Shown as it was signed, with the wallet taken out: a field named address or walletNote reads [redacted], any 0x address inside any other field reads 0x… (a vault link keeps its own, which is a public contract), and a clause quoting what a wallet holds is cut and says so. Those bytes are unchanged in the signed entry — /ledger/2 serves it verbatim, and that is what the verifier hashes.
