From 9ac9e70686eacdbf70470bf05ebf728faf034bc4 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Mon, 17 Aug 2026 16:21:25 -0700 Subject: [PATCH 1/6] feat(log): system commits carry their origin; the attested per-id reconcile door MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two consumer-driven cures sharing one stamp. (1) TX-LOG ORIGIN: engine- originated commits stamp an optional origin on their tx-log entry AND the commit fact's meta — 'system:embed-landing' (the deferred vector landing), 'system:adoption-backfill' (baseline re-commits), 'system:reconcile'. A downstream activity feed showed a double tick because the landing commit was indistinguishable from a user save, and the consumer rightly refused a time-window collapse as a quiet loss; feeds now filter on fact. User writes stay unstamped — absent origin is the user shape, every existing consumer unchanged. (2) reconcileLogDivergence(id, {attest}): the human's door for log-live-canonical-absent, the one class adoption refuses by design because a lost-tombstone deletion is indistinguishable from canonical loss. 'deleted' mints the missing tombstone (history keeps the earlier live record); 'restore' folds the log's only copy back into canonical; wrong- class calls refuse typed with nothing written. Loud, narrated, single-row, origin-stamped.

evicted writers are fenced at every commit barrier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The production dev-store split-brain (two live writers alternating a store's id-mapper between two internally-consistent truths), cured at all three of its roots. (1) STALENESS REQUIRES PID-DEATH: the old rule evicted on heartbeat age alone, so a >60s event-loop stall (debugger pause, GC, heavy sync work) handed the lock to a second opener while the first kept writing; a live process is now never auto-evicted — a wedged-but-alive holder is the operator's call via {force:true}, and the heartbeat stays for observability. (2) THE CLAIM IS ATOMIC: writeFile(wx)'s open→write→close left an empty-file window a concurrent opener could read as torn, unlink a LIVE claim, and take the lock; the claim is now tmp-write + hard-link — the lock appears with its full contents in one step. (3) THE FENCE: every flush commit and transact barrier verifies lock ownership first (one small read per window) — a forced-out or lock-deleted writer fails typed (BRAINY_WRITER_FENCED) before a single staged byte or manifest advance, instead of writing on unaware. Pinned: live-with-ancient-heartbeat refuses typed; dead-PID self-clears narrated; a forced-out writer's flush and transact both fence, advancing nothing. Requested by a downstream team as single-writer guard or loud lockout — this is both. --- src/db/generationStore.ts | 9 ++ src/db/types.ts | 10 ++ src/storage/adapters/fileSystemStorage.ts | 71 ++++++++-- src/storage/baseStorage.ts | 12 ++ tests/integration/writer-lock-fencing.test.ts | 131 ++++++++++++++++++ 5 files changed, 225 insertions(+), 8 deletions(-) create mode 100644 tests/integration/writer-lock-fencing.test.ts diff --git a/src/db/generationStore.ts b/src/db/generationStore.ts index 7439a025..065b3659 100644 --- a/src/db/generationStore.ts +++ b/src/db/generationStore.ts @@ -1394,6 +1394,10 @@ export class GenerationStore { // The transaction's entire canonical footprint is now durable, so the // counter/manifest advance below can never outrun the entity bytes. await this.storage.flushWriteBarrier?.() + // THE FENCE (transact leg): verify lock ownership before the commit + // point — an aborted-by-fence transact rolls back cleanly through the + // catch below; a fenced writer must never advance counter or manifest. + await this.storage.assertWriterFenceHeld?.() faultPoint('after-execute') // Fact log (dual-write): append + fsync this generation's AFTER-IMAGE @@ -1915,6 +1919,11 @@ export class GenerationStore { private async flushPendingSingleOpsUnlocked(): Promise { return this.withMutex(async () => { if (this.pendingGens.length === 0) return + // THE FENCE: an evicted writer (force-takeover, removed lock) must fail + // HERE, before a single staged byte or manifest advance — writing on + // after eviction is how split-brain stores are made.

Every budget is now at least 3x the worst measurement observed across three machines, each with a comment naming its calibration basis; the find-unified micro-comparison of two sub-millisecond timings becomes a ratio assertion (absolute equality of microsecond pairs can never be stable). The inference-bound trim-history correctness test gets a timeout covering its slowest observed run (174s) — its assertions are exact and untouched. These remain order-of-magnitude guards; real perf enforcement lives in the dedicated perf lanes with iron-specific budgets, per the gate-speed standard. Known non-test artifact, documented not hidden: on slow-inference machines a minutes-long awaited-embed loop can trip vitest's worker-RPC 60s tolerance ('Timeout calling onTaskUpdate') — all tests pass, vitest exits 1 on the unhandled orchestration error. The CI lanes on faster iron exit clean; if a lane ever trips it, the test moves to deterministic embeddings (its assertions are size-bookkeeping, not embedding quality). --- .../integration/find-unified-integration.test.ts | 10 ++++++++-- tests/integration/remaining-apis.test.ts | 4 +++- tests/unit/brainy/add.test.ts | 4 +++- tests/unit/brainy/batch-operations.test.ts | 15 ++++++++++++--- tests/unit/brainy/find.test.ts | 8 +++++--- .../unit/neural/NaturalLanguageProcessor.test.ts | 12 ++++++++---- tests/unit/neural/signals/EmbeddingSignal.test.ts | 10 +++++++--- 7 files changed, 46 insertions(+), 17 deletions(-) diff --git a/tests/integration/find-unified-integration.test.ts b/tests/integration/find-unified-integration.test.ts index 4370295e..94053d55 100644 --- a/tests/integration/find-unified-integration.test.ts +++ b/tests/integration/find-unified-integration.test.ts @@ -709,8 +709,14 @@ describe('Unified Find() Integration Tests', () => { expect(simpleResult.length).toBeGreaterThan(0) expect(complexResult.length).toBeGreaterThan(0) - // Simple queries should be faster - expect(simpleDuration).toBeLessThanOrEqual(complexDuration) + // These are both sub-millisecond operations on tiny fixture data, so + // comparing two microsecond-scale timings for absolute equality-class + // ordering (simple <= complex) can never be stable — timer + // resolution and scheduling noise dominate the signal.
