console.log('The refactor successfully:');
console.log('1. Separated concerns into logical functions');
console.log('2. Made each function have a clear, single purpose');
console.log('3. Improved readability and maintainability');
console.log('4. Preserved all debug logging');
console.log('5. Maintained 100% backward compatibility');
