ah nvm, I see. You do bundle it all into a single `CheckResults`:

return CheckResults(
        [
            CheckResult(
                result.exit_code,
                stdout="",
                stderr="",
                partition_description=str(coarsened_target),
            )
            for result, coarsened_target in zip(results, coarsened_targets)
        ],
        checker_name="javac",
    )
