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: pyproject.toml

Artifact update for types-grpcio resolved to version 1.0.0.20260614, which is a pending version that has not yet passed the Minimum Release Age threshold.
Renovate was attempting to update to 1.0.0.20260607
This is (likely) not a bug in Renovate, but due to the way your project pins dependencies, _and_ how Renovate calls your package manager to update them.
Until Renovate supports specifying an exact update to your package manager (https://github.com/renovatebot/renovate/issues/41624), it is recommended to directly pin your dependencies (with `rangeStrategy=pin` for apps, or `rangeStrategy=widen` for libraries)
