Attack tree (cybersec)

Native attack-tree diagrams for threat modelling and security review. Declare a root goal, then sub-goals as AND (all-of) or OR (any-of) refinements. Leaf nodes carry cost / skill / detection estimates that propagate up the tree. Critical paths render in red. Compatible with STRIDE / DREAD workflows.
