 The optional browser contribution mounts the native provider's permission Remote and reuses the Plugins activation and configuration slots. The four setup rows remain visible while unknown fields use placeholders; the same permission-management guidance remains visible while queries settle and after access is granted, including when the text wraps. The default-mode form, runtime configuration, system checks, application decisions, and application icons fill in as each query completes. Application names and actions do not wait for icons; icon positions retain their space. User actions run in order without waiting for pending observation queries. Disposal waits for both actions and queries to settle before releasing the separately owned Remote mount. Known query errors and read-only settings stay visible while management operations or retries run, with their actions disabled. Query errors stay with the affected section, and activation guidance depends only on system checks. The injection layer observes Plugin Manager operations independently of the page. Bundle and row changes pause all four queries and invalidate in-flight results; settlement refreshes observations even after the page closes. Last known errors remain until a successful read. Disposal discards late results. The controller consumes the generated `ctx.remote.cuaAccess` namespace directly and handles unsuccessful Remote results in its existing query and action paths. It projects queries into the page and setup dialog; reconnects and updates to the Host-reported settings namespace refresh it. Operation notices live in the shell overlay, so closing the page does not remove them. The provider owns permission checks, persisted decisions, and cancellation; the browser owns no authorization state.
 
-The detail page reads the effective default (`selectedDefault ?? default`) from the existing `configForms` service. The default button writes only `selectedDefault` through the form's revision-checked settings path. The execution-mode row uses CUA's `ptcConfiguration()` and `enablePersistentPtc()` controls: the Host edits the selected evaluator’s persistence configuration through the existing configuration editor, preserving its ordinary Loader reload lifecycle. Permission checks and runtime state settle independently. Loading, read-only and unavailable settings cannot submit a change; a failed write remains beside the setting for retry.

The execution-mode row uses CUA's `ptcConfiguration()` and `enablePersistentPtc()` controls: persistence follows the loaded runtime's `retainsState`. Enabling persistence preserves an active Script evaluator and writes `executionMode` and `scriptPersistence` together through the configuration editor; other modes select the retained REPL with Script persistence disabled. The ordinary Loader reload lifecycle applies. Permission checks and runtime state settle independently.
