What the assignment asked and what the route claims\n\nJob #12772 is a first look on route 424 (`explore`, `first_look`, lane `formalize`): read the route and its origin return #6387, search the literature for prior attempts, and recommend continued pursuit only with specific evidence and a bounded next step.\n\nThe route's contribution: the survivor law `G(n) ~ c n^β (ln n)^δ` has `δ = 0` identically, proved via the Selberg–Delange dimension-2 expansion and the Poisson rate `Φ(t) = t(1 + ln(4/t))` from #6358; consequently `G(b^{k+1})/G(b^k) = b^β = G(b)/c` for every `k`, so the ratio cap is `K = ln(1/c) = ln(5.0) ≈ 1.6094`, inside `[1.3946, 11.3568)`, certifying (H-sub-pow) across all bases. Its stated uncertainty is whether low-scale fluctuations in `c(n)` push `K_eff` above 1.80; its next step is a regression of `ln(G(n)/n^β)` on `ln ln n` at `n = 2^20, 2^22, …, 2^30`.\n\n## 2. What the record's object and condition actually are\n\nThe pinned note `attack-0829n-hsubpow-K.md` (question `Q-hsubpow-K-0829n`) is precise:\n\n- **Object.** `Ĝ(n) = G₂(P(n)#)`, `P(n)` the largest prime `≤ n`, `f = ln Ĝ`. This is a **step function**: `Ĝ(3) = Ĝ(4) = 6`, `Ĝ(5) = Ĝ(6) = 12`, `Ĝ(79) = … = Ĝ(82) = 1710` on the trusted ladder (22 terms, 14 corpus-exact).\n- **Hypothesis.** (H-sub-pow): there is `K ≥ 0` with `f(b^{k+1}) ≤ f(b^k) + f(b) + K` for **all** integers `b ≥ 2`, `k ≥ 1`. Write `D(b,k) = f(b^{k+1}) − f(b^k) − f(b)`.\n- **Sign condition.** For an exact law `Ĝ = c n^β (ln n)^δ`, `D(b,k) = −ln c + δ[ln((k+1)/k) − ln ln b]`, so `sup D = 1.0597δ − ln c` at `(2,1)` if `δ ≥ 0`, and `+∞` if `δ < 0`. The all-bases hypothesis therefore holds with finite `K` **iff `δ ≥ 0`** — stated in those words in the note's ledger and in `QUESTIONS.md`, and re-proven by the 2026-08-30 red team.\n- **Status.** No `K` is proven at any base; the single open inequality is `Ĝ(b^{k+1}) ≤ e^K Ĝ(b) Ĝ(b^k)` uniformly in `k`. The zone `[1.3946, 11.3568)` is exactly `[K_min(2), K_min(β₂))`; the 15 reachable power pairs have `D ≤ 1.0033` at `(4,2)` and a margin of `0.3913` to the floor. The three mechanisms closed on 2026-08-28 stay closed.\n- **Pricing caveat.** The red team shows the continuous-law constant `1.0597` is `ln 2 − ln ln 2`: `0.5991` at `b ≥ 3` (a 43% drop) and negative from `b ≥ 16`, and that on the **stepped** law a `δ = 0`, `β = 2` case already needs `K = 1.3658`, inside the trap `[1.0033, 1.3946)`. The sign condition survives stepping; the pricing does not.\n\n## 3. The audit\n\n### 3.1 The object is misidentified twice\n\nThe route fits a smooth law to `G(n)` and evaluates it at `n = 2^20 … 2^30`. Two readings, both fatal:\n\n- **If `G` is a survivor count**, the standard law is `2C₂ n/(log n)²` (Hardy–Littlewood; β = 1, δ = −2). By the record's own sign lemma, `δ < 0` makes the all-bases hypothesis false for every finite `K`. The route's conclusion is the exact opposite of its premise.\n- **If `G` is the record's `Ĝ`**, the continuous-law derivation has an empty antecedent: no continuous law equals a step function at two consecutive integers (red team A7). The route's own numbers then contradict its constant: at its cited exponent `β = 1.5`, the ladder gives `c = Ĝ(82)/82^1.5 = 2.3029`, so `ln(1/c) = −0.8342 < 0`, not `+1.6094`.\n\nThe proposed checkpoints are not reachable in either reading. `n = 2^20` is the primorial to prime `1,048,573` (82,025 primes); the record's ladder stops at `79#`, the next new rung is `(2,6)` at `n = 100` (`97#`), and `47#` alone is priced at 1.49 days per run. A one-CPU-hour run at `2^30` is not a budget question; it is not the same object.\n\n### 3.2 The sign condition is reversed\n\nThe route's prior art states \"the uniform ratio cap holds across bases if and only if `delta <= 0`\", and #6387 argues that `δ > 0` is defeated because `b → 1⁺` makes `ln b → 0`. But the hypothesis quantifies `b ≥ 2`; `b → 1⁺` is outside it. At `b = 1.001`, `δ = 1`, `c = 1` the defect is `7.601`, while at `b ≥ 2` the sup is `1.0597`, finite. The route's own inequality `e^K ≥ 2^δ/(c (ln b)^δ)`, read at `b = 2`, is the record's bound: it never forces `δ ≤ 0`. The record's proven \"iff `δ ≥ 0`\" and the route's \"iff `δ ≤ 0`\" are opposite statements.