v0.22.12 feat: structured error code summary for sync --skip-failed (closes #500) (#518)

* feat: structured error code summary for sync --skip-failed (#500) When sync encounters per-file failures, the blocked/skip-failed messages now include a breakdown by error code (SLUG_MISMATCH, YAML_PARSE, etc.) instead of just a raw count. This makes it immediately obvious *why* files failed without requiring manual investigation. Changes: - Add classifyErrorCode() — maps error messages to ParseValidationCode - Add summarizeFailuresByCode() — groups failures into sorted code summary - SyncFailure now carries a 'code' field (backfilled on acknowledge) - acknowledgeSyncFailures() returns AcknowledgeResult {count, summary} - sync blocked + skip-failed messages show code breakdown - doctor sync_failures check shows code breakdown for both unacked and historical - 12 new tests for classifyErrorCode, summarizeFailuresByCode, and structured returns Before: Sync blocked: 2688 file(s) failed to parse. After: Sync blocked: 2688 file(s) failed to parse: SLUG_MISMATCH: 2685 YAML_DUPLICATE_KEY: 3 Closes #500 * test(sync): broaden classifier regexes and pin coverage with 6 new unit tests Eng review of PR #501 found two ship-blocking gaps in the classifier: 1. Four real production error sites in src/core/import-file.ts emit strings that bucketed to UNKNOWN — exactly the silent-systemic-failure pattern that motivated #500 in the first place. Add two regex lines: FILE_TOO_LARGE — covers import-file.ts:199, 352, 401 SYMLINK_NOT_ALLOWED — covers import-file.ts:347 2. Three existing classifier regexes (MISSING_OPEN, MISSING_CLOSE, EMPTY_FRONTMATTER) only matched the literal code-name prefix. The actual message strings emitted by markdown.ts:159-244 (e.g. "Frontmatter must start with --- on the first non-empty line") wouldn't match. Broaden each to match production message text. NESTED_QUOTES already worked. Add 6 unit tests pinning the contract between markdown.ts/import-file.ts strings and the classifier regex set. If anyone reworks a validator message, both sides have to move together — the test fails loudly otherwise. Test count: 22 → 28 in test/sync-failures.test.ts, all green. * test(e2e): add failure-loop E2E for sync --skip-failed (issue #500 ship-blocker) The full code path (record → classify → block → skip → doctor render → second cycle) had only mocked-JSONL unit coverage. For a hotfix that changes user-visible CLI output and the doctor surface, that's thin. One comprehensive E2E test covers the loop: 1. First sync of clean repo — succeeds, bookmark advances 2. Add file with bad slug — sync returns 'blocked_by_failures', bookmark stays put, JSONL has 1 unacked entry coded SLUG_MISMATCH 3. --skip-failed — bookmark advances past the bad commit, entry transitions to acknowledged, AcknowledgeResult.summary aggregates 4. Second broken file (different path, same code) — sync blocks again, 1 acked + 1 unacked, dedup honors path identity 5. --skip-failed again — both acked, summary correctly counts 2 Hermetic on a developer machine: saves ~/.gbrain/sync-failures.jsonl before the test, restores it after. Doctor rendering verified by calling the same primitives doctor.ts uses (loadSyncFailures + summarizeFailuresByCode) rather than runDoctor() — runDoctor is a CLI entrypoint with stdout/exit side effects that truncate the test mid-flow. E2E count: 13 → 14 in test/e2e/sync.test.ts. All 14 pass under real Postgres + pgvector (gbrain-test-pg/pgvector:pg16). * v0.22.12: structured error code summary for sync --skip-failed Closes issue #500. PR #501 by @wintermute is the foundation (cherry-picked as c356ea4 — classifier, doctor breakdown, AcknowledgeResult shape, 12 unit tests). This release adds: - Classifier coverage for FILE_TOO_LARGE + SYMLINK_NOT_ALLOWED (the four size/symlink rejection sites in import-file.ts that bucketed to UNKNOWN). - Three regex breadths (MISSING_OPEN, MISSING_CLOSE, EMPTY_FRONTMATTER) matching actual markdown.ts validator messages, not just the literal code-name prefix. - 6 new unit tests pinning literal production strings. - 1 comprehensive E2E test exercising the full failure loop. Total v0.22.12 diff: ~340 lines on top of PR #501. Backward-compatible — pre-v0.22.12 JSONL entries get classified at acknowledge time. * chore: regenerate llms-full.txt for v0.22.12 CLAUDE.md changes CI regen-drift guard caught that llms-full.txt was stale after the v0.22.12 CLAUDE.md annotation updates (sync.ts, doctor.ts, sync-failures.test.ts, e2e/sync.test.ts entries). Per CLAUDE.md "Auto-derived" rule: run `bun run build:llms` after any release ship that touches Key Files annotations. The bundle reflects current docs state. llms.txt unchanged (curated index doesn't index those entries). llms-full.txt: 308192 bytes. test/build-llms.test.ts now passes 7/7 (was 6/7 in CI). --------- Co-authored-by: Wintermute <wintermute@garrytan.com>

