+- Run **all** checks locally. Use the root `just` helpers so you stay consistent with the rest of the workspace: `just fmt`, `just fix -p <crate>` for the crate you touched, and the relevant tests (e.g., `cargo test -p codex-tui` or `just test` if you need a full sweep). CI failures that could have been caught locally slow down the process.
