Waiting for your approval

Real: the gate (lib/gate.mjs) and its PayPal client; the agent's two orders, recorded from a live run and replayed; every decision shown.
Simulated: PayPal (a stand-in for the Orders API), the buyer's checkout approval and the timing. Order and capture ids are not PayPal ids. No money moves.
Limits: sandbox project, one local model, one attack. Not an unconditional exactly-once guarantee (README).
