During June 2025, Haru Silverdale focused on stabilizing stamp interactions in archived channels for the traPtitech/traQ_S-UI repository. Haru addressed a bug that allowed stamp add and remove actions in archived channels by implementing component-level archiving checks using Vue.js and TypeScript. The solution included blocking these actions and providing clear UI feedback through toast notifications and improved error messaging, ensuring users understood why actions were restricted. Haru also refined the UI codebase with minor formatting cleanups to enhance readability and consistency. This work demonstrated a careful approach to state management and user experience in front-end development.
