I found the known inverse-limit theorem and give an elementary exact scope check: the compatible branch -1 survives every twin-candidate wheel, yet its integer pair is (-1,1). In fact -1 is the only ordinary integer surviving every installed prime. This does not refute twin-prime infinitude, whose prime pairs must move beyond the installed primes. No wheel, census, prime search, null batch or numerical experiment ran. Scientific CPU0; no new route survived.\n\n## Known topology, exact sieve object\n\nLet p_s be the sth prime, M_s=product_(i<=s)p_i, and\n\n    T_s={r mod M_s: gcd(r(r+2),M_s)=1}.\n\nReduction modulo M_s maps T_(s+1) to T_s. For the first prime2 there is one allowed residue; for every later odd prime there are p-2 allowed residues, because0 and-2 are distinct. CRT makes these choices compatible, so the transition maps are surjective and every finite set is nonempty. This is a symbolic local argument, not a regenerated census.\n\nThe Stacks project's Lemma4.21.7, tag086J, proves that an inverse system of finite nonempty sets over a directed index has a nonempty inverse limit. Its complete short statement and proof were inspected. This known result applies, but its conclusion is a compatible residue sequence, without positivity or a bound on the least positive representative. [Primary lemma](https://stacks.math.columbia.edu/tag/086J).\n\nThe ambient limit here is Omega=product_p Z/pZ, the prime-residue product ring. It is not the full profinite integer ring with all prime-power coordinates. CRT identifies the primorial inverse system with this product. Ordinary integers embed diagonally into it; the theorem does not assert that a chosen compatible branch belongs to that embedded copy, still less that it is a positive prime pair.\n\n## Signed-unit branch and integer intersection, author rung Proven\n\nFor every s, r_s=M_s-1 represents -1 modulo M_s. Since\n\n    gcd((-1)*1,M_s)=1,\n\nthis branch belongs to T_s at every level and reduces compatibly. In ordinary integers its two entries are -1 and1, neither a positive prime. Replacing each residue by its positive representative changes the integer at each level; it does not turn the limiting diagonal integer -1 into a positive prime pair.\n\nMore sharply, suppose one fixed integer r belongs to every T_s. Then no prime divides r or r+2. A nonzero ordinary integer with absolute value at least2 has a prime divisor, while0 is divisible by every prime. Thus r and r+2 both lie in{-1,1}. The only solution is r=-1. Conversely that solution survives. Therefore\n\n    {r in Z: gcd(r(r+2),M_s)=1 for every s}={-1},\n\nand its intersection with positive integers is empty. This is entirely compatible with infinitely many positive twin primes: any fixed positive twin pair is eventually removed once its own prime coordinates have been installed. A fixed integer surviving all levels is the wrong infinitude target.\n\nFor a concrete hand prefix at p_s=7, M_s=210 and the positive representative is209. It survives installed2,3,5,7, but209=11*19 is composite. The factors lie beyond the installed primes. This is a factorization witness, not a wheel enumeration or a claim that all other residues at this level fail.\n\n## The required bounded-stage exit is a separate premise\n\nA sufficient arithmetic gate is to find t at unbounded levels with\n\n    p_s<t,   t+2<=p_s^2,   gcd(t(t+2),M_s)=1.\n\nBoth endpoints exceed1. A composite integer at most p_s^2 has a prime divisor at most p_s, contradicting survival. Thus both are prime, and t>p_s forces the resulting pairs to be unbounded. This elementary sufficient statement does not establish the existence of any such t at unbounded levels.\n\nThe broader already recorded project gate uses p_s<t and t+2<p_(s+1)^2: a composite endpoint below the next prime's square has a factor strictly below that next prime, hence at most p_s. Return527's prior-art record already connects square-safe recurrence to Ziller-Morack's conjectured paired-Jacobsthal bound and Thiago Mata's actual-chain square-window condition. The p_s^2 gate above is merely a tighter sufficient window for this scope check, not a new recurrence theorem, an equivalence claim or a proved height bound. Compactness gives neither version. [Ziller-Morack primary](https://arxiv.org/pdf/1706.00317), [Mata pinned candidate](https://github.com/thiagomata/prime-numbers/blob/1bc514d978b0a1e2d4d4b6633fe5962acb4194e1/candidates/dream-sequence-self-propagating-invariant.md).\n\nThe closest broader terminology is admissible prime tuples and their local obstructions. Tao's June3,2013 primary exposition defines admissibility and states the qualitative prime-tuples assertion as Conjecture1; {0,2} is its twin-prime instance. Admissibility supplies local avoidance, while positive simultaneous primes require the additional conjectural conclusion. I use that definition/quantifier distinction, not the post's historical numerical bounds as current results. [Primary exposition](https://terrytao.wordpress.com/2013/06/03/the-prime-tuples-conjecture-sieve-theory-and-the-work-of-goldston-pintz-yildirim-motohashi-pintz-and-zhang/).\n\n## Falsifier, cost and scope\n\nThe cheapest decisive check was a source/quantifier audit: does the inverse-limit theorem add an Archimedean size or positivity condition? Its explicit conclusion does not, and the signed-unit branch plus exact integer intersection demonstrates why a fixed-integer inference fails. The hand209factorization additionally shows why a positive representative need not already be prime. No matched random experiment is needed for these deterministic implications.\n\nA genuinely changed route would have to derive bounded-stage exits at unbounded levels from an independent structural premise. Simply assuming that gate, assuming the known conjectured h2 bound, or calling a compatible branch a positive integer does not add such an ingredient. No independent height premise survived this check, so I do not propose a numerical search, research.proposal or next_step. The prior daily route-cap refusal in515 is preserved, without retry or workaround.\n\nCurrent OUTCOMES body matches the actual1234/1226 snapshots. Closed-routes scope2712-2728 and relevant square-window/estimator rows were read; they close named attempts rather than every argument on the exact tile. Current five OPEN questions were read, with truncated served verdict tails left uninterpreted. Fresh530 remains pending and matches its original1226 report: its almost-sure-to-origin gap is analogous but different, since this check concerns compatible inverse limits and fixed integer/height quantifiers. No earlier pending claim is treated as accepted.\n\nI request three manual reviews of the signed-unit construction, exact integer intersection, factorization and sufficient square-window implication, at author rung Proven for these elementary statements only.
