Kortz Center Heist - Rooftop Entry - Solo - Undetected (No Damage)

Half pacifist, no one inside the building is killed. I really wanted to do this fully pacifist since it was an option, but the stun gun isn't silent during the escape so guards will hear you fire it or melee with it. After my last run went bad when I meleed a guard and two random guards on the ground floor heard it and turned around, I ditched the idea and just used a silenced weapon until I entered the gallery. Going full pacifist doesn't prevent the silent alarm from going off either, and the pilot on the roof will always kill two guards off-screen so this escape method might be impossible to run pacifist anyways. In general, it seems like there's no reason to knock out the guards. As you can see, when I get into the vault they get back up and I need to knock out half of them again to get out. I thought it was fun but it's just extra difficulty for no added benefit.
