(staged as /lib/init/init-main.js); point bundle-kernel-init and verify scripts at the new path. Wire curl, wget, openssl, ssh-keygen, and tar through coreutils and booter host delegates with booter-side CLI helpers; refresh related bins, bare manifest, shell completion, and man DB (kernel + seeder). Add booter support modules for ACL evaluation, audit chain, secret handles, peer admission, replication priority, process table, swarm lifecycle, boot-graph proc, metrics, monotonic time, protomux alias registry, and swarm peer policy; extend extension resolver, VFS, swarm connection managers, IPC, identity-account, and initd. Harden bare-os-bare-libs build on esbuild failure; add verify scripts for extension manifest schema and runtime incomplete markers; extend ctx API typings, gen-ctx-client-stub, and verify-ctx-dts. Update boot hook fragment, bundled init.js, handbook and reference docs (incl. kernel security and VFS path classes).
