Aug 1, 2025August 2025 performance summary for National-Digital-Twin/LISA: Delivered a targeted set of user-facing UI improvements, reliability hardening, and data integrity fixes that drive faster decision-making and reduce data risk. Key features include Sort & Filter UI enhancements (log entries and incidents with accessibility tweaks), Incident screen enhancements (ARIA improvements and updated Overview), S+F Time Picker, and keyword search in tasks/Overview to accelerate data discovery. Major reliability work includes hardening the Stage Change process and wiring the Tasks widget to the Tasks hook to ensure robust end-to-end data flow. Critical bug fixes addressed deduplication across modules, home-page task count accuracy (DPAV-1432), several SQ-related issues, restoration of log-entry header links, and login redirects after 403/401. Additional stabilization encompassed code-quality cleanup, removal of debug logs, and restoration of the GitFlow release process plus workflow updates. Tech focus areas included React/JS UI, accessibility (ARIA), deduplication strategies, error handling, and SQL-level dedupe patterns. Business impact includes reduced data duplication risk, smoother user workflows, and more reliable, scalable releases.
