Two chains, one physical, one software, drawn the same on purpose. Click a node to see its blast radius. Close the strait to fail both chokepoints at once. Then declare the graph, keep it verified, and watch what the monitor could see all along.
Tip: nodes are focusable. Tab to one and press Enter to see its blast radius. Click the background to clear.
Illustrative. All data synthetic. Two teaching chains, drawn the same on purpose. Not a model of any real fuel network, vendor, registry, or system.
