Security Patrol Predictability Simulator

A perfectly repeating patrol route is a rehearsed weakness: watch it once or twice and the exact moment of maximum unguarded time at any checkpoint becomes knowable in advance. This simulator puts a patrol robot on a six-checkpoint facility loop under two strategies — a fixed route that repeats the same order and timing every round, and a randomized patrol that visits the same checkpoints but shuffles the order and dwell time each round. Target a checkpoint, watch the "predicted next visit" countdown sharpen (or fail to sharpen) as rounds accumulate, then fire intrusion attempts — manually or automatically — and compare how the success rate of the exact same exploit strategy diverges between the two scheduling policies over many rounds.
