After geometry.partition cuts a body, the body is its cells: a projection plan of the whole body
could not open it and failed with "no body `Base` (open a design first)". It now names the cells
and says to plan and apply a cell (mesh.plan {"body": "Base/a"}) or delete the partitions. Tests
cover a design opened directly and a saved model opened again, partitioned after opening.
