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.

Landing topology
TWO RISERS OCCUR IN LANDING2 riser-count
Section and elevation captions explicitly establish two risers within the landing. W228 does not identify the Stair E storey to which this condition applies.

W226 sixth-to-seventh reconciliation status
Candidate only: 20 ordinary risers + 2 landing risers may explain 22 totalArchitectural inference from W226's 20-up/22-down readings and W228's explicit two-riser landing detail. No callout or checked geometry yet proves that this W228 condition applies to the level-6/7 Stair E connection.
