-   - **Next:** 72 screens remain. `Amethyst.instance` reads block 16 of them, and
-     `LocalPreferences` another 5. Smaller exits: `UpdateZapAmountDialog` (biometrics),
-     `NestActivity` (PiP), `CalendarTimeFormat`, `GalleryThumb` (media3),
-     `AccountSessionManager`, the Blossom health probe, `ReactionsRow`, `NappletLauncher`
-     and the call permissions.
+   - **Wave 9 (2026-09-30):** `AppServices` gained `appStores`, `torBootstrapped` and
+     `cachedPlaceName`; the host gained the backed-up-keys flag. `rememberDeviceAuthenticator`
+     wraps BiometricPrompt with the keyguard fallback. `CalendarTimeFormat` is shared on
+     `DateSkeletonFormatter`. Moved: search, the long-form composer, the calendar collection

+     - The call screens.
+     - The WebView browser and napplet launcher.
+     - The osmdroid geocache map.
+     - Health Connect workouts.
+     - The Cordn backup/migrate file flows.
+     - Share-as-image (bitmaps).
+     - `AccountSessionManager` (login and sign-up).
+     - The Blossom health probe.
+     - `AppSettingsScreen` (`BuildConfig`).
+     Each needs a slot or a port of its own, so step 7 can start alongside them.

 8. **The app root port** and the new JVM shim. Then the Desktop feature inventory, and
    retiring the old `desktopApp`.
