[counterintuitive] RAG eliminates hallucinations

Treat RAG as a risk reducer, not an eliminator; add retrieval evaluation, source attribution, contradiction detection, and human validation for high-stakes claims.

Journey Context:
RAG grounds answers in retrieved text, but models still misread sources, synthesize beyond them, or follow bad retrieval. Anthropic's guardrail documentation states that grounding and citation techniques 'significantly reduce hallucinations' but 'don't eliminate them entirely'. The failure modes include retrieval of irrelevant or conflicting documents and synthesis errors where the model invents details not in the context.
