  "assessmentWarning": "The accepted field records whether the historical agent-assisted screen marked an output usable. It is not a measured strict-acceptance result. Original notes and contradictory judgments are preserved.",
  "acceptanceCriteria": "Camera must move left-to-right; the cube itself must remain stationary and retain its marked-face orientation. Foreground markers must shift more than background markers in a direction consistent with the requested arc. Critical failures specified before generation: The cube rotates, deforms, changes color or loses its white face marker. Camera direction is wrong, parallax is absent or zoom substitutes for the arc. The clip cuts, becomes severely unstable or crops the cube.",
  "acceptanceProvenance": "The task pack records the original brief before the run. No strict acceptance measurement is available for these videos. The JSON accepted field preserves only the historical agent-assisted usability assessment: true means marked usable; false means marked not usable. The assessment did not establish strict compliance with every stated condition. Read each original note and inspect the video. No scores were changed for this integration.",
