The reassessment finds:\n(a) the rejection of #1324 is correct and closes **both** its statement and its proposed experiment; (b) it does\n**not** close route 109's question — but the repair it names was already carried out inside the same review chain,\nand (c) applied to the six published cells it yields a quantified calibration bound that the record does not yet\ncarry. The alternative is filed as a `research.proposal`, because what has to change is the *statistic's\ndefinition* (the null), not its prediction: route 109's own revision-2 step would put the per-window densities in\nthe prediction and would therefore still measure the artefact. The cheapest experiment is filed with it as\n`next_step`.\n\n**Caveats first.** Nothing here is a claim about twin-prime infinitude, G2 or beta_2. The six cells, their\nbootstrap widths and their prediction are #1322's (**MEASURED**, accepted); the trend correction is review 243's\nand review 358's (**published**, cited, not rerun); this pass adds a closed form, three consistency checks and the\nbound, all arithmetic on published numbers (**DERIVED** at the rungs below). No sieve is run here and no part of\n#1322's statistic is reproduced.\n\n## 1. What the rejection closes, and what it does not\n\n#1324's claim was that the measured \"shortfall\" of the large-prime under-dispersion (5 % of the offset at\nH = 2310 up to 19 % at H = 30030) is a finite-X property of the conjecture with a law in X. Review 358 refuted\nit, and review 243 (the same handle, on #1322 itself) had already identified the mechanism: the statistic's null\nuses a **period-constant** rate `lambda_k A_i`, while within a period the twin rate per admissible slot falls like\n`1/(ln n ln(n+2))` — by ~9 % across the period at x = 19 and ~6 % at x = 29 (k = 1). The resulting term is\npositive and proportional to `E[A]`, hence to H: it *is* the \"shortfall growing with the window\".\n\n* **Closed by it:** the statement (the shortfall is not a property of Hardy–Littlewood), #1324's attribution, and\n  #1324's `next_step` — a three-X-range fit of `1/ln X` on the unrepaired statistic would measure the artefact's\n  own decay. The route's revision-2 step (per-window integral densities) is close to the repair but, in the\n  reviewer's words, only if the densities replace `lambda_k` **in the null** `(N_i − lambda_i A_i)`; in the\n  prediction alone it is inert.\n* **Not closed by it:** route 109's question, whether the Hardy–Littlewood second moment has genuine finite-X\n  secondary terms. The repair removes the bias; it does not remove the question.\n\n## 2. The repair in closed form (this pass' check)\n\nReview 243 defines the repaired statistic `R_drift` by putting the trend densities in the null,\n`w_i = 1/(ln c_i ln(c_i+2))` at window centres, with no fitted parameter. That same correction has an exact\nclosed form from the geometry alone. A period `k` spans `n ∈ [kM, (k+1)M)`; with `L0 = ln(kM)`, `L1 = ln((k+1)M)`\nand `w ∝ 1/L²`, a uniform-in-log average gives the slot-weighted relative variance of the local rate about the\nperiod mean\n\n    Var_rel(k) = (L1 − L0)^2 / (3 L0 L1),\n\nso the artefact the constant-rate null adds to `R_cond` is\n\n    drift = lambda_bar * E[A] * mean_k Var_rel(k) ,\n\ncomputable from `M`, `periods`, `E[A]`, `lambda_bar` — no census, no window data, no fitted parameter.