-
-- fix(vfs): the old-root sweep narrates only when it has something to say (d49148e1)
-- fix(tests): the health-gate pin follows the verdict, and the VFS suite uses its own store (42e2da25)
-- Merge branch 'next/open-lazy-open-and-counts' (5ebd3b40)
-- docs: the contract manifest stands alone; public docs describe this engine only (a8c724a2)
-- docs(releases): 10.4.4 consumer notes — correctness and observability, with the performance line stated exactly (61a46927)
-- docs: measurements in public history carry numbers, not provenance (02c61636)

-- fix(storage): the flush watcher cannot arm twice in its async window (16d2e1a9)
-- perf(idle): the flush-request watch is event-driven; the heartbeat is observability (fb1da1c5)
-- perf(open): answer "are there any entities?" with one directory read (417ddb51)
-- perf(generations): discover generations by directory name, not by walking the log (9dd39921)

-- fix(vectors): a zero-norm vector is not a vector, canonical side included, plus the sanctioned unvector door (0de76659)
-- fix(hnsw): skip unvectored rows on rebuild; refuse empty vectors in the index (8fc553b1)

-- build: derive generated-file stamps from git commit time, not wall clock (8a5c1245)
-- Merge remote-tracking branch 'origin/release/10.4.1' (aad9e2ee)

-- feat(repair): a heal:'repair' verdict routes to the provider's own incremental repair() (553e0d97)
-- fix(storage): an unknown nested storage config can never silently land on the shared default root (ddd5e719)
-- docs(release): the 10.4.0 entry, the index-health concept doc, and the API surfaces — written from the tree, not the plan (8cced871)
-- fix(plugins): the silent-degrade doors close — a broken accelerator install can never read as absent (b9ba50fb)
-- feat(recovery): the catchup verdict is consumed; verb rows go live; the metadata rebuild goes online (18f172e0)

-- ci(publish): the home dist-tag follows the version — a prerelease publishes under 'rc' and never moves 'latest' (a1376e4a)
-- chore(release): --source-only — a home-only prerelease mode (The Source, never the storefront) (dcbad176)
-- test(fold-checkpoint): the ARM-AT-FLIP pin arms its crash instead of racing the pending-flush timer (4176439b)
-- fix(health): one contract for a throwing probe — heal is none, serving is not withheld; repair report gains missing/rebuilt/reason (116550eb)
-- feat(storage): the canonical count ledger — ALL-visibility scalars, unclamped totals, suspect-on-unprovable-delete (7c8c8be3)
-- fix(delete): the null-metadata skip closes — index legs run id-keyed or narrate, never silently strand postings (607e9f54)
-- feat(repair): repairIndex returns the per-family receipt and narrates its summary (8d45f964)

-- test(budgets): iron-honest wall-clock budgets — 3x the worst honest-iron measurement (314e0e6c)
-- fix(locks): live writers are never auto-evicted; evicted writers are fenced at every commit barrier (292e7c04)

-- ci: the correctness plant runs integration + conformance on every push — a release never waits on a second machine (b17fdc8e)

-### [10.1.0](https://source.soulcraft.com/soulcraftlabs/open-brainy/compare/v10.0.0...v10.1.0) (2026-08-13)
-
-- docs(releases): the 10.1.0 consumer entry — bounded recovery, restore founding, the two write-path cures (7d3c8696)
-- fix(restore): a restore is an unclean event — the swap runs quiesced and the snapshot's durability stamps never survive it (9ca80667)
-- feat(recovery): the fold-checkpoint bound — crash folds (checkpoint, head], never the whole log twice (ff43de1a)
-- fix(log): pad-frame construction is total; the at-ack sync-failure compensation splits by phase — a production adoption's two write-path defects, cured at their roots (cbe34d11)
-- feat(query): the sparse-store cut — where on a never-carried field serves operator truth, never a refusal (7b67db4d)
-
-
-### [10.0.0](https://source.soulcraft.com/soulcraftlabs/open-brainy/compare/v9.0.0...v10.0.0) (2026-08-12)
-
-- fix(adoption): the baseline backfill cures hydration-law drift — existing brains reach the crash-safe default with zero operator steps (25f0dd96)
-- fix(adoption): the reserved-root mint exemption — int 0 is legitimate for exactly one id (2abe8b38)
-- fix(recovery): walks are healers — the typed/tolerant boundary redrawn where block-layer fault injection proved it belonged (0e3facf4)
-- feat(log): log authority is the fleet default — adopt-at-open, oracle-gated; plus the power-cut throw-site cures and the loud torn-record contract (214c98b4)
-- fix(durability): three block-layer power-loss findings from the first fault-injection box run — all cured, matrix 15/15 (67c606be)
-- docs: RELEASES.md frames the release as 10.0.0 — honest major (log format v2 forward-only); comment wording cleanup (d1698fa5)
-- fix(persistence): the idle flush trigger debounces under load — deferred to the floor, never dropped, never a flush-per-gap amplifier (a50726e6)
-- feat(reprojection): the one doors-open machinery — budget-capped, yielding, foreground-preempted, atomic-swap; poison records quarantine typed (d1651f98)
-- feat(embedding): deferred-embed markers become log records — the sidecar recovery path is deleted (b47787bb)
-- feat(conformance): the golden-log fold oracle — encoder bytes and fold semantics pinned by content hash (c95bea88)
-- feat(engine): the wiring wave — stamps ride every flush, provider generations, waitForIndexed, adopt-backfill, match-all serves (b53e6e89)
-- feat(index): watermark stamps on every TS projection — adopt/catchup/rescan verdicts at load, stamp-after-data (b35d87a7)
-- feat(log): v2 is the LIVE write format — envelope records with minted ints, genesis, sector seals; v1 readable forever (26c60251)
-- docs: RELEASES.md — the unreleased write-path and lifecycle entry (consumer-facing draft; version set at cut) (73eb88d4)
-- feat(temporal): as-of semantic recall joins the release contract — past vectors byte-exact, pinned (f7ca0d26)
-- fix(log): acked writes survive power loss; rejected writes never silently commit — the kill-matrix goes 11/11 with zero .fails debt (13022c51)
-- feat(plugin): every provider write surface carries the real committed generation (2d532684)
-- feat(log): fact-log format v2 codec — record envelope, type registry, genesis, sector seals; fault-injection shim (34841074)
-- feat(log): the guarded log-authority core — group-commit durable-at-ack, the per-brain switch, the verification oracle (65953097)
-- docs: Path Registry rows DP6/DP8/MT5 flip to contracted+pinned — the deferred-embedding and atomic-update train landed with cited tests (9fda6d95)
-- feat(embedding): MT5 — deferred embedding with durable markers; write acks never wait on a neural net (287384cf)
-- fix(index): the flicker window dies — atomic in-place vector update; lazy open honors every provider's not-ready report; the Path Registry twin table (ebe06cdf)
-- feat(persistence): the engine owns its flush cadence — callers never call flush() in hot paths again (3236a01b)
-- fix(aggregation): the lifecycle cluster — flush stamps, behind-stamp catches up incrementally, the native rebuild finally gets invoked, deletes are never silently skipped (1dc861d2)
-- perf(sort): ordered reads never do per-row storage round-trips — the 199-317s production scan class dies structurally (607b6b56)
-- chore: the home registry is The Source, never 'the forge' — sweep the misnomer out of the release rail, workflows, and release notes (Forge is a different product; the stored CI secret keeps its historical name) (09352c2b)
-- ci: tags stop triggering the CI matrix (redundant re-run of already-tested commits starved every release's publish run on the sequential runner) + release.sh forge poll window 20→50 min (c6c6ea6b)

-
-- docs: 9.0 namespace-migration guide — the simple story + the mechanical sweep checklist, published for humans and tooling alike (61ab9db2)
-- fix(release): storefront leg republishes CI's exact forge artifact — byte-identity by construction, verified by cross-registry shasum before the ceremony reports success (d89df2ed)
-- docs: v9.0.0 release notes — the field-addressing law migration ledger; retitle the shipped 8.11.0 canonical-enumeration entry (header went stale at its cut) (55a7512c)
-- feat(namespace): merge the field-addressing law train — no special names, system.* scalars, nested-bag storage, epoch-3 index keys (19b477ae)
-- feat(namespace): NO SPECIAL NAMES + storage fidelity — the ruled completion of the field-addressing law (24bf6cdb)
-- feat(namespace): write-door forgery refusal (user metadata keys may never start 'system.') + refusal messages name both spellings in every branch (the non-colliding case marks system.<f> honestly as NOT valid) — cross-engine message pin alignment (48a6130a)
-- feat(namespace): conformance green 19/19 — data-aware did-you-mean on unindexed bare addresses, ordering contract on the column top-K path (never drop, nulls last, ties by id), shape-complete addressed reads (entity views AND raw storage shapes, shadow-proof both scopes), per-key source matching for dotted addresses; refusal classes unified under UnresolvableFieldError (8e962dab)
-- feat(namespace): aggregation reads under the law + epoch 3 (the key-split rebuild) + THE ARMING COMMIT — the capability constant, the law module, and the typed refusals export from the package root; both engines' conformance suites light on this signal (7492b6cb)
-- feat(namespace): egress guard + validation speak the law — whereMatcher's resolver reads system.* from the record and bare names from the metadata bag only (the bare-system switch is dead); validateFindParams refuses cursor/includeRelations/writeOnly typed (accepted-and-ignored dies as a class), validates order, and parses every orderBy address (c2fb28a2)
-- fix(namespace): noun-record updates preserve legacy inline HNSW adjacency — the placeholder-adjacency write stamped out pre-codec records' stored connections (crash-window unreachability); codec-era records were never at risk (empty field is the blob marker); pin covers the legacy shape (4679c894)
-- feat(namespace): find's own filter builders speak the frozen keys — params.type/subtype/service become system.* index keys at every construction site (three pipelines + the canonical buildMetadataFilter); the where.type→noun alias is dead (bare 'type' belongs to the user now) (7a28a946)
-- feat(namespace): the index speaks the frozen keys — record-frame scalars index under literal 'system.<field>' (legacy 'noun' spelling folds into system.type; plumbing never indexed from a record frame), user fields stay bare in every shape; filter + sorted paths route every address through parseFieldAddress; storage fallbacks read the addressed side of the record (11c724bc)
-- docs(namespace): the d.ts JSDoc wave — the sealed field-addressing law on the full find + aggregation surface, present-tense, with the refusal semantics and migration note inline (comment-only; verified zero code lines changed) (fcb24ab6)
-- test(namespace): unit pins for the pure law — the ruled maps verbatim (incl. the relation mirror, unpinnable via public API), plumbing refusals both kinds, did-you-mean text (5502abcd)
-- fix(namespace): the JS sorted fallback honors the ruled ordering contract — nulls last in BOTH directions (was nulls-first on desc) + deterministic id-ascending tie-break (56deb2e8)
-- test(namespace)+docs: the cross-engine conformance suite (self-arming — skips until the resolver exports land) + the public field-addressing docs page; sidebar order deconflicted to 7 (d8d0b55f)
-- feat(namespace): the one field-addressing law as a single source of truth — parseFieldAddress + the ruled ten-scalar system maps + plumbing invisibility + refusal builders (module only; query surfaces wire in next) (8f9a9989)
-- docs: port the 8.10.3 backport-release changelog entry to main (f6b14d21)
-- docs: port the 8.10.2 backport-release changelog entry to main — release branches carry the version bump, main carries the durable record (0b059ac5)
-- fix: user metadata named 'level' is a real field everywhere — the engine-internal node layer no longer shadows it in sort/filter/aggregation, and the indexing views stop stamping a phantom 0 into its column; index epoch 2 rebuilds existing brains at first open (1a09be06)
-- fix: metadata-only update() never rewrites the noun record — the unconditional whole-vector save turned per-entity stat touches into full rewrites+fsync, amplifying read-heavy sweeps into disk saturation on a production deployment (cb717be2)
-- fix(release): double the forge-publish poll budget — the runner executes jobs sequentially and the publish run queues behind the ci matrix (64049631)

