ruflo 3.68.0: agents remember past sessions

Plain-language write-up: https://gist.github.com/ruvnet/7a0f4626da9e22a5bc39fca62dc0e37a

When a session ends with a summary, ruflo now saves it as an agentdb episode, and agents can search those episodes later. The search runs on agentdb 3.2.0 and blends meaning search with keyword search. A paraphrase finds the right session, and so does an exact ticket id or function name. An optional local reranker improves the ordering further.

Added

• agentdb_episode-recall MCP tool. It searches past sessions and memory distill episodes. rerank: true costs about 0.1–0.2 s and downloads a 23 MB model on first use.
• agentdb_session-start accepts recall: true and returns related past episodes.

Fixed

• Session episodes are stored. The bridge called startEpisode/endEpisode, which agentdb has never had, so nothing was ever saved. Episodes are now stored as neutral (reward 0), because the outcome is unverified.

Changed

• agentdb ^3.2.0, which brings in ruvector 0.3.5.

Measured

• LongMemEval_M, top-5 recall_all (agentdb ADR-016): vector only 0.630 → hybrid 0.719 → with rerank 0.789. The paper's best is 0.762.
• Fresh npm i ruflo@3.68.0, MCP stdio:
• recall in 13–31 ms;
• with rerank, 96 ms once the model is cached;
• stdout is JSON-only;
• one agentdb copy in the tree;
• npm audit: 0 critical.
