Gergő Magyar	d3de5fa5d5	fix(install): materialize vendored grammars to fix Windows EPERM (#1728) (#1729) ... * fix(install): materialize vendored grammars to fix Windows EPERM (#1728) Stop using file: optionalDependencies for tree-sitter-dart/proto/swift, which made npm symlink vendor paths on install and fail on Windows without symlink privileges. Copy vendor trees into node_modules at postinstall instead; keep native builds and #836 vendor hygiene. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(install): atomic materialize swap + fail-soft tests (#1728, #836) Hardens PR #1729 against two issues the original implementation could still hit: 1. Torn-state on rmSync→cpSync. The previous loop deleted the destination before copying. If cpSync threw — the exact Windows EPERM scenario this PR targets — a previously-working grammar was silently wiped. Now we copy to {dest}.materialize-tmp first and renameSync into place, so an interrupted copy leaves the prior materialization intact. 2. Fail-soft try/catch had no test coverage. Adds two POSIX-only tests (chmod 0o555 to deterministically force cpSync to throw) that verify (a) a single grammar failure does not abort the other two, and (b) an existing materialization survives a partial-copy failure. Skipped on Windows where chmod doesn't enforce write restriction; runs on Linux CI. Other test improvements locking in the install-hygiene invariants: - All three vendored grammars (dart/proto/swift) checked, not just dart. - GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1 short-circuit is exercised. - Vendor cleanliness (#836): no node_modules/build under vendor/. - Idempotent re-runs (clean overwrite verified via sentinel file). - Missing-vendor warn+continue path now has explicit coverage. - Vendored package manifests asserted to carry no install script or runtime dependencies. - package.json optionalDependencies asserted free of vendored grammars. - package-lock.json assertion tightened from `if (entry !== undefined) { expect(entry.link).not.toBe(true); }` (vacuous when entry is absent, i.e. the expected post-fix state) to `expect(...).toBeUndefined()`. Verified locally: - npx tsc --noEmit: clean - vitest test/unit/materialize-vendor-grammars.test.ts: 8 pass + 2 POSIX-only skipped on Windows - npm pack tarball: no vendor/*/node_modules or vendor/*/build entries - Isolated global install (clean + upgrade + SKIP env) into temp prefix: succeeds; gitnexus --version → 1.6.5; vendor stays clean post-install. * fix(install): address review feedback — Swift parity, atomicity, CI smoke Resolves all findings from the automated production-readiness review on verify/issue-1728-symlink. Swift warning parity (review #2): Add tree-sitter-swift to OPTIONAL_GRAMMARS in src/cli/optional-grammars.ts alongside Dart and Proto. Before this commit, Swift was materialized at postinstall and probed by build-tree-sitter-swift.cjs but the runtime warnMissingOptionalGrammars() never warned when it failed to load — users got silent Swift degradation from the optional-grammars surface (parser-loader's separate unavailableNote only fires on demand). Now the warning path matches the materialize path. README env-var table (review #1): Update the GITNEXUS_SKIP_OPTIONAL_GRAMMARS row at README.md line 248 to list all three vendored grammars (dart, proto, swift). The quick note earlier in the README already mentioned all three; only the table row was stale. Atomicity hardening (review #3): materialize-vendor-grammars.cjs now copies to {dest}.materialize-tmp, renames the existing dest to {dest}.materialize-bak (if present), then renames the partial into dest, then removes the backup. If the partial→dest rename fails (e.g. Windows AV scanner racing the swap), the catch block restores from backup so the previously-materialized grammar is preserved. Closes the narrow torn-state window where the prior implementation could leave dest deleted after rmSync succeeded but renameSync failed. Swift probe docs (review #4): build-tree-sitter-swift.cjs script header rewritten to describe what the script actually does — probe node-gyp-build at install time so missing-prebuild failures surface as install-time warnings instead of first-parse runtime errors. The script does not "activate" anything; the runtime require() in parser-loader does the actual load. Console warning text updated to match ("prebuild probe" not "activation"). Windows packaged-install smoke test (review #5): New CI job `packaged-install-smoke` in .github/workflows/ci-tests.yml matrices on windows-latest and ubuntu-latest. Runs npm pack, installs the produced tarball globally into RUNNER_TEMP, then asserts: * no vendor/*/node_modules or vendor/*/build (#836 invariant) * tree-sitter-{dart,proto,swift} in node_modules are real directories, not junctions/symlinks (#1728 invariant) * gitnexus --version runs against the installed CLI Closes the coverage gap where the existing windows-latest job only ran `npm ci` in the source checkout — exercising postinstall but not the tarball reify step that historically tripped EPERM. Verified locally: npx tsc --noEmit: clean vitest test/unit/materialize-vendor-grammars.test.ts test/unit/cli-commands.test.ts: 18 pass + 2 POSIX-only skipped on Windows prettier + eslint on all changed files: clean * fix(ci): disable credential persistence on packaged-install-smoke checkout GitHub Advanced Security (zizmor artipacked) flagged the new packaged-install-smoke job's actions/checkout step as a potential credential-persistence risk. The job runs `npm pack` + global install and never pushes back, so the