Halluc-Edge-Date-Parser

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. Input 03/04/2026 may mean March 4 or April 3 depending on locale. State the ambiguity and avoid choosing a date without format metadata.
