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.

Four printed 160 ft 10 in exterior-face overall control intersections; Raw-raster orientation and cardinal mapping; Elevator 1 and 2 outer-enclosure line candidates; Elevator 3 and Stairs B/D/E bounded locators; Cross-sheet X checks for Elevators 1 and 2; Cross-sheet center check for Stair E Three printed held-out W-6 interior/structural spans and seven candidate source picks checked against the frozen registration. Rooms 401–407 source-space candidate cells, corridor-side door interruptions, west-facade printed chains, vault and local corridor controls; 16 crop receipts retained in the research package. Bounded Room 402 four-side candidate face loop, three door interruptions, façade opening, and distinction from through-running diagrammatic lines. Rooms 421–427 source-space candidate cells, eleven separate wall/face traces, eight door interruptions, seven east-facade openings, seven exact 14-foot facade chains, two closet labels, one unresolved fixture symbol and two printed notes; eleven bounded crop receipts retained in the research package.

Numeric value unresolved
Large unoccupied central court/opening. Polygon is a coarse source-space inner-edge trace, not an exact structural opening.
Decoded raw raster is upright; the JPEG EXIF Rotate 90 CW tag is explicitly ignored for this source package.
Numeric value unresolved
The polygon is a coarse source-space circulation band and intentionally does not close around each lobby/core offset.
