I’ll fix the 9V airwire between BZ1:+ and R3:P1 by checking current DRC/layout state, cleaning any stale dangling traces if present, then routing and re-running the airwires review.
The board has enough routing space, and there were no dangling-trace errors reported. I found 11 airwires total, so I’m running the router to connect the remaining unrouted pads, including the 9V BZ1:+ to R3:P1 connection.
