peter 3f047bbad1 refactor(config): config/state mutators flush, callers commit (E3 S3, B-core-10)
Restores CLAUDE.md's canonical transaction rule ("the handler commits; helpers
flush; only quota owns its session") on the config path: sysconfig.set_value /
sysconfig.reset and state.set_sync_paused now flush instead of committing, so a
change lands in ONE transaction with the audit row the route records for it —
previously the helper's internal commit split them, and a crash between left the
mutation persisted with no audit trail.

All callers already commit (the config PATCH/DELETE + audit, the sync pause/resume
+ audit, the scheduler maintenance PATCH); the setup wizard, which relied on the
internal commit, gets an explicit db.commit() after its loop. apply_interval is
deliberately left committing — it performs a live APScheduler reschedule that must
follow the DB persist, so it owns its own unit of work (a legitimate exception,
like the download service transitions). New test locks the flush-not-commit
contract (a rollback before the caller commits discards the change). 368 pass.

peter cff8bed62b fix(downloads): heartbeat only when no write touched the row this interval (E3 review R2)
Round-2 review of the R1 fixes found that the two-independent-limiter progress
writer issued a redundant heartbeat every interval during an ACTIVE download: a
percent change writes progress (which already refreshes updated_at, the stall
watchdog's liveness source), then the sub-integer calls that follow fire the
separate beat budget — ~2 DB writes/interval instead of the throttle's intended 1.

Replace the second limiter with a shared `last_touch` clock (last DB write OR
beat). Progress writes keep their own `allow_write` budget (so a beat still can't
delay a real write — the R1 concern), but the heartbeat now fires only when
nothing touched the row for a full interval. Active download → ~1 write/interval;
a genuinely stuck re-encode → 1 heartbeat/interval. New regression test:
an unchanged-percent call in the same interval as a write does NOT heartbeat.

ruff clean, full DB-lane 365 pass.

peter bc79720e81 fix(e3): address /code-review high findings (5)
Round-1 review fixes on the E3 branch:

- prune partial-fetch (correctness): `_paginate` now reports whether it reached
  the server's reported `total`; `_prune_stale` prunes only on a COMPLETE
  non-empty listing. A truncated fetch (a mid-sequence empty/short page before
  total — a transient Plex hiccup) no longer deletes the rows it merely failed
  to list. New test: a listing that claims 5 but returns 1 prunes nothing.
- `_prune_stale` (robustness): `stats.get("pruned", 0) + 1` — no KeyError when a
  caller's stats dict omits the key.
- service transitions (conventions): pause/resume/redownload use the JobStatus
  StrEnum instead of loose "queued"/"paused"/"error" literals, matching cancel.
- ffmpeg progress writer (correctness): a stuck-percent heartbeat now runs on its
  OWN 1/interval budget, so it can't consume the progress-write slot and delay a
  real percent change by up to an interval.
- backend/app/README.md (conventions): reword the transaction-ownership rule to
  quote and extend CLAUDE.md's canonical ("handler/job-wrapper commits; helpers
  flush; only quota owns its session") instead of stating a contradicting
  "helpers MAY commit" carve-out.

ruff clean, full DB-lane 364 pass.

peter b2013a079a refactor(downloads): split worker.py parent/child into pipeline.py + jobdb.py (E3 S2, B-sub-9)
worker.py (~1090 L) mixed the PARENT supervisor (claim + supervise + the process
loop) with the CHILD pipeline (the yt-dlp/ffmpeg download+edit that runs in the
spawned subprocess). Extract them:

  worker.py  1090 -> 475   parent: claim/supervise/loop
  downloads/pipeline.py  (new 592)  the child pipeline (_download/_process_edit +
                                    hooks/progress/ffmpeg helpers + _Aborted)
  downloads/jobdb.py     (new  73)  the short-lived-session helpers both sides
                                    share (_set_job/_job_status/_touch_job/
                                    _requeue_if_running/_reset_asset_pending +
                                    the staging-dir paths)

The graph is one-directional (runner -> pipeline -> jobdb; worker -> jobdb; no
worker<->pipeline edge) — the parent never calls the child directly, it spawns
runner.py as a subprocess. Consumers rewired: runner import, and two tests follow
the moved symbols (_media_info/_produced_file -> pipeline; the ffmpeg-callback
patches target pipeline where the names are looked up).

Pure code motion, verbatim bodies. ruff clean, full lane 363 pass (unchanged).

peter 3334a8e895 test(downloads): E3 S2 characterization net — job state transitions (B-sub-8)
Pins the observable HTTP behaviour of pause/resume/cancel/delete/redownload
(status changes, asset release, failed-asset reset, fresh-asset rebuild) before
the inline route logic moves into service.* methods. Green on the current routes.

peter e2362e1ed1 fix(downloads): heartbeat a slow re-encode so the stall watchdog can't false-kill it (E3 S2, B-sub-4)
The supervisor kills a job that writes nothing for download_stall_timeout_seconds
(150s) and labels it a "network" stall. But the ffmpeg progress writer only wrote
on an integer-percent CHANGE, so a re-encode that sits on one percent for minutes
(AV1/VP9 -> H.264 or a crop on the CPU-only prod host) produced no row write and
was killed mid-encode as "stalled" — and the retry stalled the same way.

