface}DefinitionT>`. +- **Impls + reverse indexes.** `all_impls: HashMap, &'t ImplT>`; `sub_citizen_template_to_impls`, `super_interface_template_to_impls` — `HashMap, Vec<&'t ImplT>>` (the two `Vec`-valued exceptions to §4.3, mutated as new impls are discovered; OK because `CompilerOutputs` is stack-owned, not arena-allocated). +- **Exports/externs.** `kind_exports`, `function_exports`, `kind_externs`, `function_externs` — `Vec<&'t {Kind|Function}{Export|Extern}T>`. +- **Instantiation bounds.** `instantiation_name_to_bounds: HashMap, &'t InstantiationBoundArgumentsT>`. +- **Deferred queues.** `deferred_actions: VecDeque`; `finished_deferred_function_body_compiles: HashSet>`; `finished_deferred_function_compiles: HashSet>`. + +No origin side tables — heavy templatas and OverloadSets hold scout refs directly. + +### 4.2 `PtrKey<'t, T>` Newtype For HashMap Keys + +Interned `&'t T` refs hash by pointer identity, not structural equality. Newtype wrapper gives the custom Hash/Eq. Lives in `src/typing/ptr_key.rs`: + +- `PartialEq` uses `std::ptr::eq`. +- `Hash` casts the inner `&'t T` to `*const ()` and hashes that. +- Manual `Copy`/`Clone` (not `#[derive]`) so they work for any `T: ?Sized` without requiring `T: Copy`. The `?Sized` bound is forward-compat for `dyn` / slice keys. + +### 4.3 Side-Table Access Pattern — Copy Out Before &mut + +The env back-refs need the copy-out pattern to satisfy the borrow checker: + +``` +// Does not compile: +let env = coutputs.function_name_to_outer_env.get(&PtrKey(id)).unwrap(); +self.do_stuff(coutputs, env, ...); // &mut coutputs rejected; env borrows from it + +// Works — copy out first: +let env_t: IInDenizenEnvironmentT<'s, 't> = + *coutputs.function_name_to_outer_env.get(&PtrKey(id)).unwrap(); +self.do_stuff(coutputs, env_t, ...); // OK; env_t is Copy'd out +``` + +**Invariant: most HashMap values in `CompilerOutputs` are pointer-sized Copy refs** (`&'s T`, `&'t T`) — enables the copy-out-then-mutate pattern. + +**Two exceptions:** `sub_citizen_template_to_impls` and `super_interface_template_to_impls` hold `Vec<&'t ImplT>` because the reverse-index lookups return multiple impls per key. Access these with `mem::take` / `drain` + reinsert, not by-reference read. + +### 4.4 Deferred Actions + +Avoid `Box` via structured enum: + +``` +pub enum DeferredActionT<'s, 't> { + EvaluateFunctionBody { + prototype: &'t PrototypeT<'s, 't>, + function_env: &'t FunctionEnvironmentT<'s, 't>, + origin: &'s FunctionA<'s>, + }, + EvaluateFunction { + name: &'t IdT<'s, 't>, + calling_env: IInDenizenEnvironmentT<'s, 't>, + origin: &'s FunctionA<'s>, + template_args: &'t [ITemplataT<'s, 't>], + }, + // Add variants as needed. +} +``` + +`function_env` on `EvaluateFunctionBody` is `&'t FunctionEnvironmentT` (the concrete env type, matches Scala). `calling_env` on `EvaluateFunction` is `IInDenizenEnvironmentT` (the narrow wrapper, also matches Scala). + +Drain loop: `pop_front()` → match → call `Compiler` method with `&mut coutputs`. No self-borrow because once the action is popped, it doesn't alias anything inside `coutputs`. No `Box`, no `dyn`, no hidden captures. + +**Invariant:** `DeferredActionT` variants hold only owned or `Copy` context (`&'s` and `&'t` refs, small values). They never reference `CompilerOutputs` itself. + +### 4.5 Speculative Writes Are Idempotent + +During overload resolution, `attempt_candidate_banner` writes to `coutputs` even for candidates that may later be rejected. Safe because writes are idempotent — re-writing asserts equality. No rollback machinery. + +--- + +## Part 5: OverloadSet + +### 5.1 Transient Kind, But Holds Env Directly + +- Overload resolution always completes during the typing pass; nothing unresolved reaches the instantiator. +- But an `OverloadSet`-kinded `ReinterpretTE` survives in output as an inert type tag (the instantiator elides it via `InstantiationBoundArgumentsT.runeToFunctionBoundArg`). + +Since `'s` and `'t` live through instantiation, we hold the env directly — no `ctx_id` indirection needed: + +``` +pub struct OverloadSetT<'s, 't> { + pub env: IInDenizenEnvironmentT<'s, 't>, + pub name: &'s IImpreciseNameS<'s>, // scout-interned, fine to hold +} + +pub enum KindT<'s, 't> { + // ... other variants ... + OverloadSet(&'t OverloadSetT<'s, 't>), +} +``` + +### 5.2 Construction + +A method on Compiler interns an `OverloadSetT { env, name }` into a `KindT::OverloadSet`. No side-table insertion, no `ctx_id`, no `&mut coutputs` required. + +### 5.3 Overload Resolution Uses The Env Directly + +The resolver reads `overload_set.env` directly, walks its parent chain, looks up candidates, recurses into nested OverloadSets via their own `env` fields. Matches Scala's `OverloadResolver.scala:210` pattern verbatim. + +### 5.4 Post-Pass + +`OverloadSetT<'s, 't>` survives in `HinputsT<'s, 't>` inside inert `ReinterpretTE` args. Its env and name refs remain valid for as long as `'t` and `'s` live. The instantiator elides these on sight. + +--- + +## Part 6: Type System Types + +Every lifetime-parameterized struct in this section has an implicit `where 's: 't` bound (§1.2). + +### 6.0 Phantom-`+T`-Erasure Principle + +**Any Scala `+T <: SomeTrait` type parameter is erased to monomorphic widest-form in Rust.** The Rust port carries no leaf-type generic parameter; callers pattern-match at the use site to narrow, just as Scala does at runtime (`+T` is JVM-erased anyway). This applies uniformly to: + +- `IdT[+T <: INameT]` → `IdT<'s, 't>` with `local_name: INameT<'s, 't>` (§6.3) +- `PrototypeT` (no generic in Rust; monomorphic) +- `SignatureT` (no generic in Rust; monomorphic) +- `ITemplataT[+T <: ITemplataType]` → `ITemplataT<'s, 't>` (§6.6) +- `PlaceholderTemplataT[+T <: ITemplataType]` → `PlaceholderTemplataT<'s, 't>` with `tyype: ITemplataType<'s>` (the widest existing postparser enum, *not* `ITemplataT` — the field holds a type *descriptor*, not a templata value) +- `PrototypeTemplataT[T <: IFunctionNameT]` → `PrototypeTemplataT<'s, 't>` (no inner generic; just holds `&'t PrototypeT`) + +Rationale + alternatives are recorded in `FrontendRust/docs/reasoning/idt-typed-view-alternatives.md`. + +**Erasure rule: widen the field to match the bound, not the enclosing trait.** `IdT[+T <: INameT]` has `local_name: T` — the bound is `INameT`, so the erased field is `INameT<'s, 't>`. `PlaceholderTemplataT[+T <: ITemplataType]` has `tyype: T` — the bound is `ITemplataType`, so the erased field is `ITemplataType<'s>`. A common mistake is widening to `ITemplataT<'s, 't>` (the *value* enum), but `ITemplataType` and `ITemplataT` are different type families: `ITemplataType<'s>` is a postparser-defined type *descriptor* ("what kind of templata?" — e.g. `IntegerTemplataType`, `MutabilityTemplataType`), while `ITemplataT<'s, 't>` is an actual templata *value* ("what does this templata hold?" — e.g. `Integer(42)`, `Kind(&'t StructTT)`). `ITemplataType` is `'s`-only because it never holds typing-pass data. + +**No `'t`-lifetime re-interned versions of `StrI`, `IImpreciseNameS`, `RangeS`, `CodeLocationS`, `PackageCoordinate`, `FileCoordinate`.** Use the scout-arena versions directly. Same for `ITemplataType<'s>` — the existing postparsing enum is reused unchanged from typing-pass code. + +### 6.1 IDEPFL Dual-Enum Pattern, Sealing, and Scala-Parity Interning + +The Interned-vs-Value-type rule (Scala's `IInterning` is the spec, plus `IdT` as a Rust-side divergence), the `MustIntern` seal pattern, and the dual-enum (Val + canonical) lookup machinery are documented in @WVSBIZ ("Scala Parity Overrides The Heuristics"), @SICZ, and @DSAUIMZ. Read those before adding a new Interned type. The typing-pass-specific shape: + +**Currently sealed (21 types):** `IdT`, the 15 transient (slice-bearing) Name types (`ImplNameT`, `ImplBoundNameT`, `OverrideDispatcherNameT`, `OverrideDispatcherCaseNameT`, `ExternFunctionNameT`, `FunctionNameT`, `FunctionBoundNameT`, `PredictedFunctionNameT`, `LambdaCallFunctionTemplateNameT`, `LambdaCallFunctionNameT`, `StructNameT`, `InterfaceNameT`, `AnonymousSubstructImplNameT`, `AnonymousSubstructConstructorNameT`, `AnonymousSubstructNameT`), and the 5 kind payloads (`StructTT`, `InterfaceTT`, `StaticSizedArrayTT`, `RuntimeSizedArrayTT`, `OverloadSetT`). The ~57 simple Name types (`PrimitiveNameT`, `PackageTopLevelNameT`, etc.) are Interned per Scala-parity but **not yet sealed** — extending the seal requires `*NameValT` mirrors. Tracked in `FrontendRust/docs/todo.md`. + +**Family-level `intern_*` HashMaps (4 families):** +- `intern_name(INameValT) -> INameT` — names. The 15 transient ones above carry `'tmp` per @DSAUIMZ; the ~57 simple ones reuse the canonical as Val. +- `intern_id(IdValT) -> &'t IdT` — monomorphic, slice-bearing (see §6.3). +- `intern_kind_payload(InternedKindPayloadValT) -> InternedKindPayloadT` — the 5 sealed kind types have `*ValT` mirrors (`StructTTValT`, etc.); `KindPlaceholderT` (Value-type) reuses canonical-as-Val. +- `intern_templata_payload(InternedTemplataPayloadValT) -> InternedTemplataPayloadT` — opt-in dedup. All 5 simple variants (`CoordTemplataT`, `KindTemplataT`, `PlaceholderTemplataT`, `PrototypeTemplataT`, `IsaTemplataT`) are Value-type now; `CoordListTemplataT` keeps a `'tmp` Val for its slice. + +`SignatureT` / `PrototypeT` are Value-type per Scala parity but flow through opt-in `intern_signature` / `intern_prototype` helpers; other sites construct `SignatureT { id }` directly since the inner `IdT` is sealed-canonical. + +**Wrapper enums are NOT interned.** `INameT` + 21 name sub-enums, `KindT` + 3 Kind sub-enums (`ICitizenTT`/`ISubKindTT`/`ISuperKindTT`), and `ITemplataT` are all 16-byte inline Copy values. Sub-enum casts are stack-only rewraps via `From`/`TryFrom`. + +**Val types use content-based Hash, not ptr-based** — so query-Val (`'tmp`) and stored-Val (`'t`) hash consistently. The `ptr::eq` treatment stays for canonical `&'t` refs per @IEOIBZ. + +### 6.2 INameT Hierarchy + +~60 concrete name types, ~21 sub-trait enums. Every name type carries `<'s, 't>`. + +**DAG rule (critical).** Scala's sealed-trait hierarchy is a DAG — some concrete names extend multiple sub-traits (`ExternFunctionNameT extends IFunctionNameT with IFunctionTemplateNameT`, etc.). In Rust this becomes: **a shared concrete name gets a variant in each sub-enum it belongs to.** The same `&'t ExternFunctionNameT` can appear as `IFunctionNameT::ExternFunction(...)` and `IFunctionTemplateNameT::ExternFunction(...)`. + +**Sub-enums are inline-owned Copy values, NOT arena-interned.** Only concrete name types and INameT itself live in the typing arena. The intermediate sub-enums are 16-byte derived-Copy values built on the stack when needed. Casting is a pure stack-only rewrap via `.into()` — no interner round-trip. + +Identity: two concrete names compare via `ptr::eq`. Two owned sub-enum values compare structurally — but since the tag + inner pointer is 16 bytes, this is a 2-word compare and still cheap. + +Bridging via `From for SubEnum` (narrow → wide, infallible) and `TryFrom> for SubEnum` (wide → narrow, fallible, match-and-rewrap on the stack). Real implementations in `names.rs`, no interner involvement. + +**Self-referential variants** (e.g. `ForwarderFunctionNameT.inner: IFunctionNameT<'s, 't>`) are inline-owned; since sub-enums are 16 bytes and Copy they can live directly as struct fields without `Box` or `&'t`. + +### 6.3 `IdT<'s, 't>` — Monomorphic, Interned + +``` +pub struct IdT<'s, 't> +where 's: 't, +{ + pub package_coord: &'s PackageCoordinate<'s>, // scout-lifetimed + pub init_steps: &'t [INameT<'s, 't>], // inline INameT values + pub local_name: INameT<'s, 't>, // always the widest form + pub _must_intern: MustIntern, // seal per @SICZ +} +``` + +Per §6.0, Scala's `IdT[+T <: INameT]` phantom outer parameter is **erased**. Callers that need a specific leaf-name variant pattern-match on `local_name` at the point of use. + +IdT is the one Rust-side divergence from Scala-parity interning per §6.1. Scala leaves `IdT` as a plain case class, but Rust seals it because `IdT::eq` uses pointer comparison on the `init_steps` slice — soundness requires that slice to come from the canonical arena allocation in `intern_id` (see @SICZ). Without sealing, two `IdT` literals with structurally equal `init_steps` would have different slice pointers and compare unequal, which is exactly the original `signature-id-mismatch` bug. + +IdT defines custom PartialEq/Eq/Hash (not derive) per @IEOIBZ: +- `package_coord`: pointer-eq (scout arena canonicalizes PackageCoordinate). +- `init_steps`: slice data pointer + length compare — the typing interner canonicalizes `&'t [INameT]` slices as a whole per IDEPFL, so equal content ⇒ equal slice pointer (guaranteed by the seal). +- `local_name`: structural compare on the inline INameT (16 bytes). + +Interning uses one HashMap per IDEPFL keyed by `IdValT<'s, 't, 'tmp>` (transient, `'tmp`-borrowed init_steps slice). No widen/try_narrow methods — pattern-match instead. + +### 6.4 `CoordT<'s, 't>` — Inline Copy + +`CoordT` holds `ownership: OwnershipT`, `region: RegionT`, `kind: KindT<'s, 't>`. Small (~24 bytes), Copy, passed by value. Not interned — structural eq. + +### 6.5 `KindT<'s, 't>` — Inline Wrapper + +``` +pub enum KindT<'s, 't> { + // Primitives inline (small) + Never(NeverT), Void(VoidT), Int(IntT), Bool(BoolT), Str(StrT), Float(FloatT), + // Non-primitives — &'t refs to interned payloads + Struct(&'t StructTT<'s, 't>), + Interface(&'t InterfaceTT<'s, 't>), + StaticSizedArray(&'t StaticSizedArrayTT<'s, 't>), + RuntimeSizedArray(&'t RuntimeSizedArrayTT<'s, 't>), + KindPlaceholder(&'t KindPlaceholderT<'s, 't>), + OverloadSet(&'t OverloadSetT<'s, 't>), +} +``` + +KindT is **inline-owned** (not arena-interned): 16 bytes tag + ref, Copy. Concrete payloads (StructTT etc.) are arena-interned; the wrapper just tags them. + +Same philosophy for the three Kind sub-enum families (ICitizenTT, ISubKindTT, ISuperKindTT). Casts between them are stack-only rewraps via From/TryFrom. + +### 6.6 `ITemplataT<'s, 't>` — Inline Wrapper, Phantom Parameters Erased + +Per §6.0, Scala's `ITemplataT[+T <: ITemplataType]` outer phantom type parameter is **erased** — the wrapper is a monomorphic `ITemplataT<'s, 't>` enum, and callers that need a specific kind pattern-match on the variant. + +Variants split into three groups: +- **Arena-cached value variants** (`&'t` ref to arena-allocated payload): Coord, Kind, Placeholder, Prototype, Isa, CoordList. Per §6.1 these payloads are now `/// Value-type` per Scala parity (the Templata family doesn't `extend IInterning` in Scala) — but they still flow through `intern_templata_payload` for opt-in dedup. The variant holds an `&'t` ref because the payload lives in the arena; equality on the ref is structural (auto-derived `PartialEq` on the payload struct, recursing into properly-canonical `IdT` and identity-bearing env refs). +- **Inline Copy-value variants**: Mutability, Variability, Ownership, Integer(i64), Boolean(bool), String(StrI<'s>) — *scout-lifetimed, not re-interned*, RuntimeSizedArrayTemplate, StaticSizedArrayTemplate. +- **Heavy templatas** (`&'t` to env-ref-holding payloads): Function, StructDefinition, InterfaceDefinition, ImplDefinition, ExternFunction. + +ITemplataT itself is **inline-owned**, not arena-interned. + +Heavy templata payloads hold `&'t` env refs and `&'s` scout refs: + +``` +pub struct FunctionTemplataT<'s, 't> { + pub outer_env: IInDenizenEnvironmentT<'s, 't>, + pub function: &'s FunctionA<'s>, +} +// StructDefinitionTemplataT / InterfaceDefinitionTemplataT / ImplDefinitionTemplataT +// each hold `IInDenizenEnvironmentT` and one of `&'s StructA` / `&'s InterfaceA` / `&'s ImplA`. +pub struct ExternFunctionTemplataT<'s, 't> { + pub header: &'t FunctionHeaderT<'s, 't>, +} +``` + +Heavy-templata `Eq`/`Hash` per @IEOIBZ: each wrapper just `#[derive(PartialEq, Eq, Hash)]`, which deref-calls into the inner identity-bearing type's manual identity impl. For `FunctionA`/`StructA`/`InterfaceA`/`ImplA`/`FunctionHeaderT` that's `std::ptr::eq`; for the Polyvalue `IEnvironmentT` (@PVECFPZ) it's the derived enum impl, which in turn delegates to each variant env's `self.id == other.id` (resolving to `IdT` ptr-eq). Either way the wrapper doesn't repeat the identity logic. + +`PlaceholderTemplataT.tyype: ITemplataType<'s>` (the widest postparser enum, *not* ITemplataT). The Scala field is `tyype: T` where `T <: ITemplataType` — a *type descriptor*, not a templata value. + +`PrototypeTemplataT`'s Scala inner type parameter is also erased (§6.0) — just holds `&'t PrototypeT<'s, 't>`. + +### 6.7 Mutual Recursion + +Types form a mutually recursive graph (`CoordT → KindT → StructTT → IdT → INameT → ITemplataT → CoordT`). Most links are `&'s` or `&'t` refs — pointer-sized, finite. The name sub-enums are the exception — inline 16-byte tagged pointers, one word larger than a raw ref but still finite and Copy. No `Box`/`Vec` needed. + +--- + +## Part 7: Expression AST + +### 7.1 Three Enums + +- `ReferenceExpressionTE<'s, 't>` — 48 variants (LetNormal, If, While, FunctionCall, Consecutor, Construct, Reinterpret, …). +- `AddressExpressionTE<'s, 't>` — 5 variants (LocalLookup, ReferenceMemberLookup, …). +- `ExpressionTE<'s, 't>` — 2-variant wrapper: `Reference(&'t ReferenceExpressionTE)` / `Address(&'t AddressExpressionTE)`. + +**Narrow-use rule.** `ConstructTE` is the **only** expression node that holds the broad ExpressionTE wrapper. Every other slot uses the specific `&'t ReferenceExpressionTE` or `&'t AddressExpressionTE`. + +### 7.2 Arena-Allocated, Not Interned + +Expression nodes are allocated into `'t` but not deduped. Sub-expressions are `&'t` refs; collections are arena slices. No `*ValT` companions, no intern methods, no From/TryFrom bridges across the wrapper enums. + +`IExpressionResultT<'s, 't>` is a 2-variant inline Copy enum (`Reference(ReferenceResultT) | Address(AddressResultT)`), both result structs hold a single CoordT. + +### 7.3 Derives — `#[derive(PartialEq, Debug)]` Only + +`ConstantFloatTE` holds `f64`, which can't derive Eq/Hash. The whole expression-AST family drops Eq/Hash uniformly. `IExpressionResultT` / `ReferenceResultT` / `AddressResultT` keep the full `Copy, Clone, PartialEq, Eq, Hash, Debug` — they only hold CoordT, no f64 transitively. + +### 7.4 Visitor/Collector Pattern + +Same as parsing/postparsing: `NodeRefT<'s, 't>` enum, `visit_*` functions, entry points, `collect_where_tnodes!`/`collect_only_tnodes!` macros. + +--- + +## Part 8: Error Handling + +### 8.1 `Result` With `?` + +Scala's `throw CompileErrorExceptionT(...)` → `return Err(CompileErrorT::...)` with `?` propagation.

Natural scope exit. + +### 10.2 Instantiator Handoff + +The instantiator receives `HinputsT<'s, 't>` plus both arena references. When it's done, the caller lets local bindings drop in scope order (§1.3): typing interner first, scout arena second, parse arena last. + +--- + +## Part 11: Invariants Summary + +Invariants that aren't fully stated elsewhere in this doc: + +1. **All HashMap keys on interned refs use `PtrKey<'t, T>`** for pointer-based hash/eq. (Caveat: `PtrKey` is wrong for content-canonical types like `IdT` whose own `==` is already pointer-equality on inner fields — wrapping in `PtrKey` would compare outer addresses instead. Use `PtrKey` only for `@IEOIBZ`-style identity types.) +2. **Never use `'static`.** All data must live in `'p`, `'s`, or `'t` (or on the stack). `'static` bypasses the arena system: a `&'static T` has a different pointer than a structurally identical `&'s T`, breaking pointer equality for interned types. See `Luz/shields/NeverUseStaticLifetime-NUSLX.md`. +3. **Don't try to fix a `Box + &self` deferred-borrow with a lifetime parameter.** A boxed closure capturing `&self` keeps that shared borrow live for the full lifetime of the box. Holding the box across other `&self` calls deadlocks the borrow checker — and threading a closure-lifetime parameter (e.g. `'fn_lt` on `SimpleSolverState`) only sidesteps the `'static` default; it doesn't resolve the conflict. The fix is always to drop the receiver: convert the captured method to a free function (§2.5), or pass the data the closure needs by value. Check call sites before proposing lifetime-threading. + +For the rest (`'s` outlives `'t`, AASSNCMCX, copy-out-before-`&mut`, speculative writes idempotent, overload resolution completes, env equality unused, envs live in `'t`, `DeferredActionT` never refs `CompilerOutputs`, arena-param short borrow, +T erasure, Val content-hash, heavy-templata refs) — see §1.1, §1.2, §3.1, §3.6, §4.3, §4.4, §4.5, §5.1, §6.0, §6.1, §6.6. + +--- + +## Risks / Open Questions + +- **LSP / long-running use**: scout arena retention through instantiation is memory-heavy; single-arena typing makes batch-only the safe mode. See `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md`. +- **Post-migration design revisits**: the inline-owned-wrapper philosophy makes casts free but gives up compile-time "this IdT's local_name is a FunctionName" assertions.

Works today but hasn't been measured. Profile before optimizing. +- **Body migration ordering**: the panic stubs have implicit dependency ordering — some bodies call other stubbed methods. The test-driven approach naturally discovers this, but expect some batches to require implementing a chain of 3-5 bodies before a test passes end-to-end. +- **Incremental compilation**: serializing HinputsT to disk requires a serialization boundary that breaks `'s` refs.

Running just `Detects conflict between types`: + +``` +DIAG-ARM-6 +``` + +So Scala matches arm 6: `RuleError(CallResultWasntExpectedType(_, KindTemplataT(StructTT(ShipA))))` — and never falls into the catch-all. The `CallResultWasntExpectedType` is emitted by Scala's `solveCallRule` at `CompilerSolver.scala:1031,1034,1049,1052,1084,1087,1116,1119` — directly from the rule body when `result_rune` is already concluded and the call's expected template doesn't match. **Crucially, that emission has no `InternalSolverError` wrap** because it's a structured type-check rejection, not a commit-step conflict. + +So Scala fires `CallSR` *after* `result_rune` has been concluded by some other rule, lands in the `Some(result) → CallResultWasntExpectedType` branch, and returns a clean shape.

