What
A remote client can no longer read back your applied model, effort and advisor state or your settings-file errors. On a bridge connection (CLAUDE_CODE_ENVIRONMENT_KIND=bridge) the get_settings control request returns "get_settings is not available on this connection" instead of a settings snapshot. Local sessions still get the full snapshot.
Evidence
get_settings is not available on this connection
