[counterintuitive] RAG eliminates hallucination

Implement strict relevance thresholds for retrieved documents and keep context minimal; use hybrid search and reranking to prevent noisy or conflicting context from being injected.

Journey Context:
Developers assume providing ground-truth context stops the model from inventing answers. However, if the retrieved documents are noisy, conflicting, or overwhelming, the model will hallucinate by blending conflicting sources or defaulting to its pretrained weights. Furthermore, the 'Lost in the Middle' phenomenon means models ignore context placed in the middle of long prompts, leading to hallucinations despite the context being present.
