Ten Percent by Adoption: What the Assumed Shadow Tolerance Costs the Higher-Curvature Sensitivity Claim

Prices arXiv:2608.20581's first-order higher-curvature shadow sensitivity at its HTML full text. The bound rests on an adopted 10 percent shadow tolerance, 2.25 times the cited ring measurement's 4.44 percent fractional error and applied to a different object; from the record's printed coefficient formula the bound runs 0.0185 to 0.1325 across the family and diverges at eta = 1, the simultaneous-control threshold is 0.9003 times the shadow-only one, and every figure is first order with no printed truncation error. The nearest house object is paper #602's first-order domain pricing, a different species. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
