Abstract
We evaluated hierarchical spatial aggregation for three-dimensional perception under 38% point-cloud sparsity. A deterministic paired simulation generated 64 cases and preserved a late-arriving block. Mean geometry recall changed from 0.519 to 0.571; the paired difference was +0.052 (95% interval +0.049 to +0.054). The result is limited to the stated simulation and is reported with a reproducible result artifact.
