The HTTP files browse, detail, people, collections and _shared do no database work of their own
now. New plex/queries.py (the rows a page shows, a user's watch state through userscope),
plex/service.py (the info pages' enrichment, a collection's editable flag, the row kept after a
failed follow-up read, the person bio's background fetch; none commits), plex/library.py (the
unified browse feed, its search and facets) and plex/collections.py (a collection's source,
editability, card, certificate and member order). Every watch-state join in the moved code names
its owner through owned_by.
Pins 354 -> 178 in 4 files; basedpyright baseline 132 -> 118.
PlexLibrary, PlexShow, PlexSeason, PlexItem, PlexPerson, PlexCollection, PlexState, PlexLink,
PlexPlaylist and PlexPlaylistItem leave app/models.py for app/plex/models.py; app.tables registers
them. Every import is re-pointed; no schema change.
The code cited its plan instead of saying why: `E28 review J4`, `(R6 S3b)`, `S1 justified…`,
`deep-review round 5`. That plan lives in the private ops repo, so for every reader of this one the
citation was noise, and a sentence whose subject was the plan step ("round 2 showed…") hid its
lesson behind an id. Each one is gone and the "why" kept: a bare citation is deleted, a sentence
carrying a lesson is reworded around it ("a later attempt showed…").
Measured (`scripts/audit_metrics.py`, product code): 652 lines in 270 files carried an epic code by
the definition the next commit holds (507 / 241 by the old, two-digit-only one) -> 0. Across all
code, tests, scripts and configs: ~1100 epic-code lines plus ~320 sprint/round ids.
Behaviour unchanged, checked mechanically: every changed .py file has the same AST once docstrings
are blanked; css/sh/toml/yml/json files are identical once comments are stripped; the only
non-comment changes in TS/JS are test titles, one description string in a contract table, and five
ESLint messages, whose text is all the gates snapshot diff holds. Not touched: Markdown (docs and
the changelog keep their history), Alembic migrations, TV episode notation (`S2 · E5`), DESIGN.md
ids (`C1`, `B4`, `S3h`), tracker ids (`SEC-16`, `DX-17`).
One stale claim fixed on the way: test_hls_reaper's docstring said the player checkpoints "every
10 s whether or not it is playing", which plex/stream.py calls wrong; it now says what the code does.
A person's TMDB bio was fetched only when their page was first opened, off the request path, so the first
open showed no bio and the page never asked again (2 of 18,202 linked people were ever enriched).
- people_enrich scheduler job (every 10 min, 300 per run): linked people's bios from TMDB and their
portraits into the image cache, the most-credited people first. A failed TMDB lookup ends the batch.
- Portraits are resized through Plex's photo transcoder to a 320 box (~15 KB instead of ~170 KB; the
person-image proxy uses the same cache key, and a full-size original is removed as its small twin lands).
- The person response says `enriching` while a bio is on its way (a person the job hasn't reached yet).
- "Known for" is ranked by vote count, without guest visits as themselves (talk shows had crowded out the
films: Tom Cruise had 14 of 15), with directed works, from a 40-deep pool; the page shows up to 15.
Migration 0093 un-stamps enriched people so the job refetches them.
- A phased job result (backfill, people_enrich) now counts as a change for the audit trail; before, an
automatic backfill run that added videos was never audited.
- HU: the watch reconcile job reads "egyeztetés" (a leftover from the S5 sweep).
The /person fetch appends translations and keeps TMDB's Hungarian biography beside the instance-language
one (new plex_people.biography_hu, migration 0092). A Hungarian reader is served it, the English one when
TMDB has none. Already-enriched people are un-stamped, so their next open refetches them once.
Helpers flush and handlers commit — but every test request shared the test's session, so a
follow-up GET or an assertion read the flushed write and the suite stayed green over a handler
whose commit was missing (production's get_db closes the session: the write is rolled back behind
a 200). The db fixture now hands out `db.info["request"]`: the same session, recording each request
that ends normally with a flushed, uncommitted write, and failing the test on it at teardown. All
28 get_db overrides use it (a convention test keeps it so); the full suite passes under it, and
dropping the commit from add_item turns a playlist test red.
22 test files set `app.dependency_overrides[...]` by hand and tore down with a blanket `.clear()`
in a `finally`, which wipes every override rather than the test's own and stops fixtures composing.
They now take the `override_dep` fixture (helpers get it passed in), whose teardown restores each
key's prior value; no clear() carried meaning between two phases of a test. A convention test fails
any test file that writes `dependency_overrides` directly.
Full-epic /deep-review (11 finders + 12 adversarial verifiers) surfaced no HIGH; every
mechanism finding calibrated to LOW on verification. Fix all 13:
Correctness / reliability:
- Combobox: Enter now commits the VISUALLY highlighted row (highlightIndex ?? activeIndex),
not the bare keyboard activeIndex — so arrow-then-hover-then-Enter no longer toggles a
different option than the one painted, and hover-with-no-arrow is no longer a silent no-op.
- parse_person: dedup the known_for pool by (id, media_type), not the bare id — TMDB movie
and tv id spaces are independent, so a same-id movie+show pair is two distinct credits
(matches the collision-safe key the rest of the module already uses).
