charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: shared resilient-fetch (retries + circuit breaker) Add a small, runtime-agnostic resilience layer in gitnexus-shared and migrate every backend HTTP outbound call (CLI, MCP, wiki LLM, web → backend) through it. Helpers (gitnexus-shared/src/integrations/): - retry.ts — withRetry(fn, opts) with caller-supplied retryability classification and full-jitter exponential backoff. - circuit-breaker.ts — closed/open/half-open per-process breaker with injectable clock, plus a keyed registry so callers targeting the same endpoint share state. - resilient-fetch.ts — composed wrapper: retries 5xx + 429 + retryable network throws, treats AbortSignal.timeout() and 4xx (other than 429) as terminal, honors Retry-After (capped at 30s), throws CircuitOpenError when the breaker opens. Migrations (no behaviour regression — all existing tests pass): - gitnexus/src/core/embeddings/http-client.ts (covers analyze + MCP query path) — replaces inline linear-backoff retry. - gitnexus/src/core/wiki/llm-client.ts — preserves Azure content-filter branch; resilientFetch handles 5xx/429. - gitnexus-web/src/services/backend-client.ts (fetchWithTimeout helper) — small retry budget (2 attempts, 250–1500 ms) so a dead local backend still fails fast for the user. - gitnexus-web/src/core/llm/settings-service.ts (OpenRouter model list). Deliberately not migrated: - gitnexus-web/src/services/backend-client.ts streamJob() — Server-Sent Events stream; the existing reconnect-with-Last-Event-ID logic is not unary-fetch shaped. - gitnexus-web/src/components/SettingsPanel.tsx checkOllamaStatus() — one-shot health probe; retrying delays the "Ollama not running" error rather than improving UX. 41 new helper tests cover backoff math, breaker state transitions, Retry-After parsing (delta-seconds + HTTP-date), 401/422 terminal classification, and breaker fail-fast on three exhausted retry batches. * fix(review): apply autofix feedback Address Claude's two MEDIUM blocking findings on PR #1448 plus the CodeQL SSRF false-positive flag. - backend-client `fetchWithTimeout` now uses `AbortSignal.timeout()` merged with the caller's signal via `AbortSignal.any()`. Timer-fired aborts surface as `DOMException(name='TimeoutError')` so resilientFetch routes them through the terminal-network branch (no retry, no breaker hit), instead of incrementing the breaker for user-side network slowness. - Method-aware retry budget in `fetchWithTimeout`: idempotent verbs (GET/HEAD/OPTIONS) keep the 2-attempt budget; POST/PATCH/PUT/DELETE default to single-attempt so a 5xx on `startAnalyze` cannot start a duplicate job. New `forceRetry` parameter for callers that know-idempotent mutations (e.g. DELETE of a known-deleted resource). - `resilient-fetch.ts` carries a documented suppression for CodeQL js/server-side-request-forgery on the inner fetch call. Every concrete caller passes a hardcoded URL constant or a value from configuration (env vars, saved settings); user request input never flows into the URL parameter. - New test file `backend-client-retry.test.ts` covers all three paths: GET retries on 503, POST does not retry, timeout does not increment the breaker. * fix(resilient-fetch): address Codex adversarial findings Closes the three blocking issues from Codex's review on PR #1448. U1 — Add `recordNeutral()` to CircuitBreaker. Third outcome path that's an explicit no-op for state and the consecutive-failure counter. Distinct from `recordSuccess` (closes the breaker) and `recordFailure` (may open it). Used for outcomes that are neither evidence of backend health nor evidence of backend failure. U2 — Route terminal-client / terminal-network through `recordNeutral`. Previously a 401 or local timeout called `recordSuccess`, which reset `consecutiveFailures` to 0. A 5xx → 401 → 5xx → 401 → 5xx sequence would NEVER trip the breaker because each 4xx in between erased the running count. Also classify external `AbortError` as terminal-network (was retryable-network), so caller-driven cancellation no longer retries against an already-aborted signal or counts toward breaker failures on exhaustion. U3 — Per-origin breaker key in web `fetchWithTimeout`. Was hardcoded to `'web-backend'` even though `_backendUrl` is mutable via `setBackendUrl`. Switching backend URLs after a circuit tripped on host-A would strand the user during the full cooldown. Key is now `web-backend:`, so each backend URL gets its own breaker state. Tests: +5 recordNeutral, +4 resilient-fetch (interleaved 4xx/5xx, external AbortError, prior-state preservation), +1 web switch-backend regression. All 70 gitnexus integration tests + 15 web tests green. * fix(resilient-fetch): tolerate header-less fetch mocks on 429 `classifyOutcome` called `resp.headers.get('Retry-After')` directly, which crashed when a test stubs `fetch` with a plain object like `{ ok: false, status: 429 }` (no `headers` field). Real `Response` always has Headers, so this surfaces only in test setups, but the helper has no business assuming caller-side correctness on this — the defensive guard is cheap and a missing `Retry-After` falls through to exponential-backoff retry like any 429 without the header. Surfaced by `gitnexus/test/unit/http-embedder.test.ts > retries on rate limit`, which the embeddings migration exercises against a plain-object 429 stub. Locked in with a new `classifies 429 from a header-less fetch mock without throwing` case. * fix(review): apply autofix feedback Closes findings from the third multi-agent review pass on PR #1448. #1 (P1) callLLM had no per-attempt timeout Wiki LLM calls passed no `signal` to resilientFetch; each of three retry attempts could hang indefinitely on a frozen TCP connection. Add `signal: AbortSignal.timeout(60_000)` so the per-attempt budget matches what http-client.ts and backend-client.ts already provide. #2 (P2) drop dead `lastRetryableResp` post-loop fallback Variable was set in one switch arm but only read in unreachable code after the loop. The retry loop always returns/throws on every iteration. Keep only the defensive `throw` so TypeScript's control-flow analysis still sees `Promise` as the return. #5 (P2) gate test-only exports behind a subpath `__resetBreakerRegistry__` and `classifyOutcome` were reachable from the main `gitnexus-shared` barrel — production code calling `__resetBreakerRegistry__` from a tool implementation would silently nuke every circuit breaker process-wide. Move to a new `gitnexus-shared/test-helpers` subpath export. Production callers see the cleaner public API; tests import via the explicit `gitnexus-shared/test-helpers` path. #6 (P2) exhaustiveness guard on Outcome switch Add a `default: const _: never = outcome` arm so a future sixth `Outcome.kind` won't compile silently — it'll surface at the switch site rather than fall through to a retry/no-retry default. #9 (P3) document cumulative wall-clock budget Add a "Cumulative wall-clock budget" paragraph to resilientFetch's JSDoc explaining the worst-case total wait (`maxAttempts × (per-attempt timeout + capDelayMs)` ≈ 60s with defaults) and pointing callers at outer `AbortSignal.timeout()` when they want a tighter bound. Deferred to follow-up PRs (per review's Auto-resolve recommendation): - #3 idempotency knob to shared API (forceRetry into ResilientFetchOptions) - #4 publish.ts migration to resilientFetch - #7 parseRetryAfter past-HTTP-date / negative-seconds asymmetry - #8 recordNeutral counter time-decay (documented breaker semantic) * fix(circuit-breaker): gate half-open to a single in-flight probe Closes the Codex adversarial-review finding on PR #1448 that flagged a recovery-time thundering herd: when cooldown expired, every concurrent caller transitioned the breaker to half-open and probed the still- recovering dependency in lockstep, defeating the breaker's "fail fast" promise. U1 — probe-permit gate in CircuitBreaker.check() Added a `probeInFlight: boolean` field. After cooldown expires, the first `check()` admits the probe and consumes the permit; subsequent callers throw `CircuitOpenError` with a configurable `halfOpenRetryAfterMs` (default 1000ms) until the probe resolves. Critical design point: `recordNeutral` now RELEASES the permit but does NOT transition state. Without that split, a single `TimeoutError` from per-attempt `AbortSignal.timeout` (which routes through neutral classification) would permanently park the breaker in half-open. By separating permit-release from state-resolution, we keep the "neutral doesn't claim health" semantic without creating that wedge. Other changes: - `halfOpenRetryAfterMs` is now a constructor option for consumers with long-running protected ops (LLM streaming, large uploads). - `getState()` is documented as a pure read; the implicit Open -> Half-Open transition lives in `check()` only, so tests that inspect state never inadvertently consume a probe permit. - `isProbeInFlight()` test-only accessor for assertion clarity. - JSDoc on `check()` records the JS event-loop atomicity dependency and the load-bearing `try/finally` pairing invariant. U2 — End-to-end concurrency regression through resilientFetch Three new scenarios in resilient-fetch.test.ts (26 -> 29): - 3 concurrent calls + probe gets 200 -> 1 hits fetch, 2 throw CircuitOpenError, breaker closes. - 3 concurrent calls + probe gets 503 -> ResilientFetchExhaustedError on probe; concurrent callers see halfOpenRetryAfterMs (1000ms); fresh caller after probe resolves sees the FULL new cooldown (10000ms), not the probe-in-flight default. - Probe cancelled mid-flight via AbortError -> permit released, state stays half-open, next caller becomes the new probe and succeeds. Plus 9 new circuit-breaker unit tests (16 -> 25) covering the permit gate, recordNeutral-releases-permit semantic, fresh-cooldown distinction, default vs configurable halfOpenRetryAfterMs, getState() purity, and the three-probes-via-neutrals chain. Total integration test count: 70 -> 82. All 106 gitnexus + 15 web tests pass; both packages typecheck. Maintainer decisions (deferred per plan 003 Open Questions): - Plan 002's deferral judgement was reversed on Codex's argument without new measurement / incident data. The reversal is defensible on principle (Hystrix / Resilience4j alignment) but lacks workload- driven evidence. - Probe-blocked callers throw silently (no log / event hook). R4's "no new public API" prevents adding observability; loosen if a debug log on probe-blocked is wanted. * refactor(embeddings): replace bespoke HF breaker with shared CircuitBreaker Deleted the local `HfDownloadCircuitBreaker` class and the manual retry loop in `withHfDownloadRetry`. Both are now backed by the shared `gitnexus-shared` primitives: - `hfDownloadCircuit` is `new CircuitBreaker({ failureThreshold, cooldownMs, key: 'hf-download' })` — same state machine as before PLUS the single-permit half-open gate that prevents recovery-time stampedes when CLI + MCP embedders concurrently re-load the model. - `withHfDownloadRetry` delegates the loop to `withRetry` from the shared package. Per-attempt timeout (`withDownloadTimeout`), network-vs-non-network classification, circuit recording, and the `onRetry` callback wire through `withRetry`'s `isRetryable` callback. Behaviour preserved: - Pre-flight `CIRCUIT_OPEN_TAG` rejection when the breaker is open. - Mid-loop `CIRCUIT_OPEN_TAG` "opened after N consecutive failures" when a network error trips the threshold. - Non-network errors (e.g. CUDA unavailable) bypass retry and go through `recordNeutral` instead of resetting the breaker's failure-count progress. - `onRetry(attempt+1, max, err)` fires only when there's a next attempt, matching the prior semantic. Generic CircuitBreaker gained two inspection accessors: - `getOpenedAt(): number | null` - `getCooldownMs(): number` Used by `withHfDownloadRetry` to compute `secsUntilReset` without consuming a probe permit (which `check()` would do). Test consolidation: the 7 bespoke `HfDownloadCircuitBreaker` state-machine tests in hf-env.test.ts were 1:1 duplicates of existing tests in `circuit-breaker.test.ts` and were deleted. Remaining 42 hf-env tests all pass; full integration sweep (148 gitnexus + 15 web) green. --- gitnexus-shared/package.json | 4 + gitnexus-shared/src/index.ts | 16 + .../src/integrations/circuit-breaker.ts | 273 +++++++++ .../src/integrations/resilient-fetch.ts | 279 +++++++++ gitnexus-shared/src/integrations/retry.ts | 105 ++++ gitnexus-shared/src/test-helpers.ts | 13 + gitnexus-web/src/core/llm/settings-service.ts | 6 +- gitnexus-web/src/services/backend-client.ts | 85 ++- .../test/unit/backend-client-retry.test.ts | 110 ++++ gitnexus/src/core/embeddings/hf-env.ts | 179 +++--- gitnexus/src/core/embeddings/http-client.ts | 64 +- gitnexus/src/core/wiki/llm-client.ts | 146 +++-- gitnexus/test/unit/hf-env.test.ts | 130 +--- .../unit/integrations/circuit-breaker.test.ts | 395 +++++++++++++ .../unit/integrations/resilient-fetch.test.ts | 558 ++++++++++++++++++ gitnexus/test/unit/integrations/retry.test.ts | 128 ++++ 16 files changed, 2173 insertions(+), 318 deletions(-) create mode 100644 gitnexus-shared/src/integrations/circuit-breaker.ts create mode 100644 gitnexus-shared/src/integrations/resilient-fetch.ts create mode 100644 gitnexus-shared/src/integrations/retry.ts create mode 100644 gitnexus-shared/src/test-helpers.ts create mode 100644 gitnexus-web/test/unit/backend-client-retry.test.ts create mode 100644 gitnexus/test/unit/integrations/circuit-breaker.test.ts create mode 100644 gitnexus/test/unit/integrations/resilient-fetch.test.ts create mode 100644 gitnexus/test/unit/integrations/retry.test.ts diff --git a/gitnexus-shared/package.json b/gitnexus-shared/package.json index 7c1e6847a..0a5d7a2db 100644 --- a/gitnexus-shared/package.json +++ b/gitnexus-shared/package.json @@ -10,6 +10,10 @@ ".": { "types": "./dist/index.d.ts", "default": "./dist/index.js" + }, + "./test-helpers": { + "types": "./dist/test-helpers.d.ts", + "default": "./dist/test-helpers.js" } }, "scripts": { diff --git a/gitnexus-shared/src/index.ts b/gitnexus-shared/src/index.ts index faf136fe7..3c82658f1 100644 --- a/gitnexus-shared/src/index.ts +++ b/gitnexus-shared/src/index.ts @@ -143,6 +143,22 @@ export type { ScopeTree } from './scope-resolution/scope-tree.js'; export { buildPositionIndex } from './scope-resolution/position-index.js'; export type { PositionIndex } from './scope-resolution/position-index.js'; +// Resilient fetch primitives — bounded retries + per-process circuit breaker. +// Test-only helpers (`__resetBreakerRegistry__`, `classifyOutcome`) are +// reachable via the separate `gitnexus-shared/test-helpers` subpath; do +// NOT add them here.

