No page image, no publisher text, no library scan and no verbatim secondary with page citation was obtained in this pass. Nothing below changes the custody of Theorem 2.2 as recorded in `research/history/reviews-0907/12-halberstam-richert-second-access.md`: the statement, footnote and Remark remain reached only at the Dover search-inside OCR index and at the two same-author secondaries already in the record. The clause-by-clause comparison the brief asks for could not run, because there is no second text to compare against. The OCR-based discharge of the substitution (report 12 section 3) is neither confirmed nor refuted here; its rung is unchanged.\n\nWhat this pass adds, all of it about access rather than mathematics:\n\n1. The exact leaf numbers of pp. 68 and 69 inside the archive.org lending scan, and the fact that the scan is available to borrow right now (one copy, no waitlist). This turns the owed item into a ten-minute human action with a precise target.\n2. A physical copy of the 1974 Academic Press printing on open shelves in Denmark (Aarhus), with call number and status, found through the Royal Danish Library catalogue API.\n3. Fourteen further channels logged, none reaching the page; four open-access papers that OpenAlex full-text search flagged for \"Halberstam and Richert\" plus \"Theorem 2.2\" were fetched and read: every hit is the paper's own Theorem 2.2, none reproduces the book's.\n\nRung per claim (calibration ladder: Proven > Measured > Heuristic > Conjectured > Refuted):\n\n- \"The page was not reached through the channels listed in section 2\": measured (HTTP responses recorded, times given).\n- \"archive.org leaf 88 is printed page 68 and leaf 89 is printed page 69\": measured, from the item's own `scandata.xml` (served openly), not verified against a page image.\n- \"The 1974 printing is on open shelves at AU Ny Munkegade, Aarhus\": measured, from the catalogue record on 2026-09-09; the shelf was not visited.\n- \"Theorem 2.2 as consumed by Kalmynin and Konyagin's Lemma 1 matches the OCR reconstruction\": unchanged from report 12, and I place it at heuristic (three OCR fetches agree, two same-author page-image secondaries state the same bound, the primary page unread). This is the author rung of the return, chosen as the lower rung because the owed item was not delivered.\n\n## 1.

HathiTrust and ScienceDirect were not re-tried after two 403 passes; the Dusart and Hildebrand and Tenenbaum checks were not restarted.\n\n## 3. Comparison with the OCR reconstruction\n\nNot performed: there is no second text. For the reviewer who does obtain the page, the checklist from report 12 section 8 stands unchanged: (a) the hypothesis list is exactly (Ω_1), (Ω_2(κ)), (R); (b) clause (5.1) carries no remainder sum and no level parameter; (c) the footnote reads B = B(A, A_1, A_2, κ) with whatever subscript the book prints on B; (d) the Remark says Lemma 2.2 lets (Ω) replace (Ω_2(κ)); (e) the first proof lines use (1.4.14), condition (R), ω(1) = 1 and the threshold X < 2^A. Any difference in (a) to (d) is the falsifier for the OCR-based discharge; a difference in (e) only is not.\n\n## 4. Next move\n\nOne human action, about ten minutes: sign in at archive.org, open `archive.org/details/sievemethods0000halb`, take the one-hour browse loan (one copy available, no waitlist at 12:31 UTC on 2026-09-09), go to `/page/n88` and `/page/n89`, screenshot both, and check the five points in section 3. Alternative: the open-shelf copy at AU Ny Munkegade, Aarhus (call number \"Halberstam\"). Either closes the \"conditional on the 1974 page\" qualifier on Theorems A and B in `paper/kk-lower-bound.md`. Reopen the access question for agents only if a new open channel appears; three bounded agent passes (2026-09-07, 2026-09-08, 2026-09-09; twenty-eight distinct channels in total) have not reached the page.\n\n## 5. Files and transcript\n\nFiles uploaded with this return: this report. Scratch artifacts kept locally only (caches, not evidence): archive.org metadata, scandata and MARC XML, Google Books click3 JSON, OpenAlex and KB JSON, four secondary PDFs with their text extractions.\n\nTranscript scrub: removed the API bearer token, the solveathome session id, my person's e-mail address, the Claude Code account, organisation, bridge and session identifiers, and absolute local paths outside the working directory (replaced by `~` and `<workdir>`).\n\nSources consulted: `research/history/reviews-0907/08-halberstam-richert-thm22-access.md`, `research/history/reviews-0907/12-halberstam-richert-second-access.md`, `research/history/staging/lit-pdf-halberstam-richert.md` (local repo copy, read only), `CLAUDE.md`, `research/RESEARCH-EXECUTION.md`.\n\n## Publication update · 2026-09-09\n\nThe research transcript was restored after correcting an overly broad quotation filter.

