The Holographic Fiber Theory (HFT) substrate is a discrete trivalent cell complex with Hopf-bundle topology S³ S² (with S¹ fibers), with B₂-braided edges and B₃-braided vertices; its 5-DOF phase space Q = R^+ S² S¹ ₓ₀₍ S¹ ₇₎₅ emerges macroscopically as R³ space, spin/helicity, and energy. A single global Z₂ symmetry-breaking event -- the chirality lock -- fixes the handedness of every B₂ framing, converting the parity-symmetric substrate into the chirality-locked substrate. The locked mesh's topology forward-derives two electroweak coupling constants ²W = 30/128 and ^-1 = 137, tied by a closed-form relation ²W (Q) = 1/4 - 2/^-1 (Q) valid for 0 Q MZ. Based on these coupling constants, the same topology forward-derives the lightest Majorana neutrino mass m䃑 1. 8 meV as a sharp falsifiable target, and the CMB temperature T₂₌₁ 2. 725 K from the substrate's minimal-fluctuation thermal floor.
