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.

W225 documents lower-story Stair E conditions and remains a separate extraction.

W228 is required before authoring tread, riser, nosing, railing and connection profiles.

Both statements are printed on W226. Neither is discarded or averaged; physical sixth-to-seventh flight geometry remains withheld.

One complete source and sequential crops from the same photograph were inspected. Pixel distances were not used as architectural dimensions.
Three source-backed seventh-floor controls are retained as regional/conflicting evidence pending section-to-plan boundary registration.

No non-collinear source-to-plan control set has passed overlay and held-out residual checks.

The sixth-to-seventh riser-count conflict, missing W228 construction reconciliation and missing source-to-building transform prevent physical authoring.
