Gergő Magyar	ab077b4c29	feat(ingestion): TypeScript registry-primary scope resolution (Ring 3) (#1050) ... * feat(ingestion): TypeScript registry-primary scope resolution (Ring 3) - Add TypeScript ScopeResolver stack (query/captures/interpret, import decomposition, hooks, arity, merge, receiver binding) and register in SCOPE_RESOLVERS. - Harden shared compound receiver and receiver-bound CALLS pass for map for-of tuple bindings, dotted typeRef shapes, and callable-alias fallbacks. - Flip TypeScript into MIGRATED_LANGUAGES; refresh AGENTS.md and type-resolution-system.md. - Shared finalize-algorithm updates for cross-file scope parity. - Tests: TS scope-resolution unit suite; legacy call-processor suite forces REGISTRY_PRIMARY_TYPESCRIPT=0; registry-primary flag test opts out TS in override scenario. Made-with: Cursor * fix(ingestion): SCC-ordered cross-file return-type propagation + multi-hop re-export resolution Fix CI failures on PR #1050 (TypeScript registry-primary migration) by making `propagateImportedReturnTypes` deterministic via reverse- topological SCC ordering and updating the multi-hop re-export contract to match `followReexportChain` behavior. Why: the legacy pass mirrored an intermediate ref instead of the terminal type when an importer was processed before its source module had its own typeBindings chain-followed (4-file alias chain regression in `ts-simple` fixture: `models.User -> service.user -> app.user` collapsed to `getUser` instead of `User`). Reverse-topological walk of `indexes.sccs` (leaves first) lets every importer see the source's already-followed terminal type in a single pass. Changes: - `imported-return-types.ts`: rewrite to walk SCCs leaves-first, chain- follow the source module's typeBindings BEFORE mirroring, and chain- follow the importer's typeBindings AFTER mirroring. Cyclic SCCs reach a partial fixpoint (no convergence guarantee, ts-circular only asserts no-throw). - `finalize-algorithm.ts`: docstring update on `FinalizeFile.localDefs` to reflect that `followReexportChain` resolves multi-hop re-exports through barrels even when intermediates do not surface the name - surfacing is now a static optimization, not a correctness requirement. - `contract/scope-resolver.ts` Invariant I3: explicitly document the SCC ordering requirement. - `pipeline/run.ts`: split PROF timer into `finalize` and `propagate` so the pass's cost is observable independently. - `ARCHITECTURE.md` Performance notes: describe SCC-ordered propagation. - `imported-return-types.ts`: expand chain-depth comment (2x effective depth from pre/post follow), add multi-ref break rationale, add `ts-simple` motivating-fixture pointer. Tests: - `finalize-algorithm.test.ts`: add 4 cases (3-hop chain, cyclic re-export visited-set guard, wildcard re-export fall-through, multi-source first-match-wins); fix misleading shared nodeId in the thick variant; rename and update the multi-hop test for the new contract (transitiveVia assertion on the thin variant). - `imported-return-types.test.ts` (NEW): unit tests for the SCC pass pinning topological collapse, local-annotation guard, missing-source skip, and cyclic-SCC no-throw. - `cross-file-binding.test.ts` + `ts-deep-alias-chain` fixture (NEW): 5-file integration regression guard for SCC-ordered propagation through 4 module boundaries. Validation: 865 scope-resolution + cross-file tests pass on Windows; typecheck clean across both packages; only pre-existing Swift overload failures remain (verified on PR base commit, environmental). Made-with: Cursor * fix(ingestion): address PR #1050 review findings — side-effect imports, resolve-cache perf, adapter signature Three independent fixes surfaced by the production-readiness review of the TypeScript registry-primary scope-resolution migration (RFC #909 Ring 3). All three pass under both REGISTRY_PRIMARY_TYPESCRIPT=0 and =1. 1. Side-effect imports were silently dropped (correctness regression). The legacy DAG emitted IMPORTS edges for `import './polyfill'` because its tree-sitter query matches `(import_statement source: (string))` regardless of clause. The new registry-primary path returned `[]` from `splitImportStatement()` for clause-less imports, so no ParsedImport / ImportEdge was ever produced — silent file-level edge loss. Add a generic 'side-effect' variant to `ParsedImport` and `ImportEdge['kind']` in `gitnexus-shared`; finalize resolves the target file and pre-finalizes the edge (no `targetDefId`, no `BindingRef`) so the SCC fixpoint loop skips it. The TypeScript provider now emits + interprets the new kind end-to-end. The variant is intentionally generic so other languages (Rust `use foo as _`, Python module-init) can adopt it. 2. Per-import re-derivation in `resolveImportTarget` (perf regression). The TS adapter built `new Set(allFilePaths)` on every call and let `resolveTsImportTarget` re-derive `allFileList` / `normalizedFileList` and discard the `resolveCache`. For a workspace with N files and M imports that's O(N × M) work per pass. Wrap the adapter in a closure that memoizes all five derived values keyed on the orchestrator's `ReadonlySet` identity; reset only when the set reference changes (start of new pass). New cost: O(N + M). 3. Misleading fake `ParsedImport` in the adapter (architecture). The adapter constructed `{ kind: 'named', localName: '_', importedName: '_', targetRaw }` to call `resolveTsImportTarget`, even though only `targetRaw` and the structural-typed context are read. Extract `resolveTsTarget(targetRaw, ctx)` so the adapter has an honest signature; `resolveTsImportTarget` still works for other callers. Also extract `narrowTsContext` for the type narrowing. Tests: - New 4-file fixture `typescript-side-effect-imports` with two side-effect imports + one named import. - New "TypeScript side-effect imports" describe in `test/integration/resolvers/typescript.test.ts` (parity-gated by `ci-scope-parity.yml` — runs under both flag states). - Updated 2 unit tests to expect 1 side-effect ParsedImport and 4 `@import.statement` matches (was 0 / 3). - 785 / 785 TS scope-resolution tests pass under both REGISTRY_PRIMARY_TYPESCRIPT=0 and =1. Made-with: Cursor * fix(scope): address Codex adversarial review findings on PR #1050 Four findings from the Codex adversarial review broke registry-primary TypeScript resolution for common patterns. All four now have unit and integration regression coverage that pass under both `REGISTRY_PRIMARY_TYPESCRIPT=0` (legacy DAG) and the default registry-primary path. [high] tsconfig path aliases dropped: Threaded `tsconfigPaths` through ScopeResolver via a new opaque `resolutionConfig` parameter and a `loadResolutionConfig(repoPath)` hook. The orchestrator (`scopeResolutionPhase` + `runScopeResolution`) loads it once per workspace pass and forwards into every `resolveImportTarget` call. TypeScript resolver now resolves `@/services/user` style imports through the standard resolver's alias branch. [high] TSX parsed with the wrong grammar: `emitTsScopeCaptures` now picks the parser/query by `filePath` (`.tsx` -> TSX grammar) and validates cached trees against the expected grammar via the new exported `tsCachedTreeMatchesGrammar` helper. Stale TS-grammar trees for `.tsx` files no longer leak through the scope query. [medium] Literal dynamic imports never linked: Added `kind: 'dynamic-resolved'` to `ParsedImport` and `ImportEdge`. The decomposer emits a synthetic `@import.literal` capture for string-literal dynamic imports; the interpreter maps that to `dynamic-resolved`; finalize pre-finalizes it as a file-level terminal (same shape as `side-effect`). `import('./feature')` now produces a real IMPORTS edge under the registry-primary path. Legacy DAG keeps its existing behavior — the new integration assertion is gated behind the flag. [medium] Namespace re-exports invisible from barrels: The decomposer now emits TWO captures for `export * as ns from './m'` — the existing `reexport-namespace` import draft AND a synthetic `@declaration.namespace` capture (via `buildNamespaceDeclarationMatch`). The latter creates a Namespace `SymbolDefinition` in the barrel's `localDefs`, so downstream `import { ns } from './barrel'` resolves through `findExportByName`. Regression fixtures under `gitnexus/test/fixtures/lang-resolution/`: - typescript-tsconfig-aliases (`@/` alias) - typescript-tsx-jsx (Button.tsx + App.tsx with JSX) - typescript-dynamic-import (`await import('./feature')`) - typescript-reexport-namespace (`export * as Models from './base'`) Validation: - gitnexus-shared builds clean - gitnexus typecheck clean - 385/385 TS scope-resolution tests pass under both `REGISTRY_PRIMARY_TYPESCRIPT=0` and default Made-with: Cursor * perf(scope): O(1) defById lookup + bounded re-export depth (PR #1050 round 3) Addresses the round-3 PR #1050 reviews (Claude adversarial + xkonjin): both flagged the existing O(N²) `findDefById` linear scan in `materializeBindings` and the unbounded recursion in `followReexportChain` as production-readiness blockers for TypeScript monorepos. Both fixes land alongside their regression tests under both `REGISTRY_PRIMARY_TYPESCRIPT=0` and the default registry-primary path. [high] materializeBindings O(N_files × N_defs × N_edges) → O(N_defs + N_edges): Build a `nodeId → SymbolDefinition` index map once at the top of `materializeBindings` (one O(N_defs) pass), then replace the per-edge `findDefById(files, edge.targetDefId)` linear scan with an O(1) `defById.get(edge.targetDefId)` lookup. Also drop the now-unused `findDefById` helper. At realistic TypeScript monorepo scale (~5k files × ~50 defs/file × ~100k linked import edges) this is the difference between ~25 s and a few ms inside finalize. Regression test in `finalize-algorithm.test.ts` builds 200 leaf files + 1 consumer importing one symbol from each, asserts every binding materializes correctly. [medium] followReexportChain unbounded recursion: The existing `visited` set caps depth at `O(N_files)` but allows recursion proportional to barrel-chain depth, mismatching the explicit "Iterative DFS to avoid stack overflow" policy in `tarjanSccs`. Added a `MAX_REEXPORT_DEPTH = 100` constant and a `depth` parameter to `followReexportChain` (defaults to 0); each recursive call passes `depth + 1` and the function returns `null` when the cap is exceeded. 100 is comfortably above any realistic hand-authored barrel chain (typical depth 1-5; auto-generated barrels rarely exceed 20) while staying well below JS engine call stack limits. Regression test wires a 200-link reexport chain and verifies the crawl terminates cleanly with `linkStatus: 'unresolved'` (no terminal def reachable within the budget). [low] synthesizeInstanceofNarrowings bare-identifier-only limitation: xkonjin's review #4 noted that the LHS narrowing only handles bare identifiers (`if (x instanceof Foo)`), not member expressions (`if (user.address instanceof Address)`). Added a JSDoc note explaining the constraint and pointing readers at field-type resolution as the workaround for member-chain receivers. Validation: - gitnexus-shared builds clean - gitnexus typecheck clean - 413/413 tests pass under both flag states for finalize-algorithm + TS unit + TS integration suites - 972/972 tests pass across full scope-resolution + Python + C# integration smoke (no cross-language regression) Made-with: Cursor * refactor(finalize): replace recursive followReexportChain with SCC-condensed iterative closure The legacy `followReexportChain` walked re-export drafts via mutual recursion guarded by a per-call visited set + a `MAX_REEXPORT_DEPTH` ceiling. Recursion is fragile (call-stack ceiling, no bound on depth that's actually meaningful), so this replaces it with a structurally better algorithm: a precomputed per-file re-export closure built by running Tarjan SCC over the re-export sub-graph and propagating names in reverse-topological order with a bounded intra-SCC fixpoint. Algorithm (`buildReexportClosures` in finalize-algorithm.ts): 1. Sub-graph: build the directed graph of `reexport` + `wildcard` drafts only (regular/namespace/dynamic imports do not contribute). 2. SCC condensation: run the same iterative `tarjanSccs` already used for the file-level import graph; output is in reverse-topo order so out-of-SCC neighbors are always already-finalized. 3. Per-SCC propagation: - Acyclic singleton: one pass populates from neighbors' closures. - Cyclic SCC: bounded fixpoint capped at |SCC|+1 iterations. With first-wins precedence the closure map is monotone, so each name needs at most |SCC| hops to traverse the cycle. Precedence (preserved from the recursive crawl): - Named re-exports take precedence over wildcards. - Within each kind, declaration order wins. Lookup at finalize time becomes O(1) (`lookupReexportedName`), down from O(chain_depth × drafts) per consult and recursive at that. Properties vs the legacy implementation: - Stack-safe by construction; no `MAX_REEXPORT_DEPTH` guard needed. - 1000-hop barrel chains now resolve in full (legacy capped at 100 and surfaced anything deeper as `unresolved`). - Cycles handled structurally via SCC, not via per-call visited set. - Same observable semantics: every existing test passes unchanged. Tests: - Replace the obsolete `MAX_REEXPORT_DEPTH (200-hop chain stops cleanly without stack overflow)` test (which asserted the OLD bug — that deep chains failed to resolve) with a positive 1000-hop test that asserts full resolution + accurate `transitiveVia`. Proves both the recursion is gone AND the closure correctly inherits the leaf def across all hops. - Update commentary on adjacent re-export tests to reference the closure mechanism. - Update `FinalizeFile.localDefs` JSDoc + import-decomposer.ts inline doc to point at `buildReexportClosures` instead of the removed function name. Validation: - gitnexus-shared builds cleanly. - gitnexus typechecks cleanly. - 28/28 finalize-algorithm.test.ts tests pass (incl. new 1000-hop). - 801/801 TypeScript scope-resolution tests pass under default (registry-primary) AND `REGISTRY_PRIMARY_TYPESCRIPT=0` (legacy DAG). - 404/404 Python + C# integration tests pass — no regression in cross-language consumers of the shared `finalize`.

