+- `src/uix/eidos/component-api-contract.test.ts` ahora tambien valida que los
+  miembros declarados en cada `XxxNamespace` coincidan con las asignaciones
+  explicitas del barrel (`Tabs.Trigger = Trigger`, etc.).
+- Esto cierra el hueco que dejaba el cast `const Tabs = TabsRoot as
+  TabsNamespace`: TypeScript no detecta una asignacion olvidada despues del
+  cast, pero la guardia estatica si.
+- Validacion: `npx vitest run src/uix/eidos/component-api-contract.test.ts`
+  -> 3 tests OK; `npm run check` -> 0 errores, 0 warnings.
