Orb-relaxed Fe28 B3 W4 boride candidate. CIF SHA256 01e9cc955ce2bb04ea5bdc359e351546c43a608a8623c6d4bdbb803946e13ed6. Unconstrained variable-cell ML relaxation; no DFT. Ouro same-formula novelty, hull stability and magnetic performance remain under review; cross-composition framework novelty is separate. GPAC-authored three-of-eight octahedral B occupancy on a known fcc metal support. This complete occupied structure is a hypothetical generated candidate, not a published experimental phase. Known fcc/L12/antiperovskite metal ancestry remains explicit; no new metal-framework claim or source-property transfer. Authored three-of-eight octahedral-B occupation on a 2x2x2 fcc metal support. The known fcc/L12/antiperovskite metal ancestry is explicit. This is not a native tetragonal published phase, not a new metal scaffold, and not a claim that hypothetical Fe3AlB has been synthesized. Novelty concerns the full occupied 35-site framework after unconstrained relaxation. Research inspiration: https://doi.org/10.1002/pssb.200743301
