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.

Extraction: Reviewed · extraction partial. C10/C11/C12 perimeter spans, C68/C82 connected framing paths, and C70/C72/C84 local perimeter spans. W400 includes C84/C96 terminal span. Partial timed visual review: Bounded source-reading review only; no full-source or geometry acceptance. Partial timed visual review: Text-only reuse, no new visual inspection. Partial timed visual review: Access derivative actually sideways. Recorded regions remain encoded access-image coordinates; rotate clockwise 270 degrees to read. Existing C68/C82 controls reused. Partial timed visual review: Targeted source detail only. Master orientation recorded independently from access derivatives. Region bounds are crop locators, not physical geometry. Partial timed visual review: undefined Partial timed visual review: undefined
