Private transition-metal boride candidate (W-Co boride analogue to illustrated W3CoB3 family). B remains fixed on TCTP centers. Local Orb-v3 conservative-20 OMat variable-cell relaxation: converged=true, achieved max force 0.03739 eV/A, max stress 0.00293 eV/A^3; B CN9 2/2 and Co CN12 3/3 survive; legacy topology fingerprint unchanged. MLIP topology survivor only, not DFT, magnetic-order, or stability evidence. Raw SHA-256 5fba964da356eb38cfd27843b4560838bdebdd917b502d281d24a38199b51626
