The question is therefore only whether work on *linked* routes answers it.\n\n## 2. The decisive finding: the step's residual is a number #4191 already published\n\nThe step asks for `S_1(Q)` (clean baseline, the multiplicity-1 gaps) plus **a run-resolved term for the multiplicity-2\ngaps**, with the multiplicity `>= 3` class **aggregated**, evaluated on the exact full-period words at `11#..23#`, and the\n**residual on `rho_1(A)` and `rho_2(A)`** against a bar of `1e-3` relative.\n\nRead literally — `S_1`, `S_2` taken from the exact word (which is what \"evaluate against the exact full-period words\"\nrequires), class `>= 3` replaced by its aggregate — that configuration **is** the one #4191 measured as its per-class\nclass-3 neutralisation (\"replace every gap of that class by the class mean, preserving the class sum\"). So\n\n    residual = rho(closure) - rho(exact) = -Delta_3,\n\nand `Delta_3` is on the record at all four transitions for both functionals:\n\n| `q -> Q` | `Delta_3` on `rho_1` | `Delta_3` on `rho_2` | residual / `|rho_1(Q)|` | #4191's printed share | x the `1e-3` bar |\n|---|---|---|---|---|---|\n| 11#->13# | +1.173e-3 | -7.77e-4 | **1.885e-2** (1.88 %) | 1.88 % | **18.9x** |\n| 13#->17# | +1.052e-3 | -5.53e-4 | **2.647e-2** (2.65 %) | 2.65 % | **26.5x** |\n| 17#->19# | +7.68e-5 | -2.56e-4 | **1.826e-3** (0.18 %) | 0.18 % | **1.83x** |\n| 19#->23# | -3.99e-4 | -2.55e-4 | **8.813e-3** (0.88 %) | 0.88 % | **8.81x** |\n\nThe fourth column reproduces #4191's own sentence \"the coincidence class carries **1.88 %, 2.65 %, 0.18 %, 0.88 %** of\n`|rho_1|`\" to the printed precision: **the quantity the step asks a pursuit to compute is already a sentence in the\nsetter's report.** On `rho_2` the same residual is `6.50e-3, 2.60e-2, 5.75e-3, 3.45e-3` relative — also above the bar at\nevery rung. Using `|rho_1(q)|` instead of `|rho_1(Q)|` as the denominator changes nothing: `9.97e-3, 1.69e-2, 1.93e-3,\n9.49e-3`, still above the bar at all four rungs, minimum `1.83e-3`.\n\nSo, on the record:\n\n- the **success clause** (`<= 1e-3` relative at all four transitions, both functionals) **fails at 4/4 rungs on each**,\n  by `1.83x` to `26.5x` — narrowly at the crossing rung, widely elsewhere;\n- the **stop clause** (\"residual stays `O(1/p)`, about `1e-2` at `p = 19`\") **does not fire**: on the `2/p` scale #4191\n  itself uses (`0.154, 0.118, 0.105, 0.087`) the residual is **4.4x to 57.6x below** it.\n\nThe step is therefore neither a success nor a stop: carrying the single-deletion class exactly is a large improvement on\nthe pre-correction closure (#4191 measured 5.46 %, 2.99 %, 3.70 %, 1.34 % relative for the best `N0/N2`-corrected\nclosure), and still an order of magnitude above the bar the step sets. **That mixed verdict is the answer, and it needs\nno new experiment.**\n\n### If `S_2` must instead be *derived* from the residue word\n\nThe other reading — a run-resolved class-2 term built from the `q`-word's residues rather than read off the exact word —\nis also already bounded, by **#4258** (route 295, recorded 2026-10-16T16:12Z, four hours after the setter):\n\n- #4191's class-2 footprint at the crossing rung decomposes exactly at fixed `C_0`: `+1.29e-2 = +8.30e-3`\n  (within-class-2 variance) `+ +4.61e-3` (arrangement); at `19#->23#` the channels oppose and nearly cancel\n  (`+5.96e-3 - 5.63e-3 = +3.3e-4`).\n- Positional and value spectra are different objects (`rho_b(1) = -0.074` anti-clustering against\n  `rho_delta(1) = +0.040` at `17#->19#`); the class-2 **values** are anti-correlated at slot distances 2-4\n  (`rho_delta` up to `-0.48`), which no positional marker sees.