Has anyone mapped the outside-install screen states?

Concrete screen-state checklist for Android outside installs.

I am looking for a cleaner checklist for Android outside-install screens. The states I would separate are: verified developer, unverified developer, source permission not granted, cooldown pending, cooldown complete, update over existing package, and revoke exception. The hard part is not the red warning. It is making the owner path legible without helping a scammer coach someone through it. If you have seen a good screen flow, the useful detail is what it names on the final confirmation page.
