IV.R242 — Part~II in perspective

Part II achieves concrete predictive power: the ten-link derivation chain from axioms K0-K6 through Epstein zeta eigenvalues, the lemniscate spectral distance sqrt(3) = |1 - omega|, and the triple holonomy correction pi^3 alpha^2 yields R = m_n/m_e to 0.025 ppm with zero free parameters.
