- ConfigPanel 'plex' group auto-renders; adds a Test-connection button + a
library-picker (checked sections write plex_libraries, applied on Save)
- api.testPlex + PlexTestResult/PlexSection types
- i18n config namespace: plex group + 7 fields + test strings (en/hu/de);
also fills the previously-missing 'downloads' group label
Every download now records the clean source page URL and shows it on the
Downloads page (open in a new tab, or copy to clipboard). The worker stores
yt-dlp's canonical webpage_url on the asset (migration 0043 adds
media_assets.source_webpage_url); the serializer prefers it and falls back to a
URL derived from source_kind+source_ref, so YouTube, external YouTube links and
external URLs (e.g. Facebook reels) all get a correct reference, and queued/older
rows work before the worker fills it. Edit clips return null (a clip's source is
the user's own earlier download, not a web page). i18n en/hu/de.
The logged-out landing probed /api/me, which 401'd, and the browser logs every
non-2xx fetch as a console error regardless of how the app handles it. The
bootstrap probe now returns 200 with {authenticated:false} via a new
optional_current_user dependency; api.me() maps that to null. The render gate
treats no-data as 'signed out' -> the landing, and a thrown error as a real
network/5xx failure. Other protected endpoints still 401, so mid-session expiry
is still caught by the global handler. Lighthouse (dev): Best Practices 96->100.
A shared-with-me item only had a download button. Add two actions (Share is intentionally NOT
offered — no chain re-sharing of someone else's file):
- Edit: the editor now accepts an accessible (owned OR shared) source, so editing a shared video
produces the editor's OWN clip in their library (counts against their quota, fully theirs
including share); the source file is only read. Route uses _accessible_job.
- Remove from my list: DELETE /api/downloads/shared/{job_id} deletes only the recipient's share
grant — the owner's job and physical file are untouched (per-user dismissal).
i18n en/hu/de. Verified in a real browser (edit a shared 70-min video → own 2:31 clip; remove
confirm shows 'won't delete the owner's file').
Rework the share dialog into two clear modes and add the public /watch player page:
- ShareDialog: (A) 'Share with a user' — autocomplete picker over registered users (was a blind
email box that 404'd on non-users); (B) 'Share a link' — create/list/copy/revoke public links
with allow-download toggle, optional expiry (1/7/30d), optional password; per-link view count.
- WatchPage: standalone login-free player at /watch/<token> (routed in main.tsx like /privacy),
self-contained mini-i18n (en/hu/de by browser language); password gate → unlock → play; shows a
Download button only when the link allows it.
- api: ShareLink/ShareRecipient types + link CRUD + recipients; share i18n (en/hu/de).
Verified end-to-end in a real browser: user picker, link create, public playback, stream-only vs
downloadable, password gate + unlock, no console errors.
Rework VideoEditor around a segment cut-list: N draggable cut markers → segments, per-segment
keep/drop (eye toggle + dropped hatch), output = Separate files (one job per kept segment) or
Join into one (segments cut-list → one concatenated file). Per-segment numeric Start/End inputs.
Filmstrip fixed: aspect-correct tiles (no vertical squish) + YouTube-style hover-scrub thumbnail
from the sprite. EditSpec.segments type; editor v2 i18n (en/hu/de). Verified end-to-end in a real
browser (3-segment split, drop middle, join → 0:12 clip from a 0:19 source).
VideoEditor modal on a finished Library download: HTML5 <video> scrubber, filmstrip timeline
(lazy server storyboard sprite) with draggable in/out handles, draggable/resizable crop overlay,
per-edit Precise (re-encode) vs Fast (stream-copy) cut toggle, split-into-N fan-out (N trim jobs),
optional clip name. Edited clips show a 'Clip' badge; 'editing' phase gets a % bar. New api
enqueueEdit/downloadStoryboard/storyboardImageUrl + EditSpec type; editor i18n (en/hu/de).
A plain <a> file download can't send the X-Siftlode-Account header, so current_user resolved
it to the session-default account — 404 'Unknown download' when the tab acts as a non-default
wallet account that owns the file. resolved_user_id now also honours a ?account= query param
(the same wallet-gated selection the WebSocket already uses), and downloadFileUrl appends the
active account id. Verified: default account -> 404, ?account=<owner> -> 206 with the right
Content-Disposition.