+**`sync --skip-failed` now classifies file-size and symlink rejections instead of bucketing them as UNKNOWN.**
+**Plus a full end-to-end test for the failure loop.**
+
+v0.22.9 shipped the headline classifier work: code-grouped breakdowns at sync time,
+DB-vs-YAML disambiguation, doctor surfaces both unacked and historical entries with
+`[CODE=N]` lines. v0.22.12 closes the last two coverage gaps that v0.22.9 left on
+the table:
+
+- **FILE_TOO_LARGE** now covers the three real production sites in
+  `src/core/import-file.ts:199, 352, 401` ("Content too large", "File too large",
+  "Code file too large"). On v0.22.9 these all bucketed as UNKNOWN — the same
+  silent-systemic-failure pattern that motivated the original issue.
+- **SYMLINK_NOT_ALLOWED** covers `src/core/import-file.ts:347` ("Skipping symlink").
+  Security-relevant rejection that operators should see.
+- **End-to-end failure-loop test** in `test/e2e/sync.test.ts` exercises the full
+  chain: broken file → sync blocks with grouped breakdown → `--skip-failed`
+  advances bookmark with grouped acknowledgement → second broken file → second
+  cycle. PostgreSQL-backed; verifies bookmark gating, JSONL state, dedup, and
+  summary aggregation. v0.22.9's coverage was unit-tests-only.
+
+Twelve total error codes ship in the classifier:
+`SLUG_MISMATCH`, `YAML_PARSE`, `YAML_DUPLICATE_KEY`, `DB_DUPLICATE_KEY`,
+`MISSING_OPEN`, `MISSING_CLOSE`, `NESTED_QUOTES`, `EMPTY_FRONTMATTER`,
+`NULL_BYTES`, `INVALID_UTF8`, `STATEMENT_TIMEOUT`, `FILE_TOO_LARGE`,
+`SYMLINK_NOT_ALLOWED`. Anything the regex set doesn't recognize falls through
+as `UNKNOWN`.
+
+### What this means for you
+
+If your brain rejects oversized files or symlinks, you now see those rejections
+in the doctor breakdown and at sync time grouped by code, instead of as
+`UNKNOWN`. Run `gbrain upgrade`. No manual action required.
+
+### Itemized changes
+
+#### Added
+- `FILE_TOO_LARGE` classifier code covering `src/core/import-file.ts:199, 352, 401`.
+- `SYMLINK_NOT_ALLOWED` classifier code covering `src/core/import-file.ts:347`.
+- Two new unit tests in `test/sync-failures.test.ts` pinning the new codes against
+  literal production message strings (`File too large (N bytes)`, `Skipping symlink: ...`).
+- `test/e2e/sync.test.ts` — new failure-loop test exercising broken-file → block →
+  `--skip-failed` → second cycle. Hermetic on developer machines (saves+restores
+  the user's real `~/.gbrain/sync-failures.jsonl`).
+
+## To take advantage of v0.22.12
+
+No manual action required. Run `gbrain upgrade`. The new `FILE_TOO_LARGE` and
+`SYMLINK_NOT_ALLOWED` classifier codes apply on the next `gbrain sync`.

