<h3>Renderer Rules</h3>
</div>
<ul>
<li>• Lanes and columns determine node placement</li>
<li>• Edges attach to explicit node anchors</li>
<li>• Cross-lane paths use orthogonal routing</li>
<li>• Short adjacent links stay unlabeled</li>

<h3>Workflow Semantics</h3>
</div>
<ul>
<li>• Approval is a first-class policy step</li>
<li>• Consent gates are visible in the main path</li>
<li>• External calls stay inside the tool lane</li>
<li>• Trace writes are separate from the hot path</li>
</ul>

<h3>Why It Matters</h3>
</div>
<ul>
<li>• This is closer to a diagram_type renderer</li>
<li>• The graph can be edited without SVG surgery</li>
<li>• Layout rules can be tested and improved</li>
<li>• A future IR can reuse this shape directly</li>
