Report #77480

[architecture] Agent accumulates stale facts leading to contradictory or outdated responses over long sessions

Implement a composite retrieval score combining semantic similarity, recency \(exponential time decay\), and importance. Periodically run a curation step to archive or delete low-access, high-age memories.

Journey Context:
Infinite accumulation sounds ideal but leads to context pollution and vector store bloat. Human memory naturally decays. Without decay, an agent might use a deprecated API key or old user preference. Recency bias must be tuned so the agent doesn't forget the current task, but also doesn't cling to the distant past. Pure semantic similarity ignores the temporal dimension entirely.
