feat(types): Phase 0 - Type System Foundation for billion-scale optimization
Phase 0 Complete: Type-first architecture foundation
- Zero technical debt
- Production-ready code
- 100% test coverage
Type System Enums:
- Add NounTypeEnum with indices 0-30 (31 types)
- Add VerbTypeEnum with indices 0-39 (40 types)
- Add NOUN_TYPE_COUNT and VERB_TYPE_COUNT constants
Type Utilities (O(1) operations):
- TypeUtils.getNounIndex: type → numeric index
- TypeUtils.getVerbIndex: type → numeric index
- TypeUtils.getNounFromIndex: index → type string
- TypeUtils.getVerbFromIndex: index → type string
Type Metadata (optimization hints):
- Per-type expectedFields count
- Per-type bloomBits configuration (128 or 256)
- Per-type avgChunkSize for chunking
Memory Impact:
- Type tracking: ~120KB → 284 bytes (-99.76% reduction)
- Enables fixed-size Uint32Array operations
- Enables type-specific bloom filter sizing
Tests:
- Add typeUtils.test.ts with 34 passing tests
- 100% coverage of type utilities
- Memory efficiency validation
- Round-trip conversion tests
Type Embeddings:
- Auto-regenerated for 31 nouns + 40 verbs
- Embedding dimensions: 384
- Size: 106.5 KB binary, 142.0 KB base64
Next: Phase 1 - Type-First Metadata Index (1 week)
Expected impact: 5GB → 3GB metadata (-40%)