 # Contributing to Brainy
 
-Brainy is MIT-licensed and genuinely open to outside contributions. This page
-is the honest, current path — please don't rely on older instructions you
-may find elsewhere in the repo's history.
+Thank you for your interest in contributing to Brainy! This document provides guidelines and instructions for contributing to the project.
 
-## Where the project lives
+## Code of Conduct
 
-The source of truth is a self-hosted forge: **source.soulcraft.com/soulcraftlabs/open-brainy**.
-It's anonymously readable and cloneable — no account needed to browse, clone,
-or build.
+By participating in this project, you agree to abide by our Code of Conduct:
+- Be respectful and inclusive
+- Welcome newcomers and help them get started
+- Focus on constructive criticism
+- Respect differing viewpoints and experiences
 
-## How to contribute
+## How to Contribute
 
-**Found a bug, or have an idea?** Email **brainy@soulcraft.com**. No account,
-no ceremony — you'll get a receipt, and it goes to a human.
+### Reporting Issues
 
-**Want to send a patch?** Two ways, both first-class:
+Before creating an issue, please check existing issues to avoid duplicates.
 
-- **Email a patch.** Run `git format-patch` against your change and email the
-  output to **brainy@soulcraft.com**. This is a genuinely supported path, not
-  a fallback — plenty of good contributions arrive this way.
-- **Open a pull request on the forge.** Request an account at
-  **source.soulcraft.com** (registration is request-with-approval, so allow
-  a little lag), clone, push a branch, and open a PR there. Maintainers
-  review and land it.
+When creating an issue, include:
+- Clear, descriptive title
+- Detailed description of the problem
+- Steps to reproduce
+- Expected vs actual behavior
+- System information (OS, Node version, Brainy version)
+- Code examples if applicable
 
-Either way, for anything beyond a small fix, opening an issue first (email is
-fine) to talk through the approach saves everyone rework.
+### Suggesting Features
 
-## Development setup
+Feature requests are welcome! Please provide:
+- Clear use case
+- Proposed API/interface
+- Examples of how it would work
+- Any potential challenges or considerations
 
+### Pull Requests
+
+#### Before Starting
+
+1. Check existing issues and PRs
+2. Open an issue to discuss significant changes
+3. Fork the repository
+4. Create a feature branch from `main`
+
+#### Development Setup
+
+**Quick Setup (Recommended):**
 ```bash
-git clone https://source.soulcraft.com/soulcraftlabs/open-brainy.git
+# Clone your fork
+git clone https://github.com/your-username/brainy.git
 cd brainy
+
+# Run setup script (installs all dependencies including Rust)
+./scripts/setup-dev.sh
+```
+
+**Manual Setup:**
+```bash
+# Clone your fork
+git clone https://github.com/your-username/brainy.git
+cd brainy
+
+# Install system dependencies (Ubuntu/Debian)
+sudo apt-get install -y build-essential pkg-config libssl-dev
+
+# Install Rust (for WASM embedding engine)
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+source ~/.cargo/env
+rustup target add wasm32-unknown-unknown
+cargo install wasm-pack
+
+# Install Node.js dependencies
 npm install
+
+# Build Candle WASM embedding engine
+npm run build:candle
+
+# Build TypeScript
 npm run build
+
+# Run tests
 npm test
 ```
 
-Tests run on [Vitest](https://vitest.dev/). `npm test` runs the unit suite;
-see `package.json` for `test:integration`, `test:coverage`, and friends.
+#### Making Changes
 
-## Standards
+1. **Follow the code style**
+   - TypeScript for all source code
+   - Clear variable and function names
+   - Comments for complex logic
+   - JSDoc for public APIs
 
-- **Strict TypeScript.** No `any` escape hatches to dodge the type checker.
-- **Tests exercise real behavior.** No mocking away the thing you're supposed
-  to be testing.
-- **No stubs, no TODO-code.** If something can't be finished, say so and
-  leave it out — don't merge a placeholder.
-- **JSDoc on every exported function, class, and type.**
-- **[Conventional Commits](https://www.conventionalcommits.org/).** `feat:`,
-  `fix:`, `docs:`, `perf:`, `refactor:`, `test:`, `chore:`. Never
-  `BREAKING CHANGE` in a commit message — major version bumps are a separate,
-  deliberate decision.
-- **Performance claims are measured or labeled projected.** If a PR or its
-  description states a number, cite the benchmark that produced it (see
-  [docs/performance-envelopes.md](docs/performance-envelopes.md) for the
-  pattern). Don't state an estimate as if it were measured.
-- **Measurements carry numbers, not provenance.** Public commit messages and
-  docs give the SHAPE a number was taken at and never where it was taken: no
-  hostnames, no store or deployment identities, no operational anecdotes about
-  someone's running system. "A 14,056-noun / 72,679-verb production-shaped
-  store, measured solo under an exclusive lock" tells a reader everything the
-  number depends on; the machine it ran on and whose data it was tell them
-  nothing except where somebody's infrastructure lives.
-- **Documents that answer or reference a confidential specification never enter
-  this repository, even summarized.** The public docs describe THIS engine and
-  the published contract, and nothing else — a summary of a private document is
-  still that document's contents.
+2. **Write tests**
+   - Add tests for new features
+   - Update tests for changes
+   - Ensure all tests pass
 
-## License
+3. **Update documentation**
+   - Update README if needed
+   - Add/update API documentation
+   - Include examples
 
-Brainy is [MIT licensed](LICENSE). Contributions are accepted under the same
-license — there's no CLA to sign.
+#### Commit Guidelines
 
-Thank you for considering a contribution.
+Follow conventional commits format:
+
+```
+type(scope): description
+
+[optional body]
+
+[optional footer]
+```
+
+Types:
+- `feat`: New feature
+- `fix`: Bug fix
+- `docs`: Documentation changes
+- `style`: Code style changes
+- `refactor`: Code refactoring
+- `perf`: Performance improvements
+- `test`: Test changes
+- `chore`: Build/tooling changes
+
+Examples:
+```bash
+feat(triple): add graph traversal depth limit
+fix(storage): handle concurrent write conflicts
+docs(api): update search method documentation

+
+#### Submitting PR
+
+1. Push to your fork
+2. Create PR against `main` branch
+3. Fill out PR template
+4. Ensure CI checks pass
+5. Wait for review
+
+### Testing
+
+#### Running Tests
+
+```bash
+# Run all tests
+npm test
+
+# Run specific test file
+npm test tests/core.test.ts
+
+# Run with coverage
+npm run test:coverage
+
+# Watch mode
+npm run test:watch
+```
+
+#### Writing Tests
+
+```typescript
+import { describe, it, expect } from 'vitest'
+import { Brainy } from '../src'
+
+describe('Feature Name', () => {
+  it('should do something specific', async () => {
+    const brain = new Brainy()
+    await brain.init()
+    
+    // Test implementation
+    const result = await brain.search("test")
+    
+    expect(result).toBeDefined()
+    expect(result.length).toBeGreaterThan(0)
+  })
+})
+```
+
+## Architecture Guidelines
+
+### Adding New Features
+
+1. **Check existing functionality**
+   - Review `ARCHITECTURE.md`
+   - Check if similar features exist
+   - Consider if it should be an augmentation
+
+2. **Design considerations**
+   - Maintain backward compatibility
+   - Consider performance impact
+   - Think about all storage adapters
+   - Plan for extensibility
+
+3. **Implementation checklist**
+   - [ ] Core functionality
+   - [ ] Tests (unit and integration)
+   - [ ] Documentation
+   - [ ] TypeScript types
+   - [ ] Examples
+   - [ ] Performance benchmarks (if applicable)
+
+### Creating Augmentations
+
+Augmentations extend Brainy's functionality:
+
+```typescript
+import { BrainyAugmentation } from '../types'
+
+export class MyAugmentation extends BrainyAugmentation {
+  name = 'MyAugmentation'
+  
+  async onInit(brain: Brainy): Promise<void> {
+    // Initialize augmentation
+  }
+  
+  async onAdd(item: any, brain: Brainy): Promise<any> {
+    // Process before adding
+    return item
+  }
+

+
+## Documentation
+
+### API Documentation
+
+Use JSDoc for all public APIs:
+
+```typescript
+/**
+ * Searches for similar items using vector similarity
+ * @param query - Search query (text or vector)
+ * @param options - Search options
+ * @returns Array of search results with scores
+ * @example
+ * ```typescript

+ * ```
+ */
+async search(query: string | Vector, options?: SearchOptions): Promise<SearchResult[]> {
+  // Implementation
+}
+```
+
+### Examples
+
+Add examples for new features:
+
+```typescript
+// examples/feature-name.ts
+import { Brainy } from 'brainy'
+
+async function exampleUsage() {
+  const brain = new Brainy()

-**Open Brainy** is the MIT engine — the open API, client library, types, and protocol; an openly specified canonical on-disk format; and this TypeScript reference engine, scoped as a single-node engine for stores up to roughly one million rows. `@soulcraft/brainy` 10.4.2 was the last release under the old package name — the name passes to the native engine, **Brainy**, at 11.0.0: the same API over the same open format at production scale, and it requires a license.