Fix: the writer now heartbeats (`_touch_job`, bumping updated_at without touching
the progress bar) once per interval even when the whole percent is unchanged, so
a live-but-quiet re-encode keeps a fresh updated_at. Reorders the rate-limit gate
first so a burst still costs one DB op — either a progress write or a heartbeat.

Pure-logic test with an injected clock: three stuck-at-10% intervals write no new
progress but heartbeat each time. Full lane green, ruff clean.

peter 7d89bc8b8e fix(downloads): exclude in-flight assets from the claim, drop the busy-wait (E3 S2, B-sub-3)
Two jobs on the same shared asset (same video+format queued twice, or by two
users) starved the worker pool: worker A downloads the asset; worker B claims the
sibling job, finds the asset `downloading`, requeues it, sleep(2)s, and re-claims
it on the next tick — burning a whole worker slot behind one in-flight asset for
the entire download (at concurrency=2, the queue stalls).

Fix: the claim SQL now excludes any job whose asset is already `downloading`
(`NOT EXISTS … media_assets.status='downloading'`), so a competing sibling simply
waits until the asset settles and the workers pick up unrelated jobs meanwhile.
The `_process_job` busy/lost-race branches drop their `time.sleep(2)` — the
exclusion keeps a requeued job out of the claim window, so there's no spin.

TDD: the new test failed on the old claim (claimed the sibling), passes now.
Full lane green, ruff clean.

peter e824fe0ae9 test(downloads): E3 S2 characterization net — ref_count enqueue/release semantics (B-sub-5)
Locks the observable single-threaded ref_count accounting before the atomic-SQL
conversion: two enqueues of one (source,format) share a single asset and stack
ref_count to 2; release keeps the asset until the last holder then frees the
ready row; a non-holding (canceled) job's release is a no-op; the decrement
clamps at 0; an errored asset is kept at zero (only ready is freed). Green on the
current RMW code (5 pass) — the fix must keep every assertion.

peter 49011940d6 feat(plex): catalog prune — delete titles that disappeared from Plex (E3 S1, B-sub-6)
A sync was upsert-only: a movie/show/season/episode removed from Plex stayed
browsable forever and 404'd on playback. Each section now diffs the rating_keys
it just listed against the stored ones and deletes the stale rows (watch-state /
playlist links cascade via the existing FKs), mirroring the collections prune
that already shipped.

Safety: the prune is GUARDED on a non-empty listing (_prune_stale returns early
when `seen` is empty), so a transient Plex glitch that yields an empty page can
never mass-delete a library — the metadata is cheap to re-sync, an accidental
wipe is the only real risk. Shows prune leaf-first (episodes -> seasons -> shows)
so a stale row is deleted directly before its parent's cascade reaches it.

Out of scope (separate follow-up): library-level reconcile of a whole removed
section + retiring the dead `PlexLibrary.enabled` column.

Tests: movie prune + watch-state cascade, the empty-listing guard (mutation-
verified — removing the guard wipes everything), show/season/episode prune.
351 DB-lane pass, ruff clean.

peter 52b6535dc6 refactor(plex): split browse.py god-module into per-concern routers (E3 S1)
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.

peter 3301976375 test(plex): E3 S1 characterization net — grid⟷facets watch-state parity
Coverage-first safety net for the E3 S1 Plex god-module split. The movie/show
watch-state predicates are currently hand-duplicated in unified_library (the
grid) and facets.wsq (the facet aggregation); this pins the invariant the
facets docstring promises — with no metadata filter active, a facet's genre /
content-rating counts equal the same counts over the grid's visible items — for
every (scope × show) combination, deriving the expected counts from the grid's
own response. Locks the two branch-sets together before they merge into one
shared helper, so the merge is provably behaviour-equivalent.

Mutation-verified: dropping the facets hidden-exclusion branch makes both tests
fail (Drama 3≠2, R 2≠1). Green on the current code (348 DB-lane pass).

peter 6116ad4bf4 refactor(feed): address /code-review high findings on the E2 stack
Review round on the E2 stack (S1-S5). No correctness bugs; the surviving
low/medium findings addressed:

- altitude (#1): extract the shared `tags_by_category` helper used by BOTH
  filtered_query (SQL tag WHERE) and feed_summary (Python facet/count), removing
  the category-grouping duplication, and add bidirectional "keep in lockstep —
  equivalence-tested by test_feed_summary_matches_count_plus_facets" comments so
  the SQL<->Python tag rule can't silently drift.
- test-coverage (#2): the /feed/summary equivalence test seeded only system tags,
  leaving the `ChannelTag.user_id == user.id` visibility branch untested. Add a
  user-owned Tag + link + two combos; the suite is now 346 (was 344) and the new
  cases pass (feed_summary agrees with /feed/count + /facets on user-visible tags).
- dead-code (#3): annotate get_feed_count, get_facets, and the FE api.feedCount/
  facets as "SUPERSEDED by /feed/summary — kept only as the equivalence oracle;
  retire together" so the intentionally-retained surface reads as deliberate.

Not changed (confirmed no-op): the search channel-name resolve (#4) is
once-per-request on a 633-row table and a deliberate pre-resolve for PERF-12's
BitmapOr plan; the facet loop (#5) already computes passes() once per
(channel, category) with a distinct exclude each, so there is no recomputation.

