The HAL (Hyper-Anisotropic Luminal Physics) framework predicts an effective gravitational constant Gₑff = GN/C0, where C0 = 1 + alphaₑm = 1. 007297. Since quasinormal mode (QNM) frequencies scale as 1/ (G M), this implies a universal fractional shift deltaf/f = alphaₑm = +0. 7297% relative to general relativity. For the remnant black hole of GW250114 (Mf = 58 Mₛol, af = 0. 77, SNR = 76), the HAL prediction for the dominant (2, 2, 0) mode is f₂20HAL = 334. 3 Hz versus the GR value of 331. 9 Hz, a shift of 2. 4 Hz. The LVK analysis constrains deviations to within a few percent, leaving the HAL prediction compatible with current data. Detection requires SNR ~ 420, achievable with the Einstein Telescope. Combined with the spin-memory correction epsilon = +alphaₑm derived in prior work, the HAL framework now carries two independent, universal, parameter-free gravitational predictions both equal to alphaₑm = +0. 7297%. Simultaneous measurement of both constitutes a definitive test.
