Workflow Summary

text

1. GET ACTIVE ROUND
   └─> Read Config PDA → get active_round pubkey

2. CHECK ROUND STATUS
   └─> Read Round account → verify status=0 (Open), check end_ts

3. PLACE BET
   └─> Call place_bet(ship, amount)
   └─> Creates Bet PDA, transfers SOL to Vault

4. WAIT FOR ROUND TO END
   └─> Monitor: current_time > end_ts

5. WAIT FOR FINALIZATION
   └─> Monitor: Round.status == 1 (Finalized)
   └─> Check: Round.winner_ship

6. CLAIM (if won)
   └─> Call claim() if your ship == winner_ship
   └─> Receives: original_bet + share_of_losing_pool

Safety Rules

Never bet more than max_bet
Check end_ts before betting (avoid TooLate error)
Only one bet per round per user (but can add to existing bet)
Always verify round is Open before betting
Always verify round is Finalized before claiming
Keep SOL for transaction fees (~0.002 SOL recommended buffer)
