Report #102161

[research] RAG still hallucinates when retrieved passages are irrelevant, outdated, or contradictory

Use a strong reranker, evaluate retrieval relevance before generating, constrain answers to the retrieved evidence, inline-cite snippets, and fall back to 'I don't have reliable evidence' if source quality is low.

Journey Context:
Retrieval augments but does not guarantee factuality. Distractor documents and stale sources are often synthesized into false claims. The fix is to treat retrieval as evidence that must be cited and verified, not as a context dump, and to make the generator accountable to that evidence.
