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.

Stair. A Basement 1St. & 2Nd Floors

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass sequential review of public/archive/drawings/complete-upright/IMG_1108.webp through 1000px maximum JPEG quality65 locator after OCR/catalogue and existing reports. Actual clockwise reading rotation 0 degrees. Coordinates normalized access-image before rotation. Fine blurry readings remain null; no modeling. 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: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage. 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 tread-spacing portion of same note. Source-local only; not accepted installed geometry.

Remaining risers, treads, flight widths, landings and rail sizes across all levels.
Companion W228 and floor/finish datum classification.
Installed instance allocation and physical building registration remain unresolved.
Source-local extraction only; no geometry authoring, modeling check or whole-building acceptance.
