 - A missing command handler is surfaced by the host as a retryable reload error;
   menu clicks must never fail silently.
 - A registered handler's rejected promise is not swallowed: the host logs the

+  plugin id, command id, status, reason and message, then presents a generic
+  retryable error without raw payloads. In
   particular, return/await `services.windows.open(...)` so native-window
   failures follow this path.
+- An open/focus handler returns `status: "opened"` whether `alreadyOpen` is
+  `false` (new window) or `true` (existing window focused). Neither success
+  produces an alert.
+- Keep diagnostic views reachable when optional executables such as Git, ADB or
+  Gradle are missing. Let the view explain that degraded state instead of
+  skipping the menu action before opening it.
 - A handler owns precondition checks and feedback. See
   [Commands And Feedback](commands-and-feedback.md).
 - Menu item `when` expressions are evaluated by the host; unsupported or false
