BTW, as far as I can see the overflow/underflow behavior never got

2) Andrei's book doesn't seem to mention the topic.
If it is specified somewhere please do tell. Whatever the behavior
should be (unspecified, modulus for unsigned integers, etc) there really
should be an official stance.
The official stance is, it's not an error. If we treated it as an error,
then it would be very costly to implement, every operation would have to
check for overflow. The CPU does not assist in this.
You can construct an "overflow-detecting" integer type that should be able
to do what you want.
