Any of us can help log the changes by submitting revisions of the article to web.archive.org

With a fast-changing news story where vague/incomplete/conflicting details emerge in the first few hours it's not unreasonable for the first few revisions to be like that, and eventually gets fixed hours or a day later.

I think that’s what’s critical here. Post details and their sources to show that they are in flux. Don't write them as fact and then make secret edits.
