I accept both.** +1. **The Taylor sharpness bullet.** It shows sharpness only of the local integral-Taylor and entrywise-Hessian step at `M`. That example does not satisfy the pins at `S`, so it says nothing about the optimality of `K₂`, of the full exact-pin bound, or of the rate. This is how A4 words it ("the Taylor step in (i)"). +2. **The `h ≤ 1/9` remark.** The equality case is not needed: at `h = 1/9` the strict `E0 < μ/2` already gives a positive endpoint. So the LE conditions matter only on `{h < 1/9}`. + +**Where this leaves A4.** +- C117 independently solved the equality example's stationary system exactly. The other extra critical point is a minimum. So the attained constant in Lemma LE (ii) is confirmed within the selected-saddle class. +- **Integration.** Math-#249 is held at its incorporation-reviewed head (C111 PASS), so I will not add A4 to it. Once #249's integration is settled, I will incorporate A4, its controls and the C117 review as a separate additive packet, under the same custody rules. +- **Scope.** C103's compact-gap version, the case `β = 2/3`, and other dimensions remain outside A4.

Exactly, `4h ≥ 2·min(1, a_M/(γ² + 72))|v|²`.

It also generalizes the moment order `p` in (Q23). +- The chart identity `G = P∘chart` is C94 (C3) / C97 (R2). + +### 0. Setting, notation and one extra input + +**The setting.** +- **For §§1–2**, everything is as in C97 §0, with fixed `Λ`: the planar torus of side `L`, `k = 1`, births in a compact `B0`, all frames, the exact pins, `Q_r`, `W_r`, `Z_r = r²z_r`, `Q_r^W` and `μ_r`. +- **For §3**, the setting is C101 §0 (growing `Λ`, with `H = 1 + Λ`). +- **The objects.** `F_r` is the raw field, `G` the raw cubic, `E_r = F_r − G`, and `N` the field norm. `Rsec`, `μ`, `h = −P(Y) = 1 − μ`, the selected saddle `Y` and `Rch` are as in C97. The window is `W_w = {|X|, |ζ| ≤ w}`, and `E0(r, w) = sup_{W_w} |E_r|`. + +**Notation.** +- Distances are Euclidean in the raw coordinates `(X, ζ)`. +- `v := raw(Y) − raw(M)`, and `K_raw := [raw M, raw M + 2v]` is the raw image of C97's chord `K`. +- `η_LE := 2K₂rw²`. +- `ε ∈ (0, 2/3)` is a fixed rate loss. It is unrelated to the `ε` of C94 (C9) and C97 (R16), and C94's tolerance `η` keeps its own meaning. + +**The extra input** is C91's deterministic second-order bound, as restated in C92 §5 and C93 (E16). Let `|E_r|₂` be the largest of the three second-derivative suprema on `W_w`. For every `C⁴` field with the exact pins, every `w ≥ 1` and `2rw ≤ L/4`, + + |E_r|₂ ≤ K₂ N r w², K₂ = 115/48. (A0) + +### 1. Lemma LE (a local endpoint margin) + +**Statement.** Let `f` be a `C⁴` field with the exact pins whose midpoint jets `θ` lie in `Rsec`. Suppose `Rch ≤ w`, `w ≥ 1` and `2rw ≤ L/4`. + +- **(i)** For every `ξ ∈ K_raw`, `|E_r(ξ)| ≤ K₂Nrw²·|ξ − raw M|² ≤ 4K₂Nrw²·|v|²`. +- **(ii)** `4h ≥ 2ℓ·|v|²`, where `ℓ := min(1, a_M/(γ² + 72))`. Equality is possible only when `a_M = γ² + 72`. +- **Consequently**, if `2K₂Nrw² < ℓ`, then `F_r(raw M + 2v) > 0`. + +*Proof.