What
Claude Code can start a cloud session from a folder on your computer and keep that folder in sync. A cloud session is one that runs on remote servers rather than locally. Two things differ in how these sessions attach to your machine:
upload_onlysync consent no longer stops the session from being bound to this machine.- Binding refused for a folder cloud session means the session is archived and creation fails with a
device_unbounderror.
The sync process now also receives the ID of the machine the session is bound to.
Why
This changes what you see when a cloud session made from a local folder cannot attach to your computer: the session is archived and not created, instead of continuing unbound.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is not established what controls whether this folder sync feature is available at all.
