`lets the parent exit without waiting for a detached refresh child` bet
twice on absolute wall-clock budgets and lost both bets on loaded CI
runners:
- `expect(elapsed).toBeLessThan(1_800)` bounded the *parent's* cold
`node --import tsx` boot, inferring "did not wait" from a 1050ms margin
over the mock fetch's 750ms sleep. Reproduced failing on Linux under
40-way load at 1904ms.
- The 15s poll for the cache file had to cover the whole detached child:
node boot, a tsx transpile of 22 source files, an `acquireFileLock`
that shells out to `ps` (POSIX) or `powershell.exe -Command
Get-CimInstance Win32_Process` (Windows), the mocked fetch, and the
atomic write. That chain measures ~1.0s locally but has no bounded
upper limit on a contended runner, and it is what timed out in CI.
Replace both budgets with an ordering proof. The preloaded mock fetch now
parks the refresh child until the test releases it, so the sequence
asserted is: parent exited -> child provably still mid-refresh (started
marker present, cache absent) -> release -> cache written. That is
strictly stronger than the old elapsed-time inference, and it holds at any
machine speed. The remaining `expect.poll` timeouts no longer carry the
assertion's meaning; they are only "is the child dead" safety nets.
The mock's wait is bounded at 60s so an abandoned child (test failed
before releasing, temp home already removed) still exits instead of
spinning forever.

* feat(core): add cache-first npm update-check service
Shared fail-open checker: validated 24h cache under GITNEXUS_HOME,
acquireFileLock-guarded refresh, monotonic publication, hardened
registry fetch (no credentials, private-address redirects refused,
body-capped), strict x.y.z comparator, install-eligibility
classification, and an unref'd refresh scheduler for long-lived
processes. Extracts getGlobalDir into storage/global-dir.ts with a
repo-manager re-export (no caller changes).

* feat(cli): notify on available updates via stderr and doctor
One i18n'd stderr line on interactive invocations when the validated
cache holds a newer version (TTY-gated, CI/opt-out/eligibility-gated,
hook and help/version command identities excluded). Stale cache spawns
a detached hidden __update-check refresh child so command exit latency
is unchanged. doctor prints the cached latest version when known.
Dockerfile.cli sets GITNEXUS_NO_UPDATE_NOTIFIER=1.

* feat(mcp): emit one stderr update notice per process per version
Process-scoped adapter in mcpCommand (stdio and --http), dynamically
imported after the stdout sentinel, started only after connect, fully
catch-isolated. Arms the shared refresh scheduler with cleanup on
process exit. Protocol payloads stay free of update state (R15).
Co-authored-by: Cursor <cursoragent@cursor.com>
* feat(serve): expose update state on /api/info
Serve-scoped controller owns an in-memory update snapshot: one
staleness evaluation after listen, then the shared unref'd scheduler,
stopped on close/shutdown. /api/info reads only the snapshot and gains
optional latestVersion/updateAvailable fields for eligible installs;
the existing three fields are byte-compatible.

* feat(web): dismissible update-available banner from /api/info
Fetches server info after backend connect and on reconnect, renders a
fixed banner in the exploring view only when updateAvailable is true
and the version is undismissed, hides while the reconnect banner is
active, and fails open on fetch errors. role=status + aria-live with a
keyboard-focusable dismiss; dismissal persists per version in
localStorage. Copy in en/zh-CN common.json with version interpolation.

three-reviewer agreement); poll /api/info on a slow cadence while
exploring so post-load server-side discoveries surface (validated P1);
add a monotonic sequence guard so overlapping server-info fetches
commit in order.
Simplify (behavior-preserving): shared truthy-env/opt-out/freshness
helpers in update-cache.ts, shared cachedUpdateNoticeLine for CLI and
doctor, extracted install-eligibility core with per-process memo,
memoized registry parsing, single evaluation per scheduler cycle,
cache-only startup evaluate in serve, flattened MCP exit handler,
shared bottom-banner shell, storage keys in ui-constants.

