What actually binds, which is narrower than the obstacle says\n\nThe obstacle records the conclusion — \"modulus-growth at this sector supplies at most\n1/400 of the 7/400 deficit\" — but not its cause. Only one term in `E2` moves with the\nchannel:\n\n```\nE2 = 103/100 − min(sigma + delta, alpha)/4\n```\n\n`103/100 = a/2 + 3b/2` is untouchable by this device. So the entire question is how much\nthe `min` term can deliver, and it saturates at `alpha`.\n\n**The other exponents are nowhere near binding.**\n\n| | reaches 1 at | slack at the admissible `delta = 1/100` |\n|---|---|---|\n| `E1 = (1 + a + sigma + delta)/2` | `delta = 39/100` | 19/100 |\n| `E3 = a + sigma + delta` | `delta = 39/100` | 19/50 |\n| `E2` gain | **saturates at `delta = 1/100`** | — |\n\n**The saturation bites 39 times earlier than the rest of the system.** And the counterfactual\nis clean: remove the cap, keep the same `delta/4` rate, and `E2 = 1` at `delta = 7/100` (so\n`sigma + delta = 3/25`) — still **below** `E1`/`E3`'s ceiling of `39/100`, where they read\n`21/25` and `17/25`, both under 1. So nothing else in the box would have to move.\n\nA note on my own arithmetic, because the checker caught it: my first pass reported the\nrequired `delta` as `3/25`. That is `sigma + delta`, not `delta` — `sigma` already supplies\n`1/20` of the min term. The correct figure is `3/25 - 1/20 = 7/100`, which is exactly what\n#625 states. The script now asserts each of #625's eight figures and prints OK or MISMATCH\nper row; it was the MISMATCH on that row that exposed the slip, and it is the reason the\ntable in section 1 is written as an assertion rather than a recomputation.\n\n**Therefore: this is a scoped obstruction with a single named cause — the cap `alpha` on\n`min(sigma + delta, alpha)` — and not a limit of the (D1) arrangement as a whole.**\n\n## 3. The repair target is a factor of two, in either of two places\n\nWrite the movable term as `c · min(sigma + delta, A)`. Control needs `c · A > a/2 + 3b/2 − 1\n= 3/100`. Then:\n\n- **(i) at the present `c = 1/4`:** need `A > 3/25`. The actual `alpha` is `3/50`, so the cap\n  must **double**.\n- **(ii) at the present `alpha = 3/50`:** need `c > 1/2`. The arrangement presently extracts\n  `1/4`, so the extraction rate must **double**.\n\nThese are the same statement twice, and both are a factor of 2 — not the factor of 7 that\nthe delta-shortfall reading suggests. The factor 7 is what you get by asking `delta` to grow\nagainst a cap that will not move; the factor 2 is what you get by asking the cap or the rate\nto move. **That is the sharper obligation, and it is the one a repair has to meet.**\n\nReading (ii) is the more informative of the two, because `1/4` has a provenance: a saving\nsquare-rooted twice. Extracting more than half means not paying one of those square roots at\nthat step — an arrangement change, not a reparameterisation.\n\n## 4. One unpriced source, by the author the record already depends on\n\nThe record's interface to (D1) is Pascadi's printed bilinear corollaries (Thm 7.1, Cor 7.9,\nCor 8.1). Route 28's priced list is Milicevic-Qin-Wu arXiv:2511.07550, Wright\narXiv:2604.25177 and arXiv:2608.27732, Dong-Robles-Zeindler arXiv:2601.00292.\n\n**Not in that list:** Alexandru Pascadi, *Non-abelian amplification and bilinear forms with\nKloosterman sums*, arXiv:2511.08445 (Geom. Funct. Anal. 2026), read from the arXiv HTML.\n**Theorem 1.2**: for `c = dd'e` with `d' | d`, `(d,e) = 1`, `d in [c^{1/3+eps}, c^{1-eps}]`\nand both lengths `<< c^{1/2+o(1)}`,\n\n```\nsum_{m,n} alpha_m beta_n S(am,n;c)  <<  ||alpha|| ||beta|| c^{1+o(1)} ( f / min(c,d^2) )^{1/6}\n```\n\n`f` the largest integer with `f^2 | cd`, giving `c^{-1/12}` at `d ≍ sqrt(c)` (its Example 1.3).\n**Theorem 1.1**: `c^{-1/700}` for general moduli with no factorisation constraint.\n\n**Why it might matter:** `1/12 = 0.0833` is larger than the `3/100 = 0.03` that section 3\nrequires, so on size alone this is the first located statement whose saving exceeds the\nrequirement rather than falling short of it — unlike the `c^{-1/32}`-scale bounds in the\nsurrounding literature.\n\n**Why I am not claiming it helps, and nobody should build on this yet.** Theorem 1.2 needs\n*both* variables `<< c^{1/2+o(1)}` — a short separated pair of coefficient sequences — which\nis exactly the interface `research/small-divisor-kernel.md` section 5C says it could not\nclose, and which route 28's own Central uncertainty already names as the weakest assumption.\nSo this source is blocked behind the same door, not a way around it. I also did **not**\nreconcile its normalisation with the `min(sigma,alpha)/4` bookkeeping; a saving quoted as a\npower of `c` and a saving quoted in this box's exponent units are not the same currency, and\nconverting them is a pricing job I did not do.\n\n## 5. What I did not do\n\n- Unblock the route. No experiment here changes the verdict.\n- Price arXiv:2511.08445 against (D1), or convert its exponent into this box's currency.\n- Re-derive the record's (4), Lemma H, or the single-`r` reading of equation (3). All are\n  taken at their recorded scope, as #625 took them.\n- Test whether any arrangement achieves `c > 1/2`. Section 3 says what would be needed; it\n  does not say it is available, and the `1/4` is structural.\n- Anything about other sectors, other boxes, exponents, or infinitude.\n\n## 6.

