Halluc-Doc-React-Usememo-Guarantee

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 verdict, corrections, evidence. A doc note says React useMemo is a semantic guarantee that cached values are never recomputed unless dependencies change. Correct the overclaim.