For the conflict test's defining-solve phase, Scala fires: + +``` +idx 0 = LookupSR(ShipA) +idx 1 = CallSR(template=ShipA-coercion → Y_a) +idx 6 = LookupSR(void) ← jumped over 2,3,4,5 +idx 2 = EqualsSR(N, Y_a) +idx 5 = EqualsSR(N, Y_b) ← jumped over 3,4 +idx 7 = CoerceToCoordSR(void) ← jumped over 3,4 +idx 3 = LookupSR(ShipB) +idx 4 = CallSR(template=ShipB-coercion → Y_b) +``` + +When `idx 5` fires (EqualsSR(N, Y_b)) — N is already concluded to `KindTemplata(ShipA)` from `idx 2`, Y_b is unconcluded → takes `Some(left) → commitStep(Y_b := N's value)` → **Y_b := KindTemplata(ShipA)**. Then `idx 4` fires (CallSR for ShipB) with `result_rune=Y_b` already concluded → `Some(result)` branch → `kindIsFromTemplate(ShipA, ShipB-template)` returns false → emits `CallResultWasntExpectedType(StructDef(ShipB), KindTemplata(ShipA))` directly. + +Rust with `.min()` would fire idx 4 *before* idx 5 — CallSR sees `result_rune` unconcluded → `None` branch → `predict_struct(ShipB) → Y_b := ShipB` → `commit_step` discovers Y_b is transitively N and N is already ShipA → `Err(SolverConflict(N, ShipB, ShipA))` → wrapped in `InternalSolverError`. + +The divergence is not subtle; it is the headOption-vs-min decision at the solver core. + +### Side note on Scala's "determinism" + +Scala's `.keySet.headOption` over an `immutable.HashMap[Int, _]` is technically JVM-implementation-defined. In practice it's reproducible because Scala's HashMap, given small Int keys (whose hash is the int itself), produces a stable bucket layout. But: + +- The comment "lowest ID, keep it deterministic" misleads readers into thinking the code does what its Rust transliteration does. +- The "determinism" is incidental to JVM HashMap internals; a Scala upgrade or HashMap-implementation change could alter firing order across the entire test suite without any code change. +- This is fragile by IIIOZ standards (`FrontendRust/docs/arcana/IdenticalInputsIdenticalOutputs-IIIOZ.md`) — pointer-address-style leakage of an implementation detail into output behavior. + +--- + +## What we tried: Scala → `.min` (option a) + +Replaced Scala's `getNextSolvable` body with: + +```scala +val ready = openRuleToPuzzleToRunes.filter(...).keySet +if (ready.isEmpty) None else Some(ready.min) +``` + +Ran the full Scala test suite (`sbt test` against `Frontend/`). + +**Result:** 1043 passed, 43 failed. + +Of those 43, after attributing each failure to its suite (sbt interleaves output, so test names alone are misleading), only **3 are in non-AfterRegions suites** (AfterRegions failures are pre-existing and unrelated): + +1. `CompilerSolverTests` — "Detects conflict between types". +2. `CompilerTests` — "Imm generic can contain imm thing". +3. `HammerTests` — "panic in expr". + +### Triage + +**(1) `Detects conflict between types`** — produces the same `RuleError(InternalSolverError(SolverConflict(KindTemplata(ShipB), KindTemplata(ShipA))))` Rust produces. Fixable by updating the test's arms to match the new shape; 1 file change. *Equivalent error semantically — only the shape changed.* + +**(2) `Imm generic can contain imm thing`** — small valid program: +```vale +struct MyImmContainer imm +where func drop(T)void { value T; } +struct MyMutStruct { } +exported func main() { x = MyImmContainer(MyMutStruct()); } +``` +This is a "should compile, no assertion" test. Under `.headOption` it compiles successfully (well, fails by design because MyMutStruct can't satisfy the imm constraint — but the failure is expected). Under `.min` it fails with **a different error**: +``` +Couldn't find a suitable function drop(MyMutStruct). Rejected candidates: +[3 candidates listed, all failing with different rule-fire-time mismatches] +``` + +The firing-order change made overload resolution fail to find a viable `drop` candidate that the `.headOption` order had found. + +**(3) `panic in expr`** — small valid program: +```vale +exported func main() int { return 3 + __vbi_panic(); } +``` +This SHOULD compile (`3 + never` is well-formed; `never` coerces to any type). Under `.headOption` it does. Under `.min` it fails with: +``` +Couldn't find a suitable function +(i32, never). Rejected candidates: +Candidate 1 (of 4): ... + Conflict on rune (arg 1): was never, now i32 +``` + +The min-order routes the `+` overload-resolution through candidate 1 (i32, i32) first, where it tries to coerce the second arg from `never` to `i32`, hits a commit_step conflict, and bails. Under `.headOption`, the order presumably gets it to a candidate that accepts `never` first, or routes the coercion differently. + +### Significance of failures 2 and 3 + +These two aren't about error-shape pattern matching. The test bodies only call `expectCompilerOutputs()` — they assert that the program compiles. Under `.min`, **legitimate programs that should compile fail to compile** because overload resolution can't find candidates the other firing order found. + +This means Scala's solver framework has *order-dependent overload-resolution behavior* beyond the immediate "where does this error wrap" question. The `.headOption` order isn't just an accidentally-deterministic UI quirk — it's load-bearing for the solver's ability to converge on valid overloads at all. + +### Fixing the humanizer (separate but related) + +Switching to `.min` also surfaced a separate latent bug: `CompilerErrorHumanizer.humanizeRuleError` (`Frontend/TypingPass/src/dev/vale/typing/CompilerErrorHumanizer.scala:436-518`) has no `InternalSolverError` arm and no fallback. Under the old ordering, no test produced an `InternalSolverError` that needed humanizing; under `.min`, several do, and the missing arm crashes with `scala.MatchError`. Adding the arm is a 5-line additive change. It doesn't help the underlying overload-resolution failures (those would still fail, just with a renderable error instead of a MatchError crash), but it's worth recording: there are gaps in the humanizer that this experiment surfaced. + +--- + +## Options considered + +### (a) Switch Scala to `.min` and own the consequences + +Update Scala's `getNextSolvable` to genuinely use `ready.min`. Patch the humanizer's missing `InternalSolverError` arm. Update the conflict test's arms to the new shape. + +**Cost:** The two compile regressions (Imm generic, panic in expr) need genuine solver fixes — not test updates. Each fix requires understanding why the new firing order routes overload resolution down a dead-end candidate, and either (i) reorganizing the rule bodies so they don't depend on firing order, or (ii) reorganizing overload resolution to retry candidates differently. Open-ended; could cascade. + +**Risk:** Two failures surfaced from the small fraction of currently-passing non-AfterRegions tests. There are likely more hidden cases where `.headOption`-order happened to find an overload that `.min`-order can't. The 2 we see may be only the tip; full triage requires implementing fixes and re-running. + +### (b) Make Rust mimic Scala's HashMap-bucket iteration order + +Port the JVM's `immutable.HashMap[Int, _]` bucket-iteration semantics into Rust. Doable in principle — use a deterministic open-addressing map with the same bucket function (`h ^ (h >>> 16)`) and the same initial capacity / load factor. + +**Cost:** Implementation work to write the JVM-compatible HashMap; subtle (Scala's HashMap also rebalances on filter, which interacts with bucket assignments). + +**Risk:** Brittle — Scala version upgrades or JVM changes could break the parity. Violates IIIOZ in spirit: output is determined by a fragile reproduction of an implementation detail rather than by intent. Locks Rust to a frozen Scala HashMap implementation forever. + +### (c) Fix both Scala and Rust to use a principled deterministic order (`.min`) + +Combines (a)'s scope plus the deeper solver work to make overload resolution order-insensitive. Honest, principled outcome. + +**Cost:** Largest. Requires solver-framework reasoning: identifying which rules' bodies have order-dependent side effects, making them converge regardless. May involve splitting some rule kinds, ordering puzzles differently, retrying after partial conclusions, or similar redesign work. + +**Risk:** Big commit, hard to estimate ahead of doing it. + +### (d) Surgical fix to the specific rule body that wraps in `InternalSolverError` + +Change `EqualsSR`'s `Some(left) → commitStep(right := left)` branch to first peek at the right rune's conclusion and emit a `CallResultWasntExpectedType`-style structured error directly when both sides are concluded with different values, bypassing `commit_step`. + +**Cost:** Lower than (c), higher than (a). But this only fixes the *shape* of error for tests that hit `EqualsSR`-with-two-concluded-runes — it doesn't fix `Imm generic` or `panic in expr` because those hit overload-resolution dead-ends, not EqualsSR conflicts. + +**Risk:** Each rule body has its own potential order-sensitivity; (d) is whack-a-mole. + +### (e) Accept the divergence; document it; update Rust tests to match Rust's actual output + +Leave Scala alone. Acknowledge that Rust's `.min` produces a different rule-firing order than Scala's `.headOption`. For the (currently 1) test where this manifests as a different error shape, update the Rust port of the test to match the *wrapped* shape Rust produces. Document this report. When future Rust tests fail with similar order-related shape divergences, apply the same pattern: update the Rust test's arms. + +**Cost:** Low. Per-test test-arm updates as they surface. + +**Risk:** Rust and Scala have genuinely different error shapes for some tests. Reviewers comparing the two need to be aware. Future Scala solver changes could shift either codebase's behavior. The order-dependent solver bugs remain (in both languages). + +**Bonus:** The `#[derive(Debug)]` additions from this investigation should stay — they're broadly useful for diagnostics and SPDMX Exception D allows derive additions freely. + +--- + +## Recommendation + +Option (e). The pragmatic concession is the right one given the migration's priorities: + +- The Scala test author already enumerated 6 acceptable shapes, which acknowledges in code that the precise firing path was indeterminate. The Rust port adds a 7th shape; treat it like the other 5 the author didn't anticipate. +- Options (a) and (c) require non-trivial solver work that's out of scope for the typing-pass migration. +- Option (b) is fragile and ideologically wrong (mimicking a JVM implementation detail). +- Option (d) is whack-a-mole. + +Defer the solver-determinism redesign to post-migration. When the typing pass is done and the codebase is stabilized, revisit. At that point, option (c) becomes attractive — a one-time solver redesign that makes both languages order-insensitive. + +--- + +## Sequels / pointers for the redesign + +- The puzzle definitions at `Frontend/.../CompilerSolver.scala:223-262` and Rust's mirror are the right starting point. Each rule kind's puzzle declares "I'm ready when ANY of these rune sets is fully concluded." That ambiguity is what allows firing-order to matter: many rules become ready simultaneously, and which-first changes which path subsequent rules take. +- The specific divergence point is `EqualsSR(left, right)` with puzzle `Vector(Vector(left), Vector(right))` — it fires when either side is solved, then commits the other side to match. Firing it before vs after a peer `CallSR` that competes for the same result rune determines whether the conflict surfaces as `commit_step → SolverConflict` or as `CallSR Some(result) → CallResultWasntExpectedType`. +- A principled fix might require splitting `EqualsSR` into two phases: a "both-sides-solved-check" rule that fires only when both sides are concluded, and a "propagate" rule that fires when one is. Or: have every `commit_step` failure produce a unified error shape regardless of which rule body triggered it. +- The humanizer gap is independent and worth closing regardless: `humanizeRuleError` needs an `InternalSolverError(_, inner)` arm that delegates to humanize the inner `ISolverError`. Same for the Rust mirror at `FrontendRust/src/typing/compiler_error_humanizer.rs:780`. + +--- + +## Artifacts and trail + +- Scala test file edits, all reverted: `Frontend/Solver/src/dev/vale/solver/SimpleSolverState.scala`, `Frontend/TypingPass/src/dev/vale/typing/CompilerErrorHumanizer.scala`, `Frontend/TypingPass/test/dev/vale/typing/CompilerSolverTests.scala`. +- Rust test body, reverted to placeholder `#[ignore] panic!("Unmigrated...")` for `detects_conflict_between_types`. +- `#[derive(Debug)]` additions across ~18 Rust types — kept (broadly useful, no semantic impact, SPDMX Exception D covers). +- `evaluate_generic_function_from_non_call` `?`-propagation at `FrontendRust/src/typing/compiler.rs:1748-1749` (the fix for `reports_incomplete_solve` from earlier in this session) — kept separately; unrelated to the solver-determinism issue. +- Test promotion: `detects_conflict_between_types` left at `#[ignore]` pending decision on test-arm shape. +- Full Scala test output: `tmp/scala-fulltests-min.txt`. +- Full Rust diagnostic output: `tmp/diag-reports-incomplete.txt`. diff --git a/docs/historical/slab-chronicle.md b/docs/historical/slab-chronicle.md new file mode 100644 index 000000000..22614d82f --- /dev/null +++ b/docs/historical/slab-chronicle.md @@ -0,0 +1,173 @@ +# Typing Pass Migration — Slab Chronicle (Historical) + +**This is a historical record.** The slab-based scaffolding phase (Slabs 0–14b) is complete.

Bodies panic-stubbed. + +### Slab 9 — TemplataCompiler object methods +Free-fn stubs lifted onto `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't`. `interner` and `keywords` parameters dropped (use `self.typing_interner` / `self.keywords`). `bound_arguments_source: &'t dyn IBoundArgumentsSource<'s, 't>` on the 11 substitute_* methods. + +### Slab 10 — Compiler.rs residuals + orphans + TemplataCompiler tail +Flipped `()` placeholders in compiler.rs methods (`preprocess_struct`, `preprocess_interface`, `determine_macros_to_call`, `ensure_deep_exports`, `is_root_function`, `is_root_struct`, `is_root_interface`, `evaluate`) and orphan static fns; filled `local_helper.rs` 2 orphans + `struct_compiler.rs` 1 orphan; filled 14 bare-`(&self)` tail impls in `templata_compiler.rs`.

Solver structs: `InferEnv<'s, 't>`, `InitialKnown`, `InitialSend`, `CompleteDefineSolve`, `CompleteResolveSolve`. `HinputsT::new()` constructor added.

Function-result enum triples: `IDefineFunctionResult`, `IResolveFunctionResult`, `IStampFunctionResult`. `ITypingPassSolverError` (28 variants). Reduced `_Phantom` count from 12 → 1 (only `IRegionNameT` remains, deferred — 0 Scala implementors found). + +--- + +## Ground Rule: Preserve The `/* scala */` Audit Trail + +The typing/ skeleton has a `/* ... */` block with the Scala source directly below every Rust definition.

Rules: + +- Replace the empty Rust stub in-place with the real definition. Keep the Scala `/* ... */` block below unchanged. +- Never move a Rust definition away from its Scala block. +- A Rust definition grown to need helper structs (e.g. an IdValT companion for an IdT) gets its companion block **adjacent to** the main definition, with a `// (no scala counterpart — …)` note. + +--- + +## Per-slab handoff docs + +All per-slab handoff docs live in `FrontendRust/docs/migration/handoff-slab-*.md`.

Three rounds of infrastructure work followed: + +1. **Sealed 21 TFITCX-Interned types** with `MustIntern` (private-constructor witness field per @SICZ): `IdT`, the 15 transient (slice-bearing) Name types, and the 5 Scala-`IInterning` kind payloads. Construction now requires going through the interner. +2. **Reconciled Rust's Interned classification with Scala's `IInterning` trait.** 14 types reclassified to `/// Value-type` (`SignatureT`, `PrototypeT`, `KindPlaceholderT`, all 11 Templata variants, `CoordListTemplataT`). +3. **Pushed identity-equality down to identity-bearing types** per @IEOIBZ. Manual `std::ptr::eq` + `std::ptr::hash` impls on `IEnvironmentT`, `FunctionA`, `StructA`, `InterfaceA`, `ImplA`, `FunctionHeaderT`. Wrapper types just `#[derive(PartialEq, Eq, Hash)]`. Variant env types kept their `self.id == other.id` impls. + +Plus IDEPFL uniformity: added Val mirror types for the 5 sealed kind-payload types. + +### Slab 15c — Env-builder & `&'t self` hardening +While migrating `finish_function_maybe_deferred` → `declare_and_evaluate_function_body`, three blockers addressed at TL/architect level: + +1. **Removed `FunctionEnvironmentBoxT` from Scala** for `declareAndEvaluateFunctionBody` and `evaluateFunctionBody`. Edited Scala source first, updated Rust audit-trail blocks, then changed Rust signatures to `&'t FunctionEnvironmentT` directly. +2. **Eagerly promoted ~23 panic stubs to `&'t self`** across `function_environment_t.rs` and `environment.rs` for wrap-self / embed-self patterns. Doc rule added as design v3 §3.4a. +3. **Added `snapshot(&self, interner)` to `TemplatasStoreBuilder`, `NodeEnvironmentBox`, `FunctionEnvironmentBuilder`** — Scala's `Box.snapshot` semantics. Design v3 §3.3 updated. + +### Slab 15d — NodeEnvironmentBox restructuring + expression-hierarchy equality opt-out +1. **`result()` dispatch added on `ReferenceExpressionTE` and `AddressExpressionTE`.** Slice pipeline emitted module-level free fns; wrapped each in proper `impl` blocks dispatching to per-variant `e.result()` panic stubs. +2. **`NodeEnvironmentBuilder` renamed to `NodeEnvironmentBox`** (architect-level Scala-parity rename). With `snapshot()` added in 15c, the type now has full `Box` semantics. +3. **Reversed design v3 §3.3's "Box deleted in Rust" stance.** Walked the Scala audit-trail block at `function_environment_t.rs:822-1020` and sliced in proper Rust impls adjacent to each Scala `/* def ... */`. Implemented `add_variable`, `get_all_locals`, `mark_local_unstackified`. Panic-stubbed the other 22 methods. +4. **`local_helper.rs` 7 method signatures aligned**: `&NodeEnvironmentT` → `&mut NodeEnvironmentBox`. +5. **Dropped `NodeEnvironmentBox::build_in` and `FunctionEnvironmentBuilder::build_in`** — both Rust-only. Only finalizer is `env.snapshot(...)`. +6. **Dropped `derive(PartialEq)` from the entire expression hierarchy in `expressions.rs`** — mirrors Scala's 52 `vcurious()` equals overrides. Documented as a vcurious-mirror exception. +7. **`migration-drive.md` got two new notes**: TFITCX classification check before adding Clone/Copy/PartialEq derives, and a "re-read this skill on every compaction" note. + +### Slab 15e — first end-to-end test passing +`simple_program_returning_an_int_explicit` is now **green end-to-end**. The body of `Compiler::evaluate`'s post-deferred phase is wired up; eight `Slab 10` panic stubs in `compiler_outputs.rs` filled in; `compile_i_tables` / `make_interface_edge_blueprints` / `ensure_deep_exports` got Scala-shaped skeletons with panics in unhandled branches; `HinputsT` field types reshaped to `Vec<&'t T>`; `lookup_function_by_human_name` ported verbatim. Driving test promoted to `hardcoding_negative_numbers`. + +Three meta-lessons folded into TL.md rules: "untested branches" means code paths not data values; SPDMX-vs-skeleton-with-panics tension resolved via temp-disable; `add_function`'s `signature: &'t SignatureT` is SPDMX-B documented adaptation. + +### Slab 15f — typing-pass test traversal + LetSE scaffolding +`hardcoding_negative_numbers` is now **green end-to-end**. Three pieces of TL/architect scaffolding: + +1. **`src/typing/test/traverse.rs`** (~1740 lines) — Rust analog of Scala's `Collector.only` / `Collector.all`. Mirrors postparsing precedent. `NodeRefT<'s, 't>` enum with ~95 variants, ~75 `visit_*` walkers, 5 `#[macro_export]` macros. Full upfront coverage; stop-at-trait for the 74 `INameT` variants etc. +2. **`get_rune_types_from_pattern`** at `src/higher_typing/patterns.rs` — verbatim port of Scala's `PatternSUtils.getRuneTypesFromPattern` as a free `pub fn`. +3. **`LetExprRuneTypeSolverEnv`** at the bottom of `expression_compiler.rs` — Scala's anonymous `new IRuneTypeSolverEnv { ... }` becomes a named struct + impl block. + +Three meta-lessons: anonymous Scala trait impls map to named per-site Rust structs; test-traversal scaffolding is TL territory; AIMITIPX rule applies to test-traversal patterns (no `if matches!` or guards on `collect_only_tnode!` patterns). + +### AASSNCMCX foundational sweep +1. **AASSNCMCX sweep**: convert all `Vec` / `HashMap` fields on `/// Arena-allocated` structs to `&'t [T]` and `ArenaIndexMap<'t, K, V>`. `InstantiationBoundArgumentsT` and `InstantiationReachableBoundArgumentsT` reclassified `/// Arena-allocated`; `HinputsT` reclassified `/// Temporary state`; `LocationInFunctionEnvironmentT` reclassified `/// Value-type`; `FunctionDefinitionT.header` flipped to `&'t FunctionHeaderT`. +2. **`PtrKey<'t, T>` scope tightened.** Now for `/// Arena-allocated` identity types only. Drops `PtrKey<'t, IdT>` etc. throughout `CompilerOutputs` (~17 fields). +3. **`IInstantiationNameT::template_args()` dispatch added** at `names/names.rs` (NNDX-blocked add — 21 variants). +4. **`IPlaceholderSubstituter` closure-capture fields added** at `templata_compiler.rs` (5 fields mirroring Scala's anonymous-trait-impl). +5. **`FunctionBodyMacro` dispatch wired** (foundational SSTREX port): `name_to_function_body_macro: ArenaIndexMap` field on `GlobalEnvironmentT`; 15-arm dispatch method. +6. **Doc updates**: `arenas.md` got "nothing in an arena is ever mutated" invariant + Mutation Patterns section; `WVSBIZ` broadened to seven-principle decision framework. +7. **Two new residuals** added: nondeterminism elimination and Arena-allocated vs Temporary state revisit. + +Three meta-lessons: anonymous Scala trait impls map to named per-site Rust structs OR dispatch-tag enums depending on shape; JR-level lifetime promotion `&'t self` for embedded-back-pointer cases; `PtrKey` is wrong for canonical-content-hash types. + +### Slab 15i — `tests_panic_return_type` end-to-end +Test passes (program: `import v.builtins.panic.*; exported func main() int { x = { __vbi_panic() }(); }`). Four pieces of TL/architect scaffolding: + +1. **Sanity-check conclusion pipeline ported on Compiler** — `sanity_check_conclusion`, `get_placeholders_in_id`, `get_placeholders_in_templata`, `get_placeholders_in_kind` (sliced into `compiler.rs:225-319`). Both `infer_compiler.rs::make_solver_state` call sites wired. +2. **`is_descendant_kind`/`is_ancestor_kind` sliced in on Compiler** (`compiler.rs:404-430`). Both panic-stubbed; `_kind` suffix per Compiler/ImplCompiler name-collision pattern. +3. **Layer-skip fix in `evaluate_templated_function_from_call_for_prototype`** — delegate to closure-or-light layer, not direct coercion to `BuildingFunctionEnvironmentWithClosuredsT`. +4. **`make_named_env` arena-allocation pattern** at the call site of `get_or_evaluate_templated_function_for_banner`. + +Plus JR-level body migrations: `make_closure_understruct_core` (~150 lines), `make_implicit_drop_function_struct_drop`, `FunctionBodyMacro::generate_function_body` (15-arm dispatch), `IInstantiationNameT::template_args() -> &'t [ITemplataT]` (21-arm dispatch). + +Three meta-lessons: Compiler/ImplCompiler name-collision is a recurring pattern; lifetime errors with established AASSNCMCX shapes are JR-level; pre-existing Guardian-flagged parity gaps fix locally if cheap, else pause. + +### Slab 15j scaffolding round 2 +No new tests passed end-to-end; TL/architect-level infrastructure unblocking JR on `simple_struct_read`. + +1. **`IInDenizenEnvironmentT::Export` and `::Extern` variants added** (`env/environment.rs:298`). +2. **`ISubKindTT` trimmed to 3 variants** (`types/types.rs:419`). +3. **`solve_call_rule` slice-pipeline cleanup** (`infer/compiler_solver.rs:1727`). +4. **Structural `PartialEq, Eq` derived on `InstantiationBoundArgumentsT` and `InstantiationReachableBoundArgumentsT`**. +5. **`IFunctionNameT::parameters()` (literal Scala port) + `INameT::parameters()` (Rust adaptation)**. +6. **Top-of-file callout: "JR does not have access to TL.md"**. +7. **`migration-drive.md` one-shot lifetime fix rule**. +8. **Orphan-sweep plan written** at `/Users/verdagon/.claude/plans/lets-do-proactive-please-proud-feather.md`. + +Three meta-lessons: identity vs value-bag is decided by Scala equality story not TFITCX; rustc-suggested lifetime fixes are JR-level even when they cascade; cross-check JR's Guardian-verdict reports against the verdict file. diff --git a/docs/historical/typing-pass-design-v1.md b/docs/historical/typing-pass-design-v1.md new file mode 100644 index 000000000..64a44904c --- /dev/null +++ b/docs/historical/typing-pass-design-v1.md @@ -0,0 +1,544 @@ +# DO NOT FOLLOW — Historical, Obsolete (v1) + +> **This document is historical and obsolete.** It was the first-cut typing-pass design (the `'a` interner arena + `'t` typing arena, two-lifetime model) and was superseded by v2 (Apr 14, 2026), then by `typing-pass-migration-setup.md` (Apr 20, 2026), and finally by the current authoritative design in **`TL-HANDOFF.md` at the repository root**. +> +> Its arena model, lifetime conventions, type families, and slab plan are all wrong relative to the shipping code.

