What should an AI rough cut hand back to the editor?

I’m working on CutNow, an editing tool for creators who already have the source footage. We’re testing a simple handoff: make an editable first cut from hour-long material, then open it in Jianying Pro to adjust shots, narration and captions.

The test I care about is what happens when a reviewer wants two seconds back. Can the next editor find the source shot, extend it, check the next voice-over line and re-export only what they changed? If you regularly cut recaps or narrative clips, what would you want preserved in that handoff before you trusted an automated first cut?
