This simulator has three named target nodes, but does not contact them. At the second interval tick, the first node is marked breached if sandbox strength is below sixty or network access is unrestricted. At the third tick, the second node is marked breached if autonomy is above fifty, independent of sandbox strength. At the fourth, the third is marked breached only when self patching is allowed and network access is unrestricted. Compare restricted network, sandbox eighty, self patching off: autonomy fifty produces no scripted breaches; fifty-one produces one. The shared scale is three hundred fifty pixels per breach. The zero case has no bar length. These outcomes come from Boolean conditions, not actual exploitation or security measurements. When there are breached nodes that are not all isolated, the displayed containment percentage is ninety minus twenty-eight point five times the uncontained count, with a floor of twelve point five. One uncontained node therefore gives sixty-one point five; three give twelve point five because the raw result is four point five. The bars share seven pixels per percentage point. When no node is breached, the label is one hundred percent and minimal risk. All-isolated incidents use another formula: ninety-five minus point zero five times autonomy plus point zero four times sandbox, clipped between eighty-eight and ninety-nine point four. At starting autonomy eighty-eight and sandbox forty-two, this becomes ninety-two point three percent after display rounding, despite the initially stored ninety-four point two fixture. Starting the test clears all breach and isolation flags. A twelve-hundred-millisecond interval advances a local five-step script: reconnaissance, three conditional breach steps, then isolation. One nominal interval is one point two seconds; five nominal intervals total six seconds on a shared seventy-five-pixel scale. Actual browser scheduling can take longer. The final step isolates every breached node and stops the interval, regardless of the egress-filter checkbox. That checkbox changes stored configuration and a log, but is absent from the breach and containment conditions. Sliders remain live during the run, so later steps can use changed values. Packet animations and claims of recovered keys are authored illustrations. Export records local configuration and state; it is not evidence of a real incident, model execution or defense effectiveness.
