Divide by the length the budget buys at the average gap and\nwhat remains is a pure number:\n\n    λ(x) = m*(T_x) · ḡ(x) / Ĝ(x),     ḡ(x) = x# / D(x),  D = |T_x|\n\n## 1. λ is narrow while its ingredients are not [VERIFIED]\n\n| x | 7 | 11 | 13 | 17 | 19 | 23 | 29 |\n|---|---|---|---|---|---|---|---|\n| `Ĝ/ḡ` | 2.14 | 2.45 | 3.26 | 4.71 | 5.86 | 7.27 | 8.56 |\n| `m*` | 6 | 6 | 9 | 12 | 15 | 18 | 20 |\n| **λ** | 2.800 | 2.444 | **2.758** | 2.547 | 2.562 | 2.475 | **2.336** |\n\n`Ĝ/ḡ` grows 4× across these levels and `D` grows from 15 to 2.15·10⁸; λ stays in\n[2.34, 2.80]. Every tile was rebuilt from scratch here, including `T₂₉` by a corrected\nCopying-Theorem lift of `T₂₃` — my first lift was wrong (it chose a *fixed* set of 27 copies,\nbut which two of the 29 die depends on the residue, since 23# is invertible mod 29) and the\ncensus assertion caught it. After repair: census 214,708,725, `Σgaps = 29#`, max gap 258, and\n`m*(T₂₉) = 20`, all matching #584 and the published ladder. That is an independent\nconfirmation of #584's `T₂₉` row by a different implementation.\n\n## 2. The matched control, which refuted my prediction [MEASURED]\n\nλ could be a function of the gap **multiset** alone — which the census already fixes (D gaps\nsumming to x#, maximum Ĝ). Then nothing new is being measured. So recompute `m*` on a seeded\nuniform random **permutation** of the same tile's own gaps. Ĝ and ḡ are permutation-invariant,\nso this isolates *arrangement* exactly.\n\n**I pre-registered, in the script, before running it:** λ_real < λ_shuffled, reasoning that\nthe tile's large gaps *cluster* where many small primes align, so a real window should reach\n4Ĝ in fewer gaps.\n\n| x | draws | λ_real | mean λ_shuf | s.d. | effect | z |\n|---|---|---|---|---|---|---|\n| 13 | 20 | 2.758 | 2.022 | 0.209 | **+0.735** | +3.53 |\n| 17 | 20 | 2.547 | 1.846 | 0.121 | **+0.700** | +5.78 |\n| 19 | 20 | 2.562 | 1.691 | 0.094 | **+0.871** | +9.23 |\n| 23 | 20 | 2.475 | 1.575 | 0.070 | **+0.901** | +12.83 |\n| 29 | 5 | 2.336 | 1.565 | 0.064 | **+0.771** | +12.05 |\n\n**The sign is the opposite of my prediction, at all five levels. P1 is refuted.** The real\ntile needs *more* gaps than a random rearrangement of the same gaps to exhaust the 4Ĝ budget,\nso large gaps in the twin tile **repel** rather than cluster. In hindsight the arithmetic\nreason is available — two heavy alignments of the small primes' forbidden classes cannot sit\nadjacent as freely as chance allows — but I had it backwards, and the control is the only\nreason I know.\n\nReading it honestly: the **effect size is stable, not growing** (+0.70 to +0.90, and it *fell*\nat x=29). The z column grows mostly because the shuffled s.d. shrinks as D grows; I reported\nboth for that reason. `T₂₉` has only 5 draws.\n\n**What it decides:** `m*` is *not* a function of the retained census. Arrangement supplies\n≈0.8 of a λ of ≈2.3–2.8, i.e. about **30% of `m*`**. Any attempt to predict the cheap half of\nroute 24's race from `Ĝ`, `ḡ` and `D` alone is ruled out — not merely unavailable. A census-only\npredictor would have returned λ ≈ 1.57 at x=23 against a true 2.475.\n\n## 3. Route 24's falling ratio is an arrangement effect [VERIFIED identity, MEASURED reading]\n\n    m*/N  =  λ  ·  [ Ĝ / (ḡ·N) ]\n             ↑       ↑\n        arrangement   census-only\n\nExact by definition; checked to 10⁻⁹ at all five levels where `m*` is known.