Milestone: Knowledge Engine (March 1, 2026)
Knowledge Engine (Act 2) — March 1, 2026
What shipped
- Block parser — HTML content decomposed into typed blocks (heading, paragraph, list, table, code, mermaid) with anchor_ids for direct section access
- Compiled pages — cached rendered HTML for fast retrieval
- Semantic search — pgvector + Ollama (qwen3-embedding:4b), 6,054 blocks embedded
- MCP server v0.3.0 — expanded to 33 tools including block-level operations and semantic search
Significance
The system went from "notes in a database" to "knowledge engine." Block decomposition enabled 91% token reduction via block-first access. Semantic search enabled meaning-based queries across all content. The foundation for every future capability.
