- Updated test files to collect events first and sort them by their CreatedAt timestamp before processing, ensuring events are handled in chronological order. - Removed redundant error checks for scanner errors after event processing. - Enhanced clarity and maintainability of event handling in tests across multiple files, including export, fetch, and query tests. - Adjusted expected index counts in tests to reflect changes in event structure and processing logic.
