  title: Dolby OptiView Audit Channel Run History
  summary: Resolve a channel, list its engine runs, and pull its transcoding-minutes analytics.
  description: >-
    Produces an operational audit of a THEOlive channel. The workflow confirms
    the channel exists and captures its current status, lists the historical
    engine runs (each run records start, stop and configuration), and finally
    pulls the transcoding-minutes analytics for a reporting window. The three
    read operations chain on the channel id so a single pass yields a complete
    run-and-usage picture. Every step inlines its Authorization header so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
