Source-local detail only. Bill reading retained separately from A-A candidate; no choice of installed fastener. Review correction review-correction-20261013j-closure1011aa-img991-bill-screw-diameter: The enlarged crop of the same IMG_0991 bill row reads 3/8 in, not 7/8 in. Numerator 3 is distinct; the unchanged 620-piece CSK row and 2 in length establish the same scope.
