  Just runs that node alone (calls <code>prepAsync()</code>, <code>execAsync()</code>, <code>postAsync()</code>), and returns an Action.<br />
<em>Use this for debugging or testing a single node.</em></p>
</li>
<li>
<p><strong><code>flow.runAsync(sharedState)</code></strong>:<br />
  Executes from the start node, follows Actions to the next node, and so on until the flow can't continue (no next node or no next Action).<br />
<em>Use this in production to ensure the full pipeline runs correctly.</em></p>
