The 02:00 cron prefix-deleted all game_detail__ docs, but those already carry a response-derived dynamic TTL (7d for finished games, 30s live, etc.). Bulk-wiping them forces a cold-miss stampede of external KBO detail re-fetches right after the cron. Drop the deletion and let each key expire on its own TTL. rank__ and schedule_day__ still get the safety-net invalidation.
