Research direction

Start with the torch-backed xp.minimum, xp.maximum, and xp.copysign entry points shown in the issue, then compare their scalar handling with the 2024.12 Array API standard. Check the related binary functions for the same mismatch; done means scalar arguments work in either position without the reported TypeErrors.

Written by the indexing model from the issue text.

Description

blocked by upstream

Per the 2024.12 standard, these should work, but don't:

from array_api_compat import torch as xp
xp.minimum(xp.asarray(1), 2)  # TypeError: minimum(): argument 'other' (position 2) must be Tensor, not int
xp.minimum(2, xp.asarray(1))  # TypeError: minimum(): argument 'input' (position 1) must be Tensor, not int
xp.copysign(xp.asarray(1.), 2)  # OK
xp.copysign(2, xp.asarray(1.))
# TypeError: copysign() received an invalid combination of arguments - got (int, Tensor), but expected one of:
#  * (Tensor input, Tensor other, *, Tensor out = None)
#  * (Tensor input, Number other, *, Tensor out = None)

Looks like maximum also has trouble. Haven't checked the rest of the functions that now accept scalars, but I assume others may have trouble.
