Fix h,Jh,J, k≤Jk\le J, a selected global output qq, and a prefix list. Let N=((J−k)2h(J−k)h)N=\binom{(J-k)2h}{(J-k)h}. Assume the selected cover and occurrence data are retained, and original arrays have correct physical buckets for the unshifted left and shifted right residue keys modulo modulus⁡(h,J)\operatorname{modulus}(h,J). Reserve successive candidate, left-mask, right-mask, and endpoint/flag regions before bit and arithmetic scratch. Require the terminal space and word budgets, space fitting in a word, word bounds for original values, target sums and NLNRN_LN_R, and depth d+N+512hJ+9d+N+512hJ+9. The fixed program returns r∈{0,1}r\in\{0,1\} satisfying

r=1  ⟺  ∃ terminal candidate with both allowed flags and selected physical positions i,j: Rj−Li−a=0.r=1\iff\exists\text{ terminal candidate with both allowed flags and selected physical positions }i,j:\ R_j-L_i-a=0.

It computes the required masks itself, meets the terminal time budget, and preserves memory below the candidate-mask base.

This supplies the complete terminal operation from retained cover and source data.
