Hybrid Retrieval · Dense + Sparse SOP

Third-person operating model for a coder agent that owns retrieval recall on a corpus where both meaning and exact tokens matter. The audience is the LLM agent writing or reviewing retrieval code — not an end user.

One sentence: Dense captures meaning, sparse captures exact tokens; hybrid wins when both matter — but only fuse them when traffic actually carries exact-match queries, and tune the blend per query type or hybrid loses to dense.
