An opinionated reference for building agentic RAG the way you’d actually ship it: a LangGraph state machine that decides when to retrieve, when to answer, and when to ask for more — instrumented end-to-end with LangSmith so every run is traceable and every change is measurable.

FastAPI on the back, React on the front, evaluation baked in from day one rather than bolted on later.
