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 first-pass review of public/archive/drawings/complete-upright/IMG_0984.webp. Access-image normalized coordinates are unrotated derivative coordinates; rotationDegrees records clockwise correction needed for readable text. No model geometry authorized by this evidence. Partial timed visual review: Text-only reuse; no pending source readings and no new image inspection in this batch. Partial timed visual review: Additive remaining-region review; source regions use original access derivative coordinates. Reuse prior verified evidence; preserve conflicts separately. No physical geometry inference. Partial timed visual review: undefined
