Test code referenced in Production code explicitly preventing models from being extended or having factories.

Order Product Customer

Models all define/override newFactory changing the default method signature from hasFactory, explicitly typing them to classes that are only composer PSR loaded in require-dev so don't exist in the production code base.

    /**
     * Create a new factory instance for the model.
     *
     * @return ProductFactory
     */
    protected static function newFactory(): ProductFactory

Causing this error in Production when trying to add or use factories.

Declaration of Illuminate\Database\Eloquent\Factories\HasFactory::newFactory() must be compatible with Corcel\WooCommerce\Model\Product::newFactory()  
  : Database\Factories\ProductFactory 

Even when Database\Factories\ProductFactory extends Illuminate\Database\Eloquent\Factories\HasFactory

the method signature should typed to the Factory interface as the original signature is.

    /**
     * Create a new factory instance for the model.
     *
     * @return \Illuminate\Database\Eloquent\Factories\Factory<static>
     */
    protected static function newFactory()

Or the factories should be moved into the production code and namespace (or added to a namespace that doesn't explicitly conflict with every laravel application) so they can be extending and used to fulfill the parent models method signature..
