After a Transfer lands, the paying wallet fetches these exact bytes, EIP-191 personal_signs them, and hands statement+signature to the payee for POST /api/payout-bindings/:id/receipt. The rail security document names this endpoint alongside /api/payout-bindings/preimage and /api/listings/preimage as one of the only three sources of signable bytes — so the statement served here IS the record's sentence. Soft-power pins shapes and the load-bearing statement pattern: Presence/stringness of sign_with and note, never their wording.
