## Why Network access and Unix-socket allowlists must not let commands with filesystem restrictions reach the privileged app-server RPC transport. ## What changed - Bind Unix control sockets in a fixed, user-owned directory with mode `0700`, independent of environment settings, and expose the advertised paths as symlinks. Preserve existing parent permissions, reject unsafe parents, and serialize socket setup and publication. - Mask the socket directory in Linux bubblewrap sandboxes after each bind that exposes it. Reject host mount aliases and nested mounts that compromise isolation. - Deny access to the directory and outbound connections to its sockets in macOS Seatbelt policies, including when network access or Unix-socket allowlists grant broader access. - Require bubblewrap for filesystem-restricted Linux execution. Users with `features.use_legacy_landlock` enabled must disable it for these policies. ## Testing Add regression coverage for direct and symlink socket access, hardlink attempts, Linux host-process links and bind-mount aliases, and continued use of unrelated and sandbox-local sockets. Add transport coverage for parent permissions, concurrent restart after a stale symlink, and cleanup that preserves a replacement at the advertised path.
