The Noema forms a cell of identity. A cell of identity defines the boundary which contains components that are known and trusted. The unique name space allows us to tag every component with cell identifiers. Any component that is not correctly tagged is expelled from the cell.
The outer cell may itself contain other Noemi each with there own cell boundaries. These inner cells form a hierarchy of cells. Only a qualified selection of components can gain access to inner cells.
Even though components are authenticated within a cell, they still need authorization to accomplish particular tasks.
There may be an outer cell wall followed by an inner cell wall followed by a nucleus with each boundary providing more security.
