CDN-204 revises the D9 claim boundary, indicating implications for source-side predictions and measurements.
CDN-204 revises the D9 claim boundary after the CDN-203 source-side failure. The frozen switch still has two passed phase-gradient holdouts and one tight source-side point pass, but it is not interval-closed across the below-crossing source branch. The measured source-side floors over delta=0.02, 0.06, 0.07, 0.08 are nonmonotone, while the frozen source prediction decreases smoothly. CDN-203 sits +0.017515 above the local 0.06-to-0.08 interpolation and fails the frozen source prediction by +0.019182.
