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. Partial: Third floor plan boundaries, room identities, opening candidates and printed control chains. Third-floor outer trace reused only as a parent of the analytical registration curtain. Confirmed Stair D identity, source handedness, third-floor elevation title, and candidate C68/C82-to-perimeter alignments. Existing third-floor door topology reused only. Reused the provisional level-3 Stair E plan envelope as one input to a cross-floor median diagnostic envelope. Partial timed visual review: Bounded text-first follow-up; ten sequential inspections total across nine derivatives including one W-6 same-source core crop. No accepted physical geometry. Existing verified readings omitted. IMG_1209 uses prior closeout text only. Partial timed visual review: Prior verified extraction reused without duplication; selected new properties only. No full-coverage or physical geometry claim. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Third-floor source-local Men's339/adjacent janitor and service annotations. Raw0; access WebP's270-degree orientation not used. Partial timed visual review: Text reuse only: floors-2-3 topology records B/D/E only on third floor and explains access WebP rotation 270° from upright raw master. No whole plan reopened.
