-// Audit fixture — translated test cases from peer plugins to measure
-// behavioral parity of `ember/template-no-aria-hidden-on-focusable` against
-// jsx-a11y/no-aria-hidden-on-focusable and
-// vuejs-accessibility/no-aria-hidden-on-focusable.
+// Audit fixture — translates peer-plugin test cases into assertions against
+// our rule. Runs as part of the default Vitest suite (via the `tests/**/*.js`
+// include glob) and serves double-duty: (1) auditable record of peer-parity
+// divergences, (2) regression coverage pinning CURRENT behavior. Each case
+// encodes what OUR rule does today; divergences from upstream plugins are
+// annotated as `DIVERGENCE —`. Peer-only constructs that can't be translated
+// to Ember templates (JSX spread props, Vue v-bind, Angular `$event`,
+// undefined-handler expression analysis) are marked `AUDIT-SKIP`.
 //
-// These tests are NOT part of the main suite and do not run in CI. They encode
-// the CURRENT behavior of our rule so that running this file reports pass.
-// Each divergence from an upstream plugin is annotated as "DIVERGENCE —".
+// Peers covered: jsx-a11y/no-aria-hidden-on-focusable,
+// vuejs-accessibility/no-aria-hidden-on-focusable.
