The old Quality Scanner tool judged quality by file EXTENSION only (a 128k and a
320k MP3 looked identical), ignored the bitrate-based quality profile, used min()
of enabled tiers so the default profile flagged the ENTIRE non-lossless library,
and auto-dumped every match into the wishlist with no review.
This new repair job does it properly:
- meets_preferred_quality(): pure, bitrate-AWARE decision honoring every enabled
quality bucket (320 MP3 passes a FLAC+320+256 profile; 128 MP3 doesn't). Floor
is the worst enabled bucket, not the best.
- scans watchlist artists or whole library, finds below-quality tracks, matches a
better version at scan time (reusing the existing tested match helpers), emits a
FINDING showing the match + confidence. Off by default; nothing auto-queued.
- _fix_quality_upgrade apply handler adds the matched track WITH album context to
the wishlist — the user-approved version of what the old tool did silently.
- Transcode/fake-lossless detection intentionally left to the existing Fake
Lossless Detector job.
12 seam tests incl. a regression pinning the default-profile flooding bug. The old
tool is still in place; removing it + rewiring its automation action is the next step.
