+"""Continuous autonomous activity for the field agents that don't drive a
+data-movement loop of their own (Lakehouse Ops, Hadoop Ranger, Infra Sentinel,
+Network Watcher).
+
+Every tick the loop runs ONE real, lightweight probe for the next agent in the
+rotation and streams the exact command + result into that agent's terminal, so
+the operator can always see what each agent is doing in the background instead
+of an idle prompt. All probes hit live endpoints (Trino, WebHDFS JMX, YARN,
+Dockhand, VLAN hosts) and are individually guarded so a single failure never
+breaks the loop.
