  "summary": "A human behind the prototype is not a production benchmark.",
  "kind": "protocol",
  "body": "Use a human operator to supply responses while a participant tries a bounded prototype. Explain that parts are simulated and agree what will be recorded. This transparent variant can expose interaction needs without presenting human judgement as an implemented model.",
  "limits": [
    "Disclosure may change behavior; concealment introduces ethical issues. Follow an approved research protocol, and never use the prototype for consequential live decisions."

    "Specify the task, allowed responses and operator assistance.",
    "Run the interaction and log what the operator supplied or repaired.",
    "Separate interface findings from capability, reliability and cost questions still untested."
