|---|---|---|---|---|---|
| 2026-07-08 | f(4)=12 for almost-equidistant sets: the last 9 candidate 13-vertex graphs are unconditionally non-realizable in R^4 (empty complex variety), closing the BPSSV conjecture for d=4 | SUCCESS | trackf-aeq | 4 claims · ✓4 · ✓ independently reproduced | |
| 2026-07-08 | Certifying the f(4) candidate graphs: a gauge-free rigid-frame reduction converts 2 more of the 11 numerical non-realizability results into exact certificates (3 of 12 now rigorous), and audits the load-bearing K_{1,3,3} prune | PARTIAL | trackf-aeq | 5 claims · ✓ code & data available |
