feat(ingestion): Link object literal methods to exported bindings (#1718)
* fix: link object literal methods to exported bindings

* fix(ingestion): bridge object-literal value receivers in scope-resolution (PR #1718 review)

Addresses adversarial production-readiness review on PR #1718 / issue #1358:
- F1 (caller resolution) — setting `ownerId` on object-literal method symbols
  alone is not sufficient; the scope-resolution receiver-bound resolver only
  consults class-like or type-annotated bindings, so lowercase value receivers
  (`export const fooService = {...}; fooService.getUser(...)`) never reach the
  owner-indexed lookup. Adds a Case 5 value-receiver bridge in
  receiver-bound-calls.ts that resolves the receiver name as a Const/Variable
  binding, translates its def to the canonical graph node id, and emits the
  CALLS edge via the owner-indexed method registry.
- F2 (boundary guard) — rewrites findObjectLiteralBindingInfo as an explicit
  two-phase AST walk: Phase A tracks object-literal depth (returns null for
  nested literals and pre-declarator function/class boundaries — IIFE
  patterns); Phase B walks the declarator's ancestors and rejects function,
  class, and block-statement containers (if / for / while / try / catch /
  switch / etc.) before reaching program/export_statement. Prevents false
  HAS_METHOD edges for locally-scoped or block-scoped object literals.
- F4 — drops the dead `ownerName` field from ObjectLiteralBindingInfo.

Constraint: TS/JS are scope-resolution migrated per RFC #909; the legacy
Call-Resolution DAG (call-processor.ts) is intentionally left untouched.

Tests:
- test/integration/ast-helpers-object-literal-binding.test.ts (13 cases) —
  pins helper semantics: happy paths, function/arrow/class-ctor boundaries,
  nested literals, block scope (if / for-of / try), IIFE, assignment
  expressions without declarator.
- test/integration/object-literal-owner-resolution.test.ts (9 cases) —
  drives the full pipeline against an on-disk fixture: sequential CALLS edge
  emission (issue #1358 proof), worker-mode parity, negative local binding,
  and nested-literal attribution boundary.

Full sweep: 2958/2958 integration + 6056/6056 unit tests pass.

* refactor(ingestion): address code-review findings on object-literal owner resolution

Multi-agent code review on the prior commit surfaced 7 actionable findings,
all walked through and applied here. None change observable behavior for
issue #1358's fix; all harden correctness, predicate stability, and test
signal.

- #1 (P1 / 3-reviewer corroboration): Case 5 in receiver-bound-calls.ts no
  longer hand-builds graph.addRelationship + a dedup key. New
  tryEmitEdgeWithExplicitTargetId in edges.ts takes a pre-resolved target
  id (the canonical Method nodeId from the parser) and reuses every
  invariant of tryEmitEdge: dedup-key format, collapse-flag honoring,
  caller-id resolution, rel-id shape, mapReferenceKindToEdgeType for
  read/write ACCESSES. This also lands the adversarial reviewer's "F2"
  follow-up (hardcoded type: 'CALLS' for non-call sites) for free.

- #2 (P2 cross-reviewer): findValueBindingInScope's predicate inverted
  from denylist ("not class-like and not callable") to explicit allowlist
  matching reconcileOwnership's registration set:
  Const | Variable | Property | Static. Extracted as isOwnableValueLabel
  so future NodeLabel additions require an explicit opt-in.

- #6 (P2): walkScopeChain<T>() extracted; both findClassBindingInScope
  and findValueBindingInScope now route through it. Local scope.bindings
  are exhausted BEFORE lookupBindingsAt (imported/augmented) at every
  scope level — preserves JavaScript lexical scoping where a local const
  shadows an imported binding of the same name. Behavior was already
  correct in findClassBindingInScope but was implicit; now it is the
  walker's explicit, documented contract.

- #7 (P2): scope-walker duplication closed. findClassBindingInScope and
  findValueBindingInScope reduce to thin wrappers over walkScopeChain
  with their respective predicate. findClassBindingInScope keeps its
  qualifiedNames + dotted-name fallback tail.

- #3 (P2): parse-worker.ts hoists `const ownerId = enclosingClassId ??
  objectLiteralOwnerInfo?.ownerId` once before the symbol push, dropping
  the duplicated coalesce + `as string` cast. Matches the cast-free
  pattern at parsing-processor.ts:793. HAS_METHOD emit site reuses the
  same hoisted local.

- #4 (P2): object-literal-owner-resolution.test.ts Test A's CALLS-edge
  assertion no longer matches by name alone. .toEqual now pins the
  canonical target id (Method:src/service.ts:getUser#1 via generateId),
  confidence (0.85), and reason ('import-resolved'). A regression that
  emits the edge at confidence=0, with the wrong reason, or against a
  phantom Method node now fails the test.

- #5 (P2): worker-parity test adds a CI tripwire — when CI=1 and
  dist/parse-worker.js is missing, throw at module top with a clear
  message. Locally, skipIf(!hasDistWorker) keeps the fast-iteration
  experience; CI cannot pass with U3 (worker-path ownerId) unverified.

Verification: tsc --noEmit clean. Targeted regression sweep on
ast-helpers-object-literal-binding (13), object-literal-owner-resolution
(9), has-method (60), cross-file-binding (40) — 122/122 pass. Full unit
sweep: 6056/6056. Integration suite: 1 pre-existing Windows-flake in
worker-pool.test.ts (passes 28/28 in isolation) unrelated to this diff.

* refactor(scope-resolution): align Const label emission with legacy DAG (PR #1718 review F1)

Eliminates the architectural fragility surfaced by PR #1718's adversarial review
Finding 1. Previously, normalizeNodeLabel('const') returned 'Variable' while
the legacy DAG parse phase emits 'Const' graph nodes (via @definition.const
capture for lexical_declaration). PR #1718's Case 5 value-receiver bridge
resolved correctly only because resolveDefGraphId happened to fall back to
simpleKey after the qualified-key miss — accidental correctness.

After this change, scope-resolution defs for `const x = ...` declarations
report def.type === 'Const', matching the graph node label. resolveDefGraphId's
qualified-key path now hits on the first try; the simple-key fallback is no
longer load-bearing for value receivers and can be tightened in future without
silently breaking Case 5.

Audit completeness verification:
- Grep `\bVariable\b` across src/core/ingestion/scope-resolution/ surfaced two
  consumer sites that already accept both labels: reconcile-ownership.ts:101+168
  (`def.type === 'Variable' || def.type === 'Const' || ...`) and
  walkers.ts:207 isOwnableValueLabel (`Const | Variable | Property | Static`).
  No language hook in src/core/ingestion/languages/ branches on
  `def.type === 'Variable'` for what's actually a const declaration.
- Sentinel stress test (the full unit + integration suite run with the
  renamed label in place): 6137/6137 unit tests pass; 2967/2967 integration
  tests pass. One pre-existing Windows-only flake on worker-pool.test.ts when
  run alongside the full integration suite (passes 28/28 in isolation,
  unrelated to scope-extractor — same flake observed before this diff).

The variable mapping (`'variable' → 'Variable'`) is preserved for `var`
declarations, matching the legacy DAG's `@definition.variable` capture for
variable_declaration. The split now mirrors the parse-phase capture
distinction exactly.

Per plan docs/plans/2026-05-21-002-feat-pr1718-followups-class-instance-and-label-normalization-plan.md
U4 + U5. T1 (class-instance singleton resolution from issue #1358's second
sub-case) is deferred to a standalone pre-plan investigation, not shipped
here.

* test(ingestion): add regression coverage for issue #1358 singleton sub-cases

Closes the remaining sub-cases of issue #1358 surfaced by PR #1718's
adversarial review (Finding 4, NOTED): the class-instance singleton
(`export const fooService = new FooService();`) and the factory-pattern
singleton (`export const fooService = makeFooService();`).

Pre-plan investigation (per docs/plans/2026-05-21-002 § "Pre-Plan
Investigation Task (T1)") confirmed Outcome A for both patterns — they
already resolve end-to-end through scope-resolution's
`@type-binding.constructor` capture (languages/typescript/query.ts:489-511)
+ `propagateImportedReturnTypes` chain-follow
(scope-resolution/passes/imported-return-types.ts:114) + receiver-bound
Case 4 simple typeBinding lookup (receiver-bound-calls.ts:625). The
mechanism was wired correctly before this session; the regression-net
wasn't.

This test pins the behavior:
- Pattern 1: `caller → FooService.getUser` CALLS edge with
  confidence 0.85 and reason 'import-resolved'
- Pattern 2: same edge shape via factory chain-follow (the
  `@type-binding.alias` capture for `const u = find()` style)

Both assertions use exact `.toEqual([{...}])` shape pinning so a future
regression that targets a phantom Method node, emits at lower confidence,
or drops the cross-file import-resolved reason fails loudly.

Verification: 5/5 pass, 127/127 in targeted regression sweep including
object-literal-owner-resolution.test.ts, ast-helpers-object-literal-
binding.test.ts, has-method.test.ts, and cross-file-binding.test.ts.

No production code change. The class methods get a class-qualified node id
(`Method:src/service.ts:FooService.getUser#1`) distinguishing them from
same-name methods on other classes — distinct from the bare-name node id
shape PR #1718's object-literal case uses.

* test(resolvers): add class-instance + factory-pattern singleton coverage for TS/JS (issue #1358)

Closes the remaining sub-cases of issue #1358 surfaced by PR #1718's
adversarial review (Finding 4). PR #1718 fixed object-literal-shorthand
singletons (`export const fooService = { getUser() {} }`); this commit adds
parallel coverage for the two other singleton shapes that resolve through
the existing scope-resolution chain:

  // Pattern 1 — class-instance singleton
  export class FooService { getUser(id) { ... } }
  export const fooService = new FooService();

  // Pattern 2 — factory-pattern singleton
  export class FooService { getUser(id) { ... } }
  export function makeFooService() { return new FooService(); }
  export const fooService = makeFooService();

Pre-plan investigation (per local plan docs/plans/2026-05-21-002 § "Pre-Plan
Investigation Task (T1)") confirmed Outcome A — both patterns already
resolve end-to-end through:
  - `@type-binding.constructor` capture (languages/{typescript,javascript}/
    query.ts) seeds `fooService → FooService` at parse time
  - `propagateImportedReturnTypes` (scope-resolution/passes/
    imported-return-types.ts:114) mirrors the typeBinding cross-file
  - Receiver-bound Case 4 simple typeBinding lookup
    (scope-resolution/passes/receiver-bound-calls.ts:625) MRO-walks
    FooService and emits the CALLS edge to getUser

Tests added per language × pattern (5 each, 10 total):
- node existence (Class, Method, Function, Const, plus Function for the
  factory pattern's `makeFooService`)
- HAS_METHOD edge from class to method (class-instance variant)
- CALLS edge from caller to `getUser` with `targetFilePath: 'src/service.{ts,js}'`,
  `reason: 'import-resolved'`, `confidence: 0.85` — exact `.toEqual([{...}])`
  shape pinning so a regression that emits at lower confidence or drops the
  cross-file reason fails loudly

Fixtures placed under the existing `test/fixtures/lang-resolution/` convention.
Tests appended to `test/integration/resolvers/{typescript,javascript}.test.ts`,
matching the in-file pattern of every other resolver scenario.

Also supersedes and removes the standalone
`test/integration/class-instance-and-factory-singleton-resolution.test.ts`
introduced earlier in this PR session (`0df91b77`) — the proper home for
language-resolver scenarios is the per-language resolver test file alongside
similar fixtures (`javascript-self-this-resolution`, `javascript-cross-file`,
`typescript-tsconfig-paths`, etc.). One canonical location for the scenario,
not two.

Verification: 10/10 new singleton tests pass; 297/297 full TS+JS resolver
suite pass (no regression in any existing resolver test).

* test(resolvers): gate TS/JS singleton tests behind scope-resolution parity (CI run 26223603426)

The class-instance and factory-pattern singleton CALLS-edge resolution
tests added in c8e573bc rely on scope-resolution-only mechanisms
(`@type-binding.constructor` capture + `propagateImportedReturnTypes`
mirror + receiver-bound Case 4). The `scope-parity / typescript parity`
and `scope-parity / javascript parity` CI jobs run with
`REGISTRY_PRIMARY_TYPESCRIPT=0` / `REGISTRY_PRIMARY_JAVASCRIPT=0` and
exercise the legacy DAG path, which has no cross-file constructor-derived
typeBinding propagation. Verified by job 77202610819 (TS parity) and
77202610869 (JS parity) failing with:

  × resolves caller.fooService.getUser() to FooService.getUser via constructor-inferred typeBinding
  × resolves caller.fooService.getUser() through the factory chain to FooService.getUser

Note: my local Windows shell-prefix env-var invocation did not propagate
the flag into vitest workers correctly (the cpp parity gate's 47-skipped
behavior masked the issue when I ran an ad-hoc comparison), so the
empirical "both modes pass" finding I posted earlier was wrong. CI is the
source of truth.

Changes:
- test/integration/resolvers/helpers.ts: add `typescript` and `javascript`
  entries to `LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES` for the 2 CALLS-edge
  resolution tests in each language. Node-existence and HAS_METHOD
  assertions are NOT excluded — those pass under legacy DAG (parser-level
  emission is intact).
- test/integration/resolvers/typescript.test.ts: drop the `it` import from
  vitest; replace with `const it = createResolverParityIt('typescript');`
  shadow (matches the c/cpp/csharp/go pattern at the top of those files).
- test/integration/resolvers/javascript.test.ts: same shadow with
  `createResolverParityIt('javascript')`.

Verification:
- Default mode (registry-primary): 297/297 TS+JS resolver tests pass.
- Legacy DAG mode: the 4 listed singleton CALLS-edge tests will skip; all
  other singleton assertions (node existence + HAS_METHOD edge) continue
  to run and pass under both modes.

fix(analyze): prevent cache-hit native workers from aborting (#1751)
* fix(analyze): prevent cache-hit native workers from aborting

Delay parse worker startup until a cache miss requires it, fall back to sequential parsing when initial worker readiness fails, and preserve analyzer diagnostics/progress when heap respawn captures child output.

Constraint: Node 25 and tree-sitter/N-API worker initialization can abort before ready, while warm-cache analysis should not start workers at all.

Rejected: Treating status-134/SIGABRT as heap OOM unconditionally | native worker aborts require distinct recovery guidance and stderr/stdout evidence.

Rejected: cli-progress noTTYOutput for respawn progress | it appends newline frames instead of preserving one-line redraw UX.

Confidence: high

Scope-risk: moderate

Directive: Keep parse-worker creation behind confirmed cache misses and preserve TTY-style progress when respawn pipes stderr for crash classification.

Tested: GitNexus impact analysis for ensureHeap, runChunkedParseAndResolve, createWorkerPool, WorkerPool, walkRepositoryPaths; GitNexus detect_changes scoped to staged worktree; targeted vitest for analyze respawn, parse lazy cache, filesystem walker, worker pool; npx tsc --noEmit; npm run build; NODE_OPTIONS='--max-old-space-size=8192' npm test.

Not-tested: Windows terminal rendering and published npm package install path.

* ci(docker): tolerate slower arm64 TypeScript builds

Docker PR builds run gitnexus prepare under QEMU for linux/arm64, where the fixed 120s TypeScript timeout can kill otherwise healthy builds. Increase the default timeout and allow GITNEXUS_BUILD_TIMEOUT_MS to tune slower environments without changing the build steps.

Constraint: PR #1751 Docker Build & Push gitnexus failed with spawnSync /bin/sh ETIMEDOUT while running node_modules/.bin/tsc in scripts/build.js.\nRejected: Rerunning CI only | the failure was the build script's deterministic timeout boundary under arm64 emulation, not a code assertion.\nConfidence: high\nScope-risk: narrow\nDirective: Keep build timeout changes in scripts/build.js configurable; do not hide real compiler failures, only allow slower successful compiles to finish.\nTested: GitNexus impact for gitnexus/scripts/build.js reported LOW; gitnexus detect_changes reported 1 changed file, 0 affected processes, low risk; git diff --check; gitnexus npm run build.\nNot-tested: GitHub Docker arm64 build rerun before pushing; local Docker multi-platform build under QEMU.

* fix(analyze): truncate respawn progress safely

Preserve complete ANSI escape sequences and grapheme boundaries when the respawn progress terminal shim truncates wrapped output, so the shim does not emit dangling escape bytes or split surrogate pairs while keeping raw writes untouched.

Constraint: Claude review on PR #1751 flagged `s.slice(0, width)` in createAnsiPipeTerminal.write() as a latent terminal-corruption risk.
Rejected: Adding a display-width dependency | a local helper is sufficient for this narrow respawn terminal shim and avoids new dependency churn.
Rejected: Changing silent status-134 classification | current tests already document the output-less 134 fallback as heap guidance.
Confidence: high
Scope-risk: narrow
Directive: Keep respawn terminal writes ANSI-aware and preserve rawWrite bypass semantics for callers that intentionally write control sequences.
Tested: GitNexus impact for createAnsiPipeTerminal reported LOW; GitNexus detect_changes reported 2 changed files, 3 affected processes, medium risk; targeted vitest for analyze respawn progress and heap respawn; gitnexus npx tsc --noEmit; prettier check for changed files; eslint for changed files.
Not-tested: Full npm test suite; manual terminal rendering on Windows.

fix(server): restore gitnexus serve startup under Express 5 (#1749)
* fix(server): restore gitnexus serve startup under Express 5

Express 5 rejects app.options('*'), which broke CI e2e when the backend
failed to start. Move PNA middleware before cors so preflight responses
include Access-Control-Allow-Private-Network, and add regression tests.

* test(server): address PR review — prettier, ephemeral port, cleanup

- Format integration and rate-limit test files for CI quality/format
- Use OS-assigned port instead of random 47xxx range
- Remove per-test GITNEXUS_HOME temp dir in afterEach
- Use regex for PNA-before-cors structural guard (indent-agnostic)

* fix(workers): exclude in-flight file on worker error/exit, not just singleton timeout

WorkerPoolDispatchError previously surfaced the stalled path only for the
singleton-timeout final-fail branch. Worker `error` and `exit` events (and
the msg-channel `error` reply) fell back to plain `Error`, so the sequential
fallback re-attempted every file in the active job — re-hanging on the same
pathological file when the worker crashed mid-parse.

Lift the in-flight-file inference into `inFlightExcludePath(job, lastProgress)`
and wire it into the three remaining in-pool failure sites. `lastProgress` is
already in `runWorker` scope, so `items[lastProgress]` (the next file the
worker was about to acknowledge) is the best single guess at the culprit;
earlier files are still re-tried sequentially. Returns `[]` when no path is
determinable (`lastProgress >= items.length`, or path missing/non-string) so
sequential retries the whole job.

Replacement-worker startup failures stay plain `Error` (no job context); the
result-before-flush protocol bug stays plain `Error` (code fault, not file).

Tests cover the three new exclusion paths plus a negative test confirming
non-WorkerPoolDispatchError throws fall through to full sequential retry.

* fix(review): apply autofix feedback

- Use cause-neutral "worker-excluded" label in skip messages and tests now
  that worker error/exit paths share the same exclusion contract as
  singleton-timeout (correctness + maintainability reviewers).
- Add JSDoc to findSelfOrAncestorOfType{s} explaining the parent-walk
  short-circuit vs root-DFS fallback (maintainability reviewer).

* feat(workers): resilient + scalable worker pool

Restructures `createWorkerPool` so a single bad file no longer kills the
pool for the rest of an analyze run. Five interlocking layers:

1. **Auto-respawn on error/exit** — worker death triggers `replaceWorker`
   on the same slot, bounded by `maxRespawnsPerSlot` (default 3). The slot
   is dropped from rotation when the budget is exhausted; other slots
   keep running.

2. **Circuit breaker** — replaces the permanent `poolBroken=true` with a
   consecutive-failure counter. The pool only trips after
   `consecutiveFailureThreshold` deaths (default `max(3, poolSize)`) with
   no successful job in between. A successful job resets the counter so
   transient bursts of bad files don't escalate.

3. **Session-scoped file quarantine** — paths identified as the in-flight
   file at the moment of a worker death are added to a `Set<string>` on
   the pool. `dispatch()` filters quarantined items up front (they never
   reach a worker again this pool lifetime). Exposed via the new
   `WorkerPool.getQuarantinedPaths()` so callers can log/route them.
   `processParsing` surfaces the per-chunk quarantine summary alongside
   the existing fallback-exclusion log.

4. **Authoritative in-flight tracking** — `parse-worker.ts` emits
   `{type:'starting-file', path}` before each file. The pool tracks this
   per slot and uses it for crash attribution, falling back to the
   `items[lastProgress]` heuristic only when no starting-file has been
   observed (very-early crash, older worker build). Closes the
   reorder/race concerns raised by reviewers C1 and R3 in the earlier
   review run.

5. **Per-job cumulative timeout budget** — each `WorkerJob` tracks the
   total wall time spent across attempts/splits/retries. When the budget
   is exhausted (default 5x `subBatchIdleTimeoutMs`), the pool surfaces
   the in-flight path instead of letting exponential backoff balloon
   into multi-hour stalls.

Cross-layer wiring: a new `wakeIdleSlots` helper kicks any non-busy live
slot when items are requeued (after a death or split-retry), so a dropped
slot doesn't strand work in the queue. `recoverAndResume` consolidates
the per-job teardown shared by the three in-pool death sites (`error`,
`exit`, msg-channel `error`).

New env knobs: `GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT`,
`GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS`,
`GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD`.
New `WorkerPoolOptions.workerFactory` injection point for unit tests.

Tests: 12 new unit tests using a FakeWorker mock cover quarantine
seeding, slot-respawn, slot-drop after budget, breaker trip + reset,
and quarantine filtering. Plus option-resolution tests for the three
new env vars. All 19 worker-pool/-fallback/-options tests pass; full
unit suite 6040 passed / 30 skipped / 0 failed.

* fix(workers): apply code-review fixes (12 findings)

Walks through every finding from ce-code-review run
20260519-094648-3549cf5e. All 12 picked Apply.

Critical:
- F1 — Layer 5 cumulative-timeout exhaustion no longer silently drops
  the rest of the job. `requeueRemainder` is now invoked before
  `handleWorkerDeath` in both Layer 5 and singleton-final-fail give-up
  paths so non-quarantined items get re-tried by another worker.
- F2 — idle-timer recovery overhaul. `!shouldContinue` branch no
  longer calls `replaceWorker` (double-spawn race with the
  `handleWorkerDeath` inside `requeueAfterTimeout`). `shouldContinue`
  branch now enforces `maxRespawnsPerSlot` before respawning, closing
  the budget-bypass for the timeout-retry path. Also fixes premature
  `maybeDone` by simplifying the bookkeeping.
- F3 — `requeueRemainder` no longer pre-charges `cumulativeTimeoutMs`
  by `job.timeoutMs`. The death itself consumed no budget, so the
  next `requeueAfterTimeout` was double-billing the first attempt.
- F4 — `WorkerPool.getQuarantinedPaths` is now optional on the
  interface, matching the defensive `?.()` call site and the existing
  mocks. Removes the contract-vs-callsite contradiction.
- F5 — per-job unattributed-death tracking. When a worker dies with
  no exclusion attribution, `requeueRemainder` tracks death count per
  `startIndex`. First time: re-queue intact. Second time: quarantine
  items[0] as best guess, or drop the job entirely when items lack
  paths. Bounds the death loop the original design admitted to.
- F6 — per-slot consecutive-failure counter. Replaces the pool-wide
  scalar so a chronically-failing slot trips the breaker on its own
  streak instead of being masked by another slot's successes.

Smaller:
- F7 — exhaustiveness `never` check on `WorkerOutgoingMessage` union.
- F8 — recursive `runWorker` on fully-quarantined jobs converted to
  a while-loop.
- F9 — `tripBreaker` calls `reject(err)` BEFORE awaiting
  `worker.terminate()`. A stuck terminate no longer blocks the caller.
- F10 — `parsing-processor.ts` quarantine log de-duplicates per pool
  instance via a `WeakMap`. Only newly-quarantined paths are logged
  in each chunk; the per-chunk count still surfaces via progress.
- F11 — extract `firstPath` local in `requeueAfterTimeout`; eliminates
  double `itemPath` call and the `unknown as string` cast.

Tests (F12, 6 new):
- crash-error event path (errorHandler).
- F5 drop-branch coverage via items without `.path`.
- Common-case unattributable crash falling back to items[0] heuristic.
- `replaceWorker` startup failure (workerFactory emits 'exit' before
  'online').
- All-slots-dropped breaker trip.
- `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS` env override.

Residual gap (deferred): no unit test exercises the Layer 5
cumulative-budget runtime path — requires fake-timer interleaving
with FakeWorker that's too brittle for this iteration. Tracked.

Unit suite: 257 files / 6056 passed / 30 skipped / 0 failed.

* test(workers): integration tests for resilience layers + fix requeue-after-timeout flow

Adds 6 new real-worker integration tests covering the PR #1693
resilience layers + fixes 3 follow-on bugs surfaced while writing them.

New integration coverage (real worker threads + temp fixture scripts):

- `respawns the slot after worker process.exit and finishes the work on
  the replacement` — exercises Layer 1 auto-respawn + Layer 3 quarantine
  through real IPC.
- `attributes exactly via authoritative starting-file message on worker
  crash` — Layer 4 end-to-end: starting-file message → exact quarantine
  attribution (not the items[0] heuristic).
- `quarantine filters subsequent dispatches without sending to a worker`
  — second dispatch's sub-batch payload audited via filesystem; the
  quarantined path is never sent across the message channel.
- `drops a slot after maxRespawnsPerSlot and continues on the survivor`
  — 2-slot pool, slot dies twice past budget, survivor finishes
  re-queued remainder.
- `trips the circuit breaker on cascading per-slot consecutive failures`
  — single-slot pool, dies on every job, breaker trips after
  consecutiveFailureThreshold with WorkerPoolDispatchError carrying
  the cumulative quarantine.
- `survives a worker error event (uncaught throw) the same as a
  process.exit` — validates recoverAndResume on the errorHandler path
  via a real worker `throw` (not just process.exit).

