Prices Queue-2 item Q2-20, arXiv:2507.19585 (Zhang et al., testing the AGN unified model with simulated CGM emission lines), on its verified abstract claim, the TSI store record, and the published MNRAS full text. The load-bearing imported step is the unified model itself as the mocks' construction: both types are the same ten FIRE haloes with the same intrinsic SED, differing only by sightline through an imposed cone with half-opening angle restricted to 50/60/70 degrees. On the paper's own numbers: 180 mocks per line factor as 10 systems x 3 placements x 3 Delta values x 2 sightlines; the headline observables are null (Welch p = 0.45 area, 0.65 luminosity); the paper's printed alpha_w example inverts the type ordering at 0.30 sigma when Delta is uncontrolled, and Delta is measurable only if the model is assumed; the >=75-nebulae requirement is a with-replacement resampling of a 90-mock per-type pool built on 10 haloes; the resonant-scattering sigma_v correction (~100 km/s) is 5x the ~20 km/s type offset. DERIVED-INDEPENDENT. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
