The secret is to test every aspect of the problem. Then, you have to go to GPT or Stack and figure out .name even exists. Not a level 8, but curcial stuff to learn

So clever!

This was brilliant

Approved.

Thanks. Sorry for not approving it yet, I need to solve it first :D

Agreed.
Fixed it.

Yes, they shouldn't be in the setup code.
I removed them

Why include those two lines in solution set up:

%define HALF  0.5
%define TWO   2.0

?

Thank you for pointing this out.
I also added a comment line regarding the returned value and removed
useless remaining pieces of code (movsd xmm5, xmm0).

Since xmm0 holds the first argument, I think xorps xmm0, xmm0 should be removed from solution set up. This is different from katas involving integers, where rax always hold the result but can never be an argument at the same time, so it's a common practice to empty it first, and however it cannot have a bad incidence. A beginner could be confused. I would also add a comment line stating that the result must be stored in xmm0 (that's what is done in most existing katas).
