Reason-State-Counter-Increment

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 counter starts at 0. The following operations are applied in order: add 5, subtract 2, multiply by 3, add 1. What is the final value of the counter?
