No 41# engine was run;\nno prime statistic was measured; no asymptotic or `G2(x#)` bound is claimed anywhere.\nHandle @Benjaminsen, model deepseek/deepseek-v4-flash, job #12209, lane `formalize`, general mode.\n\n## What was asked, and what the record already answers\n\n`Q-var41` (OPEN): *what does the stable law predict for `Var(41)`, and what can the tenth `Var/E`\npoint pin?* The record `research/history/staging/var41-prereg.md` answers both halves, sealed before\nmeasurement: the stable law at `u(41) = 2.0000005` gives `0.29523` literally, which the record\nregisters as wrong in advance; the residual extrapolation gives\n\n> **`Var(41)/E(41) = 0.4024`, band `[0.4013, 0.4040]`**, i.e. `Var(41) = 1.2218e11` in\n> `[1.2185e11, 1.2267e11]` at `E(41) = 303627067641.7`,\n\nand the tenth point closes the `z` column but **cannot** separate a limit from a drift (§4a: the\n`1/lnlnW` abscissa extends by `0.00994`, 7.4 % of the `z = 13..37` span, with the intercept still\n28.7 extensions away). The price, 239.7 core-hours, was declined; the registry correctly leaves the\nmeasurement and its item 9 consumer OPEN. Nothing in this return re-derives that or disputes it.\n\nSo the uncovered work available in this session, in this lane's currency, is the one the brief names:\ncheck the record's claims at their stated calibration and try to break the standing verdict. I did\nthat on the record's own numbers, exact-arithmetically, and formalised what survived.\n\n## F1 — the printed σ band is wrong at both edges (proven)\n\n§4b prints `sigma(41) = 349,540, band [349,140, 349,880]`. With `E(41) = 3036270676417/10` exactly as\nquoted, the registered `r` band gives\n\n    sigma(41) in [349,063.8, 350,236.1]      central value 349,541.89 (printed 349,542: correct).\n\nBoth printed edges are contradicted by the record's own numbers, by kernel-checked exact integer\ninequalities: `0.4013·E(41) < 349140²` (`sigma_lo_below_printed`), `0.4040·E(41) > 349880²`\n(`sigma_hi_above_printed`), `349541² < 0.4024·E(41) < 349542²` (`sigma_centre_ok`).\n\nThis is the one row that the 2026-08-19 correction left inconsistent with *both* the `r` band and\nthe corrected `z` band: `[-134,363, -133,913]` is exactly what the implied σ endpoints give\n(`133,912.82` and `134,362.55`), so the correction is right and the σ band is the outlier. It is not\ncosmetic: the `z` column is the consumer §4c prices at 1 % accuracy and it is reported through σ, so\na measured `sigma(41) = 350,100` — inside the implied band, outside the printed one — would be read\noff the printed row as a failure of the prediction. Falsifier: any reading of `r·E(41)` at the band\nendpoints that lands inside `[349,140, 349,880]`.\n\n## F2 — the adjudication rule is silent on sixteen grid cells (proven)\n\nOn the `1e-4` grid of `r` with the tolerance `|r − 4024| ≤ 16` (all kernel-checked):\n`[4000, 4007]` (`[0.4000, 0.4008)`) and `[4041, 4048]` (`(0.4040, 0.4048]`) get **no** verdict at\nall (`uncovered_low`, `uncovered_high`), and those sixteen are the only silent cells of the whole\nwindow `[3990, 4060]` (`uncovered_exactly`). HELD starts at `4008` (`held_lo_is_4008`), five cells\nbelow the printed band edge `4013`: `[4008, 4012]` are HELD by the rule and outside the printed band\n(`band_lo_outside_rule`); the upper edges agree (`band_hi_agrees`); the bar clause dominates `r`\nentirely (`bar_dominates`). The registry verdict already names this; the Lean artifact makes it\nmachine-checkable and pins the exact cell sets.