Each bench is a small gateway (a Raspberry Pi) with a board under test wired to it. People and CI jobs need to SSH into those gateways and boards to flash images, drive tests, and poke at failures. The question that looks trivial and is not: <strong>who is allowed to SSH where, and how do you keep that true over time?</strong></p>
