Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: uv.lock

Command failed: uv lock --upgrade-package mypy
Using CPython 3.14.7 interpreter at: /opt/containerbase/tools/python/3.14.7/bin/python3
  × No solution found when resolving dependencies for split (markers:
  │ python_full_version > '3.9' and python_full_version < '3.10'):
  ╰─▶ Because only the following versions of mypy{python_full_version <
      '3.10'} are available:
          mypy{python_full_version < '3.10'}<=1.20.2
          mypy{python_full_version < '3.10'}>1.21
      and the requested Python version (>=3.9, <4.0) does not satisfy
      Python>=3.10, we can conclude that mypy{python_full_version <
      '3.10'}>=1.20.2,<1.21 cannot be used.
      And because descope:types depends on mypy{python_full_version <
      '3.10'}>=1.20.2,<1.21 and your project requires descope:types, we can
      conclude that your project's requirements are unsatisfiable.

hint: While the active Python version is 3.14, the resolution failed for other Python versions supported by your project. Consider limiting your project's supported Python versions using `requires-python`.
