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. W105 overview plus four targeted crops (level chain, upper court, lower boiler band, C–C/D–D); selected printed levels and void topology. Partial timed visual review: Source-local printed/observed section controls, independent local ceiling/roof and finish scopes; no building geometry approval. Partial timed visual review: Source-local architectural evidence only; no physical registration, installed quantity or accepted geometry. Existing verified measurements omitted; conflicting locator readings preserved. Partial timed visual review: Text-only existing main-sections and prior parallel reports reused; no new visual call.
