>
> {{StreamSession}} contains an implicit state machine, but we have no
> verification of the safety of the transitions between states. For example, we
> have no checks to ensure we cannot leave the final states (COMPLETED, FAILED).
> I propose we add some program logic in {{StreamSession}}, tests, and
> documentation to ensure the correctness of the state transitions.