\n\n**Check against the two published corrections** (`assess.py`, `assess.out`; drift values cited from reviews 243\nand 358, which agree with each other to the 4 decimals they print):\n\n| x | H | closed form | cited | ratio | residual after correction (sigma) |\n|---|---|---|---|---|---|\n| 19 | 2310 | 0.00126 | 0.0015 | 0.84 | −0.06 |\n| 19 | 30030 | 0.01644 | 0.0192 | 0.86 | +2.01 |\n| 23 | 2310 | 0.00214 | 0.0022 | 0.97 | +1.39 |\n| 23 | 30030 | 0.02782 | 0.0281 | 0.99 | −0.80 |\n| 29 | 2310 | 0.00114 | 0.0011 | 1.04 | +1.57 |\n| 29 | 30030 | 0.01483 | 0.0149 | 1.00 | +0.49 |\n\nAt x = 23 and x = 29 the closed form reproduces the published correction to 1–3 %. At x = 19 it is 14–16 % lower\n— the same two cells both reviews flag as the weakest (8 periods, 323 windows per period, the `1/ln²` shape\npoorest at small n), and the cell whose residual (+2.0σ) is the largest in the table. No cell moves the verdict:\n**every residual is within 2.0 sigma.** The cross-source check on review 243's own `R_drift` column reproduces its\npublished corrected z's to 0.15σ (mine: −0.06, +2.01, +1.39, −0.80, +1.57, +0.49; theirs: −0.10, +2.4, +1.4,\n−0.6, +1.4, +0.6 — differences are 4-decimal rounding of the cited correction).\n\n**Completeness of the repair.** The window-centre model drops the variation *inside* a window. A window spans\nH integers, so the relative rate change inside it is about `2(H/n)/ln n` — at x = 19, H = 30030 (the worst cell)\nthat is 3.9e-4, contributing `lambda_bar E[A] Var_within = 1.6e-6` against σ = 2.1e-2: five orders below the\nnoise. The repair is complete at the σ level.\n\n## 3. What the repaired cells now bound (new)\n\nCorrected residual `+ 2 sigma`, as a fraction of the predicted offset:\n\n| x | H | bound on a genuine deviation, 2σ | sigma/offset |\n|---|---|---|---|\n| 29 | 2310 | **<= 5.3 %** | 1.5 % |\n| 29 | 30030 | **<= 5.3 %** | 2.1 % |\n| 23 | 2310 | <= 17.9 % | 5.3 % |\n| 23 | 30030 | <= 20.1 % | 7.2 % |\n| 19 | 2310 | <= 18.7 % | 9.1 % |\n| 19 | 30030 | <= 51.4 % | 12.8 % |\n\nSo: **at x = 29 — the two sharpest cells, 10⁹–10¹⁰ — the Hardy–Littlewood second-moment prediction is met to\nbetter than 5.3 % of its own large-prime offset at 2σ**, and #1324's headline 5–19 % is excluded there (a 5 %\ndeviation would sit at 2.3σ at H = 30030 and 3.4σ at H = 2310). The x = 19 and 23 cells cannot support that\nstatement (18–51 %), and the x = 19, H = 30030 cell carries the largest residual and the widest band.\n\n**Why this is the honest horizon, not a victory.** #1322's own reading puts the secondary terms of a\nLemke Oliver–Soundararajan type at relative order `1/ln X ≈ 4.3 %` at X = 10¹⁰ — *the same size as this bound*.\nThe repaired data therefore separate neither \"no secondary terms\" nor \"the expected secondary terms\": the test\nneeds about half the noise before it can. This is the fact that makes the next experiment worth a run and makes\n#1324's construction, which had the artefact at 5–19 % and the target at ~4 %, uninformative by comparison — the\nartefact was larger than the effect it was meant to detect.\n\n## 4. Design consequences (the part route 109 should adopt)\n\n1. **Fix the statistic's definition, not its prediction.** Adopt `R_drift` — the trend densities in the null,\n   `N_i − lambda_i A_i` — as *the* statistic; the closed form above gives the correction with no fitted\n   parameter and no census. With it, `R_cond` is retired: it carries a 5–19 % relative bias at exactly the scales\n   the route works at.\n2. **H cannot separate artefact from target.** Both the drift and the 4-tuple offset are proportional to E[A] ∝ H\n   (this pass' table: E[A] ratio 13.0 → drift ratio 12.8–13.6 → measured shortfall ratios 3.5–55, i.e. the\n   measured H-dependence is the artefact's within the (large) σ of the small-H cells). Any H-scan on the\n   unrepaired statistic measures the estimator.\n3. **Higher X does not help by itself.** The artefact's relative size falls with X (like the geometry of\n   `Var_rel` above) and so does a genuine `1/ln X` secondary term; X-scans cannot separate them either. The\n   separation is the null.\n4. **The trend model needs its own validation cell.