E1 Portability of Role Typed Constraint Systems

This paper examines the conditions under which role-typed constraint systems are portable across descriptive contexts without loss of standing. Portability is treated as a structural property of role preservation, not as a procedural transfer or implementation method. By exhaustion, any attempt to move constraints without preserving their role typing is shown to constitute illicit scope transport and to fail closed. The argument is declarative and non-operational, placing on record the limits of portability while avoiding any guidance on system construction, deployment, or execution.
