This got merged this morning:

[https://github.com/discourse/discourse-ai/pull/1108](https://github.com/discourse/discourse-ai/pull/1108)

The backfill job now uses `last_posted_at` instead of `created_at`. I also made changes to the logic to determine if a summary is outdated by checking if any of the posts’ `last_revised_at` is newer than the summary, to take edits into account.
