On 2026-10-20 twelve of the 24 slots the resolver emptied were folded by MBID
into the kept copy, so their albums were never wanted back.

Shnabubula's whole album, one 45-minute file, was filed as both Fading Light
and Looking for Answers. Neither slot fits, so wrongSlots had nothing to keep
and held the group. Every copy now goes when each is clearly another song's;
a copy near its slot still holds the group.

20 of the 34 groups left for review had no cached track list for their album:
the catalogue only reads one when the wanted list or the importer needs it.
The resolver now asks catalogue.RefreshReleaseGroup for an album it must
decide and the catalogue has never read, through the shared MusicBrainz pacer,
at most five a pass (hourly). An unreachable MusicBrainz stops the pass's
fetching; a group read and found empty is not asked about again.

- songKey drops a dashed version suffix (" - Instrumental Version", " - Radio
Edit", live, remix, mix, acoustic, demo, reprise, rework, VIP), so Andora's
"Goodbye Yesterday - Instrumental Version" is distinct, not a wrong slot.
- wrongSlots accepts several fitting copies when they share one title
(Killjoy twice beside Dreamland): the other slot's copy is removed, and the
doubled song is left for the next sweep to find as a pair the resolver merges.

The operator's library had 536 groups waiting for review, 2026-10-19. A sample
showed most were one recording under two titles on two releases.
- The headline and the Duplicates count leave out cross-release groups, which
the resolver keeps and links: the headline read 3,479 when 536 needed review.
- Any group spanning albums is cross_release and is linked as one song,
whatever its titles say. Nothing is deleted.
- One album, two versions named as such ("Lovesick (Instrumental)") and not
byte-identical: a new class, distinct, dismissed by the resolver.
- One album, one recording under different song titles (mismatch): the
album's cached MusicBrainz track list decides. When exactly one slot's song
is as long as the file and every other slot's song is clearly not, the other
copies are removed and their tracks marked missing, so the reacquisition
sweeper wants the album back. Otherwise the group stays for review.
- The duplicates_found notice moves from the sweep to the resolver: it names
only groups a pass first left for review.
- Resolved automatically lists dismissals and wrong-slot removals beside
merges.
Migration 0094 adds 'distinct' to the class CHECK (rule 36).
