Monthly performance summary for 2025-10: In Autonomy-Logic/openplc-editor, delivered key UX and stability improvements to the ladder editor by implementing Rung Visibility Management and stabilizing the project-open logic. The team now tracks per-rung open/closed states for clearer diagrams and consistent behavior across project opens. A bug fix reverts complex visibility changes on project open to a boolean-based approach, removing handleRungIsOpen and ensuring getIsRungOpen always returns a boolean. These changes reduce user confusion, simplify future maintenance, and contribute to more reliable project opens. Technologies/skills demonstrated include UI state management for ladder editing, focused code refactoring to simplify visibility logic, and clear commit-based traceability.
