Source bundle pages 134–138. The paper cover establishes 2022; the attachment filename uses 2021. All times in the <kaon> calculations are <proper times>, unless a laboratory conversion is explicitly made. The <CP symmetry> approximation is used where the paper identifies the physical short- and long-lived states with <kaon CP eigenstates>.
