The retained originalx19half-word is still missing: fresh ask6 is open without answers. I return a frozen source-gated design and a finite model argument, author-Proven only for that displayed argument and toy, with manual review requested. Pearson permutation-trend methods are known; no statistical novelty, arithmetic exchangeability, exponent or infinitude theorem is claimed.\n\n## Decision and fixed input\n\nThe finite question is whether zero-run lengths increase in ordinal order as the canonical lower half approaches its central gap. Those runs contain gaps at or below24. A positive signal would justify examining an oriented gradient in run sizes rather than just neighbouring size clustering; failure stops this positive-gradient direction. The score is in run index, not a regression against physical residue distance.\n\nReuse428/511/518/523's copiedx19convention: full marked gap word(U,6,reverse(U)), halfH189337, labelsB_i=1{U_i>24}, equality0, N0=107516,N1=81821. These are external retained counts with pending positional custody, not a reproduced census. Freeze the original increasing-position half orientation toward the central6; reversing or rotating it after observing the score is prohibited. Both endpoints, actual run lists and actual n remain unknown.\n\nExtract zero-run lengths in half order and remove the first and last zero runs. If these are the same sole run, no eligible interior list remains. Keep the entire ordered one-run list fixed, the original alternating colors and the endpoint zero-run lengths. Uniformly permute the n labeled interior zero lengths. Duplicate lengths have the same product of multiplicity-factorial preimages, so distinct length orderings are uniform. This S_n action preserves both color run-length multisets, label counts, endpoint labels/run lengths,511's reflected cyclic switch count and518's singleton score. It does not condition on523's neighbouring-product score Q, and I do not claim a signal independent of Q after conditioning on Q.\n\n## Finite score and exact reference\n\nFor n>=2 and a nonconstant interior list l, put\n\n    y_i=n*l_i-sum_j(l_j),   w_i=2*i-n-1,   1<=i<=n\n    P2=sum_i(y_i²),   Sw2=sum_i(w_i²)=n(n²-1)/3\n    C=sum_i(w_i*y_i)\n    Utrend=C/sqrt(P2*Sw2),   Z=sqrt(n-1)*Utrend.\n\nUtrend is the usual Pearson correlation of ordinal position and raw run length, not rank correlation. Under the fixed-multiset uniform labeled permutation, E(y_pi(i))=0, E(y_pi(i)²)=P2/n and for i!=j, E(y_pi(i)y_pi(j))=-P2/[n(n-1)]. Both w and y sum to0. Therefore\n\n    E(C)=0\n    Var(C)=(P2/n)*Sw2 + [-P2/(n(n-1))]*[-Sw2]\n          =P2*Sw2/(n-1)\n    E(Utrend)=0,   Var(Utrend)=1/(n-1).\n\nThis is an elementary finite permutation derivation, not an imported normal limit or fitted control variance. Cauchy-Schwarz gives |Utrend|<=1 and |Z|<=sqrt(n-1). Thus a four-sigma descriptive threshold is reachable only when n>=17. The future gate requires n>=17 and P2>0; a missing/constant/small list is stopped as undefined or insufficient, never reported as score0.\n\nThe effect scale is explicitly Utrend>=4/sqrt(n-1). At illustrative n50000 it is about0.018; that is not an observed n or a power calculation. The copied counts give only n<=81820, since at mostN1+1zero runs can alternate withN1one labels before deleting two endpoint zero runs. They do not determine n, P2 or the true effect. No Gaussian tail probability is attached to four sigma.\n\n## A toy separating trend from the retained scores\n\nUse a binary half with zero-run lengths(2,2,3,4,5,2) and five intervening one runs all of length2. Compare its reverse, whose zero lengths are(2,5,4,3,2,2). Both halves have28labels,18zeros,10ones, endpoints0,10internal switches and no singletons; endpoint runs and both run multisets agree. Interior lists(2,3,4,5) and(5,4,3,2) give y=(-6,-2,2,6) and its reverse; w=(-3,-1,1,3), P2=80, Sw2=20, C=40/-40 and Utrend=1/-1. Both have523's Q=sum y_i*y_(i+1)=20. Reversal preserves Q in general but flips C because w_(n+1-i)=-w_i.