Worked on the openclaw/openclaw repository to enhance the stability and security of static asset serving, focusing on cross-platform compatibility and file system operations. Addressed a Windows-specific issue where fs.lstatSync could return a device ID of zero, causing identity checks to fail silently and impacting the Control UI. The solution involved updating the sameFileIdentity logic in TypeScript to fall back to inode-only comparison when necessary, preserving TOCTOU protection and ensuring reliable asset delivery. This targeted bug fix reduced asset-serving regressions and improved the resilience of static file handling, leveraging Node.js and TypeScript for robust, maintainable cross-platform support.