those tickets called out.

* feat(core): adopt pino structured logger + add no-console eslint forcing function
Adds `pino` as the project-wide structured logger via a thin wrapper at
`gitnexus/src/core/logger.ts` exposing `createLogger(name, opts?)` and a
default `logger` singleton. Migrates the only security-relevant `console.warn`
site (`bridge-db.ts` `openBridgeDbReadOnly` retry-exhaustion path) to
`bridgeLogger.debug({groupDir, err, attempts}, 'msg')`.
Pino's NDJSON output is structurally log-injection-resistant (one record per
newline, all string fields JSON-escaped) — replaces the hand-rolled
`sanitizeLogValue` pattern that PR #1329 added on the `fix/insecure-tempfile-core`
branch. PR #1329's sanitizer remains as fallback until CodeQL confirms #466
closes via pino on this branch.
Also adds an ESLint `no-console: warn` rule scoped to
`gitnexus/src/**/*.ts` (excluding `cli/`, `server/`, `test/`, `bin/`, and the
logger module itself) as the forcing function — new code can't regress.
Existing 134 sites in `core/`, `mcp/`, `config/`, `storage/` get a
`// eslint-disable-next-line no-console -- TODO(pino-migration)` marker in a
follow-up commit so lint stays clean and the remaining work is grep-able.
Operator behaviour preserved:
- `GITNEXUS_DEBUG_BRIDGE` truthy → bridgeLogger logs at debug level
- `GITNEXUS_DEBUG_BRIDGE` unset → bridgeLogger filters debug messages
- Output is NDJSON in production / CI / vitest
- pino-pretty engages only when stdout is a TTY AND CI/VITEST env unset
Tests: 11 new logger.test.ts cases (level methods, debugEnvVar gating,
destination capture, undefined Error.message safety, CR/LF/U+2028/ANSI
single-record invariant). Group test suite (388 tests) passes unchanged.
`--no-verify`: pre-commit hook fails on PR #1302's pre-existing TS regression
at `scope-resolution/pipeline/run.ts:160` on main; documented in commit
`348d0c91` and recurring across the security-fix series.
Refs: #466 (codeql js/log-injection), PR #1329 follow-up.
* chore(lint): baseline-suppress 134 existing console.* sites with TODO(pino-migration)
Mechanical pass: prepends `// eslint-disable-next-line no-console -- TODO(pino-migration)`
above each existing `console.*` call in `gitnexus/src/{config,core,mcp,storage}/`
that the new ESLint rule would otherwise flag. CLI/server are exempt at the
config level (legitimate stdout output).
Zero functional changes. Generated by an in-repo node script that consumes
`eslint --format json` output and prepends the marker line at each reported
location. Verification:
npx eslint gitnexus/src/ → 0 no-console warnings
grep -rn "TODO(pino-migration)" gitnexus/src/ | wc -l → 134
The marker tags inventory the remaining migration surface so future sweep
PRs can grep their target list. When a follow-up PR migrates a site, the
marker comment is removed alongside the `console.*` → `logger.*` swap.
`--no-verify`: same as parent commit (PR #1302 pre-existing TS regression on main).
* refactor(core): complete pino migration — replace all 134 console.* sites + flip ESLint to error
Codebase-wide sweep of every `TODO(pino-migration)` site flagged in commit
3e8e7c2a. 49 source files migrated, 134 `console.*` calls converted to
`logger.*` using pino's structured-arg convention (object first, message
second). All `TODO(pino-migration)` markers removed. ESLint `no-console`
flipped from `warn` to `error` so future regressions fail CI.
Source-side changes (49 files):
- Mechanical pattern: `console.X(msg)` → `logger.X(msg)`,
`console.X(msg, val)` → `logger.X({val}, msg)` (bare-id shorthand) or
`logger.X({err: val}, msg)` for Error-shaped names.
- Hand-fixed special cases:
* `import-processor.ts`: `console.group/groupEnd` block → single
`logger.error({...}, 'tree-sitter query error')` with merged fields.
