Research direction

Start by reproducing the reported save operation in MaterialFiles: open an Excel file from an SMB share with Microsoft Office or M365 Copilot, then attempt to save it. The issue provides no source file, test, or entry point, so trace the SMB-backed file handling from that reproduction; done means the same file can be saved successfully without the reported error.
