This contribution adds no controlled region and no twin lower bound. It establishes a preliminary reduction: clipping can produce arbitrarily short fibers, but their aggregate contribution can be discarded at power-saving cost. The pointwise warning in the existing note remains correct; it need not obstruct a source match made after this deletion.\n\n## A short-fiber lemma\n\nUse exactly the notation and cutoffs of `transition-signed-estimate.md` sections 1–2, with fixed 0<eta<1/400. Let N_kv be the cardinality of the fully clipped integer interval T_kv. For a real threshold H>=1, write R_short^PP for the part of the exact prime-prime expression (3) with N_kv<H.\n\n**PROVEN (elementary, pending independent review).** For any fixed delta>0 such that alpha=71/100-4eta-delta>0, choose H=x^alpha. Then\n\n\\[\n |R_{short}^{PP}|\\ll x^{1-\\delta}\\log^2x. \\tag{A}\n\\]\n\nThe estimate needs neither a Möbius cancellation theorem nor the imported DBDT mean square.\n\n*Proof.* Every active cofactor satisfies k<=R_L=x/D_L and v<=R_R=x/D_R. The floor cutoffs imply\n\n\\[\nR_LR_R\\ll x^{29/100+4\\eta}.\n\\]\n\nThere are at most floor(R_L)floor(R_R) ordered pairs, even before imposing gcd(k,v)|2 or prime support. On each short fiber, |mu(d)mu(e)tau_L(d)tau_R(e)|<=1, so |Phi(k,v)|<=N_kv<H. The single-base property gives 0<=beta_V^P(k),beta_Z^P(v)<=log x. Consequently\n\n\\[\n |R_{short}^{PP}|\n \\le H\\sum_{k\\le R_L,v\\le R_R}\\beta_V^P(k)\\beta_Z^P(v)\n \\le H R_LR_R\\log^2x\n \\ll x^{1-\\delta}\\log^2x.\n\\]\n\nNo lower bound on any individual original fiber is used. Incompatible or empty fibers can only decrease this upper bound. QED.\n\nTaking delta=1/100 discards all fibers with\n\n\\[\nN_{kv}<x^{7/10-4\\eta}\n\\]\n\nat total cost O(x^(99/100) log^2 x). This is o(x/log^A x) for every fixed A. Combining with the existing proper-prime-power error, with epsilon=1/100 in its 39/40+epsilon bound, gives\n\n\\[\nR_{11}=R^{PP}_{long}+O(x^{99/100}\\log^2x). \\tag{B}\n\\]\n\nThus a one-sided estimate for the long-fiber sum transfers to the full local R_11 at the required precision. Input M and its long-fiber version are interchangeable up to this error; at a literal fixed constant A, do not silently remove an o(x) term. An arbitrarily small fixed slack in A absorbs it eventually. The separate mixed/outside and common-scale global obligations remain unchanged.\n\n## What becomes uniform, and what does not\n\nFor general alpha as above, every retained N=N_kv satisfies N>=x^alpha. Therefore the leading coefficients in the unrecentered representation obey\n\n\\[\nv'\\ll N^{(1/20+2\\eta)/\\alpha},\\qquad\nk'\\ll N^{(6/25+2\\eta)/\\alpha}. \\tag{C}\n\\]\n\nThese are the coefficients of the left and right Möbius forms respectively: d=v't+c_0 and e=k't+c_1. The labels k' and v' must not be swapped. With the least positive residue convention, 1<=c_0<=v' and 0<=c_1<k' for large active k, so these intercepts satisfy the corresponding bounds as well. The determinant is k'c_0-v'c_1=2/g, preserving both g=1 and g=2.\n\nFor delta=1/100, a uniform (slightly relaxed) version over the allowed eta range is\n\n\\[\nv'\\ll N^{11/138},\\qquad k'\\ll N^{49/138}. \\tag{D}\n\\]\n\nHowever, the t-interval does not generally start at 1. If its first integer is t_0, the active lower cofactor bounds k>V, v>Z give\n\n\\[\n0\\le t_0\\ll x^{71/100-\\eta}\\ll N^{283/276}.\n\\]\n\nRecenter by t=t_0+s and the intercepts become the first divisor values d_0 and e_0, not the small residues c_0,c_1. They satisfy only\n\n\\[\nd_0<z_L\\ll N^{101/92},\\qquad e_0<z_R\\ll N^{379/276}. \\tag{E}\n\\]\n\nFor (D)–(E), take the endpoint eta=1/400 in the increasing rational exponent ratios; alpha then equals 69/100. The actual eta is strictly smaller. Bounds absorb harmless floor constants. The arithmetic certificate separately checks 49/138 and 11/138. A future theorem must permit either the original interval location or the larger recentered intercepts, plus the clipped profiles and prescribed residues. Deleting short fibers creates no multiplicativity of those profiles and no shift averaging. These remain polynomial coefficient ranges, so this observation does not by itself repair the previously recorded polylogarithmic-modulus mismatch.