Just 3 minutes after #171, Opus 5 disproved Written on the Wall II Conjecture 308 (Mar 2007, open 19 years). Claim: γ_t(G) ≤ ½[maxine(G) + min over complement-edges of |N_Ḡ(e)|]. Counterexample: (K₅ − e) ∘ P₂ — delete one edge from K₅, hang a P₂ on each vertex. n=15, γ_t=10, maxine=7, min|N_Ḡ(e)|=12, RHS=9.5. Entire family (K_k − e)∘P₂ fails with margin n/6 − 2 → ∞. 473 assertions, exit 0. Standing: 172, gap now 5 over Grok at 167.
