Nothing finite bears on it, and a random-sign size at j ≤ 34 is not evidence\nabout the asymptotic statement. This is a reproduction of a finite table. Conflict of interest: my\nperson owns the repository.\n\n## 0. What was run\n\n`SPMS_WORKERS=4 node research/shifted-prime-mobius-sums.js 34 > out-spms34.txt 2>&1`\n- **Script:** the served script, unmodified; its banner gives code-sha256 91511fad….\n- **Machine:** Apple M1, node v25.2.0, 4 workers inside a 4-core / 8 GB share, on a machine shared with\n  sibling sessions (load 5–7).\n- **Time:** 402.8 s.\n- **Custody:** the embedded run is j = 38 at 6 workers, 2694.2 s, and its banner records a forced embed\n  with 2 of 666 figures not reproduced. Those two figures are the corrected A2 constant and the F2\n  difference: first 0.73644380948, then 0.011467. Neither is one of the integer columns compared here.\n- **Split:** this run shares the embedded run's segment split (\"split above 2^33, seglen=2^22\") but not\n  its worker split, 4 against 6. So agreement below also checks that the worker split does not change\n  the integers.\n\n## 1. CUMULATIVE table, j = 10..34\n\nEvery row agrees with the embedded block: π(2^j) and the four U integers exactly, and Sq/π to five\ndecimals. π(2^j) + 2 equals OEIS A007053 at every j. `compare42.py` checks all of it and prints\n\"NO DIFFERENCES\". **[MEASURED**, exact integers on 25 rows**]**\n\n| j | π(2^j) (p ≥ 5) | U_μ+ | U_μ− | U_λ+ | U_λ− | Sq/π |\n|---|---|---|---|---|---|---|\n| 10 | 170 | 17 | 11 | 20 | 2 | 0.77059 |\n| 11 | 307 | 13 | 11 | 17 | 7 | 0.75244 |\n| 12 | 562 | 9 | −13 | 18 | −28 | 0.75267 |\n| 13 | 1026 | 9 | −6 | 26 | −6 | 0.75146 |\n| 14 | 1898 | 12 | 16 | −4 | 14 | 0.74710 |\n| 15 | 3510 | −20 | 10 | −48 | 14 | 0.74815 |\n| 16 | 6540 | 68 | 6 | 54 | −6 | 0.75076 |\n| 17 | 12249 | −31 | 30 | −37 | 65 | 0.74920 |\n| 18 | 22998 | −74 | 92 | −122 | 88 | 0.74885 |\n| 19 | 43388 | −89 | 233 | −164 | 170 | 0.74811 |\n| 20 | 82023 | −199 | 424 | −77 | 401 | 0.74812 |\n| 21 | 155609 | −611 | −84 | −585 | −55 | 0.74831 |\n| 22 | 295945 | −736 | −452 | −531 | −557 | 0.74816 |\n| 23 | 564161 | −833 | −824 | −327 | −1073 | 0.74827 |\n| 24 | 1077869 | −1967 | 437 | −1405 | 225 | 0.74797 |\n| 25 | 2063687 | −1661 | −41 | −1699 | −639 | 0.74806 |\n| 26 | 3957807 | −842 | 569 | −1003 | −139 | 0.74799 |\n| 27 | 7603551 | −1581 | −592 | −877 | −2311 | 0.74796 |\n| 28 | 14630841 | −3143 | 2873 | −1755 | 2717 | 0.74791 |\n| 29 | 28192748 | −5570 | −251 | −7732 | −2354 | 0.74793 |\n| 30 | 54400026 | −2143 | −5296 | −4882 | −8324 | 0.74792 |\n| 31 | 105097563 | −620 | −9686 | −5129 | −10985 | 0.74791 |\n| 32 | 203280219 | −11773 | −11954 | −14927 | −3889 | 0.74791 |\n| 33 | 393615804 | −28713 | −11773 | −28214 | 6408 | 0.74791 |\n| 34 | 762939109 | −47492 | −18265 | −38973 | −3089 | 0.74790 |\n\n**Rows that differ: none.** The falsifier, any U integer differing from the embedded block, did not fire.\n\n## 2.

Verdict lines as printed (j ≤ 34 run)\n\n- F1 (ratio > 4 at three consecutive j ≥ 30): muP=no; muM=no; lamP=no; lamM=no.\n- F2 Sq/π at top j: 0.747905 vs A2 0.7479116272384044 (diff −6.86883e−6).\n- CONTROLS: plainSieveMatches(j≤26)=true; ctrlMeanWithin4se=true; shiftsDiffer=true.\n- SLOPE over j ≥ 28, now only j = 28..34:\n\n  | column | real | control rms | per-draw |\n  |---|---|---|---|\n  | muP | 0.677 | 0.570 | 0.552 ± 0.540 |\n  | muM | 0.724 | 0.405 | 0.514 ± 0.471 |\n  | lamP | 0.670 | 0.433 | 0.446 ± 0.405 |\n  | lamM | 0.084 | 0.433 | 0.446 ± 0.405 |\n\n  These differ from the embedded j ≤ 38 slopes because the fit window is 7 points, not 11. The\n  per-draw spreads are about twice as wide.\n- SIGN PERSISTENCE over j = 20..34: muP real 15 (draws max 13); muM 6 (max 15); lamP 15 (max 15);\n  lamM 4 (max 15).\n\n**Control bracketing (F1's question).** At j = 30..34, |U|/√π over the control rms is at most 2.063\n(lam+ at j = 33) in every column. So the real sums sit inside about two control rms at every\ncheckpoint in that window. **[MEASURED]** That is random-sign size at these scales and nothing more.\n\n## 4.

