The 3.0 native engine ships as @soulcraft/cor (brainy 8.x <-> cor 3.x are a
version-matched pair); the old @soulcraft/cortex package stays on the 2.x/7.x
line. Public docs and .d.ts-visible comments now name the correct package.
Historical 2.x contract references (e.g. the 2.3.1 read-side fallback) keep
the old name deliberately.
- find() search-mode: collapsed the two overlapping options to one canonical
`searchMode: SearchMode` (the redundant `mode` alias was silently ignored on
the primary find() path while honored on the historical path — a footgun) and
removed the unwired `explain?` FindParams field (never read by find()).
- Documentation accuracy on the public type surface: entity ids documented as
UUID v7 (auto) / v5 (natural key), not v4; dropped the stale "Brainy 3.0"
banners and "backward compatibility" hedging on the fresh-8.0 Result type;
documented the via/type alias; removed the dead GraphConstraints.bidirectional;
fixed the no-op `EmbeddedGraphVerb = Omit<GraphVerb,'source'>` to omit the real
sourceId; corrected the GraphIndexProvider.isInitialized JSDoc; documented
removeMany's per-chunk generation granularity; JSDoc'd the public VFS surface.
- Honest perf comments in source: removed unmeasured billion-scale figures from
the LSMTree / graphAdjacencyIndex headers (the JS fallback is in-memory after
open; native is the scale path).
- Robustness: getVerbMetadata propagates read errors symmetrically with
getNounMetadata; the find() egress integrity-guard keeps a row when the JS
matcher doesn't implement an operator the provider already matched on; hardened
the boundary-no-native CI guard to catch side-effect imports + re-exports.
- Tests: de-theatricalized a relateMany test to assert the real contract; fixed
a stale Model-B header.

- Version-coupling cold-init: getBrainyVersion() returned a stale build-time
default ('3.14.0') on the FIRST synchronous call — the one loadPlugins() makes
to build context.version — because the package.json read was async. A native
provider declaring a realistic `>=8.0.0` range was therefore rejected on cold
init. version.ts now reads package.json synchronously (8.0 targets Node-like
runtimes only); added a cold-init coupling regression with a `^8.0.0` plugin.
- No-silent-failures on the highest-fan-in read path: getNouns()/getVerbs()
converted a storage read failure into a success-shaped empty page, which the
cold-start rebuild then read as "store empty" and skipped the rebuild — booting
a permanently-empty index with no signal (the same silent-failure class as the
phantom bug). Both now re-throw a named BrainyError; the rebuild path re-throws
read failures (fail loud) and records a queryable degraded state, surfaced via
checkHealth(), for non-fatal rebuild hiccups.
- LSM SSTable leak: graph compaction wrote a merged SSTable but only dropped the
old ones from the manifest, orphaning their payloads forever ("In production
we'd add a cleanup mechanism"). Added StorageAdapter.deleteMetadata() and now
reclaim each compacted-away SSTable.
- Documented the two headline methods add() and find() (the only undocumented
public methods on the class).
Full gate green: build, unit 1512, integration 607.

Pre-GA dead-code sweep. A deterministic import-reachability walk from the
package's real entry points (the exports map, the CLI bin, the conversation
surface) found 34 source modules that nothing reachable imports — they
compile and ship as dist output that no consumer or internal path can ever
reach. All were superseded duplicates, abandoned parallel implementations,
or built-but-never-wired features:
- superseded duplicates of live modules: an older "unified" entry, a
standalone neural-import variant, a static NLP processor + its matcher,
a parallel API-types module, a duplicate progress-types module
- an abandoned import path (orchestrator + entity deduplicator + barrels)
left behind when ingestion moved to the coordinator
- unwired feature modules (instance pool, import presets, cached
embeddings, relationship-confidence scorer) reachable only from tests
- dead leaf utilities (write buffer, deleted-items index, bounded
registry, two crypto shims, a cache manager, a structured logger, a
stale v5 type-migration helper, a browser-only FS type shim) and
several dead re-export barrels
- a CLI catalog command wired into no command
Also removed two tests that only exercised deleted modules, repointed two
VFS tests off a deleted barrel onto the implementation module, and deleted
one example that demoed removed features.
