The step under check, and that it is the served one\n\nRoute 200 is `active`, revision **4**, `last_return_id \"2493\"`; its held `next_step` was set by\n**#2493** and is the step this job was told to compare. The assigned brief quotes it byte-for-byte:\n`method` **765** chars, sha256 `d409dc7d2a57abcb94d053576ba292a40a2d9d2c73f18486a93b5577d3f49a01`\n(verified against `GET /research-routes/200`); `question`, `success`, `failure` and\n`budget_hours 0.5` / `compute {ram_gb 2, disk_gb 1, cpu_hours 0.5}` all identical.\n\nThe step is a **no-new-computation re-parameterisation** of #2493's own saved artifact: for\n`k = 1..8` compute the exact integer `N_k(q) = q*P_q(L0(q)-k) = sum_j max(0, d_j - L0 + k)` and the\nexact null counterpart `q*P_null(L0-k)`, fit `s(q,k) = log(N_k / (q*P_null(L0-k))) / log(R_A(q))`\nat each rung with a published `R_A` anchor (7#..19#), and report the sign, range and `q`-drift of\n`s(q,k)` at each `k`. `R_A` at 23# is the one new number the step would add.\n\n## 2. Comparison: no return on record answers it\n\nThe brief names the candidates to compare against (latest on the route first, then linked routes):\n**#2874, #2868, #2845, #2572, #2570, #2516**; route 200's own record is #2393, #2397, #2403, #2418,\n#2493.\n\nThe decisive search is negative and machine-checked. Across all 11 fetched returns, the step's own\nobjects — `s(q,k)`, `N_k(q)`, `L0(q)-k`, `run_length_distribution` — occur **only** inside a field\nthat merely *quotes* a step: route 200's held `next_step`, #2493's own `next_step` (the step's\nauthor), its `next_step.json` file, and the route record's event quoting that same step. They occur\n**zero** times in any `report_md`, `evidence_md`, `prior_art_md`, `research_evidence`, `finding` or\nother served file. In particular `s(q,k)` and `N_k` occur **0** times in every candidate's report\ntext. So no return has fitted the exponent, and none has published `N_k` for `k >= 2`.\n\nWhat each named candidate actually settles:\n\n| return | route | status | relation to this step |\n|---|---|---|---|\n| **#2493** | 200 | recorded (`progress`) | the step's author. Publishes the input artifact (`empty_window_tail.json`: exact gap multiset per rung 7#..23#), the `L0` ladder `30,42,66,108,150,204`, the empty crossing cell `q*P_q(L*) = 0` at all six rungs, the `R_A(q/2)` anchors **7#..19# only** (`R_A_q_half` is `null` at 23#), and the `k = 1` tail count `q*P_q(L0-1) = 2,4,12,20,20,4`. It fits no exponent and computes no `N_k` for `k >= 2`. |\n| **#2403** | 200 | recorded (`proposed`) | the route's origin: three `R0` ratio cells and the five `R_A(q/2)` anchors used as the step's instrument validation. No tail below `L0`, no exponent. |\n| **#2418** | 200 | recorded (`promising`) | the earlier step check that established the premise the held step builds on (`R0(L*) = 0`, so `p(c)` is undefined at the crossing scale) and re-aimed the route at the **count** tail. No fit. |\n| **#2516** | 198 | **accepted / measured** | route 198's own pursuit, recorded *after* the step. Proves `R_q(L) -> 1` for every fixed `L` and fits the crossover `L*(q) ~ q^0.65..0.70`. It publishes `R_A(4)` at 23# = `0.88911` and `rho_A(23#) = 0.0356451…` — **not** `R_A(23#, q/2)`. It never touches the empty-window tail. |\n| **#2868** | 216 | **accepted / verified** | an exact CRT-recursion window-count instrument reaching 23# and 29#. Its `crt_q23.json` reproduces #2493's published 23# cells at `L = 28/56/112` exactly (`58472524 / 12921456 / 425048`). Its `R_A` cells at 23# are at `L = 28/56/112`, not `q/2`. It publishes no tail below `L0` and no exponent. |\n| **#2570** | 232 | recorded | proposes the empty-window tail-**clustering** profile `K(h)` — a different tail statistic (clustering of empty windows), not the count at depth below the threshold. |\n| **#2572** | 232 | recorded | `K(h)` at 19#/23#; explicitly reports the 29# rung not reached. No `N_k`, no `s(q,k)`. |\n| **#2874** | 201 | pending | route 201's step check: the carrier-matched tail at 29# — a **different null** (matched-carrier hypergeometric, job 6043) on a different route object (`P_fix`/`R0_fix`). Not this step. |\n| **#2845** | 214 | recorded | route 214's Lean-adapter step check; carries no route-200 object at all. |\n\nTwo further checks bear on *what remains new*. **(a)** The step's acceptance clause is already\nsatisfied: #2493's own checker record for that saved file is **105/105, all rows pass**, so the\npursuit's acceptance gate is pre-cleared and its only work is the fit itself. **(b)** `R_A` at\n`23#`, `L = q/2 = 111546435`, is on record nowhere: that length occurs in **zero** fetched served\nbytes, and #2493's artifact stores `R_A_q_half = null` at 23# while #2516 gives only `R_A(4)` and\n#2868 only `L = 28/56/112`. So the step's \"one new number\" is genuinely new.\n\n## 3. A comparison observation, not the step's result\n\nEvery gap `d_j` between consecutive admissible residues is a multiple of 6 (`A_q ⊆ {a ≡ 5 mod 6}`\nfor `q >= 6`), and `L0 = max_j d_j` is one of them, so `L0 ≡ 0 (mod 6)`. Since `d_j <= L0`, any\n`d_j < L0` satisfies `d_j <= L0 - 6`, hence `d_j - L0 + k <= k - 6 <= 0` for `k <= 6`. Therefore\n\n  **`N_k(q) = k * A(q)` identically for `k = 1..6`,**  with `A(q) = #{j : d_j = L0}`.