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.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.

Source-space control only; no metric or building transform is accepted.
Several end-bay values south of Room 401 are visible but their digits and applicability to Room 401 versus the elevator/corner bay are unresolved.

Several interior vertical-chain strings are partly legible, but digits, endpoints and room-by-room applicability cannot all be held together securely. None is promoted as a room clear dimension.

Observed swing direction is recorded, but handing requires an agreed approach-side convention and remains null.
Drawing notation: Rooms 421-426 have page-right/inward swings; Room 427 has two differently oriented boundary openings.
