Deterministic Causal Dynamics for Safety-Critical Autonomous Systems - Trust-Controlled Causal Topology (TCCT) and Structural Regime Dynamics (SRD)

Safety–critical autonomous systems require causal reasoning mechanisms that remain au-ditable, deterministic, and traceable under degraded sensing, adversarial disturbances, andregime transitions. Conventional causal frameworks are typically implemented using proba-bilistic graphical models whose validity depends on distributional assumptions and stochasticindependence.This paper introduces a deterministic causal architecture in which causal structure emergesfrom trust–controlled structural dynamics rather than probabilistic dependency. The architec-ture integrates deterministic structural growth, trust–gated interaction rules, and causal graphconstruction to produce a locally finite directed acyclic graph…
