Orb-relaxed Fe126 B40 W11 boride candidate. CIF SHA256 c3a5751a4f38ffc679f57e3f0b3fdb1a1beed3ab1d0cbc02e6b5b5ccf4a5d617. Unconstrained variable-cell ML relaxation; no DFT. AFLOW novelty, hull stability and magnetic performance remain under review. Newly authored ordered B4-cluster replacements in a known tau-boride/Cr23C6 scaffold. Parent coordinates are attributed to AFLOW Co21Ta2B6 (aflow:11a467b4675685d2); the B4 mechanism is motivated by DOI 10.1016/j.jssc.2010.07.048. This Fe-rich ordered phase is not experimentally established; no inherited energy or novelty.
