This diagnostic test uncovers the radial acceleration relation in synthetic galaxies, indicating its emergence at a population level.
We execute the population-level RAR test defined in Paper X. Using 315 synthetic galaxies (15 masses x 7 mass-to-light ratios x 3 gas fractions) with exponential disk profiles, we compute g_obs vs g_bar for B' and B'' and extract the effective knee acceleration a_eff^knee. The pipeline tests whether the SPARC best-fit parameters (beta=2.676, X_*=5.46e-57) reproduce the observed RAR scale a_0~1.2e-10 m/s^2 as a population-level emergent phenomenon. Reproducible code included.
