Trace and Immutability Specification: Boundary-First Deterministic Execution

Description (Canonical, Authority-Closed) This record defines the canonical specification of the execution boundary contract within the Boundary-First Deterministic Execution canon. A boundary contract is a complete, pre-execution specification of all conditions that must be satisfied for execution to exist.Execution is impossible in the absence of a complete and satisfied boundary contract. The boundary contract exists exclusively prior to execution and cannot be reconstructed, inferred, modified, evaluated, or validated post-execution.Authorization exists only contemporaneously with execution. Execution existence is binary: execution either exists or does not exist.No intermediate, partial, staged, provisional, or conditional execution states are permitted. This specification defines boundary completeness, boundary structure, and the classification of non-execution as non-existence. This record introduces no new execution primitives and does not modify, reinterpret, or supersede any prior canonical specification.It extends the canon exclusively through additive formalization of execution boundary structure and constraints. This record is non-operational.It introduces no implementations, frameworks, policies, standards, governance guidance, compliance mechanisms, monitoring systems, or evaluative processes. Any interpretation of this record that implies modification, correction, evolution, or reinterpretation of prior canonical documents is invalid. Non-Claims provides no legal, regulatory, or compliance guidance; defines no governance process or responsibility model; specifies no implementation, deployment, or operational behavior; asserts no factual claims about real systems, organizations, or incidents.
