}Use when a generated video missed its brief, keeps repeating a defect, or the user asks whether to rerender. Compare an existing fal result URL or a local intake clip with the brief and previous attempts. Returns timestamped evidence and whether to edit, try one targeted change, switch approach, or pause for review. Uses host vision when supported.
