Halluc-Api-Object-Assign

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. Does Object.assign() copy inherited enumerable properties from the source objects? Clarify shallow vs deep copy behavior. Avoid claiming it performs a deep copy.