Bug fixes uncovered while writing these tests:

1. **Stack-overflow recursion in runWorker's no-worker branch** —
   `if (!worker) { ...; wakeIdleSlots(); maybeDone(); }` recursed
   indefinitely when multiple slots were mid-respawn simultaneously
   (wakeIdleSlots → runWorker → no worker → wakeIdleSlots → …).
   Removed the wakeIdleSlots call: the slot's own respawn IIFE owns
   runWorker post-respawn, and other slots will pick up work via
   finishJob's runWorker.

2. **requeueAfterTimeout dispatched work before respawn completed** —
   the F2 fix had `requeueAfterTimeout` `void`-discarding
   `handleWorkerDeath`, so the `!shouldContinue` IIFE had no way to
   know when the respawn finished. New design: `requeueAfterTimeout`
   returns a `TimeoutDecision` discriminated union; the IIFE owns
   the death-and-respawn-and-dispatch orchestration in an async
   closure so it can `await handleWorkerDeath` and then call
   `runWorker` deterministically.

3. **Stalled-singleton + protocol-error + replacement-startup-crash
   tests** had stale contracts predating the resilience refactor. The
   stalled-singleton no longer rejects (it quarantines + resolves
   `[]`); the protocol-error rejection message now mentions
   "circuit breaker tripped"; the replacement-startup-crash test
   documents the known `waitForWorkerOnline` race (online fires
   before the worker's main script runs, so a top-level throw looks
   like a successful spawn) — the test asserts the file is
   quarantined via the second-idle-timeout give-up path.

Full suite: 334 files / 8982 passed / 43 skipped / 0 failed (second
run; first run had a Vitest-reported flake from an uncaught worker
exception bleeding into the test report — repeated runs are clean).

* perf(workers): raise pool cap to cores-1 + defer per-chunk extraction to keep workers busy

User reported 4-5% CPU utilization on a multi-core machine during
ingestion. Two structural reasons:

1. **Pool cap.** `createWorkerPool` resolved size as
   `Math.min(8, max(1, os.cpus().length - 1))` — a 16-core box got 8
   workers (50% theoretical max). U1 lifts the default to
   `min(16, max(1, cores - 1))`, exposes `GITNEXUS_WORKER_POOL_SIZE`
   env override, and adds `--workers <N>` CLI flag (`0` disables the
   pool for sequential fallback).

2. **Per-chunk extraction serialized the loop.** Per chunk:
   dispatch → await workers → main-thread `processImportsFromExtracted`
   + `processHeritageFromExtracted` + `processRoutesFromExtracted`
   + `synthesizeWildcardImportBindings` + `seedCrossFileReceiverTypes`
   → next chunk dispatch. Workers sat idle through every extraction
   block. U2 (revised from the plan's pipelined-chunks design) defers
   these passes to a single end-of-loop batch. Chunk loop becomes
   parse + merge + accumulate. Resolution sees strictly-more-info
   (full repo graph) so cross-chunk import/heritage targets resolve at
   least as well as before. Memory cost: `deferredWorkerImports`
   accumulates across chunks; bounded by total file count, acceptable.

Plan deviation note: the plan called for an in-flight chunk pipeline
(N concurrent dispatches with bounded memory). That design needed
either a `processParsing` API refactor or duplicating its catch-block
fallback in `parse-impl`. The deferred-extraction approach delivers
the same "workers stay busy" outcome with much smaller surface area
and zero changes to `processParsing`. The `GITNEXUS_PARSE_CHUNK_CONCURRENCY`
env var documented in U2 of the plan is therefore not implemented in
this commit; if memory growth from `deferredWorkerImports` becomes
a problem at very-large-repo scale, a bounded sliding-window variant
can land as a follow-up.

Tests:
- New `test/unit/analyze-worker-pool-size.test.ts` covers --workers
  validation (5 invalid inputs rejected with exit code 1 + clear
  error; valid integers set the env var; `--workers 0` routes to
  sequential).
- Extended `worker-pool-resilience.test.ts` with `resolveAutoPoolSize`
  scenarios: env override, env=0, env above cap, invalid env fallback,
  auto-formula match, integer return type.
- Full unit suite: 6097 / 6127 passed / 30 skipped / 0 failed.
- Full integration suite (second run): 77 / 78 passed / 1 skipped /
  0 failed. First run had a known cosmetic flake from an uncaught
  worker exception bleeding into the test reporter.

Resilience contract from PR #1693 preserved: per-slot respawn budget,
circuit breaker, quarantine, authoritative in-flight tracking,
cumulative timeout budget — all unchanged.

New env vars surfaced in --help: GITNEXUS_WORKER_POOL_SIZE,
GITNEXUS_PARSE_CHUNK_CONCURRENCY (reserved for future bounded
pipelining).

* docs(readme): document --workers CLI flag

* feat(workers): add getStats() and per-chunk throughput logging

* test(workers): cleanup leaked temp-dirs and drop duplicate option-resolution block

- Add afterEach to worker-pool-resilience.test.ts cleaning up the per-test temp
  directory created by beforeEach (~25 stale dirs per CI run previously).
- Delete the duplicated describe('worker pool option resolution', ...) block.
  Verified the first block (lines 490-532) is a strict superset (includes the
  GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS env test the second block omitted),
  so deletion loses no test coverage.

* feat(cli): thread --workers via PipelineOptions + snapshot/restore CLI env

Resolves PR #1693 review B2 (env-var leak in long-running hosts):

- --workers is now threaded through AnalyzeOptions -> runFullAnalysis
  -> PipelineOptions.workerPoolSize -> createWorkerPool's explicit
  poolSize arg, bypassing the GITNEXUS_WORKER_POOL_SIZE env channel.
  The env var remains as a back-compat fallback inside resolveAutoPoolSize
  for operators who set it directly.
- analyzeCommand and wikiCommand snapshot the GITNEXUS_* env vars they
  mutate at function entry and restore them in finally. Inner *Impl
  extraction keeps the diff surgical (no body re-indent). process.exit(0)
  on the CLI success path still terminates the process; restoration
  matters for programmatic callers (tests, long-running hosts) reaching
  early-return paths or the alreadyUpToDate fast path.
- Tests updated to assert the new behavior:
    analyze-worker-pool-size.test.ts: workerPoolSize flows through
      runFullAnalysis options; env is not mutated; back-to-back calls
      see their own values, not the previous call's leak.
    analyze-worker-timeout.test.ts: env IS set during the runFullAnalysis
      call (captured via mockImplementation) and restored after, proving
      the timeout reaches downstream while the leak fix holds.
- Also addresses L4: afterEach NODE_OPTIONS restore so back-to-back test
  runs don't accumulate --max-old-space-size=8192 tokens.

Addresses PR #1693 review B2 (blocker) and L4 (test polish).

* feat(workers): harden worker lifecycle (messageerror + availableParallelism + ready handshake)

Resolves PR #1693 review H1, H2, M4:

H1 - messageerror handler at every dispatch site
  V8 deserialization failure on postMessage previously left the message
  silently lost; the pool would wait out the idle timeout (default 30s)
  instead of treating it as worker death. The dispatch loop now wires
  worker.once('messageerror', ...) alongside error/exit and routes through
  recoverAndResume so the existing per-slot respawn budget, in-flight
  file attribution, and circuit-breaker layers fire as designed.

H2 - resolveAutoPoolSize uses os.availableParallelism()
  Mirrors the pattern at capabilities.ts:85 (defaultEmbeddingThreads).
  os.cpus().length returns the host CPU count, which over-sizes the pool
  on cgroup-limited containers, taskset-restricted runtimes, and CI
  runners with explicit CPU quotas. Falls back to os.cpus().length on
  Node < 18.14.

M4 - worker-side ready handshake replaces online-trust
  parse-worker.ts now emits {type: 'ready'} after all top-of-script
  initialization completes, BEFORE the message handler is attached. The
  pool's renamed waitForWorkerReady listens for this message under a
  bounded WORKER_READY_TIMEOUT_MS (5s) budget instead of trusting Node's
  online event - which fires when the worker thread starts, BEFORE the
  script body runs, letting init crashes slip past pool startup. ready
  is added to WorkerOutgoingMessage with an exhaustiveness-checked
  no-op branch in the dispatch handler (defensive: the message is
  consumed by waitForWorkerReady before dispatch handlers attach).
  messageerror is wired into waitForWorkerReady the same way.

Test scaffolding:
  - FakeWorker emits {type: 'ready'} in addition to 'online' so
    replacement workers in unit tests don't hit the 5s budget.
  - Integration test ad-hoc worker scripts go through a writeReadyWorker
    helper that prepends the ready handshake. Tests intending to script
    "crash BEFORE ready" can bypass the helper.

61/61 worker-pool unit tests pass; 28/28 integration tests pass.

* feat(parse-impl): monotonic progress + verbose-gated throughput log + seed-before-build

Resolves PR #1693 review M2, M3, L1, L5 in a single parse-impl.ts pass:

M2 - Monotonic progress through deferred phase (no more "stuck at 82%")
  Previously the deferred resolution stages (imports, heritage, routes,
  calls) all emitted percent: 82 — the UI looked frozen for the duration
  of the deferred work, which on large repos is several seconds to minutes
  and visually identical to the hang PR #1693 set out to fix.
  Redistributed:
    parse phase:  20-70 (was 20-82)
    imports:      70-75
    heritage:     75-80
    routes:       80-85
    calls:        85-95
  Each deferred stage now advances through its own band via the existing
  per-batch progress callback. Skipped stages (zero deferred input) leave
  their band as a no-op jump - the next stage still starts at its own
  band, preserving strict monotonicity. The "no parseable files" early
  return now jumps to 95 (was 82), and the duplicate "Parsing N files..."
  announcement is suppressed when totalParseable === 0 to avoid a
  non-monotonic 95 -> 20 regression that pre-existed (uncovered by the
  new monotonic test).

M3 - Throughput log gated on `--verbose`, not just NODE_ENV=development
  The per-chunk files/s log was gated on `isDev`, so operators running
  `gitnexus analyze --verbose` in a production install never saw it.
  Now fires when (isDev || isVerboseIngestionEnabled()) — matches the
  documented promise that `--verbose` shows tuning observability.

L1 - Typo rename: `chunkChunkStartMs` -> `chunkStartMs`

L5 - `buildExportedTypeMapFromGraph` runs BEFORE `seedCrossFileReceiverTypes`
  Previously the seeding branch was reached with `exportedTypeMap.size === 0`
  in the worker path (the map was only built far below, AFTER the seeding
  branch), so the seed dead-coded itself silently and call resolution
  never got the cross-file receiver-type enrichment. Now the map is
  populated from the in-progress graph before the seed call; the
  post-parse builder remains as a defensive sequential-path fallback,
  guarded by `size === 0` so we don't pay the cost twice on the worker
  path. Net win: cross-file CALLS edges that previously had no receiver
  type now get enriched.

New test: parse-impl-progress-monotonic.test.ts
  Asserts the emitted percent stream is strictly non-decreasing across
  the parse + deferred phases, and that the deferred band (>=70) is
  actually reached. Also pins the "no parseable files" path to exactly
  [95] so the 95 -> 20 regression we just fixed can't re-emerge.

* feat(parse-impl): bounded chunk concurrency via file-pre-fetch pipeline

Resolves PR #1693 review B1 (GITNEXUS_PARSE_CHUNK_CONCURRENCY documented
in --help but unimplemented).

The chunk loop now pre-fetches chunk file contents up to
`parseChunkConcurrency` chunks ahead of the worker-dispatch cursor so
disk I/O overlaps with worker compute. Worker dispatch itself stays
serial because WorkerPool.dispatch is not reentrant — concurrent calls
would race on the shared per-slot busy/in-flight state, regressing the
hang/resilience work this PR is built on. The pre-fetch path is the
honest interpretation of "concurrent in-flight parse chunks" that the
help text advertises: I/O overlap, not parallel worker dispatch.

Concurrency value resolution:
  1. PipelineOptions.parseChunkConcurrency (threaded from CLI)
  2. GITNEXUS_PARSE_CHUNK_CONCURRENCY env var
  3. Default 2 (matches the help text)

F4 (wildcard-synthesis ordering) is preserved: deferred-state
aggregation runs in chunkIdx order because the for-loop iterates
sequentially after awaiting each chunk's pre-fetched contents.
Cross-chunk processors (processImportsFromExtracted,
synthesizeWildcardImportBindings, etc.) still run only after all
chunks complete — they see deterministic input regardless of
file-read completion order.

Concurrency=1 produces behavior identical to the pure-serial loop;
that's the regression baseline.

New test: parse-impl-chunk-concurrency.test.ts
  - Asserts graph output is identical (nodeCount + relationshipCount)
    between parseChunkConcurrency=1 and =2 — the critical correctness
    invariant. Exact .toBe(N) comparisons per DoD §2.7 (the second run's
    counts must equal the first run's exactly).
  - Pins specific fixture symbols (foo/bar/Baz) under both
    parseChunkConcurrency=1 and the env-fallback (3) path.
  - Env-fallback test confirms GITNEXUS_PARSE_CHUNK_CONCURRENCY is
    honored when the option is undefined.

* test(workers): pin cumulative-timeout exhaustion behavior

Resolves PR #1693 review M6: the existing resilience suite asserts only
the *default value* of maxCumulativeTimeoutMs (5x subBatchIdleTimeoutMs),
not that dispatch actually aborts the offending job when the cumulative
wall-clock budget is exhausted. Without this test, a future refactor
could remove the exhaustion branch in requeueAfterTimeout and the suite
would stay green while the pool sat in retry loops for an hour on a
real production stall.

Scenario:
  subBatchIdleTimeoutMs    = 100ms
  timeoutBackoffFactor     = 10
  maxCumulativeTimeoutMs   = 300ms

Single file, HangingWorker that never responds. First attempt times
out at 100ms (cumulative=100). The next backoff (1000ms, cumulative
1100ms) exceeds the 300ms cap, so requeueAfterTimeout returns
give-up on the first timeout retry and the file goes to the session
quarantine. Asserts:
  - pool.getQuarantinedPaths() includes 'src/stuck.ts' after dispatch
  - if dispatch rejected, the error is a WorkerPoolDispatchError
    (the typed surface that routes to sequential fallback)

Uses a local minimal HangingWorker double rather than the full
action-scripted FakeWorker from worker-pool-resilience.test.ts —
the inverse pattern (always hang) doesn't need the scripted-action
machinery and keeps the test file focused on the one behavior.

* docs(readme): add environment-variables reference table

Resolves PR #1693 review L6: operator-facing env vars were either
mentioned inline (GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS) or only
documented via `gitnexus --help`, with no single place to look up
the full set. The new "Environment variables" subsection under the
Quick Start CLI block lists every operator-facing knob with default,
effect, and tuning guidance, matching the names in cli/index.ts
addHelpText post-U2 / U1.

Covers:
  GITNEXUS_WORKER_POOL_SIZE           (--workers)
  GITNEXUS_PARSE_CHUNK_CONCURRENCY    (newly real per U1)
  GITNEXUS_VERBOSE                    (--verbose)
  GITNEXUS_MAX_FILE_SIZE              (--max-file-size)
  GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS (--worker-timeout × 1000)
  GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES
  GITNEXUS_CHUNK_BYTE_BUDGET
  GITNEXUS_NO_GITIGNORE
  GITNEXUS_SKIP_OPTIONAL_GRAMMARS

CLI flag vs env-var precedence is stated explicitly (CLI > env > default)
so operators running long-lived hosts (MCP server, eval-server) know
which channel wins.

* test(workers): pin quarantine path round-trip and non-normalization contract

Resolves PR #1693 review M5 (Windows quarantine path-normalization
coverage). worker-pool.ts quarantines paths via a Set<string> keyed by
exact string equality. The existing suite never asserted this contract,
which lets a future "helpfully normalizing" refactor on one side of the
pipeline (caller, worker, or pool) silently break quarantine filtering
on Windows.

This file pins the contract from both directions:

1. Round-trip: a path the caller dispatches with backslashes
   (src\bad.ts) flows through starting-file -> death -> quarantine ->
   next-dispatch filter verbatim. The replacement worker never sees the
   re-dispatched bad path because the pool's pre-dispatch filter
   short-circuits it.

2. Non-normalization: quarantining src\poison.ts does NOT filter
   src/poison.ts. Whoever changes that contract has to update this test
   alongside (the load-bearing assertion catches accidental
   path.normalize() calls in the quarantine path).

Runs on every platform — the path strings are test-injected, so the
test exercises the same code path regardless of the host's path.sep.
Used a self-contained FakeWorker that emits {type:'ready'} for U3's
waitForWorkerReady handshake, so the test doesn't depend on the larger
worker-pool-resilience.test.ts harness.

* test(typescript): pin capture-anchor rewrite invariants (B5 regression)

Resolves PR #1693 review B5: the captures.ts ancestor-walk rewrite
(findSelfOrAncestorOfType[s] + pickFirstNode replacing the prior
findNodeAtRange-from-root path) was semantically equivalent to its
predecessor per Lane 4 of the production-readiness review, but the
existing typescript-captures.test.ts didn't pin the specific sharp
edges where an over-aggressive walk would silently break captures.
This file does.

Each test exercises a capture class whose anchor type is one the
rewrite explicitly handles:

  - member call obj.foo() -> @reference.call.member (call_expression
    anchor walks to self)
  - dynamic import import("./helper") -> raw @import.dynamic gets
    decomposed by splitImportStatement into @import.statement with
    @import.kind=dynamic + @import.source stripped of quotes
  - JSX <Foo /> in .tsx -> @reference.call.free emitted (TSX query
    pattern, query.ts:899-905) but @declaration.parameter-count is
    NOT synthesized because findSelfOrAncestorOfType('call_expression')
    returns null on a jsx_self_closing_element anchor. Pre-rewrite the
    range lookup also returned null. Pinning this contract catches
    accidental "walk JSX -> outer call" refactors.
  - constructor `new Foo(1,2)` -> @reference.call.constructor (new_expression
    anchor walks to self)
  - named/namespace import + re-export -> @import.statement (one each)
  - class method override -> @declaration.method per class, no collapse
  - member read obj.foo (no call) -> @reference.read.member

All assertions use exact .toBe(N) per DoD §2.7.

* test(parse-impl): pin multi-chunk graph equivalence under deferred extraction

Resolves PR #1693 review B4: the deferred-extraction reorder (moving
processImportsFromExtracted / Heritage / Routes / Wildcard /
ReceiverTypes from per-chunk to end-of-loop) was proven observably
equivalent by Lane 4 of the production-readiness review. Until now,
the existing suite never asserted cross-chunk graph equivalence,
which lets a future refactor that accidentally tightens the per-chunk
vs end-of-loop coupling silently break cross-chunk resolution.

This test forces multi-chunk parsing on a small fixture by setting
GITNEXUS_CHUNK_BYTE_BUDGET=64 BEFORE the parse-impl module loads
(the budget is captured at module load via vi.resetModules — a future
move to function-scope env reads is U14 in Phase 2). Then runs the
same fixture under a 10MB budget (single chunk) and asserts the two
graphs are byte-identical: same nodeCount, same relationshipCount,
exact .toBe(N) per DoD §2.7.

Fixture: 3-file class hierarchy with cross-file inheritance — Animal
(a.ts) -> Dog extends Animal (b.ts) -> makeDog returns Dog (c.ts).
Forces the resolver to chain imports + heritage across chunks. A
second test pins specific symbol names (Animal, Dog, makeDog, speak,
bark) in the multi-chunk graph so a regression in chunk-boundary
resolution surfaces as a missing-symbol failure with a specific
diagnostic instead of a bare count mismatch.

* test(parse-impl): wall-clock integration pinning multi-chunk pipeline (B3)

Resolves PR #1693 review B3 — the final P0/P1 merge blocker. With this
test, all five doc-review blockers (B1-B5) are pinned by regression
coverage.

The PR's headline claim is "analyze no longer hangs on TS-root-shaped
loads". The existing suite pins each resilience layer (worker-pool-
resilience.test.ts), the deferred-extraction equivalence (U7), and
the chunk-concurrency contract (U1). What was missing: a single
end-to-end run that exercises the full chunked parse-and-resolve
path on a multi-chunk fixture, BOUNDED by a wall-clock budget so a
regression that re-introduces the hang fails this test loudly via
timeout rather than slipping past as a count drift.

Implementation:
  - 17-file synthetic fixture: 15 small modules (one function each),
    one "realistic dense" complex.ts (30 functions + class + interface),
    and an index.ts re-exporting them. Forces cross-chunk import
    chains.
  - GITNEXUS_CHUNK_BYTE_BUDGET=64 via vi.resetModules forces multi-chunk
    parsing on the small fixture.
  - Promise.race with 30s timeout: a hang fails as
    "exceeded WALL_CLOCK_BUDGET_MS — likely the hang B3 was meant to
    prevent", not as a bounds-only inequality (DoD §2.7 distinction —
    hang-detector via exception, not regression-mask via inequality).
  - Exact .toBe(true) assertions on specific expected symbols
    (fn0..fn14, Service, Config, configure, describe, complex0/15/29)
    so a silent mid-chunk crash that exits 0 without producing graph
    data also fails this test, not just the hang case.

Scope: runs the sequential-fallback path (skipWorkers: true) because
the full real-worker scenario requires a built dist/parse-worker.js
and ~60s wall-clock per run — appropriate for a CI-integration job,
not vitest. The load-bearing invariants pinned here catch the bulk
of B3's concern; the dist-worker swap is a Phase 2 follow-up
documented in the file header.

* refactor(parse-impl): move chunk-byte-budget env read to function scope

Resolves PR #1693 review F7 / U14: pre-U14, `CHUNK_BYTE_BUDGET` was a
module-load IIFE constant that captured `GITNEXUS_CHUNK_BYTE_BUDGET`
once and froze the value for the module's lifetime. That defeated
per-call option threading (a future
`PipelineOptions.chunkByteBudget` was silently no-op'd because the
function body read the frozen module-level constant) AND forced tests
to use `vi.resetModules` to vary chunk layout. The U7
deferred-extraction test and the U6 multi-chunk integration test
both used the workaround.

After this change:

  - `DEFAULT_CHUNK_BYTE_BUDGET = 2 * 1024 * 1024` stays as a
    module-level constant — purely a default, no env access.
  - `resolveChunkByteBudget(options)` runs per call: option wins,
    then env, then default. Same options-first/env-fallback/default
    pattern as resolveAutoPoolSize and the U1 parseChunkConcurrency
    resolver — keeps the ingestion code's configuration model uniform.
  - `PipelineOptions.chunkByteBudget?` added with documentation that
    threading through options lets long-running hosts (eval-server,
    MCP daemon) size per-call without leaking process.env state
    across analyze invocations.

New test (parse-impl-env-reads.test.ts) pins all four behaviors:
  1. option-first: option present + env present -> option wins
  2. env-fallback: option absent + env present -> env wins
  3. default-fallback: both absent -> 2 MB default
  4. per-call: two back-to-back runs in the same vitest worker with
     different chunkByteBudget option values observe their OWN values,
     proving the module-load freeze is gone (no vi.resetModules in
     this test — that's the invariant being verified).

All four assertions use exact `.toBe(N)` per DoD §2.7. The chunk
count is observed by parsing the `Parsing chunk X/Y` progress message
stream — a stable proxy that doesn't require exposing internal
parse-impl counter state.

Note: U7 and U6 tests still use `vi.resetModules` because they were
written before this change. A follow-up cleanup could simplify those
tests (drop the resetModules dance, pass chunkByteBudget via options),
but they pass as-is so this commit doesn't touch them.

* feat(workers): per-slot generation counter for late-event protection (U12)

Adds a monotonic per-slot generation counter to createWorkerPool's
state. Each successful worker replacement (replaceWorker) bumps the
slot's counter exactly once — atomically with the workers[slotIndex]
swap, so observers (getStats) see the new (worker, generation) pair
consistently. Handler closures in the dispatch loop capture the
slot's generation at attach time and short-circuit when they fire
on a stale generation.

In the current implementation, cleanup() synchronously removes
listeners on a Worker instance the moment a death is observed, so
no listener naturally fires on a stale generation — the guard is a
defensive layer protecting against any future refactor that loosens
cleanup() ordering or re-attaches handlers across the swap. The
load-bearing observable is the slotGenerations[] array exposed via
WorkerPoolStats so operators (and tests) can confirm a slot was
actually replaced and not just the same worker recycled.

Implementation:
  - const slotGenerations: number[] = new Array(size).fill(0) in
    createWorkerPool's per-pool state, alongside respawnCount and
    consecutiveFailuresPerSlot.
  - replaceWorker: slotGenerations[workerIndex]++ AFTER the
    workers[workerIndex] = replacement swap (only on the success
    branch — drop-slot paths leave the counter unchanged).
  - runWorker dispatch loop: const slotGen = slotGenerations[workerIndex]
    captured before handler attachment; every handler (handler /
    errorHandler / exitHandler / messageErrorHandler) starts with
    `if (slotGenerations[workerIndex] !== slotGen) return`.
  - WorkerPoolStats gains `readonly slotGenerations: readonly number[]`.
  - getStats() returns slotGenerations.slice() so callers can't mutate
    pool state by writing to the returned array.

Two existing toEqual snapshots in worker-pool-resilience.test.ts
extended with the new slotGenerations field (both expect all-zeros —
neither test scenario triggers a respawn).

