For input size $n$ , let $m=\lfloor\log_2n\rfloor$ , $h$ be the prescribed micro-half, $P$ the prime-window scale, and $M$ the maximum modulus. Use the common resource scale $\Sigma_n=2^{2048(m+1)}+2^{5000000(h+1)^2}+M+P+n+100$ .

Let $f\in\mathbb N$ be the initial free-memory address. Form the wanted-stage layout with the prescribed radix, micro-half, block count, and incidence capacity. The incidence capacity is the band size times the candidate-band count. If $s(f,n)$ denotes the source-storage base after the wanted records and pair storage, then

s(f,n)\le f+100\Sigma_n^5.

The bound holds for every $f,n\in\mathbb N$ .

This bounds the address offset consumed before the encoded source data begin, allowing the later source workspace to be placed within one common allocation.
