Debug-Deep-Clone-V2

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 diagnosis, fix, tests. A deepClone helper copies arrays but leaves nested objects shared, so mutating the clone mutates the original. Diagnose and fix.
