The tree is rebuilt every frame. For scenes of this scale, quadtree construction is fast enough to rebuild from scratch each frame, though larger simulations may benefit from incremental updates. Each particle queries its neighborhood for potential collisions, typically checking only 5 to 15 candidates instead of all 40. Red highlights indicate colliding pairs.

We even tried building hierarchies with 2-3 levels, but the number of shortcuts grew too fast for higher levels if we generated a full graph inside each cluster.
Prototype pollution defense: One test patches Object.prototype.then to intercept promise resolutions, then verifies that pipeTo() and tee() operations don't leak internal values through the prototype chain. This tests a security property that only exists because the spec's promise-heavy internals create an attack surface.
