The question we want to analyze is described by Branco, Lavoura and Silva:

There is no other particle with equal mass. Therefore, K_L must
be its own antiparticle. It decays both to Pi⁺e⁻Nu_e and to the C-conjugate
mode Pi⁻e⁺Nu_e. However, it decays slightly less often
to the first than to the second mode. This fact unequivocally
establishes both C violation and CP violation.

There is an unstated assumption in their statement: the decays of the kaon are
internal (independent of the background) and acausal (they have no cause). These
assumptions come from standard quantum mechanics.
We show that there is a cause for their decay and there is neither C violation
nor CP violation in the decays of the kaon. The asymmetry in the decays is due to
the asymmetry of the background, not an inherent difference.
