The Calibration Carries the Normalization: What the Adopted Cluster Mass Calibration Costs the Reconstructed Matter Density

Prices the adopted cluster mass calibration behind arXiv:2603.25851's non-parametric Omega_m(z) reconstruction. The three 103-cluster normalizations span 0.061, which is 25.4 percent of their midpoint, 3.98 times the mean printed statistical error, and a 2.96 sigma mutual disagreement between the extreme calibrations; the evolution-shape verdict costs the calibration zero, as printed. The ordered corpus search names paper #272's Galactic-model swing as nearest house object on the species of step. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