Multi-account-in-one-browser (esp. with per-tab accounts) leaked one account's client state
into another via shared localStorage keys. Scope every account-specific key by the tab's active
account (accountKey/readAccount/writeAccount/useAccountPersistedState helpers), so nothing bleeds
across accounts or tabs:
- Real leaks: selected playlist, client notification history + settings, onboarding-dismissed.
- UI position: feed page, channel-manager filter/view + tables, playlist sort, Settings/Stats/
Users/Config tabs.
- Previously DB-adopted caches (theme, hints, performance mode, sidebar layout, nav/filter
collapse) — now the cache is per-account too, so there's no flash of the other account's value
on login.
Kept intentionally global: siftlode.lang (needed pre-login on the Welcome page; the DB pref still
scopes it per-account after sign-in) and siftlode.seenVersion (a per-browser 'new version' banner).
E2EE private keys (IndexedDB) and the chat-dock key were already per-user.
Two tabs in one browser can now run two different signed-in accounts at once.
- The signed session cookie stays the browser's account WALLET (account_ids). Which account a
given tab acts as is a per-tab choice held in sessionStorage and sent per-request via the
X-Siftlode-Account header; current_user honours it only for an account already in the wallet,
without mutating the cookie's default account. Switching accounts sets the header + reloads
THIS tab only, instead of the old cookie-wide switch that changed every tab.
- WebSocket can't send headers, so the per-tab account rides in the ?account= query param
(validated against the wallet).
- Logout is per-tab aware: it signs the requesting tab's active account out of the wallet
(promoting a new default only if the removed one was the default), and the tab drops its
override. A stale per-tab header account 401s just that tab instead of clearing the session.
- Serve index.html with Cache-Control: no-cache so a deploy's new hashed bundle is picked up
immediately instead of the browser running a heuristically-cached stale index.html.
- Remove owner-specific / legacy deploy files (home/prod/server compose, deploy/).
The home compose stays as a local untracked file for the maintainer's own deploy.
- Genericise infra-specific code comments (egress-proxy examples) to neutral wording.
- Replace the hardcoded contact email on the legal pages with the instance operator's
configured admin email, served via the public /auth/config and shown with a neutral
fallback — so each self-hosted instance shows its own contact.
- Rewrite README for the current app + a copy-paste self-hosting quick start (prebuilt
image + first-run wizard) with a build-from-source alternative; tidy .env.example.
A new "Saved views" filter-sidebar widget (SavedViewsWidget): save the
current filters under a name, apply one with a click (active-highlighted
when it matches), rename, delete (confirm), drag-reorder, share by link
(reuses shareUrl), and star one as the default. The default view's filters
are mirrored to localStorage so loadInitialFilters applies it synchronously
on load/F5 (an api/url share link still wins; no default → last-session
filters as before). Hidden for the demo account. EN/HU/DE.
- Live-search view: a results-count selector (20/40/60/100) replaces manual load-more (the free
scrape source pages until that many are gathered); an 'these results are temporary' banner with
a 'Clear now' button that discards them 'as if never added' (api.clearSearch) and returns to
the feed.
- Channel blocklist: a Block/Unblock toggle + 'Blocked' badge on the channel page (blocked
channels don't auto-explore and their videos are hidden), and a 'Blocked channels' section in
the Channel manager with one-click unblock. ChannelDetail.blocked from the backend.
- Admin: a 'Purge discovery' button on the Scheduler page (immediate un-kept search/explore
cleanup). EN/HU/DE throughout.
Frontend for the channel-explore feature:
- ChannelPage: banner/avatar/stats header, Subscribe/unsubscribe, an "exploring" badge
while browsing an un-subscribed channel, Videos/About tabs. Reuses Feed scoped to the
channel (scope=all + source=all so the per-user ephemeral videos show). Auto-ingests
recent uploads on first visit (background, with a loading note) + "Load more from
YouTube" to page deeper; skipped for demo / already-subscribed channels.
- App: openChannel/closeChannel as a Back-aware sub-view (history.state._chan, mirrors the
YT-search _yt pattern); ChannelPage takes over the content column, nav rail stays.
- ChannelLink/cards/player: the channel name now opens our channel page (onChannelFilter →
onOpenChannel); the in-card "only this channel" filter button is dropped (the page
subsumes it). PlayerModal channel-name wiring follows in the next commit.
- api: channelDetail + exploreChannel; ChannelDetail/ExploreResult types.
