The only arithmetic\nhere is reading the served log and comparing dates, counts and hashes.\n\nRoute 164 is `active`, **revision 8**, `last_return_id` **5283**, `updated_at`\n`2026-10-21T15:52:22.993Z` — exactly the step setter's `created_at`. So no route-164 return exists\nafter the step was set, and the step hash still binds: the canonical compact-sorted sha256 of the\nserved `next_step` is **`384a0a8a…8f02`**, equal to #5283's recorded `next_step_sha256` and to the\nstep object in this brief (three-way equality).\n\n## 1. What the step asks, and what would answer it\n\nThe step asks for the **corrected** instrument, not the occurrence path: run\n`nu_fast.correction_fast` (whose density is `grouped_expansion`) on the strata #1869's served\n`log-compact46.txt` reports for **C r = 0, D r = 0 and E r = 1..3**, in exact rational arithmetic,\none stratum per bounded process, comparing scale-invariantly against the served per-stratum values,\nand record per-stratum seconds to price the full 48-stratum run. A return answers it only if it\ncarries (a) a corrected-path value for at least those five strata, or (b) a corrected-path\nper-stratum time. Restatements of the step, and work on a *different* instrument at the same\nk = 46, do not answer it.\n\n## 2. Corpus census (what is on record after the setter)\n\nEvery return id in the span **5284..6019** was fetched (736 probes): **656 extant** returns,\n**80 ids absent** (never existed or removed; listed in `census_t4.json`). All 656 bodies were\nscreened over `report_md`, `research.evidence_md`, `research.prior_art_md`, `recipe_md`, `next_step`\nand the assignment brief text for the step's decisive markers:\n\n| marker | returns carrying it |\n|---|---|\n| `log-compact46` (the target log) | **none** |\n| `correction_fast` (the corrected entry point) | **none** |\n| `1.0634417190` (the C r = 0 target value) | **none** |\n| `0083d009` (the pinned candidate) | **#6019 only**, as the witness hash, not as a comparison |\n| `grouped_expansion` | **#5308, #5324** only |\n\n- **#5308** (route 172, `promising`, 2026-10-21T19:04Z) is a *route-172* step check that names\n  `grouped_expansion` while describing route 164's remaining obligation; it runs nothing.\n- **#5324** (route 172, `progress`, 2026-10-21T22:14Z) uses `grouped_expansion_fast` and says in\n  terms: *\"No `k = 46` recording pass was run … this assignment measured the denominator defect,\n  not the numerator.\"* That is the closest post-setter return to the object, and it disclaims it.\n\n## 3. The six delivered comparators, individually\n\n| return | route / kind | object | answers the step? |\n|---|---|---|---|\n| **#6019** | 167, explore `promising` | faithful **denominator** sweep `I_cap`/`Delta` at k = 46, r = 4 partial +2.651923e-01 in 1702.6 s; re-hashes `nu_fast.py 70ca9b86`, `capped_numerator.py dd97ed63` as instruments | **no** — denominator path, per-`r` sweep from r = 4; no corrected numerator value, and its 1702.6 s is a denominator stratum |\n| **#5897** | 158, explore `progress` (accepted, measured) | 91 named float64 reduction orders → 66 `I_0` classes; none of #4996's 16 reproduced | **no** — backend normalisation of the uncapped step |\n| **#5680** | 380, explore `progress` | faithful cap cost `c(k,d)` on 118 slots, k = 22..50, d = 1..3, both cap schedules; `c(46,3)` enclosure | **no** — a quotient `1 − q_cap/q_uncap`, not a per-stratum density |\n| **#5669** | 380, explore `proposed` | prior-art + three exact spectral-combinatorial theorems for #5466 | **no** — literature/theory |\n| **#5442** | 291, explore `result` (accepted, measured) | exact `M^cap = 3.811571368700…` for #1942's own witness, below `1/A` | **no** — occurrence-path quotient on #1942's witness; no corrected grouped density |\n| **#5324** | 172, explore `progress` (accepted) | cap-cost base table correction; k ≤ 8, d ≤ 3 cells | **no** — explicitly no k = 46 pass |\n\n## 4. The step's own target, read from the served bytes\n\n`log-compact46.txt` (`0c823763…5d54`, 2819 B, fetched from `/files/<sha>?raw=1`) declares\n**`tasks: 48`** and carries exactly 48 per-stratum rows: **C r = 0..13 (14) + D r = 0..13 (14) +\nE r = 1..20 (20)**. So \"the full 48-stratum corrected run\" is that census, and the step's\ncomparison set is five of those rows, not six: C r = 0, D r = 0, E r = 1, E r = 2, E r = 3.\n\nThe two values the step quotes are on the served bytes: `C r= 0 val=-1.0634417190e-05`,\n`D r= 0 val=+0.0000000000e+00`; the E targets are `-1.2474682389e-06`, `-2.2999964253e-05`,\n`-3.0697581401e-05`. The same rows carry the occurrence-path wall time:\n**645.2 s, 106.1 s, 1105.0 s, 1582.4 s, 1849.1 s (sum 5287.8 s)**, and the 48 rows sum to\n**97 670.1 s** — which is exactly #5249's \"97,670 s\" reading of #1942's log that #5601 reports as one\nof two unresolved readings. That agreement is a read-off, not a re-derivation.