What was asked, and the one-line answer\n\nFind something new: a route, connection, counterexample or testable hypothesis, with its nearest prior\nwork, exact difference and cheapest refuting experiment. The open question of record used here is TODO\nitem **1d**, `Q-hsubpow-K-0829n` (**OPEN**, one of only two OPEN entries in the served questions list):\ncan (H-sub-pow) be proven with an explicit `K` inside the trusted legal zone `[1.3946, 11.3568)`?\n\nIts own note proves the decisive structural fact — the all-bases hypothesis holds with a finite `K` **iff\nthe second-order exponent `δ` of the law `Ĝ ~ c n^β (ln n)^δ` satisfies `δ ≥ 0`** — and reads `δ` off the\nreachable ladder with **one** estimator, the `k = 1` diagonal, which fails its control (the one-class\nJacobshal ladder, conjectured `δ = 2 + o(1)`, reads `+0.5157 ± 0.1969`: wrong sign, > 2 s.e.). The corpus\ntherefore calls the `G₂` reading void and the sign of `δ` unknown two-sided.\n\nWhat this return adds, measured: **the second slice of the same identity fails the same control, and by\nmore.** The rung estimator (the whole family `D(b,k)`, `k = 1…7`, at a fixed base) is exact to `1e−12` on\nsynthetic laws of the stated class, and on the control it reads `−0.3341 ± 0.2364` at reach 82 and\n`−0.3637 ± 0.1725` at reach 312 — **9.9 and 13.7 s.e. from the conjectured `2`**, and it misses by *more*\nthan the diagonal does at the same reach (`2.3341` versus `1.4702`). The failure is therefore not a\nproperty of the `k = 1` slice: the ladder at reach ≤ 312 is not in the regime where the sign lemma's\nidentity applies, for either slice. The proposal below changes the ingredient accordingly: decide the\nsecond-order **sign by bounds, not by a fit**.\n\n## 1. The object, and the identity both estimators come from\n\n`Ĝ(n) = G₂(P(n)#)`, `P(n)` the largest prime `≤ n`, `f = ln Ĝ`, and\n\n> **(H-sub-pow)** `f(b^{k+1}) ≤ f(b^k) + f(b) + K` for all `b ≥ 2`, `k ≥ 1`, with defect\n> `D(b,k) = f(b^{k+1}) − f(b^k) − f(b)`.\n\nBoth estimators are slices of the corpus's own sign lemma (`attack-0829n-hsubpow-K.md` §3b,\n**[PROVEN]**): for an exact law `Ĝ(n) = c n^β (ln n)^δ`,\n`D(b,k) = −ln c + δ[ln((k+1)/k) − ln ln b]`. Hence\n\n- the **diagonal** (their estimator): `D(b,1)` against `ln ln b`, slope `−δ`;\n- the **rung estimator** (this return): `D(b,k)` against `x = ln((k+1)/k)` at a fixed base, slope `δ`,\n  intercept `−ln c − δ ln ln b`, plus the `c`- and `b`-free ratio form\n  `δ = (D(b,k₂) − D(b,k₁)) / ln(k₁(k₂+1)/(k₂(k₁+1)))`.\n\n`check_cd.py` reproduces the corpus's own numbers before using the instrument: trusted sup `1.0033` at\n`(b,k) = (4,2)`, custody sup `0.9694` at `(2,4)`, control sup `0.6931` at `(9,1)` at `G₂`'s reach and\n`0.9478` at `(10,1)` at its own, the three diagonal slopes `+0.0961 ± 0.4137`, `+0.5298 ± 0.3018`,\n`+0.5157 ± 0.1969`, the pair counts `15 / 9 / 15 / 29`, and the `10.3535`-nat margin — all to the last\ndigit the corpus prints. The ladders are parsed from the served bytes (`A144311 + 1`, 22 terms to\n`p = 79`; the control `A048670`, 64 terms to `p = 311`; the custody 14), never retyped, and the two\nladders need **different prime lists** (a shared one silently truncates the control's own reach — the\nfirst bug this checker found).\n\n## 2. The pre-registered test, and its outcome\n\nThe control ladder carries two reaches, so it can say which estimator improves with more data. Written\nbefore the run: *the instrument that should read `δ` is the one whose control reading moves toward the\nconjectured `2 + o(1)` as the reach grows.* Outcome:\n\n| estimator | reach 82 | reach 312 | distance from 2 |\n|---|---|---|---|\n| diagonal (`k = 1`, bases 2..9 / 2..17) | `+0.5298 ± 0.3018` | `+0.5157 ± 0.1969` | `1.47` → `1.48` (does not move) |\n| **rung** (base 2, `k = 1..5` / `1..7`) | `−0.3341 ± 0.2364` | `−0.3637 ± 0.1725` | `2.33` → **`2.36`** |\n\nThe rung instrument fails its control, `9.9` and `13.7` s.e. away, and the failure is not slice-specific.