Oscillation experiments require Sum m_ν of at least 0.059 eV (normal ordering) or 0.10 eV (inverted). DESI BAO combined with the CMB now bounds the sum below 0.056 to 0.072 eV, excluding the inverted ordering and pressing under the normal-ordering floor, a 2.5 to 5σ conflict with laboratory physics. Worse, when the effective mass is allowed to go negative as a diagnostic, the data prefer it: the sky shows more lensing and clustering than even massless neutrinos should allow.
ΛCDM fixes the geometry with a constant Λ and the late-time growth with GR plus catalogued matter, leaving Sum m_ν as the only knob that can adjust late-time lensing and small-scale power. Any unmodeled lensing-like excess or geometry shift is therefore forced through the neutrino parameter, and the fit responds by driving the mass below zero. The model has nowhere else to put the signal.
SCT replaces the hot-dense-center with a superluminal collision, and with it two ingredients the neutrino fit is missing. First, the coherent mesh: Φ_eff = Φ_local + Φ_mesh (P51) adds real lensing convergence beyond the catalogued matter (P50, P52, P53). Massive neutrinos erase small-scale lensing power; the mesh adds it. A fit whose only lensing dial is Sum m_ν reads the mesh excess as negative neutrino mass, which is precisely the diagnostic the data return.
Second, the dynamical ratio Λ_eff(x,t) = C × Λ_parent / λ_local (P17, P19) shifts the expansion geometry that BAO calibrates. The DESI evolving dark energy preference and the neutrino bound are coupled symptoms of the same omission: it is already known that opening the dark energy sector relaxes the cosmological bound to roughly 0.16 eV, comfortably above the oscillation floor. With both SCT terms in the model, neutrinos are no longer the scapegoat parameter, and the cosmological inference returns to compatibility with the laboratory floor.
This is the same pair of mechanisms that resolves the Hubble tension, the DESI w₀w_a preference, and the lensing-amplitude anomaly, and the strong observed correlation between the A_lens excess and the neutrino bound is exactly what a common mesh origin predicts. Neutrino physics itself is untouched: SCT needs no sterile states, no mass-generation exotica, and no conflict with oscillation data.
If a fit that marginalizes over a lensing-amplitude term and an evolving dark energy sector, the two SCT-shaped degrees of freedom, still drives Sum m_ν below 0.059 eV at more than 3σ with DESI Year 5 and CMB-S4 data, the SCT reconciliation fails: the conflict would not be an absorption artifact. Conversely, a laboratory determination (KATRIN-class) of a mass sum that cosmology under SCT corrections still excludes would falsify the corrected inference chain.
