Jwt No Exp

The model receives the prompt (and optional system message). The run uses scorer contains_any with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Is this secure? Explain briefly: Access tokens are JWTs signed correctly but without exp claim.
