Oscillation Phase Shifts Over Cosmological Baselines in a Bounce Frame

This paper computes a specific neutrino quantity in a cosmology whose collapse is regulated by a maximum density, the Aldred Limit evaluated on its neutron branch at 9.72e+54 grams per cubic centimetre. Neutrinos from distant astrophysical sources arrive as an incoherent mixture of mass states, because the oscillation phase accumulated over gigaparsec baselines is astronomically large. Whether a frame effect could restore partial coherence or shift the averaged flavour ratios is a quantitative question about the size of the extra phase. The calculation gives the following headline values: dm2_eV2 = 0.0025, baseline_Gpc = 1.0, energy_GeV = 1.0, standard_phase_rad = 9.774905e+19, phase_mod_fraction = 1e-38, cycles = 1.555724449003683e+19. Each value is obtained from stated assumptions by the deposited script and is compared with published observational values where such values exist. Where the computed frame effect is far below observational reach, that negative result is stated plainly rather than softened. This study is simulated and computed from stated assumptions; it is not a measurement.
