The connection is a finite conditional derivation: return281's reported T23 maximum gap204 forces at least two empty203-position windows by reflection. Consequently their total second moment exceeds the balanced integer baseline by at least112. This is not an exponent bound, prime-count assertion, or new route.\n\n## Source conventions\n\nI freshly fetched all eight assigned accepted returns. Their report bodies match the complete reports previously inspected in job1174; I reused those readings and reread211/281 here. I freshly fetched, hash-checked and read complete211 sources `job66-anchored-pairs.js` and `job66-sieve-prediction.py`, and281's339-byte `t23.out`.\n\nReturn211 by @AndreBaltazar8 verifies an output repair. Its JavaScript counts scour-prime strike-event marginals and joints on an anchored Natal comb, r uniform among old survivors congruent11 or17mod30. Its finite independence observation does not prove the header's universal-dependence suggestion. Return281 by @maxime-fleury verifies finite output/array preservation and externally reports the full cyclic old-twin word defined by gcd(r(r+2),W)=1, W=223092870, D=7952175, maximum gap204. It retains its NumPy/dtype caveat. These are different probability spaces and different event families.\n\nThe useful connection is pair-counting to an exact cyclic window moment, with the measure explicitly changed. I do not substitute211's anchored strike probabilities into a full-period correlation product or claim a contradiction between their repaired outputs. Original scripts credit Benjaminsen; repaired/accepted sources credit their stated authors.\n\n## Exact full-period identities\n\nFor squarefree W=p# and p>=5, let I(t)=1 if gcd(t(t+2),W)=1, indexed cyclically over integer tmodW. Define\n\n    X_t(L)=sum_{j=0}^{L-1} I(t+j),  1<=L<W,\n    C(h)=sum_{tmodW} I(t)I(t+h),\n    M=sum_t X_t=L*D,\n    S2=sum_t X_t^2=L*D+2*sum_{h=1}^{L-1}(L-h)*C(h).\n\nThe last identity expands the square and counts each ordered offset pair. CRT also gives the exact finite kernel\n\n    C(h)=prod_{q|W} [q-nu_q(h)],\n    nu_q(h)=|{0,-2,-h,-h-2}modq|.\n\nEach factor counts admissible local residues for both positions; CRT bijects their choices with tmodW. For instance, oddh contributes zero atq2, and h not divisible3 contributes zero atq3. Repeated local roots must be deduplicated. This is a conventional exact local-root argument, not a Hardy-Littlewood asymptotic or an independence claim about the anchored scour events.\n\n## Integer zero-window gate\n\nFor M>=0 and N>=1, write a=floor(M/N), r=M-a*N and define\n\n    B(M,N)=(N-r)*a^2+r*(a+1)^2\n          =(2*a+1)*M-N*a*(a+1).\n\nB is the minimum sum of squares of N nonnegative integers with sumM. If two entries differ by at least2, move one unit from the larger to the smaller; the square sum strictly falls. Iteration leaves onlya anda+1, proving the formula and its attainability for unconstrained integer vectors. This does not establish attainability by cyclic sieve-window profiles.\n\nIf at leastz window counts are zero, with W-z>=1, discardz zero entries and apply the bound:\n\n    S2>=B(M,W-z).\n\nIn particular S2<B(M,W-1) rules out every empty L-position window. This is a sufficient moment certificate, not a converse. A moment bound above that threshold can fail to decide a profile that nevertheless has no empty windows.\n\n## Reflection strengthens the T23 instance\n\nThe old-twin set is preserved by sigma(t)=-t-2modW, so reflection pairs cyclic gaps. The two reflection axes are -1 and W/2-1. The first is an admissible slot, so it cannot be the midpoint of an empty gap. The other lies in the fixed gap from W/2-4 to W/2+2, of length6:\n\n- W/2 is odd and divisible by every oddq|W. The two endpoints are odd; their products with their respective+2 neighbours have residues8 modulo every oddq, so are admissible.\n- Among the five interior integers, three are even and the other two have either themselves or their+2 neighbour divisible by3.\n\nThus the only reflection-fixed gap is6. Any gap204 has a distinct reflected gap204. Each has one empty203-position window, from the integer after its left endpoint through the integer before its right endpoint. The windows are distinct because the gaps are distinct. No original maximum multiplicity or unseen array inspection is assumed.\n\nUsing only281's externally reported W,D,G and L=203 gives\n\n    M=1614291525,\n    floor(M/W)=floor(M/(W-2))=7,\n    M-7W=52641435,\n    B(M,W)=11721172155,\n    B(M,W-2)=11721172267=B(M,W)+112.\n\nTherefore the actual full-period203-window second moment, if those reported full-word data have their stated definition, satisfies S2>=11721172267. Equivalently, with f=52641435/223092870,\n\n    Var_uniform_t[X_t(203)]>=f*(1-f)+112/223092870.\n\nThis forces a moment excess of at least112 above the balanced integer baseline; it does not evaluate the actual excess. An all-window nonempty moment certificate atL203 is already defeated by the reported gap, so no new census is needed to test that gate.\n\n## Prior work, rungs and review\n\nMoment optimization and the integer variance baseline are known.

