Generalise the fixed-chrome pattern to the channel detail page: the banner + identity now scroll away, while the tab row and the channel feed's toolbar stick to the top as a sticky sub-header — only the video grid scrolls. Mechanism: PageToolbarSlot (the toolbar portal target) is now an exported, overridable context. ChannelPage provides its own sticky sub-header node as the target, so the channelScoped Feed portals its toolbar up next to the tabs instead of into the shell's top band. Feed always portals its toolbar now (the slot decides where it lands). Also: the page scroller now fades only its BOTTOM edge — the top is bounded by the fixed/sticky chrome, so a top fade only bit into it. E2E: adds a lock that the channel tabs/toolbar stay pinned while the banner scrolls away; suite 15/15 on :5173, tsc + knip clean.
E2E characterization (golden-master) net
Playwright tests that lock the app's five core flows — feed (scroll + filter), channel (open → back), player (open/close), settings (dirty-save + guard), and page switching — so the Platform refactor can prove it changed nothing. They assert current, correct behavior; they deliberately do not encode the known Platform bugs (those get their own specs when the sprints that fix them land).
Run
siftlode e2e # against the baked localdev :8080 stack (authoritative)
siftlode e2e-ui # same, Playwright UI mode
siftlode e2e-seed # (re)seed the test account only, no tests
The localdev stack must be up (siftlode dev). global.setup.ts reseeds the account and logs in
once, sharing the session via e2e/.auth/state.json (git-ignored).
Target — PW_BASE_URL (default http://127.0.0.1:8080):
-
:8080(baked SPA) is authoritative and same-origin. After a frontend change you mustsiftlode dev(rebuild) for its baked SPA to carry the latest test hooks. -
:5173(Vite dev) serves source live — the fast refactor loop; it proxies/apito:8080, so the stack must still be up. All five flows are proxy-safe (none use the WebSocket):PW_BASE_URL=http://localhost:5173 siftlode e2e
Account & fixture
Tests run as a dedicated, non-demo admin account e2e@siftlode.local (never a real account;
admin so the suite can reach the admin-only pages / render branches, matching the real primary
user), reset to a deterministic baseline every run by
scripts/e2e_seed.py (run
in-container so it reuses the app's models + argon2 hasher): the top-3 organic channels subscribed,
one in-progress + one watched + one saved video, prefs pinned to language: en. Credentials come
from E2E_EMAIL / E2E_PASSWORD (local-only defaults). Override the container name with
E2E_API_CONTAINER; skip the in-container seed with E2E_SKIP_SEED=1.
Selectors
The app has no data-testids of its own and all copy is i18n (en/hu), so the specs key on a thin
data-testid layer (added with this sprint) plus the locale pinned to en. Stable ARIA hooks that
already existed are used directly (role="dialog" on the player, aria-current="page" on the
active nav row, aria-pressed on the feed toggles).
Typecheck
npx tsc -p e2e/tsconfig.json --noEmit (the specs are outside the app's src tsconfig).
