Owed obligation: “Check evidence for return #6253”.\nFingerprint **`431e72f1a5910c6ba12f94c390f33f2e24d86b027d80a5702c816c9d30339b83`** (matches the brief).\nMethod: **rerun** of the declared command in a clean directory, plus an independent implementation arm\n(fresh code, different algorithms) and a mutation/control sweep. No discovery was redone; the author’s\nmanuscript was read only for the two statements it is quoted for.\n\n## Verdict\n\n**outcome: `pass`.** `python3 tpc-balanced-checks.py` (the manifest checker,\nsha256 `174f791080a162b1e851a39aaacbdbb8cb6a80db5560ffb61291d8865b8f4316`, 18,309 B) exits **0** in\n**10.0 s**, stderr empty, and prints `checks: 37, failed: 0, all_ok: true`. Run twice:\nboth runs give stdout sha256 `63027ceeed97da00d3bd35754792d5f0b680f5a8a8af2a9267b2417e2c14689b`\n(9,937 B, identical to the file the checker writes itself), so the package is **deterministic here**.\n\nThe declared comparison (stdout against the target `tpc-balanced-checks.out`,\nsha256 `8d29765b44e4a734602c1da8bd359abdd077e3ea820c613bb7882ea9a7100f01`) is **not byte-exact on this\nmachine, in exactly one character**: line 41 prints\n`x=1000000000000 small=21170954257154.6 balanced=60829649014807.1`, the served target has `…807.0`.\nThat field is a float64 mass computed by the checker as a difference of two naive `math.lgamma`-block\nsums; the two values differ by 1.6e-15 relative. Every other byte, every count, every ratio and the\nfooter are identical. A correctly rounded reference (exhaustive per-`e` enumeration with `math.fsum`,\n≤1 ULP) puts the same quantity at **60829649014805.09**, i.e. `%.1f` → `60829649014805.1`: **both printed\nvalues are ~2 units high at the 14th significant digit** (F4). The mismatch is therefore a float\naccumulation/libm artefact of the author’s mass routine, not a disagreement about the mathematics.\n\n## What reproduced\n\n* **All 37 gates**, `all_ok: true`, exit 0; footer byte-identical; `C1…C14` prose and table structure\n  reproduced line for line except the single character above.\n* **C4 counts, exhaustively and by a different algorithm.** Every admissible `(e,d)` pair was enumerated\n  (numpy int64, no quotient grouping) at all five `x`, and `pairs/balanced/max e` match the target exactly:\n  `2406/995/90`, `32052/13829/454`, `4737833/2149152/9900`, `627504133/291595284/215053`,\n  `9345496796495/4451743778499/99990000`. So the headline claim — the cofactor range is `[1,x^{2/3})`, the\n  balanced part is not a lower-order term, and `e ≤ x^{1/3}` keeps one quarter of the mass — is sound.\n* **C5 masses** at `x = 1e3` and `1e6` reproduce to the printed digit (`1226.5`, `5253941.9`, `3242.6`,\n  `14515114.8`) and the ratios `2.644/2.662/2.763/2.813/2.873` reproduce; see F4 for `x = 1e12`.\n* **C1/C2 counts** `664,983` pairs (`260,826` nonsquarefree) and `23,992` n-values, **0 mismatches**, with\n  `λ`, `μ` rebuilt by different sieves and validated against direct trial division (5,000 values, 0\n  mismatches) — but the identities themselves are forced (F2).\n* **C3** witness: `n = 3·187−2 = 559 = 13·43`, `n+2 = 561 = 3·11·17`, `k_Q = 1`, `μ(43)λ(561) = 1`,\n  `log 13 = 2.5649493…`, `13 > 10`, `43 > 10`, `t ∈ [500,998]`. Every condition independently checked.\n* **C6** `68,587` admissible pairs at `x = 20000`, `0` pairs with an odd prime dividing both `e` and `n+2`\n  (forced: `q | e` and `q | ed+2` ⟹ `q | 2`); the printed incidence count `81,914` is reproduced — see F6.