Write S,Ω,ΔS,\Omega,\Delta for machine space, word magnitude, and depth limits. Let k≤Jk\le J, W=512hJW=512hJ, V=512h(J−k)V=512h(J-k), and

N=((512h2h)(2hh))k.N=\left(\binom{512h}{2h}\binom{2h}h\right)^k.

Let f,gf,g be integer set functions on WW coordinates, bounded by B0,D0B_0,D_0 through cutoff c≤Wc\le W, with their complete source transforms stored. Let b≤Vb\le V and kh+b≤ckh+b\le c. Enumerate all NN ordered pairs (Ai,Bi)(A_i,B_i) whose restrictions to each of the first kk blocks are disjoint hh-element sets. Each prefix has cardinality khkh.

Assume the specified ordered mask-enumeration, radix-stage, pointer, box, and scratch regions, the address and radix-key bounds, 23VB0D0≤Ω2^{3V}B_0D_0\le\Omega, S≤ΩS\le\Omega, and depth bounds d+512h+k+5≤Δd+512h+k+5\le\Delta and d+W+14≤Δd+W+14\le\Delta. The routine returns the left prefix-array header HH and stores

ν(H)=N,ν(p+i)=q+i(V+1)∑j≤b(Vj).\nu(H)=N,\qquad \nu(p+i)=q+i(V+1)\sum_{j\le b}\binom Vj.

It retains both prefix-mask arrays and every box-transform stage of the signed leaf function formed from Ai,BiA_i,B_i, offset 512hk512hk, and source stage VV. Source transforms and cells before enumeration output remain unchanged. The stated prefix-catalog time bound holds.

This precomputes suffix data for every prefix pair at a fixed level.