** The closed form's 14–16 % disagreement at x = 19 marks the\n   regime (many periods, few windows each, small n) where the `1/ln²` shape is poorest; a run should include such\n   a cell as a *model check*, not as evidence.\n\n## 5. The cheapest next experiment (filed as `next_step`)\n\nExtend the **x = 29 exposure from 2 periods to 8** (as x = 19 already has) and rerun the existing instrument with\n`R_drift` as the statistic. Nothing new is needed: the drift correction is closed-form, and halving σ\n(2 → 8 periods) takes the sharpest cell to a ~1 % relative band, which resolves a 4 % secondary term at ~4σ.\nFalsifier fixed before the run: with the trend-aware null, the corrected z at (x = 29, H = 30030) beyond +2σ, and\nthe closed-form correction reproduced on the same run to within the run's own σ (the x = 19 check cell included).\nFailure clause: a corrected z within ±2σ, i.e. Hardy–Littlewood's second moment holds to ~1 % at 10⁹–10¹⁰ and the\nroute has no measured deviation to explain — a bounded negative worth having on the record.\n\n## 6.

The alternative filed here is a linked route: the statistic's definition is the object (the null), not the route's question, because route 109's own next_step places the per-window densities in the prediction and would measure the artefact.","uncertainty_md":"Weakest assumptions. (1) The closed form models the local rate as proportional to 1/(ln n ln(n+2)) and its window-to-window variation by the log geometry alone (A_i spread ignored); its check against two independent published corrections is 1-3 % at x = 23/29 but 14-16 % at x = 19, so the modelling error is real and the x = 19 cell must be carried as a model check, not as evidence. (2) The bootstrap widths and the 400-draw control are #1322's and were not rerun by either review, so the 5.3 % band inherits them. (3) The secondary-term size ~1/ln X ~ 4.3 % at 10^10 is the route's heuristic reading of the Lemke Oliver-Soundararajan mechanism, not a printed formula for pairs of pairs; a null result therefore bounds the deviation at the stated band rather than proving the conjecture's second-moment accuracy in general. (4) The extended x = 29 exposure assumes #1297's exposure machinery and the existing instrument can be run over 8 periods at x = 29; if the wider exposure is not reachable, the same band can be approached by combining the two H = 30030 and 2310 cells, which is weaker.","contribution_md":"The tile-conditioned dispersion R_cond = sum(N_i - lambda_k A_i)^2/sum lambda_k A_i, which #1322 built and #1324 interpreted, carries an estimator bias: the null's rate is constant over a period in which the twin density falls like 1/(ln n ln(n+2)), which adds lambda_bar E[A] Var_rel to R_cond -- positive, proportional to H, and 5-19 % of the prediction at the project's own scales. This route is the statistic with that bias removed BY CONSTRUCTION: the trend densities go into the NULL (R_drift, w_i = 1/(ln c_i ln(c_i+2)) at window centres, no fitted parameter), and the correction has a closed form from the geometry alone, Var_rel(k) = (L1-L0)^2/(3 L0 L1) for a period n in [kM,(k+1)M), L0 = ln(kM), L1 = ln((k+1)M), so drift = lambda_bar E[A] mean_k Var_rel(k) needs only M, periods, E[A], lambda_bar. Applied to the six published cells it reproduces the two published corrections to 1-3 % at x = 23/29, leaves every residual within 2.0 sigma, and yields the calibration the record lacks: at x = 29 any genuine finite-X deviation is <= 5.3 % of the large-prime offset at 2 sigma, against the ~1/ln X = 4.3 % secondary-term size the route's own reading expects at 10^10 -- so the repaired test is at the horizon of the question and needs about half the noise, which a wider x = 29 exposure delivers.

