minstrel/internal/db/migrations/0071_reopen_false_reacquisition_completions.up.sql

-- Before: the reconciler completed album and track requests as soon as the
-- album had any track on disk. Re-acquisition targets albums with only SOME
-- tracks missing, so those requests completed the moment Lidarr accepted the
-- add, with nothing downloaded.
--
-- Reopen every completed album/track request whose matched album does not meet
-- the corrected test: a track
-- that arrived after the request, or no track that was already missing at the
-- request still missing. The reconciler then judges them again; the Lidarr add
-- stays confirmed, so nothing is re-sent. Requests that genuinely completed
-- meet the test and are left alone.
