Ivan Zheng contributed to the PMKS-Web/PMKS-Refactor repository by developing features that improved both user experience and maintainability. He implemented checksum-based detection for legacy PMKS URLs, enabling the system to identify and safely redirect users navigating older links, while providing clear notifications about data transfer or incompatibility. In addition, Ivan introduced undo and redo functionality for link locking actions, updating the undoRedoService to capture and reverse lock state changes, which enhanced the reliability of the edit panel. His work leveraged Angular, TypeScript, and state management techniques, demonstrating a thoughtful approach to backward compatibility and robust front-end engineering.

October 2025 monthly summary for PMKS-Refactor focusing on delivering a robust and reversible link-state editing experience. Implemented undo/redo support for lock/unlock actions on links, updated the undoRedoService to handle lockLink actions, and captured lock state changes to ensure reversibility. This work reduces risk of unintended edits, improves edit panel usability, and aligns with the refactor goals for maintainability and scalability.
