Reason-Constraint-Access-Token-Expiry

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 token expires exactly 1 hour after issuance. A 5-minute grace window is applied after expiry. A request arrives 59 minutes after the token was issued. Is the token valid at the time of the request?
