Deterministic Transition Infrastructure (DTI): A Formal Topology Model for Infrastructure-Scale Execution Isolation

Deterministic Transition Infrastructure (DTI) is a formal architectural framework for infrastructure-scale execution isolation based on topology-constrained state transition control. This work introduces a deterministic transition model in which execution authority is not treated as an implicit runtime capability but as a topologically bounded and structurally gated state transformation. The proposed architecture enforces separation between control-plane topology and execution-plane realization, ensuring that no direct execution path may exist without structural transition validation. The framework defines: • Topology-constrained transition graphs• Execution rail isolation• Acyclic authority propagation• Deterministic state validation gates• Infrastructure-scale execution boundary enforcement Unlike traditional security models that focus on cryptographic containment or runtime policy enforcement, DTI treats execution authority as a structural property of system topology. This approach allows formal verification of execution pathways prior to deployment, preventing emergent authority recursion or uncontrolled propagation. This document is presented as a Pre-Standard Draft (v0.1) and proposes a foundational reference architecture for deterministic infrastructure design across distributed, computational, and cyber-physical systems.