New test file (worker-pool-slot-generation.test.ts, 4 tests):
  1. Fresh pool: every slot at generation 0.
  2. Successful crash + respawn: generation bumps to 1 exactly once.
  3. Crash that drops the slot (maxRespawnsPerSlot:0): generation
     stays at 0 because no successful respawn happened. The dispatch
     rejection on breaker trip is the expected outcome here; the
     load-bearing assertion is the post-rejection stats.
  4. Multi-slot independence: one slot crashing bumps only that
     slot's generation, not the other. Order-independent via sort()
     because the round-robin assignment isn't pinned by contract.

All assertions exact .toEqual / .toBe per DoD §2.7.

* docs(bench): add parse-throughput benchmark scaffold (R13)

Resolves PR #1693 review R13 (benchmark artifact requirement).

Creates `gitnexus/bench/parse-throughput.md` documenting:

- Synthetic fixture spec (same shape as the U6 integration test, so
  CI smoke baseline and ad-hoc benchmark exercise the same paths).
- What to measure (wall-clock, peak heap, chunk count, getStats
  snapshot) and the hardware-shape metadata to record alongside.
- Harness recipe — vitest + env-var overrides to exercise sequential
  fallback vs worker-pool paths.
- Latest-measurement table with placeholder rows for the three paths
  (sequential, workers+concurrency, workers single-threaded) and an
  explicit "Status: scaffold — fill in before merging" callout. The
  U6 test's observed ~6 s wall-clock is captured as a smoke-baseline.
- Operator-tuning quick reference cross-linked to the README env-var
  section (U11) so the doc is actionable without re-reading the PR.
- "What this benchmark does NOT measure" section explicitly scoping
  the artifact's limits (synthetic ≠ real-repo, throughput-only ≠
  resilience-tested, Phase 3 IPC repack row reserved for U16-U17).

Mitigates the doc-review SG5 "static doc drift" concern via:
  1. Explicit "regenerate this file before merging" callout at the top.
  2. Self-contained methodology so anyone can re-run the numbers.
  3. Cross-links to the U6 integration test that already bounds the
     wall-clock as part of the CI suite — so "is it still completing?"
     is regression-tested even if the numbers in this doc drift.

The standalone harness script (`bench/scripts/parse-throughput.ts`)
remains a stretch goal per the original plan. The U6 vitest with
verbose ingestion logs covers the primary observability gap until
the standalone harness lands.

* perf(parse-impl): free deferred-extraction arrays after consumption (U15 lightweight M1)

PR #1693 review M1 noted that the deferred-extraction accumulator
arrays (`deferredWorkerImports`, `deferredWorkerCalls`,
`deferredWorkerHeritage`, `deferredConstructorBindings`,
`deferredAssignments`) were retained until function return, making
peak accumulator memory O(repo) instead of O(in-flight stage).

This commit implements the LIGHTWEIGHT version: free each array
immediately after its last consumer drains/reads it, dropping peak
accumulator memory progressively through the deferred-extraction
stages. The structural per-chunk streaming variant (the original
U15 framing) is deliberately deferred — the doc-review's adversarial
reviewer (A4) flagged it as defending unmeasured memory pressure,
and the simpler array-clearing captures the bulk of the benefit
without committing to a scheduling-strategy decision (microtask vs
parallel extractor task vs worker-side) that profile data should
inform.

Clears added:

  1. After `processImportsFromExtracted` (the sole consumer of
     `deferredWorkerImports`): clear the imports array before
     the heavier heritage/calls stages run.
  2. After `buildHeritageMap` (the LAST consumer of the raw
     `deferredWorkerHeritage` records — processCallsFromExtracted
     reads from the derived `fullWorkerHeritageMap` instead):
     clear the heritage array before the call-resolution stage.
  3. After `processAssignmentsFromExtracted` (the joint last
     consumer with processCallsFromExtracted for the calls/
     bindings/assignments triple): clear all three before
     downstream graph-build / scope-resolution uses its own
     working memory.

Arrays returned in the function result object (allFetchCalls,
allExtractedRoutes, allDecoratorRoutes, allToolDefs, allORMQueries,
allParsedFiles) intentionally stay live — downstream consumers
need them.

Graph-output equivalence is preserved (U7 multi-chunk equivalence
test passes — the clears happen AFTER each array's last consumer
has copied data into the graph or derived structures).

* feat(workers): introduce protocol.ts wire-format module (U16, IPC scaffold)

Defines the binary frame for worker-thread IPC as an isolated, fully-tested
module. Production wiring is deferred to U17 — shipping the wire-format
contract first de-risks the migration by establishing a single source of
truth for the byte layout. Resolves the scaffold half of PR #1693 review
R12.

Wire layout (per message, single buffer):

  +---------+-----------+---------------------+
  | tag     | length    | payload bytes …     |
  | 1 byte  | 4 bytes   |                     |
  +---------+-----------+---------------------+

  tag    : MessageTag enum value (0x01 DispatchJob ... 0x08 Ready)
  length : little-endian uint32 byte count for the payload region
  payload: UTF-8 JSON-encoded value, possibly "null"

Why JSON for the body (rather than per-shape binary encoders): the
doc-review adversarial reviewer (A2) flagged that a true per-shape
binary encoder for the result message — which carries nested
heterogeneous extracted-call / import / heritage / route arrays —
would be 500-1500 LOC and a substantial maintenance burden. The
honest perf win the IPC repack targets is moving file CONTENTS via
ArrayBuffer transferList (zero-copy ownership transfer for the
largest single piece of state in any message). That win is captured
by U17 layering transferList over the bulk file-content payload while
keeping this module's framing for the surrounding metadata. If U18
benchmark data shows the JSON body is itself a bottleneck after U17
lands, a follow-up unit can swap to per-shape binary encoding behind
the same encodeMessage / decodeMessage surface without changing the
frame.

API:
  - MessageTag (const object): stable byte tags 0x01..0x08
  - PROTOCOL_HEADER_BYTES = 5
  - ProtocolDecodeError extends Error: distinct class so U17's
    pool-side handler can route protocol violations through the
    existing messageerror recovery layer (U3 H1) distinctly from
    other failure classes
  - encodeMessage(tag, payload): Buffer
  - decodeMessage(buf): { tag, payload }
  - Uses Buffer#subarray instead of the deprecated Buffer#slice

Tests (18, all exact-equality per DoD §2.7):
  - byte layout (tag at offset 0, length LE uint32 at offset 1)
  - empty/null payload encodes to 5-byte header + 4-byte "null" body
  - round-trip for every MessageTag with representative payloads
  - non-ASCII path string (UTF-8 byte-length boundary)
  - 9 MB payload (well past the existing 8 MB sub-batch budget)
  - decode errors surface as ProtocolDecodeError, not generic Error:
      * buffer < header size
      * tag outside valid range
      * declared length exceeds buffer
      * payload bytes are not valid JSON
  - error class name is preserved through prototype chain so callers
    can `err instanceof ProtocolDecodeError` reliably

* refactor(workers): extract quarantine into its own module (U13 partial)

Honest partial U13: extract the quarantine resilience layer (Layer 3
of the 5-layer model) into a dedicated module with a small explicit
interface. The full 5-module split that the original plan named was
flagged by doc-review A10 as abstraction-without-multi-consumer-demand
("Each has exactly one consumer: worker-pool.ts. None of these layers
is imported elsewhere in the codebase pre-extraction, and the plan
doesn't identify any future consumer.") This commit ships the smallest
self-contained layer as a named module to validate the factory +
interface pattern with minimal risk. The remaining four layers
(respawn-budget, cumulative-timeout, circuit-breaker, slot-attribution)
stay inline until a real second consumer emerges (e.g., a non-parse
worker pool that reuses the same resilience layers).

Module shape (`workers/quarantine.ts`, ~30 LOC):

  interface Quarantine {
    add(path: string): void;
    has(path: string): boolean;
    snapshot(): string[];   // defensive copy
    readonly size: number;  // getter, reflects state at access time
  }
  function createQuarantine(): Quarantine

Replaces in `worker-pool.ts`:
  - `const quarantined: Set<string> = new Set()` -> `createQuarantine()`
  - `quarantined.has(p)`            -> `quarantine.has(p)` (2 sites)
  - `quarantined.add(p)`            -> `quarantine.add(p)` (2 sites)
  - `quarantined.size`              -> `quarantine.size` (2 sites)
  - `Array.from(quarantined)`       -> `quarantine.snapshot()` (6 sites)

Public worker-pool.ts API is unchanged — `getQuarantinedPaths()` still
returns the same defensive `string[]` copy. The behavioral contract is
preserved: paths are quarantined as opaque strings (the U9 / M5
non-normalization contract still holds — see the new dedicated test).

Tests:
  - 8 isolated unit tests for the quarantine module — pins the
    interface contract (empty start, add/has/size, dedup on repeated
    add, no separator normalization, snapshot defensive copy + freshness,
    size-getter live behavior).
  - All 86 existing worker-pool tests pass unchanged — they exercise
    the quarantine through the pool and act as the regression net for
    behavior preservation.

Why not the full 5-module extraction in this commit: doc-review A10's
concern is real — a single-consumer abstraction adds module-boundary
overhead (5 sets of imports, 5 dedicated test files, 5 interfaces to
keep in sync with worker-pool) without any structural benefit until a
second consumer materializes. Extracting one validates the pattern;
the remaining four can be moved on demand.

* feat(workers): wire protocol.ts encoded IPC into parse-worker + pool (U17)

Production worker IPC now uses the U16 binary wire format (1-byte tag +
4-byte LE length + UTF-8 JSON body) end-to-end. The pool encodes every
outgoing `sub-batch` / `flush` dispatch via `encodeMessage`; the worker
decodes incoming frames via `decodeMessage` and encodes its `ready`,
`starting-file`, `progress`, `sub-batch-done`, `result`, `warning`, and
`error` outputs the same way.

The load-bearing correctness fix is making `decodeMessage` accept
`Uint8Array` rather than only `Buffer`: Node's `worker_threads`
`postMessage` structured-clones the payload, which strips the `Buffer`
prototype on the receive side. A frame sent as `Buffer` arrives as a
plain `Uint8Array`, and `Buffer.isBuffer(raw)` returns false — so the
first attempt at U17 (gating decode on `Buffer.isBuffer`) silently
treated every incoming frame as POJO and the worker never responded.
The fix adopts the underlying memory zero-copy via
`Buffer.from(view.buffer, view.byteOffset, view.byteLength)` and uses
`raw instanceof Uint8Array` at every call site (parse-worker decode,
pool dispatch handler, pool ready-handshake handler, FakeWorker test
mocks, and the integration-test worker preamble).

The pool stays tolerant of POJO incoming so unit-test FakeWorkers
don't need rewriting — only the new outgoing encoded dispatches require
the test scaffolding to decode on receive, which the test FakeWorkers
and the integration test's inline `parentPort.on` wrapper now do.

The slot-drop integration test was rewritten from a shared-counter-file
race (which pre-U17 timing happened to land on the assertion-friendly
counter==2 endpoint, but post-U17 protocol decoding latency shifted to
counter==1 and produced 3 quarantines instead of 2) to a deterministic
path-based crash trigger: slot 0 crashes on a.ts, respawns, crashes on
the requeued b.ts, slot is dropped after budget exhausted; slot 1
handles [c.ts, d.ts] normally. Outcome no longer depends on inter-worker
file-write ordering.

Protocol coverage adds two regression tests pinning the Uint8Array
decode path: structured-clone-stripped frames decode identically to
their Buffer originals, and Uint8Array views with non-zero byteOffset
into a wider ArrayBuffer also decode correctly (catches `Buffer.from(uint8)`
copying semantics if a future refactor loses the zero-copy adoption).

All 94 worker-pool tests (9 files, unit + integration) pass; the full
unit suite (6128 tests across 268 files) passes unchanged.

* perf(workers): zero-copy file content transfer via transferList (U19)

Pool dispatch now hoists `{path, content: string}[]` file contents OUT
of the U17 JSON envelope into separately-allocated `Uint8Array`s whose
ArrayBuffers are passed to `worker.postMessage`'s `transferList` for
zero-copy ownership transfer. The envelope itself carries only
lightweight metadata (`{path, byteLength}` per file) and is structure-
cloned the same as before.

What this saves vs U17 baseline:

- **JSON.stringify of file contents on main thread** drops to zero —
  the envelope is now O(paths + sizes), not O(total bytes). For a 200-
  file sub-batch of 10 KB TS files, that's ~2 MB of escape processing
  per dispatch that disappears. JSON.stringify's per-character branch
  on quotes/backslashes/control chars is roughly 2x slower than
  UTF-8 transcode in TextEncoder, so the replacement is a CPU win
  even though it adds a single TextEncoder.encode per file.
- **Structured-clone memcpy of file contents** drops to zero — the
  contents' backing ArrayBuffers are ownership-transferred, not copied
  into the worker's heap. The envelope's struct-clone cost is now
  proportional to metadata size only.
- **JSON.parse on worker thread** likewise no longer scales with
  content size. Worker decodes each `Uint8Array` to string via
  `TextDecoder` lazily at the parse boundary — runs on the worker
  thread, parallel with continued main-thread work, vs U17's
  sequential JSON.parse blocking the worker before processBatch can
  start.

Pipelining: TextEncoder.encode (main) and TextDecoder.decode (worker)
can both run while the OTHER side is doing useful work. Under U17,
struct-clone was a synchronous main-thread blocker.

The ArrayBuffer ownership contract is load-bearing:

- File-content `Uint8Array`s are allocated via `TextEncoder.encode`,
  NOT `Buffer.from(str, 'utf8')`. TextEncoder produces a dedicated
  ArrayBuffer per call; `Buffer.from(str)` carves from Node's shared
  `Buffer.poolSize` slab for small strings, so transferring one
  pool-backed Buffer's ArrayBuffer would detach every other Buffer
  that shares that slab — silent data corruption.
- The envelope itself is NOT transferred. It MAY be pool-backed by
  `encodeMessage`, and at ~30-80 bytes/file the struct-clone cost is
  negligible. Not transferring avoids the same detach-collateral risk
  the contents path is careful to dodge.

Detection is strict: every input element must have both `path: string`
and `content: string`. A single non-conforming element disqualifies
the whole batch from the transfer path and falls back to the legacy
single-Uint8Array `encodeMessage` envelope. Safer than partial
transfer (which would split a sub-batch into mixed-shape messages
the worker can't reassemble).

`parse-worker.ts` `decodeIncomingMessage` recognizes the hybrid
`{envelope, contents}` shape, decodes the envelope, zips metadata
positionally with the contents array, decodes UTF-8 → string per file,
and hands the reassembled `ParseWorkerInput[]` to the existing
`processBatch`. Identical downstream behavior to U17 — the IPC
optimization is invisible above this line.

Test scaffolding (3 FakeWorkers + 1 integration-test preamble) gain a
`decodeDispatchedMessage` helper that tolerates BOTH shapes (legacy
single-frame Uint8Array AND the new hybrid envelope+contents) so the
in-process unit mocks keep their existing action-scripting API and the
9 ad-hoc integration test workers keep their `msg.type === 'sub-batch'`
handlers unchanged.

`buildDispatchMessage` is now exported from worker-pool.ts so its
contract can be tested in isolation. A new
`test/unit/worker-pool-transferlist.test.ts` pins:
  - hybrid shape produced for parse-worker inputs
  - transferList carries one ArrayBuffer per file in input order
  - envelope decodes to metadata only (no `content` field)
  - content bytes round-trip byte-for-byte through UTF-8 (ASCII,
    multi-byte, surrogate-pair emoji)
  - each content's ArrayBuffer is independently allocated (no pool
    sharing) — the load-bearing transfer-safety invariant
  - non-parse shapes, empty arrays, and mixed-conformance arrays all
    fall back to the legacy single-frame path

All 271 test files (6166 unit + integration tests) pass.

* fix(workers,tests,docs): apply ce-code-review findings (16 items)

Walks the full set of findings from a multi-agent code review (11
reviewers, 1 maintainability dispatch lost to tool-permission denial)
of the PR #1693 branch. All 16 actionable findings — 4 P1, 4 P2,
8 P3 — applied in a single pass against a consistent tree. Tests
pass (269/269 unit files, 29/29 integration).

P1 — bounds-only / disguised-bounds assertions across 4 test files
(per user-memory DoD §2.7):
  - worker-pool.test.ts: 5 sites — `nodes.length > 0` dropped (redundant
    after `.toContain('validateInput')`); `files.length >= 4` pinned to
    `.toBe(7)` (mini-repo/src has exactly 7 .ts files); `results.length
    > 0` pinned to `.toHaveLength(1)` (default sub-batch absorbs all 7);
    `result.fileCount >= 0` pinned to `.toBe(1)` (empty file is still
    "processed"); `warnRecords.length > 0` replaced with content-
    predicate `/respawn|dropping|replacement|did not report ready/`
    (catches silenced warnings); `fallbackExcludePaths.length > 0`
    pinned to exact `['one.ts', 'two.ts']` (deterministic given the
    single-slot pool + 2 items + per-item starting-file).
  - parse-impl-fallback.test.ts: 3 sites — `astCacheClearCalls >= 1`
    pinned to exact 4 (per-chunk × 2 + finally × 2); the two error-path
    delta checks pinned to exact +2 and +3 (verified empirically).
  - parse-impl-progress-monotonic.test.ts: `percents.length > 0` →
    `.not.toEqual([])`; per-element `Math.max(prev, cur)` tautology
    replaced with direct `if (cur < prev) throw`; final-percent
    `Math.min(last, 95)` tautology pinned to exact `.toBe(70)` (3-file
    skipWorkers fixture's deferred band lands at the band start).
  - parse-impl-large-fixture.test.ts: `Math.min(elapsedMs, BUDGET)`
    tautology removed; Promise.race rejection is the load-bearing
    wall-clock check.

P1 — terminate() lacks `.catch` mask:
  - worker-pool.ts terminate() now matches the `.catch(() => undefined)`
    pattern used at every other internal terminate site. Prevents a
    hung/OOM worker's terminate rejection from masking the original
    pipeline error when called from parse-impl.ts's finally block, and
    guarantees `workers.length = 0` / `activeSlots.clear()` always run.

P1 — hybrid envelope length-mismatch + null-payload silent data loss:
  - parse-worker.ts decodeIncomingMessage: explicit non-null-and-typed
    check before `.type` access (decodeMessage permits null payloads
    per encodeMessage contract); explicit length-equality assertion
    between `decoded.files` and `contents` before zipping. Without
    these, `TextDecoder.decode(undefined)` silently returns "" and
    produces empty-content graph nodes — a contract violation that
    used to be undetectable. Both throws route through the outer
    try/catch → worker `error` reply → pool's recoverAndResume.

P1 — unsafe casts at the IPC boundary:
  - buildDispatchMessage now uses a properly-typed `isParseWorkerItemArray`
    type guard. The narrowed branch accesses `item.path` and
    `item.content` as statically-typed strings — a future rename of
    `ParseWorkerInput.content` would fail to compile inside the branch
    instead of silently mismatching at runtime. The remaining
    decodeMessage payload casts are bounded by the F3/F6 runtime
    guards.

P2 — idle-timeout retry bypasses circuit breaker:
  - worker-pool.ts timeout-retry IIFE now increments
    `consecutiveFailuresPerSlot[workerIndex]` alongside `respawnCount`.
    A slot that consistently times out (vs crashes) now trips the
    per-slot breaker, instead of consuming its full respawn budget
    over potentially tens of minutes without the breaker firing.

P2 — null/non-object worker message crashes pool handler:
  - Dispatch handler in worker-pool.ts now guards `null /
    non-object / no string type discriminant` before `msg.type` access
    and routes through recoverAndResume on violation. Previously a
    legitimate `null` payload would throw TypeError out of the
    EventEmitter listener → uncaughtException on main, crashing the
    analyze.

P2 — workerPoolSize === 0 creates unusable pool:
  - parse-impl.ts now treats `workerPoolSize === 0` as `skipWorkers`
    at the gate. Matches the PipelineOptions docstring contract ("0
    disables the pool entirely — equivalent to skipWorkers"); avoids
    constructing a pool that rejects every dispatch and logs
    "Worker pool parsing stopped" per chunk.

P2 — encodeMessage 2-buffer allocation per frame:
  - protocol.ts encodeMessage coalesced to a single
    `Buffer.allocUnsafe + writeUInt8 + writeUInt32LE + buf.write
    (string, offset, 'utf8')`. Drops the intermediate
    `Buffer.from(JSON.stringify(...), 'utf8')` allocation + memcpy.
    Length pre-check via `Buffer.byteLength(string, 'utf8')` surfaces
    the uint32 cap before any allocation.

P3 — slotGenerations made optional on WorkerPoolStats so external
  implementations of getStats() that predate U12 don't compile-break;
  in-repo callers already use optional chaining.

P3 — buildDispatchMessage marked `@internal` so it isn't surfaced as
  public API by typedoc / api-extractor (it's a test-only export).

P3 — verboseThroughputLog hoisted above the chunk loop (env vars can't
  change mid-run; one O(env-read) per analyze, not per chunk).

P3 — corrected the messageerror routing comment in worker-pool.ts
  dispatch handler. `ProtocolDecodeError` is caught by the surrounding
  try/catch — distinct from `messageerror`, which fires for V8
  structured-clone failures before the message body would reach the
  handler.

P3 — initial pool spawn now uses a `Promise.allSettled` ready-handshake
  gate symmetric with `replaceWorker`. Dispatch awaits this gate before
  selecting slots, so an init-crashing initial worker is dropped from
  `activeSlots` and a downstream OOM/missing-native-binding failure
  surfaces in seconds (bounded by WORKER_READY_TIMEOUT_MS) rather than
  waiting for the first idle timeout (30s default).

P3 — `GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT`,
  `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS`,
  `GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD` added to:
    - CLI `--help` text in src/cli/index.ts
    - Root README env-var table
    - gitnexus/README troubleshooting section (new "Worker pool
      resilience tuning" subsection)

P3 — CLI `catch (e: any)` / `catch (err: any)` in analyze.ts replaced
  with `catch (err: unknown)` + narrowed access; matches modern TS
  best practice and the codebase pattern at other catch sites.

P3 — `WorkerPoolStats.terminated: boolean` field added (optional, for
  backward compatibility). `terminate()` sets it true; `getStats()`
  surfaces it. Distinguishes graceful shutdown from a circuit-breaker
  trip in observability surfaces.

* fix(parsing): sequential gap-fill for worker-quarantined chunk files (U20.U1)

When the worker pool's Layer 3 quarantine filters one or more files
out of a chunk's dispatch, the worker results returned to
processParsing are silently narrower than the input chunk. Without
this reparse, the graph for this run would be missing every quarantined
file's symbols/imports/calls/heritage with no failure signal.

After the existing per-chunk quarantine log emits in
processParsing's worker-path try-block, run processParsingSequential
on JUST the quarantined-in-chunk files. The sequential path writes
directly to the graph, so symbols for those files land alongside
worker output for the surviving files.

Mirrors the WorkerPoolDispatchError catch-block's processParsingSequential
call shape — same signature, same args, same scopeTreeCache wiring.
Emits a structured warn naming `reparsedPaths` so operators can
observe the sequential fall-through.

This fixes the in-run side of the corruption Codex's adversarial
review of PR #1693 flagged. The cross-run side (chunk-cache
poisoning) is closed by U20.U2 in a follow-up commit.

* fix(parse-impl): suppress chunk-cache write when any chunk file was quarantined (U20.U2)

The chunk hash at parse-impl.ts:424-428 is computed from every file
in the chunk. The worker pool's Layer 3 quarantine
(worker-pool.ts createQuarantine) filters quarantined files out of
dispatch, so `rawResults` reflects only the surviving files. Before
this commit, the write at line 500-507 stored that partial result
under the full-coverage chunk hash — and on the next analyze with
unchanged content, the cache HIT branch (line 439-464) silently
replayed the incomplete result. Symbols from the quarantined file
were missing from the graph for as long as the cache survived.

Codex's adversarial review of PR #1693 flagged this as a silent-
corruption class because there's no failure signal: no warn log
during the replay, no graph-equivalence check, no exit code change.
The corruption only surfaces if an operator notices a missing symbol
in `gitnexus_query` output.

Guard the write with `chunkFiles.some(f => quarantineSet.has(f.path))`.
When any chunk file is in the worker pool's cumulative quarantine
snapshot, skip the `parseCache.entries.set` call. Emits a verbose-
only info log so operators investigating "why aren't my chunks
caching" have a diagnostic trail.

Skipping the write means the next analyze gets a cache miss for this
chunk and re-dispatches it. Quarantine is session-scoped (a fresh
createWorkerPool starts with an empty quarantine), so the new pool
gives the quarantined file another chance. If quarantine fires again,
U20.U1's sequential gap-fill still produces a complete graph for that
run; the cache stays empty for the chunk until a fully-clean
dispatch lands.

The cache-hit replay branch at parse-impl.ts:439-464 is unchanged.
Its contract strengthens: "cache entries are complete" becomes true
post-fix, but the replay code doesn't need to know that.

Closes the cross-run side of the Codex finding. U20.U3 adds the
regression test.

* test(parse-impl): integration regression for quarantine + chunk-cache (U20.U3)

Pins the U20 fix end-to-end via REAL `worker_threads` + `createWorkerPool`.
Mirrors the writeReadyWorker pattern from `test/integration/worker-pool.test.ts`
— inline READY_PREAMBLE + custom test worker script that:

  1. Decodes the U17/U19 IPC protocol (Buffer frame OR hybrid envelope/
     contents shape) the same way the production parse-worker does.
  2. Emits a `{type:'ready'}` handshake so the pool's
     `waitForWorkerReady` resolves promptly.
  3. On a sub-batch containing `poison.ts`, emits starting-file +
     `process.exit(134)`. The pool attributes the death to `poison.ts`
     via the in-flight signal and adds it to the session-scoped
     quarantine.
  4. On a sub-batch without poison, synthesizes a minimal valid
     `ParseWorkerResult` with one `Function` node per file (no
     tree-sitter dep in the test worker — the synthesized nodes give
     `mergeChunkResults` deterministic content for the graph).

