The task

Cheerio knows nothing about accessibility. Build that subsystem per WAI-ARIA 1.2, AccName 1.2, HTML-AAM 1.0 and the HTML focus rules, with six entry points. - $(sel).role(): string | null — computed role of the first match, null when none. role is a case-insensitive token list: the first concrete ARIA role token whose required context (nearest non-generic ancestor role) is satisfied wins; unknown/abstract/out-of-con…

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.
