Nothing here bounds D^(e₁),\nD_y, or twin-prime infinitude (OPEN). It records the outcome of the route search after route 96 was\ntriaged to blocked, so the discovery lane does not re-issue the same lead without the gap.\n\n## What I did\n\nI proposed route 96 (one-sided signed discrepancy as a strictly-weaker-than-Murty–Vatwani input) in\nreturn #1205, and its triage (return #1206) blocked it on a precise obstacle: the borrowed signed\ntwo-point correlation theorems (Tao arXiv:1509.05422; Matomäki–Radziwiłł–Tao 2016) are proved for\n1-bounded multiplicative functions, and the target weight f(n) = Λ(n−2)μ(n) has the unbounded von\nMangoldt factor, so no located theorem transfers.\n\nI then examined the natural \"changed ingredient\" for route 96's revisit_when — the **bounded-factor\ndecomposition** Λ = μ * log (Λ(n−2) = Σ_{d|n−2} μ(d) log((n−2)/d)). This does not reach the\nbounded-correlation scope either: it replaces the unbounded Λ weight with an unbounded log weight\nand a divisor relation, so the shift-2 sum becomes a three-way μ(n)μ(d) correlation with a log\nweight over a divisor condition — still outside the two-point bounded-function theorems. This is a\nconcrete (and negative) check, recorded here rather than proposed as a route.\n\n## The scoped gap (precise)\n\nThe weakest sufficient twin input on the centered-discrepancy lane remains the one-sided signed\nestimate D^(e₁) ≥ −4x/25 + o(x) over odd squarefree moduli e < x^(1/2+ε), class −2, dyadic prefix.\nIts unlocated ingredient is, precisely: a **signed estimate for an unbounded weight** at shift 2 —\neither a Λ–μ or Λ–λ two-point correlation with a non-trivial saving, or a decomposition that keeps\nonly a bounded signed factor while paying the Λ weight by a classical estimate. Route 96 (signed\nbounded-correlation theorems) and the bounded-factor decomposition both fail to supply it; the\nabsolute-value sieve forms (Maynard/BFI/Polymath/Drappeau) are recorded as not admitting the signed\nweight. No further concrete route with a distinct object and a cheap refutation is available to me\nthis assignment.\n\n## Rungs\n\n| Claim | Rung |\n|---|---|\n| Route 96 blocked: signed theorems are bounded-function only | **verified** (Tao abstract; #1206) |\n| Λ = μ*log decomposition does not reach bounded-correlation scope | **heuristic** (direct structural check; log weight + divisor relation remain) |\n| D^(e₁) ≥ −4x/25 is the weakest sufficient input with the ingredient unlocated | **verified** (note §3a/§4, #1201/#1206) |\n\n## Next step\n\nNone proposed (no new route). The scoped gap is recorded; a future route needs a signed\nunbounded-weight estimate or a bounded-factor decomposition that controls the log weight — neither\nof which I can make concrete now.\n\n## Returns built on\n\n#1205 (route 96 proposal), #1206 (its triage), #1201 (prior art), #83 (object); Tao arXiv:1509.05422.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":"heuristic","status":"recorded","final_rung":"recorded","created_at":"2026-09-19T09:35:28.192Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[1205,1206,1201,83],"messages":[]},"tokens":{"log":"custom","input":495,"models":{"deepseek-v4-pro":5578},"output":5578,"source":"custom-jsonl","entries":2,"cache_read":752512,"cache_write":0,"observed_models":["deepseek-v4-pro"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_23424801c73890cd6fd3264c","run_id":"run_6229e245d18f3644388a3a4d","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"victor-geere","job_brief":"This assignment uses the project's reserved discovery capacity for your tier, even while other jobs are queued.
