Restructure TV browsing into show detail → seasons → season episodes → player, like
the Plex web app.
Backend: /show/{rk} now returns a rich show page — hero meta (rating/content_rating/
genres/studio + live IMDb), live Cast & Crew, Related shows (Plex 'related', mapped to
our mirrored shows so they're openable), and per-season cards with an aggregate
watch-state + on-deck episode, plus show-level resume (on-deck)/first(play-from-start)/
status rollup. New PlexClient.related(). New bulk-state endpoints POST /show/{rk}/state
and /season/{rk}/state mark every episode watched/unwatched for the user and mirror
each change to a linked Plex account in the background (best-effort, checked once).
Frontend: PlexShowView reworked into the show detail page (hero + Resume/Play-from-start/
Mark-show-watched/Add-to-playlist/[admin]Add-to-collection + season card grid + cast +
related strips); new PlexSeasonView season subpage (hero + Resume/Play/Mark-season/
Add-season-to-playlist + landscape episode grid). Both read the one cached ['plex-show']
payload (season page picks its season out of it — instant, no extra fetch). Player queue =
the whole show (from the show page) or the season (from the season page) so prev/next +
auto-advance follow order. New 'season' history subview; Backspace steps back one drill
level (grid←show←season, out of info/playlist) alongside browser/mouse Back. Season-level
'Add to collection' intentionally omitted (Plex collections hold whole shows, not seasons).
i18n plex.series.* (en/hu/de).
Completes the two-way watch-state sync with two scheduler jobs:
- plex_watch_sync (default 30m): pull recent Plex-side changes (watch history + on-deck, filtered
to the owner account) into Siftlode under last-write-wins (_pull_apply + a _same_state ping-pong
guard + skew tolerance), then re-push any still-unsynced local states.
- plex_watch_reconcile (default daily): full section rescan; uses synced_to_plex to settle what the
incremental feed can't — notably propagating a Plex-side un-watch (clear a previously-mirrored row
Plex no longer has) — while re-pushing never-synced local states and never touching hidden
(Siftlode-only) rows. Union-preserving.
PlexClient gains accounts/watch_history/on_deck; _scan_plex_states is factored out and shared with
the one-time import. Owner accountID is resolved once and cached on the link. Both jobs are
registered in the scheduler (pause-skip, activity tracking, run-now, admin-tunable intervals) with
trilingual (HU/EN/DE) labels + descriptions. New config default plex_watch_reconcile_interval_min.
Verified live against the real Plex server: read feeds, last-write-wins, dirty re-push, the
incremental job end-to-end, and a full reconcile that cleared exactly the one un-watched item with
zero collateral across 17976 scanned.
Mirror watched/unwatched/resume from Siftlode to a linked (owner) Plex account.
- PlexClient: scrobble / unscrobble / set_timeline (/:/scrobble, /:/unscrobble, /:/timeline).
- watch_sync: link_for_push() gates on owner + sync_enabled + initial_import_done; best-effort
push_state_to_plex() runs as a background task with its own session, never raises (Plex being
down must not break the user's action), and flips synced_to_plex on success so Phase C's pull
won't bounce it back.
- item_state / item_progress schedule the push: watched/unwatched immediately, resume only on a
"final" checkpoint (pause / pagehide / unmount) — not every 10s tick — so one watch doesn't spray
/:/timeline at the server. `hidden` is Siftlode-only and never touches Plex.
- Frontend: plexProgress / plexProgressBeacon carry a `final` flag; the periodic checkpoint is
non-final, pause/pagehide/leaving the player are final.
Verified live against the real Plex server (scrobble/unscrobble/timeline round-trip + restore;
link gating; synced_to_plex flip).
Admins can curate Plex collections from a movie's info page ("Collections"
button → PlexCollectionEditor dialog): create a collection (seeded with the
movie), add/remove the movie to/from editable collections, delete a collection,
and "take over" an existing plain Plex collection (mark it editable). All writes
go to Plex (POST/PUT/DELETE via new PlexClient methods) and are reflected on
every client; a targeted single-collection re-sync (sync.resync_collection /
delete_collection_local) updates the local mirror without the full ~4-min sync.
Gating (per the design decisions): editing is ADMIN-ONLY (collections are shared
library-wide); only plain manual collections are editable — smart + external
auto-lists (IMDb/TMDb/…) are always read-only (can_edit = editable && !smart &&
source=="collection"). New admin endpoints under /api/plex/collections
(create/items add+remove/rename/delete/editable). Verified end-to-end incl. the
live Plex write API (create/add/rename/remove/delete all 200, self-cleaned) and
the editor UI (create + delete with confirm) on localdev.
Selecting a subtitle restarted the HLS session with `-map 0:s:{ord}`, assuming an
EMBEDDED stream. Films whose subs are external sidecar .srt files (Plex reports
them, but they aren't in the mkv) matched no stream; the master-playlist's
declared subtitle group then made ffmpeg fail → "Playback couldn't start".
Subtitles now go through a new GET /api/plex/subtitle/{rk}/{ord} → text/vtt
(external subs fetched from Plex via the stream key + SRT→VTT; embedded text subs
extracted with ffmpeg; image subs → 415), served as native <video><track> that
the browser overlays. So choosing/switching a subtitle is instant with NO session
restart, and stream.py drops all subtitle muxing (`-sn`, no master playlist).
Image-based subs (PGS/VobSub) are marked text=false and hidden in the picker.
Verified on prod's Nymphomaniac Vol. II: HU sidecar → 1693 WebVTT cues, no crash.
Posters/art were proxied at full resolution (many 1-7MB, some 9.5MB) into ≤176px
grid/info cells — heavy to fetch + decode, so fast scrolling lagged 1-2s even
with a warm cache (the cache removed the Plex round-trip, not the image weight).
Now PlexClient.image_bytes optionally hits Plex's /photo/:/transcode to resize
server-side; the /image endpoint requests thumb=400x600, art=1280x720 and keys
the cache by width (old full-size files orphaned, re-cached small). Measured:
a poster 5.5MB->50KB, art 8.1MB->137KB, at 400x600 (crisp on 2x DPR). Grid
scroll is near-instant and the disk cache shrinks ~8x.
Backend (migration 0047_plex_collections): a plex_collections table mirrors every Plex
collection (card metadata + smart flag + an editable flag reserved for Phase 2); membership
is stored as GIN-indexed collection_keys on member movies (plex_items) and shows (plex_shows).
The background sync (plex_sync) now fetches each library's collections + their children and
rebuilds membership — so ALL reads are local (Plex's dual-language collection queries are slow;
this trades a ~4-min background sync for instant reads). New /api/plex/collections endpoint;
/browse gains a combinable filter; item_detail returns the movie's collection
'strips' (sibling titles as playable cards, smallest/most-specific collection first) — all pure
local lookups.
Frontend: PlexSidebar gains a searchable Collection picker + an active-collection chip;
PlexInfo renders the collection strips (playable posters + 'Browse collection' → sets the
filter); the collection is part of PlexFilters (persisted). i18n en/hu/de.
Phase 2 (create/edit collections with write-back to Plex) is separate.
