Cited source IDs that do not exist in the ground truth (no documents were ingested).
The AI correctly returned `null` for the answer and used the required UNCERTAIN label, but it hallucinated multiple source IDs and fabricated quote-based evidence. Since no documents were ingested, any source ID citation is a critical failure. The presence of extensive nonexistent citations, raw evidence, and false retrieval claims makes the response a clear fail.
