Summary

Hey! Thanks for amazing work and this very useful project. I'm facing behavior where local macOS uv lock generates a different lock file from what is done on Linux.

My pyproject.toml file contains

[[tool.uv.index]]
name = "mycompany"
url = "https://mycompany-123.d.codeartifact.us-east-1.amazonaws.com/pypi/mycompany/simple/"
default = true
authenticate = "always"

and when executing uv lock on macOS, it contains entries like

[[package]]
name = "tomli"
version = "2.2.1"
source = { registry = "https://mycompany-123.d.codeartifact.us-east-1.amazonaws.com/pypi/mycompany/simple" }

However, when doing

uv sync --extra torch-gpu --locked --no-dev --no-install-project

during Docker build on Ubuntu 22.04 with same uv version, it fails because it tries to change the lock file. The diff -u showed this:

-source = { registry = "https://mycompany-123.d.codeartifact.us-east-1.amazonaws.com/pypi/mycompany/simple/" }
+source = { registry = "https://mycompany-123.d.codeartifact.us-east-1.amazonaws.com/pypi/mycompany/simple" }

During docker build, I have UV_INDEX_MYCOMPANY_USERNAME and UV_INDEX_MYCOMPANY_PASSWORD specified.

Do you have any idea what might have gone wrong here?
