## Summary - Retire the experimental TUI2 implementation and its feature flag. - Remove TUI2-only config/schema/docs so the CLI stays on the terminal-native path. - Keep docs aligned with the legacy TUI while we focus on redraw-based improvements. ## Customer impact - Retires the TUI2 experiment and keeps Codex on the proven terminal-native UI while we invest in redraw-based improvements to the existing experience. ## Migration / compatibility - If you previously set tui2-related options in config.toml, they are now ignored and Codex continues using the existing terminal-native TUI (no action required). ## Context - What worked: a transcript-owned viewport delivered excellent resize rewrap and high-fidelity copy (especially for code). - Why stop: making that experience feel fully native across the environment matrix (terminal emulator, OS, input modality, multiplexer, font/theme, alt-screen behavior) creates a combinatorial explosion of edge cases. - What next: we are focusing on redraw-based improvements to the existing terminal-native TUI so scrolling, selection, and copy remain native while resize/redraw correctness improves. ## Testing - just write-config-schema - just fmt - cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs -p codex-core - cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs -p codex-cli - cargo check - cargo test -p codex-core - cargo test -p codex-cli
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.
When using the workspace-write sandbox policy, the Seatbelt profile allows
writes under the configured writable roots while keeping .git (directory or
pointer file), the resolved gitdir: target, and .codex read-only.
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.
