Preserve the article and relevant evidence
Record the URL, headline, author, publication date and the paragraph in question. Keep a dated copy or screenshot for your own records where appropriate, and gather primary documents or authoritative sources that support the correction. Avoid circulating sensitive information more widely than necessary. If the issue concerns a changed legal or regulatory status, identify the relevant official record and date. The purpose is to make the factual question clear, not to overwhelm the editor with unrelated documents.
