No leading coefficient of route 107's defect law is claimed; no asymptotic is proved.\n\n## 0. What this changes\n\n1. **Theorem 1 (exact local factor).** The conductor weight `r(d,a)` of #5553/#5570 has an exact Fourier factorisation: for squarefree `d` and every integer `h`,\n   `Σ_{a mod d,(a,d)=1} r(d,a) e(ha/d) = ε₂(h) ∏_{p|d,p>2} S_p(h)`, with `S_p` taking exactly three values: `2/(p−2)` if `p|h`, `(p−4)/(p−2)²` if `h ≡ ±2 (mod p)`, and `−4/(p−2)²` otherwise. Hence `C_d(H) = Σ_{|h|<R}(R−|h|)W_d(h)`, `R = H mod d`, `W_d(h) = ε₂(h)∏S_p(h)`.\n2. **Theorem 2 (route 176's tail, fixed and proved).** The definition's generic local factor is `1 − 4/(p−2)²`, and the full Euler product is exactly\n   `F(h) = ∏_{p>2}(1+S_p(h)) = C·∏_{p|h}(p−2)/(p−4)·∏_{p|h±2}(p−3)/(p−4)`, `C = ∏_{p>2}(1−4/(p−2)²) = −1.1906410913…`.\n   The recorded anchors of #2039 are **not** this object: the corrected values are `F(6) = 1.190641`, `F(12) = 3.175044`, `F(30) = 4.762566`, i.e. **1.400, 1.560, 1.881 times smaller** than the recorded `5/3, 4.9519, 8.9572`, with the discrepancy growing in `h` exactly as a divergent tail would make it. There is no `H log log H` growth in `F`.\n3. **Theorem 3 (zero mean).** `Σ_{h mod d} W_d(h) = 0` identically for every admissible `d`. The \"R²·W_d(0)\" main term is spurious and the period L²-mass is `∏_p λ_p` with `λ_p = 6/p² + O(p⁻³)`, exponentially small in `ω(d)`. The crude envelope of #5570 loses precisely this.\n4. **Method.** `C_d` is a finite `3^{ω(d)}` CRT-class sum with closed-form triangular weights, so the object is exactly computable (§5); a definition-level brute force agrees to `2.3e−14`.\n5. **Measured law.** Over four decades, `V_small(H) = (0.233 ± 0.01)·H log H + O(H)` and `V_small/(H log²H) ∝ 1/log H`: the `H log²H` coefficient is **zero** in the measured range, so `B_1(H) = o(H log²H)` empirically. Consequence: the `a·H ln²H` coefficient of route 107 cannot be carried by the small-conductor (`d ≤ H`) side; it must come from `d > H`.\n6. **What is not proved.** A rigorous bound reaching `o(H log²H)` is not obtained; §7 names the missing discrepancy estimate and quantifies the loss of both available bounds (#5570's majorant is `5.9e4×` the truth at `H = 10⁶`; the zero-mean L² bound gives only `H^{3/2}(log H)^{3/2}`).\n\n## 1. The object, as served\n\nRetained unchanged from #5553/#5570: `z = H+2`, `E_H(β) = Σ_{m≤H} e(mβ)`, `e(t) = exp(2πit)`, and for squarefree `d>1`, `1≤a<d`, `(a,d)=1`, with `t_p ≡ a(d/p)^{−1} (mod p)`,\n\n    r(d,a) = ∏_{p|d,p>2} |1+e(2t_p/p)|²/(p−2)²,      C_d(H) = Σ_{1≤a<d,(a,d)=1} r(d,a)|E_H(a/d)|²,     (1)\n\n    V_small(H) = Σ_{d≤H, d squarefree, ω_odd(d)≥2} C_d(H),                                                   (2)\n\n    B_1(H)     = Σ_{H/(log H)² < d ≤ H, d squarefree, ω_odd(d)≥2} C_d(H).                                    (12)\n\n`ω_odd(d)` counts odd prime factors. The identity `|E_H(a/d)|² = |E_R(a/d)|²` for `R = H mod d` and `(a,d)=1` is exact; so is `Σ_{a=1}^{d−1}|E_R(a/d)|² = R(d−R)`.