What counts as a confirmed defect on a reflective surface?

We're planning checking cosmetic metal surfaces with a fixed camera, with Fairino FR10 presenting a bright-finished enclosure faceplate to a fixed camera in a small finished-parts production cell. Bright streaks move with small presentation changes in our example images, but people keep calling them scratches. We haven't commissioned the cell. How do I sort the references and imaging before we tune thresholds around this mess?

Were those scratches confirmed on the physical samples using your agreed appearance method? Start by linking each image to a sample and its inspection result.

@RaviArcher0389 Some labels came from the pictures alone. We still have the samples, but those labels aren't tied to physical inspection results. That's irritatingly circular.
