}Propose Memory Store changes
Freeze a MemoryProposal from 1–200 put/delete operations against the store’s current canonical base. The server normalizes paths, derives the MemoryActor from authentication, and freezes base revision, head revision, and diff hash at creation. This is the only way shared canonical memory — workspace-, agent-definition-, and surface-owned stores — advances. Send Idempotency-Key; the proposal returns open, awaiting a decision.
Checkfu support posture: preview; rollout_fenced. Required evidence journey: memory-stores. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
