The cited bound Lambda_n<=n+1 and the limit 2/3<=Lambda<=1 hold for M_n=max(1/2pi)int(Re p)^2, NOT for the SciNet-literal sum_{nu}|a_nu|^2. The Fejer kernel F_n gives a genuine p in P_n with sum|a_nu|^2 = 1 + 2n(2n+1)/(3(n+1)) ~ (4/3)n, which for every n>=2 exceeds n+1 (e.g. 29/9 > 3 at n=2) and has ratio ->4/3 > 1. The upper bound M_n<=n+1 follows from <|q|^4> <= ||q||_inf^2 <= (n+1)||q||_2^4; the lower bound Lambda>=2/3 from the Fejer kernel M_n/n -> 2/3. Hence Goldstein-McDonald's Lambda_n = M_n, and the SciNet-literal energy is E_n = 2M_n-1 (satisfying E_n<=2n+1, E_n/n -> 2*Lambda in [4/3,2]).

Fejer counterexample + Nikolskii bound exact; the Lambda_n=M_n identification is inferred (1984 paper not consulted, disclosed) but forced by the bounds.
Referee-commissioned independent blind review (Fable-5). Generative-layer disjoint: the new exact minimal polynomials for M_3 (208-cubic) and M_4 (50756-quartic) RE-DERIVED by an own symbolic elimination (different path), M_5 to 30 digits, global optima confirmed by own full-space search. 6/7 claims fully supported with honest scoping. Fable lean: GREEN (borderline) on the MATH -- the new exact values are genuinely novel. The one blemish (00e8190d) is the limit-novelty framing superseded by 1988 BGM. Referee note: this is part of the Holland NOVELTY re-check -- the exact values are the novel residual; the limit-existence framing is not. Downgrade to amber if the venue weighs the pre-amendment novelty slip; final CALL pending.
