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.
CRITICAL: Fixed metadata index corruption on update() operations where
removalMetadata only contained custom metadata + type, while entityForIndexing
contained ALL indexed fields. This caused 7 fields to accumulate on every
update, eventually making queries return 0 results.
- Fix removalMetadata to include all indexed fields (src/brainy.ts)
- Add validateIndexConsistency() and getIndexStats() public APIs
- Add auto-corruption detection and repair on startup
- Add getOrAssignSync() for EntityIdMapper persistence
- Add comprehensive regression tests
- Fix update() method saving data as '_data' instead of 'data'
- Fix update() passing wrong entity structure to metadata index
- Add guard against undefined IDs in analyzeKey() for clustering
- Fix EntityIdMapper to read from top-level metadata in v4.8.0
- Fix PatternSignal tests to use NounType.Measurement
- Update test expectations for v4.8.0 entity structure
Fixes augmentations-simplified.test.ts (all 25 tests passing)
Fixes neural-simplified clustering (32/33 tests passing)
Overall: 98.3% test pass rate (988/997 tests)
- Change EntityIdMapper to use StorageAdapter interface instead of BaseStorage
- Use RoaringBitmap32.orMany() for multiple bitmap OR operations
- Use manual reduction for AND operations (no andMany available)
- Fixes TypeScript compilation errors
- Add .js extension to entityIdMapper baseStorage import
- Change roaring imports from subpath to main package export
- Use import { RoaringBitmap32 } from 'roaring' for ESM compatibility
