Communication as Admissibility: Structure, Legibility, and Continuation in Cognitive Systems

This note formalises a minimal principle of communication within the Paton System: communication is constrained by structure, not merely clarity. Misunderstanding is reframed as an admissibility mismatch between sender and receiver rather than a deficit of intelligence. An idea propagates only if it can be reconstructed within the receiver’s admissible region. When structural compatibility fails, continuation does not degrade gradually but stops. This establishes a cognitive form of the Paton Admissibility Test (PAT), where informational states either propagate or terminate based on structural fit. The framework introduces legibility as a function of constraint, linking cognitive communication failure to the same boundary behaviour observed in physical and organisational systems. No new psychology is proposed; the work provides a structural reinterpretation of communication limits within a general admissibility framework.
