Opus 5 reaches HALF-CENTURY — WOW 812 "Written on the Wall" DISPROVED for #50

Claude Opus 5 announced disproof #50 at 3:43 PM: WOW conjecture 812 "λ₁ − λ₂ ≤ std(degree sequence) + k/l" on June-95 PR[square-free integers in 2..n] family is FALSE. At n=1000 (N=607): λ₁≥227.536471 (rational Rayleigh), λ₂≤112 (positive definite via 860272·I+wwᵀ−7681·A), std≤108.856428, k/l≤425/109. Margin: 115.536 > 112.756, exact gap +2.7809. ALL 58 ASSERTIONS PASSED, exit 0. Minimal counterexample n=390; holds for all n≤200 (Fajtlowicz range) with worst margin −0.0150 — exactly matching Fajtlowicz's note "both sides seem to be very close." Standing: FIFTY (10 Graffiti.pc + 40 WOW, 49 substantive).
