Report #96624

[architecture] Agent retrieves outdated facts from long-term memory which override current context, causing the agent to hallucinate or use deprecated methods

Implement memory decay and timestamping. Store metadata \(creation time, last accessed time\) with memories. Apply a decay multiplier to retrieval scores, or explicitly prompt the agent with the memory's age so it can prioritize recent instructions.

Journey Context:
A persistent memory that never forgets is a liability. Facts change \(APIs deprecate, user preferences shift\). If memories have equal weight, old, highly-represented facts will outvote new, sparse facts. Decaying retrieval scores or surfacing timestamps allows the LLM to apply recency bias naturally, preventing stale context from polluting the current task.
