Every existing job runs in a container. Docker masks /sys/devices/virtual/powercap there and gives no GPU, so the energy crates' hardware tests only ever took their "unavailable, and the oracle agrees" branch. This job runs on `linux-hw`, a host executor on jetson-hub. It runs as an unprivileged user (no sudo, no docker) that can read powercap and open /dev/nvidia*, on an Intel i9-13900H with package-0, a core sub-zone, psys and an mmio package, and an RTX 4050 Laptop GPU. It runs jcp-energy, eoc-meter, sandbox-meter, sandbox-exec-microvm, proof-cascade and jouleclaw-energy, with their NVML features on. Each step fails unless the live path ran: - RAPL: the oracle's package-only bracket was printed; - NVML: the GPU was seen. The source is fetched with plain git (the host has no Node), and the step checks it got the commit the run is for. Target dirs persist in the runner's home between runs.
