RAG works… until it doesn’t. Most failures aren’t crashes.
They’re silent: weak grounding, partial answers, confident hallucinations.

I wrote a hands-on guide showing how to measure RAG quality in Java using Quarkus + LangChain4j:
– faithfulness
– relevance
– retrieval quality
– reference-based checks

Local models. No hype. Production thinking.