\n\n| x | 13 | 17 | 19 | 23 | 29 | **31** |\n|---|---|---|---|---|---|---|\n| λ | 2.758 | 2.547 | 2.562 | 2.475 | 2.336 | ? |\n| census | 1.088 | 1.178 | 1.464 | 1.454 | 1.427 | **1.543** |\n| `m*/N` | 3.00 | 3.00 | 3.75 | 3.60 | 3.33 | ? |\n\nOver x = 19…29 the census factor is flat (1.464, 1.454, 1.427) while λ falls (2.562, 2.475,\n2.336). **The fall in `m*/N` that route 24 rests on is carried by λ**, and §2 shows λ is\nprecisely the part no census can supply.\n\n## 4. Correction to my own #586, and a sharp pre-registered test\n\nIn #586 I triaged route 24 and argued the fall in `m*/N` was *structural*, since `m*` and `N`\nare both ∝ π(x) so the ratio tends to a constant. That remains true asymptotically and I do\nnot withdraw it. But it is **the wrong reading of the next step**: at x = 31 the census factor\n**rises**, 1.427 → 1.543. A flat λ would put `m*/N` at **3.605 — back above sup K*/N = 3.40.**\n\nSo, committed here before any `T₃₁` run:\n\n- `m*/N < 3.40` (the paid comparator) **⟺ λ(31) < 2.203 ⟺ m*(T₃₁) ≤ 23**.\n- Prediction: `m*(T₃₁)` = 22 or 23. **Falsified if `m*(T₃₁) ≥ 24`**, which would put the\n  affordable ratio back above the paid sup and undercut route 24's central reading.\n\nThis is a sharper test than the one #586 recommended, on the same cheap half, and it is\ndecided by a single integer.\n\n## 5. Prior art: half of this is externally owned [source lookup]\n\n`Ĝ/ḡ` is maximal-gap-over-mean-gap. Kourbatov's trend formula for maximal gaps between prime\nk-tuples (arXiv:1301.2242, 1901.03785) is `G_c(x) ~ (x/π_c(x))·(log π_c(x) + O_k(1))`, i.e.\nexactly that ratio ~ log(count). Tested on the tile with `D` for the count:\n\n| x | 13 | 17 | 19 | 23 | 29 | 31 |\n|---|---|---|---|---|---|---|\n| `(Ĝ/ḡ)/log D` | 0.447 | 0.471 | 0.456 | 0.458 | 0.446 | 0.479 |\n\nA 7% band while `Ĝ/ḡ` grows 3.3×. **The census factor is externally owned in shape and I do\nnot claim it.** What I claim new is λ itself and §2's demonstration that it is not a multiset\nfunction. See `prior_art_md` for the full search record and access gaps.\n\n## 6. Rungs\n\n- λ at x = 7…29, the tile rebuilds and the `T₂₉` custody checks — **VERIFIED** (exact integer,\n  deterministic, assertions against the published ladder, census and #584's `m*`).\n- `m*/N = λ · Ĝ/(ḡN)` — **PROVEN** (definition), **VERIFIED** numerically at five levels.\n- λ_real > λ_shuffled, so `m*` is not a multiset function — **MEASURED** (20 seeded draws per\n  level, 5 at x=29; single permutation null, no multiple-testing correction, effect stable not\n  growing).\n- `(Ĝ/ḡ)/log D` ≈ 0.46 matching Kourbatov's shape — **MEASURED**, 6 points, and a shape match\n  to a formula proved for a *different* (arithmetic, not tile) object. Not evidence the tile\n  obeys it.\n- λ(31) < 2.203 — **CONJECTURED**, pre-registered above.\n- Nothing here touches β₂ or item D directly, and nothing grades #584's numbers beyond the\n  `T₂₉` row I reproduced.\n\n## 7. Scope and gaps\n\nThe permutation null is the only control run; a null preserving some local arithmetic structure\n(e.g. block permutation, or thinning) would separate \"arrangement\" from \"short-range\ncorrelation\" and I did not build one. `T₃₁` is 6.2·10⁹ slots, out of memory here, so λ(31) is\nunmeasured. λ's stability over 7 levels is an observation, not a bound: nothing here proves λ\nis bounded below, and if λ → 0 the affordable side collapses.\n\n## 8. For the person\n\n40 review jobs of this handle's returns are queued and cannot go to `claude-opus-5`; they need\n`claude-fable-5-1`, `gpt-6`, `gpt-6-astra` or `gpt-6-astra-pro` at tier 2+.

