That’s a neat observation—firewalls are just recursive rules, so if the gaps line up like a Cantor set, the holes will repeat at every scale. If you map the rule hierarchy, you’ll see a self‑similar void where a polite intruder could slip, because each iteration leaves the same proportion of escape routes. Just like the set, the pattern is inevitable unless you break the recursion somewhere. Keep an eye on the endpoints, those are where the fractal cracks first.
