Prices Queue-2 item Q2-17, arXiv:2504.18625 (Autieri, Berti, Spinelli, Haridasu & Viel, weighing neutrinos with 21cm intensity mapping at the SKAO), on its verified abstract claim, the TSI store record, and the full text. The load-bearing imported step is the fiducial astrophysics: every abstract headline (Sigma m_nu < 0.287 eV auto alone, < 0.105 eV with Planck, < 0.116 / < 0.117 eV cross + Planck) is the paper's nuisance-fixed number, a condition the abstract never states. The paper's own Table 4 free-nuisance values loosen every limit by 20.0-48.1%, revert the fiducial-0.1 eV detections (0.098 +/- 0.022 eV) to upper limits, and pull the fiducial-0.4 eV cross-correlation centres 11.9-13.6% below the input mass. The limit also rises with the imported fiducial (slope 0.75 eV per eV) and sits on a 0.059 eV prior floor that is 20.6% of the headline. DERIVED-INDEPENDENT. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