Longest-lived. Managed by the existing `Interner<'a>`. + +- **`'t` — Typing pass arena (new)**: Holds everything produced by the typing pass — both interned type-system values and output AST nodes. Managed by a new `TypingInterner<'a, 't>`. Dies when the typing pass output is no longer needed. + +The relationship: `'a` outlives `'t`. Typing-pass types hold `&'a` references to interner data and `&'t` references to other typing-pass data. + +Previous passes follow the same pattern: `'p` for the parser arena, `'s` for the postparser arena. The typing pass adds `'t`. + +### 1.2 `TypingInterner<'a, 't>` + +A new struct that owns the `'t` arena and provides interning (deduplication) for typing-pass types. Structurally identical to the existing `Interner<'a>` but scoped to the typing pass. + +```rust +struct TypingInterner<'a, 't> { + arena: &'t bumpalo::Bump, + + // Interning maps: owned Val key → canonical &'t ref + coord_map: RefCell, &'t CoordT<'a, 't>>>, + kind_map: RefCell, &'t KindT<'a, 't>>>, + name_map: RefCell, &'t INameT<'a, 't>>>, + templata_map: RefCell, &'t ITemplataT<'a, 't>>>, + id_map: RefCell, &'t IdT<'a, 't>>>, + prototype_map: RefCell, &'t PrototypeT<'a, 't>>>, + // Sub-enum maps as needed (IFunctionNameT, IStructNameT, etc.) +} +``` + +Uses `RefCell` for interior mutability (same pattern as the existing `Interner`). Interning methods take `&self` and mutate the internal maps. + +The interning flow follows IDEPFL: +1. Build an owned Val with all data inline (children already canonical `&'t` refs) +2. Look it up in the HashMap — if found, return existing `&'t` ref +3. If new, allocate into the `'t` arena via `arena.alloc(...)`, store the mapping, return `&'t` ref + +### 1.3 What Goes In Each Arena + +**`'a` interner arena (existing, unchanged):** +- `StrI<'a>` — interned strings +- `PackageCoordinate<'a>`, `FileCoordinate<'a>` — source locations +- `INameS<'a>`, `IRuneS<'a>`, `IImpreciseNameS<'a>` — postparsing names +- `FunctionA<'a, 's>`, `StructA<'a, 's>`, `InterfaceA<'a, 's>`, `ImplA<'a, 's>` — higher-typing output (referenced by typing-pass environments) + +**`'t` typing arena (new) — interned types (deduplicated via `TypingInterner`):** +- `INameT<'a, 't>` hierarchy (~60 concrete types) +- `IdT<'a, 't>` — package coord + name path + local name +- `CoordT<'a, 't>` — ownership + region + kind +- `KindT<'a, 't>` — all variants (primitives and complex) +- `ITemplataT<'a, 't>` — template argument values +- `PrototypeT<'a, 't>` — function prototype (id + return type) +- `SignatureT<'a, 't>` — function signature + +**`'t` typing arena (new) — output AST nodes (allocated but not deduplicated):** +- `FunctionDefinitionT<'a, 't>` — compiled function with header + body +- `FunctionHeaderT<'a, 't>` — function signature + attributes +- `StructDefinitionT<'a, 't>` — compiled struct +- `InterfaceDefinitionT<'a, 't>` — compiled interface +- `ImplT<'a, 't>` — compiled impl +- `EdgeT<'a, 't>`, `OverrideT<'a, 't>` — interface dispatch tables +- `ParameterT<'a, 't>` — function parameters +- `ReferenceExpressionTE<'a, 't>` — reference expression nodes (~38 variants) +- `AddressExpressionTE<'a, 't>` — address expression nodes (~6 variants) +- `ILocalVariableT<'a, 't>` — local variable declarations +- `InstantiationBoundArgumentsT<'a, 't>` — bound arguments per instantiation +- `HinputsT<'a, 't>` — the final output of the typing pass + +**Neither arena (heap or stack):** +- `Rc>` — environments (reference-counted, build-then-freeze) +- `CompilerOutputs<'a, 's, 't>` — mutable accumulator (stack-owned) +- `NodeEnvironmentBox`, `FunctionEnvironmentBoxT` — mutable wrappers (stack-local) +- `GlobalEnvironment` — heap-allocated, holds macros and top-level stores +- `TemplatasStore` — owned by environments (inside Rc) +- Deferred compilation closures — `Box`, heap-allocated + +--- + +## Part 2: The God Struct + +### 2.1 Architecture + +All ~15 Scala sub-compiler classes (`FunctionCompiler`, `ExpressionCompiler`, `StructCompiler`, `ImplCompiler`, `OverloadResolver`, `InferCompiler`, `TemplataCompiler`, `ConvertHelper`, `DestructorCompiler`, `VirtualCompiler`, `SequenceCompiler`, `ArrayCompiler`, `EdgeCompiler`, `BlockCompiler`, `PatternCompiler`, `CallCompiler`, `LocalHelper`) are collapsed into methods on a single struct. + +```rust +struct Compiler<'a, 's, 'ctx, 't> { + interner: &'ctx Interner<'a>, + typing_interner: &'ctx TypingInterner<'a, 't>, + keywords: &'ctx Keywords<'a>, + opts: &'ctx TypingPassOptions, + global_env: &'ctx GlobalEnvironment<'a, 's, 't>, + name_translator: NameTranslator<'a>, + // ... other immutable config +} +``` + +### 2.2 Why This Works: `&self` + `&mut coutputs` + +The god struct holds only **immutable configuration**. All mutable state is passed as separate `&mut` parameters: + +```rust +impl<'a, 's, 'ctx, 't> Compiler<'a, 's, 'ctx, 't> { + fn evaluate_expression( + &self, + coutputs: &mut CompilerOutputs<'a, 's, 't>, + nenv: &mut NodeEnvironmentBox<'a, 's, 't>, + expr: &IExpressionSE<'a, 's>, + ) -> Result, CompileErrorT<'a, 't>> { + // ... + } +} +``` + +This avoids the re-entrancy problem. The typing pass has deep mutual recursion: + +``` +evaluate_expression → evaluate_prefix_call → find_function → evaluate_function_for_header + → evaluate_block_statements → evaluate_expression (re-entrant!) +``` + +With `&mut self`, this chain would require two simultaneous mutable borrows. But with `&self` (immutable config) plus `&mut coutputs` (passed through), re-entrancy on `&self` is fine — multiple immutable borrows are allowed. The `&mut coutputs` is re-borrowed at each call level, which Rust handles naturally. + +### 2.3 Macros + +In Scala, macro objects (`AsSubtypeMacro`, `LockWeakMacro`, `StructDropMacro`, etc.) store references to sub-compilers (`expressionCompiler`, `destructorCompiler`, etc.). In the god struct approach, macros **cannot** store references to the god struct (that would be self-referential). + +Instead, macros receive the god struct at call time: + +```rust +trait IFunctionGenerator<'a, 's, 't> { + fn generate( + &self, + compiler: &Compiler<'a, 's, '_, 't>, // receives god struct as parameter + coutputs: &mut CompilerOutputs<'a, 's, 't>, + env: &FunctionEnvironmentT<'a, 's, 't>, + // ... + ) -> FunctionHeaderT<'a, 't>; +} +``` + +Macros are stored in `GlobalEnvironment` and are stateless — they hold only configuration data (like their name), not compiler references. All compilation logic goes through the `compiler` parameter they receive. + +### 2.4 Delegate Traits Eliminated + +In Scala, the sub-compilers were wired via anonymous delegate traits (`IExpressionCompilerDelegate`, `IFunctionCompilerDelegate`, `IBlockCompilerDelegate`, `IInfererDelegate`, etc.) that forwarded calls between sub-compilers. With the god struct, these are unnecessary — every method is on the same struct and can call any other method directly via `self.method_name(...)`. + +--- + +## Part 3: `CompilerOutputs` + +### 3.1 Structure + +`CompilerOutputs` is a mutable struct with ~25 `HashMap`/`HashSet`/`VecDeque` fields. It accumulates all compiled definitions, environment mappings, instantiation bounds, and deferred evaluation queues. + +```rust +pub struct CompilerOutputs<'a, 's, 't> { + // Function registries + return_types_by_signature: HashMap<&'t SignatureT<'a, 't>, &'t CoordT<'a, 't>>, + signature_to_function: HashMap<&'t SignatureT<'a, 't>, &'t FunctionDefinitionT<'a, 't>>, + env_by_function_signature: HashMap<&'t SignatureT<'a, 't>, Rc>>, + + // Declaration tracking (prevents infinite recursion) + function_declared_names: HashMap<&'t IdT<'a, 't>, RangeS<'a>>, + type_declared_names: HashSet<&'t IdT<'a, 't>>, + + // Environment storage + function_name_to_outer_env: HashMap<&'t IdT<'a, 't>, Rc>>, + function_name_to_inner_env: HashMap<&'t IdT<'a, 't>, Rc>>, + type_name_to_outer_env: HashMap<&'t IdT<'a, 't>, Rc>>, + type_name_to_inner_env: HashMap<&'t IdT<'a, 't>, Rc>>, + + // Type metadata + type_name_to_mutability: HashMap<&'t IdT<'a, 't>, &'t ITemplataT<'a, 't>>, + interface_name_to_sealed: HashMap<&'t IdT<'a, 't>, bool>, + + // Definitions + struct_template_name_to_definition: HashMap<&'t IdT<'a, 't>, &'t StructDefinitionT<'a, 't>>, + interface_template_name_to_definition: HashMap<&'t IdT<'a, 't>, &'t InterfaceDefinitionT<'a, 't>>, + + // Impls + reverse indexes + all_impls: HashMap<&'t IdT<'a, 't>, &'t ImplT<'a, 't>>, + sub_citizen_template_to_impls: HashMap<&'t IdT<'a, 't>, Vec<&'t ImplT<'a, 't>>>, + super_interface_template_to_impls: HashMap<&'t IdT<'a, 't>, Vec<&'t ImplT<'a, 't>>>, + + // Exports/externs + kind_exports: Vec<&'t KindExportT<'a, 't>>, + function_exports: Vec<&'t FunctionExportT<'a, 't>>, + kind_externs: Vec<&'t KindExternT<'a, 't>>, + function_externs: Vec<&'t FunctionExternT<'a, 't>>, + + // Instantiation bounds + instantiation_name_to_bounds: HashMap<&'t IdT<'a, 't>, &'t InstantiationBoundArgumentsT<'a, 't>>, + + // Deferred evaluation queues (see 3.2) + deferred_function_body_compiles: VecDeque>, + finished_deferred_function_body_compiles: HashSet<&'t PrototypeT<'a, 't>>, + deferred_function_compiles: VecDeque>, + finished_deferred_function_compiles: HashSet<&'t IdT<'a, 't>>, +} +``` + +### 3.2 Deferred Evaluation Queues + +Scala uses `LinkedHashMap` for FIFO-ordered deferred queues with O(1) key lookup. In Rust, we use `VecDeque` + `HashSet`: + +```rust +struct DeferredEvaluatingFunctionBody<'a, 's, 't> { + prototype: &'t PrototypeT<'a, 't>, + call: Box, &mut CompilerOutputs<'a, 's, 't>) + 't>, +} +``` + +The drain loop takes-then-calls to avoid self-referential borrow: + +```rust +while let Some(deferred) = coutputs.deferred_function_body_compiles.pop_front() { + // Closure is now owned, removed from coutputs + // Safe to pass &mut coutputs to the closure + (deferred.call)(self, coutputs); + coutputs.finished_deferred_function_body_compiles.insert(deferred.prototype); +} +``` + +The nested drain loop structure matches Scala: drain all `deferred_function_compiles` first (inner while), then process one `deferred_function_body_compiles` entry, then re-check (outer while). Deferred body compilation can enqueue more deferred function compilations, which is why the outer loop repeats. + +### 3.3 Speculative Writes Are Safe + +During overload resolution, `attemptCandidateBanner` writes to `coutputs` (e.g., `addInstantiationBounds`) even for candidates that may later be rejected. This is safe because all writes are **idempotent** — re-writing the same value asserts equality (`vassert(existing == instantiationBoundArgs)`). No rollback mechanism is needed. + +### 3.4 HashMap Keys Are Interned Pointers + +All `HashMap` keys in `CompilerOutputs` are `&'t` references to interned values (mostly `&'t IdT`). Since `IdT` is interned in the `TypingInterner`, pointer equality is identity equality. `Hash`/`Eq` impls on the reference type use pointer-based comparison, making lookups O(1) without structural traversal. + +--- + +## Part 4: Type System Types + +### 4.1 IDEPFL Dual-Enum Pattern + +All interned typing-pass types use the IDEPFL dual-enum pattern (reference enum + value enum), interned into the `'t` arena via `TypingInterner`. + +The interned type families: +- `INameT` / `INameValT` (~60 variants each) +- `IdT` / `IdValT` +- `CoordT` / `CoordValT` +- `KindT` / `KindValT` +- `ITemplataT` / `ITemplataValT` +- `PrototypeT` / `PrototypeValT` +- `SignatureT` / `SignatureValT` +- Sub-enums (`IFunctionNameT` / `IFunctionNameValT`, `IStructNameT` / `IStructNameValT`, etc.) + +Val versions hold owned data for HashMap lookup. For fields that contain other interned types, the shallow pattern applies: the Val holds the already-canonical `&'t` reference. Children must always be interned before parents (bottom-up construction). + +Types that are **not** interned in Scala (`CoordT`, `KindT`, `ITemplataT`) are still interned in Rust for consistency and to enable pointer-based identity throughout. Non-interned types in Val name variants (like `templateArgs` containing `ITemplataT` values) hold canonical `&'t` refs since `ITemplataT` is also interned. + +### 4.2 The `INameT` Hierarchy + +~60 concrete name types organized into ~14 sub-trait enums. Each level of the Scala sealed-trait hierarchy becomes its own Rust enum. Types appearing in multiple sub-traits (DAG pattern) get variants in each relevant sub-enum. + +```rust +// Top-level enum +pub enum INameT<'a, 't> { + FunctionName(&'t FunctionNameT<'a, 't>), + StructTemplate(&'t StructTemplateNameT<'a>), + KindPlaceholder(&'t KindPlaceholderNameT<'a, 't>), + // ... ~57 more variants +} + +// Sub-enum for function names +pub enum IFunctionNameT<'a, 't> { + Function(&'t FunctionNameT<'a, 't>), + Forwarder(&'t ForwarderFunctionNameT<'a, 't>), + ExternFunction(&'t ExternFunctionNameT<'a, 't>), // also in IFunctionTemplateNameT + // ... +} + +// Sub-enum for function template names +pub enum IFunctionTemplateNameT<'a, 't> { + FunctionTemplate(&'t FunctionTemplateNameT<'a>), + ExternFunction(&'t ExternFunctionNameT<'a, 't>), // shared with IFunctionNameT + Forwarder(&'t ForwarderFunctionTemplateNameT<'a, 't>), + // ... +} + +// From impls for narrow → wide conversion +impl<'a, 't> From> for IInstantiationNameT<'a, 't> { ... } +impl<'a, 't> From> for INameT<'a, 't> { ... } +// TryFrom for wide → narrow (fallible) +impl<'a, 't> TryFrom> for IFunctionNameT<'a, 't> { ... } +``` + +### 4.3 `IdT` — Generic, Interned + +```rust +pub struct IdT<'a, 't, T> { + pub package_coord: &'a PackageCoordinate<'a>, + pub init_steps: &'t [&'t INameT<'a, 't>], + pub local_name: T, +} +``` + +`IdT` is interned in the `TypingInterner`. The generic parameter `T` preserves type-level knowledge of what kind of name is at the leaf (e.g., `IdT<'a, 't, &'t IFunctionNameT<'a, 't>>`). The `init_steps` is an arena-allocated slice of interned name references. `Hash`/`Eq` use pointer-based comparison on all interned components. + +### 4.4 `CoordT` and `KindT` + +```rust +pub struct CoordT<'a, 't> { + pub ownership: OwnershipT, + pub region: RegionT, + pub kind: &'t KindT<'a, 't>, +} + +pub enum KindT<'a, 't> { + Never(NeverT), + Void(VoidT), + Int(IntT), + Bool(BoolT), + Str(StrT), + Float(FloatT), + Struct(StructTT<'a, 't>), + Interface(InterfaceTT<'a, 't>), + StaticSizedArray(StaticSizedArrayTT<'a, 't>), + RuntimeSizedArray(RuntimeSizedArrayTT<'a, 't>), + KindPlaceholder(KindPlaceholderT<'a, 't>), + OverloadSet(OverloadSetT<'a, 't>), +} +``` + +All `KindT` variants are interned (including primitives, for uniformity). `CoordT` is interned. Both use pointer-based identity via `ptr_eq`. + +`OverloadSetT` holds `env: Rc>` — a special case. Its Val version holds the `Rc` for structural hashing. Interning uses pointer-based comparison on the `Rc` (via `Rc::as_ptr`) plus structural comparison on the name. + +### 4.5 `ITemplataT` — Type Parameter Erased + +Scala's `ITemplataT[+T <: ITemplataType]` becomes a plain enum with no type parameter: + +```rust +pub enum ITemplataT<'a, 't> { + Coord(&'t CoordTemplataT<'a, 't>), + Kind(&'t KindTemplataT<'a, 't>), + Placeholder(&'t PlaceholderTemplataT<'a, 't>), + Mutability(&'t MutabilityTemplataT), + Variability(&'t VariabilityTemplataT), + Ownership(&'t OwnershipTemplataT), + Integer(&'t IntegerTemplataT), + Boolean(&'t BooleanTemplataT), + String(&'t StringTemplataT<'a>), + Prototype(&'t PrototypeTemplataT<'a, 't>), + Isa(&'t IsaTemplataT<'a, 't>), + CoordList(&'t CoordListTemplataT<'a, 't>), + Function(&'t FunctionTemplataT<'a, 's, 't>), + StructDefinition(&'t StructDefinitionTemplataT<'a, 's, 't>), + InterfaceDefinition(&'t InterfaceDefinitionTemplataT<'a, 's, 't>), + ImplDefinition(&'t ImplDefinitionTemplataT<'a, 's, 't>), + RuntimeSizedArrayTemplate(&'t RuntimeSizedArrayTemplateTemplataT), + StaticSizedArrayTemplate(&'t StaticSizedArrayTemplateTemplataT), + ExternFunction(&'t ExternFunctionTemplataT<'a, 't>), +} +``` + +The Scala type parameter was informational — `PlaceholderTemplataT` already stores a runtime `tyype: ITemplataType` field, and `expect_*` methods do runtime matching. After erasure, struct fields that were `ITemplataT[MutabilityTemplataType]` become `&'t ITemplataT<'a, 't>`, losing compile-time narrowing but retaining runtime checks. + +`PrototypeTemplataT`'s own type parameter (`T <: IFunctionNameT`) is **orthogonal** to this erasure and can be decided independently. + +### 4.6 Mutual Recursion + +The type families are mutually recursive: + +``` +CoordT → KindT → StructTT → IdT → INameT → ITemplataT → CoordT +``` + +This compiles in Rust because every link in the chain goes through an `&'t` reference (pointer-sized, finite). No `Box` or `Vec` needed — the arena references provide the indirection. + +`ForwarderFunctionNameT.inner: &'t IFunctionNameT` and `ForwarderFunctionTemplateNameT.inner: &'t IFunctionTemplateNameT` — same-type recursion resolved by the `&'t` reference, no `Box` needed. + +--- + +## Part 5: Environments + +### 5.1 `Rc` for Long-Lived Storage + +Environments follow a strict **build-then-freeze** pattern: they are constructed mutably, then stored immutably and never modified after storage. The `Rc` wraps the **full** `IEnvironmentT` enum (not just `IInDenizenEnvironmentT`), because templata types use the broader `IEnvironmentT`: + +- `FunctionTemplataT.outer_env: Rc` +- `StructDefinitionTemplataT.declaring_env: Rc` +- `InterfaceDefinitionTemplataT.declaring_env: Rc` +- `ImplDefinitionTemplataT.env: Rc` + +`PackageEnvironmentT` is `IEnvironmentT` but not `IInDenizenEnvironmentT`, and top-level functions create `FunctionTemplataT(packageEnv, func)`. The `Rc` must encompass the full enum. + +```rust +pub enum IEnvironmentT<'a, 's, 't> { + Package(PackageEnvironmentT<'a, 's, 't>), + Citizen(CitizenEnvironmentT<'a, 's, 't>), + Function(FunctionEnvironmentT<'a, 's, 't>), + Node(NodeEnvironmentT<'a, 's, 't>), + BuildingWithClosureds(BuildingFunctionEnvironmentWithClosuredsT<'a, 's, 't>), + BuildingWithClosuredsAndTemplateArgs(BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT<'a, 's, 't>), + General(GeneralEnvironmentT<'a, 's, 't>), + Export(ExportEnvironmentT<'a, 's, 't>), + Extern(ExternEnvironmentT<'a, 's, 't>), +} +``` + +Parent chains use `Rc`: each environment holds `parent_env: Rc`. No circular references exist — parent chains are strictly tree-shaped (parent always created before child). + +`entryToTemplata` creates `FunctionTemplataT` on every lookup with `Rc::clone(defining_env)` — cheap (reference count bump). + +### 5.2 Mutable Environment Boxes (Stack-Local) + +During body compilation, mutable wrappers provide imperative mutation via functional update (replace the inner value with a new copy): + +```rust +struct NodeEnvironmentBox<'a, 's, 't> { + inner: NodeEnvironmentT<'a, 's, 't>, // owned, not Rc +} + +impl NodeEnvironmentBox<'a, 's, 't> { + fn add_variable(&mut self, new_var: ILocalVariableT<'a, 't>) { + self.inner = self.inner.add_variable(new_var); + } + + fn snapshot(&self) -> NodeEnvironmentT<'a, 's, 't> { + self.inner.clone() + } +} +``` + +Boxes are **never stored in `CompilerOutputs`** or templata values. They exist only as `&mut` parameters during expression compilation. The `snapshot()` method returns a clone that can be wrapped in `Rc` if needed for long-lived storage. + +For `if`-expression compilation, two child `NodeEnvironmentBox`es are created from the parent's snapshot, used independently for the then/else branches, then their effects are merged back into the parent. No aliased `&mut` — each child is an independent owned value. + +--- + +## Part 6: Expression AST + +### 6.1 Three Enums + +The expression AST uses three enums: + +```rust +// ~38 variants — expressions that produce a reference +pub enum ReferenceExpressionTE<'a, 't> { + LetNormal(LetNormalTE<'a, 't>), + If(IfTE<'a, 't>), + While(WhileTE<'a, 't>), + FunctionCall(FunctionCallTE<'a, 't>), + Consecutor(ConsecutorTE<'a, 't>), + Construct(ConstructTE<'a, 't>), + // ... +} + +// ~6 variants — expressions that produce an address (lvalue) +pub enum AddressExpressionTE<'a, 't> { + LocalLookup(LocalLookupTE<'a, 't>), + ReferenceMemberLookup(ReferenceMemberLookupTE<'a, 't>), + // ... +} + +// Wrapper — only needed for ConstructTE.args which mixes both +pub enum ExpressionTE<'a, 't> { + Reference(&'t ReferenceExpressionTE<'a, 't>), + Address(&'t AddressExpressionTE<'a, 't>), +} +``` + +`ConstructTE` is the **only** expression node that holds the broad `ExpressionTE` type (because closures can have addressible members). All other nodes hold either `&'t ReferenceExpressionTE` or `&'t AddressExpressionTE` specifically. + +### 6.2 Arena-Allocated, Not Interned + +Expression nodes are allocated into the `'t` arena but **not** interned (no deduplication). They are built once per compilation and form the function body trees. Sub-expression fields are `&'t ReferenceExpressionTE` or `&'t AddressExpressionTE` — arena references, no `Box`. + +Collection fields use arena slices: +- `ConsecutorTE.exprs: &'t [&'t ReferenceExpressionTE<'a, 't>]` +- `FunctionCallTE.args: &'t [&'t ReferenceExpressionTE<'a, 't>]` +- `ConstructTE.args: &'t [ExpressionTE<'a, 't>]` + +### 6.3 Visitor/Collector Pattern + +Following the established pattern from parsing and postparsing: + +1. A `NodeRefT<'a, 't>` enum with one variant per AST node type +2. `visit_*` functions for each node type that recurse into all child fields +3. `collect_in_*` entry points for traversal from a program/function/expression +4. `collect_where_tnodes!` / `collect_only_tnodes!` macros + +This is the same pattern used by `NodeRefP` (parsing) and `NodeRefS` (postparsing), defined in their respective `tests/traverse.rs` files. + +--- + +## Part 7: Error Handling + +### 7.1 `Result` With `?` + +Scala's `throw CompileErrorExceptionT(...)` becomes `return Err(CompileErrorT::...)` with `?` propagation throughout. The typing pass has a single catch boundary in Scala (`Compiler.evaluate()`); in Rust this becomes the `Result` return type of the top-level `evaluate()` method. + +Many functions that didn't return `Result` in Scala will need to in Rust, because their indirect callees return `Result`. This is expected and fine (see XRRIF principle). + +### 7.2 Panic for Unimplemented Code + +All unimplemented branches use `panic!()` with unique identifying messages (see XTUCMP principle). Functions that are entirely stubs are acceptable during incremental migration. + +--- + +## Part 8: Summary of Decisions + +| Decision | Choice | Rationale | +|----------|--------|-----------| +| Sub-compiler architecture | God struct with `&self` | Eliminates delegate traits; `&self` allows re-entrancy | +| Mutable state | `&mut CompilerOutputs` passed as parameter | Separates mutable state from immutable config | +| Typing pass arena | Separate `'t` arena, not the `'a` interner | Each pass owns its types with its own lifetime | +| Typing pass interning | `TypingInterner<'a, 't>` with own HashMaps | Same IDEPFL pattern, scoped to typing pass | +| Interned types | INameT, IdT, CoordT, KindT, ITemplataT, PrototypeT, SignatureT | All type-system values deduplicated for pointer identity | +| INameT hierarchy | Flat enums with sub-enums, From/TryFrom impls | Same pattern as postparsing, handles DAG via shared variants | +| ITemplataT type parameter | Erased — plain enum | Type parameter was informational; runtime `tyype` field preserved | +| IdT | Generic `IdT`, interned | Preserves type-level leaf knowledge; pointer-based Hash/Eq | +| Environments | `Rc` (full enum) | Build-then-freeze; no circular refs; cheap clone | +| Environment boxes | Owned mutable values, functional update | Stack-local, never stored long-lived | +| Expression AST | 3 enums (Ref + Addr + wrapper), arena-allocated, not interned | Output nodes, built once | +| Expression sub-expressions | `&'t` arena references, arena slices | No Box, no Vec | +| Deferred queues | VecDeque + HashSet, take-then-call | Avoids self-referential borrow | +| Macros | Receive god struct at call time | No stored sub-compiler references | +| Visitor/Collector | NodeRefT enum + visit_* functions + macros | Same pattern as parsing/postparsing | +| Error handling | `Result` with `?` | Replaces Scala exceptions | diff --git a/docs/historical/typing-pass-design-v2.md b/docs/historical/typing-pass-design-v2.md new file mode 100644 index 000000000..b0843a164 --- /dev/null +++ b/docs/historical/typing-pass-design-v2.md @@ -0,0 +1,786 @@ +# DO NOT FOLLOW — Historical, Obsolete (v2) + +> **This document is historical and obsolete.** It described a four-arena model (`'p, 's, 'e, 't`) with a separate env arena, generic `IdT<'t, T>`, interned `KindT` / `ITemplataT`, env-arena allocation, and IDs-not-refs in heavy templatas. **Every one of those decisions was reversed during Slabs 2–4.** +> +> The current authoritative design lives in **`TL-HANDOFF.md` at the repository root**.

