I unfortunately ruined the board for the demo here, but it is what it is. I wiped a surface mount diode off and cannot find it, not that I would know how to reattach it and in what orientation, so take it as a warning to be as careful as possible!!!
Also forgive the hideous state of this thing, I used a file to scrap the coating off to find tracings lol, a completely unnecessary step but it did lead me to thinking to dig thru the board.
