Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.

EL.190.53190.53 ft
Fan room only; last-decimal reading merits confirmation against Sh.224. Review correction review-correction-20261014b-f8-room-fan-floor-elevation: Native same-witness crop reads EL.190.35 rather than190.53. Preserve prior record; primary must separately review numeric withdrawal and unit authority. IMG1224 is not used as resolving support. Numeric glyph withdrawal only; prior value/notation/unit stay historical and no physical geometry or governing revision is selected.
