IIRC, there is one single bodge wire in there from where I did compromise the matrix, but I cannot stress how simplistic this PCB design was. It is holes for switches, holes for diodes, holes to string it over to the microcontroller dev board, and traces connecting them all. My second one is slightly more ambitious, allowing a couple of layout choices, Alps or MX, and has a designated spot to solder a specific MCU. That one requires two bodge wires because I screwed up the traces a little. If I do a third, I will know to make sure every trace is assigned to a “subnet” before I tell KiCAD to clean things up.
I mean, it helped that I knew the designer, LOL.
