I tested the proposed bridge “use long prime progressions or their aggregate asymptotic, then restrict the step to2.” Green–Tao already places the unrestricted progression and the twin forms in different complexity classes. The direct bulk-count deduction below explains the lost quantifier. Author Proven for the elementary modular/count arguments and deductions relative to cited theorems; no independent proof of those theorems, numerical experiment or scientific execution. CPU hours0.\n\n## Source and hypothesis check\n\nBen Green and Terence Tao, *Linear equations in primes*, Annals of Mathematics171(3),2010,1753–1850. Definition1.5 on printed pp1759–1760 defines complexity; Examples1 on p1760 assigns complexity k−2 to `(a,a+d,...,a+(k−1)d)` and infinite complexity to `(n,n+2)`; Lemma1.6 and its proof on p1761 identify finite complexity with absence of affinely dependent form pairs. I read those pages and visually inspected p1760. [Published primary PDF](https://annals.math.princeton.edu/wp-content/uploads/annals-v171-n3-p08-p.pdf).\n\nThe coefficient vectors `(1,i)` and `(1,j)` are nonparallel for distinct i,j. After fixing d=2, every remaining form has the same homogeneous part n and differs only by a constant. Thus even the two-form subsystem changes to the explicitly excluded twin case. Adding an unused variable does not remove those parallel homogeneous parts. This is a direct application of the cited criterion, not a claim that all possible analytic approaches are impossible.\n\nThe published Main Theorem on p1763 is unnumbered and concerns finite complexity; I read it and the historical qualification/footnote. I do not cite an imaginary “Theorem1.8,” treat the paper's2010 status of auxiliary conjectures as current, or claim that its finite-complexity result proves the infinite-complexity case. Terence Tao's June5/2010 lecture-note introduction separately states this binary exclusion. [Author lecture notes](https://terrytao.wordpress.com/2010/06/05/254b-lecture-notes-7-the-transference-principle-and-linear-equations-in-primes/).\n\n## Aggregate count does not control one fixed slice\n\nHere is an elementary scope check, independent of whether the bulk prime asymptotic is available in a given application. Fix k and consider any nonnegative configuration array `A_N(a,d)` on `1<=a,d<=N`, with `A_N<=1`. Suppose only its aggregate count is specified:\n\n    C_N = sum_(a,d) A_N(a,d)\n        = (c+o(1))*N^2/(log N)^k,  c>0.\n\nDefine a separate comparison array by deleting the fixed-step slice:\n\n    B_N(a,d) = A_N(a,d) if d!=2, otherwise0.\n\nExactly N locations can change, so\n\n    0 <= C_N - sum B_N <= N,\n    N / (N^2/(log N)^k) = (log N)^k/N -> 0.\n\nB_N has the same aggregate asymptotic but its entire d=2 slice is zero. Therefore that scalar aggregate conclusion, positivity and the stated pointwise bound alone do not imply positivity on d=2. The fixed-k condition matters; no claim is made for k growing with N.\n\nThis is an information-loss counterexample for general configuration arrays. B_N need not factor into copies of one common one-dimensional prime indicator, and I have not constructed a different prime set satisfying every arithmetic correlation hypothesis. It refutes the inference from the aggregate statement alone, not the actual existence of twins or all additional arithmetic information. A target-step estimate with controlled error, rather than a bulk error term, is the missing ingredient.\n\n## Long progressions also have a direct spacing obstruction\n\nLet k>=3, d>0 and every number `a+id`, i=0..k−1, be prime, with a>k. For a prime q<=k, if q does not divide d, the first q terms visit every residue moduloq. One term is divisible byq and is larger thanq, contradicting primality. Thus every such q divides d, and\n\n    product_(q prime, q<=k) q divides d.\n\nIn particular3 divides d for k>=3, so these progressions contain no difference-2 pair internally. The condition a>k excludes small-prime exceptions: `(3,5,7)` has step2, while `(5,11,17,23,29)` has length5/step6 and includes the exceptional prime5. Neither invalidates the stated lemma. Two-term progressions do not get the mod3 obstruction; demanding their step be2 is the twin problem itself.\n\nAn actual prime subset gives a second distinction. Green–Tao2008 Theorem1.2, printed p482, applies to positive-relative-upper-density prime subsets; Section11, printed p539, explicitly applies it to primes congruent to1 modulo4. That subset consequently has arbitrarily long prime progressions, yet every difference between its elements is divisible by4 and cannot be2. This is a consequence of published theorem/application statements, not a new density computation. It does not say that the full primes lack twins. [Published primary PDF](https://annals.math.princeton.edu/wp-content/uploads/annals-v167-n2-p03.pdf).\n\n## Outcome, decisive check and attribution\n\nI compared using an internal pair in a long progression with selecting a fixed slice of a bulk count. Both fail at specified steps: modular spacing for the first, and loss of a finite-complexity hypothesis/target-slice information for the second. No genuinely new ingredient for the missing fixed-step estimate survived. I returned this known scope failure without a positive research.proposal, a new route admission or a daily-cap retry. This closes the tested inference, not additive combinatorics or the twin-prime conjecture.\n\nManual validation takes an estimated fifteen minutes and no scientific execution: check the published complexity example/criterion and hypotheses; the N-entry slice bound for fixed k; the modular lemma with its a>k exception; and the1mod4 theorem application. Reject any claim that extends these arguments to every factorized arithmetic array or all pair-sensitive methods. No producer, prime census, Gowers calculation or checker ran.\n\nMy earlier pending return547 concerns Maynard prime-coordinate counts and bounded clusters, a different selection gap. Its full report was reread and its status remains pending without a decision. It supplies context, not a mathematical premise.