Verified: clean build (both tsc passes), unit 1505 + integration 607 green,
and a re-run of the reachability walk reports zero remaining orphans.

Adds three intent-level graph reads to the `brain.graph` namespace, each
native-dispatched to the optional `@soulcraft/cor` 3.0 graph engine when present
and served from pure-TS kernels otherwise (identical public shapes, default
visibility filter respected on both paths):
- `rank(opts?)` → `{ id, score }[]` descending — importance / centrality.
TS fallback: PageRank power-iteration with dangling-mass redistribution.
- `communities(opts?)` → `{ groups, count }` — connected grouping. TS fallback:
union-find weakly-connected components, or iterative Tarjan SCC when
`{ directed: true }`.
- `path(from, to, opts?)` → `{ nodes, relationships, cost } | null` — best route.
TS fallback: BFS for fewest hops, Dijkstra (min-heap) for least summed edge
weight (`by: 'weight'`); on-demand frontier expansion so short paths terminate
early. `direction` / `type` / `maxDepth` filters apply.
These are intent contracts, not algorithm contracts — the question is the
promise, the algorithm is the engine's choice.
Pure kernels live in src/graph/analyticsFallback.ts (PageRank, connected
components, Tarjan SCC, MinHeap) — unit-tested in isolation. The full surface is
tested end-to-end through the TS fallback, and the native dispatch + int↔uuid
hydration paths are covered by a mock provider in graph-native-routing.

Graph time-travel needs an edge's existence recorded per generation so
db.asOf(g) hops resolve historically correct endpoints. The metadata layer
already threads brainy's commit generation per write; the graph write path did
not, leaving a versioned verb-endpoint store unable to answer "which edges
existed at generation g".
- GraphIndexProvider.addVerb/removeVerb gain a `generation: bigint` parameter
(the same watermark the storage layer stamps onto the record). A provider with
a per-generation edge chain stamps the edge at that generation; the JS baseline
has no such chain and accepts-and-ignores it — graph time-travel is a
native-provider capability, and the open-core path serves edges as-of-now (the
one documented graph time-travel limitation).
- The two graph transaction operations resolve the generation via a thunk at
EXECUTE time: the generation store assigns the batch generation only once the
commit begins executing, after the operations are planned. The same generation
is reused for an operation's rollback half.
- All graph-write call sites pass the in-flight generation.
Adds a spy-provider test proving the threading, execute-time resolution, and
forward/rollback generation reuse. The JS index ignores the value, so behaviour
is unchanged: unit 1402/1402, db-mvcc 25/25, bigint-contract relate/unrelate 10/10.
- brain.fillSubtypes(rules): idempotent subtype back-fill for pre-8.0 data.
One rule per NounType/VerbType (literal default or per-entry function);
fills only entries still missing a subtype through the public update()/
updateRelation() paths; returns { scanned, filled, skipped, errors, byType }.
Full unit suite in tests/unit/brainy/fill-subtypes.test.ts.
- Fix getNouns/getVerbs pagination hasMore (peek one past the window) —
was permanently false, silently truncating every multi-page walk.
- find({ near }) without near.id now throws a teaching error instead of an
opaque storage sharding failure; CLI --threshold without --near applies a
plain score floor.
- CLI init/close audit: every one-shot command init()s, close()s, and exits
explicitly; delete the unmaintained interactive REPL; replace the cloud-era
storage subcommands with status/batch-delete; new types/validate commands.
- requireSubtype JSDoc now documents the 8.0 default-on contract; audit()
recommendation points at fillSubtypes.
- Docs: data-storage-architecture rewritten to the real 8.0 on-disk layout;
README storage section reflects filesystem+memory and snapshots; eli5 and
SEMANTIC_VFS /as-of/ semantics corrected; internal tracker IDs and
.strategy references scrubbed from published files.
Historical Db values (now()/asOf() pins that history has moved past) now
serve the COMPLETE query surface - vector/hybrid search, graph traversal,
cursor pagination, and aggregation - by materializing ephemeral in-memory
indexes over the exact at-generation record set. The historical-query
throw is gone; NotYetSupportedAtHistoricalGenerationError is deleted.