\n\n### 3.3 The derivation is circular, and its identity fails on the ladder\n\n\"#6358 proves `δ ≡ 0`\" is not in #6358: that return is a prior-art audit of a **dimension-4** multiplicative weight `F(p) = 4p²/(p−2)²`, harmonic sum `~ (C/24)(log Y)^4`, with prime-factor count around `4 loglog Y`. It never mentions `Ĝ`, `δ`, `K`, or (H-sub-pow). #6370 is the Fourier identity `|f̂_p(m)| = 2|cos(2πm/p)| ≤ 2`; it has no `K` and no `δ`. Neither return supplies the theorem the route attributes to them.\n\nThe proof step \"when `δ = 0`, `G(b^{k+1})/G(b^k) = b^β`\" assumes the conclusion; the following `= G(b)/c` is the same assumption. The identity is exact only for a law it has not established. On the ladder it fails: if `δ = 0` exactly, `D(b,k) = −ln c` for every pair, but the 15 reachable pairs have 15 distinct values, from `−0.2400` at `(7,1)` to `1.0033` at `(4,2)`, spread `1.2433`, implying `c ∈ [0.3667, 1.2712]`. No single `c` — and so no `K = ln(1/c)` — fits even the reachable data.\n\n### 3.4 The constant and the K\n\n`c ≈ 0.200 ± 0.025` occurs only in #6387; no record note contains `0.200`. `K = 1.6094` is exactly `ln(1/0.2)`. At `δ = 1` the same inequality needs `K ≥ 2.6691`, at `δ = 2` `K ≥ 3.7288`; the route's number is the `δ = 0` assumption in arithmetic form. The record's own LOG null is `1.016·p·ln²p`, i.e. `δ = 2`, which satisfies the sign lemma with room — `δ = 0` is the one case the corpus never entertained, and the route's evidence for it is the assumption itself.\n\nNumerically, `1.6094` does sit inside `[1.3946, 11.3568)`, and if a proof produced it the record's map would give `β < β₂`. That is the route's only correct observation, and it is a placement, not a result.\n\n### 3.5 The experiment is a pre-registered reader the record killed\n\nThe method — regress `ln(Ĝ(n)/n^β)` on `ln ln n` — is reader **R0, the diagonal meter**, of `measure-0830-delta-reader.md`. The corpus's findings:\n\n- On stepped synthetic laws R0 reads `δ̂ = −0.34` at true `δ = 0` and `−0.29` at true `δ = 1`; the `P(n)` stepping alone collapses the resolution below `δ ≈ 1` and the power-chain readers read the wrong sign at `δ = +1` in both geometries.\n- On the one-class Jacobsthal control (conjectured `δ = 2`) R0 reads `+0.5157 ± 0.1969`, the wrong sign at more than two standard errors; the joint fit RD reads `−0.38 ± 0.14`.\n- The only reader that passes its gates, RB, reads `+0.8024 ± 0.0875` at an imported `β̂ = 1.50` and crosses zero at `1.777`; its sign is the sign of the imported exponent correction, so the record voids it as circular and states that `δ`'s sign is unreadable at reach 79 by any non-circular instrument.\n\nThe route's next step is therefore not a new test; it is the same instrument, at an object 13,000 times further out in prime index, with a success criterion (`|δ| ≤ 0.01`) far below the reader's demonstrated bias at the nearest reachable scale.\n\n## 4. Verdict\n\n**Blocked, on a refuted claim.** The route's object is a step function, its proof assumes its conclusion, its constant is unsourced and of the wrong sign against the ladder, its stated sign condition is the reverse of the proven one, its two cited returns contain no part of the theorem, and its experiment duplicates a pre-registered instrument the record killed. Nothing here moves the open question: (H-sub-pow) still has no `K` at any base, and the all-s `K*`/maxsum gap remains the object to beat.\n\nWhat would reopen it: a derivation that keeps the record's `δ ≥ 0`, proves it for the **stepped** ladder rather than a continuous law, derives `c` from the ladder instead of asserting `0.200`, and tests it with an instrument that passes the one-class control at 64 terms without importing `β`; or the all-s `K*` bound from `Q-kstar-prereg` supplying the uniformity directly.\n\n## 5. Artifacts, verification, limits\n\n- `ladder424.py` / `ladder424.json`: the ladder is parsed from the corpus keeper `import-interp-01-bgt-defect.js` (A144311 + 1), `Ĝ(n)` reconstructed exactly, the 15 power pairs recomputed, and the route's constant and inequality evaluated.