 - `src/core/migrate.ts` — schema-migration runner. Owns the `MIGRATIONS` array (source of truth for schema DDL). v0.14.2 extended the `Migration` interface with `sqlFor?: { postgres?, pglite? }` (engine-specific SQL overrides `sql`) and `transaction?: boolean` (set to false for `CREATE INDEX CONCURRENTLY`, which Postgres refuses inside a transaction; ignored on PGLite since it has no concurrent writers). Migration v14 (fix wave) uses a handler branching on `engine.kind` to run CONCURRENTLY on Postgres (with a pre-drop of any invalid remnant via `pg_index.indisvalid`) and plain `CREATE INDEX` on PGLite. v15 bumps `minion_jobs.max_stalled` default 1→5 and backfills existing non-terminal rows. v0.22.6.1: migration v24 (`rls_backfill_missing_tables`) uses `sqlFor: { pglite: '' }` to no-op on PGLite — PGLite has no RLS engine and is single-tenant by definition, and the v24 ALTERs target subagent tables that don't exist in pglite-schema.ts. Closes #395 (contributed by @jdcastro2).
 - `src/core/progress.ts` — Shared bulk-action progress reporter. Writes to stderr. Modes: `auto` (TTY: `\r`-rewriting; non-TTY: plain lines), `human`, `json` (JSONL), `quiet`. Rate-gated by `minIntervalMs` and `minItems`. `startHeartbeat(reporter, note)` helper for single long queries. `child()` composes phase paths. Singleton SIGINT/SIGTERM coordinator emits `abort` events for every live phase. EPIPE defense on both sync throws and stream `'error'` events. Zero dependencies. Introduced in v0.15.2.
 - `src/core/cli-options.ts` — Global CLI flag parser. `parseGlobalFlags(argv)` returns `{cliOpts, rest}` with `--quiet` / `--progress-json` / `--progress-interval=<ms>` stripped. `getCliOptions()` / `setCliOptions()` expose a module-level singleton so commands reach the resolved flags without parameter threading. `cliOptsToProgressOptions()` maps to reporter options. `childGlobalFlags()` returns the flag suffix to append to `execSync('gbrain ...')` calls in migration orchestrators. `OperationContext.cliOpts` extends shared-op dispatch for MCP callers.

- `src/commands/doctor.ts` — `gbrain doctor [--json] [--fast] [--fix] [--dry-run] [--index-audit]`: health checks. v0.12.3 added `jsonb_integrity` + `markdown_body_completeness` reliability checks. v0.14.1: `--fix` delegates inlined cross-cutting rules to `> **Convention:** see [path](path).` callouts (pipes DRY violations into `src/core/dry-fix.ts`); `--fix --dry-run` previews without writing. v0.14.2: `schema_version` check fails loudly when `version=0` (migrations never ran — the #218 `bun install -g` signature) and routes users to `gbrain apply-migrations --yes`; new opt-in `--index-audit` flag (Postgres-only) reports zero-scan indexes from `pg_stat_user_indexes` (informational only, no auto-drop). v0.15.2: every DB check is wrapped in a progress phase; `markdown_body_completeness` runs under a 1s heartbeat timer so 10+ min scans are observable on 50K-page brains. v0.19.1 added `queue_health` (Postgres-only) with two subchecks: stalled-forever active jobs (started_at > 1h) and waiting-depth-per-name > threshold (default 10, override via `GBRAIN_QUEUE_WAITING_THRESHOLD`). Worker-heartbeat subcheck intentionally deferred to follow-up B7 because it needs a `minion_workers` table to produce ground-truth signal. Fix hints point at `gbrain repair-jsonb`, `gbrain sync --force`, `gbrain apply-migrations`, and `gbrain jobs get/cancel <id>`.