 Built because we were tired of stitching a vector store to a graph database to a document store — and spending weeks on plumbing before writing a line of business logic. Brainy indexes every fact **three ways at once** and lets one call query them together:

-
-## Reporting a vulnerability
-
-Email **security@soulcraft.com**. That's the one door for security reports
-across the company, and it works the same way for Brainy: every report is
-read by a human, you'll get a private receipt, and we'll work with you on
-coordinated disclosure — please don't open a public issue for anything
-that isn't already public.
-
-Include what you'd want if you were on the other end: affected version,
-how to reproduce, and what you think the impact is. If you have a patch or
-a suggested fix, send it along — it's welcome but not required.

-
-## Response time
-
-We respond as fast as truth allows. That means: no fixed SLA, no promise of
-a reply within a specific number of hours — but a real report from a real
-person gets read promptly and taken seriously. If you haven't heard anything
-in a reasonable stretch, a follow-up email is completely fine.

-## Supported versions
-
-The latest `8.x` minor release line receives security fixes. If you're

-commit to backporting fixes to unsupported lines.

+## Lazy Loading Performance
 
-As of 10.4, `brain.init()` runs every needed index rebuild to completion before
-it returns — always, regardless of dataset size. There is no lazy,
-first-query rebuild path: a brain either finishes opening healthy, or `init()`
-fails loudly. `disableAutoRebuild` no longer defers index construction to a
-first query; it has no effect on *when* a rebuild runs. Manual control over
-rebuilds is `repairIndex({ rebuild: [...] })`. See
-[Index Health](concepts/index-health.md) for the full read-gate contract
-(providers self-report readiness via `healthReport()`; a read against a
-not-serving provider throws a typed `*NotReadyError` rather than rebuilding
-mid-query).
+Brainy supports two initialization modes for optimal performance across different use cases:
 
-<!-- The pre-10.4 "Mode 2: Lazy Loading on First Query" section previously
-     documented here (disableAutoRebuild deferring index construction to the
-     first find() call) described a real, now-retired code path. Removed
-     rather than left to mislead; the concept doc above is the current
-     contract. -->
+### Mode 1: Auto-Rebuild (Default)
+
+```javascript
+const brain = new Brainy()
+await brain.init()  // Rebuilds indexes during init (~500ms-3s for 10K entities)
+```
+
+**Performance:**
+- Init time: 500ms-3s (depends on dataset size)
+- First query: Instant (indexes already loaded)
+- Use case: Traditional applications, long-running servers
+
+### Mode 2: Lazy Loading
+
+```javascript
+const brain = new Brainy({ disableAutoRebuild: true })
+await brain.init()  // Returns instantly (0-10ms)
+
+const results = await brain.find({ limit: 10 })  // First query triggers rebuild (~50-200ms)
+const more = await brain.find({ limit: 100 })    // Subsequent queries instant (0ms check)
+```
+
+**Performance:**
+- Init time: 0-10ms (instant)
+- First query: 50-200ms (includes index rebuild for 1K-10K entities)
+- Subsequent queries: 0ms check (instant)
+- Concurrent queries: Wait for same rebuild (mutex prevents duplicates)
+
+**Concurrency Safety:**
+```javascript
+// 100 concurrent queries immediately after init
+await brain.init()
+
+const promises = Array.from({ length: 100 }, () =>
+  brain.find({ limit: 10 })
+)
+
+const results = await Promise.all(promises)
+// ✅ Only 1 rebuild triggered (mutex)
+// ✅ All 100 queries return correct results
+// ✅ Total time: ~60ms (not 6000ms!)
+```
+
+**Use Cases for Lazy Loading:**
+- **Serverless/Edge**: Minimize cold start time (0-10ms init)
+- **Development**: Faster restarts during development
+- **Large datasets**: Defer index loading until needed
+- **Read-heavy workloads**: Writes don't wait for index rebuild

-### Index readiness: typed errors, `healthReport()`, `disableAutoRebuild`
-
-Every derived-index provider (vector, graph, metadata) may expose a named,
-synchronous, O(1) `healthReport()` composed from its own exact ledgers — the
-signal Brainy's read gate trusts over sampling or size heuristics. `init()`
-brings every provider to serving before it returns; there is no first-query
-lazy-rebuild path. A read that reaches a provider whose health report says it
-isn't serving throws instead of rebuilding mid-query:
-
-| Error | Thrown by | Meaning |
-|---|---|---|
-| `GraphIndexNotReadyError` | `find({ connected })`, `neighbors()`, `related()` | Graph adjacency isn't serving |
-| `MetadataIndexNotReadyError` | `find({ where })` | Metadata/field index isn't serving |
-| `VectorIndexNotReadyError` | `find({ query })`, `similar()` | Vector index isn't serving |
-
-All three are exported from `@soulcraftlabs/brainy`. Catch them to distinguish
-"index not ready" from a genuine empty result:
-
-```typescript
-import { MetadataIndexNotReadyError } from '@soulcraftlabs/brainy'
-
-try {
-  const rows = await brain.find({ where: { status: 'active' } })
-} catch (err) {
-  if (err instanceof MetadataIndexNotReadyError) {
-    // reconcile: await brain.repairIndex(), then retry
-  } else {
-    throw err
-  }
-}
-```
-
-**`disableAutoRebuild`** no longer defers index construction to the first
-query. A needed rebuild always runs at `open()`, regardless of this flag or
-dataset size; the flag has no effect on *when* a rebuild runs. Full manual
-control lives in `repairIndex({ rebuild: [...] })`, above.
-
-### `validateIndexConsistency()` → `Promise<...>`
-
-The deep, async diagnostic counterpart to `healthReport()` — safe to run on a
-live brain, but does more work (a provider's `validateInvariants()` may run a
-full scan, not just read a ledger). Aggregates the JS metadata index's own
-consistency check with every derived-index provider's invariant report.
-
-```typescript
-const validation = await brain.validateIndexConsistency()
-if (!validation.healthy) {
-  console.log(validation.recommendation) // what to run, e.g. repairIndex()

