[Spoiler] Which ending is canon?

[Pyzaro]

Hi,

I'm a bit lost, there are 2 endings and 2 DLCs following thoses endings but which one is canon? Did the devs clarified the situation?

I guess we'll have the answer with the 2 last DLCs or Atomic Heart 2 but i was wondering if the devs communicated something or not?
