Enqueue

Tag 7: the client sends a message to the agent, which starts a loop when none runs and joins the queue when one does; the server opens an enqueue channel on the container’s begin scope and relays exactly one channel response, the fate of the message, when the fate is known.

The client opens this channel to send a message to the agent. A message sent while no loop runs starts one, as its input; a message sent while one runs is placed in its queue. The server opens an enqueue channel on the begin scope of the container’s proxy with the message and relays the fate the proxy answers. What the agent says in reply is the main stream of the scope, as Response states.

• The request. The tag byte 7 followed by the message as JSON. Request states its form.
• The response. Exactly one channel response, sent when the fate of the message is known, however long that takes, and the channel response finish. Response states the sequence.
