Jorge Fabila focused on stabilizing the UI processing state in the Stirling-Tools/test-dont-use repository, addressing a bug that previously allowed duplicate submissions and inconsistent button states. He implemented logic in JavaScript to hide the 'bored waiting' button once a processing request completed, regardless of outcome, and ensured the 'submit' button was disabled during processing and re-enabled afterward. This approach improved the user experience by eliminating race conditions and preventing duplicate actions, enhancing the robustness of the front end. Jorge’s work demonstrated attention to UI state management and traceability, with changes directly linked for future audits and debugging purposes.
