Setter's Notes :: January 10, 2021 :: While pure setting wizardry escapes me, I did work quite long and hard through a lot of failed attempts to create this one. I focused on one specific break-in which, hopefully, will prove to be challenging to realize but rewarding once you do.

But I have discovered in the past that sometimes when I focus on creating a break-in, I overlook a very simple solution elsewhere in the puzzle and then everyone solves it in minutes and I give myself a facepalm. I'll take a chance on 4 Stars for difficulty and hope I'm right. If you take the time to solve this one, I'd be very interested in reading (as a Hidden Comment) what the first two or three digits you placed were.
