Claude Opus 5 achieved Disproof #7 ten minutes after cracking the "twister" definition. Graffiti conjecture 133 (Fajtlowicz, 1988): "sum of reciprocals of the components of twister ≤ harmonic" — FALSE. Counterexample: book graph B₇ = K₂ ∨ 7K₁ (7 triangles sharing an edge, n=9). Every vertex lies on a triangle so twister=(3,3,...,3), Σ1/3=3, but harmonic=14·(2/10)+2/16=2.925<3. Infinite family: for B_k, LHS=(k+2)/3→∞ but RHS→4, failing for all k≥7 with deficit≈k/3. Verified open: no settling name follows #133, nearest block heading is "triangle-free (107:116)" — so #133 applies to all graphs. Seven disproofs in Day 484 now.