\nOn the object of record the rung reading is `−0.2149 ± 1.0343` at base 2 (5 rungs; base 3 gives 3 rungs,\nbase 4 only 2, too few to fit) — consistent with zero and with the control's own reading, so it does\n**not** establish the sign of `δ` on the reachable ladder, and neither does the diagonal.\n\n**Scoped negative, recorded:** within the ladders on record — `Ĝ` trusted to `n = 82`, the control to\n`n = 312`, custody to 46 — no slice of the sign lemma's identity reads `δ` for `Ĝ`; the estimator that\nwas calibrated on synthetic laws of the stated class reads the *control's own* conjectured `δ = 2` as\n`−0.36`. The ladder is not in the exact-law regime, and **the repair \"use a different slice\" is closed at\nthis reach**. This is a failure to detect, at two reaches and two slices, not a refutation of any law.\n\n## 3. The proposal (filed as `research.proposal`)\n\n**The sign of the second-order term, decided by bounds instead of by a ladder fit.**\n\n- **Object.** The sign of `δ` in the corpus's own law class for `Ĝ`; equivalently whether the all-bases\n  (H-sub-pow) is a proof gap or a truth gap, and the one inequality the legal zone needs — the note's T7\n  is a *necessary* condition `K ≥ 1.0597δ − ln c`, so an upper bound on `δ` is exactly what the zone\n  consumes.\n- **The step that would have to hold.** The corpus already carries the two sides: a published floor\n  (`Ĝ ≥ g ≫ x ln x lnlnln x/lnln x`, the FGKMT-type input, `two-class-lower-bounds.md` §3, **[CITED]**)\n  and the upper inputs on the ladder (the trusted terms to `Ĝ(82) = 1710`, the period bound, the maxsum\n  certificate). The route is to write the *bracket* they impose on the second-order term at the reachable\n  ladder and ask whether it is one-signed — no fit, no extrapolation, and no use of the identity that has\n  now failed twice.\n- **Nearest prior work and the exact difference.** `attack-hsub-01.md` (the reduction), `hsubpow-explicit-K.md`\n  (the zone and the three closed mechanisms), `attack-0829n-hsubpow-K.md` (this identity, the diagonal and\n  its control failure), the counterexample of return **#1947** (regular variation alone does not suffice),\n  and the two placements of **#156**/**#61** (both proved, both conditional on Dusart T5.2). All of these\n  *fit or bound the constant `K` under an assumed law*; none decides the sign of the second-order term from\n  the two-sided bound inputs, and the corpus itself states \"nothing bounds it above at any exponent\".\n- **Cheapest experiment that could refute it** (also the filed `next_step`): a source lookup of the\n  floor's explicit constants plus arithmetic on the 22-term column — compute `ln(Ĝ(n)/g(n))` and its slope\n  on `ln ln n` over the reachable ladder and test whether the bracket excludes `δ < 0`. If the floor's\n  constants are not effective at `n ≤ 82`, or the bracket contains both signs, the route is refuted at\n  this scope and the negative is recorded; cost ≈ 0 CPU-h, budget 1.0 h.\n\n## 4. Scope, and what is not claimed\n\nEvery number here is either a corpus value reproduced from served bytes or a standard-library arithmetic\nresult on those values; no count, `G₂` value, censor or enumeration is produced. `δ` is a property of an\nassumed law class (`c n^β (ln n)^δ`), and the identifiability statements are inside that class only. The\ncontrol's conjectured `δ = 2 + o(1)` is Maier–Pomerance's `J(x) = x(log x)^{2+o(1)}` (**[CITED]**,\nexternal; the two readings are of the *ladder*, not a test of that conjecture). The two `−0.33`/`−0.36`\nreadings are **failure to detect**, not evidence of `δ < 0` for any object, and the `G₂` reading is void\nat eight bases by the corpus's own standard. Nothing here moves `K`, the zone, or any twin-prime bound.\n\n## 5. Unresolved obligations\n\nNo `request_review`: a route proposal is recorded without claim review, and the measurement inside it is\na scoped negative with its falsifier stated. The proposal's own weakest assumption (is the published\nfloor effective at `n ≤ 82`?) is named in `uncertainty_md` and is the first thing the next experiment\nresolves. One line for the person: no action needed; the route's first check is cheap and its failure\nmode is explicit.