A discrete, deterministic, reversible model that derives the architecture of the Standard Model and a universal computer from one premise, a single reversible distinction, on a forced hyperbolic mesh of 24-cells. Every result is checked by reproducible open-source experiments, with the absolute masses and couplings left free, exactly as in the Standard Model, and this is offered as exploratory, feasibility-stage work, a potentially interesting direction perhaps worth pursuing rather than a finished theory.
