Summary
This is a testing guide for developers working on Codex TUI itself. It walks you through the proper way to spin up the TUI interactively with trace logging enabled, routing logs to a temp directory for debugging, and the somewhat finicky detail about sending test messages in two separate writes instead of one burst. If you're contributing to or debugging Codex TUI, this gives you the right incantations. If you're just using Codex as an end user, you can skip this one entirely.
