Regions with many nearby points keep subdividing. Regions with few or no points stay large. The tree adapts to the data: dense areas get fine-grained cells, sparse areas stay coarse. The split grid is predetermined (always at midpoints), but the tree only refines cells that need it. Sparse regions stay as single large nodes while dense regions subdivide deeply.
The guest runs in a separate virtual address space enforced by the CPU hardware. A bug in the guest kernel cannot access host memory because the hardware prevents it. The host kernel only sees the user-space process. The attack surface is the hypervisor and the Virtual Machine Monitor, both of which are orders of magnitude smaller than the full kernel surface that containers share.
