cadrumo.core.registry_token module

Opaque text tokens whose membership a registry projection establishes.

A registry-projected vocabulary carries no closed Python member list: the dated registry owns which tokens exist and what they mean. These bases hold only the structural contract every such token shares, so a vocabulary type declares its docstring and nothing else unless its diagnostics or boundary differ.

• StrictRegistryToken admits only already projected tokens at a typed model boundary and serializes them as text.

• TextProjectedRegistryToken projects a non-empty text value at the model boundary.
