The CDUFD framework predicts that fermion masses follow the critical scaling mf ^ (nf-14), where nf is determined by SO (8) quantum numbers. Using the SO (8) weight formula we compute theoretical critical orders for all Standard Model fermions. Comparison with experimental masses reveals systematic deviations: nₑ = -0. 345, n_ = -0. 685, n_ = +0. 345, i. e. the striking integer ratio nₑ: n_: n_ = -1: -2: +1. This pattern cannot be explained by a single critical point. We propose that it arises from critical lag during the electroweak phase transition: different generations (associated with the three inequivalent SO (8) representations) possess distinct relaxation rates relative to the spacetime relaxation rate. Using a simplified Langevin model we show that the observed nf implies relative relaxation rates ₑ: _: _ 0. 655: 0. 315: 1. 345. The model requires a second critical point in the neutrino sector (nc¹3. 5), which naturally explains the smallness of neutrino masses via the seesaw mechanism. Using the unified scaling law and NuFIT 6. 0 (2024) oscillation data, we predict the flavour‑eigenstate mass ratio m䂰: m_: m_=1: 1. 15: 1. 28, i. e. m䂰/m_=1. 150. 04, testable at JUNO. This work interprets fermion masses as direct evidence of non‑equilibrium critical evolution in the early universe. V2. 0 upgrades the generation assignment from a triality-based postulate to a dynamical derivation: the vector representation couples directly to the spacetime metric, the spinor representations couple through the spin connection, yielding 8v>8R>8L8v>8R>8L as the mass ordering. The integer ratio +1: −2: −1+1: −2: −1 is theoretically predicted, not post-hoc fitted; experiment agrees to within 8%.
