MEON-R2 v1.21/v125 Consolidated Framework: Effective Reservoir Closure, Baryonic Torsion Activation, and Conditional Occam Assessment Relative to ΛCDM

We present the MEON-R2 v1.21/v125 consolidated framework as an effective numerical and theoretical test construction combining R²/reservoir closure, an early-universe activation switch, spin/torsion anchoring, and the v125 baryonic torsion-activation scale. The v125 extension introduces a baryonic activation relation r_s(Mbar) = r_0 (Mbar/M_0)^β with β ≈ 0.3, incorporated through the additional effective term Tbar/tors{μν}(r_s(M{ bar})) and source contribution Sbar(r,Mbar). In the v1.21 combination test, all 18 internal numerical gates pass, including reservoir closure, balanced dark-sector bookkeeping, stable effective torsion evolution, externally anchored spin/torsion proxies, and CMB-compatible equality within the embedded comparison data. The preferred effective comparison yields Δχ^2=0 relative to the ΛCDM baseline in the included CMB test data. Under the conditional closure scenario in which the reservoir/baryonic structure replaces one effective free parameter, the framework shows an Occam advantage with Δ{ AIC}=-2.0 and Δ{ BIC}=-8.58. Under a harsher parameter count in which all R² hyperparameters are treated as free, the model is instead penalized. These results should therefore be interpreted conservatively: MEON-R2 v1.21/v125 demonstrates internal consistency and a conditional Occam advantage in the tested effective CMB-compatible limit, but it does not constitute a final disproof of ΛCDM. Remaining requirements include a full covariant action derivation, official Planck high-/lensing likelihood evaluation, and complete MCMC-based parameter inference.
