A Causal Model for Dark Matter: Evidence of a Galactic Scaling Law and the Influence of Baryonic Feedback

(Evidence of Non-Gravitational Dark Matter-Baryon Coupling from a Universal Scaling Law in Dwarf Galaxies "https://zenodo.org/records/17517266") This supplementary document provides comprehensive statistical validation of the DDIC-DM (Chiral Dark Matter with Density-Dependent Interaction) model published in the primary paper (DOI: 10.5281/zenodo.17400541). KEY FINDINGS:- Rigorous Bayesian analysis of 15 independent quantitative convergences- Combined probability P(all convergences by chance) < 10^-12 (less than 1 in trillion)- Posterior probability P(model correct | evidence) > 99.99%- Likelihood ratio ≈ 10^12 (trillion-to-one in favor)- Monte Carlo simulations demonstrate model robustness- Comparison with 47 alternative models in literature- Detailed predictions for June 2026 falsification window This analysis demonstrates that the DDIC-DM model exhibits unprecedented statistical evidence compared to typical speculative models and merits serious experimental verification before the June 2026 critical window when Earth traverses the S1 stellar stream.
