def ufv_share_tucker_variations(
        variations_data,   # UT3Variations .data: (tkv_sc, ttv_sc, shape, (4 masks)); stack = K + C
        shared_data:    'SharedFrameData',  # the frame's UNIFORM companion (ufv_shared_frame_data)
        rcond:          float = None,         # relative clip on the group spectrum; None -> dtype eps * max dim
):  # -> tied variations .data (same masks; padded rows come back exactly zero)

The uniform twin of fv_share_tucker_variations() (the manifold tied post-pass): mask the variation supercores, delegate to the polymorphic ragged solve on the mode slices, re-stack. The companion’s masked U_M zeroes every padded row of the redistribution, so the output is masked-clean and the masks are unchanged.
