We have lots of examples of radiators in space (because it’s approximately the only thing that works), and AFAIK micrometeor impacts haven’t been a dealbreaker when you slightly overprovision capacity and have structural redundancy. I don’t expect you’d want to spend too much on shielding, personally.
Not trying to claim Starcloud has a fully coherent plan, ofc.