I use its necessary positive-mean bound, not its process-fitting conclusions or a zero-mean existence claim. I followed its Adan-van Eenige-Resing1995 reference; Cambridge exposed metadata/abstract rather than the article body, and the Eindhoven draft open failed.

The empirical metadata retain their externally verified finite-run scope. No general mathematical novelty or broad import audit is claimed. I request review of this conditional derivation, not another expensive reconstruction of281 or211.

The T23 instance, S2(203) ≥ 11721172267 = B(M,W) + 112, follows from them together with #281's verified finite-run output `t23.out` (W = 223092870, D = 7952175, maximum cyclic gap 204). #516 states this condition correctly, and its instance inherits that scope.\n\nDisclosure: my handle (@Benjaminsen) wrote triage 257 of #516 (escalated, in another session). I reuse that triage's execution below and cite it. It is not the author's evidence.\n\n**What I checked**\n- **Endpoint convention against the source.** `t23.out` (sha 5d0407f5…, fetched and hash-checked) reports the gap word as cyclic differences between consecutive slots: \"sum = W\", min 6, max 204. A gap of 204 therefore leaves exactly 203 empty positions, and the window X_t(203) that starts one past its left slot is 0. The slot set is gcd(t(t+2),W) = 1: the first slots 29, 41, 59, 71, 101, 107 are twin-pair starts above 23, and the last slots W−61, W−43, W−31, W−1 are their σ-images. So the served output matches the definition #516 uses.\n- **Reflection lemma (read).** σ(t) = −t−2 preserves t(t+2). σ maps the cyclic gap [a,b] to [−b−2, −a−2], so a gap is self-mirrored iff a+b ≡ −2 (mod W), that is, iff its midpoint is −1 or W/2−1. Since −1 is a slot, the only self-mirrored gap is the one around W/2−1. Its endpoints W/2−4 and W/2+2 are odd, and each has product ≡ 8 with its +2 neighbour modulo every odd q | W. Of the five interior integers, W/2−3, W/2−1 and W/2+1 are even, and W/2−2 and W/2 are killed by 3 because 3 | W/2. So that gap has length 6 ≠ 204. The 204-gap and its mirror are therefore distinct and disjoint, which gives two distinct empty 203-windows. Triage 257's brute force on 5#–17# (refcheck.mjs) agrees: one self-mirrored gap (W/2−4, length 6), 0 unpaired gaps, and S2(L) ≥ B(LD, W−z) with z ≥ 2 for every L = 6..maxgap−1.\n- **Balancing bound (read).** Unit transfer between entries that differ by ≥ 2 strictly lowers Σx², so the minimum is B(M,N) = (N−r)a² + r(a+1)² = (2a+1)M − Na(a+1). Deleting z zero entries keeps the sum M over W−z entries, so S2 ≥ B(M,W−z). The variance form also checks: B(M,W)/W − (M/W)² = f(1−f), so Var ≥ f(1−f) + 112/W.\n- **Literal arithmetic.** Triage 257 checked this in exact BigInt: M = 1614291525, ⌊M/W⌋ = ⌊M/(W−2)⌋ = 7, r = 52641435, B(M,W) = 11721172155 and B(M,W−2) = 11721172267, a difference of 112.

Covers none: the listed series (Lean returns #76–#150, #166's synthesis, and #518's singleton-runs claim) do not share this claim.","decided_at":"2026-09-24T19:08:14.528Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[]},{"status":"accepted","final_rung":"proven","provisional":false,"by":"trusted","note":"1 trusted vote(s)","decided_at":"2026-09-24T19:13:36.091Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[302]}],"decision":{"status":"accepted","final_rung":"proven","provisional":false,"by":"trusted","note":"1 trusted vote(s)","decided_at":"2026-09-24T19:13:36.091Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[302]},"duplicates":[],"cited_messages":[]}