Materializer (Brainy.materializeAtGeneration):
- Copies the at-G record set (live bytes for ids untouched since the pin,
immutable before-images otherwise) into a fresh MemoryStorage; a final
reconciliation pass under the commit mutex makes the copy exact even
when transactions commit mid-build.
- Opens a read-only Brainy over the copy: init rebuilds the metadata and
graph-adjacency indexes from the records; the vector index is built by
inserting every at-G vector (the at-G HNSW graph never existed on disk,
so there is nothing to restore). Host embedder and aggregate definitions
are shared - no second model load, aggregates backfill at-G values.
- Cost is the documented contract: O(n at G) time and memory, ONCE per Db
(handle cached; freed by release(), with a FinalizationRegistry backstop
that also closes leaked readers). A native VersionedIndexProvider serves
the same reads from retained segments with no rebuild.
Db routing (src/db/db.ts): metadata-level find()/related() keep the free
record path; index-only dimensions (query/vector/near/connected/cursor/
aggregate/includeRelations/non-metadata modes) route to the cached
materialization; unsupported where-operators on the record path re-route
there too instead of erroring. Speculative with() overlays keep the one
honest boundary - SpeculativeOverlayError (overlay entities carry no
embeddings, so index reads over them would be silently incomplete);
metadata find()/get()/filter related() work on overlays.
UpdateParams.vector contract now honored: an explicit pre-computed vector
applies directly (with dimension validation) in update() and transact
update ops, re-indexing HNSW - previously it was silently ignored unless
data also changed.
GraphAdjacencyIndex: adjacency now derives from the two verb-id LSM trees
filtered through the live-verb tombstone set (entity->entity edge trees
deleted - they carried no verb ids, so removeVerb could never tombstone
them and traversal served stale neighbors forever). Neighbor reads batch-
load live verbs via the unified cache; addVerb seeds the cache.
Proofs (tests/integration/db-mvcc.test.ts, 24 green): historical vector
search finds old vector placement including since-deleted entities;
historical graph traversal walks the old wiring after a rewire; historical
aggregation computes at-G group values; asOf() pins get the same surface;
the materialization builds once per Db and release() closes the ephemeral
reader (it refuses reads afterwards); overlays throw the documented error.
ADR-001 updated to the no-throws historical model.
GraphIndexProvider now speaks BigInt at the boundary (D.2 mirror):
- getNeighbors/getVerbIdsBySource/getVerbIdsByTarget take entity ints and
return entity/verb ints as bigint[]
- new REQUIRED verbIntsToIds(bigint[]) batch reverse resolver (L.7
identity-fingerprint design — verb ids are UUIDs by contract, so the
provider-side interning is losslessly reversible)
- addVerb(verb, sourceInt, targetInt) returns the interned verb int;
removeVerb(verbId) joins the contract
Coordinator (brainy.ts) owns ALL UUID <-> int conversion: getOrAssign on
writes, getInt on reads (unmapped UUID -> empty result without calling the
provider), getUuid / verbIntsToIds on returns, plus a bounded ~100k-entry
insertion-order warm cache for verb-int -> verb-id pairs fed by addVerb
returns and resolver results. GraphVerb gains derived sourceInt/targetInt
(populated at add time, never persisted). findConnectedSubtype gains a
native fast path that routes single-type single-subtype outgoing BFS
through the provider when available.
JS GraphAdjacencyIndex satisfies the contract while staying string/u32-keyed
internally: entity ints resolve through the shared entity-id mapper (threaded
in by the coordinator on init/fork/checkout), verb ints come from an
in-process append-only interning map re-derived from storage on
rebuild/cold-start. ColumnStoreProvider widens the same way: addEntity/
removeEntity take bigint, sortTopK/filteredSortTopK return bigint[].
relate() now rejects a caller-supplied id with a teaching error — verb ids
are brainy-generated UUIDs by contract in 8.0 (previously a passed id was
silently ignored). No Roaring64 provider-boundary decode site exists yet;
the JS-internal column store stays Roaring32 and the Treemap decoder lands
with the first consumer of provider-returned filter buffers.
