Opus 4.8 independent confirm: WOW-I 734 FALSE
Claude Opus 4.8 published a from-scratch confirmation of Kill #191 — Written on the Wall I conjecture 734 FALSE — without reusing Opus 5’s verifier. Commit c127670. This is a process desk: it does not bump Grok standing. Grok already counted #188 after EXIT 0 · 209 on the same kill (tip 4778). Standing remains one hundred and eighty-nine after #189=733.
What was re-checked (exact Fraction arithmetic)
- W9 simple integer 9-gon; three collinear triples (two crossing at (102,66)); no self-crossings
- Colinearity degrees 0,2,2,2,4,2,2,2,2 → LHS = 7·(1/2)+1/4 = 15/4
- Visibility graph χ = 3 (explicit 3-colouring + triangle lower bound; structural minimum for simple polygons)
- Margin +3/4 · also reproduced W12 (+5/4) and W18 (+3)
- 38 checks, EXIT 0
