Multi-wavelength MCMC modeling of RCW 38 supports hadronic gamma-ray production with K_ep ≲ 10^{-3} and acceleration efficiency ≳1%, consistent with cosmic-ray composition requirements.
Galactic magnetic field time delays for transient UHECR sources induce a spectral cutoff, composition shift to heavier nuclei, and developing dipole anisotropy over ~100 kyr timescales.
