Clean-room Rust reimplementation of glibc with an opt-in Transparent Safety Membrane, loaded via LD_PRELOAD. 4,119 exported symbols classified; 2,829 native Rust + direct syscalls (68.7%), the rest host-backed. Two runtime modes (strict/hardened); x86_64 primary, aarch64 covered. Membrane coverage is path-specific, not universal.
