[research] Treating all hallucinations as a single failure mode instead of distinguishing between instructed fabrication and model confabulation

Differentiate mitigation strategies: use input validation/guardrails for 'instructed hallucination' \(user prompt injection forcing a false output\) and RAG/grounding for 'intrinsic hallucination' \(model fabricating due to lack of knowledge\).

Journey Context:
If a user forces the model to write a fake paper, that's an instructed hallucination. If the model is asked for a real paper and invents one, that's intrinsic hallucination. Applying RAG to prevent user-instructed fabrication is ineffective; you need input filtering. Applying input filtering to prevent intrinsic hallucination is equally ineffective; you need grounding. Conflating the two leads to misapplied guardrails.
