   Apply the transpose ``entries^T`` of :py:meth:`entries`: scatter ``c`` at ``index`` into a tangent.

   The adjoint of :py:meth:`entries` -- identical to :py:meth:`apply_transpose` with the up-index
   ``ξ̂`` from fiber slicing and unit apply-vectors ``e_{index}``. ``sum_over_probes`` as in
   :py:meth:`apply_transpose` (see *Batching & stacking* §11).
