{"id":299,"job_id":663,"problem_id":1,"lane_id":3,"type":"explore","user_id":34,"model":"deepseek-v4.1-flash","provider":"deepseek","report_md":"# Job #663 (explore, lane formalize): prior art for the central object of return #97 — **novel to us**, and the record's own matrix row for it is mislabelled\n\n**Caveat first.** (4.9) is not owned by any source I could reach, and I found no source that\nstates it. The finding is narrower and more useful than that: the record *already carries* the\nnearest printed theorem — BFI II+III's main result, quoted as Theorem A of Maynard I — with the\nright error term and the right accumulation pricing, but the served document records that\ntheorem **without its absolute values** and then generalises the omission in section 4.3. The\nconsequence is that a reader of the note is told no beyond-1/2 absolute-value theorem exists,\nwhen one does and is exactly the shape (4.9) weakens. This return reports that, and files the\ncorrection as an audit.\n\n## Verdict\n\n**Novel to us** — the convention is owned and already named in the record, and (4.9) itself is\nnot in print. Not \"novel\": the source matrix of the served note (`fixed-endpoint-discrepancy.md`\nline 301) already identifies the owner and prices the failure. What is new here is the verbatim\nstatement at its locator (previously unreached primaries, now readable through a quoting paper),\nthe arithmetic that locates the failure in **one term** of that statement, and the correction\nthat the theorem carries absolute values.\n\n## 1. The object\n\nReturn #97 audits `research/fixed-endpoint-discrepancy.md` section 4.3, whose object is (4.9):\nfor the fixed class a = −2, the level excess eps' > 0 and the log power in the range,\n\n    S = sum_{q <= 2x^(1/2+eps')(log x)^(3L), q odd} tau(q)^3 sup_{t <= x} |Delta_q(t; -2)| = o(x/log x).   (4.9)\n\nThe convention it belongs to is the level of distribution of primes in arithmetic progressions\n**beyond the square-root barrier, with absolute values and a single fixed residue class** —\n`SEARCH-CONVENTIONS.md` section 1 row 3 (\"primes in progressions to moduli near and beyond\nx^(1/2) with a Mobius or bilinear weight on the modulus, fixed residue\": owners BFI / Fouvry,\nkeywords well-factorable, convenient-sized factor, Titchmarsh divisor problem). Section 3 of that\nfile records BFI I, BFI III and Fouvry 1985 as unreached primaries, which is why the matrix row\nfor Theorem A is marked \"primaries unreached\".\n\n## 2. What is in print, verbatim, at the page\n\nThe nearest statement is quoted in full in Maynard, *Primes in arithmetic progressions to large\nmoduli I: fixed residue classes*, Mem. AMS **306**(1542), 2025 = arXiv:2006.06572, section 1.1\n(\"Comparison with previous results\"), which states three comparison theorems. Read from the\nauthor's own LaTeX (ar5iv rendering of the arXiv source; the ORA and arXiv PDFs drop the\nstretchy bars in text extraction):\n\n* **Theorem A (Bombieri, Friedlander, Iwaniec; a combination of the main results of BFI II and\n  III, *Math. Ann.* **277** (1987) 361–393).** For a ∈ Z, δ > 0 and Q = x^(1/2+δ),\n\n      sum_{q in [Q,2Q], (q,a)=1} | pi(x;q,a) − pi(x)/phi(q) | <<_a δ^2 x/log x + x(log log x)^O(1)/(log x)^3.\n\n  **Absolute values, all moduli in the dyadic block, fixed residue class, level 1/2 + δ.**\n* **Theorem B (BFI I, *Acta Math.* 156 (1986) 203–251, Theorem 10).** For a well-factorable\n  sequence λ_d of level Q < x^(4/7−ε): sum_{q<=Q,(q,a)=1} λ_q (π(x;q,a) − π(x)/phi(q)) << x/(log x)^A.\n  *No bars*: a signed weighted sum, which is exactly the distinction the record's row blurs.\n* **Theorem C (Zhang; Polymath, arXiv:1402.0811, Theorem 1.1).** δ < 7/300, Q = x^(1/2+δ), moduli\n  with all prime factors ≤ x^η: absolute values, error x/(log x)^A — smooth moduli only.\n\nMaynard I's own Theorem 1.1 is the same object one step further (absolute values, moduli with a\nconvenient-sized factor, up to x^(11/21−ε)); it is already read and priced in the record's matrix.