The Quantum City: Self-Healing Networks, Interoperable Digital Twins, and the Architecture Decisions That Reverb With Eternity

Whitepaper on reality-first, sovereign, quantum-safe infrastructure. Reframes the design question as reachability under partition (Ukraine wartime networks). Empirical anchor: Altiostar/Rakuten Shibuya Open RAN self-healing (75 cells, 12.8M handover attempts, ~84 to ~92 percent handover success). Method via SMILE (Sustainable Methodology for Interoperable Lifecycle Enablement); inquiry logic via Rackham SPIN; maturity via NUDEDA extending Weill and Broadbent. Covers self-healing economics, workforce and robot knowledge transfer, the reality-capture stack, post-quantum cryptography, Minimal Interoperability Mechanisms, and a practitioner action set. Falsifier: the partition test.