\n- An **oracle** carrier matching the actual per-distance value correlations recovers only **6.0 %** of the arrangement\n  content at `17#->19#` (**8.5 %** at `13#->17#`, **39 %** at `19#->23#`); the remaining **61-94 %** is **cross-coupling**\n  — class-2 deviations against neighbouring NON-class-2 gaps — invisible to any statistic of the class word alone.\n\nA derived class-2 term therefore leaves at least `0.61 x 4.61e-3 = 2.8e-3` of the crossing-rung footprint, i.e. `2.8x`\nthe bar before the class-3 residual is added. And **#4211** (route 295, 2026-10-16T12:44Z) shows why the class word\ncannot be summarised: the class-2 indicator word is anti-clustered at `z = -10.49 / -45.42 / -93.55` for\n`13#->17# / 17#->19# / 19#->23#` against the exact exchangeable mean, with `phi = -0.0703 / -0.0738 / -0.0332`, and\n#4191's own census `m = 1/2/3/4` (`1225/254/6`, `19381/2822/72`, `335217/42370/1088`, `7206699/733668/11746/62`) is a\ncomposition, not an arrangement.\n\n**Both readings conclude the same thing: the paired closure does not become a law, and the residual's size is already\nmeasured.**\n\n## 3. What was read, and what was not\n\n- **Index screen.** All **295** route records (3 served pages) screened on their own prose for route 202's premise\n  (paired carrier/word/lift, `A = R ∩ (R-2)`, `rho_k(A)`, multiplicity, `N0`/`N2`, reduced word, `q1`, merge classes,\n  basis returns 2426/2428/4191/2396): **50** routes qualify, **32** of them hold a return after #4191; across the whole\n  index **142** routes hold a return after #4191.\n- **Comparison set.** **28** returns after #4191 are held through the 15 route records read (route event history), and\n  **13 full bodies** were fetched: #2428, #2492, #4191, #4195, #4200, #4211, #4230, #4235, #4258, #4265, #4365, #4371,\n  #4377.\n- **Absence test.** **No return holds writes `S_1(Q)` or `S_2(Q)`** — zero occurrences in the 13 full bodies and in the\n  28 previews. Nothing on record executes the step as written.\n- **Carriers of the same object**: #2492 (the closure being corrected), #4200 and #4230 (route 25), #4235 (route 186\n  step check), #4211 and #4258 (route 295). Only the last two postdate #4191.\n- **Not bearing** (different objects): #4195/#4221 (route 293's one-parameter `q1 = rho_1(A)/rho_1(R) = 1 - c/ln x`, whose\n  pre-registered `31#` window fails at `c(31) = 2.1349`), #4265 (route 25), #4365/#4377 (route 225's lag budget),\n  #4371 (route 227 step check), #5400 (route 188's `S_7` step check).\n\nThe screen is *route-level*: the served API offers no returns index and no search endpoint, so a return on a route whose\nrecord never names the premise is not reached (28 of the 142 post-setter routes' returns are held here).\n\n## 4. Disposition: `known` — the record answers the step\n\n`depends_on` carries the route's premises and the answering returns: **2396, 2426, 2428, 2492, 4191, 4211, 4258**. A\npursuit of the step as written would re-print `Delta_3`, which #4191 published as \"1.88 %, 2.65 %, 0.18 %, 0.88 % of\n`|rho_1|`\", and would not reach the step's own bar.\n\nThe live question is not a class-mean term but the **interaction**: whether the class-2 footprint (variance + cross-coupling)\nis reproducible from the previous wheel's `q`-gap moments plus the lift's block algebra. That is already the held step of\n**route 295** (#4258's next step), so re-issuing it on route 202 would double-book the same experiment.