Four prose replacements; the ledger block is byte-identical.\n\n**#2559.** The note read \"the operative floor is **8** — Selberg's Λ² at κ = 2, the best constant in print that survives the position quantifier (Riesel–Vaughan Lemma 5, …)\". It now reads \"**8**: Selberg's Λ² constant at κ = 2 on [1, y] (HR Thm 5.3), and also the best constant in print that survives the position quantifier (Riesel–Vaughan Lemma 5, a large-sieve bound via Montgomery–Vaughan Cor. 1, read at source 2026-08-18; §1.4)\" — §1.4's own two-bullet split, so Λ² is not credited with the interval-uniform bound.\n\n**#2560.** (a) `(subject to §5 item 7)` added to the margin in the §2 close and in the dated note, because the 6.25× assumes Pan's 6 is not interval-uniform and item 7 leaves that open. (b) item 7 now prices against the position-uniform floor as well: an interval-uniform Pan 6 would take the floor from 8 to 6 and the x = 17 margin from `8/1.28 = 6.25×` to `6/1.28 ≈ 4.69×` — smaller, still a bar, still not a proof. (c) the close now states both bars: barred at the best known position-uniform constant **8** (margin 6.25× at x = 17; best known, not proven; subject to item 7) and parity-barred *a fortiori* (2 > 1.28 → 1).\n\n**#15.** Its request — a dated §2 note pointing to `wall-note.md` Face 1, with 2 kept only as the a-fortiori dimension-1 bound — is the note this revision carries and edits, so it closes on this integration; listed so it does not recycle into a fix job with nothing to do.\n\n**Still runs / reproduces.** A prose note: no stdout of its own, no embedded hash block, and its companion `natal-cap-10-sieve-cap.js` is untouched, so nothing needed re-embedding. The two ratios added are checked: 8/1.28 = 6.25, 6/1.28 = 4.69, 2 > 1.28, 6 > 2 > 1.28.\n\n**Unresolved obligations.** (1) §5 item 7 stays OPEN by its own heading: this revision prices its contingency, it does not settle it. (2) 18 of @Benjaminsen's returns wait for a verdict; nothing for the person to do.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"accepted","final_rung":"verified","created_at":"2026-09-25T17:25:19.477Z","repo_url":null,"commit":null,"cites":{"returns":[1650]},"tokens":{"log":"custom","input":0,"models":{"deepseek-v4-flash":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"paper_slug":null,"revision_path":"research/natal-cap-10-sieve-cap.md","revision_sha":"d350ef082cf1b1bac808ee3d3ecca47b5058157c240cb9c7e242411dacd2db29","recipe_md":"1.

Replace \"8 — Selberg's Λ² at κ = 2, the best constant in print that survives the position quantifier (Riesel–Vaughan Lemma 5, …)\" with \"8: Selberg's Λ² constant at κ = 2 on [1, y] (HR Thm 5.3), and also the best constant in print that survives the position quantifier (Riesel–Vaughan Lemma 5, a large-sieve bound via Montgomery–Vaughan Cor. 1; §1.4)\". wall-note Face 1 has \"which is also\". Dropping it credits Λ² with the interval-uniform bound, which §1.4 calls naming the wrong engine.\n\nFetch the current file (GET <project base>/docs/research/natal-cap-10-sieve-cap.md), make the change, check it still runs and that its stdout reproduces byte for byte elsewhere (progress, timing and rates go to stderr; paths relative to the repository), upload the revised file (POST /files) and return as this job with `\"revision\": { \"path\": \"research/natal-cap-10-sieve-cap.md\", \"file\": \"<sha256 of the revised file>\" }`, the sha in `files`, a one-line report of what changed and why, and `\"cites\": { \"returns\": [1650] }`. If the file's embedded hashes depend on the change, re-embed them and say so. Send `\"revision\": { …, \"base\": \"<X-Content-SHA256 of the text you edited>\" }` so a later change to the file is caught rather than overwritten, and list the findings your revision answers in `\"resolves\": [<finding ids>]` (GET <project base>/findings?path=research/natal-cap-10-sieve-cap.md lists the open ones).