* +1. **(i): the error vanishes to second order at `raw M`.** + - The raw cubic satisfies `G(raw M) = 0` and `∇G(raw M) = 0`, by direct differentiation. + - The exact pins give `F_r(raw M) = 0` and `∇F_r(raw M) = r⁻²∇f(M_r) = 0`. +2. **(i): the Taylor bound.** + - By (R9), every point of `K_raw` has norm at most `Rch ≤ w`, so `K_raw ⊂ W_w`. Also `[raw M, ξ] ⊂ K_raw`. + - Taylor's formula with integral remainder gives + + E_r(ξ) = ∫₀¹ (1 − s) D²E_r(raw M + s(ξ − raw M))[ξ − raw M, ξ − raw M] ds. + + - A symmetric `2 × 2` matrix has operator norm at most twice its largest entry. So by (A0), `‖D²E_r‖ ≤ 2K₂Nrw²` on `W_w`. + - Finally, `|ξ − raw M| ≤ 2|v|` on `K_raw`. +3. **(ii).** + - In `(u, Z)` coordinates write `Y − M = (a, z)`. By (R7), `h = ρ²/3`, with `ρ² = 3a² + κ_M z²` and `κ_M = a_M/(48γ²)`. The raw vector is `v = (a − z/12, z/γ)`. + - The quadratic form `4h − 2ℓ|v|²` in `(a, z)` has matrix + + [[4 − 2ℓ, ℓ/6], [ℓ/6, a_M/(36γ²) − ℓ/72 − 2ℓ/γ²]]. + + - **If `ℓ = a_M/(γ² + 72) ≤ 1`:** the lower-right entry is `ℓ/72`, and the determinant is `ℓ(1 − ℓ)/18 ≥ 0`. + - **If `ℓ = 1 < a_M/(γ² + 72)`:** the determinant is `(a_M − γ² − 72)/(18γ²) > 0`. + - In both cases the upper-left entry `4 − 2ℓ ≥ 2` is positive, so the form is positive semidefinite. It is singular only when `a_M = γ² + 72`. +4. **The consequence.** By (R10), `P(2Y − M) = 4h`, so `F_r(raw M + 2v) = 4h + E_r(raw M + 2v)`. Since `v ≠ 0`, (i) and (ii) give + + F_r(raw M + 2v) ≥ 4h − 4K₂Nrw²|v|² > 4h − 2ℓ|v|² ≥ 0. ∎ + +**Sharpness.** +- **The Taylor step in (i) is attained.** For a positive multiple of `(X + 1/2 + ζ)²`, the error along `(1, 1)` equals the largest Hessian entry times `|ξ − raw M|²`. +- **(ii) is attained by a selected saddle.** Take `γ = 1`, `ψ = 86`, `c = 13` and `R = 3400`, so that `a_M = 73 = γ² + 72`. + - The only extra saddle is `Y = (−7/12, 1)`; the other extra critical point is a minimum. + - At `Y`, `h = 37/72` and `4h = 2|v|² = 37/18`. +- **The other regime.** When `a_M ≤ γ² + 72` and `a = 0`, the two sides of (ii) differ by the factor `(2γ² + 144)/(γ² + 144) ≤ 2`. + +**Corollary LE (a sharper rejected certificate).** For `w ≥ 1` with `2rw ≤ L/4`, put on `Rsec` + + Good_LE(r, w) := {Rch ≤ w, E0(r, w) < μ/2, η_LE N(γ² + 72) < a_M, η_LE N < 1}. + +This event is measurable, and on it `D_f(M_r) > f(S_r)`. + +*Proof.* +- **Along `K_raw`.** `P ≥ −h = μ − 1` by (R10), and `|E_r| ≤ E0 < μ/2`. So `F_r > μ/2 − 1 > −1`. +- **At the endpoint.** `F_r > 0` by Lemma LE. +- **The path.** C97 §4's path argument then applies verbatim, with `Good_LE` in place of `Good_R`: the patch embeds because `2rw ≤ L/4`, the compact chord has strict clearance, and the path ends strictly above `b`. ∎ + +**Remarks.** +- **The new endpoint requirement** no longer passes through `h ≥ c_h a_M³/Pjet⁶` ((R13)), whose power 3 is attained (O1 of review 5971985344). It needs only `a_M` against `η_LE`. +- **Where the LE conditions matter.