We dress FKM's IdylliQ model with in-medium potentials, constrained by hypernuclear data and neutrino-induced hyperon FSI, and find: (i) the dressed onset, $\\muB^{\\rm onset}=(2M_Y{-}M_N)+2U_Y-\\UN$, carries $U_Y$ at weight 2, with $dn_{\\rm onset}/dU_Y\\simeq0.3\\,\\nz$ per $10\\MeV$, twice the leverage.