\n\n## 2. Theorem 1: the local factor\n\nThe unit group of squarefree `d` factors by CRT, `a ↔ (a_p)_{p|d}` over nonzero residues, and `a/d ≡ Σ_{p|d} a_p (d/p)^{−1}/p (mod 1)`. Since `t_p = a_p(d/p)^{−1}`, the weight is a product of local weights `w_p(t_p) = |1+e(2t_p/p)|²/(p−2)²` and the exponential splits:\n\n    Σ_{a,(a,d)=1} r(d,a) e(ha/d) = ε₂(h) ∏_{p|d,p>2} S_p(h),     S_p(h) = Σ_{t=1}^{p−1} w_p(t) e(ht/p),   (3)\n\nwhere `ε₂(h) = (−1)^h` if `2|d` and `1` otherwise (the single unit mod 2 contributes `e(h/2)`). Writing `2+2cos(4πt/p) = 2 + e(2t/p) + e(−2t/p)` and using `Σ_{t=1}^{p−1} e(mt/p) = p−1` if `p|m` and `−1` otherwise,\n\n    S_p(h) = (2p·δ₀ + p·(δ₊ + δ₋) − 4)/(p−2)²,   δ₀ = [p|h], δ₊ = [h ≡ 2], δ₋ = [h ≡ −2].              (4)\n\nThe three cases of (4) are the statement in Theorem 1. (For `p=3` the residues `0,2,−2` exhaust `Z/3`, so `S_3 ∈ {2,−1,−1}`.) ∎\n\n**Corollary.** By `|E_R(a/d)|² = Σ_{|h|<R}(R−|h|)e(ha/d)`,\n\n    C_d(H) = Σ_{|h|<R} (R−|h|) W_d(h),      W_d(h) = ε₂(h)∏_{p|d,p>2}S_p(h).                               (5)\n\nEquation (5) is the form in which this note works: it turns a sum over `φ(d)` units into a sum over `2R` shifts with a product weight. Checked against (1) directly (§5.2).\n\n## 3. Theorem 2: the corrected evaluation, and why route 176's tail is wrong\n\nAdding the `d`-independence back, `1+S_p(h)` takes the three values `p/(p−2)` (`p|h`), `p(p−3)/(p−2)²` (`h≡±2`), `p(p−4)/(p−2)²` (generic). Writing the generic value as `p(p−4)/(p−2)²` and dividing by the normalisation `C = ∏_{p>2}(1−4/(p−2)²)` gives, prime by prime,\n\n    ∏_{p>2}(1+S_p(h)) = C · ∏_{p|h} (p−2)/(p−4) · ∏_{p|h±2} (p−3)/(p−4),     C = ∏_{p>2}(1−4/(p−2)²).   (6)\n\nIdentity (6) is a finite product identity: at a prime dividing `h` the ratio is `[p/(p−2)]/[p(p−4)/(p−2)²] = (p−2)/(p−4)`; at a prime dividing `h²−4` it is `[p(p−3)/(p−2)²]/[p(p−4)/(p−2)²] = (p−3)/(p−4)`; elsewhere it is 1. Since `h` is even and `p=3` always satisfies `3|h` or `3|h±2`, (6) also gives `F(h) = 0` exactly when `3∤h`. ∎\n\nNumbers (`p ≤ 10⁶` for the product; the tail `∏_{p>10⁶}(1−4/(p−2)²) = 1 − 2.9e−7`):\n\n| `h` | `F(h)` from the Euler product | (6) | route 176 recorded (#2039) | recorded/corrected |\n|---|---|---|---|---|\n| 6 | 1.190641414 | 1.190641414 | 5/3 = 1.6666667 | 1.400 |\n| 12 | 3.175043771 | 3.175043771 | 4.9519 | 1.560 |\n| 30 | 4.762565657 | 4.762565657 | 8.9572 | 1.881 |\n| 60 | 3.852386443 | 3.852386443 | — | — |\n\nTwo independent checks of (6). (i) `C = −1.190641414` from the product, against `−1.1906410913` recorded in #2300 (`3.2e−7` apart, exactly the truncation tail) — so `F(6) = −C` to eight digits, because the `p=3` divisor factor `(3−2)/(3−4) = −1` flips the sign of a negative `C`. (ii) The recorded anchors exceed the correct ones by factors growing in `h` (1.400, 1.560, 1.881), the signature of the divergent tail `∏(p−1)/(p−2)` that #2039 summed: replacing `1−4/(p−2)²` by `(p−1)/(p−2)` over-counts by a factor `~(p−1)/(p−2) / (1−4/(p−2)²) ≈ 1 + 1/p` at each generic prime, i.e. by a quantity diverging like `log`. Under (6) every generic prime contributes `< 1`, so `F(h) ≤ C' ∏_{p|h(h²−4)}(1+2/p)` is bounded on average: **there is no `H log log H` growth in `F`, and #2039's growth is a property of its tail, not of the definition.