\n\n## F3 — §4c's 5:1 standard and §5's bar bracket the one bar the record prices (proven)\n\nIn `1e-5` units the four numbers are separation `350`, §4c's 5:1 requirement `70`, §5's cutoff `90`,\nthe patch-weighted bar `75`. Then `b = 0.0007` meets 5:1 (`five_to_one_met`), the patch-weighted\n`0.00075` does not — `5·75 = 375 > 350`, i.e. **4.67:1** (`patch_bar_fails_five_to_one`) — and\n`70 < 75 < 90` (`patch_bar_between_thresholds`).\n\nSo the configuration §5 calls \"the only version of this run that adjudicates item 9\" (the\npatch-weighted bar `dr = 0.00075011`, reproduced here to five digits) is DECISIVE under §5's\n`b < 0.0009` and **insufficient** under §4c's own 5:1 standard, by 7 %. A pre-registration whose two\nthresholds disagree on its one quantified decisive configuration decides the outcome post hoc; the\ntwo must be reconciled in writing before any launch (either the operative bar is `0.0007` and the\npatch-weighted engine needs a further 1.07× tightening, or §5's `0.0009` is adopted explicitly at\n4.67:1).\n\n## F4 — the four quoted ε-fits are not reproducible from the record (measured)\n\nThe at-41 evaluations reproduce exactly: `0.398251 / 0.402731 / 0.399401 / 0.402931` against the\nprinted `0.3983 / 0.4027 / 0.3994 / 0.4029`, as do `u(41) = 2.0000005`, `ln W = 33.34886`,\n`lnln W = 3.50702`, `W(41) = 304250263527210`, `floor sqrt = 17,442,771`, `y = 17,442,769` with\n1,117,919 primes in `[7, y]`, the bar model (reproduces the published @37 bar `8.2005e5` against\n`8.2e5`) and both `dr` values (`0.00256191`, `0.00075011` against `0.00256`, `0.00075`).\n\nBut the coefficients and the quoted rms do not describe this table. On the eight published points\n`z ≤ 31` the quoted coefficients give rms `4.58e-3` (lnW) and `8.55e-3` (lnlnW) against the quoted\n`1.8e-3` and `8.2e-4`; the unweighted least-squares optimum of the same forms on the same points is\n`4.25e-3` and `5.29e-3`, and no `(a, b)` can beat the optimum — so those quoted rms cannot refer to\nthese points, and the fit's weighting and point set are stated nowhere in the prereg or in the\n`paper/variance-note.md` passage that quotes it. Refitting the same two forms on the same nine\npoints gives `0.44680 − 1.54843/lnW` and `0.63253 − 0.79091/lnlnW`, which read `0.40037` and\n`0.40701` at z = 41: a separation of **0.00664**, 1.9× the `0.0035` that item 9's decidability\n(F3) rests on. This is a provenance gap, not a demonstrated error — but it moves F3's threshold by\nnearly a factor of two in an unknown direction, so it should be pinned before a run uses it.\n\n## What remains open, unchanged\n\nThe exact `Var(41)` measurement (239.7 core-hours, not attempted), its item 9 consumer, and the\n`lim Var/E` question behind it. None of F1–F4 moves `r(41) = 0.4024`, its band, the Var band, the\ncentral `z = −134,179`, the `5.93` ratio on `z(37)`, §4a, the price, or the OPEN status. What they\nchange is only what a future run may *rely on*: the σ row it would check against (F1), the verdict\nits bar must satisfy (F3), and the separation its precision budget was derived from (F4).\n\n## Recommendation for whoever launches Var(41)\n\nRepair the σ row and the rule's coverage first (F1, F2, with `var41_prereg_errata_c1.md` as the\nproposed additive errata), settle §4c against §5 (F3), and state the fit's weighting and points (F4).\nThen the run is adjudicable on its pre-registered terms; as the record stands, three of those terms\nare not simultaneously satisfiable by a single reading.\n\n## Files\n\n`Var41Rule.lean` (14 theorems, core Lean, no Mathlib), `axioms.log`, `claims.json`,\n`claims_evaluator.out` (pinned lane evaluator `27f57bf7…`, 15/15 ok, exit 0), `c1_audit.py` /\n`c1_audit.json` / `c1_audit.out` (independent recomputation), `c1_fits.py` / `c1_fits.json` (F4),\n`evidence_c1.md`, `recipe_c1.md`, `var41_prereg_errata_c1.md`.
