Replace the abandoned llms-txt-mcp/Chroma docs backend with an in-repo MCP service: SQLite WAL + FTS5 + sentence-transformer embeddings, transactional source replacement, persisted state across restarts, singleflight refresh with conditional requests, hybrid lexical/semantic ranking with exact-duplicate collapse, source/host filters, and explicit-by-default content retrieval. Add docs_rebuild and a docs-rebuild CLI command. Add deterministic llms-full.txt snapshot generation for machine-local menus with hash-validated provenance manifests; lifecycle commands promote a local menu to its snapshot only when the manifest validates. Switch public source profiles to content-bearing llms-full.txt feeds. Improve web search: bounded provider fallback with per-attempt diagnostics and cancellation, an optional Brave Search API provider, strict SearXNG engine selection, capped link/media extraction, and a real engine=browser renderer that routes every request through the existing SSRF vetting while blocking WebSockets, non-GET traffic, and private destinations. Extend release checks with offline unit suites and isolated candidate container tests for both images.
