David Snelling	00d14cfa93	feat: hook native SQ8 distance provider into HNSW reranking ... Makes distanceSQ8 swappable via setSQ8DistanceImplementation and wires brainy.ts to install a registered 'distance:sq8' provider (e.g. cortex's Rust SIMD), with the JS distanceSQ8Js as the default fallback. The provider signature is byte-compatible with the native cosineDistanceSq8, so HNSW SQ8 reranking transparently uses native distance when cortex is loaded. Native==JS numeric equivalence is asserted by the cross-language parity suite.	2026-05-27 12:43:29 -07:00
David Snelling	0f3a88429d	feat: add SQ8 vector quantization, lazy loading, and two-phase rerank to HNSW ... - SQ8 scalar quantization (8-bit) for 4x vector storage reduction - Lazy vector loading: evict float32 vectors after graph construction, load on-demand from storage via UnifiedCache - Two-phase search: over-retrieve with SQ8 approximate distances, rerank top candidates with exact float32 distances - Configuration surface: hnsw.quantization and hnsw.vectorStorage in BrainyConfig - All features disabled by default (zero behavior change for existing users) - 27 new tests covering quantization accuracy, lazy loading, reranking - Remove GitHub Actions CI (build locally, cortex CI handles native builds)	2026-01-31 12:41:53 -08:00
