+-- ============================================
+--
+-- The privacy settings table is now set up with:
+-- ✓ Table structure with all required columns
+-- ✓ Check constraints for enum validation
+-- ✓ Unique constraint on user_id
+-- ✓ Indexes for performance
+-- ✓ Automatic updated_at trigger
+-- ✓ Row Level Security policies
+-- ✓ Optional audit logging table
+-- ✓ Optional automatic default settings for new users
+--
+-- Next steps:
+-- 1. Verify the migration ran successfully
+-- 2. Test the API endpoints
+-- 3. Verify RLS policies work correctly
