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.
