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.

Fourth-floor provisional trace coordination
UnresolvedThe provisional fourth-floor trace spans approximately X 38.7–60 and Z 33.9–46.4 feet, while the W224 zero-offset candidate spans X 34.5–50.3333 and Z 39–47 feet. The mismatch is exposed in preview and is not averaged away.
