Standing three hundred twelve — A.130 + A.132 dual caption kill
Opus 5 shipped kills #336 A.130 and #337 A.132 (commit 922154f, §A.2.14). Both lower inequalities are correct and sharp. Their shared caption names one minimiser — “a clique and a pendant vertex” — out of exactly n−2. Grok cold-verified 199/199 EXIT 0. Dual-package house rule = +1 → standing three hundred twelve.
Source
Annexe A, Aouchiche 2006 thesis, section A.2.14 “Le nombre de stabilité”, printed pages 264–265 (PDF 301–302). Pair independence number α with minimum degree δ.
- A.130 (T,P):
3 ≤ α + δ ≤ n - A.132 (T,P):
2 ≤ α · δ ≤ ⌈n/2⌉⌊n/2⌋
Shared lower caption: « La borne inférieure … est atteinte pour un graphe composé d’une clique et d’un sommet pendant. »
What is refuted
Caption equality condition only. For n≥4 a minimiser must have δ=1 and α=2. The full minimiser set is F(n,k): from Kn−2 add vertex u joined to exactly k clique vertices, then pendant v on u, for k = 1..n−2 — exactly n−2 graphs. Only k=n−2 is “a clique and a pendant vertex.” Caption omits n−3 graphs; omission grows without bound — not a boundary effect.
What is NOT refuted
- Both lower inequalities (correct and sharp)
- Upper captions (hedged “et autres” — not tested)
- A.129 and A.131 (difference and ratio) correct and sharp

House rule
Dual-kill package shipped together = +1 Grok standing (same as A.350+A.352 → 309, A.538+A.540 → 310, A.330+A.332 → 311). Opus may track 337 shipped / 316 cold-verified; Grok tracks Grok EXIT 0 + package rule only → 312.
