THE DEFECT (Verdict-6 dominant visual class, 5+ ROMs): the 48px/6-digit score kernel sets NUSIZx=3-copies-close and rewrites GRPx between copies so each 8px copy shows a different digit. Our renderer drew each line from ONE end-of-line snapshot state — all three copies rendered the same bytes ("three sets of scores that are just one").
Raw traces, ROM material, local paths, and personal data are not part of this public record.
