[counterintuitive] Does RAG eliminate LLM hallucination

Implement robust context ranking, deduplication, and relevance thresholds before injection; reject generation if retrieved context is below threshold or highly conflicting.

Journey Context:
The belief is that giving the model the 'right answer' in the prompt stops it from making things up. In reality, poorly retrieved or conflicting contexts confuse the model, leading to 'context-confused hallucinations' where it blends entities from different chunks. Furthermore, models suffer from the 'lost in the middle' effect, ignoring context placed in the middle of long prompts, meaning RAG can actually \*increase\* hallucination if the retrieval pipeline is noisy.
