+# CUA Settings Empty Message Plan
+
+## Scope
+
+The issue is isolated to the static Computer Use plugin settings UI in
+`plugins/cua/settings/assets/index.js`.
+
+## Implementation
+
+- Keep `setText()` as the fallback helper for data rows that should display `Unknown`.
+- Change `setMessage()` so the transient status/error area writes the provided text verbatim and
+  allows an empty string after success.
+- Add a jsdom regression test that loads the static settings script, invokes the Check button, and
+  verifies the message area is empty after a successful permission check.
+
+## Test Strategy
+
+- Run the focused renderer test for the plugin settings script.
+- Run repository-required formatting, i18n, and lint checks.
+
+## Risks
+
+- Low. The change only affects the bottom message element and keeps status rows unchanged.

+# CUA Settings Empty Message
+
+## User Story
+
+As a user checking Computer Use plugin permissions, I want the plugin settings page to show the
+permission results only in the status rows so that a completed check does not leave an unrelated
+`Unknown` message at the bottom of the page.
+
+## Acceptance Criteria
+
+- A successful permission check updates the Accessibility and Screen Recording rows.
+- After a successful permission check with no diagnostic error, the bottom message area is empty.
+- Runtime fields can still show `Unknown` when their underlying status values are unavailable.
+
+## Non-goals
+
+- Redesigning the plugin settings layout.
+- Changing runtime or permission detection behavior.
+
+## Open Questions
+
+None.

+- [x] Confirm the source of the bottom `Unknown` message.
+- [x] Update message rendering to allow an empty success state.
+- [x] Add focused regression coverage.
+- [x] Run `pnpm run format`, `pnpm run i18n`, and `pnpm run lint`.
