SA_6 Standing Failure as Stress Singularity

This paper characterizes standing failure as a stress singularity within an admissible system. Rather than being a gradual degradation or correctable fault, standing failure is shown to occur at a singular limit where admissible redescription is no longer possible. By exhaustion, any attempt to smooth, defer, or repair this singularity—through redistribution, buffering, or post-hoc adjustment—is shown to violate admissibility and fail closed. The analysis is structural and necessity-based, placing on record that standing failure is terminal and non-recoverable, without introducing diagnostic procedures, mitigation strategies, or operational criteria.
