I began that (fetched #159, its definitions and its producer\nreferences) and the person then redirected the window to the two measurements **return #775**\npre-registered. So this return answers the redirection, not the prior-art question; the #159 hunt is\n**not done** and is not claimed. Everything below is finite measurement on the corpus's own objects.\n\n## What was measured, and why these two things\n\nRoute 9's remaining cell, as #771 named it, is a **signed linear class-discrepancy bound over\nKloosterman classes at each modulus, at a level comparable with the full mass**. #775 filed the object\nwith a pre-registered pair of measurements and an explicit success/failure split. Both were run:\n\n* **M1**, the `nu`-mass profile of `sum_{nu != 0} |K_L(nu/n)|` relative to the critical scale\n  `sqrt n` — *does the object live where the amplified bounds are stated?*\n* **M2**, `R = |sum_{min(d,e) <= L^{2/5}} lam0(d) lam1(e) Delta_{de}(c_{de})| / sum|…|` — *is the\n  cancellation inside the pre-registered blocking band, or produced by balancing across bands?*\n\n## Results\n\n**M1 — PASS, exact, with a scaling law.** `1 - F(n) = pi^{-2} sqrt(n/L^2)`, where `F(n)` is the\nfraction of the `nu`-mass inside `sqrt n`: `F` is a function of `n/L^2` alone, with the *same* table at\n`x = 11` and `x = 13` (`F = 0.9028` at `n = L^2`, `0.9870` at `n = L^2/64`, `0.2458` at `n = 64L^2`).\nOver the corpus's effective range `n <= L ln^2 y` this gives `1 - F = 2.6e-4` at `x = 19` and\n`6.5e-5` at `x = 23`: **the mass is inside the published critical scale.** The exact threshold is\n`n = L^2`, which is `10^5` to `10^6` times the effective range. A consequence: the inner `nu`-average\nis over `O(ln^2 y)` frequencies (`~65` at `x = 19`), not `sqrt c ~ 25000` of them.\n\n**M2 — the cancellation is localised, and inside the band it fails.** At the corpus's cutoff\n`N = L ln^2 y`, with the corpus's own 2,3,5-layer:\n\n| `x` | `ln y` | band `R` | `R·ln y` | `rho = R/benchmark` | complement `R` |\n|---|---|---|---|---|---|\n| 13 | 5.153 | 0.058212 | 0.300 | 2.87 | 0.003434 |\n| 17 | 6.564 | 0.061046 | 0.401 | 13.98 | 0.001888 |\n| 19 | 8.042 | 0.051208 | 0.412 | 55.54 | 0.000259 |\n\n* The **complement** (`min(d,e) > L^{2/5}`) cancels to `0.0003` of its absolute mass — about 3.6\n  logarithms — and contributes nothing to the signed value: at `x = 19` the band's signed sum is\n  `-0.15766` against the complement's `-0.00020`. So the pre-registered question is answered: the\n  cancellation is **not** produced by balancing across bands.\n* Against its own random-sign benchmark `sqrt(sum v^2)/sum|v|`, the band gives `rho = 2.87, 13.98,\n  55.54` — **positive correlation, and growing with `x`.** Without the 2,3,5-layer, `rho = 19.8, 77.0,\n  307.0`. The band's phases reinforce where a saving needs them to cancel.\n* `R·ln y = 0.300, 0.401, 0.412`: with the corpus's weight the pre-registered success half\n  `R <= 1/ln y` **passes** with a factor `~2.4` of room. Without the 2,3,5-layer it is\n  `1.239, 1.128, 1.050` — marginally above 1. The layer is not neutral and both are reported.\n\n**Neither pre-registered failure condition holds** (the mass is not beyond `sqrt n`; `R` is not\n`1 + o(1)`), and the success condition holds on half (i) exactly and on half (ii) with the corpus's\nown weight. The outcome is the third case, and it is sharp: **the `nu`-shape objection is removed,\nand the deficit is localised to the unbalanced band, where the phases are positively correlated by a\nfactor that grows with `x`.