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 review of public/archive/drawings/complete-upright/IMG_1028.webp after catalogue/OCR and existing observations. Coordinates are normalized access-image coordinates before rotation. Actual reading rotation 90 degrees. Foreground drawing only. 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.
Highlighted reading: SIDE ELEVATION. Assembly-local source reading; no whole-room or installed-instance geometry inference.
