WHENWhen implementing API endpoint responses

ACTIONWrap each responses in {'result': ..., 'message': ...} structure

CONSEQUENCEFrontend clients expect the standard wrapper format. Missing 'result' or 'message' keys causes client-side parsing errors and unhandled exceptions in consuming applications.

WHENWhen implementing async API endpoints

ACTIONDecorate endpoints with @async_api_call() and return {'result': ..., 'message': ...} dict

CONSEQUENCEWithout the decorator, async tasks cannot be tracked via query_tasks_outcome(). Clients receive incomplete responses and have no way to poll for completion status.

WHENWhen handling user login operations

ACTIONProtect login operations with @login_lock() decorator to prevent race conditions

CONSEQUENCEConcurrent login attempts without the lock cause race conditions in user unlock logic. Multiple greenlets may simultaneously modify user session state, leading to authentication bypass or data corruption.
