  title: Dolby OptiView Inspect an Engine's Last Run
  summary: Pick an engine on a channel, fetch its most recent run, then list its full run history.
  description: >-
    Drills into the run history of a single transcoding engine. The workflow
    lists the engines on a channel, selects the first one, fetches that engine's
    most recent run (start, stop, and configuration), and then lists the engine's
    complete run history. The three read operations chain on the engine id so a
    single pass yields both the latest run and the full timeline. Every step
    inlines its Authorization header so the flow can be read and executed without
    opening the underlying OpenAPI description.
