"""Bazel modules.

`MODULE.bazel.lock` may change locally when `bazel` is executed. This means one
of:

1.  An input is changing, typically `MODULE.bazel` or `.bazelversion`.
    -   Running `bazel mod deps` provides a canonical update to
        `MODULE.bazel.lock`; include the changes.
    -   GitHub test actions may also identify platform-specific lockfile
        updates.
2.  The host platform hasn't yet been added to the lock file.
    -   Platforms tested with GitHub actions are kept up-to-date. Other
        platforms may fall out of sync due to `bazel` or dependency changes,
        and should be updated with a PR the same way a platform is added.
    -   Running `bazel mod deps` provides a canonical update to
        `MODULE.bazel.lock`; create a PR with those changes in order to include
        the host platform.

For updates, run `scripts/query_module_versions.py` to list the latest package
versions.
