Agent Memory Lifecycle: Corrections, Retention, and Deletion

Agent memory should be managed through a clear lifecycle that distinguishes temporary context selection, factual corrections, retrieval exclusion, and permanent deletion, since these actions may produce similar immediate answers while retaining different underlying data. Systems should define user requests precisely, such as whether a preference should no longer be used, should be updated, or should have its stored source removed, and should verify effects across profiles, search, documents, caches, conversation histories, and synchronization processes. In Supermemory, forgetting a memory is a soft deletion that excludes it from default search but retains the entry, while imported source documents require separate deletion operations. Corrections should preserve relevant historical context when appropriate without overriding current authoritative data, and temporary instructions should not unintentionally replace lasting preferences. Applications should map all potential paths through which removed information could return, enforce tenant-level authorization for lifecycle actions, establish retention policies based on record purpose and validity, and test observable end-to-end outcomes using controlled scenarios, including resynchronization and cross-user access checks.