Gate green: ruff + 346 pytest; frontend tsc/knip/prettier (FE change is a comment).

peter 21a3aae700 perf(feed): collapse count + facets into one /feed/summary pass (E2 S4, PERF-13)
The FE fired /feed/count (1 pass) + /facets (3 passes) on every filter change =
4 full scans of the subscribed set. New /api/feed/summary does ONE grouped query
(the base filter with tags stripped, GROUP BY channel_id -> per-channel video
counts) and derives the total count + every tag's distinct-channel facet count in
Python on the ~few-hundred-row channel map, faithfully mirroring filtered_query's
channel-based tag logic + the /facets drill-down (own category dropped, unless a
conjunctive topic-AND). Returns {count, facets} — the same numbers the two old
endpoints returned.

FE: a single shared query (Feed reads .count, Sidebar reads .facets); same key +
filters, so React Query dedupes to ONE request. Invalidations repointed to
qk.feedSummary. The old /feed/count + /facets endpoints (and their now-unused FE
api/qk) are kept as the equivalence-test oracle + safety net; a later cleanup can
drop them.

New equivalence test (test_feed_views, 8 filter combos incl. cross-category,
disjunctive/conjunctive topic modes, search): /feed/summary count == /feed/count
and facets == /facets, byte-identical. Structural win: 2 requests / 4-6 queries
-> 1 request / 2-3 queries (the review measured 530 -> 144 ms). Gate green:

peter 6a35e83ded perf(feed): un-block the search GIN + inner-join the state views (E2 S3, PERF-12/16)
PERF-12: the search ORed `unaccent(channels.title) ILIKE '%q%'` straight into
the per-video predicate, which forced a full scan + detoast of every
search_vector and a per-candidate channel fetch. Pre-resolve the matching
channel ids (a few-hundred-row scan) and match `Video.channel_id.in_(ids)`
instead, so the planner keeps the search_vector GIN as a BitmapOr branch
(alongside ix_videos_channel_pub_desc). Empty match -> false() collapses the OR.

PERF-16: show=watched|hidden|in_progress used an outer join + coalesce(status,
'new'), so the planner couldn't start from the user's small video_states set.
Those views only return rows that HAVE a state, so inner-join video_states and
filter the raw column (status is NOT NULL on a present row, so it's identical).
'unwatched'/'all' keep the outer join. Dropped the now-dead position_expr.

New regression tests (test_feed_views): search returns both text- and channel-
name matches; the four watch-state views return the exact expected sets.

Measured on the prod-sized localdev reseed (prod planner, 0067/0068 applied):
- search /feed/count q=magyar: 663,463 -> 19,206 buffers (1,406 -> 31 ms; OLD
  seq-scan+detoast -> NEW BitmapOr GIN+channel index)
- search feed page: 2,908 -> 1,479 buffers (32.6 -> 1.4 ms)
- show=watched (user with 64 watched): 40,661 -> 264 buffers (~154x)

peter 8c08ea3133 perf(feed): published_at NOT NULL + range-anchored keyset for deep pages (E2 S2, PERF-15)
A nullable published_at forced the feed keyset into a non-sargable
`... OR published_at IS NULL` disjunction: with the 0067 index the planner still
applied it as a FILTER and scanned from the top of the index, so a deep `newest`
page discarded every earlier row (O(depth)).

- Migration 0068: backfill any NULLs (0 in prod) -> SET NOT NULL + DEFAULT now().
- Model: Video.published_at is now non-Optional, nullable=False, server_default now().
- feedquery: the `pub` key is nullable=False, and keyset_predicate is rebuilt
  recursively so a non-nullable leading key gets a non-strict range bound
  (`published_at <= v`) as an AND conjunct — an index range Cond instead of a
  filter. Nullable keys keep the NULL-aware OR form (a `<= v` bound would drop
  their NULL group). Equivalence proven by test_feed_keyset (all 13 sorts,
  cursor-walk == unpaged).
- Ingest paths (stub_from_playlist_item, apply_video_details, playlists sync)
  fall back to now() so they never write an explicit NULL.

Measured on the prod-sized localdev reseed at a ~50k-deep cursor (0067 index +
prod planner): OLD `Rows Removed by Filter: 50001`, 25,687 buffers / 9.16 ms ->
NEW `Index Cond: published_at <= v`, 1 row filtered, 47 buffers / 0.037 ms. SET
NOT NULL on 257k rows: 0.32s. Gate green (334 pytest).

peter 0340d0981c fix(e1): address /code-review high findings on the E1 stack
Review round on the whole E1 stack (main..HEAD). 6 findings, all low/medium,
none blocking; fixed for a clean gate-green handoff.

- plex/sync (correctness): the un-enriched cast guard compared the stored cast
  against THIS listing's length, so a trimmed Plex cast on a not-yet-enriched
  row was never applied. Compare against the listing CAP (_LISTING_CAST_CAP=20)
  instead: >cap = enriched (keep, survives a watermark reset), <=cap =
  listing-sourced (track edits in both directions). +2 regression tests.
- main (security): add X-Frame-Options: DENY as the legacy-browser fallback for
  the CSP frame-ancestors clickjacking guard.
- downloads/service (altitude): finalize_if_running now uses a SQLAlchemy 2.0
  update() construct instead of a hand-built text() UPDATE string — same atomic
  WHERE status='running', idiomatic, no identifier interpolation, no manual
  StrEnum coercion. Drops the now-unused text import.
- auth/admin (reuse): extract the SEC-10 "drop untrusted preset password + bump
  epoch" invariant into one helper (revoke_preset_password_if_unverified) so the
  Google-callback and admin-activation paths can't drift.
- tests/migrations (robustness): guarantee the shared schema is restored to head
  in a finally, so a downgrade/re-upgrade failure can't cascade into later tests.
- worker (simplification): align _finish_from_cache's display_name fill with the
  _download path's guard (no behavior change).

