Unclear Whether this is controlled by the remote switch it appears to be is not confirmed.
What
Cloud file sync copies your project files into a cloud session started with --cloud. Sync now signs the synced files with a key tied to your computer. If that cannot be set up, sync stops with a message explaining why. This happens when the cloud did not register your computer as a device for the session, or its device key could not be read. The message suggests running without sync: CLAUDE_CODE_DIR_SYNC_ENGINE=none claude --cloud.
This part of file sync is off unless it is switched on remotely.
Why
When device registration fails, sync now stops rather than sending unsigned files. The message gives you a way to keep working without sync.
The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
