ReadonlyfollowReadonlyopenThe profile's "Message" button: the 1:1 thread opened with the profile user (the message_button source).
ReadonlyopenThe profile's "Reels" tab: the profile owner's clips (ClipsProfileQuery), whose items open the reels viewer.
ReadonlyscrollThe person scrolls the media grid: the next page of tiles (the page after the visit's first).
The profile's actions. Written out so this action's inference does not make the definition circular: the suggested-user item's edge leads back to this screen, and a
typeof profileItemsin an inferred action type would close the loop. The annotation is checked against the implementation, so an itementerthat starts failing or needing a service fails this type.
