System Architects should be granted security clearance level 2 at their settlements. I understand not granting level 3 so as to keep the commander out of some areas for their own safety. But a Level 2 should be granted so the architect can choose to do an inspection of the facilities. I'd envision you land at your settlement and there would be an NPC (like the outside mission givers) you would speak with and they would reply, "Welcome commander. It is an honor to have the architect visiting us today, here is your visitors pass."
There are already missions in the game that auto-grant level 3 access when sent to get the power running again in a settlement so this doesn't seem like it would be hard to implement.