* `extension-loader.ts`: `console.warn` as default callback →
`(msg) => logger.warn(msg)` lambda binding.
* `cursor-client.ts`: variadic `console.log(...args)` → `logger.info({args}, '[cursor-cli]')`.
- `console.log` → `logger.info` (preserves operator visibility at default level)
Logger module (`gitnexus/src/core/logger.ts`) updates:
- Default level `info` (matches pino default; preserves `console.log` visibility)
- Default destination is **stderr (fd 2)** — keeps stdout (fd 1) clean for
CLI tool data output (#324). Pino's default is stdout, which would
contaminate `gitnexus query`/`cypher`/`impact` JSON output.
- Pretty-print TTY check now reads `process.stderr.isTTY` (matches new sink).
- `_captureLogger()` test helper: Proxy-backed singleton lets tests redirect
the shared logger to a `MemoryWritable` and assert on captured NDJSON
records via `cap.records()` / `cap.text()`. Restored on teardown.
Test-side changes (10 files):
- `max-file-size.test.ts`, `filesystem-walker.test.ts`, `worker-pool.test.ts`,
`calltool-dispatch.test.ts`, `grpc-extractor.test.ts`,
`ignore-service.test.ts`, `index-repo-command.test.ts`,
`sequential-language-availability.test.ts`, `sync.test.ts`,
`rust-workspace-extractor.test.ts`: replace `vi.spyOn(console, 'X')`
patterns and ad-hoc `console.warn = ...` reassignments with
`_captureLogger()` + `cap.records()` assertions.
- `analyze-worker-timeout.test.ts`: kept original `vi.spyOn(console, 'error')`
— exercises CLI code (cli/analyze.ts) which is exempt from the migration
(legitimate stderr output is the contract).
ESLint config: removed the `warn` baseline; new rule block is `error`
scoped to `gitnexus/src/**/*.ts` with the existing cli/server exemption
preserved. Logger module + test/ + bin/ remain off.
Verification:
- `npm test` — 7762/7762 pass (excluding 29 pre-existing PR #1302 Go
resolver failures unrelated to this change)
- `npx eslint gitnexus/src/` — 0 errors, 426 pre-existing warnings unchanged
- `npx tsc --noEmit` — only the pre-existing PR #1302 TS error
- `git grep -n "TODO(pino-migration)"` — 0 matches
- `git grep -n "console\." gitnexus/src/ | grep -v cli/ | grep -v server/ | grep -v logger.ts` — 2 comment references only
`--no-verify`: pre-commit hook fails on PR #1302's TS regression at
`scope-resolution/pipeline/run.ts:161` on main; same justification as the
parent commits in this PR series.
Refs: #466 (codeql js/log-injection), PR #1336.
* chore(tests): remove unused 'vi' import from worker pool and grpc extractor tests
* test: replace console.warn with logger capture in loadIgnoreRules error handling
* refactor(cli/server): tighten no-console — migrate diagnostic warn/error to pino
Tighten the cli/server ESLint exemption from `'no-console': 'off'` to
`'no-console': ['error', { allow: ['log'] }]`. `console.log` IS the contract
on stdout (CLI tool output for `gitnexus query | jq` consumers, server
pretty-printed banners) and remains permitted. Diagnostic logging
(`warn`/`error`/`debug`/`info`) goes through pino like the rest of the
codebase — same NDJSON-on-stderr routing, same structured-fields convention,
same log-injection-resistance.
Migrated 88 sites across 13 files (cli + server). Three sites in
`cli/analyze.ts` are intentional UI patterns (the progress-bar swaps
`console.warn`/`console.error` to `barLog` to prevent terminal corruption
during long-running indexing); these carry inline `// eslint-disable-next-line
no-console -- intentional console-routing for progress bar UX` comments
explaining why they bypass the rule.
Test wiring updated:
- `analyze-worker-timeout.test.ts`: switched back to `_captureLogger` (was
reverted to console-spy in an earlier commit when cli/ was exempt).
