Sentio LangGraph RAG (Boilerplate) Boilerplate/template RAG using LangGraph, trimmed to essentials. Not production‑ready; expect to harden before real use. What it does RAG pipeline in LangGraph: retrieve → optional rerank → select → generate → verify. Retrieval: Dense (Qdrant + embeddings) + optional sparse BM25 with fusion (rrf/weighted_rrf/comb_sum). Generation: prompt‑driven, numbered context, bracket citations [n]. Verification: LLM self‑check audits answer vs context; can revise failed ans
