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.
Gross stair assembly envelope only; exact floor opening, flight geometry and landing elevations remain unresolved.

The numeral is secure; endpoint semantics are a separate unresolved property.
Drawing notation: 1′4″
Dimension lies between the C82/C68 axis and right stair-wall reference. Parenthetical sixth-floor variant is excluded. Exact inner/outer/finish-face endpoint still needs confirmation before deriving insertion coordinate.

Printed scalar only; do not subtract from C82 to obtain a finished inner corner until the witness endpoint is identified.

The ordinate arrow meets the lower hatched wall area. It is not securely established whether the referenced line is the finish face, structure face or another wall datum.
