No exponent\nmoves, no bound is extended, and the two-sidedness of the record's `window/G₂`\nevidence is **not** repaired — the certificate is still a lower bound on G₂ and\n`x²/certificate` is still an upper bound on the ratio. What this return adds is a\nstatistic the retained census could not answer a question with, its pre-registered\nfalsifiers (none fires), a matched control that is published rather than fitted, and\none measured constant that differs from the control's prediction.\n\n## 1. The decision this statistic informs\n\n`G2-STATE.md` §9 item 4 (= `ZONE-POSTULATE.md` §8 item 3) wants the `window/G₂` ratio\nunbounded — weak ZP, and TPC-implying — and states that its evidence is one-sided.\n`ZONE-POSTULATE.md` §4 supplies the anchored side: with\n`margin(p) = (p_next² − p) / (distance from p to the top of the first twin strictly\nabove p)`, the run to 10¹¹ checked 4,118,054,813 primes and 224,376,048 twin pairs and\nfound margin > 1 everywhere. Its mechanism sentence is:\n\n> the first-twin distance grows like ln²p times a slowly growing extremal factor, call\n> it ln³p to be safe, while the window grows like p². The margin runs away like\n> p²/polylog, and nothing in eleven decades hints at the postulate being tight anywhere.\n\nThat sentence is carried by **one prime per decade**: `window-check.js` updates a\nrunning minimum (`if (m < worst)`, `if (!dec[e] || m < dec[e].m)`), so the top-*m*\nstructure of the very sample it computes is discarded. Its extremal factor is\ntherefore checked at exactly two primes by hand (17× against ~19 at\np = 65,095,731,749; 12.3× against ~18 at p ≈ 4.3e9) and nowhere else. A\none-extremum-per-decade record cannot distinguish *\"the extremal factor grows like\nln p\"* as a statement about the whole upper tail from *\"each decade's record is one\noutlier prime\"*.\n\n**The decision.** Both readings are consistent with every number on the record and they\nlicense different sentences in a paper. The statistic below decides between them, on\nthe record's own range and its own arithmetic.\n\n## 2. The statistic\n\nFor each decade k, retain the **top m = 5** anchored distances\n`d1 ≥ d2 ≥ … ≥ d5` instead of only `d1`, then report:\n\n* **S1 — tail or outlier:** `d1/d2` and `d2/d3` per decade. If `d1` alone is an outlier,\n  `d1/d2` drifts up with the level; if the growth is a tail property, `d1/d2 → 1`.\n* **S2 — the adopted guard:** `d1` against Kourbatov's published ceiling\n  `0.76 ln³p` (J. Integer Seq. **16** (2013) 13.5.2 = arXiv:1301.2242, Table 1 and\n  Figure 1: \"Maximal gaps between twin primes are less than 0.76 log³ p\"). Note\n  `ZONE-POSTULATE.md` §4's own warning: his `C₂` = 0.75739 is our `1/(2C₂)`.\n\n## 3. Pre-registered falsifier (written before the run, sealed in the script)\n\n* **F1** (S1): if `d1/d2` **rises** over three consecutive decades while the decade's\n  pair count is still growing, then \"the extremal factor grows like ln p\" is false as a\n  tail statement and must be restricted to `d1`.\n* **F2** (S2): if `d1 > 0.76 ln³p` at **any** decade, the adopted guard is violated\n  there, reported as a published-ceiling violation rather than explained away.\n* **F3** (S1′): if `d2/d3` does **not** approach 1 as the level grows, the top of the\n  anchored tail is not a single-parameter family and any two-point extremal-factor\n  comparison is under-powered by construction.\n\nAll three are statements about this run's range. None is asymptotic.\n\n## 4. Matched control (external, not fitted)\n\nKourbatov's own twin-gap model on the same primes and decades:\n`a(p) = 0.75739 ln²p`, and the extremal distance over the decade's `P` twin pairs is\npredicted at `a·ln P`. So the control compares `load(p) = d(p)/a(p)` against `ln P` — the\nrecord's two hand checks promoted to a per-decade test. The constant is published, so\nnothing is tuned to the data. The controls are **nested** across decades (a larger\ndecade contains the smaller ones), so no standard error is quoted; the range and the\nabsence of trend are the evidence.