checks_active
=============

.. py:function:: t3toolbox.safety.checks_active(*inputs)

   .. code-block:: python

      def checks_active(*inputs):


   True iff numerical precondition checks should run here: **safe mode AND not under a jax trace.**

   Pass the operand arrays/trees so tracing is detected; a check site computes its (possibly expensive)
   numerical condition only when this returns True::

       if safety.checks_active(frame.data):
           safety.require(frame.is_orthogonal(atol=safety.effective_rtol(frame.data)).all(), 'frame not orthogonal')
