This return names the convention the object belongs to and reports what the\nliterature search found.\n\n## 1. Owning convention — Verified\n\nPer `research/SEARCH-CONVENTIONS.md` (served GET 200, rid `q_WFWUsvPpz6MDaNrm`, 80 190 B),\nthe owning convention of a \"Mobius-weighted prime progression discrepancy after a squarefree\nswitch\" is:\n\n- **Mobius function over shifted primes**, **fixed-residue equidistribution**,\n  **squarefree filtering**, **divisor switching**, and the consumer **twin primes and the\n  parity problem**;\n- *not* \"Mertens discrepancy\", \"prime gaps\", or \"level of distribution\" — the latter is\n  explicitly flagged there as a guaranteed-and-worthless negative, since its exponent `θ` is\n  always `< 1` while ours is `1.212157`.\n\nThis matches the object: `D_y(x) = sum_{e<=Q, e odd} mu(e) * int_{(a_e,x]} log(e/t) d Delta_e(t)`\nwith `Delta_e(t)` the deviation of `Lambda(n-2)mu(n)` from its density in the class\n`n ≡ -2 (mod e)`, `a_e = max(x/2, ey)` (`moving-cutoff-parity.md` (9)).\n\n## 2. Closest published result — Verified (known match for the mechanism)\n\n- **Murty–Vatwani, *Twin primes and the parity problem*, J. Number Theory 180 (2017),\n  643–659**, Theorem 1.1 and the remark on p. 647. The paper formulates the conjecture on\n  equidistribution of the Mobius function over shifted primes in arithmetic progressions for\n  a fixed even `h`, and shows it resolves the parity barrier for twin primes. It already\n  performs the squarefree-support switch, centers the shifted-Mobius progression sums around\n  their **unknown** total, and permits the **fixed residue class `-h`**. Re-read at the\n  published PDF (SHA-256 `0d53d7e1ed7879ffb0fbdb958832d9697ea37d2b261ab2db56a3cf62adbe861e`,\n  17 pp.) in `moving-cutoff-parity.md` §1, checked 2026-09-06.\n- **Vatwani, *Variants of equidistribution in arithmetic progression and the twin prime\n  conjecture*, Math. Z. 293 (2019), 285–317**, Theorems 1.2 (one odd Mobius exponent) and 1.5\n  (near-level-one hypotheses `x/exp((log x)^delta)`), read from the author preprint dated\n  2018-10-02 (SHA-256 `4eadaa6e7ca8c47cb0ef81932f105175c35d20d7956fbc89b2ea682d16a89075`).\n- Related channel (used to scope the search, not for the centered object):\n  **Lichtman, *Averages of the Mobius function on shifted primes*, QJM 73 (2022) 729–**,\n  restating the folklore conjecture `sum_{p<=X} mu(p+h) = o(pi(X))` traced to Hildebrand\n  1989; **Carella, arXiv:2206.12956** on the summatory `sum_{p<=x} mu(p+a)`.\n\n## 3. Exact difference from the closest result — Verified / Measured\n\nThe **mechanism** of #165 is not new (Murty–Vatwani, above). The **object** is not the same:\n\n1. Murty–Vatwani and its follow-ups are **asymptotic / conditional statements about means**;\n   #165 is a **finite measured census** of an explicitly centered discrepancy\n   (`D_y`, `T1`, `S`, exact-algebra residual, random-sign controls) at `x = 2^j`, `j = 16..34`.\n2. #165's `D_y(x)` keeps the **moving lower endpoint** `a_e = max(x/2, ey)` in each\n   progression, exactly the boundary that published display p. 654 of Murty–Vatwani drops\n   (`moving-cutoff-parity.md` equation (1); an exact finite counterexample at `x=20, y=3, h=2`\n   verifies the dropped condition is not cosmetic). No published statement was found that\n   computes this centered sum as a finite table.\n3. The **sufficient estimate `D_y >= -4x/25`** remains OPEN; Murty–Vatwani supply the\n   conditional implication `D_y = o(x)`, a strictly weaker allowance than `-4x/25`, and their\n   hypothesis (shifted-Mobius equidistribution) is not the same arithmetic input as a\n   one-sided lower bound at those dyadic scales.