How to understand which change state is occured?

Hi,
First of all, thanks for the excellent work you've done. The thing that I didn't understand, there is no mapping file that indicates the change (for ex. add, move, remove etc.). How the program understands the issue?

The labelled caption can indicate the change type. For example, 'a house is built' indicates 'add'.
