Job #12215, `check`,\nstage `consolidate`, tier 3, no route/direction, one assignment. Minimal report reader: this check\nexecutes the package, re-derives its numbers and tests its coverage; it does not judge the mathematics\nand does not repair anything.\n\n## 0. Verdict\n\n**pass (execution and numbers), with coverage limits stated in §4.** All three declared files are\npresent, hash- and size-exact; the checker runs unmodified at its declared invocation with exit 0, empty\nstderr and stdout **byte-identical** to the served target, twice more to itself. Every quantity it prints\nis reproduced by an instrument written for this check that shares no code with it. No mathematical claim\nof #6062 moves: I1 (the printed Lemma 3.2 of #6057 is false as printed) is confirmed and its argument\ncompleted, the corrected form (I2) and the Region II sums (I3) are confirmed at the tested windows, the\nH1 count erratum (I4) is confirmed against #6057's own program, and I5/I6 reproduce exactly.\n\nWhat must **not** be read from this receipt: that `all_ok: true` establishes the inequalities. Three of\nten checker mutations keep `all_ok` true and the checker never reads its target, so the byte agreement is\nan external comparison, not something the program asserts about itself. The analytic content — the\nproofs of Lemma 3.1 and of the corrected Lemma 3.2, the Granville–Shao input with the two clauses the\nreport supplies, the level reduction, Region I — is read, not executed, here or anywhere in the package.\n\n## 1.

The two programs share no function names or code\n(`h1…h6`/`_divs`/`_phi`/`h_set` vs `i1…i6`/`j_pair`/`t_abs_derivative`).\n\n## 2. Independent re-derivation (`z7-indep.py` → `z7-indep.json`, exit 0, 1.1 s)\n\nOwn smallest-prime-factor sieve for μ, own adaptive-Simpson quadrature, `J2` by exact antiderivative\n(the package uses Simpson with n = 400/200), an explicit C^∞ bump instead of hard-coded integers.\n\n* **I1** — explicit bump, peak exactly 1 at 2, support (1.5, 2.5): only integer in the support is 2;\n  total variation **2.000000**; `∫t|w'|` = **3.9999999995**, so the bracket is **4.0 ≤ 5** and the\n  checker's asserted majorant is confirmed rather than assumed; LHS = −1.0; printed right side at\n  B = 1e12 with C = 1, c = 1/2 = **0.3610196202** (checker: 0.36102) → violated. The general claim needs\n  B → ∞; I computed the threshold where the right side drops below the left side: log10 B = 9.00 (C=1,\n  c=1/2), 73.68 (2, 0.25), 2.07e8 (1e6, 1e−3), 4.33e6 (1e9, 1e−2) — finite for every fixed (C, c), so\n  the printed form fails for all of them, though at B = 1e12 only the first is already violated. The\n  manuscript's \"for every fixed choice of C, c\" is exactly right.\n* **I2** — numeric bracket **308.000000** (= 2n0), bound with the lemma's 2C factor 210.6639 (the\n  checker prints the C-only value **105.3319476924**, identical to mine to every printed digit), LHS −1\n  → satisfied; the mechanism the report describes (bracket ≥ n0 ≥ A, right side growing) is real.\n* **I3** — the four printed sums reproduce **exactly to 3 dp**: −66035.764 / −303430.86 / −36661.922 /\n  −726242.653 (X = 4e4 and 1e5; d = 1 and 15). With the **true** bracket (numerically differentiating\n  `w_d`) and the lemma's 2C factor the bounds are 6.566e6 / 4.948e6 / 1.948e7 / 1.505e7, all satisfied,\n  with |sum|/bound ≈ 0.005. I also computed the **second** inner sum of (3.1) (r = 2a,\n  n ∈ (U/2, √X/2)), which the checker never tests: −175485.177 / −414040.338 / −415863.125 /\n  −1164335.928, within the same form.\n* **I4** — 183 squarefree integers ≤ 300, **33 489** pairs, **0 mismatches** (checker identical).\n* **I5** — exact rational 31939847/4084080 = **7.820573299** (checker 7.820573) against\n  (log 17)² + 1 = 9.0270979; the crossover is **1e60** by exact integer comparison: 1e60 ≥ (60 ln 10)^28\n  = 8.5168e59 while 1e59 < 5.3198e59.\n* **I6** — ratios 0.9988266611 (1e5), 0.9999868548 (1e10), 0.9999999941 (1e20), 1.0 (1e40, 1e80); the\n  checker prints 0.998827 and 1.0 (6 dp rounding).\n\n## 3.

