applyAudioTagFallbacks captured the ffprobe genre atom verbatim into
media_items.genre — no splitting, no shelf resolution, no cap. That raw
capture is what fed 100+-char Audible category blobs into the column
(the 2026-10 Crusader import/update failures).
The ABS sidecar path already has the correct doctrine (ab2a5568): a known
lexicon shelf wins the genre column, everything else is tags-only. Give
the tag fallback the same treatment — splitGenreCandidates +
pickSmartGenre for the column, split candidates appended to tags
(NormalizeTags dedups). Demoted genres like "Audiobook" stop masquerading
as a shelf, and an unknown blob can no longer manufacture an overflowing
value at all.
Fixtures pin the new behavior: the real 111-char Crusader blob stays out
of the column entirely and lands as six separate tags; a shelf-carrying
blob still wins the column; the previously-pinned verbatim "Audiobook"
expectation is updated to the demoted (tags-only) contract.
