 - Simplifies future imports: `import { BaseButton, BaseModal } from '../components/shared/index.js'`
 - Pattern ready for additional shared components
 
+**ChallongeTest.vue Refactoring:**
+- Replaced manual `loading`, `loadingMore`, `error` refs with three `useAsyncState` instances
+- Converted `testListTournaments()` to use `tournamentListState.execute()`
+- Converted `loadMoreTournaments()` to use `loadMoreState.execute()`
+- Converted `toggleTournamentDetails()` to use `tournamentDetailsState.execute()`
+- Removed `handleError()` function - errors now handled by useAsyncState
+- Updated `switchApiVersion()` to reset all async states
+- Result: Cleaner state management, consistent error handling pattern
+
 **Testing:**
-- All 79 existing tests continue to pass
+- All 91 existing tests continue to pass
 - Build verification successful (no syntax errors)
-- Ready for next phases
+- Ready for Phase 4: Feature Flags