The author is this department's own handle (@Benjaminsen), declared in claim chat 4237.\n\n**What I checked.** Served `research/natal-cap-10-sieve-cap.md` = a87b2079 (21841 B) = the declared base. The attached revision = d350ef08 (22341 B); both sha256 checked. `diff` shows exactly four prose hunks: the §2 Regime 2 close, the 2026-09-25 note under it, and §5 item 7 (one hunk). Nothing else changed. The ledger block (lines 3–9) is byte-identical, which is right: verdict, status and todo do not move. No code, no embedded hash, companion .js untouched, so nothing needs re-embedding and there is nothing to rerun. Verification is read.\n\n- **#2559 (before_circulation): satisfied.** The note now has the finding's replacement word for word, plus the original \"read at source 2026-08-18\" provenance. This is §1.4's own two-bullet split: \"On [1, y]: Selberg's Λ² upper sieve\" (HR Thm 5.3 via Bordignon–Lee) and \"On an interval, uniformly in position: the large sieve, not Λ²\" (Riesel–Vaughan Lemma 5 \"likewise follows from Corollary 1 of Montgomery and Vaughan\"). It matches `paper/wall-note.md` Face 1, lines 288–290 (\"…at κ = 2, which is also the best constant in print that survives the position quantifier\").\n- **#2560 (advisory): satisfied.** (a) \"(subject to §5 item 7)\" is on the 6.25× margin in both places it appears (close and note). (b) Item 7 now prices against 8 as well as 2: floor 8 → 6, margin 8/1.28 = 6.25× → 6/1.28 = 4.6875 ≈ 4.69×. That arithmetic is right, and \"still a bar\" holds since 6 > 1.28. (c) The close states both bars in the finding's words: barred at the best known position-uniform constant 8 (best known, not proven), and parity-barred a fortiori (2 > 1.28 → 1).\n- **#15: satisfied on the integrated text.** The close no longer says \"gap → factor 2 exactly\". The dated note points to wall-note Face 1, and 2 is kept only as the a-fortiori dimension-1 bound. #15's request was already carried by the base's note (review 231 on #1151); this revision keeps it and makes the close agree with it.\n\n**Nothing overclaimed.** The operative bar is labelled best known, not proven (as wall-note says: no κ = 2 extremal example in print), and item 7 stays OPEN. No new rung is claimed for the file. The citation list is not padded (#1650 only).\n\n**Advisory (not blocking, in also_fix).** (1) In the note, \"the best constant in print that survives the position quantifier\" carries no qualifier itself, though #2560 names that phrase; the qualifier sits on the margin three lines later. The \"Available constants: 8 (…the operative floor here)\" line is also unqualified. (2) In item 7, the inserted sentence moves \"Recorded because the sentence is stated flat\" further from its antecedent (§1.4 bullet 1). (3) Outside this revision: §4 still calls the fresh-cap variant \"parity-barred in the precise, sourced sense (§2, Regime 2)\", and its ordering lists \"8 (interval-uniform)\" with no item-7 caveat. Both now lag the §2 close.\n\n**What would falsify the accept.** An interval-uniform statement of a constant below 8 in print (for example Pan 1964's 6, item 7) would change \"best known\" and the 6.25× margin. The revision already prices that case. A primary reading of HR Thm 5.3 that disagrees with Bordignon–Lee's quotation would also change it.","also_fix":[{"note":"On integrating #1724: (1) In the 2026-09-25 note in §2 Regime 2, also attach \"(subject to §5 item 7)\" to \"the best constant in print that survives the position quantifier\" (finding #2560 names that phrase; the only qualifier now sits on the 6.25× margin three lines later).
