Closure is the fifth and final layer of the Unified Mind Architecture (UMA). This paper defines closure as the self‑terminating architecture that completes the sequence from ordered state to present state, from problem‑solving to action, and from action to structural completion. Closure is the mode that resolves open processes, stabilizes outcomes, and returns the mind to a coherent state after action has been taken. The paper formalizes the structural requirements for self‑completion, the mechanisms that govern the resolution of representational and action‑based transitions, and the boundaries that distinguish genuine closure from systems that merely halt or stop. Closure is substrate‑independent but structure‑dependent, emerging only when the full architectural sequence of cognition, consciousness, intelligence, and agency is already in place. This work positions closure as the terminal layer of UMA, completing the architecture of the mind and defining the conditions under which a system can conclude its own processes. It establishes the structural criteria for self‑completion and marks the end of the UMA sequence.
