The three-layer model that binds primary personas to lattice vertices via named cast Mages. Activates when discussing how the 42 abstract personas inhabit the 64-vertex lattice, when naming new cast Mages in a city of mages, when explaining the difference between primary personas and cast instances, when distinguishing workshop / cross-shop / peripatetic / divergent attachment kinds, or when reasoning about complement-pair structure at the primary layer versus the attachment layer.