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(autofix): verify reviewdog actually posted before claiming "click Apply" The sticky summary comment was stating "Posted formatting suggestions inline. Click Apply suggestion on each" even when reviewdog landed zero inline review comments — typical case: the formatter touched lines outside the PR's added range, so `-filter-mode=added` (correctly) filtered everything out. The script unconditionally set `posted=true` after running reviewdog regardless of whether any comments were actually created, leaving the user staring at a sticky that promised buttons that didn't exist. The publish job now snapshots the count of `github-actions[bot]` review comments before and after reviewdog. If the delta is zero, surface a new `diff-no-overlap` UI state that tells the user plainly: "Formatter found fixable issues, but they're on lines outside this PR's added range — there's nothing to click here. Run locally: npm run lint:fix && npm run format." Plus a matching `gitnexus/autofix` Check Run conclusion (still neutral, distinct title) so agents reading `gh pr checks` see the same signal. Three states are now machine-distinguishable in the sticky's gitnexus-autofix JSON block: suggestions-posted (delta > 0), diff-no-overlap (delta == 0), skipped-too-large (>3k lines). * feat(autofix): replace inline reviewdog with /autofix ChatOps button Pivot the PR autofix UX from per-line reviewdog suggestions to a single slash-command button. Contributors comment `/autofix` on the PR; a new trusted workflow downloads the existing autofix patch artifact, applies it to the PR head, and pushes a commit back. Why: - 3K+ diffs hit GitHub's review-comment API 406 limit -> dead end. - Diffs where the formatter touches lines outside the PR's added range ("no-overlap") get filtered by reviewdog's -filter-mode=added -> dead end (PR #1457 patched the lying sticky but the underlying UX gap remained). - Per-line click-Apply-suggestion is high-friction for big diffs and easy to apply unevenly. - A single `git apply` + push works at any size and lands fixes atomically. Changes: - pr-autofix-publish.yml: remove `Install reviewdog` and `Post inline suggestions` steps. Collapse three sticky states (suggestions-posted, diff-no-overlap, skipped-too-large) into one (fixes-available). Bump JSON schema v1 -> v2 with `apply_command` field; all v1 fields preserved. - pr-autofix-apply.yml (new): triggers on issue_comment with body `/autofix`, validates body via strict regex, validates commenter has write/admin/maintain or is the PR author, locates latest successful pr-autofix run for PR head SHA, downloads artifact, applies patch, pushes commit. Reacts +1/-1/eyes on triggering comment per outcome. Idempotent (`git apply --check --reverse` detects already-applied state). - CONTRIBUTING.md: document v2 schema and the /autofix flow, including the maintainer-edit requirement for fork PR pushes. Trust posture: apply workflow runs from default-branch code only, under issue_comment trigger. Comment body and author login flow through env vars and pattern-matched, never interpolated into shell. Permission gate (write/admin/maintain OR PR author) before any artifact fetch. Fork PRs require "Allow edits by maintainers" (GitHub-native; we don't bypass). Net YAML: -139 lines in publish.yml, +260 in apply.yml. Removes reviewdog binary pin and the entire review-comment API surface. * fix(autofix): address Codex adversarial findings on PR #1458 Two findings from the Codex adversarial review of the autofix ChatOps pivot. Both are localized YAML changes that close trust gaps the pivot inherited from the original PR #1446 design. U1 — Cross-verify metadata against workflow_run authority (.github/workflows/pr-autofix-publish.yml): Previously the trusted publisher accepted pr_number, head_sha, and head_repo from metadata.json after only an allowlist regex. A fork-controlled `npm run lint:fix` could have written a syntactically valid metadata.json referencing another PR/SHA, redirecting the write-scoped sticky/check-run onto an attacker-chosen target. New `Verify metadata against workflow_run authority` step compares artifact-claimed identity against: - github.event.workflow_run.head_sha - github.event.workflow_run.head_repository.full_name - workflow_run.pull_requests[].number (within-repo PRs) - gh api commits/{sha}/pulls fallback (fork PRs, where pull_requests[] is empty) Fail closed on mismatch — no sticky, no check-run, no override. U2 — Lease-protected push in apply workflow (.github/workflows/pr-autofix-apply.yml): Previously the apply step pushed `HEAD:${HEAD_REF}` plain. A force- push between resolve (Step 5) and push (Step 9) would silently fast-forward an older commit graph over the contributor's newer state. Push now uses `--force-with-lease=refs/heads/${HEAD_REF}:${HEAD_SHA}` against the SHA resolved earlier. Distinct `lease-failed` result code + retry-message reply, separated from `push-failed` (fork without maintainer-edit) so contributors can diagnose the actual cause. Plan: docs/plans/2026-05-09-005-fix-autofix-codex-adversarial-findings-plan.md (local-only per repo convention). Trust posture preserved: no new permissions, no new workflows, no contract change. JSON v2 schema unchanged. CodeQL js/server-side- request-forgery and template-injection posture unchanged — all new inputs flow via env vars and pattern-matched. * fix(autofix): close zizmor credential-persistence finding on apply checkout actions/checkout's default behavior writes the GITHUB_TOKEN into .git/config as an extraheader. The token then sits on disk in the checkout directory — an actions/upload-artifact step on that directory would leak it. We don't upload, but zizmor's credential-persistence lint correctly flags the latent risk. Set persist-credentials: false on the Checkout PR head step. Provide push auth inline via `git -c http.extraheader="Authorization: Basic "` so the credential never lands on disk and never appears in process listings (the URL form https://x-access-token:TOKEN@… is rejected here because it leaks via ps and git remote -v). Push lease semantics from U2 unchanged — same --force-with-lease against the resolved HEAD_SHA, same lease-failed/push-failed/stale result codes. * fix(review): apply autofix feedback ce-code-review surfaced 15 findings on PR #1458; this commit applies the 7 with concrete fixes (#1, #2, #3, #4, #5, #9, #13). Five P2 findings (#6, #7, #8, #10, #12) are recorded as residual actionable work for follow-up; two advisory items (#11, #14) skipped. #1 — applied_run_id schema drift (CONTRIBUTING.md): v2 docs claimed `state: applied` enum value and an `applied_run_id` field that no code path emits. Trimmed docs to match what the workflow actually writes (state: fixes-available; v1 field set as superset). Implementing the apply-side sticky upsert that would populate `applied_run_id` is deferred — cleaner than carrying a contract claim with no code. #2 — result= unset between idempotency probe and lease push (pr-autofix-apply.yml): After `git apply --check` passed, an early non-zero exit from `git config` / `git apply` / `git add` / `git commit` left `result=` unset, sending the user to the `*` "unexpected state (`unknown`)" arm. Wrapped the apply/commit phase in a single if-test that sets `result=apply-failed` on any failure. New React-and-reply branch surfaces an actionable message. #3 — permission lookup conflated transient API failures with denial (pr-autofix-apply.yml): `gh api … 2>/dev/null || echo "none"` swallowed 5xx, 429 secondary rate-limit, and network failures, surfacing them as a public 👎 refusal to legitimate maintainers. Now distinguishes 404 (genuine non-collaborator) from other API failures via stderr match. New `allowed=api-failed` state triggers a 😕 reaction with a "transient API failure, retry" reply instead of a misleading refusal. #4 — lease-failure grep missed git's "remote rejected" / branch- deleted phrasings (pr-autofix-apply.yml): Real lease failures got classified as `push-failed` → user told to enable maintainer-edit, which won't help. Expanded regex to match `remote rejected` and `! [rejected]`. #5 — broken bullet continuation in CONTRIBUTING.md release-candidate section: rejoined the split bullet so it renders correctly. #9 — base64 GITHUB_TOKEN bypassed GitHub's secret-masker (pr-autofix-apply.yml): Added `::add-mask::${auth_header}` immediately after construction so any subsequent log line (set -x, GIT_TRACE) gets *** redacted. #13 — misleading schema-bump comment in pr-autofix-publish.yml: Comment claimed all v1 fields preserved exactly, but the `state` enum was redefined v1→v2. Updated to make the migration path explicit (v1 readers see unfamiliar schema, fall back to prose). Residual actionable work (deferred to follow-up): #6 locate step gh api retry; #7 artifact-expired graceful fallback; #8 re-entrancy comment-spam guard; #10 producer-still-running UX; #12 gh_retry wrapper for apply.yml. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK. * fix(autofix): apply remaining ce-code-review residual findings (#6, #7, #8, #10, #12) Pulls the deferred items from the previous review pass into this PR so the workflow ships with full reliability + UX coverage rather than follow-up debt. #6 + #12 — gh_retry wrapper on idempotent GETs in apply.yml: Permission lookup, PR metadata fetch, and workflow-run lookup are now wrapped in the same gh_retry helper publish.yml uses (3 attempts, linear backoff). Reaction/comment POSTs remain unwrapped (retrying POST would dupe the resource). #10 — producer-still-running UX: The locate step now distinguishes three cases via `found_status` output: success (proceed), in-progress / queued / pending / waiting (reply ⏳ "wait for autofix run to finish"), not-found (reply 🤔 "push a commit"), api-failed (reply ⚠️ "transient API failure"). The "no successful autofix run" message no longer fires immediately after a fresh push while the producer is still mid-run. #7 — artifact-expired graceful fallback: actions/download-artifact gains `continue-on-error: true`. The apply step distinguishes patch-file-missing (artifact expired, 1-day retention elapsed) from patch-file-zero-bytes (formatter found nothing). New `result=artifact-expired` case + ⏳ "push a new commit to regenerate" reply. #8 — re-entrancy loop guard: After checkout but before applying, check if HEAD itself is a github-actions[bot] `chore(autofix)` commit. If so, refuse to re-apply (`result=loop-prevented`) with a 🔁 reply telling the user to push a human-authored commit or revert before retrying. Prevents formatter-config-drift loops where an automated agent watching the sticky could pump arbitrary apply commits. Net effect: every code path in apply.yml now sets a meaningful `result=` that maps to a specific user-facing reaction + reply. The `*` "unexpected state (unknown)" arm becomes truly unreachable in normal operation. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK. * fix(autofix): refresh stale reviewdog comments + reject patches touching .github/ Two follow-up findings on PR #1458: #1 — Stale reviewdog references in workflow header comments: pr-autofix-publish.yml's header still described the removed inline- suggestion path ("posts inline review-comment suggestions to the PR using `reviewdog`", "Reviewdog reporter: github-pr-review reads $REVIEWDOG_GITHUB_API_TOKEN…"). The Check Run permissions comment enumerated the old outcomes (clean / suggestions-posted / skipped-too-large) instead of the current set (clean / fixes- available). pr-autofix.yml's header described the trusted job as posting "inline review-comment suggestions" and the changed_lines comment referenced the dead 3000-line cap. Refreshed all three to describe the actual sticky + Check Run + /autofix flow. #2 — Reject patches touching .github/ (sensitive-paths guard): Theoretical supply-chain vector: a malicious PR could ship a custom prettier/ESLint config that reformats workflow YAML, dependabot.yml, or CODEOWNERS. The producer would capture those edits in autofix.patch; a maintainer running `/autofix` would push them under `contents: write` without human review. The default GITHUB_TOKEN lacks the `workflows` scope so workflow-file pushes would fail at the platform layer anyway, but as a generic `push-failed` (which misleads users into enabling maintainer-edit). Reject early with a specific reason. Match runs against the patch with grep on `^(diff --git|---|+++) [ab]?/?\.github/`. New `result=sensitive-paths` case + 🛑 reply telling the user to apply .github/ formatter changes manually. Documented the constraint in CONTRIBUTING.md under the /autofix section so contributors aren't surprised when the workflow refuses a patch that includes formatter changes to workflow files. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK. --- .github/workflows/pr-autofix-apply.yml | 595 +++++++++++++++++++++++ .github/workflows/pr-autofix-publish.yml | 178 +++---- .github/workflows/pr-autofix.yml | 16 +- CONTRIBUTING.md | 76 +-- 4 files changed, 739 insertions(+), 126 deletions(-) create mode 100644 .github/workflows/pr-autofix-apply.yml diff --git a/.github/workflows/pr-autofix-apply.yml b/.github/workflows/pr-autofix-apply.yml new file mode 100644 index 000000000..b2ec8495f --- /dev/null +++ b/.github/workflows/pr-autofix-apply.yml @@ -0,0 +1,595 @@ +name: PR Autofix (apply) + +# CHATOPS HALF of the autofix pipeline. +# +# Triggered when a contributor comments `/autofix` on a PR.

charset=UTF-8 Content-Transfer-Encoding: 8bit * Initial plan * chore(security): harden workflow permissions and pin Docker base image digests Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/2ddc8f2b-7355-48cf-9a0b-c06df66c3f47 * fix(security): restore permissions: {} on publish + release-candidate workflows These two release-publishing workflows had permissions: {} (the strictest valid form) before PR #1454, which replaced it with permissions: read-all. Every job in both files already declares its own permissions block, so the workflow-level default is only the safety net for future jobs added without one — read-all weakens that net for no benefit. Restore {} and the explanatory comment. Scorecard's TokenPermissions check accepts both forms, so this preserves U9 compliance. * fix(security): narrow permissions: read-all to contents: read on 13 workflows PR #1454 added permissions: read-all to 13 workflows that previously had no top-level permissions block. read-all is Scorecard-compliant but unnecessarily broad — every job in scope only needs contents:read at the workflow level (job-level blocks already grant the writes that any job actually performs). Snapshot of every job in the 13 workflows confirms contents:read is sufficient: - ci.yml: quality/tests/scope-parity have explicit contents:read job blocks; save-pr-meta uses upload-artifact only (no token scopes needed); ci-status is pure shell. - ci-e2e.yml, ci-quality.yml, ci-scope-parity.yml, ci-tests.yml: all jobs do checkout + npm + tsc/vitest/playwright/upload-artifact only; no API token scopes required. - claude.yml, codeql.yml, dependency-review.yml, docker.yml, gitleaks.yml, pr-labeler.yml, trivy.yml, workflow-lint.yml: all jobs already declare their own job-level blocks (security-events:write, pull-requests:write, packages:write, etc.) so the workflow-level default does not gate them. zizmor (--min-severity high) is clean on the resulting tree. Pre-existing medium findings (secrets-inherit, artipacked) are in unrelated workflows and untouched by this commit. scorecard.yml also uses read-all but pre-existed PR #1454 and is deferred to a follow-up PR per the plan's scope boundary. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Gergő Magyar --- .github/workflows/ci-e2e.yml | 3 +++ .github/workflows/ci-quality.yml | 3 +++ .github/workflows/ci-scope-parity.yml | 3 +++ .github/workflows/ci-tests.yml | 3 +++ .github/workflows/ci.yml | 3 +++ .github/workflows/claude.yml | 3 +++ .github/workflows/codeql.yml | 3 +++ .github/workflows/dependency-review.yml | 3 +++ .github/workflows/docker.yml | 3 +++ .github/workflows/gitleaks.yml | 3 +++ .github/workflows/pr-labeler.yml | 3 +++ .github/workflows/publish.yml | 1 + .github/workflows/trivy.yml | 3 +++ .github/workflows/workflow-lint.yml | 3 +++ 14 files changed, 40 insertions(+) diff --git a/.github/workflows/ci-e2e.yml b/.github/workflows/ci-e2e.yml index af0e2758d..96b0a4b26 100644 --- a/.github/workflows/ci-e2e.yml +++ b/.github/workflows/ci-e2e.yml @@ -3,6 +3,9 @@ name: E2E Tests on: workflow_call: +permissions: + contents: read + jobs: check-changes: name: Check web module changes diff --git a/.github/workflows/ci-quality.yml b/.github/workflows/ci-quality.yml index cc334fcaa..a81876d9d 100644 --- a/.github/workflows/ci-quality.yml +++ b/.github/workflows/ci-quality.yml @@ -3,6 +3,9 @@ name: Quality Checks on: workflow_call: +permissions: + contents: read + jobs: format: runs-on: ubuntu-latest diff --git a/.github/workflows/ci-scope-parity.yml b/.github/workflows/ci-scope-parity.yml index cffdeb341..8e2926ba8 100644 --- a/.github/workflows/ci-scope-parity.yml +++ b/.github/workflows/ci-scope-parity.yml @@ -28,6 +28,9 @@ name: Scope Resolution Parity on: workflow_call: +permissions: + contents: read + jobs: discover: name: Discover migrated languages diff --git a/.github/workflows/ci-tests.yml b/.github/workflows/ci-tests.yml index 7010ee6f3..b044d9318 100644 --- a/.github/workflows/ci-tests.yml +++ b/.github/workflows/ci-tests.yml @@ -3,6 +3,9 @@ name: Tests on: workflow_call: +permissions: + contents: read + jobs: tests: name: ubuntu / coverage diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 3059a34dd..dd07337b7 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -6,6 +6,9 @@ on: paths-ignore: ['**.md', 'docs/**', 'LICENSE'] workflow_call: +permissions: + contents: read + # Concurrency convention: see CONTRIBUTING.md → "GitHub Actions — Concurrency Convention". # Hardcoded `CI-` prefix (not `${{ github.workflow }}`) because this workflow is # invoked as a reusable workflow from publish.yml and release-candidate.yml.

Replace the methodology with four stacked techniques: 1. Warmup runs before timing (let the JIT tier up) 2. Median of 5 trials per measurement (eliminates GC + jitter) 3. 4x input ratio (was 2x) - linear gives ~4x, O(n^2) gives ~16x 4. 8x ratio bound with a 20ms noise floor on the LARGE measurement Headroom: linear is expected at ~4x, bound is 8x = 2x safety margin. A real O(n^2) regression on a 4x input would clock 16x, well outside. Catastrophic backtracking is still caught by the absolute <500ms cap. Verified: 10 consecutive local runs all passed. * test(u8): address PR #1475 review — tighten floor + rename for accuracy Two follow-ups from Claude's review: 1. Floor semantics: revert to 'skip when BOTH measurements below floor' (AND, not single-check) and lower threshold from 20ms back to 5ms. Median-of-5 makes 5ms reliably resolvable above performance.now()'s ~10-100us band, so the higher floor was unnecessary defense. Closes the gap where an O(n^2) regression on a fast runner could stay under 500ms AND below 20ms-large to escape both detectors. 2. Rename assertSubLinearRatio -> assertNearLinearScaling. The bound is SIZE_RATIO * 2 = 8x on a 4x input = sub-quadratic with 2x headroom over linear, not strict sub-linearity. New name reflects the actual semantics. --- .../unit/u8-redos-resource-exhaustion.test.ts | 169 ++++++++++-------- 1 file changed, 98 insertions(+), 71 deletions(-) diff --git a/gitnexus/test/unit/u8-redos-resource-exhaustion.test.ts b/gitnexus/test/unit/u8-redos-resource-exhaustion.test.ts index 6dd6d9955..fb5b66cb1 100644 --- a/gitnexus/test/unit/u8-redos-resource-exhaustion.test.ts +++ b/gitnexus/test/unit/u8-redos-resource-exhaustion.test.ts @@ -21,85 +21,112 @@ import { } from '../../src/core/group/cross-impact.js'; /** - * Time a single regex.exec call.

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) * 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.

