## Summary - Coerce Windows `workspace-write` configs back to read-only, surface the forced downgrade in the approvals popup, and funnel users toward WSL or Full Access. - Add WSL installation instructions to the Auto preset on Windows while keeping the preset available for other platforms. - Skip the trust-on-first-run prompt on native Windows so new folders remain read-only without additional confirmation. - Expose a structured sandbox policy resolution from config to flag Windows downgrades and adjust tests (core, exec, TUI) to reflect the new behavior; provide a Windows-only approvals snapshot. ## Testing - cargo fmt - cargo test -p codex-core config::tests::add_dir_override_extends_workspace_writable_roots - cargo test -p codex-exec suite::resume::exec_resume_preserves_cli_configuration_overrides - cargo test -p codex-tui chatwidget::tests::approvals_selection_popup_snapshot - cargo test -p codex-tui approvals_popup_includes_wsl_note_for_auto_mode - cargo test -p codex-tui windows_skips_trust_prompt - just fix -p codex-core - just fix -p codex-tui
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