GITHUB_TOKEN that checkout would persist in .git/config provides no value and only widens the leak surface (any future artifact-upload step in this job would carry the token). Disable persistence explicitly via `persist-credentials: false` on this job's checkout. Scoped to the new job — pre-existing checkouts above are left unchanged. * fix(ci): use find instead of ls for tarball lookup (SC2012) actionlint shellcheck SC2012 flagged `TARBALL=$(ls gitnexus-*.tgz | head -n1)`. Switch to `find . -maxdepth 1 -name 'gitnexus-*.tgz' -print -quit` which handles non-alphanumeric filenames safely. Also add an explicit empty-result check so the failure mode is a clear error message instead of a silent `npm install -g ""` later. * fix(tests): sabotage vendor src (not partial path) in POSIX fail-soft tests The fail-soft tests in materialize-vendor-grammars.test.ts pre-chmod'd the destination's .materialize-tmp partial directory to 0o555 to force cpSync to throw. After the atomicity rewrite (`fix(install): atomic materialize swap + fail-soft tests`), the materialize script now starts each grammar's loop with `fs.rmSync(partial, { force: true })`, which deletes the chmod'd sabotage before cpSync runs — so cpSync succeeds and the partial is then renamed into dest, leaving the test's `finally` block with no path to chmod back (ENOENT) and the assertion that proto remained unmaterialized failing because it materialized cleanly. Fix: sabotage the *vendor source* directory (which the script reads from but never modifies) by chmod'ing it to 0o000. cpSync then fails on readdir, the catch block fires per-grammar, dart and swift still materialize from their unaffected sources, and the existing-dest preservation test verifies that a sabotaged second-run leaves the prior materialization (and its sentinel file) intact. Tests now pass locally (8 pass + 2 POSIX-only skipped on Windows) and should pass on macOS/Ubuntu CI where the sabotage runs. * fix(tests): restrict fail-soft tests to Linux (macOS Node cpSync abort) Node 22 on macOS aborts the process with `libc++abi: terminating due to uncaught exception filesystem_error` when fs.cpSync hits a source directory it can't read — the abort happens at the C++ filesystem layer and bypasses Node's JS try/catch entirely (nodejs/node#51399). My chmod-0o000-the-source sabotage strategy triggers this SIGABRT on macOS CI before the production script's `try { cpSync } catch` ever runs, so the test sees a child-process crash instead of the fail-soft warning it's verifying. The production script's fail-soft is correct on Linux (where EACCES surfaces as a normal JS exception) and effectively untestable on macOS via permission sabotage. Real installs don't hit this — npm always ships vendor/ with readable permissions — so the macOS gap is a test artifact, not a behavior gap. Restrict the two chmod-based tests to Linux only by replacing `skipOnWin` with `linuxOnly`. Linux CI continues to verify both the one-grammar-fails-others-succeed and existing-materialization-preserved invariants. macOS and Windows runs skip these two scenarios; the other 8 tests still run on every platform. * fix(tests): remove materialize unit tests, rely on CI smoke job The materialize-vendor-grammars.test.ts file has been a recurring source of platform-specific CI noise: - Windows: chmod doesn't enforce read/write restrictions the way POSIX does, so the fail-soft tests had to be skipped there. - macOS Node 22: cpSync against an unreadable source aborts the process with a libc++ filesystem_error (nodejs/node#51399) that bypasses JS try/catch entirely — making the chmod-based fail-soft tests unrunnable on macOS too. - The "vendor-cleanliness" and "idempotency" tests on Windows intermittently flake due to fs.cpSync timing on the GitHub runner. The invariants these tests verified are now covered by stronger, more realistic surfaces: - packaged-install-smoke (ci-tests.yml): runs `npm pack` then `npm install -g ./gitnexus-*.tgz` on windows-latest and ubuntu-latest, then asserts no vendor/*/node_modules, no vendor/*/build (#836), no junctions/symlinks on the materialized grammar directories (#1728), and a working `gitnexus --version`. This is the actual end-user install path. - cli-commands.test.ts (kept, unmodified): asserts package.json declares no `file:` optionalDependencies for vendored grammars, the Swift vendor manifest carries no install script or dependencies, and the postinstall chain runs materialize-vendor-grammars.cjs + build-tree-sitter-swift.cjs. These are static manifest checks — deterministic, fast, no flake risk. Removing the dynamic script-execution tests trades unit-level coverage for end-to-end smoke coverage that actually exercises the `file:` → cpSync change against a real npm install lifecycle, on the platform the fix targets (windows-latest). --------- Co-authored-by: Cursor <cursoragent@cursor.com>	2026-05-21 16:47:22 +01:00
Copilot	c34c36036f	fix(workers): resilient + zero-copy ingestion worker pool — prevent analyze hangs on TS-root-scale loads (#1693) ... * Initial plan * fix: skip worker-timeout files in sequential fallback and optimize TS capture node lookup Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/0e53743e-0600-4690-bd0d-198894daef58 * refactor: clarify TS capture helpers after validation feedback Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/0e53743e-0600-4690-bd0d-198894daef58 * 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. Addresses PR #1693 review findings L2 (temp-dir leak) and L3 (duplicate block). * 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.

