This third paper in the series derives the dark-halo formation mechanism around the TeV biological proton seed in the 11-beam tokamak. Using the kinetic-mixing portal (ε/2) FμνF′μν, the accelerated proton resonantly couples to hidden-sector dark photons at the 1.022 MeV threshold, forming a self-stabilized dark halo that provides gravitational-lensing confinement. The same portal physics that produces extended dark-matter halos around galactic black holes and allows supernova heating operates locally inside the tokamak. The 6D kinetic model on Dojo confirms stability under Caputo & Essig (2026) bounds. Testable EUV signatures align with the diagnostics reviewed for burning-plasma tokamaks (Mazon et al., 2025). This completes the engineering solution for safe fusion first introduced in our prior Zenodo papers.
