Unified Mind Architecture (UMA)

Unified Mind Architecture (UMA) introduces a substrate‑independent structural model of the mind built from five existential operations: cognition, consciousness, intelligence, agency, and closure. Each operation is defined as an irreducible structural function, and together they form a closed adaptive cycle capable of representation, coherence, action, and self‑restoration. This paper presents UMA as a complete architectural system. It unifies the five layer‑papers into a single structural framework, clarifying how the operations interlock, how coherence is maintained across transitions, and why closure is required for the system to return to a ready state. UMA is not offered as a theory of the mind, but as the structural architecture that makes minds possible. The document establishes UMA as a formal scientific discipline grounded in structural minimalism, cross‑layer invariants, and architectural closure. It defines the system‑level relationships that bind the five existential operations into a coherent whole and demonstrates UMA’s independence from biological or computational
