Hi Hugo,

Sure, understood. I'd like to propose to use another word, as "origin" belong to the lexical field of "source", "ancestor" etc. and is misleading.

A better word for the text may be "revision" or "version". Maybe even better, we could avoid the construct of helping "recognize the origin of an answer" altogether. For example, instead of

we could just have

This affects the abstract and the introduction.
