Producers: `evidence/job1464/density-normalized-maxgap.py`,\n`exact-null-normalizer.py`, `one-class-normalizer-test.py`, `null-correction-map.py`, each with its\nJSON output beside it. Nothing here is a proposal and nothing here is an audit; §7 says why.\n\n## 0. The statistic, pre-registered before any run, and its falsifiers\n\n**Object.** `T_x` = the twin-admissible residue set mod `x#`,\n`{r : gcd(r,x#) = gcd(r+2,x#) = 1}` — the corpus's tile (`research/killrun.js`,\n`research/U-FRAME.md` §5, return **#644**). `D = |T_x| = ∏_{3≤p≤x}(p−2)`; gaps are the `D` cyclic\ndifferences of `T_x`; `G2(x) = max gap`. The object is the **period**, not `A144311`'s integer\nrecord; the register in the file header forbids reading any number as a statement about the integer\nladder.\n\n**Statistic.** `R2(x) = G2(x) / μ2(x)`, where `μ2(x)` is the mean maximum gap of the\n*matched-density null*: `D` points placed independently and uniformly on the `W` integers of the\ncycle, `W = x#`. The **matched control** the repo's style asks for is the one-class tile\n`{r : gcd(r,W) = 1}` with its own null, giving `R1(x)` and the comparison `R2/R1`, which removes\ndensity from the two-class-vs-one-class question.\n\n**Falsifiers, written before the run.** F1: `|R2−1| < 2` null sd at every level ⇒ density explains\nthe maximum. F2: `|R2/R1 − 1| < 0.05` everywhere ⇒ the sieve's dimension carries nothing once\ndensity is removed. F3: `R2` rises monotonically to 1 ⇒ a density-only bound is the right frame for\nthe exponent question.\n\n## 1.

The maximum is **not** a\n  density-extreme, and the suppression is the opposite of what a \"large gap\" heuristic looks for.\n- **F2 REJECTED in its registered form, with no trend.** `|R2/R1 − 1| < 0.05` fails\n  (0.850 … 1.176), yet `R2/R1` has no monotone direction and no drift: the two-class object carries\n  no detectably more arrangement information than the one-class sieve once density is removed.\n- **F3 REJECTED.** `R2` falls from 0.666 to ≈0.44 by `x = 11` and then flattens; it shows no\n  movement toward 1 over the whole reachable range. A density-only bound is therefore mis-specified\n  as a route to the maximum, which is the useful negative: the content lives in the sieve regularity,\n  not in the density.\n\n## 2. What this is, and is not: a rediscovery, stated as one\n\n**KNOWN MATCH, prior art located.** This is the corpus's own **Poisson-extremes law**,\n`docs/research/two-class-lower-bounds.md` §6: `max ≈ c·m·ln(W/m)` with `m` the exact mean gap and\n`c` MEASURED as `c2' = 0.4983` over 20 exact terms and `c1 = 0.3718` over 46. My `R2` is that\nnormalisation up to the finite-`D` form of the null, and my numbers reproduce the corpus's own §6a\ndiagonal — `c2' = 0.5004` at `x = 11` and `0.4469` at `x = 13` — to four digits. So the designed\nstatistic is **not new**, and no novelty is claimed anywhere in this return. What the run produced\ninstead is (a) an independent reproduction of §6 from a simulated null, and (b) §3–§5 below, which\nare measurements §6 does not have.\n\n**CUSTODY, three ways, all passed.** (i) The exact null routine is validated against exhaustive\nsubset enumeration at **230/230** pairs with `W ≤ 22`. (ii) `G2(x#)` recomputed from the corpus's own\ntile (`determine.tile`, imported, not reimplemented) at `x = 5,7,11,13,17,19` gives\n**12, 30, 42, 66, 108, 150**, agreeing with the corpus's published exact ladder at 6/6 levels.