\n\nMap0 to gap24 and1 to gap30, keep central6 and reflect. Both generic full words have histogram{6:1,24:36,30:20}, A1=30,A2=60,511fullswitch count20 and518singleton score0, while their signed trends differ. The 28-label toy is a hand construction, not an executed enumeration or arithmetic wheel. Its n4is below the future eligibility gate and neither toy is claimed to meet the decision threshold.\n\n## Frozen falsifier, matched controls and cost\n\nAttached prereg1221.json fixes one source/half/cutoff, the positive tail, exactly99controls and seed1221001. A future CPython3.12 implementation will use random.Random(seed).shuffle on a fresh labeled baseline for each draw, with replacement. Each control fixes the ordered one runs and endpoint zero runs. The group assumption for this model is explicit; it is not supplied by a zero Pearson population correlation alone, nor proved for the actual deterministic wheel.\n\nReport the tie-conservative rank diagnostic q_rank=(1+#{control C>=observed C})/100. Hemerik/Goeman's primary §2.1 and§3.3 Definition2/Theorem2 (both proofs inspected), plus§3.4, explain the transformation-group/invariance requirement and inclusion of the observation for finite random-permutation tests. Their conditional-model validity does not make the arithmetic sequence exchangeable. [Primary](https://link.springer.com/article/10.1007/s11749-017-0571-1).\n\nContinue this positive-gradient direction only if Z>=4 and q_rank<=0.05. Stop it if Z<=2; all other outcomes are inconclusive. A negative extreme falsifies the chosen positive alternative. It is not relabeled a successful negative-gradient discovery. No extra draws, subset/balanced permutation selection, half reversal, threshold adjustment or secondary score search after viewing results. The mean-control guard is |mean C|<=5*sqrt(Var(C)/99); failure stops instrument investigation without redrawing. All99draws must finish, else report failure/inconclusive rather than significance from a partial batch.\n\nThe future implementation must freeze source/code/prereg identities before execution and check direct/reduced baseline scoring, multiset/endrun/ordered-one/R/S preservation and the reversal sign law. Only then can it run. The present design has no implemented checker or verification_plan. Its resource cap is180CPU seconds, one thread,128MB RAM,64MB disk with15minutes separate judgment; work O(H+99n), one control list retained at a time. This is a cap, not measured runtime. No new route or admission retry while source custody is absent. Existing request1642/ask6 is reused without duplicate asks or regeneration.\n\n## Prior work and remaining scope\n\nZhou/Wright's2012UNC working-paper31 primary abstract identifies permutation Pearson correlation as a common trend/regression statistic. Its download returned403, so no full-body formula or approximation theorem is imported. [Primary record](https://biostats.bepress.com/uncbiostat/art31/). The exact model calculation above is supplied directly, with no novelty claim. Pending523's established successive-product diagnostic and source-gated control record are reused and freshly matched.\n\nTomás Oliveira e Silva's primary twin-gap page reports actual-prime gap counts/first occurrences through endpoint10^16. I read the introduction/results landing page, not its compressed table or sieve code. That is a different object and published summary; it does not furnish this selected fixed-wheel marked half-word. No table was regenerated or substituted for the missing order. [Primary dataset description](https://sweet.ua.pt/tos/twin_gaps.html).\n\nFresh511/518/523/428/438reports match their earlier complete actual readings; central definitions reread.

Prior-art1221.md records queries and access gaps, including one combined truncated output without a full-body-reading claim.\n\nOnly the finite definition, conditional sampling/reference proof, reversal toy and reachability bound are offered for manual review.
