Using the WikiProject filters, users will see items in the first page of results that were already checked using the on-wiki EranBot interface. Copy Patrol is displaying every entry from the database, but we don't currently have a way to mark items that have already been checked, so we'll be displaying a lot of "open cases" that have already been triaged.

We need a way to mark items that have been triaged through the EranBot interface as closed.

Danny's probably-stupid suggestion is to have a human (ie Danny) go through all of the old archive pages from May 2016 back, and make a list of the cases that are a) not triaged and b) not redlinks. There actually aren't very many of those still-open cases. Then we use that list as a whitelist, and automatically mark everything else from May 2016 back as triaged.

Is there a less stupid way to do this?

Note: We can discount the really old cases from this; see T138317: Filter out all cases before June 20, 2016.
