Report #39410

[frontier] Agent conflates specific historical failures \(episodic\) with general rules \(semantic\), creating overly restrictive or permissive behavior after many turns \(episodic leakage\)

Strictly separate vector stores: one for 'lessons learned' \(semantic, generalized\) updated only through structured reflection, and one for 'incident logs' \(episodic, read-only\), with explicit architectural gates preventing raw logs from directly updating behavioral rules

Journey Context:
Advanced agents use RAG to inject past context; naive implementations store conversation turns as 'memory'; however, this creates 'episodic leakage' - when the agent retrieves 'I failed to do X on March 1st', it treats this as a permanent constraint \('never do X'\) rather than a specific incident; conversely, it may generalize a specific permission into universal permission; the error is architectural: most vector stores don't distinguish between episodic \(time-bound, specific\) and semantic \(timeless, general\) memory; frontier teams \(2025\) implement dual-store architectures with a 'reflection layer' - raw episodic memories go to an append-only log, and a separate process \(not the live agent\) distills these into semantic rules using structured reflection prompts; the live agent only queries the semantic store for behavioral rules and the episodic store only for specific historical facts, never letting raw history directly influence behavior without generalization; this prevents specific failures from creating permanent over-restrictions
