-// Audit fixture — peer-plugin parity for `ember/template-require-iframe-title`.
-// 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 —".
+// Audit fixture — translates peer-plugin test cases into assertions against
+// our rule (`ember/template-require-iframe-title`). 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`.
+//
+// Peers covered: jsx-a11y/iframe-has-title,
+// vuejs-accessibility/iframe-has-title, lit-a11y/iframe-title.
