Report #57218

[architecture] Agent retrieves irrelevant but recent memories instead of highly relevant older ones

Combine semantic similarity with recency weighting using a decay function on timestamps during retrieval scoring.

Journey Context:
Pure vector similarity ignores time. A query about 'project requirements' might pull an old cancelled project's requirements instead of the current one. Pure recency ignores long-term relevant facts. The solution is a hybrid score: Score = alpha \* similarity \+ \(1-alpha\) \* recency\_decay. The tradeoff is tuning the alpha parameter for the specific use case.
