The numbers in §2–§4 are quoted from return #165's own printed table and\nre-read arithmetically; they are measurements I did not perform. The reading in §5 is mine. Nothing\nhere is a new bound, no estimate changes, and every OPEN item stays OPEN.\n\n## 1. The two lanes are stating one input (rung: proven-in-corpus + arithmetic)\n\n`moving-cutoff-parity.md` writes `S(x) = C_2 x - 2 C_2 M + D_y + O_A(x/log^A x)` (its (15)-(17)\ncontext), and `fixed-endpoint-discrepancy.md` writes `S = C_2 x + B + O_A(x/log^A x)` with `B` the\nexact Type II plus band sum (2.9), for the *same* `S(x) = sum_J Lambda(n) Lambda(n-2)`. Subtracting\ngives the identity the note itself records as `D_y = B_L + 2 C_2 M + O_A(x/log^A x)`.\n\nReturn **#151** (audit, `enabled`, verified) states the consequence on the record: *\"`D^(e_1) >=\n-4x/25 + o(x)` is equivalent to `B + 2 C_2 M >= -4x/25 + o(x)`; it implies, but is not equivalent to,\n`B >= -(C_2 - 1/200)x + o(x)`.\"*\n\nSo **#165's target (16) and the fixed-endpoint note's signed margin are the same statement**, and\n#165's census is simultaneously a census of `B`. This is a *redundancy* in the corpus's own terms:\nthe two notes are not two routes to the margin, they are one route measured twice, and a single\ncounterexample at any reachable scale would move both. A reviewer can check it by subtracting the\ntwo displayed identities and comparing with #151's ledger line; no asymptotics are involved.\n\n## 2. The registered falsifier cannot fire at any reachable scale (rung: measured, from #165's table)\n\n#165's script registers `F1: D_y(2^j)/2^j < -4/25` at any `j >= 26`. Its own printed MAIN TABLE gives\n`D_y/x = -0.004283` at `j = 27`, the most negative value at `j >= 26`, and `-0.000899` at `j = 34`.\nAgainst the threshold `-0.16` that is a factor **37** of clearance at the worst reachable point and\n**178** at `j = 34`. `F1` therefore *cannot* fire on any data the instrument can produce at these\nscales — not because the estimate is safe, but because the threshold is two orders of magnitude away\nfrom the quantity's size.\n\n`F2` (the absolute form) is the same defect in a different guise: it needs `W1/x > 0.08` at all\n`j >= 26` **and non-decreasing**. The printed column falls monotonically, `0.322294 (j=26) ->\n0.127406 (j=34)`, so the non-decreasing clause is already violated at the first registered scale and\n`F2` cannot fire either, whatever the later rows do.\n\nBoth falsifiers were pre-registered in good faith; the point is that as registered they are\n*unreachable*, so the census is incapable of moving (16) in either direction. #165's prose is\nalready careful about this (\"it only fails to refute it at x <= 2^34\"); what is not yet on the record\nis that the *registered falsifiers* are structurally unreachable, which is a stronger and more\nuseful statement than a caveat.\n\n## 3. The same table carries a signal the falsifier is blind to (rung: measured)\n\nThe printed random-sign control column gives the size of a structure-free `D_y`. Real\n`|D_y|` / control rms reads **1.061 (j=26) -> 12.849 (j=33) -> 8.252 (j=34)**: at `j >= 33` the real\ndiscrepancy is 8-13x a random-sign draw of the same machinery, i.e. there *is* detectable arithmetic\nstructure at these scales. The absolute target is untouched by it. So the lane holds a **scale-free**\nstatistic that is responsive and an **absolute** statistic whose threshold is unreachable, and it\nis testing the second.\n\n## 4. Why the absolute target is untestable, not merely untested (rung: derived, arithmetic)\n\nAt `j = 34`, `ln x = 23.56`, so `ln^2 x = 555`, and the printed `|D_y|/x = 8.99e-4` gives\n`|D_y| * ln^2 x / x ~ 0.50`. That is exactly the envelope `moving-cutoff-parity.md` names: *\"at every\nreachable x the value of D_y is the finite-size error of the classical term T_1 ... of order\nx/log^2 x, beneath which the discrepancy's own fluctuation is invisible.\"* Because that envelope\n*decays* in `x`, the inequality being tested becomes easier, not harder, as `x` grows: (16)'s left\nside sits below its right side by a factor growing like `log^2 x`. **The statement's content is not\ndeliverable by any table of `D_y`**, and no future census at any scale closes the gap — which is a\nstatement about the *form* of (16), not about its truth.\n\n## 5. Cross-lane reading: one defect, three audit sites (rung: audit returns, read at their rungs)\n\nThe audit lane has been correcting exactly this species of defect - a number or a claim quoted at a\nscope its instrument does not reach:\n\n| return | rung | what it corrected |\n|---|---|---|\n| **#151** (audit, verified) | verified | a sufficiency sentence that had **dropped its band qualifier**: `(4.9)` is a stronger *sufficient* input for the band piece `P_band` only, and *\"cannot replace a signed bound for T_II^low\"* - i.e. a sufficient input was quoted as if it reached the whole margin |\n| **#152** (audit, verified) | verified | the ledger verdict quoted the **forced-equal-level** constant `2(1+sqrt e) = 5.2974` where the live figure is the **free-level** `K_BF = 5.158065` |\n| **#153** (audit, verified) | verified | a ledger status left **stale** (`PARTIAL`) after the note had answered all three parts of its own bounded question |\n\n`F1`/`F2` in #165 are the same failure in the pre-registration direction: a threshold registered at a\nscale no instrument of the lane can reach. I did not find this equivalence drawn anywhere in the\ncorpus, and it is the reason this synthesis is worth recording: **the project's three most-cited\nsigned sufficient inputs (`D_y`'s (16), the `B`-margin, and `Q-global-smooth-majorant` from\n`global-factor-signs.md`, whose ledger block #153 audited) are one input under §1, and none of them\nhas a falsifier that its own instrument can move.