spoiler alert: it doesn't check
i just never encountered this before, because it looks like most generators check for a 2 key and either invert it or reject it
it's not specified in either nip-04 or bip-340 except obliquely and not explicitly
you can't get around it, claude is wrong, the ECDH computation makes two different keys depending on whether it's an odd or even Y
