Suspend

  • • request_info emits a pending request
  • • The run halts instead of blocking a thread
  • • Every pending request carries a request_id

Human Gate

  • • The human answers out of band
  • • No live connection is held open
  • • The answer references the request_id

Resume

  • • A fresh run replays with the answer
  • • The answer is matched to the same request_id
  • • Execution continues to the final result
