Six Values of p, One Parameter Counted: I Charged a Late-Time Growth-Suppression Paper for the Shape It Scanned, and Its Two-Sigma Solution Fell to 1.6

Prices Queue-2 item Q2-18, arXiv:2505.09176 (Terasawa, Takada, Kurita & Sugiyama, late-time suppression of structure growth as a solution for the S8 tension), on its verified abstract claim, the TSI store record, and the full text.

Abstract
