Fix a positive permitted-mesh constant cmeshc_{\rm mesh}cmesh​, physical intervals III with endpoints between 111 and U≥1U\ge1U≥1, natural guard budgets Cprom,CbankC_{\rm prom},C_{\rm bank}Cprom​,Cbank​, and a guard ledger at every integer nnn. There exist a tolerance τ>0\tau>0τ>0 and a prime cutoff W0W_0W0​ with the following property. For every W≥W0W\ge W_0W≥W0​, finite nonempty head-pattern family supported exactly on the primes at most WWW, nonnegative constants Ctarget,Cinitial,Cmass,Cfixed,CactiveC_{\rm target},C_{\rm initial},C_{\rm mass},C_{\rm fixed},C_{\rm active}Ctarget​,Cinitial​,Cmass​,Cfixed​,Cactive​, and positive cell-mass margin mmm, there exist a positive parameter radius aaa and Cpost≥0C_{\rm post}\ge0Cpost​≥0, chosen before the mesh. For every permitted regular relative mesh of width δ+η≤τ\delta+\eta\le\tauδ+η≤τ with δ>0\delta>0δ>0, all sufficiently large nnn have the following property.

Every bridge built from the canonical surviving cells at (n,W)(n,W)(n,W), with separated physical intervals, nonempty surviving cells, canonical scale-separated partition, bridge width δ+η\delta+\etaδ+η, and barycentric baseline of cell margin at least mmm, admits a physically centered fixed-partition fit. Here the band displacement Δ\DeltaΔ satisfies the CtargetC_{\rm target}Ctarget​ envelopes; monitored primes are primes at most y(n)y(n)y(n); N≥0N\ge0N≥0, active mass q≤CmassNq\le C_{\rm mass}Nq≤Cmass​N, and each initial marked error is at most CinitialN/(pL)C_{\rm initial}N/(pL)Cinitial​N/(pL). The finite frozen layer has ambient weights in [0,1][0,1][0,1], frozen and active sample weights bounded respectively by Cfixed/LC_{\rm fixed}/LCfixed​/L and Cactive/LC_{\rm active}/LCactive​/L, separated head patterns, and integer quota equal to frozen mass plus qqq. In the source's notation, the conclusion is

B has a physically centered fixed-partition fit (Δ,a,P,t,N,Cpost;frozen layer, quota).B\text{ has a physically centered fixed-partition fit }(\Delta,a,\mathcal P,t,N,C_{\rm post};\text{frozen layer, quota}).B has a physically centered fixed-partition fit (Δ,a,P,t,N,Cpost​;frozen layer, quota).

The fit is the source's bundled path certificate, including its displacement, invariance, marked-moment and feasibility requirements. The order of choices makes the analytic constants uniform before the eventual sample size.

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, with reuse governed by our licensing terms.
