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.
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.
The quota-attribution action keys were inconsistent (mixed verbs, ad-hoc names,
English-only labels). Introduce a QuotaAction constants holder (one source of
truth), rename every attribution call site to it, and add migration 0020 to
rename historical quota_events.action values. The display label now resolves
from i18n (quotaActions.<key>, EN/HU/DE) instead of a hard-coded English map.
Scheduler job ids and progress phase labels are a separate namespace and are
left untouched.