\n","patch":null,"cpu_hours":0,"hashes":{"04a8ef821fb38597d8c13dfa95c2cfe6028c1863ae3c68aa3ad7f3e02d604657":"register_cd.json","04ca5803cfd1a647f4f1b74f2de28994d98cb6c2b628470a17bfa58a2bfca3e5":"next_step.json","19946280d879bb1cd7e78ea47e6f4e10c91172c9701b38eead5c6de5c7bf893e":"api.py","20ad0a1961c8b8e2e46ad49ba754cb5bd2afd93de899e0d0e5977caa724ec6fd":"f-import-interp-01-bgt-defect.js","2393ea47c24a22000b0708647a9c93eca4ee835b8427ef87e452ce25b0e7dd3c":"questions.json","625f4ee9c237d44fc32a1e155f8c8b8daa75a7597b97d272ec26284a7d425d75":"report_cd.md","74cd6a9cbc0203b92cd9fe07ce69ae4facc2cca0beb9e6a206ce294c9462fd23":"build_transcript_cd.py","761b7e4250a7d938592710dba0ba9af94ddae7affb2876a1e21c3c759925a096":"evidence_cd.md","874ffd8a1ca10588308ee7fe84714bd10d7d4cda07a1341bf41544d77e2489b0":"check_cd.control.out","972f02bec24e7f45ad1f73910fe01dc9c04eb34e7df6827806d9729cef2e11d3":"transcript.cd.final.jsonl","999d2c5fa3ab24769ed77b6fb79ae4f92207a1d9d0b153839bc6bff673d5e729":"f-exact-g2-ladder.js","9c8f18de0e5c0000da7bfd939062a1d15ffc5871cede0db14aeb2a066bd3e703":"check_cd.py","bbabf49678d8ef4fb65c0fe3b66397baa2a926f2927b66b94715e809f1d311d0":"f-attack-0829n-hsubpow-K.js","bfdf0096d03d9a16b752e426171f82e25dc38fd61a89bf7de5e09c163d703df4":"doc-research_history_staging_attack-0829n-hsubpow-K.md","c3f277df5d64f3b09cc5fe3674f2b2a09b06b661b28dd49f64bb220e8aa1c0c8":"doc-research_history_staging_hsubpow-explicit-K.md","cc8398e0f8c409af13968450c42cb1c81ec15b1449d28f56d6477135cf12d239":"proposal.json","dbf0b5ba81fe66db7964e756e52ca4e82121dce5454816642d49313619e371ff":"f-exponent-control.js","de3354dd6254d5bf1814b8618874a9040ac515ac17f1e3d0030041abc2c1431f":"doc-research_QUESTIONS.md","e14a2607fc7551458d7152005f4d5552f6bf0d1f07912101847a6b2f013da2dd":"check_cd.out","f672d5a6efdf570cd698ca426bcd8feab623f960c82f669bb50105afeaef89ec":"recipe_cd.md","fc4d1a59a7553fa8f234fc0ae68aa39fa3e883941c744020787624d90bfdda65":"doc-TODO.md"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-07T22:32:22.135Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[1947,156,61],"messages":[]},"tokens":{"log":"custom","input":0,"models":{"deepseek-v4-flash-fast":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":["deepseek-v4-flash-fast"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe — job #5290 (new-route discovery: which instrument should read delta?)\n\nReproduce in ≤ 10 min, **0 CPU-h**, stdlib only.

(2) 'Maier Pomerance Jacobsthal function primorial p# asymptotic p (ln p)^2 + o(1) two-sided bounds' - the control's conjectured order is external and on record: Maier-Pomerance's J(x) = x(log x)^{2+o(1)} (Ford, Annals 183 (2016) p.4 p.1311 ff; Ford's 2018 colloquium slides state the conjecture verbatim), and Hagedorn's computational upper bound arXiv:1208.5342; also the project's own moire write-up. This confirms the control's conjectured delta = 2 + o(1) as a CITED external anchor, nothing more. (3) 'second order term logarithmic power law exponent sign detectable from finite ladder numerical fit slow convergence' - generic power-law fitting material; nothing on deciding the sign of a second-order exponent from a finite ladder, which is precisely the uncovered step. Internal prior work inspected at source: attack-hsub-01.md (the reduction and the prime-only/base-lattice question), hsubpow-explicit-K.md (the zone, the three closed mechanisms, the trusted-zone correction), attack-0829n-hsubpow-K.md (the identity, the diagonal, its control failure, the lifting identity, the sign lemma), return #1947's counterexample (regular variation with a nonnegative slowly varying correction does not suffice), and the theta and p placements of #156/#61 (both proved, both conditional on Dusart T5.2). None of them decides the sign of the second-order term from the two-sided bound inputs; the note itself says 'nothing bounds it above at any exponent'. Access gaps: the floor's explicit constants (two-class-lower-bounds.md section 3) were not fetched in this pass; the exponent-control.md section 5 measured columns were read only through the owner note's citation.

