  <dt>Field Reference</dt>
  <dd>
    <ul>
      <li>
        <span class="param">Diff</span>
        A diff structure between the submitted job and the server side version.
        The top-level object is a Job Diff which contains Task Group Diffs,
        which in turn contain Task Diffs. Each of these objects then has Object
        and Field Diff structures embedded.
      </li>
      <li>
        <span class="param">NextPeriodicLaunch</span>
        If the job being planned is periodic, this field will include the next
        launch time for the job.
      </li>
      <li>
        <span class="param">CreatedEvals</span>
        A set of evaluations that were created as a result of the dry-run. These
        evaluations can signify a follow-up rolling update evaluation or a
        blocked evaluation.
      </li>
      <li>
        <span class="param">JobModifyIndex</span>
        The JobModifyIndex of the server side version of this job.
      </li>
      <li>
        <span class="param">FailedTGAllocs</span>
        A set of metrics to understand any allocation failures that occurred for
        the Task Group.
      </li>
      <li>
        <span class="param">Annotations</span>
        Annotations include the DesiredTGUpdates, which tracks what the
        scheduler would do given enough resources for each Task Group.
      </li>

    even if it violates the job's
    [`prohibit_overlap`](/docs/job-specification/periodic.html#prohibit_overlap) settings. As
    such, this should be only used to immediately run a periodic job.
