[architecture] Retrieved memories are polluting current context and degrading response quality

Implement a relevance threshold and a recency-weighted scoring mechanism. Before injecting retrieved memories into the prompt, perform a secondary cross-encoder rerank or LLM-as-a-judge call to filter out semantically similar but contextually irrelevant memories.

Journey Context:
Naive RAG stuffs the top-K vector results into the context. But for agents, old memories that share keywords with the current task \(but are actually unrelated\) severely distract the LLM, causing hallucinations or abandoned tasks. Vector similarity alone is insufficient because it lacks temporal and task-boundary awareness. Reranking or filtering before injection is computationally cheaper than recovering from a confused agent mid-task.
