Our data reveal clear-cut evidence for magnetic heat transport within the IrO$_2$ planes which provides the unique possibility to analyze the thermal occupation and scattering of $J_\\mathrm{eff} = 1/2$ pseudospin excitations. The analysis of the magnetic heat conductivity yields a low-temperature ($T \\lesssim 75$ K) magnetic mean free path $l_\\mathrm{mag} \\sim 32$ nm, consistent with boundary scattering.
