Report #94584

[architecture] Old but semantically similar memories polluting the current context window and confusing the agent

Use a composite retrieval score combining semantic similarity, recency \(exponential decay\), and importance, rather than pure vector similarity.

Journey Context:
Pure vector similarity retrieves irrelevant old data just because it matches the query keywords. A memory from 2 years ago about 'canceling a subscription' shouldn't override a memory from yesterday. Exponential time decay ensures recent context takes precedence, while importance weighting ensures critical events aren't forgotten immediately.
