Report #44610

[architecture] Old, irrelevant memories retrieved via semantic search override current task context

Apply recency weighting and decay functions to memory retrieval scores, and explicitly prompt the agent to evaluate if a retrieved memory is relevant to the current state before acting on it.

Journey Context:
Pure semantic search retrieves based on meaning, ignoring time. A memory from 10 sessions ago about 'using Python 3.8' might semantically match 'using Python' today, but the project upgraded to 3.11. If the agent blindly trusts high-similarity scores, it uses stale dependencies. Strict TTL deletes everything, losing long-term preferences. The right call is a hybrid score: semantic\_similarity \* recency\_decay, plus an explicit relevance check step.
