Sec-Safe-Redirect-Builder

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, risk, mitigation. Review a redirect helper that accepts arbitrary next URLs and only blocks strings starting with http://.
