Syntax
public class HudElementTreeOrderTests
Remarks

The permutation invariant is the one thing every other test — and every caller — depends on: a tool that iterates Solve(IReadOnlyList<Node>)'s result to draw a row per element would silently drop or duplicate rows the moment that invariant broke, which is a far worse failure than a wrong indent. Solve_RandomlyShapedStructures_AlwaysReturnsAPermutation() hammers it across many shapes, including the malformed ones (dangling parents, cycles) the solver exists to survive without losing a row.
