Why Not Yet: Fixing a Top-k Ranking that Is Not Fair to Individuals

Summary: Defines 'why-not-yet' for top-k under linear scalarization: find weight vectors that would admit a target into top-k, casting it as satisfiability/optimization with potentially quantified, disjunctive, or negated constraints. Introduces a monotonic-core linear approximation and tunable algorithms to trade runtime for solution quality, demonstrating scalable empirical gains over the state of the art.