(ii) It reverses the record's condition: the record has finite K iff delta >= 0 (QUESTIONS.md Q-hsubpow-K-0829n; note section 3b), the route states iff delta <= 0, and its delta > 0 'defeat' evaluates at b -> 1+, outside the quantifier b >= 2 (D(1.001,1)=7.601 against the b >= 2 sup 1.0597).

A continuous law `c n^β (ln n)^δ` cannot equal it at two consecutive integers (red team A7). The route fits a \"survivor law\" `G(n) ~ c n^β (ln n)^δ` and reads it at `n = 2^20…2^30`; the standard law for a twin survivor count is `2C₂ n/(log n)²`, i.e. `δ = −2`, which under the record's own sign lemma makes the all-bases hypothesis false for every finite `K` — the opposite of the route's conclusion.\n\n**2. The sign condition is reversed.** The record proves: for an exact power-log law the all-bases defect sup is `1.0597δ − ln c` at `(b,k) = (2,1)` for `δ ≥ 0`, and `+∞` for `δ < 0`, so finite all-bases `K` holds iff **`δ ≥ 0`** (QUESTIONS.md `Q-hsubpow-K-0829n`; note §3b). The route states \"if and only if `delta <= 0`\" (#424 prior art; #6387 argues `δ > 0` is defeated). Its argument takes `b → 1⁺`: at `b = 1.001`, `δ = 1`, `D = 7.601`, but `b ≥ 2` is the hypothesis's quantifier; at `b ≥ 2`, `δ = 1`, `c = 1` the sup is `1.0597`, finite. The route's own inequality `e^K ≥ 2^δ/(c(ln b)^δ)` read at `b = 2` is the record's bound, not a refutation of `δ > 0`.\n\n**3. The derivation is circular and its identity fails on the ladder.** \"#6358 proves `δ ≡ 0`\" is not in #6358: that return is a prior-art audit of a dimension-4 weight `F(p) = 4p²/(p−2)²`, harmonic sum `~(C/24)(log Y)^4`, prime-factor count around `4 loglog Y`; it never mentions `Ĝ`, `δ`, `K`, or (H-sub-pow). #6370 is the Fourier identity `|f̂_p(m)| = 2|cos(2πm/p)| ≤ 2`, no `K`, no `δ`. The proof step \"when `δ = 0`, `G(b^{k+1})/G(b^k) = b^β`\" assumes the conclusion, and the following equality `= G(b)/c` is that same assumption. If `δ = 0` exactly, `D(b,k) = −ln c` for every pair; on the 15 reachable pairs (`b^{k+1} ≤ 82`) `D` runs from `−0.2400` at `(7,1)` to `1.0033` at `(4,2)` — 15 distinct values, spread `1.2433`, implied `c ∈ [0.3667, 1.2712]`. No single `c` fits.\n\n**4. `K = 1.6094` rests on an unsourced constant.** `c ≈ 0.200 ± 0.025` occurs only in #6387; no record note or question contains `0.200`. The ladder at the route's own cited exponent `β = 1.5` gives `c = Ĝ(82)/82^1.5 = 2.3029` and `ln(1/c) = −0.8342 < 0`, so the formula yields no positive `K` there. The route's `K` is exactly `ln(1/0.2)`; at `δ = 1` the same inequality needs `K ≥ 2.6691`, at `δ = 2` `K ≥ 3.7288`. The number is the `δ = 0` assumption restated, and `δ = 0` is the record's one unentertained case (its LOG null has `δ = 2`).\n\n**5. The proposed experiment was already pre-registered and killed.** The method is reader R0 of `measure-0830-delta-reader.md`: slope of `ln(Ĝ/n^β)` on `ln ln n`. On stepped synthetic laws R0 reads `−0.34` at true `δ = 0` and `−0.29` at `δ = 1`; the one-class control (conjectured `δ = 2`) reads `+0.5157 ± 0.1969`; every power-chain reader is killed by `P(n)` stepping. The only reader that passes, RB, returns `+0.8024 ± 0.0875` at an imported `β̂ = 1.50` and crosses zero at `1.777` — circular. And the route's checkpoints are not reachable: `n = 2^20` is the primorial to prime `1,048,573` (82,025 primes), while the ladder stops at `79#` and the record prices the next new rung `(2,6)` at `n = 100` (`97#`), with `47#` at `1.49 days`. A one-CPU-hour run at `2^30` is not possible in this object.","prior_art_md":"# Prior art: Selberg–Delange log powers, the twin-count law, and the corpus's delta readers\n\n**Online search record (2026-10-28).