Debug-Closure-Loop-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. Event handlers created in a loop all read the final index, failing tests that click individual buttons. Diagnose and fix the closure capture bug.