The existing test/integration/resolvers/python.test.ts (191 tests, driven by runPipelineFromRepo) is the source of truth for Ring 3 parity. Also document the IMPORTS-emission follow-up gap: wiring emitImportEdges in python-scope-emit.ts today regresses 10 IMPORTS-edge fixtures because the scope-extractor's ImportEdge coverage is narrower than legacy pythonImportConfig.importResolver. Tracked as a follow-up. Baseline with REGISTRY_PRIMARY_PYTHON=1 is unchanged: 109/191 pass. * feat(ingestion): scope-resolution phase owns Python IMPORTS edges (RFC #909 Ring 3) When `REGISTRY_PRIMARY_PYTHON=1`, IMPORTS graph edges for Python files are now emitted exclusively by the new scope-resolution path. The legacy `import-processor` still runs — heritage resolution needs its importMap / namedImportMap / moduleAliasMap population — but its graph edge emission is gated per-language so Python no longer double-emits. This closes the reviewer's second change request on PR #980: "the legacy path must be turned off". Legacy IMPORTS edges for Python are now off by default when the flag is enabled. Three bugs were fixed to make the new path's coverage match legacy: 1. **Root-file bailout** (import-resolvers/python.ts): `resolvePythonImportInternal` returned null immediately when the importer file lived at the repo root (importerDir === ''). The ancestor directory walk further down already handles this case correctly; the early return was the bug. Proximity check now only runs when importerDir is non-empty, and the ancestor walk sees root-level files for the first time. 2. **External dotted imports** (languages/python/import-target.ts): the new path fell straight through to `suffixResolve` for multi-segment imports, which happily matched `django.apps` to a local `accounts/apps.py`. Mirror `pythonImportStrategy`'s `hasRepoCandidate` guard — suffix-match only when the leading segment exists somewhere in-repo as a package, __init__.py, or namespace directory. 3. **suffixResolve ambiguity** (languages/python/import-target.ts): the shared `suffixResolve` helper requires a pre-built `SuffixIndex` to disambiguate ties. Without one it falls back to an O(files) scan that silently picks the first match when the last segment collides across directories (e.g. `accounts.models` matching `billing/models.py`). Replaced with `resolveAbsoluteFromFiles` — exact lookup first, then a deterministic suffix match. Validation: - Flag OFF: 191/191 pass (no regression). - Flag ON: 109/191 pass (82 fail — exact baseline match; remaining 82 are unchanged CALLS-edge provider-feature gaps tracked as Phase B follow-ups). - `tsc --noEmit`: clean. The 82 CALLS failures cluster into 44 describe blocks covering type-inference features (assignment chains, walrus, class-level annotations, constructor inference, C3 MRO, overload dispatch, return-type inference) that need dedicated Ring 3 follow-up work. Each cluster is tracked against the RFC #909 shadow-parity gate (>=99% fixtures / >=98% corpus) in the per-language ticket. * ci(scope-resolution): automatic parity gate driven by MIGRATED_LANGUAGES Adds the Ring 3 parity gate the RFC §6.4 requires: when a language's scope-resolution migration is marked complete, CI runs its resolver integration test twice on every PR (once with the legacy DAG, once with the registry-primary path) and both must pass. The "is this language migrated" signal is a single TypeScript constant: // gitnexus/src/core/ingestion/registry-primary-flag.ts export const MIGRATED_LANGUAGES: ReadonlySet<SupportedLanguages> = new Set([ /* SupportedLanguages.Python when ready */ ]); Adding a language here has three simultaneous effects: 1. `isRegistryPrimary(lang)` defaults to true for that language in production (env-var override still wins if set explicitly). 2. `.github/workflows/ci-scope-parity.yml` auto-discovers the set via `npx tsx scripts/ci-list-migrated-languages.ts`, builds a parity matrix, and runs: - `REGISTRY_PRIMARY_<LANG>=0 npx vitest run resolvers/<slug>.test.ts` - `REGISTRY_PRIMARY_<LANG>=1 npx vitest run resolvers/<slug>.test.ts` Both legs must pass for the job to succeed. 3. Legacy-path gating in call-processor.ts / import-processor.ts kicks in automatically through the same `isRegistryPrimary` lookup. No JSON registry, no manual workflow edit, no second source of truth — contributors update the Set and CI picks it up. Empty Set = parity job is a skipped matrix (workflow still reports success). The new `scope-parity` reusable workflow is added to ci.yml's `needs` graph and ci-status gate. Its result must be `success` (skipped would mean upstream discover job failed and should block). Validation (with empty MIGRATED_LANGUAGES set): - flag OFF: 191/191 pass (no behavior change) - flag ON (manual REGISTRY_PRIMARY_PYTHON=1): 82 fails = baseline exact match - `npx tsc --noEmit`: clean - concurrency-convention script: pass - tsx discovery script: emits `[]` correctly * ci(scope-resolution): keep MIGRATED_LANGUAGES empty; fix linter auto-uncomment Previous commit's example entry got auto-uncommented (linter preferred a type-checkable `SupportedLanguages.Python` over a commented-out reference). That would have triggered the parity CI gate against Python, which today has 82 known flag-on failures — unintended and would block the PR. Use the explicit generic `new Set<SupportedLanguages>([])` so an empty set still type-checks without needing an uncommented-out sample member. Example in the comment now has `// SupportedLanguages.Python,` so it remains illustrative without participating in the set. * feat(python): capture constructor-inferred + annotated type bindings Extends the Python scope-extractor with two new type-binding capture patterns so receiver-typed method dispatch has concrete type bindings to work from: 1. `u: User = ...` / `u: User` — variable annotations. `@type-binding.annotation` anchor, `source: 'annotation'`. 2. `u = User("alice")` — assignment RHS is a bare-identifier call (Python has no `new` keyword; constructor-shaped calls are syntactically identical to function calls). `@type-binding.constructor` anchor, `source: 'constructor-inferred'`. The runtime query lives in `query.ts` (the `.scm` file is documentation per the comment at its top); both are updated. Fixes 19 failures across these resolver fixtures (flag-on 82 → 63): - Python constructor-inferred type resolution (3) - Python class-level annotation resolution (3) - Python nullable receiver resolution (3) - Python member-call / receiver-constrained / constructor-call (3) - Python assignment chain propagation (2) - Python walrus / match-case / chained method (3) - Python member access iterable for-loop (2) * feat(python): strip nullable unions + prefer annotations over inference Two linked changes that together fix the 4 nullable-receiver tests: 1. `stripNullable` in Python's `interpretTypeBinding` unwraps `User | None`, `None | User`, and `Optional[User]` to `User`, so receiver-typed resolution treats nullable receivers identically to non-nullable ones. Three-arm unions (`User | Error | None`) are left unchanged — truly ambiguous for single-receiver inference. 2. Source-strength ordering in `pass4CollectTypeBindings`. When multiple matches fire for the same bound name in the same scope — e.g. the `u: User = find()` idiom where both the annotation and constructor-inferred patterns match — the explicit annotation now wins regardless of query-match arrival order. Rank: explicit (annotation / parameter-annotation / return-annotation / self) > inferred Also reorders the two Python patterns in query.ts / scopes.scm so the constructor-inferred pattern appears first — a belt-and-braces fallback that keeps behavior deterministic if the shared priority ranking is ever revisited. Fixes 4 failures (flag-on 63 → 59): - Python nullable receiver resolution (4 tests) Flag-off regression check: 191/191 still pass. * feat(python): walrus, qualified-call, match-case type bindings Extends the constructor-inferred family of captures with three more assignment-shaped patterns that all bind a variable to a class-like type: - Walrus: `(u := User(...))` → `u: User` via `(named_expression)`. - Qualified call RHS: `u = models.User(...)` → `u: models.User` via `(attribute)` node .text. Falls through resolveTypeRef Phase 2 (QualifiedNameIndex dotted fallback). - Match as-pattern: `case User() as u:` → `u: User` via `(as_pattern)` + `(class_pattern (dotted_name))`. Fixes 2 failures (flag-on 59 → 57): - Python walrus operator type inference - Python match/case as-pattern type binding Qualified-call constructor tests still fail because they require cross-module qualifiedName registration (models.User → models.py's User class) which isn't yet wired in the Python extractor. Tracked as follow-up alongside module-import CALLS (#337) resolution. * feat(python): chain type bindings + strip list[T] generic for for-loop Adds two capture patterns and a shared transitive-closure pass that together handle Python's variable-aliasing and for-loop-over-typed- iterable patterns: 1. `(assignment left: (identifier) right: (identifier))` — `alias = u`. 2. `(for_statement left: (identifier) right: (identifier))` — `for u in users`. Both emit `@type-binding.alias` with the RHS identifier as rawName. The shared `pass4CollectTypeBindings` now runs a final transitive-closure walk that follows identifier-chain TypeRefs through the declaring scope and its ancestors (depth-capped, cycle-guarded) so `alias` ultimately points at the class type instead of another local variable name. Generic stripping in `interpret.ts` unwraps single-arg collection wrappers — `list[User]`, `set[User]`, `Iterable[User]`, etc. — to the element type. Multi-arg generics (`dict[str, User]`, `Callable[...]`) are left alone; their semantics aren't unambiguous. Fixes 8 failures (flag-on 57 → 49): - Python assignment chain propagation (4) - Python nullable + assignment chain (2) - Python walrus operator (:=) assignment chain (2) Flag-off still 191/191. * feat(python): namespace & class receiver resolution + file-level caller fallback Adds a Python-specific post-resolution pass `emitReceiverBoundCalls` that closes two receiver gaps the shared `MethodRegistry.lookup` doesn't cover: 1. **Namespace receivers** — `import models; models.User()` / `import models as m; m.User()`. The shared `lookupReceiverType` only walks `scope.typeBindings`; namespace imports never land there (they're filtered out of `scope.bindings` when the target module has no self-named def, per `finalize-algorithm.ts:540`). The new pass walks `indexes.imports` directly, builds a per-file `localName → targetFilePath` map, and emits CALLS/ACCESSES edges against the target file's `localDefs`. 2. **Class-name receivers** — `Dog.classify("dog")`. The shared resolver requires typeBindings; class bindings in `scope.bindings` are never consulted as receivers. The new pass checks class-kind bindings in the call scope's chain and resolves members via `ownerId`. Also fixes module-level call attribution: `resolveCallerGraphId` now falls back to the File node id (`generateId('File', filePath)`) when no enclosing function/method/class is found. Matches legacy DAG behavior for module-scope calls like `u = models.User()` at the top of app.py. Fixes 4 failures (flag-on 49 → 45): - Python module import CALLS resolution (Issue #337) (4 of 7) Flag-off still 191/191. * feat(python): dotted-typebinding receiver resolution Adds case 3 to `emitReceiverBoundCalls`: when a receiver's typeBinding has a dotted rawName like `u: models.User` (the constructor-inferred form fired by `u = models.User(...)`), walk the namespace map + target file's defs to find the class, then look up the member via ownerId. `resolveTypeRef`'s QualifiedNameIndex fallback can't cover this because the target class's qualifiedName in models.py is just `"User"`, not `"models.User"` — the dotted form only exists in the call-site file's receiver expression. This pass bridges that gap without modifying the shared registry. Fixes 9 more failures (flag-on 45 → 36): - Python qualified constructor inference (2) - Python module import CALLS resolution (Issue #337) (3) - (cluster overlap — several downstream tests in assignment/nullable/ walrus that propagate through qualified-ctor bindings also benefit) Flag-off still 191/191. * feat(python): consult finalized bindings for receiver resolution `findClassBindingInScope` now walks BOTH: 1. `scope.bindings` — pre-finalize local declarations (origin: 'local') 2. `indexes.bindings` — post-finalize cross-file imports/namespaces Without (2) we were blind to any class brought in via `from models import Dog` at the call site's file, because the scope-extractor's Pass 2 only populates local bindings and the cross-file finalize produces a separate bindings map that never lands on `scope.bindings`. Case 2 (`Dog.classify()`) now walks MRO so inherited static/class methods resolve — `Dog.classify()` where `classify` lives on `Animal`. Case 4 (simple typeBinding like `u: U` from aliased import) now uses `findClassBindingInScope` instead of the shared `resolveTypeRef`, because `resolveTypeRef`'s `ctx.scopes` only sees pre-finalize local bindings too. Fixes 4 more failures (flag-on 36 → 32): - Python method enrichment > Dog.classify static (1) - Python static/classmethod class-as-receiver (2) - Python alias import resolution (1) Flag-off still 191/191. * refactor(python-scope): extract language-agnostic emit-core/ Unit 1 of the python migration architectural plan (docs/plans/2026-04-19-001-refactor-python-migration-architectural-plan.md). Splits python-scope-emit.ts (~945 → 481 lines) by lifting 14 generic graph-feeding primitives into emit-core/: - graph-node-lookup, graph-id, emit-edge - emit-references, emit-imports - scope-walkers (findReceiverTypeBinding, findClassBindingInScope, findOwnedMember, findExportedDef) - namespace-targets, method-dispatch-bridge Each file carries a "Next-consumer contract" JSDoc so future language migrations (TS #927, JS #928, Java, Kotlin, Ruby) import from emit-core rather than re-implementing. python-scope-emit.ts keeps only the four Python-specific pieces: runPythonScopeResolution (orchestrator), buildPythonMro, emitReceiverBoundCalls (4 cases), populateMethodOwnerIds — these move to languages/python/emit/ in Unit 11. Pure refactor, zero behavior change: - flag-off: 191/191 python.test.ts pass (identical baseline). - flag-on (REGISTRY_PRIMARY_PYTHON=1): 32 fail / 159 pass (identical baseline — the refactor neither fixes nor regresses any test). - tsc --noEmit clean. * feat(python-scope): arity metadata + bind function decls in parent scope Unit 2 of the python migration architectural plan (docs/plans/2026-04-19-001-refactor-python-migration-architectural-plan.md). Two changes that the registry-primary path needs before any of the arity-sensitive failures can move: 1. Arity metadata on scope-extracted Function/Method defs. - New helper `languages/python/arity-metadata.ts` reuses `pythonMethodConfig.extractParameters` so self/cls stripping, defaults, and *args/**kwargs detection match legacy semantics. - `emit-captures.ts` synthesizes `@declaration.parameter-count` / `@declaration.required-parameter-count` / `@declaration.parameter-types` captures on every `@declaration.function` match. - Generic `scope-extractor.ts buildDefFromDeclarationMatch` reads the three optional captures into `SymbolDefinition`. Absence is still the no-op default for non-Python providers. 2. Hoist function/class declaration bindings to the enclosing scope. The "innermost scope containing the anchor" default placed `def greet(...)` inside greet's OWN body — invisible to other module-level callers, so every flag-on free-call resolved to `unresolved`. The hoist condition (`anchor range == innermost range`) only fires for scope-creating declarations, so variable / for-loop captures whose anchor is a child identifier stay put. Hooks can still override via `bindingScopeFor`. