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. Coarse floor topology, Main dimension/control chain, selected printed room widths and local corridor condition Fifth-floor outer trace reused only as a parent of the analytical registration curtain. Reused the provisional level-5 Stair E plan envelope as one input to a cross-floor median diagnostic envelope. Stair E fourth-to-fifth physical flight/landing/shaft gate; no solid authorized. Stair E fourth-to-fifth physical flight/landing/shaft gate; no solid authorized. Stair E fourth-to-fifth physical flight/landing/shaft gate; no solid authorized. Stair E fourth-to-fifth physical flight/landing/shaft gate; no solid authorized. Partial timed visual review: Selected upper-right grille, scale-details and general-note region only; normalized coordinates on the 2200 by 1650 complete-upright access derivative before rotation. Partial timed visual review: Prior verified extraction reused without duplication; selected new properties only. No full-coverage or physical geometry claim. Partial timed visual review: Additional source-local room identity and dimension endpoint review only; no geometry acceptance. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Isolated Prisoners Cell Grille type detail; full fifth-floor plan reused. Partial timed visual review: Text reuse only: fifth-roof-topology already records independent B/D UP20/DOWN20 and local plan-span properties; no reopening or duplication.
