digital it wasn't delivered in an update, or installed on any devices, but simply added to the GrapheneOS apps repository should users wish to install it.
From GrapheneOS Testing room:
since it can't be obtained from the Play Store yet, we've added a mirror of the Markup image editor app in the stock Pixel OS to our app repository.
it's a tiny app with no required permissions and provides nice image editing functionality, so many people want to use it on GrapheneOS, but there was no safe way for people to easily obtain it since it's not on the Play Store
we decided to mirror it to avoid people getting it from apkmirror and then not having updates for it
despite not requiring any permissions including not using internet access, updates still matter
several image editors including this one and the Windows equivalent for editing screenshots had a vulnerability for cropping where they left the old data past the end of the new file size, but people who manually installed it via apkmirror wouldn't have gotten that update, demonstrating the importance of providing a proper way to obtain it with automatic updates
