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_1003.webp after catalogue and OCR. Regions are displayed access-image coordinates. No exact room geometry or modeling inference. Partial timed visual review: Bounded source-local shop detail/type evidence. No accepted geometry, complete extraction, installed quantity or inferred floor assignment. 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: No new image inspection; prior verified complete specification transcriptions reused. Thickness, slot spacing and materials not duplicated; physical component assignment and all companion/revision checks remain open. Partial timed visual review: Existing text reused; no new visual inspection or duplicated measurements.
Highlighted reading: 3 ply Bottoms. Selected visually read printed evidence; partial review; assembly-local scope.