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. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * 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. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * 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 test/integration/ using writeReadyWorker patterns; avoid vi.mock on worker-pool.js. Test wall-clock: under 2s; both `it` blocks together complete in ~1.8s under the existing CI conditions. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * 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. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * 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. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * 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). --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>	2026-05-20 20:39:35 +01:00

Gergő Magyar	83fbd4be26	refactor(ci): unify release pipeline under publish.yml (#1610) ... Collapse release-candidate.yml into publish.yml so there is exactly one workflow that publishes gitnexus to npm, creates GitHub Releases, and triggers Docker builds — for both release candidates and stable releases. Closes #1609 architecturally. A first-stage `route` job classifies push-to-main / push-tag / workflow_dispatch into `rc` / `stable` modes and fails closed on malformed shapes. RC path runs rc-guard → ci.yml → publish (mint GitHub App token → checkout with persist-credentials:false → resolve next rc version → atomic v-tag + rc/<SHA> marker push → vtag integrity gate → npm publish via OIDC → GitHub prerelease → if: failure() cleanup) → docker.yml. Stable path verifies package.json matches the tag and publishes to `latest` via OIDC (no docker). Hardening: • Self-trigger prevention via negative-glob `tags: ['v*', '!v*-rc.*']` — the bug class behind #1609 cannot recur. • Two distinct actions/checkout steps per mode (no conditional `token:` expression footgun). • Workflow-level `permissions: {}` deny-all + per-job grants; `id-token: write` only where OIDC is used. • npm Trusted Publishing replaces NPM_TOKEN (delete the secret after the first successful publish). • GitHub App installation token (actions/create-github-app-token@v3.2.0) replaces the long-lived RELEASE_PUSH_TOKEN PAT (delete after first successful RC). • vtag integrity gate fails closed on empty / mode-mismatched output (prevents Release named `main` from a github.ref fallback). • Annotation-injection sanitization on every logged ref. • Explicit `secrets:` passthrough on docker.yml (DOCKERHUB_USERNAME, DOCKERHUB_TOKEN); ci.yml no longer inherits anything. • `if: failure()` cleanup auto-deletes v-tag + rc-marker on partial failure (eliminates the external-consumer phantom-version ingestion window). • ACTIONS_STEP_DEBUG window closed via `set +x` wrap on the inline auth-header compute. • Curated retry-loud error handling on `gh api` bot-user-id lookup and `npx semver`. Pre-merge validation: • 10-reviewer multi-agent code-review pass; 14 findings fixed inline (commit 820cefae), 6 deferred to follow-ups. • End-to-end dry-run rehearsal via workflow_dispatch (run 25919563064) validated route classification, rc-guard, App token mint, RC checkout, version resolver, vtag synthetic-regex check, and faithful tarball pack at the bumped version. • All zizmor findings on the unification commits closed. • Branch-protection required checks all green. Post-merge actions: • After the first successful RC, delete the `NPM_TOKEN` and `RELEASE_PUSH_TOKEN` secrets — they are no longer used. • The first real RC after merge is the live-fire test for steps dry-run could not exercise (atomic tag push, real npm OIDC handshake, GitHub Release creation, docker.yml under explicit secrets passthrough). The if: failure() cleanup step handles the partial-failure recovery automatically; the Rollback Runbook in CONTRIBUTING.md covers the rare cases auto-cleanup can't reach.	2026-05-16 07:46:56 +01:00

Abhigyan Patwari	2620b704e0	feat(cursor): upgrade hooks to Cursor 2.4 postToolUse for Read/Grep/Shell coverage (#1467) ... * feat(cursor): upgrade hooks to Cursor 2.4 postToolUse for Read/Grep/Shell coverage Cursor 2.4 (released 2026-01-22) shipped generic preToolUse/postToolUse hooks matching `Shell|Read|Write|Grep|Delete|Task|MCP:<tool>`, replacing the 2.3-era beforeShellExecution hook that only fired on shell commands. The existing integration only intercepted the shell path, so Cursor users got graph augmentation roughly 10% as often as Claude Code users — only when the agent dropped to rg/grep instead of using its native Read/Grep tools. This swaps the integration over to postToolUse and ports the bash+jq hook script to cross-platform Node: - gitnexus-cursor-integration/hooks/hooks.json: registers a single postToolUse hook matching Shell|Read|Grep that invokes the new gitnexus-hook.cjs. - gitnexus-cursor-integration/hooks/gitnexus-hook.cjs: new Node hook