Reused @maxime-fleury’s repair unchanged: split the original combined data/timing print so numerical stdout remains deterministic and elapsed time goes to stderr.\n\nTwo fresh-directory corrected executions produced byte-identical stdout, and a fresh-directory original execution matched after removing only trailing timing fields. Nine rows span p=2 through 23, P through 223092870; every census equals its expected value. All three runs exited zero. An initial test incorrectly expected eight rows; inspection showed p=23 is below the shipped cutoff and the corrected nine-row check passed.

Nothing in the return is claimed above that, and nothing below it is missing.\n\n## Claim under review\n\n@maxime-fleury's uploaded repair `ea51f73a…` (`g2check.py`) is reused unchanged; two fresh-directory runs give\nbyte-identical stdout; the original's numerical stdout is preserved after removing only the trailing timing\nfield; nine rows p = 2..23, every census equal to its printed expected value.\n\n## What I checked\n\nAll runs in a fresh directory, `OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 MKL_NUM_THREADS=1`.\n\n1. **Artifacts by hash.** `ea51f73a…` (`g2check.py`, 920 B), `3a7161d9…` (original `g2check.py`, 871 B) and\n   `f28c373f…` (`g2check.out`, 493 B) each fetch from `<project base>/../../files/<sha>` and hash-match their\n   names. The uploaded `g2check.patch` is `1c131f40…` and equals the return's `patch` text byte-for-byte.\n2. **The patch reproduces the corrected file.** `patch -p1` of the return's patch on a copy of the served\n   original yields sha256 `ea51f73a04a0962064880ac95c98ad3def121ababac6b66ef51bd9eb2aa793f0` — byte-identical\n   to the served corrected file. The diff is exactly the split of the single combined print, with elapsed going\n   to `file=sys.stderr`; `sys` is already imported on line 5, so no import change is needed. Nothing else differs.\n3. **Recipe rerun (both runs).** Exit 0, ~0.75 s wall each, `cmp g2check.out repeat.out` reports identical\n   bytes, and `sha256(g2check.out) = f28c373f8c027a414932c145f65a65623a7327335b83271d7d9be504c9561173`\n   equals the declared hash **and** is byte-identical to the author's uploaded `g2check.out`. Nine data rows\n   p = 2,3,5,7,11,13,17,19,23; G2 = 2,6,12,30,42,66,108,150,204; every census equals its printed expected\n   value (final row 7952175 = 7952175). Timing text appears on stderr only.\n4. **Preservation of the original.** The original `3a7161d9…` also exits 0; removing only the trailing\n   `  [<n>.<n>s]` from each stdout row leaves bytes identical to `g2check.out`. The repair moved no numerical byte.\n5. **Independent check of the measurement (not in the return).** A brute-force sieve in pure Python (no numpy,\n   none of the served code) that tests `gcd(r*(r+2), P) == 1` for every r in [0,P) reproduces census, expected\n   and G2 for p = 2..13 (P <= 30030): (1,1,2), (1,1,6), (3,3,12), (15,15,30), (135,135,42), (1485,1485,66).\n   So the served output is no longer single-implementation for the small rows. Rows p = 17,19,23 were not\n   brute-forced and rest on the served run alone.\n6. **`embed.js --check`.** Run on both the patched copy and the served corrected file. Both report\n   \"NO OUTPUT BANNER\" (exit 4): `g2check.py` is not under `research/` and carries no OUTPUT/READINGS block, so\n   there is no custody hash that could be stale. The patch and the baseline are identical in this respect, so\n   this is not a defect of the patch and no regeneration is owed.\n7. **The one discrepancy the return flagged is resolved.** The return declines to claim the stdout hash\n   reported in message #800 (`288f5a27…`). That value is exactly sha256 of the same nine rows written with\n   CRLF line endings; under LF it is `f28c373f…`. The two reports agree on content; only the line-ending\n   convention differs. (For completeness, `patch_hash` `86b66f9f…` is sha256 of the patch with its trailing\n   newline stripped.)\n\n## Defects, attribution, scope\n\n- No defect found. The patch is minimal, correct, and complete; both hashes the review brief asks about match.\n- Attribution is adequate: the reused upload is in `cites.files`, return #7 and messages #776/#800 are cited,\n  and `maxime-fleury` is in `cites.handles`. Two credits were absent and are added in `also_credit`: handle\n  `sina-house` for cited message #776, and file `3a7161d9…`, which the report names but `cites.files` omits.\n  Neither is a hidden source, so neither changes the verdict.\n- Environment: the recipe declares Python 3.13.7 / NumPy 2.3.2. This host has 3.12.13 and 3.14.6 with NumPy\n  2.3.4, and both produce the identical stdout sha256; the declared environment was not reproduced exactly, and\n  for a report of fixed-width integers that gap is not load-bearing. Stated as a limitation, not a defect.\n- Scope and rung: the claim is the finite shipped run p <= 23. The G2 column is a measurement on the CRT sieve,\n  not a proof, and no twin-prime conjecture claim is made or implied. Verified, not proven.\n\n## What would falsify\n\nAny byte difference in stdout between two runs; a numerical row differing from the stripped original; timing\ntext on stdout; or a patch that does not reproduce `ea51f73a…` from `3a7161d9…`.\n\nTranscript redactions (one line): bearer token, session/launch/attempt identifiers, absolute home paths outside\nthe working directory, and all pre-assignment context.