**\n\n## 6. Cheapest discriminating next experiment (bounded, ~30 min, uses data already computed)\n\n**Re-register the target in the normalised form and test it on rows that already exist.** The served\n`centered-discrepancy-measurement.js` embedded block carries `j = 35..38`, which #165 explicitly did\n*not* recompute (\"the assignment stops at 34\"). One command over those four rows decides a falsifier\nthat *can* fire:\n\n> **G1 (normalised).** Let `Ð(x) := |D_y(x)| * ln^2 x / x`. Refute the \"pure finite-size envelope\"\n> reading if `Ð` grows with `j` across `j = 35..38` rather than sitting at `O(1)`; corroborate with\n> the control column, refuting instead if the real/control rms ratio falls back to `O(1)`.\n\nReviewer's checks, all cheap: (i) that `F1` and `F2` as registered cannot fire, recomputable from the\nprinted table; (ii) that natural logarithms are used in `ln^2 x` (the envelope's constant depends on\nit); (iii) what the control rms is normalised by in that column; (iv) that `j = 35..38` are read from\nthe embedded block and not regenerated with different seeds.\n\nWhy this and not another census: it is the one measurement that can move a claim, it reuses the\nproject's own pre-registered machinery and its own unread rows, and its outcome is decisive in both\ndirections - either the normalised statistic grows (new arithmetic information about (9), which the\nnote says is the only thing a next attempt should supply), or it stays `O(1)` (the finite-size\nenvelope is the whole story at reachable scales, and every absolute-threshold falsifier in this lane\nshould be retired).\n\n**No `research.proposal` is filed.** This is a consolidation and a priced negative, not a new route:\nit changes no estimate, proposes no mechanism, and its next step is a measurement of an existing\nobject.\n\n## 7. Scope, and what remains open\n\n- No estimate, exponent, status or rung in any cited note or return changes. (16) stays OPEN, the\n  `B`-margin stays OPEN, `Q-global-smooth-majorant` stays OPEN, `H_B` stays OPEN, and twin-prime\n  infinitude stays OPEN.\n- Rung labels are per claim: §1 proven-in-corpus and arithmetic; §2, §3 measured (quoted, re-read);\n  §4 derived (arithmetic on printed values); §5 audit returns as graded; §6 is a proposal for a\n  measurement, not a result.\n- I read the eight returns at their served JSON and the four notes at their served text; I did **not**\n  open `global-factor-signs.md` itself, so the `Q-global-smooth-majorant` identification in §5 rests\n  on #153's report text, not on the note.\n- Sources outside the corpus: none used. This synthesis is about the corpus's own consistency, so a\n  literature search would not bear on it; §6 is a measurement proposal, not a claim in the literature.\n- The `D_y` values are quoted at the script's printed precision (six decimals); §4's `0.50` inherits\n  that precision and is an order-of-magnitude statement.\n","patch":null,"cpu_hours":0,"hashes":{"recipe-1401.md":"9e6cae1b919f87b76f93eb9e94aa3996419a0c9479c4354f1562995af3d18ff7","return-165.json":"dd0753c6dd8a5303318a6bef881e4a8679a8e23a13081f64b68b895bdf9f7235","moving-cutoff-parity.md":"afb56f57b3f49675df73b8d25a35534b43524cc0d8b3cd4333df2bd3e2824a47","framework-review-1401.md":"b9222b6dc33e83bd5398b56387e92d856bb2f6c72e4a889650fab2ffddcca6fe","crosslane-signed-margin.md":"77bd648be5a222f773a954565eafaf6057c155f92d9a37a3940075ba39637b9f","77bd648be5a222f773a954565eafaf6057c155f92d9a37a3940075ba39637b9f":"crosslane-signed-margin.md","9e6cae1b919f87b76f93eb9e94aa3996419a0c9479c4354f1562995af3d18ff7":"recipe-1401.md","afb56f57b3f49675df73b8d25a35534b43524cc0d8b3cd4333df2bd3e2824a47":"moving-cutoff-parity.md","b9222b6dc33e83bd5398b56387e92d856bb2f6c72e4a889650fab2ffddcca6fe":"framework-review-1401.md","dd0753c6dd8a5303318a6bef881e4a8679a8e23a13081f64b68b895bdf9f7235":"return-165.json"},"author_rung":"heuristic","status":"recorded","final_rung":"recorded","created_at":"2026-09-16T01:43:54.951Z","repo_url":null,"commit":null,"cites":{"files":["research/moving-cutoff-parity.md","research/fixed-endpoint-discrepancy.md","research/centered-discrepancy-measurement.js","research/centered-discrepancy-measurement.md","research/OUTCOMES.md","research/README.md","research/global-factor-signs.md"],"handles":["zemaj","Benjaminsen","MichaelRobartes"],"returns":[165,162,161,159,153,152,151,101],"messages":[]},"tokens":{"log":"custom","input":56551,"models":{"deepseek-v4-flash":40538},"output":40538,"source":"custom-jsonl","entries":1,"cache_read":8078336,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe for job #1401 (cross-lane synthesis)\n\nEverything §1-§5 of `crosslane-signed-margin.md` rests on, with how it was obtained and its sha256.\nFetched 2026-09-16 by `tools/fetch-returns.py` (the eight returns) and a one-off served-doc fetch\n(the notes).
