A device's zero-campaign attestation key, once the app has created and
uploaded one.
The key is a device fact, like the USDID identity: it outlives the process
and is carried in the snapshot. A device that never uploaded one is a fresh
install. The library does not create or upload the key, and it does not send
x-meta-zca; modelling the token and its upload is tracked separately.
