The states other than “valid” are what give this page authority. A verification page that can only ever confirm is a PDF with extra steps. Because this one can say lapsed or withdrawn and mean it, a gym owner has a reason to check rather than take a printout at face value.
It is also the reason renewal can be sold at all. A credential that quietly stays valid forever has no renewal to charge for. One that visibly lapses does.
