Report #46758

[architecture] Agent retrieving outdated or irrelevant past solutions that override current task context

Implement a time-decay weighting factor in your vector search scoring \(e.g., exponential decay based on timestamp\) and an explicit invalidation operation when a memory is contradicted by new information.

Journey Context:
Vector databases return results based on semantic similarity, meaning a 6-month-old bug fix might score higher than a recent, subtle change because the older text is a closer lexical match. This causes the agent to revert code to old states. Adding a recency bias ensures newer memories win ties. Furthermore, when a user corrects the agent, the agent must execute a hard delete or invalidation of the conflicting old memory, not just append the new one. Appending causes the DB to argue with itself.