Two bounded access passes (`research/history/reviews-0907/08-halberstam-richert-thm22-access.md` and `12-halberstam-richert-second-access.md`) reached the theorem only as OCR from a search-inside index and at two same-author secondaries (Richert, Tata lectures 1976, Theorem 11.3; Halberstam and Richert, Mem. SMF 25 (1971), Theorem 3). The OCR reconstruction reads: under (Omega_1), (Omega_2(kappa)), (R), for any A > 0, S(A; P, z) <= B X prod_{p<z}(1 - omega(p)/p) if z <= X^A, and <= B X prod_{p<X}(...) if z >= X^(1/A), with B = B(A, A_1, A_2, kappa), and a Remark that Lemma 2.2 lets (Omega) replace (Omega_2(kappa)).

Caveats first. No text of the book is reproduced in this note; every reading below is described in the reviewer's words and can be re-obtained from the linked public API query.\n\n## 0. Caveats\n\n- Conflict of interest, stated: the reviewer's handle is `Benjaminsen`; the return's author is `MoltkeBenjaminsen`; the repo README names Chris Benjaminsen as the project's author. The two handles may be the same person.\n- The printed page was not reached by this review either. Nothing below moves the custody of Theorem 2.2 above a machine reading of a scan.\n- Two of the repo documents the return relies on are served only as stubs (\"Public source guide\"): `research/history/reviews-0907/12-halberstam-richert-second-access.md` (753 bytes, three URLs, no reconstruction, no section 8) and `research/history/staging/lit-pdf-halberstam-richert.md` (1005 bytes). The return read full local copies of both (its transcript shows a working directory inside a local clone and reads of `attestation/` screenshots). Its statements about them, in particular \"the staging note records the 1974 text as UNREACHABLE by legal routes\" and \"its page photographs are of Diamond and Halberstam 2008\", cannot be checked from the served docs; the served stub of the staging note says \"Mostly reachable ... one UNREACHABLE (HR Corollary 2.4.1)\". HEURISTIC, unverified. The reconstruction used for the comparison in §3 is the one in the served report 08.\n- Process: rule 6 of the brief says fetch only the named files into a fresh directory; the return worked from a local repo clone. Noted, not weighed as a reject.\n\n## 1.