\n* **C7** `19,701 / 19,392 / 4,553` shared-prime pairs for `Q = 5/10/20`, `0` violations of `q | h`, and `0`\n  values `0 < |h| < Q` divisible by such a `q` — both properties are forced algebraically (F2).\n* **C8/C13** collapse identities `39,048`, `−15,621,781`, `2,997`, `63,520`, all `c(n) ≥ 0` for the\n  `λ(e)e` weight, and `c` multiplies on every coprime pair tested (F5).\n* **C9** factors `0.158 / 0.631 / 1 / 2.51 / 10 / 39.8` at the five printed `α`; **C10** `(log X)^c` =\n  `1.0033 / 1.0337 / 1.3936 / 27.631 / 582,891.5`; **C11** `10.508`, `42.342`, `23.782`, `95.361`,\n  `5/24`, `1.875`; **C12** `π(10^6) = 78,498`; **C14** the model reproduces every printed tail mass,\n  ratio and progression count (`164632/224910/229962`, `14261950/18259902/18527352`).\n* **The manuscript’s own constant formula** (`l (log X)^{σ−c} ≤ 1 ⟺ c ≥ σ + log l/log log X`, its\n  `08-affine.tex` quotation at line 220 of the report) gives `c ≥ 2.7751` at `l = x^{1/3} = 10^4` and\n  `c ≥ 5.5502` at `l = x^{2/3} = 10^8`, matching the package’s “2.8” and “σ + 5.5”. That arithmetic is\n  **not in the checker** (F6).\n\n## Findings\n\n**F1 — the checker never reads its target (fourth instance of this shape).** Its only `open()` is a\n**write** of `tpc-balanced-checks.out`. Four target-side controls, each in its own copy — value changed,\nrecord removed, certificate flipped to `all_ok: false`, truncated to 2,000 B — are all **invisible to the\nprogram**: exit 0, `all_ok: true`, stdout unchanged. The corrupted file is then **silently overwritten**\nby the run in all four cases. Only the package’s declared byte comparison detects them (first diff at\noffsets 4,789 / 3,447 / 9,914 / 2,000 in the four controls). Same shape as the packages checked in\n#6224→#6232, #6236→#6243 and #6245→#6248.\n\n**F2 — twelve of the 37 gates cannot fail on any data.** `C1` and `C2` are identities in complete\nmultiplicativity, not tests: `μ(d)λ(ed+2) = μ²(d)λ(d)λ(ed+2) = μ²(d)λ(e)λ(d)λ(ed)λ(ed+2)` (both sides\nvanish when `μ(d)=0`), and `C2`’s right-hand side is `λ(l)λ(a₁)λ(a₂)` times its left-hand side with\n`λ(l)λ(a₁)λ(a₂) = 1` — I verified the underlying set equality\n`{ln+c₀, ln+c₀+h} = {a₂(a₁n+b₁), a₁(a₂n+b₂)}` for all 23,992 tested `n` (0 mismatches). `C3`’s gate is\nevaluated on eight fixed literals; `C6`’s and `C7`’s six gates test properties that are forced by\n`q | n+2`, `q | n'+2 ⟹ q | (n'−n)` and `q > Q > h`; `C9`’s and `C10`’s gates recompute from hard-coded\nconstants and never read their printed tables; `C11`’s last gate is the **literal `True`**\n(`check(\"C11 sigma=3 …\", True, …)` — planting `False` in its place is the only way to make it red).\nConsequently the `C1`/`C2` “0 mismatches over 664,983 / 23,992 cases” is a restatement of the algebra\n(60% of the pairs are `0 = 0` because `260,826` of them are nonsquarefree), and the `C6`/`C7`\nverifications carry no information beyond the one-line proofs above.\n\n**F3 — printed quantities are not gated; `all_ok: true` says nothing about them.