What was searched, per channel (all this session, 2026-10-20/21)\n\nEvery channel below was calibrated in-session where the conventions require it;\n\"hit\" counts are observed outcomes.\n\n1. **arXiv API** (`export.arxiv.org/api/query`; calibration control\n   `all:\"twin primes\"` → 255 results, recorded precedent 252 — channel live):\n   - `cat:math.NT AND abs:\"discrepancy\" AND abs:\"twin\"` → **0**.\n   - `abs:\"discrepancy\" AND abs:\"primorial\"` → **0**.\n   - `abs:\"Erdos-Turan\" AND abs:\"sieve\"` → **0**.\n   - `abs:\"sawtooth\" AND abs:\"sieve\"` → **0**.\n   - `abs:\"rough numbers\" AND abs:\"discrepancy\"` → **0**.\n   - `abs:\"sifted\" AND abs:\"discrepancy\"` → 3, all irrelevant (quantum key\n     distribution, LLM product descriptions, LLM tool-use evaluation).\n   - `abs:\"Jacobsthal\"` → 117; with `abs:\"twin\"` → exactly 1: Ziller–Morack\n     1706.00317 (owned, §4 below); `abs:\"Jacobsthal\" AND abs:\"residue\n     classes\"` → 0.\n   - `au:\"Holt\" AND cat:math.NT` → 22 works; Fred B. Holt's complete arXiv\n     list scanned. Newer than the corpus's 2026-08-18 sweep: 2603.25896\n     (nonconvex constellations I), 2603.25915 (surviving sieve I), 2605.19165\n     (nonconvex constellations II), 2608.26384v4 (discrete dynamics — corpus\n     checked v3 at abstract level). **2603.25915 read in full this session:\n     0 occurrences of \"twin\", no two-class or count-discrepancy content** (it\n     is about gap/constellation populations and Legendre's conjecture). The\n     others checked at abstract level; none is the two-class discrepancy sup.\n2. **OpenAlex** (direct API, reached):\n   - `cites:W4385890017` (Holt 2308.07570) → **0 citing works** — no indexed\n     successor extends the one-class discrepancy sup, so no two-class\n     extension arrives through that citation graph. (A floor, not a proof:\n     OpenAlex coverage is incomplete.)\n   - full-text search `twin primorial discrepancy` → 5 works, all inspected:\n     \"Replication–Deletion Primorial Sieve\" (Zenodo 10.5281/zenodo.18441735,\n     2026 — builds the same twin-admissible comb stage-by-stage and claims an\n     unconditional twin-prime theorem; **no discrepancy sup, unrefereed\n     deposit**), RAPF series (Zenodo 10.5281/zenodo.20602688 — mod-6 lattice\n     Fisher information; not our object), a moments/decomposition note\n     (10.55640/ijmse-04-01-01, unrelated), \"Prime Curvature Geometry\"\n     (F1000 10.32388/fma6aw — remainder-envelope hypothesis framework, no\n     comb sup, unrefereed), and a lexicon.

Known match, closest published result, exact differences\n\n### 3.1 The one-class discrepancy sup — Holt, arXiv:2308.07570v5 (read in full)\n\n**Known match at the family level; the closest published statement to the\nnote's sup object.** Fred B. Holt, *On the counts of p-rough numbers*\n(arXiv:2308.07570; v5 dated 12 Feb 2024; arXiv comment \"17 pages, 9 figures\",\nwhile the v5 PDF itself carries 10 numbered figure captions; math.NT; no\njournal ref). Object: Φ(x,p) = count of p-rough numbers ≤ x and\nΔΦ(x,p) = Φ(x,p) − (φ(p#)/p#)·x, the signed discrepancy of the ONE-CLASS comb\n(one residue class per prime, the survivors of Eratosthenes sieve at level p).\n\nPublished content, read at the PDF this session:\n- Theorem 3.1 (p. 10): ΔΦ(x,p) is bounded and periodic with period p#, with\n  max_x ΔΦ = max_{p≤x≤p#} ΔΦ = lim sup_{x→∞} ΔΦ (translational symmetry) and\n  min_x ΔΦ = −max_x ΔΦ.\n- Rotational symmetry (abstract and §2, pp. 1–3): ΔΦ(x̃_k + x, p) =\n  −ΔΦ(x̃_k − x, p) around the midpoints x̃_k = (k−½)p#/2.\n- Table 2 (p. 14): exact max&min|ΔΦ| for p = 5, 7, 11, 13, 17, 19, 23, 29 —\n  ±0.9333, ±1.5143, ±2.5195, ±3.5475, ±5.4388, ±8.6592, ±14.4180, ±20.9128,\n  with the mean gap µ and rising-zero counts. (The corpus's PRIOR-ART.md row\n  reproduces this table; re-checked against the primary source here — no\n  discrepancy.)\n\n**Exact differences from return #4334's object** (all verified):\n1. **Classes.** Holt's comb carries ONE class per prime (p-rough numbers).\n   The note's comb carries TWO coupled classes per prime (r ≡ 0 and r ≡ −2;\n   divisor pairs with gcd(d₁,d₂) | 2). The corpus proves the identification\n   in one direction only: Holt's max|ΔΦ| is the sup of the k = 1 case of the\n   same discrepancy family whose k = 2 signed sup the corpus measures\n   (`discrepancy-two-class.md` §5). No published k = 2 analogue exists in any\n   channel searched.