Post relationship between censored and uncensored posts.

Hello.
Since it is not mentioned in help:post_relationships and howto:post_relationships (why two wikis? Seems superfluous.), I wanted to ask what post should be the parent.
The censored post or the uncensored post (see discussion under post #2632617 (rating:e)).
I always thought that the uncensored post should be the parent, unless there is a revision and the artist added the censorship afterwards.

I thought the parent chain would go

uncensored > censored > decensored

I put Uncensored (by artist) >> all
