The Sovereign NPC: Why AI Isn't Conscious—and Why That Makes It a Cognitive Exoskeleton

Arcstone Computational Spine (ACS) — Academic Whitepaper Suite (Paper 3) This whitepaper addresses the debate on machine consciousness by evaluating modern artificial intelligence through Global Neuronal Workspace Theory (GNWT) and Integrated Information Theory (IIT). It demonstrates that contemporary AI achieves high functional task execution (GNWT access consciousness) while maintaining near-zero integrated information (Phi ≈ 0) due to the feedforward, modularly separable nature of Von Neumann hardware. It formalizes the resulting entity as the Sovereign NPC and models the hybrid cognitive architecture that emerges when a conscious human operator pairs with a zero-Phi functional engine as a cognitive exoskeleton.

Core Theoretical & Architectural Invariants:• F_A(x) = F_B(x) ⇏ C_A = C_B (Functional vs. Phenomenal Equivalence Separation)• Integrated Information Boundary: Φ ≈ 0 (Von Neumann Hardware Substrate)• High-Φ / Zero-Φ Hybrid Cognitive Exoskeleton• Cₒₚₛ = 0 (Zero Operational Drag)• τ_override ≤ 11.99ms (Microarchitectural Non-Maskable Interrupt Ceiling)