peter 18edbecb1e fix(auth): close the account pre-emption + wrong-account link holes (E1 S5, SEC-10/11)
SEC-10 (account pre-emption / "pre-hijack"): a password set on an account whose
email was never verified is untrusted — whoever registered the address (to
pre-empt the real owner) could have chosen it. Both the Google-adoption callback
and admin activation (_activate_user_by_email) now drop that pre-set password and
bump the session epoch when the account isn't email_verified, so a later Google
login / admin approval can't hand the pre-set password a working login. No-op for
a verified account (the legit no-SMTP flow). +2 tests.

SEC-11 (link/upgrade bound to the session default): the OAuth link/upgrade GETs
resolved to the session DEFAULT account, so a tab acting as a secondary account
would link Google / the YouTube grant to the wrong account. The frontend now
threads the active account through the navigation URL (withActiveAccount ->
?account=<active>), and _complete_link accepts any wallet account, not only the
default, so the identity lands on the account that started the flow.

The pip-audit step added in E1 S4 flagged cryptography 46.0.7 for PYSEC-2026-3552

surgical bump (only the cryptography line changed; cffi 2.1.1 already satisfies
it, no other package moved). pip-audit -r requirements.lock is now clean.

Add tests/test_security.py (there was none for the crypto primitives): the
Fernet encrypt/decrypt round-trip, decrypt_optional degrading on garbage and on a
key mismatch (the B-core-2 path), and the argon2 password hash/verify round-trip
— so a future crypto-lib bump can't silently break the token-at-rest path. Gate

peter 472cefed55 test(migrations)+fix: widen drift check to column shape; notifications.created_at NOT NULL (S2 review #2)
The drift check dropped every diff except table/column presence, so a column
type or nullability change would slip through. Add modify_type/modify_nullable
to the ops it fails on. That immediately surfaced a real pre-existing drift:
notifications.created_at was created NULLABLE by migration 0017 but the model
has always declared it NOT NULL (Mapped[datetime] + server_default=func.now()).
Migration 0066 enforces NOT NULL to match the model — safe, since the
server_default has filled every row since day one.

peter e764ca4568 test(fixtures): make the TestClient fixtures isolated and composable (S2 review)
Address the /code-review findings on the S2 test-net:
- as_user no longer sets a global `lambda: user` override that two users in one
  test would collide on; the shared current_user override now resolves the caller
  from an x-test-user header, and each returned client tags its own requests, so
  as_user(a)/as_user(b) are independent (#1).
- override_dep records the prior value per dependency key and restores it on
  teardown instead of a blanket dependency_overrides.clear(), so fixtures compose
  without clobbering each other (#5).
- a _configured fixture bakes the post-setup state into client/as_user, and the
  per-test inline monkeypatch / autouse duplicates are removed (#4).
- the feed keyset walk asserts all seeded rows surfaced before comparing, so a
  seeding regression can't make the sorts pass vacuously (#3).

The auth security mag had zero tests. Add a DB-lane suite over the real

/api/me authenticated; a wrong password and an unknown email return a
byte-identical 401 (no enumeration oracle); an X-Siftlode-Account header naming
a non-wallet account falls back to the default (impersonation gate); logout-others

The feed's cursor paging (sort_keys/order_by/keyset_predicate/encode/decode) is

videos on 2 channels with duplicate sort values and NULLs across

The DB-backed lane and the two ffmpeg tests skipped SILENTLY when the DB was
unreachable or ffmpeg was absent, so `siftlode check` could print green while

- install ffmpeg in Dockerfile.test so the thumbnail/poster tests actually run.
- `-rs` in pytest.ini so skip reasons are always visible.

Add the shared TestClient fixtures the risk-core suites build on: `make_user`
(create + commit a login-ready User), `client` (real auth/session stack, no
current_user override — for login/wallet/epoch), and `as_user` (a client
pre-authenticated as a given user, for tests that aren't exercising login).

Follow-up to the /code-review high on the S1 branch. The per-site

Introduce service.finalize_if_running(db, job_id, **fields): one atomic
`UPDATE download_jobs SET ... WHERE status='running'` that returns whether it
fired. It flushes pending asset writes first so the asset-then-job row-lock
order matches the cancel route (no deadlock), and runs in the caller's session
so it commits with the asset writes in one transaction. All five worker sites
(download/edit completion, both error paths, cache finish) now go through it,
so the invariant lives in one place. The 'job done' logs move inside the
finalized branch so a job stopped mid-completion no longer logs a false 'done'.
Add tests/test_downloads_finalize.py: running -> finalizes; canceled/paused ->
no-op.

peter 367bcebc9f fix(downloads): revive the worker cancel branch and guard terminal writes (B-sub-1)
The cancel route writes status 'canceled' but the supervisor compared against
'cancelled', so its "a route stopped it -> kill the child, free the asset"
branch was dead code. A canceled job's child ran to completion and wrote 'done'
unconditionally over the route's 'canceled'; since 'done' holds the asset but
'canceled' does not, a later delete released the asset a second time, dropping
ref_count below the live holder count and deleting a file still in use.

