|OMG a crack! :'(|
- Filling the cracks with JBWeld: I was really surprised by this, as I thought the crack would continue to propagate anyway, but they swear it won't.
- Cutting off the corner: they say this should be fine, though less aesthetically pleasing due to the reduced thickness
I was way more comfortable with the second option, so I did that - it indeed doesn't look pretty, and I may still need a small doubler around that rivet hole to adjust the thickness, but I'm comfortable that the skin will stay in one piece now:

As if that weren't enough, as I was dimpling the pitot mount screw holes on the other skin, some cracks showed up on the #8 dimples:

so I had to file those down, which deforms the holes (but should be ok for screws):

I'll make a separate post about the wing wiring and electrical planning.
