catalog/detail.go held the two hardest ladders in the codebase: subtitles
resolved across four levels by hand, audio across three, each partially
overriding the last through Has* flags. Both now call the canonical
resolver, so the precedence lives in the manifest and this file cannot
disagree with the contract about which override wins. Adding a scope is a
manifest change rather than another branch here.
The subtitle track signature stays on its specialized table — it identifies
a concrete track rather than expressing a preference, so it is not a
setting.
Resolution keeps the memoization the old lookups had: the audio resolver
still reads once per profile and once per library rather than once per
file, which is what kept a many-track audiobook detail page fast. The test
that guards it now counts resolver reads instead of GetProfile calls, since
the guarantee is about scaling with file count rather than about which
method does the reading.
Four tests seeded the profile column directly. That column is a migration
source now, not a read path, so they seed the canonical value instead —
they were passing against storage nothing reads.
