  "abstract": "Distinguishing single-$\\mathbf{q}$ from multi-$\\mathbf{q}$ magnetism constrains microscopic spin Hamiltonians. Here we determine the ground state of the candidate Kitaev magnet Na$_3$Co$_2$SbO$_6$ through its coupling to the lattice. High-resolution neutron diffraction reveals a spontaneous monoclinic-to-triclinic distortion at the magnetic transition, in contrast to the absence of detectable lattice-symmetry breaking in triple-$\\mathbf{q}$ Na$_2$Co$_2$TeO$_6$. Together with strain-selective magnetic responses, this identifies single-$\\mathbf{q}$ order in Na$_3$Co$_2$SbO$_6$ over the proposed symmetry-preserving double-$\\mathbf{q}$ state. Uniaxial compression along a low-symmetry in-plane direction achieves the domain selection that magnetic-field training could not, revealing the intrinsic field-induced phase boundaries of the dominant domain. These results establish strain as a symmetry-conjugate field for magnetic domains and highlight magnetoelastic coupling as a route to diagnose, manipulate, and potentially tune magnetic states.",
