aiter, Primus-Turbo, triton and uccl were full-history cloned, and their pinned submodules (e.g. composable_kernel) were fetched without --depth, turning a single git clone into 30-45min on a slow link. Use partial clone (--filter=blob:none) for repos checked out by SHA, and shallow clone/submodule update for repos/submodules pinned to a tag or exact SHA.
