In Z[omega], $\omega =\exp (2\pi $ i/3), let primary primes pi satisfy $\pi =1$ modulo3, let $chi_\pi $ be the cubic residue character, and put $G(\pi )=N(\pi )^{-1/2}$ $sum_(v$ modulo pi) $chi_\pi (v)$ exp(2pi i Tr(v/pi)).

Patterson first moment over Eisenstein primes
OpenAI's claim
OpenAI presents the following claims relevant to this question, with manuscript numbers following paper order in Sources. In manuscript 1 (family 023; 2026-09-25), the asserted result is that averaging cubic Gauss sums with the prescribed normalization over the entire primary Eisenstein-prime set gives Patterson's main term, and every fixed nonzero angular mode contributes a negligible amount.Mathematical statement of the claimed result
Manuscript 1.
Set $\omega=e^{2\pi i/3}$, $\mathcal O=\mathbb Z[\omega]$, $N(b)=b\bar b$ and $\operatorname{Tr}(z)=z+\bar z$. For a primary element $b\equiv1\pmod3$, let $\chi_b$ be its cubic residue symbol, zero on nonunits, and define \[ G(b)=N(b)^{-1/2}\sum_{v\bmod b}\chi_b(v)e^{2\pi i\operatorname{Tr}(v/b)},\qquad c_*=(2\pi)^{2/3}/(3\Gamma(2/3)). \] The claimed unconditional sharp-cutoff first moment is \[ \sum_{\substack{N\pi\le X\\\pi\equiv1\pmod3\text{ prime}}}G(\pi) =\tfrac65c_*X^{5/6}/\log X+o(X^{5/6}/\log X)\quad(X\to\infty). \] All primary prime elements are included, in particular both conjugate primes above a split rational prime.Outline of the argument
For manuscript 1 (family 023; 2026-09-25), angular Hecke characters and a Voronoi transformation give Type I estimates. Corrected dispersion and exceptional-moment bounds are joined to an exact prime decomposition, and smoothing is removed only after each fixed angular mode has been controlled.Formal verification
For manuscript 1 (family 023; 2026-09-25), OpenAI lists Lean statements for this assertion: averaging cubic Gauss sums with the prescribed normalization over the entire primary Eisenstein-prime set gives Patterson's main term, and every fixed nonzero angular mode contributes a negligible amount.The central assertion is within the documented formal scope; the additional applications retain their own scope limits.
