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 visual review of public/archive/drawings/complete-upright/IMG_0999.webp after catalogue and OCR. Coordinates are normalized access-image coordinates before any rotation. Actual access image requires 0 degrees rotation to read. Selected evidence only; no geometry/modeling inference. Cropped companion sheets visible behind foreground drawing are excluded. Partial timed visual review: undefined Partial timed visual review: Additive detailed follow-up after OCR and prior package comparison. Nine sequential access derivative inspections; IMG_1003 existing specification readings reused without duplication. Coordinates refer to unrotated access image. Only selected readable evidence; no model geometry or full-extraction claim. Partial timed visual review: Bounded fine-detail review; access-image coordinates remain normalized before actual stated clockwise rotation. Prior verified readings reused without duplicate extraction. Partial timed visual review: Targeted fraction review; source-local readings only.
Highlighted reading: Turned. Top newel terminal dimension line carries turning instruction.
