 ## Knowledge Gaps
-- **354 isolated node(s):** `main`, `package:off_chat/src/app.dart`, `OffChatApp`, `_OffChatAppState`, `initState` (+349 more)
+- **340 isolated node(s):** `main`, `NotificationService`, `package:off_chat/src/app.dart`, `OffChatApp`, `_OffChatAppState` (+335 more)
   These have ≤1 connection - possible missing edges or undocumented components.
-- **Thin community `Community 28`** (2 nodes): `constants.dart`, `MeshConstants`
+- **Thin community `Community 27`** (2 nodes): `constants.dart`, `MeshConstants`
   Too small to be a meaningful cluster - may be noise or needs more connections extracted.
-- **Thin community `Community 29`** (2 nodes): `extensions.dart`, `title`
+- **Thin community `Community 28`** (2 nodes): `extensions.dart`, `title`
   Too small to be a meaningful cluster - may be noise or needs more connections extracted.
