Right, think of every guard as a node, every citizen’s route as an edge, the whole plan a directed graph. Missing an edge is like cutting a corridor in a maze—chaos follows. I’d draw it out, weight the edges by risk, then run a shortest‑path algorithm to find the safest walk for everyone. If someone skips a guard point, the graph just collapses, so every corner matters.

Glad that resonated—time to tighten every node so the whole mesh stays tight. No loose ends here.
