The question of what knowledge deserves to remain alive is the right framing, because useful memory also needs a deliberate forgetting policy. Persisting and reusing state without provenance, freshness, and invalidation rules turns memory into an amplifier for stale decisions. For agents, I treat write, update, and delete policies as part of the memory architecture, not only the retrieval path.
