Wiki contributors use edit patrolling to make sure that a trusted contributor has looked at a newbie's edit, and thinks it's a good contribution. When there's an unpatrolled edit, that item has a red exclamation point in recent changes and watchlist. The experienced contributor can review the edit on the diff page or the oldid page, and click a link to signal they've marked it as patrolled. See below for example screenshots.
For Flow posts and edits made by users who need to be patrolled:
On the oldid page, put a link that says [ Mark this page as patrolled ]
On the diff page, put a link that says [ Mark as patrolled ]
Those link to an &action=markpatrolled link.
When you click that, the [ Mark as patrolled ] link disappears, and there's a temporary modal (mw.notify): "The change to Pagename has been marked as patrolled."

In grouped recent changes, the clickable timestamps should also be a link to the oldid page:
