\caption{Representativeness of \textbf{LintEval-Lite} (498 instances) against the full \textbf{LintEval} benchmark (13,061 instances). The Lite split preserves the language, alert-category, and alert-density distributions of the full benchmark. All expensive model evaluations in the paper are conducted on Lite.}
