and the proposal gate, the 104-node conclusion register and 14 continuation
inputs, current README/NEXT_STEPS, evidence/MISSING, NS100/101 arguments,
and PR73/75/76 audits. This is a dependency/method-feasibility review, not a
historical proof replay. Both original-evidence recovery groups stay OPEN.
Wall check: Same open gap — ZERO-GEOMETRY, NS100/101, PR73/75/76. What changes: no arithmetic hypothesis or estimating input has been supplied. The original integer-square coefficients distinguish the object from NS101; the reindexing, positivity of the Gaussian quadratic form and primitive boundary repair do not estimate its signed transform. No sign computation, scan, new row, thaw, manuscript version or external outreach is recommended.
Do not open a lattice/residue-class calculation task from the current representations. I found no specific signed lattice inequality or summation method beyond the existing unestimated target. The strongest immediate action is a stop on that task family until an explicit infinite regrouping and its estimating inequality are supplied. A request to find such a regrouping is not itself an admitted next step.
The exact target remains, for every real r including its zeros,
p = r^2 + 1/4,
J(r) = p^2*(Y'^2-Y*Y'') + 2*(r^2-1/4)*Y^2
= 16*(X'^2-X*X'') >= 0.
This is first-Laguerre positivity only. No implication from this single inequality to RH, G2 or the complete cofinal Weil floor is established.
This ledger explains the stop; it is not proposed as a new estimating input. On u>=0 use the original summands
q_n(u) = (2*pi^2*n^4*exp(9*u/2)-3*pi*n^2*exp(5*u/2))
*exp(-pi*n^2*exp(2*u)), n>=1,
a_n(r) = 2*integral_0^infinity q_n(u)*cos(r*u) du.
The original coefficients are exactly one for every n. Each q_n is positive on this half-line; the factor two from the original +/-n points is already in q_n. The complete theta kernel is the even extension of the complete sum, not the claim that each summand has smooth even extension. Gaussian summability of the first three weighted moments justifies X=sum a_n and its first two r derivatives, uniformly on the real r axis, and the complete double sum
B_nm(r) = a_n'*a_m' - (a_n*a_m''+a_m*a_n'')/2,
J(r)/16 = sum_(n,m>=1) B_nm(r).
B_nm(r) = integral_(u,v>=0) q_n(u)*q_m(v) *
[(u+v)^2*cos(r*(u-v))+(u-v)^2*cos(r*(u+v))] du dv.
Both phases and every mixed n,m term are required. The coefficients in this double sum are all one; arbitrary positive reweightings are not the original problem. A theorem that the matrix B(r) is positive semidefinite for every r would be much stronger and is already incompatible with the known finite prefix test below. No such all-coefficient inference is being proposed.
In PR75’s full-plane coordinates, k=n+m and l=n-m impose k=l modulo 2.
Both parity cosets and the coupling
2*sinh(2t)*k*l must be retained. Real diagonalization transports the lattice;
it does not turn it into independent integer coordinates. The half-line
formula above is just an absolutely convergent way to retain the same full
problem after reflection. It does not justify deleting either cosine or
either parity class.
Per-slice positivity is a known wall in its stated scope. NS100’s complete original slice has a certified negative cosine transform at frequency 40, and continuity extends this to nearby slices. Any proof requiring all such slices nonnegative is excluded. The full integral remains open.
Unfolding before completing the lattice repeats NS101. For the unreflected full-line summands, the absolute transform integral is a positive constant times n^(-x-1/2), where x is the real Laplace parameter. Summation is absolutely justified only for x>1/2, not at x=0 needed here. At x=1/2 NS101 even records the exact failure: each summand’s transform is zero while the transform of the full sum is 1/4. PR76 repairs the complete primitive’s boundaries; it does not license this different interchange.
Finite square prefixes cannot be the nonnegative blocks. Set H_M=sum_(n<=M) a_n and delta_M=sum_(n<=M) q_n’(0)>0. PR73 gives
L1[H_M](r) = -8*delta_M^2/r^6 + O_M(r^-8), r->infinity.
Thus sum_(n,m<=M) B_nm is eventually negative for every fixed M. Its omitted terms, including mixed terms, cancel this leading negative asymptotic. Neither a small real-space tail nor diagonal-block positivity replaces that cancellation. Finite boundary repairs with a later nonzero odd jet have the corresponding PR73 obstruction. This is not a no-go for genuinely smooth infinite resummation or height-dependent approximants.
Primitive structure is a known failed inference, not a lattice estimate. The NS101 reciprocal mixture retains PR76’s positive smooth primitive, envelope, unit tail and transform identities, yet J is negative in PR74’s stated beta range. It changes the integer-square coefficients and original Jacobi IVP. That mismatch leaves an arithmetic method open; it does not count as a control pass for the present representation.
For example, writing X=H_M+T_M makes the required compensation explicit:
2*H_M'*T_M' - H_M*T_M'' - T_M*H_M'' + L1[T_M]
>= -L1[H_M], every real r.
This is exactly the missing target, not an independent tail estimate. The mixed terms cannot be replaced by L1[T_M] alone. No lower bound for this quantity follows from the representations reviewed here.
Rechecked only arXiv sources already closest to this proposed mechanism. Kharchev–Zabrodin I, sections 3–4, uses common moduli in its ordinary addition identities; the variables s+t and s-t in this problem change moduli, not elliptic arguments. Kharchev–Zabrodin II, Proposition 3.1, does allow n1tau and n2tau with positive integers n1,n2 and retains the full residue-class sum modulo n1+n2. Its imaginary-part hypothesis is positive definiteness. The original scalar moduli match this restricted form when exp(4t)=n1/n2. The proposition is an identity; it supplies neither a signed lower bound nor transverse t-derivative estimates for PR75’s operator. Density of rational ratios does not provide those estimates. No further theta-positivity theorem is imported or claimed absent globally.
There is no unconditional additional 1–2 hour task to run from these results. Only if someone supplies an actual infinite Poisson/parity regrouping and an independent signed estimating mechanism, budget at most 2 hours for a completeness/admission check:
Success of that check would admit one sharply stated estimating lemma for further work; success of the lemma plus its complete error transfer would prove J>=0 and only the first-Laguerre target. Failure would stop that supplied regrouping. Neither outcome closes the original lattice method in general. If no regrouping and independent bound are supplied, the completeness check has no input and should not be started.
Final classification: Same open gap. No viable signed lattice estimate is admitted. RH, G2 and the cofinal signed-arithmetic lower bound remain open.
