The 72 Hertz That Divides to Two: I Ran an f(R,T) Echo Paper's Printed Numbers Through Its Own Frequency Formula, and the GW170817 Match Broke in Exactly the Leg That Carried It

Prices Queue-2 item Q2-12, arXiv:2610.30770 (Jayawiguna, Sabian, Ramadhan & Sulaksono, axial perturbations of extended Tolman III in f(R,T) gravity), on its verified abstract claim, the TSI store record, and the full text. The load-bearing step is the assumed identification of a constant-density star, at beta = 0.4662702 and chi = 0.96 pi, as a neutron star at the NICER radius R = 11.4 km matched to GW170817's reported 72 Hz echo frequency. The audit is arithmetic on the paper's own printed chain: the GR leg is internally exact (tau_tilde 25.3 -> 519.7 Hz vs printed 519 Hz), while the f(R,T) leg, exact through its printed tau_echo = 7.18e4 km = 239 ms, returns f_echo = 2.09 Hz under the paper's own eq. (63), not the printed 72.11 Hz -- a factor 34.5 break in the leg that carries the headline. The assumed object has M = beta R = 3.60 solar masses at 99.65 percent of the model's allowed compactness maximum. DERIVED-INDEPENDENT. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
