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: Additive remaining-region review 2026-10-11; prior packages, queue and OCR read before sequential derivative inspection. Regions in native derivative coordinates. Ten inspections including one notes crop across this batch. Partial extraction only; no model changes. Partial timed visual review: Source-local construction detail only; installed instance registration and complete geometry unresolved. Partial timed visual review: Source-local printed construction property; no room geometry, installed quantity or accepted model inference. Partial timed visual review: Bounded follow-up on selected source witnesses only. Partial timed visual review: Bounded first pass of public/archive/drawings/complete-upright/IMG_0963.webp. Catalogue/OCR consulted first; prior reference search found only review queue. Actual derivative orientation visually verified. Raw access-image coordinates precede clockwise presentation rotation. Review partial; no modeling.
Highlighted reading: 11/16. Source-local construction detail only; installed instance registration and complete geometry unresolved.
