The agent can call. It cannot exceed the cap.

Priya opens an $8 USDC channel on Solana’s payment-channels program. Scout, the overnight agent, buys Hyperliquid marks as 50-byte Ed25519 vouchers. Forty-one on-chain payments would break. One deposit, one settlement, unused dollars return. Scout never calls open or settle_and_seal.