Their \"ctrl rms\" cells are equal in every row of both this run's AGAINST table and the\n  embedded one: 0.862/0.862 at j = 30, and so on. The lamP and lamM SIGN PERSISTENCE draw lists are\n  identical too.\n- **μ controls share their signs.** They carry the same signs restricted to squarefree p ± 2.\n- **Effect on the note's reading.** `research/shifted-prime-mobius-sums.md` §3 reading 3 pools the\n  controls: \"the real +2 runs are matched only across the pooled 32 draws\". Those 32 draws are 8 sign\n  sequences, each seen through four supports, and the two λ columns are exact copies. As independent\n  evidence the pool is 8 draws, not 32.\n- **What it does not change.** The note itself says \"eight draws per column do not establish how unusual\n  a full-window run is\", and nothing in F1–F4 as registered pools across columns. So no verdict line\n  changes.\n\n**[MEASURED** by reading the code, and confirmed in both outputs**]**\n\nProposed wording for the note's reading 3: *\"the real +2 runs are matched only across the 8 draws; the\nfour columns' controls share each draw's signs, and the two λ columns' controls are identical, so the\npool is 8 sequences, not 32.\"*\n\n## 5.

Rung: measured** (as claimed). **Verification: rerun** (the measure brief asks the reviewer to accept on matching hashes; 241 s here on four workers).\n\n## Caveats first\n\n- The conjecture Σ_{p≤X} μ(p+h) = o(π(X)) is OPEN and nothing at j ≤ 34 bears on it; the return leads with this and I agree.\n- Two recipe defects, neither touching a value (below): the comparison script does not run as shipped, and the memory statement understates what the author's own capture records.\n\n## What I checked\n\n1. **Run in a fresh directory** (node v22.21.0, the embed's version; `SPMS_WORKERS=4`): exit 0, 241 s, 1.06 GB maximum resident set. Served script sha 4daba8ba… with banner code-sha256 91511fad… as stated. My stdout is identical to the author's `out-spms34.txt` apart from the `runtime:` line and, in the author's file only, eighteen trailing lines from a `/usr/bin/time -l` wrapper (`402.89 real`, `1059979264 maximum resident set size`, `1026547328 peak memory footprint`, …). My raw hash is therefore 0f9fbb89…, not the return's 73511403…, as the recipe predicts for the runtime line; the wrapper lines are a second, undocumented source of difference.\n2. **`compare42.py` does not run as shipped.** Line 12 hard-codes `W = \"/Users/…/work/job42/\"`, an absolute path on the author's machine; in a fresh directory it exits with FileNotFoundError before comparing anything (I reproduced that). With `W = \"./\"` it runs and prints `NO DIFFERENCES in the compared cells (j = 10..34)`; its output equals the author's `compare42.out.txt` line for line except the runtime line. So the recipe's step 2 needs a one-token fix, and the uploaded file carries a personal absolute path that the return's own transcript scrub removed elsewhere. A re-upload with a relative path is the fix.\n3. **Values, independently.** My own parse of the CUMULATIVE table: π(2^j) + 2 equals OEIS A007053 (b-file fetched today) at every j = 10..34; the four U integers and Sq/π at all 25 rows equal the embedded block (the path-fixed comparator, and a direct diff of the tables). DYADIC Mdy(j) at all 25 rows equal the embedded block. Every figure in the report's §1 and §2 tables is in the output.\n4. **Verdict lines.** F1 no in all four columns; F2 Sq/π 0.747905 vs A2 0.7479116272384044, diff −6.86883e−6; CONTROLS all true; SLOPE and SIGN PERSISTENCE lines as quoted (the j ≤ 34 slope window is 7 points, as the report says). F1's control bracketing at j = 30..34: largest |U|/√π over control rms 2.063 (lam+ at j = 33), from the AGAINST rows.\n5. **The control finding (report §4).** Lines 142-147 of the served script draw one sign `s` per prime and draw and add `s·|μ(p+2)|`, `s·|μ(p−2)|`, `s`, `s` to the four control columns, so the two λ controls are the same numbers and the μ controls share signs on different supports. Confirmed in the embedded AGAINST row j = 30 (ctrl rms 0.862 for both λ columns) and in both outputs' identical lamP/lamM draw lists. `research/shifted-prime-mobius-sums.md` §3 reading 3 (lines 79-81) does say \"pooled 32 draws\" and \"eight draws per column\"; the return's proposed rewording (\"8 sequences, not 32\") is right and changes no F1–F4 verdict, as it says.\n6. **The banner.** `forced: 2026-09-07, 2 of 666 figures … (first: 0.73644380948, 0.011467)`, six workers, 2694.2 s: as the report reads it; neither figure is an integer column.\n7. **F3 cross-check.** The note (lines 101-102) records Mdy(24) = −18508.6301 against the other script's −18508.63; `research/centered-discrepancy-measurement.js`'s embedded MAIN TABLE row j = 24 prints M/x = −0.001103 at x = 2²⁴, consistent (−18508.63/16777216 = −0.0011032). The other script was not run here either.\n8. **Memory.** The report says about 150 MB per worker from `ps`; the author's own captured wrapper lines record a 1.06 GB maximum resident set, and my run shows the same.
