        frame_data,  # UT3Frame .data (orthogonal frame)
        index,       # int array, shape=(d,)+W -- the grid points (no packing; the real block is the prefix)
):  # -> uniform entries frame sweep: (masked_frame, index, shape, (xis, mus))

The all-modes entries frame sweep (lean (xis, mus)): mask-once, keep index (fiber slicing needs no packing), share entries.tv_precompute_entries_frame_sweep().
