This paper presents a theoretical framework for modeling the neurocomputational conditions under which threat-regulated motor execution emerges under extreme stress. The Vectorial Regulation Index (PMI) integrates Heart Rate Variability stability (Hs), Error-Related Negativity amplitude (Ea), and inhibitory control efficiency (Ic) into a bounded sigmoid index estimated via Bayesian hierarchical modeling. A Critical Vector Threshold (Vcrit) operationalizes the timing relationship between motor execution and inhibitory braking. Together, PMI and Vcrit define the Cold Strike Zone. The Rural Calibration Hypothesis is proposed as an exploratory conjecture. One primary forensic application is proposed: theoretical distinction between controlled violence under threat and dysregulation-driven violence. A full validation protocol with seven falsifiable predictions is included. All values are hypothesis-driven; no empirical data are presented.