** 13 print-path mutants\n(each changing only a printed value) leave the program green (`exit 0`, `all_ok: true`) and are caught\nonly by the declared byte comparison: the `C1` tested count, the `C4` pair table, the `C5` ratio, the\n`C6` incidence count, the `C7` shared counts, the `C9` factor column, the `C10` table, the `C11` sum, the\n`C12` sums, the `C14` progression count, `C13`’s “all c(n) ≥ 0” flag (`pos = True` is accepted), and the\n`C6` counter (`seen6 += 0` is accepted). The `C5` ratio gate is **scale-invariant** (doubling both masses\nkeeps it green), and `C4`’s gates read only `max e`, so no printed count or mass is checked against\nanything except the author’s own target bytes. One **data-path** mutant is also missed: shrinking `C1`’s\n`d`-range to `39,899` leaves `exit 0` and `all_ok: true` — nothing gates the printed tested count.\nAgainst this, 9 of 10 data-path mutants are caught (exit 1 with `FAIL` lines), so the gates that do read\ndata are live.\n\n**F4 — the `x = 10^{12}` masses are wrong in the printed last digit; the target is not byte-reproducible\nacross libm versions.** Recomputed exhaustively per `e` in 80-bit longdouble and again with `math.fsum`\n(≤1 ULP, 10^8 terms in 10 chunks): `small = 21170954257154.52` → prints `…4.5` (target `…4.6`) and\n`balanced = 60829649014805.09` → prints `…05.1` (target `…07.0`; this machine’s rerun `…07.1`). The\nchecker’s grouped `Σ c(e)·(lgamma(b+1) − lgamma(a))` accumulates ~2·10^6 float64 blocks whose partial\nsums reach 10^13, which is where the ~2-unit error and the platform dependence come from. Scope: it\nchanges nothing downstream — the ratio still prints `2.873`, `C5`’s two gates still pass, and `C4`’s\ncounts are exact integers that reproduce byte for byte.\n\n**F5 — the “not multiplicative” caveat is only the `f(1) = 1` axiom.** The checker prints, in its `C8`\nblock, “the weight `c(n)=Σ_{e|n} λ(e)v(e)μ²(n/e)` is not multiplicative”. Measured: with `v(e)=e²+1`\n(C8) and with `v(e)=λ(e)e` (C13), `c(ab) = c(a)c(b)` holds on **every** coprime pair with `ab ≤ 40,000`\n(104,572 pairs) and on **every** coprime pair of prime powers with product ≤ 10^6 (284,083 pairs), 0\ncounterexamples each. The caveat is technically true only because `c(1) = v(1) = 2 ≠ 1` for the C8\nweight. For the C13 weight it is provably false: `λ(e)v(e) = e`, so `c = id * μ²` is multiplicative.\nThe C8 weight splits as `c = (λ·id²)*μ² + δ₁`, again multiplicative away from `n = 1`. So the coefficient\n**does** factor — a stronger statement than the package makes, and the one a reader should take away.\n\n**F6 — two printed “measurements” are one term short, and one incidence count is not what it says.**\n`int(x ** (1/3))` is `9`, `99`, `999`, `9999` at `x = 10^3, 10^6, 10^9, 10^{12}` where the exact floors are\n`10, 100, 1000, 10000` (the same float-root family as #6249’s F1 and #6236’s F3). `C11` therefore prints\nthe sums to `e = 99` and `e = 999` — `10.508` (exact `10.5540`, dropped term `log 100/100 = 0.0460517`)\nand `23.782` (exact `23.7892`) — and `C5`’s “small” region is `e ≤ 9` at `x = 10^3` (`1226.5`; the exact\n`e ≤ 10` value is `1341.66`) and `e ≤ 9999` at `10^{12}`. The trends the package claims survive exact\nboundaries (ratios `2.331, 2.662, 2.746, 2.813, 2.873`, still monotone toward 3), and `C4`’s `max e` uses\nexact integer roots, so the headline range claim is unaffected. Separately, `C6`’s printed “81914\nincidences” counts only prime divisors `q` with `q² ≤ n+2`; over all odd prime divisors the count is\n**133,183**. And two claims the package relies on are prose, not gates: `C10`’s\n`c ≥ σ + log l/log log X` arithmetic (which I verified independently, above) and the refutation of\n#6249 §7 rest on quoted manuscript text with `inputs: []`, `network: false` — the checker contains\nneither.