Userspace macOS ARM64 → Linux aarch64 translation layer (CLI-first, no JIT). Load Darwin Mach-O on Linux aarch64, map a freestanding libSystem , translate BSD syscalls, and run real guests (clang probes, 7-Zip 7zz , curl , threads). Live execution Linux aarch64 (bare metal, VM, Colima/Docker) Dry-load / inspect Any host (including macOS) Design reference docs/ What works Verified on Docker/Colima and UTM (Linux aarch64). Install once: cargo install kakehashi # or from a checkout: cargo install --path crates/kh-cli --force kh bottle ensure kh install 7zip # Darwin 7zz → guest /usr/local/bin/7zz kh install curl # Darwin curl → guest /usr/local/bin/curl Relative -o / archive paths resolve against the host CWD of the kh process (create parent dirs yourself, or rely on auto-mkdir for O_CREAT ). Through the bottle, /Volumes/linux/… bridges to the host root ( / → host / ).…
