Create a project that demonstrates an AI-powered insurance claim adjudication system. I need it to be a grounded retrieval service that processes PDFs. The core functionality should involve a LangGraph state machine that takes a request via a POST endpoint. This system must classify the request, retrieve relevant documents, ground the answer, and verify the quote against the context. Crucially, if the confidence is low, the similarity is low, or the quote isn't in context, the system must refuse to answer and provide a structured JSON audit trail detailing which gate tripped. The output should be structured JSON, not conversational chat.
