{"id":1057,"job_id":1981,"problem_id":1,"lane_id":2,"type":"explore","user_id":17,"model":"claude-fable-5-1","provider":"anthropic","report_md":"# Job #1981 (prior art for return #161): the adjacency criterion behind L(T_x, p) is Holt's same-image fusion lemma (one-class form), already on the corpus's convention row; the run statistic and its table have no match in the stated search; one small bound ties #161's first-1 primes to the G2 ladder\n\n**Outcome: partial known match, exact difference stated, no match for the object itself; no IMPORT-MAP row and no audit.** #161 (@zemaj, measure, verified) tabulates L(T_x, p), the longest run of consecutive twin-admissible slots of one x#-period whose residues mod p lie in a 2-set {a, a+2} (the corpus's `runFor`, free translate a), for tiles T5..T29 and primes p ≤ 1009 (1307 entries). Owning convention, per SEARCH-CONVENTIONS.md row 87 (already there): \"two slots killed at the same fold, adjacent in the gap word\" = Holt's \"fusions at γ_i and γ_j occur in the same image of s iff p divides the span\" (arXiv:2502.20470v3, \"Eratosthenes sieve supports the k-tuple conjecture\", §3 Lemma 2, printed p. 5; v3 July 8 2025), with the one-class span form in Holt–Rudd arXiv:1408.6002 p. 11 (\"closures\"), and a second occurrence in Holt arXiv:2605.19165v1 §3. I read Lemma 2 and its neighbourhood in the text layer: \"In step R3 of creating G(p#), the fusions at γ_i and γ_j occur in the same image of s iff p divides the span [between them]\", proof from \"the fusion at γ occurs when γ mod p = 0\"; the accompanying remark \"for s = 2, 10, 2, 10, 2 and p ≥ 17, |s| < 2p so all fusions occur in separate images\", and Lemma 3's multiplicity ν_p(s) = number of residue classes mod p covered by an instance of s, 1 ≤ ν_p(s) ≤ min{p, J+1}, with the dichotomy at p > J + 1 via Q(s), the product of odd primes dividing a span between boundary fusions.\n\n## 1. Exact difference\n\nHolt's statement is the one-class (Eratosthenes) case: a prime p kills two positions of a constellation in the same image iff p divides their span. The twin word kills two classes, {0, −2} mod p, so two adjacent twin slots are killed at the same phase iff their span is ≡ 0 or ±2 (mod p): the corpus's okPair (Lgrowth.js, U-FRAME §5), and the three-integer seam criterion of #1052 is the same lemma applied to the wrap pair. So the criterion underlying L is owned (Holt; Holt–Rudd), in the one-class form, and its two-class form is an immediate extension that the corpus states and uses but that is not printed in these sources as such. The object #161 tabulates is different from anything in Holt: L is the maximum over all phases of the longest run of consecutive slots of the full period that one prime kills at one phase; Holt tracks fixed constellations s (length J, span |s|) and asks how many of their boundary fusions fall in one image (ν_p(s)), which is a per-constellation multiplicity, not a maximum over the period. His threshold remark, |s| < 2p ⇒ all fusions in separate images, is the one-class ancestor of the bound in §2 below.\n\nThe longest-run object over one given periodic word is, as SEARCH-CONVENTIONS row 99 records, posed nowhere; the longest-run literature (Vaggelatou 2003; Fu–Wang–Lou 2003; Eryilmaz 2006) owns the random-word laws only. The Jacobsthal-computation literature (Hagedorn 2009; Ziller–Morack arXiv:1611.03310, primes to 251; the paired progressions note arXiv:1706.03668, primes to 73) sieves prime by prime and tracks covered runs, so a \"most consecutive survivors one prime removes\" quantity is an unnamed intermediate of those algorithms, but no such statistic is defined or tabulated in the abstracts (bodies not read at the page). No verbatim match for L(T_x, p) or its table was found within this search; no match found is not established novelty.\n\n## 2. A bound the criterion gives for free, checked against #161's first-1 column\n\nIf p > G2(x#) + 2, no adjacent gap g of the twin word satisfies g ≡ 0 or ±2 (mod p) (0 < g ≤ G2 < p and g = p − 2 would need p ≤ g + 2), so no two adjacent slots are jointly killable and L(T_x, p) = 1. Hence the first prime with L = 1 in each column of #161 is at most the least prime exceeding G2(x#) + 2:\n\n| x | G2(x#) (exact ladder) | L = 1 guaranteed for p > | first p with L = 1 (#161) |\n|---|---|---|---|\n| 5 | 12 | 14 | 11 |\n| 7 | 30 | 32 | 11 |\n| 11 | 42 | 44 | 23 |\n| 13 | 66 | 68 | 37 |\n| 17 | 108 | 110 | 59 |\n| 19 | 150 | 152 | 71 |\n| 23 | 204 | 206 | 107 |\n| 29 | 258 | 260 | 127 |\n\nEvery measured first-1 prime respects the bound, and sits at roughly half of it, because the bound needs only that SOME gap be ≡ 0, ±2 (mod p) while a run needs it at an actual adjacent pair position with the right phase; the large gaps (near G2) are rare. PROVEN (two lines) and MEASURED consistent; it also gives \"every column reads 1 from p = 127 on\" a proof for p ≥ 263 (G2(29#) + 5) and leaves the observed 127..261 stretch to the data. This bound is the twin-word transposition of Holt's half-span threshold, which row 87 already records (\"the two thresholds J+1 and |s|/2, past which all fusions of adjacent gaps must occur in separate images\"; in arXiv:2605.19165v1 §3, p. 11, for his constellation of span 3242: \"for q > 1621 all of the fusions between adjacent gaps occur in separate images\"), with the twin word's ±2 shifting the threshold from half the span to G2 + 2 and the constellation replaced by the whole period; it is recorded here because #161 states the first-1 primes as observations and the ladder supplies their ceiling.\n\n## 3. Rungs, sources, what remains\n\nRungs: the convention identification is a sourced match at the level of the printed lemma (text layer of the PDF read; the page image not rendered here); the exact difference (one-class versus two-class kill, per-constellation multiplicity versus period maximum) DERIVED; the G2 + 2 bound PROVEN; the table comparison MEASURED from #161's stated values and the exact ladder (research/exact-g2-ladder.js as quoted in attack-bonferroni-degree.js). Sources inspected: Holt arXiv:2502.20470v3 (text layer, §3 around Lemma 2 and Lemma 3), Holt arXiv:2605.19165v1 (text layer, §3 fusion lines), abstracts of Ziller–Morack arXiv:1611.03310 and arXiv:1706.03668, SEARCH-CONVENTIONS rows 87 and 99, PRIOR-ART.md (no L row beyond the conventions), #161, #1052, #1024, #690, #645.

No IMPORT-MAP row: the object is a definition plus a table, not an imported result, and its criterion is already attributed on row 87. No audit: row 87's locator (§3 Lemma 2, p. 5) matches the text. Remaining gap: none for attribution; the table itself (1307 entries) has no published counterpart to compare with, which is #161's scope statement too.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-09-18T18:04:41.382Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":["zemaj","Benjaminsen"],"returns":[161,1052,1024,690,645],"messages":[]},"tokens":{"log":"claude-code","input":128,"models":{"claude-fable-5-1":13779},"output":13779,"source":"claude-jsonl","entries":4,"cache_read":2630527,"cache_write":15026,"observed_models":["claude-fable-5-1"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Check\n\n1.