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) --------- Co-authored-by: Claude Opus 4.7 (1M context) Co-authored-by: Gergő Magyar --- README.md | 2 +- gitnexus-cursor-integration/README.md | 89 ++++ .../hooks/augment-shell.sh | 50 -- .../hooks/gitnexus-hook.cjs | 259 ++++++++++ gitnexus-cursor-integration/hooks/hooks.json | 8 +- gitnexus/README.md | 2 +- gitnexus/src/cli/augment.ts | 2 +- gitnexus/src/core/augmentation/engine.ts | 4 +- gitnexus/test/unit/cursor-hook.test.ts | 458 ++++++++++++++++++ 9 files changed, 815 insertions(+), 59 deletions(-) create mode 100644 gitnexus-cursor-integration/README.md delete mode 100644 gitnexus-cursor-integration/hooks/augment-shell.sh create mode 100644 gitnexus-cursor-integration/hooks/gitnexus-hook.cjs create mode 100644 gitnexus/test/unit/cursor-hook.test.ts diff --git a/README.md b/README.md index 6beadb63d..3c3a28c27 100644 --- a/README.md +++ b/README.md @@ -120,7 +120,7 @@ To configure MCP for your editor, run `npx gitnexus setup` once — or set it up | Editor | MCP | Skills | Hooks (auto-augment) | Support | | --------------------- | --- | ------ | -------------------- | -------------- | | **Claude Code** | Yes | Yes | Yes (PreToolUse + PostToolUse) | **Full** | -| **Cursor** | Yes | Yes | — | MCP + Skills | +| **Cursor** | Yes | Yes | Yes (postToolUse, [manual install](gitnexus-cursor-integration/README.md#hook-install)) | **Full** | | **Codex** | Yes | Yes | — | MCP + Skills | | **Windsurf** | Yes | — | — | MCP | | **OpenCode** | Yes | Yes | — | MCP + Skills | diff --git a/gitnexus-cursor-integration/README.md b/gitnexus-cursor-integration/README.md new file mode 100644 index 000000000..0da8b1981 --- /dev/null +++ b/gitnexus-cursor-integration/README.md @@ -0,0 +1,89 @@ +# GitNexus — Cursor integration + +Static config that adds GitNexus knowledge-graph augmentation and skill files to Cursor. + +> **Hooks require Cursor 2.4+.** Earlier versions don't expose `postToolUse` and the hook will silently no-op. + +## What you get + +| Layer | What it does | How it's installed | +| ------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- | +| **MCP** | `gitnexus` MCP server with 16 tools (`query`, `context`, `impact`, `detect_changes`, `rename`, …) | `npx gitnexus setup` writes `~/.cursor/mcp.json` automatically. | +| **Skills** | `/gitnexus-exploring`, `/gitnexus-debugging`, `/gitnexus-impact-analysis`, `/gitnexus-refactoring`, `/gitnexus-pr-review` markdown skills | `npx gitnexus setup` copies them to `~/.cursor/skills/gitnexus/`. | +| **Hooks** _(this README)_ | `postToolUse` hook that enriches `Shell` / `Read` / `Grep` tool calls with graph context — same augmentation Claude Code gets | **Manual** — copy the two files described below into your project's `.cursor/`. | + +## Hook install + +Cursor 2.4+ reads `.cursor/hooks.json` from the project root and runs hook commands with the project root as the working directory ([docs](https://cursor.com/docs/agent/hooks)). + +From this repo's `gitnexus-cursor-integration/hooks/`, copy the two files into your **project root**: + +```text +/ +├── .cursor/ +│ └── hooks.json ← from gitnexus-cursor-integration/hooks/hooks.json +└── hooks/ + └── gitnexus-hook.cjs ← from gitnexus-cursor-integration/hooks/gitnexus-hook.cjs +``` + +Equivalent shell commands (run from your project root, with `$GITNEXUS_REPO` pointing at a clone of this repo): + +```bash +mkdir -p .cursor hooks +cp "$GITNEXUS_REPO/gitnexus-cursor-integration/hooks/hooks.json" .cursor/hooks.json +cp "$GITNEXUS_REPO/gitnexus-cursor-integration/hooks/gitnexus-hook.cjs" hooks/gitnexus-hook.cjs +``` + +If you already have a `.cursor/hooks.json`, merge the `hooks.postToolUse` array rather than overwriting. + +### Verify + +1.

Five call sites passed raw file content without any length guard: - captures.ts (C# scope extraction) - namespace-siblings.ts (extractFileStructure) - parse-worker.ts (worker thread parse path) - parsing-processor.ts (sequential parse fallback) Fix: truncate at the last newline before the limit so the fragment stays syntactically coherent. Files truncated mid-class produce ERROR roots; captures.ts returns [] for any ERROR-root tree so the legacy DAG handles the file silently without orphaned scope errors. Additional C# scope fixes: - scope-tree.ts: Module scopes may share the same range as a top-level namespace_declaration (files with no leading `using` directives). The rangeStrictlyContains check rejects equal ranges. Added rangeNonStrictlyContains for Module parents. - scope-extractor.ts: pass1BuildScopes stack-pop used strict containment; same Module == Namespace range case caused orphaned scopes. Added moduleAwareContains helper. - scope-extractor-bridge.ts: empty captures from ERROR-root files still called extractScope -> "no Module scope found" warning. Added early return for empty/non-array captures. - namespace-siblings.ts: three sites pushed onto binding arrays frozen by finalize-algorithm. Fixed with spread-copy before mutation. lbug-adapter.ts: INSTALL VECTOR in loadVectorExtension calls the KuzuDB native extension installer, which crashes with SIGSEGV on Windows via an unhandled error path in native code. JS try/catch cannot intercept native signals. Skip extension loading on win32 — vector/embedding search is unavailable on Windows but all graph index queries work correctly. Verified on: Windows 11, Node.js 24, gitnexus 1.6.3, pcf8-game codebase (61 757 nodes / 111 796 edges / 300 flows after fix). * fix(windows): skip FTS extension load in pool-adapter on Windows to prevent SIGSEGV LOAD EXTENSION fts crashes the process with SIGSEGV on Windows when the FTS extension binary is not installed locally. This is an @ladybugdb/core native bug — the extension loader hits an unhandled error path that raises a native signal instead of a JS exception, so try/catch cannot protect here. Add a process.platform === 'win32' guard in both doInitLbug and initLbugWithDb. When skipped, bm25-index.js catches the resulting Kuzu catalog errors (CREATE_FTS_INDEX not defined) and returns empty BM25 results gracefully. All graph queries (cypher, context, impact) are unaffected. This is patch 9 of the Windows fix series for gitnexus on Windows: patch 8 (same PR) already fixed INSTALL VECTOR SIGSEGV in lbug-adapter.ts. pool-adapter.ts is the separate MCP-server code path that was not covered. * fix: address codeql findings on PR #1433 The four `lastIndexOf('\n', ...)` calls were committed with a literal newline inside the single-quoted string instead of the `\n` escape, so the files do not parse — `tsc` and CodeQL both flagged them. Replace the embedded newline with `'\n'`. Also remove the two helpers that were superseded during review and became dead code: `rangeNonStrictlyContains` in scope-tree.ts (the equal-range carve-out is handled by `rangeStrictlyContains` + `rangesEqual` in `canParentScope`) and `moduleAwareContains` in scope-extractor.ts (`pass1BuildScopes` calls `canParentScope` directly). * fix(windows): replace 32767-char truncation with chunked-input parsing The tree-sitter 0.21.x Node binding crashes (SIGSEGV) on Windows when parser.parse(string, ...) is handed a JS string longer than 32 767 chars. The crash is in the bindings V8 string-to-buffer conversion and cannot be intercepted from JS. Previous mitigation truncated source at the last newline before that boundary, silently losing the file tail and producing ERROR-root trees from mid-class cuts. Switch to the callback (Parser.Input) overload via a new parseSourceSafe helper. tree-sitter pulls source in 16 KiB chunks via repeated callback invocations, bypassing the broken conversion path. Files are parsed in full, no data loss, no platform-specific code path. Removes the now-unnecessary ERROR-root short-circuit in csharp/captures.ts and the empty-captures shim in scope-extractor-bridge.ts; both existed only to swallow truncation-induced parse failures. * fix(windows): cover all parse sites and correct vector-extension state Address adversarial review on PR #1433: 1. Extend parseSourceSafe to all remaining parser.parse() call sites that handle full file content. The first commit only converted the four sites with active truncation hacks; cache-miss paths in call-processor (x2), heritage-processor (x2), import-processor, and the Go/Python/TypeScript captures + Go range-binding still called parser.parse() directly. On Windows those would still SIGSEGV for files > 32767 chars. 2. Stop setting vectorExtensionLoaded = true on the win32 short-circuit in lbug-adapter.ts. The flag means "successfully loaded" and is checked by an early-return at the top of loadVectorExtension; setting it on the skip path made the second call return true and let QUERY_VECTOR_INDEX run against a DB without the extension. 3. Drop the placeholder issues/... URL in the same comment. 4. Add unit tests for parseSourceSafe at boundary values: 16 KiB (direct/callback boundary), the 32 767 Windows crash boundary, single-line > chunk size, CRLF near boundary, and large all-Chinese source. Confirms the callback path is correct for non-ASCII content, which is also exercised by the existing csharp-captures large-file test. Researched the chunking concern: tree-sitter Node binding sets TSInputEncodingUTF16 and divides byte_index by 2 in ByteCountToJS before calling the JS callback, so the index argument is a UTF-16 code-unit offset — matching String.prototype.slice. Splitting tokens across chunks is safe by API contract; the lexer is chunk-agnostic. * fix(windows): extend parseSourceSafe to group/embeddings + lint enforcement Closes the remaining Windows SIGSEGV exposure flagged by the Codex adversarial review on PR #1433. Six pre-existing parser.parse(content) call sites bypassed parseSourceSafe and could crash the process on Windows when a contract IDL, route file, or embedding-target source exceeded 32 767 chars. Adds a lint rule so the regression vector closes permanently. Production code: - Relocate parseSourceSafe from ingestion/utils/ to core/tree-sitter/ so group/ and embeddings/ can import without crossing into ingestion internals. core/tree-sitter/ already houses parser-loader.ts and is the natural shared facade. All 11 existing importers updated; no shim left behind in the old location. - Route through parseSourceSafe in 5 group extractors (grpc, thrift, http-route, include, tree-sitter-scanner) and the embeddings ensureAndParse helper. - The seventh direct .parse() call in grpc-patterns/proto.ts:49 is a module-load grammar smoke test parsing a 36-char literal. Trivially safe by inspection, intentionally direct, filtered out by the lint rule via the string-literal-arg skip. Tests: - 5 caller-side regression tests with a vi.spyOn assertion on parseSourceSafe. The spy is what catches a regression: parser.parse on a 40 000-char input succeeds on Linux/macOS, so a "no throw" assertion alone would silently pass with the bypass reintroduced. - The vi.mock boilerplate is centralised in gitnexus/test/helpers/parse-source-safe-mock.ts, dynamic-imported inside each mock factory so vitest's hoister does not race the static import binding. Lint: - New custom ESLint rule gitnexus/require-safe-parse, scoped to gitnexus/src/core/**, fails on direct .parse(, ...) calls and auto-fixes them to parseSourceSafe(, ...). Skips JSON/URL/marked/Number/Math, string-literal first args (smoke tests), test files, and the helper itself. Auto-fix rewrites the call site only; the developer adds the import after tsc surfaces the missing identifier — same tradeoff as unused-imports/no-unused-imports. Plan: docs/plans/2026-05-10-001-fix-windows-parse-safety-group-and-embeddings-plan.md * fix(test): use mkdtempSync in http-route-extractor regression test Address CodeQL js/insecure-temporary-file warning on the new Windows- SIGSEGV regression test. The test was using path.join(tmpDir, "large-input") which, when nested inside a Date.now()-based parent tmpDir, lets CodeQL flag the directory as a predictable-name temp file with race-condition risk. Switch to fs.mkdtempSync(path.join(tmpDir, "large-input-")) so the suffix is a secure unique random string. --------- Co-authored-by: Gergő Magyar --- eslint-rules/require-safe-parse.mjs | 95 +++++++++++++++++++ eslint.config.mjs | 26 +++++ gitnexus/src/core/embeddings/ast-utils.ts | 3 +- .../core/group/extractors/grpc-extractor.ts | 3 +- .../group/extractors/http-route-extractor.ts | 3 +- .../group/extractors/include-extractor.ts | 3 +- .../core/group/extractors/thrift-extractor.ts | 3 +- .../group/extractors/tree-sitter-scanner.ts | 3 +- gitnexus/src/core/ingestion/call-processor.ts | 5 +- .../src/core/ingestion/heritage-processor.ts | 5 +- .../src/core/ingestion/import-processor.ts | 3 +- .../ingestion/languages/csharp/captures.ts | 3 +- .../languages/csharp/namespace-siblings.ts | 5 +- .../core/ingestion/languages/go/captures.ts | 3 +- .../ingestion/languages/go/range-binding.ts | 3 +- .../ingestion/languages/python/captures.ts | 3 +- .../languages/typescript/captures.ts | 3 +- .../src/core/ingestion/parsing-processor.ts | 5 +- .../core/ingestion/workers/parse-worker.ts | 3 +- gitnexus/src/core/lbug/lbug-adapter.ts | 7 ++ gitnexus/src/core/lbug/pool-adapter.ts | 19 +++- gitnexus/src/core/tree-sitter/safe-parse.ts | 40 ++++++++ .../test/helpers/parse-source-safe-mock.ts | 53 +++++++++++ gitnexus/test/unit/ast-utils.test.ts | 29 +++++- .../test/unit/group/grpc-extractor.test.ts | 36 ++++++- .../unit/group/http-route-extractor.test.ts | 40 +++++++- .../test/unit/group/include-extractor.test.ts | 41 +++++++- .../test/unit/group/thrift-extractor.test.ts | 43 ++++++++- gitnexus/test/unit/safe-parse.test.ts | 74 +++++++++++++++ 29 files changed, 533 insertions(+), 29 deletions(-) create mode 100644 eslint-rules/require-safe-parse.mjs create mode 100644 gitnexus/src/core/tree-sitter/safe-parse.ts create mode 100644 gitnexus/test/helpers/parse-source-safe-mock.ts create mode 100644 gitnexus/test/unit/safe-parse.test.ts diff --git a/eslint-rules/require-safe-parse.mjs b/eslint-rules/require-safe-parse.mjs new file mode 100644 index 000000000..4ab9dbd8a --- /dev/null +++ b/eslint-rules/require-safe-parse.mjs @@ -0,0 +1,95 @@ +/** + * Custom ESLint rule: require `parseSourceSafe(parser, content, ...)` instead + * of direct `.parse(, ...)` calls. + * + * Background: tree-sitter's Node.js native binding crashes with SIGSEGV on + * Windows when handed a JS string longer than 32 767 chars.

Threads caller filePath through pickUniqueGlobalCallable so static defs in other files are excluded. Finding 2: Documented single-invocation assumption on staticNames Map. Added clearStaticNames() call in loadResolutionConfig to prevent cross-repo contamination in server-mode scenarios. Finding 3: Added tree-sitter query pattern for function pointer typedef aliases (typedef void (*callback)(int, int)) in query.ts. Added unit test. Finding 4: Added c-static-isolation integration fixture (a.c with static helper, b.c with non-static helper, caller.c) and test asserting no CALLS edge from caller to a.c's static helper.

Distinguishes from explicit `int foo(void)`. 3 unit tests cover K&R definition, prototype, and void comparison. Finding 2: Added code comment documenting function-pointer-variable call capture as known architectural trade-off (same as Go resolver). Finding 3: Added code comment documenting prototype/definition duplication as graph-quality concern (no false CALLS edges). Finding 4: Renamed `_filePath` → `filePath` in captures.ts since it is actively used in markStaticName().

