12/// and is ready to receive commands. Includes timing data for boot
13/// performance measurement.

30/// Payload for `core.relay.client.disconnected` messages.
31///
32/// Sent by the host relay when one SDK client socket disconnects. The
33/// guest agent uses the assigned correlation ID range to clean up resources
34/// owned by that client, such as open filesystem handles.
