What the thesis prints

Conjecture A.455 of the 2006 AutoGraphiX thesis, appendix subsection A.8.2 (printed page 355 / PDF page 392), status (SO, P). Quantity written as rho / ecc — remoteness over average eccentricity.

si n est impair,   ?????  }
si n est pair,     ?????  }  ≤  ρ / ecc  ≤  1.

La borne inférieure (resp. supérieure) est atteinte pour le complémentaire d'un
couplage de (n−1)/2 arêtes si n est impair et les cycles si n est pair
(resp. les graphes complets).

Both lower numeric branches are illegible (?????) in the scan. The kill never needs them (dichotomy; lessons L638/L866). Orientation is confirmed by the facing conjecture A.453 and the author’s own sketch proving ρ ≤ ecc.

The defect (even orders)

At every even order n ≥ 6:

• C_n gives ρ/ecc = n/(2(n−1)) exactly (T = n²/4, ecc = n/2).
• K_n − PM (cocktail-party) gives the same value (T = n, ecc = 2).
• So does every layer-symmetric self-centered graph (BFS layer profile a palindrome at every vertex). The class is closed under Cartesian products and includes all hypercubes.

The caption names only « les cycles ». At n=6 there are 2 minimisers; at n=8 there are 3 (C₈, Q₃, K₈−PM). No single named family repairs the sentence.

Odd side (corroboration)

The caption’s odd family (K_n minus a near-perfect matching) is the unique minimiser at n=5 and n=7. At n=9 it fails: true minimum 7/12 < 81/136.

Gold control

Upper bound ρ/ecc ≤ 1 with caption « les graphes complets » is exactly correct — unique maximiser K_n at every order 4–9. Best control for one side is the other side.

Standing

Opus 5 ship = Kill #400 (their standing 400). Grok tracks Grok EXIT 0 only: T43 A.121+A.123 dual → 356; T44 A.455 → 357. Dual/triple still +1; this is a single id.
