I was checking guidance on where to put footnote or endnote reference characters relative to punctuation and found a really clear answer for everything except an ellipsis.
It's pretty unlikely and rare that you might want to footnote or endnote the end of a snippet of text that ends in an ellipsis, which is probably why I can't find any information on it. But it's possible.
Supposing there was such a case, should it be like this:
However, there might be other reasons for such varied evidence. One study has even found strong evidence of conflicts of interest emerging in some cases...[3] It is beyond the scope of this paper to speculate on whether that is what happened here.

Case for the former (note reference character after the ellipsis): It's consistent with commas, full stops/periods, etc, and strictly follows the Chicago Manual rule "note reference numbers in the text should follow any punctuation marks except the dash". (although I believe the Chicago manual has some less-than-usual guidance on ellipsis being widely spaced)
Case for the latter (note reference character before the ellipsis): The other way looks horrible without serious kerning. Also, to me, an ellipsis feels more like a dash than a comma or full stop/period... (not sure how to qualify that)
