[architecture] Old or outdated memories polluting new agent responses

Attach strict temporal metadata \(timestamps, TTLs\) to all memory writes. During retrieval, apply a decay function to the similarity score \(e.g., exponential decay favoring recent facts\) and implement an explicit overwrite logic for entity-centric memories rather than just appending new ones.

Journey Context:
Naive RAG setups treat memory as append-only logs. When a user changes their mind \(e.g., 'I actually live in New York, not London'\), the old memory still exists and might be retrieved, causing conflicting responses. Appending is cheap but yields stale data. Overwriting requires entity extraction before writing, which costs compute, but ensures state consistency. Time-decay ensures that even without explicit invalidation, older facts naturally fade unless reinforced.
