// Why a transcription failed, so a batch can decide whether to retry it on a
// different worker. "transport" = the worker/transport was at fault (remote
// unreachable, 5xx) and the audio may still transcribe elsewhere; "transcription"
// = the audio itself failed and retrying on another worker is pointless;
// "no-audio" = the video has no real audio file (a download/source problem, e.g.
// a corrupt-source / failed-extract download), so the batch skips it rather than
// recording a failure and a re-download will let it transcribe later.
//
// In its own module (no deps) so both transcribeOne.ts and the remote client
// (remoteTranscribe.ts) can throw it without an import cycle.
