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. Independent registration, named and numbered room/core locations, coarse boundary traces and selected visible door relationships. Partial timed visual review: Additive bounded follow-up; coordinates normalized to unrotated access raster. Original plan/topology records retained. No model acceptance or complete-sheet claim. Partial timed visual review: undefined Partial timed visual review: Source-local partial review; no physical coordinates accepted. Partial timed visual review: undefined Partial timed visual review: Basement Stair C / Elevator 2 wrapper and selected local witness, not a complete basement extraction.
