Two defects sank Explore's Plex integration. Discover started rejecting
X-Plex-Container-Size=500 with a 400, so the watchlist membership
snapshot never loaded: hearts stayed unknown and toggles dead. The
snapshot now pages at 100, and getWatchlist refetches a rejected page in
chunks of the row fetch's field-proven 25, so the next cap drift degrades
gracefully instead of failing and callers' offset math survives either
way.
Worse, every Plex catalog item reached the library matcher carrying only
its Discover rating key: listings were fetched without includeGuids, so
the lookup rested entirely on exact plex:// guid equality between two
metadata universes (Discover duplicate entries break it, notoriously for
anime), and the title fallback can never confirm a candidate without
external ids to intersect - "Not in your library" for owned titles the
MAL provider matched fine. Discover listings now request Guids, the
detail screen re-runs the matcher when enrichment gains id forms
(generation-guarded so the slower bare lookup cannot overwrite the
richer verdict), the matcher keys its memo by id fingerprint so the poor
form's cached negative cannot answer for the rich one, and the Plex
client stops burning title requests that external-id verification is
guaranteed to reject.
Discover requests are now logged like every other API surface; this bug
shipped blind because they were not.

Explore shelf cards drew a poster, a title and a year. An audit of all six
catalog sources found the rest was lost at two boundaries — the wire-to-DTO
mapping and the DTO-to-CatalogItem mapping — and then simply not drawn: the
grid card fell through every branch of buildMetadataSubtitle to the year-only
case, while the list card used by search already composed certification,
runtime and rating from fields the synthesized MediaItem already held.
Extend CatalogItem with the neutral facts every provider had been dropping:
attributed rating sources, leaderboard ranks that keep their season window,
audience counters that keep their timeframe, broadcast slots, next-episode air
times, server availability and request state, exact release dates, alternate
titles, format, source material, studios, countries, languages, credits, tags,
links, artwork variants, play state, gallery art and background prose. Replace
fetchCast and fetchRelated with one fetchDetail returning the enriched item,
its cast, its recommendations and labelled franchise relations without adding
a request: sources needing two calls keep two and run them concurrently with
isolated failures.
Map those fields in all six sources, widening only field selections that cost
no extra round trip — MAL's fields list, AniList's selection set and a bounded
row cast that lets detail skip its character call, Trakt's guest stars, Seerr's
language parameter and TMDB size ladder, and Plex's includeUserState. Plex hub
artwork widens only on TV, where the spotlight is its only consumer, because it
doubles the payload.
Render them: a rating-first caption and bounded badges on the shelf card,
labelled sections on the detail screen, provider hub styles and result counts
on shelves, and logo, banner and accent art in the TV spotlight.
Verified against live Plex, AniList, Simkl and MAL responses, and on a Pixel 7.
Plex Explore showed only the Watchlist row. `/hubs/sections/watchlist`
answers with placeholder hubs — every entry carries `placeholder: true`,
`size: 0` and no `Metadata` — so `fetchHubs` mapped each one to an empty
page and dropped all of them. That is true no matter what the profile has
watchlisted; the shelves never rendered.
Read `/hubs/sections/home` instead, the section Plex's own web client
renders on its Home > Trending tab, and hydrate each placeholder from its
own key (six at a time). `directory` shelves list browse categories and
`clip` shelves list trailers, neither of which becomes a catalog item, so
they are skipped before spending a request. A shelf that fails degrades to
the ones that succeeded; a pass where every shelf failed still throws.
Discover ignores container offsets on hub keys and truncates with `limit`
instead, so a hub is one page: View All takes the whole shelf in a single
request rather than replaying page one, and hub requests drop `Media` and
`Image` elements the catalog layer never reads.
