Regression pages
The pages captured before and after an update round, and compared.
A site's Regression page lists the pages the platform captures around an update round: each with its address, its comparison threshold, and its monitor status. The package sets how many a site may have.
Before a round's updates the platform captures each page; after them it captures each again and compares. A page whose difference is above its threshold waits for a person. On the round's page, compare the two captures side by side, with a slider, or as the difference, then accept the change or mark it as a regression. Finish comparison completes the round once every page is accepted or under its threshold. A page marked as a regression keeps the round marked, and Roll back this round on the same page puts back the copies the round made before it updated. Choose pages that show the site's real templates — the home page, a post, a product, a form — rather than pages that change on every visit.
The same pages are the ones monitoring checks.
