NewVideos called search.list at 100 quota units/call. With ~143 channels one discovery pass = 14,300 units > the 10,000/day YouTube Data API cap, exhausting the whole day in a single loop (live quotaExceeded). Switch to playlistItems.list (1 unit/call) against the channel's uploads playlist. For a standard channel id UCxxxx the uploads playlist is UUxxxx, derived at zero API cost (uploadsPlaylistID). Non-standard ids fall back to channels.list (1 unit) to read contentDetails.relatedPlaylists.uploads. Newest- first ordering and MaxVideosPerSubscription cap preserved. Side effect: removing search.list also removes the accountDelegationForbidden error that endpoint threw for one channel — no separate hardening needed. New per-pass quota: /subscriptions (1) + ~1/channel discovery (143) + any channels.list fallbacks ≈ 145 units/day, well under 10k. Caption fetch (ADR-010 timedtext) uses no Data API quota.
