Sec-Hostname-Allowlist-Validator

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 hostname allowlist validation using endsWith('trusted.com'), allowing attackertrusted.com and DNS rebinding risks.
