TMD: The Particle Layer of the System (Particle Physics — Part 2)

This work is the second part of the TMD series. While Part 1 demonstrated that stable particles arise as closed triadic structures, Part 2 describes the particle layer of the system itself. The text introduces four types of modules that appear in classical physics as baryons, mesons, quarks and neutrinos. In TMD, these are not independent objects but manifestations of a single orientational mechanism based on triads, thresholds, jumps and cascades. The work is intentionally minimal. It presents the conceptual structure without the computational apparatus. The equations of the deep layers — which determine masses, decay times and shielding — will be published separately. This document is part of an ongoing effort to build a coherent ontological framework for particle physics based on a single generative principle.
