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_1107.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 additive printed detail evidence; no installed quantity, operating clear dimensions, room geometry or accepted placement. Partial timed visual review: Source-local printed detail or selected note only. No installed quantity, clear opening, building placement or accepted geometry established. Partial timed visual review: Interior column casing section fine labels only; prior steel-bar dimensions and pipe-duct note correction reused. Partial timed visual review: Column casing corner joint and height witness 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.
