The solution is a write gate that filters what gets persisted based on four criteria: durability across sessions, source verification, future utility, and auditable metadata. Beyond write gates, staleness must be handled through recency-based decay in retrieval scoring, conflict detection at write time, and explicit supersession (marking old memories inactive rather than deleting them). Long-lived agents also need deliberate forgetting semantics for privacy, consent revocation, and quality — memory hygiene is a production requirement, not an optional optimization. ## Full article daily.dev links to this article rather than hosting it.
