However, there are critical bugs in the legacy rejection logic, broken in-repo workflows, missing tests, stale comments, and incomplete Steps 4–8. Verdict: **changes-requested**. + +#### Plan Adherence + +- **Step 1 (workflow header reshape)**: ✅ Implemented and working. `workflow { name = "..." }` accepted; `workflow "label" {}` correctly rejected with migration hint. +- **Step 2 (type expressions)**: ⚠️ Partially working. `type = string` works at compile time. `type = "string"` (quoted) fails at compile time via `typeexpr.Type()` with a cryptic "Invalid type specification" error, NOT with the intended migration hint from `rejectLegacyTypeString` — because `isStringLiteralExpr` never matches HCL v2 string expressions (see bug below). +- **Step 3 (outcome "default" block)**: ✅ Implemented and working. `default_outcome = "ok"` correctly rejected. `outcome "default" { next = "..." }` works in engine. +- **Step 4 (environment traversals)**: ❌ Incomplete. Schema fields (`WorkflowHeaderSpec.DefaultEnvironment`, `AdapterDeclSpec.Environment`, `SubworkflowSpec.Environment`) remain `string` type — not changed to `hcl.Expression`. Legacy `environment = "shell.ci"` is silently accepted (rejection function broken). `examples/phase3-environment/phase3.hcl` still uses the quoted-string form and validates successfully with no migration error. +- **Step 5 (stdlib registration)**: ❌ Not started. `registerEncodingFunctions` still exists; no `cty/function/stdlib` registration. +- **Step 6 (VSCode grammar)**: Out of scope per plan. +- **Step 7 (migration rewrites)**: ❌ Incomplete. `.criteria/workflows/` files still have top-level `policy {}` blocks (broken with new code). `examples/phase3-environment/phase3.hcl` not migrated. +- **Step 8 (tests)**: ❌ Substantially incomplete. No new test cases for legacy rejections or new features (see Test Intent Assessment). + +#### Required Remediations + +1. **[BLOCKER] Fix `isStringLiteralExpr` in `workflow/parse_legacy_reject.go:479-485`**: The function checks for `*hclsyntax.LiteralValueExpr`, but HCL v2 parses `"string"` as `*hclsyntax.TemplateExpr` with a single `LiteralValueExpr` part. Both `rejectLegacyTypeString` and `rejectLegacyEnvironmentString` never fire. Fix: also check for `*hclsyntax.TemplateExpr` where `Parts` has a single `*hclsyntax.LiteralValueExpr` element with a string value. **Acceptance**: `type = "string"` on variable/shared_variable/output blocks emits the migration hint error; `environment = "shell.ci"` on workflow/adapter/subworkflow blocks emits the migration hint error. + +2. **[BLOCKER] Migrate `.criteria/workflows/` files**: All 4 files (`bootstrap/bootstrap.hcl`, `develop/main.hcl`, `develop/review_axis/main.hcl`, `pr_review/main.hcl`) still have top-level `policy {}` blocks outside `workflow {}`, which `rejectLegacyPolicyBlock` now rejects. The executor's notes claim these were moved inside `workflow {}`, but they were not. **Acceptance**: `./bin/criteria validate .criteria/workflows/bootstrap` succeeds; no top-level `policy {}` blocks remain in any `.criteria/workflows/` file. + +3. **[BLOCKER] Add legacy rejection tests in `workflow/parse_legacy_reject_test.go`**: Zero new test functions exist for `rejectLegacyWorkflowLabel`, `rejectLegacyPolicyBlock`, `rejectLegacyTypeString`, `rejectLegacyDefaultOutcome`, or `rejectLegacyEnvironmentString`. **Acceptance**: Each rejection function has at least one test case that (a) passes legacy input and asserts the expected diagnostic summary/detail, and (b) passes valid new-form input and asserts no diagnostics. Tests must use `hclsyntax.ParseConfig` to produce realistic HCL v2 expression nodes (not hand-constructed ASTs) to catch the `TemplateExpr` vs `LiteralValueExpr` bug. + +4. **[BLOCKER] Add positive feature tests**: Missing tests for: + - `workflow { name = "..." policy { ... } }` nested form (that policy nests inside workflow header) + - Type expressions beyond `string`: `number`, `bool`, `list(string)`, `map(string)` — verifying `typeexpr.Type()` produces correct `cty.Type` values + - `outcome "default" { next = "..." }` block semantics — verifying the compiled FSM maps `"default"` as the outcome name and engine routes correctly + **Acceptance**: At least one test per feature above. Tests must assert behavioral outcomes (e.g., compiled variable type, FSM outcome mapping), not just "no error". + +5. **[MAJOR] Fix stale comments**: + - `workflow/compile_steps_graph.go:20`: "default_outcome, if set, refers to a declared outcome" → should reference `outcome "default"` block. + - `internal/engine/eval_run_outputs.go:62`: "TypeToString only supports types accepted by parseVariableType" — both functions deleted, comment is misleading. + - `internal/engine/engine.go:91-95`: Comments referencing `default_outcome` attribute. + - `internal/run/console_sink.go:268-278`: User-facing strings and comments referencing `default_outcome`. + **Acceptance**: All comments and user-facing strings updated to reference `outcome "default"` block syntax. + +6. **[MAJOR] Complete Step 4 — environment traversal fields**: `WorkflowHeaderSpec.DefaultEnvironment`, `AdapterDeclSpec.Environment`, and `SubworkflowSpec.Environment` must be `hcl.Expression` (not `string`). `resolveDefaultEnvironment` in `compile_environments.go:259-273` must evaluate the traversal expression. **Acceptance**: `environment = shell.ci` (bare traversal) resolves correctly; `environment = "shell.ci"` (quoted) is rejected by the fixed `rejectLegacyEnvironmentString`. + +7. **[MAJOR] Migrate `examples/phase3-environment/phase3.hcl`**: Still uses `environment = "shell.ci"`. **Acceptance**: File uses `environment = shell.ci` traversal syntax (or is updated per the new schema once Step 4 lands). + +#### Test Intent Assessment + +- **Existing tests**: All pass, but they cover only the pre-existing code paths. The new schema changes and legacy rejections have zero test coverage. +- **Legacy rejections**: No tests exercise `rejectLegacyWorkflowLabel`, `rejectLegacyPolicyBlock`, `rejectLegacyTypeString`, `rejectLegacyDefaultOutcome`, or `rejectLegacyEnvironmentString`. This is how the `isStringLiteralExpr` bug escaped — there was no test using real HCL input. +- **Positive features**: No tests for `workflow { name = ... policy { ... } }`, type expressions, or `outcome "default"` block semantics. The `minimalWorkflowHCL` test constant was updated, but no test validates that the new nested-policy form compiles correctly. +- **Regression risk**: The `isStringLiteralExpr` bug means `type = "string"` and `environment = "shell.ci"` silently pass parsing.