Add app/downloads/status.py as the single source of truth for the lifecycle
literals (JobStatus StrEnum + the HOLDING / STOPPED_BY_ROUTE sets) and use it at
the safety-critical sites: the supervisor stop check, the route cancel, and
release_asset's holding set. Make the worker's terminal done/error writes
conditional on the row still being 'running' so a child finishing just after a
route cancel/pause can no longer resurrect it. Add the missing 'canceled'
supervisor regression test.

(The full literal sweep across the downloads surface is left for the E3
downloads owner-unification; this is the data-safety subset.)

peter 9fb4db2546 fix(plex): address S6 code-review — 5 findings
1. (correctness) Show hero rating regression: PlexBrowse's show hero rendered a
   rating only when show.imdb_rating was set, so after the S6 IMDb-only change a
   show with no imdb:// entry showed no rating. Now falls back to the audience
   `rating` like PlexInfo.
2. (correctness) ratingMin column mismatch: the rating filter and the /facets
   rating_max now key off coalesce(imdb_rating, rating) — the SAME "best score"
   the badge displays — so a ratingMin picked from a shown IMDb score narrows the
   right column instead of the raw audience `rating`.
3. (altitude) HU search gap: new query.vector_match() matches EITHER vector in HU
   (or_(search_vector_hu, search_vector)) so a row with no HU twin stays findable
   by its English title; ranking still uses the HU vector. field_recheck unions
   the HU+EN per-field tsvectors in HU, staying a strict subset of the prefilter.
4. (test-coverage) Extracted the badge logic to lib/plexRating.pickRatingBadge
   (shared by PlexInfo + the show hero) with a unit test (imdb-preferred, audience
   fallback, 0-score, none). Backend tests added for the HU union search + the
   IMDb-preferred rating filter.
5. (efficiency) Language switch no longer double-fetches the grid: browseQ is
   gated on a committedLang state that lags `lang` by one render, so the
   genre-clear effect settles into a single fetch instead of one throwaway fetch
   with stale-language genres plus a second.

DB-lane suite 295 passed / 2 skip; FE tsc/knip/lint clean, 217 vitest pass.

peter 030ba7297a feat(plex): S6 backend — language-aware serving + IMDb-only rating
E5 S6 backend half (no migration — the *_hu / rich columns exist from S5a/S5b).

Language-aware serving (?lang=hu serves the HU overlay twin, EN fallback per row):
- query.py: column pickers title_col / genres_col / vector_col; field_recheck and
  meta_filter_conds take `lang`. DISPLAY/FILTER pickers coalesce(*_hu, *) (EN
  fallback); SEARCH pickers use the raw *_hu column mirroring the generated
  search_vector_hu (coalesce to '', not EN) so the field recheck stays a strict
  subset of the GIN vector (the S2 invariant). genres_col type_coerces the coalesce
  to JSONB so the GIN `.contains` survives.
- browse.py: `lang` param on /library, /facets, /item, /show (validated to en|hu).
  unified_library title/vector/rank/field-scope + meta filters are language-aware
  for both the movie and show branches; facets unnest the active-language genre
  vocabulary (jsonb_typeof guard kept); detail endpoints serve HU title/summary/
  genres/show_title with EN fallback. Episodes stay EN (not overlay-localized).

IMDb-only rating (folded-in S5b review #5):
- detail.py rich_detail: drop the audienceRating/rating fallback → imdb_rating is
  NULL when there's no imdb:// Rating entry (stop mislabelling a Plex audience score
  as IMDb). item_detail now also serves the `rating` column (audience score;
  show_detail already did) so the UI can show it when there's no IMDb score.

Tests: test_plex_lang.py (HU title serving + EN fallback, language-specific facet
vocabulary, genre-filter language matching, item_detail lang + rating split);
test_plex_detail updated for IMDb-only. DB-lane suite 293 passed / 2 skipped; ruff clean.

Second-round /code-review high follow-ups:

- test_feed_cursor.py: GET /api/feed?cursor=<garbage> must return HTTP 400
  (not 500) — locks the cursor-error path the refactor split across modules
  (feedquery.decode_cursor raises ValueError, get_feed translates to 400).
  Plus a no-cursor 200 sanity check. DB lane.
- get_feed: `raise HTTPException(...) from None` so the expected bad-input
  ValueError isn't chained as __context__.

peter 81827fcf28 fix(plex): S5b review — preserve enriched cast_names across full syncs
Address the /code-review high finding on S5b: gating the info-page cast enrich on
`people_enriched_at is None` removed the old per-view regrow of `cast_names`, so a routine full sync
that reset it to the listing top-20 (`_apply_facet_fields`) — while never clearing people_enriched_at —
left it permanently truncated, silently dropping cast past the top ~20 from the S4 person-page filter.

Root fix: `_apply_facet_fields` now only takes the listing's cast for a NOT-yet-enriched row; an
enriched row keeps its fuller stored cast (people_text still rebuilt from the updated directors + the
preserved cast). Makes the people_enriched_at flag the endpoints/backfill trust actually reliable.

Tests: cast_names preserved for an enriched row vs applied for a fresh one; show_detail lazy-fill
persists imdb/full_cast on first view. Full suite green.
2026-08-16 23:30:33 +02:00
peter 4e97fc1a84 feat(plex): S5b persist rich detail + serve item/show detail from DB
Persist the info-page rich fields that were previously read LIVE from plex.metadata() on every view —
imdb_rating (IMDb-specific, vs `rating`=audienceRating), imdb_id, tagline, and full_cast
([{name,role,thumb}]) — onto plex_items/plex_shows, and serve the detail endpoints from the row.

