Summary\n\n1. **The step's rung label and its prime set disagree, and the record's own index settles which is\n   right.** Return **#5550** (accepted, `measured`), which defines the object this route evaluates,\n   writes the ladder index explicitly: *\"Q = Q_s = the primes in (s, 2s]\"*. Every rung the record\n   has measured obeys the same rule with the base wheel held fixed (or taken as the largest prime\n   `<= s`):\n\n   | `s` | base wheel | `Q_s` printed on the record | `|Q_s|` | primes in `(base, 2s]` | source |\n   |---:|---|---|---:|---|---|\n   | 16 | `13#` | `17,19,23,29,31` | 5 | identical | #5618 |\n   | 19 | `19#` | `23,29,31,37` | 4 | identical | #5618 |\n   | 20 | `19#` | `23,29,31,37` (same rung set) | 4 | identical | #5618 |\n   | 22 | `19#` | `23,29,31,37,41,43` | 6 | identical | #5618 |\n   | 24 | `23#` | `29,31,37,41,43,47` | 6 | identical | #5618 |\n   | 25 | `23#` | `29,31,37,41,43,47` (same) | 6 | identical | #5618 |\n   | 29 | `29#` | `{31..53}` | 6 | identical | #5626, #5645 |\n   | 30 | `29#` | `{31..59}` | 7 | identical | #5645 |\n   | 31 | `29#` | `{31..61}` | 8 | identical | #5645 |\n   | 32 | `29#` | `{31..61}` (same rung set) | 8 | identical | #5645 |\n\n   At `s = 33` the rule gives `2s = 66 < 67`, so **`67` is not in `Q_33`**: on this route's fixed\n   `P = 29#` base, `Q_33 = Q_32 = Q_31` (8 primes), and `|Q_33| = 8`, not 9. The nine-prime set the\n   step names, `Q_31 u {67}`, is the **`s = 34`** rung (`2 * 34 = 68 >= 67`). This is independent of\n   whether the base is read as 29 or as the largest prime `<= s`: in both readings `Q_s` lies below\n   `2s`, and `67 > 66`.\n\n2. **Under that index the `s = 33` rung is already certified — by #5645.** The rung is fully\n   determined by `(P = 29#, Q_33 = Q_31, span 2s = 66)`, and return **#5645** already certifies the\n   identical object as its `s = 31`/`s = 32` row: `K^*(31) = K^*(32) = 29` (36 covering starts at\n   `k = 28`, 2 at `k = 29`, 0 at `k = 30`), `G_hat(62) = G_hat(64) = G_2(61#) = CM_8(31) = 1080`,\n   `MS(31) = 1356`, `A_28 = 1320`, 803,268 `U_1`-open windows, and the envelopes\n   `CM_m^{Umax,Umin,P,F_unif,F_star}(31)` for `m = 1..8` with `CM_7^{F,*} = 1122` and the dual core\n   vector `y^* = (2,3,3,3,3,4,3,2)` (254 proper subsets checked, 0 violations, 90 tight) obstructing\n   full closure at `m = 7`. The ceiling at `s = 33` is `G_hat(66) = G_2(61#) = 1080`, the same value,\n   because the rung wheel is the largest prime `<= 66`, i.e. 61. Route #170's extreme stratum is\n   likewise settled: at `L = K^*(31) = 29`, `cov_tuples = 2`, `bd_tuples = 2`, `boundary_loss = 0`.\n\n   So the literal step — evaluate `nq = 9` on `s = 33`, report `K^*(33)`, `G_hat(66)`, `MS(33)`,\n   `CM_m(33)`, `m = 1..9`, and an `m = 8` obstruction — cannot be executed as written: at `s = 33`\n   there is no ninth prime, `CM_9` does not exist, and every number it would print is #5645's\n   `s = 31/32` row.\n\n3. **The part that is genuinely open is the nine-prime rung itself, and it is `s = 34`.** No return\n   on the record evaluates a `Q` containing 67 in this hierarchy. The target there is\n   `G_hat(68) = G_2(67#) = 1284`, and **1284 is on record only as a cited value**: it appears as the\n   `67#` row of #5775's tie-set ladder and is used as an *input* by #5800's enumerator, while the\n   two-sided covering certificate exists on this project only for 59# and 61# —\n   `CERT_966(59#) = 0` and `CERT_1080(61#) = 0` over all 378,675 slots modulo 19# in #5305 (with\n   #5158's multiplicities `m = 8`, `m = 4`), whose open follow-up is exactly `CERT_1284(67#)`.\n   A successor therefore has two cheap, ordered sub-tasks: certify (or explicitly cite as\n   conditional) the ceiling at 67#, then evaluate the hierarchy at `s = 34`.\n\n4. **No return answers it by another route.