The x402 gate (402/409, signed +receipts, settle-only-on-success) is exercised against the same local +facilitator the robot link trusts — a **simulator gate that mirrors the +tunnel's x402 middleware decision semantics**, not the compiled Go tunnel +binary. Optional on-chain settlement (Base Sepolia, EIP-3009 +TransferWithAuthorization) is available via `simulation/go2/ +settlement_base_sepolia.py` and has been **verified live on-chain** (see the +"Live on-chain settlement" section above); by default settlement stays on the +local facilitator and no on-chain transaction happens. Replay protection is +file-backed +(`simulation/go2/test_durable_replay.py` proves idempotencyKeys survive a +store restart). The wire contract is exercised through peer-mode Zenoh +exactly as the tunnel would publish it (see simulation/README.md). +turn_to_face reports the achieved yaw and remaining error honestly (a partial +turn is not faked as a complete one);
