  "description": "A binding as it travels (SPEC §3, §6): body and sig_id are required, sig_addr optional (absent = unproven, §6.1). sig_addr's format is the method's business: for monero a SigV2 string, for ed25519-test a multibase signature; the verifiers accept any JCS value there for a method they have no routine for (parity vector binding_unknown_method_sig_addr_number is reported unsupported), so it is typed only as a JCS value. No other key: SPEC §3.1, an envelope is exactly its defined members (vector binding_envelope_extra_key).",