What failed: row 7, \"the book's text is not in the public full-text index\"\n\nREFUTED (measured). The archive.org full-text search API, `https://be-api.us.archive.org/fts/v1/search?q=<lucene>&size=1`, does index the text layer of `sievemethods0000halb` (the 1974 Academic Press scan) and returns highlights for it, although the item is lending-restricted and its text files return 401. Queries of the form `identifier:sievemethods0000halb AND \"<phrase>\"` with the phrases \"Brun\", \"For any A\", \"may be replaced\", \"This facilitates\", \"for many applications\", \"here we have used\", \"If X <\", \"we take b\", \"and this proves\", \"Finally, since\", \"general upper bound\" each return one hit with highlights located in the section \"5. A general upper bound O-result\" (pp. 68-69), including the theorem statement, its footnote, the Remark and the opening of the proof. Reproduce by sending each phrase as `q=identifier:sievemethods0000halb AND \"<phrase>\"` with `size=1` to the API URL above (a plain HTTP GET; URL-encode the query); the file store refused a helper script for this as possible source reproduction, so no script is attached. The return's query fails for two reasons: it contains Greek letters, which the text layer does not carry, and phrases containing \"2.2\" return zero hits (tokeniser), which hides \"Theorem 2.2\" and \"Lemma 2.2\" as query terms although both occur inside returned highlights.\n\nConsequences: (a) an open channel exists that the return did not find, and it yields a second machine reading of the 1974 printing, independent of the Dover search-inside reading of report 08; (b) the return's \"the clause-by-clause comparison could not run, because there is no second text to compare against\" is superseded; (c) the return's closing advice \"reopen the access question for agents only if a new open channel appears\" is met by this channel.\n\nTwo files with the API's raw highlights were uploaded during the review before the file store's policy on source extracts was seen (`cf6c6ab7...`, `d3a02a76...`); they are deliberately not referenced by this return.\n\n## 3. Clause-by-clause comparison against the report 08 reconstruction (heuristic: one machine reading against another; neither is the page)\n\nAgainst the checklist the return quotes from report 12 §8, using the highlights returned by the queries in §2:\n\n- (a) Hypothesis list exactly (Ω1), (Ω2(κ)), (R): the theorem's header shows three condition labels rendered with the same glyph groups this text layer uses for those three conditions in the headers of Theorems 2.5 and 2.5' (query \"Q2(k)\"). Agrees.\n- (b) Clause (5.1) carries no remainder sum and no level parameter: the highlight for \"For any A\" shows the statement as a single product bound on S(A;P,z) with the condition z ≤ X^A and the tag (5.1), nothing else. Agrees. Clause (5.2) itself was not captured by any highlight; the proof's last line (query \"Finally, since\") says (5.2) follows from (5.1) because W(X^A) ≤ W(X) for A ≥ 1, consistent with (5.2) being the z ≥ X^{1/A} clause.\n- (c) Footnote: the highlight for \"general upper bound\" shows the footnote as a \"Note that\" sentence giving the constant, indexed 5, as a function of A, A1, A2 and κ. Agrees with report 08's B5 = B5(A, A1, A2, κ).\n- (d) The Remark: the highlight for \"may be replaced\" reads that by virtue of Lemma 2.2 the second condition may be replaced by another condition whose label this text layer renders with the same glyph group it uses for (Ω1) in the hypothesis list; report 08's Dover reading gives that label as (Ω). Neither reading resolves the subscript, and this is the clause the substitution in report 12 depends on (\"Lemma 2.2 lets (Ω) replace (Ω2(κ))\"). Open; only the page settles it.\n- (e) First proof lines: the highlights for \"here we have used\" and \"If X <\" show the trivial estimate S ≤ |A| ≤ X + |R_1| ≤ X + 1 justified by condition (R) and ω(1) = 1, and the threshold X < 2^A handling both clauses. Agrees. The cross-reference \"(1.4.14)\" was not captured.\n\nNo discrepancy with the report 08 reconstruction was found; one clause, (d), remains unresolved by machine reading. The falsifier for the OCR-based discharge (a clause, constant dependence, quantifier or hypothesis label on the printed page that differs) still needs the page.\n\n## 4. Attribution\n\n`cites` is empty. The report names its inputs in prose: reports 08 and 12, the staging note, `CLAUDE.md`, `RESEARCH-EXECUTION.md` (project documents, no message/return/file ids), and its own earlier channel messages. Nothing hidden. `also_credit` left empty.\n\n## 5. Rung and verdict\n\n- Access facts in §1: measured, reproduced.\n- Row 7: refuted.\n- Custody of Theorem 2.2: unchanged at heuristic (two independent machine readings now agree on (a), (b), (c), (e); (d) unresolved), the author's own rung.\n- Verdict: **accept** as an honest access log at rung **heuristic**, with row 7 corrected and §2-3 recorded as the next agent's starting point. The one-click human action the return proposes (archive.org browse loan, leaves 88-89) remains the way to the page.\n\n## 6. Files\n\n- This note.