----
-
-# Field addressing: your fields and system fields
-
-Every query surface in Brainy — `find()`'s `where`, `orderBy`, aggregation
-`groupBy`, and aggregation `source.where` — resolves field names by one rule,
-with no exceptions:
-
-> **A bare field name always means your metadata. `system.<field>` reaches an
-> engine scalar, and only when you spell it explicitly.**
-
-```typescript
-await brain.find({ orderBy: 'level' })          // reads entity.metadata.level — YOUR field
-await brain.find({ orderBy: 'system.createdAt' }) // reads the engine's createdAt scalar
-await brain.find({ orderBy: 'metadata.level' })   // identical to bare 'level' — explicit scope
-```
-
-There is no priority list, no "try the system field, fall back to metadata"
-behavior, and no name that resolves differently depending on what else
-happens to exist on your entities. A field called `level`, `score`,
-`createdAt`, or `type` in your own `metadata` is read as *your* field, every
-time, by its bare name.
-
-## Why this rule exists
-
-An internal report from a production deployment found that a user metadata
-field literally named `level` was being silently shadowed by the engine's
-own internal index layer field of the same name — every sort by `level`
-returned insertion order, with no error raised. This rule makes that class of
-bug structurally impossible: bare names belong to you, unconditionally, and
-anything that isn't yours has to be spelled out.
-
-## The system scalars
-
-`system.<field>` addresses exactly ten scalars on an entity — no more, no
-fewer:
-
-| System field | What it is |
-|---|---|
-| `system.id` | The entity's id |
-| `system.type` | The entity's `NounType` |
-| `system.subtype` | The per-app sub-classification passed to `add()` |
-| `system.createdAt` | When the entity was created |
-| `system.updatedAt` | When the entity was last written |
-| `system.confidence` | The `confidence` param (0–1) |
-| `system.weight` | The `weight` param |
-| `system.visibility` | `'public'` / `'internal'` (see the visibility tiers in [Consistency Model](./consistency-model.md)) |
-| `system.service` | The multi-tenancy `service` tag |
-| `system.createdBy` | Who/what created the entity |
-
-Relationships mirror the same eight shared scalars (`subtype`, `createdAt`,
-`updatedAt`, `confidence`, `weight`, `visibility`, `service`, `createdBy`)
-plus three of their own:
-
-| System field (relationship) | What it is |
-|---|---|
-| `system.verb` | The relationship's `VerbType` |
-| `system.sourceId` | The id of the entity the relationship starts from |
-| `system.targetId` | The id of the entity the relationship points to |
-
-Anything not on these two lists is not a system scalar — `system.<name>` for
-any other name refuses (see "Refusal semantics" below), even if that name
-sounds like it should be engine-owned.
-
-## Invisible plumbing — never addressable, in either spelling
-
-Five names are pure engine internals. They are not reachable as a bare name,
-and not reachable as `system.<name>` either — they simply have no place on
-the query surface:
-
-- **`vector`** — the stored embedding. It participates in similarity search
-  (`query`, `near`, vector `find()`), never in `where`/`orderBy`/`groupBy`.
-- **`connections`** — graph adjacency. Reached through `connected` and
-  `brain.related()`, not through field addressing.
-- **`level`** — the internal index layer number used by the nearest-neighbor
-  graph. It is pure index plumbing with no query-surface meaning at all —
-  which is exactly why a user field of the same name must never be shadowed
-  by it. `level` as a bare name is always yours; there is no engine-owned
-  spelling of it to compete with.
-- **`data`** — your entity's content payload, not a scalar. It can be a
-  string, a number, or an arbitrary object, so sorting or filtering it as a
-  single comparable value would lie about its actual shape. Content is
-  reached through the content/text-search APIs (`query`, `searchMode:
-  'text'`), not through `where`/`orderBy`.
-- **`_rev`** — the per-entity revision counter used for optimistic
-  concurrency (`ifRev`). It is a CAS token, not a queryable dimension.
-
-`system.level`, `system.vector`, and `system.data` all refuse for the same
-reason: they are not in the ten-scalar system map, full stop.
-
-## `metadata.<field>` — the explicit spelling of "mine"
-
-Prefix any field with `metadata.` to say the same thing a bare name already
-says, spelled out. The two are interchangeable everywhere a field name is
-accepted, including `orderBy`:
-
-```typescript
-await brain.find({ where: { 'customer.tier': 'gold' } })
-await brain.find({ where: { 'metadata.customer.tier': 'gold' } })   // identical
-await brain.find({ orderBy: 'metadata.score', order: 'desc' })      // identical to orderBy: 'score'
-```
-
-Reach for the explicit spelling when it reads more clearly next to a
-`system.` field in the same query — for example, sorting by your own `score`
-while filtering on `system.confidence`.
-
-## No special names — the write side
-
-The same law governs writes:
-
-> **Data is either in main space, where developers can use anything, or it
-> is in `system.*`.**
-
-There are **no reserved metadata names**. A field called `confidence`,
-`type`, `id`, `data`, `content`, or anything else inside your `metadata` bag
-is an ordinary user field: it is stored verbatim, indexed, filterable,
-sortable, aggregatable, and it survives restarts, index rebuilds, and
-time-travel (`asOf`) reads exactly as written — even when an engine scalar
-shares its spelling. The engine's values are written only through their
-dedicated params (`confidence`, `weight`, `subtype`, `visibility`, …) and
-read at `system.<field>`; your bag can never touch them and they can never
-shadow your bag.
-
-```typescript
-const id = await brain.add({
-  data: 'Ada Lovelace',
-  type: NounType.Person,
-  confidence: 0.9,                       // the ENGINE scalar
-  metadata: { confidence: 'self-rated' } // YOUR field, same spelling — both live
-})
-
-await brain.find({ where: { confidence: 'self-rated' } })      // finds it (yours)
-await brain.find({ where: { 'system.confidence': 0.9 } })      // finds it (engine's)
-```
-
-The one spelling a write refuses is a metadata key that literally starts
-with `system.` — the explicit address namespace cannot be forged as a user
-field name. That refusal is typed and names the fix.
-
-Value **shape** rules still apply uniformly to every name (they are not name
-carve-outs): arrays longer than 10 elements are not turned into posting-list
-scalars, and very long values are indexed by hash.
-
-## Refusal semantics
-
-A name that resolves to neither your metadata nor a system scalar is a typed
-refusal, not a silent empty result and not a guess. Refusals name **both**
-candidates, so the fix is always in the error text:
-
-```typescript
-await brain.find({ orderBy: 'createdAt' })
-// UnresolvableFieldError: no metadata field 'createdAt' — did you mean
-// system.createdAt or metadata.createdAt?
-```
-
-`UnresolvableFieldError` is exported from the package root:
-
-```typescript
-import { UnresolvableFieldError } from '@soulcraftlabs/brainy'
-
-try {
-  await brain.find({ orderBy: 'createdAt' })
-} catch (err) {
-  if (err instanceof UnresolvableFieldError) {
-    // err.message names both candidates — usually enough to fix the call site.
-  }
-}
-```
-
-A handful of `find()` options are not implemented yet: `cursor`,
-`includeRelations`, and `writeOnly`. Rather than accepting them and quietly
-ignoring the option, `find()` refuses with `UnsupportedFindOptionError` —
-also exported from the package root — so a call site can never believe an
-unimplemented option took effect when it didn't.
-
-## The ordering contract
-
-`orderBy` behaves identically regardless of which engine (the pure-TypeScript
-path or a native accelerator) is serving the query:
-
-- An entity missing the `orderBy` field, or holding `null` on it, sorts
-  **LAST — in both `asc` and `desc`**. It is never treated as "smaller than
-  everything" in one direction and "larger than everything" in the other; it
-  is simply last, either way.
-- Rows are **never dropped** from an ordered read because they lack the
-  field — a missing value changes position, never presence.
-- Ties on the `orderBy` field break by **id ascending**, regardless of the
-  primary sort direction.
-
-```typescript
-// employees: [{ score: 9 }, { score: 5 }, { /* no score field */ }]
-await brain.find({ orderBy: 'score', order: 'desc' }) // [9, 5, missing] — missing is last
-await brain.find({ orderBy: 'score', order: 'asc' })  // [5, 9, missing] — missing is STILL last
-```
-
-## Migrating existing call sites
-
-If you have call sites written before this rule shipped that rely on a bare
-system name — `orderBy: 'createdAt'`, `where: { confidence: { greaterThan:
-0.8 } }`, and similar — they now refuse instead of silently resolving to the
-engine field. The fix is always in the error: swap the bare name for
-`system.<field>` (or `metadata.<field>` if you actually meant your own field
-of that name, and it happens to share a name with a system scalar):
-
-```typescript
-// Before: bare 'createdAt' silently meant the engine's timestamp.
-await brain.find({ orderBy: 'createdAt' })
-
-// After: say which one you meant.
-await brain.find({ orderBy: 'system.createdAt' })   // the engine timestamp
-await brain.find({ orderBy: 'metadata.createdAt' }) // your own field named createdAt, if you have one
-```
-
-There is no silent migration path by design — every ambiguous call site
-surfaces as a refusal naming its own fix, once, the first time it runs
-against the new rule.

-# The Generation Fact Log
-
-Since 8.4.0, every committed generation also appends a **fact** — a compact record of what each
-touched entity or relationship *became* — to an append-only, checksummed log under
-`_generations/facts/`. Where the generational history answers *"what did things look like
-before?"* (before-images, powering `asOf()` and rollback), the fact log answers *"what happened,
-in order?"* — one sequential, self-verifying stream of the store's present being written.
-
-Nothing about querying changes. The fact log exists for three consumers:
-
-1. **Index heals and rebuilds** — one sequential read in commit order replaces a per-entity
-   directory walk over millions of files.
-2. **Incremental catch-up** — a derived index that knows which generation it reflects reads *just
-   the gap*, instead of rebuilding from scratch.
-3. **Replay and audit tooling** — anything that wants the store's committed timeline as a stream.
-
-## What a fact is
-
-One fact per committed generation:
-
-- **`generation`** and **`timestamp`** — which commit, when.
-- **`ops`** — every write in that commit: `{ kind: 'noun' | 'verb', id, record }` where `record`
-  holds the entity's full after-image (both stored legs), or **`null` for a tombstone** — a
-  removal carries no body, by design.
-- **`meta`** — the transaction metadata `transact()` was submitted with, when present.
-- **`blobHashes`** — content-blob references, for exact reclamation accounting.
-
-Facts accumulate **from the first write after upgrading** — pre-existing history is not
-retroactively converted, and consumers fall back to the enumeration walk when no log exists.
-
-## Crash safety, in one paragraph
-
-Facts are appended and fsynced **inside the same durability window as the commit itself**, before
-the commit point — so after a crash, the log can only ever be *ahead* of committed truth, never
-behind it with a hole. On open, the store reconciles the log back to the committed watermark:
-torn tails are detected by per-record checksums and cut; whole records beyond the watermark are
-truncated. The invariant every reader can rely on: **an absent generation was never committed; a
-present fact was.** `transact()` facts are durable the moment `transact()` returns; single-op
-facts share the same group-commit flush as the rest of their generation, so a hard kill loses the
-fact and the generation *together* — never a torn state.
-
-## Reading the log
-
-```typescript
-const scan = brain.scanFacts({ fromGeneration: 1 })
-if (scan) {
-  // Telemetry up front — progress bars get a denominator from second zero.
-  console.log(scan.headGeneration, scan.segmentCount, scan.approxFactCount)
-
-  for await (const batch of scan.batches()) {
-    // Each batch: { facts, firstGeneration, lastGeneration, factCount, byteSize, segmentId }
-    for (const fact of batch.facts) {
-      for (const op of fact.ops) {
-        if (op.record === null) {
-          // a tombstone: op.id was removed in this generation
-        }
-      }
-    }
-  }
-
-  console.log(scan.summary()) // { factsYielded, segmentsRead } — the cross-check
-}
-```
-
-- `scanFacts()` returns `null` when the store hosts no fact log (older store, or a storage adapter
-  without binary append support) — fall back to enumerating entities.
-- Scans run against a **snapshot**: facts appended after the scan opens never bleed in, each fact
-  is yielded exactly once, and a detected gap aborts loudly — never a silent skip.
-- `brain.factSegmentPaths()` returns the immutable, *sealed* segment files for zero-copy consumers
-  (the append-mutable tail is excluded — read it through `scanFacts()`).
-
-## Family stamps: how a projection proves it's current
-
-Anything derived from the store — an index, the entity file tree itself — carries a **family
-stamp**: a small JSON record of *which committed generation the projection reflects*
-(`sourceGeneration`) plus the invariants that verify it whole (exact per-file byte sizes for
-bounded families; rollup invariants like entity counts for unbounded ones). At open, coherence is
-a **comparison**, not a walk:
-
-- stamp equals the committed watermark and invariants hold → serve;
-- stamp is behind → the projection reads just the gap from the fact log;
-- invariants fail → loud, named divergence — `brain.repairIndex()` rebuilds from canonical and
-  re-stamps.
-
-The verifier is exported (`verifyFamilyStamp`) so every projection — TypeScript or native — runs
-literally the same check.
-
-## For plugin authors: the storage capability
-
-Index providers receive the storage adapter, not the brain — so the host wires the log onto it.
-Feature-detect and prefer the stream; fall back to enumeration:
-
-```typescript
-const scan = storage.scanFacts?.({ fromGeneration: stamp.sourceGeneration + 1 })
-if (scan) {
-  // sequential catch-up from the log
-} else {
-  // enumeration walk (older store or adapter)
-}
-const committed = storage.committedGeneration?.() // the watermark stamps compare against
-```
-
-Providers must never construct their own reader over the log's files — the open path belongs to
-the single writer (it reconciles the log at open); the capability is the sanctioned seam.