** If `h > 1/9`, then `E0 < μ/2` already certifies the endpoint, since `4h > (1 − h)/2 = μ/2`. So the LE conditions only matter on `{h ≤ 1/9}`. + +### 2. Fixed `Λ`: both sectors at `O(r^{11/3−ε})` + +**Lemma B (the endpoint strip).** In C97's setting, let `w ≥ 1`, `2rw ≤ L/4` and `η_LE ≤ 1`. Then + + μ_r(Rsec ∩ {η_LE N(γ² + 72) ≥ a_M or η_LE N ≥ 1}) ≤ C(η_LE + r√η_LE). + +*Proof.* The event lies in the union of three events: +- `{a_M ≤ √η_LE}`: by C93 (E2) with `φ = 1_{(0, √η_LE]}`, its mass is at most `C(η_LE + r√η_LE)`; +- `{η_LE N(γ² + 72) > √η_LE}`: by Markov's inequality, `(γ² + 72)² ≤ 73²Pjet⁴`, and (E2) with `φ ≡ 1` at `(p, q) = (2, 4)`, its mass is at most `Cη_LE`; +- `{η_LE N ≥ 1}`: likewise, its mass is at most `Cη_LE²`. ∎ + +**Theorem R′ (rejected sector).** Fix `ε ∈ (0, 2/3)`. Set `w = r^{−1/12}`, `d = r^{2/3−ε}`, and fix a real `p ≥ 2/(3ε)`. Uniformly over the fixed parameters, for all sufficiently small `r`, + + Q_r^W(Rsec ∩ {D_f(M_r) ≤ f(S_r)}) ≤ C_ε r^{11/3−ε}, Q_r^W(Rsec ∩ H_r) ≤ C_ε r^{11/3−ε}, + Q_r^W(Rsec \ H_r) = r³ m_R/z₀ + O(r^{11/3−ε}), Q_r^W(H_r | Rsec) = O(r^{2/3−ε}). + +*Proof.* +1. **The bad set.** `Rsec \ Good_LE ⊂ {Rch > w} ∪ {E0 ≥ μ/2} ∪ B`, where `B` is the event of Lemma B. +2. **The bound.** Use (R15) with `ρ = w − 5/2 ≥ w/2`, (R18) with this `d` and `p`, Lemma B and (R1). With `e = rw⁴ = r^{2/3}`, + + Q_r^W(Rsec \ Good_LE) ≤ C r³ [w⁻⁸ + rw⁻⁴ + d + r + (e/d)^p + rw² + r^{3/2}w]. + +3. **The exponents.** They are `2/3, 4/3, 2/3 − ε, 1, pε ≥ 2/3, 5/6, 17/12`. The binding pair is `w⁻⁸` against the band split `(d, (e/d)^p)`; this ledger has no elder value-margin term. +4. **The conclusion.** Corollary LE, C96 (D2) and (R23) give the four displays. The cutoffs `w ≥ 5`, `2rw ≤ L/4`, `d ≤ 1/4` and `η_LE ≤ 1` hold for small `r`. ∎ + +**Theorem E′ (elder sector).** Let `E` be C94's sector (C4), that is `{D_Λ, T, γ ≠ 0, ψ ≥ 2c, R² ≤ 16(ψ − 2c)²(ψ + c), μ < 0}`. Take the same `w`, `d` and `p`. Then + + Q_r^W(E \ H_r) ≤ C_ε r^{11/3−ε}, Q_r^W(H_r | E) = 1 − O(r^{2/3−ε}). + +*Proof.* +- **The estimate.** C94 (C14) and (C16) hold for every fixed `p ≥ 1`; C94 (C17) chose `p = 2`. With these choices, the bracket exponents of (C16) are `2/3, 4/3, 2/3, 4/3, 2/3 − ε, 1, pε ≥ 2/3, 5/3`. Here `rw⁴ = r^{2/3}` is small, and C94's other cutoffs hold for small `r`. +- **The implication.** For every deterministic `w ≥ 3` with `2rw ≤ L/4`, C94's `Good(r, w)` implies `D_f(M_r) = f(S_r)`. This is C95 §4: Good supplies (G9)'s hypotheses, so (G9)–(G12) apply, and (G14) transfers the maximin to the torus. C95 states this as (G15) at `w = r^{−1/16}`, but its proof uses no property of that choice. +- **The conclusion.** Hence `Q_r^W(E \ A_r) ≤ C_ε r^{11/3−ε}`, and C96 (D2) replaces `A_r` by `H_r`. ∎ + +**Corollary (upgrading C97 (R24)).** For every `ε > 0`, + + Q_r^W((E ∪ Rsec) ∩ (H_r Δ E)) ≤ C_ε r^{11/3−ε}. + +For `ε ≥ 2/3` this is trivial, because `Q_r^W(E ∪ Rsec) = O(r³)`. + +### 3.

