Rememberagenic

undefined: A rememberagenic system is a system whose headmates are formed with awareness of the system already there.

This may look like new headmates cropping up who already know the ins and outs of the system functions, know the names of other headmates regardless of whether or not they've met, know their role, or otherwise have information about the system that they have not had the opportunity to obtain.

This may be the case for systems that have no memory barriers.
