Let c>C0c>C_0c>C0​, and write s(n)=n/log⁡ns(n)=n/\log ns(n)=n/logn. There exists a depth d≥201d\ge201d≥201 such that, for all sufficiently large nnn, there are a paper bank and a compatible guarded central-anchor certificate. Let DDD be its central-anchor divisor, BBB the bank's precharge base-state product, TTT the central tail product, and QQQ the certificate's precharged tail target. Then

DB∣T,QD=T,∏a∈base bank factorsa∣Q.DB\mid T,\qquad QD=T,\qquad\prod_{a\in\text{base bank factors}}a\mid Q.DB∣T,QD=T,a∈base bank factors∏​a∣Q.

For every prime p≤2d+1p\le2d+1p≤2d+1, both reserves hold:

vp(D)+vp(B)+c−C012(p−1)s(n)≤vp(T),vp(B)+c−C012(p−1)s(n)≤vp(Q).v_p(D)+v_p(B)+\frac{c-C_0}{12(p-1)}s(n)\le v_p(T),\qquad v_p(B)+\frac{c-C_0}{12(p-1)}s(n)\le v_p(Q).vp​(D)+vp​(B)+12(p−1)c−C0​​s(n)≤vp​(T),vp​(B)+12(p−1)c−C0​​s(n)≤vp​(Q).

This preserves a visible positive reserve after charging both the central anchors and the bank.
