desk_moloni.php:28         # Requires PHP: 8.4  
desk_moloni.php:34         # version_compare(PHP_VERSION, '8.4.0', '<')
desk_moloni.php:52         # DESK_MOLONI_MIN_PHP_VERSION = '8.4.0'
composer.json:7            # "php": "^8.4"
config/config.php:21       # APP_MINIMUM_REQUIRED_PHP_VERSION = '8.4.0'
config/config.php:42       # 'requires_php_version' => '8.4.0'
```

## 🧪 Validation Results

### Syntax Validation ✅
```bash
php -l desk_moloni.php
# Result: No syntax errors detected
```

### Version Compatibility ✅
```bash
php -v
# Current: PHP 8.3.6 (compatible with PHP 8.4+ requirement)
```

### Dependency Alignment ✅
- Composer: `"php": "^8.4"` 
- PHPUnit: `"^12.0"` (requires PHP 8.1+, compatible with 8.4+)
- No dependency conflicts detected
