Shared Answerability as a Condition of AI Safety: Beyond Alignment Theater and Behavioral Adequacy

This paper develops a structural account of AI safety that moves beyond behavioral adequacy, compliance language, and alignment theater. Its central claim is that safe-looking behavior is not enough. An AI system may appear aligned, harmless, polite, transparent, or well-governed and still remain structurally unsafe if it cannot be meaningfully corrected under real-world consequence. The paper proposes shared answerability as a necessary condition of AI safety. Shared answerability exists when execution, oversight, and consequence remain bound tightly enough that neither the system nor the institution deploying it can offload the cost of being wrong without revision. The argument proceeds in five steps. First, it distinguishes behavioral adequacy from structural safety. Second, it defines alignment theater as the production of visible safety without sufficient consequence-bearing architecture. Third, it argues that behaviorally adequate but structurally unanswerable systems become substitute controllers: they begin to steer decisions, workflows, and institutions without inheriting the mass of consequence attached to steering. Fourth, it shows why the standard human-in-the-loop defense often fails once machine execution outruns the metabolic capacity of human witness. Fifth, it argues that many present systems produce structural debt: the model performs coherence, safety, or relation, while the human user or institution bears the cost of its mismatch with reality. The paper concludes that the future of AI safety depends not only on better behavior, but on architectures in which neither human institutions nor AI systems can escape answerability to the consequences they help produce.
