Not a traditional reading list, but what I've personally read / watched that I felt was crucial in understanding ZK so far.

Also links to handcrafted walkthroughs that hopefully help others understand better.

This is the type of bug that keeps me awake at night. Wouldn't have spotted it. IMO the core issue isn't the rounding direction itself, but the impact of it when the total amount is really small. 1 wei vs 1e6/18 is negligible, but 1 wei vs 4 wei = 25% under / over estimation.