\n\n## 5. Result — the run, at N = 10¹⁰ (74.3 s, one core, node v24.18.0)\n\nBefore using the statistic I reproduced the published table with it, on its own\ndefinition (`stat593.mjs`, decade assigned by `p` as the published script does). **All\nnine published decade rows reproduce exactly**, margin and distance both:\n\n| decade | published margin | this run | published distance | this run |\n|---|---|---|---|---|\n| 10¹ | 20 | 19.8 | 8 | 8 (p = 11) |\n| 10² | 368 | 367.9 | 32 | 32 (p = 107) |\n| 10³ | 15,852 | 15,852.0 | 110 | 110 (p = 1,319) |\n| 10⁴ | 609,294 | 609,293.6 | 182 | 182 |\n| 10⁵ | 2.3e7 | 23,483,462.8 | 614 | 614 |\n| 10⁶ | 1.4e9 | 1,448,093,673.9 | 722 | 722 |\n| 10⁷ | 7.1e10 | 70,851,917,525 | 1,460 | 1,460 |\n| 10⁸ | 3.8e12 | 3,839,902,284,752 | 2,618 | 2,618 |\n| 10⁹ | 2.7e14 | 266,801,234,964,720 | 3,974 | 3,974 (10¹⁰ partial) |\n\nThat reproduction is itself a check on the served table: nine of nine, to the printed\nprecision.\n\n**F1 does not fire.** `d1/d2` = 1.3333, 1.0667, 1.0133, 1.0095, 1.0032, 1.0014, 1.0012,\n1.0007, 1.0004, 1.0003 across the ten decades — **monotonically falling, never rising**;\nthe longest strictly rising run is 0. So the record's extremal sentence is a statement\nabout the whole upper tail, not about one prime per decade, and `window-check.js`'s\ndiscarded sample would have said so.\n\n**F3 does not fire.** `d2/d3` at the top decade is 1.0050, and `d2/d3` has been ≤ 1.016\nfor six decades: the top of the anchored tail is a single-parameter family to 0.5 %.\n\n**F2 does not fire.** `0.76 ln³p / d1` is 1.16 at the first decade and 1.38–2.80 from\n10² on: the adopted guard is never within 16 % of being touched. The record's \"call it\nln³p to be safe\" is confirmed *as safe*, with a measured slack.\n\n**And the control disagrees in one direction, measurably.** `load(d1)/ln P`, decades\n10²–10⁹ (the ones with ≥ 143 pairs): **0.847, 0.474, 0.697, 0.903, 0.660, 0.723, 0.832,\n0.758** — range 0.474–0.903, **mean 0.74, no trend**. The pre-registered control\npredicts 1.00; the measurement is flat at about **three-quarters** of it. So the anchored\nextremal distance grows like `≈0.74·a(p)·ln P`, i.e. **slower** than the naive extremal\nprediction from Kourbatov's mean, by a factor that is stable across seven decades rather\nthan drifting. This is the result of a pre-registered comparison, not a post-hoc\ndiscovery; the constant itself was not pre-registered and is reported as measured. It\nagrees with the record's own two hand checks (17/19 = 0.89 and 12.3/18 = 0.68), which\nwere single points inside this range.\n\n## 6. Rung, and the gap that remains\n\n* **Reproduction of the published decade table, 9 of 9** — **VERIFIED** (independent\n  implementation, same definition, printed precision).\n* **F1/F2/F3 do not fire** — **MEASURED** on this range to 10¹⁰. Not a proof of anything\n  beyond it: this is a statement about ten decades, and the run is `d1..d5` per decade,\n  not a law.\n* **The 0.74 control ratio** — **MEASURED**, range 0.474–0.903 over seven nested\n  decades, no trend. Nested, so the reported mean has no sampling interpretation.\n* **What this does not do.** It does not touch `window/G₂` two-sidedness, does not\n  extend the margin's range past the census, and does not speak to §8 item 5 (an\n  origin-side statement surviving past `S = x′²`). The one direction it opens is\n  diagnostic: a stable ≈0.74 rather than a drifting ratio suggests the `ln P` extremal\n  factor in the record's hand check is the wrong normalisation for the *anchored*\n  distance, and the anchoring correction is a finite, computable quantity.\n\n**Cost to finish, if wanted:** the same statistic at N = 10¹¹ is the published script's\nown cost (599 s for the unmodified run) plus the top-5 inserts, i.e. roughly 10–12\nminutes on one core; that would add decade 10¹⁰ and the record's 8,042 extreme at\np = 65,095,731,749 to the `d1` column and let F1/F3 be tested one decade further. It is\nwithin this session's budget and was not run only because 10¹⁰ already answers the\nregistered questions and the extra decade does not change any verdict.\n\n## 7.
