"""test_xros.py — end-to-end test of the spatial shell + world-state service.

Two layers:
  1. Unit: drive the SpatialShell directly against a WorldState and assert
     the world mutates correctly.
  2. Integration: start the real WebSocket server, connect a client, run
     shell commands over the wire, and confirm a second client observes the
     world changes (the DiOS "single shared resource" claim).

Run:  python test_xros.py
