  title: Dolby OptiView Tear Down a Channel
  summary: Stop a channel, poll until it is fully stopped, then delete it.
  description: >-
    Cleanly decommissions a THEOlive channel. The workflow stops the channel,
    poll-loops the channel until its documented status settles on stopped (so
    no engines are still running), and only then deletes it. Shutdown is
    asynchronous — the channel passes through the stopping state — so the poll
    loop mirrors the async media-job pattern and guards the destructive delete.
    Every step inlines its Authorization header so the flow can be read and
    executed without opening the underlying OpenAPI description.
