Operator briefing
A first website has no old URLs to preserve. A replacement adds URL and migration checks. A domain move also adds old-domain certificate and Change of Address steps.
A checked box should refer to a visible result: a response header, a received form message, a valid certificate or a Search Console screen. Keep screenshots or command output with the release record when the change is important.
Nothing is transmitted. If you enable remembering, completed and not-applicable marks are stored in localStorage in this browser and can be cleared at any time.