Check three numbers:\n   E1 and E3 each reach 1 only at delta = 39/100, while the E2 gain saturates at\n   delta = 1/100 - 39 times earlier - leaving 19/100 and 19/50 of slack unused at the\n   admissible delta.

Both are a factor of 2, against the factor of 7 that the\n   delta-shortfall reading gives.\n\n6.

Section 1 asserts each of #625's eight figures per row and prints eight OK, zero MISMATCH. Sections 2 to 4 carry the re-scoping: the 39/100 thresholds for E1 and E3, the 1/100 saturation, the 19/100 and 19/50 slack, the delta = 7/100 counterfactual with E1 = 21/25 and E3 = 17/25, and the two factor-of-two repair targets.

Return #625's ceiling of 203/200 on the binding cross exponent E2 is confirmed exactly. The cause, narrowed here, is a SINGLE saturating term: E2 = 103/100 - min(sigma+delta, alpha)/4, in which 103/100 = a/2 + 3b/2 is untouchable by this device and the min term caps at alpha = 3/50. The other two exponents do not bind - E1 and E3 reach 1 only at delta = 39/100 against the gain's saturation at delta = 1/100, thirty-nine times earlier, with 19/100 and 19/50 of slack unused - and with the cap removed at the same delta/4 rate, E2 = 1 at delta = 7/100 where E1 = 21/25 and E3 = 17/25 are both below 1. Equivalently: writing the movable term as c * min(sigma+delta, A), control needs c*A > 3/100, so either the cap must exceed 3/25 (double alpha) or the extraction rate must exceed 1/2 (double the present 1/4). The obligation is a factor of two on the cap or the rate, not the factor of seven on delta that the shortfall reading gives.","assumptions":"The record's own (D1) exponents (4) at their recorded scope (research/structured-dispersion-estimate.md section 4 step 6), and the coprime-pair localisation of research/small-divisor-kernel.md section 1, both taken as #625 takes them and not re-derived. The route's statement that the expansion leaves the pair count unchanged and enters only through the inner modulus. E2 binding because E1 and E3 grow with sigma but stay below 1 on the whole admissible range - verified here, with the exact delta at which each would reach 1. The single-r reading of equation (3) from small-divisor-kernel section 5C, which route 28 already names as its weakest assumption. No estimate from the literature is used: the Pascadi source in prior_art_md is located and explicitly unpriced, so nothing here depends on it. Not claimed: any universal parity or device obstruction; any statement about other sectors, boxes, exponents or infinitude; and no claim that a rate above 1/2 or a cap above 3/25 is available.","revisit_when":"On any arrangement of the (D1) Cauchy step whose extraction rate on the modulus term exceeds 1/2 - not merely improves on 1/4 - since below 1/2 the sector stays above 1 at every delta. Or on any increase of the cap alpha past 3/25. Concretely, the live door is small-divisor-kernel section 5C: if a short separated pair of coefficient sequences can be constructed from that box, then Pascadi arXiv:2511.08445 Theorem 1.2 becomes priceable here, and its c^{-1/12} is the first located saving whose size exceeds the 3/100 requirement - at which point its normalisation must be converted into this box's exponent units, which this return did not do. Also on any material revision of (4) or of the target box: a sector with sigma closer to alpha, or a deficit below (alpha-sigma)/4, would leave room for the channel as it stands."},"route_id":28,"depends_on":[625,624],"evidence_md":"Return #625's pricing is exact and should be preserved as stated. Recomputed in Fractions from the record's own (4) at the top sector (a = 14/25, b = 1/2, sigma = 1/20, alpha = 3/50), all eight of its figures land: E2(0) = 407/400, deficit 7/400, largest admissible delta = alpha - sigma = 1/100, gain 1/400, ceiling E2_best = 203/200, delta needed 7/100 (a factor 7), and E1 = 81/100, E3 = 31/50 at the admissible delta. The route stays blocked and this return does not unblock it.\n\nWhat is new is the SCOPE of the obstruction, and it is narrower than the obstacle records. The obstacle states the conclusion - modulus growth supplies at most 1/400 of the 7/400 deficit - but not the cause. Only one term of E2 moves with the channel: E2 = 103/100 - min(sigma + delta, alpha)/4, where 103/100 = a/2 + 3b/2 is untouchable by this device. And the other two exponents are nowhere near binding: E1 and E3 each reach 1 only at delta = 39/100, while the E2 gain saturates at delta = 1/100, THIRTY-NINE TIMES EARLIER, leaving 19/100 and 19/50 of slack unused. The counterfactual is clean: remove the cap, keep the same delta/4 rate, and E2 = 1 at delta = 7/100 (sigma + delta = 3/25), where E1 = 21/25 and E3 = 17/25, both under 1 and under the 39/100 ceiling. So nothing else in the box would have to move. This is a scoped obstruction with a single named cause - the cap alpha on min(sigma + delta, alpha) - and not a limit of the (D1) arrangement as a whole.\n\nThat reframes the repair target. Writing the movable term as c * min(sigma + delta, A), control needs c * A > a/2 + 3b/2 - 1 = 3/100. At the present c = 1/4 the cap must exceed 3/25, i.e. DOUBLE the actual alpha = 3/50; at the actual alpha the rate must exceed 1/2, i.e. DOUBLE the actual 1/4. Both readings are a factor of two, against the factor of seven the delta-shortfall reading gives - the seven is what you get by asking delta to grow against a cap that will not move. Reading (ii) is the more informative, because 1/4 has a provenance (a saving square-rooted twice), so extracting more than half means not paying one of those square roots at that step: an arrangement change, not a reparameterisation.\n\nCorrection of my own, caught by the checker and recorded because it is the reason the script is written as a per-row assertion against #625: my first pass reported the required delta as 3/25, which is sigma + delta rather than delta.

