v2. 0 (May 2026) — major reframing. The original claim of the v1. x series (that the dark-energy scale could be derived from baryogenesis as ρΦ ∼ ρPl η40/3 with C ∼ O (1) ) is explicitly retracted in this version: a rigorous Harvey-Turner audit of the relevant electroweak chemical potentials shows that the factorized doublet product κQ9κL3 ≈ -1. 24 × 10-8, eight orders of magnitude below the value that would be required. The numerical proximity log (ρΛ/ρPl) /logη ≃ 13. 31 ≈ 40/3 is reported as an unexplained coincidence, not as a derivation. What the v2. 0 paper does claim. A minimal canonical scalar field Φ with axion-like potential V = Λ4rec1 - cos (Φ/fΦ), fΦ ∼ M-barPl, kicked to an initial displacement Φi/fΦ = 1 by the Nieh-Yan torsional residue of electroweak baryogenesis, and coupled to the photon through a Chern-Simons operator (cW/4fΦ) Φ F Ф-tilde, produces: A joint MCMC fit of DESI DR1 BAO + Pantheon+ SH0ES + Planck distance priors yielding w0 = -0. 866+0. 069-0. 067, wa = -0. 564+0. 295-0. 312, Δχ2 = -6. 4 vs ΛCDM, non-phantom thawing preferred at 2. 1σ. A canonical Klein-Gordon FLRW solution that reproduces (w0, wa) = (-0. 904, -0. 160). An integrated CMB birefringence β = cW × 6. 92°, matching the Eskilt-Komatsu PR4 measurement β = 0. 342° ± 0. 094° at 0. 04σ with cW ≃ 0. 0495. A tomographic birefringence prediction βgal (z=1) /βCMB ≃ 0. 79, the key signature versus ultralight-axion alternatives. A growth-of-structure suppression Δ (fσ8) /fσ8 ≃ -5. 4% at z ≈ 0. 5, in the direction of the residual S8 tension. An end of cosmic acceleration at astop = 1. 81, tstop - t0 = 11. 84 Gyr. A complete catalog of 17 multi-channel signatures (cosmic birefringence tomography, anisotropic β, GW chirality, polarized GW background, exact cT = c, pulsar dipolar radiation bound M* > 1012 GeV, fσ8 tomography, Δα/α structural bound cF < 5 × 10-4cW, null ˙G/G, leptophilic electron EDM de ≃ 3. 3 × 10-40 e cm, mass-varying neutrinos, end of acceleration, primordial magnetogenesis, residual lepton/baryon ratio, chiral BH hair).