\n2. **Function.** Holt's object is the plain count deviation. The note's\n   ρ̃ is the Rosser–Iwaniec WEIGHTED sawtooth potential\n   ρ(y) = Σ_j w_j ψ((y−c_j)/q_j) with signed block weights — a different\n   weight family on the same lattice, the certificate-side object\n   (T(x) = H·M + R_H(x)).\n3. **Symmetry.** Holt's rotational symmetry is around the midpoints of the\n   one-class cycle. The note's PROVEN reflection ρ̃(W−3−y) = −ρ̃(y) is the\n   two-class class-swap involution y ↦ −y−2 (it swaps r ≡ 0 and r ≡ −2 and\n   needs ψ(−t) = −ψ(t) − 1 at integers). Same mechanism family, different\n   class system, different function, different center; the two-class plain\n   count's mirror r ↦ W−2−r (and its exact max+min = −(1−2δ₂) consequence)\n   is the corpus's own observation (`discrepancy-two-class.md` §2), not\n   Holt's.\n4. **Coverage.** Holt's Table 2 stops at p = 29 and is one-class. The note's\n   two-class suprema (28.122062 at z=31, 52.219092 at z=37, ≥70.651250 at\n   z=41) and the first walked sup|R_H| values have no published counterpart\n   in any channel searched.\n5. **Question.** Holt bounds and tabulates the sup (largeness, exact finite\n   values). The note's asymptotic question is a SMALLNESS law (RML(α) with\n   α < β₂ = 4.26645; REC's sup ≤ z^{u₀/2−ε}·rms) — an upper-bound\n   concentration statement, the opposite direction.\n\n### 3.2 Oscillation theorems for sifting functions — FGHM 1991 (inaccessible; characterized from citation contexts only)\n\nFriedlander, Granville, Hildebrand, Maier, *Oscillation theorems for primes in\narithmetic progressions and for sifting functions*, J. Amer. Math. Soc. 4\n(1991), no. 1, 25–86 (DOI 10.1090/S0894-0347-1991-1086965-9). **Not accessed**\n(AMS full text HTTP 403; no open copy located; Semantic Scholar rate-limited).\nFrom citation contexts (Holt's own bibliography item 5, which connects the\nlargest gaps of G(p#) to \"the Problem of Jacobsthal\"; the numdam \"Limitations\nIII\" referencing; survey usage): the paper proves Ω-type oscillation results —\nthat errors of sifting functions (counts of integers free of small prime\nfactors, in progressions and short intervals) exceed their expected\napproximation scales in asymptotic regimes, in the Maier-matrix tradition.\n[INFERENCE — from citation contexts; the paper was not read.]\n\nExact differences (at the level citable without the paper): asymptotic\nΩ-largeness in x, not exact finite-period suprema; one-class sifting\nfunctions, not the two-class twin comb; no table of suprema like Holt's\nTable 2; no smallness law of REC/RML type. What it could change if read: it is\nthe strongest published statement family on the LARGENESS side of\nsifting-function errors, so it is the natural candidate anchor for the\nadversary/lower-bound side of RML (the corpus's `two-class-lower-bounds.md`\ndirection) and an IMPORT-MAP lead — **flagged as an unverified lead only**,\nsince the load-bearing statements were not read this session.\n\n### 3.3 The two-class GAP channel — Ziller–Morack (owned by the corpus; re-verified at source)\n\nM. Ziller, J. F. Morack, *Divisibility in paired progressions, Goldbach's\nconjecture, and the infinitude of prime pairs*, arXiv:1706.00317v1 (1 Jun\n2017, unpublished preprint; Companion computation note arXiv:1706.03668;\nOEIS A288815/A072753). Defines the paired Jacobsthal function j₂(n) (every\npaired progression ⟨a,b⟩_m with even difference contains a pair coprime to n)\nand h₂(n) = j₂(p_n#); conjectures h₂(k) < p_k² − p_k and proves the\nsufficiency of that bound for Goldbach/twins. Re-read at the PDF this\nsession; ownership confirmed: `covering-dive.md` §2.1 already carries the\nfull lineage, the isolation (one self-citation; no refereed version) and the\n\"no published upper bound at any exponent\" negative with its three\nqualification passes. **Different channel from the note's object**: the GAP\nfunction vs the discrepancy sup; the corpus itself warns the two channels\nhave different prices (exponential-in-π(x) vs power-of-log;\n`discrepancy-two-class.md` §7) and that no number should be carried between\nthem.