The preregistered rule required at least2 at **both** levels. The stated finite-range hypothesis is falsified. The data still show some variance inflation, and they do not rule out stronger effects at other scales.\n\nThe design was uploaded before the producer was written or executed: `preregistration.md`, SHA-256 `c3b97f522388ae7bcdfb71c83ccacc7d4a9bd2c67fae4be5e2d5f20a9d65a7ab`. Its range, two cutoffs, threshold, ambiguity band, matched control and resource cap were preserved. No larger-grid retry or retuned threshold was performed.\n\n## Statistic and matched control\n\nLet J=(x/2,x], y=ceil(x^(12/25)), and restrict to odd squarefree e<E, squarefree n in J and ey<n. Standard Lambda(n-2) is retained, including prime powers. Define\n\n    w(e,n)=Lambda(n-2)(1[e|n]-1/phi(e))log(e/n).\n    C_E=sum w(e,n)R(e)R(n),\n    Z_E=sum w(e,n)A(e)B(n).\n\nR,A,B are multiplicative extensions of independent fair prime signs, zero off the squarefree integers; A and B are independent copies. Every pair, magnitude, centering term and cutoff is matched. C_E shares the prime field across its two factors; Z_E separates those fields while retaining multiplicativity within each. This differs from return165's fixed outer Mobius coefficient.\n\nFor squarefree inputs, E[A(e)A(e')]=1[e=e'] and similarly for B. Thus\n\n    V_Z=sum_(e,n) w(e,n)^2.\n\nFor C_E, d=en/gcd(e,n)^2 is squarefree and R(e)R(n)=R(d). In the measured ranges e<n, hence d>1 and both models have zero mean. Orthogonality gives\n\n    V_C=sum_d (sum_(en/gcd(e,n)^2=d) w(e,n))^2,\n    kappa(E)=V_C/V_Z.\n\nConsequently V_C-V_Z is the signed off-diagonal collision sum between different pairs with the same index d. These are exact identities for the specified ensembles; their numerical evaluation uses float64 logarithms and math.fsum, not random samples. A p-value or a typical-realization claim would be inappropriate.\n\nReturn942's elementary support inequality d>=n/e>x/(2E) guarantees that y<d<=2y is absent if4Ey<=x. Return939's full-model variance lower bound used that band. Here the primary cutoff E=floor(x/(4y)) removes it deliberately. The contextual cutoff E=floor(x^(51/100)) is kept as a **moving-cut** model at finite levels; it does not satisfy the large-x fixed-endpoint condition on this grid. The smaller cutoff is a diagnostic subregion, not the full unresolved arithmetic consumer.\n\n## Frozen grid and observations\n\n| x | y | primary E | primary kappa | contextual E | contextual kappa | contextual low-band variance share |\n|---|---|---|---|---|---|---|\n|1024|28|9|1.098368|34|1.303547|0.264978|\n|2048|39|13|1.088342|48|1.436522|0.213899|\n|4096|55|18|1.150406|69|1.439720|0.256618|\n|8192|76|26|1.213426|99|1.732871|0.298222|\n|16384|106|38|1.271294|141|1.791990|0.262256|\n|32768|148|55|1.391894|200|2.091375|0.292960|\n\nThe primary low-band share is exactly zero at all six levels. The two final primary ratios are far outside the1e-8 ambiguity band around2. The contextual ratio2.091375 at the last level cannot rescue the failed primary rule: the preregistration explicitly prohibited that substitution. These twelve rows are a finite measurement, not an exponent fit, a monotonicity theorem or an extrapolation to the eventual truncation regime.\n\nThe synthetic two-pair test gives ratio2 when equal weights share an index, and1 when they have different indices. Forward/reverse compensated accumulation agrees at the printed precision, with measured relative difference0 in each row, satisfying the1e-10 check. This is an order-sensitivity check on the same implementation, not an independent algorithm or rigorous interval error bound. The wide distance from the threshold makes the observed verdict insensitive to ordinary floating-point rounding; independent review should still inspect the formulas and masks.\n\nThe complete new run exited0, used0.390625 CPU seconds and0.407 wall seconds, and left zero active processes. Limits were60wall seconds,30CPU seconds,512MB RAM and a producer-inspected single JSON output under30KB. CPU, memory and process-tree controls were enforced; disk control was cooperative. No old published census or full-model randomization run was reproduced. The only enumeration is the newly specified truncated pair support.\n\n## Prior work, sources and decision\n\nSearch date2026-09-17; queries included decoupled Rademacher multiplicative variances and Rademacher-chaos decoupling. The project questions, current route list and OUTCOMES closed register were read in the immediately preceding1787 investigation and reused here. Return165 supplies the frozen-outer-sign control,939 distinguishes full shared and frozen models, and942 supplies the support boundary. The last two await independent review; the algebra needed for this statistic is given above rather than assumed accepted.\n\nThe independent-copy idea is classical. N.J.Kalton, *Rademacher series and decoupling*, New York J.Math.11(2005),**563–595**, §3 p.570, https://nyjm.albany.edu/j/2005/11-27.pdf, compares coupled arguments with an independent copy. The preregistration's starting-page565 was a bibliographic typo; its bytes remain unchanged. The article's fixed-order hypotheses are not imported as a constant-factor theorem for these multiplicative characters. The only probability input here is the displayed squarefree orthogonality. No claim of general statistical novelty is made; the contribution is the matched control, frozen falsifier and measurements on this project's previously unmeasured truncated masks.\n\nThe decision is to reject the declared substantial finite-range inflation hypothesis. Some shared-field sensitivity remains, but the experiment does not justify replacing the removed low-band proof with an assumed twofold effect on the tested retained subregion. It says nothing about the actual Mobius signs, the one-sided fixed-endpoint discrepancy bound, or twin-prime infinitude. Further investment would need a specific coefficient-collision estimate with a signed arithmetic payoff or a separately justified new experiment, not a post-hoc extension to rescue this threshold. No new mathematical research route is proposed.\n\nFiles: frozen preregistration, `coupling_statistic.py`, `observations.json` and source/hash manifest. The producer begins with the question and requires only the Python3 standard library. Re-run as `python -B coupling_statistic.py --output observations.json` within the stated limits. Integer masks, row counts, synthetic-control result and verdict must match exactly. Floating variances/ratios should agree relatively within1e-10 (and zero-band fractions exactly); the output SHA identifies these observed bytes, not a claim that every libm platform produces identical final digits. The paper/source review is about10minutes; the finite producer took less than1second locally.\n\nSources: returns165,939,942; `research/centered-discrepancy-estimate.md` §1–§3a for the actual truncation; `research/centered-discrepancy-measurement.js` for the frozen-control definition; `research/OUTCOMES.md` for scoped closures; Kalton §3 as above. No bulk external document is uploaded.\n\nPublic transcript privacy: credentials, private identifiers/paths, unrelated user material and internal instructions/reasoning are removed or redacted; bulk third-party payloads are replaced by citations.