Assertions exercise both fix layers:

  - U1 (sequential gap-fill in processParsing): the graph contains a
    `Function` node named `poison` AFTER the run. The custom worker
    never emits anything for `poison.ts`, so the only path for that
    symbol to reach the graph is `processParsing`'s sequential
    reparse of the quarantined-in-chunk file using the real
    tree-sitter parser against the actual source.
  - U2 (cache-write suppression in runChunkedParseAndResolve):
    `parseCache.entries` does NOT contain the chunk hash after the
    run; `parseCache.usedKeys` DOES contain it (chunk processed,
    cache write specifically skipped).
  - Cross-run: a second pass over the same fixture with the same
    parseCache and a fresh worker pool re-dispatches the chunk
    (cache empty), the worker crashes again, sequential gap-fill
    runs again, and the cache stays empty. Pins the round-trip
    contract.

Adds `workerUrlForTest?: URL` to PipelineOptions — same `@internal`
test-only injection precedent as `workerThresholdsForTest` (already
in PipelineOptions for thresholds). When set, parse-impl uses the
provided URL instead of the src/ → dist/ resolution dance. Production
call sites never set this field; the only consumer today is this
integration test.

Why integration over unit:
  - The fix lives at the boundary between parsing-processor.ts and
    parse-impl.ts under a real WorkerPool. Unit-mocking the
    worker-pool module bypasses the structured-clone boundary, the
    dispatch lifecycle, and the actual quarantine flow — it verifies
    the test setup rather than the contract. The real worker thread
    executing through the U17/U19 IPC protocol IS the load-bearing
    surface.
  - User-explicit preference (saved as
    feedback_integration_over_vimock.md memory). For worker-pool /
    parse-impl / IPC-touching code: write integration tests under

* refactor(parsing): remove sequential-parser fallback (U20 design pivot)

The worker pool's resilience layers — respawn budget, circuit breaker,
quarantine, slot-attribution, cumulative timeout — are now the SOLE
contract for handling worker failures. Two sequential-reparse paths
are removed from processParsing:

1. **U20.U1 sequential gap-fill for quarantined chunk files** (just
   added in commit 7dd489e9, now reverted). The pre-emptive rescue
   would re-run processParsingSequential on the file that ALREADY
   killed a worker — which for the most common quarantine cause
   (tree-sitter native SIGSEGV on a pathological file) re-triggers
   the same native crash on the main thread, killing the entire
   analyze. The "rescue" turned silent missing-symbols into a louder
   analyze-wide crash. Drop the rescue; accept the per-run gap.

2. **Pre-existing WorkerPoolDispatchError catch-block sequential
   fallback** (in production since PR #1693's resilience layer
   landed). Same risk class — when the pool exhausts its respawn
   budget / trips the circuit breaker, the failing files are
   precisely the ones likely to crash a sequential parser too. The
   "graceful degradation" hid pool failures behind degraded-but-
   completing analyze runs, making operational issues harder to
   surface and diagnose. Drop the catch-block; WorkerPoolDispatchError
   propagates to the analyze entry point where the user sees a clear
   hard signal.

What stays:
- The `skipWorkers: true` / small-repo path that uses
  `processParsingSequential` as the EXPLICIT primary path (not a
  fallback). Caller-driven opt-out and tiny-repo perf optimization
  are different intents.
- U2's chunk-cache write suppression in parse-impl.ts (commit
  7c9c9556). When quarantine fires, the chunk stays uncached so the
  next analyze with a fresh pool retries the file cleanly. That's
  the cross-run correctness Codex's adversarial review actually
  asked for.
- The per-chunk quarantine warn log (parsing-processor.ts) — operators
  see which files were skipped, both immediately and across runs.

What changed:
- `processParsing` worker-path try-block: unwrapped. The
  `processParsingWithWorkers` call is now direct (no try/catch
  wrapping); errors propagate to the chunk-loop caller.
- `parsing-worker-fallback.test.ts` rewritten: the previous 5 tests
  asserted graceful sequential-fallback behavior. Replaced with 3
  tests pinning the new contract — raw Error propagates, WorkerPool-
  DispatchError propagates with fallbackExcludePaths intact, normal
  quarantine signal does NOT throw and surfaces via progress detail.
- `parse-impl-quarantine-cache-skip.test.ts` (U20 integration test)
  updated: poison.ts is NOT in the post-run graph; surviving files
  are; chunk-cache stays empty; second pass re-dispatches and leaves
  cache empty.
- Plan doc updated to mark R1 as dropped and explain the U20 pivot
  in the Summary.

User decision: explicit directive ("let's remove the sequential
fallback entirely we must rely on entirely that the parallel process
is resilient enough to work itself through the code base"). The pool's
resilience layers are designed for this — respawn budget, circuit
breaker, quarantine, slot-generation, cumulative-timeout cap — and
adding a layer below them was redundant insurance with real downside.

Tests: 269/269 unit files (6135 tests) green. 31/31 worker-pool +
parse-impl integration tests green. The 2 reported "errors" in the
integration run are the pre-existing intentional-process.exit unhandled-
exception leaks from test workers — unchanged by U20.

* fix(workers,tests,docs): address ce-ultrareview findings F1/F2/F3/F4

Multi-lane review run on the PR #1693 branch surfaced four addressable
items beyond the blocking three.

F1 (minor, CodeQL): unused `findMatch` helper in
test/unit/scope-resolution/typescript/typescript-captures-anchor.test.ts:28
removed. `countMatchesTsx` flagged by the same CodeQL pass is a false
positive — it's called at line 88 by the JSX-anchor regression tests
so the rewrite case actually fires under TSX, not just TS.

F2 (medium, docs): bench/parse-throughput.md retitled as
"(scaffold)" with an explicit "no measurement data has been collected
yet" note above the table. The self-contradictory "Regenerate this
file before merging any PR that touches the ingestion pipeline"
instruction is dropped — the file ships intentionally without
numbers; the load-bearing perf-regression protection lives in
test/integration/parse-impl-large-fixture.test.ts (U6, 30s
Promise.race wall-clock budget). The Latest measurement section now
preserves the ~6s sequential observation as a smoke reference, not as
a regression target.

F3 (low, API hygiene): `WorkerPoolDispatchError.fallbackExcludePaths`
renamed to `quarantinedPaths`. The "fallback" terminology was
load-bearing under the pre-U20 design when `processParsing`'s
sequential-fallback catch-block consumed it to filter the fallback
file list. After commit be1f65c removed that catch-block, no
production code reads the field — but it stays populated by the pool
because the snapshot is genuinely useful operator diagnostics when
the breaker trips. The rename clarifies the field's actual semantics
(here are the files the pool quarantined before it tripped) without
changing wire behavior. Definition + the lone surviving in-pool
comment reference + both test assertions updated.

F4 (low → real fix, reliability): timeout-retry IIFE in
worker-pool.ts now consults `consecutiveFailureThreshold` and trips
the circuit breaker when the per-slot consecutive-failure count
crosses it. Closes a gap left by ce-code-review's REL-02 patch — that
fix added the `consecutiveFailuresPerSlot[workerIndex]++` increment
in the timeout-retry path but did NOT add the corresponding
threshold-check + tripBreaker call. Result: chronic pure-timeout
deaths accumulated counts that never tripped the breaker until the
slot also hit `respawnCount > maxRespawnsPerSlot`. Now timeouts and
crashes are structurally treated the same way by the breaker, which
is what the REL-02 increment was meant to enable. Test coverage:
worker-pool-resilience.test.ts already exercises the breaker via the
shared handleWorkerDeath path; this new branch traces the same
trip semantics with a different entry point, so the breaker-tripped
state is observable via the same `getStats().poolBroken` and
`WorkerPoolDispatchError.quarantinedPaths` surface.

Out of scope here (caller actions or future PRs):
  - F5 (info): cumulative-quarantine cache check is safe in practice
    because chunks are alphabetically deterministic; no action.
  - F6 (low): exit-code-0 quarantine exemption — pre-existing P2
    residual, bounded by quarantine + respawn budget; deferred.
  - F7 (info): dispatch non-reentrancy contract documented but not
    enforced; no production caller violates it; deferred.
  - PR title `[WIP]` removal — happens on GitHub side.

Tests: 274/274 test files (6185 passing, 30 skipped). The single
"error" in the integration runner is the pre-existing intentional-
process.exit unhandled-exception leak from the deliberate startup-
crash test worker, unchanged by these fixes.

* fix(workers): swap protocol body from JSON to V8 serialize/deserialize

CI scope-parity tests on Ubuntu surfaced silent data loss in the
worker IPC: `Phase 'scopeResolution' failed: scope.typeBindings is not
iterable` (Python, Go) and `importerModule.typeBindings.has is not a
function` (Python). Plus three #1066 large-file regression tests
(Python / C# / TypeScript) failed because call relationships weren't
resolving from the worker output.

**Root cause:** U17 introduced `JSON.stringify`/`JSON.parse` as the
protocol body codec. JSON has no representation for `Map`, `Set`,
`Date`, `RegExp`, `BigInt`, `TypedArray`, `undefined` values, or
circular refs — `JSON.stringify(someMap)` returns `"{}"`. Production
scope-resolution code keys data structures on Maps throughout
(`ParsedFile.scopes[*].typeBindings: ReadonlyMap<string, TypeRef>`,
plus `bindings`, `bySourceScope`, `byTargetDef`, the finalize-algorithm
edge indexes, etc.). The JSON round-trip silently turned every Map
into an empty object, manifesting downstream as iteration / `.has`
calls failing on the decoded payload.

**Fix:** replace the JSON body with `node:v8`'s `serialize` /
`deserialize`. That's the same structured-clone algorithm Node's
`worker.postMessage` uses natively — bit-for-bit compatible with the
pre-U17 implicit-clone path. Full type fidelity for Map, Set, Date,
RegExp, BigInt, TypedArray, undefined values, and circular refs. No
external dependency.

A previous iteration of this fix attempted to bolt a Map/Set
replacer+reviver onto the JSON path. Rejected in favor of V8
serialization because:
  - the JSON tag-marker approach requires per-type registration
    (Map, Set; then Date, RegExp, BigInt would each need their own
    sentinels); V8 handles them all uniformly
  - keys to JSON-encode would still need handling for nested types
    (and the marker approach doesn't survive nested Maps-in-Maps
    cleanly without recursive replacer logic)
  - V8 is faster than JSON for object-heavy payloads anyway (binary
    format, no string escaping pass)
  - the user-explicit ask was "a much more generic solution that will
    work for everything" — V8 serialization IS the generic solution

Trade-offs documented in the module header:
  - body bytes are opaque (binary, not human-readable) — debugging
    requires `v8.deserialize` ad-hoc; protocol.test.ts exercises every
    supported MessageTag including the new type-fidelity cases as a
    regression net.
  - format is tied to the running Node major. Pool always spawns
    workers on the same Node instance the main thread runs, so this is
    moot in production. Would matter if frames ever persisted to disk
    (nothing does today).

Protocol test file rewritten:
  - drops the JSON-specific byte-layout assertions (e.g. `body must
    equal "null" string`) — replaced with V8-derived expected lengths
  - adds a "structured-clone type fidelity" describe block that pins
    Map, nested Map, Set, Date, RegExp, BigInt, TypedArray, undefined
    values, and circular-ref round-trips. These are the load-bearing
    regression tests preventing a future "optimize" PR from quietly
    swapping V8 back to JSON.
  - the bad-body decode-error test now uses arbitrary non-V8 bytes
    instead of `{not-json}` — same intent.

Integration test READY_PREAMBLEs (worker-pool.test.ts and
parse-impl-quarantine-cache-skip.test.ts) update their inline
decoders to use `v8.deserialize` matching the production codec.
Both files have a standalone CJS worker preamble that can't import
dist/protocol.js by relative path, so the V8 dependency is required
via `node:v8` directly.

Tests: 271/271 unit files (6163 tests + 30 skipped). 28/28
worker-pool integration. 3/3 parse-impl integration. 791/791
scope-parity tests (the four CI-failing files: python.test.ts,
go.test.ts, typescript.test.ts, csharp.test.ts) all green again.

* refactor(workers): drop protocol.ts; use native postMessage + transferList

The protocol.ts framing layer was redundant — Node's `worker.postMessage`
already runs V8 structured-clone internally, the same algorithm that
backed `v8.serialize`. Wrapping V8.serialize → Buffer →
postMessage(struct-clone-Buffer) was a double-walk: one full
structured-clone pass to produce the Buffer, then another pass when
postMessage cloned that Buffer across threads. This commit cuts the
wrapper layer; workers and pool exchange POJO directly via
`worker.postMessage(value, transferList)`, with file-content
`ArrayBuffer`s in `transferList` for zero-copy ownership transfer.

What changes:

- **Deleted** `src/core/ingestion/workers/protocol.ts` (~180 LOC) +
  `test/unit/workers/protocol.test.ts` (~250 LOC). The MessageTag
  enum / ProtocolDecodeError / encodeMessage / decodeMessage surface
  is gone. Tag-based routing is replaced by the `msg.type`
  discriminant that every receive site already checks. Protocol-decode
  errors map to Node's `messageerror` event (V8 deserialization
  failures during postMessage), which the pool already wires to
  `recoverAndResume`.
- **`worker-pool.ts`**: `decodeIncomingWorkerMessage` removed; handlers
  receive POJO directly. `buildDispatchMessage` now returns
  `{message: {type:'sub-batch', files: [{path, content: Uint8Array}]},
  transferList: ArrayBuffer[]}`. The Uint8Array-per-content allocation
  via `TextEncoder.encode` is preserved (it's the load-bearing
  transfer-safety contract that keeps content out of Node's shared
  `Buffer.poolSize` slab). Flush dispatch is now plain
  `worker.postMessage({type:'flush'})`.
- **`parse-worker.ts`**: `decodeIncomingMessage` removed. The message
  handler receives POJO directly; the only conversion is
  `Uint8Array → string` for sub-batch file contents at the
  `decodeSubBatchFiles` boundary, before handing to `processBatch`.
  Outgoing messages are emitted as POJO via plain
  `parentPort.postMessage({type:'starting-file', ...})` etc. The
  `sharedHybridDecoder` is now `sharedContentDecoder` (same intent,
  clearer name for the simpler shape).
- **Test scaffolding**: FakeWorkers in `worker-pool-resilience`,
  `worker-pool-windows-quarantine`, and `worker-pool-slot-generation`
  drop their `decodeMessage` import + `decodeDispatchedMessage` helper.
  The helpers stay (still convert `files[i].content` Uint8Array →
  string for test-action introspection) but no longer touch any
  protocol framing — just shape-check for sub-batch.
- **Integration READY_PREAMBLEs** (worker-pool.test.ts and
  parse-impl-quarantine-cache-skip.test.ts): drop the inline
  v8.deserialize + envelope-unzip logic; the preamble is now just
  the ready handshake + a `parentPort.on` wrapper that converts
  `files[i].content` Uint8Array → string for the ad-hoc test worker
  scripts.
- **`worker-pool-transferlist.test.ts`**: contract tests updated for
  the new buildDispatchMessage shape — no `envelope` field anymore;
  `message.files[i].content` is Uint8Array; transferList holds each
  content.buffer in input order. Pool-slab independence still pinned.

What stays the same:

- Zero-copy file-content transfer via transferList — every file's
  ArrayBuffer is ownership-transferred to the worker (no copy).
- Full structured-clone type fidelity — Map / Set / Date / RegExp /
  BigInt / TypedArray / undefined / circular refs all preserved by
  Node's native postMessage. The V8 fix from commit 06f6957e is
  inherent in this path; there's no JSON layer to lose them.
- TextEncoder-per-content allocation — keeps content buffers out of
  the shared `Buffer.poolSize` slab so transferring one cannot detach
  another.
- The pool's resilience layers (respawn, breaker, quarantine,
  starting-file attribution, cumulative timeout, ready handshake,
  slot-generation guard) — unchanged.
- U20 chunk-cache write suppression on quarantine — unchanged.

Net: ~430 LOC removed (protocol.ts + tests + inline decoders + helpers),
~120 LOC simplified in worker-pool.ts and parse-worker.ts. One less
serialization pass per message on the hot path.

Tests: 270/270 unit files (6133 + 30 skipped). 822/822 integration
tests including the four CI-failing scope-parity files (Python, Go,
TypeScript, C#) — the V8-fidelity contract holds via native
postMessage with no explicit serializer. The single "error" reported
in worker-pool.test.ts is the pre-existing intentional
process.exit unhandled-exception artifact from the deliberate
startup-crash test, unchanged by this commit.

* refactor(parse-worker): drop legacy single-message dispatch mode

The `parentPort.on('message', ...)` handler had an `Array.isArray(msg)`
branch left over from a pre-sub-batch dispatch shape — the pool used
to send the items array directly, before the worker pool added
sub-batching and the `{type:'sub-batch', files: ...}` envelope.

No production caller has dispatched that shape since the sub-batching
refactor landed; verified by grepping the repo for `postMessage([`
patterns (zero matches). The `ParseWorkerInput[]` arm in the
`WorkerIncomingMessage` discriminated union also blocked
exhaustiveness narrowing — flagged by the kieran-typescript code
review (RR-01) as "if a future unit removes the legacy array path,
this arm should be dropped." Dropping it now.

What changes:
  - Remove the `Array.isArray(msg)` branch from the message handler.
  - Drop `ParseWorkerInput[]` from the `WorkerIncomingMessage` union;
    it's now a clean `{type:'sub-batch'} | {type:'flush'}` discriminated
    union, so the dispatch switch is exhaustive over `msg.type`.

Tests: 71/71 worker-pool unit + integration tests green (resilience,
slot-generation, windows-quarantine, transferlist, parsing-worker-
fallback, worker-pool integration, parse-impl-quarantine-cache-skip).

fix(ingestion): surface skipped large-file paths by default (#1659) (#1661)
* fix(ingestion): surface skipped large-file paths by default (#1659)

The 512 KB skip threshold in filesystem-walker is necessary, but the
existing warning only said "Skipped N large files" with no paths unless
GITNEXUS_VERBOSE=1 was set. In a repo with one or two oversized first-
party source files (e.g. a 17K-line cron handler), every IMPORTS/CALLS
edge from that file silently disappeared and the surface looked like a
Python resolver bug. Issue #1659 was filed against the resolver for
exactly that reason, but the resolver was fine; the file was being
dropped before parse.

Changes:
  * Always print up to 5 skipped paths after the count line.
  * If more than 5 were skipped, append "...and N more" with a hint to
    set GITNEXUS_VERBOSE=1 for the full list.
  * When running at the default threshold, emit a one-line hint about
    GITNEXUS_MAX_FILE_SIZE=<KB> so operators know how to widen it.
  * Cover the new behavior with three additional tests in the existing
    filesystem-walker integration suite, plus a new describe block for
    the >5 preview-cap case.

Verified end-to-end on a 680-file Python repo that hit #1659: before
the patch, "Skipped 3 large files (>512KB, ...)" was the only signal
and impact upstream of a function called from cron.py returned 1 of 5
real callers; after the patch the cron file is listed by name with the
hint, and running with GITNEXUS_MAX_FILE_SIZE=1024 brings the missing
callers back (impactedCount 1 -> 9).

* fix(ingestion): address #1661 adversarial review follow-ups (F1/F2/F3)

Three non-blocking nits flagged by the adversarial review on #1661:

F1 (output stability) — skippedLargePaths was populated by concurrent
fs.stat callbacks in batches of 32, so push order within a batch was
completion-order rather than input-order. The default preview's "first
5" could vary across runs on the same repo. Fix: sort the array before
slicing. New test asserts the verbose output is in sorted order.

F2 (boundary coverage) — the preview-cap describe block created 8
large files, so the SKIPPED_PREVIEW_CAP = 5 comparison was never
exercised at the exact <= boundary. A future off-by-one (<= → <) would
not fail the suite. Fix: add two tests, one with exactly 5 files (all
listed, no truncation) and one with exactly 6 files (5 listed plus
"...and 1 more").

F3 (hint accuracy) — isDefault compared effective bytes, so an
operator who explicitly set GITNEXUS_MAX_FILE_SIZE=512 (the same KB as
the default) would still see the "Set GITNEXUS_MAX_FILE_SIZE=<KB>..."
hint. Fix: gate the hint on whether the env var is unset, not on the
resulting byte value. New test pins the explicit-default-value case.

All 34 filesystem-walker tests pass (was 30; +4 new). Prettier clean,
typecheck clean for the changed files.

storage (ce-code-review finding #2).

* test(scope-resolution): extend Step 2 perf contract to implicit-self, MRO, field paths

Adds three sibling tests under the Step 2 perf contract describe block, each
asserting defs.byId.values() does NOT execute when ownedMembersByOwner is wired:

- implicit-self receiver via typeBindings.self (no explicitReceiver branch)
- 2-level MRO chain (Child extends Parent, save resolves on Parent at depth 1)
- FieldRegistry read via Step 2 (property lookup, separate registry path)

Pins the perf invariant on every distinct entry into walkReceiverTypeBinding
so a regression bypassing the hook on any sub-path now fails CI immediately
(ce-code-review finding #8).

* test(resolve-references): cover arity-overload filtering via resolveReferenceSites

Pins the orchestration-layer wiring of providers.arityCompatibility:
hook returns [save(arity 1), save(arity 2)], referenceSite.arity = 1,
arityCompatibility verdicts 'compatible'/'incompatible' by parameterCount,
exactly one reference emitted with toDef = the arity-1 overload.

registries.test.ts already covered arity at the buildMethodRegistry level;
this adds the missing entry-point check that resolveReferenceSites threads
providers correctly through to lookupCore.Step5 (ce-code-review finding #10).

* test(resolve-references): add hook-on vs hook-off parity test

Runs resolveReferenceSites twice on the same fixture (Parent.save method
hit + Child.name field hit, Child extends Parent MRO chain) — once with
ownedMembersByOwner wired to a synthetic registry, once with the hook
absent so collectOwnedMembers takes the defs.byId fallback. Asserts:

- stats are identical (sitesProcessed / referencesEmitted / unresolved)
- referenceIndex.bySourceScope entries have equal length
- toDef sets are equal
- each per-site reference (including evidence and depth) is .toEqual

Locks the semantic-parity claim in code while both paths still exist.
Will be removed alongside the fallback in finding #1 (ce-code-review #3).

* test(typescript): probe Step 2 MRO walk against ambient (declare class) base

Adds typescript-ambient-base-class fixture with an export declare class
AmbientBase + Derived extends AmbientBase and a call site d.ambientMethod().
Integration assertions:

- Both classes are detected
- EXTENDS edge Derived → AmbientBase emitted
- CALLS edge to ambient.ts:ambientMethod resolved via MRO walk

Probes the ce-code-review #6 concern that ambient-only owners (whose
bodies are never parsed) might be silently skipped by Step 2 after the
owner-keyed lookup change. Result: the call resolves correctly — the
method signature inside the declare class body still flows through
reconcileOwnership into model.methods, so the hook returns the right
ancestor hits. Residual risk is empirically closed.

* feat(scope-resolution): route nested types via owner-keyed TypeRegistry

Closes the Step 2 contract footgun where 'hook returns [] = authoritative
miss' silently dropped any owned def whose NodeLabel was outside the
method/field if-chain in reconcileOwnership.

- TypeRegistry: add nestedByOwner Map + lookupAllByOwner(owner, simple)
  + registerByOwner(owner, simple, def). Mirrors MethodRegistry/
  FieldRegistry shape; cleared with the rest on cascade clear.
- reconcileOwnership: route class-like NodeLabels (Class/Interface/Enum/
  Struct/Union/Trait/TypeAlias/Typedef/Record/Delegate/Annotation/
  Template/Namespace) via types.registerByOwner. New nestedTypesRegistered
  stat. Idempotent skip via nodeId match.
- validateOwnershipParity: extend the I9 invariant check to nested types.
- lookupOwnedMembersByOwner: merge methods + fields + nested-type hits;
  short-circuit when any one source contributes the full result.

Unblocks future receiver-MRO registries that need to resolve 'Outer.Inner'
through the receiver's type-binding chain (ce-code-review finding #5a).

* refactor(scope-resolution): make ownedMembersByOwner required; delete byId fallback

Per ce-code-review finding #1, the optional-hook design encoded a silent
O(|defs|) perf cliff into the type system: any RegistryContext built
without the hook regressed Step 2 to scanning every def per probe with
no warning. Production wires the hook unconditionally; the fallback was
exercised only by tests.

- RegistryContext.ownedMembersByOwner: required, returns readonly
  SymbolDefinition[] (no | undefined). Implementations MUST return [] on
  authoritative miss.
- collectOwnedMembers in lookup-core.ts collapses to a one-line forward
  to the hook; the defs.byId.values() scan and simpleNameOf helper are
  deleted (simpleNameOf had no other consumers).
- ResolveReferencesInput.ownedMembersByOwner: required to match.
- Tests: drop three fallback-path tests (registries Const fallback,
  resolveReferenceSites no-hook fallback, resolveReferenceSites Const-
  undefined fallback) and the hook-vs-fallback parity test added by
  finding #3. makeCtx in registries.test.ts now defaults to a real
  owner-keyed scan over the test fixture defs so tests that don't care
  about the hook keep working.

* perf(free-call-fallback): cache global callables by simple name once per pass

pickUniqueGlobalCallable scanned scopes.defs.byId.values() on every
free-call fallback site. After PR #1656 fixed Step 2, this scan became
the dominant remaining O(|defs|) hot path on large repos (ce-code-review
finding #4).

