Halluc-Bug-Closure-Loop

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. Code uses var i in a loop and async callbacks later log i. Identify the closure bug and avoid claiming let has identical behavior.
