March 2025: Delivered core UI improvements and form workflow enhancements in the orchestrator-ui-library, with a strong emphasis on business value and maintainability. Key deliverables included Pydantic Forms Integration for the Modify Note workflow (UI wiring, dependency updates, and loading state) and an upgrade of pydantic-forms, alongside typing improvements across the codebase. Stability and accessibility were improved by fixing console errors on fill-rule rendering and addressing aria-label warnings; UI refinements added a styled footer and an Elastic UI textarea, while removing several TypeScript exceptions. Release readiness and internationalization were advanced with translations across locales and new changesets for release notes, plus PR comments improvements. Groundwork for ESui FileUpload field and API endpoint integration is in progress (WIP) with field migrations planned for the next sprint.
