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_1188.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: Additive targeted derivative crop follow-up after prior packages, queue and OCR. Ten sequential single-image inspections total. Coordinates normalized to unrotated complete-upright access image; IMG_1194 crop rotated 180 degrees for reading. Selected source evidence only; no accepted geometry. Partial timed visual review: undefined
