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 review of public/archive/drawings/complete-upright/IMG_1053.webp after catalogue/OCR and existing observations. Coordinates are normalized access-image coordinates before rotation; actual clockwise reading rotation 0 degrees. Foreground only; no installed geometry established. Partial timed visual review: Depicted detail only; printed floor association does not establish installed room instance, quantity, placement or accepted geometry. Conflicting earlier readings retained separately. Partial timed visual review: Depicted drawing detail and annotations only; installed registration, quantities, revision authority and accepted geometry remain unresolved. Earlier records preserved. Partial timed visual review: Source-local witnesses only; physical geometry and installed quantities remain unapproved. Partial timed visual review: Source-local evidence only; no accepted geometry or installed assignment.
Highlighted reading: PLASTER LINE AT HEAD. Upper doorway detail labels a separate plaster line at head; no thickness or world-coordinate inference.
