HelcticOne kernel, every ABI

A multi-OS syscall personality kernel. Run unmodified Linux, Windows, Darwin and BSD binaries alongside a native Rust microkernel — with a Zig personality layer doing the translation.

🧬

Personalities, not emulation

Each process carries a personality (Linux, Windows, Darwin, *BSD, or native). The kernel dispatches syscalls through the matching ABI table — in-kernel translation, no userspace VM.

How personalities work

🦀

Rust core, Zig translation

The kernel core is Rust (memory, scheme/VFS, contexts). The personality layer is Zig, compiled to a static library and linked via a flat C ABI kernel-ops callback table.

The FFI boundary

🔎

ELF / PE / Mach-O aware

Personality is detected from the binary itself — ELF OS/ABI, PE machine type, Mach-O cputype — during exec(), before the first return to userspace.

Specs from source

The specification pages are generated directly from the kernel source by an autodoc tool, so the API reference never drifts from the code.

Scheme-based VFS

Everything is a scheme. The filesystem layer (including btrfs via Zig) and devices are exposed through a uniform open/read/write/close surface.

Honest roadmap

Helctic is early. The docs track exactly what works, what is stubbed, and what is planned across the M1–M5 milestones.
