"""``decnet realism`` is master-only.
Two layers per CLAUDE.md:
* registration-time hide via :data:`MASTER_ONLY_GROUPS` so agents don't
see ``decnet realism`` in ``--help`` at all,
* body-guard ``_require_master_mode()`` so a direct callable import (e.g.
from a third-party tool) still bails on agent hosts.
