Excellent. Now I not only have to check if the cited source actually says what the LLM claims, I should also verify if it made up the source itself.

The bug: "models made unrequested public uploads"

The explanation: "It seems likely that the citation-upload behavior originated as a way to get rewarded by flawed citation graders when there was no external source to cite."

The fix: none. Instead "We fixed the broken graders" despite that no such breakage had been identified.