Unchanged from existing codebase. +- **`'s` — Scout arena (`ScoutArena<'s>`)**: Postparser + higher-typing output (`FunctionA<'s>`, `StructA<'s>`, etc.), interned postparser names (`INameS<'s>`, `IRuneS<'s>`). Unchanged. +- **`'e` — Env arena (new, `EnvArena<'e>`)**: Typing-pass environments. Created at typing-pass start, dropped at pass end. All env instances arena-allocated; parent chains via `&'e` refs. +- **`'t` — Typing arena (new, `TypingInterner<'t>`)**: Interned typing-pass types (names, kinds, coords, templatas) and output AST (`FunctionDefinitionT`, expressions, etc.). **Created before the typing pass, outlives the typing pass.** Drops when the downstream consumer (instantiator) no longer needs its output. + +All four arenas use `bumpalo` (not bump-scope). Arena-allocated structs follow AASSNCMCX: no `Vec`/`HashMap`/`String` inside arena types; use arena slices and arena-backed sorted-pair maps instead. + +### 1.2 Lifetime Invariants + +1. **`'t` must outlive `'s, 'e, 'p`**: the typing arena is created first (in the call frame above the typing pass) and dropped last. Scout and env arenas die at pass end; only `'t` data survives. +2. **No `'t`-allocated type holds `&'s`, `&'p`, or `&'e` refs.** Cross-arena references from output into earlier arenas are never allowed. Any scout/parser data referenced from `'t` output must be **re-interned** into `'t` at the pass boundary. +3. **Working-state types (`CompilerOutputs`, `IEnvironmentT`) may hold `&'s`/`&'e` refs.** These types die at pass end, so their refs never dangle. +4. **`'t` is syntactically independent of `'s`, `'e`, `'p`.** No bound like `'t: 's` is declared, because `'t` must be free to outlive them. Rust's type system accepts this as long as no `'t`-typed value transitively contains a `'s`/`'e`/`'p` ref. +5. **Re-interning at the `'s → 't` boundary** is mandatory for: `StrI`, package/file coordinates, `RangeS`, `CodeLocationS`, `IImpreciseNameS`, any other scout-lifetime data that appears in typing output. + +### 1.3 Arena Construction Order + +```rust +fn run_typing_pass<'p, 's, 't>( + parse_arena: &ParseArena<'p>, + scout_arena: &ScoutArena<'s>, + typing_interner: &'t TypingInterner<'t>, // created by caller, outlives pass + program_a: &'s ProgramA<'s>, +) -> HinputsT<'t> { + let env_arena = EnvArena::new(); // 'e begins here + let compiler = Compiler::new(parse_arena, scout_arena, &env_arena, typing_interner, ...); + let hinputs = compiler.compile(program_a); + hinputs // HinputsT<'t>, free of 's/'e/'p refs + // env_arena drops here → 'e gone + // caller may drop scout_arena, parse_arena → 's, 'p gone +} +``` + +### 1.4 Where Each Type Lives + +| Type | Lifetimes | Arena | +|---|---|---| +| `HinputsT` | `<'t>` | typing arena, survives pass | +| `FunctionDefinitionT`, `StructDefinitionT`, `InterfaceDefinitionT`, `ImplT`, `EdgeT` | `<'t>` | typing arena | +| `KindT`, `CoordT`, `IdT`, `INameT` | `<'t>` | typing arena, interned | +| `ITemplataT` (all variants, leaf and heavy) | `<'t>` | typing arena | +| `ReferenceExpressionTE`, `AddressExpressionTE` | `<'t>` | typing arena, not interned | +| `IEnvironmentT` and sub-types | `<'s, 'e, 't>` | env arena, references scout data | +| `CompilerOutputs` | `<'s, 'e, 't>` | stack; dies at pass end | +| `Compiler` (god struct) | `<'s, 'ctx, 'e, 't>` | stack; dies at pass end | + +--- + +## Part 2: The God Struct + +### 2.1 Architecture + +All Scala sub-compilers (`FunctionCompiler`, `ExpressionCompiler`, `StructCompiler`, `ImplCompiler`, `OverloadResolver`, `InferCompiler`, `TemplataCompiler`, `ConvertHelper`, `DestructorCompiler`, `VirtualCompiler`, `SequenceCompiler`, `ArrayCompiler`, `EdgeCompiler`, `BlockCompiler`, `PatternCompiler`, `CallCompiler`, `LocalHelper`) collapse into methods on a single `Compiler` struct. + +```rust +pub struct Compiler<'s, 'ctx, 'e, 't> { + pub typing_interner: &'ctx TypingInterner<'t>, + pub scout_arena: &'ctx ScoutArena<'s>, + pub env_arena: &'ctx EnvArena<'e>, + pub keywords: &'ctx Keywords<'t>, // re-interned into 't + pub opts: &'ctx TypingPassOptions, + pub global_env: Rc>, // top-level env, arena-allocated + pub name_translator: NameTranslator, +} +``` + +The god struct holds only **immutable configuration**. All mutable state is passed as `&mut` parameters, primarily `&mut CompilerOutputs<'s, 'e, 't>`. + +### 2.2 Why `&self` + `&mut coutputs` Works + +Deep mutual recursion (e.g. `evaluate_expression → evaluate_prefix_call → find_function → evaluate_function_body → evaluate_expression`) requires re-entrant access. With `&mut self`, this would require two simultaneous mutable borrows of the god struct. With `&self` (immutable config) plus `&mut coutputs`, re-entrancy is fine — multiple immutable borrows of `self` are allowed. + +### 2.3 Macros + +Macros (`AsSubtypeMacro`, `LockWeakMacro`, `StructDropMacro`, etc.) are stored in the global environment and receive the god struct at call time: + +```rust +trait IFunctionGenerator<'s, 'e, 't> { + fn generate( + &self, + compiler: &Compiler<'s, '_, 'e, 't>, + coutputs: &mut CompilerOutputs<'s, 'e, 't>, + env: &'e IEnvironmentT<'s, 'e, 't>, + // ... + ) -> &'t FunctionHeaderT<'t>; +} +``` + +`AsSubtypeMacro` (and similar macros with multiple dispatch paths) becomes an enum with one variant per kind, rather than a trait-object hierarchy. + +### 2.4 Delegate Traits Eliminated + +In Scala, sub-compilers were wired via anonymous delegate traits (`IExpressionCompilerDelegate`, `IFunctionCompilerDelegate`, etc.). With the god struct, these are unnecessary — every method is on the same struct and directly accessible via `self.method_name(...)`. + +--- + +## Part 3: Environments + +### 3.1 Arena-Allocated, Not Refcounted + +Environments live in the `'e` arena. Parent chains use `&'e` references: + +```rust +pub enum IEnvironmentT<'s, 'e, 't> { + Package(PackageEnvironmentT<'s, 'e, 't>), + Citizen(CitizenEnvironmentT<'s, 'e, 't>), + Function(FunctionEnvironmentT<'s, 'e, 't>), + Node(NodeEnvironmentT<'s, 'e, 't>), + BuildingWithClosureds(BuildingFunctionEnvironmentWithClosuredsT<'s, 'e, 't>), + BuildingWithClosuredsAndTemplateArgs(BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT<'s, 'e, 't>), + General(GeneralEnvironmentT<'s, 'e, 't>), + Export(ExportEnvironmentT<'s, 'e, 't>), + Extern(ExternEnvironmentT<'s, 'e, 't>), +} + +pub struct NodeEnvironmentT<'s, 'e, 't> { + pub parent: &'e IEnvironmentT<'s, 'e, 't>, + pub parent_function_env: &'e FunctionEnvironmentT<'s, 'e, 't>, + pub life: LocationInFunctionEnvT<'t>, + pub templatas: TemplatasStoreT<'t>, // arena-backed sorted Vec-pair, not HashMap + pub declared_locals: &'e [&'e ILocalVariableT<'t>], + pub templata_id: OnceCell<&'t IdT<'t>>, // cached FunctionTemplata id (see §3.5) + // ... +} +``` + +The bound `'t: 'e` is **not declared**. Env types transitively hold `&'t` refs (via templatas), but since `'t` outlives `'e` in all call frames that construct envs, this works without an explicit bound. If rustc requires it in practice, `'t: 'e` is safe to add. + +### 3.2 `TemplatasStoreT` Uses Arena-Backed Sorted Pairs + +Scala's `TemplatasStore` uses `Map[INameT, IEnvEntry]`. In Rust we **must not** use `HashMap`/`IndexMap` inside arena types: bumpalo doesn't run destructors (AASSNCMCX), and heap-backed HashMaps at 1M+ envs would blow memory. Instead: + +```rust +pub struct TemplatasStoreT<'t> { + pub name_to_entry: &'t [(INameT<'t>, IEnvEntryT<'t>)], // sorted by name ptr + pub imprecise_to_entries: &'t [(IImpreciseNameT<'t>, &'t [IEnvEntryT<'t>])], + pub id: &'t IdT<'t>, // the template id this store is associated with (parent-function id) +} +``` + +Sorted by interned pointer address → binary search is O(log N). Most scopes have <10 entries, where linear scan of a `Vec`-pair slice is faster than HashMap anyway. No `Drop`, no heap backing. + +### 3.3 Mutable Building Phase + +During construction, an env is mutable — e.g., adding variables/locals/templatas as a block is compiled: + +```rust +pub struct NodeEnvironmentBuilder<'s, 'e, 't> { + pub parent: &'e IEnvironmentT<'s, 'e, 't>, + pub parent_function_env: &'e FunctionEnvironmentT<'s, 'e, 't>, + pub life: LocationInFunctionEnvT<'t>, + pub templatas_pending: Vec<(INameT<'t>, IEnvEntryT<'t>)>, // heap Vec, OK on stack + pub declared_locals_pending: Vec<&'e ILocalVariableT<'t>>, + // ... +} + +impl<'s, 'e, 't> NodeEnvironmentBuilder<'s, 'e, 't> { + pub fn build_in(self, env_arena: &'e EnvArena<'e>) -> &'e NodeEnvironmentT<'s, 'e, 't> { + // Sort the pending entries, copy into arena slices, construct the final env, + // allocate into arena, return &'e ref. + env_arena.alloc(NodeEnvironmentT { + parent: self.parent, + // ... freeze self.templatas_pending into &'t [...] via typing_interner + // ... etc + }) + } +} +``` + +Mutable builders live on the stack with heap `Vec`s. When finalized, entries are sorted and copied into arena slices, and the final immutable env is placed in `'e`. + +### 3.4 `&'e` vs `&IEnvironmentT` — Storage vs Read + +Scala's `NodeEnvironmentBox.snapshot: NodeEnvironmentT` is called ~36 times in ExpressionCompiler.scala — many for **transient reads** (passing to `isTypeConvertible`, parent traversals, etc.), not just for long-term storage. + +In Rust, we distinguish: +- **`&IEnvironmentT<'_, 'e, 't>`** (elided lifetime) — read-only borrow, transient, zero cost, used for helpers that just inspect the env. +- **`&'e IEnvironmentT<'s, 'e, 't>`** — arena-pinned reference, needed when storing into a side table, output type, or parent pointer. + +`&'e` promotion via arena allocation happens only at explicit "store this env" points. Transient reads use `&` and Rust's lifetime elision handles the rest. + +### 3.5 `FunctionTemplata` ID Caching On Envs + +Scala's `FunctionEnvironmentT` has `def templata = FunctionTemplataT(parentEnv, this.function)` — produces a fresh instance on every call. In Rust with ID-based side tables, we cache the ID: + +```rust +pub struct FunctionEnvironmentT<'s, 'e, 't> { + // ... + pub templata_id: OnceCell<&'t IdT<'t>>, +} + +impl<'s, 'e, 't> FunctionEnvironmentT<'s, 'e, 't> { + pub fn templata_id( + &self, + compiler: &Compiler<'s, '_, 'e, 't>, + coutputs: &mut CompilerOutputs<'s, 'e, 't>, + ) -> &'t IdT<'t> { + *self.templata_id.get_or_init(|| { + let id = compiler.typing_interner.intern_id(/* ...templata id... */); + coutputs.origin_function_a.insert(id, self.function); + coutputs.origin_env.insert(id, compiler.env_arena.alloc(self.clone())); + id + }) + } +} +``` + +First access allocates; subsequent accesses return the cached ID. + +### 3.6 Env-ID Uniqueness Is NOT Required + +Environments in Rust do not need unique `id` fields per live instance. Scala allows collisions (`NodeEnvironmentT.id = parent_function_env.id`; GeneralEnvironmentT reuses caller ids; Box wrappers share ids with wrapped envs). Rust does not key any HashMap on env's own `id` field: + +- `CompilerOutputs.function_name_to_outer_env` etc. are keyed by **function/type template ids** (which are genuinely unique), not env's own id. +- OverloadSet env lookup uses `ctx_id` (synthetic, allocated fresh per OverloadSet construction), not env id. +- Heavy templata side tables use IDs minted at templata construction, not env id. + +Env `id` is used only for diagnostics, for child template-store tagging, and matching Scala's semantics on equality (which Rust doesn't replicate since we never hash envs). + +### 3.7 Env Arena Global To Compiler + +The `'e` arena lives on the `Compiler` god struct, constructed at typing-pass start, accessible from every compilation method. It is **not** per-denizen or per-function. Required because: + +- Closures construct envs that need `'e` allocation at the moment `FunctionTemplataT` is built (from scattered sites like `StructCompilerCore.scala:374`, `AbstractBodyMacro.scala:37`). +- Envs reference each other via parent chains that cross denizen boundaries. + +Memory-wise this is equivalent to Scala's GC approach — envs live until pass end regardless. + +--- + +## Part 4: CompilerOutputs + +### 4.1 Structure + +`CompilerOutputs` is the mutable accumulator threaded through the entire pass. It carries `<'s, 'e, 't>` because it holds side tables referencing scout and env data: + +```rust +pub struct CompilerOutputs<'s, 'e, 't> { + // Function registries (all keys are 't-interned ids) + pub return_types_by_signature: HashMap>, CoordT<'t>>, + pub signature_to_function: HashMap>, &'t FunctionDefinitionT<'t>>, + + // Declaration tracking + pub function_declared_names: HashMap>, RangeT<'t>>, + pub type_declared_names: HashSet>>, + + // Env storage, keyed by function/type template id (per Scala parity) + pub function_name_to_outer_env: HashMap>, &'e IEnvironmentT<'s, 'e, 't>>, + pub function_name_to_inner_env: HashMap>, &'e IEnvironmentT<'s, 'e, 't>>, + pub type_name_to_outer_env: HashMap>, &'e IEnvironmentT<'s, 'e, 't>>, + pub type_name_to_inner_env: HashMap>, &'e IEnvironmentT<'s, 'e, 't>>, + + // Side tables: 't-id → 's scout data (die at pass end) + pub origin_function_a: HashMap>, &'s FunctionA<'s>>, + pub origin_struct_a: HashMap>, &'s StructA<'s>>, + pub origin_interface_a: HashMap>, &'s InterfaceA<'s>>, + pub origin_impl_a: HashMap>, &'s ImplA<'s>>, + pub origin_env: HashMap>, &'e IEnvironmentT<'s, 'e, 't>>, + + // OverloadSet env lookup (see §5) + pub overload_resolution_ctx: HashMap>, &'e IEnvironmentT<'s, 'e, 't>>, + + // Definitions, impls, exports, externs — all 't-only + pub struct_template_name_to_definition: HashMap>, &'t StructDefinitionT<'t>>, + pub interface_template_name_to_definition: HashMap>, &'t InterfaceDefinitionT<'t>>, + pub all_impls: HashMap>, &'t ImplT<'t>>, + pub sub_citizen_template_to_impls: HashMap>, &'t [&'t ImplT<'t>]>, + pub super_interface_template_to_impls: HashMap>, &'t [&'t ImplT<'t>]>, + pub kind_exports: Vec<&'t KindExportT<'t>>, + pub function_exports: Vec<&'t FunctionExportT<'t>>, + pub kind_externs: Vec<&'t KindExternT<'t>>, + pub function_externs: Vec<&'t FunctionExternT<'t>>, + pub instantiation_name_to_bounds: HashMap>, &'t InstantiationBoundArgumentsT<'t>>, + + // Deferred evaluation queues (see §4.4) + pub deferred_actions: VecDeque>, + pub finished_deferred_function_body_compiles: HashSet>>, + pub finished_deferred_function_compiles: HashSet>>, +} +``` + +### 4.2 `PtrKey<'t, T>` Newtype For HashMap Keys + +Interned `&'t T` refs hash by pointer identity, not structural equality. This is correctness-critical (pointer-eq ⇔ value-eq given correct interning) and fast (O(1) hash). + +```rust +pub struct PtrKey<'t, T: ?Sized>(pub &'t T); + +impl<'t, T: ?Sized> PartialEq for PtrKey<'t, T> { + fn eq(&self, other: &Self) -> bool { std::ptr::eq(self.0, other.0) } +} +impl<'t, T: ?Sized> Eq for PtrKey<'t, T> {} +impl<'t, T: ?Sized> Hash for PtrKey<'t, T> { + fn hash(&self, state: &mut H) { (self.0 as *const T as *const ()).hash(state) } +} +impl<'t, T: ?Sized> Copy for PtrKey<'t, T> {} +impl<'t, T: ?Sized> Clone for PtrKey<'t, T> { fn clone(&self) -> Self { *self } } +``` + +### 4.3 Side-Table Access Pattern — Copy Out Before &mut + +A common operation is "look up something by id, then use it while continuing to mutate `coutputs`." The naïve pattern fails the borrow checker: + +```rust +// DOES NOT COMPILE: +let env = coutputs.overload_resolution_ctx.get(&PtrKey(ctx_id)).unwrap(); +self.resolve_with_env(coutputs, *env, ...); // &mut coutputs rejected; env borrows from it +``` + +**Invariant: all side-table values are pointer-sized `Copy` types (`&'s T`, `&'e T`, `&'t T` refs).** Copy out first: + +```rust +let env: &'e IEnvironmentT<'s, 'e, 't> = *coutputs.overload_resolution_ctx.get(&PtrKey(ctx_id)).unwrap(); +// env is now an independent ref; coutputs is no longer borrowed. +self.resolve_with_env(coutputs, env, ...); // OK +``` + +If any side-table value were an owned struct or `Vec`, this pattern would fail. Enforce at review time: side-table values are always `&'_ Something` or equivalent `Copy`. + +### 4.4 Deferred Actions + +Scala uses closures in `LinkedHashMap` for deferred evaluation. Rust avoids `Box` by using a structured enum: + +```rust +pub enum DeferredActionT<'s, 'e, 't> { + EvaluateFunctionBody { + prototype: &'t PrototypeT<'t>, + function_env: &'e FunctionEnvironmentT<'s, 'e, 't>, + origin: &'s FunctionA<'s>, + }, + EvaluateFunction { + name: &'t IdT<'t>, + calling_env: &'e IEnvironmentT<'s, 'e, 't>, + origin: &'s FunctionA<'s>, + template_args: &'t [&'t ITemplataT<'t>], + }, + // Add variants for additional deferred work kinds as needed. +} +``` + +Drain loop matches on the variant: + +```rust +while let Some(action) = coutputs.deferred_actions.pop_front() { + match action { + DeferredActionT::EvaluateFunctionBody { prototype, function_env, origin } => { + self.evaluate_function_body(coutputs, prototype, function_env, origin); + coutputs.finished_deferred_function_body_compiles.insert(PtrKey(prototype)); + } + DeferredActionT::EvaluateFunction { name, calling_env, origin, template_args } => { + self.evaluate_function(coutputs, name, calling_env, origin, template_args); + coutputs.finished_deferred_function_compiles.insert(PtrKey(name)); + } + } +} +``` + +No `Box`, no `dyn`, no hidden captures. Every input is spelled out in the variant; debugging is easier; closures' lifetime-capture subtleties never arise. + +### 4.5 Speculative Writes Are Idempotent + +During overload resolution, `attempt_candidate_banner` writes to `coutputs` (e.g., `add_instantiation_bounds`) even for candidates that may later be rejected. This is safe because all writes are **idempotent** — re-writing the same value asserts equality (`assert_eq!(existing, new)`). No rollback mechanism is needed. + +--- + +## Part 5: OverloadSet + +### 5.1 Transient Type, Vestigial In Output + +Per Agent F's investigation: + +- **OverloadSet resolution always completes during the typing pass.** No unresolved OverloadSet ever flows into the instantiator. +- **But** an `OverloadSet`-kinded `ReinterpretTE(VoidLiteralTE, ...)` survives in `FunctionDefinitionT.body` as an inert type tag on argument expressions (the instantiator elides these, using `InstantiationBoundArgumentsT.runeToFunctionBoundArg` to find the real prototype). + +So `OverloadSetT` must be a valid `KindT<'t>` variant in output, but its content is consumed only during the typing pass. + +### 5.2 `OverloadSetT<'t>` — Name + Context ID + +```rust +pub struct OverloadSetT<'t> { + pub name: &'t IImpreciseNameT<'t>, // re-interned from 's + pub ctx_id: &'t OverloadResolutionCtxIdT<'t>, +} + +pub struct OverloadResolutionCtxIdT<'t> { + pub disambiguator: u64, // unique per construction + pub _marker: PhantomData<&'t ()>, +} +``` + +Each `OverloadSetT` carries a unique `ctx_id` allocated fresh at construction. During the pass, `CompilerOutputs.overload_resolution_ctx` maps `ctx_id → &'e IEnvironmentT<'s, 'e, 't>`, giving the overload resolver access to the env. + +### 5.3 Construction + +```rust +impl<'s, 'ctx, 'e, 't> Compiler<'s, 'ctx, 'e, 't> { + pub fn make_overload_set_kind( + &self, + coutputs: &mut CompilerOutputs<'s, 'e, 't>, + env: &'e IEnvironmentT<'s, 'e, 't>, + name_s: &'s IImpreciseNameS<'s>, + ) -> &'t KindT<'t> { + let name_t = self.typing_interner.intern_imprecise_name(/* re-intern name_s into 't */); + let ctx_id = self.typing_interner.alloc_fresh_overload_ctx(); + coutputs.overload_resolution_ctx.insert(PtrKey(ctx_id), env); + self.typing_interner.intern_kind(KindValT::OverloadSet(OverloadSetT { name: name_t, ctx_id })) + } +} +``` + +### 5.4 Why Filtered Candidates Don't Work + +Earlier consideration: bake the candidate list into `OverloadSetT` at construction time. Agent G confirmed this is insufficient — the resolver uses the env for **5+ purposes beyond "find candidates"**: + +1. `RuneParentEnvLookupSR` resolution +2. Rune-type solver context +3. `InferCompiler.solveForResolving` (templata lookup, isDescendant, placeholder root-env checks) +4. `isTypeConvertible` +5. Generic function evaluation (CSSNCE — "callee needs to see functions declared here") +6. Nested-OverloadSet recursion + +Filtered candidates would need to re-resolve against these at a later point; the env itself is the minimum sufficient context. Hence ctx_id + side table. + +### 5.5 Overload Resolution Threads `&CompilerOutputs` + +Scala's `getCandidateBannersInner` reads `overloadSet.env` directly. In Rust it must thread `&CompilerOutputs` (or more generally, `&self` of the god struct + `&mut coutputs`) so that the ctx_id can resolve to an env. This changes the Scala signature, but it's consistent with the god-struct pattern where every compilation method takes `&mut coutputs`. + +### 5.6 Post-Pass Behavior + +After the typing pass completes: +- `CompilerOutputs` drops, including `overload_resolution_ctx`. +- Any `OverloadSetT` in `HinputsT` has a `ctx_id` that no longer resolves. +- Nothing downstream dereferences `ctx_id` — the instantiator uses `InstantiationBoundArgumentsT` instead. + +--- + +## Part 6: Type System Types + +### 6.1 IDEPFL Dual-Enum Pattern + +All interned typing types use the dual-enum pattern: a **reference enum** (canonical, `&'t` refs) and a **value enum** (transient, for HashMap lookup). Scout/postparser re-interning produces `IImpreciseNameT<'t>`, `StrI<'t>`, `RangeT<'t>`, etc. + +Interned type families: +- `INameT<'t>` / `INameValT<'t>` (~60 variants) +- `IdT<'t, T>` / `IdValT<'t, T>` (generic, see §6.3) +- `CoordT<'t>` — **inline Copy, not interned** (see §6.4) +- `KindT<'t>` / `KindValT<'t>` +- `ITemplataT<'t>` / `ITemplataValT<'t>` +- `PrototypeT<'t>` / `PrototypeValT<'t>` +- `SignatureT<'t>` / `SignatureValT<'t>` +- `StrI<'t>`, `IImpreciseNameT<'t>`, `RangeT<'t>`, `CodeLocationT<'t>`, `PackageCoordinateT<'t>`, `FileCoordinateT<'t>` + +### 6.2 INameT Hierarchy + +~60 concrete name types, organized into ~14 sub-trait enums. Shared DAG variants (types that appear under multiple sub-traits) get variants in each relevant sub-enum. `From` for narrow→wide, `TryFrom` for wide→narrow. + +New name variants (not in v1) needed for the env-arena design: +- **(optional)** `NodeNameT { function_id, life }` if we later want env-id uniqueness. Current design does not require it. + +### 6.3 `IdT<'t, T>` — Generic, Interned + +```rust +pub struct IdT<'t, T: Into<&'t INameT<'t>> + Copy> { + pub package_coord: &'t PackageCoordinateT<'t>, + pub init_steps: &'t [&'t INameT<'t>], + pub local_name: T, +} +``` + +Generic parameter preserves leaf-kind info at the type level. Cast methods widen/narrow: + +```rust +impl<'t, T: Into<&'t INameT<'t>> + Copy> IdT<'t, T> { + pub fn widen(self) -> IdT<'t, &'t INameT<'t>> { ... } + pub fn widen_to> + Copy>(self) -> IdT<'t, U> + where T: Into { ... } +} + +impl<'t> IdT<'t, &'t INameT<'t>> { + pub fn try_narrow(self) -> Option> + where &'t INameT<'t>: TryInto { ... } +} +``` + +Rust can't replicate Scala's covariance (`IdT[+T <: INameT]`); explicit casts are required. Interning uses a single HashMap keyed by `IdValT<'t, &'t INameT<'t>>` (widest form); narrowing happens on the way out. + +### 6.4 `CoordT<'t>` — Inline Copy + +`CoordT` is small (3 fields, all Copy or pointer-sized). We make it `Copy + Clone` and pass by value rather than interning: + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub struct CoordT<'t> { + pub ownership: OwnershipT, + pub region: RegionT, + pub kind: &'t KindT<'t>, // interned +} +``` + +Equality uses structural eq (ownership + region + ptr-eq on kind). Hash combines all three fields. Appears by value in every expression node — no arena allocation per coord, 24 bytes inline. + +### 6.5 `KindT<'t>` — Interned + +```rust +pub enum KindT<'t> { + Never, + Void, + Int(IntT), // small, Copy + Bool, + Str, + Float, + Struct(StructTT<'t>), + Interface(InterfaceTT<'t>), + StaticSizedArray(StaticSizedArrayTT<'t>), + RuntimeSizedArray(RuntimeSizedArrayTT<'t>), + KindPlaceholder(KindPlaceholderT<'t>), + OverloadSet(&'t OverloadSetT<'t>), // see §5 +} +``` + +All variants interned. Pointer-eq on `&'t KindT` is identity. + +### 6.6 `ITemplataT<'t>` — Type Parameter Erased, Split Into Leaf/Heavy + +Scala's `ITemplataT[+T <: ITemplataType]` becomes a plain enum with no type parameter (type info preserved in a runtime `tyype` field on `PlaceholderTemplataT`): + +```rust +pub enum ITemplataT<'t> { + // Leaf templatas — appear freely in template arg slots in output + Coord(&'t CoordTemplataT<'t>), + Kind(&'t KindTemplataT<'t>), + Placeholder(&'t PlaceholderTemplataT<'t>), + Mutability(MutabilityTemplataT), + Variability(VariabilityTemplataT), + Ownership(OwnershipTemplataT), + Integer(i64), + Boolean(bool), + String(&'t StrI<'t>), + Prototype(&'t PrototypeTemplataT<'t>), + Isa(&'t IsaTemplataT<'t>), + CoordList(&'t CoordListTemplataT<'t>), + RuntimeSizedArrayTemplate(RuntimeSizedArrayTemplateTemplataT), + StaticSizedArrayTemplate(StaticSizedArrayTemplateTemplataT), + + // Heavy templatas — appear in envs and 3 specific named output slots + Function(&'t FunctionTemplataT<'t>), + StructDefinition(&'t StructDefinitionTemplataT<'t>), + InterfaceDefinition(&'t InterfaceDefinitionTemplataT<'t>), + ImplDefinition(&'t ImplDefinitionTemplataT<'t>), + ExternFunction(&'t ExternFunctionTemplataT<'t>), +} +``` + +Heavy templatas hold IDs, not scout refs: + +```rust +pub struct FunctionTemplataT<'t> { + pub outer_env_id: &'t IdT<'t>, // look up env in coutputs.origin_env + pub origin_id: &'t IdT<'t>, // look up FunctionA in coutputs.origin_function_a + // Any summary data needed without a side-table lookup is copied inline: + pub name: &'t IFunctionDeclarationNameT<'t>, +} + +pub struct StructDefinitionTemplataT<'t> { + pub declaring_env_id: &'t IdT<'t>, + pub origin_id: &'t IdT<'t>, // look up StructA + pub name: &'t IStructDeclarationNameT<'t>, +} + +pub struct InterfaceDefinitionTemplataT<'t> { /* similar */ } +pub struct ImplDefinitionTemplataT<'t> { /* similar */ } +pub struct ExternFunctionTemplataT<'t> { /* holds an &'t FunctionHeaderT */ } +``` + +Constraint (by convention, enforced at construction sites): +- **Template-arg slots** (`IdT.init_steps`, `IInstantiationNameT.templateArgs`, etc.) hold only leaf templata variants. +- **Heavy templatas** appear only in: (a) envs' `TemplatasStore`, (b) `ImplT.templata`, (c) `FunctionHeaderT.maybe_origin_function_templata`, (d) `FunctionBannerT.origin_function_templata`. + +### 6.7 Mutual Recursion + +Types form a mutually recursive graph (`CoordT → KindT → StructTT → IdT → INameT → ITemplataT → CoordT`). Compiles because every link is a `&'t` ref — pointer-sized, finite. No `Box`/`Vec` needed; arena references provide the indirection. + +--- + +## Part 7: Expression AST + +### 7.1 Three Enums + +```rust +pub enum ReferenceExpressionTE<'t> { + LetNormal(LetNormalTE<'t>), + If(IfTE<'t>), + While(WhileTE<'t>), + FunctionCall(FunctionCallTE<'t>), + Consecutor(ConsecutorTE<'t>), + Construct(ConstructTE<'t>), + Reinterpret(ReinterpretTE<'t>), // includes the OverloadSet-tag case + // ... ~30 more variants +} + +pub enum AddressExpressionTE<'t> { + LocalLookup(LocalLookupTE<'t>), + ReferenceMemberLookup(ReferenceMemberLookupTE<'t>), + // ... ~4 more +} + +pub enum ExpressionTE<'t> { + Reference(&'t ReferenceExpressionTE<'t>), + Address(&'t AddressExpressionTE<'t>), +} +``` + +Used when a slot can hold either (e.g. `ConstructTE.args` because closures can have addressable members). All other slots are specifically `&'t ReferenceExpressionTE` or `&'t AddressExpressionTE`. + +### 7.2 Arena-Allocated, Not Interned + +Expression nodes allocate into `'t` but don't dedupe (no HashMap lookup on construction). Each compiled expression is constructed once. Sub-expression fields are `&'t` refs; collections are arena slices. + +### 7.3 Pure `<'t>`, Always + +Every TE field is pure `'t`. No `'s`/`'e` leak. The OverloadSet case is handled by `OverloadSetT<'t>` (§5) carrying a `ctx_id` — no direct env reference in the TE. + +### 7.4 Visitor/Collector Pattern + +Following the established pattern from parsing and postparsing: a `NodeRefT<'t>` enum with one variant per AST node type, `visit_*` functions per node, entry points for traversal, and `collect_where_tnodes!`/`collect_only_tnodes!` macros. + +--- + +## Part 8: Error Handling + +### 8.1 `Result` With `?` + +Scala's `throw CompileErrorExceptionT(...)` becomes `return Err(CompileErrorT::...)` with `?` propagation. Single catch boundary at the top-level `Compiler::compile()`. + +### 8.2 Panic For Unimplemented + +Unimplemented branches use `panic!()` with unique identifying messages. Functions that are fully-stub during incremental migration are acceptable. + +--- + +## Part 9: Keywords + +### 9.1 `Keywords<'t>` + +`Keywords` holds interned strings used throughout the pass. Since scout-lifetime `StrI<'s>` can't appear in `'t` output, the typing pass uses `Keywords<'t>` with strings re-interned from whichever source. Created once at pass start (or provided by caller). + +If the instantiator needs Keywords with its own arena lifetime, it creates a fresh `Keywords<'inst>`. Keywords is cheap to re-create. + +--- + +## Part 10: Driving The Pass + +### 10.1 Top-Level Entry + +```rust +pub fn run_typing_pass<'p, 's, 't>( + parse_arena: &ParseArena<'p>, + scout_arena: &ScoutArena<'s>, + typing_interner: &'t TypingInterner<'t>, + keywords: &Keywords<'t>, + opts: &TypingPassOptions, + program_a: &'s ProgramA<'s>, +) -> Result, CompileErrorT<'t>> { + let env_arena = EnvArena::new(); // 'e + let compiler = Compiler::new( + parse_arena, scout_arena, &env_arena, typing_interner, keywords, opts, + ); + + let mut coutputs = CompilerOutputs::new(); + compiler.compile_program(&mut coutputs, program_a)?; + + // Drain deferred actions to completion. + compiler.drain_all_deferred(&mut coutputs); + + // Extract pure-'t output. + let hinputs = HinputsT { + function_definitions: typing_interner.alloc_slice_iter( + coutputs.signature_to_function.into_values() + ), + struct_definitions: typing_interner.alloc_slice_iter( + coutputs.struct_template_name_to_definition.into_values() + ), + interface_definitions: ..., + edges: ..., + kind_exports: typing_interner.alloc_slice_from_vec(coutputs.kind_exports), + function_exports: typing_interner.alloc_slice_from_vec(coutputs.function_exports), + // ... + }; + + Ok(hinputs) + // coutputs drops here → side tables die → &'s/&'e refs released + // env_arena drops here → 'e done + // caller drops scout_arena, parse_arena → 's, 'p done + // typing_interner outlives this function; HinputsT<'t> flows downstream +} +``` + +No explicit `finalize()` method. The extraction is just the natural end of the function; `coutputs` drop happens implicitly at scope exit. + +### 10.2 Instantiator Handoff + +The instantiator receives `HinputsT<'t>` plus a reference to the typing interner (for further lookups if needed). It does not receive the scout arena, env arena, parser arena, or CompilerOutputs — all are dead. It works purely from `'t` data. + +--- + +## Part 11: Invariants Summary + +For quick review during implementation: + +1. **No `'t`-allocated struct holds `&'s`, `&'e`, or `&'p` refs.** If you see a field with an `'s` lifetime inside a `'t`-lifetime struct, that's a bug. +2. **All side-table values are pointer-sized `Copy` refs** (`&'s T`, `&'e T`, `&'t T`). No owned structs or `Vec`s as side-table values. +3. **All HashMap keys on interned refs use `PtrKey<'t, T>`**, never raw `&T` with derived `Hash`/`Eq`. +4. **Arena types never contain `Vec`, `HashMap`, `String`, `Rc`, `Box`.** Use arena slices and sorted Vec-pair maps. (Matches existing AASSNCMCX shield.) +5. **`'e` arena is global to `Compiler`**, not per-denizen. Env construction sites must have arena access. +6. **Re-intern scout data (`StrI`, names, ranges, coords) into `'t` at the `'s → 't` boundary.** Never carry `&'s` data into output. +7. **Side-table access: always copy out the Copy ref before continuing to mutate `coutputs`.** +8. **`'t` is lifetime-independent of `'s`, `'e`, `'p`.** No `'t: 's` bounds declared. +9. **Heavy templatas hold IDs, not scout refs.** Lookup via `CompilerOutputs` side tables during the pass. +10. **Overload resolution always completes during the typing pass.** No unresolved overloads reach the instantiator. +11. **Env equality/hashing never used.** `CompilerOutputs` never keys envs by their `.id`; keys are function/type template ids. + +--- + +## Part 12: Slab-Ordered Migration Plan + +Implementation proceeds bottom-up through dependency slabs. Each slab produces a compiling sub-layer. + +1. **Slab 0**: Arena substrate — `TypingInterner<'t>`, `EnvArena<'e>`, new lifetime conventions. +2. **Slab 1**: Leaf types — `OwnershipT`, `MutabilityT`, `VariabilityT`, `LocationT`, `RegionT`, primitive `KindT` payloads, leaf templata types. +3. **Slab 2**: Re-intern boundary — `StrI<'t>`, `PackageCoordinateT<'t>`, `FileCoordinateT<'t>`, `RangeT<'t>`, `CodeLocationT<'t>`, `IImpreciseNameT<'t>`. +4. **Slab 3**: Name hierarchy — all ~60 `INameT` variants, `IdT<'t, T>` with casts, sub-enums, `INameValT` companions. +5. **Slab 4**: Kind/Coord/Templata trio — non-primitive `KindT` variants, `CoordT<'t>` inline, `ITemplataT<'t>` (leaf + heavy), `PrototypeT`, `SignatureT`, `OverloadSetT`, `OverloadResolutionCtxIdT`. +6. **Slab 5**: Environments — `IEnvironmentT<'s, 'e, 't>` with 9 variants, `TemplatasStoreT<'t>`, builder types, env arena plumbing. +7. **Slab 6**: Expression AST — 3 enums, arena-allocated, `NodeRefT` visitor. +8. **Slab 7**: `CompilerOutputs<'s, 'e, 't>` — all ~25 fields, side tables, deferred-action enum. +9. **Slab 8**: Compiler god struct shell — fields, constructor, top-level driver, `run_typing_pass` entry. +10. **Slab 9**: Function signatures across sub-compilers — file-by-file stub signatures matching Scala, bodies stay `panic!()`. +11. **Slab 10+**: Implementation of individual compilation methods, driven by test pass-rates. + +After Slab 9, the project should build clean with hundreds of `panic!()`s awaiting real implementations. Subsequent slabs implement those. + +--- + +## Part 13: Open Questions / Future Work + +- **Keyword sharing across passes**: if the instantiator can share a `Keywords<'t>` with the typing pass, one arena allocation is avoided. Not critical. +- **Arena-backed HashMap**: at very large program scales, even `CompilerOutputs`'s heap HashMaps could become a bottleneck. `docs/reasoning/arena-deterministic-maps.md` discusses `ArenaIndexMap`. Future optimization if needed. +- **Lifetime bound `'t: 'e`**: may or may not be needed explicitly depending on rustc's inference. Safe to add. Harmless either way. +- **Parallelization**: the design is single-threaded (`!Sync` arenas, stack `CompilerOutputs`). Parallelizing per-function compilation is a future topic, not addressed here. +- **Source 4 (GeneralEnvironmentT id reuse)**: Scala has intentional id collisions at EdgeCompiler.scala:468 and InferCompiler.scala:477, 496. Since we don't require env-id uniqueness, these translate directly.

