We could create a new qualifier like ''contradicted by'' or ''disputed by''. The sourcs are a problem though as we can source only the totality of a claim, not only a qualifier of this claim, so we would have to source all the sources for the claim and it's disputation sources in the source without order..

Since attributions in arts, history, composition and many other
field are uncertain, doubtful, questioned, or contradicted
without an alternative at significant rates - in the
10% magnitude if you go back in time a bit - we ought to have
them.

Contradictions are indeed a new type of statement, because they
have to refer to the staements they disclaim.