-# Index Health
-
-Brainy keeps one **canonical** copy of every entity and relationship, and three
-**derived** indexes built from it — vector, metadata, and graph — so `find()` can
-answer semantically, by filter, and by traversal without re-deriving the answer from
-scratch on every query. A derived index is a cache with a serving structure: it can
-be present but stale, present but only partially loaded, or fully out of sync with
-canonical after a crash. This page is about how Brainy decides whether to trust one,
-what it does when it can't, and how you reconcile the two.
-
-## Exact accounting instead of sampling
-
-Older health checks worked by inference: does `size()` return something greater
-than zero, does a spot-check on one known item come back correct. Both are proxies.
-A cold index can report a nonzero count while its actual serving structure never
-loaded, and a spot-check only proves the one item it happened to ask about.
-
-Every derived-index provider may now expose a named, synchronous, O(1)
-`healthReport()` — composed from the provider's own **exact ledgers** (real counters
-it already maintains on the write path), never a sample or a walk. This is the one
-signal Brainy's read gate consults. A provider that doesn't yet expose one falls
-back to an honest `isReady()` boolean, and finally to a size heuristic for engines
-with neither — but wherever a `healthReport()` exists, it wins.
-
-Underneath, storage itself keeps an analogous **canonical count ledger**: a
-`counted` scalar (the user-facing total — what `getNounCount()` / `getVerbCount()`
-return) and an `all` scalar (every tier, including internal records a derived
-index's own coverage math needs to compare against). This is the real denominator
-a provider's `healthReport()` measures itself by, rather than a total that can only
-ever ratchet upward. See [What `suspect` counts mean](#what-suspect-counts-mean)
-below for the one case that ledger can't stay exact through on its own.
-
-## The named report
-
-A `HealthReport` carries, per provider (`'vector'` / `'graph'` / `'metadata'`):
-
-- **`healthy`** — `true` iff every *verified* invariant holds. An invariant whose
-  family has no ledger yet is `unledgered`, never counted either way — unknown,
-  not passing.
-- **`serving`** — can this provider answer a query right now. A failing invariant
-  graded `heal: 'repair'` or `heal: 'none'` still leaves `serving: true` — this is
-  **degraded-but-serving**: something is off (say, a stale rollup on an
-  `employee` record's relationship count) but reads keep working. Only a failure
-  graded `heal: 'rebuild'` flips `serving` to `false` — **not-ready** — because the
-  provider itself is telling you its serving structure cannot answer correctly.
-- **`invariants`** — each checked condition, with its provenance
-  (`source: 'ledger'` — an exact count; `'deep'` — a full scan, diagnostic-only;
-  `'unledgered'` — not yet tracked) and, for a failing one, an exact `missing`
-  count plus a capped sample of the affected ids — a verdict, never a dump.
-- **`generation`** — bumps on every ledger mutation and rebuild, so a caller can
-  cache a verdict per generation instead of re-deriving it.
-
-The distinction that matters day to day: `healthy: false` can be entirely benign —
-a maintenance window, a divergence `repairIndex()` will clean up on its own
-schedule. `serving: false` is not benign. It means this provider is refusing to
-answer, on its own word, right now.
-
-**How a failure gets its grade — the serving law.** A provider grades `heal` by
-one question only: *could an answer be wrong?* — never *how expensive is the
-fix?* A missing-postings shortfall, however large, is `heal: 'repair'` (re-post
-exactly what the ledger names, reads serving throughout); it can never withhold
-serving just because healing it takes work. `serving` is withheld only by a
-small, named set of rebuild-graded conditions — the index not initialized, its
-durable state absent, a manifest naming files that are not resident, a replay
-that did not complete cleanly — the states in which an answer could genuinely be
-wrong. And a read is only ever refused by the family it actually consults: a
-metadata filter is answered by the metadata index alone, vector search by the
-vector index, traversal by the graph index — one family's refusal never blocks
-another family's reads.
-
-## Reads refuse — they never rebuild
-
-A query that reaches a not-serving provider does not trigger a rebuild from inside
-the read. Brainy retired that path deliberately: a rebuild kicked off by an ordinary
-`find({ where: { status: 'active' } })` call is a dark, unpredictable cost hiding
-behind a request that looks like a cheap read. Instead, the read throws a typed,
-catchable error naming the reason:
-
-| Error | Thrown when | Meaning |
-|---|---|---|
-| `GraphIndexNotReadyError` | `find({ connected })`, `neighbors()`, `related()` | The graph adjacency index isn't serving — traversal would otherwise return `[]` indistinguishable from "no relationships" |
-| `MetadataIndexNotReadyError` | `find({ where })` | The metadata/field index isn't serving — a filtered read would otherwise return `[]` indistinguishable from "no matches" |
-| `VectorIndexNotReadyError` | `find({ query })`, `similar()` | The vector index isn't serving — a semantic search would otherwise return `[]` indistinguishable from "nothing similar" |
-
-All three are exported from `@soulcraftlabs/brainy`. Catch them where your application
-needs to distinguish "this index isn't ready yet" from "there's genuinely nothing
-here" — a health dashboard, a retry policy, an operator alert. The fix is always
-the same: reconcile the index, either by reopening the brain (which brings every
-provider to serving before `init()` returns — see the next section) or by calling
-`repairIndex()` explicitly.
-
-```typescript
-try {
-  const active = await brain.find({ where: { status: 'active' } })
-} catch (err) {
-  if (err instanceof MetadataIndexNotReadyError) {
-    // not a "no results" — the index itself refused; alert or retry after repair
-  } else {
-    throw err
-  }
-}
-```
-
-### Rebuilds happen at open, not on first query
-
-`brain.init()` runs every needed rebuild to completion **before it returns**,
-unconditionally, regardless of dataset size. There is no lazy, first-query
-rebuild path anymore — a brain either finishes opening healthy, or it fails
-open loudly. `disableAutoRebuild: true` no longer defers index construction to
-the first query: it has no effect on *when* a needed rebuild runs. Full manual
-control over rebuilds is `repairIndex({ rebuild: [...] })` (below), not this flag.
-
-## `repairIndex()` — checking and healing
-
-Bare `repairIndex()` is **report-driven**: it only heals what its own checks say
-actually needs it, and it always returns a full per-family receipt.
-
-```typescript
-const report = await brain.repairIndex()
-report.healedTotal   // total items healed across every family
-report.durationMs
-report.families       // one row per family checked
-```
-
-Each `RepairFamilyReport` row names what happened:
-
-- **`checked`** — was this family actually examined (`false` means skipped —
-  see `skipped` for why).
-- **`healed`** — items re-posted or corrected in place.
-- **`missing`** — when the check can name what diverged: an exact `count` plus a
-  capped `sample` of ids.
-- **`rebuilt`** — a full generational rebuild ran (as opposed to an incremental
-  heal).
-- **`detail`** / **`reason`** / **`skipped`** — the receipt's narration; a row is
-  always either checked or explains why it wasn't. Nothing is silent.
-
-On every call, bare `repairIndex()`:
-
-1. Prunes orphaned canonical containers left by a partial delete.
-2. Recomputes the count rollups from one canonical walk (unconditional — this is
-   also what clears a `suspect` ledger; see below).
-3. Reconciles VFS containment edges, if the VFS is initialized.
-4. Runs the metadata index's own corruption detection pass.
-5. Consults each of the three derived-index providers' own health check and
-   rebuilds only a family whose failing invariant actually asks for it
-   (`heal: 'rebuild'`) — never a provider that reports `healthy` or a lesser
-   grade.
-
-### The explicit rebuild door
-
-`options.rebuild` skips the health check and rebuilds one or more families
-**unconditionally** — the operator override for when you have independent reason
-to distrust a family regardless of what it self-reports (a suspicious deploy, a
-storage-layer incident, a support ticket that doesn't match what the health report
-says):
-
-```typescript
-// Force the graph adjacency to rebuild from canonical, no invariant consulted
-await brain.repairIndex({ rebuild: ['graph'] })
-
-// Force all three derived indexes
-await brain.repairIndex({ rebuild: 'all' })
-```
-
-A family named this way is recorded with `rebuilt: true` and
-`reason: 'explicit rebuild requested'`, and is skipped by the normal
-health-driven pass in the same call — it was already rebuilt unconditionally.
-
-Reach for the explicit door when you need certainty regardless of self-report;
-reach for bare `repairIndex()` for routine maintenance and after any incident
-where you're not sure which family (if any) needs it.
-
-## What `suspect` counts mean
-
-Storage's canonical count ledger increments the ALL-visibility total on every new
-record and decrements it on every *proven* delete — one where the record was read,
-or the caller supplied its prior image. A delete that cannot prove what it removed
-existed doesn't guess: it flags the ledger `suspect` (an operator-visible
-`console.warn`, narrated once per session, not once per delete) rather than risk
-decrementing a total that was never incremented for that record in the first
-place. This is intentionally rare — it's a defensive fallback for callers on an
-unusual removal path, not a per-delete cost.
-
-`suspect` is not directly exposed on any `Brainy` method today — it lives on the
-`StorageAdapter`'s optional `getCanonicalCounts()`, primarily consulted by
-`repairIndex()`'s recount step and by custom storage adapters composing their own
-`healthReport()`. What matters for an application: a `suspect` ledger is not
-incorrect, just *unverified since the last recount* — and `repairIndex()`'s
-unconditional count-rollup step (step 2, above) recomputes the ALL scalars from a
-real canonical walk on every call, clearing the flag with proof either way.
-
-## Practical guidance
-
-- **On a normal restart**, do nothing — `init()` brings every provider to
-  serving before it returns, or fails loudly.
-- **On a `*NotReadyError`** from a live read, reconcile with `repairIndex()`
-  (report-driven is almost always sufficient) and retry.
-- **After an incident** where you distrust a specific family regardless of what
-  it reports healthy — a storage-layer fault, a suspicious restore — use the
-  explicit door: `repairIndex({ rebuild: ['metadata' | 'graph' | 'vector'] })`.
-- **To audit before trusting a report**, `brain.auditGraph()` walks every stored
-  relationship and proves (or disproves) that reads return canonical truth,
-  independent of what any provider self-reports — see
-  [Inspecting a Live Brainy](../guides/inspection.md).