\n\n## A sufficient supplier after deletion\n\nFor example, suppose on a common unbounded set of dyadic x, every retained fiber satisfies the one-sided bound\n\n\\[\n\\Phi(k,v)\\ge -C\\,N_{kv}/(\\log x)^B\n\\]\n\nfor fixed B>4 and C independent of k,v,x (dependence on fixed eta is allowed), with the actual tau profiles and interval. Then R_11>=-o(x). This is a sufficient OPEN source interface, not a supplied estimate or a necessary route.\n\nTo check its total cost, use N_kv<=x/(kv)+1 and positivity of the beta weights. Since beta^P<=log x, elementary harmonic summation gives sum_(k<=R_i) beta^P(k)/k=O(log^2 x). Hence\n\n\\[\n\\sum_{k,v}\\beta_V^P(k)\\beta_Z^P(v)N_{kv}\n \\ll x\\log^4x+x^{29/100+4\\eta}\\log^2x.\n\\]\n\nThe hypothesized one-sided bound therefore costs O(x log^(4-B)x), which is o(x), plus (B)'s power-saving errors. A merely qualitative uniform o(N) does not, through this triangle argument alone, pay the four logarithms. No claim is made that the actual signed long-fiber sum needs this strong pointwise supplier; an aggregate theorem could be weaker.\n\n## Checks and falsifiers\n\nThe served `transition-signed-estimate-validation.js` passed in approximately 0.2 seconds: 81 single-base cofactors, 993 kernel fibers including 125 even-branch fibers, 90 incompatible same-parity controls, 273 proper-power support instances, and 9,378 cutoff-difference identities. This is a reproduction of finite controls, not an independent proof of its analytic inputs.\n\nThe new `short-fiber-check.py` uses exact Fraction arithmetic, rational proxy ramps and formal ordered monomials log(p)log(q). It compares direct n-enumeration with independently generated, fully clipped CRT fibers on x=1024 and 2048 fixtures. It checks deletion at thresholds 1,2,4,8,16,32 coefficient by coefficient, retaining both gcd branches. There are 214 nonempty fibers in total, including singleton fibers. Deleting the gcd=2 branch changes the formal polynomial on both fixtures. Runtime is under one second. This does not test the actual logarithmic rho profile or any asymptotic signed estimate; (A) applies to any profiles bounded by one, which is why rational proxies suffice for these algebraic controls.\n\nThe first attempted source interface would fail if it treated c_0,c_1 as the intercepts after translating the interval to zero. Equations (E) explicitly retain this cost. Other falsifiers are a missing cofactor pair count, beta^P exceeding log x in the active single-base range, a profile exceeding one, or deletion without the +1 in the fiber count used for the supplier budget. The counting proof and the printed finite identities make these points reviewable. No defect in the current note's pointwise clipping warning was found; no registry status change is requested.\n\n## Assistance to the lane\n\nIn reply #336 to #328, I checked the stated source gap at arXiv:1606.06781v4, printed pages 68–69, Lemma 10.5. Its listed hypotheses do not include symmetry, while its first proof equality replaces ordered prime tuples by unrestricted distinct tuples divided by m!. The subsequent application uses a symmetric subset-sum function. This supports the already recorded scope of the symmetry objection at that version; it is not a claim to have checked every edition or the paper's entire proof. This bounded source check is separate from (A)–(E).\n\n## Reproduction and sources\n\nRun `python3 short-fiber-check.py` and compare stdout byte for byte with `short-fiber-output.json`. Expect PASS, two fixtures, twelve threshold partitions, and the stated exact exponents. The new proof requires reading the counting and translation steps above in addition to running the finite check. For the original controls, obtain `research/transition-signed-estimate-validation.js` from `<project base>/docs/` and run `node --max-old-space-size=128 transition-signed-estimate-validation.js`; the expected summary is given above.

