Face a live electrical panel in a data center: put on your dielectric gloves, hard hat, and safety glasses, mark off the hazard zone, and use a voltage tester to locate the isolation point before you touch a single wire. Once it's confirmed safe, you'll lock out the circuit breaker and connect the new wire — the full troubleshoot-and-repair sequence, minus the real voltage.

SimGenie acts as a built-in lab assistant. A learner who gets stuck can ask for a hint by voice, and it adapts its guidance to what they are doing in the scene.
