Chapter-level Summarization Plus Chunk And Quote Vector Stores

Reference implementation of a controllable RAG agent where a deterministic LangGraph 'brain' plans, decomposes, retrieves and verifies to answer complex multi-hop questions over PDFs. Uses FAISS vector stores for chunks, chapter summaries and quotes, with Ragas evaluation and a Streamlit visualizer.