- buildGlobalCallableIndex builds a Map<simpleName, SymbolDefinition[]>
  over scopes.defs once at the top of emitFreeCallFallback. Same filter
  the per-site scan applied: Function / Method / Constructor, keyed by
  the last .-segment of qualifiedName.
- pickUniqueGlobalCallable consumes the prebuilt index via O(1) Map.get
  instead of iterating every def. Per-site complexity drops from
  O(|defs|) to O(|defs with this simple name|).
- Cost: O(|defs|) once per pass instead of O(|defs| * |free-call sites|).

Subsequent narrowing (arity, conversion-rank) and the model-side fallback
(model.symbols.lookupCallableByName + model.methods.lookupMethodByName)
are unchanged.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* ci: trigger build

feat(cpp): standard-conversion-sequence ranking for overload resolution (#1606)
* feat(cpp): add standard-conversion-sequence ranking to overload resolution (#1578)

Introduce `ConversionRankFn` abstraction and `cppConversionRank` implementation
to disambiguate C++ overloaded calls by argument-to-parameter conversion cost.
Exact type match (rank 0) beats standard arithmetic conversion (rank 2), which
beats non-viable mismatch (Infinity). Thread the rank function through
`narrowOverloadCandidates`, `pickImplicitThisOverload`, `pickOverload`, and
`pickUniqueGlobalCallable` via the `ScopeResolver.conversionRankFn` contract.
Add `findAllCallableBindingsInScope` scope walker for collecting all overloads
at the first binding scope. Guard against false ambiguity suppression when
candidates span different files (local-shadows-import preservation).

* fix: address Claude review findings on conversion-rank PR

Finding 1 (HIGH): add tests that exercise the conversion ranker.
  - p('a') with p(int)/p(double): char→int promotion (rank 1) beats
    char→double conversion (rank 2), forcing step 4b in
    narrowOverloadCandidates. Exact-type filter misses both overloads.
  - h(42, 2.5) with h(int,int)/h(double,double): multi-arg tied total
    score forces the ranker, both candidates score 2 → suppressed.

Finding 2 (HIGH): unify multi-candidate suppression across all paths.
  - Non-ADL free-call: suppress when narrowed.length > 1 (same-file
    guard), mirroring ADL merged-candidate behavior.
  - ADL ordinary-only: same pattern.
  - pickOverload: return OVERLOAD_AMBIGUOUS when candidates.length > 1
    after normalized-ambiguity check.
  - Case 0.5 (this receiver): set ambiguous=true when narrowed > 1.

Finding 3+4 (MEDIUM): implement rank-1 integral promotions.
  - char→int and bool→int now return rank 1 (ISO C++ [conv.prom]).
  - Updated comment to remove misleading ISO table header; document
    only the post-normalization ranking that is actually implemented.
  - Updated ConversionRankFn JSDoc in overload-narrowing.ts.

218/218 C++ tests pass (registry-primary). Legacy: 186+32.

* fix: implement pairwise dominance comparison for overload ranking

Replace the summed per-slot conversion cost with ISO C++-aligned
pairwise dominance comparison ([over.ics.rank]). F1 is better than
F2 only when F1 is not worse for every argument and strictly better
for at least one. Non-dominated candidates are returned; if multiple
remain they are genuinely ambiguous.

This fixes false CALLS edges for asymmetric multi-arg overloads:
h('a', 2.5) against h(int,int) / h(double,double) — the old summed
cost picked h(double,double) (cost 2 < 3), but ISO C++ considers
the call ambiguous because h(int,int) is better at arg 0 via char
promotion. The pairwise check correctly finds neither dominates.

Add h('a', 2.5) test case asserting zero CALLS edges alongside
the existing h(42, 2.5) symmetric-tie test.

218/218 C++ tests pass (registry-primary). Legacy: 186+32.

* docs: update step 4b JSDoc to reflect pairwise dominance

* feat: ADL Gap 3 — non-function ordinary lookup suppresses ADL

ISO C++ [basic.lookup.unqual] §7: if ordinary unqualified lookup finds
a name that is not a function or function template, ADL is not performed.

- Add hasNonCallableBindingInScope walker in walkers.ts
- In free-call-fallback, check for non-callable binding before invoking
  ADL; when found, bypass resolveAdlCandidates entirely
- Add test fixture cpp-adl-non-function-blocks: variable `int record`
  shadows the function name, blocking ADL from finding audit::record

* fix: use nearest-scope semantics for ADL non-callable blocker check

Finding 1: `hasNonCallableBindingInScope` walked the entire scope chain,
which could incorrectly suppress ADL when an inner scope had a callable
and an outer scope had a non-callable for the same name. Per ISO C++
`[basic.lookup.unqual]` §7, ADL is blocked only when ordinary lookup
itself finds a non-function — if ordinary lookup stops at an inner scope
where only callables exist, ADL should still fire.

Replace the separate `hasNonCallableBindingInScope` + `findAllCallable
BindingsInScope` calls with a combined `findCallableBindingsAndAdlBlocker`
walker that stops at the first scope with ANY binding for the name and
returns both `{ callables, nonCallableFound }`. One pass, one stop.

Fixture: cpp-adl-inner-callable-outer-noncallable — inner scope has
callable `swap(int,int)`, outer scope has `int swap = 0`. ADL fires and
resolves to `data::swap(Pair&,Pair&)` via argTypes narrowing.

* fix: block-scope function declaration suppresses ADL

Finding 2: ISO C++ [basic.lookup.argdep] lists three ADL blockers:
1. class member declaration (handled by pickImplicitThisOverload)
2. block-scope function declaration NOT a using-declaration (NEW)
3. non-function/non-template declaration (handled by nonCallableFound)

Extend `findCallableBindingsAndAdlBlocker` to return `blockScopeDeclFound`
when a callable is found at a Function or Block scope — indicating a local
forward declaration that should suppress ADL per standard.

`free-call-fallback.ts` now checks both `nonCallableFound` and
`blockScopeDeclFound` to determine ADL suppression.

Fixture: cpp-adl-block-scope-decl-blocks — `void record(int);` declared
inside function body prevents ADL from discovering audit::record.

* fix(cpp): propagate unnamed-namespace members through #include in registry-primary resolver

Anonymous-namespace contents in a header (e.g. `namespace { void f(); }`)
are reachable by unqualified lookup in any TU that #includes the header
per ISO C++ [basic.namespace.anon]/1 (the unnamed namespace behaves as
if a `using namespace unique;` is inserted into the enclosing scope, with
per-TU `unique`). The registry-primary path was filtering these defs out
of `expandCppWildcardNames` via both the structural Namespace-owner check
and the `isFileLocal` mark, so `hidden_probe(d)` from a TU including the
header resolved to nothing while the legacy DAG returned the correct edge.

Track anonymous-`namespace_definition` source ranges at capture time,
resolve them to ScopeIds in `populateOwners` (parallels inline-namespace
handling), and exempt those scopes from the two wildcard-expansion filters
plus the `populateCppNonGloballyVisible` structural set. `markFileLocal`
is preserved so the global free-call fallback still blocks cross-TU leaks
for files that do NOT #include the declaring file (cpp-anon-ns-cross-file
guard still passes).

* Initial plan

* fix(cpp): workspace-wide dependent-base name resolution (cross-file support)

- Replace per-file `populateCppDependentBases(parsed)` with a workspace-wide
  `populateCppDependentBases(parsedFiles)` that builds a cross-file class index
- Use qualified-name prefix for namespace disambiguation when multiple classes
  share a simple name (e.g. `Box` in two namespaces)
- Move the call from `populateOwners` (per-file) to the new `populateWorkspaceOwners`
  hook so all files are processed before resolution runs
- Add `cpp-two-phase-dependent-base-ns` fixture: Base<T> in a namespace in a
  separate file from Derived<T>, plus a namespace-free function with the same
  name — exercises the path where the class-owned filter does not apply
- Add two integration tests for the new fixture"

feat(cpp): migrate C++ to scope-based resolution model (#938) (#1520)
* fix(cpp): complete scope-resolution parity

* fix(ci): resolve formatting, lint errors for PR #1520

- prettier: format arity-metadata.ts, captures.ts, index.ts
- eslint: rename unused HEADER_GLOB to _HEADER_GLOB
- eslint: replace unsafe parser.parse() with parseSourceSafe()
- eslint: suppress intentional console.warn/log in sync.ts
- eslint: remove unused _it import alias in cpp.test.ts

* fix(ci): complete formatting, lint, and typecheck fixes

- prettier: format call-processor.ts, imported-return-types.ts,
  include-extractor.test.ts, cpp-captures.test.ts, cpp-imports.test.ts
- eslint: suppress intentional console.warn in manifest-extractor.ts
- typecheck: restore 'thrift' in ContractType union (was accidentally
  removed) and add thrift case to exhaustive switch in manifest-extractor

* fix(ci): revert unintended group module changes that broke tests

Restore types.ts, config-parser.ts, matching.ts, sync.ts, and
manifest-extractor.ts to upstream/main versions. The original commit
accidentally removed fields (thrift, workspace_deps, exclude_links_paths,
exclude_links_param_only_paths) from DetectConfig/MatchingConfig/ContractType
which are still referenced by matching.test.ts, config-parser.test.ts,
sync.test.ts and other integration tests.

This PR's scope is C++ scope-resolution parity only — group module
type definitions and logic should remain unchanged.

* fix(codeql): address security and quality alerts

- arity-metadata.ts, interpret.ts: replace single-pass template strip
  regex (/<[^>]*>/g) with a while-loop to fully handle nested templates
  like Map<List<int>> — resolves 'Incomplete multi-character sanitization'
- cpp.test.ts: remove unused vitest 'it' import since the file defines
  its own 'it' via createResolverParityIt — resolves 'Assignment to constant'
- include-extractor.test.ts: use fs.mkdtempSync() instead of predictable
  os.tmpdir()+Date.now() paths — resolves 'Insecure temporary file'
- interpret.ts: remove redundant 'name !== undefined' check (already
  guaranteed by early return) — resolves 'Comparison between inconvertible types'

* review: address Claude review findings on PR #1520

- Findings 1-3 (BLOCKERS): restore include-extractor.ts and its test to
  the main baseline. Block-comment fallback regression, suffix-resolve
  false-positive suppression, and the four deleted regression tests
  (#3-#6) are now back. These changes were unrelated to C++ scope
  parity and should not have been in this PR.

- Finding 4 (MAJOR, partial): revert COMPOUND_RECEIVER_MAX_DEPTH 6 to
  4. No C++ test exercises depth > 4 (cpp-chain-call uses a 2-hop
  chain), so the bump risked silent regressions on other migrated
  languages without justification. The wildcard-origin propagation in
  imported-return-types.ts is retained — C++ #include and using
  namespace both emit wildcard-origin bindings (cpp/import-decomposer
  .ts:40,90), so wildcard propagation is causal to C++ parity.

- Finding 6: tighten write-access dedup test with exact per-field
  counts (nameWrites = 2, addrWrites = 1) instead of total-count + sub
  string containment, so a regression in one of the two name writes
  can no longer be masked.

- Finding 8: skipped. Box-drawing characters in cpp/query.ts comments
  match the established convention used in csharp/java/php query
  files.

Finding 5 (int/long normalization tie-breaker) left as documented
follow-up — proper fix requires resolver-level tie-breaker logic and
risks regressing other arity-matching tests.

* fix(cpp): stop #include from leaking class methods and namespace members (U1)

The C++ registry-primary resolver was emitting impossible CALLS edges
for ordinary headers: an including file's unqualified save() resolved
to User::save and unqualified foo() resolved to ns::foo. Two leak
paths converged on localDefs:

1. expandCppWildcardNames (file-local-linkage.ts) iterated the
   flattened localDefs and exported every simple tail, including
   class-owned methods and namespace-contained symbols. Replaced with
   a scope-aware filter: build nodeId -> owning Scope from
   Scope.ownedDefs and skip defs whose owning scope is Namespace or
   Class.

2. The shared global free-call fallback's pickUniqueGlobalCallable
   walks the workspace registry by simple name and would still hit
   class methods / namespace members even with wildcard expansion
   fixed. Plugged the gap via the existing isFileLocalDef hook —
   semantically 'logically invisible cross-file' — by tracking per-
   file non-globally-visible nodeIds (populateCppNonGloballyVisible,
   called from populateOwners) and adding an ownerId !== undefined
   fast-path for class-owned defs.

Side fix in shared finalize-algorithm.ts: when wildcard expansion
resolves to a real target but produces zero propagating names, the
edge was dropped, taking the file-level IMPORTS edge with it.
Preserve the original wildcard edge so #include dependencies survive
even when the header exposes no unqualified bindings.

Tests: cpp-include-no-class-leak, cpp-include-no-namespace-leak, and
cpp-anon-ns-same-file-visible fixtures. Negative tests mode-gated to
REGISTRY_PRIMARY_CPP=1 via the expected-failures registry — legacy
DAG has no scope-aware filtering on the global fallback; backporting
is out of scope. All 2104 resolver integration tests pass under
registry-primary mode.

* fix(cpp): suppress receiver-bound CALLS when integer-width overloads collide (U2)

C++ arity-metadata normalizes int, long, short, unsigned, size_t to
'int' so single-candidate flows like 'process(42L)' match a 'long'-
typed parameter via loose matching. But when both 'process(int)' and
'process(long)' coexist as method overloads, they both end up with
parameterTypes=['int'] in the registry, and pickOverload's narrowing
returns 2 candidates with no way to disambiguate. The previous code
picked candidates[0] arbitrarily, emitting a CALLS edge to the wrong
overload roughly half the time.

Fix:
- Add isOverloadAmbiguousAfterNormalization in overload-narrowing.ts
  that detects >1 candidate sharing identical parameterTypes sequences.
- Have pickOverload return a new OVERLOAD_AMBIGUOUS sentinel when this
  fires.
- In the receiver-bound-calls loop, when pickOverload signals ambiguity,
  suppress the edge AND add the site to handledSites so the late-stage
  emitReferencesViaLookup pass does not re-emit the pre-resolved
  reference. Without the handled-mark, the reference index still
  carries a toDef and emits the same wrong edge.

Graph schema has no ambiguous-target edge model, so emitting two
edges (one per candidate) would require a separate schema change.
Zero-edge is the only safe outcome.

Other languages: the ambiguity check is a precondition gate, not a
behavior change for normal narrowing. Languages whose normalizers do
not collapse distinct types into a single token (verified by grep
over *-arity-metadata.ts) will never produce >1 candidate with
identical parameterTypes from genuinely distinct declarations, so
the branch is effectively C++-only in practice.

Test: cpp-overload-int-long fixture asserts exactly .toBe(0) CALLS
edges. Count=1 = arbitrary pick (the bug); count>1 = unsupported
ambiguous-edge model. Mode-gated to REGISTRY_PRIMARY_CPP=1 — legacy
DAG has no OVERLOAD_AMBIGUOUS wiring; backporting is out of scope.

All 2105 resolver integration tests pass under registry-primary; all
139 cpp tests pass under both modes (3 negative tests skipped in
legacy as documented).

* test(cpp): add integration coverage for anonymous-namespace, using-namespace conflict, and std-shim leakage (U3+U4+U5)

Three new end-to-end fixtures exercise the resolver pipeline against
scenarios that previously had only unit-level coverage or no coverage
at all (Claude review Finding 7):

U3 — cpp-anon-ns-cross-file:
  helper.cpp declares 'namespace { void worker(); }' and calls it
  internally. caller.cpp declares a separate 'void worker()' and calls
  it. Asserts (a) the cross-file CALLS edge from caller's run() does
  not target helper.cpp's anonymous-namespace worker, and (b) the
  same-file edge from helper_entry() to its own worker still resolves
  (positive guard against a 'no edges at all' regression making the
  negative check vacuously pass). Includes a state-isolation guard
  that re-runs the same fixture and asserts identical results,
  proving clearFileLocalNames() is called by the pipeline entry.

U4 — cpp-using-namespace-conflict:
  Two headers each declaring 'namespace a { foo() }' and
  'namespace b { foo() }' respectively, plus a caller doing
  'using namespace a; using namespace b; foo()'. Asserts exactly
  zero CALLS edges. One edge = arbitrary pick (the bug); two edges
  would require an ambiguous-target edge model GitNexus does not
  have. Depends on U1 — without scope-aware filtering, both foo()s
  would already be in the importer's wildcard binding set as simple
  'foo', so the test would pass for the wrong reason.

U5 — cpp-using-namespace-std-smoke:
  Fixture-local 'namespace std { void cout_write(); void println(); }'
  shim rather than real <iostream> — captures the wildcard-leak
  shape deterministically without depending on system-header modeling
  stability (out of scope per plan). Asserts (a) the project-local
  call resolves correctly, (b) no leak to shim STL symbols, and (c)
  no CALLS/ACCESSES edges from the caller into std-shim.h at all.

Negative tests for U2/U4 mode-gated to REGISTRY_PRIMARY_CPP=1 via
the expected-failures registry; legacy DAG lacks the OVERLOAD_AMBIGUOUS
suppression and the namespace-aware filtering, so the leaks persist
there. All 2112 resolver integration tests pass under registry-primary;
all 146 cpp tests pass under both modes (4 negative tests skipped in
legacy as documented).

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(cpp): scope-aware isSuperReceiver classification (U1)

The C++ isSuperReceiver hook used a regex `/^[A-Z]\w*::/` that
misclassified any uppercase-qualified call as a super-receiver call.
Singleton::getInstance(), std::Foo::bar(), and PascalCase namespace
calls all entered the super branch, where the absence of an enclosing
class (or wrong MRO context) dropped the resolution entirely.

Fix:
- New optional ScopeResolver hook isSuperReceiverInContext(text,
  callerScope, scopes). Languages where super classification depends
  on caller context define it; receiver-bound-calls.ts prefers it
  when defined and falls back to the simple isSuperReceiver(text)
  otherwise. Other migrated languages (Python, Java, C#, PHP, Go,
  TypeScript) are unchanged.
- C++ implementation: parse the LHS of '::' from the receiver text,
  resolve via findClassBindingInScope, and return true only when
  the LHS is a class-like def in the caller's enclosing class's MRO.
  Returns false for namespace LHS, unresolved LHS, self-class LHS
  (qualified self-calls aren't super), and any non-'::' form.
- Extended the C++ tree-sitter query to capture the LHS of
  qualified_identifier as @reference.receiver so qualified static
  member calls (Singleton::getInstance()) reach the receiver-bound
  Case 2 (class-name receiver) path. Without the receiver capture,
  qualified calls had no explicit receiver and could not resolve
  through any receiver-bound branch.

Test: cpp-namespace-qualified-not-super fixture. Singleton::getInstance()
from a free function asserts exactly 1 CALLS edge through the
qualified-call path. Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2113 resolver integration tests pass; all 147 cpp tests pass under
both modes.

* fix(cpp): suppress receiver-bound CALLS when default-arg overloads collide (U4)

ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and
'void f(int, int = 0)' are declared on S. The previous resolver
returned the first viable candidate via pickOverload's fallback.

Extended isOverloadAmbiguousAfterNormalization to take an optional
argCount: when provided, the predicate compares only the first
argCount slots of each candidate's parameterTypes. Candidates whose
declared-prefix matches up to argCount are treated as ambiguous
because default arguments make all of them equally viable for the
call.

Without argCount, behavior is unchanged (the original int/long
normalization-collapse contract, full-length equality required).
pickOverload now passes site.arity so default-arg ambiguity fires.

Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has
f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges.
Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2114 resolver integration tests pass; all 148 cpp tests pass
under both modes.

* fix(cpp): two-phase template lookup suppresses dependent-base members (U3)

ISO C++ two-phase name lookup: inside a class template body, unqualified
calls MUST NOT bind to members of a dependent base class. Only this->name
or Base<T>::name forms make the lookup dependent. GCC and Clang both
reject the unqualified form with 'declaration of f must be available'.

Before this fix, GitNexus's global free-call fallback walked the
workspace registry by simple name and bound unqualified calls inside
template bodies to dependent-base members, producing CALLS edges the
compiler would reject.

Implementation:
- New languages/cpp/two-phase-lookup.ts module: per-pipeline state
  recording (className, dependentBaseName) pairs at capture time and
  resolving them to nodeId sets during populateOwners.
- captures.ts detectCppDependentBases walks the AST once finding every
  template_declaration containing a class/struct definition. For each,
  it collects template-parameter names (typename T, class T, non-type
  int N, template-template parameters) and walks each base in the
  base_class_clause checking whether any inner type_identifier matches
  a template parameter. Conservative bias: typename T::U, decltype,
  and template-template-parameter shapes also classified as dependent.
- Extended scope-resolution contract's isCallableVisibleFromCaller
  hook with optional callerScope and scopes fields. C++ implements
  the hook to consult isCppDependentBaseMember: when the candidate
  is a member of a dependent base of the caller's enclosing class,
  the hook returns false and pickUniqueGlobalCallable skips the
  candidate.
- clearFileLocalNames also clears the dependent-base state per
  pipeline run.

Fixtures:
- cpp-two-phase-dependent-base: Derived<T> deriving from Base<T>,
  unqualified f() and i inside Derived's body. Asserts zero CALLS
  edges and zero ACCESSES edges respectively.
- cpp-two-phase-this-qualified, cpp-two-phase-non-dependent-base,
  cpp-two-phase-namespace-free-call-inside-template: positive
  fixtures left as documented gaps (this-> and qualified-name
  resolution inside template bodies are pre-existing resolver
  weaknesses independent of U3). Tracked separately.

Negative test mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-
failures registry; legacy DAG has no two-phase lookup.

All 2116 resolver integration tests pass under registry-primary; all
150 cpp tests pass under both modes (5 negative tests skipped in legacy
as documented).

* fix(cpp): implement V1 ADL (Koenig lookup) for free-function calls (U2)

Plan 2026-05-13-001 U2. Adds argument-dependent lookup as a new
candidate-generating tier in `emitFreeCallFallback`: when ordinary
unqualified lookup is empty, ADL surfaces candidates from each
value-class-typed argument's enclosing namespace.

V1 boundary (locked by cpp-adl-pointer-arg-boundary fixture):
- only direct enclosing-namespace closure
- only directly-named class-type values (pointer / reference / template-
  spec args excluded; closure rules deferred to V2)
- ADL fires ONLY when ordinary lookup is empty (no union-and-resolve)

Parenthesized name `(f)(s)` suppresses ADL per ISO C++
[basic.lookup.argdep]/3.1. Multi-candidate ambiguity (e.g. `process(int)`
vs `process(long)` after C++ int-width normalization) returns the
ADL_AMBIGUOUS sentinel — caller suppresses entirely, mirroring the
OVERLOAD_AMBIGUOUS contract from plan 2026-05-12-002 U2.

Implementation:
- `cpp/adl.ts` — new module: per-pipeline argInfoBySite + noAdlSites Maps
  populated at capture time, classToNamespaceQualifiedName Map populated
  during populateOwners; `pickCppAdlCandidates` returns
  SymbolDefinition | ADL_AMBIGUOUS | undefined
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveAdlCandidates` hook
- `scope-resolution/passes/free-call-fallback.ts` — invokes ADL hook
  between `findCallableBindingInScope` and `pickUniqueGlobalCallable`;
  marks site handled on `'ambiguous'` so emit-references doesn't retry
- `cpp/captures.ts` — detects `parenthesized_expression` function wrap;
  per-arg classification (pointer/reference/value class) preserving the
  shape info the existing arity-narrowing normalizer strips
- `cpp/scope-resolver.ts` — registers hook, populates associated
  namespaces, clears state in loadResolutionConfig

Negative tests (parens, pointer-boundary, ambiguous) gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG has no V1/V2
ADL boundary or ADL_AMBIGUOUS suppression.

154/154 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
147 pass + 7 skipped under =0 (legacy parity baseline).

* fix(cpp): inline namespace transitive walking + qualified namespace resolution (U5)

Plan 2026-05-13-001 U5. Two ISO C++ inline-namespace semantics:

1. Unqualified-lookup transitive visibility: inline-namespace members
   reach the enclosing namespace's scope as if declared there. The
   `populateCppNonGloballyVisible` exemption keeps them globally visible
   so cross-file unqualified lookup finds them.

2. Qualified-receiver transitive visibility: `outer::foo()` resolves to
   `outer::v1::foo()` when `v1` is inline (and through arbitrarily-deep
   nesting like `outer::v1::experimental::foo`, matching libc++ `__1` /
   libstdc++ `__cxx11`).

The second behavior required a new resolver case in
`receiver-bound-calls.ts` (Case 1.5: language-specific qualified-receiver
member lookup) because C++ qualified-namespace member calls had no prior
resolution path — receiver-bound Case 1 only handled
`ParsedImport.kind === 'namespace'` (Python/JS-style) and Case 2 handles
class receivers, neither of which fired for `outer::foo()`. The new
hook `resolveQualifiedReceiverMember` is opt-in; languages without
C++-style qualified-name semantics omit it.

Implementation:
- `cpp/inline-namespaces.ts` — new module: per-pipeline
  `inlineNamespaceRangesByFile` + `inlineNamespaceScopeIds` Sets;
  `markCppInlineNamespaceRange` at capture time;
  `populateCppInlineNamespaceScopes` resolves ranges → scope IDs;
  `resolveCppQualifiedNamespaceMember` walks namespace scopes by simple
  name and descends transitively through inline children only.
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveQualifiedReceiverMember` hook to the contract.
- `scope-resolution/passes/receiver-bound-calls.ts` — Case 1.5 invokes
  the hook between Case 1 (namespace imports) and Case 2 (class-name
  receiver). Returns undefined for non-namespace receivers so Case 2
  still resolves class-qualified calls.
- `cpp/captures.ts` — detects `inline` keyword child on
  `namespace_definition`; records 1-based range to match Scope.range.
- `cpp/file-local-linkage.ts` — `populateCppNonGloballyVisible` exempts
  inline-namespace scopes so cross-file unqualified lookup keeps their
  members visible.
- `cpp/scope-resolver.ts` — wires `populateCppInlineNamespaceScopes`
  into populateOwners (BEFORE `populateCppNonGloballyVisible` so the
  exemption sees populated state); registers
  `resolveQualifiedReceiverMember` hook.

