  "abstract": "We study flavor-violating decays of the SM-like Higgs boson and rare top decays in the Type 1B realization of the flavorful two-Higgs-doublet model with a twist, focusing on $h\\to sb$, $h\\to db$, $h\\to uc$, $h\\toμτ$, $h\\to eτ$, $h\\to eμ$, $t\\to ch$, and $t\\to uh$. We present the relevant amplitude and branching-ratio formulae, include one-loop vertex corrections, and impose constraints from Higgs signal-strength measurements, electroweak precision tests, meson mixing, $B\\to X_sγ$, direct HFV searches and CLFV constraints, including $μ-e$ conversion. The surviving parameter space favors $\\mathrm{BR}(h\\to sb)\\gg\\mathrm{BR}(h\\to db)$, $\\mathrm{BR}(t\\to ch)\\gg\\mathrm{BR}(t\\to uh)$, and $\\mathrm{BR}(h\\toμτ)\\gg\\mathrm{BR}(h\\to eτ)\\sim\\mathrm{BR}(h\\to eμ)$ in the lepton sector. One-loop effects usually preserve these hierarchies, but can modify individual channels through different mechanisms: sizable destructive tree--loop interference can reduce $h\\to sb$ enough to yield rare $\\mathrm{BR}_{\\mathrm{1L}}(h\\to db)>\\mathrm{BR}_{\\mathrm{1L}}(h\\to sb)$ points, whereas the large relative corrections found in rare top decays mainly reflect strong SM-like alignment suppressing the tree-level amplitudes.",