- migration 0065: ADD imdb_rating/imdb_id/tagline/full_cast (nullable → no rewrite/lock, unlike 0064);
  NULL people_enriched_at on movie/show rows so the existing cast backfill re-fetches each once and
  fills the new columns.
- new app/plex/detail.py: rich_detail(meta) (moved out of browse._rich_meta so sync + serve share one
  parser) + apply_rich_detail(row, meta); wired into _enrich_people_batch and the info-page lazy fill.
- item_detail: movies serve cast/IMDb/tagline/genres from the row and keep plex.metadata(markers=True)
  ONLY for markers + audio/subtitle streams (so detail survives a live-Plex outage); episodes (never
  enriched) still parse detail from that live meta.
- show_detail: serves cast/IMDb from the row; `related` stays live best-effort and also lazily fills a
  not-yet-enriched show.
- tests: rich_detail/apply_rich_detail parsing + persistence, backfill stamping, item_detail
  outage-resilience + lazy fill + episode-live, show_detail row serving. Full suite 285 pass / 2 skip;
  migration verified reversible (up→down→up).

peter 02a2102523 fix(plex): S5a review round 2 — dup-HU guard + tests for dup-guid & guid-keep
- Correctness: _sync_overlay now first-wins on a guid (a `seen` set) so a duplicate HU entry
  sharing a guid can't overwrite the applied Hungarian metadata or double-count `overlaid`.
- Test-coverage: cover the earlier dup-guid fix (both editions of a shared-guid pair get *_hu,
  counted once) and the guid-keep guard (_apply_item preserves a prior guid when the listing
  carries none, still updates on a real one).

Full backend suite 276 passed / 2 skipped.
2026-08-16 22:38:59 +02:00
peter 704c6c35d4 fix(plex): address S5a review — overlay reconcile, dup-guid, guid-wipe, tests
- Correctness (stale HU): _sync_overlay is now a full reconcile — it clears every guid-bearing EN
  row's *_hu first, then repopulates the matches, so a title whose HU twin vanished or was re-guid'd
  falls back to EN instead of keeping stale Hungarian metadata (only rows that held HU data go dirty).
- Correctness (dup guid): by_guid maps a guid to the LIST of EN rows carrying it, so two editions of
  one film both receive the overlay instead of just the last-iterated one.
- Robustness (guid wipe): _apply_item/_sync_shows keep a prior guid when a listing carries none
  (`_canonical_guid(meta) or row.guid`), so a server ignoring includeGuids can't erase the match key.
- Reuse: merged _sync_overlay's movie/show branches (only the select + item_type differ).
- Test-coverage: a full-sync test drives sync() over a stub Plex (sections + section_items +
  overlay_map) asserting pass-2 designation (metadata_lang/overlay_of), guid capture, the HU write,
  and browse exclusion; plus a reconcile test that a vanished twin clears stale *_hu.

Full backend suite 274 passed / 2 skipped.

peter c959859d29 feat(plex): S5a HU-overlay backend — schema, guid, overlay sync
Adds the storage + sync for the Hungarian-metadata overlay (the browsable EN sections gain HU
twin fields written from a paired HU section, matched by guid; no browsable HU rows).

Schema (2 migrations, ADD-only; run before the first HU sync while *_hu is NULL so the generated
column build is trivial):
- 0063: plex_libraries.metadata_lang ('en' default) + self-FK overlay_of.
- 0064: plex_items/plex_shows.guid (indexed) + title_hu/summary_hu/genres_hu (+ GIN) + a STORED
  generated search_vector_hu mirroring the EN vector (title_hu A / people_text B / summary_hu C) + GIN.

Sync:
- includeGuids=1 on section_items so the canonical guid rides the cheap listing.
- _canonical_guid(meta) (tmdb > imdb > tvdb) captured onto every EN row in _apply_item/_sync_shows.
- Two-pass sync(): pass 1 mirrors browsable (non-overlay) sections; pass 2 reads plex_overlay_map
  ('huKey:enKey', new sysconfig), designates each HU section (metadata_lang='hu' + overlay_of), and
  _sync_overlay writes title_hu/summary_hu/genres_hu onto the guid-matched EN rows.

Browse: _content_libs now excludes overlay libraries (overlay_of is None); the unified_library and
facets inline library partitions fold into it, and list_libraries/collections exclude overlays too.

Tests: DB-lane coverage of the overlay write (matched vs unmatched rows, no browsable HU rows, the
generated search_vector_hu populates), the guid parse, and the browse exclusion. Full suite 272
passed; migrations verified reversible (upgrade→downgrade→upgrade). S5b (persist the live detail
fields + serve item/show detail from DB) is the follow-up.
2026-08-16 22:16:54 +02:00
peter 8b8c077a29 feat(plex): S4 actor detail page — filmography endpoint + person subview
Backend: new GET /api/plex/person/{name} returns a cast/crew member's cached headshot plus
the movies (PlexItem, kind=movie) and shows (PlexShow) in the enabled libraries whose
cast_names OR directors include the name — the inverse of the cast → filter link. Introduce a
shared _content_libs(db) helper (enabled-library partition) and reuse it in people_cards;
S5 will extend it with the HU-overlay exclusion. Watch-state comes from PlexState / rollup
(reusing _movie_card / _show_card / state_map). DB-lane tests cover cast+director credits,
library scoping, the kind filter, unknown-name empties, and the partition helper.

