# Task 5: Default Arrangement Selection in ProFileGenerator
## QA Scenario: 'normal' arrangement auto-selected

### Test Case: testGenerateSelectsNormalArrangementWhenPresent
- Generates a song with arrangements ['other', 'normal']
- Writes to .pro file
- Reads back and verifies 'normal' is selected (not 'other')

### Result: PASS
- Song generated successfully
- File written and read back
- Selected arrangement is 'normal' (not 'other')
- Case-insensitive matching works correctly

### Implementation Details
Modified ProFileGenerator.php lines 114-127:
```php
$presentation->setArrangements($arrangementProtos);

$selectedArrangement = null;
foreach ($arrangementProtos as $arr) {
    if (strtolower($arr->getName()) === 'normal') {
        $selectedArrangement = $arr;
        break;
    }
}
$selectedArrangement = $selectedArrangement ?? ($arrangementProtos[0] ?? null);
if ($selectedArrangement) {
    $presentation->setSelectedArrangement($selectedArrangement->getUuid());
}
```
