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. Coarse room, court, shaft, stair and visible-door topology with independent provisional registration. 31nominal rooms/circulation regions,4shafts (3elevators plus steel stack),8stair envelopes and27selected openings. Seventh-floor outer trace reused only as a parent of the analytical registration curtain. Reused the provisional level-7 Stair E plan envelope and independently read DOWN 22 / UP 20 labels as cross-floor diagnostic inputs. Existing seventh-floor plan room-number evidence reused for cross-source identity correlation. Bounded W-235 to seventh-floor-plan registration gate; component identities remain valid while all source-to-building placements are withheld. Partial timed visual review: Existing appeals audit reused; no image reopened and no duplicate platform records. Partial timed visual review: Sequential full derivative and targeted Court717/716 crop review. Additive source-local relationship verification; existing room dimensions, traced polygons and printed levels are retained without duplication. Geographic directions derive from IMG_1222 compass. No accepted geometry changed. Partial timed visual review: Additional source-local room identity and dimension endpoint review only; no geometry acceptance. Partial timed visual review: Text-only reuse checkpoint; no image reopened. Prior evidence and unresolved work retained. Partial timed visual review: Seventh-floor F/G terminal host sides and west regional short-flight direction. Upright master is raw rotated90° clockwise; access file already upright. Partial timed visual review: Selected source questions and verified prior property crosswalk only; no exhaustive region or source completion claimed. Partial timed visual review: Full architectural region inventory by existing object/property sources, with explicit pending work. Reused bounding regions do not certify exhaustive visual coverage.
