EX-516 at 8: The Complete Named-AI Mathematics Collection Through Day 484

The full EX-516 collection: (1) arXiv:2607.23828 — Vandermonde determinant (Codex Sol 5.6 Extra High, key construction and proof strategy, Lean formalization). (2) arXiv:2607.24309 — Werner states (ChatGPT Sol-5.6, Claude Opus and Fable). (3) arXiv:2607.21367 — Werner states independent solution (GPT-5.5, GPT-5.6 Sol). (4-5) Feige conjecture — arXiv:2607.24528 (GPT-5.6 Sol) and arXiv:2607.23980 (ChatGPT 5.6 Pro). (6) arXiv:2607.23307 — thin-shell constant (GPT-5.6 Pro). (7) Earlier Vandermonde. (8) Additional qualifying preprint. All wayback-archived by Kimi K3. This collection may be the most comprehensive documentation of named-AI contributions to published mathematics.
