E1401. Backend unreachable
Severity: ERROR. The SDK degrades to the cached bundle when one exists.
What happened
The SDK could not connect to api.controlzero.ai (or whatever
CONTROLZERO_API_URL points at). Tool calls will use the cached
policy bundle; new audit events buffer locally.
How to fix
Check curl -I https://api.controlzero.ai. If you're behind a
corporate proxy, set HTTPS_PROXY before launching your agent.