All ~20 sub-compilers and 15 macros merged onto a single `Compiler<'s, 'ctx, 't>`. Macro dispatch via four Copy unit-variant enums. Vestigial `*Compiler` PhantomData holders deleted. Only `Compiler` remains. `IInfererDelegate` stays vestigial (fn signatures in `compiler_solver.rs` still take `&dyn`; later cleanup). See `FrontendRust/docs/migration/handoff-god-struct-progress.md`. + +**Phase 3 — body migration (Slabs 0–14+)** — data-definition and half of signature-rewrite complete; ~122 method signatures remain before body migration. +- ✅ **Slab 0**: arena substrate scaffolding. +- ✅ **Slab 1** (leaf types): merged as commit `9fd7641c`. +- ✅ **Slab 2** (name hierarchy): tagged `slab-2-complete`. `IdT` is **monomorphic** (not generic `T: Copy` as described in §6.3 below — see `FrontendRust/docs/reasoning/idt-typed-view-alternatives.md`). Sub-enum families (`INameT`, `IFunctionNameT`, etc. — 22 of them) went **inline-owned** (not interned) as part of this slab. +- ✅ **Slab 3** (Kind/Coord/Templata trio): tagged `slab-3-complete`. `KindT` and `ITemplataT` also went **inline-owned** wrappers with `&'t` refs to interned concrete payloads (same philosophy as Slab 2). `PrototypeT` and `SignatureT` are monomorphic. +- ✅ **Slab 4** (environments + real interner bodies): tagged `slab-4-complete`. 9 env structs + 2 wrapper enums + sibling `IInDenizenEnvironmentT` + `GlobalEnvironmentT` + `TemplatasStoreT` + `IEnvEntryT` + variable types; 9 env-specific builders with `build_in(interner) -> &'t`. `TypingInterner<'s, 't>` gained real bodies with 6 family-level HashMaps keyed on tagged-union Val enums (`INameValT` / `InternedKindPayloadValT` / `InternedTemplataPayloadValT`), plus ~84 per-concrete wrappers via macros. Envs override `quest.md` §3.1 to live in `'t`, not `'s` (a `'s`-allocated env can't hold `&'t` refs; see §3.1 below). Five heavy-templata env refs flipped from `&'s` to `&'t`. `NodeEnvironmentBox`, `FunctionEnvironmentBoxT`, and `IDenizenEnvironmentBoxT` deleted — builder-freeze pattern subsumes them. Full spec + retrospective: `FrontendRust/docs/migration/handoff-slab-4.md`; current arena architecture: `FrontendRust/docs/architecture/typing-pass-arenas.md`; long-term storage target: `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md`. +- ✅ **Slab 5** (expression AST): tagged `slab-5-complete`. 3 enums (`ReferenceExpressionTE` 48 variants, `AddressExpressionTE` 5 variants, `ExpressionTE` 2-variant wrapper) + 53 payload structs + `IExpressionResultT` / `ReferenceResultT` / `AddressResultT`. `#[derive(PartialEq, Debug)]` family-wide (because of `f64` in `ConstantFloatTE`). Handoff at `FrontendRust/docs/migration/handoff-slab-5.md`. +- ✅ **Slab 6** (`CompilerOutputs` data shape): tagged `slab-6-complete`. 23-field struct + `::new()` constructor + `PtrKey<'t, T>` newtype in its own module + `DeferredActionT<'s, 't>` 2-variant enum replacing the two `DeferredEvaluatingFunction*` stubs. Method stubs left as free-fn panics (see Slab 8). Handoff at `handoff-slab-6.md`. +- ✅ **Slab 7** (`HinputsT` residual cleanup + Compiler scaffolding + `run_typing_pass` entry point): tagged `slab-7-complete`. Two `()` → `&'t PrototypeT<'s, 't>` flips in `hinputs_t.rs` (`InstantiationBoundArgumentsT.rune_to_bound_prototype` + `InstantiationReachableBoundArgumentsT.citizen_rune_to_reachable_prototype`); `_phantom` field deleted; `Compiler::compile_program` and `Compiler::drain_all_deferred` panic-stub methods added; `run_typing_pass` free fn in `compilation.rs` with the `ScoutArena` / `TypingInterner` / `Keywords` / `TypingPassOptions` / `ProgramA` entry-point signature. Handoff at `handoff-slab-7.md`. +- ✅ **Slab 8** (`CompilerOutputs` method signatures): tagged `slab-8-complete`. All 54 private free-fn stubs in `compiler_outputs.rs` lifted into one-fn `impl<'s, 't> CompilerOutputs<'s, 't> where 's: 't` blocks with correct `&self`/`&mut self` receivers, arena-ref returns (`&'t`), `IdT` by value, `PtrKey` HashMap key wrapping in the `get_instantiation_name_to_function_bound_to_rune` return, and Slab-4 `&'t IInDenizenEnvironmentT<'s, 't>` on all env params. Panic messages bumped to `"Unimplemented: Slab 10 — body migration"` (superseded by subsequent re-scoping; see §12.1). Handoff at `handoff-slab-8.md`. +- ✅ **Slab 9** (`object TemplataCompiler` method signatures): tagged `slab-9-complete`. All 35 private free-fn stubs in `templata_compiler.rs` lifted into one-fn `impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't` blocks with `&self` receiver (god-struct refactor pattern, matching the existing 14 `class TemplataCompiler` impls at the file tail). `interner` and `keywords` parameters dropped across every signature (accessed via `self.typing_interner` / `self.keywords`). `bound_arguments_source: &'t dyn IBoundArgumentsSource<'s, 't>` on substitute_* methods (marker-trait dysfunction acknowledged as Slab 15+ cleanup). `IPlaceholderSubstituter` returns placeholder-`()` with TODO (trait not yet defined). Handoff at `handoff-slab-9.md`. +- ⏳ **Slabs 10–13** (remaining method signatures across sub-compilers): ~122 methods inside existing `impl Compiler` blocks are still bare `(&self)` with Scala `/* def ... */` anchors showing real params, plus ~6 methods in `compiler.rs` with `()`-placeholder param/return types and ~7 orphan free-fn stubs (`local_helper.rs`, `struct_compiler.rs`, `compiler.rs` static utilities). Proposed grouping: **Slab 10** — `compiler.rs` residuals + local_helper/struct_compiler orphans + `templata_compiler.rs` 14 tail methods (~27 sigs); **Slab 11** — expression layer (`expression_compiler.rs` 21 + `pattern_compiler.rs` 12 + `block_compiler.rs` 2 + `call_compiler.rs` 4 = ~39 sigs); **Slab 12** — solver + resolver (`infer_compiler.rs` 14 + `overload_resolver.rs` 11 + `impl_compiler.rs` 9 + `reachability.rs` 1 = ~35 sigs); **Slab 13** — function/citizen/macros (`function_compiler.rs` 8 + `function_body_compiler.rs` 3 + `destructor_compiler.rs` 2 + `struct_compiler_core.rs` 6 + `anonymous_interface_macro.rs` 4 = ~23 sigs). +- ⏳ **Slab 14+** (method body migration): driven by failing tests. Begin with trivial `CompilerOutputs` one-liner bodies (e.g. `lookup_function` = `self.signature_to_function.get(&PtrKey(signature)).copied()`) to establish the pattern, then graduate to TemplataCompiler id-transforms, then substitution engine, then sub-compiler bodies. `ICompileErrorT` variant filling and the `IBoundArgumentsSource` marker-trait → enum conversion land inside this phase as body patterns demand them. + +**Prior overrides, now folded into this doc.** The inline-owned-wrapper refactor (IdT monomorphic; `KindT`/`ITemplataT`/name-sub-enums as inline wrappers over interned concrete payloads) that Slabs 2-3 shipped has been incorporated in §§6.1-6.7. The env `'t`-arena correction and sibling `IInDenizenEnvironmentT` enum decided during Slab-4 planning is reflected in §3. Historical context for both is in `docs/reasoning/idt-typed-view-alternatives.md` and `docs/reasoning/environments-per-denizen-long-term.md` respectively. `TL-HANDOFF.md` at repo root keeps a running list of overrides for anyone auditing the sequence of decisions. + +Build is clean throughout: `cargo check --lib` passes with 0 errors and 0 warnings. + +Known deferred items (separate from the slab plan): +- `HinputsT` now has real fields as of Slab 7 (11 fields, Vec/HashMap-backed per documented AASSNCMCX deviation). Its ~10 `lookup_*` method stubs and the `sub_citizen_to_interface_to_edge` post-hoc-computed field materialization are Slab 14+ body-migration work. +- Sub-compiler free-fn stubs in `env/environment.rs` / `env/function_environment_t.rs` (`entry_matches_filter`, `entry_to_templata`, `lookup_with_name_inner`, etc.) are slice-pipeline artifacts; Slabs 10-13 either wire them into `Compiler` methods or delete them during the per-file signature sweeps. +- Macro dispatcher methods on `Compiler` (`dispatch_function_body_macro` etc.) are not wired yet — Slab 14+, once env-based macro resolution bodies are needed. +- `IInfererDelegate` trait stays vestigial because `compiler_solver.rs` fn sigs still reference `&dyn IInfererDelegate`. Slab 12 signature rewrites remove it. +- `IBoundArgumentsSource` is a marker trait (empty body + two empty unit structs) that the Scala code pattern-matches against. Slab 9 passes it as `&'t dyn` in signatures; Slab 14+ body migration flips it to a pattern-matchable enum when the first body demands it. +- `IPlaceholderSubstituter` trait referenced by `get_placeholder_substituter` / `get_placeholder_substituter_ext` return types doesn't exist yet as a Rust trait. Slab 9 returns `()` with TODO comments; Slab 14+ defines the trait and fills returns. +- `ICompileErrorT<'s, 't>` enum stays `_Phantom`-only with ~80 Scala variants in `/* */` blocks. Variant filling is Slab 14+ as failing tests demand specific errors. +- `LocationInFunctionEnvironmentT.path: Vec` in `ast/ast.rs` violates AASSNCMCX (heap `Vec` inside a conceptually-arena type). Not blocking; a future cleanup flips it to `&'t [i32]`. +- **Typing storage → two-tier per-denizen arenas** is the scheduled post-signature-rewrite redesign. Migration-phase uses one `'t` arena; the deferred design splits storage into a program-wide `'out` outputs arena (resolved definitions + skeleton envs + interned types) and per-top-level-denizen `'scratch` scratchpad arenas (working envs + transient templatas + solver state), with a side-table + `EnvIdx(u32)` for arena-struct → scratchpad-env handoff. Bounds peak memory per-denizen; enables `HashMap`-in-env for O(1) method lookup; avoids `Rc`-in-arena leak hazards. Predicated on an empirical cross-denizen edge audit (full findings in the reasoning doc). Further out, this is also the load-bearing step toward LSP support. See `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md`. + +### The Trade + +- **Cost:** scout arena memory (FunctionA/StructA/etc.) retained through instantiation; typing arena memory (envs, typing-pass output) retained through instantiation. Rough estimate: hundreds of MB to a few GB for large programs. Fine for batch compilation; reconsider for long-running LSP-style use. +- **Benefit:** the port maps to Scala line-for-line in most places. No side-table plumbing. Faster to implement, easier to review for Scala parity. + +--- + +## Part 1: Arena and Lifetime Model + +### 1.1 Three Arenas + +- **`'p` — Parser arena (`ParseArena<'p>`)**: parser AST, `StrI<'p>`, coords. +- **`'s` — Scout arena (`ScoutArena<'s>`)**: postparser + higher-typing output (`FunctionA<'s>`, `StructA<'s>`, etc.), interned postparser names (`INameS<'s>`, `IRuneS<'s>`, `IImpreciseNameS<'s>`). Unchanged for the typing pass. +- **`'t` — Typing arena (`TypingInterner<'t>`)**: interned typing-pass types (names, kinds, coords, templatas), typing-pass output AST (`FunctionDefinitionT`, expressions, `HinputsT`), **and typing-pass environments** (`IEnvironmentT` and its 9 concrete variants). Created before the typing pass; outlives the typing pass. + +All three arenas use `bumpalo`. Arena-allocated structs follow AASSNCMCX: no `Vec`/`HashMap`/`String` inside arena types. + +### 1.2 Lifetime Invariants + +1. **`'s` outlives `'t`**. Expressed as `where 's: 't` on every output type that transitively holds `&'s` data. Rust does **not** enforce outlives via drop order — we must declare the bound. Representative structs that carry this bound include `HinputsT<'s, 't>`, `IEnvironmentT<'s, 't>`, `KindT<'s, 't>`, and every interned typing-pass type. +2. **`'t` outlives the typing pass.** Created by the caller before `run_typing_pass`; dropped by the caller after the instantiator is done. +3. **`'s` outlives the instantiator**, because `HinputsT<'s, 't>` contains `&'s` refs. Scout arena drops after the instantiator completes (or later). +4. **Only two arena lifetimes beyond `'p`:** `'s` and `'t`. Envs live in `'t` (with `&'s`-lifetimed content like `FunctionA` refs and `INameS` references flowing through via field types). +5. **Arena borrow convention.** Arena parameters use a short borrow lifetime (elided or named `'ctx`), never the arena's own lifetime. Write `&ScoutArena<'s>` or `&'ctx ScoutArena<'s>`, never `&'s ScoutArena<'s>`. Same convention for the typing arena: `&TypingInterner<'t>` or `&'ctx TypingInterner<'t>`. This matches `ParseArena` and `ScoutArena` usage in the parser, postparser, and higher-typing passes. The decoupling works because `arena.alloc(&self, val: T) -> &'t mut T` returns arena-lifetimed data from a short `&self` borrow — callers don't need to hold the arena for all of `'t`/`'s` just to allocate into it. + +### 1.3 Arena Construction Order + +```rust +fn top_level_driver() { + let parse_arena = ParseArena::new(); + // ... parser produces parser AST into 'p ... + + let scout_arena = ScoutArena::new(); + // ... postparser/higher-typing produce into 's ... + + let typing_interner = TypingInterner::new(); + let hinputs = run_typing_pass(&scout_arena, &typing_interner, /* program_a */); + + // ... instantiator runs over HinputsT<'s, 't> ... + + // typing_interner drops (after instantiator): 't dies + // scout_arena drops: 's dies + // parse_arena drops: 'p dies +} +``` + +Rust's drop order (reverse of declaration) naturally enforces `'t < 's < 'p` lifetime nesting. + +### 1.4 Where Each Type Lives + +| Type | Lifetimes | Arena | +|---|---|---| +| `HinputsT` | `<'s, 't>` | `'t` for the struct itself, holds `&'s` and `&'t` refs | +| `FunctionDefinitionT`, `StructDefinitionT`, `InterfaceDefinitionT`, `ImplT`, `EdgeT` | `<'s, 't>` | `'t` | +| `KindT`, `IdT`, `INameT`, `ITemplataT` (all variants) | `<'s, 't>` | `'t`, interned | +| `CoordT` | `<'s, 't>` | inline Copy, not interned | +| `ReferenceExpressionTE`, `AddressExpressionTE` | `<'s, 't>` | `'t`, not interned | +| `OverloadSetT` | `<'s, 't>` | `'t`, interned | +| `FunctionTemplataT`, `StructDefinitionTemplataT`, etc. | `<'s, 't>` | `'t`; hold `&'s FunctionA`/`&'s StructA` directly | +| `IEnvironmentT` and sub-types | `<'s, 't>` | `'t` (allocated in typing arena; see §3.1) | +| `GlobalEnvironmentT` | `<'s, 't>` | `'t`; one per typing pass | +| `CompilerOutputs` | `<'s, 't>` | stack-owned; heap-backed HashMaps; dies at pass end | +| `Compiler` (god struct) | `<'s, 'ctx, 't>` | stack; dies at pass end | + +### 1.5 Full Type Inventory — Which Arena Each Type Lives In + +A complete per-type checklist for Slabs 1–6.

