Verified milestones so far: Jev can leave the Player's House, cross Pallet Town, deliver itself through Route 1 (fighting and winning any wild encounters along the way), and reach Viridian City. Further legs of the journey (Oak's Parcel, the first Gym) aren't built yet — the walk currently ends the run once it reaches Viridian City.