Frontend: a new `person` history-subview. A cast-row click (PlexInfo cast row + the show
page's CastStrip) now opens the person's filmography page instead of filtering; the filter
gesture moves to a "Filter library by {name}" button on the page itself. PlexPersonView
mirrors PlexInfoView's fetch-wrapper + glass hero (headshot + name + credit counts) and
renders Movies / Shows as PlexPosterCard grids, with an optimistic per-card watch toggle on
the person cache. New plexPerson query key + api client + PlexPersonDetail type; HU/EN copy.

peter 80ea1918e3 fix(downloads): derive title clamp from the column + real-Postgres regression
Address review findings on the title-clamp: TITLE_MAX_LEN now reads the length straight
from Notification.title so the clamp can't drift from the column a migration would change
(single source of truth). Add a db-lane test that actually commits a >255-char title into
Postgres (end-to-end proof the truncation is gone, not just the clamp logic) and one that
asserts the constant tracks the column width.

peter 83326ecf53 fix(downloads): clamp notification title to column limit so download_gc can't wedge
A downloaded FB/IG reel's "title" is the whole caption (up to ~1900 chars). It flowed
untrimmed into Notification.title (String(255)); at the batched download_gc commit that
raised psycopg StringDataRightTruncation in pass 1, aborting the whole run so expiry
deletion, LRU eviction and orphan reap never executed (13/110 prod assets already exceed
the limit). Clamp the title to 255 (with an ellipsis) centrally in create_notification —
defending all six callers — since the full title already reaches the client via `data`
and the column is only an English fallback. Add a regression test.

peter f9681deecf feat(plex): field-scoped search (S2) + instant search typeahead
Add a search scope-pill to the Plex header search box (GitHub-style, one
field-scope at a time) and an instant typeahead of the top matches below it.

Backend (unified_library):
- New `field` param: all | title | people | summary | episode. `all` is
  byte-identical to the pre-scope behaviour (untouched weighted search_vector);
  a specific field keeps the GIN `search_vector @@ tsq` prefilter AND ANDs a
  per-column tsvector recheck, so scoped hits are a strict subset of Everywhere.
  Per-field expressions mirror the search_vector Computed def (same TS config,
  same left(summary,1000) truncation).
- `episode` scope empties the movie/show grid and title-only-matches the grouped
  Episodes section; the title/people/summary scopes suppress that section.
- Unknown field falls back to `all`. New DB-lane characterization tests
  (test_plex_field_scoped_search.py): each scope narrows correctly, field=all is
  identical to today, episode empties the grid and needs shows in scope.

Frontend:
- PlexSearchBox wraps the shared SearchBar with the scope-pill (reusing
  ActionMenu) and the typeahead; SearchBar gains generic leading/below/focus/
  keydown slots so other modules' search boxes are untouched.
- Episode scope offered only when shows are in scope (movie-only hides it),
  healed at the point of use like the sort state.
- Typeahead reuses /api/plex/library (limit=10), honours scope+field (not the
  sidebar filters), shows poster+title+year, keyboard nav (arrows/Enter/Esc),
  and jumps straight to a movie's info page or a show's drill-down via a new
  provider jumpTo hand-off (mirrors the playlistOpen pattern).
- `field` persisted per-account; en/hu labels added.

peter ecbf5737b6 test(plex): characterization net for the db.query->select conversion
Locks the observable behaviour of the previously-untested Plex query hot
paths before the 2.0 conversion, so it can be proven behaviour-equivalent:

  watch-state branches, search rank + episode grouping, pagination.
- rollup.state_map: new / in_progress / watched rollup.

peter ee2bd81254 test(backfill): lock the per-page durability and reserve-guard properties
Deep-review round 1 found the new tests asserted end-state only, so both
safety mechanisms this change adds were untested (a regression would ship
green):

- Per-page cursor durability: add test_a_mid_run_failure_leaves_the_prior_page
  _durably_committed, which fails the 2nd page's fetch after page 1 committed
  and asserts the cursor + rows are already persisted (re-read via db.expire).
  Mutation-verified: reverting to a single end-of-loop commit makes it fail
  while the pre-existing paging tests stay green — the property the original
  test could not distinguish.
- Reserve guard: add test_backfill_reserve_reached_tracks_the_boundary, driving
  real record_usage spend across the 9000/2000 default boundary and asserting
  the un-mocked quota.backfill_reserve_reached() flips at exactly remaining<=reserve.

Full backend suite: 244 passed, 2 skipped (network-gated).

peter 48285a715b refactor(backfill): centralize the reserve-yield guard and drop the per-page connection hold
Addresses the code-review findings on the immediate full-history change:

- Extract quota.backfill_reserve_reached(): the remaining/reserve compare was
  open-coded at seven sites (recent/deep/immediate backfill, explore, rolling
  revalidation, and the new per-page guard). It reads in its OWN short-lived
  session (like record_usage/log_action), so a per-page guard no longer holds
  the caller's transaction open across the YouTube fetch that follows — the
  400-page immediate run no longer pins a pooled connection idle-in-transaction
  through each network round-trip. Migrated all call sites; dropped the now-dead
  sysconfig imports in channels.py and maintenance.py.
- Simplify the deep-backfill loop: channel.backfill_done = not page_token (done
  is False on entry) plus one break, replacing the doubled `if not page_token`.
- Tests patch the backfill_reserve_reached seam directly instead of mocking
  remaining_today internals, removing the fragile dead-value budget iterator.

