Debug-Snapshot-Test-Flake-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 snapshot test includes generated IDs and current timestamps, failing intermittently even when behavior is correct. Identify the test bug and fix.