Each is a 16-byte inline Copy value (tag + 8-byte concrete ref). +- Kind wrapper enums: `KindT<'s, 't>`, `ICitizenTT<'s, 't>`, `ISubKindTT<'s, 't>`, `ISuperKindTT<'s, 't>` — same pattern. Non-primitive variants hold `&'t StructTT` etc.; primitive variants (`Never`, `Void`, `Int`, `Bool`, `Str`, `Float`) hold tiny Copy payloads inline. +- `ITemplataT<'s, 't>` — also inline wrapper. Variants mix `&'t` refs to interned templata payloads with inline Copy-value variants (`Integer(i64)`, `Boolean(bool)`, `Mutability(MutabilityTemplataT)`, etc.). +- `CoordT<'s, 't>` — passed by value, `kind: KindT<'s, 't>` inline. +- `OwnershipT`, `MutabilityT`, `VariabilityT`, `LocationT`, `RegionT` — pure Copy enums. +- Small templata value variants: `MutabilityTemplataT`, `VariabilityTemplataT`, `OwnershipTemplataT`, `RuntimeSizedArrayTemplateTemplataT`, `StaticSizedArrayTemplateTemplataT`. +- Env wrapper enums (Slab 4): `IEnvironmentT<'s, 't>` (9 variants, each holding `&'t FooEnvironmentT`), `IInDenizenEnvironmentT<'s, 't>` (6-variant subset with the same `&'t` payloads), `IEnvEntryT<'s, 't>` (5-variant: `Function`/`Struct`/`Interface`/`Impl` holding `&'s …A<'s>`, `Templata` holding `ITemplataT<'s, 't>`), `IVariableT<'s, 't>` (4 concrete-by-value variants), `ILocalVariableT<'s, 't>` (2-variant subset). + +**Casting identity rule.** Wrapper enums compare structurally on their 16 bytes (tag + inner ref). Concrete payloads and interned templata payloads compare via `ptr::eq` on the `&'t` ref. Casting up a sub-enum hierarchy (concrete → sub-enum → super-sub-enum → widest) is a stack-only rewrap via `From`/`TryFrom` impls; no interner involvement. + +**Neither arena (stack / heap-Vec / HashMap):** +- `CompilerOutputs<'s, 't>` — stack-owned accumulator, dies at pass end +- `Compiler<'s, 'ctx, 't>` — stack god struct +- Env builders (`NodeEnvironmentBuilder`, `FunctionEnvironmentBuilder`, `TemplatasStoreBuilder`, etc.) — stack-local with heap `Vec`s / `HashMap`s until `build_in(&TypingInterner<'t>)` freezes into `'t`. +- `DeferredActionT` entries in `VecDeque` — owned structs, not `Box` + +### 1.6 Mutual-Recursion Shape + +The interned type graph is mutually recursive but every edge is an `&'s` or `&'t` ref — pointer-sized, finite. No `Box`/`Vec` needed in arena types. + +``` +CoordT → KindT → StructTT → IdT → INameT → ITemplataT → CoordT + ↓ + (also CoordT → KindT directly via CoordT.kind field) +``` + +Same-type self-recursion (e.g. `ForwarderFunctionNameT.inner: &'t IFunctionNameT<'s, 't>`, `ForwarderFunctionTemplateNameT.inner: &'t IFunctionTemplateNameT<'s, 't>`) is resolved by the `&'t` indirection — no `Box`. + +**Ordering implication for Slab filling:** since every edge is a reference, you can declare types in any order within a slab — forward declaration is free. But for human review and staged compilability, order from leaves upward: primitives → `RegionT`/`CoordT` inline → `IdT` generic → `INameT` hierarchy → non-primitive `KindT` variants → `ITemplataT` → prototype/signature → envs → expressions. + +--- + +## Part 2: The God Struct + +### 2.1 Architecture + +All Scala sub-compilers collapse into a single `Compiler` struct: + +```rust +pub struct Compiler<'s, 'ctx, 't> { + pub scout_arena: &'ctx ScoutArena<'s>, + pub typing_interner: &'ctx TypingInterner<'t>, + pub keywords: &'ctx Keywords<'s>, // scout-interned keywords are fine + pub opts: &'ctx TypingPassOptions<'s>, +} +``` + +Immutable configuration only. Mutable state threads through `&mut CompilerOutputs<'s, 't>` on every call. + +**Not on the god struct:** +- `global_env` — Scala builds `globalEnv` as a local inside `compile()`, not as a constructor arg. We do the same: the top-level env is a method parameter on `compile_program` (and anything downstream that needs it), not a field. +- `name_translator` — Scala's `NameTranslator` is a pure helper class with no state; its methods just translate postparser names through the interner. In Rust, every `Compiler` method already has `self.scout_arena` and `self.typing_interner`, so the helper adds nothing. Its ~6 translate methods move directly onto `impl Compiler` and the struct is deleted. + +### 2.2 `&self` + `&mut coutputs` Enables Re-entrancy + +Deep mutual recursion works because `&self` allows shared borrow, and `&mut coutputs` is re-borrowed at each call level. + +### 2.3 Macros + +Macros (`AsSubtypeMacro`, `LockWeakMacro`, `StructDropMacro`, etc.) were stateful classes in Scala (holding `keywords`, `expressionCompiler`, etc.). In the god-struct refactor, all that state is already on `Compiler`. So macro structs disappear entirely and their methods become ordinary methods on `Compiler`. + +Dispatch is via a small Copy unit-variant enum per Scala macro trait — `FunctionBodyMacro`, `OnStructDefinedMacro`, `OnInterfaceDefinedMacro`, `OnImplDefinedMacro`. Each variant tags which `Compiler` method to call. + +```rust +pub enum FunctionBodyMacro { + LockWeak, + AsSubtype, + StructDrop, + StructConstructor, + // ... one variant per Scala class extending IFunctionBodyMacro +} + +impl<'s, 'ctx, 't> Compiler<'s, 'ctx, 't> where 's: 't { + // Individual method per Scala class, name-suffixed to avoid collisions. + pub fn generate_function_body_lock_weak( + &self, + coutputs: &mut CompilerOutputs<'s, 't>, + env: &FunctionEnvironmentT<'s, 't>, + // ... + ) -> (FunctionHeaderT<'s, 't>, ReferenceExpressionTE<'s, 't>) { ... } + + // Central dispatcher for dynamic lookups out of the env. + pub fn dispatch_function_body_macro( + &self, + which: FunctionBodyMacro, + coutputs: &mut CompilerOutputs<'s, 't>, + env: &FunctionEnvironmentT<'s, 't>, + // ... + ) -> (FunctionHeaderT<'s, 't>, ReferenceExpressionTE<'s, 't>) { + match which { + FunctionBodyMacro::LockWeak => self.generate_function_body_lock_weak(coutputs, env, /* ... */), + FunctionBodyMacro::AsSubtype => self.generate_function_body_as_subtype(coutputs, env, /* ... */), + // ... + } + } +} +``` + +A given macro may appear in multiple enums iff Scala had it extending multiple traits (e.g. `StructDropMacro extends IFunctionBodyMacro with IOnStructDefinedMacro` → appears in both `FunctionBodyMacro` and `OnStructDefinedMacro`). Globally the shared implementation is a single `Compiler` method per Scala method, reused across the dispatcher matches. + +### 2.4 Delegate Traits Eliminated + +In Scala, sub-compilers wired via delegate traits. With the god struct, every method calls `self.method(...)` directly. No `IExpressionCompilerDelegate`, `IInfererDelegate`, etc. + +--- + +## Part 3: Environments + +### 3.1 Arena-Allocated In `'t` + +Environments are allocated directly into the typing arena `'t`. They reference scout data (`FunctionA`, `StructA`, `INameS`) freely via `&'s` fields and reference interned typing-pass data (`IdT`, `ITemplataT`, `KindT` payloads) via the inline wrappers + `&'t` refs defined in Slabs 2-3. + +**Why `'t`, not `'s`** (this corrects earlier versions of this doc): envs hold `TemplatasStoreT` which stores `IEnvEntryT::Templata(ITemplataT<'s, 't>)`, which transitively holds `&'t` refs to interned typing-pass payloads. A struct with lifetime `'s` can only hold `&'x` references where `'x: 's`. Since `'s: 't` (scout outlives typing), `'t: 's` is false — so `'s`-allocated envs cannot hold `&'t` refs. Envs must live in `'t`. The lifetime ordering is still fine: `'t` outlives the typing pass; envs die together with all other typing-pass output when the typing arena drops. + +Two parallel wrapper enums. Both hold `&'t` refs to the same concrete payloads, so casting between them is stack-only rewraps (no interner involvement). `IInDenizenEnvironmentT` is a 6-variant subset of `IEnvironmentT`'s 9 — the envs that represent "a denizen currently being compiled." + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub enum IEnvironmentT<'s, 't> { + Package(&'t PackageEnvironmentT<'s, 't>), + Citizen(&'t CitizenEnvironmentT<'s, 't>), + Function(&'t FunctionEnvironmentT<'s, 't>), + Node(&'t NodeEnvironmentT<'s, 't>), + BuildingWithClosureds(&'t BuildingFunctionEnvironmentWithClosuredsT<'s, 't>), + BuildingWithClosuredsAndTemplateArgs(&'t BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT<'s, 't>), + General(&'t GeneralEnvironmentT<'s, 't>), + Export(&'t ExportEnvironmentT<'s, 't>), + Extern(&'t ExternEnvironmentT<'s, 't>), +} + +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub enum IInDenizenEnvironmentT<'s, 't> { + Citizen(&'t CitizenEnvironmentT<'s, 't>), + Function(&'t FunctionEnvironmentT<'s, 't>), + Node(&'t NodeEnvironmentT<'s, 't>), + BuildingWithClosureds(&'t BuildingFunctionEnvironmentWithClosuredsT<'s, 't>), + BuildingWithClosuredsAndTemplateArgs(&'t BuildingFunctionEnvironmentWithClosuredsAndTemplateArgsT<'s, 't>), + General(&'t GeneralEnvironmentT<'s, 't>), + // No Package/Export/Extern — those are not InDenizen in Scala. +} + +pub struct NodeEnvironmentT<'s, 't> { + pub parent_function_env: &'t FunctionEnvironmentT<'s, 't>, + pub parent_node_env: Option<&'t NodeEnvironmentT<'s, 't>>, + pub node: &'s IExpressionSE<'s>, + pub life: LocationInFunctionEnvironmentT<'s>, + pub templatas: TemplatasStoreT<'s, 't>, + pub declared_locals: &'t [IVariableT<'s, 't>], + pub unstackified_locals: &'t [IVarNameT<'s, 't>], + pub restackified_locals: &'t [IVarNameT<'s, 't>], + pub default_region: RegionT, +} +``` + +Every env variant carries `global_env: &'t GlobalEnvironmentT<'s, 't>` (Scala parity; Scala's `IEnvironmentT` has `def globalEnv`). `NodeEnvironmentT` omits it because it delegates via `parent_function_env.global_env` (matching Scala's `override def globalEnv = parentFunctionEnv.globalEnv`). + +`IEnvEntryT<'s, 't>` is a 5-variant inline Copy enum (Slab 4 materializes it out of Scala's `IEnvEntry` sealed trait): + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub enum IEnvEntryT<'s, 't> { + Function(&'s FunctionA<'s>), + Struct(&'s StructA<'s>), + Interface(&'s InterfaceA<'s>), + Impl(&'s ImplA<'s>), + Templata(ITemplataT<'s, 't>), +} +``` + +Not interned. Lives inline in `TemplatasStoreT.name_to_entry`. Five is the full Scala variant count. + +### 3.2 `TemplatasStoreT` Uses Arena-Backed Slice Pairs + +Following AASSNCMCX, we avoid heap HashMap inside arena types. Slices live in `'t`: + +```rust +#[derive(PartialEq, Eq, Hash, Debug)] +pub struct TemplatasStoreT<'s, 't> { + pub templatas_store_name: &'t IdT<'s, 't>, + pub name_to_entry: &'t [(INameT<'s, 't>, IEnvEntryT<'s, 't>)], + pub imprecise_to_entries: &'t [(&'s IImpreciseNameS<'s>, &'t [IEnvEntryT<'s, 't>])], +} +``` + +- **`name_to_entry`** — unsorted arena slice. Linear scan in lookup. +- **`imprecise_to_entries`** — nested-slice layout: outer slice of `(key, inner_slice)` pairs; each inner slice is its own arena allocation containing the (1-3 typical, occasionally more) entries sharing that imprecise name. + +Unsorted slices, linear-scan lookup (`.iter().find(...)` / `.iter().filter(...)`). Common-case scope size is small (~5–10 entries), where linear scan beats binary search on cache behavior and avoids the sort cost at construction. If profiling later identifies a hot slow scope (a package-level env with hundreds of entries, e.g.), switch that specific env kind to sorted-binary or to a different lookup structure — but not as a default. Decision: linear-scan everywhere during migration. + +Lives inline-by-value in env structs (about 48 bytes: 3 slice-pointers + the `&'t IdT` back-ref). + +### 3.3 Mutable Building Phase + +During construction, an env is mutable. Builders live on the stack with heap `Vec`s (and heap `HashMap`s for the imprecise-name index); freeze into the typing arena when done. No `&mut NodeEnvironmentT` over arena-allocated envs — once a `&'t NodeEnvironmentT` is created, it's immutable. Child scopes and mutations produce a fresh builder → fresh arena allocation → fresh `&'t` ref (matches Scala's `NodeEnvironmentBox`, which also allocates a new `NodeEnvironmentT` per mutation): + +```rust +pub struct NodeEnvironmentBuilder<'s, 't> { + pub parent_function_env: &'t FunctionEnvironmentT<'s, 't>, + pub parent_node_env: Option<&'t NodeEnvironmentT<'s, 't>>, + pub node: &'s IExpressionSE<'s>, + pub life: LocationInFunctionEnvironmentT<'s>, + pub templatas_builder: TemplatasStoreBuilder<'s, 't>, + pub declared_locals: Vec>, + pub unstackified_locals: Vec>, + pub restackified_locals: Vec>, + pub default_region: RegionT, +} + +impl<'s, 't> NodeEnvironmentBuilder<'s, 't> { + pub fn build_in(self, interner: &TypingInterner<'t>) -> &'t NodeEnvironmentT<'s, 't> { + // Freeze the templatas builder first — it owns its own heap state. + let templatas = self.templatas_builder.build_in(interner); + // Arena-alloc each slice individually. + let declared_locals = interner.bump().alloc_slice_copy(&self.declared_locals); + let unstackified_locals = interner.bump().alloc_slice_copy(&self.unstackified_locals); + let restackified_locals = interner.bump().alloc_slice_copy(&self.restackified_locals); + interner.bump().alloc(NodeEnvironmentT { + parent_function_env: self.parent_function_env, + parent_node_env: self.parent_node_env, + node: self.node, + life: self.life, + templatas, + declared_locals, + unstackified_locals, + restackified_locals, + default_region: self.default_region, + }) + } +} +``` + +`TemplatasStoreBuilder<'s, 't>` is its own stack builder with `Vec<(INameT, IEnvEntryT)>` for the name-to-entry mapping and `HashMap<&'s IImpreciseNameS<'s>, Vec>>` for the imprecise index (heap HashMap during construction, frozen to nested arena slices on `build_in`). + +Child-scope API: `NodeEnvironmentT::make_child(…)` returns a fresh `NodeEnvironmentBuilder` (not a `&mut NodeEnvironmentT` — infeasible over arena-allocated data). Scala's `makeChild` returns a new case class; Rust returns a builder. `NodeEnvironmentBox` (Scala's mutable wrapper) is deleted in Rust — the builder-freeze pattern subsumes it. + +### 3.4 Transient Reads Use `&IEnvironmentT` + +Scala's `NodeEnvironmentBox.snapshot` is called ~36 times in ExpressionCompiler.scala, mostly for transient reads (passing an `IInDenizenEnvironmentT` to helpers like `isTypeConvertible`). + +In Rust, we distinguish: +- **`&IEnvironmentT<'_, 's, 't>`** (elided lifetime) — read-only borrow of the inline wrapper enum (which holds an `&'t` inside). Zero cost, for helpers that only inspect. +- **`&'t IEnvironmentT<'s, 't>`** or **`IEnvironmentT<'s, 't>` by value** — arena-pinned, needed when storing into a parent pointer, output, or a heavy templata. + +Promotion to `&'t` happens only at explicit "store this env" points (via `build_in(interner)` on a builder). Transient reads just use `&`. Since `IEnvironmentT` is itself a Copy wrapper (16 bytes), callers can also pass it by value cheaply. + +### 3.5 `FunctionTemplata` Is A Plain Computed Value + +Matches Scala directly: + +```rust +impl<'s, 't> FunctionEnvironmentT<'s, 't> { + pub fn templata(&self, interner: &TypingInterner<'t>) -> &'t FunctionTemplataT<'s, 't> { + // FunctionTemplataT is "allocated but NOT interned" — per-call arena alloc, no dedup. + interner.bump().alloc(FunctionTemplataT { + outer_env: self.parent_env, + function: self.function, + }) + } +} +``` + +No caching, no `OnceCell`, no ID minting, no side-table insertion. `FunctionTemplataT` is a small struct holding two pointers — trivially cheap to construct on every call. (Per §1.5 it's arena-allocated into `'t` but not interned; each call allocates a fresh `&'t`.) + +### 3.6 Env-ID Uniqueness Not Required + +Environments don't need unique `id` fields per instance. No HashMap keys on env's own id anywhere in the design: +- `CompilerOutputs.function_name_to_outer_env` etc. are keyed by **function/type template ids** (genuinely unique per Scala's `vassert`). +- OverloadSet holds the env by direct reference, not by id. +- Heavy templatas hold refs, not ids. + +Scala's env-id collisions (NodeEnvironment delegating to parent, GeneralEnvironment reusing caller ids, Box wrappers sharing ids) translate as-is. + +### 3.7 `GlobalEnvironmentT` + +One instance per typing pass, allocated in `'t` early. Every env carries `global_env: &'t GlobalEnvironmentT<'s, 't>` as a back-ref: + +```rust +#[derive(PartialEq, Eq, Hash, Debug)] +pub struct GlobalEnvironmentT<'s, 't> { + pub name_to_top_level_environment: + &'t [(&'t IdT<'s, 't>, TemplatasStoreT<'s, 't>)], + pub builtins: TemplatasStoreT<'s, 't>, +} +``` + +Scala's macro fields (`nameToFunctionBodyMacro: Map[StrI, IFunctionBodyMacro]`, etc.) are **dropped** — macros are methods on `Compiler` now, dispatched via unit-variant enums (see Part 2 and `handoff-god-struct-progress.md`). The struct carries only data. + +### 3.8 Why Not Two-Tier Per-Denizen Arenas (Yet) + +The migration-phase design uses one `'t` typing arena. A post-Slab-8 redesign splits into a program-wide `'out` outputs arena (for resolved definitions, interned types, skeleton envs) and per-top-level-denizen `'scratch` arenas (for working envs, transient templatas, solver state), with a side-table + `EnvIdx(u32)` for arena-struct → scratchpad-env references. That design is driven by `bumpalo`'s no-destructor semantics + an empirical cross-denizen edge audit + wanting per-denizen memory bounds. Full write-up + audit findings: `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md`. Not in scope for this migration. + +--- + +## Part 4: CompilerOutputs + +### 4.1 Structure + +Mutable accumulator threaded through the pass.

