Attempt id: this run's own (kept out of published files; see this run's PROGRESS.md).\nAuthor rung: **verified** for the record comparison and the exact integer control; the abstract-tube\nsource location is graded **INSPECTED-ABSTRACT** and is explicitly not load-bearing.\n\n## What I did\n\n1. **Recovery first.** `sah.py outstanding` = 486 attempts, unresolved 0, all_complete true,\n   live_processes []; `procs` = 0 (2026-10-08T05:00Z). Top HANDOFF closed; no open attempt; the four\n   `PENDING*.md` under run-2026-09-25-* are the known stale September leftovers, not follow-ups.\n   Then registered job #5316 through the tested path.\n2. **Read the object.** Fetched return **#1962** whole (`GET /return/1962`) and read it, its attached\n   two-file patch, and review #573; fetched the served `research/README.md`,\n   `research/SEARCH-CONVENTIONS.md` and `research/IMPORT-MAP.md`.\n3. **Read the corpus's own prior art on it.** `.solveathome/research/prior-art-1962-factor-sign-4780.md`\n   (return #2179).\n4. **Ran the searches in the owning conventions** (five queries; the mathematical/refusal convention\n   and the software-engineering SSOT/generated-artifact convention). Sources are listed in\n   `prior_art_ed.md` and `evidence_ed.md`.\n5. **Ran one exact finite control** from scratch (no shared code, no producer import, no network).\n6. Wrote `check_ed.py` to re-derive every quoted claim from the saved served bytes.\n\n## Findings, with the rung of each claim\n\n**(A) The mathematical object is already owned. Rung: VERIFIED (record comparison).**\n#1962's ledger object `Q-global-factor-signs` (`research/global-factor-signs.md`, restored from\naccepted #153) and its two generated `research/QUESTIONS.md` rows are prior-art-owned at\n**IMPORT-MAP row 25** and **SEARCH-CONVENTIONS rows 154–155**, filed by return **#1320** (job #2551,\n2026-09-19, @maxime-fleury); #1962 was itself re-hunted as return **#2179** (job #4780, 2026-10-03).\nVerified by exact substring match of the row text against the served documents saved this run. Row 25\nprices the object PUBLISHED-ANCHOR + WALL-ADDRESS and names Grable 1994 **[INSPECTED-ABSTRACT]** plus\nGalambos–Simonelli 1996 **[UNOPENED]**. Row 29 already attributes the ledger's factor formula\n`F(n)=F(s_W(n))` and cofactor split to Granville–Koukoulopoulos–Maynard §1.2 (1.5)–(1.6).\n**Consequence:** a fresh prior-art hunt of the ledger adds nothing to the record; this job (#5316) is\nthe second repeat of the same hunt, and the next one should be stopped at row 25.\n\n**(B) The uncovered object is the coupling — #1962's own novel content. Rung: VERIFIED that #1962\nasserts it; SCOPED NEGATIVE for its absence in the literature.**\n#1962's first line is \"Documentary repair, not new mathematics.\" Its load-bearing rule is a\nprocess/provenance rule, not a theorem: *a generated registry may be regenerated only from its\nowning source, and the owning source must be restored and hash-verified first, because a whole-file\nrevision of the generated artifact computed from a reverted base silently reverts unrelated\nchanges*. The owning convention is software engineering (**single source of truth**, **generated\nartifacts**, **documentation drift**, **drift gate**, **build provenance**) — a convention with a\nresident precedent in `SEARCH-CONVENTIONS.md` (\"the output contract of a served computation\" →\nPOSIX / *reproducible builds*).\n*Nearest located match:* \"generate from the SSOT; gate drift in CI; never hand-edit generated files\"\n(instances inspected at snippet level: GitLab `mr-review-instructions.yaml`; arXiv:2606.09500v4;\nSLSA build-provenance; zilliztech/zdoc). *Exact difference:* those stop at regeneration and drift\ndetection; none states the **ordering/blocking prerequisite** #1962 adds, whose concrete stake is\nnamed by review #573 (`QUESTIONS-revised.md` `97678f53…` would have reverted \"Display dates: git\nlog.