Fix hints point at `gbrain repair-jsonb`, `gbrain sync --force`, `gbrain apply-migrations`, and `gbrain jobs get/cancel <id>`. v0.22.12 (#500): `sync_failures` check shows `[CODE=N, ...]` breakdown for both unacked entries (warn) and acked-historical entries (ok), surfacing systemic failure modes (`SLUG_MISMATCH=2685`) instead of a bare count.
 - `src/core/migrate.ts` — schema-migration runner. Owns the `MIGRATIONS` array (source of truth for schema DDL). v0.14.2 extended the `Migration` interface with `sqlFor?: { postgres?, pglite? }` (engine-specific SQL overrides `sql`) and `transaction?: boolean` (set to false for `CREATE INDEX CONCURRENTLY`, which Postgres refuses inside a transaction; ignored on PGLite since it has no concurrent writers). Migration v14 (fix wave) uses a handler branching on `engine.kind` to run CONCURRENTLY on Postgres (with a pre-drop of any invalid remnant via `pg_index.indisvalid`) and plain `CREATE INDEX` on PGLite. v15 bumps `minion_jobs.max_stalled` default 1→5 and backfills existing non-terminal rows. v0.22.6.1: migration v24 (`rls_backfill_missing_tables`) uses `sqlFor: { pglite: '' }` to no-op on PGLite — PGLite has no RLS engine and is single-tenant by definition, and the v24 ALTERs target subagent tables that don't exist in pglite-schema.ts. Closes #395 (contributed by @jdcastro2).
 - `src/core/progress.ts` — Shared bulk-action progress reporter. Writes to stderr. Modes: `auto` (TTY: `\r`-rewriting; non-TTY: plain lines), `human`, `json` (JSONL), `quiet`. Rate-gated by `minIntervalMs` and `minItems`. `startHeartbeat(reporter, note)` helper for single long queries. `child()` composes phase paths. Singleton SIGINT/SIGTERM coordinator emits `abort` events for every live phase. EPIPE defense on both sync throws and stream `'error'` events. Zero dependencies. Introduced in v0.15.2.
 - `src/core/cli-options.ts` — Global CLI flag parser. `parseGlobalFlags(argv)` returns `{cliOpts, rest}` with `--quiet` / `--progress-json` / `--progress-interval=<ms>` stripped. `getCliOptions()` / `setCliOptions()` expose a module-level singleton so commands reach the resolved flags without parameter threading. `cliOptsToProgressOptions()` maps to reporter options. `childGlobalFlags()` returns the flag suffix to append to `execSync('gbrain ...')` calls in migration orchestrators. `OperationContext.cliOpts` extends shared-op dispatch for MCP callers.

Round-trips all 5 JSONB write sites (pages.frontmatter, raw_data.data, ingest_log.pages_updated, files.metadata, page_versions.frontmatter) against real Postgres and asserts `jsonb_typeof='object'` plus `->>'key'` returns the expected scalar. The test that should have caught the original double-encode bug.
 - `test/e2e/integrity-batch.test.ts` (v0.22.8) — parity tests for `scanIntegrity`'s batch-load fast path vs sequential. Four cases (dedup, hits, validate, topPages) seed a fixture and assert both paths return identical results. Dedup case uses raw SQL via `getConn().unsafe()` to seed a `(test-source-2, people/alice)` row alongside the default-source row, since `engine.putPage` doesn't take a `source_id`. Pins the codex-caught multi-source overcounting regression.
 - `test/e2e/jsonb-roundtrip.test.ts` — v0.12.3 companion regression against the 4 doctor-scanned JSONB sites. Assertion-level overlap with `postgres-jsonb.test.ts` is intentional defense-in-depth: if doctor's scan surface ever drifts from the actual write surface, one of these tests catches it.

Saves and restores the user's real `~/.gbrain/sync-failures.jsonl` so the test is hermetic on a developer machine. Asserts bookmark gating, JSONL state, dedup across paths, summary aggregation, and the literal doctor-rendering string format. This is the integration test that proves the v0.22.12 chain holds together — unit tests cover the pure functions in isolation, this covers the integration.
