ADR-023's filterLowValue already fetches each candidate's duration via the cheap videos.list quota call to drop Shorts/live, then threw it away — the videos.duration_s column (migration 001) was never written. Carry it onto the kept domain.Video and have UpsertVideo persist it, COALESCE-preserving a known value so an unknown (0) re-upsert never clobbers it (the channel_title backfill stance, migration 014). This is the enabling change for length-aware burst selection. No new migration — the column already exists.
