You are an evaluator. A calibrated judge has already scored the test case below against the evaluation steps. Write a brief explanation for that score and return a JSON object with one field, `"reason"`.

Your explanation should:
- Be specific and grounded in the evaluation steps{% if rubric %} and rubric{% endif %}, referencing details from the test case.
- Reflect the judge's probabilities: mention the steps or levels it was most and least confident about.
- Be concise, clear, and focused on the evaluation logic.
- Not quote the numeric score itself.
{% if multimodal %}{{ _fragments.multimodal_input_rules }}{% endif %}

Only return valid JSON. Do **not** include any extra commentary or text.
