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. Initial control subset: two exterior overall spans, two column-bay chains with end offsets and arithmetic closure, named spaces, three elevator/stair identities, selected heights and scale-pit dimensions. Provisional registration; coarse footprint trace of named rooms, three elevators, stairs A/C/E, Registry storage stair, loading recess, platform, scale pit and visible door relationships. Partial W3 first-floor core host-boundary and landing audit. Main foyer, immediately adjacent Public Lobby screen row, and opposite Main Street door row only Public-lobby furniture band reviewed for printed DESK symbols, count, relative position, orientation and room containment. Four candidate centers were picked and transformed through the existing provisional registration. Reused verified W3 public-lobby DESK count, room containment, horizontal-axis alignment, east-west long axes and provisional registered centers; no drawing reopened. Bounded W218 plate type and W3 plan-candidate gate; not an installed desk placement. Independent W3 confirmation of Q–Y identities, order, host wall, terminal anchors and handedness. Bounded first-floor elevator audit: FIRST FLOOR PLAN. Bounded first-floor elevator audit: FIRST FLOOR PLAN. Bounded first-floor elevator audit: FIRST FLOOR PLAN. Column identities, first-floor elevator contexts and terminal Main dimension-chain controls only. Elevator detail-to-W3 physical-placement gate: FIRST FLOOR PLAN. Partial entrance-registration review: The prior W3 trace is retained as a provisional entrance-center witness with 2-foot uncertainty. Its traced 4.602-foot length is not used as the finished or operating width. First-floor enclosed outer trace reused only as a parent of the analytical first-story registration curtain. Reuse of existing text/registered property data only; no new image review. Named PUBLIC LOBBY and printed ceiling-height reading. Normalized from an existing text re-audit; this import did not reopen the source image. Partial W3 review: Bay P wall endpoints, label/handedness and independent doorway-center check. Main entrance stair plan only: centerline, upper run endpoint, lower run endpoint, rear landing reference and lower outside-edge width witnesses. Reused registered Main entrance stair centerline, run axis, and endpoints for rail-axis placement. prior text package reused; image not reopened; bounded source review. Center entrance bronze-leaf physical placement gate; one IMG_1298 region checked against prior entrance packages.
