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.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
This wording establishes Broadway/upper-story scope but not equivalence to W-207.
Drawing notation: DETAIL OF UPPER STORIES — BROADWAY ELEVATION
W-209 named library/upper-story special condition; no generic W207 fourth-floor applicability.
The named library condition is retained and prevents generic propagation.
Drawing notation: SECTION THRU LIBRARY WINDOW HEAD
W-209 named library/upper-story special condition; no generic W207 fourth-floor applicability.
No image-space distance is converted from this scale.
Drawing notation: SCALE 3/4" = 1'-0"
W-209 named library/upper-story special condition; no generic W207 fourth-floor applicability.
171.75 ft
Broadway/Main-side upper-story datum; it does not place the wall horizontally.
Drawing notation: FIN. 7TH FL. EL. 171.75
W-209 named library/upper-story special condition; no generic W207 fourth-floor applicability.
Not established. Treat as a named special condition until a reviewed cross-reference proves otherwise.

173.75 unlabeled-datum
Library-head detail's own right-hand seventh-floor datum token, visually confirmed in a second enlarged crop. Prior bway-W209-seventh-floor-line 171.75 has a different source box [0.55,0.45,0.77,0.75], at the main wall section. Preserve distinct witnesses; do not withdraw or select a governing datum. The printed token has no adjacent explicit unit.