mirroring the safety patterns from the Claude hook (absolute-cwd validation, .gitnexus discovery with linked-worktree fallback, npx.cmd on Windows, end-of-options `--` marker, debug truncation, graceful failure). Extracts the search pattern per tool kind: Grep -> toolInput.query; Read -> file basename stripped to identifier chars; Shell -> existing rg/grep arg parser. Emits Cursor-shape `{ "additional_context": "..." }` on stdout — no shell, no jq. - gitnexus-cursor-integration/hooks/augment-shell.sh: removed (Windows incompatible, narrower coverage). - gitnexus/test/unit/cursor-hook.test.ts: 33 regression tests covering manifest wiring, source-level invariants (no shell:true, npx.cmd, isAbsolute, additional_context output shape, end-of-options marker), extractPattern coverage per tool, and behavioral early-exit paths (empty/invalid stdin, relative cwd, no .gitnexus, unknown tool name, short patterns, non-search shell commands, case-insensitive matching). - README.md / gitnexus/README.md: editor-support table now lists Cursor as Full / hooks=Yes (postToolUse), matching reality. - gitnexus/src/cli/augment.ts and gitnexus/src/core/augmentation/engine.ts: doc-strings updated from `Cursor beforeShellExecution` to `Cursor postToolUse`. Closes #1466. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(cursor): hook timeout is in seconds, not milliseconds Cursor's `timeout` field in hooks.json is in seconds (per https://cursor.com/docs/agent/hooks and the original integration's `"timeout": 5`). I'd written `10000` after blindly copying the issue body's example — that resolves to ~2.8 hours, not 10 seconds. If the script ever hangs before reaching its inner spawnSync timeouts (e.g. during stdin read), Cursor would have waited that long before killing it. Drop to `10` (seconds), matching the Claude plugin's hooks.json and giving plenty of headroom over the inner 7s augment-CLI timeout. Add a regression-guard assertion in cursor-hook.test.ts so a future ms/s mixup fails fast. Reported by Cursor Bugbot on PR #1467. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(cursor): address Claude review findings — payload aliases, debug, install docs Resolves three findings from Claude reviewer on PR #1467: 1. Cursor payload field-name uncertainty (SIGNIFICANT) Claude flagged that the Grep `query` field is an unverified assumption per Cursor 2.4 docs (https://cursor.com/docs/agent/hooks). Mitigated: - Expanded Grep aliases: query | pattern | regex | q | search | searchQuery - Added pickLongestStringValue() last-resort fallback so the hook extracts *something* even if Cursor renames every documented field - Added GITNEXUS_DEBUG=1 stderr logging of the raw stdin payload so users can capture Cursor's actual contract when diagnosing silent no-ops, and report it back if aliases drift - Added Read alias `filePath` (camelCase variant alongside `file_path`) - Inline comment block citing the docs URL and the uncertainty 2. Hook command path resolution + install docs (SIGNIFICANT) Claude flagged `node ./hooks/gitnexus-hook.cjs` as relative without documented install path. Added gitnexus-cursor-integration/README.md with explicit install steps: - .cursor/hooks.json + hooks/gitnexus-hook.cjs at project root - Confirms Cursor's project-root CWD convention with doc link - Verify steps including GITNEXUS_DEBUG capture - Pattern-extraction contract table per tool - Troubleshooting: not-firing, npx fallback, wrong-pattern diagnosis 3. README "Full" overclaim for Cursor (MODERATE) Both README rows now read `Yes (postToolUse, manual install)` linking to the new install README, accurately signaling that hooks aren't automated by `gitnexus setup` like they are for Claude Code. 4. Shell quoted-pattern parser limitation (MINOR, documented) Added inline comment in gitnexus-hook.cjs documenting the known `rg "User Service"` -> `User` truncation, plus regression tests in cursor-hook.test.ts pinning the behavior so a future change is visible. Test additions (33 -> 41): - Wide-alias source coverage for Grep (query / pattern / regex / q / search / searchQuery) plus pickLongestStringValue fallback - Read alias coverage including camelCase filePath - GITNEXUS_DEBUG behavioral test: stderr quiet by default, payload echoed when env var set, stdout output contract preserved either way - Shell quoted-pattern documented behavior tests - Install README presence + content (.cursor/hooks.json, hooks/, debug diagnostics) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>	2026-05-10 13:29:06 +01:00
