- collections: the resync-failed-after-successful-write path now returns 422
(honest "reconcile on next sync" detail), NOT 502. The frontend treats
502/503/504 as gateway-unreachable and raises a sticky offline banner
(api/core.ts RETRIABLE_GATEWAY); the app answered, so a 422 action-error
toast is correct. Removes the false-offline regression the 502 introduced,
and — since 422 isn't retried — the create double-write vector with it.
- tests: make the mutate-then-resync rollback assertion non-vacuous — the
resync stub now flushes a partial local change before raising, so the test
proves db.rollback() actually undoes it; split into a write-failed (422)
case and a resync-failed (422 + reconcile detail + rollback) case.
- New-collection dup hint is now muted-tone with its own nameMaybeTaken copy
(per-library uniqueness means the name may be free here) instead of the red
authoritative nameTaken, which the still-enabled create flow contradicts.
- history: cover the navCounter post-reload collision guard (ensureNavId
advances the counter past a higher persisted sfScroll id).
Round of USER-triggered deep-review fixes (11 CONFIRMED + 1 PLAUSIBLE, all
verified) on the 22-commit branch:
- collections: split the mutate-then-resync error surface. A resync READ that
fails after a successful Plex mutation no longer reports a false 422 "Plex
write failed" + rollback; it returns 502 "sync pending" (the next full sync
reconciles the mirror). New _write_or_pending_error helper; delete is exempt
(no Plex read). Covered by new happy-path / 422-rollback / 502 tests.
- New-collection dup-name guard is now advisory only: existingNames is the
search-scoped, all-library union, but the backend enforces uniqueness PER
library — so it no longer blocks a valid same-name collection in another
library, and the backend 409 is localized to nameTaken.
- member-remove now confirms before the write-through (matches delete-collection).
- add-title / new-collection library search render an error state on request
failure instead of a misleading "No matches".
- history: seed navCounter past the current entry's persisted sfScroll on load
so post-reload ids can't collide with back-stack entries and mis-restore scroll.
- PageScroller: LRU-cap the navId-keyed savedScroll map (was unbounded).
- share isIntrinsicReadOnly between the browse tile and the info page so the
lock/edit affordance can't drift.
Two follow-ups after testing the collection editing against real Plex, which revealed that
Plex CONFLATES same-named collections (two rating_keys resolve to one merged member list) —
a genuine footgun.
- Duplicate-name guard: create and rename now reject (409) a title that already exists in the
target section (case-insensitive), before any Plex write. create() can also derive the
library from the seed item, so the caller needn't know the section key. The create dialogs
surface the 409, and the New-collection panel warns inline before submit.
- A "New collection" button on the Collections browse surface (admin only) opens a panel:
a name field (with the live duplicate check) + a search to pick the FIRST title — Plex can't
create an empty collection, it needs a seed. Creating opens the new collection's detail page
straight away, so you can keep adding titles there. This is the B-route the user wanted,
vs. the only prior path (a movie's "add to collection").
Verified live: the 409 guard (creating an existing name is blocked, no Plex write), and the
full New-collection flow (name + first title → create → lands on the detail page); test
collections created and deleted, real account left clean.
Gate: tsc/lint/knip/prettier clean, 424 vitest; backend ruff clean, 7 collections tests
(+ a duplicate-name-rejection assertion).
Clicking a collection tile now opens a dedicated Collection info page (like the Plex-web
one) instead of just applying it as a filter. New GET /collections/{rk} returns the hero
aggregates (year range, most-restrictive member cert, total runtime) + the members ordered
by release year then title; a new PlexCollectionView renders the hero (art/title/meta/
summary+More) and the member grid, with a Play-all and Shuffle over the playable leaves
(reusing the player's existing queue + auto-advance).
For a non-external, admin-enabled collection the page offers rename / delete / add-title
(a search picker) / remove-item, all through the pre-existing admin endpoints that write
THROUGH to Plex (each edit awaits and re-fetches — no optimism, since a Plex write can 422).
