1. x402.config preflight     — validate (payChain, payToken, payTokenContract)
                                 against the merchant's authoritative config
2. estimatePrice (GOAT-side) — quote totalWei in the GOAT-side stablecoin
3. commit (GOAT)             — bind (GOAT-side stablecoin, totalWei) into
                                 the on-chain commit hash
4. waitForCommitment         — poll until block.timestamp ≥ revealAt
                                 (minCommitmentAge = 60s; CLI default
                                  timeout 180s)
5. x402.createOrder          — pin commitMaxAmountWei so the backend
                                 re-derives a matching hash
6. x402.submitSignature      — user signs the calldata typed data
7. x402.payOrder             — broadcast payment-chain ERC-20 transfer
                                 (e.g. 3 USDT on BSC)
8. poll getOrderStatus       — until INVOICED (true success) or terminal
                                 failure (FAILED / EXPIRED / CANCELLED)
