I Gave My AI Agents a Memory With SQLite FTS5 (No Vector DB)

Most agent-memory setups reach for Pinecone or pgvector by reflex. I put 2000+ markdown files behind SQLite FTS5 with BM25 ranking, and my agents now answer their own 'who is X' questions in under a second for zero tokens. Here is the schema, the query, and the one place lexical search loses.
