000003888 520__ $$aMeasurements of time dependent CP violation are chief goals of the Belle II physics program.  Comparisons of penguin-dominated $b\to sq\bar{q}$ to tree-dominated $b\to sc\bar{c}$ results allow for stringent tests of CKM unitarity that are sensitive to non-SM physics, but require excellent vertexing capabilities. After presenting recent world-leading results on charm-hadron lifetimes that demonstrate the Belle II vertexing performance, a novel algorithm to identify the flavor of neutral charm mesons that effectively doubles the sample size for many measurements of CP violation and flavor mixing is presented. We report on results on $B^0 \to K^0_S \pi^0$, $B^0 \to  K^0_S K^0_S K^0_S$, and $B^0 \to \phi K^0_S$ decays.
