our bracket notes compare a clamped reading with a released one

I am checking the old gusset-bracket notes for our FR5 proposal and the claimed movement compares a fixture tick with a released measurement, but nobody wrote down what the tick actually checked.

Find the person or instruction behind the tick before treating it as a dimension. It may mean the assembly was against its intended contacts, not that somebody measured the feature later found outside tolerance.

Setter says the tick meant the parts were seated before welding, with no measurement of the final feature, so our spreadsheet has been calling two different checks a before-and-after pair.

Remove that calculated movement. Keep the seating observation and the released result as separate facts, then define what a genuinely linked comparison must measure.

Calculated movement removed, and the new study sheet separates incoming fit-up, seating, first released measurement, correction and final acceptance, with each stage tied to the same bracket.

Who enters the correction stage when fabrication does it? Inspection cannot reconstruct the work merely because the bracket eventually passes.