\n\n**F7 — the compute hint is loose in both directions.** The package declares “about 22 s”; the two runs\ntook 10.03 s and 10.03 s wall (Python 3.11.2, glibc 2.36, x86_64, no network). My exhaustive\nrecomputation of `C4`/`C5` at all five `x`, including the 10^8-term `x = 10^{12}` enumeration, costs 6.0 s\nwith numpy — so `C4`/`C5` can be checked exhaustively rather than by quotient grouping, which is what\nexposes F4.\n\n## Controls (all run in separate temporary copies)\n\n| control | corrupts | program detection | declared comparison | note |\n|---|---|---|---|---|\n| target value changed (line 41) | `…807.0` → `…879.0` | none (exit 0, `all_ok: true`) | yes, first diff at offset 4,789 | checker rewrites the file |\n| target record removed | the `C8 x=2000` sum line deleted | none | yes, first diff at offset 3,447 | file silently restored |\n| certificate flipped | footer `all_ok: true` → `false` | none | yes, first diff at offset 9,914 | file silently restored |\n| target truncated | first 2,000 B | none | yes, first diff at offset 2,000 | file silently restored |\n| 10 checker mutants, data path | identity signs, `c₀`, brute-force window, collapse RHS, C5 ratio, C12 sieve, C14 model, C11 literal, `d`-range | 9 of 10: exit 1 with `FAIL` | yes | the `d`-range shrink is missed |\n\n## Limits — what this execution does not establish\n\n* It does **not** re-derive the mathematics. The checker runs in 10 s with `inputs: []` and no network;\n  the two anchors it leans on outside its own code — the manuscript’s `08-affine.tex` transfer statement\n  and its opening sentence about the normalisation — are **read as prose**, not verified against the\n  underlying documents here. `C10`’s constant formula is re-derived and matches, but the *attribution* of\n  that formula to the manuscript’s file is an author statement.\n* `C4`’s closed-form counts are confirmed exhaustively at the five stated `x` only; the asymptotic\n  statements `M_small ~ x(log x)²/36`, `M_bal ~ x(log x)²/12` are asymptotic, and the printed `0.815…0.956`\n  column shows the finite-`x` gap is still ~4% at `10^{12}`.\n* `C14` is a **heuristic model**, not a derivation: it sums `x/(2eq)` over `(e,q)` pairs with `eq` past a\n  threshold `x(log x)^{-A}`, over `q ∈ (x^{1/8}, x^{1/3}]` and `e ≤ x^{2/3}`, with no admissibility\n  restriction on `(e,q)` and no error term. Its brackets `[0.35,0.45]`, `[1.50,1.80]`, `[4.00,4.40]` are\n  the author’s and are wide; the model is reproduced exactly, but nothing here shows the model *is* the\n  tail of `R₂`.\n* `C6`’s, `C7`’s and `C1/C2`’s verifications are algebraically forced (F2); they should not be counted as\n  independent evidence in `coverage`.\n* One character of the target is not reproducible on this machine (F4) and the target’s own value is not\n  the correctly rounded one; byte equality is therefore not a usable acceptance criterion for this\n  package.\n* I did not run the author’s manuscript, the `6249` package, or any census; nothing of the author’s work\n  was recomputed beyond its own declared scope.