The 12h retry budget hands a bare failure to the periodic stale-absent
sweep, which is what makes the resulting absent row recoverable. Media
files are deliberately excluded from that sweep -- they resolve embedded
only, at scan or on view -- so exhausting the budget on a transient read
error recorded a "this track has no cover" verdict that nothing would
ever revisit.
Settle absent only for kinds a recheck job covers. Without a row the
track stays unresolved, so the next view re-enqueues it.
