Heres my opinion.
The tracklist was
manipulated by blurryface
The reason its called the breach tour is because blurryface has breached and changed the setlist and controlling the band similar to when the bishops controlled them during the icy era
My reasoning for believing this was the setlist and tour vibe of the breach tour was giving VERY blurryface vibes, they also missed out alot of important songs like car radio, holding onto you, Mulberry street
They also played roughly 7-8 blurryface songs yet only 3 clancy songs and 5 breach songs (combinded makes 8 songs for clancy breach) which considering this is branded as clancy breach you would think this was heavily focused on breach and clancy songs
Compared to clancy tour with 10 clancy tracks and 6 blurryface tracks, you can see that this tour was heavily blurryfaced focused
If you also compare last tours setlist and this setlist you will see that alot of the joy and whimsical songs were removed like mulberry, this is the first tour since sai i think that they havent done mulberry, and also vessel was ignored this tour with only 2 songs from vessel compared to 4 from last era, vessel is their last non lore related album
My theory is this isnt breach tour in the sense that its a tour for their album breach, but rather the term clancy tour breach refers to blurryface breaching/taking over the clancy tour and manipulating it which also ties in with the “is this your hero” posters that depict clancy as evil