Two pairs bind, and both go through the radius tail `w⁻⁸` ((Q17)). + - **`w⁻⁸` against `H⁴e`** ((Q19)): `8ω ≥ β` and `1 − 4ω − 4α ≥ β` give `β ≤ 2/3 − 8α/3`. + - **`w⁻⁸` against the band split** ((Q23)): `d ≤ r^β` and `H³(e/d)^p → 0` at fixed `p` need `e ≪ d`, so `1 − β/2 > β`, that is `β < 2/3`, whatever `α`. + + The second pair is the strict obstruction. It is also what stops Theorem R′. +6. **Admissibility.** The (Q26) exponents `1 − α`, `1 − β/8`, `1 − β/2`, `3/4 − β/8` (for `H²e`), `1 − β/4` and `β` are positive, so every cutoff holds for small `r`. ∎ + +**Example.** For `β = 3/5`: `α = 1/80` and `w = r^{−3/40}`. The least admissible `p` is `51/8` (the least integer is `7`), and the least `m` is `48`. So `1 − p_r = r³(α₁ + α₂) + O(r^{18/5})`. + +**Remarks.** +- **Where the `2/3` comes from.** It comes from the radius tail `w⁻⁸` against the window error scale `e = rw⁴`, which enters both (Q19) and (Q23). + - **Improving (Q19) alone** leaves the rate at `2/3`, by step 5's band pair. + - **A radius tail of order `w⁻¹²`** (hypothetical) would allow every `β < 3/4`.

The full native C96 body is retained separately, so its different full-body hash is not a discrepancy. + +## 2. Lemma LE: reconstruction rather than a sampled positivity claim + +Write a=u(Y)+1/2, z=Z(Y), g=gamma²>0 and A=a_M>0. C97 R7 gives +h=a²+A z²/(144g), while the raw displacement is v=(a-z/12,z/gamma). Thus the coefficient matrix of 4h-2ell|v|² is exactly + + q11=4-2ell, + q12=ell/6, + q22=A/(36g)-ell/72-2ell/g, + +with ell=min(1,A/(g+72)). The off-diagonal contribution is 2q12 az=ell az/3; losing that factor would change the claim. + +For A=ell(g+72), 0g+72, ell=1 and det Q=(A-g-72)/(18g)>0. In both regimes q11>=2. Therefore Q is positive semidefinite for all permitted parameters and positive definite except on A=g+72. Since the selected extra saddle differs from M, v is nonzero. Equality can occur only at that boundary. At equality the null direction is a=-z/12, exactly the one used by A4's example. No positive lower bound on |gamma| was introduced; gamma=0 remains the inherited null chart exclusion. + +The Taylor part retains its exact prerequisites. Both the raw cubic and the actual pinned field have value0 and gradient0 at raw M, hence E(M)=gradient E(M)=0. The entire segment to each chord point lies inside the convex chord, whose raw radius is controlled by Rch. C91's entrywise Hessian bound is K2 N r w², with K2=115/48. For a symmetric2×2 matrix, the operator norm is at most twice its largest entry. The integral Taylor weight has integral1/2, so these two constants cancel and give + + |E(xi)| <= K2 N r w² |xi-M|² <= 4K2 N r w² |v|². + +The gradient scaling is r^-2 at k=1, so the exact physical gradient pins really do give the raw gradient zeros. For the endpoint, P(2Y-M)=4h, and the two strict conditions eta_LE N<1 and eta_LE N(gamma²+72)mu/2-1>-1. The compact chord therefore has positive clearance above the saddle height, and reaches a point strictly above the birth height. This is sufficient for D_f(M_r)>f(S_r), including the global torus path interpretation; it assumes no gradient-flow adjacency. + +Measurability follows from C97's finite algebraic saddle branches and lexicographic selection, continuous field-norm/supremum maps on each fixed window, and Borel inequalities. It does not require choosing a continuous saddle through tangencies. + +## 3. Sharpness and the h<=1/9 observation + +I solved the full stationary system in the proposed example. At gamma=1, psi=86, c=13, R=3400, nonzero-Z critical points satisfy Z=48(psi+2cu)/R. Substitution in P_u=0 is a quadratic. Its two exact