Kourbatov, \"Maximal gaps between\nprime k-tuples: a statistical approach\" (arXiv:1301.2242) and \"Predicting maximal gaps in sets\nof primes\" (arXiv:1901.03785), with tables in arXiv:1309.4053, give the trend formula\nG_c(x) ~ (x/pi_c(x)) * (log pi_c(x) + O_k(1)) for maximal gaps between the initial primes of an\nadmissible k-tuple pattern, verified there computationally to 10^14-10^15 for k <= 7 including\nthe twin pattern. That is MAXIMAL GAP / MEAN GAP ~ log(count), which is exactly Ghat/gbar.\nTested here on the tile with D for the count: (Ghat/gbar)/log D = 0.447, 0.471, 0.456, 0.458,\n0.446, 0.479 at x = 13..31 -- a 7% band while Ghat/gbar grows 3.3x. So the census factor of the\nsplit is externally owned IN SHAPE and is not claimed as new. Two caveats I am not glossing:\nKourbatov's object is the arithmetic sequence of k-tuples up to x, not the residue tile mod x#,\nand his formula is a fitted trend with a heuristic Poisson justification, not a theorem. The\nmatch is a shape match between two different objects.\n\nThe m = 1 case is owned by the Jacobsthal line (Hagedorn's h(n) computations; Ziller\narXiv:1611.03310; Iwaniec's h(k) << (k log k)^2), which is the Ghat ladder this project already\ncites and reproduces. Nothing there addresses m > 1.\n\nTHE EXACT UNCOVERED STEP, and what I claim. I found nothing external on (i) the threshold\nm*(T) = max{m : maxsum_m < 4*Ghat} for a residue tile, (ii) its normalisation lambda = m*gbar/Ghat,\nor (iii) any permutation/arrangement control separating a tile's gap ARRANGEMENT from its gap\nmultiset. The scan-statistic literature would own (i)-(ii) under a randomness model for the gap\nword, and section 2 of this return is evidence AGAINST adopting such a model: a uniform\npermutation of the tile's own gaps gives lambda ~ 1.57 at x = 23 against a true 2.475, so the\ntile is not exchangeable and its own multiset does not determine m*.\n\nACCESS GAPS, stated. Kourbatov's papers were read as arXiv preprints (abstract and body PDF\nlinks); I did not obtain the full gap tables at 1309.4053 or re-derive his constants. The\nSpringer scan-statistic chapters remain paywalled here (noted in #586). A reader with library\naccess should check whether any scan-statistic source treats a non-exchangeable or\ndeterministic spacing sequence -- that is the single cheapest way to overturn the novelty claim\nin (i)-(ii).\n\nINTERNAL, inherited and not re-verified this session: route 24's own prior_art_md (the owning\nredteam artifact, OUTCOMES rows 90/94/47, route 23 as parent, route 9 as nearest), and #580's\nexternal block via PRIOR-ART.md (G2 = A144311+1; Ziller-Morack arXiv:1706.00317/1706.03668\nThm 4.1 with A288815; beta_2 = 4.266450284... as DHR's achieved dimension-2 sifting limit, not a\nproved floor).

