July 2025 performance summary: The frontend and backend teams delivered concrete business-value improvements across checkmarble/marble-frontend and marble-backend, focusing on robust rule authoring, workflow reliability, UX polish, and maintainability. Key achievements include the AST Builder and Rule Management Enhancements (switching to the default AST builder component, adapting the builder for workflow usage, highlighting the currently edited rule, improved rule validation and display, and enabling ActionSelection); Inbox Selector and UI Improvements (access-control aware inbox selector, default value handling, aligned action inputs, and removal of the inbox label); Page Alignment and API Page Rework to improve layout consistency and API usability; Biome Library Upgrades and DTO Adapters Improvements to enhance dependency stability and data contracts; and Backend enhancements (Goose Migration Directory documentation, Inbox Auto-Assignable Status Control, and Case Auto Assignment) to improve deployment clarity and automated routing. In addition, QA-focused fixes and cleanup activities (Advanced Workflows QA fixes, removal of adapters from components, and deprecation of SelectWithCombobox) contributed to overall stability. The combined effort reduced rule authoring time, improved workflow accuracy and auto-routing, and strengthened the system’s stability and maintainability.