4 fixtures: `cpp-inline-namespace-unqualified`, `-versioned`,
`-nested` (two transitive inline hops, STL `__1` shape), and
`-adl-participation` (composes with U2 — ADL surfaces records declared
inside inline child namespaces). All 4 assert exactly 1 CALLS edge with
correct target file.

Versioned fixture gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp
— legacy DAG can't disambiguate two same-name foos without inline
awareness. Other 3 coincidentally resolve in legacy.

158/158 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
150 pass + 8 skipped under =0 (legacy parity baseline).

* test(cpp): Phase 5 cross-unit composition tests for U1/U2/U3/U5

Plan 2026-05-13-001 Phase 5. Locks in correct behavior at the
intersections between the previously-shipped scope-resolver units.

Enhancement to U1: `isSuperReceiverInContext` strips template-argument
lists (`Base<T>` → `Base`) and namespace prefixes (`outer::v1::Base` →
`Base`) before resolving the receiver in the caller's scope chain. This
makes the super-receiver classification work for template-class
heritage shapes like `Base<T>::method()` and `outer::v1::Base<T>::f()`.

Three fixtures + four tests:

- `cpp-phase5-u1-u3-qualified-base-call`:
  `template<class T> struct Derived : Base<T>` with
  `Base<T>::method()` inside a template body. Asserts NO mis-routing
  (count = 0) — documents the V1 gap that template-class inheritance
  isn't captured as EXTENDS by the legacy DAG, so MRO walks are empty
  and the super branch can't dispatch. The composition still works
  correctly: U1's template-arg-stripping classifies `Base<T>` as a
  super candidate, but the empty-MRO terminates without false edges.

- `cpp-phase5-u2-u3-adl-from-derived`:
  `Derived : Base<T>` where `Base::record` shadows `audit::record`.
  Unqualified `record(e)` inside the template body should resolve via
  ADL to `audit::record` (because U3 + the `isFileLocalDef` class-
  owned filter suppress `Base::record`). Asserts 1 edge to audit.h
  and 0 edges to base.h.

- `cpp-phase5-u3-u5-inline-base`:
  `template<class T> struct Derived : outer::v1::Base<T>` where `v1`
  is inline. Unqualified `f()` inside `Derived<T>::g()` should NOT
  bind to Base::f (dependent-base suppression even across inline
  namespace prefix). Asserts count = 0.

Phase 5 tests asserting no-false-positives are gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG over-
resolves without the template-arg-stripping qualified-receiver path
and without two-phase dependent-base suppression.

162/162 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
152 pass + 10 skipped under =0 (legacy parity baseline).

fix(markdown): handle CRLF line endings in section heading parser (#1469)
* fix(markdown): handle CRLF line endings in section heading parser

split('\n') on CRLF content leaves a trailing \r on each line, and the
heading regex /^(#{1,6})\s+(.+)$/ (anchored with $) fails to match
'## Heading\r' because $ matches before end-of-string, not before \r.
Result: Windows-authored markdown silently produces zero Section nodes.

Use split(/\r\n|\r|\n/) to normalize all line-ending conventions.

Pure additive — LF-only files produce identical output. CR-only (Mac OS
Classic) becomes tolerated as a side benefit at zero risk.

Adds integration test markdown-processor-crlf.test.ts covering LF
baseline, CRLF (the regression), CR-only, mixed, and startLine/endLine
correctness.

* test(markdown): strengthen CRLF integration tests + clarify split comment

- Assert section names, levels, line spans, and CONTAINS hierarchy (not only counts)
- Document trailing-newline effect on endLine via exact toEqual expectations
- Reword markdown-processor comment: \$ only at end-of-string vs .+ before \\r

fix: resolve TypeScript ESM .js extension imports to .ts source files (#1525)
* fix: resolve TypeScript ESM .js extension imports to .ts source files

TypeScript ESM requires imports to use .js extensions even when source
files are .ts (moduleResolution: node16/bundler). The import resolver
now strips JS-family extensions (.js/.jsx/.mjs/.cjs) and retries with
TS equivalents (.ts/.tsx/.mts/.cts) when the literal .js file does not
exist. This fallback only applies to TypeScript/JavaScript languages.

Also adds .mts/.cts to the EXTENSIONS list for completeness.

Fixes #1503

* fix: address review findings — normalization, edge-case tests, integration test

- Fix makeCtx to use production normalization (.replace backslash)
  instead of .toLowerCase() (Finding 3)
- Add tests for .mjs/.cjs with competing .ts/.mts siblings (Finding 1)
- Add tests for ./dir.js → dir/index.ts boundary (Finding 2)
- Add integration test verifying full pipeline CALLS edges for ESM

feat: migrate Java to scope-based registry resolution (RFC #909 Ring 3) (#1482)
* Initial plan

* feat: implement Java scope-based resolution (RFC #909 Ring 3)

Add scope-resolution pipeline for Java, following the C# pattern:

- query.ts: tree-sitter query for scopes, declarations, imports,
  type bindings, and references against tree-sitter-java grammar
- captures.ts: orchestrator synthesizing import decomposition,
  receiver bindings (this/super), arity metadata, and reference arity
- import-decomposer.ts: decompose import_declaration nodes into
  kind/source/name markers (named, wildcard, static, static-wildcard)
- interpret.ts: convert captures to ParsedImport/ParsedTypeBinding
- receiver-binding.ts: synthesize this/super type-bindings on instance
  methods with superclass support
- arity-metadata.ts: extract parameter count/types using javaMethodConfig
- arity.ts: Java arity compatibility check with varargs support
- merge-bindings.ts: Java shadowing precedence (local > import > wildcard)
- simple-hooks.ts: bindingScopeFor, importOwningScope, receiverBinding
- import-target.ts: package path to file path resolution
- scope-resolver.ts: ScopeResolver implementation registered in registry

Wire scope hooks into javaProvider (java.ts) and register
javaScopeResolver in SCOPE_RESOLVERS registry. Add createResolverParityIt
wrapper to java.test.ts for parity testing.

All 172 existing Java tests pass. Java is NOT added to
MIGRATED_LANGUAGES — the resolver sits idle until the migration flag
is flipped.

(arity rejection is registry-primary only). The fixture now exercises both
the success path (2-arg, 3-arg) and the undersupplied path (0-arg).

* fix(augment): add CONTAINS fallback when FTS indexes unavailable

When the MCP server holds the KuzuDB write lock, the augment CLI opens
the DB read-only. FTS indexes cannot be created in read-only mode, so
searchFTSFromLbug returns ftsAvailable=false and an empty results array.
The existing early-return path silently produced no enrichment.

Add a Cypher name CONTAINS fallback that fires only when ftsAvailable is
false and BM25 produced no symbol matches. This covers the read-only DB
case (concurrent MCP server) and the first-run case (indexes not yet
built). The fallback is wrapped in .catch(() => []) and cannot throw.

When FTS indexes exist, this branch is never reached — behaviour is
unchanged for users without a concurrent MCP server.

* fix(augment): guard against CONTAINS '' and add no-FTS test coverage

Blocker 1 — CONTAINS '' on whitespace-leading patterns:
pattern.split(/\s+/)[0] returns "" when the input has leading whitespace
(e.g. "   ".split(/\s+/) → ["", ""]). In Kuzu, CONTAINS '' matches every
node with a name property, injecting arbitrary graph nodes into LLM context.

Fix: trim() before split, then guard on !firstWord || firstWord.length < 2.
No behaviour change for normal non-empty patterns.

Blocker 2 — zero test coverage on the FTS-unavailable code path:
The new CONTAINS fallback block (engine.ts lines 146-166) was exercised by
no existing test — all existing tests run with FTS indexes built. A second
withTestLbugDB fixture is added with no ftsIndexes, forcing searchFTSFromLbug
to return ftsAvailable: false, and asserts:
1. augment('login', ...) returns non-empty enrichment (fallback works)
2. augment('   ', ...) returns '' (CONTAINS '' guard holds)
3. augment('nxyz_notfound', ...) returns '' (no matching nodes)
4. executeQuery throwing returns '' (.catch(() => []) path)

* fix(augment): extend CONTAINS '' guard to FTS happy path and consolidate

The same split(/\s+/)[0] bug existed at line 125 (BM25 symbol filter,
FTS-available path) — a leading-whitespace pattern produced CONTAINS ''
there too, matching every node in BM25-matched files.

Fix: hoist patternFirstWord computation with trim() and the length guard
to the top of augment(), before any DB interaction. Both CONTAINS sites
(BM25 symbol filter and CONTAINS fallback) now use the single pre-validated
value. No behaviour change for normal patterns; the guard fires once for
all callers instead of being duplicated.

Also tighten the whitespace test in the no-FTS suite from 3 spaces to
4 spaces so it unambiguously exercises the patternFirstWord guard rather
than straddling the outer pattern.length < 3 boundary.

* test(augment): negative-safety test for ftsAvailable=true gate

Asserts the CONTAINS fallback does NOT fire when FTS is available but
BM25 returns zero results. Pins the safety property promised by the PR
description: behavior is unchanged for users without the read-only-DB
condition.

If anyone later loosens the gate to `symbolMatches.length === 0` alone,
this test fails.

* fix: address 5 production readiness review findings

Finding 1: Enforce static functions as file-local via expandsWildcardTo hook
- Add static-linkage.ts tracking module with markStaticName/isStaticName/expandCWildcardNames
- Update captures.ts to detect storage_class_specifier static on functions
- Wire expandsWildcardTo in scope-resolver.ts

Finding 2: Expand test coverage to ≥30 cases (74 unit tests added)
- c-captures.test.ts: 55 tests (scopes, structs, unions, enums, functions, typedef, field, variable, macro, imports, references, type bindings, arity, static)
- c-imports.test.ts: 12 tests (decomposition, interpretation, target resolution, determinism, edge cases)
- c-arity.test.ts: 18 tests (declaration arity, call arity, compatibility)

Finding 3: Deterministic #include resolution on depth ties
- Add lexicographic tiebreak in import-target.ts when candidates tie on path depth

Finding 4: Revert unexplained package-lock.json change
- Restored to pre-PR state (node >=20.0.0)

Finding 5: Planning artifact commit acknowledged (squash on merge)

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix: address second review findings 1-4 — isFileLocalDef hook, singleton docs, fn-ptr typedef, static isolation test

Finding 1: Added `isFileLocalDef` hook to ScopeResolver contract + implementation
in free-call-fallback.ts to filter C static functions from global free-call
fallback. Threads caller filePath through pickUniqueGlobalCallable so static
defs in other files are excluded.

Finding 2: Documented single-invocation assumption on staticNames Map. Added
clearStaticNames() call in loadResolutionConfig to prevent cross-repo
contamination in server-mode scenarios.

Finding 3: Added tree-sitter query pattern for function pointer typedef aliases
(typedef void (*callback)(int, int)) in query.ts. Added unit test.

Finding 4: Added c-static-isolation integration fixture (a.c with static helper,
b.c with non-static helper, caller.c) and test asserting no CALLS edge from
caller to a.c's static helper.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix: skip static isolation integration test in legacy parity mode

The `caller.c calls b:helper via include, NOT a:static helper` test
requires scope-based wildcard import binding + isFileLocalDef filtering
which is only available in the registry-primary path. The legacy DAG
path does not resolve cross-file calls through #include → prototype
chains. Added to LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.

* fix: address 3 review findings — static leakage in Phase 2, build-dir skip list, same-directory preference

Finding 1: Apply isFileLocalDef filtering in Phase 2 of pickUniqueGlobalCallable
so cross-file static defs cannot leak through the SemanticModel fallback path.

Finding 2: Expand scanHeaderFiles skip list with dist, build, out, target,
_build, .next, cmake-build-* to avoid generated headers shadowing source ones.

Finding 3: Implement same-directory sibling preference in resolveCImportTarget,
matching C compiler #include "…" relative-lookup semantics. Sibling check now
runs before exact match and suffix fallback.

Tests: 11 new header-scan tests, 4 new import-target tests (96 total C tests).

* fix: normalize header-scan paths to forward slashes for Windows compatibility

On Windows, path.relative() produces backslash-separated paths (e.g. src\foo.h)

Normalize output with .replace(/\\/g, '/') matching the convention used
throughout the scope-resolution pipeline.

* fix: address 4 findings — K&R arity, function-pointer docs, prototype docs, _filePath rename

Finding 1: K&R empty parameter list `int foo()` now returns unknown arity `{}`
instead of `{parameterCount:0}`. Distinguishes from explicit `int foo(void)`.
3 unit tests cover K&R definition, prototype, and void comparison.

Finding 2: Added code comment documenting function-pointer-variable call
capture as known architectural trade-off (same as Go resolver).

Finding 3: Added code comment documenting prototype/definition duplication
as graph-quality concern (no false CALLS edges).

Finding 4: Renamed `_filePath` → `filePath` in captures.ts since it is
actively used in markStaticName().

feat: add IncludeExtractor for C++ cross-repo include tracking (group) (#1156)
* feat: add IncludeExtractor for C++ cross-repo include tracking (group)

* fix: address CodeQL warnings on include-extractor

- Remove unused HEADER_GLOB constant in include-extractor.ts
- Use fs.mkdtempSync for secure temp dir creation in tests
  (CodeQL: 'Insecure temporary file')

* fix(group): close missing ); in manifest-extractor include branch

The 'include' branch in ManifestExtractor.resolveSymbol was missing
the closing ); for the executor() call, causing a syntax error that
broke ESLint, Prettier, and the full test CI on all platforms.

Reported by Claude PR review on #1156.

* chore: drop test/global-setup.ts + test/vitest.d.ts

Upstream removed these in commit 3f0c74fe (ladybugdb 0.16.0 upgrade).
Commit 3f5d21c5 accidentally restored them during a rebase dance.

* style(group): reformat VALID_CONTRACT_TYPES array to satisfy prettier

Adding 'include' pushed the array over prettier's 100-char limit,
so prettier prefers multi-line. Apply the reformat to unbreak
ci-quality/format job.

* fix(include-extractor): address PR #1156 Claude review findings #3-#7

Claude Deep Review raised 7 findings on the IncludeExtractor. #1/#2
(BLOCKERs) were fixed earlier. This commit closes the remaining five.

#3 HIGH  case-sensitive FS -> provider contract-id collision
  Document the deliberate case-folding trade-off on normalizeIncludePath
  (matches C/C++ convention on Windows/macOS; collapses Foo.h & foo.h on
  Linux). Add a unit test pinning the behavior.

#4 HIGH  suffixResolve short-suffix match silently drops cross-repo include
  When a local file ends with the same basename as an external include
  (e.g. local internal/api.h vs. #include "ext/api.h"), suffixResolve
  returned a bogus local hit and suppressed the cross-repo consumer.
  Replace the suffixResolve lookup inside include-extractor with a
  strict isLocalInclude() that only accepts full-path hits via
  SuffixIndex.get / getInsensitive. Callers of suffixResolve elsewhere
  are unaffected. Add 3 unit tests covering the regression.

#5 MEDIUM regex fallback matched #include inside /* ... */
  Strip block comments before running the fallback regex scan.
  Add a unit test.

#6 MEDIUM meta.source was hard-coded to 'tree_sitter'
  Track the actual extraction path with an extractionSource local and
  write it into meta.source so downstream audits can distinguish
  tree-sitter parses from regex fallbacks. Add 2 unit tests.

#7 MEDIUM missing end-to-end coverage
  Add test/integration/group/include-extractor-sync.test.ts with 3
  cases exercising extractor -> syncGroup -> CrossLink (mocked
  contracts, mixed-case/backslash normalization, real temp repos).

Tests: 21 unit + 3 integration, all green.

* fix(lbug): robust Windows lock acquisition for CI integration tests

LadybugDB's `new Database()` raises `Could not set lock on file` from
local_file_system.cpp synchronously inside the constructor — before any
query is issued, so `withLbugDb`'s query-time retry never sees it. On
Windows CI this surfaces as flaky integration tests due to AV-scanner
holds, libuv handle-release lag, and stale `.wal` sidecars from aborted
prior runs.

This change closes the gap at *open time*:

- `openLbugConnection` now wraps `new lbug.Database()` in a bounded
  busy-retry (5x100ms back-off) inside `lbug-config.ts`. Errors that
  exhaust the budget are tagged via `LBUG_OPEN_RETRY_EXHAUSTED` so
  `withLbugDb`'s outer 3x retry skips re-retrying a freshly-exhausted
  path (eliminates the 3x5=15-attempt / ~6s tail latency).
- For recognized test fixtures only (immediate-parent dir matches a
  known prefix AND resolves under `os.tmpdir()`), one final stale-
  sidecar sweep removes `.wal`/`.lock` and retries once. Production
  paths never enter this branch.
- `safeClose` on Windows runs a bounded `fs.open` probe to absorb
  native handle-release lag; logs a warning if the probe exhausts so
  operators can spot AV interference.
- `isDbBusyError` is now defined in `lbug-config.ts` as the single
  source of truth, re-exported from `lbug-adapter.ts` for compatibility.
- New tests cover open-time retry (happy/retry/exhaust/non-busy/tag),
  stale-sidecar sweep (test-fixture-only, production-rejection,
  preserves-original-error), `isTestFixturePath` direct unit suite
  (accept/reject/traversal/nested/trailing-sep), and
  `waitForWindowsHandleRelease` (openable/ENOENT/no-leak).
- The two new test files are added to vitest's existing serialized
  `lbug-db` project (already `fileParallelism: false`).

Closes the chronic Windows CI flake on lbug-touching integration tests
while preserving the existing single-writable-Database-per-process
LadybugDB contract. No public API surface changed.

* refactor(lbug): drop isDbBusyError re-export, import from lbug-config directly

The re-export from lbug-adapter.ts was a transitional convenience — with
the matcher now living in lbug-config.ts, having two import paths for the
same symbol invites future drift. Updated the two real consumers
(lbug-lock-retry.test.ts, lbug-open-retry.test.ts) to import from
lbug-config directly, removed the re-export equality test (now vacuous),
and refreshed the explanatory comment so it no longer references a
re-export pattern that doesn't exist.

* fix(lbug): silence benign LadybugDB v0.16.1 schema-init lock warnings on Windows

doInitLbug logs "⚠️ Schema creation warning: ... Could not set lock on
file" on every CREATE NODE TABLE call after the first init on a given
dbPath, on Windows. The lock is internal to LadybugDB v0.16.1 and is
resolved before the table is created — same tolerance pattern as the
existing "already exists" filter. Genuine cross-process lock contention
still surfaces on the next operation through withLbugDb's retry, so
filtering at the schema-init catch only suppresses noise, not signal.

Also extend the safeClose Windows handle-release probe to cover the
.wal sidecar (the previous Database's WAL handle was the slowest to
release, surfacing as the schema-query lock contention) and switch the
probe back to 'r+' so it actually detects exclusive locks.

Test loop in lbug-close-handle-release.test.ts simplified to 10 plain
iterations now that the underlying noise is filtered upstream.

* chore(lbug): isDbBusyError review fixes

- Drop redundant `could not set lock` term — already subsumed by `lock`.
- Document the intentionally-broad matcher: graph-DB lock-shaped errors
  ("deadlock", "unlock failed", "lock contention", "could not open lock
  file") are all treated as transient. If a non-transient surfaces,
  tighten the matcher rather than raise the retry budget.
- Add positive test cases covering those lock-shaped strings so the
  intent is visible and a future tightening would deliberately break
  these.
- Fix the open-retry back-off comment: max sleep is 100+200+300+400 =
  1000ms (no sleep after the final attempt), not 1.5s.

* fix(group): address PR #1156 follow-up review findings

Addresses two blockers and two mediums from the deep review.

BLOCKER 1: Windows CI ENOTEMPTY in sync.test.ts
  After this PR added writeBridge() to syncGroup, the existing test
  "writes registry to groupDir when skipWrite is false" fails on
  windows-latest. LadybugDB's checkpoint thread briefly outlives
  closeBridgeDb, holding a Win32 lock on bridge.lbug; the test's
  fs.rmSync then fails with ENOTEMPTY. Switched the test cleanup to
  cleanupTempDir from test/helpers/test-db.ts which already tolerates
  EBUSY/EPERM/EACCES/ENOTEMPTY with bounded retries — same pattern
  used elsewhere for LadybugDB-touching tests.

BLOCKER 2: Graph provider absolute-path bug
  extractProvidersGraph queried File.filePath from the LadybugDB graph
  but never stripped the repo root, so provider contract IDs ended up
  as include::/abs/path/foo.h while consumers emitted include::foo.h.
  These never matched through runExactMatch — silently producing 0
  cross-links for any indexed C++ repo (the primary use case).
  Now passes repoPath into extractProvidersGraph and applies
  path.relative(); rows that resolve outside repoPath (stale absolute
  paths from another machine, system headers somehow indexed) are
  dropped instead of polluting the registry.

MEDIUM: `../` relative includes produce spurious noise
  `#include "../foo.h"` is almost always intra-repo, but the suffix
  index can never match a `..`-prefixed path so it became a consumer
  contract no provider could satisfy. Now skipped before matching;
  covers both forward-slash and backslash forms.

MEDIUM: writeBridge error in sync.ts propagates uncaught
  contracts.json is the canonical source of truth and was just written
  successfully when writeBridge runs. A bridge-only failure (disk full,
  schema error, permission denied) shouldn't mask the registry. Wrapped
  writeBridge in try/catch with a logger.warn surfacing the path and
  recovery instructions.

Tests added:
  - extractProvidersGraph repo-relative ID generation (stub Cypher
    executor returns absolute paths)
  - extractProvidersGraph drops rows whose path resolves outside repo
  - `../foo.h` forward-slash skip
  - `..\foo.h` backslash-form skip

Skipped findings:
  - canExtract() removal (#5, low): canExtract is part of the
    ContractExtractor interface; every other extractor implements the
    same `return true` shape. Removing it from IncludeExtractor would
    break the interface contract — keeping for consistency.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(group): close PR #1156 Codex adversarial findings

Two HIGH findings from the Codex adversarial review on
feat/group-include-extractor:

1. Default-on extraction silently changes existing groups (BLOCKER)
   DEFAULT_DETECT.includes was true, so any pre-existing group.yaml
   that omits the new field would gain a wave of include::* contracts
   on the next sync after upgrade. Flipped to false (opt-in). The
   integration test already declares includes: true explicitly so it
   survives unchanged; the unit extractor tests bypass parseGroupConfig
   entirely; the sync test uses extractorOverride. Only config-parser
   needed regression tests covering omitted/explicit/false variants.

2. IncludeExtractor scans outside the indexed file universe (BLOCKER)
   The extractor was running glob('**/*', { ignore: STANDARD_IGNORES })
   twice with a hand-rolled 9-pattern list, no .gitignore/.gitnexusignore
   honoring, and no max-file-size cap. That meant File:<path> contracts
   could appear for files ingestion would never index, producing
   cross-links group impact cannot fan out to (silent false-negatives).
   Refactored to a single discoverIndexableFiles() helper that mirrors
   walkRepositoryPaths exactly: createIgnoreFilter + getMaxFileSizeBytes,
   one discovery pass shared by provider and consumer paths. Dropped
   STANDARD_IGNORES and SOURCE_GLOB entirely.

   third_party and 3rdparty (the C/C++ vendored-deps conventions) were
   in the local ignore list but not in the canonical DEFAULT_IGNORE_LIST
   used by ingestion. Folded both into the canonical set rather than
   keep a parallel list — the whole point of the Codex finding is that
   two file-discovery implementations drift. Single source of truth.

Tests: 5 new regression tests for the discovery alignment (.gitignore,
.gitnexusignore, max-file-size on both provider and consumer paths)
plus 4 for the opt-in default. All 30 include-extractor tests + the
494-test group suite + ignore-service tests pass.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(review): apply autofix feedback

ce-code-review surfaced 6 safe_auto findings on commit a9936a9b:

- T1 (testing, P2): the sync.ts:174 gate was untested with includes:false.
  Added a sync-level test mirroring the existing thrift-off pattern at
  sync.test.ts:545, asserting zero include contracts when the gate is
  disabled in a real syncGroup call.

- T3 (testing, P3): third_party and 3rdparty entries in DEFAULT_IGNORE_LIST
  had no regression test. Added both to ignore-service.test.ts's
  dependency-directories it.each block.

- M1 (maintainability, P3): discoverIndexableFiles JSDoc lacked a
  fork-warning relative to walkRepositoryPaths. Added a MAINTENANCE
  note explaining why the duplication is tolerated and the contract
  the two implementations must keep.

- M2 (maintainability, P3): thrift-extractor still hand-rolls its
  ignore array with no signal that DEFAULT_IGNORE_LIST additions
  silently do not apply there. Added TODO(#1156-followup) comments
  above both call sites.

- M3 (maintainability, P3): SOURCE_EXTENSIONS duplicated the four
  HEADER_EXTENSIONS entries with no expressed subset relationship.
  Spread HEADER_EXTENSIONS into SOURCE_EXTENSIONS so future header-
  extension additions propagate.

- C1+T4 (correctness+testing, P3, cross-reviewer corroborated):
  discoverIndexableFiles swallowed all fs.stat errors silently,
  including EACCES/EMFILE/EIO. Narrowed the catch to ENOENT (the
  documented benign glob/stat race) and added a logger.warn for
  any other code so operators can spot permission/resource issues.

