Question
Using the resolved remote-contract, local-store, and user-contract tickets, produce a concise non-code implementation specification and executable follow-on issue breakdown that names the initial entities, sync/checkpoint behavior, source-of-truth rule, schema/migration approach, command/output contract, safeguards, and verification matrix; identify any remaining assumptions instead of deciding them by implication.