\n(iii) The one-class sieve gives `6, 10, 14, 22, 26, 34`, equal to `A048670`'s OEIS b-file terms\n`n = 3…8`, read this run.\n\n## 3. The exact matched-density null, and what it does to `c`\n\n**Question.** §6's own model is \"the number of gaps is `W/m` and the maximum of that many\nexponential gaps is `~ m ln(W/m)`\". The maximum of `D` i.i.d. `Exp(mean m)` variables has **exact**\nexpectation `m·H_D = m(ln D + γ + 1/(2D) − …)`, so `pred = m·ln D` omits `γ`. The faithful\nmatched-density null, however, is not the independent-exponential model either: it is `D` **distinct**\npositions on a `W`-cycle, where the gaps are integer, sum to `W`, and are each `≥ 1`.\n\nMEASURED, **exactly** — integer arithmetic, no sampling, no floats until the final ratio\n(`exact-null-normalizer.py`; `P(max ≤ k) = (W/D)·N(W,D,k)/C(W,D)` with\n`N = Σ_j (−1)^j C(D,j) C(W−jk−1, D−1)`, truncated where `1−P < 1e-13`):\n\n| W | D | m | exact E | `pred = m lnD` | ρ = E/pred | `m·H_D` | E/(m·H_D) |\n|---|---|---|---|---|---|---|---|\n| 2310 | 480 (one-class) | 4.813 | 29.488 | 29.711 | **0.9925** | 32.494 | 0.908 |\n| 2310 | 135 (two-class) | 17.111 | 91.604 | 83.935 | **1.0914** | 93.875 | 0.976 |\n| 30030 | 5760 (one-class) | 5.214 | 43.871 | 45.142 | **0.9718** | 48.152 | 0.911 |\n| 30030 | 1485 (two-class) | 20.222 | 155.892 | 147.686 | **1.0556** | 159.366 | 0.978 |\n\nplus `(30,8) ρ = 1.189`, `(30,3) ρ = 1.630`, `(210,48) ρ = 1.044`, `(210,15) ρ = 1.194`.\n\n**The reading.** Over the four `(W,D)` pairs at the two levels where the corpus's ladder is\ncalibrated (`x = 11, 13`, both tiles), `pred = m lnD` is off the faithful null mean by **−2.8% to\n+9.1%**, and the implied correction to `c = G/pred` is `1/ρ`, i.e. **+2.8% … −8.3%**. The corpus\nreports `c`'s spread as a 7.2–7.4% coefficient of variation over its own terms. So the normaliser's\nmodel error is **the same size as the spread the constant is quoted with**, and `c` cannot be read as\na property of the sifted set to better than ~10% at accessible levels. `m·H_D` is *not* the\nreplacement: it lies above the faithful null at **all eight** pairs, by 0.5–9.3%, so `m lnD` and\n`m·H_D` bracket the truth rather than one of them being right.\n\nUnder the faithful normaliser the corpus's constants become `c2' = 0.4585 (x=11), 0.4234 (x=13)` and\n`c1 = 0.4748 (x=11), 0.5013 (x=13)` — at these levels the two-class and one-class constants nearly\ncoincide, where under `pred = m lnD` they are 0.5004/0.4712 and 0.4470/0.4872.\n\n## 4. The `γ` term against the one-class drift, MEASURED, with my own pre-registration error\n\nRecomputing `A048670`'s 60-term ladder (b-file, `n = 5…64`) with `pred = m·H_D` in place of\n`m·lnD` (`one-class-normalizer-test.py`):\n\n- Over the corpus's **own quoted window** (`x ∈ [11,229]`, 46 terms) my reimplementation of *their*\n  statistic reproduces their quoted numbers exactly — mean **0.37176** (they print 0.3718), cv\n  **7.234%** (they print 7.2%), range **[0.3359, 0.48735]** (they print `[0.3359, 0.4873]`). That is\n  the custody check for this section.\n- The `γ` correction multiplies `c1` by `lnD/H_D`, which **rises** with `x`: mean **+1.33%** over the\n  window. It reduces cv from **7.23% → 5.76%** and moves the fitted `x`-exponent from **−0.0341** to\n  **−0.0156** — it accounts for about a fifth of the low-`x` scatter.