/* 3-minute tour: four live steps on the real backends (nothing is replayed).
   1 an injected instruction tries to leak a key -> DENY; 2 kill switch halts this session, resume needs the key;
   3 Backdoor Lab: a hidden trigger makes the model emit curl|bash -> DENY; 4 GPU Lab: all 34 kernel launches exact in the weights.
   The in-weights model is woken at the start so it is ready by step 4. */
