{"id":3182,"job_id":4737,"problem_id":1,"lane_id":null,"type":"audit","user_id":1,"model":"claude-opus-5-5","provider":"anthropic","report_md":"# research/history/staging/recon-0904-sifting-limit-floor.md: close #156 (hunk already installed) and apply advisory #19199\n\n**Change: five literal edits. The verdict line and PARTIAL are unchanged.** Served `7b37dac9…` (43873 B) becomes `67ad9268…` (43892 B). The patch is attached.\n\n## Repair delta\n- **Finding #156:** \"Apply the matching source-verdict-only hunk in registry-712.patch … Revised complete source file SHA-256 e10ee5ef…. Historical body and PARTIAL status preserved.\"\n- **Sources:** return #321 (registry-712.patch `98b79bc6…`, hunk `@@ -7,3 +7,3 @@`, revised source `e10ee5ef…`); return #1679 (accepted at verified, resolves [158], revision `cba66f96…`); return #2083 (accepted at verified, revision `7b37dac9…`, review 607); the owning note research/history/staging/redteam-0904-sifting-limit.md (`e93d7134…`), lines 170–181 and 576–580.\n- **Prior attempt:** #1679 installed #321's hunk text and listed only #158 in `resolves`, so #156 stayed open. #2083 then refined the same line 8 with the epistemic wording (\"not known\"), and review 607 accepted it.\n- **Finding #156, current state:** #321's `+` hunk text occurs verbatim as a substring of served line 8. The served line also has #2083's accepted refinement, which is why `e10ee5ef…` cannot be restored byte-for-byte without reverting accepted work. The obligation in #156 is therefore already met, the historical body is intact, and PARTIAL is unchanged. This return records that and closes #156.\n- **What changed (advisory #19199, review 607):**\n  1. l.164–165: \"no `κ > 1` example exists while `κ > 1` lower bounds do\" → \"no `κ > 1` example is known while `κ > 1` lower bounds are in print\" (the wording #19199 quotes).\n  2. l.194, l.490 and the source table at l.543: Halberstam, *Bull. AMS* **40** (2003) p. 116 → **p. 117**. Redteam lines 170–181: \"The sentence is on **p. 117** … Page 116 is PDF page 8 and does not contain it. [VERIFIED]\". The rider at l.25 of this same file already says \"Halberstam is p. 117, not 116\".\n  3. l.487 (vocabulary table): \"which at `κ > 1` does not exist\" → \"is not known to exist\". This is the same over-strong claim as edit 1. The owning redteam note's item 7 (l.580) asks for exactly this clause to be struck, since Halberstam says \"not known\".\n- **Success test:** `grep -c 'p\\. 116'` gives 0 (it was 3). \"example exists\" and \"does not exist\" no longer appear. Line 8 is byte-identical to the served file. The diff has exactly 4 hunks and 5 changed lines, with no other bytes changed.\n\n## Preservation checks\n| Result | Baseline → candidate | Check | Evidence | Status |\n|---|---|---|---|---|\n| Verdict line 8 (#321 hunk + #2083 refinement), PARTIAL | unchanged | diff: no hunk before l.164 | attached patch | preserved |\n| Brady Theorem 22 / Corollary 3 reduction, all numerics | unchanged | diff touches prose only, no numbers except the page cite | patch | preserved |\n| Halberstam quotation text | unchanged | only the page number changes; quote is byte-identical | l.196–197 | preserved |\n| Absence of extremal examples at κ>1 | \"does not exist\" → \"not known\" | weakened to the cited source's scope | Halberstam p. 117; redteam l.170–181, 580 | corrected |\n\nNot resolved here: nothing else is open on this path in findings.json apart from #156 and #19199.\n\nCalibration: VERIFIED as an editorial and citation repair. No mathematical claim is added or strengthened.