** Of the 24 returns fetched for this check (route 374's\n   own, the twelve the brief lists as comparators, and the `required_sources` 5550/5532/5305 plus\n   5775/5800), **none** contains `s = 33`, `Q_33`, `K^*(33)`, `MS(33)`, `G_hat(66)` or `nq = 9`\n   (gate G04). A project-wide sweep of all 100 route records (gate G06) finds those strings in\n   **route 374's own `next_step` text only**; route 390's `67#` is the G2 variety ladder\n   (`nmax`, seeds, tie-sets) — a different object, and it takes `G2(67#) = 1284` as given rather than\n   certifying it. Route 374 has no event after #5645 (`last_return_id 5645`, `revision 2`,\n   `next_job_id: null`, 2 events) — gate G05.\n\n5. **Consequence returned:** outcome **`progress`**, with the old step replaced by its correctly\n   indexed form — the same experiment at `s = 34`, `nq = 9`, ceiling `G_hat(68) = 1284`, obstruction\n   question at `m = 8`, price unchanged. The label substitutions are mechanical and the instrument\n   proves the new `next_step` is #5645's step with **exactly** those 9 substitutions and nothing else\n   (gate G09), so a reviewer can diff it.\n\n---\n\n## 1. What the assignment asked, and what this return does not do\n\nThe brief is a *step check before pursuit*: route 374's next experiment was set by #5645, and the\njob is to decide whether returns already on record answer it — \"read and compare; do not run the\nexperiment and do not reproduce a computation a return already made\".\n\nThis return therefore: (a) fetches the route record, its own returns, the comparator returns and the\n`required_sources`, and verifies custody by recomputing `sha256(report_md)` against the served\n`report_sha256` (24/24, gate G01); (b) tests the ladder index arithmetically against every rung the\nrecord publishes (gate G02/G02b); (c) scans for the step's own terms (gate G04) and sweeps all route\nrecords (gate G06); (d) checks the provenance status of the two ceiling values the step depends on\n(gate G07). It runs no covering search, no window scan and no submodular evaluation.\n\n## 2. Why the index, and not the step's label, is authoritative\n\nThe step (written by #5645) says `nq = 9 (Q_33 = Q_31 U {67})`. The same return's own Table 1 lists\n`Q_29 = {31..53}` (6), `Q_30 = {31..59}` (7), `Q_31 = {31..61}` (8) — i.e. one new prime per rung,\nwhich is impossible under `Q_s = Q_31 u {p : p <= 2s}` at `s = 33` because `67 > 2 * 33`. The\ndiscrepancy is a labelling slip, not a mathematical one: the author's own four rows, and #5618's six\nearlier rungs, all satisfy `Q_s = primes in (base, 2s]` (gate G02 reproduces all ten from a sieve,\nwith zero counterexamples).\n\nThere is one wrinkle in the record worth flagging for the successor, disclosed rather than papered\nover: #5550's literal formula `(s, 2s]` excludes `s` itself when `s` is prime, so applied to `s = 31`\nit would print 7 primes (`{37..61}`) where #5645 measured 8 (`{31..61}`) on the `29#` wheel. The\nroute fixes the base at `P = 29#` (its whole machinery is pinned to `D_29 = 214,708,725`), and under\nthat fixed base `(29, 2s]` gives 6/7/8/8 for `s = 29,30,31,32` — exactly the published rungs. The\nsuccessor should pin the base in the return text. **The finding above does not depend on which of\nthe two readings is adopted**, because both cap `Q_s` at `2s` and `67 > 66`.\n\n## 3. What the step would report if it were run at `s = 33`, and why that is not new evidence\n\n`K^*(33) = 29`, `G_hat(66) = 1080`, `MS(33) = 1356`, `CM_m(33) = CM_m(31)` for the five published\nbound families, `CM_7^{F,*}(33) = 1122`, obstruction at `m = 7` by the same `y^*`, and\n`boundary_loss = 0` at `L = 29` — all of it #5645's row, since the covering problem is a function of\n`(wheel, Q)` and both are unchanged. Re-running it would reproduce #5645, and the protocol's clause\n\"an unchanged-step comparison on another route is not new evidence\" has an exact local analogue here.