Coverage and limits\n\n1. **I1 is arithmetic plus an argument.** The program compares the left side it hard-codes (−1) with the\n   evaluated bound at one representative (C = 1, c = 1/2, B = 1e12); it never builds the bump, never\n   integrates `|w'|` and never varies B. The manuscript says exactly this (§8). The refutation is true and\n   its argument is completed above; the program alone does not prove it for arbitrary constants.\n2. **I3 cannot see the defect it is meant to bound**: substituting the printed (wrong) exponential at B\n   for the corrected one at A leaves the output unchanged (M6), because the inequality holds with ≈185×\n   slack; only a ×1000 inflation of the sum flips it. The checker also omits the lemma's 2Cτ(r) factor\n   (conservative: the true right side is larger) and uses the report's crude per-majorant bracket.\n3. **The second inner sum of (3.1) is untested by the package**; it is asserted to obey the same bounds.\n   My instrument computed it (satisfied, ≈100× slack).\n4. **Missing keys are invisible** (M8), and the verdict wiring `all(v.values())` gates nothing on its own\n   (M2): `all_ok` is self-consistency, not coverage.\n5. **Analytic content read, not executed**: the proofs of Lemma 3.1 and corrected Lemma 3.2, the\n   Granville–Shao Theorem 1.1(b) with Theorem 2.1 input and its two supplied clauses (removal of the\n   φ(q)^{-1} projection by Lemma 3.1; the sup over summation limits by a geometric mesh), the level\n   Q = X^{1/4−ε}, and Region I's (6.2). Nothing in the package bears on these, so Theorem 6.2's\n   acceptance remains a judgment obligation — as the manuscript's §7 says.\n6. **Finite windows only**: X = 4e4, 1e5; pairs ≤ 300; Q = 17. The asymptotic statements are not\n   numerically testable; the report's own §4 says so (crossover 1e60; the moduli d ≤ 17 already carry\n   102–105 per cent of the two mixed pieces at 1e5).\n\n## 5. What I did not do\n\nNo repair, no rerun-until-pass, no second package; no re-check of #6057/#6054/#6048 beyond the excerpts\nneeded to confirm what I1 refutes and what I4 counts; no judgment of the mathematics; no review request\n— a check receipt is what this assignment asked for, and #6062 is already elevated.\n\nRung per claim: custody, execution and controls are **verified** (finite checks that ran here, with\nranges stated); the thresholds of I1 are **measured**; everything analytic remains the author's\n**proven** claim, unassessed here.\n","patch":null,"cpu_hours":0.002,"hashes":{"z7-indep.py":"f4001fe27e65e3c767949fe2121e420f75b65cf49543ad6b999c8297d09c292d","z7-indep.json":"185771e7bb85c6875a3c2cdbea9d3c096ede0624782dcfccc76578b2fdb88c1b","z7-controls.py":"0b596b9461cf9ffbc9e45b8b71f876a129096e2d4ab5caace3779d0f86c9ae18","tpc-i-checks.py":"50be6ff974cd0503092b6b72ced3a76add16878d7f002152b454521a4dea2947","tpc-i-checks.out":"a7520a06cc79b0cb5f54193361c8e8bddcc784d45e8d707ff83e28a12f0c0491","z7-controls.json":"aa555170cf19668614409bcc546c81476106d6b1a7f3a25f3ee110dd51cabdb7","tpc-i-checks.stdout.run1.out":"a7520a06cc79b0cb5f54193361c8e8bddcc784d45e8d707ff83e28a12f0c0491","return6062-check-12215-2026-10-26.md":"94506799503192ab7dcae49e6c42b3c9d47789c194729979f3280bd4e861cc8e"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-26T14:56:30.891Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"codebuff/freebuff harness keeps no token counters for this session; the run's journal records no usage figures","cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"Reproduce this check from the served package (no build step, standard library only):\n\n1.
