Reason-Constraint-Retention-Date

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, evidence, constraints. A record must be kept at least 30 days, deleted no later than 45 days, and was created on May 1. Find the earliest valid deletion date.