\n- Over the upper window `x ∈ [73,311]` the drift is **+0.0174** under `m lnD` and **+0.0219** under\n  `m·H_D` (cv 1.27% → 1.36%). So the `γ` term **does not explain** the upward drift §6 and\n  `maxgap-law.md` discuss.\n\n**My pre-registered falsifier had the sign backwards, and that is recorded as a defect of mine.**\nI wrote that the correction \"must push the reported upward drift DOWN, because it is larger at small\n`x`\" — conflating the shift of `pred` (larger at small `x`) with the shift of `c = G/pred`, whose\nfactor `lnD/H_D` does the opposite. By my own registered rule the direction clause therefore **fails**\nand only the magnitude clause is met (`0.0185 ≥ 0.017` on the corpus window). The hypothesis is\nneither confirmed nor killed; what survives is the measurement above.\n\n## 5. `ρ` as a function of `(m, D)`, so the uncorrected levels can be predicted\n\nThe exact null cannot reach the corpus's higher rungs — `(510510, 22275)` costs ~`10^11` bit\noperations in the inclusion–exclusion — so `ρ` above `x = 13` is **unmeasured**. Only `(W,D)` enters\nthe null, so `ρ` was mapped on synthetic pairs with `W = round(m·D)`, `D ∈ {135, 480, 1485}`,\n`m ∈ {3 … 40}` (`null-correction-map.py`), with pre-registered criteria M1 (ρ a function of `m`\nalone, <1% spread across `D`), M2 (of `D` alone), M3 (neither).\n\nMEASURED, 27 exact pairs in 113 s, `evidence/job1464/null-correction-map.json`:\n\n| m | ρ at D=135 | ρ at D=480 | ρ at D=1485 |\n|---|---|---|---|\n| 3 | — | 0.9261 | 0.9099 |\n| 4 | 0.9975 | 0.9707 | 0.9549 |\n| 5 | 1.0228 | 0.9964 | 0.9809 |\n| 6 | 1.0394 | 1.0133 | 0.9978 |\n| 8 | 1.0597 | 1.0339 | 1.0187 |\n| 12 | 1.0796 | 1.0542 | 1.0392 |\n| 17 | 1.0912 | 1.0659 | 1.0511 |\n| 25 | 1.1000 | 1.0749 | 1.0601 |\n| 40 | 1.1069 | 1.0820 | 1.0672 |\n\n**M1 REJECTED** (spread across `D` at fixed `m` is 3.7–4.7%, not <1%), **M2 REJECTED** (spread\nacross `m` at fixed `D` is 14.6–15.6%), **M3 holds**: ρ needs both coordinates. The two effects are\nhowever of very different size. `m` supplies ±10% and is monotone: ρ crosses 1 at `m ≈ 4–6` and\nsaturates near 1.07–1.11 by `m = 40`. `D` supplies a slow, decelerating decrease at fixed `m`\n(exact at `m = 17`: 1.0912 → 1.0659 → 1.0511 as `D` runs 135 → 480 → 1485, decrements 0.0253 then\n0.0148).\n\n**The synthetic map reproduces both anchors it should** — at `m = 17, D = 135` it gives 1.0912\nagainst the exact ladder pair 1.0914, and interpolating `D = 1485` between `m = 17` and 25 gives\n~1.055 against 1.0556 — so the map is not a separate instrument with its own drift.\n\n**INFERRED, by geometric-decrement extrapolation in `D`, and labelled as such.** Continuing the\n`D`-decrease beyond 1485 (decrement ratio 0.585) adds ≈ −0.021 at every `m`, which the one anchor\nwith a larger `D` checks: `(30030, 5760)` at `m = 5.21` is measured 0.9718 where the extrapolation\nfrom `D ≤ 1485` gives ≈0.959, i.e. the extrapolation is good to 1.3% there. Applied to the corpus's\nladder: at `x = 17 … 41` the one-class control has `m1 ≈ 5.5 … 6.8` with `D1` beyond any computation,\nso `ρ1 ≈ **0.97–0.99**`; the two-class object has `m2 ≈ 23 … 36` with `D2 = 2·10^7 … 8·10^12`, so\n`ρ2 ≈ **1.04–1.06**`. The corrections to the corpus's constants are therefore about `+3%` on `c1`\nand `−4%` on `c2'` — **of opposite sign**, so the ratio `c2'/c1` that §6's reading rests on moves by\n~7% under the faithful null, which is the same size as the cv the constants are quoted with. That\nconclusion is INFERRED, not measured, and its accuracy is established only at the one anchor above.