Where does the answer get its evidence?

Two lanes make the preparation, retrieval and evidence decision visible.

Two-lane RAG diagram showing document indexing, retrieval, an evidence decision, and an answer with citations. — An editable diagram. The evidence check is our proposed design, not a guarantee built into every RAG system.

Document preparation builds an index. A question retrieves passages. In this proposed design, an evidence check either requests better inputs or sends the question and passages to the model. The final answer includes citations for a human to verify.