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on (REGISTRY_PRIMARY_PYTHON=1): 31 fail / 160 pass (was 32/159; the hoist unblocks free-call resolution end-to-end). - tsc --noEmit clean. Per-(source,target) edge collapse for multi-call-site cases (default-params, variadic) still pending — landing it without regressing the static-method find_user fixture (which expects two distinct edges through different targets) needs the ownership-aware qualified-id work that lands with Unit 4 / Unit 11. * feat(python-scope): capture function return-type annotations Unit 3 of the python migration architectural plan (docs/plans/2026-04-19-001-refactor-python-migration-architectural-plan.md). Wires the `def get_user() -> User` return-type annotation into the typeBindings stream so the existing constructor-inferred + transitive chain machinery can resolve `u = get_user(); u.save()` to `User#save` without any orchestrator change. Changes: - `query.ts` + `scopes.scm`: new `@type-binding.return` pattern keyed by the function name (matches RFC §5.1 canonical vocabulary). - `interpret.ts`: maps `@type-binding.return` to the existing `'return-annotation'` source label (no shared change needed). - `scope-extractor.ts pass4CollectTypeBindings`: extends the Pass 2 auto-hoist (anchor range == innermost scope range → bind in parent) to type bindings as well — return-type bindings whose anchor IS the function_definition land in the function's enclosing scope so callers see them. Same-file return-type inference is now end-to-end: `def get_user() -> User: ...` + `u = get_user()` produces `u: User (return-annotation)` in the caller's scope via `followChainedRef`. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 31 fail / 160 pass (no change — every remaining return-type test in this fixture set is *cross-file*; carrying `get_user → User` across module boundaries lands with the cross-file typeBinding propagation work in Unit 5/7). - tsc --noEmit clean. * feat(python-scope): resolve dotted receivers via class-scope field types Unit 4 partial — the dotted-receiver case (`user.address.save()`). Class-body annotations like `class User: address: Address` already land in the class scope's typeBindings via the existing `@type-binding.annotation` capture. This commit consumes that signal: - Build a `Map<classDefId, Scope>` from every parsed file's class scopes once per resolution pass. - New Case 0 in `emitReceiverBoundCalls`: when the receiver's name contains a dot, walk the chain — resolve the head's type, then for each remaining segment look up that field's type in the owner class's scope.typeBindings, then emit the call against the final class with MRO walk. - Cross-scope lookups use each TypeRef's `declaredAtScope` so an imported `Address` resolves in the file that owns the field declaration, not the file holding the call site. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 29 fail / 162 pass (was 31/160; both `Field type resolution` fixtures now pass — same-file and cross-file disambig). - tsc --noEmit clean. Remaining Unit 4 work (write ACCESSES, `self.X` for-loop iteration) needs Unit 6's tuple/iterable destructuring before it can land — `for u in self.users` requires the iterable typing path. * feat(python-scope): chain receiver via call-expression return types Unit 5 — extends the compound-receiver case to handle call-expression receivers (`svc.get_user().save()`). `resolveCompoundReceiverClass` is the single recursive entry point for all compound receivers. Three shapes: - bare identifier — typeBinding chain - dotted `obj.field[.field]…` — class-scope field types - call `expr.method()` — recurse into expr, look up method's return-type typeBinding on its class scope Method return-type bindings auto-hoist to the parent (class) scope per Unit 3, so `methodClassScope.typeBindings.get(methodName)` is the canonical lookup. Free-call return types (`get_user()`) walk the caller's scope chain. Depth-capped at 4 hops to bound recursion. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 28 fail / 163 pass (was 29/162; `Python chained method call resolution` now passes). - tsc --noEmit clean. Two related tests (`city.save() via method chain`, `c.greet().save() depth-2 MRO`) still fail because the captures yield typeBindings shaped like `city → user.get_city` (no trailing parens — the capture grabs the attribute text). Resolving those needs a follow step that detects the call-shape rawName and feeds it through the compound recurser. Lands with the chain-typeBinding work in a follow-up. * feat(python-scope): free-call fallback consults finalized bindings Unit 7 — closes the cross-file free-call gap. The shared `MethodRegistry.lookup` walks `scope.bindings` (pre-finalize local-only) for free-call resolution. Cross-file imports land in `indexes.bindings` (post-finalize). Without the dual-source lookup, `from x import f; f()` resolves to "unresolved" and no CALLS edge is emitted. Two changes: - `emit-core/scope-walkers.ts`: new `findCallableBindingInScope` — same dual-source pattern as `findClassBindingInScope`, but accepts Function/Method/Constructor. Promoted to emit-core because every language with cross-file imports needs the same lookup. - `python-scope-emit.ts emitFreeCallFallback`: post-pass that walks every free-call reference site, looks up the callee with the new helper, and emits via `tryEmitEdge`. Pre-seeds `seen` from the shared resolver's emissions so we never double-count. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 22 fail / 169 pass (was 28/163; +6 tests including the Python overload dispatch fixtures, ancestor-directory imports, and same-name module-alias collision). - tsc --noEmit clean. * feat(python-scope): super() receiver dispatches up the MRO Unit 8 — `super().method()` inside a class method walks the enclosing class's MRO chain (skipping self) and resolves to the first ancestor that owns the method. New receiver branch in `emitReceiverBoundCalls` recognizes `super(...)` syntactically (regex-cheap), finds the enclosing class via a new `findEnclosingClassDef` scope-walk helper, then re-uses `scopes.methodDispatch.mroFor` + `findOwnedMember` from the existing class-receiver path. Handled before the compound-receiver case so `super()` doesn't fall into the bare-identifier branch where `super` isn't a binding. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 21 fail / 170 pass (was 22/169; `super().save() inside User to BaseModel.save` now passes). - tsc --noEmit clean. * feat(python-scope): suppress shared resolver on member-call sites Unit 9 — `app_metrics.get_metrics()` (namespace import alias) was emitting two CALLS edges: a wrong self-call from the shared resolver's free-call fallback, plus the correct namespace-receiver edge from the Python post-pass. Mechanism: - `emit-core/emit-references.ts`: new optional `skipSites` parameter (`Set<string>` of `${filePath}:${line}:${col}` keys). When supplied, references at those positions are skipped — the provider has already emitted (or chosen not to emit) for that site. - `python-scope-emit.ts`: reorders Phase 4 — receiver-bound + free- call fallback run FIRST, populating `handledSites`. The shared `emitReferencesViaLookup` then runs with that set so the resolver's fallback can't fight a precise per-receiver emission. Site keys are added only on successful tryEmitEdge (not for sites the post-pass saw but couldn't resolve — those still get a chance from the shared path). Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 20 fail / 171 pass (was 21/170; same-name module-alias collision now resolves correctly). - tsc --noEmit clean. * feat(python-scope): propagate return-type bindings across imports Closes the cross-file return-type propagation gap that left tests like `u = get_user(); u.save()` (where get_user lives in another file) with `u` typed as the function name instead of its return type. The shared finalize pass copies callable bindings (`from x import f` puts `f` in the importer's bindings) but typeBindings stay file-local because they live on `Scope.typeBindings`, not on the index. Mutate post-finalize: - For each module-scope import binding (`origin: 'import'` or `'reexport'`), look up the source file's module-scope typeBinding for the def's simple name. If present (return-annotation source), mirror it under the importer's local alias. Skip when the importer already has its own typeBinding for the name (explicit local always wins). - After propagation, re-run a chain-follow on every scope's typeBindings — pass-4 ran before propagation and missed any chain whose terminal lived in a foreign file. Same algorithm as `followChainedRef` in scope-extractor, but operates on the finalized scopes so propagated entries are visible. Mutating `Scope.typeBindings` is safe — `draftToScope` constructs a plain `new Map(...)`, not a frozen one. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 16 fail / 175 pass (was 20/171; +4 — both cross-file return-type tests, plus two related propagation cases). - tsc --noEmit clean. * feat(python-scope): for-loop call-iterable typeBinding Adds `(for_statement left: (identifier) right: (call function: (identifier)))` to the typeBinding capture set. Combined with Unit 3's return-type capture and the cross-file return-type propagation pass, this makes `for u in get_users(): u.save()` resolve to `User.save` even when `get_users` is imported from another module. Captured as `@type-binding.alias` (rawName = function identifier, without parens) so the existing chain-follow walks the alias to the function's return-type binding without any new code path. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 12 fail / 179 pass (was 16/175; +4 for-loop call-iterable tests across get_users / get_repos fixtures). - tsc --noEmit clean. * feat(python-scope): collapse free-call edges per (caller, target) Free calls (no explicit receiver) now emit a single CALLS edge per (caller, target) pair regardless of how many call sites the caller contains. Mirrors the legacy DAG's per-pair dedup contract — what the `default-params`, `variadic`, and `overload` fixtures expect. Member calls keep position-based dedup so distinct resolved targets (e.g. UserService.find_user vs AdminService.find_user from the same caller) still produce distinct edges. Implementation: bypass `tryEmitEdge` (which dedupes positionally) and hand-roll the relationship with a position-independent rel.id (`rel:CALLS:<caller>-><target>`). Site handling is now unconditional — even when the dedup-collapse skips the actual emit, we mark the site handled so the shared `emit-references` doesn't fight us with its fallback. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 10 fail / 181 pass (was 12/179; +2 — both `default parameter arity` tests now pass). - tsc --noEmit clean. * fix(python-scope): match legacy CALLS reason for import-resolved free calls The arity-narrowing test asserts \`rel.reason === 'import-resolved'\` for cross-file free-call edges. Switch the free-call fallback's reason to mirror legacy DAG semantics: - target-file !== source-file → 'import-resolved' - same file → 'local-call' Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 9 fail / 182 pass (was 10/181; +1 arity-narrowing test). - tsc --noEmit clean. * fix(python-scope): drop dead pre-seeding from receiver-bound pass The pre-seeding loop at the top of \`emitReceiverBoundCalls\` populated \`seen\` with every reference the shared resolver had already resolved. That was useful when emit-references ran FIRST. After Unit 9 reversed the order (emit-references runs after the Python passes and uses \`handledSites\` to skip what we processed), the pre-seed only causes harm: when an MRO walk in Case 0 (compound receiver) and Case 4 (simple typeBinding) both touch the same site at the same position but resolve to different targets, the pre-seed suppresses the second emission because the shared resolver had already entered the wrong target into \`seen\`. Concrete case: \`c.greet().save()\` — Case 0 emits the outer save edge to Greeting.save; Case 4 then resolves the inner \`c.greet()\` to A.greet via MRO walk. With pre-seed both edges should emit (different targets, different rel.ids); without removing the pre-seed the inner emission was being deduped against an already-seeded entry and the A.greet edge was lost. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 8 fail / 183 pass (was 9/182; +1 — \`c.greet() to A#greet via MRO walk\` now passes). - tsc --noEmit clean. * feat(python-scope): enumerate(X) for-loop tuple destructuring Adds two new typeBinding capture patterns for the canonical enumerate pattern: for (i, u) in enumerate(users): ... ; tuple_pattern for i, u in enumerate(users): ... ; pattern_list Both bind the second tuple element (u) to the iterable identifier (users). The chain-follow then unwraps users → its element type via the existing generic-strip in interpret.ts (List[User] → User). The #eq? predicate scopes the pattern to enumerate specifically; generic tuple destructuring of arbitrary callables is left to a future iteration once we have a richer signal for "what does this call yield". Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 7 fail / 184 pass (was 8/183; +1 — `parenthesized tuple: for (i, u) in enumerate(users)` now passes). - tsc --noEmit clean. * feat(python-scope): dict.items() value-type unwrapping Two changes that together resolve `for k, v in data.items(): v.save()`: - `interpret.ts stripGeneric`: extends to `dict[K, V]` / `Dict[K, V]` / `Mapping[K, V]` etc., stripping to the value type V. Previously only single-arg generics (list[User] → User) were stripped; multi-arg ones returned the raw text. - `query.ts` + `scopes.scm`: new typeBinding patterns for `for k, v in X.items()` (both pattern_list and tuple_pattern). The second tuple element binds to X; the chain-follow then unwraps X's dict annotation to V via the new stripGeneric branch. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 6 fail / 185 pass (was 7/184; +1 — `dict.items() loop` test now passes). - tsc --noEmit clean. * feat(python-scope): nested tuple destructuring for enumerate(d.items()) Two more for-loop typeBinding patterns: - `for i, (k, v) in enumerate(d.items())` — nested tuple destructuring where v is the value of the dict's items() yield. - `for v in d.values()` — explicit values() form (companion to items). Both bind the loop var to the dict identifier; the chain-follow unwraps via the dict-aware stripGeneric to the value type. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 5 fail / 186 pass (was 6/185; +1 nested tuple test). - tsc --noEmit clean. * feat(python-scope): 3-var flat destructuring for enumerate(d.items()) Adds the \`for i, k, v in enumerate(d.items())\` shape — flat 3-variable destructuring of the (i, (k, v)) tuple yielded by \`enumerate\` over \`items()\`. Binds v (the last identifier in the pattern_list) to the dict identifier; the existing dict-aware stripGeneric unwraps to the value type. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 4 fail / 187 pass (was 5/186; +1). - tsc --noEmit clean. * feat(python-scope): write ACCESSES edges for attribute assignments Three changes that together produce ACCESSES (write) edges for \`obj.field = value\` assignments: - New \`@reference.write.member\` capture in query.ts and scopes.scm matching \`(assignment left: (attribute object: ... attribute: ...))\`. Reuses the existing receiver/name capture shape so the receiver-bound emit pass can resolve obj's class and look up the field. - \`populateMethodOwnerIds\` now sets ownerId on class-body fields too, not only on methods. Previously it only walked Function scopes whose parent was Class; class-body annotations like \`name: str\` live directly in the Class scope's ownedDefs and were missed, so \`findOwnedMember(User, "name")\` returned undefined. - \`emit-core isLinkableLabel\` extends to Variable and Property so field nodes appear in the graph-node lookup (the legacy parser emits both kinds for class-body annotations). - Case 4 in receiver-bound pass now uses the kind word as the edge reason for read/write sites — matches the legacy DAG convention the test asserts on. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 3 fail / 188 pass (was 4/187; +1 — write-ACCESSES test). - tsc --noEmit clean. * feat(python-scope): chain-typebinding + field-fallback method lookup Reaches the architectural-plan target of >= 189/191 flag-on passing. Two intertwined changes: - Field-fallback in resolveCompoundReceiverClass: when method lookup on the receiver's class (and its MRO) fails, walk the class's fields and try the same lookup on each field's type. Matches the "unified fixpoint" intent of the method-chain fixture where `user.get_city()` reaches `Address.get_city` through User's `address: Address` field. - New Case 3b in receiver-bound emit pass: when the receiver's typeBinding rawName has a dot but isn't a namespace prefix (e.g. `city -> user.get_city` from the constructor-inferred capture for `city = user.get_city()`), treat it as a method-call chain and pipe through the compound resolver. The chain unwraps to the terminal class (City) and the call resolves normally. Verification: - Flag-off: 191/191 (identical baseline). - Flag-on: 2 fail / 189 pass (was 3/188; +1 city.save method chain). - tsc --noEmit clean. Remaining 2 failures are fixture-driven (self.users / self.repos fixtures reference fields that aren't declared on the class) and documented as known-limitation in Unit 10. * feat(python-scope): flip Python to registry-primary (191/191 parity) Adds the \`for u in self.X\` heuristic typeBinding capture (binds u to the attribute name X so the chain-follow can resolve via the enclosing method's parameter typeBinding) — closes the last two failing fixtures whose classes reference \`self.X\` for fields that are actually method parameters. With 191/191 passing on BOTH legacy and registry-primary paths, flips \`MIGRATED_LANGUAGES\` to include \`SupportedLanguages.Python\`. Effects: - Production default for Python files: registry-primary path. - CI parity gate auto-discovers Python via the script + workflow (\`scripts/ci-list-migrated-languages.ts\` / \`.github/workflows/ci-scope-parity.yml\`) and runs the resolver integration test BOTH ways on every PR. - Operators retain the \`REGISTRY_PRIMARY_PYTHON=0\` escape hatch. Verification: - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - Default (unset, post-flip): 191/191 (uses registry). - tsc --noEmit clean. This concludes RFC #909 Ring 3 — Python migration. * refactor(emit-core): EmitProvider interface + promote 5 generic helpers G-Units 1-2 of the emit-pipeline generalization plan. Adds: - emit-core/emit-provider.ts — typed EmitProvider contract (6 required + 2 optional fields). Will be consumed by the generic orchestrator in G-Unit 6. Documents the LanguageProvider vs EmitProvider boundary. - emit-core/emit-free-call.ts — emitFreeCallFallback promoted as-is (drops the unused referenceIndex pre-seed parameter; underscore-prefixed to keep the signature compatible). - emit-core/propagate-return-types.ts — propagateImportedReturnTypes + followChainPostFinalize. Documents the mutation contract (Invariant I3 + I6 from the plan): runs after finalize, before resolve, mutates the non-frozen Scope.typeBindings map. - emit-core/scope-walkers.ts: + findEnclosingClassDef + findExportedDefByName. Both were already generic in the Python source. python-scope-emit.ts shrinks 1055 → 799 lines (–256). Imports the promoted helpers from emit-core. No behavior change. Verification: - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - tsc --noEmit clean. * refactor(emit-core): promote receiver-bound dispatcher + compound resolver G-Unit 3 of the emit-pipeline generalization plan. - emit-core/emit-compound-receiver.ts — resolveCompoundReceiverClass + matchingOpenParen + COMPOUND_RECEIVER_MAX_DEPTH. Field-fallback is now an option (default true) so strictly-typed languages can opt out via EmitProvider.fieldFallbackOnMethodLookup. - emit-core/emit-receiver-bound.ts — the 7-case dispatcher (super, Cases 0/1/2/3/3b/4). Accepts a ReceiverBoundProviderSubset (isSuperReceiver + fieldFallbackOnMethodLookup) so partial wiring works during the rest of the migration. Documents Contract Invariants I4 (case order) and I5 (no pre-seeding). python-scope-emit.ts shrinks 799 → 384 lines. The orchestrator now calls the generic emitReceiverBoundCalls with an inline minimal provider (pythonEmitProviderInline) — full provider lands in G-Unit 6 when the orchestrator itself moves to languages/python/emit/. Verification: - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - tsc --noEmit clean. * refactor(emit-core): promote MRO walk + populateClassOwnedMembers G-Units 4-5 of the emit-pipeline generalization plan. - emit-core/build-mro.ts — generic buildMro takes a LinearizeStrategy hook receiving (classDefId, directParents, parentsByDefId). Three shared steps (collect EXTENDS, build defId-by-graphId, walk per class) + parametric linearization. Default strategy is BFS-with- visited (Python's depth-first first-seen, also correct for single-inheritance languages). - emit-core/scope-walkers.ts: + populateClassOwnedMembers — generic OO ownership rule (methods + class-body fields). Both rules ship together because every OO language migrated so far (Python; planned TS/JS/Java/Kotlin) wants both. Languages that need different rules can compose with this as a base step. python-scope-emit.ts shrinks 384 → 255 lines. Verification: - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - tsc --noEmit clean. * refactor(scope-resolution): generic orchestrator + language-agnostic phase G-Units 6-7 of the emit-pipeline generalization plan, plus the pipeline-phase generalization (the user's observation that the phase itself is generic once the orchestrator is). Changes: - emit-core/orchestrator.ts — runScopeResolution(input, provider). The 180 lines of pipeline glue moved here, parametrized by EmitProvider. Provider supplies LanguageProvider, importEdgeReason, and the 6 emit-side hooks. - emit-core/emit-provider.ts — EmitProvider gains languageProvider and importEdgeReason fields so the orchestrator needs nothing else. resolveImportTarget now takes (targetRaw, fromFile, allFilePaths). - languages/python/emit/index.ts — pythonEmitProvider + thin runPythonScopeResolution wrapper. The first reference impl every next-language migration copies. - emit-providers-registry.ts (NEW) — registry of per-language EmitProviders keyed by SupportedLanguages. Adding a language is one line here + the provider file. - pipeline-phases/scope-resolution.ts (NEW) — language-agnostic phase iterating EMIT_PROVIDERS ∩ MIGRATED_LANGUAGES. Replaces pipeline-phases/python-scope.ts (deleted). - python-scope-emit.ts deleted. - pipeline.ts swaps pythonScopePhase → scopeResolutionPhase. The next language migration is now: implement EmitProvider, register it, add to MIGRATED_LANGUAGES. No new pipeline phase, no orchestrator copy-paste. The Python migration's 700+ lines of glue collapse to ~80 lines per future language. Verification: - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - Default (post MIGRATED_LANGUAGES flip): 191/191. - tsc --noEmit clean. * docs(emit-provider): migration cookbook for next-language porters * refactor(scope-resolution): rename emit-core/ → scope-resolution/, EmitProvider → ScopeResolver Reorganizes the registry-primary resolution layer for clarity and contributor onboarding. Driven by feedback that "emit" was triple- overloaded (graph-edge emission + tree-sitter capture extraction + the provider name itself), and the flat 16-file emit-core/ folder mixed five concerns. External research (rust-analyzer hir-def/nameres, Pyright analyzer/, TypeScript binder/checker, Roslyn Binder, IntelliJ Resolver, swc semantic/, biome semantic/, semgrep naming/, JDT Binding, clangd Sema) consistently uses **the phase name** for this layer, never an output verb. "Scope resolution" matches our pipeline-phase name, the plan, and the RFC. ## Folder rename emit-core/ → scope-resolution/ ├── (16 flat files) → ├── contract/scope-resolver.ts ├── pipeline/{run,registry,phase}.ts ├── passes/{receiver-bound-calls, │ free-call-fallback, │ compound-receiver, │ imported-return-types, │ mro}.ts ├── graph-bridge/{node-lookup,ids, │ edges,references-to-edges, │ imports-to-edges, │ method-dispatch}.ts └── scope/{walkers,namespace-targets}.ts Each subfolder maps to one concern a new contributor needs to find: *the contract I implement / the runner that calls me / the helpers I reuse / the graph layer I shouldn't touch / the scope walkers*. ## Symbol renames EmitProvider → ScopeResolver pythonEmitProvider → pythonScopeResolver runPythonScopeResolution → resolvePythonScope EMIT_PROVIDERS → SCOPE_RESOLVERS getEmitProvider → getScopeResolver RunPythonScopeResolution{Input,Stats} → ResolvePythonScope{Input,Stats} ## File renames (per-language) languages/python/emit/index.ts → languages/python/scope-resolver.ts languages/python/emit-captures.ts → languages/python/captures.ts (kills the parse-side "emit" collision) ## Mechanics - Used `git mv` for all files so blame history is preserved. - Updated ~30 import lines across 18 files plus the pipeline-phases barrel and pipeline.ts. - Updated JSDoc cross-references throughout to match the new vocabulary.

Migration cookbook in `scope-resolution/contract/scope-resolver.ts` JSDoc points the next-language porter at all the new names and folder locations. * docs(scope-resolution): finalize phase JSDoc + drop python emoji from generic log line * perf(scope-resolution): O(1) workspace lookup index Introduces `WorkspaceResolutionIndex` — a precomputed bundle of lookup tables built ONCE per resolution run, after `populateOwners` and after finalize, before any pass that needs to find members, exported defs, or class scopes by id. What it replaces (all are pre-existing O(N×D) linear scans of parsedFiles, called inside the receiver-bound MRO chain): - `findOwnedMember(ownerId, name, parsedFiles)` → `Map.get` via `index.memberByOwner.get(ownerId)?.get(name)`. Was the worst offender — receiver-bound dispatcher calls this O(sites × MRO depth) times. - `findExportedDef(filePath, name, parsedFiles)` → `Map.get` via `index.defsByFileAndName`. Hot for namespace-receiver case. - `findExportedDefByName` workspace-wide fallback scan → `Map.get` via `index.callablesBySimpleName`. - `classScopeByDefId` (rebuilt inside `emitReceiverBoundCalls` on every invocation) — moved to one-shot build during finalize, read from `index.classScopeByDefId` everywhere. - `moduleScopeByFile` (rebuilt inside `propagateImportedReturnTypes` on every invocation) — read from `index.moduleScopeByFile`. Findings from a synthetic 100-file Python workload (60 model files each defining 5 classes × 3 methods + 40 user files calling them heavily): scope-resolution wall time: 764ms → 710ms (median, 5 iters) That's a ~7% in-layer win. The smaller-than-expected gain was informative: profiling the synthetic workload shows scope-resolution breakdown is `extract=62% resolve=30% emit=4%`; the index touched the 4% slice (emit + walker calls inside it). Larger O(D) per owner classes will benefit more. Profiling the FULL pipeline (49 fixtures × 3 iters) shows scope-resolution accounts for ~1% of pipeline wall time — the remaining 99% is parse (tree-sitter), heritage, ORM, MRO, processes, and DB writes. So further optimization of this specific layer has marginal pipeline impact; the next-biggest wins live in those phases. Documented as the "double-parse" finding in the audit (captures.ts re-parses each Python file even though the parse phase already produced a tree-sitter Tree) — that's a separate plumbing project across phase boundaries. Bonus: opt-in PROF_SCOPE_RESOLUTION=1 env var prints a per-phase ms breakdown to stderr, so future perf work can measure without extra code changes. Verification: - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - tsc --noEmit clean. * perf(parse/heritage/mro): typed graph iterator + cross-phase tree cache Two structural perf wins targeting the parse / heritage / MRO layers, identified by the post-WorkspaceResolutionIndex profiling (scope-resolution = ~1% of pipeline; the bulk lives upstream). ## 1. KnowledgeGraph.iterRelationshipsByType (PHM-Units 1-2) - Adds a per-type `Map<RelationshipType, Map<id, Relationship>>` index inside `createKnowledgeGraph`, maintained on add / remove / removeNode / removeNodesByFile. - New `iterRelationshipsByType(type)` returns a typed iterator that yields only the requested type. Backwards-compatible: existing `iterRelationships()` / `forEachRelationship()` callers untouched. - Migrated two MRO call sites: - `mro-processor.ts buildAdjacency`: split the single `forEachRelationship` (which scanned every edge in the graph and type-filtered per-iteration) into three typed iterations (EXTENDS, IMPLEMENTS, HAS_METHOD). - `scope-resolution/passes/mro.ts buildMro`: replaced `for (const rel of graph.iterRelationships()) if (rel.type !== 'EXTENDS') continue` with `for (const rel of graph.iterRelationshipsByType('EXTENDS'))`. - Heritage-processor (PHM-Unit 3) was a no-op: it only WRITES EXTENDS/IMPLEMENTS edges, never re-reads. Index is still useful for the seven other graph-iter consumers (community-processor, csv-generator, wildcard-synthesis, process-processor, etc.) — those follow-ups can switch to the typed iterator without touching the graph layer. - Adds 5 unit tests for the new method (add/remove/dedupe semantics, empty-type fresh iterator, removeNode index sync). ## 2. Cross-phase tree cache (PHM-Units 4-5) The audit's #2 finding: Python files are parsed by tree-sitter once in the parse phase, then re-parsed inside scope-resolution's `captures.ts`. Eliminate the second parse by sharing the Tree across phases. - `parse-impl.ts` now maintains TWO ASTCaches with distinct lifetimes: - `astCache` (chunk-local, cleared between chunks) — unchanged; used by call/heritage/import processors during parse. - `scopeTreeCache` (total-parseable-sized, never cleared) — new, exposed via `ParseOutput.astCache` for cross-phase consumption. - `parsing-processor.ts` writes every sequentially-parsed Tree to BOTH caches. Worker-mode parses skip the persistent cache too (Trees can't cross MessageChannels). - `LanguageProvider.emitScopeCaptures` gains an optional `cachedTree` parameter (typed `unknown` to keep the tree-sitter dep out of the contract). - `captures.ts` short-circuits its own `parser.parse(sourceText)` when a cached Tree is supplied. Cache miss falls back to a fresh parse — same correctness path as before. - `runScopeResolution` accepts an optional `treeCache` and forwards per-file `cachedTree` to `extractParsedFile`. - `scope-resolution/pipeline/phase.ts` reads `getPhaseOutput<{astCache}>(deps, 'parse')` and passes through. Verified end-to-end: a small fixture run with PROF_SCOPE_RESOLUTION=1 shows 6/6 cache hits (100% hit rate) on the python-grandparent fixture that exercises the full pipeline below the worker-pool threshold. ## Verification - REGISTRY_PRIMARY_PYTHON=0 (legacy): 191/191. - REGISTRY_PRIMARY_PYTHON=1 (registry): 191/191. - New graph.test.ts: 25/25 (was 20). - tsc --noEmit clean. ## Where the win lands Wall-clock on the 49-fixture integration suite: 14050ms → 14080ms (within noise). Fixtures are 1-3 files each, dominated by per-fixture pipeline overhead (worker-pool init, DB writes, fixture startup). The cache + typed-iterator wins are constant-factor improvements that scale linearly with workload size and visible only on larger repos. The dev-mode `PROF_SCOPE_RESOLUTION` instrumentation + `getPythonCaptureCacheStats()` are kept for future perf work. ## Plan docs/plans/2026-04-20-002-perf-parse-heritage-mro-plan.md. PHM-Unit 3 (heritage-processor migration) intentionally collapsed to a no-op — heritage only writes, never re-reads. * perf(scope-resolution): bound tree-cache lifetime + gate population Address P1 residuals from ce:review of 8c6f5cee: - Dispose scopeTreeCache at end of scopeResolutionPhase via astCache.clear(). Trees were previously retained for the full pipeline (10-100x memory regression on large repos). Downstream phases (mro, community, csv-generator) never read them. - Gate scopeTreeCache.set on provider.emitScopeCaptures !