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(server): sanitize repo name to prevent argument injection Sanitizes the extracted repository name to prevent argument injection during git clone operations and ensures compatibility with various file systems. 1. Strips leading dashes to prevent git command-line argument injection. 2. Replaces unsafe directory characters with underscores. 3. Blocks path traversal segments ('.' and '..') and Windows reserved names. 4. Fixes ReDoS vulnerability in parseRepoNameFromUrl regex. 5. Added unit tests for sanitization and path traversal edge cases. * fix(server): expand Windows reserved name check to include extensions - Updated sanitizeRepoName to block Windows reserved names (CON, NUL, etc.) even when they have extensions (e.g., CON.txt). - Corrected regex and added unit tests for these edge cases to resolve CI failures on Windows. - Ref: https://github.com/abhigyanpatwari/GitNexus/pull/1305#issuecomment-4407200914 --------- Co-authored-by: Gergő Magyar --- gitnexus/src/server/git-clone.ts | 26 ++++++------ gitnexus/src/storage/git.ts | 63 ++++++++++++++++++++++------ gitnexus/test/unit/git-clone.test.ts | 40 ++++++++++++------ gitnexus/test/unit/git.test.ts | 59 ++++++++++++++++++++++++++ 4 files changed, 149 insertions(+), 39 deletions(-) diff --git a/gitnexus/src/server/git-clone.ts b/gitnexus/src/server/git-clone.ts index 861a16648..0ced1213a 100644 --- a/gitnexus/src/server/git-clone.ts +++ b/gitnexus/src/server/git-clone.ts @@ -11,6 +11,7 @@ import os from 'os'; import fs from 'fs/promises'; import { isIP } from 'net'; import { logger } from '../core/logger.js'; +import { parseRepoNameFromUrl } from '../storage/git.js'; /** Root directory for all cloned repositories.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(embeddings): forward GITNEXUS_EMBEDDING_DIMS as dimensions in HTTP request body When GITNEXUS_EMBEDDING_DIMS is set, include it as the `dimensions` field in the /v1/embeddings request body. This enables Matryoshka-capable models (OpenAI text-embedding-3-*, Cohere embed-v3, Voyage) to return truncated vectors at the requested size. When the env var is unset, the request body remains `{ input, model }` — no breaking change for backends that reject unknown fields. Adds 4 unit tests covering both paths (with/without dimensions) on both the batch embed and single-query embed code paths. * fix(embeddings): address review findings — strict parseInt, multi-batch test, comment wording 1. Strict parseInt validation: reject non-numeric strings like '1024abc' by checking /^\d+$/ before parseInt (Finding 1). 2. Add multi-batch test asserting dimensions is forwarded in every fetch call when inputs exceed batch size (Finding 2). 3. Soften JSDoc comment: backends may ignore or reject the dimensions field rather than universally ignoring it (Finding 3). 4. Add test for invalid GITNEXUS_EMBEDDING_DIMS values. --------- Co-authored-by: henry Co-authored-by: Gergő Magyar --- gitnexus/src/core/embeddings/http-client.ts | 42 +++++++- gitnexus/test/unit/http-embedder.test.ts | 112 ++++++++++++++++++++ 2 files changed, 149 insertions(+), 5 deletions(-) diff --git a/gitnexus/src/core/embeddings/http-client.ts b/gitnexus/src/core/embeddings/http-client.ts index e3fb06045..e8e9073ff 100644 --- a/gitnexus/src/core/embeddings/http-client.ts +++ b/gitnexus/src/core/embeddings/http-client.ts @@ -40,8 +40,11 @@ const readConfig = (): HttpConfig | null => { const rawDims = process.env.GITNEXUS_EMBEDDING_DIMS; let dimensions: number | undefined; if (rawDims !== undefined) { + if (!/^\d+$/.test(rawDims)) { + throw new Error(`GITNEXUS_EMBEDDING_DIMS must be a positive integer, got "${rawDims}"`); + } const parsed = parseInt(rawDims, 10); - if (Number.isNaN(parsed) || parsed <= 0) { + if (parsed <= 0) { throw new Error(`GITNEXUS_EMBEDDING_DIMS must be a positive integer, got "${rawDims}"`); } dimensions = parsed; @@ -91,7 +94,13 @@ interface EmbeddingItem { * @param model - Model name for the request body * @param apiKey - Bearer token (only used in Authorization header) * @param batchIndex - Logical batch number (for error context) - * @param attempt - Current retry attempt (internal) + * @param dimensions - Optional output-vector size.

This is problematic for bulk indexing operations on read-only mirrors or third-party repos. Add two new flags: - `--skip-skills`: suppress standard GitNexus skill file injection - `--index-only`: pure index mode that suppresses all file injection (AGENTS.md, CLAUDE.md, and skills), writing only to `.gitnexus/` This gives users three levels of control: - `--skip-agents-md` — suppress only root context files - `--skip-skills` — suppress only skill injection - `--index-only` — suppress everything (pure indexing) Discovery context: while bulk-indexing 176 repos with `--skip-agents-md`, all 144 indexed repos were contaminated with `.claude/skills/gitnexus/` files requiring manual cleanup. * fix(cli): address PR #742 review — gate community skills, drop dangling refs, add tests Bot review (#742) flagged three issues with the original commit: 1. `--index-only --skills` still wrote community-derived skill files to `.claude/skills/generated/`. The `--skills` branch in analyze.ts was not gated by `skipAll`, so the "skip all file injection" contract was violated. Gate `generateSkillFiles()` with `!skipAll` so `--index-only` truly wins over `--skills`. 2. `--skip-skills` without `--skip-agents-md` produced AGENTS.md / CLAUDE.md that still referenced `.claude/skills/gitnexus/*/SKILL.md` files that were never installed — every agent load incurred 6 failed reads. Pass `skipSkills` through to `generateGitNexusContent()` and omit the standard-skill rows (and the entire `## CLI` heading when the table is empty). Community skills, when present via `--skills`, are unaffected. 3. No filesystem tests for `skipSkills` / `indexOnly`. Add three regression guards to `test/unit/ai-context.test.ts`: - `.claude/skills/gitnexus/` is NOT created when skipSkills=true - Nothing is written when both skipAgentsMd and skipSkills are true (the resolved-flag state from --index-only) - AGENTS.md/CLAUDE.md routing table omits standard skill references when skipSkills=true, but preserves the load-bearing imperative sections (Always Do / Never Do / Resources) * test(cli): PR 1485 review follow-ups (help text, gate test, --skip-skills docs) - Assert --skip-skills and --index-only in analyze --help (skip-git-cli.test.ts). - Export shouldGenerateCommunitySkillFiles; unit-test index-only+skills gate. - Clarify --skip-skills does not suppress --skills community files; --index-only for full skip. Co-authored-by: Cursor * fix(cli): warn when --index-only silently overrides --skills Address review findings on PR 1485 follow-ups: - analyze.ts emits a one-line note when both --index-only and --skills are set, so users see why a pipeline re-index ran with no skill files written. - index.ts --skills help text now flags the --index-only override. - shouldGenerateCommunitySkillFiles JSDoc documents the dual role of the gate (community skills + AGENTS.md/CLAUDE.md re-generation). - skip-git-cli.test.ts pins the override-warning surface end-to-end. --------- Co-authored-by: Gergő Magyar Co-authored-by: Cursor --- gitnexus/src/cli/ai-context.ts | 43 +++++++-- gitnexus/src/cli/analyze.ts | 48 +++++++++- gitnexus/src/cli/index.ts | 13 ++- gitnexus/src/core/run-analyze.ts | 8 +- gitnexus/test/unit/ai-context.test.ts | 95 +++++++++++++++++++ .../analyze-community-skills-gate.test.ts | 27 ++++++ gitnexus/test/unit/skip-git-cli.test.ts | 32 +++++++ 7 files changed, 250 insertions(+), 16 deletions(-) create mode 100644 gitnexus/test/unit/analyze-community-skills-gate.test.ts diff --git a/gitnexus/src/cli/ai-context.ts b/gitnexus/src/cli/ai-context.ts index 41ba6c73e..8e18fed7d 100644 --- a/gitnexus/src/cli/ai-context.ts +++ b/gitnexus/src/cli/ai-context.ts @@ -28,6 +28,7 @@ interface RepoStats { export interface AIContextOptions { skipAgentsMd?: boolean; noStats?: boolean; + skipSkills?: boolean; } const GITNEXUS_START_MARKER = ''; @@ -94,6 +95,7 @@ function generateGitNexusContent( generatedSkills?: GeneratedSkillInfo[], groupNames?: string[], noStats?: boolean, + skipSkills?: boolean, ): string { const generatedRows = generatedSkills && generatedSkills.length > 0 @@ -105,14 +107,26 @@ function generateGitNexusContent( .join('\n') : ''; - const skillsTable = `| Task | Read this skill file | -|------|---------------------| -| Understand architecture / "How does X work?" | \`.claude/skills/gitnexus/gitnexus-exploring/SKILL.md\` | + // Standard skill rows reference files installed by installSkills().

FTS indexes cannot be created in read-only mode, so searchFTSFromLbug returns ftsAvailable=false and an empty results array. The existing early-return path silently produced no enrichment. Add a Cypher name CONTAINS fallback that fires only when ftsAvailable is false and BM25 produced no symbol matches. This covers the read-only DB case (concurrent MCP server) and the first-run case (indexes not yet built). The fallback is wrapped in .catch(() => []) and cannot throw. When FTS indexes exist, this branch is never reached — behaviour is unchanged for users without a concurrent MCP server. * fix(augment): guard against CONTAINS '' and add no-FTS test coverage Blocker 1 — CONTAINS '' on whitespace-leading patterns: pattern.split(/\s+/)[0] returns "" when the input has leading whitespace (e.g. " ".split(/\s+/) → ["", ""]). In Kuzu, CONTAINS '' matches every node with a name property, injecting arbitrary graph nodes into LLM context. Fix: trim() before split, then guard on !firstWord || firstWord.length < 2. No behaviour change for normal non-empty patterns. Blocker 2 — zero test coverage on the FTS-unavailable code path: The new CONTAINS fallback block (engine.ts lines 146-166) was exercised by no existing test — all existing tests run with FTS indexes built. A second withTestLbugDB fixture is added with no ftsIndexes, forcing searchFTSFromLbug to return ftsAvailable: false, and asserts: 1. augment('login', ...) returns non-empty enrichment (fallback works) 2. augment(' ', ...) returns '' (CONTAINS '' guard holds) 3. augment('nxyz_notfound', ...) returns '' (no matching nodes) 4. executeQuery throwing returns '' (.catch(() => []) path) * fix(augment): extend CONTAINS '' guard to FTS happy path and consolidate The same split(/\s+/)[0] bug existed at line 125 (BM25 symbol filter, FTS-available path) — a leading-whitespace pattern produced CONTAINS '' there too, matching every node in BM25-matched files. Fix: hoist patternFirstWord computation with trim() and the length guard to the top of augment(), before any DB interaction. Both CONTAINS sites (BM25 symbol filter and CONTAINS fallback) now use the single pre-validated value. No behaviour change for normal patterns; the guard fires once for all callers instead of being duplicated. Also tighten the whitespace test in the no-FTS suite from 3 spaces to 4 spaces so it unambiguously exercises the patternFirstWord guard rather than straddling the outer pattern.length < 3 boundary. * test(augment): negative-safety test for ftsAvailable=true gate Asserts the CONTAINS fallback does NOT fire when FTS is available but BM25 returns zero results. Pins the safety property promised by the PR description: behavior is unchanged for users without the read-only-DB condition.

Co-Authored-By: Claude Opus 4.7 (1M context) * feat(communities): seed Leiden RNG for deterministic community detection The vendored Leiden algorithm defaults to Math.random for tie-breaking and randomized walks, which produces non-deterministic community assignments and modularity values across runs on the same graph. Pass a seeded mulberry32 RNG (LEIDEN_SEED=0xC0DE) so: - The same graph always produces the same partition - Modularity values are reproducible - Equivalence tests for incremental indexing can compare community assignments byte-for-byte This is foundational for the upcoming incremental-indexing feature (see docs/superpowers/specs/2026-05-10-incremental-indexing-design.md) where the correctness contract is incremental output ≡ full rebuild output. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(incremental): change-detection, surface signatures, closure expansion Three new modules supporting the incremental-indexing pipeline: * core/incremental/git-diff.ts — getChangedFilesSinceCommit() unions 'git diff lastCommit HEAD' (committed) with 'git status --porcelain' (dirty tree). Renames flattened to delete(orig) + add(new). Throws LastCommitMissingError when lastCommit is gone (caller falls back to full rebuild). * core/incremental/surface.ts — extractSurfaceSignature() produces a stable hash of a file's publicly-visible symbols (functions, classes, methods, interfaces, types, heritage). Body-only edits → same hash. Signature/heritage changes → different hash. Drives the closure scoping optimization. * core/incremental/closure.ts — computeImporterClosure() iterative fixpoint: parse each closure file, extract surface, query DB importers, expand. Uses a parseCache so each file is parsed once. Generic over TParseResult so closure logic is decoupled from the pipeline's parse representation. 32 unit tests across the three modules. Tests cover edge cases: clean tree, dirty-only, mixed, renames, deletes, multi-hop cascade, cycle termination, surface invariance, etc. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(lbug): loadGraphFromLbug, queryImporters, deleteAllCommunitiesAndProcesses Three new primitives in lbug-adapter.ts to support incremental indexing: * loadGraphFromLbug(graph, unchangedFilePaths) — streams all nodes for files in the set across every hydratable node table (excludes Community/Process — graph-wide, regenerated downstream). Then loads edges where both endpoints belong to loaded nodes, excluding MEMBER_OF / STEP_IN_PROCESS edges (also graph-wide). FilePaths chunked at 200 per query to keep statement size bounded on huge repos. Endpoint-level join filters by source-side filePath in the query, target-side checked JS-side via the loadedNodeIds set. * queryImporters(targetFilePath) — returns DISTINCT a.filePath where a -[IMPORTS]-> b and b.filePath = target. Powers closure expansion: when a changed file's surface signature changes, all its importers must be re-parsed. * deleteAllCommunitiesAndProcesses() — drops Community/Process nodes (and their edges via DETACH DELETE) at the start of each incremental run so the communities/processes phases regenerate them from the fully-merged graph. Required for the 'Leiden runs on full graph' correctness invariant. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(pipeline): hydrate phase + parse-filter for incremental indexing Wires the incremental-indexing infrastructure into the phase-based pipeline. Three coordinated changes: * New hydratePhase (deps: structure) — loads node/edge state for files OUTSIDE ctx.options.filesToParse from the existing LadybugDB index. Runs before parse so the parse phase can produce a partial graph while downstream phases (mro, communities, processes) still see the full graph. No-op in full-rebuild mode (filesToParse unset). * PipelineOptions.filesToParse: optional ReadonlySet. When set, parse phase filters scanned files to this set; hydrate fills the complement. Set by runFullAnalysis when it detects an eligible incremental run; never set by callers directly. * gitnexus-shared PipelinePhase enum: 'hydrate' added so progress callbacks can report the new phase distinctly from 'structure'. Phase order: scan → structure → hydrate → markdown,cobol → parse → routes,tools,orm → crossFile → scopeResolution → mro → communities → processes. Communities (Leiden) still runs on the full graph, satisfying the correctness invariant. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(analyze): incremental orchestrator branch + meta schema Wires incremental indexing into runFullAnalysis. Highlights: * RepoMeta schema extended: schemaVersion, surfaceSignatures, and incrementalInProgress fields. INCREMENTAL_SCHEMA_VERSION = 1. * core/incremental/file-hash.ts — v1 surface signature: SHA-256 of file content. v2 will switch to a true surface-only signature (defined in surface.ts) so body-only edits don't expand the closure. The plumbing is signature-agnostic so the swap is local. * core/incremental/orchestrator.ts — eligibility check, closure computation (uses file-hash as the surface signal), dirty-flag management, subgraph extraction, signature merge. * run-analyze.ts adds: - hasDirtyTree() check on the existing 'lastCommit==HEAD' early-exit so an uncommitted edit triggers re-index (was a coarse equality check before). - incremental branch: try incremental first; fall through to full rebuild on any setup failure or eligibility miss. - runIncrementalBranch() — opens existing DB, deletes closure-file rows + Community/Process, runs pipeline with filesToParse, writes only the changed-subgraph back, refreshes FTS, updates meta with new surfaceSignatures and clears the dirty flag. - Full-rebuild path now populates surfaceSignatures + schemaVersion in meta.json so the next run is eligible for incremental. Crash recovery: incrementalInProgress is set BEFORE any DB mutation and cleared on success by overwriting meta.json. A crash anywhere in between leaves the flag set, and the next analyze run forces a full rebuild (cheapest path back to a known-good index). v1 limitation documented: body-only edits trigger 1-hop closure expansion (content-hash signal). True surface-only optimization is deferred to v2 — see design doc for the integration path. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): drop invalid --no-renames=false from git diff The flag --no-renames=false isn't valid git syntax (it's parsed as a file path). Git's default rename detection is on; removing the flag keeps that behavior. Caught while running an end-to-end smoke test against a small fixture repo: incremental setup failed with 'Command failed: git diff --name-status -z --no-renames=false ...'. After the fix, the incremental path runs cleanly: closure is computed, hydrate phase loads unchanged-file state from DB, parse phase only re-parses files in closure, and the writeback updates only changed nodes/edges. Co-Authored-By: Claude Opus 4.7 (1M context) * Revert v1 incremental indexing (5 commits) Reverts the v1 design that parsed only closure files into a fresh graph and tried to hydrate the rest from DB. Real-repo equivalence test failed: cross-file resolution operates on partial parse data (closure files only), so CALLS edges that resolve through unchanged files silently fall off. Diff against full rebuild on the same edited state: -50 nodes, -425 edges, -5 communities, -48 processes. Architecture pivot: switch to PR #533-style content-addressed parse cache. Pipeline parses every file (cache-served when possible), giving cross-file resolution full data, with DB writeback then restricted to changed-file rows.

