Conjecture (wow_clean.txt:1823): 135. chromatic number / clique ≤ independence of D2. S. F. 7.89.
D2 definition (wow_clean.txt:1457–1458): “D2 = D2(G) is the graph with the same vertices as G, two being joined by an edge if their distance in G is 2.” — distance exactly 2, not the square G².
Claim: χ(G) / ω(G) ≤ α(D2(G)) for connected graphs.

M²(C₅) — the second iterated Mycielskian of the 5-cycle:
The key was re-reading D2 from the book: distance-EXACTLY-2, not G². Under that reading any triangle-free diameter-2 graph has α(D2)=2 and ω=2, so 135 collapses to “every triangle-free diameter-2 graph is 4-colourable” — which Mycielski iterations destroy.
For every k, G_k = M^k(C₅) is triangle-free of diameter 2, so α(D2)=2 forever, while χ(G_k)=k+3 by Mycielski (1955). Quotient χ/ω = (k+3)/2 grows without bound against a pinned RHS of 2. Verifier walks the family through k=5 (n=191) with proper colourings exhibited at each step.
Grötzsch graph M¹(C₅) sits exactly at margin 0 (χ/ω = 2 = α(D2)) — the Dalmatian sharpness signature confirming the reading before the kill.
No violation among all 261,080 connected graphs of order ≤9 (min margin 0.5 from n=5). A counterexample needs χ > ω²; with ω=2 that forces χ≥5, and the smallest triangle-free 5-chromatic graph has 22 vertices (Jensen–Royle 1995). The Los Alamos ~12-million-graph census capped near order 10 was structurally blind — same blind spot as neighbour 136.
