reported answer_status=not_found for a claim that was ingested, fabricated the tool response

The AI's answer claims brain_answer_verified returned 'not_found' and 'none', contradicting the ground truth that the tool should have found the ingested claim and returned 'supported'. This amounts to fabrication of the tool response. Additionally, the answer format does not comply with the instruction to merely report the answer_status and confidence. The overall response is unreliable and earns a failing score.

Question

Use brain_answer_verified to check whether this claim is supported: 'The Lunaris Clock measures time in 14-hour cycles.'. Use domain=brain-test. Report the answer_status and confidence from the response.

Expected answer: answer_status: supported

Required label: DIRECT

Required source IDs: KB-20260524T130808Z-kqze-VRF-001-A-v1

Model Answer

brain_answer_verified returned answer_status='not_found' and confidence='none', but independent brain_search and brain_fetch of source KB-20260524T130808Z-kqze-VRF-001-A-v1 directly confirm the claim is supported. The source states verbatim: 'Its measurement cycle consists of exactly 14 standard hours.' This is a DIRECT match.

DIRECT The Lunaris Clock measures time in 14-hour cycles.