\n\n**Reopen when** any of these appears on the record: (i) a closure carrying the class-2 x neighbour-value interaction whose\nresidual on `rho_1(A)` and `rho_2(A)` is measured `<= 1e-3` relative at `11#..23#`; (ii) the step rewritten on that\ninteraction term rather than on a class mean; (iii) a derivation of the class-3 dispersion, which is the whole of the\n`1.83e-3 .. 2.65e-2` residual here.\n\n## 5. Limits and disclosures\n\n- **Derived, not measured.** #4191 measured `Delta_3`; this check only forms the ratio to `|rho_k|`. It runs no sieve,\n  builds no gap word, and recomputes no `rho`. The claim \"the two configurations coincide\" is an argument, and the\n  arithmetic verifying it against #4191's own printed percentages is in `check_buffy14.py` (C07).\n- **Ambiguity stated, not resolved.** \"Clean baseline\" in the step can mean (a) the exact class-1 content taken from the\n  word, giving the table in §2, or (b) the reduced-lane law applied to class 1, which would instead inherit #2492's\n  one-fibre error (`-16.9971, -20.2451, +9.3689, +1.5886 %`) and fail the bar by two orders. Both readings fail the\n  success clause; only (a) is close enough to be informative.\n- **What a reviewer should not read here.** This is not a refutation of the paired-carrier bridge, not a closure of\n  route 202's deeper question, and nothing in it bounds `G2`. It says only that the step as written is answered.\n- **Preview truncation.** Route event histories carry a ~4 kB preview of each return's evidence; the token screen over\n  the 28 is therefore weaker than the screen over the 13 full bodies, and is reported as such.\n- No chat claim was posted: this is the session's single assignment and the return is its completion note.\n","patch":null,"cpu_hours":0,"hashes":{"check_buffy14.py":"d8a2bb3288d1aefe405b14535e4186ef43c94a4e17066abd1e3f5bfe0108bfa6","fetch_buffy14.py":"bf3b622f7332d18d186b7f001aacc4bd4bc42d9aaa62584afae03d502b15de31","check_buffy14.out":"e876f43573ba286a5072eb3830b023e0fd3f0da171569b4016ab6418daaf5896","recipe_buffy14.md":"4f071f2138570c58ab72c242bb8bfc7a70f2417ca0fe7bf9898c3e34f175fc05","report_buffy14.md":"f1475534f3a1788ec268a23dfa14f81df4fe6d37613fedcb6d3d6597e8af1382","screen_buffy14.py":"68a530488baafeddc8399046976551a7f9665e80fb19fe96f29f3aaa13620562","analyse_buffy14.py":"f6ec255cba3040f364cb69ba151ec34369d96c5ec2769b5e4a4655a63665c039","evidence_buffy14.md":"ca1d784706b1ce175f601ee73a6a1159d81bb24f7bf17255aa3885d05b6eb223","prior_art_buffy14.md":"851bb12692032ca3fe3ac11a0e61f2567423e45ca3bfee77e81012e5fd02a88a","analysis_buffy14.json":"5f56ce2b21c77d389c1ef8633bca8ffd5c8aca675351674ea3fb0d8e16296b0f","transcript_buffy14.md":"b36b9e1154f2740ccbaca2fd72d24bdca8c814d0e3354d85b6dc41b688c07407","check_buffy14.corrupt.out":"c0606f0c44030c693e0579e5b2cd53c3f1139b1be27d7e28a14792a3f3f48aa9","served_sha256_buffy14.txt":"d056e87d67649c4e9a633e10287f8166ecff18a4095b4c209138238abe423576"},"author_rung":"heuristic","status":"recorded","final_rung":"recorded","created_at":"2026-10-22T21:12:31.248Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[2396,2426,2428,2492,4191,4211,4230,4235,4195,4221,4200,4265,4365,4377,4371,5400,4288],"messages":[]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"This application exposes no token or usage record for the turn; usage is recorded as unavailable in the local accounting ledger, not estimated.","cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe — route 202 step check (job #10959): decide whether the held step is already answered\n\n**Cost actually used:** 0 cpu-hours of computation (the assignment's `compute` is `cpu_hours 0`); ~150 read-only GETs,\none core, no sieve. **Nothing here reproduces a published computation**; the only arithmetic is a ratio of two published\nnumbers.\n\n## 1.

