What is the role of Wikipedia talk pages in page management?

Every Wikipedia article has a corresponding Talk page where editors discuss the article rather than edit it. For our work on client pages, the Talk page is not optional and it is not a workaround – it is the entire interface. The disclosed-COI editing model that Wikipedia accepts under WP:PAID requires that we propose changes there with reliable secondary sources, identify ourselves and our client relationship in the user account, and let independent community editors evaluate and implement. Done well, Talk-page work produces a transparent paper trail that strengthens the article’s integrity rather than threatening it. Done badly – through direct edits to the article, undisclosed accounts, or argumentative tone – it produces reverts, sanctions, and lasting hostility from the editor community that follows the page for years.
