Sec-Samesite-Cookie-Policy

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. Session cookies are set with SameSite=None for every environment even though most flows do not require cross-site cookies.
