Halluc-Behav-Object-Key-Order

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 verdict, corrections, evidence. A bug report claims JavaScript object keys always enumerate in insertion order, including integer-like keys. Correct the enumeration nuance.
