During November 2025, Thvk developed and delivered a new Lua API, core.path_exists(path), for the luanti-org/luanti repository. This feature allows Lua scripts to check whether a given filesystem path exists, supporting both files and directories, and enables scripts to branch logic and handle errors more robustly. Thvk implemented the API as a focused, single-commit change, demonstrating disciplined version control and attention to integration quality. The work involved C++ programming for the backend and Lua scripting for the interface, resulting in improved reliability and maintainability of filesystem operations within automation workflows. No major bugs were recorded during this period.
