code/__HELPERS/clients.dm

/proc/is_guest_key	Returns whether or not a player is a guest using their ckey as an input
/proc/unvalidated_client_error	Proc that just logs whenever an uninitialized client tries to do something before they have fully gone through New(). Intended to be used in conjunction with the `VALIDATE_CLIENT_INITIALIZATION()` macro, but can be dropped anywhere when we look at the `fully_created` var on /client.
