Two related search improvements:
1) Your own live-search results now belong to your Mine feed. A new per-user
search_finds table (migration 0030) records each video you surface via your
YouTube search (the route inserts them idempotently). The Mine feed becomes
'your non-hidden subscriptions OR your search finds', and the Source filter
now applies in Mine too: organic = subscriptions, search = your search finds,
all = both (default stays organic, so the main feed is unchanged). The shared
Library keeps using the global via_search flag.
2) Feed search ranks by relevance instead of a whole-phrase substring. A custom
unaccent_simple text-search config + GIN index (migration 0031) back a
YouTube-like fuzzy match: word-order-independent, multi-word AND, prefix on
the word being typed, accent-insensitive. A new 'relevance' sort orders by
ts_rank; the channel name still matches as a substring. The rank is scaled to
an integer so the keyset cursor pages it exactly (a raw float4 breaks paging).
_filtered_query returns the rank expr so only the feed list uses it.
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.
