Build a compiled evaluator-optimizer subgraph.
Creates a LangGraph StateGraph that implements the
evaluate→refine loop pattern. The returned compiled graph can
be used as a node in a parent graph.
Node function that refines the draft based on evaluation feedback.
Routing function that returns accepted_route or refine_route based on state.
The TypedDict class for the subgraph state.
Safety limit on refinement loops.
Route name when evaluation passes.
Route name when refinement is needed.
