Approval Path

  • • A sensitive action pauses the durable run
  • • State is checkpointed at awaiting_approval
  • • Approval resumes exactly where it paused

Deadline First

  • • The deadline is checked before waiting
  • • A lapsed request auto-expires without a human
  • • Stale approvals never resume

Terminal Outcomes

  • • Deny terminates the run cleanly
  • • Expiry and denial are distinct exits
  • • Neither leaves a run dangling
