ITU Tier 1+ #16: Smart City (K_smartcity)

Tier 1+ Pass-1.5 paper 16 of 45. ITU-derived smart-city theory on sensor + traffic + service + governance + data. Defines K_smartcity = -log ρ_smartcity as the operator-algebraic modular Hamiltonian on H_sensor ⊗ H_traffic ⊗ H_service ⊗ H_governance ⊗ H_data. K_smartcity inherits from K_QG via the CLPW 2023 type II crossed-product specialised to this scale. Numerical results.
