  title: Dolby OptiView Stop a Channel and Confirm Idle
  summary: Stop a running channel and poll until it has fully settled in the stopped state.
  description: >-
    Gracefully winds down a live THEOlive channel. The workflow issues the stop
    command, which stops every connected engine, then poll-loops the channel
    until its documented status reaches the stopped terminal state (or error).
    Shutdown is asynchronous — the channel passes through the stopping state
    before reaching stopped — so the poll loop mirrors the async media-job
    pattern. Every step inlines its Authorization header so the flow can be read
    and executed without opening the underlying OpenAPI description.
