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. IMG_1327 bounded typical roof slab section: candidate dimensions remain unreviewed; no field placement. Main roof physical field gate; one IMG_1327 detail inspected after text audit, no accepted solid. Partial timed visual review: Selected new access-derivative regions inspected; previously verified evidence reused. Partial extraction only. Partial timed visual review: Sequential access derivative inspection for detail assignment and hooked-end note; no numeric fraction resolved. Partial timed visual review: Prior evidence reused; only selected remaining source-local regions reviewed. No historical placement or accepted physical geometry. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Source-local schedule, fabrication or connection evidence only; no installed geometry or architectural acceptance.
