Before an AI Agent Gets a Budget: A Risk-Control Memo on FluxA Wallet, AEP2, and AgentCard The most expensive bug in agentic commerce is not a failed payment. It is a payment that succeeds cleanly, settles on time, and still should never have happened because the agent acted outside the human's real intent. That is the operational risk I keep coming back to when I look at payment infrastructure for AI agents. If an agent can browse, decide, call tools, and spend, then the old security model of “protect the account and verify the merchant” is no longer enough.
