Remove user, PID, network, mount, UTS, and IPC namespaces. Landlock v5 is now the primary isolation mechanism for filesystem, network, signal, and IPC control. Plain fork() replaces clone() with CLONE_NEW* flags. Minimum kernel raised to 6.12. - Add rlimits module (RLIMIT_DATA instead of RLIMIT_AS) - Add seccomp user notify support (SECCOMP_RET_USER_NOTIF) - Update security tests for new isolation model
Replace manual forAllSystems boilerplate with flake-parts module system and import-tree for auto-discovery of nix modules. - Add nix/toolchain.nix (shared crane/toolchain via _module.args) - Merge checks into nix/packages.nix - Add packages.test-all for full security test suite - Restrict to x86_64-linux (arm not yet supported) - Remove nix/lib.nix, nix/checks.nix, nix/tests/
Rewrite all documentation to reflect removal of namespaces and Landlock v5 as primary isolation mechanism. - Update README: kernel 6.12+, no namespace references - Rename docs/SECURITY.md to docs/SECURITY_MODEL.md - Add SECURITY.md (GitHub vulnerability reporting policy) - Add CONTRIBUTING.md (dev setup, testing guide) - Rewrite ARCHITECTURE.md (lifecycle, diagrams, crate structure) - Add security hardening roadmap (UDP, /proc, PID namespace) - Add CHANGELOG 0.1.1
