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 1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1197.webp after OCR/catalogue and reports. Actual clockwise reading rotation 0 degrees. Coordinates normalized access-image before rotation. No full-region extraction/modeling claim. Partial timed visual review: Additive targeted derivative crop follow-up after prior packages, queue and OCR. Ten sequential single-image inspections total. Coordinates normalized to unrotated complete-upright access image; IMG_1194 crop rotated 180 degrees for reading. Selected source evidence only; no accepted geometry. Partial timed visual review: Additive closure after queue/OCR/prior-package review. Ten sequential single-image inspections including locator/crops. Regions use unrotated complete-upright access-image coordinates; crop extraction preceded reading rotation. No geometry acceptance. Partial timed visual review: Generic source-local site detail; installed instance geometry, dimensions and registration remain unchecked. Partial timed visual review: undefined
