verify
You MUST use this when anyone - you, a subagent, or the user - is about to state that work is done, fixed, ready, or mergeable, and before a merge, opening a pull request, or a handoff report, including work that has no plan. Covers every promise behind the claim - spec criteria, plan tasks, record entries, accepted review fixes, and the caller's words - proven with fresh checks on the committed tree and given one verdict, without editing code. Not for fixing failures (implement) or reviewing (cr-request). Replaces devflow verification-gate.
