Claude Code can now detect a specific 'bound_unattested' auth error to trigger device re-enrollment
What
A new internal check recognizes when an authentication error is specifically about an untrusted device that hasn't been attested (sub-reason bound_unattested). Recognizing this case is what lets Claude Code proactively kick off device re-enrollment or a relogin flow instead of just failing.
Why
This helps Claude Code respond to a specific device-trust problem automatically rather than surfacing it as a generic authentication failure.
