+# This unit was originally deployed on port 8003 as a shadow. After validation,
+# it was promoted to production on port 8002 (t_cd0d5388). The --port value
+# above is the authoritative value; the port 8003 references below are historical.
+# Production is now llama-server-router (this unit); llama-server-qwen is the rollback target.