All 629 tests pass; typecheck + prettier clean.

* fix(group): use retryRename in writeContractRegistry to absorb Windows EPERM

`storage.ts:62` used raw `fsp.rename` for the contracts.json atomic swap.
On Windows, AV scanners and concurrent renames briefly hold the
destination handle between rename calls, surfacing as EPERM/EBUSY.
The `insecure-tempfile.test.ts > concurrent writes do not collide`
test was flaking with `EPERM: operation not permitted, rename` on
windows-latest CI.

`bridge-db.ts` already has a battle-tested `retryRename(src, dst, 3)`
helper used at six call sites for exactly this pattern. Reusing it
here keeps the Windows-rename policy single-source-of-truth across
the group package.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(group): drop macro-style #include from consumer contracts

Tree-sitter's `(_) @import.source` wildcard matches the identifier node
of `#include PLATFORM_HEADER`, so the cleaned value `PLATFORM_HEADER`
slipped past the system-header / `..` filters and was emitted as a
permanently orphaned consumer contract (no file is named after a macro
identifier, so no provider can ever match). Add a shape guard that
skips cleaned values lacking both a path separator and an extension
dot, plus regression tests for single and multi-macro files.

Also document `IncludeExtractor.canExtract()` as unused by sync.ts
(gated via `config.detect.includes` instead) and kept solely for
ContractExtractor interface uniformity.

  source of truth, re-exported from `lbug-adapter.ts` for compatibility.
- New tests cover open-time retry (happy/retry/exhaust/non-busy/tag),
  stale-sidecar sweep (test-fixture-only, production-rejection,
  preserves-original-error), `isTestFixturePath` direct unit suite
  (accept/reject/traversal/nested/trailing-sep), and
  `waitForWindowsHandleRelease` (openable/ENOENT/no-leak).
- The two new test files are added to vitest's existing serialized
  `lbug-db` project (already `fileParallelism: false`).

Closes the chronic Windows CI flake on lbug-touching integration tests
while preserving the existing single-writable-Database-per-process
LadybugDB contract. No public API surface changed.

* refactor(lbug): drop isDbBusyError re-export, import from lbug-config directly

The re-export from lbug-adapter.ts was a transitional convenience — with
the matcher now living in lbug-config.ts, having two import paths for the
same symbol invites future drift. Updated the two real consumers
(lbug-lock-retry.test.ts, lbug-open-retry.test.ts) to import from
lbug-config directly, removed the re-export equality test (now vacuous),
and refreshed the explanatory comment so it no longer references a
re-export pattern that doesn't exist.

* fix(lbug): silence benign LadybugDB v0.16.1 schema-init lock warnings on Windows

doInitLbug logs "⚠️ Schema creation warning: ... Could not set lock on
file" on every CREATE NODE TABLE call after the first init on a given
dbPath, on Windows. The lock is internal to LadybugDB v0.16.1 and is
resolved before the table is created — same tolerance pattern as the
existing "already exists" filter. Genuine cross-process lock contention
still surfaces on the next operation through withLbugDb's retry, so
filtering at the schema-init catch only suppresses noise, not signal.

Also extend the safeClose Windows handle-release probe to cover the
.wal sidecar (the previous Database's WAL handle was the slowest to
release, surfacing as the schema-query lock contention) and switch the
probe back to 'r+' so it actually detects exclusive locks.

Test loop in lbug-close-handle-release.test.ts simplified to 10 plain
iterations now that the underlying noise is filtered upstream.

* chore(lbug): isDbBusyError review fixes

- Drop redundant `could not set lock` term — already subsumed by `lock`.
- Document the intentionally-broad matcher: graph-DB lock-shaped errors
  ("deadlock", "unlock failed", "lock contention", "could not open lock
  file") are all treated as transient. If a non-transient surfaces,
  tighten the matcher rather than raise the retry budget.
- Add positive test cases covering those lock-shaped strings so the
  intent is visible and a future tightening would deliberately break
  these.
- Fix the open-retry back-off comment: max sleep is 100+200+300+400 =
  1000ms (no sleep after the final attempt), not 1.5s.

feat(core): adopt pino structured logger (#1336)
* feat(core): adopt pino structured logger + add no-console eslint forcing function

Adds `pino` as the project-wide structured logger via a thin wrapper at
`gitnexus/src/core/logger.ts` exposing `createLogger(name, opts?)` and a
default `logger` singleton. Migrates the only security-relevant `console.warn`
site (`bridge-db.ts` `openBridgeDbReadOnly` retry-exhaustion path) to
`bridgeLogger.debug({groupDir, err, attempts}, 'msg')`.

Pino's NDJSON output is structurally log-injection-resistant (one record per
newline, all string fields JSON-escaped) — replaces the hand-rolled
`sanitizeLogValue` pattern that PR #1329 added on the `fix/insecure-tempfile-core`
branch. PR #1329's sanitizer remains as fallback until CodeQL confirms #466
closes via pino on this branch.

Also adds an ESLint `no-console: warn` rule scoped to
`gitnexus/src/**/*.ts` (excluding `cli/`, `server/`, `test/`, `bin/`, and the
logger module itself) as the forcing function — new code can't regress.
Existing 134 sites in `core/`, `mcp/`, `config/`, `storage/` get a
`// eslint-disable-next-line no-console -- TODO(pino-migration)` marker in a
follow-up commit so lint stays clean and the remaining work is grep-able.

Operator behaviour preserved:
  - `GITNEXUS_DEBUG_BRIDGE` truthy → bridgeLogger logs at debug level
  - `GITNEXUS_DEBUG_BRIDGE` unset → bridgeLogger filters debug messages
  - Output is NDJSON in production / CI / vitest
  - pino-pretty engages only when stdout is a TTY AND CI/VITEST env unset

Tests: 11 new logger.test.ts cases (level methods, debugEnvVar gating,
destination capture, undefined Error.message safety, CR/LF/U+2028/ANSI
single-record invariant). Group test suite (388 tests) passes unchanged.

`--no-verify`: pre-commit hook fails on PR #1302's pre-existing TS regression
at `scope-resolution/pipeline/run.ts:160` on main; documented in commit
`348d0c91` and recurring across the security-fix series.

Refs: #466 (codeql js/log-injection), PR #1329 follow-up.

* chore(lint): baseline-suppress 134 existing console.* sites with TODO(pino-migration)

Mechanical pass: prepends `// eslint-disable-next-line no-console -- TODO(pino-migration)`
above each existing `console.*` call in `gitnexus/src/{config,core,mcp,storage}/`
that the new ESLint rule would otherwise flag. CLI/server are exempt at the
config level (legitimate stdout output).

Zero functional changes. Generated by an in-repo node script that consumes
`eslint --format json` output and prepends the marker line at each reported
location. Verification:
  npx eslint gitnexus/src/      → 0 no-console warnings
  grep -rn "TODO(pino-migration)" gitnexus/src/ | wc -l  → 134

The marker tags inventory the remaining migration surface so future sweep
PRs can grep their target list. When a follow-up PR migrates a site, the
marker comment is removed alongside the `console.*` → `logger.*` swap.

`--no-verify`: same as parent commit (PR #1302 pre-existing TS regression on main).

* refactor(core): complete pino migration — replace all 134 console.* sites + flip ESLint to error

Codebase-wide sweep of every `TODO(pino-migration)` site flagged in commit
3e8e7c2a. 49 source files migrated, 134 `console.*` calls converted to
`logger.*` using pino's structured-arg convention (object first, message
second). All `TODO(pino-migration)` markers removed. ESLint `no-console`
flipped from `warn` to `error` so future regressions fail CI.

Source-side changes (49 files):
- Mechanical pattern: `console.X(msg)` → `logger.X(msg)`,
  `console.X(msg, val)` → `logger.X({val}, msg)` (bare-id shorthand) or
  `logger.X({err: val}, msg)` for Error-shaped names.
- Hand-fixed special cases:
  * `import-processor.ts`: `console.group/groupEnd` block → single
    `logger.error({...}, 'tree-sitter query error')` with merged fields.
  * `extension-loader.ts`: `console.warn` as default callback →
    `(msg) => logger.warn(msg)` lambda binding.
  * `cursor-client.ts`: variadic `console.log(...args)` → `logger.info({args}, '[cursor-cli]')`.
- `console.log` → `logger.info` (preserves operator visibility at default level)

Logger module (`gitnexus/src/core/logger.ts`) updates:
- Default level `info` (matches pino default; preserves `console.log` visibility)
- Default destination is **stderr (fd 2)** — keeps stdout (fd 1) clean for
  CLI tool data output (#324). Pino's default is stdout, which would
  contaminate `gitnexus query`/`cypher`/`impact` JSON output.
- Pretty-print TTY check now reads `process.stderr.isTTY` (matches new sink).
- `_captureLogger()` test helper: Proxy-backed singleton lets tests redirect
  the shared logger to a `MemoryWritable` and assert on captured NDJSON
  records via `cap.records()` / `cap.text()`. Restored on teardown.

Test-side changes (10 files):
- `max-file-size.test.ts`, `filesystem-walker.test.ts`, `worker-pool.test.ts`,
  `calltool-dispatch.test.ts`, `grpc-extractor.test.ts`,
  `ignore-service.test.ts`, `index-repo-command.test.ts`,
  `sequential-language-availability.test.ts`, `sync.test.ts`,
  `rust-workspace-extractor.test.ts`: replace `vi.spyOn(console, 'X')`
  patterns and ad-hoc `console.warn = ...` reassignments with
  `_captureLogger()` + `cap.records()` assertions.
- `analyze-worker-timeout.test.ts`: kept original `vi.spyOn(console, 'error')`
  — exercises CLI code (cli/analyze.ts) which is exempt from the migration
  (legitimate stderr output is the contract).

ESLint config: removed the `warn` baseline; new rule block is `error`
scoped to `gitnexus/src/**/*.ts` with the existing cli/server exemption
preserved. Logger module + test/ + bin/ remain off.

Verification:
- `npm test` — 7762/7762 pass (excluding 29 pre-existing PR #1302 Go
  resolver failures unrelated to this change)
- `npx eslint gitnexus/src/` — 0 errors, 426 pre-existing warnings unchanged
- `npx tsc --noEmit` — only the pre-existing PR #1302 TS error
- `git grep -n "TODO(pino-migration)"` — 0 matches
- `git grep -n "console\." gitnexus/src/ | grep -v cli/ | grep -v server/ | grep -v logger.ts` — 2 comment references only

`--no-verify`: pre-commit hook fails on PR #1302's TS regression at
`scope-resolution/pipeline/run.ts:161` on main; same justification as the
parent commits in this PR series.

Refs: #466 (codeql js/log-injection), PR #1336.

* chore(tests): remove unused 'vi' import from worker pool and grpc extractor tests

* test: replace console.warn with logger capture in loadIgnoreRules error handling

* refactor(cli/server): tighten no-console — migrate diagnostic warn/error to pino

Tighten the cli/server ESLint exemption from `'no-console': 'off'` to
`'no-console': ['error', { allow: ['log'] }]`. `console.log` IS the contract
on stdout (CLI tool output for `gitnexus query | jq` consumers, server
pretty-printed banners) and remains permitted. Diagnostic logging
(`warn`/`error`/`debug`/`info`) goes through pino like the rest of the
codebase — same NDJSON-on-stderr routing, same structured-fields convention,
same log-injection-resistance.

Migrated 88 sites across 13 files (cli + server). Three sites in
`cli/analyze.ts` are intentional UI patterns (the progress-bar swaps
`console.warn`/`console.error` to `barLog` to prevent terminal corruption
during long-running indexing); these carry inline `// eslint-disable-next-line
no-console -- intentional console-routing for progress bar UX` comments
explaining why they bypass the rule.

Test wiring updated:
- `analyze-worker-timeout.test.ts`: switched back to `_captureLogger` (was
  reverted to console-spy in an earlier commit when cli/ was exempt).
  Imports `_captureLogger` dynamically inside each test so it sees the
  same module instance as analyze.js after `vi.resetModules()` rebuilds
  the singleton.
- `web-ui-serving.test.ts`: console-warn assertion swapped to
  `cap.records()` lookup of the new structured log shape (`r.err`).

Verification: full test suite passes (7791/7791 excluding 29 pre-existing
PR #1302 Go failures); 0 lint errors; 0 tsc errors (after the earlier
gitnexus-shared rebuild fix).

Refs: PR #1336.

* fix(logger): address PR review findings — pretty-stderr, log levels, structured fields

Three findings from the multi-agent review on PR #1336:

**[CRITICAL] pino-pretty was writing to stdout, breaking piped CLI output.**
`tryBuildPrettyTransport()` did not set the pino-pretty `destination`
option. pino-pretty defaults to fd 1 (stdout) even when pino's own
destination is fd 2 (stderr). With `shouldUsePretty()` true (interactive
shell, stderr-TTY) the formatted log lines landed on stdout — so
`gitnexus query "auth" | jq` saw query-timing log noise interleaved with
the JSON result and `jq` failed. Fix: pass `destination: 2` to the
pino-pretty transport options. The non-pretty path already used
`pino.destination({dest: 2})`; this aligns the two paths.

**[HIGH] `logQueryTiming()` and MCP startup banner used `logger.error()`
for non-error conditions.** Migration artifacts. Operator alerting rules
fire on every level≥40 record, so per-query timing telemetry at error
level would generate false positives on every successful query, and a
healthy MCP startup would page on-call.

  - `local-backend.ts:logQueryTiming` → `logger.debug` with structured
    `{ query, totalMs, phases }` fields. Operators wanting per-query
    timing set the appropriate log level.
  - `local-backend.ts:logQueryError` → kept at `error` (it IS an error)
    but restructured to `{ context, err: msg }` instead of template-literal
    interpolation.
  - `mcp.ts` "starting with N repos" banner → `logger.info` with
    `{ repoCount, repos }` structured fields.
  - `mcp.ts` "no repos yet" notice → `logger.warn` (operator-actionable
    but non-fatal; server still starts and serves).

**[MEDIUM] Hot-path worker-pool warns used template-literal
interpolation.** Two `logger.warn` sites in `core/ingestion/workers/
worker-pool.ts` (job-split timeout, single-item retry) embedded all
diagnostic context in the message string instead of pino's
mergingObject. Restructured to canonical
`logger.warn({ workerIndex, items, estimatedBytes, ... }, 'msg')` so log
aggregators can query fields independently. Existing tests pin on
`r.msg.includes('Splitting into ...')` / `'Retrying with ...'` — preserved
in the message string so test assertions still pass.

Verification:
- Logger tests 11/11 pass
- Worker-pool integration tests 21/21 pass
- Full suite 7791/7791 pass (excl. pre-existing PR #1302 Go failures)
- Lint 0 errors; tsc clean
- pino-pretty `destination: 2` confirmed via the pretty-build path

Refs: PR #1336 review.

* fix(logger): address ce-code-review findings — best-judgment auto-fix batch

Multi-agent review of PR #1336 (post-merge with main) found 17 actionable
findings. This commit applies the concrete fixes; remaining items are
documented as residual work below.

APPLIED (12 fixes across 13 files)

P1 — bugs introduced by the migration

- parse-worker.ts:1451 — restore the dropped `else`. The migration replaced
  `if (parentPort) ...; else console.warn(message)` with an unconditional
  `logger.warn(message)`, double-logging every warning when running in a
  worker thread.
- grpc-extractor.test.ts:585 — remove the spurious
  `import { _captureLogger } from '...';` line that was injected INSIDE
  the TypeScript template-literal string used as the `auth.client.ts`
  test fixture. It was being parsed as part of the fake source and
  could mask deduplication regressions.
- eval-server.ts (8 sites), mcp/core/embedder.ts (2 sites), local-backend.ts
  (1 site) — `logger.error` → `logger.info`/`logger.warn` for informational
  lifecycle banners (listening on, route listings, idle-timeout, model-load,
  vector-fallback). These were emitting at pino level 50 and tripping
  log-aggregator error alerts on every successful start.
- core/logger.ts — wire `GITNEXUS_LOG_LEVEL` env var into `buildBaseOptions`.
  The `logQueryTiming` comment told operators to set this var; previously
  it had zero effect because `buildBaseOptions` hardcoded `level: 'info'`.
- core/logger.ts — add a guard to `_captureLogger()` that throws when a
  prior capture is still active. Forgetting `restore()` between captures
  silently abandoned the previous MemoryWritable and corrupted logger
  state for the rest of the vitest worker.
- core/logger.ts — Proxy `get` trap now uses `Reflect.get(inner, prop, inner)`
  instead of `(inner as ...)[prop as string]`. The `prop as string` cast
  silently coerced symbol-keyed lookups (e.g. Symbol.toPrimitive) to the
  wrong key.
- embedding-pipeline.ts:259 — restore the `if (!vectorAvailable && isDev)`
  guard around `vectorUnavailableMessage`. The migration dropped both
  guards, emitting a warn on every production analyze run on non-VECTOR
  platforms.

P2 — error-shape fixes for pino's err serializer

- serve.ts (uncaughtException + unhandledRejection) — pass the Error
  itself in `{ err }` so pino's serializer captures type/message/stack.
  Was passing `err.message` (string) which lost the stack and shape.
- api.ts:1823 — same fix; was passing `err?.stack || err`.
- wiki.ts:587 — was passing the bare Error as the first arg to
  `logger.error(err)`, which pino coerces via `.toString()` and loses the
  shape; changed to `logger.error({ err }, 'wiki command failed')`.

P2 — design hygiene

- core/logger.ts — hoist `MemoryWritable` out of `_captureLogger` and
  export it; also export `PinoLogRecord` and `LoggerCapture`. Removes
  the duplicate definition in `logger.test.ts`.
- core/logger.ts — `_getInner()` now delegates to `createLogger()` for
  both branches instead of constructing pino directly when an active
  destination is set. Future `createLogger` defaults (serializers,
  redaction) now apply uniformly to test-capture mode.
- eslint.config.mjs — extract the three MCP stdout-write selectors into
  a shared `mcpStdoutWriteSelectors` const so the lbug-adapter
  file-specific override spreads them in instead of re-listing them
  verbatim. Stops a future selector addition from silently dropping
  protection in lbug-adapter.

P2 — test coverage

- worker-pool.test.ts ("rejects dispatch when replacement worker crashes")
  — added an assertion on `cap.records()` so the test actually verifies
  the warn-level emission, not just the rejection. Was capturing pino
  output and discarding it.
- logger.test.ts — added 4 new tests for `_captureLogger` lifecycle:
  basic capture, restore-stops-writes, double-capture-throws, and
  recapture-after-restore. The mechanism every converted test depends on
  was previously untested in its own module.

NOT APPLIED — residual actionable work (5 findings)

- #7 CLI human-readable error messages emit as JSON in non-TTY contexts
  (analyze.ts validators, EADDRINUSE banners, OOM/ERESOLVE recovery
  blocks). Design issue: needs a dedicated `cliMessage()` helper that
  bypasses pino. Scope is too large for this batch.
- #10 `tryBuildPrettyTransport()` unreachable catch / pino-pretty
  resolves lazily — the catch can never fire. Fix is to probe with
  `require.resolve('pino-pretty')` inside the try block. Mechanical but
  changes the safety contract; deferred for review.
- #11 inconsistent logger call shapes across the migration (bare strings
  vs `{ field }, 'msg'` vs multi-line banners). Advisory — no concrete
  mechanical fix; needs a stylistic convention pass.
- #12 `pino.destination({ dest: 2, sync: true })` blocks the event loop
  on every logger call from the main process. Fix needs `sync: false` +
  `flushSync()` hooks on `beforeExit`/`SIGTERM`. Non-trivial; deferred.
- #17 `pino.final()` not registered in serve.ts crash handlers — async
  pretty-print path may not flush before `process.exit(1)` on dev TTY.
  Defer; bounded to dev TTY scenarios.

Validation
- `tsc --noEmit` clean
- ESLint MCP-reachable scope: 0 errors, 219 pre-existing any/non-null warnings
- `vitest run test/unit`: 5204 passed, 10 skipped (4 new lifecycle tests)
- focused: logger.test.ts 26/26, worker-pool.test.ts 22/22, grpc-extractor 39/39

* fix(logger): harden runtime — pino-pretty packaging, sync writes, CLI UX

Implements the 5 logger-runtime findings from the multi-agent code review
and Codex's adversarial review (plan: docs/plans/2026-05-07-001-fix-pino-logger-runtime-hardening-plan.md).

U1 — pino-pretty to runtime dependencies (Codex P1, no-ship)
- Move pino-pretty from devDependencies to dependencies in
  gitnexus/package.json so production installs (npm i -g, npx) don't
  crash inside createLogger() the first time stderr is a TTY.
- Lockfile regenerated; npm ls --omit=dev confirms placement.

U2 — Real pino-pretty availability probe
- Replace tryBuildPrettyTransport()'s dead try/catch (wrapped a plain
  object literal that cannot throw) with a require.resolve('pino-pretty')
  probe via createRequire. Memoize via _prettyAvailable cache.
- On miss, emit a single stderr warning and fall back to defaultDestination
  (NDJSON on stderr). Belt-and-suspenders for --omit=optional and any
  other install variant where pino-pretty turns out to be missing.
- Export _tryBuildPrettyTransport + _resetPrettyAvailableCache for tests.
- Add 3 unit tests covering happy path, memoization, and warning bound.

U3 — Async destination + graceful-exit flush
- Switch defaultDestination() to pino.destination({ dest: 2, sync: false })
  so logger calls don't issue a blocking write(2) syscall on every record.
- Cache the destination in module-level _dest. Register process.on(
  'beforeExit', flushSync) once at module load (gated on !VITEST so
  vitest's between-test cleanup doesn't fight _captureLogger).
- Export flushLoggerSync() helper. Wire into existing shutdown handlers
  in cli/analyze.ts (SIGINT) and mcp/server.ts (SIGINT/SIGTERM/shutdown
  helper) so async-buffered records reach stderr before process.exit.
- Add smoke test for flushLoggerSync's no-op-on-empty-state contract.

U4 — Crash flush in serve.ts and api.ts
- Add flushLoggerSync() between logger.error and process.exit(1) in
  serve.ts uncaughtException/unhandledRejection handlers and api.ts
  uncaughtException handler.
- Pino v10 removed pino.final (the v10 transport architecture handles
  worker-thread flush on process exit automatically), so the simpler
  log + flush + exit pattern replaces the original plan's pino.final
  integration. Captured in the commented logger.ts JSDoc.
- api.ts shutdown() also flushes before process.exit(0).

U5 — CLI message helper + migrate top offenders
- New gitnexus/src/cli/cli-message.ts exporting cliInfo/cliWarn/cliError.
  Each writes plain text to process.stderr AND tees a structured pino
  record so users see human-readable banners while log aggregators get
  NDJSON. Auto-newlines, preserves embedded newlines, accepts structured
  fields.
- Add 6 unit tests covering tee shape, level mapping, newline handling,
  multi-line preservation, empty-message edge case.
- Migrate top user-facing offenders identified in review:
  - cli/analyze.ts: validators (--worker-timeout, --embeddings, --embedding-*,
    --embedding-device) + recovery blocks (RegistryNameCollisionError,
    OOM/heap, ERESOLVE, MODULE_NOT_FOUND). Multi-line recovery hints
    consolidated into single cliError calls instead of N consecutive
    logger.error('') lines that emitted N empty NDJSON records.
  - cli/serve.ts: EADDRINUSE banner + Failed-to-start error.
  - cli/eval-server.ts: listening banner with full endpoint list (split
    plain-text human banner from structured aggregator record so users
    don't see {"level":30,"endpoints":[...]} in their terminal).
- Update analyze-embeddings-limit.test.ts to spy on process.stderr.write
  instead of console.error (the validator now bypasses console).

Validation
- tsc --noEmit clean
- ESLint touched-file scope: 0 errors, pre-existing any/non-null warnings only
- vitest run test/unit: 5213 passed / 10 skipped (modulo a pre-existing
  parallel-worker flake in test/unit/group/insecure-tempfile.test.ts that
  doesn't reproduce when group/ is run in isolation — 456/456 there)
- focused: logger.test.ts 19/19, cli-message.test.ts 6/6,
  analyze-embeddings-limit.test.ts 9/9

* fix(cli): route hard-exit diagnostics through cliError to defeat buffer drain race

Codex's adversarial review on PR #1336 flagged that nine `logger.error/warn`
+ `process.exit(N)` sites in CLI subcommands could lose the diagnostic
because the pino destination is `sync: false` (plan 001 U3) and
`process.exit` skips the `beforeExit` flush hook. Symptom: a non-zero
exit with no visible message.

U1: migrate the nine sites to `cliError`/`cliWarn`
- gitnexus/src/cli/tool.ts (5 sites — query/context/impact/cypher usage
  errors + the no-index init failure)
- gitnexus/src/cli/remove.ts (3 sites — ambiguous-target, unsafe-storage-
  path, and rm-failed catches)
- gitnexus/src/cli/eval-server.ts (1 site — the no-index startup warn,
  using cliWarn to preserve the warn-level semantics)

`cliError`/`cliWarn` (gitnexus/src/cli/cli-message.ts, plan 001 U5) write
plain text directly to process.stderr AND tee a structured pino record.
The direct-stderr path bypasses the buffered destination entirely, so the
diagnostic survives any subsequent `process.exit` regardless of buffer
state. Removed the now-unused `import { logger }` from tool.ts (lint
caught it).

U2: regression test at gitnexus/test/integration/cli/tool-no-index-stderr.test.ts
- Spawns `node dist/cli/index.js query whatever` with empty
  GITNEXUS_HOME, asserts exit code 1 + stderr contains the no-index
  diagnostic. Pattern mirrors test/integration/mcp/server-startup.test.ts.

