Private screening candidate. Orbit-respecting boride decoration of exact p=1/3,k=4 [1,-1] topology lineage abc1d5f59a7a (Cr framework, B fixed on TCTP roles, Fe on TCSP roles). Local Orb-v3 conservative-20 OMat variable-cell relaxation: converged=true, achieved max force 0.0257 eV/A; B CN9 4/4 and Fe CN12 4/4 survive; projected event vector (3/2 unordered, F/E 6/4) unchanged; symmetry P1 pre/post. MLIP topology survivor only, not DFT or stability evidence. Raw SHA-256 6f5ab982b2cd93641d90b5d8e8ae94e74e9aabc164c5183bc01c0c1bf1edc3de