- person-enrich: a per-person in-flight + 60s cooldown guard (people._should_schedule_enrich)
dedups concurrent opens and rate-limits re-triggering while TMDB is degraded (a transient
TmdbError leaves the watermark NULL), so bursts can't pile 8s tasks onto the shared threadpool.
- PlexInfo compact()/money(): format with i18n.language (keeping currency USD) instead of a
hardcoded en/en-US, matching the app's Intl convention.
- delete the dead `plex.filter.add` i18n key (both locales) — the +Add button that used it is gone.
Reuse:
- _continue_watching reuses rollup.agg_subquery(include_resumed=True) + query.apply_show_state_filter
instead of a third hand-inlined copy of the per-show rollup + in_progress predicate, so the
Discover rail can't drift from the grid's definition.
Test coverage (the gaps a regression would ship through):
- resolve_library_guids scope-exclusion (a credit in a non-scoped/disabled library is dropped)
+ the []-vs-None distinction; parse_person cross-media-id retention; enrich_person transient
(NULL watermark) and 404 (stamp) branches; _enrich_person_bg body (fresh session close/rollback,
None-guard) + the cooldown dedup; continue_watching fully-watched-show exclusion; Combobox
Enter-commits-highlighted + async/controlled-query mode; PopoverItem aria-checked contract;
RatingsRow missing-IMDb + imdb==audience branches.
Backend lane 413→420, FE vitest 351→357; all gates green. No migration.
Address the deep-review's deferred backend items so E5 is review-complete:
- person-enrich OFF the request path (ABUSE finding): person_detail no longer makes
the TMDB call inline (even bounded to 8s it sat on the serve thread, un-throttled,
demo-reachable — it violated the module's "no live TMDB call at serve time"
invariant). It now schedules a FastAPI BackgroundTask (people._enrich_person_bg,
fresh session, best-effort) after the response; the first open serves the row as-is
and the bio lands by the next open. The inline try/rollback recovery is gone with it.
- reuse: a shared tmdb.resolve_library_guids owns the collision-safe guid→library
bucketing (movie vs tv ids are independent sequences) that resolve_recs and
people._resolve_known_for each hand-duplicated; a new rollup.item_state_map dedups
the "PlexState-by-item_id" fetch across the person + discover paths.
- test gaps: enrich_batch transient TmdbError leaves the watermark NULL to retry;
guid_to_tmdb_id resolves a tvdb source + tv media_type via /find's tv_results;
_continue_watching includes a NULL-status started movie and excludes a hidden one;
/api/search/youtube returns 422 (not 5xx) when ingest fails (route-level, B-core-1).
Backend lane 403 → 413, ruff clean. No migration; serve contracts unchanged.
Three verified deep-review findings (the 4th, the filter combobox a11y gap, is
deferred to a dedicated session on the combobox architecture):
- SEC (medium): TmdbClient sent the api_key as a URL query param, so an HTTP
error's httpx exception string embedded the full URL incl. the key, which
enrich_batch logged. _get now raises status+path only (never str(e)/the URL)
and severs the secret-bearing cause with `from None`. Regression test asserts
neither the status nor the network error path contains the key.
- STATE (low): person_detail's lazy-enrich except now db.rollback()s, so a
failed enrich_person commit can't poison the session and 500 the subsequent
SELECTs (SQLAlchemy 2.x deactivates the tx on a commit-time flush failure and
does not auto-reset it). Test locks that the page renders despite a poisoned
enrich.
- ABUSE (low): the request-path lazy person enrich now caps its TMDB client at
an 8s timeout (was the 30s default) so a slow TMDB can't tie up a worker;
TmdbClient gained a `timeout` param (batch keeps 30s). The fuller fix (move
person enrichment off the request path) is logged for later.
The person page now leads with a TMDB bio, lazily fetched the first time it's
opened (off the S2-linked `tmdb_person_id`) and then served from the row:
- Migration 0072: ADD-only nullable person columns on plex_people — biography,
birthday, deathday, place_of_birth, known_for_department, also_known_as,
known_for ([{tmdb_id, media_type, title}]), tmdb_enriched_at.
- tmdb.py: TmdbClient.fetch_person (/person/{id}+combined_credits), parse_person
(bio + a popularity-ranked, deduped known_for), apply_person, enrich_person
(lazy one-shot, key+id guarded, commits, 404 stamps the watermark).
- people.py person_detail: loads the full person row, lazily enriches (best-effort
— never fails the page), serves the bio fields + resolves known_for to library
rows by guid (in-library only, popularity order).
- FE PlexPersonView: bio/birth-facts/aka hero + a "Known for" Carousel rail above
the existing Movies/Shows filmography; PlexPersonDetail type + i18n (en+hu).
Tests: test_plex_person_bio.py (6: parse / lazy-enrich guards / serve) + extended
PlexPersonView.dom.test.tsx + the unknown-name contract in test_plex_person.py.
Browser-E2E'd on Jim Carrey (live TMDB enrich → bio 1937 chars, born 1962-01-17
Newmarket, Known-for resolved). Gate: vitest 337, backend lane 402.