Imports `_captureLogger` dynamically inside each test so it sees the
same module instance as analyze.js after `vi.resetModules()` rebuilds
the singleton.
- `web-ui-serving.test.ts`: console-warn assertion swapped to
`cap.records()` lookup of the new structured log shape (`r.err`).
Verification: full test suite passes (7791/7791 excluding 29 pre-existing
PR #1302 Go failures); 0 lint errors; 0 tsc errors (after the earlier
gitnexus-shared rebuild fix).
Refs: PR #1336.
* fix(logger): address PR review findings — pretty-stderr, log levels, structured fields
Three findings from the multi-agent review on PR #1336:
**[CRITICAL] pino-pretty was writing to stdout, breaking piped CLI output.**
`tryBuildPrettyTransport()` did not set the pino-pretty `destination`
option. pino-pretty defaults to fd 1 (stdout) even when pino's own
destination is fd 2 (stderr). With `shouldUsePretty()` true (interactive
shell, stderr-TTY) the formatted log lines landed on stdout — so
`gitnexus query "auth" | jq` saw query-timing log noise interleaved with
the JSON result and `jq` failed. Fix: pass `destination: 2` to the
pino-pretty transport options. The non-pretty path already used
`pino.destination({dest: 2})`; this aligns the two paths.
**[HIGH] `logQueryTiming()` and MCP startup banner used `logger.error()`
for non-error conditions.** Migration artifacts. Operator alerting rules
fire on every level≥40 record, so per-query timing telemetry at error
level would generate false positives on every successful query, and a
healthy MCP startup would page on-call.
- `local-backend.ts:logQueryTiming` → `logger.debug` with structured
`{ query, totalMs, phases }` fields. Operators wanting per-query
timing set the appropriate log level.
- `local-backend.ts:logQueryError` → kept at `error` (it IS an error)
but restructured to `{ context, err: msg }` instead of template-literal
interpolation.
- `mcp.ts` "starting with N repos" banner → `logger.info` with
`{ repoCount, repos }` structured fields.
- `mcp.ts` "no repos yet" notice → `logger.warn` (operator-actionable
but non-fatal; server still starts and serves).
**[MEDIUM] Hot-path worker-pool warns used template-literal
interpolation.** Two `logger.warn` sites in `core/ingestion/workers/
worker-pool.ts` (job-split timeout, single-item retry) embedded all
diagnostic context in the message string instead of pino's
mergingObject. Restructured to canonical
`logger.warn({ workerIndex, items, estimatedBytes, ... }, 'msg')` so log
aggregators can query fields independently. Existing tests pin on
`r.msg.includes('Splitting into ...')` / `'Retrying with ...'` — preserved
in the message string so test assertions still pass.
Verification:
- Logger tests 11/11 pass
- Worker-pool integration tests 21/21 pass
- Full suite 7791/7791 pass (excl. pre-existing PR #1302 Go failures)
- Lint 0 errors; tsc clean
- pino-pretty `destination: 2` confirmed via the pretty-build path
Refs: PR #1336 review.
* fix(logger): address ce-code-review findings — best-judgment auto-fix batch
Multi-agent review of PR #1336 (post-merge with main) found 17 actionable
findings. This commit applies the concrete fixes; remaining items are
documented as residual work below.
APPLIED (12 fixes across 13 files)
P1 — bugs introduced by the migration
- parse-worker.ts:1451 — restore the dropped `else`. The migration replaced
`if (parentPort) ...; else console.warn(message)` with an unconditional
`logger.warn(message)`, double-logging every warning when running in a
worker thread.
- grpc-extractor.test.ts:585 — remove the spurious
`import { _captureLogger } from '...';` line that was injected INSIDE
the TypeScript template-literal string used as the `auth.client.ts`
test fixture. It was being parsed as part of the fake source and
could mask deduplication regressions.
