The completeness + duration guards used MusicBrainz's target.track_count /
total_duration_s, but MB picks an arbitrary releases[0] that is often a
deluxe/expanded edition with more tracks (and runtime) than the standard album a
source legitimately delivers. So complete standard-edition downloads were falsely
rejected — The Script 'No Sound Without Silence' (11 vs MB 12) as 'incomplete
download', Skillet 'Unleashed' (12 vs MB's 20-track deluxe) as 'too short'.
Now completeness is judged against the chosen source's own track count
(winner.track_count): a truncated download (fewer files than the source promised)
still fails, and the duration expectation is scaled to the delivered edition's
size. A separate 'implausibly small vs MB' guard (source has <= half MB's tracks)
still rejects a lone-track 'full album' video. Genuine partials (e.g. John Mayer,
a Qobuz track failing mid-download) still correctly fail.
