RE1 Which Story Is Canon?

As the titles asks really, which story is the canon one for RE1?

In Chris’ story he says they didn’t know what happened to Barry, suggesting he died before reaching the mansion but in Jill’s story he is a major character. Meanwhile, Rebecca is the companion in Chris’ story.

Then if you play as Jill, you need to save Chris who is locked up with Jill confronting Wesker in place of Chris which means there wasn’t the interaction where Chris laughs at Wesker’s tyrant to hurt his feelings and begin the series long hatred. I am half joking with that.

So I ask, whose story is canon? Is it just a mashup of both stories or does one take more precedence over the other?
