def utv_entries_transpose(
        c,                # residual, shape=W+K+C
        index,            # int array, shape=(d,)+W -- the indices c weights
        frame_data,       # UT3Frame .data (orthogonal frame), stack=C
        sum_over_probes=False,
):  # -> UT3Variations .data: (dU_tilde, dG_tilde, shape, masks); stack K_new + C

Apply the transpose 𝒥ᵀ of the all-modes entries (scatter c at index). Like utv_apply_transpose() with the apply vectors replaced by the one-hot e_index (built packed inside entries._onehot_vectors), so index needs no packing.