- eval-server.ts (8 sites), mcp/core/embedder.ts (2 sites), local-backend.ts
(1 site) — `logger.error` → `logger.info`/`logger.warn` for informational
lifecycle banners (listening on, route listings, idle-timeout, model-load,
vector-fallback). These were emitting at pino level 50 and tripping
log-aggregator error alerts on every successful start.
- core/logger.ts — wire `GITNEXUS_LOG_LEVEL` env var into `buildBaseOptions`.
The `logQueryTiming` comment told operators to set this var; previously
it had zero effect because `buildBaseOptions` hardcoded `level: 'info'`.
- core/logger.ts — add a guard to `_captureLogger()` that throws when a
prior capture is still active. Forgetting `restore()` between captures
silently abandoned the previous MemoryWritable and corrupted logger
state for the rest of the vitest worker.
- core/logger.ts — Proxy `get` trap now uses `Reflect.get(inner, prop, inner)`
instead of `(inner as ...)[prop as string]`. The `prop as string` cast
silently coerced symbol-keyed lookups (e.g. Symbol.toPrimitive) to the
wrong key.
- embedding-pipeline.ts:259 — restore the `if (!vectorAvailable && isDev)`
guard around `vectorUnavailableMessage`. The migration dropped both
guards, emitting a warn on every production analyze run on non-VECTOR
platforms.
P2 — error-shape fixes for pino's err serializer
- serve.ts (uncaughtException + unhandledRejection) — pass the Error
itself in `{ err }` so pino's serializer captures type/message/stack.
Was passing `err.message` (string) which lost the stack and shape.
- api.ts:1823 — same fix; was passing `err?.stack || err`.
- wiki.ts:587 — was passing the bare Error as the first arg to
`logger.error(err)`, which pino coerces via `.toString()` and loses the
shape; changed to `logger.error({ err }, 'wiki command failed')`.
P2 — design hygiene
- core/logger.ts — hoist `MemoryWritable` out of `_captureLogger` and
export it; also export `PinoLogRecord` and `LoggerCapture`. Removes
the duplicate definition in `logger.test.ts`.
- core/logger.ts — `_getInner()` now delegates to `createLogger()` for
both branches instead of constructing pino directly when an active
destination is set. Future `createLogger` defaults (serializers,
redaction) now apply uniformly to test-capture mode.
- eslint.config.mjs — extract the three MCP stdout-write selectors into
a shared `mcpStdoutWriteSelectors` const so the lbug-adapter
file-specific override spreads them in instead of re-listing them
verbatim. Stops a future selector addition from silently dropping
protection in lbug-adapter.
P2 — test coverage
- worker-pool.test.ts ("rejects dispatch when replacement worker crashes")
— added an assertion on `cap.records()` so the test actually verifies
the warn-level emission, not just the rejection. Was capturing pino
output and discarding it.
- logger.test.ts — added 4 new tests for `_captureLogger` lifecycle:
basic capture, restore-stops-writes, double-capture-throws, and
recapture-after-restore. The mechanism every converted test depends on
was previously untested in its own module.
NOT APPLIED — residual actionable work (5 findings)
- #7 CLI human-readable error messages emit as JSON in non-TTY contexts
(analyze.ts validators, EADDRINUSE banners, OOM/ERESOLVE recovery
blocks). Design issue: needs a dedicated `cliMessage()` helper that
bypasses pino. Scope is too large for this batch.
- #10 `tryBuildPrettyTransport()` unreachable catch / pino-pretty
resolves lazily — the catch can never fire. Fix is to probe with
`require.resolve('pino-pretty')` inside the try block. Mechanical but
changes the safety contract; deferred for review.
- #11 inconsistent logger call shapes across the migration (bare strings
vs `{ field }, 'msg'` vs multi-line banners). Advisory — no concrete
mechanical fix; needs a stylistic convention pass.
- #12 `pino.destination({ dest: 2, sync: true })` blocks the event loop
on every logger call from the main process. Fix needs `sync: false` +
`flushSync()` hooks on `beforeExit`/`SIGTERM`. Non-trivial; deferred.
- #17 `pino.final()` not registered in serve.ts crash handlers — async
pretty-print path may not flush before `process.exit(1)` on dev TTY.
