-// Audit fixture — translated test cases from jsx-a11y to measure behavioral

-// jsx-a11y/no-noninteractive-tabindex.
+// Audit fixture — translates peer-plugin test cases into assertions against
+// our rule (`ember/template-no-noninteractive-tabindex`). 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 jsx-a11y is annotated as "DIVERGENCE —".
+// Peer covered: jsx-a11y/no-noninteractive-tabindex.
