 ### Širšie overenie kontrolovaného RAG
 
+Otázky na obsah, zadanie, ciele alebo metódy práce používajú textové výňatky
+z príslušnej akademickej sekcie, nie iba metadáta o názve a roku. Výňatok musí
+patriť požadovanej osobe, typu práce a prípadne roku. Názov, rok ani samotný
+nadpis zadania nenahrádzajú opis. Kombinovaná otázka na názov/rok aj obsah
+vyžaduje overené štruktúrované údaje aj priradené doslovné výňatky. Ak opis
+v skutočne dodaných podkladoch chýba, odpoveď ho nesmie domýšľať.
+
 `tools/rag/evaluation/json_files/verified_rag_regression.json` obsahuje
 vopred vybraných 80 známych otázok z deviatich kategórií, vrátane 10
 neodpovedateľných otázok a 52 otázok s typovanými očakávaniami.
