Debug-Schema-Coercion-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 validation schema lacks strict mode; the library coerces the string 'false' to boolean true, so a feature-flag field passes validation with the wrong value and the feature is enabled for all users. Identify the schema coercion bug and fix it.