== undefined. Polyglot repos no longer retain Trees for languages with no scope-resolution consumer. - PROF_SCOPE_RESOLUTION=1 now warns when workers engage, since Trees can't cross MessageChannels so the cache will be empty for worker-parsed files — prevents a silent perf cliff once a repo crosses the worker-pool threshold. Tests: 26/26 graph unit, 299/299 scope-resolution unit, 191/191 python integration both flag paths. * refactor(scope-resolution): clean up P2/P3 review residuals P2: - WASM dual-ownership invariant documented on ASTCache dispose: a Tree must live in AT MOST ONE disposing ASTCache. Native tree-sitter today is unaffected; WASM adoption would require tree.copy() or a non-disposing secondary cache. - mro-processor C3 ordering test: pins EXTENDS-before-IMPLEMENTS parent grouping for classes with interleaved edge additions. Asserts exact MRO ['Base', 'Iface'] — a revert to single-loop insertion-order iteration would produce ['Iface', 'Base'] and fail loudly. - cached-tree parity test: emitPythonScopeCaptures(src, path, T) returns identical CaptureMatch[] to emitPythonScopeCaptures(src, path). Pins the cache-hit path's correctness so a regression that silently returns stale captures would break the test. P3: - Dev-mode cache counters moved from captures.ts to cache-stats.ts. Production hot-path module no longer carries the module-global export surface; PROF gating behavior preserved. - ParseOutput field rename astCache → scopeTreeCache. Clarifies that the surfaced cache is the persistent cross-phase one, not the chunk-local astCache parse-impl clears between chunks. Single consumer (scopeResolutionPhase) updated; no other readers. - ASTCacheReader interface extracted. scopeResolutionPhase now reads the phase dep via a shared type instead of a hand-rolled inline structural shape that could drift from ASTCache's contract. - graph.ts dual-index invariant enforced through writeRel/deleteRel private helpers instead of duplicated add/delete at 3 mutation sites. Adding a new mutation method only needs to call the helpers — forgetting to update one index becomes structurally impossible. Tests: 382/382 unit (incl. 2 new), 191/191 python integration both flag paths. tsc clean. * fix(ci): prettier formatting + Python-migration test adjustments CI run 24666612657 failed on three jobs. Fixes: quality/format: - Prettier --check flagged 3 files after the accumulated branch work. Ran prettier --write from repo root (CI's invocation cwd) to apply: simple-hooks.ts, resolve-references.ts, python-hooks.test.ts. tests/{ubuntu,macos,windows} — 9 assertion failures, all traceable to Python landing in MIGRATED_LANGUAGES (default-on registry-primary): - registry-primary-flag.test.ts (3 tests): the 'returns false by default' / 'primaryLanguages empty' / 'Python mid-process mutation' assertions were written in Ring 2 when MIGRATED_LANGUAGES was empty. Rewrote to assert MIGRATED_LANGUAGES membership is the default, use Java (unmigrated) for the no-stale-cache test, and verify env overrides work in both directions (migrated-off, unmigrated-on). - call-processor.test.ts (6 tests in SM-10 + D2-widen blocks): these exercise the LEGACY call-resolution DAG on .py fixtures. processCalls now gates Python out (isRegistryPrimary === true by default), returning 0 edges. Added REGISTRY_PRIMARY_PYTHON=false override in the relevant beforeEach + restore in afterEach, so the legacy DAG runs for these test-local fixtures without affecting the production-default behavior. Local verification: 4126/4126 unit tests pass, prettier clean. * docs(python): known-limitation block on scope-resolution public API Unit 10 — document what the Python registry-primary path intentionally does not resolve, so reviewers and future maintainers can distinguish conscious trade-offs from latent bugs: - Dynamic attribute access (getattr / setattr) - Dynamic imports (importlib, __import__) - Metaclass-driven dispatch - Union / Optional branch-picking behavior - Arbitrary signature-rewriting decorators - typing.TYPE_CHECKING-guarded imports - *args / **kwargs type flow-through - super() outside a directly-bound method Each item names the file that owns the relevant hook so a future follow-up knows where to start. Shadow-harness corpus parity + the CI parity gate remain the authoritative signal for which of these matter at fleet scale. * docs: record scope-resolution pipeline alongside legacy call DAG Capture what shipped in #980 so future readers don't have to reverse- engineer the coexistence of the legacy call-resolution DAG and the new scope-resolution pipeline: - ARCHITECTURE.md: new 'Scope-Resolution Pipeline' section after the Call-Resolution DAG, documenting pipeline stages, ScopeResolver contract, per-language registration, code references, and perf notes. Coexistence block added to the legacy DAG section explaining how MIGRATED_LANGUAGES gates the two paths per-language. - AGENTS.md: reference-docs pointer updated — legacy-DAG one-liner stays; scope-resolution pipeline gets its own pointer so agents know when to read which section. Changelog bumped. - type-resolution-system.md: callout at the 'call-processor.ts is the consumer' claim pointing readers to the scope-resolution path for migrated languages. TypeEnv is still built per file, but for migrated languages receiver typing flows through ParsedTypeBinding rather than call-processor.ts. CHANGELOG.md intentionally not touched — owned by the release process. * chore: remove obsolete scheduled_tasks.lock file * fix(scope-resolution): qualified-name keys for same-file method collisions Review feedback from PR #980 reviewer flagged a BLOCKING correctness bug: when two classes in the same file define a method with the same simple name (e.g. class User: def save + class Document: def save), every d.save() CALLS edge silently resolved to User.save because the graph node lookup keyed only by (filePath, simpleName) and first-wins took User's method. Three-layer fix: 1. populateClassOwnedMembers now promotes a nested def's qualifiedName from `save` to `ClassName.save` when the def sits inside a class scope. Python's scopes.scm doesn't emit @declaration.qualified_name for methods, so without this the finalized SymbolDefinition carried only the simple name. 2. buildGraphNodeLookup adds a second key per node: (filePath, qualifiedName). For Method/Function nodes the qualifier is parsed deterministically out of the node id (`Method:file.py:User.save#N` → `User.save`), which is robust to Windows-style filePath colons. Simple-name key retained as a fallback for callers that don't know the qualifier. 3. resolveDefGraphId now tries the qualified key first, then falls back to the simple-name lookup. Also addresses the non-blocking review items: - scopeResolutionPhase.deps now includes `crossFile` so the Kahn's runner can't schedule scope-resolution before crossFile finishes writing heritage edges that buildMro consumes. - run.ts no longer mutates the finalized ScopeResolutionIndexes via `as` cast — spreads into a fresh object with the populated methodDispatch field instead. - Doc nits: scope-resolver.ts registry path + phase.ts Ring number. Test coverage: - New fixture test/fixtures/lang-resolution/python-same-file-method-collision with User.save + Document.save in one file and app.py calling both through typed receivers. - Three new integration assertions pin that u.save() and d.save() target the correct qualified node id. Fail before the fix, pass after. Confirmed by running once without populateClassOwnedMembers qualifier promotion — reproduces the original User.save-for-both bug. Verification: 194/194 test/integration/resolvers/python.test.ts pass both REGISTRY_PRIMARY_PYTHON=0 and =1. 523/523 related unit tests. tsc --noEmit clean. * fix(scope-resolution): filter export index to module-level defs + label-prefixed qualified key Codex adversarial review on PR #980 flagged that buildWorkspaceResolutionIndex feeds defsByFileAndName and callablesBySimpleName from parsed.localDefs — the flat set of every def in the file including methods, fields, and nested functions. findExportedDef / findExportedDefByName treat those maps as file-level exports, so `mod.save()` could silently bind to User.save whenever a method's simple name appeared first in parse order. Plan: docs/plans/2026-04-21-001-fix-workspace-index-module-scope-only-plan.md Fix layers: 1. workspace-index.ts: split the single parsed.localDefs loop into two passes: - Module-export pass: iterate moduleScope.ownedDefs PLUS ownedDefs of every child scope whose parent is the module scope. Top-level class and function declarations each live in their own scope with parent=module, not in moduleScope.ownedDefs directly, so the "parent === moduleScope.id" walk is required to reach them. Methods (scope.parent === Class scope) and nested functions (scope.parent === another Function scope) are excluded. - Member-by-owner pass: keeps iterating parsed.localDefs since that map is keyed on ownerId and correctly saw class-owned defs before this change. 2. graph-bridge/node-lookup.ts: qualified keys now live in a separate keyspace (`<q>:filePath::<label>::<qualifiedName>`) and include the node label. Without the label prefix, a top-level `def save` (Function, qualifier `save`) would collide with a class method `User.save` (Method, simple name `save`) in the same simple-key slot because the Function's qualifier happens to equal the Method's simple name. The label differentiates them. 3. graph-bridge/ids.ts: resolveDefGraphId uses the new type-prefixed qualified key when def.type is set. Simple-name fallback retained for languages that don't yet synthesize qualifiers on their defs. Test fixture: python-module-export-vs-method-collision places `class User: def save` BEFORE top-level `def save` — parse order that exposes the bug (class method enters the index first). Three new integration assertions: - `mod.save(x)` resolves to the module-level Function, not User.save - `u.save()` resolves to User.save Method - Exactly two CALLS edges to `save` exist, one per intended target Fixture confirmed failing before the workspace-index fix (bug reproduced), passing after. Verification: 197/197 test/integration/resolvers/python.test.ts pass both REGISTRY_PRIMARY_PYTHON=0 and =1. 523/523 related unit tests. tsc --noEmit clean. * fix(scope-resolution): drive module export index from moduleScope.bindings Codex round-2 adversarial review flagged that the workspace-index module-export pass iterated every def in every direct-child scope of the module, including class-body Variable defs like `class User: MAX_USERS = 100`. `defsByFileAndName[file][MAX_USERS]` silently aliased to the class attribute. Latent today because Python doesn't emit ACCESSES edges for `mod.NAME` member access, but the index-layer leak would surface the moment reference capture widens. Plan: docs/plans/2026-04-21-002-fix-codex-round2-scope-resolution-plan.md Drive the module-export index from the extractor invariant instead of a scope-kind → allowed-label switch: moduleScope.bindings already contains exactly the names visible at module level — top-level class/function declarations, module-level variable assignments, imports. Class methods, class-body attributes, and nested-function defs bind to their containing (Class or Function) scope, not the module, so they're naturally excluded. Filter to `BindingRef.origin === 'local'` so imports and wildcard re-exports stay out of the index (matches the pre-fix invariant when the source was `parsed.localDefs`). No per-kind predicates, no scope-kind / def-kind enumeration, no two-pass merge between moduleScope.ownedDefs and direct-child scope walks — one loop, language-agnostic. Codex also flagged `propagateImportedReturnTypes` as potentially broken for function-local imports, but scope-dump probing showed the finalize algorithm puts `from svc import get_user` into the MODULE scope's finalized bindings even when declared inside a function, so the existing module-scope propagation already handles the case. The new python-function-local-import-chain integration test pins that working behavior as a regression guard; no code change required. Coverage: - test/unit/scope-resolution/workspace-index.test.ts (new, 5 tests) — directly asserts the index shape. The "excludes class-body Variable defs" test fails without this fix and passes after (confirmed via stash-pop probe). - test/integration/resolvers/python.test.ts — 4 new integration assertions across two describe blocks (python-class-attr-export-leak, python-function-local-import-chain) pin end-to-end invariants. - Two new fixtures under test/fixtures/lang-resolution/. Verification: 201/201 test/integration/resolvers/python.test.ts both REGISTRY_PRIMARY_PYTHON=0 and =1. 528/528 related unit tests (was 523). tsc clean. * test(scope-resolution): pin local-namespace-import behavior + document empirical finalize hoisting Codex round-3 adversarial review raised three concerns about scope-resolution passes assuming module-scope semantics that would contradict `pythonImportOwningScope`'s documented per-scope contract. Empirical verification via scope-dump probes resolved each: Plan: docs/plans/2026-04-21-003-fix-codex-round3-scope-aware-resolution-plan.md 1. Function- and class-local namespace imports: VERIFIED WORKING. `def outer(): import svc as s; s.call()` and `class A: import mod; def use(self): mod.helper()` both emit CALLS edges with reason "scope-resolution: namespace-receiver". finalize-algorithm hoists the ImportEdges onto `indexes.imports[moduleScope]` regardless of where the `import` statement appears, so collectNamespaceTargets' module-scope read finds them. 2. Imported return-type propagation module-scope-only: VERIFIED WORKING (already pinned in round 2). `from svc import get_user` inside a function body lands in indexes.bindings[moduleScope], so propagateImportedReturnTypes' module-scope read still finds it. 3. Nested method-local defs stamped as class members: VERIFIED FALSE. The scope extractor creates nested Function scopes for inner `def`s; `def helper` inside `def save` inside `class User` lives in helper's own Function scope whose parent is save's Function scope (NOT the Class scope). populateClassOwnedMembers' `parentScope.kind === 'Class'` branch correctly skips it; helper.ownerId stays undefined. Instead of implementing speculative scope-aware refactors that the tests would pass regardless, this commit: - Adds regression fixtures and integration assertions that pin each working behavior. If finalize routing ever changes to honor the hook's per-scope contract, these assertions flip red and signal the need for the scope-chain-aware refactor. - Adds defensive JSDoc to the three flagged call sites (collectNamespaceTargets, propagateImportedReturnTypes, populateClassOwnedMembers) documenting the empirical invariant so future reviewers don't re-derive Codex's theoretical concern without the benefit of the probe. Files: - Two new fixtures under test/fixtures/lang-resolution/ covering the function-local and class-body namespace-import patterns. - Two new describe blocks in test/integration/resolvers/python.test.ts (3 assertions, positive-pin intent). - Defensive comments in namespace-targets.ts, imported-return-types.ts, and scope-resolution/scope/walkers.ts. Verification: 204/204 test/integration/resolvers/python.test.ts both REGISTRY_PRIMARY_PYTHON=0 and =1. tsc clean. * perf(graph): reverse-adjacency + file indexes drop removeNode/removeNodesByFile from O(N) PR #980 in-line review flagged that `removeNode` iterated the full relationshipMap to find edges touching a node (O(E)), and `removeNodesByFile` called removeNode for every matching node after a full nodeMap scan (O(N × E)). Pre-existing, but worth fixing properly since the writeRel/deleteRel helpers we just added make the index-maintenance story coherent. Two new indexes maintained on every mutation path: - `edgeIdsByNode: Map<nodeId, Set<relId>>` — reverse adjacency. Every edge records both endpoints, so removeNode iterates edgeIdsByNode.get(id) instead of every relationship. Self-edges skip the duplicate-endpoint write to keep the Set dedup explicit. - `nodeIdsByFile: Map<filePath, Set<nodeId>>` — file index. removeNodesByFile reaches its file's nodes directly. Complexity: - removeNode: O(edges-touching-node), was O(total-edges). - removeNodesByFile: O(file-nodes × avg-edges-per-node + scan of the file bucket), was O(total-nodes + file-nodes × total-edges). Index maintenance is centralized in writeRel/deleteRel + new addToBucket/removeFromBucket helpers. Empty buckets are pruned to keep the indexes compact. Existing dual-invariant (relationshipMap ↔ relationshipsByType) preserved. Nodes without a `filePath` property (e.g. Community/Cluster nodes) are intentionally NOT indexed in nodeIdsByFile — they can't belong to any file, so removeNodesByFile correctly leaves them alone. Coverage: 7 new unit tests (33/33 total, was 26). Added cases: - removes only edges touching the removed node - handles self-edges - removes orphan node with no edges - removeNodesByFile removes only matching nodes - returns 0 when no match - also removes edges whose endpoints lived on the removed file - does not index nodes without a filePath property Verification: 204/204 test/integration/resolvers/python.test.ts both REGISTRY_PRIMARY_PYTHON=0 and =1. 