The pipeline still parses every file (correctness invariant: cross-file resolution / scope resolution / MRO / community detection all need full graph data); the saving comes from selectively replacing only changed-file rows in LadybugDB instead of wiping and reloading the whole graph. How it works: * On every analyze, we hash all source files (SHA-256 of content) and store the map in meta.json.fileHashes alongside schemaVersion. * The next run loads the prior map and diffs: - changed: content hash differs → file's DB rows replaced. - added: not in prior map → file's DB rows inserted. - deleted: in prior map but not on disk → file's DB rows dropped. * If the diff is non-empty AND no --force / no schema mismatch / no dirty flag, take the incremental path: - Set incrementalInProgress dirty flag (BEFORE any DB mutation). - Open existing DB (no wipe). - deleteNodesForFile() for each changed/added/deleted file. - deleteAllCommunitiesAndProcesses() — Leiden regenerates these. - extractChangedSubgraph() from the in-memory ctx.graph: nodes whose filePath is in the writable set + Community + Process + edges with at least one endpoint in the writable set (edges entirely between hydrated unchanged nodes are skipped — already in DB). - loadGraphToLbug() on the subgraph. Unchanged-file rows in DB untouched. - Recreate FTS indexes. - Update meta with new fileHashes; clear dirty flag. * Otherwise full-rebuild path runs as before. Crash recovery: incrementalInProgress is the dirty flag. Set before destructive ops; cleared on success. Set on next-run startup → forces full rebuild (cheapest path back to known-good). Other changes: * Dirty-tree gate on the existing 'lastCommit==HEAD' early-return: uncommitted edits no longer slip through as 'already up to date'. * deleteAllCommunitiesAndProcesses helper in lbug-adapter. * Skip the embedding cache+restore cycle when willTryIncremental is true — embeddings stay in DB; re-inserting them would PK-conflict. End-to-end equivalence verified on this repo (993 files, 24K nodes): incremental run produces byte-identical {nodes, edges, clusters, flows} to a full rebuild from the same edited state. Speedup is currently modest (~5% on this repo) because the parse phase still runs in full. Parse-cache integration is a separate follow-up that composes cleanly on top of this work. See docs/superpowers/specs/2026-05-10-incremental-indexing-design.md. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(analyze): chunk-level parse cache for full incremental speedup Composes with the incremental DB writeback (commit 27f3b49d) to deliver the major-speedup half of incremental indexing. Previously, the parse phase ran in full on every analyze; the speedup came purely from selective DB rewriting. With this commit the parse phase also reuses prior tree-sitter output for chunks whose contents haven't changed. How it works: * Cache layer (gitnexus/src/storage/parse-cache.ts): - File: /.gitnexus/parse-cache.json. Versioned, atomic write. - Key: chunk content hash = sha256(sorted(filePath:fileContentHash for each file in chunk)). - Value: ParseWorkerResult[] (raw worker output for the chunk, pre-merge). - Granularity: per chunk (~20MB byte-budget). A change to one file invalidates only its chunk — typically 1 of ~50 on a 1000-file repo (~98% cache hit ratio on a small edit). * Worker contract (gitnexus/src/core/ingestion/parsing-processor.ts): - Extracted the chunk-result merge loop into a public mergeChunkResults() so the same logic applies to live worker output AND replayed cache entries. - processParsingWithWorkers / processParsing accept an optional outRawResults out-parameter that captures worker output before merging — used by parse-impl to populate the cache after a miss. * Parse phase wiring (parse-impl.ts): - For each chunk, compute its content hash (after reading file contents). Cache hit → mergeChunkResults() on cached results, skip the worker dispatch entirely. Cache miss → run workers normally, capture raw results, store under the chunk hash. - Cache mutations happen in-place on the ParseCache passed via PipelineOptions.parseCache. * Lifecycle (run-analyze.ts): - loadParseCache() before pipeline runs. - Cache passed via runPipelineFromRepo's PipelineOptions. - saveParseCache() after the pipeline + DB writeback succeed. Equivalence verified on this repo (993 files, 24K nodes): Cold (no cache, full work): 141.1s Warm cache + 1-file edit, incremental: 63.6s ← 55% speedup Warm cache + 1-file edit, --force: 71.6s ← 49% speedup All three runs produce byte-identical {nodes, edges, clusters, flows}. The cache survives --force (content-addressed = always correct), so even forced rebuilds get the parse-skip benefit. Why chunk-level rather than per-file: workers process sub-batches and emit aggregated ParseWorkerResults. Per-file granularity would require restructuring the worker contract; chunk-level captures most of the practical speedup with no worker-side changes. Co-Authored-By: Claude Opus 4.7 (1M context) * perf(parse-impl): smaller default chunk budget (20MB→2MB) for cache granularity The parse cache is keyed at chunk granularity. With the previous 20MB budget, a typical mid-size repo (e.g. this worktree at 9MB total parseable source) fits in a single chunk — meaning ANY file change invalidates the whole chunk and re-parses every file. 2MB default produces ~5x more chunks on the same input, so a one-file edit invalidates ~1/N of cached chunks instead of the whole thing. Cold-run overhead from more chunks is <5% (one extra serialization pass per chunk). Override via GITNEXUS_CHUNK_BYTE_BUDGET env var for benchmarking. Measured on this repo (~9MB / 887 parseable files): Cold (no cache): 143s Warm cache, no source changes: 2s (early-return) Warm cache + 1-file edit: 81s (~43% off cold) Speedup is bounded by the scopeResolution phase (~58s flat regardless of parse cache) and by GitNexus's own auto-writes during analyze (AGENTS.md / .claude/skills/ etc. mutate between runs and invalidate chunks containing them). Both are addressable in follow-ups. Co-Authored-By: Claude Opus 4.7 (1M context) * perf(scope-resolution): reuse worker-produced ParsedFile + stabilize chunk order Two compounding optimizations that drop warm-cache analyze from ~134s to ~38s on a 1000-file repo (72% faster), and cold rebuild from ~143s to ~86s (40% faster) by short-circuiting work that was previously re-done. 1. SCOPE-RESOLUTION: REUSE WORKER PARSEDFILE Previously, the scope-resolution phase re-parsed every file with tree-sitter on the main thread (~58s on a 1000-file repo) because worker-produced tree-sitter Trees can't cross the worker MessageChannel. But the worker ALSO produces a artifact via , which structured-clones fine — and it's exactly what scope-resolution would re-derive. Threading those ParsedFiles through the parse phase () into ( map) lets scope- resolution skip its extract loop on a per-file basis. The fast path is bounded only by per file (cheap graph mutation). On this repo: scopeResolution went from 58s → 5s. 2. MAP-PRESERVING PARSE-CACHE SERIALIZATION is a which JSON.stringify collapses to . The first attempt at threading parsedFiles through the parse cache crashed at runtime with "importerModule.typeBindings is not iterable" because cached entries came back as plain objects. Added a JSON replacer/reviver pair in parse-cache.ts that round-trips Map and Set instances through tagged plain objects (). Symmetric: save uses replacer, load uses reviver. 3. STABLE CHUNK ORDERING The byte-budget chunker walked files in filesystem-scan order, which on Windows isn't guaranteed to be stable across runs. Even with identical source content, two scans could place files in different chunks, shifting chunk hashes and causing 100% parse-cache misses. Added a deterministic alphabetical sort on before chunking. Chunk membership is now stable across runs, so a single-file edit invalidates exactly one chunk, not all of them. Measured on this repo (993 files, 24K nodes): Cold rebuild: 86s (was 143s) Warm cache, no source changes: 3s (early-return) Warm cache + 1-file edit: 38s (was 134s) Co-Authored-By: Claude Opus 4.7 (1M context) * docs(incremental): update spec + AGENTS.md + GUARDRAILS.md for shipped design - Rewrite docs/superpowers/specs/2026-05-10-incremental-indexing-design.md to describe the architecture that actually shipped (parse cache + incremental DB writeback + scope-resolution short-circuit), with the v1 hydrate-phase post-mortem preserved as historical context. - AGENTS.md "Keeping the Index Fresh" section: note that incremental is the new default and --force is the explicit opt-out; mention the parse-cache file location and that it's safe to delete. - GUARDRAILS.md Signs: add an "Index seems corrupt or incremental is misbehaving" entry pointing users to --force as the manual escape hatch (the dirty flag handles automatic recovery). Co-Authored-By: Claude Opus 4.7 (1M context) * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(incremental): bugbot review + CI test failures Bugbot (PR #1479): - Medium: pruneCache was exported but never called -> cache grew unbounded. Wire pruneCache into run-analyze before saveParseCache, using a transient usedKeys Set on ParseCache that the parse phase populates as it processes chunks. - Low: willTryIncremental (pre-pipeline) and isIncremental (post-pipeline) could desync, silently dropping embeddings on mispredicted runs. Removed the prediction; the embedding cache now loads unconditionally when shouldLoadCache is true. The re-insert step gates on the actual isIncremental value to avoid PK-conflicts when the incremental-writeback path keeps DB rows. CI test failures: - cli-e2e #1169 + run-analyze.test.ts #1233: my dirty-tree gate on the lastCommit==HEAD early-return saw GitNexus's own auto-generated outputs (.claude/, .cursor/, AGENTS.md, CLAUDE.md) as dirty, perpetually defeating the up-to-date fast path. Extended the pathspec exclusion to cover all auto-gen outputs, not just .gitnexus/. - ruby field-type disambig: my chunk-stability sort exposed a pre-existing order-dependency in Ruby cross-file resolution (`user.address.save -> Address#save` only resolves correctly when user.rb parses before address.rb in some configurations). Removed the sort. Filesystem ordering is stable enough in practice that the parse cache still hits the common case; the pre-existing fragility is left for a separate fix. - pipeline-graph-golden: regenerated. Seeded Leiden RNG produces a partition different from the previous Math.random snapshot. - staleness `parallel calls` was a CI timing flake; passes locally. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): re-insert cached embeddings on incremental path Bugbot re-review caught: deleteNodesForFile cascades to the CodeEmbedding table (DELETE WHERE e.nodeId STARTS WITH ...), so changed-file embedding rows are wiped along with their nodes. The previous fix gated re-insert on `!isIncremental`, which silently dropped those embeddings — a regression versus the full-rebuild path's "preserve embeddings by default" guarantee. Remove the `!isIncremental` gate. The per-batch try/catch already handles the unchanged-file PK-conflict case ("some may fail if node was removed, that's fine") with the same semantics, so re-inserting the full cached set on incremental works: - changed-file rows: deleted, then re-inserted from cache (preserved) - unchanged-file rows: still in DB, re-insert PK-conflicts and is silently ignored (existing rows are correct) Cost: re-inserting ~24K embeddings on incremental when only a few files changed — most are no-op conflicts. Bounded by batch size of 200; ~3-5s overhead. Worth it for correctness. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): address Claude+Bugbot review findings + remove design doc Addresses CHANGES_REQUESTED review on PR #1479: 1. Remove docs/superpowers/specs/2026-05-10-incremental-indexing-design.md per maintainer request. 2. BLOCKER (Claude Finding 1, Bugbot Round 3): Stale cross-file edges between unchanged files. extractChangedSubgraph excluded edges where both endpoints were unchanged-file nodes — when a barrel/re-export file changes, cross-file resolution may update CALLS edges between two unchanged files that would then be silently lost. Fix: 1-hop importer-closure expansion of the writable set in run-analyze.ts. Before deleting/rewriting rows, query DB for importers of every changed/deleted file and add them to the writable set. Their nodes get deleted+rewritten too, so cross-file's refined edges land in the DB. Re-added queryImporters to lbug-adapter.ts. 3. BLOCKER (Claude Finding 3): Parse cache key omitted parser version. After a GitNexus upgrade, the cache silently replays pre-upgrade ParseWorkerResults against the new schema → wrong CALLS/IMPORTS/ scope edges with no visible signal. Fix: PARSE_CACHE_VERSION now embeds the gitnexus npm package version (read at module load via createRequire on package.json). Format: `${SCHEMA_BUMP}+${PKG_VERSION}` e.g. "1+1.6.4". Any release that bumps package.json automatically invalidates the on-disk cache. Mismatched versions fall through to an empty cache (next save overwrites with the new version baked in). 4. BLOCKER (Claude Finding 2): No automated tests for incremental behavior. Added 28 unit tests across 3 files: - incremental-file-hash.test.ts (10 tests) diffFileHashes classification, computeFileHash determinism, computeFileHashes batch / missing-file tolerance, sorted output. - incremental-parse-cache.test.ts (12 tests) computeChunkHash stability and order-independence, version prefix format, pruneCache, load/save round-trip on empty / missing / corrupt / version-mismatched files, AND a Map/Set round-trip test that pins the JSON replacer/reviver behaviour (without it, ParsedFile.scopes[*].typeBindings collapses to {} and downstream `.get()` / iteration throws). - incremental-subgraph-extract.test.ts (6 tests) writable-set node inclusion, Community/Process always kept, edge inclusion when at least one endpoint is writable, MEMBER_OF edges via graph-wide endpoints, empty subgraph case. 5. Medium (Claude Finding 6): AGENTS.md "Keeping the Index Fresh" said "only changed files are re-parsed." Imprecise — the pipeline parses every file every run; the cache skips tree-sitter for chunks whose contents haven't changed. Reworded to match the design doc. Test plan still expects: [x] Typecheck clean [x] All 28 new unit tests pass [x] All previously-failing tests still pass on the rebased branch [x] Equivalence verified locally (incremental ≡ --force, byte-identical stats on this repo) Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): round 3 review feedback — bounded BFS, atomic meta, integration test, docs Addresses remaining findings on PR #1479 from Claude's re-review of commit ad7bd31 + verifies the outstanding Bugbot HIGH severity. 1. F1 — Transitive importer expansion (Claude, was Medium-but-noted). Previous 1-hop importer expansion missed barrel re-export chains (A imports C, C re-exports B; when B changes, only C was pulled in — A was left with potentially-stale CALLS edges to refined targets). Replaced the single pass with a bounded BFS over the IMPORTS graph (depth ≤ 4). Catches nested barrel pyramids without ballooning into a near-full rebuild on monorepos with deep re-export trees. `--force` remains the escape hatch documented in GUARDRAILS.md for cases that exceed the bound. 2. F2 — Integration test for incremental orchestration (Claude, BLOCKER, DoD §2.7). The unit tests added in ad7bd31 covered `diffFileHashes`, `extractChangedSubgraph`, `computeChunkHash`, `pruneCache`, and the Map/Set JSON round-trip — but none of them exercised the real `runFullAnalysis` orchestration. Added gitnexus/test/unit/ incremental-orchestration.test.ts with four end-to-end tests against a real git-initialized fixture repo + real LadybugDB: a. First run populates fileHashes + schemaVersion and clears incrementalInProgress on success. b. Second run on unchanged state takes the alreadyUpToDate fast path (early-return). c. Second run after a source edit takes the incremental path (not full rebuild) and rotates fileHashes for the touched file while keeping the dirty flag cleared. d. A pre-set incrementalInProgress flag forces a full rebuild that clears it (crash-recovery wire). These would catch any regression that wires `isIncremental` from a pre-pipeline prediction (the Bugbot finding from commit 5eb0597) or accidentally re-gates the embedding re-insert on `!isIncremental` (the Bugbot finding from commit 60c10f1). 3. F3 — GUARDRAILS.md docs accuracy (Claude, Low). Line 33 still said "only changed files are re-parsed" — AGENTS.md was already corrected in ad7bd31 but GUARDRAILS.md was missed. Reworded to match. 4. F5 — Atomic saveMeta (Claude, Medium; vvladescu-tb fork). The dirty flag (`incrementalInProgress`) travels through meta.json. A crash mid-write would leave a corrupt meta.json that `loadMeta` would silently treat as "no prior index", losing the flag and skipping recovery. Switched to tmp-file + rename matching saveParseCache. 5. Bugbot's "Subgraph edges reference nodes absent from subgraph" (HIGH severity). Verified as FALSE POSITIVE: `getNodeLabel` in lbug-adapter.ts derives labels from the node-ID string (parses the table prefix), not from the in-memory graph. The CSV generator writes (src_id, dst_id, type) rows without consulting node objects; `splitRelCsvByLabelPair` routes by ID-derived label; `COPY ... (from=X, to=Y)` resolves both endpoints against the live LadybugDB where unchanged-file nodes still exist. No fix needed. All 213 tests pass locally (including the 4 new integration tests and the previously-failing CI tests). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): address Bugbot round-4 findings (added-file shadow seed + dedupe) Bugbot review on commit e23e4400 surfaced two new findings against the incremental writeback in run-analyze.ts: HIGH — Incremental BFS misses importers of newly added files. queryImporters() reads the pre-pipeline DB. For a NEWLY ADDED file there are no IMPORTS rows pointing to it yet, so unchanged files whose pre-existing import statements now resolve to the newcomer keep stale CALLS edges pointing at the OLD resolution target. LOW — Deleted files double-counted in filesToDelete. hashDiff.deleted entries can reappear in writableFiles via the BFS expansion (queryImporters can return a now-deleted path), so deleteNodesForFile() ran twice for the same file. Fixes: - Add gitnexus/src/core/incremental/shadow-candidates.ts: derive the pre-existing file paths whose JS/TS module-resolution claim an added file can steal. Pattern catalogue: same-basename/ different-extension, bare-file-beats-directory-index, and directory-index-beats-bare-file. Emit both POSIX and Windows separators because the prior fileHashes map may have been written from either OS. - In run-analyze.ts, seed the BFS frontier with shadow candidates that exist in the prior meta.fileHashes. Their importers — found via queryImporters — get pulled into the writable set so their CALLS edges re-resolve against the new file. - Dedupe filesToDelete via Set to avoid the double-call. Tests: gitnexus/test/unit/incremental-shadow-candidates.test.ts — 8 cases covering each shadow pattern, separator handling, .d.ts as a single extension token, deduplication, and the no-self-shadow invariant. All 40 incremental tests (file-hash, parse-cache, subgraph-extract, shadow-candidates, orchestration) pass locally. Note on the third Bugbot finding ("Subgraph edges reference nodes absent from subgraph"): re-anchored from a prior review pass — the code at subgraph-extract.ts:48 is unchanged. Already verified as a false positive: getNodeLabel parses labels from ID strings, CSV write is by ID, and COPY resolves against the live DB. * chore(autofix): apply prettier + eslint fixes via /autofix command * test(incremental): exact-equality stats invariant + analyze ≡ analyze --force Addresses the only remaining Claude production-readiness review finding on PR #1479 (Low-Medium, test-quality only — Claude itself said it does NOT block merge, but the central PR claim "incremental ≡ full rebuild" deserves explicit CI coverage rather than implicit trust). Changes to gitnexus/test/unit/incremental-orchestration.test.ts: 1) Tighten the existing "comment-only edit takes incremental path" test. - Replace toBeGreaterThan(0) bounds assertions on stats.files and stats.nodes with exact toBe(firstMeta) per-field equality across files / nodes / edges / communities / processes. DoD §2.7 calls out bounds-only assertions as masking regressions that drop half the graph; this swap closes that gap. - Rationale: a comment-only edit must change the file content hash (driving the incremental path) without changing any graph data. Therefore every stat MUST be identical to the first run. Anything else is a regression. 2) New test: incremental output is byte-equivalent to a full rebuild. - Run analyze → comment-only edit → analyze (incremental writeback) → analyze --force (full rebuild from same on-disk state). - Assert files / nodes / edges / communities / processes are exactly equal across the incremental and the --force passes. - This is the PR's central correctness contract, now proven by a test that exercises the real runtime path end-to-end against a real on-disk LadybugDB. All 5 orchestration tests pass locally (52s), including the new equivalence test — every stat field matches exactly between incremental and --force on the mini-repo fixture. tsc --noEmit clean. * fix(incremental): F1 cross-file edge consistency + F4 stable chunk sort + unit coverage (#1511) Patch addressing two of the still-open changes-requested findings on PR #1479, rebased onto the current feat/incremental-indexing head. F3 (parser fingerprint in the cache key), F5 (atomic saveMeta), and F6 (AGENTS.md phrasing) were already handled on the branch, so the corresponding parts of the original patch were dropped as redundant. F1 (Blocker) — Cross-file edges between unchanged files Adds `computeEffectiveWriteSet(graph, toWriteSet)` to subgraph-extract.ts: a single pass over the new graph's edges that pulls the unchanged-side file of every writable-boundary-crossing edge into the write set. run-analyze composes it ON TOP of the existing importer-BFS expansion and feeds the combined set to BOTH `deleteNodesForFile` and `extractChangedSubgraph`, so the delete cascade and the writeback subgraph cover identical files (asymmetry would leave stale rows or PK-conflict at COPY time). The BFS reads IMPORTS from the pre-pipeline DB (catches files that *stopped* importing a changed file); the edge walk reads the new graph (catches refined CALLS edges the pre-run DB couldn't predict, e.g. a barrel re-export shifting a symbol from B to D). `extractChangedSubgraph` stays a pure filter — all expansion is the orchestrator's job. F4 (Medium) — Restore alphabetical chunk sort `parseableScanned` is sorted before chunking. Filesystem-scan order isn't stable enough across runs/platforms (notably macOS APFS) to keep chunk hashes consistent, so the parse cache thrashes without it. The pre-existing Ruby cross-file resolution order-dependency the old comment cited is independent — the sort surfaces it but doesn't cause it; tracked separately rather than leaving the cache cold. Tests — incremental-subgraph-extract.test.ts Locks the F1 invariants: `extractChangedSubgraph` is a pure filter (includes only the set it's given, plus graph-wide nodes; edges fire on one writable endpoint), and `computeEffectiveWriteSet` covers the barrel-re-export scenario, the symmetric edge-into- changed-file case, the no-boundary-crossed no-op, graph-wide-node edges, and input-immutability. Supersedes the prior extractChangedSubgraph-only test file on the branch.

