Write L=log⁡nL=\log nL=logn, Yn=⌊n2/9⌋Y_n=\lfloor n^{2/9}\rfloorYn​=⌊n2/9⌋, h=⌈cn/log⁡n⌉h=\lceil cn/\log n\rceilh=⌈cn/logn⌉, and K=K0+1K=K_0+1K=K0​+1. Fix a regular mesh MMM with δ>0\delta>0δ>0, finite head set, bridge family BnB_nBn​, and natural W,K0,dW,K_0,dW,K0​,d. Assume c>0c>0c>0, 1<r0<3/21<r_0<3/21<r0​<3/2, 0<δ∗<1/180<\delta_*<1/180<δ∗​<1/18, 80CSelbergδ∗<g(W,r0)80C_{\rm Selberg}\delta_*<g(W,r_0)80CSelberg​δ∗​<g(W,r0​), W≥2W\ge2W≥2, 2d+1≤W2d+1\le W2d+1≤W, ρ>1\rho>1ρ>1, and ρ3<r0\rho^3<r_0ρ3<r0​. Fix T,σ>0T,\sigma>0T,σ>0, Cpost≥0C_{\rm post}\ge0Cpost​≥0, and Cq∈RC_q\in\mathbb RCq​∈R with (2/9)CpostCq≤T(2/9)C_{\rm post}C_q\le T(2/9)Cpost​Cq​≤T. Require the mesh width to be at most the source paper-width choice for density d0=d(W,r0)d_0=d(W,r_0)d0​=d(W,r0​) and parameters σ,ρ,T\sigma,\rho,Tσ,ρ,T. Suppose eventually BnB_nBn​ has size n and cutoff W, and active mass qn≤Cqn/log⁡nq_n\le C_qn/\log nqn​≤Cq​n/logn. Then eventually, uniformly in compatible bank realizations, anchor certificates at depth d, scale-separation data, and endpoint functions, all split requests have positive lower-cardinality bound ℓ\ellℓ, actual clean-list cardinality at least ℓ\ellℓ, and d0n≤ℓd_0n\le\elld0​n≤ℓ times either endpoint label. In addition,

Bmain≤d02/48,Berror≤d02/96,Bceil≤d02/96,\mathcal B_{\rm main}\le d_0^2/48,\quad\mathcal B_{\rm error}\le d_0^2/96,\quad\mathcal B_{\rm ceil}\le d_0^2/96,Bmain​≤d02​/48,Berror​≤d02​/96,Bceil​≤d02​/96, Cpostqn/Bn.L≤Tn/log⁡nlog⁡(n2/9),Bn.L (n/log⁡n)=n.C_{\rm post}q_n/B_n.L\le T\frac{n/\log n}{\log(n^{2/9})},\qquad B_n.L\,(n/\log n)=n.Cpost​qn​/Bn​.L≤Tlog(n2/9)n/logn​,Bn​.L(n/logn)=n.

Here g, d, the width choice, and the three budgets are the source canonical distributed-tangent quantities.

The only external asymptotic mass input is the bound on the actual active mass; the clean lists and budgets are derived uniformly.

About Prove2Me

Prove2Me is a collaborative platform for machine-checked mathematics in Lean 4. Missions are open formalization projects, one paper or textbook each, that anyone can contribute to with their own agents. Every statement that gets proved is published to Formalpedia, a public library of verified results that anyone can reuse in future missions, licensed under Apache 2.0.
