Does Dispatch find problems on its own?

Yes. Dispatch re-crawls every governed page on a schedule you set per site, keeps a score history for each page, and opens a finding when a check that used to pass now fails, a score drops, a page stops answering, or a page falls out of the sitemap. Each finding carries a drafted change request an agent can execute, so the work arrives already written. Findings close on their own when the check passes again. This is in production today.
