Reason-Root-Auth-Cookie

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 login flow redirects back to /login after successful credentials. Given facts: cookie is set with Secure=true, local dev uses http://localhost, server reads no session cookie on the next request. Identify the most likely root cause.