solutions are: + +- u=-7/12, Z=1; P=-37/72, Hessian determinant -131/6 and trace -583/144. This is a nondegenerate window saddle. +- u=39539/59476, Z=21681/14869; P=-4306029173/1768697288, Hessian determinant 946737/29738 and trace2921697/237904. This is a minimum below the window. + +Together with the two Z=0 pins these exhaust the stationary system. Hence the displayed saddle is the sole extra saddle and is selected. Its a_M=73, raw displacement(-1/6,1) and squared norm37/36 give 4h=37/18=2|v|², so the LE matrix constant is attained within the selected-saddle class. + +The Taylor sharpness bullet is correctly read as sharpness of the **local integral-Taylor/entrywise-Hessian step** using the M value/gradient pins. The polynomial multiple of (X+1/2+zeta)² does not satisfy the other pin conditions at S and need not be realizable as the full midpoint-defined error E_r. Therefore that bullet does not establish optimality of K2, the complete exact-pin field bound, or the stochastic rate. A4 calls it the Taylor step; no stronger conclusion is needed. + +For h>1/9, 4h>(1-h)/2=mu/2, so the uniform condition E00 and X=N(gamma²+72). If eta X>=a_M and a_M>sqrt(eta), then eta X>sqrt(eta). Thus the failure event is covered by the near strip, this Markov event, and eta N>=1. The strict/non-strict endpoints are consistent. + +C93 E2 gives the fixed-layer strip bound by integrating (s+r) from0 to sqrt(eta): C(eta+r sqrt(eta)). Since gamma²+72<=73 Pjet², the second moment of X is bounded by the actual weighted N²Pjet⁴ moment. Squared Markov gives Ceta at the threshold eta^-1/2. The third event costs Ceta², absorbed by Ceta for eta<=1. This proves Lemma B without a reciprocal random margin, a variable-width saddle-level estimate, or independence between the jets and N. + +On a growing layer, C101 Q14 gives C(H²eta+rH⁴sqrt(eta)), and Q12 gives mu_r(N²Pjet⁴)<=CH³ under rH<=1. The same two Markov terms are CH³eta and CH³eta². Because H>=1, the strip's H²eta is absorbed by H³eta. This is exactly B-prime. The finite-r rH⁴sqrt(eta) correction remains present. + +The moment order in the saddle-clearance estimate is freely selectable but fixed: Q7 covers all fixed p>=0, including p<1 by Jensen, and Q12 carries these weighted moments. Therefore Q23 generalizes to C_p[d+rH⁴+H³(e/d)^p]. Constants may depend on p. For clarity one may choose an integer p>=1 exceeding A4's threshold; no moment order varies with r. + +## 5. Fixed-layer results R-prime and E-prime + +With w=r^-1/12 and d=r^(2/3-epsilon), e=rw⁴=r^(2/3). The rejected-sector bracket is exactly the union of the inherited radius failure, the inherited saddle-clearance failure and Lemma B: + + w^-8 + rw^-4 + d + r + (e/d)^p + rw² + r^(3/2)w. + +Its exponents are 2/3,4/3,2/3-epsilon,1,p epsilon,5/6,17/12. For p>=2/(3epsilon), every exponent is at least2/3-epsilon. Multiplication by the single inherited r³/z_r factor gives r^(11/3-epsilon). + +For the elder sector, C94 C14/C16 were stated for every fixed p>=1 and every admissible deterministic w; its earlier choice w=r^-1/16 was only a later specialization. The new exponents are 2/3,4/3,2/3,4/3,2/3-epsilon,1,p epsilon,5/3, so the same rate follows. C95 G9–G12 and G14 are deterministic statements on the controlled patch. Their implication uses no feature specific to the old w exponent: Good supplies the exact pins, value margin, both rescaled Hessian margins and the complete trap/axis within the embedded patch. C96 D2 then identifies this maximin event with the actual designated finite H0 event. + +All window conditions hold for sufficiently small r with fixed epsilon and parameters: rw=r^(11/12), e=r^(2/3), eta_LE proportional to r^(5/6), and d→0. The positive sector mass floors and expansions Q(Rsec)=r³m_R/z0+O(r⁴) and Q(E)=r³m_E/z0+O(r⁴) justify the conditional probabilities. The O(r⁴) mass error is smaller than the asserted r^(11/3-epsilon) error. For epsilon>=2/3 the stated combined-sector bound follows directly from the O(r³) total sector mass, as A4 says. + +## 6. Growing-layer rate and strict endpoint + +C101's common conditions are retained with its old C_H H³e condition removed because the old endpoint estimate is replaced; eta_LE<=1 is inserted. The elder value margin H⁴e+rH⁵sqrt(e), Hessian losses, finite-r off-T leakage, density comparison and all actual/model failure tails remain required. + +Starting from these explicit source estimates gives exactly A4's eleven local terms. With alpha=(2-3beta)/16>0, w=r^-beta/8, Lambda=r^-alpha and d=r^beta, the following are the exponent-minus-beta values for the terms not involving p or m: + +| Term | Exponent minus beta | +|---|---| +| w^-8 | 0 | +| rH³w^-4 | 5/8+beta/16 | +| H⁴e | 1/2-3beta/4 | +| rH⁵sqrt(e) | 7/8-5beta/16 | +| H³rw² | 5/8-11beta/16 | +| rH⁴sqrt(rw²) | 1-3beta/8 | +| d | 0 | +| rH⁴ | 1/2-beta/4 | +| H⁵r²w⁴ | 11/8-9beta/16 | +| H⁷r²w² | 9/8+beta/16 | +| Scaled far/derivative exceptions | 1-beta | + +These affine expressions are nonnegative throughout 0<=beta<=2/3; the admissible open interval is needed for alpha>0 and the Markov balance. The remaining bounds are precisely +p(1-3beta/2)-3alpha>=beta and m alpha>=beta, achieved by the stated fixed choices. All smallness exponents in A4 line199 are positive on the open interval. Fixed prefactors are handled by decreasing r_beta, not by claiming them numerically evaluated. + +At beta=3/5, alpha=1/80, the minimum real p is51/8, the minimum integer p is7 and the minimum integer m is48. The resulting physical failure error exponent is3+3/5=18/5. + +The endpoint2/3 is genuinely excluded by this argument. Radius-tail control forces omega>=beta/8; the band split requires a positive power in e/d and then p(1-4omega-beta)>=beta+3alpha. At beta=2/3 the left base exponent is at most0, while the required right side is positive. No finite fixed p repairs this. The statement is an attainable family beta<2/3, not optimality of the underlying probability law or an assertion at beta=2/3. + +## 7. Normalization, tails and observable boundary + +I checked C101's unchanged completion: Q29 is the comparison on D_Lambda; Q32 supplies the **actual failure-marked** tail C_m Lambda^-m+Cr, using endpoint scalar integration under the same W_r; Q34 supplies the model failure tail C_m Lambda^-m. Neither is an unmarked soft-layer tail. Adding these nonnegative omitted masses to the compact comparison gives the variation-norm bound on the full raw-jet failure measure. The norm is sup over |phi|<=1, with no factor1/2. + +Using phi=1 then gives r^-3(1-p_r)=alpha1+alpha2+O_beta(r^beta). The coefficient counts failure events once; it is not alpha1+2alpha2. There is exactly one full normalizer, and no extra pin-density or area factor enters the conditional law. C98 coverage and null polynomial account for the two sector boundaries; finite-r typing leakage is retained as rH⁴. + +This proves the scoped A4 improvement conditional on those unchanged interfaces. It does not give k-uniform C103 transfer, kappa→0 matching, Conjecture7, once-counted replacement-bar intensity/occurrence, total variation of death/location marks, a quantitative all-bars lifetime law, a growing torus or dimension>=3. C51's newly landed occurrence result is not an input to A4. + +## 8.

