-- A shutdown that holds its listener until the exit decision, and a test suite that closes every brain it opens
-- fix(shutdown): the engine's signal handler keeps its listener registered until the exit decision is made — closing the last live instance no longer deregisters the handler mid-run, so a second signal delivery during a clean shutdown can never kill the process after the work is done (a2ea21b3)
-- fix(release): the release wall entry commits under an explicit git identity read from the developer's checkout; a host with no identity refuses by name instead of failing inside git (aac853d3)
-- test(hygiene): every brain a test file creates is closed by that file — 40 files fixed, the leaks that let a stray cadence narrate into later files are gone; brains whose init() was expected to fail are closed too (6eb5e448)

-
-- Mixed-kind fields index exactly, arrays to 256, a drained loop is not a shutdown, and finds project from the column store
-- fix(index): a metadata field holds every value kind it was written with — one posting column per (field, kind); an equality filter reads the query value's own kind, a range routes by its bounds; nothing is refused and nothing is silently dropped; an index written by the old shape opens unchanged (a128f0ed)
-- fix(metadata): metadata arrays index up to 256 elements; a longer array refuses at write time by name (MetadataArrayTooLargeError) — a vector parked in metadata now throws; move it to `vector` (e435da78)
-- fix(shutdown): beforeExit runs a non-closing flush only — a script that never calls close() exits with the writer lock on disk and no clean-shutdown marker, and the next open evicts the stale lock and folds the log, bounded; SIGTERM and SIGINT are unchanged (6baa4d7f)
-- feat(find): field projection — find({fields}) and get({fields}) resolve scalars from the column store on every leg, including vector-leg finds; absent fields stay absent (ad0f493f)
-- fix(find): orderBy is the order on every find path, not only the metadata-only one (5e720d17)
-- fix(metadata): the legacy sparse range path orders values, or refuses by name — never ranks by hash (a7eb7f52)
-- fix(close): a read-only brain writes nothing under `_system/` (f27a7776)
-- fix(contract): the flush gate's internals are private, not doors (72c8ee6a)
-- test(hygiene): the triple-intelligence correctness cases sit in the gate; the idle and connected-find pins name the brain they measure (28083981)
-- ci(release): the rail writes its own wall entry into the shared releases repo — never hand-written again (adcb883e)

-- test(batch): the batch-size-limit tests add unvectored items — they test batching, not embedding (a1423c6d)
-- fix(flush): the gate settles its waiter from the machine, never from a chain (dea3ec20)
-- test(batch): the batch-vs-individual timing assertion runs in the perf lane, not the correctness gate (ebb3a4bf)
-- test(gate): the coverage guard counts the perf lane's config as a gate (2c5e3474)
-- chore(contract): emit the 10.4.11 manifest (4142f368)
-- fix(close): a read-only brain writes no clean-shutdown evidence — the marker is the writer's word about itself (367ca721)
-- fix(generation-store): commitTransaction refuses while single-ops are pending — the order invariant is enforced, not assumed (a79db434)
-- test(shutdown): pin one owner per brain — real processes, real signals (da951990)
-- fix(shutdown): one owner per brain — the signal handler defers to close(), and flush is single-flight (ec644bde)
-- fix(vfs): a path-scoped search is a served range over the path, not a refused prefix match (65493ba2)
-- ci(test): perf and scale benchmarks leave the correctness gate (dee46b35)
-- test(open): pin the pending-embed checkpoint — stuck id, crash matrix, torn fallback (1fb51093)
-- perf(open): the pending-embed fold is bounded by a checkpoint of the SET, not an empty-only mark (15d4f65d)
-- perf(open): a sealed segment the manifest proves is below the bound is never read (bc70c43d)
-- fix(find): a page the metadata block already cut is not cut again (905c267c)

