What
When Claude Code checks the organization's fast-mode status, it now also detects whether the current login looks like a managed worker identity, such as one built from an org_service_name/code_agent_id pair or a session_worker role. If so, and fast mode isn't enabled, the status is reported with reason preference instead of the generic unknown.
Why
This gives a more accurate explanation for why fast mode is disabled for automated or service-style accounts, rather than lumping them in with genuinely unknown cases.
