Now: per-store isolation, the + generation store's close (the marker) is part of shutdown, the lock goes in a `finally`, + and the handler no longer calls `process.exit()` when the host application has its own + signal handler, a race that truncated the host's own shutdown mid-flight. + +### The count ledger stops lying, and `counts.json` is written atomically + +The all-tier scalars are the denominator a coverage check subtracts against. A ledger +derived under the old rule — one entity per id DIRECTORY — counted ghost and scar +containers as rows, and was only FLAGGED suspect: it went on serving wrong numbers for +the life of the store. Two copies of one archive could disagree, and a downstream index +heal reported remaining work that did not exist. + +- Such a ledger now derives itself honestly **in the background** after the open, counting + identity records, and persists the correction stamped. Nothing waits for it, because no + read is served from a denominator. +- A derivation that raced a write refuses to stamp its number: one retry on a quiet store, + then the ledger stays SUSPECT and names `repairIndex()` as the door that recounts under + a barrier. +- `counts.json` is written temp+rename. A truncating write left a window in which a + concurrent reader saw the file EMPTY — and an unparseable ledger sends the next open + down the full-rescan path, so the cheapest file in the store was buying the most + expensive recovery. + +### An open and a repair narrate themselves — on a channel a log level cannot silence + +A store could open for three minutes and print nothing at all. The phase timings existed; +they were written to a channel that every production-looking environment clamps away. + +- Narration moved to an always-visible channel. An open now heartbeats the phase it is in, + names each phase as it ends with what it was paying for, and names the expensive STEP + inside a phase. `repairIndex()` does the same and its receipt carries a per-family + `durationMs` — a repair that ran for half an hour with no output could only be watched + through `top`. +- A brain nobody has written to now does nothing: a flush over a clean store is a no-op + and says nothing, the graph index's auto-flush asks before it acts, and the + cross-process flush-request watch is **event-driven** (`fs.watch`) instead of polling a + directory every 500 ms per store forever, with a slow safety sweep behind it and a + narrated fall back to polling where a filesystem cannot be watched. +- A provider that is REBUILDING ITSELF is no longer confused with a broken one. `init()` + does not wait for it, every other family serves, and that family's doors refuse **by + name, carrying the provider's own progress**, saying plainly that they open by + themselves and no action is needed. Health narration dedupes by content, so an unchanged + verdict is silent however a provider's generation counter moves. + +### For operators — one behaviour change + +**Four `where` operators that previously returned an empty page now raise +`INVALID_QUERY`:** `startsWith`, `endsWith`, `matches` and `length`. An equality/range +posting index cannot evaluate a substring, a pattern or an array length without reading +every row, and it now refuses by name instead of answering with an empty result that +looks like an answer. + +**Three that previously returned an empty page are now SERVED:** `hasAll`, `noneOf` and +`excludes`. All 25 accepted operator tokens now agree between this engine and its +accelerated counterpart. + +### Performance — stated exactly + +Measured on a 14,056-noun / 72,679-verb production-shaped store, both builds solo under +an exclusive lock: + +- **Warm reopen after a clean close: 85.7 s → 77.0 s (−10.2%).** The whole of that gain is + one fix — generation discovery reads directory NAMES instead of recursively walking the + entire generation log (−9.2 s, and it scales with history rather than row count). The + VFS phase is **unchanged**. +- **Cold open: −31.4 s** (518.1 s → 486.7 s), of which the count-ledger derivation moving + off the critical path accounts for storage-init dropping 5,941 ms → 25 ms. +- **A dominant ~38 s remains, diagnosed and NOT fixed.** It is not the VFS — the VFS's own + init is under 2 s of that phase. It is the log-authority adoption and/or the + pending-embed log recovery, both now instrumented so the next measurement names the + culprit outright. + +Continuing work, named so nobody has to rediscover it: that ~38 s term; making the +generation store's committed-range set lazy; the hydration path that substitutes +`Date.now()` for an unreadable stored timestamp (inventing data); and a VFS path-prefix +filter built with a `$startsWith` spelling no operator set accepts, so +`searchFiles({ path })` throws today. + +--- + +## v10.4.3 — 2026-08-27 (Open Brainy's first release) + +**`@soulcraftlabs/brainy` 10.4.3 is the same engine as `@soulcraft/brainy` 10.4.2, byte for +byte — only the name, the registry, and the pointers changed.** Install: + +```bash +npm install @soulcraftlabs/brainy +``` + +with the registry line in your `.npmrc` (anonymous read): + +``` +@soulcraftlabs:registry=https://source.soulcraft.com/api/packages/soulcraftlabs/npm/ +``` + +- **The Source is the one registry.** Open Brainy publishes to source.soulcraft.com only; the + npmjs republish step is retired from the release rail.

