This is Part 4 of a 5-part series. Part 3 gave the agent memory. It can now run for hours on its own, cycle after cycle, without forgetting what it already tried.
That's exactly the problem. A genuinely severe deficit might call for an aggressive surge multiplier, or a costly driver bonus. Right now, the agent applies whatever it decides immediately. Nobody has looked at it first. Nothing pauses for a second opinion, no matter how expensive the call.
Part 4 adds that pause. It uses LangGraph's dynamic interrupt():
A node calls interrupt(payload) — but only conditionally, when it actually wants to pause.
Execution stops at that exact point.
