We identify the missing mechanism as an Ising blockade: configuration-dependent diagonal interactions dynamically detune neighboring spins, so that the transport bottleneck is set by the correlated pair-detuning $\\epsilon_{ij}$ rather than by the single-spin linewidth. The resonant fraction is suppressed linearly with the Ising broadening $\\Gamma_{\\mathrm{Ising}}$ -- in contrast to the quadratic suppression of conventional relaxation-time approximations.
