Retained covers are numbered; moving bright bands still carry unverified scratch captions. Which physical decisions should lead the controlled imaging comparison?
Has quality identified the required appearance decision for each retained region, including an accepted finish example? Numbering the covers gives traceability, but it does not yet say what the camera must distinguish.
Then keep those captions out of the reference answers. They can explain the imaging problem without deciding that the underlying cover is accepted or rejected.
I'd keep full views with the numbered parts too. I can follow an arrow on a cropped shiny corner quite confidently and still be looking at the wrong corner; the link needs to survive somebody who wasn't there when it was drawn.
Now compare those same covers under recorded seating, presentation and lighting conditions. Change the factors separately enough to know whether a disappearing score follows the illumination or the part's actual position.
That gives the view revision a real job to do. Please keep the accepted cover in the next comparison as well; it would be a shame to recover the score by teaching the camera to dislike every bright region.