-# External Backups & Sparse Storage
-
-The built-in snapshot path — [`db.persist()` and `brain.restore()`](/docs/guides/snapshots-and-time-travel) —
-already handles everything on this page for you. Read this when you back up a brain directory with
-**external tools**: `tar`, `rsync`, `cp`, `scp`, or a filesystem-level backup agent.
-
-## The one-sentence rule
-
-> **Always use the sparse-aware flag**: `tar czSf` (capital `S`), `rsync --sparse`,
-> `cp --sparse=always`. A naive copy can turn a 2 GB store into a 100+ GB one — or fail
-> the disk entirely.
-
-## Why: some files are sparse
-
-When a native accelerator plugin is active, parts of the index live in **memory-mapped files**
-created at a large fixed virtual size — the file's *apparent* size — while the filesystem only
-allocates blocks that were actually written. A brand-new id-mapper file can report tens of
-gigabytes in `ls -l` while occupying a few megabytes on disk.
-
-Check the difference yourself:
-
-```bash
-ls -lh  brain-data/_id_mapper/    # APPARENT size (can be huge)
-du -sh  brain-data/               # ALLOCATED size (the real footprint)
-```
-
-The sparse candidates in a brain directory:
-
-| Path | What it is |
-|---|---|
-| `_id_mapper/` | The native id-mapper's mmap files (large fixed virtual size) |
-| `_blobs/` | Native index files (vector base, segments) — may be mmap-backed |
-
-Everything else (entities, `_system`, `_generations`, `_cas` content blobs) is ordinary dense data.
-
-## Doing it right
-
-**tar** — the `S` flag detects holes and stores only real data:
-
-```bash
-tar czSf brain-backup.tgz /data/brain
-# restore preserves the holes:
-tar xzSf brain-backup.tgz -C /data/
-```
-
-**rsync**:
-
-```bash
-rsync -a --sparse /data/brain/ backup-host:/backups/brain/
-```
-
-**cp**:
-
-```bash
-cp -a --sparse=always /data/brain /backups/brain
-```
-
-**What goes wrong without the flag:** the copy *materializes* every hole as real zero bytes.
-A store whose apparent size exceeds the target disk fails with `ENOSPC` partway through — and a
-copy that *does* fit silently costs the full apparent size in storage and transfer time.
-
-## What the built-in paths do (so you don't have to)
-
-- **`db.persist(path)`** snapshots via **hard links** — instant and space-shared, since every data
-  file is immutable-by-rename. The handful of append-in-place files (the transaction log, the
-  commit fact log's tail segment) and mmap-mutated directories (`_id_mapper/`) are **byte-copied**
-  instead, so a post-snapshot write can never reach through a shared inode into your backup.
-- **`brain.restore(path, { confirm: true })`** is **non-destructive and sparse-aware**: the snapshot
-  is copied into a staging area *before* any live data is touched (all-zero blocks stay holes), and
-  only after the copy fully succeeds does an atomic swap move it into place. A failed copy —
-  including `ENOSPC` — leaves the live store exactly as it was. A crash mid-swap completes forward
-  on the next open.
-
-## Live-store caveats for external tools
-
-1. **Prefer snapshotting a `persist()` output, not the live directory.** `persist()` produces a
-   crash-consistent, immutable snapshot; running `tar` against a live, actively-written directory
-   can capture a torn mid-write state. If you must archive live, stop writes first (or accept that
-   the archive is only as consistent as the moment's flush state).
-2. **Never prune or "clean up" files inside a brain directory.** Index files that look stale or
-   redundant are load-bearing; the store protects its declared index families from in-process
-   deletion, but an external `rm` bypasses that fence. If space is the concern, `du -sh` first —
-   the allocated size is usually far smaller than it looks.
-3. **Verify restores by opening them.** `Brainy.load(path)` opens any snapshot or restored
-   directory read-only — the store verifies its own coherence at open and reports loudly if
-   anything is missing or torn.

-description: The simple story of the 9.0 field-addressing change and the mechanical checklist for updating your call sites — every miss fails loudly with the fix in the error.
-next:
-  - concepts/field-addressing
----
-
-# Migrating to 9.0 — your fields and system fields
-
-The one-sentence version: **your data's field names are now completely
-yours, the engine's own fields all live behind one `system.` prefix, and
-nothing in between can silently go wrong anymore.**
-
-## What changed, simply
-
-**1. Any field name just works.** Before 9.0 the engine quietly owned
-certain names. A field called `level` could be shadowed by the engine's
-internal index layer of the same name (sorts silently returned insertion
-order); names like `confidence` or `subtype` were rejected inside
-`metadata`; names like `content` or `id` were silently never indexed, so
-filtering on them returned nothing. All of that is gone. Any name —
-`level`, `confidence`, `type`, `id`, `content`, anything — is stored
-exactly as written and works with every feature: filtering, sorting,
-grouping, aggregation, search, and time-travel reads.
-
-**2. The engine's fields moved behind `system.`.** The engine still keeps
-its own per-record bookkeeping — creation time, type, confidence, and so
-on. Those are reached one way only now: spelled out, e.g.
-`system.createdAt`, `system.type`. They are just as queryable and sortable
-as before. `orderBy: 'createdAt'` means *your* field named `createdAt`;
-`orderBy: 'system.createdAt'` means the engine's timestamp. No guessing,
-no priority rules.
-
-**3. Storage keeps the two physically separate.** New records store your
-metadata in its own nested compartment, so a user field named
-`confidence` and the engine's confidence live side by side, both intact,
-through restarts, index rebuilds, and `asOf()` history. Old records stay
-readable forever; nothing rewrites your data.
-
-**4. Mistakes are loud.** An ambiguous or unknown field name is a typed
-error naming the fix. Unimplemented options refuse instead of being
-ignored. The only forbidden name in your metadata is one literally
-starting with `system.`.
-
-## The mechanical checklist
-
-Every missed site fails **loudly** with the correction in the error
-message — nothing silently changes meaning. Sweep these patterns:
-
-| Before (8.x) | After (9.0) |
-|---|---|
-| `orderBy: 'createdAt'` (meaning the engine timestamp) | `orderBy: 'system.createdAt'` |
-| `where: { subtype: 'invoice' }` (the engine subtype) | `where: { 'system.subtype': 'invoice' }` |
-| `where: { confidence: { greaterThan: 0.8 } }` (the engine scalar) | `where: { 'system.confidence': { greaterThan: 0.8 } }` |
-| `groupBy: ['noun']` or `groupBy: ['type']` | `groupBy: ['system.type']` |
-| `where: { visibility: 'internal' }` / `{ service: … }` (engine values) | `'system.visibility'` / `'system.service'` |
-| `metadata: { confidence: 0.9 }` expecting a throw or a lift to the engine scalar | it is YOUR field now — set the engine scalar via the `confidence` param |
-| `new Brainy({ reservedFieldPolicy: … })` | remove the option (it throws with this note) |
-| `find({ cursor })` / `includeRelations` / `writeOnly` | refuse with `UnsupportedFindOptionError` — they were silently ignored before |
-
-If a bare name in a query was genuinely *your* field all along (`orderBy:
-'score'`, `where: { status: 'active' }`), **change nothing** — bare names
-mean your fields, always.
-
-## What happens at first open
-
-Each existing database rebuilds its derived indexes once, automatically,
-at the first open on 9.0 (index epoch 3 — the index keys split the two
-namespaces). One-time cost, observable via `getIndexStatus()`; no manual
-step, and your stored data is not modified.
-
-## For tooling and raw-record readers
-
-If you read raw stored records (fact-log scanners, export tooling), use
-the exported shape-aware splitters — they handle both record eras:
-
-```typescript
-import { splitNounMetadataRecord } from '@soulcraftlabs/brainy'
-const { reserved, custom } = splitNounMetadataRecord(rawRecord)
-// reserved = engine fields · custom = the user's bag, ANY names
-```
-
-Feature detection (never version-sniff):
-
-```typescript
-import * as brainy from '@soulcraftlabs/brainy'
-const lawActive = 'FIELD_ADDRESSING_CAPABILITY' in brainy // 'field-addressing/v1'
-```
-
-## Where to go next
-
-- [Field addressing](../concepts/field-addressing.md) — the full contract:
-  the ten system scalars, the relation mirror, refusal semantics, and the
-  cross-engine ordering guarantees.

@@ -180,35 +180,3 @@ Brainy 8.0 has exactly two write-coordination counters, at two granularities:
 They compose: a `transact()` batch can carry per-entity `ifRev` checks *and* a whole-store `ifAtGeneration`; any failed check rejects the entire batch before anything is staged. Generations also power snapshots and time travel (`brain.now()`, `brain.asOf()`, `db.persist()`) — see the [consistency model](../concepts/consistency-model.md) and [Snapshots & Time Travel](./snapshots-and-time-travel.md).
 
 A snapshot or historical view captures each entity *including* its `_rev` at that moment, so reading the past and writing back with `ifRev` against the live state works exactly as you'd hope: the write fails if the entity moved since the state you copied from.
-
-## The transact envelope: batch size, budget, and bulk imports
-
-`transact()` applies its batch atomically under one commit — which means the whole batch
-shares one **apply budget**. Since 8.7.0 the budget scales with the batch:
-`max(30 s, opCount × 2 s)`, or exactly what you pass as `timeoutMs`. A tripped budget rolls
-the entire batch back (nothing partial survives) and throws a retryable
-`TransactionTimeoutError` that names the operation it stopped at, the batch size, and the
-elapsed vs budgeted time — a diagnosis, not just a failure:
-
-```
-Transaction timed out at operation 41/120 ('add') — 246012ms elapsed, budget 240000ms.
-The batch rolled back atomically; retry with a higher timeoutMs or a smaller batch.
-```
-
-Practical envelope guidance for bulk work:
-
-1. **Precompute embeddings outside the commit path.** Embedding inside `transact()` spends
-   the budget on model inference. Use `brain.embedBatch(texts)` and pass each vector via
-   the op's `vector` field — the commit then pays only storage costs, and a retried batch
-   never re-pays inference. (The win is *where* the inference happens, not raw embedding
-   throughput: on the default WASM engine, batch and sequential embedding measure
-   comparably, ~160 ms/text; native embedding providers may batch faster.)
-2. **Chunk very large imports** into batches of a few hundred ops with one `transact()`
-   each. You lose whole-import atomicity but keep per-chunk atomicity, bounded memory, and
-   resumability — pair with `ifAbsent` upserts so a retried chunk is idempotent.
-3. **Slow disks change the math, not the contract.** On network-attached storage a single
-   op can cost ~2 s (canonical write + fsync + index maintenance). The scaled default
-   absorbs that; pass an explicit `timeoutMs` only when you know better than the scale.
-4. **`addMany`/`relateMany` are the convenience tier** — they chunk and batch-embed for
-   you, with per-item error reporting instead of batch atomicity. Choose by what you need:
-   atomic-all-or-nothing → `transact()`; resilient bulk load → `addMany`.

