- TransformComponent TRS = local (relative to parent); cached world SRT composed hierarchically (parent pos/rot/scale, no matrix decomposition shear under non-uniform parent scale) - HierarchyComponent (parent + children, lazily attached); Scene:: SetParent (keepWorld, cycle-safe) / GetParent / IsDescendantOf / SetWorldPose (world->local inverse, used by physics writeback & gizmo) - UpdateTransforms: DFS from roots, recompose only dirty-or-dirty- ancestor subtrees (parents before children) - DestroyEntity: descendants buried with parent (UE cascade) - Serialization v2: optional Parent uuid key, two-pass relink on load - Hierarchy panel: tree view, drag-drop reparent / drop-to-root detach, Create Child / Detach context menu; Inspector shows parent name - Consumers moved to world-space reads: lights, camera pos, physics bodies/characters/joints/collider baking, gizmo, F-focus, AlignTo