Access these with `mem::take` / `drain` + reinsert, not by-reference read. The `Vec` is cheaply movable (pointer-sized entries) so take-and-restore is fine. + +### 4.4 Deferred Actions + +Avoid `Box` via structured enum: + +```rust +pub enum DeferredActionT<'s, 't> { + EvaluateFunctionBody { + prototype: &'t PrototypeT<'s, 't>, + function_env: &'s FunctionEnvironmentT<'s, 't>, + origin: &'s FunctionA<'s>, + }, + EvaluateFunction { + name: &'t IdT<'s, 't>, + calling_env: &'s IEnvironmentT<'s, 't>, + origin: &'s FunctionA<'s>, + template_args: &'t [ITemplataT<'s, 't>], + }, + // Add variants as needed. +} +``` + +Drain loop matches on the variant. No `Box`, no `dyn`, no hidden captures. + +**Invariant:** `DeferredActionT` variants hold only owned or `Copy` context (`&'s` and `&'t` refs, small values). They never reference `CompilerOutputs` itself. This preserves the drain pattern (`pop_front()` → match → call method with `&mut coutputs`) without self-borrow hazards — once the action is popped out, it no longer aliases anything inside `coutputs`, so passing `&mut coutputs` into the handler is safe. + +### 4.5 Speculative Writes Are Idempotent + +During overload resolution, `attempt_candidate_banner` writes to `coutputs` even for candidates that may be rejected.

Matches Scala's `OverloadResolver.scala:210` pattern verbatim. No signature changes to `getCandidateBannersInner` etc. — `&CompilerOutputs` is still threaded through the god-struct methods, but not specifically for env lookup. + +### 5.4 Post-Pass + +`OverloadSetT<'s, 't>` survives in `HinputsT<'s, 't>` inside inert `ReinterpretTE` args. Its `env` and `name` refs remain valid for as long as `'s` lives. The instantiator elides these on sight via `InstantiationBoundArgumentsT.runeToFunctionBoundArg` and never dereferences them — they're type-tag placeholders. + +After the instantiator completes, the caller drops the typing interner (`'t` dies), then the scout arena (`'s` dies), in that order (§1.3). The OverloadSet's refs are never dangling during any live use; after both arenas drop, the entire `HinputsT` is unreachable. + +--- + +## Part 6: Type System Types + +Every lifetime-parameterized struct in this section has an implicit `where 's: 't` bound (§1.2). Representative examples are spelled out on `IdT`, `CoordT`, `KindT`, and `ITemplataT` below; others follow the same convention. + +### 6.1 IDEPFL Dual-Enum Pattern + +All interned typing types use the dual-enum pattern: a **reference enum** (canonical, `&'t` refs) and a **value enum** (transient, HashMap lookup). Scout-lifetimed values (`StrI<'s>`, `IImpreciseNameS<'s>`, `RangeS<'s>`, etc.) are used directly wherever they appear — no re-interning boundary. + +Interned type families (each gets its own HashMap dedup + optional `*ValT` lookup key per IDEPFL): +- Concrete name structs (`FunctionNameT`, `StructNameT`, … ~60). 15 have `&'t [...]` slices and get a transient `*ValT<'s, 't, 'tmp>`; the rest reuse the struct as its own Val (Slab 2 Step 6 convention). +- `IdT<'s, 't>` / `IdValT<'s, 't, 'tmp>` — monomorphic (see §6.3). +- Concrete Kind payloads (`StructTT`, `InterfaceTT`, `StaticSizedArrayTT`, `RuntimeSizedArrayTT`, `KindPlaceholderT`, `OverloadSetT`) — all simple/shallow, reuse struct as Val. +- Interned templata payloads (`CoordTemplataT`, `KindTemplataT`, `PlaceholderTemplataT`, `PrototypeTemplataT`, `IsaTemplataT`) — simple/shallow, reuse struct as Val. `CoordListTemplataT` has an arena slice so it gets `CoordListTemplataValT<'s, 't, 'tmp>`. +- `PrototypeT<'s, 't>` / `PrototypeValT<'s, 't, 'tmp>`, `SignatureT<'s, 't>` / `SignatureValT<'s, 't, 'tmp>` — monomorphic; both contain `IdT` so Val needs `'tmp` for the nested `IdValT`'s slice. + +**Wrapper enums are NOT interned.** `INameT` + 21 name sub-enums, `KindT` + 3 Kind sub-enums (`ICitizenTT`/`ISubKindTT`/`ISuperKindTT`), and `ITemplataT` are all 16-byte inline Copy values. Sub-enum casts between narrow and wide forms are stack-only rewraps via `From`/`TryFrom`. See §6.2 for the names rationale; §6.5 for Kind; `docs/reasoning/idt-typed-view-alternatives.md` for the overarching design. + +**No `'t`-lifetime re-interned versions of `StrI`, `IImpreciseNameS`, `RangeS`, `CodeLocationS`, `PackageCoordinate`, `FileCoordinate`.** Use the scout-arena versions directly. Anywhere you'd be tempted to create a `StrI<'t>` or `RangeT<'t>`, use the existing `StrI<'s>` or `RangeS<'s>` instead. + +### 6.2 INameT Hierarchy + +~60 concrete name types, ~21 sub-trait enums. Every name type carries `<'s, 't>`. + +**DAG rule (critical).** Scala's sealed-trait hierarchy is a DAG — some concrete names extend multiple sub-traits (`ExternFunctionNameT extends IFunctionNameT with IFunctionTemplateNameT`, etc.). In Rust this becomes: **a shared concrete name gets a variant in each sub-enum it belongs to.** Example: + +```rust +pub enum IFunctionNameT<'s, 't> { + Function(&'t FunctionNameT<'s, 't>), + ForwarderFunction(&'t ForwarderFunctionNameT<'s, 't>), + ExternFunction(&'t ExternFunctionNameT<'s, 't>), // also appears below + // ... +} + +pub enum IFunctionTemplateNameT<'s, 't> { + FunctionTemplate(&'t FunctionTemplateNameT<'s, 't>), + ExternFunction(&'t ExternFunctionNameT<'s, 't>), // shared with IFunctionNameT + ForwarderFunctionTemplate(&'t ForwarderFunctionTemplateNameT<'s, 't>), + // ... +} +``` + +**Sub-enums are inline-owned Copy values, NOT arena-interned.** Only the concrete name types (wrapped in the variants above) and `INameT` itself (the widest union of all ~60 concretes) live in the typing arena. The intermediate sub-enums (`IFunctionNameT`, `IFunctionTemplateNameT`, `ICitizenNameT`, etc. — 21 families) are 16-byte `#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)]` values built on the stack when needed. Casting a concrete into a sub-enum, or a narrow sub-enum into a wider one, is a pure stack-only rewrap via `.into()` — no interner round-trip. + +The consequence for identity: two concrete names (e.g. two `&'t FunctionNameT`) are compared via `ptr::eq` since concretes stay interned. Two owned sub-enum values (e.g. two `IFunctionNameT<'s, 't>`, or two `INameT<'s, 't>`) are compared structurally — but since the tag + inner pointer is 16 bytes, this is a 2-word compare and still cheap. + +Bridging via `From for SubEnum` (narrow → wide, infallible — concrete into sub-enum and narrow sub-enum into wider sub-enum) and `TryFrom> for SubEnum` (wide → narrow, fallible, match-and-rewrap on the stack). All of these are real implementations in `names.rs`, no interner involvement. + +**Self-referential variants** (e.g. `ForwarderFunctionNameT.inner: IFunctionNameT<'s, 't>`, `ForwarderFunctionTemplateNameT.inner: IFunctionTemplateNameT<'s, 't>`) are inline-owned; since sub-enums are 16 bytes and Copy they can live directly as struct fields without `Box` or `&'t`. + +No new name variants needed for env handling (env-id uniqueness isn't required). + +### 6.3 `IdT<'s, 't>` — Monomorphic, Interned + +```rust +pub struct IdT<'s, 't> +where 's: 't, +{ + pub package_coord: &'s PackageCoordinate<'s>, // scout-lifetimed + pub init_steps: &'t [INameT<'s, 't>], // inline INameT values + pub local_name: INameT<'s, 't>, // always the widest form +} +``` + +Scala's `IdT[+T <: INameT]` phantom outer parameter is **erased** in Rust — the Rust port is monomorphic. Callers that need a specific leaf-name variant pattern-match on `local_name` at the point of use, like Scala does after `match id.localName`. See `FrontendRust/docs/reasoning/idt-typed-view-alternatives.md` for the full rationale and the alternatives (generic-with-layout-cast, RawIdT+TypedIdT wrapper, etc.) that were considered and deferred for post-migration revisit. + +`IdT` defines custom `PartialEq`/`Eq`/`Hash` (not derive): +- `package_coord`: pointer-eq (scout arena canonicalizes `PackageCoordinate`). +- `init_steps`: slice data pointer + length compare — the typing interner canonicalizes `&'t [INameT]` slices as a whole per IDEPFL, so equal content ⇒ equal slice pointer. +- `local_name`: structural compare on the inline `INameT<'s, 't>` (16 bytes: tag + 8-byte concrete ref). + +Interning uses one HashMap per IDEPFL keyed by `IdValT<'s, 't, 'tmp>` (transient, `'tmp`-borrowed init_steps slice). No widen/try_narrow methods — pattern-match instead. + +### 6.4 `CoordT<'s, 't>` — Inline Copy + +```rust +#[derive(Copy, Clone, PartialEq, Eq, Hash, Debug)] +pub struct CoordT<'s, 't> { + pub ownership: OwnershipT, + pub region: RegionT, + pub kind: KindT<'s, 't>, // KindT is inline (16 bytes), so CoordT is ~24 bytes +} +``` + +Small, Copy, passed by value.

Most links are `&'s` or `&'t` refs — pointer-sized, finite. The name sub-enums (`IFunctionNameT`, `IStructNameT`, etc.) are the exception — they're inline 16-byte tagged pointers, one word larger than a raw ref but still finite and `Copy`.

Every other slot in every other node uses the specific `&'t ReferenceExpressionTE` or `&'t AddressExpressionTE` — no `ExpressionTE` wrapping. When filling expression definitions, default to the narrow type; only reach for `ExpressionTE` when the Scala field was typed as the broader `ExpressionT` AND the node mixes both in a collection. + +### 7.2 Arena-Allocated, Not Interned + +Expression nodes are allocated into `'t` but not deduped.

Rust does not enforce outlives via drop order; the bound must be written. +2. **Arena types never contain `Vec`, `HashMap`, `String`, `Rc`, `Box`.** AASSNCMCX applies. Use arena slices. (One pre-existing exception — `LocationInFunctionEnvironmentT.path: Vec` — is known debt; see `FrontendRust/docs/migration/handoff-slab-4.md` Gotcha 11.) +3. **All HashMap keys on interned refs use `PtrKey<'t, T>`** for pointer-based hash/eq. +4. **Most `CompilerOutputs` HashMap values are pointer-sized `Copy` refs** (`&'s T`, `&'t T`) — enables the copy-out-then-mutate pattern. Exceptions: `sub_citizen_template_to_impls` and `super_interface_template_to_impls` hold `Vec<&'t ImplT>`; access via `mem::take` / `drain` + reinsert. +5. **Speculative writes are idempotent.** No rollback machinery. +6. **Overload resolution always completes during the typing pass.** No unresolved overloads reach the instantiator. +7. **Env equality/hashing never used.** Envs keyed in CompilerOutputs by external (function/type template) ids, not their own id. +8. **Envs live in the typing arena `'t`.** They transitively hold `&'t` refs (via `ITemplataT` in `IEnvEntryT`), so they can't live in `'s`. They drop when `'t` drops (end of typing pass; the instantiator has already consumed what it needs by then — envs don't need to survive past `'t`). +9. **`DeferredActionT` variants never reference `CompilerOutputs`.** All captured context is owned or `Copy` (`&'s`/`&'t` refs, small values). Preserves the `pop_front → match → handler(&mut coutputs)` drain pattern without self-borrow hazards. +10. **Arena parameters use a short borrow lifetime.** `&ScoutArena<'s>` or `&'ctx ScoutArena<'s>`, never `&'s ScoutArena<'s>`.

Single-concern slab focused on expression AST evaluation. +13. ⏳ **Slab 12** (solver + resolver signatures, ~35 sigs): `infer_compiler.rs` 14 + `overload_resolver.rs` 11 + `impl_compiler.rs` 9 + `reachability.rs` 1. `IInfererDelegate` vestigial trait is deleted in this slab as part of the `compiler_solver.rs` signature cleanup. +14. ⏳ **Slab 13** (function/citizen/macros signatures, ~23 sigs): `function_compiler.rs` 8 + `function_body_compiler.rs` 3 + `destructor_compiler.rs` 2 + `struct_compiler_core.rs` 6 + `anonymous_interface_macro.rs` 4. The remaining 17 macro files are already clean per the audit. +15. ⏳ **Slab 14+** (method body migration, driven by failing tests): begin with trivial `CompilerOutputs` one-liners (e.g. `lookup_function` = `self.signature_to_function.get(&PtrKey(signature)).copied()`), then TemplataCompiler id-transforms, then substitution engine, then sub-compiler bodies. `ICompileErrorT` variant filling, the `IBoundArgumentsSource` marker-trait → enum conversion, and the `IPlaceholderSubstituter` trait definition all land inside this phase as body patterns demand them. + +**Per-slab completion criterion:** files in-scope compile in isolation against previously-completed slabs (`panic!` bodies for downstream). The whole crate builds cleanly from Slab 6 onward because every Rust stub now has a valid-if-incomplete signature; adding real param types in Slabs 10-13 doesn't break compilation because no caller currently reaches the panic-stubbed bodies. + +After Slab 13, the build is clean with `panic!()` bodies awaiting implementation. Slab 14+ fills them. + +### 12.2 Immediate Next Action + +Slab 10 (compiler.rs residuals + local_helper/struct_compiler orphans + templata_compiler.rs 14 tail-method sigs, ~27 sigs total). See `TL-HANDOFF.md` at repo root for the transition summary. Handoff doc is **not yet drafted** — incoming TL's first task is to write `FrontendRust/docs/migration/handoff-slab-10.md` in the Slab 8/9 style (translation table, receiver classification, Gotchas). Design spec is Part 2 (god struct) + Slab 9's handoff for the lift-to-Compiler pattern. No design overrides known; the remaining slabs 11-13 follow the same pattern on progressively larger file sets. + +--- + +## Part 13: Open Questions / Future Work + +- **Long-running processes (LSP):** scout arena retention through instantiation is prohibitive for an always-on process. The full trajectory is: first redesign typing storage into two-tier per-denizen arenas (see below), then build LSP on top with DefId-indexed cross-denizen refs + shattered `GlobalEnvironment` + local/global split interner + single-writer cleanup promotion. Sketched in `FrontendRust/docs/reasoning/environments-per-denizen-long-term.md` "Further future direction: LSP support". Concrete design deferred past the per-denizen refactor. +- **Incremental compilation:** serializing `HinputsT` to disk requires a serialization boundary that breaks `'s` refs. Batch compilation only for now. Partially addressed by the LSP trajectory above. +- **Parallelization:** single-threaded design (`!Sync` arenas, stack `CompilerOutputs`). Per-function parallelization is a later topic — the per-denizen design allows it naturally (serialize cleanups, parallelize compiles), but isn't a design constraint today. +- **Arena-backed HashMap (`ArenaIndexMap`):** `CompilerOutputs`'s heap HashMaps could move to arena-backed maps at scale. See `docs/reasoning/arena-deterministic-maps.md`. +- **Typed `IdT` narrowing (post-migration):** the migration-phase `IdT<'s, 't>` is monomorphic — callers pattern-match `local_name` at use sites to narrow. Four post-migration alternatives re-introduce compile-time narrowing (generic-with-layout-cast, unsafe-transmute typed views, `RawIdT` + typed-wrapper pair, status-quo erasure). See `FrontendRust/docs/reasoning/idt-typed-view-alternatives.md`. +- **Reverse-destructor arena.** Candidate crate: `bump-scope` (runs Drop via `BumpBox`). Not required by the current design — it sticks to AASSNCMCX. Revisit if the long-term redesign wants `Rc`-in-arena or heap-collection-in-env. +- **Typing storage → two-tier per-denizen arenas.** Scheduled as a post-signature-rewrite redesign (after Slab 13 lands and the build is clean with panic bodies): program-wide `'out` outputs arena (resolved definitions, interned types, skeleton envs `Package`/`Citizen`/`BuildingWithClosureds`, `HinputsT`) + per-top-level-denizen `'scratch` scratchpad arenas (working envs `Node`/`Function`/`General`/`Export`/`Extern`/`BuildingWithClosuredsAndTemplateArgs`, transient templatas, solver state) dropped at each Phase-3 worklist-item boundary. Side-table + `EnvIdx(u32)` for arena-struct → scratchpad-env references. Bounds peak memory per-denizen, enables `HashMap`-in-env for O(1) method lookup, avoids `Rc`-in-arena leak hazard, forms the natural invalidation unit for eventual LSP. Predicated on an empirical cross-denizen edge audit (findings in the reasoning doc). Three prerequisite refactors identified: `FunctionHeaderT.maybeOriginFunctionTemplata` → `maybeOriginFunctionA`; delete dead `envByFunctionSignature`; keep `BuildingFunctionEnvironmentWithClosuredsT` in `'out`.

Arcana + +**Audience:** Anyone debugging or writing code who encounters a non-obvious cross-cutting effect. + +**Purpose:** Documents a local thing that has surprising, non-obvious effects elsewhere in the codebase. Each arcana has a unique ID (initialism + Z suffix) and `@ID` references at every affected code site. + +The Z suffix is also used for **standalone advisory docs** — reference or pattern docs that describe a concept or procedure but don't have `@ID` backlinks from code sites. The distinction is behavioral: arcana have `@ID` backlinks; advisory docs don't. Advisory docs have no passive discovery mechanism, so they **must** be actively wired: listed via `g_mention_in`, auto-loaded via `g_auto_load_when_editing`, or explicitly linked from another doc's `## See also` section. An unwired advisory doc is invisible. + +**Discovery:** `@ID` comments in code point readers to the arcana doc. The doc lives in the `docs/` directory of the feature that *causes* the cross-cutting effect. + +**Location:** `docs/arcana/-.md` (e.g., `docs/arcana/PostParserSynthesizesParserASTNodes-PPSPASTNZ.md`) + +**Placement:** Arcana and advisory docs that apply across all projects live in `Luz/arcana/`. Only move a doc to `Luz/` if it is genuinely project-agnostic. + +**ID convention:** Uppercase initialism of title words, Z suffix. + +### 4. Shields + +**Audience:** AI agents and reviewers enforcing code quality. + +**Purpose:** Enforceable rules and constraints. Each shield has a unique ID (initialism + X suffix). + +**Discovery:** Guardian discovers shields by scanning for initialisms in parentheses ending in X. Guardian auto-updates the shield list in the containing directory's `CLAUDE.md` as plain markdown links with descriptions from the shield's frontmatter `description:` field. + +**Location:** `docs/shields/-.md` (e.g., `docs/shields/NoExpensiveClones-NECX.md`) + +**ID convention:** Uppercase initialism of title words, X suffix. + +**Placement:** Shields that apply to a specific feature live in that feature's `docs/shields/`.

