"""Regression guard for ``gpgpu-sim/setup.sh`` clone-source policy.
The script must default to the upstream URL and use a local mirror only via
the explicit ``GPGPUSIM_CLONE_SOURCE`` environment variable; no personal host
path may be hardcoded. These checks are static (plus ``bash -n``/``--help``)
so they need neither a network nor a GPGPU-Sim checkout.
