Keep an agent's saved memories and session handoff notes true — verify each against the repository, merge duplicates, retire finished handoffs, fix the memory index, and route drifted docs to an audit. Use when a startup check or a user flags stale memories, at a checkpoint after a batch of work, when a handoff's work is finished, or when a memory turns out to be wrong. Not for saving a new memory, not for writing or auditing project documentation (project-docs), and not for instruction files such as AGENTS.md (agent-instructions).
