A saved Prefab has speed = 3 in the Inspector. The script initializer changes from 3 to 5. What happens to that existing Prefab value?

1. It normally remains 3 because the serialized asset value takes precedence.
2. It always becomes 5 at the next compilation.
3. Unity averages the two values and stores 4.
4. The component is removed because its schema changed.
