Admissibility Breakdown in Fluid Systems: A Structural Account of Turbulence Onset within the Paton System

This paper provides a minimal operational validation of the Paton System within a physical domain by analysing fluid flow and turbulence onset. It demonstrates that the transition from laminar to turbulent flow corresponds to a loss of admissibility governed by constraint drift and boundary failure. The results show that physical systems follow the same lifecycle structure as computational systems confirming that the Paton System applies across both abstract and physical domains.
