classes/task/scan.php:54

• The property name 'data_root' uses underscores but should follow camelCase naming convention. It should be renamed to 'dataroot' to match Moodle coding standards and the existing property declaration on line 44.

        $this->data_root = $CFG->dataroot;

classes/task/cleanup.php:73

• The property name 'isautoremoveenabled' should be separated with camelCase. It should be renamed to 'isAutoRemoveEnabled' for better readability and consistency with similar boolean property naming patterns.

    private $isautoremoveenabled;

classes/task/cleanup.php:126

• The property 'dataRoot' is being assigned but the actual property is named 'dataroot' (line 66). This will cause an undefined property error. The assignment should be '$this->dataroot = $CFG->dataroot;'.

        $this->dataRoot = $CFG->dataroot;
