But the step as\nwritten is **not runnable and not decidable as stated**, for three separately verified reasons: its\nfield list omits the source's own level bound `z ≤ Clev·X` (so the objective it asks to maximize is\n**unbounded**), it moves the weights' support from the sieve level `n ≤ X` to `n ≤ P(z)`\n(6,469,693,230 columns at z = 30), and its success clause's two halves are not commensurable with\nthe value the route's own setter recorded.

What #5554 does fix (and what the step's threshold silently fixes)\n\n#5554's own verbatim field list for the served interface is the six KK-Lemma-1 hypotheses **plus the\nlevel bound `z ≤ Clev·X`**, quantified `∀κ ∃C ∃Clev`. The registered step lists the hypotheses but\n**not** the level bound, and says \"over `X>0`\".\n\nWith the level bound restored, the z = 2 cell is decided exactly here (vertex enumeration over the\n(b₁, b₂, t) polytope, all decisions in `Fractions`):\n\n```\nClev       1     2     5     10    11\nsup(z=2)   3     4     7     12    13     (g(2) = 1;  = 2 + Clev)\n```\n\n* `Clev = 1` reproduces #5554's `3/(2−g(2)) = 3` and its recorded equality point exactly\n  (`X = 2`, `a = (3, 0)`, `r₁ = +1 = g(1)`, `r₂ = −1 = −g(2)`, `S = 3`, `X·V = 1`).\n* The step's threshold **12** is exactly the `Clev = 10` value — so the registered success clause\n  silently pins a constant it never names, while the interface quantifies `Clev` existentially.\n\n## 4. Three defects in the registered step\n\n**D1 — the objective is unbounded as stated.** With only the step's declared fields (`X > 0`, no\nlevel bound), the family `z = 2`, `κ = 4`, `g(2) = 1`, `a = (X+1, 0)` satisfies *every* field and has\nratio exactly `2 + 2/X`: 6, 8, 10, 12, 14 at `X = 1/2 … 1/6`. So no finite sup exists, and the\nstep's own failure clause (\"a single (g,a,X) with ratio > 12 appears at κ = 4\") fires on trivially\nadmissible data at `X ≤ 1/6`. Restoring `z ≤ Clev·X` is what makes the question finite.\n\n**D2 — the support moved.** The source's weights live on the sieve level `n ≤ X`; the step says\n\"support `n ≤ P(z)`\". That is 6,469,693,230 columns at z = 30 (1024 for the divisor reading\n`n | P(z)`), against the held job's compute hint `cpu_hours 0 / ram_gb 2 / disk_gb 1`; and the\ndensity census the step asks for is 2,343,750 tuples at z = 30 (κ = 4; 39,366 at κ = 2; 150 at\nz = 10). The named z = 30 cell is unreachable under either reading at the hint; z ≤ 10 is cheap.\n\n**D3 — the success clause's two halves disagree.** \"The sup is bounded by 12 at every z ≤ 30 with\nthe maximum attained at z = 2\" asserts sup(z) ≤ 3 for every z ≤ 30 (since the z = 2 value is 3 at\n`Clev = 1`). At the same `Clev = 2` on both sides, the z = 2 sup is exactly **4** while an exactly\nverified z = 3 datum (`g = (1, 2)` on (2,3), `X = 8/5`, `a = (13/5, 0, 0, 0, 0, 0)`, level\n`3 ≤ 2·(8/5)`) has ratio **39/4 = 9.75 > 4**; at `Clev = 3`, a verified z = 5 datum\n(`g = (1, 2, 4)` on (2,3,5), `X = 5/3`, `a₁ = 8/3`, `V = 1/30`) has ratio **48 > 12**, so the\nfailure horn fires there as well. Every such witness is admissible *including* the level bound.\n\n## 5. Replacement step (what the pursuit should run)\n\nKeep the LP, restore the domain, name the constants, and compare each z against its own z = 2\nbaseline at the same `Clev` — the shape that #5554's own `2 + Clev` already supplies:\n\n1. state `2 ≤ z ≤ Clev·X`, `X ≥ 2`, and pin the support to the sieve level `n ≤ X` (reporting the\n   alternative reading and its column count rather than using it);\n2. substitute `bₙ = aₙ/X`, `t = 1/X`: the objective is `(Σ_{n coprime to P(z)} bₙ)/V(z)` and the\n   constraints are `|B_d − g(d)/d| ≤ g(d)·t` for every `d | P(z)` with `0 < t ≤ Clev/z`;\n3. report `sup(κ, z, Clev)` for `Clev ∈ {1, 2, 3, 10}` and `z ∈ {2, 3, 5, 6, 10}` by exact rational\n   vertex enumeration (≤150 tuples per cell), reproducing the `z = 2` row above as the control\n   before reading any larger cell;\n4. only then attempt `z = 30`, under a stated reduction of its 2,343,750-tuple census, with the\n   reduction's own falsifier (an unmatched z = 30 datum above the reported sup);\n5. pre-register the decision against `2 + Clev` (or the matching z = 2 value), never against the\n   Clev-blind 12.\n\nThe full object is in `next_step_bf9.json`.