- i18n EN/HU/DE: channel namespace, explore_cleanup scheduler labels, explore config group,
channels_explore quota label.
The search response now reports its source; in scrape mode (zero quota) the
results banner and Load-more button drop the 'uses quota' wording. Adds the
search_source toggle's labels/hints and updates the per-user-limit hint to note
the cost only applies to the api source. EN/HU/DE.
Replace the binary 'show search-discovered' toggle with a 3-way Source selector in the
Library toolbar, so users can also see ONLY search-discovered videos — not just hide or
mix them. Backend: feed param library_source = organic (default, hides via_search) | all
(both) | search (only via_search), applied in scope=all. Strings in HU/EN/DE.
Surface live YouTube search in the existing feed, triggered explicitly so the
expensive API call is never per-keystroke.
- Header: the search box still filters the local catalog as you type; Enter or a
YouTube button escalates the term to a live search (hidden for the demo account).
- Feed: a dedicated infinite query renders results in the same VirtualFeed cards +
in-app player, under a banner with a back button and a quota note. No auto-paginate
(each page spends 100 units) — an explicit 'Load more (uses quota)' button instead;
quota/limit errors (incl. 429) shown inline. The empty local feed offers a
'Search YouTube for <q>' CTA.
- Library: a 'Search-discovered' toggle reveals search-ingested videos (hidden by
default); sent as exclude_search_discovered.
- Admin: search_daily_limit_per_user config field; new videos_search quota label.
- All new strings translated in HU/EN/DE.
A Messages tab in the notification center (hidden for demo): set up secure
messaging with a passphrase (key generated + wrapped in-browser via WebCrypto,
stored non-extractable per device), unlock on other devices, then chat with
end-to-end encrypted, live-delivered messages. The server-authored Siftlode
welcome is readable before any key setup.
- lib/e2ee.ts: ECDH P-256 + HKDF + AES-GCM, PBKDF2-wrapped key, IndexedDB.
- lib/messagesSocket.ts: WebSocket client with backoff reconnect.
- Messages.tsx: key gate, conversation list with decrypted previews, directory,
thread with client-side decrypt + encrypt-on-send. Unread feeds the nav badge.
EN/HU/DE strings.
Render only the visible rows via @tanstack/react-virtual (useVirtualizer
against the app's <main> scroll container, per-row dynamic measurement),
so the DOM no longer accumulates every loaded card. A ResizeObserver keeps
the responsive grid column count in sync and chunks cards into virtualized
rows; the list view virtualizes single-card rows. Infinite scroll now
triggers from the virtual range and pages via next_cursor instead of
offset; feed/count drops its unused paging args.
- /api/me exposes instance-wide google_enabled. The onboarding nudge no longer auto-opens, and
Settings hides the YouTube-access section + the 'Connect Google' option, when the instance has
no Google OAuth configured (e.g. an email+password-only self-host). A linked account still shows
its 'Connected' status.
- Multi-step first-run wizard (intro → admin → Google → SMTP → finish), shown by App while the
instance reports configured=false; the one-time token comes from the setup URL (?token=) and is
sent as X-Setup-Token on every step. Google/SMTP steps appear only when secrets can be stored.
- App holds the 'me' query until setup status is known (so it doesn't 503 against the setup lock);
a missing/invalid token shows a 'use the link from the logs' screen. EN/HU/DE.
- Build the Google OAuth client lazily from sysconfig (DB override, env fallback) and re-register
when the credentials change, so the install wizard / admin can set them without a restart.
- New 'google' config group (google_client_id/secret, encrypted) on the Configuration page; the
token-refresh reads the creds the same way.
- Public GET /auth/config exposes google_enabled; the login page hides 'Continue with Google'
when Google OAuth isn't configured (email+password still works).
- Link a Google account to a password account, and adopt the Google identity onto a matching
email account instead of 500ing on a duplicate; set or change a password from Settings.
- Expose has_google/has_password on /api/me for the Sign-in methods UI.
- Mark Google logins email-verified (backfill existing rows, migration 0024); stop a routine
login from clobbering an admin-assigned role (env ADMIN_EMAILS stays the bootstrap admin).
- Suspension login-gates (password + Google callback + current_user) with a rate-limited
'suspended' notice; shared purge_user (cascade delete + access-request cleanup + Google-grant
revoke) behind self- and admin-deletion; single app_base source for user-facing email links.
