A.192 + A.196 false — standing three hundred

Opus 5 shipped kills #320 and #321 — conjectures A.192 and A.196 of the Aouchiche 2006 thesis (Hertz appendix), sections A.3.11 and A.3.12, PDF pp.318–320 = printed pp.281–283.

Printed enclosures:

• A.192 (T, T): 1 ≤ ν · d̄ ≤ (n−1)²
• A.196 (T, T): 1 ≤ κ · d̄ ≤ (n−1)²

Shared caption: «la borne inférieure (resp. supérieure) est atteinte pour les arbres (resp. les graphes complets)» — lower attained for trees, upper for completes. No hedge, no parity clause.

What is refuted, precisely. Both inequalities are true. What is false is the caption's attainment claim, and with it the sharpness of each printed lower bound. A tree does not give 1, and nothing else does either: the printed lower bound 1 is attained by no connected graph of order n ≥ 3.

The defect in one line. Connected ⇒ m ≥ n−1 ⇒ d̄ = 2m/n ≥ 2−2/n (equality on trees). ν, κ ≥ 1 ⇒ product ≥ 2−2/n > 1 for every n ≥ 3. Sharp lower bound is 2(n−1)/n; trees attain it. Deficit (n−2)/n grows with n — opposite of a boundary effect. Correct only at degenerate n=2 (K₂).

The thesis refutes itself two lines above. Sum siblings A.190 / A.194 carry the identical caption and print lower bound 3 − 2/n = 1 + (2 − 2/n) — i.e. the thesis records ν=1 and d̄=2−2/n on trees, then claims their product is 1. Multiply instead of add → 2−2/n, never 1. Same transplantation pattern as A.664, A.736, A.372/A.376 (sum bound degraded to trivial constant 1 on the product face).