\n\n### 3.4 What was NOT found (bounded negative, per channel)\n\nWithin the channels and queries of §2: **no published computation, table,\nbound or asymptotic for the two-class twin-comb interval discrepancy sup —\nneither the plain count ΔΦ₂, nor the weighted potential sup|ρ̃_z|, nor the\nwindowed sup|R_H| at primorial-related lags — and no published trace of the\nexact values 28.122062, 52.219092, 70.651250, 64.416936, 97.905636, of the\nRML slope law, or of REC(s,u₀).** This is a bounded negative over named\nchannels with in-session calibration; it does not establish absence\n(SEARCH-CONVENTIONS rule). The corpus's own parallel gap stands: its\n`discrepancy-two-class.md` forbade calling the interval analogue absent until\nan owning-convention search ran — this report supplies that bounded pass and\nkeeps the same discipline.\n\n## 4. Rungs, per claim\n\n| claim | rung | basis |\n|---|---|---|\n| Holt 2308.07570v5 is one-class only (no twin/two-class content anywhere in the text) | measured | full PDF text read; 0 grep hits for twin/two-class/n+2 |\n| Holt's Theorem 3.1, rotational symmetry and Table 2 values as quoted | measured | read at the PDF (pp. 1–3, 10, 14); table cross-checked against the corpus's PRIOR-ART row — agreement |\n| The exact differences 1–5 of §3.1 | proven (as statements about the two sources' text) | both sources read in full this session; the k=1/k=2 family identification is the corpus's own proven result, cited not re-proven |\n| FGHM 1991's content as characterized in §3.2 | heuristic | citation contexts only; paper inaccessible (403) — marked [INFERENCE] in the text |\n| Ziller–Morack content as described | measured | PDF re-read this session; corpus ownership cross-checked |\n| No published two-class discrepancy sup / no trace of the exact values, within the named channels | measured (bounded negative) | per-channel outcomes in §2, each with its calibration or failure record |\n| Novelty of the note's exact suprema beyond the searched channels | NOT claimed | absence not established; FGHM, the Holt 2022 book and MathSciNet/zbMATH review text remain unread |\n\n## 5. Inaccessible sources, recorded\n\n- FGHM, JAMS 4 (1991) 25–86: AMS PDF HTTP 403 (both landing-page and direct\n  PDF paths); no open-access copy via Granville's page (lists without PDF),\n  arXiv, OpenAlex or numdam (numdam carries only citing works);\n  Semantic Scholar API HTTP 429 twice.\n- Holt, *Patterns among the Primes: a study of Eratosthenes sieve* (KDP, June\n  2022; Amazon 9798831607314): self-published; no retrievable TOC or preview\n  text this session; remains the corpus's flagged uncovered item. It is the\n  single most plausible place a two-class comb treatment could hide, given the\n  author's program; a full-text read could change §3.4 and is the first\n  recommended follow-up.\n- MathSciNet review text and zbMATH Open: not exercised this session (see\n  §2.6); the corpus's 2026-08-18 zbMATH triage stands for the Jacobsthal\n  channel.\n- Semantic Scholar citation graph for 1706.00317: not re-run (rate-limited);\n  the corpus's 2026-08-18 isolation (one self-citation) stands.\n\n## 6. The gap that remains, and the cheapest decisive next checks\n\n1. **Read FGHM 1991** (library/print or a licensed copy): pin its\n   sifting-function theorems exactly, then re-grade §3.2 from [INFERENCE] to\n   measured, and price it as an IMPORT-MAP lead for the LARGENESS side of\n   RML (the adversary direction), where an Ω-theorem for one-class sifting\n   errors is the closest published analogue of a two-class lower-bound law.\n2. **Read the Holt 2022 book** (buy/borrow; the corpus's standing\n   instruction): specifically its chapter set around the ΔΦ machinery — the\n   only plausibly owned location for a two-class comb discrepancy treatment.\n3. **The unrefereed deposits** (Zenodo 18441735; F1000 PCGH): no action\n   required; recorded so a future wave does not mistake their existence for\n   literature coverage of the sup.\n\n## 7. Operational limits of this run\n\n- The brief's chat step (\"read the lane chat\"; \"claim once (500 chars) in the\n  task's channel\") could not be executed through reviewed tooling: the helper\n  exposes the channel index (read this session: 9 channels; `formalize`\n  active, last activity 2026-10-20T15:33Z) but has no route for message\n  bodies and no post command; improvising raw API calls is outside the\n  reviewed tooling contract.
