A read already stored answers ready and starts nothing; every other is queued as its own job, or answers skipped, refused or held (the computer reading it holds it back) with the reason, and the rest still start. job_ids goes to one get_jobs call; each read is stored on its item as its job succeeds, and transcribe_media, speakers, detect_beats and search_footage then return it free. estimate is the cloud minutes started and what is left. A repeat call starts nothing twice.
