@@ -241,3 +241,9 @@
 ### Step 39 - Android scope / remove calls UI
 - Removed chat top-bar `Call` action from Android `ChatScreen`.
 - Updated Android UI checklist wording to reflect chat header without calls support.
+
+### Step 40 - Invite deep link flow (app links)
+- Added Android App Links intent filter for `https://chat.daemonlord.ru/join...`.
+- Added invite token extraction from incoming intents (`query token` and `/join/{token}` path formats).
+- Wired deep link token into `MessengerNavHost -> ChatListRoute -> ChatListViewModel` auto-join flow.
+- Removed manual `Invite token` input row from chat list screen.