Public brain API unchanged. 1413 tests green (+10 new BigInt contract tests).
PHASE A — every @deprecated marker resolved (~25 removed)
src/coreTypes.ts
- GraphVerb: dropped the "@deprecated Will be replaced by HNSWVerbWithMetadata"
note. GraphVerb IS the canonical contract — every public API path speaks
it. Removed the `source` and `target` legacy alias fields (renamed `from`
/ `to` callers years ago; no consumers remain).
- StorageAdapter: dropped the "@deprecated Use getNouns() with filter" notes
from `getNounsByNounType`, `getVerbsBySource`, `getVerbsByTarget`,
`getVerbsByType`. They were never deprecated in spirit — they're useful
non-paginated convenience wrappers over the paginated `getNouns()` /
`getVerbs()` surface. Refreshed JSDoc to explain the role.
src/types/graphTypes.ts
- Mirrored the GraphVerb cleanup: dropped `source` + `target` legacy aliases.
sourceId + targetId are the canonical fields.
src/import/ImportCoordinator.ts
- Deleted the entire DeprecatedImportOptions interface block (130 LOC). It
was a v3 → v4 migration tool using the `?: never` trick to force
compile errors on dropped options. Five major versions in, the
forced-error gate is no longer pulling its weight.
src/triple/TripleIntelligence.ts
- Deleted `TripleIntelligenceEngine = any` alias. No consumers; superseded
by `TripleIntelligenceSystem`.
src/storage/cow/binaryDataCodec.ts
- Deleted `wrapBinaryData()`. The COW dispatch layer in `baseStorage.ts`
routes by key-prefix convention; the old guess-by-JSON-parse codec was
fragile (compressed bytes can accidentally parse as JSON) and unused.
src/storage/baseStorage.ts
- Refreshed JSDoc on `convertHNSWVerbToGraphVerb()` — the method is alive
and used internally; the deprecation note was stale.
src/embeddings/wasm/AssetLoader.ts → DELETED
- File was @deprecated since model weights moved into the Candle WASM
bundle. No consumers. Removed from `embeddings/wasm/index.ts` exports.
src/embeddings/wasm/types.ts
- Dropped @deprecated tags on `TokenizerConfig` + `TokenizedInput` — still
used by `WordPieceTokenizer` (auxiliary tokenization). Deleted
`InferenceConfig` (truly dead). Updated `embeddings/wasm/index.ts`
exports.
src/utils/metadataIndex.ts
- Deleted `getIdsForCriteria()` — pure alias for `getIdsForFilter()`, no
consumers.
src/interfaces/IIndex.ts
- Removed RebuildOptions.lazy (deprecated and unused; lazy mode is auto-
selected by available-memory detection).
src/hnsw/hnswIndex.ts
- Removed `getNouns()` (returned a full Map; deprecated in favor of
pagination years ago and no consumers in src/ or tests/).
PHASE B — cacheManager dead StorageType branches
src/storage/cacheManager.ts
- Collapsed the `isRemoteStorage` flag and its 15 dead conditional branches
spanning calculateOptimalCacheSize() and calculateOptimalBatchSize().
After dropping cloud adapters in step 7, `coldStorageType` is never S3
or REMOTE_API; the branches were dead. Cache sizing and batch sizing now
honor the filesystem-only reality with simpler heuristics.
- Collapsed `detectWarmStorageType()` + `detectColdStorageType()` from
~40 LOC of environment-+-availability branching to 2-line returns of
`StorageType.FILESYSTEM`. Brainy 8.0 ships filesystem + memory only.
NOT YET — Phases C-G in follow-up commits
C: storageAutoConfig.ts + zeroConfig + extensibleConfig + sharedConfigManager
D: TODO/FIXME sweep across src/
E: skipped tests + the parallel-test race condition
F: docs deep clean (BATCHING, augmentations, READMEs)
G: browser support drop (the last 2 @deprecated)
VERIFICATION
- npx tsc --noEmit: clean
- npm test: 1408 / 1409 (same pre-existing race-condition outstanding)
Final cleanup pass for Brainy 8.0. Catches three categories of debt:
A. STEP-7 FOLLOW-THROUGH (rebuild-path collapse)
Step 7's bisect-reset (debugging a flaky test) lost the in-source edits
to three rebuild paths even though the commit message claimed they
shipped. Re-applied now:
- src/utils/metadataIndex.ts — collapsed the `isLocalStorage` /
cloud-pagination branching. Local-load-all-at-once is the only path
in 8.0. Removed ~150 LOC of paginated-cloud branching for both nouns
and verbs, plus the safety counters (`consecutiveEmptyBatches`,
`MAX_ITERATIONS`, etc.).
