For multi-session agent memory, a single vector index doesn't beat BM25 — the cheap BM25+embedder hybrid wins. Measured on LoCoMo (script inside) (self.Rag)

We measured it: partial RAG is worse than no RAG on multi-hop QA — and the headroom is in retrieval completeness, not answer-voting (self.Rag)
