Device handoff — newest device wins

Swap devices, keep the run

A tablet dies. A phone gets too cold. You climb into a different machine. Whatever the reason, you can pick up your run on a new device without stopping — Snowmass uses a simple, predictable rule: newest device wins.

How it works

Open your run on a new phone or tablet and that device silently takes control. The old device drops to read-only automatically — it won't keep sending pings or claiming work. There's no "log out here before you log in there" dance and no risk of two devices fighting over one operator's identity.

Why "newest wins"

Only one device can be the live source of your position and your claims at a time. If two were both active, your dot would jump around and the swarm would get conflicting signals. By always trusting the most recent device, the handoff is instant and unambiguous — the one in your hand right now is the one in control.

What to watch for

If your old device shows read-only, that's expected — it means the handoff worked. Just make sure the device you actually want to use is the last one you opened the run on.

Why it matters

Hardware fails in the cold and mid-storm is the worst time to get locked out of your own run. Handoff means a dead battery is a thirty-second swap, not a call to the dispatcher and a gap in coverage.
