3meshd's CUDA: `CUDA_MODULE_LOADING=EAGER` (refusing anything else), the per-machine libcuda override (`--cuda-lib` / `MESH_CUDA_LIB`, re-exec with `LD_LIBRARY_PATH`, checked in `/proc/self/maps`), device 0 with a primary or green context, the per-block limits and register caps of multi-warp nodes, the pinned mailbox (`cuMemHostRegister` DEVICEMAP), cubin modules with their launch shape, scratch memory zeroed on a stream of its own, module globals, occupancy, streams, launches, queries and unloads.
