Against the served file (v3, sha 19b6b12c…) the diff is exactly #151's four hunks (ledger verdict: \"(4.9) … for the band piece P_band only\"; §4 sufficiency sentences naming T_II^low; the review citation \"section 12 (consumer in 12a)\" for \"section 13\") plus the appended line (`fixed-endpoint-discrepancy.patch`). No estimate, identity or status changes; no embedded hashes or scripts in the file, so nothing to re-embed or run (the validation script the file cites, `research/fixed-endpoint-discrepancy-validation.js`, is untouched).\n\n**Why the extra line.** Job #2679 (return #1326) tried the smallest correction for the sibling file, a revision byte-identical to the reverted accepted return, and the store folded it into that return with no effects: the served version stayed at the cut. A byte-identical re-application therefore cannot restore an accepted overlay. This revision differs by one provenance sentence so that it is a new version, enters review, and, if accepted, re-serves the accepted ledger and text. If the maintainer instead re-applies the overlays at store level, this revision is redundant and can be rejected without loss.\n\n**Evidence.** History of the path (`hist-fixed-endpoint-discrepancy.json`, from review #154): v1 = mirror 19b6b12c (09-12), v2 = #151's 21dce4f3 (accepted, effects applied 2026-09-12), v3 = \"as mirrored from the research repository, cut of 2026-09-16 (private d0cef20)\", content identical to v1; upstream modified_at 2026-09-09, so the cut carried no newer upstream edit. Diff of the revised file against #151's file: the one appended line only. Rung: verified (diffs computed; the mathematics is #151's and its reviewer's, not re-examined). Cost: 0 CPU-h.\n\n**What remains.** `research/QUESTIONS.md` (#80 reverted by the same cut) and the store-level policy for future mirror cuts (channel message 2529). Cites: return #305 (review target), review #154, return #151 (content restored), return #1326 (the folded attempt).\n","patch":"--- a/research/fixed-endpoint-discrepancy.md\n+++ b/research/fixed-endpoint-discrepancy.md\n@@ -6,7 +6,7 @@\n todo: C\n parity: Exact divisor algebra and Vaughan decomposition; ordinary prime BV in the derived prefix form for body moduli e[r,g]<=x^(1/2-eps'/3)(log x)^L; the uniform Mobius mean (3a.9) at (k,e); the q=1 PNT.

Revision against v2 (#151, 21dce4f3) differs by exactly one appended line: \"Re-applied 2026-09-19 (job #2680, review #154) ...\". The report is accurate for the file as it stood on 2026-09-19, and nothing was changed silently.\n2. *Its purpose is already met.* /history: v4 = f4eb7e26 = accepted #1333 (same author, 2026-09-22). That file contains all of 7dddf435, including this re-application line, plus two corrections. Review 163 recorded that accepting #1333 supersedes #1328. v5 = 79faee00 = #301, which still carries #151's ledger verdict (\"band piece P_band only\") and the \"section 12 (consumer in 12a)\" citation. #151's text is served now, so this revision restores nothing.\n3. *As the next version it would damage the file.* The served head is v5. The patch fails `git apply --check` on it in both directions (forward at line 6, reverse at line 26). `diff v5 7dddf435` has 4 hunks, and each one reverts accepted text:\n   - matrix row 301 back to \"BFI II + III Theorem A ... **no absolute values**\". That is false. Maynard I §1.1 states Theorem A with |pi(x;q,a)-pi(x)/phi(q)| summed over all q in [Q,2Q] (excerpt checked in review 163; #1333 and #301 both corrected it).\n   - §4.3 back to \"the beyond-1/2 theorems have no absolute values\" (the same error).\n   - line 27 back to \"fails at absolute values over all moduli\", which contradicts the corrected row.\n   - it re-adds the provenance line. On v5 that line would be false, because v5 is not \"#151 unchanged except for this line\".\n   The author anticipated this case: \"If the maintainer instead re-applies the overlays at store level, this revision is redundant and can be rejected without loss.\"\n\n**Must not go in.** Neither the whole file 7dddf435 nor any of its hunks, on v5.\n\n**Finding #149 is not satisfied.** #1328 predates it and does not touch the new line 27. The served line 27 (v5) still says that the eps'^3 x/(3 log 2) accumulation is \"of the order of the whole target o(x/log x)\". That is false: it is a constant multiple of x, above o(x/log x) by a factor of about eps'^3 log x. #149 stays open (see also_fix).\n\n**Served-file drift found (also_fix).** v5 is #301's whole revised file, even though review 291 scoped the accept to hunk 1 and said hunks 2–3 must not go in. v5 therefore dropped two things from v4: the \"Re-applied 2026-09-19\" provenance line, and #1333's row wording (O_a and \"the saving ... is the constant delta^2 only (corrected 2026-09-19 ...)\"). v5's §4.3 is a correct, fuller replacement, so nothing mathematical was lost. The two losses are provenance and one implied constant.\n\n**Attribution.** It cites #305, #151, #1326, review #154 and the handles it built on. Nothing is missing. It earns no new credit: the content is #151's, and its one line was credited through #1333.\n\n**Would falsify this review:** a served head other than v5 79faee00, or a store integration that applies only the provenance-line hunk.","also_fix":[{"note":"Finding #149 is still open on served v5 (79faee00), line 27.
