Authors propose a formal framework assigning AI participation and assurance per workflow unit, executed on a 17-unit wing-spar workflow: AI-generated CAD passed all 23 deterministic checks at first attempt, while stress clauses were dispositioned ADJUDICATE for insufficient convergence evidence
This paper develops a formal framework that records, for each workflow unit, its requirement, approved operational formalization, participation and assurance regime, mechanism, fallback, evidence obligations and readiness status, distinguishing deterministic verification, statistically calibrated admission, authorized human judgement or adjudication, retained deterministic tool paths and explicit non-participation; the authors execute it on a 17-unit wing-spar structural-analysis workflow where an AI-generated CAD program passed all 23 deterministic checks at the first attempt, while stress clauses did not yield PASS because the predeclared mesh-convergence evidence was insufficient and were referred to engineering adjudication.
