Halluc-Bug-Label-Statement

The model receives the prompt (and optional system message). The run uses scorer rubric_json_metrics with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with keys answer, supported_facts, uncertainty. In JavaScript, when you use a labeled break inside nested loops, which loop does it exit? Does it jump arbitrarily like a goto statement? Avoid claiming labeled break acts as a general-purpose goto.