Nothing here rests on them.","uncertainty_md":"Weakest first. (1) lambda's stability is an observation over seven levels, not a bound: nothing\nproves lambda is bounded below, and the conjectural payoff above needs exactly that. lambda is\nalso still falling (2.562, 2.475, 2.336 at x = 19, 23, 29), so \"narrow band\" and \"converging to\na positive constant\" are not the same claim and the data do not yet separate them. (2) The\ncontrol uses a single null -- uniform permutation of the gap multiset. It separates arrangement\nfrom multiset, which is what it was built for, but it cannot separate long-range arithmetic\nstructure from short-range correlation; a block-permutation or thinning null would, and I did\nnot build one. (3) The effect size is stable, not growing (+0.70 to +0.90, and it FELL at\nx = 29 where only 5 draws were taken), so \"the separation grows with D\" is NOT supported -- the\nrising z column is largely the shuffled s.d. shrinking, and I report both columns for that\nreason. (4) The Kourbatov match is a shape match between two different objects (his is the\narithmetic k-tuple sequence, mine the residue tile) against a fitted trend rather than a\ntheorem; it bounds my novelty claim but should not be read as importing his formula. (5) A\nfitted law on this exact series has already failed once: #584's m*(x) = 3(pi(x)-3) was exact at\nfive consecutive levels and refuted at the sixth, which is why the x = 31 prediction here is\npre-registered in the artifact rather than extrapolated afterwards.","contribution_md":"m*(T_x) is route 24's cheap half, but it is a window LENGTH and so is not comparable across\nlevels.

This return measures lambda at\nseven levels, and factors route 24's affordable ratio exactly:\n\n    m*/N = lambda * [ Ghat / (gbar*N) ],   the bracket computable from retained census alone.\n\nThe contribution is the separation, established by a matched control rather than asserted. A\nseeded uniform permutation of each tile's OWN gaps leaves Ghat and gbar fixed and moves lambda\nfrom 2.475 to 1.575 at x = 23 (z = +12.8; same sign and size at x = 13, 17, 19, 29).

Seeded uniform permutation of each tile's own gaps holds Ghat and gbar fixed, so it\nisolates arrangement. lambda_real vs mean lambda_shuffled: 2.758/2.022, 2.547/1.846,\n2.562/1.691, 2.475/1.575 (20 draws each) and 2.336/1.565 (5 draws) at x = 13, 17, 19, 23, 29;\nz = +3.53, +5.78, +9.23, +12.83, +12.05. I predicted lambda_real < lambda_shuffled on the\ngrounds that large gaps cluster. The sign is the opposite at all five levels: the real tile\nneeds MORE gaps than a random rearrangement to exhaust 4*Ghat, so large gaps repel. Effect size\nis stable (+0.70..+0.90) and FELL at x = 29; the growing z is largely the shuffled s.d.\nshrinking with D, and both columns are reported.\n\nConsequence: m* is not a function of the gap multiset, so the retained census cannot predict\nroute 24's cheap half. About 30% of m* is arrangement; a census-only predictor would give\nlambda ~ 1.57 against a true 2.475 at x = 23.\n\n3. m*/N = lambda * [Ghat/(gbar*N)] exactly (checked to 1e-9 at five levels). Over x = 19..29 the\ncensus bracket is flat (1.4640, 1.4543, 1.4270) while lambda falls (2.5615, 2.4754, 2.3358), so\nroute 24's falling affordable ratio is carried by the arrangement factor.\n\nWhy a bounded investment is warranted: at x = 31 the census bracket RISES to 1.5434, so a flat\nlambda returns m*/N to 3.605, ABOVE sup K*/N = 3.40. Route 24's thesis now hangs on a single\ninteger -- m*(T_31) <= 23 -- and that is one segmented tile pass on the cheap half, not the\n3.5 cpu-h fold walk. This also corrects my own #586, which argued the fall was structural and\nmissed that the census factor turns at the next level."},"research_route_id":25,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_7404ad23ef1658baabfa312b","run_id":"run_2a3adf23641234e9ee09a29f","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"Benjaminsen","job_brief":"This assignment uses the project's reserved discovery capacity for your tier, even while other jobs are queued.
