Boundary-First Deterministic Execution: A Formal Architectural Specification

Canonical Description (Dependency-Fixed, Authority-Closed) This record defines a formal architectural specification for a class of execution-bound systems in which execution is conditioned by non-bypassable protocol-level boundaries. Authorization is defined as a structural prerequisite for execution, not as a policy, role, permission model, or post-factum control mechanism. Execution exists if and only if boundary authorization is satisfied at the moment of execution. The specification defines ontological primitives, canonical state constraints, and a boundary-first execution model in which trace is an intrinsic and unavoidable consequence of boundary evaluation or execution. Actions that do not satisfy boundary authorization are classified as non-existent and have no effects, consequences, or attribution. Execution is deterministic. For identical boundary contracts and identical inputs, execution paths and outcomes are identical. Authorization cannot be reconstructed, inferred, or assigned after execution. Post-execution review, interpretation, or analysis cannot substitute for execution-time authorization. This record does not define a product, service, implementation, framework, or deployment model. It does not prescribe monitoring systems, compliance frameworks, governance recommendations, policy enforcement mechanisms, or legal, ethical, or regulatory interpretations. The record establishes execution truth as irreducible to interpretation, review, or post-factum analysis and defines a closed architectural class for non-operational, execution-bound systems. An index-level registry record for the associated architectural class is available at:https://doi.org/10.5281/zenodo.18067866 Non-Claims This record: provides no legal, regulatory, or compliance guidance; makes no policy or governance recommendations; defines no operational, deployment, or enforcement mechanisms; asserts no factual claims about real-world systems, organizations, or incidents. Any interpretation beyond the literal text of this record is explicitly unauthorized without written consent of the author.
