 3. **Operations Pattern**:
    - Each API resource has its own operations class (e.g., `UserOperations`, `MeetingOperations`)
-   - All operation classes inherit from `BaseOperations` which provides lazy-loaded user ID
+   - Sync operations in `src/bloomy/operations/` inherit from `BaseOperations`
+   - Async operations in `src/bloomy/operations/async_/` inherit from `AsyncBaseOperations`
+   - Both inherit from `AbstractOperations` which provides shared logic
    - Operations are accessed via client attributes: `client.user`, `client.meeting`, etc.
