Worked on the ROCm/onnxruntime repository to address a critical regression affecting Windows AppContainer environments. Focused on improving path handling by implementing a fallback mechanism for the WeaklyCanonicalPath function, which resolved model load failures caused by access denial errors. Utilized C++ and Windows development expertise to ensure path canonicalization preserved volume identity, leveraging GetFinalPathNameByHandleW and specific path prefixes for cross-volume safety. Developed and integrated targeted unit tests to validate the new fallback behavior and edge cases, reinforcing the reliability of external data path validation. This work enhanced ONNX Runtime stability and build reliability in constrained Windows environments.
