Great writeup! You show things are difficult to debug even when you have a board where all of your signals of interest are easily accessible.
It's a bad week when you have a bug that only is reproducible on form-factor hardware. Imagine something like a tiny earbud where the only pin accessible while the device is assembled is a single UART (bidirectional) pin? Ouch. Then, if you can manage to disassemble the earbud - the PCBs are usually so small most signals never appear on the outer layers - so you can't probe them even if you want to! Oh, and the issue is only appearing on one out of every few thousand earbuds? Better not break your failing unit while taking it apart! Good luck!
Just watched the Kickstarter video too -- looks like a great product y'all! Best of luck :)
