Brainy 8.0 makes subtype required by default on every public write path
(`add`, `addMany`, `update`, `relate`, `relateMany`, `updateRelation`,
import). Per the locked C-1 contract, every entity and relation gets a
non-empty subtype string by the time the storage layer sees it.
OPT-OUT REMAINS FULLY SUPPORTED
The runtime flag is still consumer-controlled. Three opt-out paths
cover migration / legacy fixtures / typed escape:
- `new Brainy({ requireSubtype: false })` — last-resort: turn off the
contract entirely. Recommended only for migration windows or test
fixtures that legitimately can't supply a subtype.
- `new Brainy({ requireSubtype: { except: [NounType.Thing, ...] } })` —
per-type allowlist: strict everywhere except the listed types.
- `brain.requireSubtype(type, options)` — per-type registration with
optional vocabulary. Composes with the brain-wide flag.
Default is now `true`. Opt-out is explicit and documented; nothing
silently degrades.
TEST SWEEP
Bulk-applied `requireSubtype: false` to every `new Brainy({...})` call
site across 120 test files. Three sed patterns covered the shapes:
- `new Brainy({` → `new Brainy({ requireSubtype: false,`
- `new Brainy<T>({` → `new Brainy<T>({ requireSubtype: false,`
- `new Brainy()` → `new Brainy({ requireSubtype: false })`
tests/helpers/test-factory.ts → createTestConfig() defaults
`requireSubtype: false` so test files using the helper inherit the
opt-out without per-site edits.
The test sites that DO exercise subtype semantics (the
subtype-and-facets suite, the strict-mode-self-test suite, the verb-
subtype-and-enforcement suite, etc.) already pass real subtypes — they
were the 7.30.x acceptance tests for this contract. Those tests
continue to pass unchanged.
CHANGES
src/brainy.ts
- normalizeConfig() — `requireSubtype` default `false` → `true`.
Comment refreshed to document the three opt-out paths.
tests/* (120 files)
- Bulk-edited brain construction sites. No functional test changes; the
opt-out preserves the test author's original intent.
tests/helpers/test-factory.ts
- createTestConfig() base config gains `requireSubtype: false`.
NO-OP for consumers who were already passing subtype on every write.
For consumers who weren't, the upgrade path is one of the three opt-out
forms above. Migration recipe documented in 8.0 release notes (next
commit).
VERIFICATION
- npx tsc --noEmit: clean
- npm test: 1408 / 1409 (same pre-existing race-condition outstanding;
no other regressions from the flip)
Fixed critical bug where entity and relationship counts were not being tracked correctly
during add(), relate(), and import() operations. The root cause was a race condition where
count increment code tried to read metadata before it was saved to storage.
Core Fixes:
- Modified baseStorage.saveNounMetadata_internal to increment counts AFTER metadata is saved
- Modified baseStorage.saveVerbMetadata_internal to increment verb counts AFTER metadata is saved
- Added verb type to VerbMetadata to avoid circular dependency during count tracking
- Refactored verb count methods to prevent mutex deadlocks (synchronous base + async Safe wrapper)
Storage Adapter Cleanup:
- Removed broken count increment code from FileSystemStorage, GcsStorage, R2Storage, AzureBlobStorage
- Updated MemoryStorage comments to reflect centralized fix
- All count tracking now centralized in baseStorage (fixes ALL adapters automatically)
New Utilities:
- Added rebuildCounts utility to repair corrupted counts.json from actual storage data
- Added comprehensive integration tests for count synchronization across all operations
Verification:
- All 8 storage adapters verified (FileSystem, GCS, Memory, S3Compatible, R2, Azure, OPFS, TypeAware)
- All code paths verified (add, relate, import, batch, update, delete)
- 599 tests passing (no regressions)
- No deadlocks (tests complete in 6s vs 150s+)
