Live YouTube search can now use YouTube's internal InnerTube endpoint instead
of search.list, materialising results through the same enrich/provenance path
at zero API quota (search.list costs 100 units/page; scrape costs nothing, only
the cheap shared videos.list enrich is charged).
- youtube/search_scrape.py: InnerTube search returning the same page shape as
YouTubeClient.search_videos (items + continuation cursor); SOCS consent cookie,
videoRenderer walk (channels/playlists/Shorts shelves naturally excluded),
type:video filter, cached InnerTube key/version with constant fallbacks.
- routes/search.py: admin-selectable source (search_source, default scrape).
Scrape path skips the 100-unit budget pre-check and logs a zero-cost search
event so the per-user daily cap still counts it; api path unchanged. Response
carries the active source.
- sysconfig/config: new search_source key (scrape|api).
- quota.log_action: record a zero-cost action event for per-user rate limits.
Add a live YouTube search that materialises results into the shared catalog so
they render with the normal feed cards + in-app player and gain per-user state.
- YouTubeClient.search_videos(): search.list (100 units), embeddable-only, returns
flat stubs + nextPageToken; surfaces liveBroadcastContent for live filtering.
- routes/search.py GET /api/search/youtube: require_human + per-user daily cap
(search_daily_limit_per_user, default 70) + can_spend pre-check (429 on either);
drops live/upcoming, upserts channel stubs (channels.list) + video stubs, enriches
(videos.list), runs the youtube.com/shorts probe, then excludes Shorts/live and
returns feed cards in relevance order with the YouTube pageToken as the cursor.
- Provenance: videos.via_search / channels.from_search (migration 0028) flag
search-discovered rows; the feed hides them from the Library (scope=all) by default
via exclude_search_discovered, leaving the Mine feed untouched.
- quota.actions_today() counts a user's per-action events today for the cap; only the
search.list call is attributed VIDEOS_SEARCH so the counter is exactly 1 per search.
