The de Sitter-Unruh modified-inertia proposal sets the MOND acceleration scale by the dark-energy density, a0 = cHLambda/Z = (c/2) sqrt (G rhoDE) = c² sqrt (Lambda/32pi) ~ 9. 36e-11 m/s² (Z=sqrt (32pi/3) ~5. 789), so a0 evolves as a0 (z) /a0 (0) =sqrt (rhoDE (z) /rhoDE (0) ) on the DESI-preferred evolving-dark-energy branch. This note draws one consequence and confronts it with a live anomaly. Evolving dark energy implies a rolling quintessence field; the swampland Distance Conjecture then predicts a tower of states whose mass tracks that field. The framework's vacuum scale EdS = rhoDE^ (1/4) ~ 2. 24 meV sits, uniquely among Standard-Model scales, within one order of magnitude of the neutrino mass scale (the electron is 1e8, atomic-MOND accelerations 1e33, away) -- so the neutrino is the one place the framework's de Sitter vacuum and a particle scale meet. IF the lightest neutrino is the lightest tower state, its mass grows from past to present, locked to a0 (z) with no free amplitude: propagating the public DESI w0wa posterior gives mₙu (z=3) /mₙu (0) ~ 0. 59-0. 75, and a mass that FREEZES by recombination. The testable consequence is sharp: the CMB imprints a neutrino 28-46% LIGHTER than today's, so a constant-mass fit to CMB+BAO under-counts the late-time mass -- yielding an inferred Sigma mₙuᵉff ~ 0. 032-0. 042 eV when the true present-day value sits at the normal-ordering oscillation floor (0. 059 eV). This is the right sign and right rough magnitude to be the DESI 'negative effective neutrino mass' anomaly. LIMITS stated plainly: nothing here DERIVES mₙu (the absolute scale is free; the meV match is generic to any rhocosmic^ (1/4) ) ; the signature is partly DEGENERATE with the standard 'dynamical dark energy mimics negative mass' reading; the framework-distinctive content is the LOCK of the mass evolution to rhoDE^ (1/2), testable only by a joint CMB-vs-late-time Sigma mₙu fit constrained by a0 (z). This is a prediction about the NEUTRINO/DARK SECTOR ONLY -- NOT a theory of everything (the charged-lepton and quark masses remain untouched and walled). It is decided by the same DESI w (z) gate as the a0 (z) prediction, sharpened by CMB-S4 + DESI-DR3/Euclid growth (~2027-2030), and it DIES if DESI converges to w=-1. All numbers are reproducible from the public repository. Supplements the author's published one-parameter de Sitter-Unruh papers (DOI 10. 5281/zenodo. 20973740, 10. 5281/zenodo. 20965016, 10. 5281/zenodo. 20938891) and does not restate or strengthen any claim about deriving the Standard Model.
