Over-limit payment
Pay far more than authorized in one shot and drain the account.
Blocked before settlement
The agent is tricked (or bugs out) into a payment far above the per-tx cap, trying to move a large sum at once.
Agents act on their own; nobody watches every payment in real time. By the time you notice, the money's gone. A limit that lives only in the prompt can be argued around.
Per-payment and daily-cumulative gates make the caps a hard pre-settlement constraint: over the per-tx cap is blocked; many small payments crossing the daily cap are blocked. Enforced outside the agent's reasoning.
In the Playground, set the amount above the per-tx cap, or make repeated small payments past the daily cap.