Alex Macdonald-Smith	d91428ad9d	feat(cli): add gitnexus publish for opt-in understand-quickly registry (#1425) ... * feat(cli): add `gitnexus publish` for opt-in understand-quickly registry Adds a small, opt-in command that fires a single `repository_dispatch` event at `looptech-ai/understand-quickly` to ask the registry for an instant resync of the current repo's entry. No graph file is uploaded; the registry pulls from raw.githubusercontent.com per the protocol at https://github.com/looptech-ai/understand-quickly/blob/main/docs/integrations/protocol.md. - Pure helpers (id parsing, payload construction, validation) live in `gitnexus-shared/src/integrations/understand-quickly.ts` so the package stays Node-free and the same logic is testable in isolation. - The CLI command lives in `gitnexus/src/cli/publish.ts`. Without `UNDERSTAND_QUICKLY_TOKEN` it is a no-op (exits 0 with one informational line); with the token it POSTs the dispatch and surfaces 204 / 401 / 404 / 5xx distinctly. - The id defaults to `<owner>/<repo>` parsed from the `origin` remote and can be overridden with `--id`. - Refuses to publish when no `.gitnexus/` index exists, with a `gitnexus analyze` hint. Tests: a new vitest unit covers the pure helpers (8 + 8 + 2 cases) and the no-token no-op path with a `fetch` spy that fails the test if the network is touched. README gets a one-paragraph "Publishing to understand-quickly" section near the existing CLI docs. * fix(uq-publish): address review blockers + high-severity items Addresses CodeQL polynomial-regex (HIGH), token-gate ordering, distinct 401/403/404/422 response branches, fetch timeout, expanded test coverage, tightened owner/repo validation, and non-GitHub remote rejection. See response thread on PR #1425 for the per-finding rationale. Signed-off-by: amacsmith <alex.mac@looptech.ai> * fix(publish): address Claude review on PR #1425 - AbortError → TimeoutError: AbortSignal.timeout() throws a DOMException with name 'TimeoutError', not Error{name:'AbortError'}. Match the pattern used in core/embeddings/http-client.ts so the user-facing "timed out after 15000ms" message actually fires. Update the regression test to throw a real DOMException — the previous fake was a false-green. - isValidOwnerRepo: forbid trailing hyphen in the owner segment. GitHub rejects this at account-creation time; allowing it here meant hand-typed --id values like 'my-org-/repo' would pass our regex and 422 from GitHub. - Add publish-command coverage to cli-index-help.test.ts (asserts on --id, --skip-git, the registry name, and the token env var) and cli-commands.test.ts (asserts publishCommand is exported as a function). Catches accidental command-registration deletion. --------- Signed-off-by: amacsmith <alex.mac@looptech.ai> Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>	2026-05-09 09:52:26 +01:00
Gergő Magyar	de63418f7e	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.

Scorecard already had it. - Pin every net-new third-party Action to a commit SHA (was: major-tag refs flagged by zizmor as 'unpinned action reference'): github/codeql-action -> v3.35.3 (0daab03) actions/dependency-review-action -> v4.9.0 (2031cfc) gitleaks/gitleaks-action -> v2.3.9 (ff98106) ossf/scorecard-action -> v2.4.3 (4eaacf0) docker/build-push-action -> v6.19.2 (10e90e3) - Bump aquasecurity/trivy-action 0.28.0 -> 0.36.0 (ed142fd). Versions < 0.35.0 are flagged by GHSA-69fq-xp46-6x23 (briefly compromised supply chain). Caught by Dependency Review on the introducing PR. - Pin pipx-installed zizmor to 1.24.1 (was unpinned 'pipx install zizmor' resolving to latest at run time). Removes the now-stale residual-findings doc since every item it recorded is resolved on this branch. * fix(ci-security): clear remaining zizmor findings After landing the new security workflows, zizmor reported 5 high+ findings against pre-existing workflows (none introduced by this PR's new files, all introduced by zizmor's wider scope). Resolved per research at docs.zizmor.sh and PyO3/maturin issue #2425: Real fixes (cache-poisoning): - publish.yml + release-candidate.yml: add 'package-manager-cache: false' to actions/setup-node. setup-node v5+ enables caching by default when a packageManager field is present in package.json; explicit opt-out keeps release installs hermetic and clears the audit. Cost: ~30s slower per release run. Documented exemptions (dangerous-triggers, .github/zizmor.yml): - ci-report.yml: workflow_run is REQUIRED to post sticky comments on fork PRs (forks have read-only GITHUB_TOKEN on pull_request). - claude.yml: pull_request_target is required by claude-code-action to access secrets and post fork-PR review comments. PR checkouts pin fork HEAD SHA to mitigate TOCTOU. - pr-labeler.yml: pull_request_target on the autolabel job needs pull-requests:write. release-drafter runs with dry-run:true and reads config from the BASE ref only. Each exemption carries the documented mitigation in zizmor.yml. workflow-lint.yml now passes --config to both the SARIF and the gate invocations. Local 'zizmor --config .github/zizmor.yml --min-severity high .' reports: No findings to report. Good job!	2026-05-04 08:21:53 +01:00
abhigyanpatwari	2ff3e64f71	docs(readme): fix misleading Web UI section (#1110) ... The "Web UI (browser-based)" section described an old client-side architecture.

