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.

Alternate photograph sheet identity
DRAWING W224 / DETAIL OF STAIR D AND FAN ROOMCorrects the locator-only catalog title; IMG_1261 is another photograph of W224, not merely a roof plan.

Alternate W224 photograph. Printed controls and the sixth-floor landing exception are corroborated; every candidate building transform remains conditional on explicit column and wall-face offsets.

Ordinary-floor plan applicability
3RD, 4TH, 5TH & 6TH FLOOR PLANThe candidate placement uses only the ordinary third-through-sixth-floor type; second, seventh, roof and fan-room variants remain separate.

1'-4" (4'-4" 6TH FL.)The clearer photograph corroborates the witness and its stair-side wall endpoint but still does not distinguish the rough wall line from the applied finish line; epsilonX remains null.
