Motivated by recent HAL QCD simulations of the $$\phi N$$ interaction in the $$^4S_{3/2}$$ channel and its modification in the $$^2S_{1/2}$$ channel, we develop a first-principles few-body framework that embeds these potentials into configuration-space Faddeev--Yakubovsky equations. We predict bound $$^4_\phi\mathrm{H}$$, $$^4_\phi\mathrm{He}$$, and $$^5_\phi\mathrm{He}$$ nuclei by performing calculations for $$\phi$$-mesic $$\phi NNN$$ and $$\phi NNNN$$ systems. Both spin-dependent and spin-independent $$\phi N$$ interactions are considered, leading to deeply and moderately bound states, respectively. The deeply bound states originate from the strong attraction in the $$^2S_{1/2}$$ $$\phi N$$ channel. Coulomb shifts of the binding energies are evaluated. Our findings provide the binding mechanism and demonstrate the importance of short-range $$\phi N$$ attraction.
