verify-acceptance-criteria

Checks implementation evidence (code, PR, screenshots, API responses, or a running app) against acceptance criteria and marks each criterion Met, Partial, Not Met, or Untestable, with cited evidence and a sign-off summary. Use when a story is ready for review or sign-off, or when someone asks whether a feature does what was agreed. To review the criteria themselves before implementation, use the review-requirements command; to map requirements to existing tests, use the map-requirements-coverage command.
