The Fix Loop is the part I'd actually use. With auto-subtitles most of the time goes into scanning lines that were already fine, so a queue of only the doubtful moments makes a lot of sense. How do you decide what gets flagged: low word-level confidence from the speech model, or a second pass that checks whether the sentence reads sensibly? In my experience names and product terms are where auto-captions break most, so a small custom glossary that also feeds the flagging would be a nice addition.