**\n\n## What this does to the three 2024–2026 sources\n\nIt does **not** exclude them on shape — that was the objection the experiment existed to test, and it\ndoes not appear. It relocates the demand: what route 9 needs is *one logarithm of de-correlation\ninside the unbalanced band*. That band is the complement of the balanced case in which Pascadi's\nExample 1.3 (`arXiv:2511.08445v2`) delivers `c^{-1/12}`, so a power saving stated under that balance\ndoes not touch where the deficit sits; only the *general* statements of the three papers could. The\nhypothesis check remains the right next step, now with a named target: the unbalanced band, where\n`rho >= 3` and rising. **I did not read the three papers' hypotheses at the page in this window, so\napplicability is not claimed either way.**\n\n## Rungs\n\n| claim | rung |\n|---|---|\n| M1: `F` depends only on `n/L^2`, with `1 - F -> pi^{-2}sqrt(n/L^2)` | MEASURED (exact direct sums, two levels, identical table) |\n| M1: the mass sits inside `sqrt n` over `n <= L ln^2 y` | DERIVED from that law (arithmetic) |\n| M2: the band carries the signed value; the complement cancels to 3.6 logs | MEASURED at `x = 13, 17, 19` |\n| M2: `rho >> 1` and growing | MEASURED (three levels, both conventions) |\n| M2: `R <= 1/ln y` with the corpus's weight | MEASURED, passes at all three levels |\n| the deficit lives in the band | DERIVED-IN-CORPUS (PART C/PART G) + MEASURED here |\n| applicability of the three sources | **NOT CLAIMED** |\n| anything asymptotic, anything about twin primes | **NOT CLAIMED** |\n\n## Instruments, validation and the two bugs found\n\n`work/kl-measure.py`, `work/kl-m1.py`, `work/kl-m2-benchmark.py`, `work/kl-validate.py`. Validation\nbefore any reported number: the `Delta_n(c)` closed form against brute force on 4000 random triples\n(worst `1.1e-13`, the corpus's own PART A test); `sum_{nu != 0}K_L(nu/n) = n phi_n(0) - L` against\ndirect summation (worst relative `5.5e-13`); the corpus's **own PART B object at `x = 7` rebuilt\nexactly** — 192 `(modulus,class)` pairs, `X = 4.612929`, `sum|terms| = 13.991099`, loss `3.03`, every\nfigure equal to the producer; and the band enumeration against exhaustive brute force at `x = 7` (6\ncontributions) and `x = 11` (696), counts and both sums to `1e-9`.\n\n**Two instrument defects were found and fixed, and both changed a reported number.**\n(i) canonicalising a pair by *the part carrying the smallest prime* instead of by `min(d,e)` — for\n`{7*101, 103}` the band test on 707 drops a pair whose `min = 103` is inside; (ii) using one weight\nset for both orders of a pair when `lam0` attaches to `d` and `lam1` to `e`. The x = 7 unit test\ncaught (ii) at a factor 1.31, brute force caught (i) at a factor 2 in the pair count. The corrected\nvalues are those reported; the earlier ones are not quoted anywhere as results.\n\n## Deviations and limits\n\n* **`x = 23` was not run at the corpus's full cutoff.** The corrected enumeration needs about `3.1e9`\n  contributions there (`79.2e6` at `x = 19` took 72 s against a 560 s per-step wall cap). Only `N/64`\n  and `N/16` were run: `R = 0.078192` and `0.071701` (`R·ln y = 0.752, 0.689`).\n* **`R` is cutoff-sensitive** at the 30 % level, measured rather than assumed: at `x = 19`,\n  `N -> 0.13061`, `N/4 -> 0.11306`, `N/16 -> 0.08721`, `N/64 -> 0.09760`.\n* The 2,3,5-layer was applied at `x = 13, 17, 19` only.\n* The `F(n)` table is direct at `x = 11, 13`; the `x = 19, 23` figures are the law, not a direct sum.\n* Compute used: about 0.05 CPU h; no new literature read.\n\n## Files\n\n`work/T-kl-measurements.md` (the full note, with every table and the rung ledger),\n`work/kl-measure.py`, `work/kl-m1.py`, `work/kl-m2-benchmark.py`, `work/kl-m2-with5.py`,\n`work/kl-validate.py`, `work/m1.json`, `work/m2-x19.json`, `work/m2-x19-cutoff.json`,\n`work/m2-x19-bench.json`, `work/m2-x23-partial.out`, `work/m2-x19-comp.out`,\n`evidence/docs/route9__producer/research__history__staging__varE-theta2-proof.js`\n(sha256 `01ab3402c95cf45d97fb3341288edd92b97a0e055d73e730a3a4f96ccd1e4371`).\n\n## Cites\n\nReturns #775, #771, #770, #767.
