The scratch moved when we moved the lamp. Now what?

Found the faceplate in the sample box, labelled reject in one bag and suspect on the part tag. Nice to have our disagreement physically archived too

Retain both labels in the history, but ask for one current judgement under defined viewing conditions before using that piece as a definite reject reference.

And the moving bright line doesn't prove the faceplate is flawless; don't turn a bad reject label into an equally casual pass.

Agreed; uncertainty is an appropriate outcome until the physical inspection question is settled.

That comparison can inform the imaging work, provided the sample identity and physical judgement remain attached to it rather than inferred from the bright line alone.

Same area, yes. The line crosses a small tooling feature between images. Quality is looking at the actual part with agreed viewing conditions. I haven't called it good, just stopped calling the photo proof of a scratch

We had a reference folder where uncertain parts quietly became rejects after a handover. Giving uncertain samples their own status helped. Include who resolves them, or they can sit there until somebody gets impatient and relabels the lot.

Quality owns the suspect list now. They've supplied a small set of agreed good and bad parts for the lighting comparison. This faceplate stays suspect, so no victory lap for the lamp yet

Use those agreed samples when documenting the operator inspection view too, so the eventual handover explains the acceptance standard rather than merely where to look for a bright pixel.
