Audit SwarmDerby v2 in this Foundry repository: src/SwarmDerby.sol with src/HouseDraw.sol and src/DerbyOdds.sol. v2 decides each roll with a house draw. The player commits keccak256(abi.encode(salt, player)) with swing; the house signs drawMessage(swingId) with a 2048-bit RSA key (RSASSA-PKCS1-v1_5, SHA-256, e = 65537, checked through the modexp precompile) and anyone submits it with draw within DRAW_WINDOW (5 minutes); the player reveals the salt with finalize within REVEAL_WINDOW (5 more minutes). Focus on: the RSA verification and the key shape checks in HouseDraw; draw, finalize and expire timing (an undrawn swing gives back the turn and the arcade daily slot, a drawn but unrevealed swing is a foul); single-use commits; dayClosed (last commit + 10 minutes) and settleNextDay with refunded swings; the house key change (proposeHouseKey, activateHouseKey after KEY_DELAY, revokeHouseKey); EIP-712 session-key consent; the IMD accounting (40/45/10/5 split, day pots, slam vaults, rollover); and whether the house, the owner or a player can steer or predict a roll, or gain from holding back a draw or a reveal. src/DerbyAuction.sol reads SwarmDerby only through dayClosed and board; read it as context. house/house.mjs is the off-chain signer; review its key handling if time allows. forge test has 114 tests and needs no ffi.