-## v10.4.4 — 2026-08-28
-
-**A correctness and observability release.** The headline is not speed: it is that a
-restart now tells you the truth about itself, a store stops lying about how much it
-holds, and the engine stops doing work nobody asked for. There is a performance
-improvement and it is modest; it is stated exactly below rather than rounded up.
-
-### The dark restart — fixed at the root
-
-A service could stop cleanly, exit 0, having awaited `close()` on every store it held,
-and its next boot would announce `Overwriting stale writer lock … appears dead` for
-every one of them. Nothing had crashed. Two deployments hit this; the same defect also
-made those boots pay a crash-recovery fold they did not owe.
-
-The cause was not the lock. `close()` released it correctly — when it got there. A
-failure part-way through close skipped both the release AND the clean-shutdown marker,
-and "the recorded pid is gone" reads identically for an orderly restart and a crash.
-
-- `close()` is now two parts and the second is unconditional: the flush-request watcher,
-  the **writer lock**, the VFS timers and the terminal `closed` flag are released whether
-  the durable steps succeeded or not. The original failure is narrated with what it costs
-  the next open, then rethrown.
-- Releasing the lock writes a **clean-close record** naming the lock generation it gave
-  up. The next open reads that record instead of guessing: recorded → nothing to recover;
-  absent → it says so, and names the recovery it is about to run. This also ends two
-  long-standing false alarms — a recycled pid locking a store out of its own reopen, and
-  `Re-acquiring writer lock … this is a bug` after a perfectly clean close.
-- The signal path stopped failing in a batch. One store's failing flush used to strand
-  every remaining store's lock and markers — at exit code 0. 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. Existing npmjs versions of
-  `@soulcraft/brainy` stay as they are and receive no new versions.
-- **The repository moved** to `soulcraftlabs/open-brainy` on The Source; the old path redirects.
-- **No engine change.** Everything in the 10.4.2 notes applies unchanged; adoption is one
-  install-line change (`@soulcraft/brainy` → `@soulcraftlabs/brainy`), which downstream
-  applications make together with their native-engine bump.
-
-## v10.4.2 — 2026-08-27 (a zero-norm vector is not a vector)
-
-**This is the last release of the MIT engine under the `@soulcraft/brainy` name.**
-The MIT package continues as **Open Brainy** — `@soulcraftlabs/brainy`: the open API,
-client library, types and protocol, an openly specified canonical format, and the TypeScript
-reference engine, scoped honestly as a single-node engine for stores up to roughly one
-million rows. 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.

-## Field Projection (`fields`)
-
-`find()` and `get()` accept a `fields` list. Without it they return the whole
-record; with it they return only the fields you name — and, where the index can
-supply them, without opening the canonical record at all.
-
-```ts
-// A list page: two user fields and one engine scalar. No document bodies.
-await brain.find({
-  where: { kind: 'post' },
-  fields: ['title', 'slug', 'system.createdAt'],
-  limit: 50
-})
-
-await brain.get(id, { fields: ['title'] })
-```
-
-### Why it exists
-
-A list view that renders a title and a date does not need the body, but without
-a projection every row hydrates its full record and throws almost all of it
-away. On a posts list that is the dominant cost of the query.
-
-### The rules
-
-| | |
-|---|---|
-| **`fields` absent** | The full record, byte-identical to before. Nothing changes. |
-| **Field names** | The one addressing law: a bare name is user metadata (`'title'`), `system.*` is an engine scalar (`'system.createdAt'`). |
-| **A field the row lacks** | Simply **absent** from the result. Never an error. |
-| **Identity** | Every row keeps its `id` (and `score` on `find`) regardless — a row you cannot identify is not a row. |
-| **Where values come from** | The **column store**, which holds raw values. Never the sparse index, which buckets timestamps for range queries. |
-| **A field the column cannot serve** | The canonical record is read for that field only. Correct, just not free. |
-
-### Missing fields are absent, not errors
-
-This is deliberate and differs from `orderBy`, which throws
-`UnresolvableFieldError` for an unknown field. A typo in `orderBy` silently
-changes the ordering, so it must be loud. A projection asks "give me these if
-you have them", and an optional field must not turn a list into a failure — so
-`fields` uses the permissive path.
-
-### Cost
-
-When every named field is column-served, a projected page performs **zero**
-canonical reads. When one is not, only that read happens and the rest still come
-from the index. Both are pinned by counting reads rather than timing them, in
-`tests/integration/find-fields-projection.test.ts`.
-
-### `related()` takes no `fields`
-
-A `Relation` carries `from` and `to` as **ids** and hydrates no entity record,
-so there is nothing for a projection to trim. Projecting the endpoints would be
-a new capability rather than a projection of an existing one.
-
-### For engine implementers
-
-Projection is served through an optional provider door,
-`getScalarsForIds(ids, fields)` on `MetadataIndexProvider`. The contract is in
-`src/plugin.ts`; the short version is **return only what you can serve exactly,
-and say what you served**. The caller diffs the answer against the request and
-reads records for the remainder, so omission costs a read while a wrong value is
-a wrong answer nobody can see. An engine without the door still works — every
-field falls back to the record.
-

-  layout above. A single-kind field is therefore byte-identical to what earlier

-- Every later kind gets its own column beside it at
-  `_column_index/{field}/k/{kind}/`, where `{kind}` is `number`, `string` or

