Description
The investigation of $B$-meson decays into charmed and charmless hadronic final states is a keystone of the Belle II program. It offers theoretically reliable and experimentally precise constraints on CKM unitarity, it is sensitive to effects from non-SM physics, and it furthers knowledge about uncharted $b \to c$ hadronic transitions. Recent results on branching ratios and direct CP-violating asymmetries of $B \to K \pi$ decays are presented that lead to world-leading tests of the SM based on the $K \pi$ isospin sum rule. First observations of new $B \to D^{(*)}KK_S$ decays and new results from combined analyses of Belle and Belle II data to determine the CKM angle $\phi_3$ (or $\gamma$) are also presented.