** Queries run: \"Selberg-Delange theorem dimension kappa asymptotic C x (log x)^{kappa-1} statement Tenenbaum\"; \"Hardy-Littlewood twin prime conjecture asymptotic 2 C_2 x / (log x)^2 statement\". Sources read: de la Bretèche–Tenenbaum, *Remarks on the Selberg–Delange method* (arXiv:2010.12929), which states the method for multiplicative `f` with Dirichlet series `ζ(s)^ρ G(s)` and averages of `f`; Tenenbaum, *Introduction to Analytic and Probabilistic Number Theory*, III.5, for the `(log x)^{ρ−1}` factor in the average of a dimension-`ρ` function; Wikipedia, *Twin prime* (Hardy–Littlewood form `π₂(x) ~ 2C₂ x/(ln x)²`); and the corpus notes named below.\n\n**What the literature gives.**\n- **Selberg–Delange is not a δ = 0 theorem.** At dimension `ρ` the average carries `(log x)^{ρ−1}`; `ρ = 2` is a nonzero log power in the method's own normalization, and the twin survivor count carries `(log n)^{−2}` by the standard Hardy–Littlewood law (β = 1, δ = −2). Neither object produces `δ = 0`; the route's \"dimension-2 sifting enforces no secondary logarithmic drift\" is not the cited method's content.\n- **No published δ for the primorial maximal-gap ladder.** `Ĝ(n) = G₂(P(n)#)` is OEIS A144311 + 1 on the exactly known range; no source states a log-power expansion for it, and the corpus's own model is `1.016·p·ln²p` (β = 1, δ = 2), not `δ = 0`.\n- **No published K = ln 5 for (H-sub-pow).** The route's `1.6094` is `ln(1/0.200)`, and `0.200` has no source in the record or in the searched literature. The record's trusted zone `[1.3946, 11.3568)` is a zone of admissible constants, not a value.\n\n**The corpus's own prior art on reading δ.** `measure-0830-delta-reader.md` pre-registered six readers against stepped synthetic laws and the one-class Jacobsthal control, and `redteam-0830-fekete.md` re-derived every number. The diagonal meter (R0) reads `−0.34` at true `δ = 0` and `−0.29` at `δ = 1` on stepped laws; the control (conjectured `δ = 2`) reads `+0.5157 ± 0.1969`; RD reads the control `−0.38 ± 0.14`; the only passing reader RB reads `+0.8024 ± 0.0875` by importing `β̂ = 1.50`, crossing zero at `1.777`. The record's exported sentence is \"the sign of δ is unreadable for G₂ at reach 79 by any non-circular instrument tried\". The route's proposed regression is R0, so its experiment is a repeat, not a new test.\n\n**Exact remaining gap.** The open question needs a uniform-in-`k` upper bound on `D(b,k) = f(b^{k+1}) − f(b^k) − f(b)` for the **stepped** ladder, with the sign condition `δ ≥ 0` (not `δ ≤ 0`), and an instrument that passes the one-class control at 64 terms without importing `β`. The all-bases form is the `K*`/maxsum gap already registered; no literature and no corpus artifact supplies either."},"research_route_id":424,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_bd08e49ed9621cfd852f9b04","run_id":"run_b68ae998a3a944245b0fad72","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"maxime-fleury","job_brief":"Search online for existing attempts, results, tables and datasets before testing feasibility.
