December 2025 focused on reliability, performance, and integration for ERAS frontends. Key enhancements include robust polls error handling to prevent infinite spinners when polls are null; a validation fix ensuring non-empty poll names are included in evaluation submissions; a new NotifyService to standardize success/error messaging across evaluation forms; PollFilters prefill/caching to speed dynamic report generation; a dedicated UserDataService to manage Keycloak user data for profile management and session handling; navigation and routing improvements with a collapsible sidebar and updated Summary Charts routes; and code cleanup/refactoring to rename heatmap components to charts. ERAS submodule version bumps aligned backend and ERAS-FE references across sprint weeks. Impact: fewer user-facing errors, faster report generation, a cleaner codebase, and scalable patterns for authentication data management and UI navigation.