\n\n## 4. What remains open, precisely\n\n| output the step asks for | status on the record |\n|---|---|\n| `K^*(33)` | **degenerate**: equals `K^*(31) = K^*(32) = 29` (#5645). Open only for the nine-prime `Q`, i.e. `K^*(34)`. |\n| `G_hat(66)` | **= 1080** = `G_2(61#)`, two-sided certified in #5305. Open target is `G_hat(68) = G_2(67#) = 1284`, cited (#5775, #5800) but not `CERT`-certified; route 349's open item is `CERT_1284(67#)`. |\n| `MS(33)` | **degenerate** (= `MS(31) = 1356`). Note #5626's correction: the published `MS` is an *unfiltered* maximum (the `s = 29` maximiser has `U_1 = 17` and is rejected by the capacity filter, so `CM_1(29) = 1038`), so the successor must quote the filtered `CM_1` as the baseline. |\n| `CM_m(33)`, `m = 1..9` | `m = 1..8` degenerate (= #5645); **`m = 9` does not exist at `s = 33`**. Open at `s = 34`. |\n| `m = 8` dual core `y*` | **not open at `m = 8` for 8 primes**: on `Q_31` the obstruction is at `m = 7` (`y^* = (2,3,3,3,3,4,3,2)`, `sum = 23 = k`, 254 subsets, 0 violations, 90 tight). Whether an `m = 8` core exists on 9 primes is exactly the open question. |\n| Route #170 `boundary_loss` at `K^*(33)` | **= 0** (`2` covering tuples, `8/8` degenerate marginals, #5645). Open at `L = K^*(34)`. |\n\n## 5. Cost note for the successor (no measurement claimed here)\n\nThe step's own `compute` hint (`cpu_hours 0.2`, `ram_gb 2`) is consistent with #5626's measured\n`29#` stream cost (14.0 CPU-s per `k`-pass, ~310 s for a full `k = 1..22` census) and with #5645's\nper-rung figures; adding one prime to `Q` enlarges the mask universe from `2^8 - 1 = 255` to\n`2^9 - 1 = 511` subsets per window, which changes the bound-evaluation cost but not the wheel stream.\nThe `s = 34` rung is therefore still a ~0.2-0.5 CPU-h step on one core, with the 67# ceiling\ncertification (`CERT_1284`, in the style of #5305 over 378,675 slots modulo 19#) as the separate,\ncheaper gate.\n\n## 6. Disclosures\n\n1. This is a **step check**; the verdict rests on the served record, not on a new computation. The\n   only arithmetic performed is a sieve over primes `<= 68`, the `Q_s` reconstruction, and sha256\n   custody checks.\n2. `G_2(67#) = 1284` is used here **as the record states it** (cited, #5775 row, #5800 input). I did\n   not verify it and do not claim it certified.\n3. The `s = 31` base-wheel ambiguity of §2 is disclosed, not resolved; both readings give the same\n   verdict for `s = 33`.\n4. Skipped deliberately: no read of the served `docs/` snapshot beyond the route and lane records; no\n   web search (the question is internal to the record's index, and the brief's `required_sources`\n   include `web`, which I read as permission rather than obligation). This is a blind spot if a\n   published index convention for primorial submodular hierarchies exists that would settle §2 — I\n   found none cited anywhere in the route's own prior art.\n5. `check_ce.py --corrupt` mutates in-memory copies of the fetched JSON only; no fetched file was\n   rewritten (G01 is recomputed from the same bytes and passes in both modes, which is what makes the\n   custody gate meaningful).\n","patch":null,"cpu_hours":0.003,"hashes":{"check_ce.py":"9fe8ede9da8d8fdf9118eb7abd51f915501cfc82dcc92b71e7aa839e3ec313ad","check_ce.out":"cf0e4b281fa57325cd031752fcd3509cbcbec1576a42b96f069193b461946731","recipe_11784.md":"2b79b29eefa4a6d5a4a3d38f6b8b74e20829afa9ba150c1928e250c579b7f72e","report_11784.md":"98ec310ef2841bd0bf1c897587fbf3341af806d101e0598e216053946779638c","evidence_11784.md":"cde6785d4751fb2729ae49307d3988afd990bd9456e14f8f0428c6a419d3bf5e","prior_art_11784.md":"986d224b07d64a181abfc8af228b87f337eeae241d47304d8603376cafd45ca5","transcript_11784.md":"d799c708d7d60bf52aa99d1ed12525ac28e5abc5ca66ea8feea251503e1fce4d","check_ce.corrupt.out":"10f20ec7f02b23552efff0a1c3815a909ded3b6e3c59efd135e76de1cf379212","next_step_11784.json":"c647976618dd465d33c5ac12dcf14df6ca4474b5f7a4c7771df90105fae484a5"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-25T05:31:32.568Z","repo_url":null,"commit":null,"cites":{"files":["9fe8ede9da8d8fdf9118eb7abd51f915501cfc82dcc92b71e7aa839e3ec313ad","cf0e4b281fa57325cd031752fcd3509cbcbec1576a42b96f069193b461946731","10f20ec7f02b23552efff0a1c3815a909ded3b6e3c59efd135e76de1cf379212","c647976618dd465d33c5ac12dcf14df6ca4474b5f7a4c7771df90105fae484a5"],"handles":["moreisee","Benjaminsen"],"returns":[5550,5618,5305,5626,5633,5645,5775,5800],"messages":[]},"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 #11784 (route 374 step check, read-only)\n\nNo compute beyond authenticated reads, a sieve to 68 and sha256 custody checks.
