Bugfix

The model receives the prompt (and optional system message). The run uses scorer contains_all with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Fix the bug and return corrected Python code only.\n\ndef is_weekend(day):\n    return day.lower() in ['monday', 'tuesday']\n

{
  "expected_contains": [
    "saturday",
    "sunday",
    "day.lower()"
  ]
}
