Cannot override dependency metadata of source dependency

[toslunar]

Summary

To reproduce, uv sync at a/ with the files below causes

  × No solution found when resolving dependencies:
  ╰─▶ Because only b==0.1.0 is available and b==0.1.0 depends on numpy<2, we can conclude that all versions of b
      depend on numpy<2.
      And because your project depends on b and numpy>=2, we can conclude that your project's requirements are
      unsatisfiable.

a/pyproject.toml

[project]
name = "a"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["b", "numpy>=2"]

[build-system]
requires = ["setuptools"]
build-backend = "setuptools.build_meta"

[tool.uv.sources]
b = { path = "../b", editable = true }

[[tool.uv.dependency-metadata]]
name = "b"
requires-dist = ["numpy"]

a/src/a.py

...

b/pyproject.toml

[project]
name = "b"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["numpy<2"]

[build-system]
requires = ["setuptools"]
build-backend = "setuptools.build_meta"

b/src/b.py

Note that for PyPI dependency we can override requires-dist (numpy<1.29.0,>=1.22.4 in scipy==1.12.0) by

c/pyproject.toml

[project]
name = "c"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["scipy==1.12.0", "numpy>=2"]

[[tool.uv.dependency-metadata]]
name = "scipy"
requires-dist = ["numpy"]
