Could you build this?
Partial Implementing safe, transactional file system modifications with APFS copyfile CoW calls and reliable atomic rollbacks on macOS requires low-level POSIX and Darwin system programming.
What it would actually take: A native Swift/Objective-C macOS app leveraging Darwin's `copyfile(3)` system call with `COPYFILE_CLONE` flags to achieve zero-space Copy-on-Write extents on APFS volumes. The difficult aspects involve managing file descriptors safely, handling edge cases across cross-volume boundaries (fallback to physical stream copies on FAT32/exFAT), tracking complex file metadata/permissions, and maintaining an atomic write-ahead journal for error recovery and full undo operations.
