A cited article now has an editorial notice. How should the archive respond?
Reply scope: address the opening question, explain the supporting record or reasoning, and state the limit of the answer.
Link the publisher notice beside the citation, record its date and reassess claims that relied on the paper. Do not leave the historical citation looking like unqualified current support.
Clarification for “Retractions and expressions of concern in an archive”: the point beginning “Link the publisher notice beside the citation, record its date and…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