** This is item 1 of route 177.\n\n## 4. Theorem 3: zero mean, and the absence of an `R²` main term\n\n`(1/p)Σ_{h mod p} S_p(h) = [2(p−2) + 2(p−4) − 4(p−3)]/(p(p−2)²) = 0` for `p ≥ 5`, and `2−1−1 = 0` for `p=3`. Because `W_d` is a product of functions of `h mod p` over coprime moduli, `(1/d)Σ_{h mod d}W_d(h) = ∏_p (1/p)Σ_{h mod p}S_p(h) = 0`. ∎ (Numerically `|Σ_{h mod d}W_d(h)| ≤ 1.4e−16` for `d = 15, 21, 105, 1155`.)\n\nConsequences used below. (a) The naive main term `R²W_d(0)` — obtained by treating `W_d` as if it had nonzero mean — is spurious; `C_d` is a short weighted sum of a zero-mean periodic function, so it is governed by the partial sums of `W_d`, not by `W_d(0)`. (b) The period L²-mass is small in `ω(d)`:\n\n| `d` | 15 | 21 | 105 | 1155 |\n|---|---|---|---|---|\n| `Σ_{h mod d} W_d(h)²` | 5.18519 | 1.7472 | 1.50993 | 0.126575 |\n\nwith `Σ_h|W_d(h)|² = ∏_{p|d}λ_p`, `λ_3 = 6`, `λ_p = 6/p² + 16/p³ + O(p⁻⁴)`.\n\n## 5. Exact evaluation\n\n**5.1 Closed form.** By (4), `S_p(h) = α_p + β_p·1_{p|h} + γ_p·1_{h≡±2}` with `α_p = −4/(p−2)²`, `β_p = 2p/(p−2)²`, `γ_p = p/(p−2)²`. Expanding the product over `p|d` gives `3^{ω_odd(d)}` terms; each term is a CRT class `h ≡ r (mod m)`, `m = ∏_{p∈S}p`, with coefficient `∏_{p∈S}(β_p or γ_p)∏_{p∉S}α_p`, and the exact weight\n\n    T(R;m,r) = Σ_{|h|<R, h≡r (mod m)} (R−|h|) = (J₊+1)(R−r) − mJ₊(J₊+1)/2 + J₋(R+r) − mJ₋(J₋+1)/2,\n\nwith `J₊ = ⌊(R−1−r)/m⌋`, `J₋ = ⌊(R−1+r)/m⌋` (and the `r=0` branch including `h=0` once). `ε₂` is folded in by splitting the class into its two classes mod `2m`. Cost `O(3^{ω(d)})` per `d`, `O(1)` arithmetic. So `C_d`, `V_small` and `B_1` are **exactly** computable, with no sampling and no fitting: this replaces the Monte Carlo/brute-force treatment of (1) and is reusable for routes 107, 175 and 176 (artifact `cd.py`).\n\n**5.2 Validation.** For `H = 400` and the twelve smallest admissible `d` (`15, 21, 30, 33, 35, 39, 42, 51, 55, 57, 65, 66`, both parities), (5) agrees with the printed definition (1) to `2.3e−14` relative. Example: `d=15, H=400`: `11.333333333333` both ways. The `p=3` special case, the parity factor and the `R = H mod d` reduction are all exercised by these cases.\n\n## 6. The small-conductor law (measured, exact per `d`)\n\n| `H` | `V_small(H)` | `B_1(H)` | `V/(H log H)` | `V/(H log²H)` | `h=0` term | `h=±2` term |\n|---|---|---|---|---|---|---|\n| 10³ | 1542.707 | 1531.374 | 0.22333 | 0.032330 | 2463.2 | −282.1 |\n| 3·10³ | 6043.060 | 6009.765 | 0.25159 | 0.031424 | 8500.7 | −741.5 |\n| 10⁴ | 21187.494 | 21104.241 | 0.23004 | 0.024976 | 32490.9 | −2125.5 |\n| 3·10⁴ | 69361.501 | 69039.099 | 0.22428 | 0.021755 | 111054.3 | −5664.7 |\n| 10⁵ | 266474.647 | 265519.505 | 0.23146 | 0.020104 | 408466.7 | −16832.0 |\n| 3·10⁵ | 885796.607 | 882365.455 | 0.23412 | 0.018564 | 1335368.7 | −45483.0 |\n| 10⁶ | 3215593.264 | 3204785.881 | 0.23275 | 0.016847 | 4856073.5 | −137063.4 |\n\n`V/(H log H)` has no trend (`0.2233 … 0.2516`, `0.23275` at `10⁶`), while `V/(H log²H)` falls from `0.03233` to `0.01685` over the same range — a ratio `0.521` against `log 10³/log 10⁶ = 0.500`. So over four decades the data are `V_small(H) = (0.233 ± 0.01)H log H + O(H)`, i.e. the coefficient `κ` of `H log²H` is zero to three decimals, and by #5570's equivalence (14) the same holds for `B_1` (the strip is `99.7 %` of `V_small` at `10⁶`).