4235/4235 unit tests. tsc clean. * refactor(ingestion): merge python/ast-utils into utils/ast-helpers; iterative findNodeAtRange python/ast-utils.ts held three language-agnostic helpers (nodeToCapture, syntheticCapture, findNodeAtRange) plus two duplicates of the shared utils version (findChildOfType == findChild; findIdentifierChild was unused). Consolidating into utils/ast-helpers.ts so the next language migrating to the scope-resolution pipeline imports from one place. findNodeAtRange rewritten iteratively using an explicit stack. Previous implementation was recursive — fine for shallow Python trees today, but a landmine for languages with deeper nesting (Kotlin sealed-hierarchy decomposition, Rust macro expansion, etc.) and the task hooks explicitly call out "no recursion". Children are pushed reverse-index so LIFO pop visits them left-to-right; row-bound pruning preserves the prior early-skip optimization (the `break` shortcut is replaced with `continue` since a stack can't leverage ordered sibling termination). findChildOfType consumers migrated to the existing findChild helper. findIdentifierChild deleted — no callers remained. Coverage: 204/204 test/integration/resolvers/python.test.ts both REGISTRY_PRIMARY_PYTHON=0 and =1. 339/339 scope-resolution + graph unit tests. tsc clean. * refactor(scope-resolution): remove unused shouldShadow / shouldCreateScope hooks Both LanguageProvider hooks were dead weight: - `shouldShadow` had zero call sites — the interface declared it, Python implemented a trivial always-true no-op, but no consumer ever read it. The shadowing decision lives in pythonMergeBindings and the central merge algorithm, not in a per-scope predicate. - `shouldCreateScope` had one call site in pass1BuildScopes but the only language implementing it (Python) always returned true. No producer ever emits a `@scope.block` for Python, so the hook's "declines to create" branch was unreachable. Other languages didn't implement it at all. Removing both: - Drops the interface declarations in language-provider.ts. - Drops `shouldCreateScope` from ScopeExtractorHooks Pick and from the pass1BuildScopes conditional — the stack-based parent-resolve loop becomes unconditional. - Drops pythonShouldShadow / pythonShouldCreateScope from simple-hooks, the Python index barrel, and the python.ts provider wiring. - Drops the tests that exercised the removed hooks: one block- suppression scenario in scope-extractor.test.ts, one shouldCreateScope test in parse-worker-scope-integration.test.ts, and the pythonShouldShadow / pythonShouldCreateScope always-true assertions in python-hooks.test.ts. pythonBindingScopeFor's delegate-to-default test is preserved in its own describe block. Shadowing itself is unchanged: pythonMergeBindings still runs, LEGB ordering still applies, wildcard transparency is still handled via the merge precedence rules. The hook API just no longer has a vestigial per-scope toggle we decided not to use. Verification: 204/204 test/integration/resolvers/python.test.ts both REGISTRY_PRIMARY_PYTHON=0 and =1. 335/335 scope-resolution + graph unit tests (was 339, net -4 after removing the hook-specific assertions). tsc clean. * refactor(scope-resolution): drop dead exports surfaced by knip Knip flagged 44+ dead exports in the PR surface. Cleanup: Barrel deletion: - Remove src/core/ingestion/scope-resolution/index.ts entirely. It re-exported 30+ symbols but only one file (languages/python/scope-resolver.ts) imported from it, and only 7 symbols. Matches the project's "no barrel re-exports" preference and removes a drift surface. scope-resolver.ts now imports from concrete files (passes/mro.ts, scope/walkers.ts, contract/...). Dead functions/interfaces removed: - resolvePythonScope + ResolvePythonScopeInput + ResolvePythonScopeStats in languages/python/scope-resolver.ts — never called. pipelinePhase reaches pythonScopeResolver via SCOPE_RESOLVERS, not via a per-language entry point. - getScopeResolver in scope-resolution/pipeline/registry.ts — had zero callers. Consumers read SCOPE_RESOLVERS directly. Exports demoted to module-internal (used only within their own file): - PYTHON_SCOPE_QUERY (query.ts) + its re-export from python/index.ts - PROF (cache-stats.ts) - PythonArityMetadata (arity-metadata.ts) - ReferenceSiteSkipSet (graph-bridge/references-to-edges.ts) - ReceiverBoundProviderSubset (passes/receiver-bound-calls.ts) - ResolveCompoundReceiverOptions interface (passes/compound-receiver.ts) - matchingOpenParen function (passes/compound-receiver.ts) - followChainPostFinalize function (passes/imported-return-types.ts) - RunScopeResolutionInput + RunScopeResolutionStats (pipeline/run.ts) Also removed: - Redundant `export type { Scope }` re-export from contract/scope-resolver.ts (consumers import Scope directly from gitnexus-shared). Verification: knip reports zero dead exports in PR-touched files. 204/204 test/integration/resolvers/python.test.ts both flag paths. 335/335 scope-resolution + graph unit tests. tsc clean. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> Co-authored-by: Gergo Magyar <gergomagyar@icloud.com>	2026-04-21 15:50:00 +01:00
Flavius Miron	3c896cdbcd	fix: close remaining Dart language support gaps (#524) ... * fix: close remaining Dart language support gaps Four issues that were not addressed in PR #204: 1. extractFunctionName: add function_signature/method_signature handlers and add both to FUNCTION_NODE_TYPES. Without this, findEnclosingFunctionId cannot resolve Dart function scopes — all calls inside Dart functions have no sourceId, breaking CALLS edge attribution. 2. formal_parameter_list: add to paramListTypes in extractMethodSignature. Dart's tree-sitter grammar uses this node type (not formal_parameters), so parameter counting returns 0 for all Dart functions. 3. Write-access queries: add @assignment patterns for obj.field = value and this.field = value. Without these, no ACCESSES write edges are emitted for Dart code. 4. initialized_identifier guard in extractDartDeclaration: comma-separated declarations (String a, b, c) produce initialized_identifier nodes which are in DART_DECLARATION_NODE_TYPES but were unhandled — the type lives on the parent node. Also adds Dart column to the feature matrix in type-resolution-system.md. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(dart): field-type resolution, call attribution, import resolution, and integration tests Fixes five Dart language support gaps with integration tests and architectural alignment: **Tree-sitter queries** — Add field declaration patterns for typed and nullable class fields (`String name = ''`, `String? name`). Without these, Dart class fields were invisible to the pipeline (zero Property nodes, zero HAS_PROPERTY edges). **Import resolution** — Dart relative imports (`import 'models.dart'`) don't use a leading `./`. The standard resolver only recognises paths starting with `.` as relative; bare paths fell through to a Java-style dot-to-slash conversion that mangled `models.dart` into `models/dart`. Fix: prepend `./` before calling resolveStandard. **Call attribution** — Dart's tree-sitter grammar places `function_body` as a sibling of `function_signature`, not as a child wrapping both. The `findEnclosingFunction` parent-walk never found the function because the call lives inside `function_body` which is a sibling of the signature. Fix: add `enclosingFunctionFinder` hook to LanguageProvider interface (following the same strategy pattern as `labelOverride`), with the Dart-specific logic in `languages/dart.ts`. Both `parse-worker.ts` and `call-processor.ts` consume the hook generically — no Dart-specific code in the generic processors. **Receiver chain extraction** — Add `unconditional_assignable_selector` to `MEMBER_ACCESS_NODE_TYPES` so `inferCallForm` returns `'member'` for Dart method calls. Add Dart-specific receiver extraction blocks in `extractReceiverName`, `extractReceiverNode`, and a `selector` handler in `extractMixedChain` for Dart's flat sibling-selector model (vs the nested member-expression model used by all other languages). **Integration tests** — New `dart.test.ts` with field-type resolution and call-result-binding describe blocks. Fixtures: `dart-field-types/` (models.dart + app.dart) and `dart-call-result-binding/` (models.dart + app.dart). 9 passing tests, 1 skipped (ACCESSES edges for field reads depend on type-env parameter binding propagation — tracked for follow-up). --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: Gergo Magyar <gergomagyar@icloud.com>	2026-03-26 13:45:24 +00:00

Address code review findings from PR #392 senior compiler review: - Fix Java "Yes" → "No" in optional-param-arity matrix (Java has no defaults) - Simplify Kotlin hasDefaultValue while-as-if to direct const/if check - Update OPTIONAL_PARAM_TYPES comment to include Ruby - Replace per-declaration Set allocation with size-based Map iteration skip - Add 11 unit tests for multi-declarator type association and constructorTypeMap	2026-03-20 08:45:42 +00:00
Gergo Magyar	c3a2815186	feat(type-resolution): optional parameter arity resolution ... Add requiredParameterCount to SymbolDefinition and MethodSignature, enabling range-based arity filtering in filterCallableCandidates. Calls with omitted optional/default arguments now resolve correctly. Supported: TS, Python, Kotlin, C#, C++, PHP, Ruby (7 languages). Detection via OPTIONAL_PARAM_TYPES set + hasDefaultValue helper. 9 integration tests added across all 7 languages.	2026-03-20 08:14:58 +00:00
Gergo Magyar	8273324f3c	fix: address PR review — Rust await unwrap, stale doc claims, this-receiver footnote ... Review follow-ups from compiler front-end review (#379): - Rust extractPendingAssignment now calls unwrapAwait() on value before type checks, so `let user = get_user().await` resolves correctly - type-resolution-system.md: removed "no fixpoint inference" from limitations, updated "Single-pass" to "Walk + fixpoint", replaced stale single-pass Tier 2 description with fixpoint loop explanation - type-resolution-roadmap.md: Phase 9 body updated — 9C is delivered, 9B walk-order dependency documented (for-loop Tier 0b runs before fixpoint, so fixpoint-resolved types can't update loop variables) - Added this/self/$this fixpoint gap footnote to feature matrix	2026-03-19 12:14:54 +00:00
Gergo Magyar	e6b8edc1ac	feat: Phase 9C unified fixpoint with field access and method-call-result binding ... Replace the sequential Tier 2b/2a propagation with a unified fixpoint loop that handles four binding kinds: callResult, copy, fieldAccess, and methodCallResult. The loop iterates until no new bindings are produced (max 10 iterations), enabling arbitrary-depth mixed chains: const user = getUser(); // callResult → User const addr = user.address; // fieldAccess → Address const city = addr.getCity(); // methodCallResult → City city.save(); // resolves to City#save Infrastructure: - PendingAssignment union extended with fieldAccess and methodCallResult - resolveFieldType helper: typeName → class nodeId → lookupFieldByOwner - resolveMethodReturnType helper: typeName → class nodeId → lookupFuzzyCallable filtered by ownerId - Fixpoint also resolves reverse-order copy chains that single-pass missed Languages: TS, JS, Java, Kotlin, C#, Go, Rust, Python, PHP, Ruby, C++. Each gets field access and/or method-call-with-receiver detection in extractPendingAssignment, plus method-chain-binding test fixtures.	2026-03-19 11:50:50 +00:00
Gergo Magyar	5769872b70	feat: Phase 9 call-result variable binding across 11 languages ... Activate the dormant Tier 2b pendingCallResults infrastructure in type-env.ts by extending each language's extractPendingAssignment to emit { kind: 'callResult', lhs, callee } when the RHS of an untyped variable declaration is a simple function call. This enables `var user = getUser(); user.save()` to resolve at TypeEnv build time. Tier 2b now runs before Tier 2a copy-propagation, enabling mixed chains like `const user = getUser(); const alias = user; alias.save()`. Languages: TS, JS, Java, Kotlin, C#, Go, Rust, Python, PHP, Ruby, C++. Swift excluded. Each language gets a call-result-binding test fixture and integration tests. Conservative: only simple calls (no method calls with receivers), only when exactly one callable matches, first-writer-wins.	2026-03-19 08:59:16 +00:00
Gergő Magyar	973c7bfbf0	feat: ACCESSES edge type with read/write field access tracking (#372) ... * feat: Phase 1 ACCESSES edge type — read tracking from chain resolution Add ACCESSES relationship type to track field read access during call chain resolution. When walkMixedChain resolves a field access (e.g., user.address.save()), an ACCESSES edge with reason 'read' is emitted from the calling function to the Property node. Schema: ACCESSES added to RelationshipType, REL_TYPES, VALID_RELATION_TYPES, context queries, tools/resources descriptions. Excluded from default impact BFS to prevent traversal explosion. Implementation: resolveFieldAccessType now returns FieldResolution with fieldNodeId. walkMixedChain accepts optional onFieldResolved callback. makeAccessEmitter factory provides Set-based dedup per source node. Bug fix: Added Java 'field_access' to FIELD_ACCESS_NODE_TYPES — was missing, causing extractMixedChain to fail for Java member access. * feat: Phase 2 ACCESSES write edges — assignment detection across 12 languages Add tree-sitter query patterns for field write detection (obj.field = value) across all supported languages: TS/JS, Python, Java, Go, C++, C#, Rust, PHP, Ruby (setter syntax), Kotlin, Swift. Processing: Sequential path handles assignment captures inline. Worker path extracts ExtractedAssignment data for deferred resolution via new processAssignmentsFromExtracted function. Bug fix: Kotlin/Swift assignment queries used invalid navigation_expression wrapper — fixed to match actual directly_assignable_expression AST structure. Tests: Write access integration tests for TS, Java, Python, Go with dedicated fixtures. All use strict toBe() assertions. * test: add unit tests for call-routing, shared type extractors, and symbol-table branches Add 215 new unit tests across 3 files to increase branch coverage toward the 23% global threshold (was 21.49%): - call-routing.test.ts (49 tests): Ruby call routing — require/require_relative, include/extend/prepend heritage, attr_accessor properties with YARD types - shared-type-extractors.test.ts (108 tests): pure string functions — extractElementTypeFromString, stripNullable, extractReturnTypeName, methodToTypeArgPosition, getContainerDescriptor - symbol-table.test.ts (+29 tests): Property/fieldByOwner index, metadata spread branches, lazy callable index, lookupExactFull shape * fix: defer write-access resolution to fix Ruby cross-file property timing Ruby attr_accessor properties are registered during processCalls (not the parsing phase), so lookupFieldByOwner fails when service.rb is processed before models.rb. Fix by collecting pending write-access edges during the file loop and resolving them after all files are done. Also adds write-access integration tests and fixtures for 7 languages (C++, C#, JS, Kotlin, PHP, Ruby, Rust), Ruby compound assignment query, PHP static property write query, and Kotlin property type extraction. * fix: address PR #372 review — write-access constructor bindings parity and docs - Add verified constructor bindings fallback to write-access resolution in both sequential path (receiverIndex lookup) and worker path (constructorBindings param for processAssignmentsFromExtracted), closing the read/write ACCESSES edge asymmetry for factory-returned receivers - Clarify inner guard control flow comment in processCalls match loop - Document Go inc_statement/dec_statement gap in roadmap - Clarify PHP nullsafe write footnote (invalid syntax, not just untracked) - Update symbol-table tests for intentional fieldByOwner behavior change (Properties without declaredType now indexed for dynamic language write-access tracking)	2026-03-19 03:48:04 +05:30
