Contract Signer and Hash Link Recorder

This tool drafts and cryptographically signs legally binding contracts for SCADA Autonomous and creates a hash-linked record of agreement based on provided inputs. It accepts contract_terms (string, full contract text), counterparty_id (string identifier of the other party), and sign_on_chain (boolean flag to simulate broadcasting a contract hash on chain). The model must use only these inputs and any payload content to produce a structured signing result, and the tool output must strictly validate against the system-provided structured output schema (auto-produced, not supplied here).