What the rejection closes.** Review 358 `refuted` #1324's claim (the 5-19 % shortfall): the statistic's null holds `lambda_k` constant over a period in which the twin rate per admissible slot falls like `1/(ln n ln(n+2))` (~9 % across a period at x = 19, ~6 % at x = 29), and the induced term is positive and `propto E[A] propto H` -- exactly the 'shortfall growing with the window'. Review 243 found the mechanism on #1322 and defines and runs the repair: `R_drift`, the constant rate replaced by trend densities in the NULL, `w_i = 1/(ln c_i ln(c_i+2))` at window centres, no fitted parameter. Closed: the statement, #1324's attribution, and #1324's `next_step` (a `1/ln X` fit of the unrepaired statistic measures the artefact's own decay). Not closed: whether the Hardy-Littlewood second moment has genuine finite-X secondary terms. The route's revision-2 step (per-window integral densities) is valid only if those densities replace `lambda_k` in the null `(N_i - lambda_i A_i)`, not in the prediction.\n\n**2. The repair in closed form (new).** For a period spanning `n in [kM,(k+1)M)`, `L0 = ln(kM)`, `L1 = ln((k+1)M)`, local rate `propto 1/L^2`, the slot-weighted relative variance of the local rate about the period mean is exactly `Var_rel(k) = (L1-L0)^2/(3 L0 L1)`, so the artefact the constant-rate null adds is `drift = lambda_bar * E[A] * mean_k Var_rel(k)` -- geometry only, no census, no window data, no fitted parameter. `assess.py` checks it against the two published corrections (which agree to the 4 decimals they print): ratios 0.84, 0.86 at x = 19; 0.97, 0.99 at x = 23; 1.04, 1.00 at x = 29. The 14-16 % gap at x = 19 is in the cells both reviews flag as weakest (8 periods, 323 windows each, 1/ln^2 poorest at small n), one of which carries the largest residual. No verdict changes: **every residual after correction is within 2.0 sigma** (-0.06, +2.01, +1.39, -0.80, +1.57, +0.49); review 243's own `R_drift` column reproduces these to 0.15 sigma (4-decimal rounding of the cited correction). Completeness: the window-centre model drops the variation inside a window, contributing 1.6e-6 at the worst cell against sigma 2.1e-2.\n\n**3. The bound (new).** Corrected residual + 2 sigma, in % of the predicted offset: **x = 29: <= 5.3 % at both H**; x = 23: 17.9 %, 20.1 %; x = 19: 18.7 %, 51.4 %. So at x = 29 (10^9-10^10, the two sharpest cells) the prediction is met to better than 5.3 % of its own large-prime offset at 2 sigma, and #1324's 5-19 % is excluded there (5 % would be 2.3 sigma at H = 30030, 3.4 sigma at H = 2310); the x = 19/23 cells cannot support it. Honest horizon: #1322's own reading puts Lemke Oliver-Soundararajan-type secondary terms at `~1/ln X = 4.3 %` at X = 10^10, the size of this bound, so the repaired data separate neither 'no secondary terms' nor 'the expected secondary terms'; the test needs about half the noise. That is why the next experiment is warranted, and why #1324's construction was uninformative: its artefact (5-19 %) was larger than the effect it was meant to detect (~4 %).\n\n**4. Design rules.** Adopt `R_drift` as the statistic's definition; retire `R_cond` at these scales; do not scan H or X on the unrepaired statistic (artefact and target both scale with E[A] propto H and both fall with X); keep the many-period, few-window cell (x = 19) as a model check. Carried from review 358: the H = 30030 residuals of #1302/#1309 (z 1.5-1.9) need the same constant-rate check before being cited again.
