Halluc-Bug-Shared-Defaults

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. A function pushes into options.tags where options defaults to a module-level object. Identify shared default mutation across calls.
