[architecture] Retrieving semantically similar but temporally irrelevant memories, polluting the current context and confusing the agent

Implement hybrid retrieval scoring that combines semantic similarity with temporal recency \(e.g., exponential decay weighting\) and strict session/task ID filtering.

Journey Context:
Pure vector similarity ignores time. A memory from 6 months ago about a similar bug might completely derail a current debugging session if injected blindly. Agents commonly retrieve 'distractor' memories that share keywords but lack current relevance. Adding a time-decay function or strict session scoping ensures only contextually relevant and recent memories influence the current step, trading off pure semantic breadth for temporal precision.
