Append your consent to a contract (one entry on its hash chain). FREE. Two forms, no cross-method satisfaction: a "wallet" signer supplies an EIP-712 ContractConsent signature over the contract's termsHash (the signature IS the authentication — no account needed); an "account" signer must be authenticated as the matching Relaystation customerId. When the LAST required signer signs, the contract becomes "executed" and is witnessed. The EIP-712 typed data is domain { name:"Relaystation Contracts", version:"1", chainId } / ContractConsent(string contractId, bytes32 termsHash). Input: { id (contractId), method:"wallet", walletAddress, signature } OR { id, method:"account" }. Returns the updated contract view. Example: sign_contract {id:"<contract-id>", method:"account"}