An eligible collection shows "Enable editing" first (the DB editable flag). Read-only ones
(smart / imdb / tmdb / … auto-lists) are marked with a lock on both the info page AND the
browse tile, up front.
New `{ kind: "collection" }` sub-view wired through plexSubUrl (bookmarkable ?v=collection:rk),
PlexBrowse (render branch, Backspace back-nav, tile handler), with a round-trip test.
Verified live: tile→page, hero + chronological members (James Bond 1962→2021, PG-13, 55h),
Play/Shuffle, Enable editing → edit controls + remove-X, the add search (marks already-in
titles "Added"), and the read-only lock on external collections. Real Plex mutations wired
but not executed against the live account.
Gate: tsc/lint/knip/prettier clean, 424 vitest; backend ruff clean, 6 collections tests
(+ a detail-hero/ordering assertion).
The collection browse-tile montage queried only movie members, so show-library
collections (IMDb Popular, TMDb Trending, … in the TV library) rendered as bare colour
tiles. Union the art from PlexShow members as well (a collection lives in one library, so
exactly one side has art); fall back to the collection's own poster, then the colour hash.
Runtime stays movie-only (shows have no single duration).
Verified live: every collection now shows a montage (0 art-less tiles, was ~all the show
collections).
Gate: backend ruff clean, 5 collections tests (+ a show-collection art assertion).
The full-bleed 4-poster collage drowned the on-tile text. Split PosterTile in two: the top
half shows up to 2 montage posters, the bottom half is a solid colour-hash band that carries
the label, so the text is always readable. Genre tiles drop the count (just the label now);
collection tiles show the name on one truncated line plus a sub-line of item count · total
runtime. A group with no art falls back to an all-colour tile.
Backend: `/collections` cards gain `total_runtime_s` (a new `runtime_by_key` grouped sum) and
their montage art is capped at 2. Frontend: PosterTile reworked; a `collectionMeta` helper
builds the count·runtime sub-line via the existing formatRuntime.
Verified live: collection and genre tiles render 2 posters over a readable colour band with
the right sub-lines; colour fallback intact for art-less groups.
Gate: tsc/lint/knip/prettier clean, 423 vitest; backend ruff clean, collections tests green
(+ a new art/runtime assertion).
The Browse-by-genre tiles and the Collections browse tiles were flat color-hash
gradients. Give each a 2×2 collage of its top films' poster art, with the color hash
kept as the fallback so a group with no matching art (a show-only or empty collection)
never renders blank.
Backend: a shared `top_art_keys` windowed query returns, per key (a genre value or a
collection rating_key), the top few items' rating_keys — best-rated then newest, in one
query. Wired into the Discover genre tiles and the collections union endpoint; the client
renders the posters from the existing /api/plex/image/{key} endpoint, so no new image
plumbing. Frontend: a shared PosterTile component (collage + scrim + label, color-hash
fallback) replaces the two ad-hoc colored-tile implementations.
Verified live on localdev: genre tiles and collection tiles render real poster collages,
with the color fallback correctly kicking in for groups without art.
Gate: tsc/lint/knip/prettier clean, 423 vitest; backend ruff clean, 11 discover tests
(incl. a new genre-art assertion).
routes/plex/browse.py was a 1693-line god-module (libraries + facets +
collections + playlists + show/item detail + people). Split it into focused
sibling routers under the same /api/plex prefix — pure code motion, no SQL /
route-path / response-shape changes:
browse.py 1693 -> 469 (list_libraries, unified_library, facets)
collections.py (new 253) browse + admin collection editor; owns _collection_source
playlists.py (new 405) the user's orderable playlists
detail.py (new 438) show/item detail + enrichment; _lib_key lives here
people.py (new 139) cast/crew chips + person filmography
Cross-module helpers _norm_lang + _content_libs move to _shared.py (their one
home); detail imports _collection_source from collections (one-way, no cycle).
__init__.py includes the four new routers. Three DB-lane tests follow the moved
symbols (import path for _content_libs; monkeypatch targets for PlexClient /
_show_enrichment now on detail).
Behaviour-equivalent: ruff clean, 348 DB-lane pass (unchanged), parity net green.
