+# QUOTING / COMMAND PASSING
+#
+# Passing commands as positional arguments ($*) is fragile when the command
+# string itself contains double quotes, e.g.:
+#
+#   bash run-amd-test.sh "export FLAGS="value" && pytest -m "not slow""
+#
+# The outer shell resolves the nested quotes *before* this script runs, so
+# the script receives mangled input it cannot fully recover.
+#
+# Preferred: pass commands via the VLLM_TEST_COMMANDS environment variable:
+#
+#   export VLLM_TEST_COMMANDS='export FLAGS="value" && pytest -m "not slow"'
+#   bash run-amd-test.sh
+#
+# Single-quoted assignment preserves all inner double quotes verbatim.
+# The $* path is kept for backward compatibility but callers should migrate.

+# Pytest marker/keyword re-quoting

+#
+# pytest then interprets "cpu_test" as a file path, not part of the marker.