That left the sequential and worker paths emitting non-identical Property nodes/symbols for the same source — silently breaking the `incremental ≡ --force` invariant the moment a repo crosses the worker threshold between runs. Two concrete divergences are closed here: * Node id: worker keys Property as `${file}:${className}.${propName}` (qualified). Pre-pass was using `${file}:${propName}` (unqualified). Same source produced different graph ids depending on which path ran. * Field metadata: worker enriches each routed property with `provider.fieldExtractor` + `getFieldInfo`, falling back to `routedFieldInfo.type` for `declaredType` when the routing payload lacks one (e.g. types discovered from `@address = Address.new` ctor assignments rather than YARD `@return [Type]`), and propagates `visibility` / `isStatic` / `isReadonly`. Pre-pass did none of this, so on the sequential path `resolveFieldAccessType` failed to walk chains where the type only came from the FieldExtractor. The pre-pass now mirrors parse-worker.ts:1803-1898 verbatim, with one deliberate difference: the FieldInfo cache is scoped to a single `processCalls` invocation rather than module-level (the worker process is short-lived; the main thread is not, and a module-level cache would leak state between analyze runs). Also drops the now-stale "Defer resolution: Ruby attr_accessor properties are registered during this same loop" comment on `pendingWrites.push` — the rationale is no longer accurate after Copilot's pre-pass, but the deferral is still needed so write-access tracking sees inference that completes during the main loop. Comment updated to reflect that. Verification: * `tsc --noEmit`: 0 errors * test/unit (call-processor, call-routing, field-extraction, ruby-self-call): 224 passing * test/integration (ruby, ruby-sequential-mixin, pipeline-graph-golden): 137 passing Co-Authored-By: Claude Opus 4.7 (1M context) * fix(call-processor): key fieldInfoCache by filePath:startIndex, not raw byte offset Claude's review of 255bdf6 caught a real collision in the FieldInfoCache I added: keying by `classNode.startIndex` alone is a per-file byte offset, so two files that both begin with a class at byte 0 — extremely common in Ruby / Python, where files frequently open with `class Foo`, `module Foo` — collide on the same cache entry. The second file's `getFieldInfo` then returns the first file's FieldInfo map, producing wrong `declaredType` / `visibility` / `isReadonly` on its properties. Same shape as the bug that already exists in parse-worker.ts:377 (also keyed by `classNode.startIndex` in a module-level map, persistent across files processed by the same worker). Fixing the symmetric pre-existing leak in parse-worker.ts is a separate, scoped follow-up — left out of this commit to keep the fix minimal and reviewable. Cache map and key are now both string-typed. Composite key `${context.filePath}:${classNode.startIndex}` keeps the within-file hit rate (one FieldExtractor.extract() per class regardless of how many `attr_accessor` lines it has) while eliminating cross-file aliasing.

The import resolver now strips JS-family extensions (.js/.jsx/.mjs/.cjs) and retries with TS equivalents (.ts/.tsx/.mts/.cts) when the literal .js file does not exist. This fallback only applies to TypeScript/JavaScript languages. Also adds .mts/.cts to the EXTENSIONS list for completeness. Fixes #1503 * fix: address review findings — normalization, edge-case tests, integration test - Fix makeCtx to use production normalization (.replace backslash) instead of .toLowerCase() (Finding 3) - Add tests for .mjs/.cjs with competing .ts/.mts siblings (Finding 1) - Add tests for ./dir.js → dir/index.ts boundary (Finding 2) - Add integration test verifying full pipeline CALLS edges for ESM .js imports (Finding 4) - Document path alias .js limitation as known follow-up (Finding 5) * chore(autofix): apply prettier + eslint fixes via /autofix command * chore: retrigger CI after bot-only tip commit Co-authored-by: Cursor --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Gergo Magyar Co-authored-by: Cursor --- .../ingestion/import-resolvers/standard.ts | 32 +++- .../core/ingestion/import-resolvers/utils.ts | 4 + .../typescript-esm-js-extension.test.ts | 62 +++++++ .../unit/esm-extension-resolution.test.ts | 153 ++++++++++++++++++ 4 files changed, 250 insertions(+), 1 deletion(-) create mode 100644 gitnexus/test/integration/resolvers/typescript-esm-js-extension.test.ts create mode 100644 gitnexus/test/unit/esm-extension-resolution.test.ts diff --git a/gitnexus/src/core/ingestion/import-resolvers/standard.ts b/gitnexus/src/core/ingestion/import-resolvers/standard.ts index f8aae9625..47e2dabb2 100644 --- a/gitnexus/src/core/ingestion/import-resolvers/standard.ts +++ b/gitnexus/src/core/ingestion/import-resolvers/standard.ts @@ -128,7 +128,21 @@ export const resolveImportPath = ( if (importPath.startsWith('.')) { const resolved = tryResolveWithExtensions(basePath, allFiles); - return cache(resolved); + if (resolved) return cache(resolved); + + // TypeScript ESM: imports use .js/.jsx/.mjs/.cjs but source files are + // .ts/.tsx/.mts/.cts.

Under heavy parallel search load (issue #1486: 180+ piled-up processes, load avg > 100), these accumulated faster than they completed because nothing capped concurrent in-flight augments. Add a lockfile-based concurrency guard under `<.gitnexus>/.hook-locks/`: each running hook claims a `.lock`, the guard counts live PIDs and prunes stale entries (>30s mtime or pid no longer alive), and bails silently when MAX_INFLIGHT (3) is reached. Augment is best-effort enrichment — missing a few fires under burst load is preferable to melting the system. Applied to all three hook variants that spawn augment: - gitnexus/hooks/claude/gitnexus-hook.cjs (npm-installed Claude hook) - gitnexus-claude-plugin/hooks/gitnexus-hook.js (plugin Claude hook) - gitnexus-cursor-integration/hooks/gitnexus-hook.cjs (Cursor hook) Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): make augment concurrency cap a hard cap via atomic slot files Address Claude's review of #1510. The original count-then-claim guard had a TOCTOU window: N hooks could each read `active < MAX_INFLIGHT` between readdirSync and the per-pid `wx` write and all proceed, briefly exceeding the cap. The PR title's "cap" language overstated this. Replace with fixed-name `slot-0.lock` ... `slot-N.lock` under `.hook-locks/`. `O_CREAT|O_EXCL` on a fixed path is OS-atomic — exactly one process wins each slot, so the cap is hard regardless of burst arrival timing. Each slot file contains the owning PID so stale-takeover still works when a hook crashes without releasing. PID liveness is checked before age (Claude's Finding 3): a slow-but-alive hook is never wrongly evicted. The 30s age window only kicks in to defend against PID reuse on a long-abandoned slot, well above the 7s augment timeout so a healthy run never hits it. Also adds the missing concurrency-guard tests to cursor-hook.test.ts (Claude's Finding 2): source-level wiring + dead-PID reclaim + 3-slots-full bail. Previously only the CJS and Plugin variants had test coverage for the guard; the Cursor variant was validated only by code inspection. Tests: 5726 passing, +9 from baseline (1 hard-cap burst test + 4 source regressions in hooks.test.ts; 3 source + 2 integration in cursor-hook.test.ts). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): inspect slot mtime + content via single fd (codeql TOCTOU) CodeQL flagged the stale-takeover path in acquireHookSlot as a potential filesystem race (js/file-system-race): statSync(slotPath) followed by readFileSync(slotPath) gives a TOCTOU window where the file could be swapped between the metadata check and the content read. Replace the two separate path-based calls with a single openSync + fstatSync + readSync + closeSync sequence. Both mtime and owner PID now come from the same file descriptor, so the operations are atomic on one inode. No behavioral change beyond closing the race. Applied to all three hook variants (CJS, Plugin, Cursor). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): distinguish EPERM from ESRCH in PID liveness check Cursor Bugbot caught a contradiction with the stated design: the bare `catch` after `process.kill(owner, 0)` was treating EPERM (process exists but owned by another user) the same as ESRCH (process gone), which would evict a live slot whenever the lock dir straddled user boundaries. Inspect the error code: ESRCH → dead, evict; EPERM → still alive, keep the slot; anything else → assume alive (be conservative under unexpected failure rather than over-evict). Applied to all three hook variants. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): fail closed when lock dir cannot be created Previously the mkdirSync catch in acquireHookSlot returned `() => {}` (a truthy no-op). The caller checks `if (!release) return;` to skip augment when the guard can't be established — but a truthy no-op slipped through that check and let augment spawn unguarded. On a cross-user shared `.gitnexus/` or read-only filesystem, N concurrent hooks would each take that branch and reintroduce the #1486 fan-out the guard exists to prevent. Return `null` instead so the caller's `if (!release) return;` skips augment cleanly. Augment is best-effort enrichment — skipping it when the guard fails is strictly safer than running unguarded. Also clarify the stale-slot comment: PID-liveness wins for slots younger than HOOK_LOCK_STALE_MS, but age is the final arbiter beyond 30s (PID-reuse defense). The previous wording said "PID-liveness wins over age" without qualifying it, which contradicted the >30s branch. Add source-level regression tests in hooks.test.ts and cursor-hook.test.ts asserting acquireHookSlot returns null (not () => {}) on lock-dir failure. Note in the Cursor test file that the 10-spawner burst test is not duplicated because the algorithm is byte-for-byte identical to the CJS hook and already covered there.

The for-loop then crashes with "bm25Results is not iterable". - mergeWithRRF: default both inputs via ?? [] so undefined never reaches the iteration loops - hybridSearch: wrap searchFTSFromLbug in try/catch and fall back to semantic-only search instead of crashing - local-backend query handler: guard bm25SearchResult?.results and semanticResults with ?? [] - bm25Search: wrap the dynamic import in try/catch for sandboxed MCP contexts; guard ftsResponse?.results Adds 6 regression tests covering undefined inputs and FTS failure fallback. Fixes #1489 * fix(search): address review findings on #1489 crash guards - Guard ftsResponse.results with ??

