## What changed
- Add the macOS-only `allow_symlinked_codex_home` user setting. When enabled in the execution host's `$CODEX_HOME/config.toml`, writable roots at or beneath that home may traverse symlinks.
- Keep the exception disabled by default and prevent project config, command-line overrides, and ignored user config from enabling it. Other writable roots remain subject to symlink checks.
- Propagate the resolved setting through local, interactive, and exec-server sandbox paths, including `CODEX_HOME` aliases.
- Explain the opt-out in symlink rejection errors, including that it trusts targets outside `CODEX_HOME` and targets that change between commands.
## Testing
- Add macOS coverage for shell commands, patches, filesystem helpers, process execution, and interactive startup with enabled, disabled, aliased, and out-of-scope homes.

## What changed
Add macOS-only integration coverage that runs commands under the production
Seatbelt policy and verifies:
- deny globs protect matching files, directory ancestors, symlink aliases, and
paths created after policy application;
- protected directories cannot be moved, replaced, or exchanged across
writable roots; and
- standard read-only and workspace-write profiles continue to allow expected
filesystem operations.
