For any natural number $h$ , put $L=512h$ , $v=\binom{L}{h}$ , and $M=2^{600000(h+1)^2}$ . Let $p$ be the construction's selected local prime, $c=\lceil4(p+v)/p\rceil$ its bucket cap, $R=p^{2L}$ the candidate-row count, and $T=320(2h+1)(\lfloor\log_2(p^2)\rfloor+1)$ the schedule length. Then

\max\left\{1,L+1,v+1,p+1,c+1,R+1,T+1,p^{2L+1}+1,2^{L+1}+1\right\}\le M.

These simultaneous bounds cover the local-cover tables, schedule, candidate decoding, and mask arithmetic. They provide a single magnitude parameter for subsequent polynomial resource estimates.