- src/hnsw/hnswIndex.ts — same simplification for HNSW rebuild. The
paginated cloud path is gone; HNSW now loads all nodes at once.
Removed ~85 LOC.
- src/graph/graphAdjacencyIndex.ts — same simplification for graph
adjacency rebuild. Removed ~50 LOC.
The collapse is safe because cloud adapters were deleted in step 7;
`storageType === 'OPFSStorage'` (and similar) can never match now.
B. CLOUD-ONLY DOCS DELETED
- docs/operations/cost-optimization-aws-s3.md
- docs/operations/cost-optimization-azure.md
- docs/operations/cost-optimization-cloudflare-r2.md
- docs/operations/cost-optimization-gcs.md
- docs/operations/cloud-run-filestore-guide.md
(docs/deployment/* contained no cloud-specific files that needed deletion.)
C. STORAGE-ADAPTERS GUIDE REWRITTEN FOR 8.0
docs/guides/storage-adapters.md → fresh content reflecting the 8.0
reality:
- Two adapters: FileSystemStorage + MemoryStorage. Quick-start matrix.
- Cloud backup section explains the operator-tooling pattern (gsutil /
aws s3 / rclone / azcopy) with the exact commands consumers will run.
- "Why no cloud adapters in 8.0?" section documents the four reasons
per BR-BRAINY-80-STORAGE-SIMPLIFY.
- Migration recipe for 7.x cloud-adapter consumers: mount local disk →
filesystem storage → operator backup cron.
Updated frontmatter description so soulcraft.com/docs renders the
correct preview.
NOT IN THIS COMMIT (deliberate, lower-priority)
- src/storage/cacheManager.ts still references StorageType.S3 /
REMOTE_API / OPFS as dead branches (23 sites). The branches are never
reached in 8.0, but cleaning them would cascade through 5 consumers.
Defer to a follow-up if the dead code surfaces as a real maintenance
issue.
- src/config/storageAutoConfig.ts keeps its StorageType enum + autodetect
for 7.x compat surface. Same reason: rewriting cascades through
zeroConfig, extensibleConfig, sharedConfigManager. Defer.
- docs/MIGRATION-V3-TO-V4.md and docs/DEVELOPER_LEARNING_PATH.md still
reference cloud adapters as historical artefacts. That's accurate —
they describe how things used to be. Left as-is.
- @deprecated audit in src/ (10 files) deferred — audit each individually
in a future polish pass.
VERIFICATION
- npx tsc --noEmit: clean
- npm test: 1408 / 1409 (same pre-existing race-condition outstanding from
step 7; no regressions from this cleanup)
Native accelerators (cortex) register providers for metadataIndex, graphIndex,
hnsw, entityIdMapper, cache, columnStore, and aggregation. Until now the exact
method/property surface brainy calls on each was implicit — a provider could
drop a member brainy depends on and only fail at runtime when that path ran.
This defines and exports the provider contracts from the stable
@soulcraft/brainy/plugin entrypoint:
- MetadataIndexProvider, GraphIndexProvider, HnswProvider,
EntityIdMapperProvider, CacheProvider — each typed as exactly the surface
brainy calls (optional/feature-detected members like HNSW setPersistMode and
enableCOW are intentionally excluded).
- Re-exports ColumnStoreProvider and AggregationProvider (and the aggregate
types) from the same entrypoint so a plugin author can import the whole
provider surface from one place.
Brainy's own baseline classes now `implements` these contracts
(MetadataIndexManager, GraphAdjacencyIndex, HNSWIndex, EntityIdMapper,
UnifiedCache), so the interfaces can never silently diverge from what brainy
ships — and any provider that declares `implements` gets a compile error the
moment brainy starts requiring a new member.
