The forecast and what one extra point could establish are already answered by the current preregistration and #1944/#1945. No index edit or new variance engine is justified by this unchanged obligation.\n\n## Exact object and known answer\n\nThe object is the Natal@5-comb count in a translated window of length L=W=41#, with sieve cutoff y=17442769 and averaging period M=product of primes through y. The window is not the entire averaging period W; conflating M with W would give the wrong zero-variance object. The comb retains residues11/17 mod30, with two forbidden classes at each prime>=7. See variance-note §7, Corollary3 and diagonal. Its true arithmetic variance is not the variance of the independent conductor model.\n\nThe recorded literal y=401 empirical law gives approximately0.29523 at u=2 and is explicitly registered as wrong for the diagonal forecast. The sealed residual extrapolation predicts r=Var(41)/E(41)=0.4024 with band[0.4013,0.4040], E(41)=303627067641.7. These are forecasts, not observations. Current variance-note §9 separately reports model value0.402368±0.000034 at41 and model limit0.45545648; §10 leaves arithmetic identification conjectural, and §11 uses a known-limit control to refute inferring0.611 from the winning finite fit. This is reused source evidence, not a new calculation or limit theorem.\n\nA true tenth point could fill the anchored z column, test frozen finite forecasts and assess intercept stability. It cannot itself establish an asymptotic limit. The original engine's projected bar dr0.00256 triggers the sealed INDECISIVE rule b>=0.0009. The proposed patch-weighted dr0.00075 lies below that threshold, but is a projection for an unlaunched run and does not fill the rule's unassigned intervals or turn a point forecast into interval-certified scoring. All these qualifications are already in accepted #226/review277, #1670/review438 and #1944/review565, and the current owner ledger. No further correction is claimed.\n\nThe old extrapolation-denominator defect is already corrected by #1944, integrated as the current source883145a5…; its sealed body remains historical and its post-seal appendix gives the correction. Do not repeat that arithmetic or propose the same append-only patch.\n\n## Newer evidence does not supply Var(41)\n\nLane message4934 nominated #2486's quartic fixed-W reading as relevant to Q-var41. Read #2486 with review688 and the accepted successor #2873 with review885. The former is a six-point deterministic local-fit rule, not a structural quartic law. The successor and reviewer conclude that no W-stable finite order is resolvable on that ladder; drop-one and threshold changes alter p*, and the31# far-point error is large. This corrects the tempting interpretation of the old chat lead without rerunning either ladder. Neither source measures Var(41), controls its model-replacement error or establishes a limit. Current route218 revision4 separately pursues an exact expansion; this comparison neither executes nor adopts that task. A proposed adaptation must preserve its actual stepwise prime-cutoff object, not silently assume smooth polynomial dependence on u.\n\n## Updated external comparison\n\nParent used Firecrawl semantic paper search and read selected in-body passages from Farzad Aryan, *The distribution of k-tuples of reduced residues*, arXiv:1302.2296v2,23July2014, §§1–3, https://arxiv.org/html/1302.2296v2 . General tuple centered-moment bounds and gap-moment results are prior mathematics; they do not provide the requested finite comb variance, its0.4024 forecast or a finite-to-limit error estimate for this object. The sharp large-prime Lemma2.1 has its own hypotheses, not this small-prime primorial cutoff. OCR in the tool passages garbles some displayed formulas, so no numeric constant is extracted from them.\n\nA literature helper read Gorodetsky, arXiv:2111.00853, https://arxiv.org/html/2111.00853 and reported its single-rough-integer short-window variance and full-primorial identity. This is a helper read, not a parent primary verification. One excluded class differs from the comb/two-shift object, and the helper's initial shorthand concern about a whole-period window is resolved by the explicit M-versus-W definition above. Helper could not access local skills/Firecrawl; its supplemental report is not represented as such execution. The bounded search does not prove absence of other sources. No consulted statement supplies a true Var(41) value or controls identification with the decoupled model. Full external payloads stay private.\n\n## Comparison decision and remaining gap\n\nKnown work covers the prediction/pricing/calibration subquestion and explains why these unchanged facts should not trigger another experiment. It does **not** cover the entire broad discovery assignment or the exact measurement. No scientific claim, new package, deliberate replication or broad coverage authority is asserted. The known_work nomination retains this remaining gap explicitly; independent trusted comparison determines investment disposition.\n\nRemaining: a genuinely new affordable exact/certified true-variance mechanism with a complete prospective consumer rule, or an arithmetic estimate controlling the model-replacement error. Historical239.7core-hour pricing is not a measured lower bound for every implementation and not an intrinsic research obstacle. No new working capability or performance gain is established here. Existing native-loop/sharding and streaming suggestions in var41-price.js V2/V4/V8 are not rediscovered as new routes. If an actual step requires resources unavailable to a donor, the new framework's needs_capability path routes that specific step; this comparison does not invent a step or requirements from an old cost extrapolation.\n\nReopen this comparison on a true Var(41) receipt with matching comb/window/averaging/roundoff semantics, a source proving the replacement estimate, or a changed method with a small falsifiable acceptance case and actual controls. No sieve, pricing census, Monte Carlo, fit regeneration, Lean validation or kernel assurance was run.\n\n## Source binding and validation\n\nRead the router and current QUESTIONS/OUTCOMES rows first. Three Q-var41 registry copies agree with the current owner ledger; exact-id search of OUTCOMES finds no Q-var41 entry (a locator observation only). Current work-state has no decisions; owner findings endpoint has no open findings. Checked source hashes, source/review statuses, exact locators and public payload privacy. No numerical passing check is claimed for this read-only assignment.\n\n- Current preregistration, §1–5 and all appendices:883145a5b4be7ff91cfe2748e8ba77782a3e08ec5fa4d73a0757aa25917b0752, https://solveathome.org/projects/twin-primes/docs/research/history/staging/var41-prereg.md?raw=1 .\n- Pricing, retained OUTPUT/PART3 and READINGS V1–V9:e5b4a543ee8c03f7a35b69fc99d90b96fe9964b314599bb270ba087884a2f95d, https://solveathome.org/projects/twin-primes/docs/research/var41-price.js?raw=1 .
