Appendix C: Unified Triple-AI Derivation of the GIGL/GCT/MDD Cosmic Triplet and the GIGL Foundation Equation (Summary Version)

This Appendix consolidates the independent mathematical reasoning produced by three state-of-the-art AI reasoning engines—ChatGPT, Grok, and Gemini—each deriving the same three cosmic structural constants from the GIGL (Geometric Invariant Grid Layer), GCT (Geometric Critical Threshold) and MDD (Minimal Dissipation Dynamics) framework, without being shown each other’s work. All three systems independently reproduced: εGCT = 0.00727, ηfold = 0.275, Ycosmic = 0.04125. These constants are shown to be not empirical guesses but a single inseparable triplet generated by the geometry of a 16-node invariant substrate underlying spacetime.