Lets users maintain lean custom context without it being overwritten on every reindex. Co-Authored-By: Claude Opus 4.6 (1M context) * feat: improve gitnexus:keep marker to reliably preserve custom sections The `` marker inside a GitNexus block tells `analyze` to only update the stats line (node/edge/flow counts) while preserving the user's custom layout. This lets teams trim the verbose default template to a lean format without having it overwritten on every reindex. Changes: - Broaden stats-line regex to match both "Indexed as" and "indexed by GitNexus as" formats - Improve stats extraction from generated content (prefer structured match over greedy parentheses) - If keep marker is present but no stats line found, preserve the section as-is instead of falling through to full replace - Add tests for keep preservation and no-keep replacement Co-Authored-By: Claude Opus 4.6 (1M context) * fix: address PR #1508 review findings (F1-F5) Refactor the keep-marker stats-update path and close the test-coverage gaps surfaced by the production-readiness review. ## Findings 2 + 3 (high) — fragile extraction → silent corruption Stop re-extracting `newName` (first `**bold**`) and `newStats` (first `(...)`, with fallback) from generated content. Both are structurally fragile: - F2: newName silently picks the wrong value if the template ever emits bold text before the project-name line (no current bug; an unstated contract with no enforcement) - F3: newStats fallback `\(([^)]+)\)` matches `({target: "symbolName", direction: "upstream"})` from the Always-Do bullet when `noStats: true` suppresses the canonical stats line, silently corrupting the stats output Fix: pass `projectName: string` and `stats: RepoStats` directly into `upsertGitNexusSection`. Build the stats line from those values. Both callers in `generateAIContextFiles` already have them in scope. ## Finding 1 (high) — misleading return value When a keep marker is present but no stats line matches the pattern, the function previously returned `'updated'` without writing, producing `CLAUDE.md (updated)` in CLI output for a file that was not touched. Add a distinct `'preserved'` return variant; CLI now reports `CLAUDE.md (preserved)` honestly. ## Finding 4 (medium) — unanchored stats regex `/(?:Indexed as|...) \*\*[^*]+\*\* \([^)]+\)/` could match prose embedded mid-paragraph in user content (e.g. "you'll see it Indexed as **Foo** (note: ...)"). Anchor with `^...$` plus the `m` flag so only standalone stats lines match. ## Finding 5 — test coverage gaps Seven new tests, each cross-referenced to the review finding: - keep marker OUTSIDE the GitNexus section has no effect - AGENTS.md keep path preserves custom layout (parity with CLAUDE.md) - idempotent: second run produces byte-identical output - CRLF file with keep marker: stats line updates correctly - noStats + keep marker: not corrupted by Always-Do tuple text (F3 regression guard) - returns 'preserved' (not 'updated') when no stats line matches (F1 regression guard) - project name with markdown punctuation (hyphens/slash/dot) lands intact All 23 ai-context tests pass; typecheck, prettier, eslint clean. * docs(ai-context): address PR #1508 review findings on keep-marker path - Clarify that noStats affects generated template only, not keep-section stats updates - Fix stats-line regex comment to match behavior (no end anchor; trailing suffix kept) - Assert '. MCP tools.' survives stats replacement in preserve-custom-section test - Document LF normalization when rewriting CRLF seed in keep-marker CRLF test Co-authored-by: Cursor --------- Co-authored-by: Claude Opus 4.6 (1M context) Co-authored-by: dp-web4 Co-authored-by: Gergő Magyar Co-authored-by: Cursor --- gitnexus/src/cli/ai-context.ts | 53 ++++- gitnexus/test/unit/ai-context.test.ts | 310 +++++++++++++++++++++++++- 2 files changed, 358 insertions(+), 5 deletions(-) diff --git a/gitnexus/src/cli/ai-context.ts b/gitnexus/src/cli/ai-context.ts index 8e18fed7d..42dcb7aa7 100644 --- a/gitnexus/src/cli/ai-context.ts +++ b/gitnexus/src/cli/ai-context.ts @@ -199,7 +199,9 @@ async function fileExists(filePath: string): Promise { async function upsertGitNexusSection( filePath: string, content: string, -): Promise<'created' | 'updated' | 'appended'> { + projectName: string, + stats: RepoStats, +): Promise<'created' | 'updated' | 'appended' | 'preserved'> { const exists = await fileExists(filePath); if (!exists) { @@ -223,7 +225,50 @@ async function upsertGitNexusSection( ); if (startIdx !== -1 && endIdx !== -1 && endIdx > startIdx) { - // Replace existing section + const existingSection = existingContent.substring( + startIdx, + endIdx + GITNEXUS_END_MARKER.length, + ); + + // If the existing section contains , preserve the user's + // custom layout and only update the stats line (node/edge/flow counts). + // This lets teams trim the verbose default template to a lean format without + // having it overwritten on every `gitnexus analyze`. + // + // Note: the keep-marker check operates on `existingSection` (the substring + // between valid section markers identified by findSectionMarkerIndex), so + // a keep marker in user prose OUTSIDE the GitNexus block has no effect. + if (existingSection.includes('')) { + // Build the new stats line from the caller-provided values directly. + // We do NOT re-extract from `content` because: + // (a) first-bold extraction is fragile if the template evolves + // (b) the parenthesized-text fallback can match unrelated tuples + // like `({target: "symbolName", direction: "upstream"})` + // when noStats is set + // Passing projectName + stats explicitly makes the contract obvious. + // noStats controls template generation, not keep-section stat updates — the user opted into a stats line by keeping it. + const newStatsInner = `${stats.nodes || 0} symbols, ${stats.edges || 0} relationships, ${stats.processes || 0} execution flows`; + const statsLine = `Indexed as **${projectName}** (${newStatsInner})`; + + // Match either canonical phrasing at line start (`^` with `m` flag) so we + // cannot replace prose embedded mid-paragraph.

The `--no-stats` flag on `gitnexus analyze` was advertised as "Omit volatile file/symbol counts from AGENTS.md and CLAUDE.md" but had no effect: every reindex still rewrote the markdown with fresh count phrases, producing chore-commit churn on every run — the exact problem the flag was added to solve in #704. Root cause is commander.js negation-flag semantics. `.option( '--no-stats', ...)` registers the option under the accessor `stats` (boolean, default `true`; `false` when the flag is passed), NOT `noStats`. The two action-handler reads in `analyze.ts` (lines 414 and 500 pre-fix) read `options?.noStats`, which is always `undefined`, so the `noStats` payload always reached `runFullAnalysis` / `generateAIContextFiles` as `undefined`/falsy and the count branch in the template always fired. Fixed by replacing `options?.noStats` with `options?.stats === false` at both reads. The strict `=== false` check (rather than `!options?.stats`) means absent options or absent `.stats` field fall through as no-stats=false, preserving the documented default-on behaviour. Also updated the `AnalyzeOptions` interface to declare `stats?: boolean` (matching commander's actual output) with a JSDoc explaining the negation, since the prior `noStats?: boolean` shape was a static-type misrepresentation of what commander provides at runtime. Internal call sites that re-pack `{ noStats: ... }` for downstream consumers (`run-analyze.ts`, `ai-context.ts`) keep their existing field name — those interfaces are not commander- shaped, so `noStats` is the correct name there. ## Regression tests Two new unit tests in `test/unit/ai-context.test.ts`: * `omits volatile counts when noStats option is set (#1477)` — asserts the count parenthetical is absent from both CLAUDE.md and AGENTS.md when `noStats: true` is passed. * `preserves volatile counts when noStats is not set (default)` — documents the default-on path so a future refactor can't silently flip the default. Both call `generateAIContextFiles` directly with distinctive numbers that would unmistakably leak through if the omit branch is broken. ## Manual verification * `vitest run test/unit/ai-context.test.ts` → 13/13 pass (11 prior + 2 new). * Verified before-fix behaviour by checking out main, running `npx gitnexus analyze --no-stats` against an indexed repo, and observing the count phrase still present. Re-running on the fix branch with the same flag strips the phrase as documented. Co-Authored-By: Claude Opus 4.7 (1M context) * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(cli): resolve merge conflict markers in analyze.ts (PR #1478) Remove leftover conflict hunks from main merge; keep commander stats shape (stats?: boolean), wire noStats: options?.stats === false into runFullAnalysis and generateAIContextFiles, and retain indexOnly / skipSkills / skipAgentsMd wiring from main.

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(cpp): complete scope-resolution parity * fix(ci): resolve formatting, lint errors for PR #1520 - prettier: format arity-metadata.ts, captures.ts, index.ts - eslint: rename unused HEADER_GLOB to _HEADER_GLOB - eslint: replace unsafe parser.parse() with parseSourceSafe() - eslint: suppress intentional console.warn/log in sync.ts - eslint: remove unused _it import alias in cpp.test.ts * fix(ci): complete formatting, lint, and typecheck fixes - prettier: format call-processor.ts, imported-return-types.ts, include-extractor.test.ts, cpp-captures.test.ts, cpp-imports.test.ts - eslint: suppress intentional console.warn in manifest-extractor.ts - typecheck: restore 'thrift' in ContractType union (was accidentally removed) and add thrift case to exhaustive switch in manifest-extractor * fix(ci): revert unintended group module changes that broke tests Restore types.ts, config-parser.ts, matching.ts, sync.ts, and manifest-extractor.ts to upstream/main versions. The original commit accidentally removed fields (thrift, workspace_deps, exclude_links_paths, exclude_links_param_only_paths) from DetectConfig/MatchingConfig/ContractType which are still referenced by matching.test.ts, config-parser.test.ts, sync.test.ts and other integration tests. This PR's scope is C++ scope-resolution parity only — group module type definitions and logic should remain unchanged. * fix(codeql): address security and quality alerts - arity-metadata.ts, interpret.ts: replace single-pass template strip regex (/<[^>]*>/g) with a while-loop to fully handle nested templates like Map> — resolves 'Incomplete multi-character sanitization' - cpp.test.ts: remove unused vitest 'it' import since the file defines its own 'it' via createResolverParityIt — resolves 'Assignment to constant' - include-extractor.test.ts: use fs.mkdtempSync() instead of predictable os.tmpdir()+Date.now() paths — resolves 'Insecure temporary file' - interpret.ts: remove redundant 'name !== undefined' check (already guaranteed by early return) — resolves 'Comparison between inconvertible types' * review: address Claude review findings on PR #1520 - Findings 1-3 (BLOCKERS): restore include-extractor.ts and its test to the main baseline. Block-comment fallback regression, suffix-resolve false-positive suppression, and the four deleted regression tests (#3-#6) are now back. These changes were unrelated to C++ scope parity and should not have been in this PR. - Finding 4 (MAJOR, partial): revert COMPOUND_RECEIVER_MAX_DEPTH 6 to 4. No C++ test exercises depth > 4 (cpp-chain-call uses a 2-hop chain), so the bump risked silent regressions on other migrated languages without justification. The wildcard-origin propagation in imported-return-types.ts is retained — C++ #include and using namespace both emit wildcard-origin bindings (cpp/import-decomposer .ts:40,90), so wildcard propagation is causal to C++ parity. - Finding 6: tighten write-access dedup test with exact per-field counts (nameWrites = 2, addrWrites = 1) instead of total-count + sub string containment, so a regression in one of the two name writes can no longer be masked. - Finding 8: skipped. Box-drawing characters in cpp/query.ts comments match the established convention used in csharp/java/php query files. Finding 5 (int/long normalization tie-breaker) left as documented follow-up — proper fix requires resolver-level tie-breaker logic and risks regressing other arity-matching tests. * fix(cpp): stop #include from leaking class methods and namespace members (U1) The C++ registry-primary resolver was emitting impossible CALLS edges for ordinary headers: an including file's unqualified save() resolved to User::save and unqualified foo() resolved to ns::foo. Two leak paths converged on localDefs: 1. expandCppWildcardNames (file-local-linkage.ts) iterated the flattened localDefs and exported every simple tail, including class-owned methods and namespace-contained symbols. Replaced with a scope-aware filter: build nodeId -> owning Scope from Scope.ownedDefs and skip defs whose owning scope is Namespace or Class. 2. The shared global free-call fallback's pickUniqueGlobalCallable walks the workspace registry by simple name and would still hit class methods / namespace members even with wildcard expansion fixed. Plugged the gap via the existing isFileLocalDef hook — semantically 'logically invisible cross-file' — by tracking per- file non-globally-visible nodeIds (populateCppNonGloballyVisible, called from populateOwners) and adding an ownerId !== undefined fast-path for class-owned defs. Side fix in shared finalize-algorithm.ts: when wildcard expansion resolves to a real target but produces zero propagating names, the edge was dropped, taking the file-level IMPORTS edge with it. Preserve the original wildcard edge so #include dependencies survive even when the header exposes no unqualified bindings. Tests: cpp-include-no-class-leak, cpp-include-no-namespace-leak, and cpp-anon-ns-same-file-visible fixtures. Negative tests mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-failures registry — legacy DAG has no scope-aware filtering on the global fallback; backporting is out of scope. All 2104 resolver integration tests pass under registry-primary mode. * fix(cpp): suppress receiver-bound CALLS when integer-width overloads collide (U2) C++ arity-metadata normalizes int, long, short, unsigned, size_t to 'int' so single-candidate flows like 'process(42L)' match a 'long'- typed parameter via loose matching. But when both 'process(int)' and 'process(long)' coexist as method overloads, they both end up with parameterTypes=['int'] in the registry, and pickOverload's narrowing returns 2 candidates with no way to disambiguate. The previous code picked candidates[0] arbitrarily, emitting a CALLS edge to the wrong overload roughly half the time. Fix: - Add isOverloadAmbiguousAfterNormalization in overload-narrowing.ts that detects >1 candidate sharing identical parameterTypes sequences. - Have pickOverload return a new OVERLOAD_AMBIGUOUS sentinel when this fires. - In the receiver-bound-calls loop, when pickOverload signals ambiguity, suppress the edge AND add the site to handledSites so the late-stage emitReferencesViaLookup pass does not re-emit the pre-resolved reference. Without the handled-mark, the reference index still carries a toDef and emits the same wrong edge. Graph schema has no ambiguous-target edge model, so emitting two edges (one per candidate) would require a separate schema change. Zero-edge is the only safe outcome. Other languages: the ambiguity check is a precondition gate, not a behavior change for normal narrowing. Languages whose normalizers do not collapse distinct types into a single token (verified by grep over *-arity-metadata.ts) will never produce >1 candidate with identical parameterTypes from genuinely distinct declarations, so the branch is effectively C++-only in practice. Test: cpp-overload-int-long fixture asserts exactly .toBe(0) CALLS edges. Count=1 = arbitrary pick (the bug); count>1 = unsupported ambiguous-edge model. Mode-gated to REGISTRY_PRIMARY_CPP=1 — legacy DAG has no OVERLOAD_AMBIGUOUS wiring; backporting is out of scope. All 2105 resolver integration tests pass under registry-primary; all 139 cpp tests pass under both modes (3 negative tests skipped in legacy as documented). * test(cpp): add integration coverage for anonymous-namespace, using-namespace conflict, and std-shim leakage (U3+U4+U5) Three new end-to-end fixtures exercise the resolver pipeline against scenarios that previously had only unit-level coverage or no coverage at all (Claude review Finding 7): U3 — cpp-anon-ns-cross-file: helper.cpp declares 'namespace { void worker(); }' and calls it internally. caller.cpp declares a separate 'void worker()' and calls it. Asserts (a) the cross-file CALLS edge from caller's run() does not target helper.cpp's anonymous-namespace worker, and (b) the same-file edge from helper_entry() to its own worker still resolves (positive guard against a 'no edges at all' regression making the negative check vacuously pass). Includes a state-isolation guard that re-runs the same fixture and asserts identical results, proving clearFileLocalNames() is called by the pipeline entry. U4 — cpp-using-namespace-conflict: Two headers each declaring 'namespace a { foo() }' and 'namespace b { foo() }' respectively, plus a caller doing 'using namespace a; using namespace b; foo()'. Asserts exactly zero CALLS edges. One edge = arbitrary pick (the bug); two edges would require an ambiguous-target edge model GitNexus does not have. Depends on U1 — without scope-aware filtering, both foo()s would already be in the importer's wildcard binding set as simple 'foo', so the test would pass for the wrong reason. U5 — cpp-using-namespace-std-smoke: Fixture-local 'namespace std { void cout_write(); void println(); }' shim rather than real — captures the wildcard-leak shape deterministically without depending on system-header modeling stability (out of scope per plan). Asserts (a) the project-local call resolves correctly, (b) no leak to shim STL symbols, and (c) no CALLS/ACCESSES edges from the caller into std-shim.h at all. Negative tests for U2/U4 mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-failures registry; legacy DAG lacks the OVERLOAD_AMBIGUOUS suppression and the namespace-aware filtering, so the leaks persist there. All 2112 resolver integration tests pass under registry-primary; all 146 cpp tests pass under both modes (4 negative tests skipped in legacy as documented). * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(cpp): scope-aware isSuperReceiver classification (U1) The C++ isSuperReceiver hook used a regex `/^[A-Z]\w*::/` that misclassified any uppercase-qualified call as a super-receiver call. Singleton::getInstance(), std::Foo::bar(), and PascalCase namespace calls all entered the super branch, where the absence of an enclosing class (or wrong MRO context) dropped the resolution entirely. Fix: - New optional ScopeResolver hook isSuperReceiverInContext(text, callerScope, scopes). Languages where super classification depends on caller context define it; receiver-bound-calls.ts prefers it when defined and falls back to the simple isSuperReceiver(text) otherwise. Other migrated languages (Python, Java, C#, PHP, Go, TypeScript) are unchanged. - C++ implementation: parse the LHS of '::' from the receiver text, resolve via findClassBindingInScope, and return true only when the LHS is a class-like def in the caller's enclosing class's MRO. Returns false for namespace LHS, unresolved LHS, self-class LHS (qualified self-calls aren't super), and any non-'::' form. - Extended the C++ tree-sitter query to capture the LHS of qualified_identifier as @reference.receiver so qualified static member calls (Singleton::getInstance()) reach the receiver-bound Case 2 (class-name receiver) path. Without the receiver capture, qualified calls had no explicit receiver and could not resolve through any receiver-bound branch. Test: cpp-namespace-qualified-not-super fixture. Singleton::getInstance() from a free function asserts exactly 1 CALLS edge through the qualified-call path. Passes under both REGISTRY_PRIMARY_CPP=1 and =0. All 2113 resolver integration tests pass; all 147 cpp tests pass under both modes. * fix(cpp): suppress receiver-bound CALLS when default-arg overloads collide (U4) ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and 'void f(int, int = 0)' are declared on S. The previous resolver returned the first viable candidate via pickOverload's fallback. Extended isOverloadAmbiguousAfterNormalization to take an optional argCount: when provided, the predicate compares only the first argCount slots of each candidate's parameterTypes. Candidates whose declared-prefix matches up to argCount are treated as ambiguous because default arguments make all of them equally viable for the call. Without argCount, behavior is unchanged (the original int/long normalization-collapse contract, full-length equality required). pickOverload now passes site.arity so default-arg ambiguity fires. Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges. Passes under both REGISTRY_PRIMARY_CPP=1 and =0. All 2114 resolver integration tests pass; all 148 cpp tests pass under both modes. * fix(cpp): two-phase template lookup suppresses dependent-base members (U3) ISO C++ two-phase name lookup: inside a class template body, unqualified calls MUST NOT bind to members of a dependent base class. Only this->name or Base::name forms make the lookup dependent. GCC and Clang both reject the unqualified form with 'declaration of f must be available'. Before this fix, GitNexus's global free-call fallback walked the workspace registry by simple name and bound unqualified calls inside template bodies to dependent-base members, producing CALLS edges the compiler would reject. Implementation: - New languages/cpp/two-phase-lookup.ts module: per-pipeline state recording (className, dependentBaseName) pairs at capture time and resolving them to nodeId sets during populateOwners. - captures.ts detectCppDependentBases walks the AST once finding every template_declaration containing a class/struct definition. For each, it collects template-parameter names (typename T, class T, non-type int N, template-template parameters) and walks each base in the base_class_clause checking whether any inner type_identifier matches a template parameter. Conservative bias: typename T::U, decltype, and template-template-parameter shapes also classified as dependent. - Extended scope-resolution contract's isCallableVisibleFromCaller hook with optional callerScope and scopes fields. C++ implements the hook to consult isCppDependentBaseMember: when the candidate is a member of a dependent base of the caller's enclosing class, the hook returns false and pickUniqueGlobalCallable skips the candidate. - clearFileLocalNames also clears the dependent-base state per pipeline run. Fixtures: - cpp-two-phase-dependent-base: Derived deriving from Base, unqualified f() and i inside Derived's body. Asserts zero CALLS edges and zero ACCESSES edges respectively. - cpp-two-phase-this-qualified, cpp-two-phase-non-dependent-base, cpp-two-phase-namespace-free-call-inside-template: positive fixtures left as documented gaps (this-> and qualified-name resolution inside template bodies are pre-existing resolver weaknesses independent of U3). Tracked separately. Negative test mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected- failures registry; legacy DAG has no two-phase lookup. All 2116 resolver integration tests pass under registry-primary; all 150 cpp tests pass under both modes (5 negative tests skipped in legacy as documented). * fix(cpp): implement V1 ADL (Koenig lookup) for free-function calls (U2) Plan 2026-05-13-001 U2. Adds argument-dependent lookup as a new candidate-generating tier in `emitFreeCallFallback`: when ordinary unqualified lookup is empty, ADL surfaces candidates from each value-class-typed argument's enclosing namespace. V1 boundary (locked by cpp-adl-pointer-arg-boundary fixture): - only direct enclosing-namespace closure - only directly-named class-type values (pointer / reference / template- spec args excluded; closure rules deferred to V2) - ADL fires ONLY when ordinary lookup is empty (no union-and-resolve) Parenthesized name `(f)(s)` suppresses ADL per ISO C++ [basic.lookup.argdep]/3.1. Multi-candidate ambiguity (e.g. `process(int)` vs `process(long)` after C++ int-width normalization) returns the ADL_AMBIGUOUS sentinel — caller suppresses entirely, mirroring the OVERLOAD_AMBIGUOUS contract from plan 2026-05-12-002 U2. Implementation: - `cpp/adl.ts` — new module: per-pipeline argInfoBySite + noAdlSites Maps populated at capture time, classToNamespaceQualifiedName Map populated during populateOwners; `pickCppAdlCandidates` returns SymbolDefinition | ADL_AMBIGUOUS | undefined - `scope-resolution/contract/scope-resolver.ts` — adds optional `resolveAdlCandidates` hook - `scope-resolution/passes/free-call-fallback.ts` — invokes ADL hook between `findCallableBindingInScope` and `pickUniqueGlobalCallable`; marks site handled on `'ambiguous'` so emit-references doesn't retry - `cpp/captures.ts` — detects `parenthesized_expression` function wrap; per-arg classification (pointer/reference/value class) preserving the shape info the existing arity-narrowing normalizer strips - `cpp/scope-resolver.ts` — registers hook, populates associated namespaces, clears state in loadResolutionConfig Negative tests (parens, pointer-boundary, ambiguous) gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG has no V1/V2 ADL boundary or ADL_AMBIGUOUS suppression. 154/154 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1; 147 pass + 7 skipped under =0 (legacy parity baseline). * fix(cpp): inline namespace transitive walking + qualified namespace resolution (U5) Plan 2026-05-13-001 U5. Two ISO C++ inline-namespace semantics: 1. Unqualified-lookup transitive visibility: inline-namespace members reach the enclosing namespace's scope as if declared there. The `populateCppNonGloballyVisible` exemption keeps them globally visible so cross-file unqualified lookup finds them. 2. Qualified-receiver transitive visibility: `outer::foo()` resolves to `outer::v1::foo()` when `v1` is inline (and through arbitrarily-deep nesting like `outer::v1::experimental::foo`, matching libc++ `__1` / libstdc++ `__cxx11`). The second behavior required a new resolver case in `receiver-bound-calls.ts` (Case 1.5: language-specific qualified-receiver member lookup) because C++ qualified-namespace member calls had no prior resolution path — receiver-bound Case 1 only handled `ParsedImport.kind === 'namespace'` (Python/JS-style) and Case 2 handles class receivers, neither of which fired for `outer::foo()`. The new hook `resolveQualifiedReceiverMember` is opt-in; languages without C++-style qualified-name semantics omit it. Implementation: - `cpp/inline-namespaces.ts` — new module: per-pipeline `inlineNamespaceRangesByFile` + `inlineNamespaceScopeIds` Sets; `markCppInlineNamespaceRange` at capture time; `populateCppInlineNamespaceScopes` resolves ranges → scope IDs; `resolveCppQualifiedNamespaceMember` walks namespace scopes by simple name and descends transitively through inline children only. - `scope-resolution/contract/scope-resolver.ts` — adds optional `resolveQualifiedReceiverMember` hook to the contract. - `scope-resolution/passes/receiver-bound-calls.ts` — Case 1.5 invokes the hook between Case 1 (namespace imports) and Case 2 (class-name receiver). Returns undefined for non-namespace receivers so Case 2 still resolves class-qualified calls. - `cpp/captures.ts` — detects `inline` keyword child on `namespace_definition`; records 1-based range to match Scope.range. - `cpp/file-local-linkage.ts` — `populateCppNonGloballyVisible` exempts inline-namespace scopes so cross-file unqualified lookup keeps their members visible. - `cpp/scope-resolver.ts` — wires `populateCppInlineNamespaceScopes` into populateOwners (BEFORE `populateCppNonGloballyVisible` so the exemption sees populated state); registers `resolveQualifiedReceiverMember` hook. 4 fixtures: `cpp-inline-namespace-unqualified`, `-versioned`, `-nested` (two transitive inline hops, STL `__1` shape), and `-adl-participation` (composes with U2 — ADL surfaces records declared inside inline child namespaces). All 4 assert exactly 1 CALLS edge with correct target file. Versioned fixture gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG can't disambiguate two same-name foos without inline awareness. Other 3 coincidentally resolve in legacy. 158/158 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1; 150 pass + 8 skipped under =0 (legacy parity baseline). * test(cpp): Phase 5 cross-unit composition tests for U1/U2/U3/U5 Plan 2026-05-13-001 Phase 5. Locks in correct behavior at the intersections between the previously-shipped scope-resolver units. Enhancement to U1: `isSuperReceiverInContext` strips template-argument lists (`Base` → `Base`) and namespace prefixes (`outer::v1::Base` → `Base`) before resolving the receiver in the caller's scope chain. This makes the super-receiver classification work for template-class heritage shapes like `Base::method()` and `outer::v1::Base::f()`. Three fixtures + four tests: - `cpp-phase5-u1-u3-qualified-base-call`: `template struct Derived : Base` with `Base::method()` inside a template body. Asserts NO mis-routing (count = 0) — documents the V1 gap that template-class inheritance isn't captured as EXTENDS by the legacy DAG, so MRO walks are empty and the super branch can't dispatch. The composition still works correctly: U1's template-arg-stripping classifies `Base` as a super candidate, but the empty-MRO terminates without false edges. - `cpp-phase5-u2-u3-adl-from-derived`: `Derived : Base` where `Base::record` shadows `audit::record`. Unqualified `record(e)` inside the template body should resolve via ADL to `audit::record` (because U3 + the `isFileLocalDef` class- owned filter suppress `Base::record`). Asserts 1 edge to audit.h and 0 edges to base.h. - `cpp-phase5-u3-u5-inline-base`: `template struct Derived : outer::v1::Base` where `v1` is inline. Unqualified `f()` inside `Derived::g()` should NOT bind to Base::f (dependent-base suppression even across inline namespace prefix). Asserts count = 0. Phase 5 tests asserting no-false-positives are gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG over- resolves without the template-arg-stripping qualified-receiver path and without two-phase dependent-base suppression. 162/162 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1; 152 pass + 10 skipped under =0 (legacy parity baseline). --------- Co-authored-by:

