A closure-based operating system architecture defines stabilized system identity within a structured memory architecture maintaining structural expressions and intrinsic structural relations. A closure stabilization component forms closure entities representing structurally stabilized system states, each closure entity including a closure signature defining identity continuity across structural evolution. Closure entities are structurally constituted within the structured memory architecture and constitute operating-system-level identity distinct from transient runtime states. Execution participation is grounded in structurally admissible closure entities rather than procedural state transitions or rule-based control. Identity continuity arises from intrinsic structural relations and structural invariants preserved through closure signatures, enabling admissible execution, distributed participation, suspension, and migration while maintaining stabilized system identity independent of execution-driven mechanisms. The architecture thereby establishes a structural identity ontology for operating-system-level system states independent of execution-driven state transitions.