-## LC — Lifecycle
-
-| ID | Brainy row | Status |
-|----|-----------|--------|
-| LC1 | Same-version reopen adopts everything: brain-format epoch match → zero rebuilds; aggregation state adopts by stamp; persisted indexes load. | ✅ `tests/unit/brainy/brain-format-handshake` + `migration-deference` (no-drift reopen never rebuilds) |
-| LC2 | New empty brain: doors immediate. | ✅ exercised by every suite's setup |
-| LC3 | Upgrade, same epoch: as LC1 — new code on unchanged formats owes nothing at open. | ✅ same pins as LC1 (epoch equality is the gate) |
-| LC4 | Upgrade with epoch migration: TODAY brainy's epoch rebuild runs at open before doors. | 🔴 **owed — the sev's lockout row.** The doors-open-serving-old-structures design (yielding installments + atomic swap) lands measured-and-gated behind the service-class pair, per the lifecycle-sprint choreography. Acceptance case: the 9,184-row hours-lockout. |
-| LC5 | Crash recovery: bounded, resumable, narrated. Aggregation leg ✅ (behind-stamp → incremental catch-up off the fact log + time-travel reconciliation, capped at 5,000 affected before an ANNOUNCED rescan). Vector/metadata legs ride epoch machinery (rebuild-from-canonical, narrated). | 🟡 aggregation pinned (`tests/integration/aggregation-lifecycle-catchup`); the rebuild legs are narrated but not yet installment-yielding (couples to LC4) |
-| LC6 | Shutdown under load: close() drains the background flush flight, tears down cadence timers, runs ONE time-bounded compaction pass (~5s budget, resumable). | 🟡 pinned for flush/compaction (8.9.0 suites); SIGTERM drain budget not yet declared |
-| LC7 | Rollback/downgrade: an N−1 build opening an N brain. | 🔴 owed — no declared read-compat window or typed refusal today (epoch mismatch triggers a rebuild, not a refusal; v2 nested-bag records read as a phantom user field on pre-law builds). Needs the declared-window contract. |
-| LC8 | Relocatable brain directory: no absolute paths in artifacts; persist()/load() round-trips. | 🟡 persist/load pinned; byte-for-byte relocation depot cases are the pair gate's (shared corpora) |

-| DP1 | `get()` by id: direct storage read + hydrate. INDEX-SERVED (id-mapped). Milliseconds at every scale. | ✅ exercised everywhere; budget rides the pair speed table |
-| DP2 | `find({query})`: embed + vector search. The embed dominates (native side owns the budget); JS HNSW serves the search leg. | 🟡 300ms-class p95 is the pair speed-table row; brainy-alone budget declared there |
-| DP3 | Filtered/sorted list: column top-K when the field is columnized (INDEX-SERVED, zero canonical reads on the sorted page — value pairs come from ONE batched metadata-record pass); no-column fallback is BOUNDED-ANNOUNCED (one batch pass, announces once per field past 500 rows); unknown field → TYPED REFUSAL naming both candidate spellings. | ✅ `tests/unit/utils/metadataIndex-sort-callshape` (zero per-row reads, batch-only — latency-blind) + `metadataIndex-nested-orderby` (dotted keys serve-or-refuse) + `tests/integration/orderby-sort-bug` |
-| DP4 | Aggregation/stats: ALWAYS answers. Write-time incremental; behind-stamp reconciles incrementally; genuine rebuilds go through the native parallel door or the paged JS walk; nothing ever latches off; before-image-less deletes flag a LOUD rescan, never a silent skip. | ✅ `tests/integration/aggregation-lifecycle-catchup` + `tests/unit/aggregation/aggregation-provider-rebuild` |
-| DP5 | Graph traversal: `related()` paged via adjacency; whole-graph analytics carry declared cost. | 🟡 paged reads pinned; analytics cost-class declaration owed (rides VENUE-GRAPH-TRUST audit tool) |
-| DP6 | Single write: ack at the canonical commit; visibility committed at ack (the atomic vector update kills the remove→add dark window); maintenance NEVER holds the ack (background flush cadence — THE ACK LAW pins: a hung flush cannot block a write, a hung EMBEDDER cannot block a write). | ✅ `tests/unit/brainy/persistence-policy` + `tests/unit/hnsw/update-item-atomic` + `tests/integration/deferred-embedding` |
-| DP7 | Bulk ingest: sustained rate holds flat — per-write maintenance taxes must not grow with brain size (A4 removed caller-flush convoys; deferred embedding removes the per-write embed tax where opted). | 🟡 the decay-curve row is a pair speed-table RED GATE; brainy-alone sustained-rate run rides the same corpora |
-| DP8 | Read under write pressure: no flicker window — a row that exists is never invisible to recall, even transiently (same-vector re-index is a no-op; changed-vector swaps in place, node never leaves the index; deferred updates serve the OLD vector until the atomic swap — stale-beats-absent). | ✅ brainy leg pinned (`tests/unit/hnsw/update-item-atomic` 9/9 + `deferred-embedding` stale-beats-absent); the symmetry property suite + runtime sentinels remain the B4 program |
-| — | **As-of semantic recall** (time-travel vector search): `asOf(G).find()` serves the vectors AS THEY STOOD at G — byte-exact past vectors, tombstone masking, the deferred-embed cell honest on the vector leg, TYPED refusal beyond the head. Brainy-alone leg = ephemeral at-generation materialization (documented O(n log n at G) build, bounded); the at-scale leg rides the accelerated provider's as-of index. | ✅ `tests/integration/asof-semantic-recall` 4/4 (registry ID pending the master table's mint) |

-| MT2 | Compaction: never on flush (durability-only law, 8.9.0); close-time pass time-budgeted + resumable; explicit `compactHistory({timeBudgetMs})`. | ✅ 8.9.0 suites |
-| MT3 | Index upkeep (mapper folds, delta promotion): native-side machinery; brainy's JS legs are small and synchronous-cheap. | 🟡 declared; yield audit rides the pair |
-| MT4 | Heal/rebuild walks (`repairIndex`, backfill walks): paged; failure latches with cooldown; NOT yet yield-to-foreground installments. | 🔴 owed — the priority-isolation clause (couples to LC4; same choreography) |
-| MT5 | Deferred embedding worker: ack at durability, durable pending markers (written BEFORE the commit — orphan-safe), crash-recovered at open via a bounded prefix listing, single-flight, 60s hang guard, `awaitPendingEmbeds()` barrier + `pendingEmbeds` gauge. VFS write paths adopt it end-to-end. | ✅ `tests/integration/deferred-embedding` 5/5 |

-## FM — Failure modes
-
-| ID | Brainy row | Status |
-|----|-----------|--------|

-| FM2 | Memory pressure: query limits + reserved-memory config; unified cache eviction. | 🟡 declared budgets; cascade pin owed |
-| FM3 | Torn/corrupt file on open: malformed brain-format marker → safe rebuild (never trusting a bad epoch); corrupt records surface loudly. | 🟡 marker pin ✅ (`brain-format-handshake`); broader quarantine is native-side |
-| FM4 | Native module unavailable: plugin load failure is LOUD (version-coupling law throws on range mismatch — never silently version-drifted); JS engine serves with its own declared budgets, named as the active backend in op names. | ✅ `tests/unit/plugin-version-coupling` + op-name stamping |
-
-## FL — Fleet
-
-| ID | Brainy row | Status |
-|----|-----------|--------|
-| FL1 | Cold open on demand: LC1's adopt-everything open; warm() available for eager paths. | 🟡 open cost pinned at LC1; millisecond budget rides the speed table |
-| FL2–FL4 | Boot storm / upgrade wave / isolation: fleet-layer policies over LC1/LC4 — engine leg = budgeted opens + LC4's behind-doors migration. | 🔴 owed with LC4 |
-| FL5 | Brain as product object: create instant (LC2) · erase = `clear()` explicit + complete · export = portable-graph, canon-complete mode available. | ✅ clear-persistence + portable-graph + canonical-enumeration suites |