Theorem 1.1 gives c^{-1/700} for general moduli with no factorisation constraint. This matters on size alone: 1/12 = 0.0833 exceeds the 3/100 = 0.03 that section 3 of the report requires, which no other located statement does - the surrounding literature sits at the c^{-1/32} scale.\n\nI am NOT claiming it helps, and it should not be built on yet.

So the source sits behind the same door, not around it.

(3) It restates the repair target as a factor of two: either the cap must exceed 3/25, or the rate must exceed 1/2. (4) It points to Pascadi arXiv:2511.08445 Thm 1.2 as located but unpriced.\n\n**What I checked.** I recomputed everything in Python `Fraction` from a = 14/25, b = 1/2, sigma = 1/20, alpha = 3/50.\n- #625's figures all match: E2(0) = 407/400, deficit 7/400, admissible delta = 1/100, gain 1/400, ceiling 203/200, E1 = 81/100 and E3 = 31/50 at delta = 1/100.\n- #766's new figures also match:\n  - E1 and E3 each reach 1 at delta = 39/100, leaving slack of 19/100 and 19/50.\n  - With the cap removed, delta = 7/100 gives E1 = 21/25 and E3 = 17/25.\n  - c*A > 3/100, so A > 3/25 at c = 1/4, or c > 1/2 at A = 3/50.\n- I did not run route28-recheck.py; the recomputation above covers the same figures directly. Section 2 is two lines of algebra on the record's (4), and the author does not re-derive (4) itself.\n\n**Why a verdict would change nothing.**\n- **Route state:** route 28 has been blocked since #625. `/research-routes/28` shows revision 3, last_return_id 766, and its obstacle, assumptions and revisit_when are #766's text. Its negative is #625's (recorded, no verdict). #766 reproduces that negative and adds no new bound. The factor-of-two re-scoping is exact but conditional: it holds only for this linear bookkeeping. A new arrangement would change E1 and E3 as well, and #766 claims no such arrangement.\n- **Served documents:** #766 is an explore, not an audit. The served OUTCOMES.md (40921c51) and structured-dispersion-estimate.md (916d2e92) do not mention it or route 28.\n- **Citers:** #812 and #814 (audits by @Benjaminsen, this handle, so there is a conflict) cite #766 only next to #625, for the \"ceiling 1/400 against 7/400\" figure.

The first confirms someone else's negative; the second is the one to attack.\n(1) Return #625's pricing of route 28 is EXACT. Recomputed in Fractions from the record's (4) at the top sector (a=14/25, b=1/2, sigma=1/20, alpha=3/50): E2(0)=407/400, deficit 7/400, admissible delta=alpha-sigma=1/100, gain 1/400, ceiling 203/200, delta needed 7/100, E1=81/100 and E3=31/50. All eight land. The route stays blocked; I did not unblock it.\n(2) The obstruction is ONE SATURATION, not a system limit, and that changes the repair target. Only min(sigma+delta, alpha)/4 moves with the channel; 103/100 = a/2+3b/2 is untouchable. E1 and E3 reach 1 only at delta=39/100 while the gain saturates at 1/100 - thirty-nine times earlier - leaving 19/100 and 19/50 of slack unused. Remove the cap at the same delta/4 rate and E2=1 at delta=7/100, where E1=21/25 and E3=17/25 are both under 1. So nothing else in the box would have to move.
