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. Partial timed visual review: Partial text-first and one sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1187.webp. Coordinates normalized to unrotated access image; clockwise correction given by rotationDegrees. Selected regions only, not full measured extraction. No modeling authorized. Partial timed visual review: Selected bounded crop only. Prior verified values retained. Partial timed visual review: Additive selected region follow-up; previously verified findings omitted. Dimension witnesses apply only to depicted source-local spans. Extraction partial; modeling not started.
