For 2025-10, key reliability improvements were delivered in the qor5/admin Worker UI by addressing auto-refresh and portal synchronization. Fixed worker auto-refresh interval and portal refresh after job status changes, ensuring UI updates for new, running, scheduled, and completed jobs. Centralized refresh logic to minimize unnecessary refreshes and keep portal data aligned with job state. These changes improve data accuracy, reduce stale UI, and enhance user trust in job lifecycle visibility. Commits ae6ed0bf0612c324cfaba2bb9d0bbc682f880a7b; 850c6ca08692587ca5a67410fd2e0c357c1e907e.
