Split traffic. Override by country.

Route groups

Routes without a country form the required default group. Country-specific routes form an override group for that ISO 3166-1 alpha-2 country.

• ✓Every group must total exactly 100.
• ✓A default group is always required.
• ✓A country group is selected only when at least one active matching route exists.
• ✓Otherwise the resolver falls back to the default group.
• ✓A stable visitor hash keeps weighted selection deterministic when available.
