Problem

A get-only Attribute accessor that returns an object is cached, but setting the attribute doesn't clear that cache:

protected function price(): Attribute
{
    return Attribute::get(fn ($value) => new Money($value));
}

$product->price->amount; // 1000

$product->update(['price' => 2500]);

$product->price->amount; // 1000

So a resource returned right after update() shows the old value until the model is refreshed. Accessors with a setter aren't affected, since they already update the cache.

Solution

Clear the cached value at the end of setAttribute(), the same way #61962 does for JSON path updates:

$product->update(['price' => 2500]);

$product->price->amount; // 2500
