-- The library's albums go on the wanted list as held, once (M502 #5567,
-- operator 2026-10-10). After that the list is the truth: an album taken
-- off it stays off, and one dropped into the library folder by hand is not
-- added. Re-acquisition fetches back only albums on the list.
--
--   wants.reason                 library: on the list because the library
--                                held it when the list began.
--   acquisition_settings         when the one-time listing began (its cutoff:
--                                albums added later are not listed), when it
--                                finished, and how many albums it could not
--                                list because nothing names them to
--                                MusicBrainz.
--
-- The listing itself runs in the wanted worker after boot, not here: it may
-- have to ask MusicBrainz for each album's release group.