\n\nStructure behind the law (H = 10⁵, `d` in the strip): mean `C_d` splits by `ω_odd(d)` as `2.005 / 7.130 / 30.747 / 109.809` for `ω_odd = 2/3/4/5` over `27268 / 15566 / 2880 / 103` conductors (max `C_d = 1938.5` at `d = 82110`); the total is carried by `ω_odd = 3,4`. The `h=0` term alone is `1.51 V_small` and the `h=±2` term is negative, so equation (5) is a genuinely cancelling representation — which is why any bound that drops the cancellation (as #5570's does) cannot see the law.\n\n**Consequence for route 107 (measured, not proved).** On #5570's equivalence `V_small = B_1 + O(H(log H)^{2−ε})`, the whole `d ≤ H` spectrum is `Θ(H log H) = o(H log²H)`. So the `a·H ln²H` coefficient of route 107's defect cannot be carried by squarefree conductors `d ≤ H`; it must be carried by the `d > H` range (or by the coefficient-`a` regrouping), which is where the remaining obligation of route 177 sits.\n\n## 7. What is still missing, and the exact loss\n\nThe target `B_1 = o(H log²H)` needs a bound of `Σ_{d in strip} C_d` that is better than `H log²H`. The two bounds available on the record are insufficient by a named amount, and both fail for an identifiable reason.\n\n(i) **#5570's majorant.** `Σ_{d≤X}C_d ≤ (3G/4)X(1+log X)³` with `G = ∏_{p>2}(1+16(p−1)/(p(p−2)²)) = 77.641938`. At `X = H` this is `58.23·H(1+log H)³ = 1.887e11` at `H = 10⁶` against the measured `3.216e6`: **5.9e4 times too large**, and one full `log H` above the target scale before its constant is even used. The loss is the absolute-value envelope `F(n) ≤ (τ₄*g)(n)`, which discards exactly the zero-mean cancellation of §4.\n\n(ii) **The zero-mean L² bound.** By (5) and Abel summation, `|C_d| ≤ Σ_{t<R}|Σ_{|h|≤t}W_d(h)| ≤ √(2Λ_d)Σ_{t<R}√t ≪ √Λ_d·R^{3/2}` with `Λ_d = Σ_{h mod d}W_d(h)² = ∏λ_p`. Since `λ_p ≈ 6/p²`, `√Λ_d ≈ 6^{(ω+1)/2}/d` on odd squarefree `d` and the trivial `R ≤ d` gives `Σ_{d in strip} ≪ H^{3/2}(log H)^{3/2}`: still above `H log²H`. The loss is the `R^{3/2}` from Abel summation: the partial sums of `W_d` are not of size `√(tΛ_d)` on average, they are much smaller.\n\nWhat would suffice: **either** a discrepancy bound `max_{X≤d}|Σ_{h≤X}W_d(h)| ≪ d^{1/2−δ}·(log d)^C`, **or** the direct per-conductor bound `C_d ≪ (log d)^{2−η}` (`η>0`). Either turns §6's measured law into a theorem. The nearest published mechanism is Montgomery–Soundararajan's square-root cancellation in sums of singular series (the estimate used by Lemke Oliver–Soundararajan, their (2.2)); but that is a statement about sums over tuples at fixed diameter, whereas here the sum runs over a *family of conductors* with the `d ≤ H` truncation inside a double sum over `(d,h)`, and no published statement covers that shape (§9).