* feat(worker-pool): shared sliding pool + bounded semaphore + PGLite-clamp wrapper T1 + T2 of the v0.41.16.0 workers cathedral. New src/core/worker-pool.ts is the canonical primitive every --workers N bulk command in this wave (and future bulk commands) builds on. Atomic-claim invariant enforced by scripts/check-worker-pool-atomicity.sh (wired into bun run verify). BudgetExhausted bypass + AbortSignal composition baked into the helper so budget caps are a structural ceiling under concurrency, not a per-caller convention. The new resolveWorkersWithClamp wrapper composes existing autoConcurrency with PGLite-clamp + per-(command, requested) stderr dedup. Deliberately NOT a modification to shared autoConcurrency (silent today, used by sync + import); embed.ts keeps GBRAIN_EMBED_CONCURRENCY || 20 default per codex #13. 23 + 12 + 9 = 44 hermetic tests pin every contract. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test: structural + dim-check regression suites for v0.41.16.0 wave - test/embed-helper-migration.test.ts (T3): asserts embed.ts's two sliding-pool sites are migrated to runSlidingPool, pre-migration shapes (let nextIdx = 0, Promise.all(Array.from(...))) are gone, GBRAIN_EMBED_CONCURRENCY || 20 default preserved, failureLabel threads page.slug. Per codex #16/#17 these are invariant assertions, not byte-equality on progress event ORDERING. - test/embedding-dim-check-facts.test.ts (T6): readFactsEmbeddingDim covers vector(N) + halfvec(N), halfvec-before-vector regex ordering pinned (codex #19), buildFactsAlterRecipe emits DROP INDEX + ALTER USING + CREATE INDEX (codex #18, not bare REINDEX), FactsEmbeddingDimMismatchError tagged class shape, assertFactsEmbeddingDimMatchesConfig PGLite skip + Postgres absent- column skip, doctor check + insert-cast wiring assertions. - test/extract-conversation-facts-workers.test.ts (T5): helper exports (extractConversationFactsLockId, PER_PAGE_LOCK_TTL_MINUTES), structural wiring (runSlidingPool, resolveWorkersWithClamp, withRefreshingLock, LockUnavailableError, delete-orphans-first before segment loop, preflight before pool, exit 3 when lock_skipped > 0), Minion handler round-trip. - test/extract-workers.test.ts (T7): --workers wiring on all 3 inner fs-walk loops (extractForSlugs, extractLinksFromDir, extractTimelineFromDir) + CLI parse + opts threading through runExtractCore.

Advancing this wave to v0.41.17.0 so both can land cleanly. Pure mechanical version bump: - VERSION + package.json → 0.41.17.0 - CHANGELOG.md header + "To take advantage of v0.41.17.0" block - TODOS.md section header + v0.41.18+ forward references - CLAUDE.md inline version tags - Regenerated llms-full.txt / llms.txt No code changes. The actual workers cathedral feature set is unchanged from the two prior commits in this branch.

Master's default embedding model switched from OpenAI text-embedding-3-large (1536) to ZeroEntropy zembed-1 (1280) so a fresh PGLite brain on CI now sizes content_chunks.embedding at 1280; the test's 1536-d INSERT trips pgvector's CheckExpectedDim. Fix: probe `content_chunks.embedding` width via `readContentChunksEmbeddingDim(engine)` in `beforeAll`, store in `TEXT_DIM`, and build `fakeTextDefault(seed)` at that width. The test now passes regardless of which default ships (the model has flipped twice and may flip again). Local dev (1536 from older config) and CI fresh-install (1280 from new default) both pass. Image-side vectors stay at 1024 (matches Voyage multimodal-3 + the column's fixed width on the image side). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(test): bump PGLite hook timeout for shard-4 deep-process files facts-anti-loop.test.ts and ingest-capture.test.ts were timing out in CI shard 4 with "beforeEach/afterEach hook timed out" after the v0.41.16.0 master merge brought migration count to 99. When these files run deep in a shard process that has already created ~20 PGLite engines, the WASM cold-start + 95-migration replay legitimately exceeds bun's 5s default hook timeout (observed 5.6s and 7.3s locally when reproducing). Bun's --timeout=60000 from scripts/test-shard.sh covers TEST timeouts but NOT hook timeouts; those default to 5s and must be set per-hook via the optional 2nd arg to beforeAll/afterAll. Reproduced locally by running the first 21 shard-4 files via head -21 /tmp/shard4-list.txt | xargs bun test → 179 pass, 2 fail (both with hook-timeout error) After fix: → 198 pass, 0 fail (the 4 anti-loop + 15 ingest-capture tests recover) Full shard 4 with fix: 955 pass, 0 fail. Full shard 5 with fix: 1261 pass, 0 fail. Also added a defensive diagnostic to the two put_page tests: if facts_backstop is missing in the response payload, throw with the full payload + isError so future failures surface the actual handler error instead of a bare "expected {...} got undefined" assertion. No-op when the test passes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
