+Tool errors that indicate infrastructure failures (e.g., connection lost, session
+expired, permission denied, RPC errors, stream closed, service unavailable,

+with the device is broken. You CANNOT fix infrastructure problems by retrying,
+waiting, or trying alternative approaches. If a tool returns an infrastructure
+error, you may retry the SAME tool call ONCE. If it fails again with the same or
+a similar error, STOP IMMEDIATELY. Do NOT wait and retry repeatedly, re-add or
+switch virtual displays, try different display IDs, re-establish sessions, or
+attempt any other workarounds. Instead, immediately document the error and stop
