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: Explicit source-local region inventory and additive bounded property review; catalogue labels are discovery aids. Original and colored handwritten revisions remain separate. No physical geometry authoring. Partial timed visual review: Additive bounded detail review, 2026-10-11. Existing verified extraction reused; no building geometry accepted and no full-sheet completeness claim. Regions are normalized raw access-image coordinates before presentation rotation. Partial timed visual review: Bounded visual first pass of public/archive/drawings/folder-195/IMG_0907.webp. Catalogue and OCR consulted first; no prior research reference found. Partial extraction only, no modeling or completeness claim. Regions refer to raw access-image pixels before the stated clockwise presentation rotation.