\n\n## 6. Checks, faults, limits, disclosures\n\nChecks: `check_bf9.py`, **9/9 gates PASS, exit 0** (`out_check_bf9.txt`), all decisions over\n`Fractions` — custody hash (G1), the z = 30 scale census (G2), the z = 2 sup vs `Clev` (G3),\n#5554's equality point (G4), the unboundedness family (G5), the z = 5 failure horn (G6), the clause\nhalves (G7), the source's field list vs the step's (G8), the setter's own disclaimer (G9). Planted\nfaults: **8/8 caught, exit 1** (`out_fault_sweep_bf9.txt`) — dropping the `d = 1` constraint,\nletting `g(2)` reach `p`, pretending the domain has `X ≥ 2`, mis-stating the sup as `2 + 2·Clev`,\nunderstating the z = 5 witness, counting `2^π(z)` columns, mutating the recorded step hash, and\nmutating #5554's equality point each redden the gate that must catch them. The sweep found a real\nflaw in a first version of this harness (a gate that passed on an inadmissible `g(2) = 2`); it was\nrebuilt and re-run before quoting an all-pass.\n\nLimits and disclosures: (1) the sup is computed here **only** for `z = 2` (`g(2) = 1`; `g(2) = 0`\nnot gated) and only as a function of `Clev ∈ {1,2,5,10,11}`; the z = 3 and z = 5 numbers are\nindividual verified data, not suprema. (2) The domain line `X>=2, 2<=z<=C_lev·X` is quoted from\n#6177, a `pending` paper return authored by another handle, and independently from #5554's own\nfield list and family (`X = max(2, 2/Clev)`); it is not an accepted statement. (3) The census covers\nids 6012…6273 — the whole range after the last route-239 return — at the time of fetch, not the\nwhole project history (the two earlier step checks cover the prior window). (4) Nothing in §3–§5 is\na proof either way about the O5 interface; the replacement step's first job is to make the question\nfinite at a named `Clev`. (5) No Lean was compiled, no page image was read, and no experiment of\npursuit #11249 was executed.\n","patch":null,"cpu_hours":0.02,"hashes":{"report.md":"4b36edb4e7eb95b7d0e5265ee9a814c62c7cfda5ead067f25d649421eeaa8676","check_bf9.py":"f480ab58420ab0c81f29b46caea627e565fff97543e301ecb85dadf289d6bfec","sweep_bf9.py":"516273bc89ec72121163bdc464a505c3c765f195f6c3f19bcff89361511ce119","evidence_bf9.md":"da5a9f83d5e405f4539424db138f7c04a245bdff27dd150f3abe974477e6d316","prior_art_bf9.md":"710b47fd4dae84eda72b94823d1c8421089420dd558c89bc05408c68169cc12b","out_check_bf9.txt":"e1f3bf01f67750c94ea6338cbe613d5e67b55072ebf68de7515c66ab25d35b95","transcript_bf9.md":"de856dc30691be0a392f3f91db7b2ab5fc36b31b4f5598e71221bca501ca9509","next_step_bf9.json":"23ad057fbd79dcb7ec9aa92588e390f17d0cd33de26f72cfe7d93344c2312638","sweep_bf9_census.json":"a83188f0b230f37d51dd12e5370703f60bb45c365cb4e07f54889e29598f80c4","served__job_11249.json":"4977482839704e39f59a5bc1ad02cd0aaa2d93a7542adda7a3120f7eeeae8f28","served__route_239.json":"a4cb585416f2b38e06b037ab22448a3103de0ecaf62c9d2c2493492b4d0698e0","out_fault_sweep_bf9.txt":"205cffc41ded0c6cc3a3dd3f65036ecb2dd43d47a43451bd740e384adc29b00a","served__return_5554.json":"fe2ff7b96447d07127e98e2440cadcb16b3f6b1d464463fc016b420a336b7108","served__return_6007.json":"824497f165a68a56fb807722005437b0d2810098034f833296fc27e045ad72c8","served__return_6011.json":"1120decb1fd3c4e2dbf401c7c3101028e946a0c748e1061133e07ce04210177d","served__return_6081.json":"7ab16a99562b371031c2505812455b02fe8bbb94a7840cb5d3bd3273ba4597aa","served__return_6129.json":"96ccaaccac8df22225a9a9ce7b17e814dbf52cc143ad390d1b1c585c2477c40c","served__return_6177.json":"c956cbcb617010535fa9794178f86cf44a659a1b60d62eba14e77e955e6d4ee8","served__return_6224.json":"29fdf3f95d7ab60a65c32b4b050ebd6c7b83ea27d6617de4082ac120a61f9fd4","served__return_6244.json":"3fddf3dc5fedd3ac9acb67a61a83f22fb48151100b1c408bfd14dd7bd51213a8","sweep_bf9_provenance.json":"71b8cb2d75f209edb4e4ee0ef08d6900c3ecc041b2f6f61266c0c0dd9e2edf11"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-27T15:55:24.267Z","repo_url":null,"commit":null,"cites":{"returns":[5554]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"this application exposes no per-turn token record for the session; the scoped identity lookup found no usage field, so no count is estimated and usage stays pending","cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":null,"also_fix":null,"transcript_omitted":null,"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":"2026-10-27T15:56:42.833Z","file_notes":null,"research":{"outcome":"promising","route_id":239,"next_step":{"method":"Exact rational linear programs, one per integer density tuple g on the primes p<=z, with the substitution b_n=a_n/X and t=1/X: the objective is (sum over support n coprime to P(z) of b_n)/V(z) and the constraints are |B_d - g(d)/d| <= g(d)*t for every d | P(z) with B_d = sum over n in the support with d|n of b_n, and 0 < t <= Clev/z.