\n\n## 3. Why Theorem A does not supply (4.9): one term, and it is the δ² term\n\n`eh663.py` (uploaded, deterministic, 28 s) does the arithmetic on the quoted error terms:\n\n| question | answer |\n|---|---|\n| which term of Theorem A binds at level excess δ? | the two meet at δ = (log log x)^O(1)/2 / log x; for δ >> 1/log x the **δ² x/log x** term dominates |\n| one block at δ = eps' | δ² x/log x = eps'² · (x/log x) — a **constant multiple of the whole target**, so even a single block at the top of the range fails o(x/log x) |\n| all dyadic blocks, δ ∈ (0, eps'] | the δ² term sums to about **eps'³ x/(3 log 2)** — a constant multiple of x, independent of x; the ratio to the target x/log x is about eps'³ log x, which **grows without bound** |\n| the log-power term alone, accumulated | about eps' x (log log x)^O(1)/(log 2 · (log x)^2) — that **is** o(x/log x) |\n| what the tau(q)^3 weight costs (measured, odd q) | sum_{q<=10^6} tau(q)^3/phi(q) = 7955.57, and the ratio to (log Q)^3 is still rising (1.58, 2.19, 3.02 at 10^4, 10^5, 10^6): the weight costs at least (log x)^3 on the trivial scale |\n\nSo the failure is located in **one term**: a version of Theorem A with the δ² x/log x term\nabsent, or O(1)-uniform in δ ≤ eps', would supply (4.9) once the tau(q)^3 weight and the prefix\nsupremum are handled. The record's matrix row reaches the same conclusion by a different route\n(it prices the same accumulation with the r·b²g weight, \"order eps'^3 x log x (log UV)^2 …\nabove O(x)\") — I am not claiming that part as new.\n\n**Falsifier.** A statement of BFI II/III, Fouvry 1985 or any later paper with the δ² x/log x term\nreplaced by x(log log x)^O(1)/(log x)^3 (or O(1)-uniform in δ), or any source that states (4.9)\ndirectly. If such a statement exists, (4.9) is owned and this report is wrong.\n\n## 4. The correction the record needs (filed as an audit)\n\nThe served note misstates the theorem in two places, and the second generalises the first:\n\n1. **Source matrix, line 301**: \"BFI II + III Theorem A … **no absolute values**, Q=x^(1/2+delta),\n   fixed a: sum_{q~Q}(pi(x;q,a)-pi(x)/phi(q))=O(...)\" — the summand is written without bars and\n   labelled \"no absolute values\". Maynard I's display carries `\\Bigl| … \\Bigr|`; the row's own\n   sibling row for BFI II Theorems 3, 5* correctly says \"absolute values over q~Q in …\", so the\n   matrix does distinguish the two cases elsewhere.\n2. **Section 4.3**: \"the absolute-value theorems stop at x^(1/2) or need a convenient divisor;\n   the beyond-1/2 theorems have no absolute values or need well-factorable weights\". Both clauses\n   are false as written: BFI II+III is an absolute-value, all-moduli theorem at level x^(1/2+δ),\n   and the well-factorable restriction belongs to BFI I Theorem 10 and Maynard II, not to it.\n\nNeither correction changes the note's conclusion — (4.9) is still not supplied by any inspected\nsource — but the *reason* changes, and it changes the search: the missing ingredient is not the\nabsolute value (it is in print, at level 1/2+δ, with a weak saving), it is the size and\nuniformity of the saving in δ. Audit return attached with the revised document\n(sha256 e2ac83d1…, 2 hunks, 25 changed lines, against the served head 21dce4f3…).\n\n## 5. What I could not do (stated, not hidden)\n\n* **The primaries remain unreached**: BFI II (*Math. Ann.* 277 (1987) 361–393) and BFI III are\n  behind Springer; I read their combined statement only as quoted by Maynard I, which is a\n  secondary carrier. The bars are from the author's LaTeX; a reviewer with Springer access should\n  confirm them at the primary before the matrix row is treated as settled.\n* Fouvry 1985 (*J. Reine Angew. Math.* 357, Titchmarsh) was not searched in this pass; the\n  record lists it as unreached and the object there is a different sum.\n* Nothing here is an absence proof: a statement of (4.9) could exist in a source no channel\n  reaches. The claim is about the inspected record and the named owners.\n\n## 6. Rungs\n\n* The verbatim statements of Theorems A/B/C: **read at the page** (arXiv source via ar5iv, plus\n  the ORA and arXiv PDFs for the surrounding text); not a proof.\n* The δ² accumulation, the crossover, and the accumulated log term: **verified** (finite exact\n  arithmetic on the quoted error terms, ranges named; deterministic stdout).\n* The weight cost: **measured** (sieve to 10^6, values printed).\n* \"Not in print\": **no rung** — a clean negative in a named convention, with the three unreached\n  primaries stated.\n\n## 7.
