Memory Decay & Forgetting Policies(MDF)
Explicit governance of what an agent drops rather than what it keeps: time-based expiry (TTL), usage and relevance decay (Ebbinghaus-style exponential decay that is boosted each time an item is accessed), staleness detection for facts that are still relevant but no longer true, and hard deletion for right-to-be-forgotten and GDPR Article 17 compliance. Unbounded memory measurably degrades agent performance, so forgetting is a first-class design axis. Distinct from `memory-consolidation` (which compresses and abstracts memories into schemas, the opposite operation) and from `generative-agents-memory` (which uses recency decay only as a retrieval score, not as an eviction or deletion policy).
