use SilverStripe\CMS\Controllers\ContentController; is unused in this file (the controller extends PageController). Remove the unused import to avoid dead code / lint warnings.

Suggested change

use SilverStripe\CMS\Controllers\ContentController;

[Copilot]

The page-type controller class is named AboutPage_Controller, but this project uses the SilverStripe 6 convention *Controller (e.g. PageController, App\Controllers\SitemapController). With CMS 6.x the _Controller suffix is not the expected naming and may not be discovered/used. Rename the class to AboutPageController (and adjust the filename if your autoloading conventions require it).

Suggested change

	class AboutPage_Controller extends PageController
	class AboutPageController extends PageController

This adds a new Director rule for 'about', but the repo already defines an about route in app/_config/about_routes.yml ('about//$Action/$ID/$OtherID': 'AboutController'), which will also match /about. The duplicate/conflicting rules make routing order-dependent and may prevent this rule from ever being hit. Consider updating/removing the existing about rule (or changing this rule to a different URL pattern) so there is a single source of truth for the /about route.

Suggested change

'about': AboutPage

[Copilot]

Director.rules expects a controller class name (or mapping to a controller action), but AboutPage is a Page/SiteTree subclass, not a Controller. As written, this route is likely to fail or never dispatch as intended. Route to an actual controller (e.g. an AboutPageController/AboutController) or implement a controller that loads/renders the AboutPage record.

Suggested change

	'about': AboutPage
	'about': 'App\Controllers\AboutController'

private static $has_one = []; is redundant here (it matches the empty definition already present on Page). Consider removing it unless you plan to add relations, to reduce noise in the class definition.

Suggested change

	private static $has_one = [];
