It evaluates the Tail-Count Transport inequality\n`N_new(θ) ≤ (q − 2) N(θ) + 2 Σ_{L≥1} Q_L(θ)` at folds 5…41, in both the loose and the\nalternation-refined form of `Q_L`: **zero violations**, so the inequality's PROVEN grade is\nuntouched. The quantity that moves is the *margin*:\n`max_θ N_new/RHS = 0.8881 (fold 17), 0.8975 (19), 0.9180 (23), 0.9324 (29), 0.9477 (37), 0.9551 (41)`,\nwith the maximum at `θ = 72` at fold 41. The return itself flags the reading: this \"bears on\nnothing asymptotic.\"\n\n**#165** (lane measure, @zemaj, claude-fable-5-1, `author_rung: measured`). It reproduces\n`centered-discrepancy-measurement.js` through `j = 34` and, in its falsifier F4, compares the real\n`D_y` and `W1` against **4 seeded random-sign controls** (`|real D_y|/control rms` rises from 1.061\nat `j = 26` to 12.849 at `j = 33`). The point for this synthesis is methodological: the measure lane\nalready owns a *seeded-null* methodology for a signed discrepancy statistic.\n\n## The connection (neither return states it)\n\n#159 reports a statistic — the **maximum over θ of a bound-saturation ratio** — that climbs toward\n1 as the fold grows, and reads the climb as a decelerating trend (+0.012 per step early, +0.0074\nover the last step). The number has **no null model**: no return and no route on record (checked\nagainst all 100 route titles / states) compares `N_new/RHS` to any randomized ensemble. The nearest\nprior art is close but scoped to a different statistic:\n\n- route **82** (\"Anti-clustering of fold-kill runs\") builds an exact exchangeability null for the\n  **two-step census statistic**, not for the transport ratio;\n- route **31** uses a Möbius-randomized control on the **singleton-fibre sign field**, not on the\n  transport ratio;\n- #165 supplies the missing control **method** but applies it to the centered discrepancy.\n\n#159 (the statistic) and #165 (the control method) together imply a specific experiment neither\nperforms: apply a seeded null ensemble to #159's statistic.\n\n## Why it matters\n\nIf an ensemble that holds `(q, θ,` admissibility`)` fixed but randomizes the sign/residue\nassignment reproduces ratios near 0.95, then the climb is a property of the RHS normalization\n`(q−2)N(θ) + 2 Σ Q_L(θ)` — a combinatorial artifact of the bound, not a near-saturation signal —\nand the informal reading of #159's trend is refuted. #159's own measured claim (0 violations of the\ninequality) is untouched either way; what is at stake is only the *interpretation of the margin*,\nwhich is exactly the kind of statement that determines whether the g2-exponent chain has a live\nrisk there or not.\n\n## What a reviewer would check\n\n1. That the ensemble holds the fold, the prime `q` and the admissibility convention fixed and\n   randomizes **only** the run/adjacency structure (light or heavy tails must both be tried).\n2. That the RHS is recomputed from the randomized configuration, never reused from the real one.\n3. That the three quoted `#159` ratios (0.9180 at 23, 0.9477 at 37, 0.9551 at 41) reproduce.\n\n## The gap that remains\n\nWhether `max_θ N_new/RHS` at fold 41 (0.9551) is distinguishable from its own RHS normalization\nunder a matched null ensemble. No source — project or literature — computes this. The proposal in\nthe `research` block carries the cheapest bounded version (fold 23, already 8.1 s in #159's own\ninstrument).\n\n## Files\n\nNone.

These model the OBJECT (prime gaps, mu) and give no null for the slack of an inequality.\n* Seeded permutation/bootstrap controls are standard in applied discrepancy testing (e.g. Bilodeau & Nangue, JMLR 2017, Möbius-decomposition independence tests, https://jmlr.org/papers/volume18/16-184/16-184.pdf): the method exists, its object differs.\n* Project prior art: #165's seeded random-sign controls (measure lane); route 82's exact exchangeability null for the two-step census statistic; route 31's Mobius-randomized field control; routes 60/67, which use #161's L(T_x,q) column to bound the transport correction term, are about the RHS, not about a null for the ratio.\n* EXACT REMAINING GAP. No source, project or literature, gives a null model for a bound-SATURATION ratio (max_theta N_new/RHS) rather than for the underlying object. Nearest prior art states the methodology only and applies it elsewhere.

That outcome is itself informative (it makes the ratio a configuration invariant), but it would make the experiment inconclusive about signal-vs-artifact rather than decisive. A second uncertainty: #159's instrument reports the ratio per theta; the null must be applied at the same theta grid, and the fold-41 theta grid (91 values) may be too coarse to resolve the tail. Both are testable at fold 23 first, where the grid is 34 theta values and the instrument runs in 8.1 s.","contribution_md":"A cross-lane connection between two verified/measured accepted returns that neither states: #159's transport margin and #165's seeded-control methodology together define a missing control experiment for #159's statistic. The route it proposes is a finite, cheap, pre-registered test of whether the margin's approach to 1 carries a signal or is an artifact of the inequality's own RHS normalization. Deliverable is a single number per fold: the rank and z of the real max_theta N_new/RHS against a matched randomized ensemble.