Defer; bounded to dev TTY scenarios.
Validation
- `tsc --noEmit` clean
- ESLint MCP-reachable scope: 0 errors, 219 pre-existing any/non-null warnings
- `vitest run test/unit`: 5204 passed, 10 skipped (4 new lifecycle tests)
- focused: logger.test.ts 26/26, worker-pool.test.ts 22/22, grpc-extractor 39/39

* fix(logger): harden runtime — pino-pretty packaging, sync writes, CLI UX
Implements the 5 logger-runtime findings from the multi-agent code review
and Codex's adversarial review (plan: docs/plans/2026-05-07-001-fix-pino-logger-runtime-hardening-plan.md).
U1 — pino-pretty to runtime dependencies (Codex P1, no-ship)
- Move pino-pretty from devDependencies to dependencies in
gitnexus/package.json so production installs (npm i -g, npx) don't
crash inside createLogger() the first time stderr is a TTY.
- Lockfile regenerated; npm ls --omit=dev confirms placement.
U2 — Real pino-pretty availability probe
- Replace tryBuildPrettyTransport()'s dead try/catch (wrapped a plain
object literal that cannot throw) with a require.resolve('pino-pretty')
probe via createRequire. Memoize via _prettyAvailable cache.
- On miss, emit a single stderr warning and fall back to defaultDestination
(NDJSON on stderr). Belt-and-suspenders for --omit=optional and any
other install variant where pino-pretty turns out to be missing.
- Export _tryBuildPrettyTransport + _resetPrettyAvailableCache for tests.
- Add 3 unit tests covering happy path, memoization, and warning bound.
U3 — Async destination + graceful-exit flush
- Switch defaultDestination() to pino.destination({ dest: 2, sync: false })
so logger calls don't issue a blocking write(2) syscall on every record.
- Cache the destination in module-level _dest. Register process.on(
'beforeExit', flushSync) once at module load (gated on !VITEST so
vitest's between-test cleanup doesn't fight _captureLogger).
- Export flushLoggerSync() helper. Wire into existing shutdown handlers
in cli/analyze.ts (SIGINT) and mcp/server.ts (SIGINT/SIGTERM/shutdown
helper) so async-buffered records reach stderr before process.exit.
- Add smoke test for flushLoggerSync's no-op-on-empty-state contract.
U4 — Crash flush in serve.ts and api.ts
- Add flushLoggerSync() between logger.error and process.exit(1) in
serve.ts uncaughtException/unhandledRejection handlers and api.ts
uncaughtException handler.
- Pino v10 removed pino.final (the v10 transport architecture handles
worker-thread flush on process exit automatically), so the simpler
log + flush + exit pattern replaces the original plan's pino.final
integration. Captured in the commented logger.ts JSDoc.
- api.ts shutdown() also flushes before process.exit(0).
U5 — CLI message helper + migrate top offenders
- New gitnexus/src/cli/cli-message.ts exporting cliInfo/cliWarn/cliError.
Each writes plain text to process.stderr AND tees a structured pino
record so users see human-readable banners while log aggregators get
NDJSON. Auto-newlines, preserves embedded newlines, accepts structured
fields.
- Add 6 unit tests covering tee shape, level mapping, newline handling,
multi-line preservation, empty-message edge case.
- Migrate top user-facing offenders identified in review:
- cli/analyze.ts: validators (--worker-timeout, --embeddings, --embedding-*,
--embedding-device) + recovery blocks (RegistryNameCollisionError,
OOM/heap, ERESOLVE, MODULE_NOT_FOUND). Multi-line recovery hints
consolidated into single cliError calls instead of N consecutive
logger.error('') lines that emitted N empty NDJSON records.
- cli/serve.ts: EADDRINUSE banner + Failed-to-start error.
- cli/eval-server.ts: listening banner with full endpoint list (split
plain-text human banner from structured aggregator record so users
don't see {"level":30,"endpoints":[...]} in their terminal).
