 ### Key Patterns
 1. **Shared Types**: All API types are defined in `fmo_api_types` and used by both frontend and backend
 2. **Database Migrations**: Version-controlled SQL migrations in `fmo_server/schema/` (v0-v8)
 3. **Background Monitoring**: `FederationObserver` spawns tasks to monitor multiple federations concurrently
-4. **State Management**:
-   - Backend: Shared app state with Arc/RwLock for thread safety
-   - Frontend: Leptos signals and resources for reactive updates
+4. **State Management**: Backend uses shared app state with Arc/RwLock for thread safety
 5. **Error Handling**: Custom `AppError` type wrapping `anyhow::Error` for consistent error propagation
 
 ### Environment Configuration

 - **Federations API** (`/federations/*`): Unstable API for federation monitoring data
 - **Admin endpoints**: Require bearer token authentication via `FO_ADMIN_AUTH`
 
-### Frontend Development
-The frontend uses Leptos with WASM compilation. Components are organized by feature:
-- `src/components/federations/` - Federation list views
-- `src/components/federation/` - Single federation details
-- `src/components/nostr/` - Nostr integration views
-
-Use `just serve_frontend` for hot-reload development with Trunk.

 ### Database Schema
 PostgreSQL with materialized views and complex indexes. Key tables:
 - `federations` - Federation configurations
