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. Independent registration, named and numbered room/core locations, coarse boundary traces and selected visible door relationships. Eighth-floor outer trace reused only as a parent of the analytical registration curtain. Partial timed visual review: Sequential 2200px WebP review; additive selected remaining properties only. No geometry acceptance. Partial timed visual review: Selected additional source-local property review; normalized regions reference unrotated access derivative; no metric transform. Partial timed visual review: Attic Stair D compound branch and ceiling-door adjacency; W224 companion required before any regional/roof connection. 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. Partial timed visual review: undefined
