Assembly-local source reading; no whole-room or installed-instance geometry inference.
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 sequential visual review of public/archive/drawings/complete-upright/IMG_1033.webp after catalogue and OCR. Regions use unrotated access-image coordinates; rotationDegrees gives clockwise turn needed to read primary lettering. No room geometry or modeling inference. Partial timed visual review: Follow-up visual derivative review. Coordinates normalized before stated clockwise rotation. Assembly-local evidence; installed instances and room geometry remain unregistered. Partial timed visual review: Lower-end plan scalar reading only; bronze material and Stair A/B relationships reused from prior evidence. Partial timed visual review: Selected source-local witness/callout review only; original and annotation layers kept separate. Partial timed visual review: Fractional dimensions in upper marble section and lower-end rail plan; previous 18-inch face-of-stone correction retained without duplication.
Highlighted reading: 2'-6". Assembly-local source reading; no whole-room or installed-instance geometry inference.
