dl-saturate! is now semi-naive: tracks a per-relation delta dict, and on each iteration walks every positive body-literal position, substituting the delta of its relation while joining the rest against the previous-iteration DB. Candidates are collected before mutating the DB so the "full" sides see a consistent snapshot. Rules with no positive body literal (e.g. (p X) :- (= X 5).) fall back to a one-shot naive pass via dl-collect-rule-candidates. dl-saturate-naive! retained as the reference implementation; 8 differential tests compare per-relation tuple counts on every recursive program. Switched dl-tuple-member? to indexed iteration instead of recursive rest (eliminates per-step list copy). Larger chains under bundled conformance trip O(n) membership × CPU sharing — added a Blocker to swap relations to hash-set membership.
