  "abstract": "In this work, we systematically investigate top-quark flavor-changing neutral-current decays, charged-lepton flavor-violating processes, and coherent $μ-e$ conversion in the CP-conserving generational three-Higgs-doublet model (G3HDM), including the relevant tree-level and one-loop contributions. The 4839-point sample passes conservative sufficient vacuum-stability conditions, necessary perturbative-unitarity preselection cuts, Higgs-mass and signal-strength constraints, electroweak precision data, the UTfit 2025 neutral-meson-mixing ranges, $\\overline{B}\\to X_sγ$, and $B_s\\toμ^+μ^-$. In the scanned region, $\\mathrm{Br}(t\\to c h_1)\\leq 1.04\\times10^{-5}$ and $\\mathrm{Br}(h_1\\toμτ)\\leq 4.83\\times10^{-4}$, while the maximal conversion rates are $\\mathrm{CR}(μ\\mathrm{Al}\\to e\\mathrm{Al})\\approx 4.95\\times10^{-15}$ and $\\mathrm{CR}(μ\\mathrm{Au}\\to e\\mathrm{Au})\\approx 1.05\\times10^{-14}$. The dominant collider signals are mainly driven by tree-level flavor-changing neutral-Higgs couplings, which determine the relative strengths of these processes and induce the pronounced enhancement of $t\\to c h_1$ and $h_1\\toμτ$. Meanwhile, the upper range of the predicted $μ-e$ conversion rate in aluminum lies within the sensitivity reach of next-generation $μ-e$ conversion experiments.",