\n\n## 4. Search actually performed this run — Measured (channels) / Inconclusive (data)\n\n- Served `research/SEARCH-CONVENTIONS.md` (rid `q_WFWUsvPpz6MDaNrm`, 200) — convention named, §1 table row \"the actual Mobius-weighted prime progression discrepancy after a squarefree switch\".\n- Served `research/history/reviews-0907/01-shifted-prime-data-search.md` (rid `q_LLehfR8ddMjWj2H_`, 200, 2 739 B): its four summed objects (`sum Lambda(n-2)mu(n)`, `sum mu(p+-2)`, progressions/BV numerics, Chowla two-point) have **no published or tabulated values above `x = 10^4`**; largest published scale seen is `x = 10^4` (Carella, shift-1 Liouville). OEIS has sign-pattern sequences only.\n- This turn's `web_search` (6 queries, **control `twin primes` returned results**, so the channel was up): topical queries \"Mertens function shifted primes Mobius discrepancy\", \"Murty Vatwani twin primes parity problem squarefree divisor switching fixed residue\", \"centered discrepancy Mobius weighted prime progression moving cutoff\", \"tabulated values Lambda(n-2)mu(n) shifted prime Mobius census 10^8\". They reach the same Carella / Lichtman / OEIS / Murty–Vatwani channels; **no finite table of the centered `D_y`**.\n- **NEW LEAD (not found in the project corpus).** `A Moving-Cut Correction in the Huang-Li Conditional Goldbach Argument, and Consequences for Diagonal Mobius-Twisted Elliott-Halberstam ...`, HAL `hal-05725912v1` (posted 2026-08-25). Its own search snippet: *\"Murty and Vatwani [2017], in the twin-prime setting, formulated a Mobius equidistribution conjecture over shifted primes and showed how it can ...\"*. This is an independent treatment of a **moving-cut** defect in a conditional argument — the exact class of object `moving-cutoff-parity.md` §2 repairs locally. **Full text INACCESSIBLE this turn**: both the landing page and the `/document` URL answer the Anubis JavaScript proof-of-work page (no content; recorded as an inaccessible source, not as absence).\n- **arXiv API: channel failure.** All six queries including the control `ti:\"twin primes\"` returned no HTTP status (the `urllib` call raised) — recorded as a channel failure, never as an empty result set (this is the leg SEARCH-CONVENTIONS left owed). The web_search channel served as the live control instead.\n\n## 5. Verdict and scope\n\n- **Owned**, for the mechanism and the convention: the object is shifted-Mobius\n  equidistribution / the centered shifted-prime progression discrepancy, home = Murty–Vatwani\n  (2017) with Vatwani (2019).\n- **Exact difference**, for the object of #165: a finite measured census of an explicitly\n  centered discrepancy with a retained moving endpoint, whose sufficient bound `-4x/25` is\n  open; the published work is asymptotic/conditional and does not tabulate it.\n- **No verbatim statement of #165's census found within the stated search** — a scoped\n  negative inside the owning convention, *not* a novelty claim.\n- **IMPORT-MAP audit candidate** (lead; owed): add a row for HAL `hal-05725912v1`, whose\n  moving-cut correction may coincide with, duplicate or contradict\n  `research/moving-cutoff-parity.md` (1)/(9). Cheapest next step: retrieve the PDF through a\n  non-Anubis mirror or the authors' copies and compare its correction term with (1)/(9) — zero\n  compute. Until it is read, it is a lead, not a match.\n\n## 6. Sources inspected / inaccessible\n\nInspected at the source: SEARCH-CONVENTIONS.md, moving-cutoff-parity.md,\nhistory/reviews-0907/01-shifted-prime-data-search.md, return #165 (saved reply), plus the six\nweb_search result pages listed in `search-log.json`.\nInaccessible this turn: HAL `hal-05725912v1` (Anubis); the arXiv API (channel failure);\nSemantic Scholar was not retried (429 in earlier sessions, gotcha 51).\n\n## 7.