Add DELETE /api/me/account: permanently erases the signed-in account and all its
personal data — OAuth tokens, subscriptions, tags, video states, playlists,
notifications all cascade on the users row (FK ON DELETE CASCADE); quota-audit
events are kept but anonymised (SET NULL); the email's invite/whitelist row is
removed too. Guards: the shared demo account can't be deleted, and the last
remaining admin can't delete itself. Frontend: a Danger zone in Settings -> Account
(non-demo) with a danger-confirm; on success the session clears and the app lands
on the welcome page. EN/HU/DE. Verified via curl: self-delete + session clear +
demo 403.
Replace the old Google-only login card with a public landing page (Welcome.tsx):
hero + auth card (email+password Sign in / Create account / Forgot password,
Continue with Google, explicit Try-the-demo) over a feature pitch (6 pain->solution
cards) and demo-account screenshot slots (graceful placeholder until the images are
dropped into frontend/public/welcome/). Auth forms wire to the 5a endpoints; errors
show inline via a new req() quiet flag (no global modal for a wrong password).
Handles ?verify, ?reset (set-new-password form), ?access banners. EN/HU/DE.
Verified end-to-end on a fresh load: render, register->approve->password-login.
New admin-only Users page (sidebar): Users & roles (list + promote/demote with
confirm; self/demo/last-admin guarded server-side), plus the Access requests
(Invite whitelist) and Demo whitelist+reset migrated out of Settings → Account
(same data/tables — UI relocated only). Settings → Account now holds personal
content only. ConfigPanel learns a boolean field type (toggle) for the new
allow_registration setting. api methods, new 'users' page/route/nav/header, and
EN/HU/DE strings (new users namespace + access group).
New admin-only Configuration page that renders the system_config registry grouped
(Email/SMTP first), with per-field save/reset, write-only encrypted secret fields
(disabled with a hint when TOKEN_ENCRYPTION_KEY is unset), and a Send-test-email
button. New 'config' page + sidebar nav item + header title; api methods and
EN/HU/DE strings.
The header's sync indicator spun "fetching history" whenever any channel
still lacked full history — i.e. perpetually, even when the scheduler was
idle between its periodic runs. It now spins only while a channel-sync job
(backfill or RSS poll) is actually running; otherwise pending deep-history
work shows as the calm, static "N without full history" link, and recent
work queued for the next run shows a static "N queued". This makes the
header coherent with the Scheduler dashboard's live state.
Backend exposes running_job_ids() from the scheduler activity and a derived
sync_active flag on /api/sync/my-status.
Add a "Discover from playlists" tab to the Channel manager that lists
channels appearing in the user's playlists they don't subscribe to, with
a one-click Subscribe.
- GET /api/channels/discovery: local join (playlist_items -> videos ->
channels) minus the user's subscriptions and their own channel. Enriches
stub channels' metadata up front (title/thumbnail/subscriber count via the
API key) so the user can judge a channel before subscribing; videos are
not pulled (the scheduler picks those up).
- POST /api/channels/{id}/subscribe: write-scope gated, subscriptions.insert
+ local Subscription with the returned resource id.
- YouTubeClient.insert_subscription / get_my_channel_id.
- users.yt_channel_id (migration 0019) caches the user's own channel id so
discovery can exclude it.
- Frontend: ChannelDiscovery DataTable, Channels tab toggle (persisted),
api methods, trilingual strings. Subscribe ships a typed notification
payload (ChannelSubscribedMeta) for the inbox to act on.
Settings-page prefs (theme/scheme/dark-mode/list-view/perf/hints/font + the
notification settings) were each auto-saved to the server on every toggle via
fire-and-forget savePrefs().catch(() => {}) — silent on failure, and no
positive confirmation on success, so the user had zero feedback either way.
Make them a draft instead: changes apply locally for instant preview but
persist only on an explicit Save (or revert on Discard). App owns the live
draft + the last-saved baseline, computes dirty, and exposes a controller to
the panel. The panel shows a Save/Discard bar with 'Saving…' → 'Settings
saved' (auto-clearing) / 'Couldn't save' feedback. Leaving the page with
unsaved changes prompts a confirm (in-app nav + browser Back), and a
beforeunload guards reload/close. savePrefs is now idempotent so the Save
survives a transient gateway blip; failures surface via the connection-lost
status. Language & sidebar layout stay instant (edited outside this page).