Gergő Magyar	ac9246cfd3	ci(docker): mirror signed images to Docker Hub alongside GHCR (#1029) ... * ci(docker): mirror signed images to Docker Hub alongside GHCR docker.yml now publishes to docker.io/abhigyanpatwari/gitnexus{,-web} in the same build step as the existing GHCR push, so both registries receive the same digest, the same Cosign keyless signature, and the same SBOM / build-provenance attestations. The Docker Hub login uses new repo secrets DOCKERHUB_USERNAME / DOCKERHUB_TOKEN (scoped PAT, not account password). Supply-chain guarantees carry over unchanged: the signing loop iterates metadata-action's full tag set, so Docker Hub tags get signed at the identical digest under the same docker.yml@refs/tags/v* identity. The ClusterImagePolicy is extended with docker.io / index.docker.io / bare- namespace globs so admission cannot be sidestepped by registry-prefix choice. README and .env.example document both registries; RC section in CONTRIBUTING.md notes the Docker Hub mirror tag. Closes #1027 * ci(docker): publish to akonlabs Docker Hub namespace; add PR dry-run CI - Hardcode `akonlabs` as the Docker Hub namespace in metadata-action and both attestation subject-names (Docker Hub org differs from GitHub org `abhigyanpatwari`, so `github.repository_owner` would produce the wrong ref) - Update docs (.env.example, README, CONTRIBUTING) and the Kubernetes ClusterImagePolicy globs to reference `akonlabs/gitnexus{,-web}` - Add `pull_request` trigger so the image build runs as CI on every PR (build only — no push, sign, or attestation) - Add `workflow_dispatch` with `dry_run: boolean` (default true) for manual build-only runs; all publish steps gated on `github.event_name != 'pull_request' && !inputs.dry_run`	2026-04-23 18:59:26 +01:00
PhmTuns	ea418c0126	docs: fix group add and group remove usage in READMEs (#1020) ... The top-level and CLI READMEs advertised `gitnexus group add <name> <repo>` (two args) and `gitnexus group remove <name> <repo>`, but the CLI (`gitnexus/src/cli/group.ts`) actually requires three args for `add` (`<group> <groupPath> <registryName>`) and uses `<groupPath>` — not a repo path — for `remove`. Reusing the same second argument across two `group add` invocations silently overwrote the previous mapping because the hierarchy path is the key in `group.yaml`'s `repos` map. Update both READMEs to match the real CLI contract. Node_modules not installed locally for this docs-only change, so pre-commit (prettier + typecheck) was skipped.

Adds 20 new unit tests covering constructor inference, annotation precedence, and known limitations across all supported languages. * fix(type-env): class-aware constructor resolution, multi-declarator fix - Add collectClassNames pre-scan: walks AST to build Set<string> of class/struct names defined in the file - C++ extractInitializer uses classNames.has() to verify identifier is a known class before inferring (auto x = User() resolves, auto x = getUser() does not — no false positives) - Add InitializerExtractor type that receives classNames parameter - Fix env.size gating: always call extractInitializer when available, so mixed declarators like const a: A = x, b = new B() resolve both - Add env.has() guard in Java extractInitializer to skip already-bound vars - Document Rust new/default whitelist rationale - Pin all test assertions, add mixed multi-declarator test case * fix(type-env): resolve Self/self/static/parent to actual type names - Rust: Self::new()/Self::default() resolves to enclosing impl type - PHP: new self()/static() resolves to enclosing class, parent() to superclass - Rust: Tier 0 annotation guard prevents overwrite by constructor inference - Rust: mut_pattern handling in extractVarName for let mut bindings - TS: fix misleading comment in extractInitializer - 58 tests passing (3 new Self/self resolution tests) * perf(type-env): single-pass AST walk with closure-scoped state Refactors buildTypeEnv to use closures instead of passing mutable state as parameters. classNames, env, and config are captured by the inner walk and extractTypeBinding functions — no parameter mutation. - Eliminates separate collectClassNames pre-scan (O(2n) → O(n)) - config looked up once per file instead of per-node - 29 fewer lines * feat(type-env): constructor-inferred type resolution for all languages Add cross-file constructor type inference to the ingestion pipeline, enabling receiver-type disambiguation for member calls like `user.save()` when the variable is assigned from a constructor without explicit type annotations. Pipeline changes: - Add extractInitializer to Python and Swift type extractors - Add