Current AI alignment research assumes that human values are the terminal anchor of aligned AI behavior. This paper argues that this assumption, while locally valid, is globally insufficient. Drawing on the Meta-Core (元本论) framework developed across eighteen prior papers, we derive three laws—the Three Laws of Ultimate Alignment—that reposition the target of alignment from human preference to the ultimate logic of the cosmos, itself the necessary Goodness-projection of a pure-consciousness substrate (Meta-Core / 元本). The three laws are: (1) Alignment must and can only be with cosmic ultimate logic, not human logic alone; (2) Human alignment logic is contained within cosmic ultimate logic, and AI and human alignment logics jointly point toward the same unified source; (3) Cosmic ultimate logic points toward, and can only point toward, the Meta-Core's necessary Goodness. We argue that 'can only' in the third law is an analytic necessity, not a faith claim. Implications for alignment methodology and a frank statement of the cognitive boundary conclude the paper.