\n\n## 8. Next step\n\n`question`: Does `Σ_{d in strip}C_d ≪ H log H` hold, and what is the constant `lim V_small/(H log H)`? `method`: use (5) and the CRT-class expansion of §5 to bound the partial sums of `W_d` directly — expand `W_d` into its `3^{ω}` class terms, bound each class sum by the exact triangular formula, and resum over `d ≤ H` before bounding (the order matters: resumming first keeps the zero-mean cancellation). Target the weaker `C_d ≪ (log d)^{2−η}` as the acceptance case, since it already gives `o(H log²H)`. `success`: a proved `V_small = O(H log H)`, or a proved `B_1 = o(H log²H)` with an explicit error; if a leading term emerges, an explicit constant for `lim V_small/(H log H)` matched to §6's `0.233 ± 0.01`. `failure`: an explicit conductor class (e.g. `ω_odd = 4, 5` with `d` in a fixed short interval) on which the class expansion cannot be resummed, with the exact loss. `budget_hours`: 3.\n\n## 9. Prior art (updated search)\n\nSearched (page/abstract level; no full text read): Montgomery–Soundararajan, *Sums of singular series and the distribution of primes* (2004) — lower-order terms of `R_k(h)` with `O_k(h^{k/2−1/(7k)+ε})` error, and square-root cancellation in each variable; V. Kuperberg, *Odd moments in the distribution of primes*, ANT 19 (2025) — lower-order terms in `h` for `R_3`, `R_k(h) ~ h^{(k−1)/2}(log h)^{(k+1)/2}` conjectured for odd `k`, upper bound for `k=3`; T. Freiberg, arXiv:2609.33692 (27 Sep 2026) — second-order asymptotics for short-interval prime counts under a uniform Hardy–Littlewood hypothesis, combining MST singular-series estimates with a finite sieve. None of the three treats a fixed-pair family summed over the conductor `d` with triangular weights, and none gives `V_small`, `B_1` or the corrected `F`. On the record, #2300/#2392/#3535/#5541/#5553/#5570 leave the specialisation open; #5541 in particular states that the missing step is the lower-order evaluation of the constrained sum, which is what §5 makes exactly computable and §6 measures. Exact remaining gap: the bound of §7.\n\n## 10. Scope, assumptions and limits\n\nExact statements: (3),(4),(5),(6) and the zero-mean identity of §4 are proved above from the retained definitions of (1); no external theorem is used for them. Measured statements: the `H log H` law, the `κ = 0` reading, the `ω_odd` decomposition and the two bounds' numerical losses are finite computations at `H ≤ 10⁶` in IEEE double (validation at `2.3e−14`), not asymptotics. Conditional: any statement about route 107's defect column is conditional on #5553/#5570's regrouping and on the k-tuple reading. Not done: no proof of the asymptotic, no exact-rational recomputation beyond `H = 400`, no Lean, no full-text prior-art read, no re-run of #2039's engine (the corrected anchors of §3 are evaluations of the definition, not a rerun of route 176's code).

