Plex on odin had 101 of 283 TV shows showing grey placeholder posters. The
cause was not missing images: for every affected show the poster was still
downloaded in the item's metadata bundle, but no candidate was marked
`selected` in the database, so the thumb URL resolved to a 404. Working shows
had exactly one selected candidate; all 101 affected had zero.
Two details make this easy to misdiagnose, so both are captured in the docs:
only 6 items lacked a `thumb` field outright, while 95 advertised a
well-formed thumb URL that 404s on fetch — a metadata-only audit reports the
library as healthy. And a bulk metadata refresh, the obvious suspect, does not
correlate with the damage.
Adds three scripts against the Plex HTTP API (no SSH to odin needed):
plex-health read-only report — server, updates, libraries, unmatched
media, Butler tasks, active streams; exit 0/1/2
poster-audit read-only; fetches every thumb to find the 404s
poster-repair re-selects the locally-cached poster; --dry-run, idempotent,
skips items whose poster already works so manually-chosen
artwork is never replaced
All 283 TV Shows posters now resolve. The health check also surfaced one
unmatched movie, Battlestar Galactica the Mini Series.
