Pickup corrections are hiding the pattern

Maintenance found compacted plastic in one finger recess. They removed it and checked the mounting. The jaw contact looks more even now, though we haven't tried the full tray set.

Try identified trays under the approved test procedure. Don't call the first clean pickup the result.

Three trays behaved; one still presents the block at an angle. So the debris mattered, but it wasn't our entire collection of problems. That tray is set aside for inspection.

Check its pocket and seating surfaces. Two causes can produce the same ugly pickup.

We cannot. The old records say only 'tray changed'. I've added tray identity and the observed symptom to our interruption log. It won't rescue the history, but the next investigation should have less archaeology.

Measure that set-aside tray against a known good one before ordering replacements; the visible lean might come from how the block sits in the pocket rather than the tray outline.
