+## Escape hatches
+
+An element opts out of this rule's handler-on-non-interactive check in two cases:
+
+- **`aria-hidden="true"`** (and the spec-truthy `{{true}}` / `{{"true"}}` forms) — the author has explicitly removed the element from the accessibility tree, so a "non-interactive element with handler" is moot; AT users won't encounter it either way. The rule additionally treats valueless `aria-hidden` and `aria-hidden=""` as opt-out (see caveat below). Explicit `aria-hidden="false"` / `{{false}}` still flags.
+- **`role="presentation"` / `role="none"`** — the author asserts the element is decorative. We accept `role="presentation"` and `role="none"` (case-insensitive, first recognized token of a space-separated role list per WAI-ARIA first-recognized-token rule) — a deliberate superset of [jsx-a11y's exact-match `isPresentationRole`](https://github.com/jsx-eslint/eslint-plugin-jsx-a11y/blob/main/src/util/isPresentationRole.js) for consistency with [WAI-ARIA 1.2 §4.1](https://www.w3.org/TR/wai-aria-1.2/#host_general_role) role-fallback semantics.
+
+The valueless `aria-hidden` case (e.g. `<div aria-hidden>`) is [genuinely contested](https://www.scottohara.me/blog/2018/05/05/hidden-vs-none.html) — jsx-a11y, vue-a11y, axe-core, and the WAI-ARIA spec take four different positions on whether it counts as "hidden". This rule leans toward fewer false positives: flagging a handler on an author-decorated element creates friction more often than it catches real bugs.
+
+### Related checks outside this rule's scope
+
+- **`role="presentation"` on focusable elements** — per [WAI-ARIA 1.2 §4.6 Conflict Resolution](https://www.w3.org/TR/wai-aria-1.2/#conflict_resolution_presentation_none), browsers ignore `role="presentation"` on focusable elements. [axe-core's `presentation-role-conflict`](https://dequeuniversity.com/rules/axe/4.10/presentation-role-conflict) flags this pattern as an authoring error. This rule does not detect the conflict: the escape hatch check runs before `isInteractive(node)`, so a focusable element with `role="presentation"` returns early and is silently exempted. Interactive-handler cases on plain `<button>` / `<a href>` etc. are still flagged normally when they lack the presentation/none opt-out. If you want to catch the authoring error itself (role=presentation on a focusable element, which has no effect at runtime), layer axe-core or a dedicated rule on top.
+- **Click handler on a non-focusable decorated element** — e.g. `<div role="presentation" {{on "click"}}>`. Our escape hatch silences this by design (jsx-a11y-compat). [axe-core's `click-events-have-key-events`](https://dequeuniversity.com/rules/axe/4.10/click-events-have-key-events) is the complementary check. If you want strictness, layer it on top.
