The measured building.

W257 to W8 placement registration gate

No W257 component receives a building transform. W238 now independently classifies the W257 north wall as the W8 public-foyer face, but the remaining lateral hand, south/bench boundary, and metric controls are insufficient. The four-corner projective diagnostic remains non-authoring because its fitted controls are provisional and its bench-zone checks are circular. Only the north/public-foyer face is independently classified; the lateral side hand and the remaining fitted intersections are not independently identified finish-face controls. The W8 Room 602 south boundary is a coarse provisional trace through the bench/dais composition rather than a verified room-wall face chain. W257 combines the east and west wall elevation subject; W238 resolves the north/public face but does not resolve the lateral east/west hand. The four fitted controls have zero residual by construction and therefore do not validate the correspondence. The four candidate bench-zone comparisons were selected using the same interpreted bench/dais geometry and are not independent held-out checks. The diagnostic residuals are below the W8 trace uncertainty but cannot overcome incorrect or circular feature classification. No printed coordinate chain shared by both W257 and W8 has been reconciled.
