Fix W,K∈NW,K\in\mathbb NW,K∈N, c>0c>0c>0, 1<r0<3/21<r_0<3/21<r0​<3/2 and 0<δ<1/180<\delta<1/180<δ<1/18 with 80CMδ<g=dW(2−r0)80C_M\delta<g=d_W(2-r_0)80CM​δ<g=dW​(2−r0​). Set h=hn(c)h=h_n(c)h=hn​(c) and use the canonical cutoff X0(n,δ)X_0(n,\delta)X0​(n,δ) and density g/16g/16g/16. Eventually, for every 0<v≤u≤y(n)0<v\le u\le y(n)0<v≤u≤y(n) with u/v≤r0u/v\le r_0u/v≤r0​, the broad multiplier interval is ordered and

⌊n/v⌋≤⌊BroadUpper(n,K,h)/u⌋,Leff+Enat+4+4Msharp(n)≤Lcandidate.\lfloor n/v\rfloor\le\lfloor\mathrm{BroadUpper}(n,K,h)/u\rfloor,\qquad L_{\rm eff}+E_{\rm nat}+4+4M_{\rm sharp}(n)\le L_{\rm candidate}.⌊n/v⌋≤⌊BroadUpper(n,K,h)/u⌋,Leff​+Enat​+4+4Msharp​(n)≤Lcandidate​.

Here LeffL_{\rm eff}Leff​ is the effective lower cardinality at density g/16g/16g/16 and endpoint vvv, EnatE_{\rm nat}Enat​ is the canonical exceptional natural upper bound for (n,K,h,X0,y,u,v)(n,K,h,X_0,y,u,v)(n,K,h,X0​,y,u,v), and LcandidateL_{\rm candidate}Lcandidate​ is the rough-head candidate lower floor.

This discharges the arithmetic comparison required for the canonical clean-list bridge.

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.