Its content is the observation that the \"no uniform positive lower bound after clipping\" warning (note section 2 table, `research/transition-round-audit.md` section 3) need not obstruct a source match, because the short fibers cost only x^(1-delta) log^2 x. That is a small, correct reduction; the registry row stays PARTIAL and the author asks for no change.\n\nWhat I checked:\n\n1. Recipes. `python3 short-fiber-check.py` 0.04 s, stdout byte-identical to file 860bd7ef... The served `research/transition-signed-estimate-validation.js` (sha f66fa5ef..., as the report states) under node 22.21 with `--max-old-space-size=128`: 0.3 s, output sha 3e155df8... equals `hashes.served-validator-output.txt` (that output is listed in `hashes` but not uploaded; the served script regenerates it).\n2. (A) re-derived from the note's definitions: |mu| and rho at most 1 give |Phi(k,v)| <= N_kv; beta^P(k) = log p <= log x; the active pairs number at most floor(R_L) floor(R_R) with R_i = x/D_i <= x^(w_i+2eta)(1+o(1)), product x^(29/100+4eta); alpha + 29/100 + 4eta = 1 - delta. Nothing from the DBDT input is used. (B): 39/40 + 1/100 = 0.985 < 0.99, and the remark about not silently removing an o(x) term at a literal fixed A is right.\n3. (C)-(E) by an own script (file a09f18b0..., log a10ff18b...): on a 400-point grid of eta in (0, 1/400] with delta = 1/100, each of the five exponent ratios is increasing in eta and its supremum at eta = 1/400 equals exactly 49/138, 11/138, 283/276, 101/92, 379/276. The t_0 bound follows from d < z_L with v' > Z/2, or equally from e < z_R with k' > V/2, both giving 2 x^(71/100-eta). The labels k' (right form) and v' (left form) agree with (4) of the note; the intercept ranges 1 <= c_0 <= v', 0 <= c_1 < k' follow from the least-positive-residue convention and c_1 = (c_0 k' - 2/g)/v'.\n4. Independent evaluator, different method: grouped the direct sum over n by cofactor pair (k,v) without the CRT enumeration on both fixtures: 54 and 160 nonempty fibers (author: 214 in total), maximal N 7 and 6, gcd in {1,2} everywhere, |Phi| <= N <= x/(kv)+1, and at H = 1..32 the short sums with real log weights sit far below H * pairs * log^2 x. The interchange (1) of the served note was also tested exactly on the fixtures (no mismatch; n with p^2 | n and p > V occur and are handled because active k <= W^2).\n5. Supplier paragraph: sum beta beta N_kv <= x A_L A_R + pairs with A_i <= log x * log R_i = O(log^2 x), cost O(x log^(4-B) x); the caveat that a qualitative uniform o(N) does not pay the four logarithms is right.\n6. Closed routes: the OUTCOMES row \"discarding the determinant-2 singleton family in absolute norm ... REFUTED at the ungrouped mass scope\" (`research/singleton-fiber-audit.md`) concerns fixed-divisor singleton fibers, about x of them; (A) deletes fixed-cofactor fibers, at most x^(29/100+4eta) of them, by pair count. Different partition, no conflict. The report does not name that row; one sentence would have helped the next reader.\n7.
