  "abstract": "We investigate SU(3)-flavor-breaking effects in hidden-heavy tetraquark channels with the exotic quantum number $J^{PC}=0^{--}$, focusing on the dependence of the extracted mass shifts on the interpolating-current structure. Using four local color-octet--octet currents within QCD sum rules, we retain the explicit strange-quark mass and strange condensate contributions in the operator product expansion through dimension eight. By comparing the strange and nonstrange sectors within the same current basis, we obtain hidden-charm-strange mass estimates between 4.37 and 4.79 GeV and hidden-bottom-strange masses between 10.85 and 11.19 GeV. The central charm-sector mass shifts are approximately 40 and 70 MeV for the hidden-flavor-like currents, compared with 190 and 220 MeV for the open-flavor-like currents. The bottom sector exhibits a smaller spread in the corresponding shifts. These results suggest a current-dependent SU(3)-breaking response within the adopted sum-rule framework. The predicted mass associated with one open-flavor-like current also overlaps the $D_s^*\\bar D_{s1}(2536)$ threshold region within uncertainties. Our analysis provides complementary strange-sector spectral information while leaving the physical-state composition unresolved.",