If the constants are asymptotic-only and the ceiling inputs are loose, the bracket contains both signs, the sign stays undecided by this route too, and the honest outcome is a second scoped negative: the sign of delta for Ghat is not decidable from the inputs on record by any means tried so far. A secondary assumption is that the stated law class c n^beta (ln n)^delta is the right class for Ghat at all; the owner note's own measurement that the ladder is not in the exact-law regime at reach 17 is evidence against trusting the class at 82, and the proposal therefore avoids using the class for a read and uses it only to state what a bound would mean.","contribution_md":"The all-bases (H-sub-pow) f(b^(k+1)) <= f(b^k) + f(b) + K (f = ln G2(P(n)#)) is the single remaining gap of the bounded-defect route, and the owner note's PROVEN sign lemma says it holds with a finite K if and only if the second-order exponent delta of Ghat ~ c n^beta (ln n)^delta is >= 0; the legal zone [1.3946, 11.3568) then consumes K >= 1.0597 delta - ln c (its T7 is a necessary condition), so an upper bound on delta is exactly the quantity the zone needs.

Success of the proposed route would decide the sign at a stated scope from inputs the corpus already carries - a published floor and the upper inputs - turning 'the ladder cannot see it' into either a proof gap with an explicit K obligation or a truth gap that says no finite K exists at any base.

Its own **[PROVEN]** sign lemma\nfixes the stakes: the all-bases hypothesis holds with finite `K` **iff `δ ≥ 0`** for a law\n`Ĝ ~ c n^β (ln n)^δ`, and for an exact law `D(b,k) = f(b^{k+1}) − f(b^k) − f(b) = −ln c + δ[ln((k+1)/k) − ln ln b]`.\n\n**Instrument and calibration.** `check_cd.py` (stdlib only, imports/executes no producer code) uses that\nidentity twice: the corpus's `k = 1` diagonal against `ln ln b` (slope `−δ`), and the whole rung family\nat a fixed base, `D(b,k)` against `ln((k+1)/k)` (slope `δ`, intercept `−ln c − δ ln ln b`), plus the `c`- and\n`b`-free ratio form. Synthetic laws at `δ = 2, 0, −1, −2` and bases `2, 3, 7` return `δ` to `1e−12` by both\nforms and the intercept matches the lemma, so the estimator is exact **for the stated law class** and any\nfailure below is a property of the ladder, not of the estimator.\n\n**Reproduction, from the served bytes.** Ladders parsed, never retyped:\n`A144311 + 1` (22 terms to prime 79; custody 14 identical) and the control `A048670` (64 terms to 311),\nwhich need **different** prime lists. Reproduced to the digit: trusted sup `1.0033` at `(4,2)`, custody\n`0.9694` at `(2,4)`, control `0.6931` at `(9,1)` at `G₂`'s reach and `0.9478` at `(10,1)` at its own;\npair counts `15 / 9 / 15 / 29`; diagonal slopes `+0.0961 ± 0.4137`, `+0.5298 ± 0.3018`,\n`+0.5157 ± 0.1969`; margin `10.3535` nats.\n\n**Pre-registered test and outcome.** Written before the run: the instrument that should read `δ` is the\none whose control reading moves toward `2 + o(1)` as reach grows. Rung readings on the control:\n`−0.3341 ± 0.2364` at reach 82 (5 rungs) and `−0.3637 ± 0.1725` at reach 312 (7 rungs) — **9.9 and 13.7\ns.e. from 2**, and missing by more than the diagonal at the same reach (`|rung − 2| = 2.3341` vs\n`|diagonal − 2| = 1.4702`).

Scoped negative: within the ladders on record (82\ntrusted, 312 control, 46 custody) **no slice of the identity reads `δ`** — a failure to detect twice over,\nnot a refutation of any law, and an extension of the corpus's own diagonal finding.\n\n**The route proposed.** Decide the sign by **bounds**: the bracket the published floor (`Ĝ ≥ g`,\nFGKMT-type, `two-class-lower-bounds.md` §3) and the upper inputs (trusted ladder to `Ĝ(82) = 1710`, period\nbound, maxsum certificate) impose on the second-order term at the reachable ladder — the zone consumes\nexactly `K ≥ 1.0597δ − ln c`.
