russell@unturf.com db92c9428a bullet3/three.js: CWE-407 findings ... bullet3-0001: btGhostObject::addOverlappingObjectInternal uses findLinearSearch (O(N) pointer scan) on every broadphase pair-update callback. With N objects overlapping a ghost, each tick is O(N²). Fix: btHashMap<btHashPtr,int> shadow index → O(1) add/remove. 250x at N=500. three-0001: NodeBuilder.addNode/addSequentialNode use Array.includes (O(N)) per node during shader build traversal → O(N²). StackNode.generate uses nodes.indexOf inside filter → O(N²). Fix: shadow with Set → O(1). 250x at N=500.		2026-03-30 09:25:29 -04:00
