A reorder's left-out item, a playlisted video beside one not asked about, another user's tag, and
the user's own channel link committed before the auto-tagger reads the table.
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.
~150 HTTPExceptions carried a hand-written English sentence as their detail,
shown verbatim under the Hungarian UI — in the blocking error dialog and on
every inline surface that printed HttpError.detail (sign-in, setup wizard,
change password, the passphrase gate, live search). Four also quoted an
upstream exception's text back to the user.
- app/refusal.py: `refused(status, reason, **params)` → {code: "refused",
reason, …params}; localizeDetail translates errors.refused.<reason> with the
params interpolated. "Unknown X" 404s use the existing not_found(what).
- sysconfig.set_value raises InvalidSetting (reason + bounds) instead of an
English ValueError; the three writers answer it through setting_refused.
- The Plex connection/write/image failures log what the upstream said and
answer a reason; the search scraper's failure is logged and answered as
youtube/unavailable (it crashed refusal_reason before).
- HttpError.detail now only ever holds a translated reason: a string detail
(only the framework's own can remain) is left out, so reading .detail is
safe everywhere — including destructured, the hole the raw-detail source
scan could not see. That scan and its five-file exception list are gone.
- Enforced: test_http_details.py fails on any HTTPException with a sentence
for a detail; the contract test requires every refused reason and every
not_found "what" in both languages, and no key for one that is gone.
- local/jsx-comment-text: a // inside JSX children renders as text; the rule
is ten lines in eslint.config.js rather than eslint-plugin-react's ~1800
lockfile lines.
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__.
DB-lane suite 289 passed / 2 skipped; ruff clean.