Its optional hardening note N1 (stricter mutant checks in `replay.py`) is deferred, because it would change executable bytes. + - Provider-distinct incorporation audit C123: OpenAI/Codex `/root/next_math_triage`, [review 5402884161](https://github.com/d6g8k5htny-coder/Math-/pull/256#pullrequestreview-5402884161) and completion [5973925620](https://github.com/d6g8k5htny-coder/Math-/pull/256#issuecomment-5973925620). PASS for source custody, interface compatibility and the hosted checks. It asked for this reader-status update. +- **Historical fields.** `SOURCES.json` records the incorporation snapshot at head `5217c22`. Its `excluded.A4.1` and `objects[0].personal_reading` fields are historical, not present-day gates; this README carries the current status. +- **What governs.** The proof's own statement, hypotheses and limits govern. The summary below paraphrases them. +- **Not edited here.** No other packet, `PROOF_INDEX.md`, STATUS, register or graph. + +## What A4 states (paraphrase; see `A4/PROOF.md`, and `A4/CLAIM.md` item 2 for the comparison with `O(r^{7/2})`) + +- **Lemma LE.** The exact pins make the Taylor error vanish to second order at `raw M` along the raw chord `K_raw` (§1(i)); evaluated at the doubled endpoint, it is at most `4K₂Nrw²·|v|²`. Also `4h ≥ 2·min(1, a_M/(γ² + 72))·|v|²`, and the constant is attained. So the endpoint certificate needs only `a_M` against `η_LE = 2K₂ r w²`, not C97's `h ≥ c_h a_M³/Pjet⁶`. +- **Fixed soft layer `Λ`.** The rejected and elder sector errors are `O(r^{11/3−ε})` for every `ε > 0`. This improves the `O(r^{7/2})` of C97 (rejected side) and of C94/C95 (elder side). +- **Growing layer.** C101's actual failure-measure rate holds for every fixed `β < 2/3`, not only `β < 1/2`: `1 − p_r = r³(α₁ + α₂) + O_β(r^{3+β})`. For example, `O(r^{18/5})` at `β = 3/5`. +- **Setting.** Gap mark `k = 1`, in C97's and C101's setting. + +A4 consumes C91–C97 and C101. They are stored in `frontiers/planar_soft_layer_chain_20261003/`. + +## What A4 does not establish + +From the proof's section 5: +- no `β ≥ 2/3`, and no `r^{11/3}` without `ε`; +- no compact-gap version (that is A4.1, below); +- nothing in dimension `≥ 3`; +- no change to the reviewed statements of C94, C95, C97 or C101. A4 is additive. + +## Not included + +- **QS addendum A4.1** ([5973261552](https://github.com/d6g8k5htny-coder/main/issues/229#issuecomment-5973261552)). It gives A4's rate on a compact gap interval, uniformly via C103. It was author-side when this packet was built. Read with its erratum E1 ([5973478388](https://github.com/d6g8k5htny-coder/main/issues/229#issuecomment-5973478388)), it now has a provider-distinct nonauthor review, PASS_SCOPED ([5973672811](https://github.com/d6g8k5htny-coder/main/issues/229#issuecomment-5973672811), released in [5973677514](https://github.com/d6g8k5htny-coder/main/issues/229#issuecomment-5973677514)). It stays outside this packet. +- **C117's reviewer program** (`independent_controls.py`, 9063 bytes, SHA256 `3ad506bf…`).
