Setup-token grants don't set ExpiresAt on the credential, leaving it as the zero time.Time. WriteCredentialsFile called UnixMilli() on this, producing -62135596800000 (year 0001) in .credentials.json. Claude Code read that as an expired credential, showing "not logged in" and "API Usage Billing" in the status line instead of recognizing the session. Use a 1-year-ahead timestamp when ExpiresAt is zero. Setup-tokens are long-lived and the placeholder credential just needs to look valid locally — the real token is injected by the proxy at the network layer.