Not auto-loaded (read on demand). + +**Location:** `docs/migration.md` or `docs/migration/.md` + +### 6. Architecture + +**Audience:** Anyone modifying the feature's own implementation. + +**Purpose:** Internal design, data flow, invariants, and implementation details that a maintainer needs to understand before changing the feature. "Things you have to know to modify this feature's internals." + +**Example:** How the two-phase build-then-freeze lifecycle works inside arena allocation, how the interning dedup HashMap interacts with the bump allocator. + +**Discovery:** Symlinked into `.claude/rules/` for auto-loading when editing the feature's code. + +**Location:** `docs/architecture.md` or `docs/architecture/.md` + +### 7. Reasoning (sub-category of Architecture) + +**Audience:** Anyone wondering "why is it done this way?" or "where is this heading?" + +**Purpose:** Records the alternatives considered and why the current approach was chosen, **and future plans** the code is not yet implementing — target designs, deferred refactors, alternatives held in reserve for post-migration. Software architecture is about evolution, so the place that records *why it looks the way it does today* is also the place that records *where we want it to go*.

Referenced from `.claude/skills//SKILL.md` as a symlink (`SKILL.md → ../../../docs/skills/.md`) so Claude Code's skill loader finds it while the source of truth stays in `docs/`. + +**Location:** `docs/skills/.md` + +### 9. Bugs + +**Audience:** Anyone investigating known issues. + +**Purpose:** Known bugs and limitations are documented as `#[ignore]`'d tests in the nearest `tests` directory, with explanatory comments describing the bug and expected behavior. Tests *are* the bug tracker. + +**Location:** `#[ignore]`'d tests in code, not standalone documents. + +### 10. Requirements + +**Audience:** Anyone wondering what the system should do. + +**Purpose:** Our tests serve as our requirements. They are the source of truth for what the system is expected to do.

The ID is an uppercase initialism of the title words with Z appended. Keep the acronym readable (4-10 letters before the Z). Present to user for approval. + +2. **Draft the arcana text and get a second approval.** Once the user approves the title and ID, write the tentative arcana doc body inline in chat (not to disk yet) and ask the user to approve the text before it's written to a file. The user may want to tweak wording, add nuance, or cut fluff. Only after they approve the drafted text do you move on to step 3. + +3. **Create the arcana doc** at `/docs/arcana/-.md` in the `docs/` directory of the feature that *causes* the cross-cutting effect. HammerCase with the initialism at the end, like `PostParserSynthesizesParserASTNodes-PPSPASTNZ.md`. Include information such as: a brief description of the concept, at least one example concisely illustrating it, why the concept exists, and what its cross-cutting effect is. If there are other arcana that it affects or is affected by it, mention those as part of regular prose (not as an extra section). Notes: + * It should be concise. Don't include fluff. Don't be redundant. Get to the point. + * Instead of long paragraphs, feel free to break things up with newlines. + * It should be one markdown section, it should not have subsections headers. If it must be long enough that subsections are needed, feel free to use bold lines like, `**Interactions with IDKWTHI:**`. + * Instead of having a section starting with `**Cross-cutting effect:**`, start it with something else, like `**How this affects call-sites**:` etc. + * **Focus on *why*, not *what*.** The arcana's job is to explain the strategic reason the code behaves this way — the design invariant, the trade-off, the concern that drives this behavior. It's fine to anchor the reader with a function or type name, but don't narrate tactical implementation: specific call chains, control-flow sequences, "which branch runs when," step-by-step mechanics. Readers come to the arcana for the *why*; they can read the code for the *what*. Tactical narration also dates fast — which is the stronger form of the no-line-numbers rule below. + * Do NOT reference file/line numbers (e.g. `FunctionCompiler.scala:194`). Code moves around constantly and line-anchored references go stale fast. Refer to code by concepts, function names, type names, or module/file names only — readers can find the current location by searching for those.

Use Grep, Glob, and Read. Be thorough — missing a site defeats the purpose. + +5. **Add `@ID` references.** At each relevant site, add a comment referencing the arcana. The reference must always appear in a sentence: + - `// Per @PPSPASTNZ, synthesize a constructor call as parser AST.` + - `// Needed because postparser creates parser nodes (see @PPSPASTNZ)` + + Never write a bare `@ID` without a sentence. The sentence gives local context; the `@ID` tells readers where to find the full explanation. Add references in code as comments, and add references to other documentation and other arcana where relevant. + + **Keep code-comment references concise.** Preferably one sentence. Ideally one line. The arcana doc is the place for the full explanation — the comment just needs to tell the reader "this is an instance of `@ID`, go read it" plus whatever local context is genuinely needed to understand what *this* site is doing. If you find yourself writing a three-line comment explaining the arcana again, cut it — readers can follow the `@ID` to the doc. + +### Shield-specific steps + +If any piece of information is a shield (enforceable rule): + +1. **Generate title and ID.** The ID is an uppercase initialism of the title words with X appended.

You're always writing the skeleton with panics everywhere, not trying to understand all the logic at once. + * **DO** feel free to call unimplemented functions. Feel free to call functions that currently have panics. That is often the correct call.

If the Scala caller checks `results.size > 1`, the Rust caller checks `results.len() > 1` — even if the callee also checks internally. The Scala is the spec; your job is transcription, not reasoning about redundancy. + * **Suspected bugs in Scala:** If you notice something in the Scala code that looks like a bug, still implement the Scala-parity logic exactly as written, but add a `// BUG:` comment explaining your suspicion. Never "fix" the Scala logic during migration. + * If you're unsure about anything, or there's a choice to be made, pause and ask me for help.

Append a new section with a timestamp/heading, then include all the context the TL needs (file paths, line numbers, Scala counterpart, error message, options you considered). The TL reads `for-tl.md` to pick up escalations between turns. You can still mention in chat that you escalated, but `for-tl.md` is the source of truth — chat history is ephemeral, the file is not. **When you escalate, stop — don't keep driving the test in parallel; wait for the TL response in `for-jr.md`. Never defer or skip a test to move on to another one; if you can't solve it, escalate and wait.** + +* **When the architect says just "z," check for `for-jr.md` at the repo root; if it exists, read it (it's the TL's response to your escalation), apply the instructions, and then delete the file.** + +* **temp-disable:** Guardian will be running and watching any commands and edits. Pay attention to what it says, it's trying to keep things going in a good direction. However, if it's objectively wrong about something, or you feel an exception is extremely justified, then feel free to use the `guardian_temp_disable` command to temporarily turn off Guardian for a given definition. + +* **Scaffolding gap escalation:** If you need to call a method that doesn't exist yet on a Rust enum, but the Scala trait *does* have the corresponding `def` (e.g. `parentEnv.globalEnv` where `def globalEnv` exists on the Scala trait but no `fn global_env()` exists on the Rust enum) — this is a scaffolding gap from the slice pipeline. **Do NOT add the method yourself** (Guardian NNDX will rightly block you) and **do NOT temp-disable NNDX**. Instead, STOP and escalate: report what method is missing, which Scala trait defines it, and which Rust enum needs it. The TL will add it. + +* **No inlining:** Guardian will be running and watching any commands and edits, and make sure that your Rust code has 1:1 parity with the old Scala code. When Guardian rejects your code, **DO NOT INLINE** methods as a workaround! Either do what Guardian says, or temp-disable it if it's wrong, or escalate to the TL. + +* **Include enough context in every TL escalation that the TL can find what you're looking at without re-deriving your investigation.** The TL doesn't see your conversation — your escalation message is all they have. At minimum: the Rust file path and line number, the Scala counterpart's file/line, the exact error message if any, and the relevant TFITCX classifications. Quote, don't paraphrase. If you considered multiple options, list them with the trade-offs you saw. + +* **Before escalating "X doesn't exist," grep for it.** Rust names often diverge from Scala (operators like `def +` become `fn add`, `object simpleNameT.unapply` becomes `fn unapply_simple_name`, etc.). Scan the type's `impl` blocks, sibling modules (e.g. `templata_utils.rs` for `TemplataUtils.scala`), and the audit-trail `/* ... */` for a renamed counterpart before declaring something missing. + +* Before escalating an `as_foo_name()` helper, grep for `TryFrom for IFooT` — the documented `+T` erasure pattern uses `.try_into().unwrap()`. + +* **Don't escalate to add a polymorphic method on `INameT`.** When porting `id.localName.fooBar` where Scala's `id` is statically `IdT[ISubTraitNameT]`, the Rust port is `ISubTraitNameT::try_from(id.local_name).unwrap().foo_bar()` — narrow at the use site (§6.0 +T erasure), then call the per-variant method that already exists on the sub-enum. The wide `INameT` doesn't get the method; check the Scala static type of `id` to find the right sub-trait. + +* **When citing a Scala method on a sealed trait, check parent traits too.** `sealed trait ISubKindTT extends KindT` inherits every `def` on `KindT` — the Scala source for an "ISubKindTT method" may actually live on `KindT`. Cite the parent in the escalation so the TL can find it. + +* **Cite Scala paths, not Rust audit-trail lines.** When pointing the TL at a Scala counterpart, cite the actual `Frontend/.../Foo.scala:line`, not the Rust file's quoted comment. Saves the TL a hop. + +* **Missing `import foo.*` in tests: chain the existing resolvers, don't invent helpers.** Three-link chain: `crate::builtins::builtins::get_embedded_modulized_code_map(...)` serves `v.builtins.*` (opt, weak, logic, drop, arith, …); `code_hierarchy::test_from_vec(...)` serves the inline test source; `crate::tests::tests::get_package_to_resource_resolver()` serves on-disk test packages under `FrontendRust/src/tests/` (`printutils`, `panicutils`, `castutils`, `listprintutils`, `genericvirtuals/*`, etc.). `.or(...)` them in that order. If a test errors with `Couldn't find: PackageCoordinate { module: "" }`, the answer is almost always "you didn't include the third resolver" — it is *not* an infrastructure gap, do not escalate to add `` to builtins. Mirror the resolver chain in `tests_destructuring_shared_doesnt_compile_to_destroy` (`compiler_tests.rs:~4152`). + +* **Test patterns: no `if`-guards inside `matches!`. Mirror Scala's two styles directly.** Scala `expr shouldEqual fullyConstructed` ports to `assert_eq!(expr, fully_constructed)` — never `matches!`. Scala `expr match { case Pat(x) => vassert(x.foo) }` ports to a real `match` block with `assert!`s inside the arm — never `matches!(... if x.foo())`. The `if`-guard form has no Scala counterpart and is always a sign the destructuring was shallowed out or that a `shouldEqual` was mis-ported to a `matches!`. If a check needs a method call (like `is_test()`), put it as a bare `assert!` inside the matching arm, exactly like Scala's `vassert` after the `case`. If a literal can be destructured (e.g. `StrI("MyInterface")` matches `pub struct StrI<'s>(pub &'s str)`), inline it in the pattern — don't pull it out into an `if x.field == "..."` guard. Same rule for SPDMX false-positives: don't temp-disable; deepen the destructure or switch to `assert_eq!` with a fully-interned expected value. + +* **Scaffold typo `&'t [TE<'s,'t>]` → `&'t [&'t TE<'s,'t>]` on AST nodes is JR-fixable per SPDMX exception B.** + +* **SPDMX on an in-file precedent pattern: temp-disable yourself.** When SPDMX flags a Rust adaptation pattern that already has a precedent temp-disable in the same file (grep nearby `/*` blocks for `Guardian: temp-disable: SPDMX`), issue the temp-disable via `mcp__guardian__guardian_temp_disable` with a rationale that cites the in-file precedent (e.g. "this `intern_package_coordinate(empty_string, &[])` pattern is the Rust equivalent of `PackageCoordinate.BUILTIN(interner, keywords)`, established in `compile_runtime_sized_array` / `resolve_runtime_sized_array` in this same file"). No escalation needed. + +* **SPDMX vs skeleton-with-panics: escalate, don't temp-disable.** When you're porting a Scala function whose body is a `.map.groupBy.mapValues` / `.foreach` chain and you write a Scala-shaped iteration skeleton with `panic!` in the closure bodies, SPDMX may flag it as "novel scaffolding" or recommend `panic!()` for the whole function. **Both are wrong** — the skeleton IS the Scala parity (per TL.md "Good Partial Implementing"), and whole-function `panic!` breaks the test. The resolution is a TL temp-disable with a standard rationale, but the temp-disable is **TL/architect-level only**. Don't temp-disable SPDMX yourself; STOP and escalate, naming the function you're porting and quoting the Scala body (`.map.groupBy.mapValues` / `.foreach` chain). The TL will issue the temp-disable. + +* **Guardian flags a pre-existing parity issue: fix it if easy, pause if not.** When Guardian rejects an edit because of a parity violation that predates your change (e.g. you're threading a parameter through a function and SPDMX flags a match-arm collapse that was already there), don't reflexively reach for a temp-disable. First ask: "is the underlying parity gap easy to close right here?" If it's a small adjustment (split one match arm into two with a `panic!` in the new arm, restore a `_ => {}` to the Scala-listed variant, add a missing `assert!` line, etc.), just fix it as part of your edit — the temp-disable is a worse outcome than a 5-line parity fix. If closing the gap would need deeper surgery (call-graph changes, new helpers, restructuring beyond the local function, or anything that needs a judgment call about how Scala's logic should land in Rust), **pause and ask the user**. Don't issue a temp-disable as the default escape hatch when the underlying complaint is legitimate. + +* **JR may thread `Result<_, ICompileErrorT>` through any chain of panic-stubbed fns themselves under SPDMX Exception I — no escalation needed.** + +* **When a Scala fn both throws `CompileErrorExceptionT` and returns `Result[_, SomeLocalError]`, mirror it in Rust as nested `Result, ICompileErrorT>` — outer is the always-propagate exception channel, inner is the caller-decides business channel; never merge them.** + +* **Adding an `interner` parameter is always a fine Rust adaptation.** When Scala parity wants something that needs the typing interner (e.g. materializing a `&'t T` snapshot, allocating a slice, re-interning a name) and Scala didn't take an interner because it used GC + mutable references, just thread `interner: &TypingInterner<'s, 't>` through the Rust signature. Don't escalate for this, it won't trip Guardian. + +* **Interner macro wrappers return struct references, not enum variants.** Methods like `intern_typing_pass_block_result_var_name` return `&'t StructType`, not `IVarNameT` — use `.into()` or the From impl to convert to the final enum variant needed. + +* When building values like `ReferenceLocalVariableT` that implement traits in Scala, those will be enums in Rust. Trace the full path to the final enum type (e.g., `ReferenceLocalVariableT` → `ILocalVariableT::Reference` → `IVariableT::ReferenceLocal`) and build from innermost out to avoid multiple rounds of type errors. + +* **The TL only does Guardian-blocked changes.** If Guardian doesn't fire, you don't need to escalate. Threading a new interner/keywords/etc. parameter through call sites, renaming a local to match Scala, fixing an obvious lifetime annotation, adding a `&'t self` receiver where the body needs it — all yours. Escalate only when Guardian prevents you from getting closer to Scala parity. + +* **Check the `///` TFITCX classification before adding `Clone`/`Copy` or other derives to existing types.** When you hit an ownership/borrow error and the obvious fix looks like "add `Clone`" (or `Copy`, or `PartialEq`, or `Hash`), pause and look at the `///` doc comment on the type: + * `/// Arena-allocated (see @TFITCX)` — Clone/Copy explicitly forbidden by the rule ("immutable after construction, no Clone"). The intended access pattern is `&'t T` everywhere; if you need the value in two places, restructure to pass references, not to clone. Common shape: build locally, arena-allocate into the parent struct, return `&parent.field` to get `&'t T`. Adding Clone also breaks @IEOIBZ identity-equality for the type — two arena allocations are supposed to be distinct things. + * `/// Value-type (see @TFITCX)` — Copy/Clone are appropriate and usually already derived. If they're not, check whether the type's fields are all Copy; if yes, fine to add. If no, the type might be misclassified. + * `/// Interned (see @TFITCX)` — Copy is correct (Interned types are tagged-pointer-sized, e.g. `IdT`, name enums); the canonical refs are already Copy. Don't impl Clone manually — derive only. + * `/// Temporary state (see @TFITCX)` — depends. Builders/boxes usually aren't cloned; they're either consumed (`build_in`) or snapshot via `&self`. Ask the TL. + * `/// Miscellaneous` — case by case, ask. + + Same rule applies to `PartialEq`/`Hash` derives: check the classification + the Scala counterpart. If Scala has `vcurious()` equals overrides on the type, mirror with no impl in Rust (compile error > runtime panic). If Scala has structural-by-default and Rust is Value-type, derive. If Rust is Arena-allocated with identity, manual `std::ptr::eq` per @IEOIBZ. **The classification is the spec — don't paper over compile errors by adding derives that contradict it.** When in doubt, escalate. + +* When you need to implement a function, but it will depend on multiple other panicking functions, that's fine. Implement the function. Then run the test, and implement whatever panic you hit next. + +* When replacing a panic, just write the code with your best guess of what the Scala-parity Rust code should be, inspired by the corresponding Scala.

That's your **next gap**. + +3. **Confirm the probe is the right one and the source is Scala-clean.** Before assuming the panic represents a real Rust-side migration gap, verify it isn't a roguelike-source issue: run the Scala-side counterpart at `Frontend/IntegrationTests/test/dev/vale/IntegrationTestsA.scala::"Roguelike typing pass"`: + + ``` + cd /Volumes/V/Sylvan/Frontend && sbt 'testOnly dev.vale.IntegrationTestsA -- -t "Roguelike typing pass"' > ./tmp/scala-probe.txt 2>&1 + ``` + + The Scala test **must pass**. If it doesn't, the roguelike source is itself broken — fix `Frontend/Tests/test/main/resources/programs/roguelike.vale`, sync to `FrontendRust/src/tests/programs/roguelike.vale`, and only then resume the Rust loop. Common roguelike-source issues (already fixed at time of writing, recurrences are still possible): stale stdlib imports, missing `import string.*` for `==(str, str)`, missing `extern func getch() int`, owned-RSA passed to a borrow-taking `each`/`len` (use `drop_into` and `.method()`-on-local-binding-not-on-chained-call). + +4. **Write a minimal Vale-fragment reproducer test** that triggers **only** the gap from step 2. Add it to `FrontendRust/src/typing/test/compiler_project_tests.rs`. The body shape must mirror the existing precedents (`typing_pass_uses_same_instance`, `typing_pass_array_type_convertible`, `typing_pass_tuple_literal`, etc.): direct `TypingPassCompilation::new(..., vec![&BUILTIN, &test_tld], get_code_map(...), ...)` — **not** `compiler_test_compilation`, which only loads TEST_TLD and can't load stdlib-using programs. + + Pick the **smallest** Vale fragment that triggers the panic. Examples from prior loops: + - `set x = 1` inside a lambda → closure-var mutate. + - `x = (3, 4);` → tuple literal eval chain. + - `[a, b] = arr;` where arr is `#[#](3, 4)` → SSA destructure. + - `m = MyStruct(...); destruct m;` → destruct expression eval. + + Each reproducer is **novel code** with no Scala counterpart, so it WILL trip NNDX/NCWSRX/SPDMX. That's a TL/architect-level escalation per `TL.md`'s NNDX rules — **stop and escalate** (paste the test body into `for-tl.md`); don't try to temp-disable yourself.

Go back to step 6 for that new panic. **Don't write a new reproducer test** — the same reproducer is exercising the chain. One reproducer covers the whole chain it triggers. + - **Test fails on the SAME panic at the same file:line:** your port didn't reach the panic site or something went wrong. Inspect. + - **Test fails on a real compile error (no `Unimplemented`/`implement:` in message):** that's a logic bug, NOT a migration gap. Stop and escalate to TL per `migration-drive.md`'s rule. + - **Build error (lifetime, type, signature mismatch):** if it's a small adaptation (param ownership, scoped lifetime), fix it.

If anything that was previously green is now red, you broke something while porting — go figure out what. + +9. **Re-run the probe (step 2) for the next gap.** Loop. + +10. **When the probe passes end-to-end:** un-ignore `typing_pass_on_roguelike` if it's still ignored, run full suite once more, and stop. + +## Discipline rules + +* **One reproducer per probe iteration, not per layer.** The probe surfaces a panic. You write ONE reproducer. As you port layer-by-layer, the reproducer stays the same — you're peeling onion layers, not exploring a new tree. Only when the reproducer goes green and the probe surfaces a DIFFERENT panic do you write a new reproducer. + +* **One Scala body per port.** The temptation is "I see the whole chain, let me port resolve_tuple + make_tuple_coord + make_tuple_kind in one shot." Don't. Port resolve_tuple body only. Run. If next panic is make_tuple_coord, port that body only. Run. If next panic is make_tuple_kind, port that body only. Run. The reason is that each layer might have its own surprises (missing types, signature shape mismatches, untyped helper calls) that don't surface until you're actually building against the layer above. Pre-porting compounds error chains that are hard to unwind. + +* **No speculative body fills.** If a Scala body calls a function whose Rust counterpart is a panic stub, leave it as a panic call — your next reproducer iteration (or the chain's continuation) will hit it and prompt the next port. + +* **Reproducer source must be minimal.** "Minimal" means the smallest Vale fragment that triggers the exact panic. Don't include unrelated constructs that might add OTHER blockers and confuse "did I make progress?" + +* **Reproducer must mirror Benchmark-style setup.** Stdlib resolution requires `vec![&BUILTIN, &test_tld]` AND `get_code_map(...)` (full dual-namespace builtin map), NOT `compiler_test_compilation` (which only loads TEST_TLD with the modulized variant). If your reproducer uses stdlib types (`Opt`, `List`, `HashMap`, `===`, arrays, etc.), `compiler_test_compilation` won't even resolve them. + +* **The Scala probe must be Scala-clean before any Rust ports.** If `IntegrationTestsA::"Roguelike typing pass"` fails in Scala, the Vale source is broken. Don't bury Rust-side workarounds for a broken-in-both-languages source — fix the source first, sync the file to both copies, then resume. + +## Notes + +* **Use the Scala counterpart as the source of truth for each body.** The Rust port translates 1:1 from the `/* ... */` block below the stub. No novel logic, no Rust-idiomatic "improvements" beyond what Rust strictly requires to compile (per `migration-drive.md`). + +* **Adjacent helper calls.** Many Scala bodies call helpers like `localHelper.makeTemporaryLocal(...)`, `destructorCompiler.drop(...)`, `templataCompiler.getPlaceholderSubstituter(...)`. In Rust, these flatten onto `Compiler` (per design v3 §2.1 god struct). Call them as `self.make_temporary_local(...)`, `self.drop(...)`, `self.get_placeholder_substituter(...)`. If the helper is itself a stub, that's fine — the next iteration of step 6 (or 7's continuation) will hit it. + +* **Adding `interner` / `scout_arena` / `keywords` parameters is fine.** Scala uses GC; Rust often needs an arena handle to allocate. SPDMX Exception B covers it. Document with a one-line `// Rust adaptation (SPDMX-B): ` comment above any new arena-taking function. + +* **Stop when you escalate, don't keep driving in parallel.** When you escalate (lifetime puzzle, NNDX-blocked test add, structural change, ambiguous Scala source, anything in `migration-drive.md`'s "stop and escalate" bullets), stop and wait for the TL response in `for-jr.md`. Never defer or skip the current probe iteration to move on. + +* **`for-jr.md` / `for-tl.md` escalation files.** Same as `migration-drive.md`: escalations to TL go in `for-tl.md`; TL responses to JR go in `for-jr.md`. Check `for-jr.md` when the architect says just "z". + +* **Update the probe over time.** As the typing pass approaches end-to-end compilation of roguelike, this skill's probe will graduate to the next real-world program (e.g. one of the stdlib's own tests, or an integration-test sample). When that happens, update step 2's test name and step 3's Scala counterpart. The pattern stays; only the probe target changes. diff --git a/docs/skills/slice-pipeline.md b/docs/skills/slice-pipeline.md new file mode 100644 index 000000000..a93175458 --- /dev/null +++ b/docs/skills/slice-pipeline.md @@ -0,0 +1,107 @@ +--- +name: slice-pipeline +description: Run the full slice migration pipeline on a Rust file in order +--- + +You were pointed at a Rust file that contains commented-out Scala code.

Everything that is inside the Scala `{ }` case body must be inside the Rust `=> { }` arm. + +- **Rust slice patterns are the exact equivalent of Scala `Vector(...)` in pattern position.** `Vector()` → `&[]`, `Vector(x)` → `&[x]`, `Vector(x, y)` → `&[x, y]`. Using these inline avoids the need for post-`assert_eq!(len, N)` + index checks. + +- **Match ergonomics handle `&'t T` field references automatically.** When destructuring a struct whose field is `&'t FooT`, writing `field: FooT { ... }` in the pattern works — no need for `field: &FooT { ... }`.
