Delivered a UI-focused bug fix for the Workspace Filter Screen in the ivis-weko3-dev/weko repository, improving readability and overall user experience. The change updates the white-space CSS to allow text wrapping, resolving long-label truncation and reducing user confusion. This fix aligns with issue #56537 and was implemented with minimal risk to other UI components.

October 2025 highlights the stabilization and reliability enhancements to the bulk indexing workflow in RCOSDP/weko. Key work focuses on pre-checking RabbitMQ connectivity before initiating bulk indexing, refined error reporting and logging for indexing operations, robust version synchronization logic, and SQLAlchemy rollback handling. Additionally, test coverage for exception scenarios in the indexing API was expanded (including updates to test_api.py). These changes collectively improve resilience, observability, and data freshness, reducing failed jobs and speeding incident response across indexed datasets.

September 2025 (RCOSDP/weko) focused on strengthening indexing reliability and data integrity in the search pipeline. Key features delivered include substantial improvements to the indexer error handling and bulk reindexing workflows, with enhanced reporting and test coverage. A major bug fix corrected the indexing version synchronization by switching Elasticsearch metadata from revision_id to version_id, eliminating data inconsistencies. The work reduced failure modes in bulk operations, improved traceability through indexing IDs, and increased confidence in data synchronization. Technologies demonstrated include Invenio indexer, Elasticsearch metadata/versioning, Python unit testing, test-driven development, and robust API fixes.