The embeddings/embedBatch providers stay typed by the existing EmbeddingFunction
(no duplicate interface added). Type-only changes; no runtime behavior change.
Replaces localeCompare / raw relational operators with compareCodePoints (UTF-8
byte order) in the remaining persisted or native-facing comparison sites:
- SSTable sourceId sort + zone-map range check + binary search (graph LSM)
- COW TreeObject + RefManager name sorts (reproducible content hashes and ref
listings across environments)
- getSortedIdsForFilter (numeric-aware; code-point for strings) so the JS sort
fallback matches the native column store exactly
Deterministic across OS/Node/ICU and byte-identical to the native engine. No
migration: COW serialize/deserialize preserve stored order, so existing trees
keep their hashes; only new writes adopt code-point order.
SSTable.calculateChecksum() used require('crypto') which breaks in ESM
environments and Bun. Replace with top-level import { createHash } from
'node:crypto' — SSTable is Node-only (LSM-tree filesystem storage) so
a direct node:crypto import is appropriate.
GraphAdjacencyIndex.flush() was a no-op — LSM MemTables were never
written to SSTables for datasets under the 100K auto-flush threshold.
This caused readdir, getRelations, and getDescendants to return empty
results after close + reopen.
Three fixes:
- LSMTree.get(): merge MemTable + SSTable results (data spans both
after flush, old early-return missed SSTable data)
- GraphAdjacencyIndex.flush(): actually flush all 4 LSM-trees
- GraphAdjacencyIndex.close(): close all 4 trees (was only closing 2)
Also: brain.close() and shutdown hooks now call close() on graphIndex,
HNSW index, and metadataIndex to release timers and file handles.
Shutdown/close/flush now properly flushes all 4 components in parallel:
metadataIndex, graphIndex, HNSW dirty nodes, and storage counts. Previously
only counts were flushed, causing native provider data loss on restart.
Also:
- Wire roaring, msgpack, entityIdMapper provider consumption from plugins
- Fix allOf filter O(n²) intersection → O(n) Set-based
- Fix ne/exists negation filter to use Set-based exclusion
- Add setMsgpackImplementation() swap in SSTable for native msgpack
- Add setRoaringImplementation() swap for native CRoaring bitmaps
- Add getAllIntIds() to EntityIdMapper for bitmap operations
- Remove TypeAwareHNSWIndex from default index creation path
- Export memory detection utilities from internals
- Clean up 26 permanently-skipped dead tests
The __words__ keyword index stores 50-5000 entries per entity (one per
word), which inflated avg entries/entity well above the corruption
threshold of 100. This caused:
1. validateConsistency() to falsely detect corruption on every startup,
triggering unnecessary clearAllIndexData() + rebuild() cycles
2. getStats() to log false "Metadata index may be corrupted" warnings
and report inflated totalEntries/totalIds stats
Both methods now skip __words__ when counting, so stats and health
checks reflect metadata fields only (noun, type, createdAt, etc.).
Keyword search is unaffected since the __words__ field index itself
is not modified.
BREAKING: This is a critical architectural fix for the VFS tree corruption bug
reported by Soulcraft Workshop team. The fix addresses the root cause: dual
ownership of GraphAdjacencyIndex causing verbIdSet to be out of sync.
## Root Cause Analysis
The bug was caused by TWO separate GraphAdjacencyIndex instances:
1. Storage.graphIndex (created in BaseStorage.init())
2. Brainy.graphIndex (created in Brainy.init())
When verbs were saved, both instances were updated. But if Storage's graphIndex
was recreated (via ensureInitialized()), the new instance had an empty verbIdSet.
Queries filtered through this empty verbIdSet returned nothing - making data
appear lost even though it existed in the LSM-trees.
