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.

Full source and four bounded regions reviewed Partial timed visual review: Additive bounded remaining-region review; ten sequential single-image access derivative inspections overall. Source-local properties only; prior conflicts retained; extraction partial, modeling/checking unchecked. Partial timed visual review: Text-first follow-up: existing detailed report/queue/OCR reused; source image not reopened. No new verified-property duplication. Partial timed visual review: undefined Partial timed visual review: West-wall opening witness fraction 3′-3¾″. Source-local extraction only; original/revision and installation layers remain separate.