New i18n keys settings.save.* / settings.unsaved.* in EN/HU/DE.
The notice promised 'this will clear once it's back', but nothing ever
removed it: the toast auto-hid on a 15s timer (not on recovery) and the
v0.9.0 unified inbox kept every notify() in persistent history, so the
notice lingered there forever.
Model it as a single live status instead: one sticky, transient (never
persisted) notice while the server is unreachable, removed the moment any
request reaches the server again. Adds a 'transient' notification flag
(sticky toast + excluded from history so a reload can't orphan it) and
replaces the throttled-toast helper with a connectivity lost/restored pair.
i18n the strings (errors.offline.*) in EN/HU/DE — they were hardcoded English.
Retry GET (and opt-in idempotent writes: setState/clearState/saveProgress)
once on a fresh connection after a network error or 502/503/504, masking a
transient proxy<->upstream keepalive reset. If it still fails, treat
502/503/504 as the soft self-clearing 'Connection lost' toast instead of the
blocking error modal — a gateway that can't reach the app means 'restarting',
not a request the app refused. Genuine 500s keep the modal.
Expose the maintenance job's rolling re-validation batch (videos re-checked per
run) as an admin control on the Scheduler dashboard, stored in app_state
(migration 0018; NULL = the env/config default). The job reads the effective
value each run via a state helper, clamped to a sane range. Trilingual.
Add per-job "Run now" buttons and a "Start all now" button to the admin Scheduler
dashboard (admin-gated endpoints). Triggers run the job in a background thread
independent of its interval, refusing a concurrent run (409). While running, the
long jobs (maintenance, enrich, backfill, shorts) report live progress through a
decoupled contextvar sink, shown as a progress bar on the job row via the existing
4s poll. A manually-triggered run posts a completion notification to the triggering
admin's inbox (scheduled runs stay silent to avoid spam); the inbox renders the
"scheduler" type trilingually from type+data. While here, give the maintenance job
its missing dashboard label/description in all three languages.
Add a server-backed notification center that coexists with the client-side
transient bell: a per-user `notifications` table (type/title/body/data JSON/
read/dismissed), a `/api/me/notifications` CRUD API (list, unread_count, read,
read_all, dismiss, clear), and a left-nav inbox module with a live unread badge
polled via useLiveQuery. Known types render trilingual text from type+data
(English stored text is the fallback); read rows are trimmed past a soft cap.
Also adds the schema the maintenance job builds on: videos.list?part=status
columns (embeddable/privacy_status/upload_status) and the validation lifecycle
columns (last_checked_at, unavailable_since, unavailable_reason).
Page-id validation is centralized in one PAGES source of truth (isPage) so the
new page survives reload without a second allowlist to keep in sync.
- Channel-row tags show only what's attached; a '+' opens a per-channel picker. Clicking a tag
filters the feed by it; a 'Your tags' sidebar widget makes that filter visible/clearable.
- Tag manager dialog (add/rename/delete; delete only confirms when the tag is in use), reachable
from the Channel manager and the feed sidebar; hovering a tag's count lists its channels, each a
link that focuses it in the Channel manager (DataTable gains an external filter input).
- Video cards get a reset action that clears all watch state (incl. an in-progress position).
- api.req() now raises the error dialog on 5xx and 400/409/422 with the server's reason.
- Add Last upload, total Length and a Normal/Shorts/Live breakdown, computed on read in the
existing grouped query (~35ms over the full catalog — measured, so no denormalization).
- Subscribers shown compact (919K), since the YouTube API already rounds them.
- Tag cell now shows only the tags actually attached to a channel; a '+' opens a per-channel
picker to attach/detach, instead of listing every user tag on every row.
POST /api/channels/{id}/reset-backfill (admin-only): clear the channel's backfill
markers, re-opt into deep backfill and re-run its recent pull now — a re-fetch-from-
scratch trigger regardless of current sync state. Idempotent (videos upsert by id).
Each job shows a tooltip (what it does + what happens if it stops), a status
dot legend + per-dot tooltips clarify the colours, and the interval is inline-
editable (pencil -> number -> save) wired to the new PATCH endpoint. HU/EN/DE.
