UT3Tangent.validate
===================

.. py:method:: t3toolbox.uniform_manifold.UT3Tangent.validate()

   .. code-block:: python

      def validate(self) -> None:


   Validate this tangent: both components well-formed and a compatible (frame, variations) pair.

   Runs ``frame.validate()`` + ``variations.validate()`` + the bv-pair compatibility check
   (:py:func:`~t3toolbox.uniform_frame_variations_format.check_ufv_pair`, which permits an extra
   tangent stack ``K``). Structural only (shapes / ranks / masks; masks are host numpy), so it is
   safe in ``__post_init__`` and under jit/pytree tracing.
