A system's world model is sensing projected over a volume. A mesh resolves it into three states — occupied, empty, and the unknown behind barriers. Toggle single ↔ mesh and watch the unknown close. Drag to orbit.

Perceive the whole, not the self. A single sensor is blind behind every occluder; the mesh sees each shadow from another node and drives the unknown toward zero.
