I paused bezel thresholds until the physical review; these FR10 trim-plate examples need the same discipline. Bright streaks move with presentation but get called scratches. What capture comparison should follow the physical judgement before commissioning?
Repeat the same identified plates over the intended presentation range, recording holder and lighting conditions and required surface coverage. Keep physical judgement fixed while assessing what each image makes visible.
Thanks Rachel. Quality has the retained plates, and the capture sheet now separates their judgement from visibility. Two old photos lack reliable setup details, so they won't stand in for repeatability evidence