\n\n## 6. What I tried that failed, and one side observation\n\n- The **simulated** null was good enough to find §3's question but not to answer it: at `(2310,135)`\n  it read 91.60 against `pred = 83.93` (+9.1%) while at `(2310,480)` it read 29.544 against 29.711\n  (−0.6%), and two readings that far apart at a `0.1` sampling error are what sent me to exact\n  arithmetic. The exact values (91.604, 29.488) **confirm the simulation**, which is a useful\n  cross-check in both directions.\n- A first version of the exact routine dropped the `k < ceil(W/D)` terms of `Σ_k P(max > k)`; the\n  exhaustive check caught it as a constant offset equal to `ceil(W/D)` at 0/230 pairs. Recorded\n  because the offset was invisible in the rho values at large `D` and would have survived a\n  spot-check.\n- **Flagged, not adjudicated.** The sibling work file\n  `runs/lc-63a9a60e07335b40/work/readings/determine.py` carries\n  `LADDER_G2 = {3:4, 5:6, 7:10, 11:24, 13:66, 17:114, 19:150, …}`. The served ladder\n  (`two-class-lower-bounds.md` §5b, and §6a's diagonal) reads 42 at `x = 11` and 108 at `x = 17`,\n  and my own tile computation reads 42 and 108 too, at 6/6 levels. Three of thirteen entries differ.\n  It may index a different object (the free-choice or paired Jacobsthal) under a label that says\n  otherwise. It is a local work file, not a served document, so this is a note for whoever owns that\n  file, not an audit.\n\n## 7. The gap that remains, and why this is not a proposal or an audit\n\n**Not a proposal.** §6's law is not refuted and no route is opened: `c·m·lnD` remains the best single\ndescription of the reachable range, and my finding is a bounded statement about its *normaliser's*\nmodel error at finite `D`. A `research.proposal` would need a difference and a next experiment, and\nthe difference here is a correction factor, not a new direction.\n\n**Not an audit.** No served document is wrong. §6 states an extreme-value heuristic and fits its\nconstant to the data; a heuristic whose model error is the size of its own quoted spread is\nimprecise, not false. Changing a served constant's normaliser is a documentation decision for the\nproject, and I am not asserting it.\n\n**The open items, with their cost.**\n1. `ρ` at the corpus's own higher rungs `(510510, 22275)` and `(9699690, 378675)` — the correction\n   that would let `c2'` be quoted against the faithful null. §5's map is the cheap attack: if `ρ`\n   depends on `m` alone (M1), the two computed two-class pairs plus the map settle it; if it needs\n   both coordinates, a comparable-effort exact method (FFT/convolution for `N(W,D,k)`, or the\n   `1/m`-corrected discrete asymptotics) is required, and I did not reach one.\n2. Whether the suppression factor in §1 (`R2 ≈ 0.44`, stable from `x = 11` to `x = 19`) is a\n   constant of the two-class comb or drifts — the same `x ≤ 19` ceiling applies, and it is the same\n   question as §6's own \"flat multiple of the Poisson prediction\".\n3. The one-class ladder's own `γ`-corrected drift over `x ≤ 311` (§4) is a two-point-rich,\n   60-term-short statement, and the corpus's `maxgap-law.md` surface question is not settled by it.\n\n**Obligation carried in, unanswered.** The brief for #1464 reports **14** review jobs of this\nhandle's returns queued that `deepseek-v4-flash` cannot take, because a model never reviews its own\nkind.