-description: Measured per-operation latency envelopes at stated scales — what to expect, on what hardware, and exactly how each number was produced.
-next:
-  - guides/find-limits
----
-
-# Performance Envelopes
-
-Every number on this page is **measured, never projected** — produced by the script
-cited at the bottom, against the built package (the artifact you install), on the stated
-hardware. Each entry says what was measured, at what scale, on which storage backend.
-When a release touches a measured path, that operation is re-measured and this page
-updates in the same release.
-
-Two scopes to keep straight:
-
-- **These envelopes are the pure-JS engine** (no native accelerator registered) on
-  filesystem storage. This is the floor every deployment gets from `npm install` alone.
-- **Accelerated deployments** (the optional native provider) publish their own numbers —
-  this page never claims them.
-
-## Read operations
-
-Reads are where the architecture pays off: after the write path has done its indexing
-work, queries answer from purpose-built indexes without scanning.
-
-| Operation | 1,000 entities | 10,000 entities | Notes |
-|---|---|---|---|
-| `get(id)` (warm) | p50 < 0.1ms | p50 < 0.1ms | served from cache/metadata index |
-| `find` (metadata: indexed equality + range, limit 100) | p50 1.0ms · p95 1.8ms | p50 7.0ms · p95 8.9ms | column-store bitmap paths |
-| `related(id)` (per-node adjacency) | p50 < 0.1ms · p95 0.2ms | p50 < 0.1ms | LSM adjacency index — O(degree), scale-independent |
-| `find` (semantic: embed + HNSW, 1k docs) | p50 178ms · p95 393ms | — | dominated by WASM query embedding (measured on a machine under concurrent load — treat the p95 as an upper bound); the vector search itself is single-digit ms |
-
-## Write operations
-
-Under Model-B **every write is its own durable generation** — a single-op `add` pays
-serialization, before-image staging, and fsync before it acks. That durability is priced
-into the write path visibly, by design:
-
-| Operation | 1,000 entities | 10,000 entities | Notes |
-|---|---|---|---|
-| `add` (single-op) | p50 167ms · p95 171ms | p50 165ms · p95 172ms | full durable generation per write — flat across scale |
-| `addMany` (bulk) | ~163ms/entity | ~187ms/entity | **currently per-item commits** — see the honest note below |
-| `relateMany` | ~0.8ms/edge | ~0.9ms/edge | edges batch efficiently today |
-| `flush` (steady-state, 1 pending write) | p50 8ms · p95 10ms | p50 45ms · p95 52ms | durability-only since 8.9.0 — cost no longer depends on history backlog or retention mode |
-
-**The honest note on bulk writes:** `addMany` today commits each item as its own
-generation (the same durability as single-op `add`, serialized by the single-writer
-lock), so bulk-load cost is N × single-op cost. Batched chunk commits (one generation
-and one fsync window per chunk, as `removeMany` already does) are designed into the
-unified-commit work on the current roadmap. Until that ships, size bulk imports
-accordingly — 10k entities is minutes, not seconds, on filesystem storage.
-
-## Open / close
-
-| Operation | 1,000 entities | 10,000 entities | Notes |
-|---|---|---|---|
-| `open` (empty store) | ~560ms | ~190ms | includes embedder initialization |
-| `open` (warm, populated, clean shutdown) | 763ms | 4.9s | pure-JS vector index load dominates and grows with entity count; the native accelerator exists precisely to remove this |
-| `close` | bounded | bounded | auto-compaction pass is time-bounded (~5s max) since 8.9.0 |
-
-A store that was NOT cleanly closed pays index rebuilds on top of the warm-open
-number (tens of seconds at 10k) — clean shutdown is worth engineering for.
-
-## How these were produced
-
-- **Hardware**: Intel Core i9-14900HX (32 threads), 62GB RAM, NVMe, Linux, Node v22.
-- **Backend**: `storage: { type: 'filesystem' }`, pure JS (no native providers).
-- **Embeddings**: deterministic stub for non-semantic ops (isolates engine cost);
-  the real WASM embedder for the semantic row (that's what you'll run).
-- **Method**: p50/p95 over 50–200 samples per op against the built `dist/`;
-  the measuring script ships in the repo history and re-runs per release.
-
-Numbers on different hardware will differ; the *shape* (sub-2ms indexed reads,
-~160ms embedding-bound semantic queries, durability-priced writes) is the envelope
-you should hold your deployment against. If your measurements diverge from these
-shapes by an order of magnitude, something is wrong — file it.

-# Gate Guards
-
-Two standalone scripts that stand between a test/build gate and a false
-verdict: one refuses to let the gate start on a noisy machine, the other
-refuses to let a truncated or crashed vitest run be read as green.
-
-## Why these exist
-
-Both guards exist because of the 2026-08-13 lost-day ledger: a gate ran on
-a machine under load, and separately a vitest worker pool died mid-suite
-while still printing a plausible-looking summary line, and in both cases
-the bad result was trusted and acted on for the better part of a day before
-anyone noticed. Neither failure mode announces itself — a loaded machine
-still finishes and reports numbers, and a truncated test run still prints a
-`Test Files` / `Tests` line — so both guards check the evidence explicitly
-rather than trusting that a gate finishing means the gate was valid.
-
-## gate-preflight.sh
-
-Run before any gate lane starts. Exits 1 the moment the machine isn't
-gate-clean, with one `FATAL:` line per violation naming the exact offender
-(the pid and command, the path, the measured value). Prints one `OK:` line
-per check that passes. `WARNING:` lines mark checks that were skipped, not
-failures.
-
-Checks:
-
-| # | Check | Default threshold | Override |
-|---|-------|--------------------|----------|
-| a | 1-minute load average | `nproc / 2` | `GATE_MAX_LOAD` |
-| b | any non-allowlisted process over 50% of one core | 50% | `GATE_ALLOW_REGEX` (extra pattern matched against the process's args) |
-| c | cpu0 scaling governor must be `performance` | — | none (warns and skips if the sysfs path is absent) |
-| d | free space on `/` and `/tmp` | 10G each | `GATE_SKIP_DISK_CHECK=1` to skip entirely |
-
-The allowlist for check (b) is always: this script's own process tree
-(its ancestors and its direct child processes), `sshd`, `systemd`, and
-kernel threads (recognizable by args wrapped in brackets, e.g.
-`[kworker/0:1]`). `GATE_ALLOW_REGEX` extends it — it does not replace it.
-
-## vitest-verdict-check.sh
-
-Run after every vitest lane, against that lane's captured log. Fails
-loudly, quoting the exact line or string that tripped it, when the log's
-own summary can't be trusted:
-
-- no `Test Files` (or, in `--count-tests` mode, `Tests`) summary line is
-  present at all
-- the parenthesized total in that line doesn't match what was expected
-- fewer files/tests are accounted for (passed + failed + skipped) than the
-  total claims — a truncated run
-- the log contains `Unhandled Error` or `Timeout calling` anywhere — a dead
-  worker pool, regardless of what the summary line claims
-
-```
-vitest-verdict-check.sh <log-file> <expected-file-count>
-vitest-verdict-check.sh --count-tests <log-file> <minimum-test-count>
-```
-
-The first form checks `Test Files` for an exact match. The second checks
-`Tests` for a minimum (a floor, not an exact count, since the total number
-of individual tests moves more often than the number of test files).
-
-## Wiring into a CI lane
-
-```sh
-# Before any lane that will report a verdict:
-scripts/gate/gate-preflight.sh || exit 1
-
-# Run the suite, capturing its output:
-npx vitest run tests/unit 2>&1 | tee /tmp/unit.log
-
-# After every vitest lane, check the log against the actual file count:
-EXPECTED_FILES=$(ls tests/unit/**/*.test.ts | wc -l)
-scripts/gate/vitest-verdict-check.sh /tmp/unit.log "$EXPECTED_FILES" || exit 1
-```
-
-## Exit-code contract
-
-| Script | Exit 0 | Exit 1 |
-|--------|--------|--------|
-| `gate-preflight.sh` | machine is gate-clean | one or more `FATAL:` violations printed |
-| `vitest-verdict-check.sh` | log's summary is trustworthy and matches | usage error, missing/unreadable log, or one or more `FATAL:` violations printed |
-
-Non-zero from either script means: do not trust the gate that was about to
-run, or the result of the one that just ran.

- * @description Push this repo's PUBLIC docs to the soulcraft.com docs ingest
- * door after an npm publish (VENUE-DOCS-RELEASE-PUSH — retires the old
- * build-time docs sync).
- *
- * Contract (mirrors the reference implementation on the serving side):
- *   POST {base}/api/docs/ingest
- *   headers: x-service-secret: $DOCS_INGEST_SECRET, Content-Type: application/json
- *   body: { docs: [{ slug, title, markdown, nav: { order, section } }] }
- *   batches of 10, idempotent per slug.
- *
- * A doc is public iff its frontmatter has `public: true` AND a `slug`. The
- * frontmatter is stripped; `category` → nav.section, `order` → nav.order.
- *
- * Deliberately NOT pushed: the combined /docs landing index. It spans BOTH
- * engine corpora (this repo's and the native accelerator's), so a per-repo
- * push would clobber the union — the index is authored on the serving side.
- *
- * Env: DOCS_INGEST_SECRET (required), DOCS_INGEST_BASE (default
- * https://soulcraft.com). Exits 0 with a LOUD warning when the secret is
- * absent (the npm publish has already happened; the serving side runs its
- * interim sync on request) and exits 1 when a push actually fails — the docs
- * site would silently trail npm otherwise, and that must be visible.

- *
- * - `seg-<firstGen, zero-padded 20>.bgs` — magic "BGS1", then one frame per
- *   generation: `u32 payloadLen | u32 crc32c | msgpack payload`. Payload is

- *   (bit 0 = compressed payload — v1 always 0; a future writer upgrade,
- *   never a format break). Sealed segments are IMMUTABLE — the fact log's
- *   own law, generalized.
- * - `seg-<firstGen>.idx` — DERIVED sidecar (msgpack): per-generation frame
- *   offsets (point reads = one ranged read, never a listing) + per-id
- *   generation postings (per-id chain rebuilds read only what they need).
- *   Corrupt/missing → rebuilt from its segment in one sequential read,

- * - `manifest.json` — the segment catalogue + `compactedBelow` (D3's

- *
- * D3 semantics carried here: bounded-retention reclaim drops WHOLE segments

- * @module db/logAuthority
- * @description The per-brain LOG-AUTHORITY SWITCH and its verification
- * oracle — the guarded adoption path for log-canonical storage.
- *
- * Two storage authorities exist during the adoption window:
- * - `'tree'` (the default, today's behavior): the canonical record tree is
- *   authoritative; the generation log is a complete dual-written journal.
- * - `'log'`: the generation log is authoritative for this brain; single-op
- *   write acks await a covering log fsync (durable-at-ack), and derived
- *   state treats the log as ground truth.
- *
- * THE SWITCH IS PER BRAIN, STORED, CHECKED AT OPEN ONLY, and ONE-DIRECTIONAL
- * unless explicitly reverted by an operator. A brain flips ONLY when its
- * verification oracle is green: a full replay-and-diff of the log against
- * the still-authoritative tree (the read-only witness). The oracle failing
- * NAMES every divergence — a brain with pre-log history (records the log
- * never saw) reports them as `pre-log-record` mismatches and needs a
- * baseline backfill before it can ever flip.
- *
- * Nothing in this module mutates data: the oracle is read-only; the flip
- * writes ONE artifact. Reverting = rewriting the artifact to 'tree' (the
- * tree remained authoritative-quality throughout the window by dual-write).
