Contextual Retrieval solves this problem by prepending chunk-specific explanatory context to each chunk before embedding (“Contextual Embeddings”) and creating the BM25 index (“Contextual BM25”).

Seven RAG approaches compared side-by-side as OpenAI-compatible endpoints (vanilla, hybrid, contextual, LightRAG graph, agentic, n8n-adaptive, experimental lazy-graph) with reproducible Ragas + judge-panel evaluation — plus a reference for consuming the Atlas platform as vendored infrastructure via a plugin seam + consumer manifest, no fork.

Production-grade RAG over Chip Huyen's "AI Engineering" book and blog. Every answer cites its exact source passage and is re-checked by a local NLI model — when evidence is missing, the system declines to answer. Hybrid retrieval (BM25 + embeddings + RRF), reranking, contextual retrieval, and a CI gate that re-checks quality on every push.
