Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.
464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

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.
Numeric value unresolved
The symbol establishes an opening identity only; dimensions and host geometry remain unreviewed.

Door symbol at Sixth/east/page-left end of B landing opens to adjacent circulation. Confirms existing analytical opening identity; exact connected corridor boundary and prior coarse locator need a later face audit, not a coordinate repair here.
