          The repository containing the spack manifest to install.
          By default, this is the caller model component repository, which will work for most use-cases.
          For example: ACCESS-NRI/access-test-component.

        default: ${{ inputs.spack-manifest-repository == github.repository && (github.event_name == 'pull_request' && github.event.pull_request.head.sha || github.sha) || '' }}
        description: |
          The branch, tag, or commit SHA of the inputs.spack-manifest-repository to use.
          For example: main, 2025.03.0, r23ij2o3.