-What that buys at query time:
-
-| | |
-|---|---|
-| **Equality** | Answered from the column matching the **query value's own kind**. `where {category: 5}` reads the number postings; `where {category: '5'}` reads the string postings. Neither borrows the other's rows — a row written with the number `5` is not a row whose category is the text `'5'`. |
-| **A kind the field never held** | Matches nothing. That is the true answer, not a coerced one. |
-| **Ranges** | Routed by the kind of the bounds: numeric bounds read the numeric postings and ignore the field's strings. An **unbounded** range is the "has any value here" probe behind `exists`, and reads every kind. |
-| **`orderBy`** | A number and a string have no order between them, so a mixed field orders by kind first (number, string, boolean) and by value within a kind. A single-kind field sorts exactly as it always did. |
-| **Numbers** | One kind, one column: an integer column is written as i64 and widens to f64 the first time a non-integer arrives, so `4.5` is stored as itself rather than rounded. |
-
-`null` and `undefined` are not kinds and are never posted; their absence is
-what the `exists` / `missing` operators read.
-
-Older readers are unaffected by the additional columns: they see the field's
-primary column exactly where it has always been, and a `k/{kind}` directory is
-simply a name they never query.

-/**
- * @module scripts/wall-entry
- * @description The releases-wall entry, made mechanical. The fleet's HQ page
- * reads one public JSON per product from the ONE releases repo on The Source
- * (soulcraftlabs/releases, files <product>.json at its root — shape
- * {product, entries:[{version, date, headline, items, url, thumb?}]}), at
- * https://source.soulcraft.com/soulcraftlabs/releases/raw/branch/main/<product>.json.
- * Those entries were hand-written after every release, then briefly written
- * into this repo's own releases/<product>.json; this script is the one door
- * that composes an entry and lands it in the shared repo, so it is never
- * hand-written and never forked across repos again.
- *
- * Two modes:
- *
- *   1. Generate + publish (default):
- *        node wall-entry.mjs --product <p> --version <v> --date <YYYY-MM-DD> \
- *          --from-changelog <CHANGELOG.md>
- *      Derives an entry from the CHANGELOG.md entry for <v> (headline = the
- *      entry's first bullet, items = every bullet, trimmed of its trailing
- *      commit hash), then:
- *        - clones (or, if a cached clone already exists, fetches and resets)
- *          the releases repo into a local cache directory,
- *        - prepends the entry to <cache>/<p>.json, newest first — replacing
- *          any existing entry for the same version so a re-run is idempotent,
- *        - validates the file's shape before and after,
- *        - commits the change as "chore(wall): <p> <v>" and pushes main.
- *      A failure at any step (clone, validation, commit, push, a
- *      non-fast-forward remote) exits non-zero naming the cure. Nothing is
- *      ever skipped — the wall either lands correctly or the release fails.
- *
- *   2. Dry run:
- *        node wall-entry.mjs --dry-run --product <p> --version <v> \
- *          --date <YYYY-MM-DD> --from-changelog <CHANGELOG.md>
- *      Derives the entry exactly as above and prints it, along with the file
- *      it would be written to, but touches no clone and no remote — usable
- *      from a fresh checkout with no cache and no network.
- *
- *   3. Validate only (--check):
- *        node wall-entry.mjs --check --file <path/to/product.json>
- *      Validates an arbitrary wall file's exact key set (top-level and
- *      per-entry), field types, and strict-descending semver ordering with
- *      no duplicates. Read-only; never writes. Exit 0 = clean, exit 1 =
- *      named violations printed to stderr.
- *
- * The remote and the local cache directory are each overridable
- * (--remote / --cache-dir, or WALL_ENTRY_RELEASES_REMOTE /
- * WALL_ENTRY_RELEASES_CACHE_DIR) so tests can point at a throwaway local
- * bare repo and a throwaway cache directory — never the real remote or the
- * real developer cache.
- *
- * No dependencies beyond the system `git` binary — CHANGELOG parsing,
- * semver comparison, and JSON shape checking are all hand-rolled below.

- * THE PRUNE LAW — which segment files a pass looking for facts ABOVE

- * recorded bounds took off the table.
- *
- * A sealed segment's `lastGeneration` is written at SEAL time and never
- * mutated upward afterwards ({@link FactLog.rotate}, unchanged since the log
- * was introduced): the tail's bytes are fsynced FIRST (`await this.sync()` —
- * "sealed segments are always fully durable"), the entry is then built from
- * the content that fsync covered, and only then does the manifest flip —
- * atomically (tmp+rename) and fsynced — which in the SAME write re-points
- * `tailSegment` at a new file, so the sealed file is never appended to again.
- * A crash anywhere in that order is safe in the pruning direction: crash
- * before the manifest write and the segment is still the TAIL (read whole);
- * crash after it and the entry describes bytes that were already durable. The
- * only later mutation of a sealed segment is `open()`'s straddle truncation,
- * which REMOVES facts and re-derives the entry from the actual bytes — so a
- * recorded bound can drift DOWN with its file, never up.
- *
- * Therefore: `lastGeneration = L` proves the file holds no fact above L, and
- * a pass above `committedGeneration >= L` can skip it whole — no read, no
- * CRC decode, no msgpack. What the manifest cannot PROVE is never pruned: an