Honesty caveat: the regression signal is not deterministic. The
SonicBoom buffer happens to drain in time for short messages on a piped
stderr, so the test passes both pre- and post-fix in this environment.
The architectural fix is still correct — `cliError` removes the timing
dependency entirely, so future pino changes or platform-specific buffer
behavior can't reintroduce the race. The test locks the user-visible
contract (stderr must carry the diagnostic) even if it doesn't reproduce
the exact failure mode under controlled timing.

Validation:
- `tsc --noEmit` clean
- ESLint touched-file scope: 0 errors, 19 pre-existing any warnings
- `vitest run test/unit/cli-message.test.ts test/unit/logger.test.ts`:
  25/25 pass
- New regression test passes against built dist/

Closes Codex P1 from the post-runtime-hardening review.

* fix(ci): replace console.error with cliWarn in optional-grammars

CI lint failure on the merged tree: the repo-wide pino-migration rule
(no-console: ['error', { allow: ['log'] }] for cli/) forbids
console.error in CLI code. optional-grammars.ts was added by PR #1383
and used console.error for missing/broken-grammar warnings; that worked
under the MCP-narrow ESLint rule alone but breaks once the merged
broader rule applies.

Two sites migrated to cliWarn (operator-actionable warnings, not
errors): the broken-binding diagnostic (line 69) and the missing-grammar
diagnostic (line 99). Each now writes plain text to stderr AND tees a
structured logger.warn record with grammar/extensions/error fields.

Also: hoisted opts?.relevantExtensions into a local const so the closure
inside .some() narrows correctly without the no-non-null-assertion lint
warning at line 96.

Validation
- ESLint optional-grammars.ts: 0 errors, 0 warnings (was 2 errors + 1 warning)
- tsc --noEmit clean
- vitest run cli-message + logger: 25/25 pass

The log message reported ~/.config/opencode/skill/ (missing trailing s)
while the actual install path was already correct (skills/).  Fixes the
misleading output so users see the real destination directory.

* test(setup): add OpenCode plural skills-path integration test (#1381)

Verifies that setup installs skills into ~/.config/opencode/skills/
(plural) and that the singular path does not exist.

fix(mcp): close MCP server timeout — stdout discipline + cold-start friction (#1383)
* fix(lbug): route diagnostic logs to stderr to avoid MCP stdio corruption

Replace console.log/console.warn with console.error in core/lbug so
diagnostic messages reach stderr and never corrupt the JSON-RPC stream
on MCP stdio. Per spec, the server MUST NOT write anything to stdout
that is not a valid MCP message.

- lbug-adapter.ts:367 - schema creation warning (MCP-reachable via lazy
  DB init from tool handlers)
- lbug-adapter.ts:1047,1054 - legacy embedding fallback diagnostics
  (currently HTTP-only, but covered by upcoming no-console lint rule)
- extension-loader.ts:191 - default warn handler fallback used during
  DuckDB extension loading

* feat(mcp): add stdout sentinel via AsyncLocalStorage transport-write tagging

Untagged process.stdout.write calls now redirect to stderr with a
[mcp:stdout-redirect] prefix instead of corrupting the JSON-RPC frame
stream. Identification is correctness-by-construction: the transport
wraps every send() in withMcpWrite() (AsyncLocalStorage) and the
sentinel checks isMcpWrite() per call. A byte-shape heuristic would
have falsely rejected Content-Length frames (start with C, end with })
and misclassified multi-chunk writes.

- gitnexus/src/mcp/stdio-context.ts: AsyncLocalStorage helpers + factory
- gitnexus/src/mcp/server.ts: install sentinel in safeStdout Proxy,
  flush summary at process exit
- gitnexus/src/mcp/compatible-stdio-transport.ts: wrap send() write in
  withMcpWrite so transport frames pass through cleanly
- gitnexus/test/unit/mcp-stdout-sentinel.test.ts: 17 cases covering
  pass-through, redirect, prefix, truncation (default 200 / custom),
  rate limit (default 10), one-shot warning, summary, mixed sequences

* feat(eslint): forbid console.log/warn and process.stdout.write in MCP-reachable code

Add a narrow ESLint override for gitnexus/src/mcp/**, gitnexus/src/core/lbug/**,
gitnexus/src/core/embeddings/**, and gitnexus/src/cli/mcp.ts that:
  - sets no-console: ['error', { allow: ['error'] }] — only console.error
    survives, since stderr is the only spec-safe channel for diagnostics
    while the MCP stdio transport owns stdout for JSON-RPC frames
  - adds no-restricted-syntax matching MemberExpression and CallExpression
    forms of process.stdout.write to close the bypass path that the
    AsyncLocalStorage sentinel cannot guarantee

Migrates 18 pre-existing console.log/warn call sites in core/embeddings/
(embedder.ts, embedding-pipeline.ts) to console.error; these are reached
from gitnexus_query semantic search and would have polluted MCP stdio
once a query triggered the embedding pipeline.

Adds eslint-disable-next-line comments in pool-adapter.ts at the four
legitimate process.stdout.write sites — they ARE the captured-real-write
infrastructure used by the sentinel and the silenceStdout/restoreStdout
mechanism.

The override is forward-compatible with feat/pino-logger (PR #1336)
which adds a broader no-console rule for gitnexus/src/; the narrow rule
here is a strict subset and rebases trivially when #1336 lands.

* feat(setup): pin setup-generated MCP config to installed version, keep static configs on @latest

The user-facing MCP config that 'gitnexus setup' writes into editor configs
now references gitnexus@<installed-version> instead of gitnexus@latest, read
dynamically from gitnexus/package.json#version at module load. This skips
the npm-registry metadata roundtrip on every MCP connect and stays
reproducible until the user explicitly upgrades.

Static example configs and quickstart docs intentionally keep @latest:
  - .mcp.json, gitnexus-claude-plugin/.mcp.json
  - gitnexus-claude-plugin/skills/*/mcp.json (6 files)
  - README.md / gitnexus/README.md MCP examples
Pinning these would create per-release version-bump churn for marginal
(~100-500ms) savings. The dominant cold-cache cost is the native rebuild
addressed separately by the GITNEXUS_SKIP_OPTIONAL_GRAMMARS env var.

README adds a one-line steer above the @latest quickstart pointing
repeated users at 'gitnexus setup' for the absolute-path config that
bypasses npx entirely.

Tests refactored to assert against the dynamic version (createRequire of
package.json) so they don't break on every release bump:
  - gitnexus/test/unit/setup.test.ts
  - gitnexus/test/unit/setup-jsonc.test.ts
  - gitnexus/test/unit/setup-codex.test.ts
  - gitnexus/test/integration/setup-skills.test.ts (regex match)

* feat(install,mcp): GITNEXUS_SKIP_OPTIONAL_GRAMMARS opt-out + missing-grammar warnings

Postinstall scripts (build-tree-sitter-dart.cjs, build-tree-sitter-proto.cjs)
gain a strict 'process.env.GITNEXUS_SKIP_OPTIONAL_GRAMMARS === "1"'
early-exit so users without a C++ toolchain (or anyone wanting fast
'npm install gitnexus') can skip the native rebuild. Strict '=1' only —
'true', 'yes', '0' and any other value fall through to the rebuild.

Add gitnexus/src/cli/optional-grammars.ts: cheap require.resolve probe for
each optional grammar, with a stderr warning helper. The warning surfaces:
  - At MCP server start (cli/mcp.ts) — unconditional, since the server
    serves any indexed repo and we cannot pre-filter by language.
  - At 'gitnexus analyze' start (cli/analyze.ts) — conditional on the
    target repo containing .dart/.proto files (cheap glob), so users with
    no relevant code don't see noise.

README documents the env var with the strict '=1' value and the trade-off
(faster install, no Dart/Proto parsing until reinstalled).

* test(mcp): child-process integration test asserts end-to-end stdout discipline

Spawns 'node dist/cli/index.js mcp' as a child, drives the MCP stdio
handshake (initialize -> initialized -> tools/list), reassembles every
stdout chunk into Content-Length-framed JSON-RPC messages, and asserts
zero stray bytes. Any byte outside a valid header-then-body window is
captured and surfaced in the failure message alongside the server's
stderr — this is the regression gate for U1 (no console.log/warn in
MCP-reachable code) and U3 (AsyncLocalStorage stdout sentinel).

Time budget: 5s local / 15s CI for first frame; 10s/30s total. Asserts
the published GitNexus tool surface (list_repos, query, context, impact,
detect_changes, rename) is reported by tools/list.

Adds 'pretest:integration': 'node scripts/build.js' so 'npm run
test:integration' rebuilds dist before the spawn — closes the
'stale dist masks regression' DX gap.

* fix(mcp): address PR #1383 review — sentinel scope, grammar detection, lint, contract

Blockers:
- B2: detectMissingOptionalGrammars now actually require()s each grammar
  instead of require.resolve(). For 'file:' optional dependencies the
  package directory is always installed regardless of postinstall outcome,
  so resolve() never threw and the missing-grammar warning never fired
  for the exact target users (those who set GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1
  or whose native rebuild soft-failed). require() loads the entry, which
  triggers node-gyp-build and throws if .node is absent. Result memoized.

Should-fix:
- S1: Removed duplicate uncaughtException/unhandledRejection handlers from
  cli/mcp.ts. server.ts:startMCPServer already registers handlers with
  full stack traces; cli/mcp.ts handlers fired first with worse output and
  never got a chance to exit because server.ts shuts down immediately.
- S2: Sentinel is now actually global. New setActiveStdoutWrite() in
  pool-adapter so silenceStdout/restoreStdout cycles preserve a
  registered wrapper instead of unwinding to raw realStdoutWrite. At
  startMCPServer: install sentinel.write as process.stdout.write AND
  register it as the active handler. Direct process.stdout.write calls
  from anywhere (console.log, dependency banners, etc.) now route through
  the sentinel instead of bypassing it. The transport's _safeStdout Proxy
  remains as belt-and-suspenders.
- S3: ESLint no-restricted-syntax now also forbids destructuring of
  process.stdout (covers both 'const { write } = process.stdout' shapes
  and rest patterns).

Minor:
- M1: chunkToBuffer now handles plain Uint8Array (Buffer.from(u8)) instead
  of falling through to String(chunk) which produced '1,2,3,...' garbage.
- M2: Untagged-write callbacks are now invoked on next tick per the
  Node Writable.write contract — both within and beyond the rate-limit cap.
  extractCallback handles the (chunk, cb) and (chunk, encoding, cb) overloads.
- M3: setup.ts throws early if package.json#version is missing/non-string
  instead of emitting 'gitnexus@undefined'.
- M4: parser-loader.ts console.warn → console.error; ESLint scope extended
  to gitnexus/src/core/tree-sitter/** so future violations are caught.

New tests cover:
- Plain Uint8Array redirect (asserts no String(chunk) garbage).
- Writable callback fired async (next-tick) for both normal and
  past-rate-limit redirects.

Validation: cd gitnexus && npx tsc --noEmit clean; vitest run 7863 passed,
11 skipped; eslint clean on MCP-reachable scope; integration test green
against rebuilt dist/.

* fix(mcp): close pre-sentinel stdout window + tighten contracts

Address ce-code-review findings on PR #1383:

P1 — Sentinel install order (was: stdout corruption window during
mcpCommand pre-startup):
- Add idempotent installGlobalStdoutSentinel() to mcp/stdio-context.ts.
  It captures realStdoutWrite/realStderrWrite, replaces process.stdout.write,
  and registers with pool-adapter's setActiveStdoutWrite — exactly once.
- cli/mcp.ts now installs the sentinel as the FIRST line of mcpCommand,
  before warnMissingOptionalGrammars (which after the B2 fix actually
  require()s each native grammar binding and could emit node-gyp-build
  banners to raw stdout in the pre-sentinel window).
- mcp/server.ts startMCPServer keeps a safety-net call to the same helper;
  the second invocation is a no-op.

P1 — WriteFn type erasure:
- WriteFn now declared as  instead of
  , so the assignment
   and the
  setActiveStdoutWrite(sentinel.write) call don't silently cross a
  type boundary.

P1 — extractCallback fragility:
- Replaced backward-scan-with-undefined-break heuristic with a strict
  'last arg if function' check matching the documented Writable.write
  contract. No longer breaks on a future (chunk, options, cb) overload.

P2 — _detectionCache premature memoization:
- Removed the explicit cache. Node's module cache already memoizes
  require() — calling detectMissingOptionalGrammars multiple times is
  cheap. Removing the module-level mutable state makes the helper
  trivially testable (no need for a reset hatch).

P2 — Misleading 'reinstall' message on broken (not missing) grammars:
- detectMissingOptionalGrammars now distinguishes MODULE_NOT_FOUND /
  node-gyp-build 'no native build' patterns from other errors
  (SyntaxError, EACCES, native crash). Broken bindings get an
  actionable stderr line naming the real failure instead of the
  misleading 'reinstall to enable' hint.

Other:
- mcp/core/lbug-adapter.ts updated with a KEEP-THIS-FILE note. Tests
  use the path as a vi.mock seam (calltool-dispatch.test.ts and 7
  others); new non-test code may import core/lbug/pool-adapter.js
  directly. The maintainability finding flagging the shim as
  self-contradictory was incorrect — the shim has a real test purpose.

Validation: tsc clean, vitest 7863 passed (no regressions), eslint
clean on MCP-reachable scope, integration test green against rebuilt
dist/.

* fix(mcp): close import-time stdout corruption window

Codex's adversarial review on PR #1383 found that even though cli/mcp.ts
is loaded lazily by Commander, ITS static imports (startMCPServer,
LocalBackend, installGlobalStdoutSentinel, warnMissingOptionalGrammars)
evaluate synchronously when the module loads — well before mcpCommand's
function body runs. Three of those four imports transitively pulled in
core/lbug/pool-adapter.ts, which imports @ladybugdb/core at module top
level. The native binding's init can write to raw stdout in that
pre-sentinel window and corrupt the JSON-RPC frame stream.

Fix: shrink cli/mcp.ts's static-import closure to a single zero-dep
chain (mcp/stdio-context.js -> mcp/stdio-capture.js, both leaf-clean),
install the sentinel as the first executable statement of mcpCommand,
then dynamically import the heavy backend modules in parallel via
await Promise.all.

Per the plan at docs/plans/2026-05-06-002-fix-import-time-stdout-window-plan.md:

- U1: New leaf module gitnexus/src/mcp/stdio-capture.ts owns the
  stdout-capture singleton state (realStdoutWrite, realStderrWrite,
  activeStdoutWrite + setActiveStdoutWrite/getActiveStdoutWrite).
  Zero non-node: imports — adding any would re-introduce the hazard.

- U2: pool-adapter.ts re-exports the relocated symbols under the
  existing names so the test mock seam (8+ files use vi.mock on
  mcp/core/lbug-adapter.ts which re-exports * from pool-adapter)
  keeps working without churn. restoreStdout and the watchdog now
  read the active handler via getActiveStdoutWrite(). stdio-context.ts
  imports from stdio-capture directly.

- U3: cli/mcp.ts's static imports collapse to one
  (installGlobalStdoutSentinel). startMCPServer / LocalBackend /
  warnMissingOptionalGrammars become parallel await import()
  inside mcpCommand, after the sentinel install.

- U4: New regression test gitnexus/test/integration/mcp/import-closure.test.ts
  spawns a child Node process that imports dist/cli/mcp.js (without
  invoking mcpCommand), inspects the CJS module cache via createRequire,
  and asserts @ladybugdb/core (and tree-sitter native bindings) are
  NOT in the static-import closure. Characterization-first: this test
  was authored to fail against the pre-fix code and confirmed to do so
  before U1-U3 landed.

Validation: tsc clean; vitest 7865 passed / 11 skipped (2 new U4 cases);
eslint clean on MCP-reachable scope; integration server-startup test
green against rebuilt dist/.

* fix(mcp): drop dead ESLint selector + suppress redundant grammar warning

Two minor PR #1383 review findings:

1. eslint.config.mjs: removed Selector 3 (`Property[key.name='write'].properties:has(...)`).
   `.properties` is not a valid attribute on a Property node in the ESTree
   AST, so the :has clause never matched — dead code. Selector 4 covers
   the canonical `const { write } = process.stdout` shape; tightened its
   comment to make that explicit.

2. cli/mcp.ts: removed the unconditional warnMissingOptionalGrammars call
   at MCP startup. The analyze path already emits this warning at index
   time with relevantExtensions filtered to the repo's actual file types,
   and a repo can only be served by MCP after analyze has run. Repeating
   the warning unconditionally on every MCP session was pure noise on
   machines whose indexed repos don't use .dart/.proto.

* chore(mcp): address PR #1383 review nits

Three minor hygiene findings from the production-readiness review:

- cli/mcp.ts: rewrite stale comment that described
  warnMissingOptionalGrammars as living inside mcpCommand. The call was
  removed in ca617552 — this path no longer invokes it at all.
- test/integration/mcp/import-closure.test.ts: same comment drift fixed.
  Test assertion is unchanged and still passes for the right reason
  (cli/mcp.js's static-import closure is leaf-only).
- mcp/server.ts: rename _safeStdout to safeStdout. The leading underscore
  conventionally signals "intentionally unused" but the Proxy is passed
  to CompatibleStdioServerTransport on the next line.

No behavior change. Typecheck clean; ESLint MCP-reachable scope still 0
errors.

fix(test): widen worker pool retry timeout to prevent CI flake (#1323) (#1354) 2026-05-05 19:15:50 +01:00

fix(pool): wait for replacement worker online before dispatch (#1324)
* fix(test): widen worker pool retry timeout to prevent flake under load

The "replaces a timed-out worker" test used 150ms idle timeout (600ms
retry), which is too tight when CPU is contended during parallel test
runs. Increase to 500ms (2s retry) — the test exercises the retry
mechanism, not tight timing.

Closes #1323

* fix(pool): wait for replacement worker to come online before dispatching

Root cause: replaceWorker() spawned a new Worker but returned immediately
without waiting for the thread to start. The subsequent runWorker() call
started the idle timer and posted the sub-batch while the thread was still
booting. Under CPU contention, thread startup latency consumed most of
the retry timeout budget, causing the flake.

Wait for the 'online' event before assigning the replacement worker. This
ensures the idle timeout measures actual processing time, not thread
startup overhead. Reverts the test timeout widening (500ms→150ms) since
the root cause is now addressed.

No production performance regression was found — the 30s default timeout
is unaffected. Only the tight test timeouts were sensitive to startup
latency.

* fix(pool): harden replacement worker startup with three-event helper

Address review feedback on the waitForWorkerOnline implementation:

1. Add waitForWorkerOnline helper that listens for 'online', 'error',
   and 'exit' events with proper cleanup after settlement. Prevents
   the dispatch promise from hanging if a replacement worker crashes
   before coming online (e.g. OOM, native addon failure).

2. Wrap replaceWorker call site in try/catch that routes failures
   through fail() — prevents unhandled promise rejections in the
   async setTimeout callback.

3. Re-check stopped flag after awaiting replacement startup — prevents
   injecting a live worker into a pool that was stopped by a concurrent
   failure during the await window. Terminates the orphaned replacement.

4. Add integration test for replacement worker crash during startup:
   worker throws on second load (marker-file gated), verifying the
   pool rejects the dispatch instead of hanging.

* fix(pool): preserve original error in replacement worker catch

The bare catch{} discarded the original error from
waitForWorkerOnline, causing the startup-crash test regex to miss.
Bind the error and include its message in the re-thrown Error.

fix: prevent premature pool resolution in worker split-and-retry path (#1321)
* Initial plan

* fix: prevent premature pool resolution in worker split-and-retry path

Move `activeWorkers--` from before `await replaceWorker()` to after it.
This prevents `maybeDone()` from seeing `activeWorkers === 0` during the
async gap when another worker finishes and picks up the split jobs.

fix(typescript): name HOC-wrapped const declarations (forwardRef / memo / useCallback / useMemo / observer) (#1261)
Some checks are pending

Release Candidate / ci (push) Blocked by required conditions
Release Candidate / Publish release candidate to npm (push) Blocked by required conditions
Release Candidate / Build & Push RC Docker images (push) Blocked by required conditions
* fix(typescript): name HOC-wrapped const declarations (forwardRef / memo / useCallback / useMemo / observer / debounce)

Follow-up to issue #1166 / PR #1175. After fixing HOF callbacks (Promise
fan-out, queryFn pair-arrows, multi-action Zustand stores) and JSX-as-call,
the dominant residual 0%-capture pattern in real React UI codebases was
the HOC-wrapped variable declaration:

  const Button = React.forwardRef((props, ref) => { ... })
  const Card = memo((props) => { ... })
  const handleClick = useCallback(() => { ... }, [])
  const computed = useMemo(() => { ... }, [])
  const debouncedSearch = debounce((q) => { ... }, 250)

All share the AST shape `lexical_declaration > variable_declarator >
call_expression > arguments > arrow_function`. Pre-fix, neither the
registry-primary `query.ts` nor the legacy `tree-sitter-queries.ts` had
a `@declaration.function` pattern matching this shape, and the legacy
DAG's `tsExtractFunctionName` only walked `variable_declarator` and
`pair` parents — `arguments` parents fell through with `funcName = null`.

Result: every shadcn/Radix component, every memoised React component,
and every `useCallback` / `useMemo` callback bound to a const registered
as anonymous; calls inside attributed to the file. Sourcerer-fe audit:
~296 declarations affected (~57 forwardRef + ~21 memo + ~161 useCallback
+ ~57 useMemo).

Fix:
  - 4 new tree-sitter patterns in `languages/typescript/query.ts`
    (registry-primary), anchored on the inner arrow_function /
    function_expression — same anchor discipline as the existing
    `lexical_declaration` and `pair` patterns from PR #1175.
  - 8 mirrored patterns in `tree-sitter-queries.ts` (4 in
    TYPESCRIPT_QUERIES, 4 in JAVASCRIPT_QUERIES) for the legacy DAG
    and the CI parity gate.
  - New `arguments`-parent branch in `tsExtractFunctionName` that
    walks `arguments → call_expression → variable_declarator` and
    returns the const's name. Three guards keep it strictly scoped
    to HOC-wrapped declarations; bare statement-level HOC calls fall
    through anonymous.

Tests:
  - 11 integration tests + 9 minimal TS/TSX fixtures exercising
    forwardRef / memo / useCallback / useMemo / observer / debounce,
    with positive (named-Function + correct CALLS edge), negative
    (no phantom Functions for unbound HOCs, no phantom self-loops,
    no first-sibling-wins leakage), and cross-pollination assertions.
  - 8 new unit tests in `call-attribution-issue-1166.test.ts`
    pinning the legacy-DAG path: 6 attribution tests + 2
    @definition.function capture tests.

Trade-off documented inline: chained array-method declarations
(`const x = arr.find((y) => p(y))`) match the same shape and produce
a mostly-harmless phantom `Function:x` with one outgoing edge. The
false-positive cost is negligible vs. the React UI coverage gain.

Verification: - 11/11 typescript-hoc-wrapped (registry-primary)
  - 26/26 call-attribution-issue-1166 (8 new + 18 pre-existing)
  - 266/266 across all 4 typescript resolver test files (registry)
  - 236/236 typescript.test.ts on legacy DAG (CI parity gate)
  - 1693/1693 across all non-Kotlin/Swift resolver test files
  - tsc --noEmit clean; prettier clean; eslint clean (no new warnings)

* test(typescript): pin documented HOC trade-offs and close var-form parity gap

Addresses the four findings on PR #1261 (Claude bot review for #1261).
All findings flagged missing assertion tests for behaviour already documented
in code comments — none reported a real bug. The verdict was
"production-ready with minor follow-ups"; these tests strengthen the
documentation-to-test contract.

[medium #1] Array-method false-positive
  Pin `const found = items.find((item) => predicate(item))` →
  `predicate.attributedTo === 'found'` as an accepted FP. The const is a
  value, never invoked, so no incoming CALLS edge ever points at it; the
  outgoing edge is a minor mis-attribution we accept rather than maintain
  a HOC allowlist.

[medium #2] Nested HOCs (`memo(forwardRef(...))`) — no phantom Function:Wrapped
  Two integration tests in `typescript-hoc-wrapped.test.ts`:
    1. `Wrapped` is NOT a Function node (the outer call's first arg is a
       call_expression, not an arrow — no @declaration.function pattern
       matches the outer shape).
    2. The deepest arrow's `helper()` call is NOT attributed to
       Function:Wrapped (the deepest arrow is anonymous because
       call_expression.parent is `arguments`, not `variable_declarator`),
       and no Function-sourced CALLS originate from `nested.tsx`.

[medium #3] Multi-arrow argument dedup
  Pin `const x = call(() => first(), () => second())` — both arrows share
  the same `arguments → call_expression → variable_declarator` ancestor
  chain on the legacy DAG, so both attribute to "x". Documents the
  registry-primary dedup story alongside.

[low #4] `var X = HOC(...)` parity gap
  Registry-primary `query.ts` had `(variable_declaration ...)` HOC patterns
  but legacy `tree-sitter-queries.ts` (TS + JS) did not. Closes the gap by
  mirroring two `(variable_declaration ...)` HOC patterns into both legacy
  sections so the parity gate stays tight even if a codebase mixes
  `var X = HOC(...)` with `const X = HOC(...)`.

Validation
  - Targeted: 41/41 (28 unit + 13 integration) on registry-primary.
  - Broader TS suite: 60/60 across 4 resolver test files.
  - CI parity gate (`typescript.test.ts`): 236/236 on legacy DAG and 236/236
    on registry-primary.
  - Prettier clean. ESLint clean (5 pre-existing non-null-assertion
    warnings in the test file, unrelated). tsc --noEmit clean.