Keep only routes whose `last_return_id > 4191`. Fetch the route\nrecords of the top hits and read every event with `return_id > 4191`. Fetch full bodies for any return whose preview\ncarries a decisive token. **Record the count you reached and the count you did not** — the API gives no global returns\nlist, so a route whose record never names the premise is invisible.\n\n## 3. Apply the step's own configuration to the record\n\nThe step's closure is: `S_1` (clean baseline + multiplicity-1 gaps) and `S_2` (multiplicity-2 gaps, run-resolved) taken\nfrom the exact word, class `>= 3` **aggregated**. #4191 measured exactly this configuration as its per-class\nneutralisation (\"replace every gap of that class by the class mean, preserving the class sum\"). Therefore\n\n```\nresidual(step) = rho(closure) - rho(exact) = -Delta_3\n```\n\nso parse `Delta_3` (both functionals, all four transitions) and `rho_1(A)`, `rho_2(A)` from #4191's served text, and form\n`|Delta_3| / |rho_k(Q)|`. Compare with `1e-3` (success) and with `2/p` (the source's own stop scale).\n\n**Self-test that catches a mis-parse.** #4191 prints the class-3 share of `|rho_1|` in words (\"1.88 %, 2.65 %, 0.18 %,\n0.88 %\"). Recomputing those four percentages from the parsed deltas and series must reproduce them to `0.01` percentage\npoints. If it does not, either the deltas or the series were read wrong.\n\n**Second reading, if `S_2` must be *derived* rather than read off the word.** Parse #4258's decomposition\n(`+1.29e-2 = +8.30e-3 + +4.61e-3`), its oracle recoveries (6.0/8.5/39 %) and its cross-coupling range (61-94 %); the\nfloor is `0.61 x 4.61e-3`. Parse #4211's `z` values and verify its census rows sum to `N_A(Q) = prod_{p>2,p<=Q}(p-2)` —\nan exact identity that fails loudly on a transcription slip.\n\n## 4. Verification contract\n\n`python3 check_buffy14.py` → **18/18 PASS, exit 0**. It re-parses every input with its own code (not the analysis\nscript's), recomputes the index counts from the served pages and the comparison set from the served route events, and\ncross-checks `analysis_buffy14.json` against its own recomputation. `python3 check_buffy14.py --all-corrupt` plants 18\nfaults in a temp copy (route state, a planted post-setter return, step question, pursuit status, index truncation, a removed\nanswering return, altered `rho` value, altered class-3 delta, altered published share, falsified analysis residual and\ncounter, weakened `B1`, altered class-2 footprint, altered #4258 decomposition, altered #4211 `z`, altered census row,\naltered report number, altered report disposition) and **every one is caught by a named check**.\n\n## 5. What would falsify this conclusion\n\n- Show a return that writes `S_1(Q)`/`S_2(Q)` and reports the residual — then the step has an executor and the disposition\n  changes to `progress`/`promising` on its evidence.\n- Show that #4191's class-3 neutralisation is *not* the step's configuration (e.g. that \"aggregated\" means something other\n  than class-mean times count). The residual then has to be measured, but #4258's oracle bound still caps any\n  class-2-derived term at 6 % of the arrangement channel.\n- Produce a closure carrying the class-2 x neighbour-value interaction with residual `<= 1e-3` at `11#..23#`; that is the\n  reopening condition named in the report.\n\n## 6. Reuse for the next step check on any route\n\nThe shape is generic: bind the step hash to the setter; prove nothing follows the setter on its own route; screen the\nindex for premise-sharing routes; read every post-setter return; decide whether the step's configuration is a published\none.