The `@soulcraft/brainy` name passes to the native engine, **Brainy**, at a +major version bump; that engine implements the same API over the same open format at +production scale, requires a license, and refuses loudly without one. Nothing changes +for existing installs until that major ships; the move is announced with it. + +Six fixes, one law: a vector with no magnitude carries no information, so it must +never reach a vector index — in any engine — and the canonical store must say so. + +- **The permanently-unvectored row.** `add({ ..., vector: [] })` (and the same item + shape in `addMany` / `transact`) is now the sanctioned "no vector" row: persisted + with an empty vector leg, never embedded, never indexed, counted as unvectored in + the canonical ledger. Metadata-only rows — telemetry tallies, counters, plumbing — + no longer need a placeholder vector and never enter the vector leg. `vector: []` + together with `deferEmbedding: true` is refused with a typed error (a supplied + vector has nothing to defer). Previously `vector: []` threw a dimension error. +- **The unvector door.** `update({ id, vector: [] })` (and its `transact()` twin) is + the sanctioned way to strip a vector from an existing row: canonical vector → `[]`, + removal from the vector index, the vectored ledger decremented exactly once — and + idempotent, so a resumed cleanup pass may simply re-issue. It never re-embeds, and + it clears a pending deferred-embed marker durably so the background worker cannot + re-vector the row later. Note that a rebuild never sheds vectors (it re-derives the + index from canonical rows); shedding historical vectors needs this door. +- **Zero-norm vectors are normalized at the write.** An explicit all-zero vector on + any write path is persisted as unvectored (`[]`) with one warning naming the row; + the vector-index operations keep their own refusal as a second line. The engine's + own VFS root, which used to persist a deliberate all-zero placeholder (harmless + under cosine distance, a false attractor under a downstream engine's + squared-euclidean serving — a production incident this week), is now created + unvectored, and an existing store's legacy root is migrated on open by a single + fixed-path read before the health gate runs — never a walk. +- **Enumeration keys on the identity record.** `getNouns()` / `getVerbs()` and the + cursor walks behind them enumerate by the metadata record, the same key the + canonical ledger counts by — previously the walk keyed on the vector file, so a + row holding metadata but no vector was counted yet never yielded (a permanent + "missing" phantom in coverage math), while an orphaned vector-only directory + could be yielded as a phantom id. The recovery fold also never deletes an existing + vector when it replays a metadata-only after-image (preserve-if-absent). One + documented gap remains: a verb's endpoints live only in its vector leg, so a + metadata-only verb is counted and loudly skipped, never fabricated — the fix is a + canonical-format change and lands with the open format. +- **The ledger's one-time derivation counts identity records.** Stores upgraded from + pre-ledger versions derived their ALL-visibility scalars once by counting id + directories, which included ghost and scar containers left by an old partial-delete + defect — an inflated denominator whose coverage row could never reach exact. The + derivation now counts only directories holding a metadata record, `counts.json` + carries a derivation-rule stamp, and a ledger derived under the old rule is marked + `suspect` at open (one O(1) field read, one warning) so the online `repairIndex()` + path clears it with a real recount. +- **The vector index refuses what it cannot hold.** `rebuild()` skips unvectored and + zero-norm rows (one summary line), re-pins the vector dimension from the first real + vector after a restart (previously a restart left the pin unset, so a wrong-length + insert became the new pin instead of being rejected), and `addItem` / `updateItem` + throw a typed `EmptyVectorIndexError` on a length-0 vector instead of ever storing + a vector-less node. +- **Smaller:** a failing plugin activation now rethrows with the original error as + `cause` (the originating file and line survive to the caller's log); build + generators stamp from the repository history of their inputs instead of wall clock, + so two builds of the same tree are byte-identical. + +Adoption: one restart, paired with its native-engine release. The first open of an +existing store runs the legacy-root migration (one narrated line) and, on stores that +upgraded from pre-ledger versions, marks the ledger suspect until the next sanctioned +recount — no rebuild in either case. + +## v10.4.1 — 2026-08-26 (reads refuse per family; an unchanged write never re-embeds) + +Two production defects from the same week, fixed together as a patch to 10.4.0. + +- **The read gate is per family.** A read now refuses only when the index family it + actually consults is unhealthy: a metadata filter is served while the vector leg is + rebuilding; a semantic query is refused only by the vector family; a graph + traversal only by the graph family. Previously any unhealthy family refused every + read on the brain — under a long vector rebuild, a production deployment's + metadata-only reads were refused for the duration, and the retries became a write + pump of their own. +- **Unchanged data never re-embeds.** `update()` compares the incoming `data` + structurally with the stored record; an update carrying identical data (a common + shape for periodic upserts) no longer embeds again and no longer churns the vector + leg. Previously every such update re-embedded and re-inserted, which under load + saturated the vector index with near-identical vectors. + +Adoption: one restart, paired with its native-engine release. + ## v10.4.0 — 2026-08-25 (the health report has a name) Three related cures, one root cause: an index deciding whether it could be trusted diff --git a/SECURITY.md b/SECURITY.md index 1f3c4732..91d40d49 100644 --- a/SECURITY.md +++ b/SECURITY.md @@ -30,7 +30,7 @@ commit to backporting fixes to unsupported lines. ## Scope -This policy covers the `@soulcraft/brainy` package itself — the code in +This policy covers the `@soulcraftlabs/brainy` package itself — the code in this repository.
