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 room, court, shaft, stair and visible-door topology with independent provisional registration. 29nominal rooms/circulation regions,4shafts (3elevators plus steel stack),5stair envelopes and28selected openings. Sixth-floor outer trace reused only as a parent of the analytical registration curtain. Reuse of existing text/registered property data only; no new image review. Reused the provisional level-6 Stair E plan envelope as one input to a cross-floor median diagnostic envelope. Text-first Room 607 plan-to-millwork wall-elevation registration gate; existing reviewed sources reused without reopening archival images. Partial timed visual review: Sequential 2200px WebP review; additive selected remaining properties only. No geometry acceptance. Partial timed visual review: Additional source-local room identity and dimension endpoint review only; no geometry acceptance. Partial timed visual review: Text-only reuse checkpoint; no image reopened. Prior evidence and unresolved work retained. Partial timed visual review: Sixth-floor Halls604/610 private stair local interfaces, compared text-first with seventh-floor candidates. Partial timed visual review: Selected source questions and verified prior property crosswalk only; no exhaustive region or source completion claimed. Partial timed visual review: Full architectural region inventory by existing object/property sources, with explicit pending work. Reused bounding regions do not certify exhaustive visual coverage.