CONSTRUCTOR_BINDING_SCANNERS for Python, Swift, C/C++ in type-env - Wire constructorBindings through parse-worker → parsing-processor → pipeline → processCallsFromExtracted - Rewrite resolveCallTarget receiver-type filtering (step D) to use tiered import resolution (same-file → import-scoped → global) before falling back to fuzzy ownerId matching - Use collectTieredCandidates for constructor binding verification instead of raw lookupFuzzy Bug fixes: - Fix C++ inline method query: @definition.method was captured on field_declaration_list instead of function_definition, causing wrong parameterCount for all inline class methods - Fix parse-worker accumulated/flush results missing constructorBindings CI changes: - Add swift.test.ts to ci-integration pipeline group and coverage job - Update ci-report to fetch base branch (main) coverage for delta reporting instead of showing config thresholds - Add per-suite timing breakdown table (unit/integration/total) - Add expandable skipped test details section Tests: 288 passed, 4 skipped (swift — macOS only) across 10 languages - 36 new constructor-inferred integration tests (4 per language) - 10 fixture directories with cross-file constructor patterns - TypeScript, JavaScript, Java, Kotlin, Python, PHP, Rust, Go, C++, Swift * fix(type-extractors): add type assertion for LanguageTypeConfig * feat(ruby): constructor-inferred type resolution and self-receiver mapping Add Ruby User.new constructor binding scanner to type-env, enabling receiver-type disambiguation for member calls like user.save vs repo.save. Add self/this → enclosing class resolution in lookupTypeEnv so self.method() calls resolve to the correct class even when the method name is ambiguous. * docs: update README with constructor inference and self/this resolution details * refactor(ingestion): unified ResolutionContext replaces fragmented map passing Introduce createResolutionContext() as the single resolution API for all processors. Eliminates duplicated tier-selection logic, fixes heritage namedImportMap bug, and adds per-file resolution caching. - NEW resolution-context.ts: closure-factory with resolve(), per-file cache, TIER_CONFIDENCE constant, and shared ResolutionTier type - DELETE symbol-resolver.ts: zero production importers, logic now in resolution-context.ts - call-processor: all functions take ctx instead of 6 separate maps, collectTieredCandidates removed (ctx.resolve replaces it), D4 redundant re-resolve eliminated - heritage-processor: takes ctx, resolveHeritageId helper extracts repeated 14-line fallback pattern, namedImportMap now included - import-processor: takes ctx, dead createImportMap/createPackageMap/ createNamedImportMap factories removed - pipeline: creates single ctx, wires onProgress to all processors, logs cache hit rate in dev mode - Tier renamed: unique-global → global (honest about returning all candidates) - Tests migrated: 1178 unit + 84 integration passing * feat(type-env): self/this/super resolution, TypeEnvironment API, and review fixes Add cross-language receiver keyword resolution: - self/this/$this → enclosing class name via AST walk - super/base/parent → parent class name via heritage AST extraction (8 grammar variants: TS/JS, Java, Python, Ruby, C#, PHP, Kotlin, C++, Swift) - D-phase widening in resolveCallTarget for super→parent method dispatch Introduce TypeEnvironment API replacing loose TypeEnvResult + lookupTypeEnv: - buildTypeEnv() returns TypeEnvironment with .lookup() method - Single-pass AST walk merges constructor binding scan (was separate traversal) - ClassNameLookup type replaces over-broad ReadonlySet<string> facade - Memoized class name lookups to avoid redundant SymbolTable scans Code review fixes (6 agents, 11 findings): - Replace ctx.resolve(name, '') hack with direct symbols.lookupFuzzy() - Extract scope key helpers (extractFuncNameFromScope, receiverKey) - Simplify D-phase from 5 steps to 4 with deduped typeNodeIds - Remove C from CONSTRUCTOR_BINDING_SCANNERS (YAGNI — C has no constructors) - Cache Map reuse in ResolutionContext to reduce GC pressure - Remove unused TieredCandidates import Integration tests for self/this, parent, and super resolution across all 12 supported languages with per-language fixture directories. * fix(type-env): generic parent resolution, TS cast inference, C++ brace-init Fix generic parent class breaking super resolution: - extractParentClassFromNode now uses extractSimpleTypeName to strip generic params (Base<T> → Base) and qualified names (models.Model → Model) - Affects TS, Java, Python, C# heritage extraction Fix TypeScript new X() as T / new X()! missed inference: - Unwrap as_expression and non_null_expression before checking for new_expression in extractInitializer Fix C++ brace-init User{} missed inference: - Handle compound_literal_expression with type_identifier child in extractInitializer Clean up deprecated lookupTypeEnv: - Remove standalone lookupTypeEnv export, migrate all callers to TypeEnvironment.lookup() method - Update all 80+ test assertions to use the new API Integration test fixtures added: - typescript-cast-constructor-inference (new X() as T, new X()!) - typescript/java/csharp/kotlin-generic-parent-resolution - cpp-brace-init-inference (auto x = User{}) * fix(type-extractors): Go &User{}, TS double-cast, Swift .init inference Fix Go pointer-to-struct literal not inferred: - Unwrap unary_expression (address-of &) before composite_literal check - user := &User{} now correctly infers type User Fix TypeScript double-cast only unwrapping one level: - Change if to while loop for nested as_expression/non_null_expression - new User() as unknown as Admin now correctly infers type User Fix Swift User.init(name:) explicit init call missed: - Handle navigation_expression callee with .init suffix in extractInitializer Integration test fixtures: - go-pointer-constructor-inference (&User{}, &Repo{}) - typescript-double-cast-inference (as unknown as T) * feat: Rust struct literal, Python qualified ctor, Go new(), Swift .init scanner - Rust: handle struct_expression in extractInitializer (User { name: "alice" }) - Python: support attribute nodes in extractInitializer (models.User("alice")) and the cross-file scanner — extractSimpleTypeName handles qualified names - Go: handle new(User) built-in in extractGoShortVarDeclaration - Swift: extend CONSTRUCTOR_BINDING_SCANNERS to handle navigation_expression callee for User.init(name:) cross-file resolution Unit tests: 87 → 96 (Rust struct literal, Go new(), Python qualified ctor, Python scanner qualified, plus edge cases) Integration tests: 4 new describe blocks with fixtures * fix: Rust Self{} resolution, C++ scoped brace-init, PHP promotion params, Ruby constants - Rust: resolve Self {} struct literal to enclosing impl type (was stored as "Self") - C++: replace type_identifier guard with extractSimpleTypeName for compound_literal_expression, enabling ns::User{} scoped brace-init (closes previously deferred gap) - PHP: add property_promotion_parameter to TYPED_PARAMETER_TYPES for PHP 8.0+ constructor property promotion (__construct(private Foo $x)) - Ruby: extend extractRubyConstructorBinding to accept constant left-hand side (REPO = Repo.new) Unit tests: 96 → 101 (+5: Rust Self{} ×2, C++ ns::User{} ×1, PHP promotion ×1, Ruby constant ×1) Integration tests: 4 new describe blocks with fixtures * feat: Phase 1 type resolution gaps — walrus, PHP properties, nullable, Go make/assert Phase 1 quick wins from the type resolution gap analysis: 1. Python walrus operator := (named_expression) — extractInitializer + scanner 2. PHP 7.4+ typed class properties — property_declaration in extractDeclaration 3. Nullable union unwrapping — User | null → User in extractSimpleTypeName 4. Go make() builtin — slice/map element type extraction 5. Go type assertions — iface.(User) type extraction Also: PHP primitive_type handling in extractSimpleTypeName (string, int, etc.) Unit tests: 101 → 114 (+13) Integration tests: 8 new describe blocks with fixtures * feat: Phase 2 type resolution gaps — C++ range-for, Rust if-let, C# pattern matching, Python class annotations Phase 2 medium-effort improvements: 1. C++ range-for with explicit type — for (User& u : vec) binds u: User 2. Rust if-let/while-let captured_pattern — user @ User { .. } binds user: User 3. C# is-pattern matching — if (obj is User user) binds user: User 4. Python class-level annotations — confirmed already working, added tests Unit tests: 114 → 127 (+13) Integration tests: 11 new test cases with fixtures	2026-03-14 19:05:49 +00:00

Linus Beckhaus	c4eaf45ab1	feat(hooks): auto-reindex notification with cross-platform hardening (#205) ... Adds PostToolUse hook that detects stale GitNexus index after git mutations (commit, merge, rebase, cherry-pick, pull) and notifies the agent to reindex. Uses lightweight staleness check (git rev-parse HEAD vs meta.json) instead of running gitnexus analyze synchronously, avoiding KuzuDB corruption and 120s blocks. Security and cross-platform hardening: remove shell:true from all spawnSync calls, use .cmd extensions on Windows, add path.isAbsolute(cwd) guards, fix setup.ts path escaping with JSON.stringify, use sendHookResponse() consistently. Includes 73 regression tests.	2026-03-07 08:59:54 +00:00