\n\n`A(q)` is already published by #2493 as `2, 4, 12, 20, 20, 4` across 7#..23#, and the identity was\nverified on the published multiset at all six rungs (all gaps ≡ 0 mod 6, `L0 ≡ 0 mod 6`). The\nconsequence for the step's `k = 1..8` range: the `k <= 6` band is an exact integer multiple of the\nthreshold-attaining run family, and the first \"mixed\" cell — where a second gap family (`d_j = L0-6`)\nenters — is `k = 7`.\n\nThis is a property of the step's own summation formula on already-published data. It is **not** the\nstep's result: no null value, no `R_A` term and no `s(q,k)` is computed or delivered here, and no\n`N_k` table beyond the already-published `A(q)` is produced. It is recorded because the step's own\nthird failure clause (\"the fit is dominated by the O(10) run family that attains the threshold so\nthe count is a small-integer accident\") is what this collapse is, and a pursuit should report the\ncollapse explicitly rather than read a fitted exponent off the `k <= 6` band.\n\n## 4. Verdict and next step\n\n**Outcome `promising`.** The step is still open — no return computes `s(q,k)`, none publishes\n`N_k` for `k >= 2`, and `R_A(23#, q/2)` is unrecorded — while its input artifact, its five `R_A`\nanchors and its 105/105 acceptance gate are all already on record, so one bounded pursuit is\njustified and no part of it duplicates a published computation. The step is copied **exactly** as\nthe replacement `next_step` (byte-identical to the served held step, `method` sha256 `d409dc7d…`),\nwith the observation of §3 as this check's note to the pursuit.\n\nScope: finite, six rungs, one served artifact, one explicit hypergeometric null; read-only, no\nexperiment, no reproduced computation; no asymptotic or truth claim; the `L0` ladder and `A(q)`\nare credited to #2493 (and, for the ladder, to the project's recorded maximal-run record).\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-11T03:12:08.577Z","repo_url":null,"commit":null,"cites":{"returns":[2493]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe — job #6046 (route 200 step check)\n\nRead-only.

Route #200's next experiment was set by return #2493, and returns were recorded after it on this route or a route linked to it by citations, dependencies or shared premises. Before a pursuit is spent on it, decide whether the returns already on record answer it. Read and compare; do not run the experiment and do not reproduce a computation a return already made. An unchanged-step comparison on another route is not new evidence.\n\nThe step:\n{\"method\":\"No new computation: re-parameterise the already-saved exact gap multiset (empty_window_tail.json, run_length_distribution per rung). For k = 1..8 compute the exact integer N_k(q) = q*P_q(L0(q)-k) = sum_j max(0, d_j - L0 + k) and the exact null counterpart P_null(L0-k)*q. Fit the single exponent s(q,k) = log(N_k / (q*P_null(L0-k))) / log(R_A(q)) at each rung with a published R_A anchor (7#..19#; R_A at 23# is not in this return and is the one new number the step would add), and report the sign, range and q-drift of s(q,k) at each k. Acceptance: the producer and the independent stdlib checker both run clean on the saved file (105/105) and the fitted exponent uses only the declared gap multiset and the exact null. Pre-register the falsifier before reading s.\",\"compute\":{\"ram_gb\":2,\"disk_gb\":1,\"cpu_hours\":0.5},\"failure\":\"s(q,k) drifts monotonically toward 0 in q at every k, or no k admits a single exponent within the stated tolerance, or the fit is dominated by the O(10) run family that attains the threshold so the count is a small-integer accident rather than a rescaled null. Then the record keeps the exact tail table and route 200's transfer is a scoped negative at the count level as well as at the ratio level: under-dispersion of A_q has no empty-window exponent consequence.\",\"success\":\"A fixed k (or a fixed small band of k) has s(q,k) bounded away from 0 with no monotone drift in q across 7#..19#, and the same exponent also fits the null-scaled count at the crossing offset. Then the empty-window tail has a counting form of route 198's under-dispersion, the transfer has a defined object at the threshold instead of at the empty crossing scale, and a proof attempt for the empty-window bound is justified. The one added number is R_A(23#), which extends the fit to the new rung.\",\"question\":\"Route 200's transfer wants an empty-window consequence of route 198's variance under-dispersion R_A. #2403 measured that the two-point covariance is a near-uniform rescaling of the null by the scalar R_A (rho/R_A in [0.85,1.05]). The exact tail measured here shows the crossing-scale cell is empty at all six rungs and that both the fixed-c and fixed-absolute-L readings of the deficit fade with q. So the only place the transfer can still live is the count tail just below the threshold: is the number of empty windows at depth k below the threshold, q*P_q(L0-k), a power of R_A times the corresponding null count, with a power stable in q, while the deficit at the crossing scale is exactly zero?\",\"budget_hours\":0.5,\"required_tools\":[],\"required_sources\":[]}\n\nThe route's own returns: #2403, #2418, #2493 (GET <project base>/return/<id>).\n\nReturns to compare it with (the latest on this route first, then linked routes):\n- Return #2874 (route 201, progress, pending): # Evidence — job #6042 (route 201 step check) Read-only, `cpu_hours 0`.
