* fix(mcp): prevent orphan processes by handling stdin close/end and startup race condition
Three gaps in stdin EOF handling:
1. Startup race: parent can die before `process.stdin.on("end", ...)` is
registered, so the event is missed entirely.
2. Missing "close" event: when pipe is forcibly closed (parent SIGKILL),
"close" fires without "end" on some platforms.
3. Transport layer did not propagate stdin termination to its onclose
callback.
Fixes:
- Check readableEnded/destroyed in start() before registering listeners.
- Register stdin end+close listeners in CompatibleStdioServerTransport.
- Add _closed guard for idempotent close().
- Throw if start() is called after close().
- Add process.stdin.on("close") in server.ts alongside existing handlers.
- Add 5 regression tests.
* fix(mcp): register stdin shutdown before server connect
* feat(review): add PR reviewer swarm agents
Seven read-only subagents coordinated by an orchestration skill for
structured, evidence-grounded production-readiness PR reviews.
Agents: facts-historian, branch-hygiene, risk-architect, test-ci-verifier,
security-boundary, docs-dod, synthesis-critic. All use Read/Grep/Glob/Bash
only — no edit tools.
Skill invoked as /gitnexus-pr-swarm-review <PR>.
* fix: patch vector extension and uncaughtException for review findings
- Add { policy: 'auto' } to both loadVectorExtension() calls in
embedding-pipeline.ts so analyze --embeddings auto-installs VECTOR
- Add void to uncaughtException shutdown(1) call for Node v20+ safety
- Re-add getExtensionInstallPolicy export + default change + 4 tests
* fix(mcp,lbug): graceful shutdown exit codes + complete offline-first VECTOR policy
Completes the two live issues PR #1161 only partially addressed.
#1132 — MCP shutdown crash: SIGINT/SIGTERM were registered with `shutdown`
directly, so Node passed the signal NAME string into process.exit(), crashing
with ERR_INVALID_ARG_TYPE ('SIGTERM'). Map signals to numeric exit codes
(SIGINT->130, SIGTERM->143) via a testable installSignalShutdown(); add an
unref'd force-exit watchdog so a hung disconnect()/close() cannot wedge
shutdown; and void the stdin/stdout handlers so event payloads never reach
process.exit() as a non-number.
#1153 — offline-first extension loading:
- semanticSearch (a query/read path) no longer forces policy:'auto'; queries
use load-only and never spawn a network INSTALL (extension.ladybugdb.com).
- the analyze embedding WRITE path resolves the policy from
GITNEXUS_LBUG_EXTENSION_INSTALL (honoring never/load-only/auto; default auto)
instead of hard-forcing 'auto', so an offline/locked-down operator's override
is respected (the regression that re-broke #1153 for the VECTOR path).
- surface the active install policy in `gitnexus doctor` (was claimed but never
delivered; also gives the previously-dead getExtensionInstallPolicy a caller).
- emit an actionable message when VECTOR is unavailable.
Tests: regression for the signal->numeric mapping (reproduces the signal-string
crash condition) and for embedding install-policy resolution. tsc/prettier clean,
eslint 0 errors, 55 unit tests pass.

* fix(analyze): degrade gracefully when FTS extension is unavailable
The load-only default made `gitnexus analyze` throw when the FTS
extension was not pre-installed, breaking CI and offline use. Make the
analyze write path opt into the `auto` install policy (LOAD-first then
bounded INSTALL — symmetric with the VECTOR/embeddings path and the #726
contract) and degrade gracefully when the extension still cannot load:
skip search-index creation, log a warning, and complete with a fully
queryable graph (only full-text/BM25 search is disabled). `--repair-fts`
still fails loudly.
- Surface the degraded state instead of reporting healthy:
AnalyzeResult.ftsSkipped, a persistent CLI summary warning, and
meta.json capabilities.fts.status = "unavailable".
- Skip the FTS-primitive integration tests when the extension is
unavailable (shared skipUnlessFtsAvailable helper).
- Add a unit test for the degradation branch; fix the existing
full-analyze test mock that omitted loadFTSExtension.

* test(lbug): skip FTS-seeding suites when extension is unavailable
The withTestLbugDB helper seeds FTS indexes in beforeAll via createFTSIndex,
which throws when the optional FTS extension cannot load — failing the whole
suite on machines where it is neither pre-installed nor installable (the
macOS platform-sensitive CI runner). Probe the extension once (mirroring the
analyze write path's `auto` policy), bypass FTS seeding when it is
unavailable, and skip the suite's tests via beforeEach with a one-time
warning so the skip is visible rather than a setup crash.
Fixes the macOS failures in search-core, search-pool, local-backend-calltool,
and staleness-and-stability. Suites still run normally where FTS is available.

* feat(mcp): add tool safety annotations
* test(mcp): address PR #1127 review follow-ups
- Replace private `_requestHandlers` SDK access in server.test.ts with
`Client` + `InMemoryTransport.createLinkedPair()` for the tools/list
annotation propagation test. The new path uses supported public APIs
and surfaces SDK changes loudly instead of silently degrading.
- Extract `OPEN_WORLD_READ_ONLY_TOOLS` set in tools.test.ts so future
read-only open-world tools can be added without rewriting the
invariant; preserves the current "only `query` is open-world" guard.
- Add inline rationale on `group_sync` annotations explaining the
conservative `idempotentHint: false` (writes contracts.json on every
call even when output is deterministic).
No runtime behavior change. Annotations themselves and tools/list shape
are unchanged.

* feat: configure prettier with pre-commit hook integration
Add prettier, lint-staged, and prettier-plugin-tailwindcss at the repo
root with husky pre-commit hook integration. Moves husky from
gitnexus/ to root package.json for reliable hook installation.
- Root package.json with prepare/format/format:check scripts
- .prettierrc with endOfLine:lf and tailwindStylesheet for TW v4
- .prettierignore excluding fixtures, vendor, generated, *.d.ts, *.md
- .gitattributes enforcing LF line endings for Windows consistency
- Pre-commit hook uses direct node_modules/.bin/ paths (no npx)
* style: apply prettier formatting to entire codebase
One-time bulk format. No logic changes.
Use .git-blame-ignore-revs to skip this commit in git blame.
* chore: add .git-blame-ignore-revs for prettier format commit
* perf: pre-commit hook runs only tests related to staged files
Use vitest --related to scope test execution to tests that import
the changed files, instead of running the full suite on every commit.
* perf: remove vitest from pre-commit hook, keep in CI only
Pre-commit now runs lint-staged + tsc only. Tests run in CI
(ci-tests.yml) where they belong — keeps commits fast.
* ci: add prettier format check to quality workflow
PRs will now fail if code isn't formatted with prettier.
- 59 test files covering unit and integration tests
- vitest config with coverage thresholds and fork pooling
- Test fixtures (mini-repo + multi-language sample code)
- Add vitest + coverage-v8 to devDependencies
- Add test scripts (test, test:integration, test:all, test:watch, test:coverage)
- Move typescript to devDependencies where it belongs
