The only documentation I can find for `.bazelversion` is in https://github.com/bazelbuild/bazelisk/blob/master/README.md. However, `bazel` will error out if it doesn't match the `.bazelversion`. For example: ``` ╚╡/usr/bin/bazel build :all ERROR: The project you're trying to build requires Bazel 7.3.0 (specified in [elided]/carbon-lang/.bazelversion), but it wasn't found in /usr/bin. ``` Switching to this because the `MODULE.bazel` requires tighter version pinning in order to avoid churn, and this should help catch mistakes early. In `MODULE.bazel`, demote mention of the version issue because it should only really occur now when the version is being deliberately changed, so the connection should be more apparent.

`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.
