Session and queue statuses

State	Meaning	User action
Queued	The request is waiting; a queue position can be shown when returned	Wait, or cancel if the control is available
Rejected	The request did not enter or continue execution	Read the returned message and retry only when appropriate
Canceled	The queued or streaming request was canceled	Submit a new request if needed
Streaming	Response events are still arriving	Wait or use Cancel
Completed	The response reached a terminal success state	Review the answer and optional evidence
Failed or interrupted	Execution or transport ended with an error	Use the visible retry/recovery path; there is no universal Resume button

Queue state belongs to a request, not to the existence of the Session itself.
