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 selected remaining-region review; prior queue, OCR and packages consulted. Prior verified readings reused without duplication. Partial extraction only; no modeling. Partial timed visual review: Bounded additive remaining-region review; prior queue, OCR and reports consulted. No full coverage or modeling. Partial timed visual review: Bounded additive regional inventory; historical room/type marks remain separate from stable dataset object IDs. Partial timed visual review: Bounded first pass of public/archive/drawings/complete-upright/IMG_0972.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. Partial timed visual review: Bounded source-local reading only. Raw frame, inspected encoded crop and actual reading transform are independent. No installed geometry, governing revision or exhaustive source coverage established.
Highlighted reading: 7′-0″. First-pass property only; remaining detail and endpoint/component associations require review.
