[architecture] Agent accumulates irrelevant facts over time, degrading retrieval precision and wasting token space

Implement memory decay using a time-weighted access counter \(e.g., exponential decay on metadata\) to demote or archive rarely accessed memories, and periodically purge zeroed-out records.

Journey Context:
A memory system that only appends will eventually suffer from semantic crowding, where the vector space becomes so dense that any query returns a mix of relevant and irrelevant facts. Human memory naturally forgets; agent memory must artificially forget. Using an access counter ensures frequently used facts \(like a user's name\) stay prominent, while one-off instructions fade, maintaining high retrieval precision over long lifetimes.
