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 sequential visual review after catalogue and OCR using 1000px quality65 JPEG locator derived from public/archive/drawings/complete-upright/IMG_1065.webp. Access image lettering is upright. Normalized regions reference original access image. No modeling or exact geometry inferred. Partial timed visual review: Source-local additive detail evidence only. No installed quantity, room polygon, revision authority or accepted model geometry established. Partial timed visual review: Source-local flagpole parapet chain rereading; conflicting prior value preserved, no dimensions transferred to model. Partial timed visual review: undefined Partial timed visual review: Raw master EXIF 1 is sideways. First raw crop was an orientation locator, not an upright fine-chain extraction. Second crop rotates raw raster 90 degrees clockwise, then selects normalized upright region. All new regions below refer to the 3024×4032 upright raster. Partial timed visual review: undefined
