    The peer-cli harness now exposes `cancel-download` so cancellation scenarios

-   Decide how the UI labels this state. It is installed but not downloaded, so
-   “Local only” is technically correct, but users may need a clear affordance
-   like “Installed, not shareable”.
+   The UI now keeps streamed installs in the installed visual state while making
+   the sharing limitation explicit: cards show `Not shareable`, and the detail
+   modal status shows `Installed, not shareable`. Downloaded-and-installed games
+   keep the normal `Installed` label.
 
 My recommended next slice: make the provider abstraction final-ish, then
 implement a real one-pass provider. Everything else builds cleanly on that.
