Periodic scheduler (configurable round duration) that closes a round only once all broadcast bets confirm, waits for the next block after closing, draws a winner via block-hash-seeded modulo over participants ordered by broadcast time, triggers the 70/30 payout, and only opens the next round once that payout confirms. Draw logic is isolated in draw.py as a deliberately simple, replaceable component. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
