Safety-critical cyber-physical systems must evolve---through adaptation and post-deployment updates---without forfeiting the guarantees on which their certification rests. Yet digital-twin (DT)--based model-based systems engineering (MBSE) lacks a formal mechanism for preserving correctness as the physical twin (PT) an...

This fragmen...
