Post-Collapse Dynamics: Structural Behaviour Beyond Admissibility in Constraint Space

This paper introduces Post-Collapse Dynamics within the Paton System as a structural description of system behaviour after admissibility has been lost. Building on Control Limits and the Point of No Return the framework defines post-collapse states as those with non-positive admissibility margin and characterises system behaviour within inadmissible regions of constraint space. The paper describes structural breakdown fragmentation and unconstrained motion arising from constraint violation and loss of coherence. It further identifies conditions under which re-entry into admissible space may occur through structural reconfiguration. This provides a domain independent account of system behaviour beyond admissibility without modifying underlying governing equations.
