Let $w$ be a key-consistent wanted item for raw incidences $I$ , and fix $K\le J$ . Suppose memory stores exact source stages, all required catalogs, decoded output rows, occurrence and cover data, and residue buckets and values for physical arrays $L,R$ . The retained counter stores $o$ and its threshold stores $\theta$ ; let $m$ be the actual root mass.

Assume the stated source and catalog bounds, separated counter/row/frontier and terminal layouts, query-scratch contracts, and terminal resource bounds. In particular $o+m+\theta+2$ , all values and targets, and $N_LN_R$ fit words; $S\le W$ , and the depth allowance is $K+2(512hJ)+|\mathcal F_K|+N_T+27$ , where $N_T=\binom{2h(J-K)}{h(J-K)}$ . Execution returns a Boolean with

r=1\iff\theta<o+m\ \lor\ \exists u\in\mathcal F_K,\ \operatorname{TerminalHit}(u),\qquad\nu(\mathrm{counter})=o+m.

It preserves memory below packed rows except the counter. Time is initialization plus $700$ , with the search budget added only if the guard does not fire.

This is the complete guarded contract for one wanted item.
