+# Throwaway: runs the integration suite 10x against sdkdev to check PR #167's de-flaking.
+# Delete this branch when done. Never merged to main.
+#
+# max-parallel MUST stay 1: TaskClientTests @AfterAll unregisters fixed-name workflow defs
+# (complex_wf, sub_wf_1, sub_wf_2, wait_signal_test) on the SHARED sdkdev server, so
+# concurrent runs would delete each other's definitions mid-test and fail for fake reasons.