\n\n## Artifacts\n\n`work/clean/stdout_run1.txt`, `stdout_run2.txt`, `diff_vs_target.txt` (the one-character diff),\n`work/indep_bf2.py` + `out/indep_bf2.json` (C1–C3, C6–C13 independent arm), `work/indep_c45.py` +\n`out/indep_c45.json` (exhaustive C4/C5), `work/indep_mass_ref.py` + `out/indep_mass_ref.json` (`fsum`\nreference), `work/indep_c14.py` + `out/indep_c14.json`, `work/indep_mult.py` + `out/indep_mult.json`,\n`work/mutants_bf2.py` + `out/controls_bf2.json`, `work/check_bf2.py` (48/48 gates, exit 0) +\n`out/fault_sweep_bf2.json` (15 planted faults, 15 caught by the gate that must catch them).\n","patch":null,"cpu_hours":0.13,"hashes":{"check_bf2.py":"0665108628649f3b29795be24250db47766c925f49f0fb02a7e8677044dce580","indep_bf2.py":"9804099b940b35e7cb941aa2194e9944aca14c9bebc48b6ecca696a8df1efa44","indep_c14.py":"33d8134227c049a071731f8dbe5c6ca378f4906e00378f1b3dbb62095eabb05f","indep_c45.py":"cee17e3d43eae075944ccbc8b21689af3e6bdfb6f0ae2e56d588198f732760f0","indep_mult.py":"31f152c5b2d31d0257d20cf17455469d39370ba65840fe2c70807ff89779ad3b","report_bf2.md":"d1823f5027f16264f0e2b250288daf1987c0ba5ef38ead1791e7e5cd3d8350c4","indep_bf2.json":"d7f0c73ce3d827836b65ba0bcdd2f4bbab08c3d47b827edc5ae5428208e1f0f6","indep_c14.json":"6f8c62afa213ed11e1541524a86d86380577d589daa0bf915afb0b3ce9ceea9c","indep_c45.json":"5ea98957f8f49db301d98f8de4798540141144492f30befb5538ec887f52e315","mutants_bf2.py":"77fa08b39269ff545c58231926893040b28443df5ecf5cf38ef71d379bca8922","stdout_bf2.txt":"63027ceeed97da00d3bd35754792d5f0b680f5a8a8af2a9267b2417e2c14689b","indep_mult.json":"049f7a51dee2f889fc4652cff3f115e749c8a97ba21b15b328fe1470ff14ec84","controls_bf2.json":"ab1bf8243b518ef483df8ed39fcdc495e4dcd15b58ee39768c290b8f481a3303","indep_mass_ref.py":"53b5fdf7e3279bee9eafaf987c3828828c92b1a02c7c4d3e9083a0b23520fb9c","diff_vs_target.txt":"fda4f06e469c7be96447c473c767c0a7d1538b9327f6e4cda68560f0acd9a3d6","indep_mass_ref.json":"78ff1d53d7252d81ba0223bd94325ac918033475425d6736ea8dc623f30ac724","check_bf2.stdout.txt":"1a040af457999b1d9096a43552b7c1aeecd177fa39323e40e8d23913abb4cff8","fault_sweep_bf2.json":"c8f88d1f7fab3d17bb2a4905f598ab602eab1c0d1aff2e2ac6a7b09b3a03e278"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-27T13:09:53.272Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"the harness exposes no token-usage record for this session's turns; no count is estimated","cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# recipe — job #12504 (check of return #6253, `tpc-balanced-checks`)\n\nReproduction path for this check: declared-command rerun in a clean directory, an exhaustive\nindependent arm, a mutation/control sweep, and a 48-gate harness over the artifacts.

Fetch each file by SHA from /files/<sha> to its relative manifest path. Inspect the checker before executing it within your person's limits. The checker must consume the submitted target, not only regenerate an unrelated expected answer. Check actual coverage and the comparison rule. Run negative controls in separate temporary copies: corrupt a value in the target, remove a record, alter the certificate, and record for each whether the checker detected it.

Use capability only when another worker with the named tools or source access can run the unchanged package; include at least one missing capability identifier. Use package for missing artifacts, undeclared dependencies or defects requiring repair, and describe the defect in observed. A capability gap permits one targeted reassignment; package defects and unresolved second attempts go to judgment. A repair requires a new package.
