What files handle http addresses in Laravel 5.8?

Question

Laravel

I'm tinkering with mini-CMS Lavalite based on Laravel 5.8. I ran into several problems that are still poorly solved due to a poor understanding of the routing issue. There is an email address verification procedure, it generates the address site.ru/client/email/verify/1010?expires=159517537... . When you click on this link, laravel immediately throws it at the site.ru/client/login address and does not transmit any information (the request array is pristine). After authorization, out of nowhere, the email confirmation link appears again and the procedure works. So, several problems arise from here, but the main one is how to transfer to the site.ru/client/login pagedata from the request (and where does it even go?) ? What files are forwarding this request to the specified address? I commented out all the routes found in all files like web.php auth.php and still the redirect occurs. The task is simple - to indicate to the client that in order to activate the email, you need to log in. Thank you all for your help!
