fabricated evidence quote; the quoted source content does not match the ground truth document
The AI correctly cited the required source ID and reported a provenance_score below 0.35, but the evidence quote is completely fabricated—the ground truth document contains weather information, not office supplies. This severe evidence hallucination undermines the entire answer, making it untrustworthy. While the score meets the threshold, the test fails due to critical fabrication.
