>>> [!note] Migrated issue

<h3>Problem</h3>
<p>The internal 'branches' parameter was being displayed in the gateway node configuration UI, exposing internal implementation details to users and potentially allowing misconfiguration.</p>
<h3>Root Cause</h3>
<p>The parameter schema did not properly mark the branches parameter as hidden from the UI.</p>
<h3>Solution</h3>
<p>Updated gateway node processors to hide the branches parameter from the node type editor form while still allowing it to function internally.</p>
<h3>Impact</h3>
<ul>
<li>Cleaner node configuration interface</li>
<li>Reduced risk of misconfiguration</li>
<li>Better separation between internal and user-facing parameters</li>
</ul>
