QFT4D.SPERT.02 — a concrete Epstein-Glaser order-2 (one-loop) quartic renormalization, taking the v269 S_pert skeleton from 'exists' to an actual EG number (no path integral). [E] T_1=:L_int: needs no extension, the first extension is T_2; [E] the massless propagator has scaling degree sd=2 in d=4, the one-loop bubble (two propagators) has sd=4=d so the UV singular order omega=sd-d=0; [E] omega=0 => exactly one logarithmic local counterterm (C(omega+d,d)=1, renormalizable, no infinite tower); [E] the loop factor Omega_3/(2(2pi)^4)=1/(16 pi^2) exactly — the same factor that normalises the spectral-action a_4 geometric quartic; [C] the phi^4 one-loop beta = 3 lambda^2/(16 pi^2) (symmetry factor 3 = s,t,u channels), EG initial condition lambda_Phi(UV)=1/(16 pi^2); [O] order-2/one-loop only — the all-order EG construction and the nonperturbative measure QG.AMB.01 stay open. Turns the skeleton into a concrete one-loop number.
