Completeness/duration verification was applied only to the first candidate that downloaded successfully; if that copy was incomplete or too short the whole job failed, even when a later-ranked source had a complete copy (e.g. John Mayer 'The Search for Everything' — Qobuz reliably fails one hi-res track, so it never fell back to the deluxe edition or Soulseek). Extract the checks into a pure _download_problem() and run it INSIDE the download loop: a candidate that downloads but fails verification now falls through to the next-ranked source, and the job only fails (needs_attention) when every candidate is incomplete — reporting the last shortfall reason.