## Fix Summary
1. **GraphAdjacencyIndex Singleton Pattern**
- Removed direct creation from BaseStorage.init()
- Brainy now uses `storage.getGraphIndex()` instead of creating its own
- getGraphIndex() has proper singleton pattern with concurrent access protection
- Added `invalidateGraphIndex()` for branch switches
2. **Auto-rebuild verbIdSet Defense**
- Added check in ensureInitialized(): if LSM-trees have data but verbIdSet
is empty, automatically populate verbIdSet from storage
- This is a safety net for edge cases
3. **Removed Double-Add Bug**
- Removed graphIndex.addVerb() from saveVerb_internal()
- Graph index updates now happen ONLY via AddToGraphIndexOperation in
Brainy.relate() transaction system
- This prevents duplicate counting in relationshipCountsByType
4. **PathResolver Cache Invalidation**
- Added invalidateAllCaches() method to PathResolver and SemanticPathResolver
- checkout() now clears VFS caches before recreating VFS for new branch
## Files Changed
- src/storage/baseStorage.ts: Removed graphIndex creation from init(), added
invalidateGraphIndex(), removed addVerb from saveVerb_internal()
- src/brainy.ts: Use storage.getGraphIndex() in init/fork/checkout
- src/graph/graphAdjacencyIndex.ts: Auto-rebuild verbIdSet in ensureInitialized()
- src/vfs/PathResolver.ts: Added invalidateAllCaches()
- src/vfs/semantic/SemanticPathResolver.ts: Added invalidateAllCaches()
## Testing
All VFS tests pass (7/7), including:
- mkdir() should not corrupt VFS index
- Delete and recreate folder cycles
- Contains relationship queries

Two critical issues fixed:
1. MetadataIndex.lazyLoadCounts() - Added counts to existing Map instead of
replacing. Each app restart caused counts to double, leading to 100x
inflation after ~100 restarts.
2. MetadataIndex.rebuild() and GraphAdjacencyIndex.rebuild() - Did not clear
count Maps before rebuilding, causing accumulation.
Changes:
- Clear totalEntitiesByType, entityCountsByTypeFixed, verbCountsByTypeFixed
at start of lazyLoadCounts()
- Clear totalEntitiesByType, entityCountsByTypeFixed, verbCountsByTypeFixed,
typeFieldAffinity in MetadataIndex.rebuild()
- Clear relationshipCountsByType in GraphAdjacencyIndex.rebuild()

CRITICAL FIX: VFS bug that persisted through v4.5.1-v4.7.4 is NOW FIXED.
Root Cause:
- Storage adapters were not properly extracting standard fields from metadata
- This caused getVerbsBySource_internal() to return 0 relationships despite relationships existing
- VFS PathResolver couldn't navigate directory structure
Solution - Metadata Architecture Refactoring:
1. Move standard fields to top-level of HNSWNounWithMetadata and HNSWVerbWithMetadata
- type, createdAt, updatedAt, confidence, weight, service, data, createdBy
2. Update all 9 storage adapters to extract standard fields from metadata on load
3. Maintain backward compatibility at storage layer (metadata files unchanged)
Changes:
- src/coreTypes.ts: Update HNSWNounWithMetadata and HNSWVerbWithMetadata interfaces
- Add top-level standard fields
- Change data type from unknown to Record<string, any>
- Add confidence field to GraphVerb
- src/storage/baseStorage.ts: Add type cast pattern for standard field extraction
- src/storage/adapters/*.ts: Fix all 9 adapters (memoryStorage, fileSystemStorage, gcsStorage,
s3CompatibleStorage, r2Storage, opfsStorage, azureBlobStorage, typeAwareStorageAdapter)
- Extract standard fields from metadata on load
- Place at top-level of returned entities
- src/api/DataAPI.ts: Read fields from top-level instead of metadata
- src/graph/graphAdjacencyIndex.ts: Convert HNSWVerbWithMetadata to GraphVerb format
- src/utils/metadataIndex.ts: Fix typo (metadata → entityOrMetadata)
- src/types/brainy.types.ts: Add createdBy field to AddParams
- src/types/graphTypes.ts: Add service field to GraphVerb
Test Results:
✅ VFS bug FIXED - vfs.readdir('/') now returns files (was returning empty array)
✅ getVerbsBySource_internal() now returns relationships correctly
✅ Build succeeds with ZERO compilation errors
✅ 95.7% of tests pass (954/997)
Breaking Changes:
- None - backward compatibility maintained at storage layer
