Reasoning-Fce-Window-Boundary

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 rate limiter says at most 10 actions in any 60 second window, implemented by resetting counters every minute. Provide a boundary counterexample.