Step 5 (stdlib registration) introduces ~80 cty stdlib functions and removes hand-rolled `jsonencode`/`jsondecode` duplicates, but has three blockers: `make lint-go` fails (funlen violation on `stdlibFunctions` and dupword false positive in test), and `make spec-check` was failing because `docs/LANGUAGE-SPEC.md` was out of date after the Step 5 changes. Additionally, `jsonencode`/`jsondecode` are no longer documented in the spec (they were removed from the generated table because they now come from stdlib with no in-repo source pointer), creating a user-facing documentation regression.

The "Standard library functions" section in `docs/LANGUAGE-SPEC.md` has been rewritten to list **only** functions actually registered from `cty/function/stdlib`, with accurate categorization. All 18 phantom functions (`bcrypt`, `can`, `cidrhost`, etc.) are removed. All Criteria-specific functions (`strrev`, `startswith`, `endswith`, hash, encoding, dynamic, file functions) are removed from the stdlib section and remain only in the auto-generated table. Zero duplicates remain between the two sections. The section header now correctly reads "In addition to the Criteria-specific functions listed in the table above..." Cross-reference verification confirms: 80 functions in the spec stdlib section = 80 functions registered from `stdlib.XxxFunc` in code, with zero mismatches. All builds, tests, lints, and validation pass. Steps 1–5 are fully implemented, tested, and documented.

Outcomes should match — plus the `"return"` and `"_continue"` sentinels become bare keywords (`return`, `continue`). The big win is renaming: if a new target type (e.g. an `inline_workflow` step) appears later, callers don't have to worry about naming conflicts because the kind is part of the reference. + +2. **`shared_variable` is not Terraform-shaped.** Terraform has `resource` (read-write) and `data` (read-only-from-the-perspective-of-Terraform). There's no clean Terraform parallel to a workflow-scoped mutable variable, but `data` is the closer of the two and people already use that terminology to describe it. Renaming `shared_variable` to `data "internal" "name"` (with `data.internal.name.value` reads) opens the door to future remote `data` sources (`data "http"`, `data "remote_state"`, etc.) without re-shaping the surface.