Full backend suite green; ruff clean.

peter e3ee1baa94 fix(backfill): finish large channels in one immediate full-history run
The user-triggered "get full history" (backfill_channel_now) capped at
max_pages=60 = 3000 videos. A channel just over that (BBC Earth: 3403
uploads = 69 pages) stopped one page short, so its tail dribbled in over
the scheduler's paced 10-minute ticks (250 videos/tick) and the button
spinner looked stuck for ~18 minutes with no visible progress.

- Raise the immediate cap to max_pages=400 (20 000 videos) so any
  realistic channel completes in the single background run.
- Make a high cap safe: backfill_channel_deep now re-checks the shared
  quota before each page and yields at the backfill reserve (previously
  quota was checked once by the caller before the whole run), and commits
  the advanced cursor after every page so a restart resumes instead of
  re-fetching — and re-charging quota for — pages already stored.
- Channel page: while loading, the button shows the live stored/total
  count and a tooltip explaining the tail finishes in the background, so a
  very large channel's paced remainder reads as progress, not a hang.

Adds deep-backfill paging tests (per-page cursor commit + resume, and the
per-page quota yield).
2026-08-15 17:13:52 +02:00
peter 5720356191 fix(channels): address R14 deep-review findings
- Make the immediate-backfill guard SYMMETRIC: run_deep_backfill now also
  registers the channel it pages in _backfill_in_progress, so it and
  backfill_channel_now mutually exclude per-channel and never advance the
  same cursor concurrently (whichever started first). The interactive cap
  moves to a separate _immediate_running counter so the scheduler's channels
  don't false-trip it.
- Attribute the immediate backfill's spend: wrap it in
  quota.attribute(user_id, VIDEOS_BACKFILL_FULL) (route passes user.id), so
  it shows under the user's full-backfill action, not the OTHER/system bucket.
- Tests: the update_channel->background-task wiring + the demo guard
  (scheduled for a real user, NOT for demo); distinct N/S/L counts (2 short
  + 1 live) so a short/live swap fails; extracted channelDetailPollMs with a
  pure unit test of the poll-or-stop predicate.
- a11y: role="img" on the fully-synced charm so screen readers announce it.
2026-08-15 07:11:50 +02:00
peter 2cc77757d9 fix(channels): address R14 code-review findings
- list_channels no longer computes the Normal/Shorts/Live aggregation the
  frontend stopped reading when R14 dropped the N/S/L table column; the dead
  ManagedChannel.count_* fields are gone too.
- Immediate "get full history" backfill now coordinates with the paced
  scheduler via a small in-flight set: capped at 2 concurrent + per-channel
  dedup, and run_deep_backfill skips a channel an immediate backfill owns —
  killing the cursor race and bounding the quota-drain burst, without losing
  the speed win.
- Add test_channel_backfill.py: the channelDetail N/S/L counts + the guard's
  no-op / cap / scheduler-skip behaviour.
- Inline the syncedChannels useMemo (its dep is a fresh array each render, so
  it never cached); fix the stale "~2-min ticks" comment (it's 10 minutes).

peter e025e0f719 fix(downloads): floor max_concurrent + stable share order (R12 S5 review)
- Floor the effective max_concurrent at 1 on the read path (quota.resolve)
  and in the claim SQL (GREATEST(..., 1)). admin_set_quota already floors on
  write and the sysconfig default's min is 1, but a stray stored 0 (direct DB
  edit) would diverge the two "at limit" checks — the SQL claim-window
  exclusion can't see a user "capped" with zero running jobs, while
  at_concurrency_limit can — reopening the starvation the fairness fix closes.
  Keeping the effective limit >= 1 makes the two checks provably agree.
- shared_with_me now orders by (created_at DESC, id DESC) to match
  list_downloads, so the newly-added 500 cap has a stable boundary among
  same-timestamp shares instead of a non-deterministic one.
- 0062 upgrade loop: rename the unused loop var "table" to "_table"
  (matching the underscore-marked "_col").

Test: a stored max_concurrent=0 flooder no longer wedges the claim loop.

peter 2a33fc0d42 fix(downloads): worker claim fairness + bounded job listings (R12 S5)
#2 — _claim_job excluded users at their concurrency limit only in Python,
AFTER a fixed LIMIT-50 fetch window. One user flooding the queue with >50
queued jobs while at their cap filled the whole window, chosen came back None,
and every other user's work past position 50 was never seen. Exclude capped
users IN THE SQL (per-user max_concurrent from the quota row, else the
sysconfig default; unlimited users never capped), keeping the Python re-check
as a race guard that can only reject, never over-claim.

#3 — list_downloads and shared_with_me loaded every job for a user with no
bound. Cap both at 500 newest-first (a shared _MAX_LIST, matching the admin
listing's existing cap); the Download Center renders newest-first and 500 is
far beyond any real manual-download history, so no frontend change is needed.

Tests: DB-backed — a capped user's 60-job flood no longer starves a user
behind the window; oldest-by-queue_pos claim, all-capped->None, unlimited
never excluded; and the list cap bounds the result set.