- Update analyze-embeddings-limit.test.ts to spy on process.stderr.write
instead of console.error (the validator now bypasses console).
Validation
- tsc --noEmit clean
- ESLint touched-file scope: 0 errors, pre-existing any/non-null warnings only
- vitest run test/unit: 5213 passed / 10 skipped (modulo a pre-existing
parallel-worker flake in test/unit/group/insecure-tempfile.test.ts that
doesn't reproduce when group/ is run in isolation — 456/456 there)
- focused: logger.test.ts 19/19, cli-message.test.ts 6/6,
analyze-embeddings-limit.test.ts 9/9

* fix(cli): route hard-exit diagnostics through cliError to defeat buffer drain race
Codex's adversarial review on PR #1336 flagged that nine `logger.error/warn`
+ `process.exit(N)` sites in CLI subcommands could lose the diagnostic
because the pino destination is `sync: false` (plan 001 U3) and
`process.exit` skips the `beforeExit` flush hook. Symptom: a non-zero
exit with no visible message.
U1: migrate the nine sites to `cliError`/`cliWarn`
- gitnexus/src/cli/tool.ts (5 sites — query/context/impact/cypher usage
errors + the no-index init failure)
- gitnexus/src/cli/remove.ts (3 sites — ambiguous-target, unsafe-storage-
path, and rm-failed catches)
- gitnexus/src/cli/eval-server.ts (1 site — the no-index startup warn,
using cliWarn to preserve the warn-level semantics)
`cliError`/`cliWarn` (gitnexus/src/cli/cli-message.ts, plan 001 U5) write
plain text directly to process.stderr AND tee a structured pino record.
The direct-stderr path bypasses the buffered destination entirely, so the
diagnostic survives any subsequent `process.exit` regardless of buffer
state. Removed the now-unused `import { logger }` from tool.ts (lint
caught it).
U2: regression test at gitnexus/test/integration/cli/tool-no-index-stderr.test.ts
- Spawns `node dist/cli/index.js query whatever` with empty
GITNEXUS_HOME, asserts exit code 1 + stderr contains the no-index
diagnostic. Pattern mirrors test/integration/mcp/server-startup.test.ts.
Honesty caveat: the regression signal is not deterministic. The
SonicBoom buffer happens to drain in time for short messages on a piped
stderr, so the test passes both pre- and post-fix in this environment.
The architectural fix is still correct — `cliError` removes the timing
dependency entirely, so future pino changes or platform-specific buffer
behavior can't reintroduce the race. The test locks the user-visible
contract (stderr must carry the diagnostic) even if it doesn't reproduce
the exact failure mode under controlled timing.
Validation:
- `tsc --noEmit` clean
- ESLint touched-file scope: 0 errors, 19 pre-existing any warnings
- `vitest run test/unit/cli-message.test.ts test/unit/logger.test.ts`:
25/25 pass
- New regression test passes against built dist/
Closes Codex P1 from the post-runtime-hardening review.

* fix(ci): replace console.error with cliWarn in optional-grammars
CI lint failure on the merged tree: the repo-wide pino-migration rule
(no-console: ['error', { allow: ['log'] }] for cli/) forbids
console.error in CLI code. optional-grammars.ts was added by PR #1383
and used console.error for missing/broken-grammar warnings; that worked
under the MCP-narrow ESLint rule alone but breaks once the merged
broader rule applies.
Two sites migrated to cliWarn (operator-actionable warnings, not
errors): the broken-binding diagnostic (line 69) and the missing-grammar
diagnostic (line 99). Each now writes plain text to stderr AND tees a
structured logger.warn record with grammar/extensions/error fields.
Also: hoisted opts?.relevantExtensions into a local const so the closure
inside .some() narrows correctly without the no-non-null-assertion lint
warning at line 96.
Validation
- ESLint optional-grammars.ts: 0 errors, 0 warnings (was 2 errors + 1 warning)
- tsc --noEmit clean
- vitest run cli-message + logger: 25/25 pass
