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.

3 ft
Drawing notation: 3′0″ × 7′0″
Printed on the swing leaf in the typical 3rd–6th-floor plan; nominal door designation, not an established rough or clear opening.
7 ft
Drawing notation: 3′0″ × 7′0″
No door schedule/type mark was securely identified in this pass.
1 count
Single leaf and swing arc shown in the entry-wall opening.
In type axes the hinge is at the smaller-v jamb; the open leaf projects toward -u. No numeric jamb station is inferred.
Relational host only. New analytic host identity has no accepted endpoints or thickness of its finished assembly.
Drawing notation: Visible core threshold or landing door
Reused existing third-floor topology observation; this source was not reopened in the present pass.
