September 2025: Stabilized shipment workflow in UserOfficeProject/user-office-core by removing an unnecessary event listener in the shipment update path. This targeted bug fix reduces side effects and redundant processing when shipment statuses change, improving reliability and performance of shipment-related processes. The change was implemented via a focused cleanup commit that removes the PROPOSAL_SAMPLE_REVIEW_SUBMITTED listener from updateShipment, contributing to more predictableshipments and lower support overhead.

August 2025 highlights for UserOfficeProject/user-office-core: Delivered two high-impact changes that improve data integrity and data retrieval accuracy. Implemented an entityType filter on getWorkflow in both frontend and backend to ensure only workflows matching the specified entity type are retrieved, enhancing data safety for experiments and proposals. Fixed a critical migration-time issue by cleaning up active templates that reference old PDF templates before deleting the template group, preventing foreign key constraint errors during database patches. These changes improve migration reliability, data integrity, and cross-layer consistency, delivering measurable business value in safer workflows and more reliable migrations.
