An alternating fixpoint tailored to magic programs

Summary: Identifies mismatch between well-founded models of Datalog programs with negation (possibly non-2-valued) and their magic-set rewritings using common left-to-right SIPS, causing query-driven WF model divergence. Proposes a novel, natural tailoring of Van Gelder's alternating fixpoint to magic programs to restore agreement and enable correct query-directed evaluation.