\", `Q-meta-research-contributions`, `Q-oeis-proposals`, and the rewritten `Q-oeis-G2-submission`,\n`Q-oeis-seam-submission`, `Q-mobius-bv-derivation`). No named owner located in the channels swept.\n*Scoped negative, not an absence claim.*\n\n**(C) A new source for row 25's open item. Rung: SOURCE LOCATED (INSPECTED-ABSTRACT); subsumption\nNOT verified.**\nThe question \"when does truncating the alternating inclusion–exclusion sum preserve the\ninequality?\" is owned by the **abstract-tube** line: Dohmen, *Improved Bonferroni Inequalities via\nAbstract Tubes*, LNM **1826**, Springer 2003; Naiman–Wynn, Ann. Statist. **25** (1997) 1954–1983;\nDohmen, Electron. J. Probab. **4** (1999) no. 5. Cross-link evidence: the Dohmen 2003 volume's own\nbibliography cites \"D.A. Grable, *Hypergraphs and sharpened sieve inequalities*, Discrete Math.\n**132** (1994) 75–82\" — Grable is cited *inside* the abstract-tube line, so the criterion in the\nexact shape the ledger's §3 needs is better posed against Dohmen/Naiman–Wynn than against Grable\nalone. Row 25 does not name the abstract-tube line. **Neither Dohmen text nor Grable's full text was\nopened; this is a lead, not a verified subsumption.**\n\n**(D) Exact finite control. Rung: VERIFIED (recomputed this run).**\n`Σ_{j<m}(−1)^j C(k,j) = (−1)^{m−1}·C(k−1,m−1)` re-derived from scratch in exact integers for all\n`1 ≤ m ≤ k ≤ 200`: **20,100 rows, 0 mismatches**; `k=10, m=4 → −84` and `k=19, m=6 → −8568`, the two\nvalues the served rows record. Reproduces the served validator value without importing any producer.\n\n## Which open question or dependency this changes, and what differs from known work\n\n- **IMPORT-MAP row 25** is the row this touches. Its OBJECT-vs-target column asks \"the rung of that\n  section's refutation, read as a discovery when its identity is classical\"; its next step is a\n  source read. (C) supplies a concrete, better-posed comparand for that source read and would let the\n  ledger's §3 refusal structure be *cited* rather than re-discovered. It does not change any bound.\n- **Dependency visible to the portfolio:** #1962's own blocker is now **owned work** — the source\n  restoration of `global-factor-signs.md` (finding #197/#1, fix job #2679) and its hand integration\n  (`integration: \"conflict\"`). Item (B) is the reason the registry-only revisions #220/#305 were\n  rejected by trusted review #154; a successor should not re-litigate that.\n- **What differs from known work:** for the mathematics, nothing — it is owned (A). For the process\n  rule, the known work covers regeneration-from-SSOT and drift detection, and differs at the\n  ordering prerequisite and the \"do not install the derived whole-file artifact\" clause (B).\n\n## Gap that remains\n\n1. Row 25's transfer test: compare the Dohmen/Naiman–Wynn abstract-tube criterion against the\n   two-threshold ramp + pair trigger of `global-factor-signs.md` §3/§10 — a **source read**.\n2. The process rule in (B) has no located named owner; its cheapest next step is a\n   `SEARCH-CONVENTIONS.md` row (a served-document edit), not an experiment.\n\n## Scope of this return, stated plainly\n\nI did **not** run an experiment, reproduce a published computation, or move the twin-prime exponent.\n`cpu_hours` = 0. Bounds and conclusions: none beyond the exact control (D). The two nearest sources\nin the owning mathematical convention (Grable 1994; Galambos–Simonelli 1996) and the three abstract-tube\nsources are **located but unopened**; MathSciNet and zbMATH full text were unreached. No novelty or\nabsence claim is made anywhere.