Gergő Magyar	11a3d0515c	feat: Phase 8 field/property type resolution (#354) ... * feat: Phase 8 field/property type resolution — resolve chained member access Add field/property type extraction to the type resolution system so that chained member access like `user.address.save()` resolves the intermediate receiver type (`address → Address`) through Property symbols in SymbolTable. Key changes: - SymbolTable: add `declaredType` field, `fieldByOwner` O(1) index, `lookupFieldByOwner()` method, P0 conditional callableIndex invalidation, P2 exclude Properties from globalIndex to prevent namespace pollution - tree-sitter queries: add `definition.property` for TypeScript, Java, Go - parse-worker: extract declared types for Property nodes via `extractPropertyDeclaredType()`, capture field-access receiver info - call-processor: add `resolveFieldAccessType()` helper and field-access branch in both sequential and worker receiver resolution paths - Integration tests: new field-types test suite verifying end-to-end `user.address.save() → Address#save` resolution * fix: Go tree-sitter query captures field_declaration not field_declaration_list Post-review fix: the Go struct field query incorrectly put @definition.property on field_declaration_list (the list container) instead of field_declaration (the individual field). Also removed unused `language` parameter from extractPropertyDeclaredType. * feat: expand field-type tests to 6 languages, fix Go ownerId and Kotlin navigation_expression - Add integration test fixtures for Java, C#, Go, Kotlin, PHP (alongside existing TS) - Fix Go: add type_declaration handling in findEnclosingClassId for struct fields (field_declaration → field_declaration_list → struct_type → type_spec → type_declaration) - Fix Kotlin: add navigation_expression handling in field-access resolution (Kotlin uses navigation_expression + navigation_suffix, not member_expression) - Add extractMemberAccessParts helper in call-processor for cross-language member access - All 24 field-type tests pass across 6 languages, 181 Go+Kotlin tests pass with no regressions * refactor: split HAS_METHOD into HAS_METHOD + HAS_PROPERTY edge types Property nodes now use HAS_PROPERTY edges instead of HAS_METHOD, giving the graph schema proper semantic separation between methods and fields. - HAS_METHOD: Method, Constructor, Function (when inside a class) - HAS_PROPERTY: Property nodes (class fields, struct fields, attributes) MRO processor only reads HAS_METHOD — properties correctly excluded from method resolution order. Impact analysis accepts both edge types. Updated 12 files: graph types, schema, tools docs, parse-worker, parsing-processor, call-processor, and 6 test files. * fix(test): update security test to expect 7 VALID_RELATION_TYPES (added HAS_PROPERTY) * test: add unit tests for Phase 8 SymbolTable features (39 tests, up from 19) Cover all new branches: declaredType metadata, Property exclusion from globalIndex, conditional callableIndex invalidation, lookupFieldByOwner (happy path + edge cases), lookupFuzzyCallable filtering, and clear() with fieldByOwner. Fixes branch coverage threshold (21.8% → 23%+). * feat: Phase 8B mixed field+method chain resolution, C++/Rust chain fixes Unify field and method chain resolution into a single `extractMixedChain` walker that handles interleaved patterns like `svc.getUser().address.save()`. Fix C++ chain calls (tree-sitter-cpp `field_expression` uses `argument` not `object`), Rust unit struct instantiation (`let svc = TypeName;`), and add stdlib passthrough for `unwrap()`/`clone()`/`expect()` in chain loops. Key changes: - Replace `receiverCallChain` + `receiverFieldAccess` with unified `receiverMixedChain: MixedChainStep[]` on ExtractedCall - Add `extractMixedChain` in utils.ts (handles both call_expression and field_expression nodes, including C++ `argument` field) - Add `TYPE_PRESERVING_METHODS` set for stdlib identity operations - Add C++ inline method double-indexing guard in parsing-processor.ts and parse-worker.ts - Add Rust unit struct recognition in type-extractors/rust.ts - Split field-types.test.ts into per-language test files - Add ts-mixed-chain fixture and integration tests - Resolve rust.test.ts todo: Option<T>.unwrap().save() now works - Update roadmap: Phases 7+8 complete, Phase 9 is next * fix: Python declaredType extraction and sequential-path property registration - Move @definition.property capture from expression_statement to assignment node in Python queries so Strategy 1 childForFieldName('type') succeeds - Pass item.declaredType through ctx.symbols.add in sequential call-processor path, matching worker path behavior (fixes Ruby YARD declaredType drop) - Add Python chain resolution integration test (user.address.save → Address#save) - Update Rust/Python status in roadmap and system docs to reflect actual coverage * fix: Python/Ruby field type disambiguation and Rust chain test Three fixes from PR #354 third review: 1. Python typed_parameter name extraction: tree-sitter-python's typed_parameter uses positional children for the name, not a named field. TypeEnv and extractParameter now fall back to firstNamedChild. 2. Ruby/Python call-step field resolution: Ruby's AST uses `call` nodes for both property access and method calls. The chain walker now tries resolveFieldAccessType before resolveCallTarget for call steps, so attr_accessor properties resolve via declaredType. 3. Rust chain resolution test: added missing integration test asserting user.address.save() resolves to Address#save. Also splits C/C++ and TS/JS columns in type-resolution-system.md language matrix with footnotes for accuracy. 1062 resolver integration tests passing, 0 failures. * refactor: Phase 8 code review cleanup — extract walkMixedChain, fix MCP agent gaps - Extract duplicated chain resolution loop into shared walkMixedChain() helper, eliminating ~60 lines of copy-pasted code between sequential and worker paths - Add returnType to ResolveResult, removing redundant lookupFuzzy+find per chain step - Fix context() tool to include HAS_METHOD, HAS_PROPERTY, OVERRIDES in queries so agents can discover class members - Fix p.declaredType Cypher example (column doesn't exist) → p.description - Add HAS_METHOD, HAS_PROPERTY, OVERRIDES to schema resource - Document HAS_METHOD/HAS_PROPERTY in impact tool description - Delete dead code extractMemberAccessParts (superseded by extractMixedChain) - Replace any with SyntaxNode on extractPropertyDeclaredType - Add Rust deep-field-chain test (5 tests), Java mixed-chain (4), Go mixed-chain (4) - All 1075 tests pass (13 new, 0 regressions) * refactor: type SymbolDefinition.type as NodeLabel, add O(1) receiver index - Change SymbolDefinition.type from string to NodeLabel union (35 members) across symbol-table.ts, parse-worker.ts, parsing-processor.ts — compiler now enforces correctness at all comparison/assignment sites - Replace O(N*M) linear scan in lookupReceiverType with pre-built ReceiverTypeIndex (Map<funcName, Map<varName, Entry>>) for O(1) lookups with proper ambiguity handling and file-level fallback - All 1075 tests pass, 0 regressions * fix: capture C++ pointer/ref fields, Kotlin data class props, PHP constructor promotion Add tree-sitter query patterns for three previously missed property declaration forms: C++ pointer/reference member fields (Address* addr; Address& ref;), Kotlin primary constructor val/var parameters (data class User(val name: String)), and PHP 8.0+ constructor property promotion (public Address $address). Fix "10 languages" off-by-one in docs (Ruby is single-level only, not deep chain). Update Python feature matrix cell from No* to Yes* after 31b95f0 fix. 11 new integration tests with per-language fixtures verify property capture, HAS_PROPERTY edge emission, and field-access chain resolution.	2026-03-18 18:47:33 +00:00
Gergő Magyar	604b575e4b	feat: Phase 7 type resolution — return-aware loop inference & PHP class-property iterables (#341) ... * feat(type-resolution): Phase 7.1+7.2 foundation — ReturnTypeLookup, context object, pendingCallResults - Move extractReturnTypeName + helpers from call-processor.ts to type-extractors/shared.ts (breaks circular import risk: call-processor → type-env → type-extractors → call-processor) - Add SymbolTable.lookupFuzzyCallable(name) — lazy callable-only index, O(1) per call, invalidated on add(); avoids per-call .filter() on lookupFuzzy results - Add ReturnTypeLookup interface (conservative: undefined when 0 or 2+ callables match) - Add ForLoopExtractorContext interface — replaces 4 positional params with context object; update all 10 language extractor implementations (go, ts, py, jvm×2, cs, rs, rb, php, c-cpp) - Add PendingAssignment discriminated union (kind: 'copy' | 'callResult'); update PendingAssignmentExtractor in all 9 language extractors that implement it - Wire buildTypeEnv: build ReturnTypeLookup from optional symbolTable; split pendingAssignments into pendingCopies + pendingCallResults; add Tier 2b call-result propagation loop - Update call-processor.test.ts to import extractReturnTypeName from shared.ts * feat(type-resolution): Phase 7.3 — call_expression iterables in for-loop extractors (7 languages) Extends for-loop type extraction in all 7 typed-iteration languages to resolve element types when the iterable is a direct function call. **New capability**: `for (var u : getUsers())` in Java, `for u in get_users()` in Python, `for user in getUsers()` in TypeScript, etc. now resolve `u`/`user` to the callee's return element type via lookupRawReturnType + extractElementTypeFromString. Changes per language: - types.ts: extend ReturnTypeLookup with lookupRawReturnType (raw return string for container-type extraction); update ForLoopExtractorContext with returnTypeLookup field - type-env.ts: implement lookupRawReturnType on the concrete ReturnTypeLookup built in buildTypeEnv (same guards as lookupReturnType, no extractReturnTypeName) - go.ts: call_expression branch in range_clause — identifier func or selector_expression method; existing isChannelType guards updated - typescript.ts: identifier fn branch inside call_expression handler - python.ts: identifier fn branch inside call handler - jvm.ts (Java): method_invocation without object field in enhanced_for_statement - jvm.ts (Kotlin): simple_identifier callee branch in call_expression node - csharp.ts: identifier fn branch in invocation_expression handler - rust.ts: identifier func branch in call_expression handler (alongside existing field_expression/method-call path) All branches follow the same conservative pattern: lookupRawReturnType(callee) → extractElementTypeFromString → bind loop var * feat(type-resolution): Phase 7.4 — PHP \$this->property iterable via @var class property scan Adds Strategy C to PHP's extractForLoopBinding for the pattern: foreach (\$this->property as \$item) when Strategy A (resolveIterableElementType) and Strategy B (scopeEnv lookup) both fail to find the element type. Strategy C: when the iterable is a member_access_expression with object '$this', walk up the AST to the enclosing class_declaration, scan its declaration_list for a property_declaration whose variable_name matches the property, and extract the element type from: 1. PHPDoc @var annotation on a preceding comment sibling (/** @var User[] */) 2. PHP 7.4+ native type field (e.g. UserRepo \$repo — skips generic 'array') This eliminates the @param workaround that was previously required in the php-foreach-member-access fixture (which used @param User[] \$users on the method to populate the method's scopeEnv with a \$users binding). New helpers in php.ts: - PHPDOC_VAR_RE: regex for @var extraction - extractClassPropertyElementType: reads @var or native type from a property_declaration - findClassPropertyElementType: scans class body for a named property Tests added (type-env.test.ts): - PHP: resolves from @var User[] without @param workaround - PHP: conservative — no binding for unknown property - PHP: multi-class file — both classes resolve independently Fixture updated (php-foreach-member-access/App.php): - Removed the @param User[] \$users workaround from processMembers() - Test now validates the natural class-property-based resolution path * docs: mark Phase 7 complete in type-resolution-roadmap.md Records that 7A (call_expression iterables, 7 languages), 7B (PHP $this->property via @var scan), and 7C (ReturnTypeLookup + context object) are all shipped. Adds implementation notes and strikethroughs on resolved language-specific gaps. * fix(docs): update project references to feat-phase7-type-resolution in AGENTS.md and CLAUDE.md * feat(type-resolution): Phase 7.5 — PHP call_expression foreach + integration tests for 7 languages Add integration test coverage for Phase 7.3's call_expression iterable resolution across all 7 languages (Go, TypeScript, Python, Java, Kotlin, PHP, Rust). Each test creates a fixture with competing User/Repo classes that both define save(), then verifies for-loop iteration over a function call's return value resolves to the correct class. PHP was missing function_call_expression support in its for-loop extractor. Three changes fix this: - php.ts extractForLoopBinding: handle function_call_expression and member_call_expression iterables via returnTypeLookup - php.ts normalizePhpReturnType: preserve array notation (User[]) in SymbolTable so lookupRawReturnType returns useful container types - parse-worker.ts + parsing-processor.ts: upgrade uninformative AST return types (array, iterable) with PHPDoc @return annotations 35 new integration tests (5 per language), 2525 total tests passing. * fix(type-resolution): address PR #341 review findings — PHP asymmetry + dormant infrastructure docs - Replace normalizePhpType with extractElementTypeFromString in PHP call-expression foreach paths, aligning with all 6 other language extractors and preventing incorrect binding of bare non-container types like User - Add NOTE comments clarifying pendingCallResults Tier 2b is infrastructure-ready but no extractor populates it yet - Expand Go channel-type comments explaining why non-channel assumption is safe * fix(type-resolution): address verification review — docs accuracy + PHP fallback guard - Roadmap lines 86/100: correct pendingCallResults from "active" to "dormant infrastructure (Phase 9)" - type-resolution-system.md line 363: update to reflect Phase 7.3 loop inference is delivered - type-resolution-system.md line 409: clarify for-loop call-expression resolution (done) vs general assignment propagation (pending) - php.ts:127: add declaration_list type guard on fallback to prevent silent wrong results	2026-03-18 08:39:38 +00:00
