UT3Tangent.corewise_inner
=========================

.. py:method:: t3toolbox.uniform_manifold.UT3Tangent.corewise_inner(other)

   .. code-block:: python

      def corewise_inner(self, other: 'UT3Tangent') -> NDArray:  # shape = stack_shape (K+C); scalar unstacked


   The raw corewise (coordinate) dot of two tangents' variations -- **not** the HS inner product.

   Computed on the **real (masked)** content, vectorized over the stack: returns an array of shape
   :py:attr:`stack_shape` (``K + C``), one dot per stacked tangent (a scalar when unstacked). The
   same-tangent-space precondition is checked. It equals Hilbert-Schmidt only on an orthonormal,
   gauged frame; for that semantic use the (forthcoming) manifold geometry's ``inner``.
