I.II Core feature maintenance and updates

This work was carried out continuously over an 8-month period and involved the entire product team. Tasks were prioritized and executed based on real-time needs — such as partner integration updates, user-reported issues, and adjustments required due to the development of new features impacting existing functionalities.
Given the high volume and ongoing nature of these tasks, it is not practical to list every individual item here. However, we have included links to our public GitHub repositories, where all activities are transparently documented for anyone who wishes to review them in detail.
