The measured building.

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.

Source photographs: 464
Identified objects: 4872
Verified printed values: 12046
Disputed values: 20

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 sequential locator review using <=1000px JPEG derivative of public/archive/drawings/complete-upright/IMG_1228.webp. Access-image normalized regions before rotation; rotationDegrees is clockwise turn required for primary lettering. Locator coverage does not mean complete regional extraction. No modeling. 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: Full architectural region inventory by existing object/property sources, with explicit pending work. Reused bounding regions do not certify exhaustive visual coverage.

All remaining fine dimensions, notes, callouts, schedules and revision authority need regional review.
Accepted finished/rough/structural faces, material extents and closed physical bounds remain unresolved.
Source registration, held-out checks, companion applicability and installed quantities remain unaccepted.
Remaining cap-roof inset identities, full intake section chain, lower-right roof region and exact layer/roof field applicability are not closed.
Screen material species unresolved after MESH note reread; do not infer Monel.
