Worked on the PathOfBuildingCommunity/PathOfBuilding repository, focusing on refining game logic and user interface elements using Lua and software architecture principles. Addressed a critical edge case in Impale DPS calculations by ensuring that zero or non-positive durations now explicitly yield zero DPS, supported by comprehensive regression tests for calculation accuracy. Enhanced the sidebar statistics display by implementing a compact number formatting toggle with dynamic suffixes, improving clarity and user experience. Also resolved a CalcOffence indentation issue and improved breakdown notes, contributing to code readability and maintainability. Emphasized unit testing throughout to ensure reliability and consistent behavior across new and existing features.
