old bracket sheets disagree about when 'pass' was measured

I'm reviewing records for our UR5e welding proposal. 'Pass' sometimes means clamped, sometimes released. Poor inheritance.

Separate those measurement conditions before drawing a trend. A clamped alignment check and final inspection may answer different questions, even if both were labelled pass.

Some sheets say neither. The old correction note just says 'pull into fixture'.

That note is not a transferable process definition. Identify what is unknown rather than asking a new operator to reproduce an undocumented correction by feel.

Photograph the current fixture and identify its revision in the review. The old sheets may describe different stops or supports. And keep final acceptance tied to the drawing's specified inspection conditions.

Include incoming fit-up observations where they exist. Otherwise all variation enters the discussion at the fixture, simply because that is where the old records begin.

I've marked unknown conditions explicitly. No correction routine goes forward from these sheets alone.