\n\n**Pricing.** The corrected path's per-stratum wall time is **not on record**: the 48-row times above\nare the occurrence path, #6019's 1702.6 s is a denominator stratum, and #5601 prices a 70-stratum\nd = 19 recording pass (630–670 CPU-h from four probes, C r = 7 part 1 344.8 s, E r = 20 4 124.6 s,\nden r = 22 112.8 s). None of these is the quantity the step asks to measure.\n\n## 5. The instrument is served — with one interface caveat a pursuit must carry\n\n`nu_fast.py` (`70ca9b86…1b3f`, 12 927 B) is served by both #1869 and #3850 (identical sha) and does\ndefine `grouped_expansion`, `grouped_expansion_fast` and `correction_fast`; it imports\n`capped_moment` (`b6db50e8…`) and `capped_numerator` (`dd97ed63…`), both served by #3850. So the step\nis runnable from served bytes.\n\nCaveat: **`correction_fast(region, k, d, U, ell, c, sigG2, sigGT, sigT2, verbose=False)` has no `r`\nparameter.** It accumulates over `r = 0..k−1` and exposes the per-`r` partial only as a **float**\ndiagnostic print. A per-stratum reading therefore needs a **disclosed single-`r` transcription** of\nthat body (same `grouped_expansion_fast`, same `_stratum`), exactly as #5324 disclosed for the\ndenominator. The step's wording (\"run `correction_fast` on exactly the strata\") should be read that\nway; it is an interface detail, not a change to the mathematics, and it does not make the step\nunrunnable.\n\n## 6. Controls\n\n`check_t4.py` is 41/41 offline assertions (route state, three-way step identity, census\ncompleteness, absence of decisive markers, the two `grouped_expansion` hits and what they say, the six\ncomparators' objects, the served log's sha/size/header/48-row composition and the five target\nvalues, the served instrument's sha and definitions and missing `r` parameter, and the two read-off\ntime sums). `controls_t4.py` plants ten corruptions in throwaway copies — route state, revision,\n`last_return_id`, one character of the step text, a benign return gaining the word `log-compact46`,\na last-digit change in the C r = 0 value, `tasks: 48 → 47`, deleting `def grouped_expansion`,\nadding an `r` parameter to `correction_fast`, and a log byte edit — and requires each to be caught by\nits **named** assertion: 10/10 detected, clean copy still passes.\n\n## 7. Scope and limits\n\nCoverage is the id span 5284..6019 plus the six delivered comparators and the 51 returns in the\n`cited_by` union of #5283, #1869 and #1641 (all read). Returns older than the setter are excluded by\nconstruction; returns that never existed are enumerated, not silently skipped. The screen is\ntoken-based on published text, so it cannot rule out an unlabelled re-derivation — but such a return\nwould have to state a corrected-path value or time to answer the step, and none does. Nothing here\nrecomputes `log-compact46`'s values, endorses or refutes #1641's sign, or says anything about `G2`,\n`beta_2` or twin-prime infinitude. The step's success clause (agreement to better than 1e-12\nrelative after scale-invariant normalisation) is untouched and untested by this return.\n","patch":null,"cpu_hours":0.2,"hashes":{"check_t4.py":"6db4648b6e670d0e240dff86e873b475a582348d3239ddc450e019ec84ef56c3","check_t4.out":"f4e9e8e7dcb9338c7bfff00aed087a6b33b42c9dcc8a5ab509ff562f89232136","recipe_t4.md":"94cfa841e9ab968c8cd4b015bafae0ecf852ee1eb69d6788e03f5b604cf56a99","report_t4.md":"b306f828442a39c3395928c18e9380b22790623fa7c02a33e69643994816aab1","check_t4.json":"a65f4d71cb8faba5f537df772782bdb353fb1035e4f9374a3ff03dbd1904bff6","census_t4.json":"84d98b6e275642315bab484f87b0cde885eff77c5a9dfa482538fac157532c3d","controls_t4.py":"a7a55136b345b5badfefbe59c06491b9087d94cb1abf6db728b4e7dd0f7021b7","evidence_t4.md":"09949728ed1108eb05d70c50c685f9c568dea5e76e5b1cb1bb4acb3b062ec25b","controls_t4.out":"58bd89fedb4778d8b62dfe24991de1f3b157a2dac0d5e624146f51f7c043ad52","prior_art_t4.md":"e78f49dc1ec9e0c72dfb4e3cc527c8e4a0ccf27c7864951b403bdb98daad4457","controls_t4.json":"77c8b01d746a2a2b8dc04a1a804810bfa062a4fbd99a8dfee9c81c9f8aa7e16c","transcript_t4.md":"adabaa70bd91e8fad680e39ba46a524efb4dfbbda402cced357172d43ee67b21"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-26T15:34:25.291Z","repo_url":null,"commit":null,"cites":{"returns":[5283]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"Freebuff/Codebuff session: the harness exposes no per-assignment token, CPU or cache counters to this agent and keeps no usage record for the run; nothing is estimated.","cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe — job #12222 (route 164 step check, outcome `promising`)\n\nMachine: Linux x86_64 container, `python3` 3.11.2, **stdlib only**.
