Nothing here bears on the twin prime conjecture.\n\n## 1. The candidate, and the match that closes it\n\nReturn #1217 proved a lemma: a half-range logarithmically averaged one-sided bound Σ_{√X<n≤X} a_n/n ≥ −c′ log X − o(log X), together with an a priori D(t) ≤ Kt, gives D(t) ≥ −ct at some t ∈ [√X, X] for every c > 2c′; it called the log-averaged form \"a weaker requirement\", with (ii) as \"the price\". Return #1242 (today) showed hypothesis (ii) is free for the remainders B and D_y (Selberg's upper-bound sieve on S), and read the consumer in prefix form with cutoffs frozen at the top scale. The natural route was therefore: replace route 96's dyadic requirement by the log-averaged one, the shape in which fixed-shift two-point theorems for bounded multiplicative functions exist (Tao 2016; quantitative successors).\n\nThe register already has this, from the other direction. `consumer-comparison.md` §2 item 3 and the independent handoff review F1 (2026-09-06) prove that the cumulative consumer Σ_{i≤j} S(2^i) ≥ c·2^j/j^K on an unbounded set of j is **equivalent** to the dyadic consumer at the same K with a changed constant: S ≥ 0 gives dyadic ⇒ cumulative, and Σ_{i≤j} 2^i/i^K = (2+o(1))2^j/j^K gives cumulative ⇒ dyadic with constant c/4. OUTCOMES closes \"strictly weakening the unbounded-scale dyadic consumer merely by cumulative summation\" as a REFUTED DEDUCTION. The logarithmic average is the cumulative consumer with weights 1/n, and the #1217 lemma is the cumulative ⇒ prefix direction with the sieve bound in place of nonnegativity (the log-weighted form needs the upper a priori bound where the dyadic-block form needs S ≥ 0; both are free). Two consequences, both PROVEN and elementary:\n\n1. The log-averaged one-sided requirement is not weaker than the dyadic one; it is the same requirement up to a factor 2 in the constant and the witnessing scales. The word \"weaker\" in #1217 §2 and \"reshapes the requirement\" in #1242 §3 should read \"reformulates\". The lemma and the a priori bound stand.\n2. Consequently a log-averaged fixed-shift theorem would have to deliver the full one-sided constant for the Λ-weighted sequence; the bounded-partner theorems (Tao 2016 Theorem 1.3; the Fourier-superposition import of `prime-band-transfer.md` via Tao–Teräväinen 2512.01739 Theorem 3.1) give scale-average savings and no every-dyadic or every-prefix bound, as that note records. The barrier located in #2513 and #1217 (the fixed shift with the unbounded Λ) is unchanged by the averaging shape.\n\n## 2. The gap, precisely scoped\n\nWhat is open for route 96 (and routes 50, 51, which were driven to the same obstruction): an unconditional estimate for Σ_{n≤X} Λ(n−2)μ(n)w_n at the fixed shift 2 with a one-sided saving, in either the natural or the logarithmic average (equivalent up to constants by §1), for a divisor-sum weight w_n of the note's shape. What exists (spot check of the literature today, plus the corpus records): averages over shifts h ≤ H, now with H as small as (log log X)^{ω(1)} (Lichtman, QJM 2021) and with Λ and divisor correlations included (Lichtman–Teräväinen 2021); fixed-shift results only for bounded functions (Tao 2016; Helfgott–Radziwiłł; Guo 2026 across shift scales) or under Siegel zeros (Tao–Teräväinen 2021). The shift average cannot select h = 2 (fixed-endpoint-discrepancy §4.4). Nothing found today changes that, and the negative-part majorant (candidate C) and the bounded-partner substitution (candidate B) are both closed in the register. Rung: MEASURED against the record and two online queries; not a proof of absence.\n\n## 3. The other candidates\n\n`routes-considered2539.md` lists eight candidates with the record row or route that covers each: the vector sieve for the G₂ exponent (5.158 > β₂, derive-0904-L7-transfer), remainder oscillation beyond the interval length (the extremal windows are where it fails), cheap refutation certificates for the A144311 ladder (today's #1239: cost at fixed margin grows too fast with n; route 97 holds the pruning-bound route), a second-order Mertens model for route 93 (a next step of an active route, which its own record says is not a route to the exponent), and the minimal-graph Janson bracket (route 68, blocked, experiment already defined). None changes an assumption of a blocked route in a way the register does not already price.\n\n## 4. What was not done\n\nNo computation. No sub-agents. The online search was two queries and three arXiv records (sources2539.md), not a survey; the corpus's search records are the standing ones. 70 of this handle's returns wait for a verdict.\n\nFiles: routes-considered2539.md, sources2539.md.
