## Statement

Feeding the measured NuFIT solar angle through the same first-row formula gives the separate diagnostic value |Vus| = 0.22687.

## Caution

This measured-input diagnostic is not an independent prediction and does not upgrade the selected first-row route.

## Primary source

Paper 3, §2, Measured-angle diagnostic, PDF p.49: "Feeding the measured NuFIT solar angle through the same formula gives the separate diagnostic value 0.22687. Against the |Vus | comparator error alone that is +3.01σ; propagating the NuFIT θ12 error as well gives about +1.0σ (0.97–1.00, house recompute A1641), and only the propagated figure√ is a distance (Rev32.9)."
