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_1063.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: Prior-report reuse only; full sheet not reopened or treated as equal revision to close photographs. Partial timed visual review: undefined Partial timed visual review: Two sequential master crops of Main interior parapet elevation. Raw raster and lettering upright (EXIF 1). Source page-right remains page-right; no compass or world-axis assignment. Partial timed visual review: undefined
