An executor agent handles tasks autonomously by default; on failure or low confidence it escalates to a stronger advisor, which counsels but never takes over execution.

whyMultiAgent
A single agent either always pays for strong reasoning (expensive, slow) or always runs cheap and misses hard cases. The escalation topology lets the executor get an external perspective it structurally cannot generate for itself, but only on the cases where the cost is justified.
