Import ChatOpenAI and StateGraph from langchain_openai and langgraph.graph. Initialize the ChatOpenAI model with 'o3-mini' or 'o3' for reasoning, and define a StateGraph for processing transaction validation steps.
Adaptation plan
Keep the source stable, then change the prompt in a predictable order so the next run is easier to evaluate.
Keep stable
Preserve the role framing, objective, and reporting structure so comparison runs stay coherent.
Tune next
Swap in your own domain constraints, anomaly thresholds, and examples before you branch variants.
Verify after
Check whether the prompt asks for the right evidence, confidence signal, and escalation path.