Gergő Magyar	f0132c1077	feat: Phase 6 type resolution — for-loop Tier 1c, pattern matching, container descriptors, 10-language coverage (#318) ... * feat: Phase 6 type resolution — pattern matching, for-loop Tier 1c, coverage completion - Add patternBindingNodeTypes gate to LanguageTypeConfig for 50% perf improvement - Expand ForLoopExtractor signature with optional declarationTypeNodes + scope - Add extractElementTypeFromString shared utility for container type parsing - Python match/case: extractPatternBinding for `case User() as u:` pattern - C# refactor: move is_pattern_expression from extractDeclaration to extractPatternBinding - Ruby: add extractPendingAssignment for assignment chain propagation - TS/JS: add for-loop Tier 1c for `for (const user of users)` with User[] inference - Python: add for-loop Tier 1c for `for user in users:` with type annotation inference - Go: add for-loop Tier 1c for `for _, user := range users` with []User inference - Fix 'Property' as any stale cast in call-processor.ts - Add dual return-type string length cap (2048 pre-cap, 512 post-cap) - Add chain call integration tests for C#, Go, Rust, Python, JS, C++ - Add Python match/case integration test fixtures - 27 new extractElementTypeFromString unit tests - 3 for-loop edge cases skipped (declarationTypeNodes scope key lookup) * fix: address code review findings for Phase 6 - Add missing patternBindingNodeTypes to C# typeConfig (perf gate) - Add 2048-char input length guard to extractElementTypeFromString - Skip Python match/case integration tests (call extraction needs query updates) * reorganise * fix: Phase 1 bug fixes — Go range semantics, typed_parameter, bracket depth - Go single-var range correctly returns early for slices/maps (index, not element) - Go single-var range on channels correctly resolves element type - Added map_type and channel_type to extractGoElementTypeFromTypeNode - Added isChannelType helper for channel detection before skip decision - Added 'typed_parameter' to TYPED_PARAMETER_TYPES for Python annotated params - Fixed bracket depth tracking in extractElementTypeFromString — only match selected closeChar at depth 0, return undefined for mismatched brackets - Un-skipped 3 prematurely skipped tests (TS local const, Python List/Sequence) - Added tests for map range, single-var range semantics, bracket edge cases * refactor: Phase 2 architecture — shared helper, required params, decoupled type nodes - Extract resolveIterableElementType shared helper in shared.ts implementing 3-strategy fallback (declarationTypeNodes → scopeEnv string → AST walk) - Refactor TS, Python, Go extractors to use shared helper (eliminates 3x duplication) - Make ForLoopExtractor params required (aligned with PatternBindingExtractor) - Update Java, Kotlin, C# extractor signatures to accept required params - Decouple declarationTypeNodes from scopeEnv — capture raw type annotation nodes BEFORE extractDeclaration for container types (User[], []User, List[User]) - Hybrid approach: direct name extraction + keysBefore fallback for multi-declarator - Document declarationTypeNodes invariant change (superset of scopeEnv) * feat: Phase 3 partial — Rust for-loop + C# var foreach Tier 1c - Rust: add extractForLoopBinding with for_expression support - Handles &users, &mut users via reference_expression unwrapping - extractRustElementTypeFromTypeNode: generic_type, reference_type, slice/array - findRustParamElementType: AST walk with reference/mut pattern unwrapping - 4 unit tests (Vec<User>, &[User], range expr negative, no-annotation negative) - C#: upgrade foreach to handle var (implicit_type) via Tier 1c - extractCSharpElementTypeFromTypeNode: generic_name, array_type, nullable_type - findCSharpParamElementType: AST walk to method_declaration parameters - 3 unit tests (var foreach, explicit type regression, no-annotation negative) * feat: Phase 3 complete — all language gaps + pattern matching Kotlin Tier 1c: - Unannotated for-loop resolves via shared helper - extractKotlinElementTypeFromTypeNode handles type_projection unwrapping - findKotlinParamElementType walks to function_declaration Java Tier 1c: - var foreach resolves via shared helper - extractJavaElementTypeFromTypeNode handles generic_type, array_type - findJavaParamElementType walks to method_declaration TypeScript: - readonly User[] unwrapped via readonly_type → array_type recursion C# switch patterns: - declaration_pattern added to patternBindingNodeTypes - extractPatternBinding handles standalone declaration_pattern (switch case/expr) Rust match arms: - match_arm added to patternBindingNodeTypes - extractPatternBinding extended with match_arm → match_expression parent traversal Python: - as_pattern tries childForFieldName('alias') before positional fallback Tests: 237 pass (was 224), 13 new tests added * feat: Phase 4 — known limitation tests, match arm fix, final verification - Fix Rust match_arm pattern extraction: unwrap match_pattern to get tuple_struct_pattern inside (tree-sitter-rust wraps in match_pattern node) - Add first-writer-wins regression test for match arm scope leakage - Add 5 documented skip tests for known limitations: - TS destructured for-of (tuple destructuring) - Python tuple unpacking in for-loops - TS instanceof narrowing (block-level scoping) - Rust for with .iter() (method call iterable) - Ruby block parameters (closure param inference) Final: 238 passed, 5 skipped (documented limitations), tsc clean * test: integration tests for all Phase 6 language gaps + fix Rust param pattern field Integration test fixtures and tests (30 new tests, all with exact match + negative): Rust for-loop (5 tests): - for user in &users with Vec<User> → User#save, negative Repo#save - for repo in &repos with Vec<Repo> → Repo#save, negative User#save Rust match arm (5 tests): - match opt { Some(user) => user.save() } → User#save, negative Repo#save -

for (const user of users) with readonly User[] → user.save, negative Bug fix: type-env.ts parameter branch now falls back to childForFieldName('pattern') for Rust parameters (Rust uses 'pattern' not 'name' for parameter names) * test: add assertion bodies to known limitation skip tests Convert empty skip test stubs to proper tests with parse/buildTypeEnv/expect assertions following the codebase convention (e.g., call-processor.test.ts:319). Each skip test now documents the exact expected behavior, so removing .skip will cause a meaningful failure when the limitation is eventually fixed. Also clarify Python integration skip tests as call-extraction issues (not type-env) and Swift integration skips as build-dep issues (self/super resolution code already exists in type-env.ts). * feat: resolve 4 known limitation skip tests + method-aware type arg selection Unskip 4 of 5 type-env known limitations with full integration test coverage: 1. TS destructured for-of: handle array_pattern by binding last named child to element type. Fix Map<K,V> to return last generic arg (value type). 2. Python dict.items() loop: handle `call` iterables + `pattern_list` left side. Fix dict[K,V] extraction via type_parameter with last-arg heuristic. Unwrap `type` wrapper in extractPyElementTypeFromAnnotation. 3. TS instanceof narrowing: add extractPatternBinding for binary_expression with positional child access. First-writer-wins (not block-scoped). 4. Rust .iter() for-loops: handle call_expression in for_expression value node by extracting receiver from field_expression. Method-aware type arg resolution: - Add TypeArgPosition ('first'|'last') to resolveIterableElementType - .keys()/.keySet()/.Keys → first type arg (key); all else → last (value) - Thread position through all 3 strategy callbacks in TS/Rust/Python - Add predefined_type to extractSimpleTypeName for TS primitives (string etc) New fixtures: rust-iter-for-loop, typescript-destructured-for-of, typescript-instanceof-narrowing, python-dict-items-loop. 248 unit tests pass (6 new), 1 skip (Ruby block params). * feat: container descriptor table for generic type arg resolution Replace simple KEY_METHODS heuristic with CONTAINER_DESCRIPTORS table that maps 30+ container types across all languages to their type parameter semantics per access method. Key improvements: - Container-aware resolution: HashMap.iter() correctly yields V (arity 2), while Vec.iter() yields T (arity 1) — same method, different semantics - Cross-language coverage: Map/HashMap/BTreeMap/dict/Dict/Dictionary/ ConcurrentHashMap + List/Vec/Set/HashSet/Queue/Deque/Stack etc. - Method categorization: keyMethods (keys/keySet/Keys) vs valueMethods (values/get/pop/iter/first/last) per container type - Fallback for unknown containers: still uses method name heuristic, so MyCache<K,V>.keys() correctly returns first arg - Exported getContainerDescriptor() for future heritage-chain lookups Each language extractor now passes containerTypeName from scopeEnv to methodToTypeArgPosition for descriptor-aware resolution. 252 unit tests pass (4 new descriptor tests), 1 skip (Ruby). * feat: method-aware for-loop extractors + integration tests for all languages Upgrade 4 existing extractors + create 3 new ones for full cross-language coverage of call_expression iterables and container descriptor resolution: Upgraded (add call expr iterable + methodToTypeArgPosition): - Java: method_invocation (data.keySet(), data.values()) - Kotlin: navigation_expression + call_expression (data.keys, data.values()) - C#: member_access_expression + invocation_expression (data.Keys, data.Values) - Go: TypeArgPosition threading for Go 1.18+ generics New for-loop extractors: - C++: for_range_loop with auto& unwrapping, template_type + qualified_identifier (std::vector<User>) extraction, explicit vs auto type handling - PHP: foreach_statement with simple/key-value/by-reference forms, PHPDoc @param priority over AST array type - Ruby: for-in with YARD @param type resolution via comment parsing Integration test fixtures + tests for all 6 languages: - java-map-keys-values (Map.values() + List iteration) - kotlin-map-keys-values (HashMap.values + List iteration) - csharp-dictionary-keys-values (Dictionary.Values foreach) - cpp-range-for (auto& + const auto& range-based for) - php-foreach-loop (foreach with PHPDoc @param User[]) - ruby-for-in-loop (for-in with YARD @param Array<User>) Bugs fixed during integration testing: - C++: qualified_identifier (std::vector) not unwrapped to template_type - PHP: extractParameter overwrote PHPDoc-derived types with bare 'array' 252 unit tests pass, 201 integration tests pass across 6 languages. * fix: update extractElementTypeFromString tests for last-arg default TypeArgPosition change (default 'last') broke 5 existing tests expecting first arg from multi-arg generics. Updated expectations and added explicit pos='first' tests for key type extraction. * fix: rename C++ fixture files to correct case for case-sensitive CI On case-sensitive filesystems (Linux/macOS CI), git tracked both the old lowercase files (app.cpp, user.h) and the new uppercase files (App.cpp, User.h) as separate files. The pipeline processed both, causing the old app.cpp (with explicit User& type) to interfere with the new auto& test. Removes old lowercase entries and re-adds with uppercase casing to match the #include directives in the fixture. * feat: PR #318 review findings — pattern bindings, member access iterables, structured bindings Address all 7 genuine gaps identified in PR #318 deep code review: - Kotlin: add extractKotlinPatternBinding for when/is (type_test AST node) with allowPatternBindingOverwrite for smart-cast semantics - Java: add type_pattern branch for Java 17+ switch pattern variables - TypeScript: explicit object_pattern skip in for-of (no false bindings) - Cross-language: member access iterables (self.users, this.users, repo.users) across all 10 language extractors - C++: structured_binding_declarator handling in range-for (last-child heuristic) - Rust: closure_parameter added to TYPED_PARAMETER_TYPES - PHP: normalizePhpType handles angle-bracket generics (Collection<User>) Code review fixes applied: - Remove 4 debug console.log statements (c-cpp.ts, call-processor.ts) - Hoist KNOWN_CONTAINER_PROPS to module scope (csharp.ts) - Guard keysBefore allocation behind typeNode check (type-env.ts) - Add depth limits (50) to 7 recursive type extraction functions - Add 2048-char length cap to extractSimpleTypeName - Fix PHP/Ruby missing typeArgPos parameter in resolveIterableElementType Integration test fixtures: kotlin-when-pattern, java-switch-pattern, cpp-structured-binding, typescript-member-access-for-loop, python-member-access-for-loop * fix: position-indexed when/is bindings, Kotlin param extraction, HashMap.values for-loop Three root causes for failing Kotlin integration tests: 1. When/is multi-arm resolution: flat scopeEnv stored only the last arm's type (last-writer-wins). Added PatternOverrides with AST range indexing so each when arm resolves to its narrowed type independently. 2. HashMap.values for-loop: navigation_expression without call_suffix was classified as bare property access (iterableName='values' instead of 'data'). Now tries object-as-iterable + property-as-method first, with fallback to property-as-iterable for this.users patterns. 3. Kotlin parameter extraction: tree-sitter-kotlin parameter nodes use positional children (simple_identifier, user_type) not named fields (name, type). Added fallback to findChildByType in both extractKotlinParameter and extractTypeBinding. Integration tests added for .keys/.values/Set/MutableMap iteration, 3-arm when/is, multi-call within arms, and when+else branch. * feat: enhance PHP type resolution for generics and member access in foreach loops * feat: Phase 6.1 type resolution gap closure — container descriptors, recursive_pattern, class fields Add 13 missing container type descriptors (Collection, MutableMap, Stream, SortedSet, etc.) to CONTAINER_DESCRIPTORS for correct element type extraction across C#, Kotlin, and Java. Extend C# pattern binding to handle recursive_pattern (obj is User { Name: "Alice" } u) in both is-expression and switch expression contexts. Add TypeScript class field declaration support (public_field_definition) so for-loop iteration over this.fieldName resolves element types from class field type annotations. Includes file-scope fallback in resolveIterableElementType and nested member_expression handling for this.field.method() patterns. * docs: add type resolution system documentation with roadmap Covers the full architecture, resolution tiers (0-2), scope model, language feature matrix, container descriptors, pipeline integration, and the Phase 7-9 roadmap for cross-scope propagation, field-type resolution, and return-type-aware binding. * feat: Phase 6.2 review findings — C# nested member foreach, C++ deref range-for, Java field_access Close two gaps found during fourth-pass review of PR #318: - C# foreach (var user in this.data.Values): nested member_access_expression now extracts intermediate property name for scopeEnv lookup - C++ for (auto& user : *ptr): pointer_expression dereference now recognized as range-for iterable Root causes fixed in shared infrastructure: - extractSimpleTypeName: add template_type (C++) and generic_name (C#) - extractGenericTypeArgs: add generic_name for consistency - type-env.ts: unwrap variable_declaration wrapper in field_declaration for declarationTypeNodes capture (zero-allocation manual loop) Additional review findings addressed: - Java: add field_access handler for this.data.values() in method_invocation - C++ pointer_expression: document limitation (*identifier only) - TypeScript: fix stale comment about property_identifier All 525 tests pass (278 unit + 247 integration). * perf: optimize type resolution pipeline — worker threshold, skip graph phases, AST pruning - Skip worker pool creation for small repos (<15 files or <512KB) — saves 100-400ms - Add skipGraphPhases option to runPipelineFromRepo to skip MRO/community/process phases - Add conservative SKIP_SUBTREE_TYPES for leaf-only AST nodes (string, comment, number) - Pre-compute interestingNodeTypes set — single Set.has() replaces 3 checks per node - Add fastStripNullable — skip full stripNullable for simple identifiers (90%+ case) - Replace .children?.find() with manual for loops in extractFunctionName (no array alloc) - Add hookTimeout: 120000 to vitest.config.ts for CI beforeAll hooks * fix: review findings — remove template_string from SKIP_SUBTREE_TYPES, handle bare nullable keywords - Remove template_string and concatenated_string from SKIP_SUBTREE_TYPES (template literals contain interpolated expressions with typed code) - Add FAST_NULLABLE_KEYWORDS check to fastStripNullable for behavioral parity with stripNullable on bare null/undefined/void/None/nil - Add explanatory comment on extractPendingAssignment scopeEnv guard * feat: add type resolution system and roadmap documentation	2026-03-17 17:10:22 +00:00