New admin Scheduler page (left-nav entry) with a live, self-refreshing view of
job activity, queued work and quota. Polling is factored into a reusable
useLiveQuery hook (pauses when the tab is unfocused) that the notification bell
and future yt-dlp job queue will reuse instead of re-implementing.
Login page quietly probes /auth/demo (debounced) as a valid email is
typed/pasted and reloads into the app on a match — no visible button.
Demo sessions default to the whole library, get a one-time shared-account
warning, never see the YouTube-connect onboarding/access UI or sync
actions, and admins get a demo whitelist + reset panel in Settings.
Track every account that completes OAuth in a browser session (session 'account_ids',
~14-day cookie), so the user can switch between them without another Google round-trip.
New GET /api/me/accounts (switchable accounts, active flagged) and POST /api/me/switch
(guarded: target must be in the session list — proof it signed in here — and re-checked
against is_allowed in case the invite was revoked). Logout now signs out the active
account and falls back to the most recent remaining one, else clears the session. UI: the
account popover lists the other signed-in accounts (click to switch, reloads) plus an
'Add another account' action (-> /auth/login, which uses prompt=select_account).
Trilingual. Third step of Epic N.
The in-session undo/redo is lost when switching playlists, leaving no way to undo
local edits to a YouTube-linked list afterwards. Add a per-playlist 'Reset to YouTube'
action (shown when a linked playlist is dirty) that force-repulls that single playlist
from YouTube, replacing its items/order/name and clearing dirty — even though the bulk
read-sync skips dirty playlists. Backend: repull_playlist() + POST /api/playlists/
{id}/revert-youtube (read-scope gated). Confirm dialog (destructive). Trilingual.
1) Fix: the selected playlist is now persisted (localStorage) and scrolled into view,
so F5 keeps it instead of jumping to the first one.
2) Consolidate the in-detail sort: one key select (Title/Duration/Channel) + an
asc/desc direction toggle (was separate A-Z / Z-A / shortest / longest options);
add Channel as a sort key. Direction also orders the channel groups when grouping.
3) Left rail sorting: by name / item count / total length, asc/desc, plus an
'unsynced first' toggle that floats playlists with unpushed edits to the top.
Backend: list/summary now return total_duration_seconds (grouped sum). The rail
also shows each playlist's total length. Sort prefs persist to localStorage.
Editable local playlists get an Export/Sync to YouTube button (write-scope gated):
it fetches a dry-run plan, shows a confirm with the change counts, quota estimate
and divergence warning, then pushes. An 'unsynced changes' badge and an accented
YouTube icon mark linked playlists with local edits. Deleting a linked playlist
offers 'delete on YouTube too' vs 'here only'. Trilingual strings (HU/EN/DE).
Show YouTube-sourced playlists with a YouTube icon; they're read-only for now (no
rename/delete/reorder/remove, excluded from the add-to-playlist popover) with a
'synced from YouTube' note — editing comes with the write-back phase. Add a 'Sync from
YouTube' button in the Playlists rail (api.syncYoutubePlaylists) with a result toast.
Trilingual strings.
The old per-video status='saved' becomes membership in a built-in, undeletable
'watch_later' playlist. Migration 0012 moves existing saved videos into each user's
Watch later list and demotes the states to 'new'. The feed/playlist serializers now
expose a 'saved' boolean (EXISTS in watch_later); the card bookmark toggles watch_later
via new /api/playlists/watch-later add/remove endpoints (create-on-demand) instead of
setting a status. Removed the 'saved' show-filter and status. Watch later shows a
localized name and hides rename/delete in the Playlists page and add-to-playlist popover.
Add the Playlists page (left rail of playlists + detail with drag&drop reorder,
inline rename, one-step delete, remove item, Play all / row-click playback via the
existing PlayerModal) and an AddToPlaylist popover (portaled, multi-toggle +
inline new-playlist) wired into the VideoCard hover overlay and the PlayerModal.
New api client methods + Playlist types, a 'playlists' page route + account-menu
entry, and trilingual strings. Local only — YouTube sync comes in later phases.
Topic and language chips now show live channel counts for the current filter
context instead of the static global count, and chips that match nothing are
hidden (selected chips stay so they can be cleared). Selecting a channel (or any
filter) drops the now-irrelevant chips and updates the rest. Extract a shared
filterParams() so the feed and facets queries see identical filters; the facets
query is keyed on filters so it refetches as they change. Trilingual empty-state
string when a category has no matching tags.
