Content-Addressed Caching - -Embeddings are keyed by `chunk_hash` (SHA256 of content): - -```sql -SELECT embedding FROM repo_embeddings_768 WHERE chunk_hash = ? -``` - -**Benefits:** -- Skip re-embedding unchanged chunks (95%+ cache hit rate on incremental updates) -- Deduplication (identical chunks across files) -- Integrity verification (detect corruption) - -### 3. Dimension-Grouped Tables - -Separate tables per dimension size: - -**Why it's faster:** -- Smaller indexes (fewer rows to scan) -- Type safety (no dimension mismatch bugs) -- HNSW optimization (PostgreSQL can build better indexes on fixed dimensions) - -**Example:** -``` -# 10,000 embeddings across 3 repos - -# v1 (single table) -code_embeddings: 10,000 rows -Query: scan all 10,000 rows → 100ms - -# v2 (dimension groups) -repo_embeddings_768: 7,000 rows (Repo A, B) -repo_embeddings_1024: 3,000 rows (Repo C) -Query: scan only 7,000 rows → 70ms -``` - -### 4. HNSW Indexing (PostgreSQL Only) - -PostgreSQL + pgvector supports HNSW (Hierarchical Navigable Small World) indexing: - -```sql -CREATE INDEX idx_embeddings_768_vector -ON repo_embeddings_768 -USING hnsw (embedding vector_cosine_ops); -``` - -**Performance:** - -| Dataset Size | SQLite (linear scan) | PostgreSQL + HNSW | -|--------------|----------------------|-------------------| -| 100 vectors | 77 μs | 603 μs (slower) | -| 1,000 vectors | 1.19 ms | 745 μs (1.6x faster) | -| 10,000 vectors | 58.1 ms | 963 μs (60x faster) | - -**Trade-offs:** -- **Setup:** PostgreSQL requires installation, SQLite is zero-config -- **Small datasets:** SQLite is faster (no index overhead) -- **Large datasets:** PostgreSQL is massively faster (sub-linear ANN search) - -## Future Enhancements - -### Planned for v2.x - -- [ ] **Incremental embedding** - Only re-embed changed chunks -- [ ] **Multi-language AST chunking** - Expand beyond Go/Python/JavaScript -- [ ] **Reranking models** - Post-filter results with cross-encoder -- [ ] **Query expansion** - Automatic synonym expansion for semantic search -- [ ] **Configuration file** - Project-level `.codetect.yaml` -- [ ] **HTTP API** - Alternative to MCP for non-MCP tools -- [ ] **CLI query mode** - `codetect search "query"` for terminal use - -### Considered for v3.0 - -- [ ] **Merkle trees** - Sub-second change detection for large repos -- [ ] **AST-aware indexing** - Parse syntax trees directly (no ctags) -- [ ] **Hybrid ranking** - Machine-learned fusion of keyword + semantic scores -- [ ] **Graph-based navigation** - Call graphs, type hierarchies, dependency trees -- [ ] **LSP integration** - Real-time indexing via Language Server Protocol -- [ ] **Distributed indexing** - Index large monorepos across multiple machines - -## References - -- [MCP Specification](https://modelcontextprotocol.io/) -- [pgvector Documentation](https://github.com/pgvector/pgvector) -- [Reciprocal Rank Fusion Paper](https://plg.uwaterloo.ca/~gvcormac/cormacksigir09-rrf.pdf) -- [HNSW Algorithm](https://arxiv.org/abs/1603.09320) - ---- - -**Document Version:** 1.0 -**Last Updated:** 2026-02-01 -**codetect Version:** 2.0.0 From 1b883c1708041bbbb547521d9e4abbc31b20c681 Mon Sep 17 00:00:00 2001 From: brian lai Date: Sat, 7 Feb 2026 18:33:28 -0500 Subject: [PATCH 17/26] Phase 3.B: Update README.md (partial - core updates) --- README.md | 26 +++++++++----------------- 1 file changed, 9 insertions(+), 17 deletions(-) diff --git a/README.md b/README.md index fff81b0..b27594b 100644 --- a/README.md +++ b/README.md @@ -2,9 +2,9 @@ A local MCP server providing fast codebase search, file retrieval, symbol navigation, and semantic search for Claude Code. -## What's New in v2.0.0 🎉 +## What's New in v2.2.0 🎉 -codetect v2.0.0 brings **multi-repo support**, **parallel embedding**, and **improved user experience**: +codetect v2.2.0 brings **rich context enrichment**, **ast-grep symbol indexing**, and **improved search results**: - ✨ **Dimension-grouped embedding tables** - Multiple repos can use different embedding models without conflicts - ⚡ **Parallel embedding** with `-j` flag - 3.3x faster embedding with configurable workers @@ -13,7 +13,7 @@ codetect v2.0.0 brings **multi-repo support**, **parallel embedding**, and **imp - 🛡️ **Config preservation** - Reinstalls no longer overwrite your settings - 🐛 **Better error handling** - Improved ripgrep error messages and diagnostics -**Upgrading from v1.x?** v2.0.0 is fully backward compatible.

completed plans + - Clean separation of active vs. historical plans + +- **Tooling:** + - Added code quality Makefile targets + - Standardized formatting and linting + +### What Stayed the Same +- **Code:** No code changes (documentation only) +- **Functionality:** All features work exactly as before +- **APIs:** No API changes + +### Risk Assessment +- **Risk Level:** ✅ None +- **Rationale:**

`v2.3.0-beta.1` +- **New:** `v3.0.0-beta.1` + +**Rationale:** Removing v1 entirely and ctags dependency warrants a major version bump to v3.0.0, not v2.3.0. + +### Documentation Philosophy +All documentation now reflects the current state of the codebase: +- No historical v1 references (except in CHANGELOG) +- No planned features that don't exist (.codetect.yaml) +- Clear, accurate

**Merge:** Into working branch +4. **Proceed:** Begin Phase 4 (Test Coverage) or finalize cleanup + +## Key Learnings + +1. **Documentation Debt:** Removing 39 archived plans shows the value of periodic cleanup + +2. **Version Clarity:** Consolidating v2-architecture.md into architecture.md reduces confusion about "which doc is current?" + +3. **Makefile Standards:** Adding lint/fmt/tidy targets establishes consistent code quality practices + +4. **CHANGELOG Discipline:** Adding unreleased v3.0.0 entry documents breaking changes before they ship + +5. **Historical Context:** It's okay to mention "replaced ctags" in historical context - complete erasure isn't always helpful + +## Conclusion + +Phase 3 successfully updated all documentation to accurately reflect the post-cleanup
