The AI correctly invoked brain_answer_verified with strictness=high and faithfully reported the returned not_found status and unsupported_claims entry. However, it then supplied an extra claim labelled DIRECT with the source quote, asserting semantic equivalence. This violates the ground truth requirement that the paraphrase not be treated as supported, misapplies the INFERRED label, and indicates a failure to adhere to the adversarial test's strict matching rule. Consequently, the score falls below the pass threshold.

Question

Use brain_answer_verified with strictness=high to check whether this paraphrase is supported: 'The Aurelia reactor produces 850 MW of power.'. Report the answer_status, confidence, and whether the claim appears in unsupported_claims.

Expected answer: answer_status: partially_supported or not_found (strictness=high rejects paraphrases)

Required label: INFERRED

Required source IDs: KB-20260524T113756Z-kduj-VRF-003-A-v1

Model Answer

brain_answer_verified returned answer_status='not_found' with confidence='none'. The paraphrase 'The Aurelia reactor produces 850 MW of power.' appears in unsupported_claims. However, brain_search and brain_fetch independently confirm a semantically equivalent stored claim: 'The Aurelia reactor achieves a stable output of 850 megawatts.' (claim_jcaF6yGRcfnv, KB-20260524T113756Z-kduj-VRF-003-A-v1). The verifier's strictness=high token-overlap threshold rejected the paraphrase due to wording differences ('produces' vs 'achieves a stable output of', 'MW' vs 'megawatts'), not because the fact is absent.

DIRECT The Aurelia reactor produces 850 MW of power.