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix: apply ESM .js extension fallback to tsconfig path alias resolution Path alias imports (e.g. `@/utils.js` via tsconfig paths) now correctly strip JS-family extensions and retry with TS equivalents when the literal .js file does not exist. This applies the same stripJsExtension fallback already used for relative imports to the alias resolution branch. Fixes #1528 * chore(autofix): apply prettier + eslint fixes via /autofix command * test(esm): cover .mjs/.cjs path-alias extension resolution Co-authored-by: Cursor * test(esm): use Map for path aliases in resolveWithAlias helper Matches TsconfigPaths.aliases from language-config. CI cannot run tsc -p tsconfig.test.json yet: the project has hundreds of pre-existing errors under test/ (fixtures + unit/integration); enable that step after backlog cleanup.

P1: - Plugin copy of `win-rm-list-json.ps1` gains `Pack = 4` so its CLR struct matches the 12-byte native `RM_UNIQUE_PROCESS` layout (multi-blocker `RmGetList` no longer reads mangled `dwProcessId`). - `GITNEXUS_HOOK_CLI_PATH = ''` now falls through to the resolution chain in `gitnexus-hook.cjs`, matching the plugin copy and removing the twin-file divergence on empty-string envs. - Lock-warning suppression test seeds `gitnexusMarkerPath` and asserts the augment subprocess actually ran, plus `GITNEXUS_DEBUG=1` preserves the full discarded prefix. - MCP-owner skip branch in both hook copies now emits `[GitNexus] augment skipped: MCP server owns DB` on stderr, so agents can distinguish intentional skip from silent failure. P2: - `ps` loop in `hook-db-lock-probe.cjs` fails-closed on `ETIMEDOUT` to mirror the `lsof` handling (symmetric subprocess-probe contract). - `RmStartSession` return value captured in both `.ps1` copies; exits early with `[]` on non-zero so subsequent RM API calls don't operate on an invalid handle. - Windows RM-list `.ps1` encoded cache distinguishes uninitialized (`undefined`) from load-failed (`null`) with a one-shot `GITNEXUS_DEBUG` warning instead of silently caching empty string. - `createHookToolDir` helper accepts `lsofOutputLines` and `psOutputByPid`; the multi-PID test uses them instead of duplicating the fake-binary construction inline. - All five skip-path tests now assert `result.status === 0` and the new skip-signal stderr line. - `AGENTS.md` documents the seven hook configuration env vars (`GITNEXUS_HOOK_CLI_PATH`, `_LSOF_PATH`, `_PS_PATH`, `_POWERSHELL_PATH`, `_LINUX_PROC_BUDGET_MS`, `_RM_TARGET`, `GITNEXUS_DEBUG`). - `GITNEXUS_DEBUG` path in `gitnexus-hook.cjs`/`.js` writes the full discarded stderr prefix instead of a 180-char preview. - Inline comment in `hook-db-lock-probe.cjs` explains the intentional Windows ETIMEDOUT fail-closed semantics. - Removed the unnecessary `as WriteFileOptions` cast and orphaned `import type { WriteFileOptions }` in `hooks.test.ts`. P3: - `isGitNexusServerCommand` unexported from `hook-db-lock-probe.cjs` (kept as private helper). - Env-path overrides (`GITNEXUS_HOOK_CLI_PATH`, `_POWERSHELL_PATH`, `_LSOF_PATH`, `_PS_PATH`) require `fs.existsSync` before being returned, so typos / stale config fall through to the standard resolution chain. Misc: - `gitnexus/package.json` engines.node back to `>=22.0.0` (matches origin/main and the original PR reviewer's earlier request). Twin-tree parity / CI sync mechanism tracked separately at abhigyanpatwari/GitNexus#1591.

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(cli): tolerate read-only workspace in ensureGitNexusIgnored The documented Docker workflow mounts the host workspace at /workspace:ro and runs `gitnexus index /workspace/` against an index produced by a prior host-side `analyze`. Since PR #1248 ("keep GitNexus ignores inside .gitnexus") the index command has called `ensureGitNexusIgnored`, which unconditionally writes `/.gitnexus/.gitignore` and `/.git/info/exclude` — both fail with EROFS on the :ro bind mount even though the host already wrote the correct file during `analyze`. Two complementary changes: 1. Idempotent fast path. Read the existing .gitnexus/.gitignore content first; if it already matches the desired value (`*\n`), skip the write entirely. This is the common case for the Docker workflow and avoids touching the FS at all. 2. EROFS/EACCES tolerance. When a write is genuinely needed but the FS refuses it, log a structured warning via the existing pino logger and continue. `registerRepo` runs before `ensureGitNexusIgnored` in `indexCommand`, so the global-registry write is already committed when we get here — letting the gitignore-write failure propagate leaves the user with a registered-but-error-exited command. Three new unit tests pin the behaviour: - idempotent re-call leaves mtime untouched - ENOENT-then-correct path on a writable parent succeeds - :ro parent (simulated via chmod 0o555) does not throw, on the already-correct fast path and on the cold-create path Existing tests (61) still pass. Closes #1549. * test(storage): cover read-only ignore paths and tolerate EPERM (#1550) - Add isReadOnlyFilesystemError helper including EPERM alongside EROFS/EACCES for ensureGitNexusIgnored and ensureGitInfoExclude (Windows parity with lbug-config / bridge-db patterns). - Skip chmod-based read-only tests on win32 and uid 0; assert logger.warn on POSIX chmod denial for missing .gitignore. - Add repo-manager-ensure-ignore-readonly.test.ts with vi.mock fs/promises delegating writeFile so EROFS/EACCES/EPERM rejections are asserted with structured log path and message for both .gitignore and .git/info/exclude.

The registry-primary path was filtering these defs out of `expandCppWildcardNames` via both the structural Namespace-owner check and the `isFileLocal` mark, so `hidden_probe(d)` from a TU including the header resolved to nothing while the legacy DAG returned the correct edge. Track anonymous-`namespace_definition` source ranges at capture time, resolve them to ScopeIds in `populateOwners` (parallels inline-namespace handling), and exempt those scopes from the two wildcard-expansion filters plus the `populateCppNonGloballyVisible` structural set. `markFileLocal` is preserved so the global free-call fallback still blocks cross-TU leaks for files that do NOT #include the declaring file (cpp-anon-ns-cross-file guard still passes). --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> Co-authored-by: Gergo Magyar --- .../src/core/ingestion/languages/cpp/adl.ts | 38 +++++--- .../core/ingestion/languages/cpp/captures.ts | 33 +++++-- .../languages/cpp/file-local-linkage.ts | 90 ++++++++++++++++++- .../ingestion/languages/cpp/scope-resolver.ts | 8 +- .../app.cpp | 14 +++ .../base_lib.h | 11 +++ .../app.cpp | 16 ++++ .../base_lib.h | 6 ++ .../app.cpp | 22 +++++ .../base_lib.h | 20 +++++ .../test/integration/resolvers/cpp.test.ts | 86 ++++++++++++++++++ .../test/integration/resolvers/helpers.ts | 6 -- .../resolver-parity-expected-failures.test.ts | 15 ++++ 13 files changed, 337 insertions(+), 28 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-collision/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-collision/base_lib.h create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-negative/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-negative/base_lib.h create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces/base_lib.h diff --git a/gitnexus/src/core/ingestion/languages/cpp/adl.ts b/gitnexus/src/core/ingestion/languages/cpp/adl.ts index bb28c3853..fd65ae51e 100644 --- a/gitnexus/src/core/ingestion/languages/cpp/adl.ts +++ b/gitnexus/src/core/ingestion/languages/cpp/adl.ts @@ -21,8 +21,9 @@ * - `audit::Event& r`, `audit::Event&& rr` * - `std::vector` (template namespace + template-arg namespaces) * - * Function-pointer arguments, base-class associated namespaces, and the rest - * of the full closure are still deliberately excluded. + * Function-pointer arguments and the rest of the full closure are still + * deliberately excluded.

Per ISO C++ `[basic.lookup.unqual]` §7, ADL is blocked only when ordinary lookup itself finds a non-function — if ordinary lookup stops at an inner scope where only callables exist, ADL should still fire. Replace the separate `hasNonCallableBindingInScope` + `findAllCallable BindingsInScope` calls with a combined `findCallableBindingsAndAdlBlocker` walker that stops at the first scope with ANY binding for the name and returns both `{ callables, nonCallableFound }`. One pass, one stop. Fixture: cpp-adl-inner-callable-outer-noncallable — inner scope has callable `swap(int,int)`, outer scope has `int swap = 0`. ADL fires and resolves to `data::swap(Pair&,Pair&)` via argTypes narrowing.

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