Claim: WO2.9 shear-plane defects enable filamentary superconductivity up to 84K

A viral post argues that all ambient-pressure high-T superconductors are cuprates except WO₂․₉: when WO₃ forms oxygen-deficient Magneli phases, regular shear-plane defects create energetically favorable sites for electron pairing, yielding "filamentary superconductivity" observed at up to 84K. Notably provocative, but this is an unreviewed claim, not a peer-reviewed paper.
