"""Regression tests for the raft platform plugin's check_fn.

The raft platform adapter's ``check_raft_requirements()`` is registered as
the platform's ``check_fn``. This function is invoked on every
``load_gateway_config()`` call (dozens of times during normal gateway
operation). It must therefore be a *silent* predicate — returning True/False
without logging — otherwise every user without the ``raft`` CLI installed
gets their logs flooded with WARNING messages every few seconds.

See: https://github.com/NousResearch/hermes-agent/issues/49234
