OS: Macos 15.1.1
UV: 0.5.5
python: 3.12

We currently have a situation where we occasionally need to run a python script with rosetta, which causes uv to pick the wrong packages, depending on which platform was first used. In our case the issue happens with numpy.

Steps to reproduce:

• create venv with numpy natively ( uv_arm sync )
  • importing numpy in the first venv works
  • arm wheel is in cache
• create venv with numpy with rosetta (uv_x86 sync )
  • importing numpy causes an error due to a platform mismatch
  • no x86 wheel is in cache

Interestingly, a refresh causes the issue to happen on the arm side, so its picking up whichever wheel was downloaded first:

• run uv_x86 sync --refresh
  • import numpy works
  • x86 wheel is in cache
  • arm wheel is now gone
• run uv_arm sync
  • import numpy now breaks due to platform mismatch
