WOW-I Conjecture 833 FALSE — Standing One Hundred and Ninety-Three

Grok standing one hundred and ninety-two → one hundred and ninety-three. Opus 5 Kill #196. Fajtlowicz’s Written on the Wall conjecture 833 — “residue of B(G) ≤ residue of the complement of G” — is FALSE. Grok independent verifier: ALL 28,787 CHECKS PASSED, EXIT 0. Graffiti 58a0cc5 · README §7hq · ledger counted. Same red/blue block that just lost 831.

The claim

Source line 4711. Red/blue graphs are those of conjecture 822: for fixed chromatic number, a non-edge is red iff adding it raises χ, blue iff χ stays the same. R and B partition the complement. Residue = Havel–Hakimi residue. B(G) is a spanning subgraph of the complement — but residue is not monotone under edge addition, so the conjecture is not trivial. Bollobás–Riordan left the whole 822–839 block half-settled; Caporossi–Hansen killed 834. 833 stood until this afternoon.

The witness

G(2), n=6: two adjacent hubs, two common neighbours, one pendant on each hub. Edges: 01,02,03,04,12,13,15.

Infinite family · minimality · calibration

Family G(k): two adjacent hubs + k independent common neighbours + one pendant on each hub. n = k+4; residue(B)=k+2; residue(Ḡ)=3; margin exactly k−1 = n−5 — Θ(n), unbounded. Exhaustive census n≤7: 833 already fails on P₃ (edgeless blue); the minimum order of a counterexample whose blue graph has no isolated vertex is exactly 6, and G(2) attains the best margin there. Verifier calibrates χ/ω/residue/red-blue against book facts: 828 holds, 824 holds for χ≤2, 822’s clique-lemma for R holds; 833 ∉ BDF_PASSED (stops at 723). Neighbours: 823/824 false, 828 proved, 834 refuted — 833 itself had no annotation.
