The `Shows` flip landed today (one field, proven in the server's own
`LibraryOptions` answer), so the posture table no longer calls it a silent file
index and `Music`/`Collections` are named as the remaining ones.
Two corrections the same day's measurements force:
- The per-library `POST /Items/{id}/Refresh` answered `204` and queued nothing
both before the flip and after it — zero journal lines for ten minutes, and
`Scan Media Library` kept `LastTaskResult=None, EndTimeUtc=None`, the never-run
signature. The provider switch was never the reason that door is dead; only
`POST /Library/Refresh` runs (204, then `Running` inside 15 s at 33 % CPU), and
it walks every library, so a library-scoped pass has no door on this build.
That paragraph also records the null-pair read that separates "never ran" from
"just finished", and that query+body on the same call answers `400` with an
empty body whatever the values.
- The key law: a plugin owns its own config file under its own
`<PluginConfiguration>` root and omits null settings, so TVDB's `<ApiKey>`
element never existed and `install` refused — which is what `MISSING key` had
been reporting since October. PR #121 fixes the writer.
The `Shows` art census replaces speculation with the split that matters: 2,908 of
3,558 series+season carry a primary, 624 have no provider id, 26 have an id and no
poster. A `Download` campaign over them took 20 s and downloaded nothing, which is
the measurement that says identification is the only lever left.
