Card Front and Back Sheet Correspondence

Check front/back card-face pairing after an explicit sheet-axis flip and optional180degree back rotation.

Check front/back card-face pairing after an explicit sheet-axis flip and optional180degree back rotation. Inputs use zero-based row/column cells, at most 128faces per side and 32by32sheet dimensions. This tests correspondence only; printer feed conventions, face artwork orientation and trim registration require separate review. Calculations use supplied measurements and owner-defined tolerances only. No physical inspection, accessibility certification, clinical interpretation, structural approval or external system change is included. Use consistent units. Tolerance comparisons use the same twelve significant digits as the report. Integral report quantities must remain exactly representable; unsupported calculation profiles reject before checkout. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
