print_section "Manual Testing Checklist"
echo "✅ Manual Tests to Perform:"
echo ""
echo "1. Chat Functionality:"
echo "   - Create a new chat session"
echo "   - Send multiple messages"
echo "   - Refresh the page"
echo "   - Verify messages persist"
echo ""
echo "2. Settings Persistence:"
echo "   - Change app settings"
echo "   - Refresh the page"
echo "   - Verify settings persist"
echo ""
echo "3. Cross-tab Sync:"
echo "   - Open app in multiple tabs"
echo "   - Make changes in one tab"
echo "   - Verify changes appear in other tabs"
echo ""
echo "4. Storage Fallback:"
echo "   - Disable IndexedDB in browser settings"
echo "   - Refresh the page"
echo "   - Verify app still works with localStorage"
echo ""

print_section "Expected Results"
echo "✅ Success Indicators:"
echo "   - No console errors related to storage"
echo "   - Chat messages persist across page refreshes"
echo "   - IndexedDB health check returns { indexedDB: true, localStorage: true }"
echo "   - Store integrity validation returns empty issues array"
echo "   - All store keys have valid data structure"
echo ""
echo "❌ Failure Indicators:"
echo "   - 'skip setItem' warnings in console"
echo "   - Messages lost after page refresh"
echo "   - Health check shows IndexedDB: false"
echo "   - Store integrity issues found"
echo "   - JSON parse errors in console"
echo ""

print_section "Troubleshooting"
echo "🔧 Common Issues & Solutions:"
echo ""
echo "Issue: 'skip setItem' warnings"
echo "Solution: Fixed with improved hydration logic"
echo ""
echo "Issue: Data not persisting"
echo "Solution: Check _hasHydrated flag and storage availability"
echo ""
echo "Issue: IndexedDB unavailable"
echo "Solution: App should fallback to localStorage automatically"
echo ""
echo "Issue: Corrupted data"
echo "Solution: Use debugStorage.clearStore(StoreKey.Chat) to reset"
