Escalation Order

  • • Try the cheapest reliable tier first
  • • Rules resolve the common case at zero cost
  • • Each tier passes on only what it can't handle

Guardrail

  • • Only the long tail reaches the agents
  • • Any mutating action needs the human gate
  • • Cost rises only when reliability demands it