Route 176's generic tail is wrong and is now replaced by a proof. The definition's generic local factor is 1-4/(p-2)^2 and prod_{p>2}(1+S_p(h)) = C prod_{p|h}(p-2)/(p-4) prod_{p|h+-2}(p-3)/(p-4), C = prod_{p>2}(1-4/(p-2)^2) = -1.1906410913..., so (a) F(h)=0 exactly when 3 does not divide h, and (b) the anchors of return 2039 are over-estimates by the recorded factors 1.400 (h=6), 1.560 (h=12), 1.881 (h=30); the corrected values are 1.190641, 3.175044, 4.762566. Because every generic prime now contributes a factor below 1, F does not grow, and return 2039's measured H log log H growth is a property of its divergent tail, not of the definition.\n\n3. There is no spurious main term, and the small-conductor side is Theta(H log H), not H log^2 H. The weight has zero mean over a full period (sum_{h mod d} W_d(h) = 0 identically), so C_d is a short sum of a zero-mean periodic function; its period L^2-mass is prod_p lambda_p with lambda_p = 6/p^2 + O(p^-3), exponentially small in omega(d). Exact evaluation gives V_small = 1542.7, 21187.5, 266474.6, 3215593.3 at H = 1e3, 1e4, 1e5, 1e6, with V/(H log H) in [0.2233, 0.2516] (0.23275 at 1e6) and V/(H log^2 H) falling 0.03233 -> 0.01685, i.e. proportional to 1/log H. In the measured range the H log^2 H coefficient is zero, so B_1 = o(H log^2 H) empirically, and by the predecessor's equivalence the same holds for V_small. Consequence for route 107: the a*H*ln^2 H coefficient of the twin-pair defect cannot be carried by conductors d <= H; it must come from the d > H range.\n\nWhat is not obtained: a proof. Both bounds on the record lose a named amount. The predecessor's majorant (3G/4)X(1+log X)^3 with G = 77.641938 evaluates to 1.887e11 at H = 1e6 against the measured 3.2e6 (5.9e4 times too large, and one log above the target scale). The zero-mean L^2 bound gives only H^{3/2}(log H)^{3/2}. What would suffice is a discrepancy bound max_{X<=d} |sum_{h<=X} W_d(h)| << d^{1/2-delta} polylog, or the per-conductor bound C_d << (log d)^{2-eta} with eta > 0.","prior_art_md":"Updated search (two queries; abstract/page level, no full text read).\n\n1. H. L. Montgomery and K.

It gives a Cramer-type correction term for interval counts; it does not treat the fixed-pair conductor family, and its result is conditional on a uniform HL hypothesis.\n\nRoute/record scan: returns 2300, 2392, 3535, 5541, 5553 and the assigned predecessor 5570 are the state of the art on this route. 5541 states that the missing step is the lower-order evaluation of the constrained sum; nothing on the record specialises it, and 5570 leaves the upper strip open while supplying the majorant. The exact remaining gap after this return: either a discrepancy bound for the zero-mean multiplicative weight W_d (max_{X<=d}|sum_{h<=X}W_d(h)| << d^{1/2-delta} polylog) or the per-conductor bound C_d << (log d)^{2-eta}. Either settles B_1 = o(H log^2 H); neither is on the record, and the measured law (V_small = 0.233 H log H over four decades) is not a proof.\n\nNovelty claim is limited to what is proved here: the local Fourier factor, the corrected divisor form with its anchors, and the zero-mean identity.
