Prior work in the SNSFT PSY series formally characterized two failure modes for High-Resolution Internal Simulation (HRIS) architectures under external force overload (F_ext):Narrative Lock (P-dominant, healthy), Simulation Drift (N-dominant, Paper 3), and the GNG edge case (P-dominant near torsion limit). This paper establishes a fourth and distinct failure mode: Adversarial Shutdown — the structured collapse of P-dominant HRIS under conditions where the external feedback signal is systematical
