The scan was only doing the header-based quality gate (mutagen) — fast but
shallow. The download/import pipeline ALSO runs detect_broken_audio first,
which uses ffmpeg to actually DECODE the file (astats truncation check +
silencedetect) to verify the REAL audio, not just the metadata. That's the
whole point of unifying onto the download quality pipeline.
- Each file now runs both stages: (1) ffmpeg AudioGuard (detect_broken_audio),
(2) header quality gate (probe_audio_quality + quality_meets_profile).
A finding is created for broken/incomplete audio OR below-profile quality,
with quality_issue + broken_audio_reason in details and a 'warning' severity
for broken audio vs 'info' for below-profile.
- New setting deep_audio_verify (default True) toggles the ffmpeg decode pass;
off = fast header-only. Slower full scan is expected — it decodes every file.
