From 951e514fd7434ab489f750557304d1d8bd76e046 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Wed, 15 Oct 2025 12:26:25 -0700 Subject: [PATCH] feat(types): Phase 0 - Type System Foundation for billion-scale optimization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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: -
