<p>We have two sets of GitLab CI variables in our template configuration:<br>
Variables prefixed with _ sort to the top of the list, and are meant to be overridden by project maintainers for adhoc tests and general configuration.<br>
Variables without the prefix are meant to be updated centrally by the DA in these templates, and should not be overriden.</p>
<p>However, the UI allows maintainers access to both variables. </p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>File an upstream request with GitLab to designate certain variables as 'not overridable' </p>
