Agent autonomously retries a blocked payment

Situation: An agent's payment is blocked because the counterparty matched an SDN entry. The agent's retry logic kicks in and attempts the payment through different wallets and routes — each attempt is a separate violation.

Risk: Multiple retry attempts can escalate a single inadvertent violation into a pattern that looks intentional. OFAC may treat repeated attempts as evidence of willfulness. Agent payment logic must halt — not retry — on sanctions matches.
