Summary

This warning appears when failing to set lower bounds on dependencies:

warning: The direct dependency `click` is unpinned. Consider setting a lower bound when using `--resolution lowest` to avoid using outdated versions.

This occurs when using --resolution lowest-direct, which could be misleading since the message implies --resolution lowest is being used.

Simple reproducer

1. uv init --lib
2. Add an unpinned dep; e.g. dependencies = ["click"]
3. Run uv export --resolution lowest-direct > requirements.txt
