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 locator review after catalogue/OCR of <=1000px JPEG65 derivative of public/archive/drawings/complete-upright/IMG_1109.webp. Primary lettering upright; no complete region review claim. Access-image normalized regions. No model geometry inferred. Partial timed visual review: Source-local printed evidence only; no accepted building transform, installed quantity, or reconstructed geometry. Prior verified measurements omitted; unresolved endpoints and companions retained. Partial timed visual review: Additive selected-region review. Prior verified records reused without duplication; no accepted geometry. Partial timed visual review: undefined Partial timed visual review: Bounded original printed witness review; no governing issue selected. Partial timed visual review: Bounded upright native crop; regions mapped back to normalized full reading frame corresponding to access image. Original master EXIF is stored independently and was not applied as an automatic transform.

Highlighted reading: 11 TREADS @ 10½″ = 9′-7½″. Printed left-flight run, no inferred riser height. Source-local only; not accepted installed geometry.

Remaining car/shaft/flight chains, exact wall/cab/finish boundaries, first-floor counterpart, right-edge cut-off details and revision authority.
Installed instance allocation and physical building registration remain unresolved.
Source-local extraction only; no geometry authoring, modeling check or whole-building acceptance.
