Extended Topological Quantum Field Theory (Part III): Computational Realization, Zeta Economics, and Invariant Governance

The first two papers in this series established the mathematical foundations and definitive stability proofs of Extended Topological Quantum Field Theory (DFT-TQFT). We proved that abstract infinite systems remain structurally secure, convergent, and well-founded under the strict boundaries of admissible morphisms. This third and final paper bridges these abstract mathematical structures into fully executable computational processes. We translate categorical functorial liftings into an executable state machine pipeline governed by a strict algorithmic Acceptance Function. Furthermore, we map these computational invariants onto real-world decentralized architectures, introducing Zeta-Regularized Tokenomics for infinite participation networks, Invariant-Based Governance for policy evolution, and Keyless Cryptographic Security derived intrinsically from topological footprints.
