Retrospective governance is deeper and farther than ordinary litigation governance, otherwise it can't bear the more primitive concept of retrospective governance. This concept must have a more fundamental meaning and be closer to the real source of the problem. It can be said that traceability governance is a deeper social problem excavation and a deeper social governance method. Therefore, the source and cause of action are not only closely related to litigation, but also a deep governance problem. The two can't be equated, so it is safer to distinguish them and use them in their respective contexts.

In a sense, all the sources of complaints are also a kind of traceability, and there is a problem of tracing the source of the problem. The source of the problem is more closely related to litigation, so it can be directly expressed by the source of litigation.
