Owner-only. When `public: true`, anyone with the URL can open the live hosted App Viewer with no login and receives Viewer access (`app:read` only). Public visitors can read App data but cannot run mutating operations or edit source. Template and Listed are separate settings. When `public: false`, anonymous visitors can no longer open the hosted App. Existing App data is retained. Idempotent calls are no-ops.

<Operation source="reference" id="set-app-public" />
