+"""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.
